We’re no longer just a Web site as we added a bunch of things like Bulletins (plain text, accessible from the command line or editors directly), Gemini, and IPFS. We’ve also moved our IRC channels to our own network. This is the direction we’ve long wanted to take; lock-downs have given us the luxury of extra time. Not many sites manage to exceed 15 years in daily activity. 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇Archived Historical Documents⦈ To celebrate this milestone we now have this_new_(and_Gemini-only)_section where we archive important documents. It will expand over time and, as the video above explains, a lot of this material lands in Gemini Space (or Geminispace) for the very first time. We need to grow and enrich that Internet space; we invite more people to join, not just as readers but also as authors. Gemini is far simpler in every way than running/managing/maintaining a Web site, it’s just a little different because it is new and not yet ubiquitous. It should be taught everywhere, especially in schools (it’s simple enough that even elementary school pupils can do it). We’ve meanwhile made further enhancements to the_“stats”_page, as will later become visible in_Git_tracking. █ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⠀⠀⠀⠀⢀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⠀⠀⠀⠀⢀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⢀⣂⣇⣂⠀⠀⠀⠀⡀⠒⢰⠀⠔⠒⡄⠠⠒⠤⠒⠄⢰⠀⡆⠒⠄⢰⠀⠀⢺⠂⠠⠒⢀⢀⠐⠂⠀⠔⠂⡀⠠⠒⢠⢀⠐⠂⡆⢸⠐⢢⠐⡗⠂⡔⠂⠀⠀⠠⠒⠢⠀⡄⠂⠔⠒⠄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠂⠇⠂⠀⠀⠀⠀⠣⠀⢼⠀⢍⣉⠁⠀⠀⠀⠀⠀⠸⠀⡇⠀⠀⢸⠀⡀⠸⡀⠩⣉⡩⠘⢀⡀⠀⠀⠀⠇⠀⠀⠸⠘⠄⠠⡇⠸⠀⠸⠀⢃⡀⢈⡁⠀⡀⠠⣀⡠⠀⠇⠀⠂⠀⠄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠐⠒⠊⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠒⠒⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠐⠒⠂⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⣴⢷⡀⠀⠀⠀⠀⠀⠀⡀⠀⢸⡇⢀⠀⠀⠛⠀⠀⠀⠀⠀⠀⢀⠀⠀⠀⢀⠀⣿⠀⠀⠀⣾⡆⠀⠀⣿⠀⠛⠀⠀⢀⠀⠀⣴⡄⠀⠀⢀⠀⠀⠀⠀⠀⠘⠃⠀⠀⡀⠀⠀⠀⡀⠀⢰⡇⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⣼⣏⣘⣷⡀⢸⡟⠋⢰⡟⠉⠃⢸⡟⠙⣿⠀⣿⠈⢿⡀⣼⠃⣾⣋⣹⡆⣾⠋⠙⣿⠀⠀⠀⣿⡷⠶⠶⣿⠀⣿⠀⢾⣍⣙⠈⣿⡏⢁⣾⠉⢻⡆⢸⡟⠋⢸⡇⢰⡟⠉⠃⢘⣉⣹⡇⢸⡇⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠸⠏⠉⠉⠙⠷⠸⠇⠀⠘⠷⠶⠆⠸⠇⠀⠿⠀⠿⠀⠈⠿⠃⠀⠻⠶⠶⠆⠹⠷⠖⠿⠀⠀⠀⠻⠇⠀⠀⠿⠀⠿⠀⠶⠤⠿⠀⠹⠧⠄⠻⠦⠾⠃⠸⠇⠀⠸⠇⠘⠷⠶⠆⠸⠧⠾⠇⠸⠇⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⣶⠶⢦⣤⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⣿⠀⠀⢹⡇⢠⡶⠓⣶⡀⣴⠞⠲⠀⣶⠀⢰⡆⢰⡶⠺⣦⠖⣶⡄⣰⠞⢲⡄⢰⡶⠺⣶⠐⢿⡗⠂⣶⡓⠶⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⣿⣤⣤⡾⠃⠸⣧⣤⡿⠃⢿⣤⣤⠄⣿⣤⢼⡇⢸⡇⠀⣿⠀⢿⡇⠻⣯⣩⡅⢸⡇⠀⣿⠀⢸⣧⡀⣬⣩⡷⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠠⡀⢀⠀⠀⠀⠀⠀⠀⠀⠀⢀⠀⠀⠀⠀⢤⠤⠀⠀⠀⠀⡄⠀⠀⠠⠀⠀⠀⠀⠀⡀⠀⠀⠀⢠⢠⠀⢠⠀⠀⠠⠀⠀⠀⢠⠀⠀⠀⠀⡄⠀⠀⠀⠀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠃⠀⠀⠁⠸⢉⠇⣝⡇⣏⡁⠪⡁⠘⡁⣏⡅⠀⠸⠀⢚⣛⢨⣉⡏⢹⠘⢹⠸⡉⡇⠉⡇⢏⢘⡅⠀⢂⠀⠣⢹⢨⣻⢸⠸⢹⠀⢸⢸⠉⠸⣉⡇⣟⡃⠷⡁⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠉⠀⠀⠀⠀⠀⠀⠀⠈⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⢀⠀⢀⢀⠀⠀⠀⠀⠀⠀⠀⡀⠀⠀⠀⢀⠀⠀⠀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⢸⠒⢺⢰⠰⢄⢘⢰⢐⢴⠂⡆⡂⢂⢤⣼⠀⢰⢐⡧⠂⡆⡆⠲⠀⡆⡆⡆⠂⡦⠄⡆⢰⢸⠰⢴⠀⠀⡢⡆⠢⡄⠀⡇⠐⡤⠦⠆⠂⡆⡆⡇⢰⠴⢐⢔⢸⠀⠀⢰⡖⢰⠀⢰⢰⢰⢐⠄⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠁⠀⠀⠁⠀⠀⠀⠈⠀⠁⠀⠀⠀⠁⠀⠈⠀⠈⠀⠁⠀⠀⠀⠀⠈⠁⠀⠀⠀⠀⠁⠈⠀⠈⠀⠈⠀⠀⠀⠁⠀⠈⠀⠀⠀⠀⠈⠀⠁⠀⠀⠀⠈⠀⠀⠀⠀⠀⠀⠀⠀⠁⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⢀⣀⠀⣀⠀⣀⣀⢐⢀⣀⡀⢀⢠⢀⡀⢀⡀⠀⣀⢀⣀⣀⣠⢀⡀⢀⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⢸⠤⠃⠤⠇⠇⠠⠸⠰⠤⠣⠼⠘⠢⠼⠀⠀⠘⠤⠻⠀⠧⠼⠣⠬⠀⠠⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠠⢤⠄⡄⠀⠀⠀⠀⡠⠤⠀⠀⠀⠀⡄⠀⠀⠀⠀⢠⠀⠀⠀⢀⠀⠀⠀⠀⠀⠀⠀⡄⠀⡀⠀⠀⠀⠀⠀⢠⠤⡄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠸⠀⠇⡇⢗⡃⠀⢧⣀⠨⡻⠈⡁⡇⠇⢗⡓⢇⣹⠸⠨⡛⠾⠀⠨⡺⢸⠉⠶⣁⡇⠀⢇⠈⢸⠸⣚⠀⢸⣉⠇⣕⡇⣔⡁⣗⡇⣕⡇⡏⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⢰⣀⣸⠠⢤⢸⢰⡠⢄⢀⢠⡀⢄⠤⢀⠤⣠⠤⡀⠀⡆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠘⠀⠘⠘⠚⠘⠘⠑⠚⠈⠃⠛⠘⠒⠈⠒⠘⠀⠃⠀⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⢀⣀⡀⡀⠀⠀⠀⠀⢀⣀⡀⡀⢀⢀⠀⢀⠀⢀⠀⢀⠀⠀⠀⠀⠀⠀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⢸⠀⡏⡆⡮⠆⠀⢇⠐⡄⠙⢼⠸⡀⣸⠀⢸⢢⢺⢠⢵⢰⠈⡆⠈⠁⡮⡆⠮⡈⡇⡎⡢⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠠⠒⠳⣄⠀⠀⣎⠑⠂⣇⣀⡀⣀⣀⢀⣀⢐⠀⣀⣀⠀⣀⣀⠀⠀⡃⢀⢀⠀⠀⣀⣀⢀⡀⡀⢀⡀⡂⢀⣀⡀⢀⣀⡀⠀⠀⢀⠄⢄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠐⠒⠔⠁⠀⠀⣌⣉⠆⡇⠀⡇⣖⣺⠸⠇⢸⠀⡇⢸⠘⣄⣸⠀⠀⡇⢈⣲⠄⠀⢇⣀⠰⣒⡇⢸⠀⡇⢸⠀⡇⠣⣀⡇⢀⠀⠉⠤⠔⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠒⠊⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠐⠒⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ䷩ 𝚕𝚒𝚗𝚎 179 ╒═══════════════════ 𝐀𝐑𝐓𝐈𝐂𝐋𝐄 ═════════════════════════════════════════════════╕ (ℹ) Images, hyperlinks and comments at http://techrights.org/2021/11/08/gemini-techrights-org/#comments Gemini version at gemini://gemini.techrights.org/2021/11/08/gemini-techrights-org/ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 11.08.21⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Reminder:_Techrights_is_at_gemini://gemini.techrights.org⠀✐ Posted in Site_News at 4:08 pm by Dr. Roy Schestowitz Summary: Our migration to Gemini is virtually complete (all blog posts, wiki, and more); the World Wide Web isn’t going away, at least not in a matter of years, but we’ve put our eggs also in the gemini:// basket THE world’s “modern” Web browsers are becoming just a monolith; they’re mostly clones of the same thing, which is de facto proprietary with DRM on top. As for Mozilla, it's_acting_like_an_extension_of_GAFAM and Firefox won’t survive this way. It’s not trustworthy, either. 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇Office Space meme: If you could join us in gemini:// gemini.techrights.org ... That would be great⦈ So we need to get off the World Wide Web, however gradually. This can take a long time, but a partial transition is doable. One shouldn’t be required to run a 300MB (or RAM) application with lots of unknown scripts running in the background just to read an article, i.e. about a dozen paragraphs of text. So around the start of this year we launched our Gemini_capsule, knowing Gemini Protocol was still very new albeit approaching finalisation (Solderpunk is working on it this week [1, 2]). Lupa knows close to 1,800 capsules already (latest list as_HTML or as_text; it was around 500 at the same time last year) and it grows each month at a steady pace. As we habitually do, we again invite people to join us in Gemini Space. Advertisers, spies and hostile corporations aren’t there, at least not yet. The artificial limitations and constraints there would handicap their ambitions, regardless. █ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣀⣀⣀⣀⣀⣀⣀⣀⣀⣀⠀⣀⣀⡀⢀⣀⢀⣄⣀⣀⡄⢀⣄⣀⣠⡀⣀⣀⣀⢀⣀⡀⢀⡀⣠⡀⣀⣀⣀⠀⣀⣀⣠⣄⢀⣀⡀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Free/Libre_Software, Microsoft at 8:57 am by Dr. Roy Schestowitz Video_download_link | md5sum bce590b7c85c676c4a9210f152a277cd http://techrights.org/videos/the-github-crisis.webm Summary: Microsoft’s GitHub is going down the drain because of a pile-up of scandals; the reason GitHub’s CEO is thrown under the bus is face-saving efforts or ‘crisis management’ (mitigation) by Microsoft and we_strongly_urge people_to_leave_GitHub_right_now because there’s a lot more to come THIS morning we published Part_5 of an ongoing series about GitHub’s internal affairs [1, 2, 3, 4]. 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇Thank you GitHub⦈ Over the past few years we’ve consistently campaigned for people to abandon GitHub and move to self-hosting or some provider that’s more freedom-respecting. Months ago Microsoft took the gloves off; it made it beyond apparent that it had planned to weaponise GitHub against GPL/copyright/coipyleft. That’s what Copilot is all about. At the moment there’s a crisis at GitHub, but Microsoft tries hard to keep it under the wraps; the removal of Friedman is only the start of it. Next week we’ll publish Part 6 and get a little deeper or closer to the core of the problem. “Git as a command line program keeps things nice and simple, unlike GitHub, which one cannot even control (it is entirely proprietary), so one does not need to dislike Microsoft to fully understand the urgent need to abandon that platform.”The video above is an unplanned and unedited ramble; but the key point is in the latter part, which shows how we’re managing Git graphically, not with a Web GUI but a Gemini GUI that we’ve hand-crafted. Later in the series (maybe the start of next year) we’ll show how easy that is to implement and maintain. A lot of Web interfaces of Git are a bloated mess that’s very expensive and complicated to maintain in the long run. Maybe those take an hour (or a lot less) to install, configure, set up for one’s repository/ies. But all the incidents, upgrades, costs etc. can last years. Git as a command line program keeps things nice and simple, unlike GitHub, which one cannot even control (it is entirely proprietary), so one does not need to dislike Microsoft to fully understand the urgent need to abandon that platform. In GitHub, there’s only one master — Microsoft — and everybody else is a slave. The issue is the_topology of coercion, not_the_words. While testing the video above I realised I had made an error near the very beginning; I meant to say this is the first part (Part 6) since Friedman had announced his impending departure; I diverged or veered into another topic and so that sentence of mine never ended. █ ⡉⢿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠀

YOU ARE HERE ☞ 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GitHub: Where everything comes to die⦈ Summary: Without giving away any spoilers or teasers, in today’s part we explain one of the more problematic things that Mr. Friedman did, likely ending his 3-year tenure and even ending his whole professional career because of Hubris, stupidity, and insensitivity towards women’s issues THE last part, Part IV, dealt with one among many GitHub scandals. Days later GitHub's_CEO_“resigned” (most likely pushed out with a couple of week’s notice). We shall show later in the series that Microsoft had many reasons to dissociate from him as soon as possible, for the same reasons it distanced itself from Bill Gates last year. They’d rather say, “he no longer works for us…” (or, “we already took the appropriate action”) “We’ll leave all the pertinent details aside until (much) later parts because we’d rather focus on legal and technical issues first.”In today’s part we turn our attention to something we did not plan last week. We sort of leap forward a bit and give a glimpse/preview into what likely led to the downfall of Mr. Friedman, who hired a friend of his from Team Mono. We’ll leave all the pertinent details aside until (much) later parts because we’d rather focus on legal and technical issues first. Those who read our IRC_logs meticulously likely know already that, in the words of one source, “Nat [Friedman] hired a domestic abuser to run Copilot and Codespaces [...] knowingly [and] he’s his best friend and has a widespread reputation for abusing women, sometimes men at work [...] worked at the original Xamarin [...] that’s part of how Nat got the job” (at Microsoft) The source said “it seemed the point of your article that I came across was the concentration of power through strangling open source [...] my questions is should we putting this power in the hands of someone is historically abusive to women?” “We’re quite certain that this is one among several contributing factors attributable to the exit of Mr. Friedman, effective next week.”“Miguel de Icaza is more sympathetic to my situation and has been quite open about the character of Nat and Alex, but does not want to speak out publicly,” the source added. “I don’t know what your sympathies are towards feminist causes, but to me this situation speaks volumes to the characters at the helm of Github’s future.” As we noted here last_year, Tom Preston-Werner (co-founder of GitHub) left GitHub after harassment connected to his partner, so there’s a bit of a theme here. We’re quite certain that this is one among several contributing factors attributable to the exit of Mr. Friedman, effective next week. In the next part (scheduled for publication on Friedman’s last day) we’ll look at various other scandals and eventually we’ll get around to some of the gory details associated with Copilot, an enabler of GPL violations on a massive scale. █ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣠⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⣦⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣼⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣸⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣧⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⡀⣠⣤⣄⣀⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠙⠻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣂⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⣤⣤⣤⣤⣀⡀⠀⠀⠀⠘⠛⠓⠐⠿⠿⣿⣷⣶⣦⣤⣤⣤⠀⠀⣤⣄⠤⢄⣀⡄⠈⢻⣿⣿⠋⢁⣀⣀⣽⡏⢙⣿⠛⢻⣿⠉⢹⣯⡄⠀⣠⣤⣤⣤⣤⡄⠀⣠⣤⣤⣤⣤⣤⣤⣤⣀⣀⣀⣀⡀⠀⠀⠀⠀⠀⠀⠀⠀ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡏⠀⢰⣿⣿⣿⣿⣿⣷⠀⠈⣿⡇⠀⣾⡟⠛⢻⡏⠉⣏⠀⢈⣹⡀⠘⠛⠃⠀⡏⠉⣿⡏⠉⡇⠀⣉⡉⠹⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣧⠀⠘⢿⣿⣿⣿⣿⠟⠀⢰⣿⣧⠀⢿⣷⡆⢸⡇⠀⣿⠀⢸⣿⠂⢸⣿⡇⠀⡗⠀⣿⡇⠀⡇⠀⣿⡇⠀⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣦⡙⠦⢼⣿⣿⠀⠀⣠⣿⣿⣿⣶⣤⣤⣤⣼⣧⣤⣿⣦⣤⣼⣤⣼⣿⣧⣤⣿⣤⣤⣤⣤⣧⣤⣤⣤⣴⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⡟⢿⣟⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣶⣾⣿⣿⣶⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠿⢿⡿⣿⣿⣿⣿⣿⣿⠿⠿⢿⣿⣿⡿⠿⡿ ⠷⣿⣷⣷⣯⣄⣍⠻⣿⣿⣿⣯⣽⡽⢿⣿⣿⣿⣿⡿⡿⢿⣿⣟⠛⠻⢿⢿⣿⣿⢿⣿⣿⣿⣿⢿⣿⣿⣿⣿⣿⣿⣿⢿⣿⢿⣿⣿⣿⣿⣿⠿⣿⣿⣿⣿⣿⣛⣿⣟⣿⣿⣷⣶⢶⣿⣿⣿⣷⣷⣬⣵⣶⣷⣴⣲⣆⣌ ⠞⢅⣵⣒⣾⣬⠺⡟⣿⣾⣿⡯⣷⣽⣗⣿⣗⣝⣿⣯⣮⣿⡞⣿⢭⣓⣿⣏⡿⡈⣿⢿⢷⣿⠏⣿⢿⣿⣻⡿⣽⣿⣿⢯⣿⣿⣫⣿⣟⣯⣿⣿⢻⡿⢷⣿⣿⣿⣟⢹⣟⢻⢿⡯⣿⣿⢻⣯⣻⣿⣿⢿⠿⠙⠯⠿⠿⠛ ⠋⠃⠀⠈⠚⡁⠓⠱⠿⠆⠘⠛⠑⠮⠿⠡⠿⠹⣿⡧⣪⠿⠡⠿⣭⣏⣿⣭⣿⣤⣿⣤⣆⣼⣠⠿⣬⣆⠫⠿⠷⠸⢿⣶⣶⣿⣌⠷⣯⠿⢿⠖⠼⢧⠶⣿⡄⣼⣧⣼⣧⡼⣴⡿⢇⡝⢧⠼⠫⠏⠍⠛⢻⡂⠄⡀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠁⠀⢀⡀⣀⣀⣀⠀⢀⣀⡀⠀⠀⠀⠀⣴⠒⣲⢨⡖⠺⣍⢻⣿⠩⣵⡟⢻⡟⡻⣻⣷⡺⡙⠲⠖⢺⣞⢏⡷⠒⣮⢳⣄⣲⡞⢲⡌⣲⣖⢲⡖⣲⣄⠉⠌⠉⠁⠁⠒⣁⠀⠀⠀⠄⠀⠀⠈⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢃⠀⠀⠈⠀⠐⠀⠀⠈⢿⣩⡢⡸⣇⣢⡟⣸⡘⠟⣸⣇⣸⣏⣅⣠⣉⣻⠆⠈⠐⣸⡟⢘⣯⣖⡿⠀⠋⣹⣏⣹⠇⣸⡏⣸⣏⣫⠀⠀⠀⠈⠀⠉⠁⠐⠒⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠴⠤⠴⠆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠐⠒⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⢀⣴⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⢸⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⢿⣿⣿⣿⣿⣿⣿⣿⣿⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⢸⣿⣿⣿⣿⣿⣷⣿⣿⣿⣿⣿⣿⣿⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣿⣿⣿⣿⣿⣿⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⢀⣾⠿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠋⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ䷩ 𝚕𝚒𝚗𝚎 1271 ╒═══════════════════ 𝐀𝐑𝐓𝐈𝐂𝐋𝐄 ═════════════════════════════════════════════════╕ (ℹ) Images, hyperlinks and comments at http://techrights.org/2021/11/08/matthew-gafam-hypocrisy/#comments Gemini version at gemini://gemini.techrights.org/2021/11/08/matthew-gafam-hypocrisy/ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 11.08.21⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Corporate_Troll_Matthew_“GAFAM”_Garrett_Complains_About_Computer_Devices Called_“Master/Slave”_While_Using_Slave_Labor⠀✐ Posted in Deception at 3:13 am by Guest Editorial Team Guest post by Ryan, reprinted with permission from the_original 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Slave_labour⦈_ According to a Doordash driver on TikTok… The way this normally happens, I’m told, is that if you don’t tip your driver, then your food sits there while driver after driver declines it. Eventually, it goes up 50 cents per driver that declines it, and then someone takes your food and brings it to you, after_about_an_hour. Of course, Garrett is the corporate troll that implemented a scheme where Microsoft has to sign off on your bootloader or else your OS won’t boot on a PC, which he calls security. But he’s also a self-proclaimed “Social Justice Warrior” always calling for people to be cancelled, and just generally whining and complaining. He’s one of the fake complainers about calling computer devices “master and slave”. Apparently, they didn’t pay him enough to leave a tip for his Doordash slave driver. You know, 1099 workers, mostly minorities, making less than minimum wage, paying double social taxes to the IRS, no health insurance, have to have their kids in the car with them in Chicago during a carjacking spree….. Slavery! He had to be muted on Techrights IRC because he kept direct messaging people, including me, to talk about sex in bizarre contexts. Unfortunately, in some circles, people don’t know what a clown this guy is, and why they should laugh at him. █ ⠀⠀⢀⣀⣤⣀⠀⠀⢠⣠⣀⣤⣄⣀⣀⣀⣠⣄⣀⣀⣀⣤⠀⣠⣄⣀⣄⣠⣤⡄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⡄⣀⣀⠠⣠⠄⠀

Meanwhile,_at_Mozilla,_You_Have_to_Sign_Into_Microsoft_to_Use_BugZilla…⠀✐ Posted in Microsoft at 3:56 pm by Guest Editorial Team Guest post by Ryan, reprinted with permission from the_original 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Mozilla_in_GitHub⦈_ Mitchell Baker strikes again… I keep saying that Mozilla is a useless thrall of Microsoft and Google, and they keep proving me right. There’s no point in using Firefox now that it has the malicious keylogger (“Suggest”) or the other spammy and scummy crap in it. I figured it was only a matter of time before they moved bug reporting to Microsoft GitHub, but in the meantime, they force you to sign in with it to use BugZilla. I think we all know where this is going. Hosting your project on GitHub, as opposed to avoiding it -or- only using it as a mirror, is already a strike against your program. Maybe Microsoft won’t just silently disappear something as visible as Firefox like they do anyone else’s project. But the fact is, that Mozilla is ignoring that they do this routinely to other people, and that their pals at Microsoft support Trump and have ICE contracts, including an ICE contract with GitHub. So much for being a company that cares about “social justice”. Matthew Garrett also loves GitHub. The truth is that he actually cares nothing about social justice, just like Mozilla doesn’t. They only use it as a wedge issue to troll actual Free Software developers. In reality, they actively support government surveillance, ICE, Trump, and slave labor. Only a person with all of the moral fiber of Jack the Ripper would look closely at what Microsoft, GitHub, and Doordash/gig economy apps do and then go ahead and hang around them anyway, do business with them. █ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣀⣀⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Video_download_link | md5sum 5d31e60d64b3c31a3c60838dd839d277 http://techrights.org/videos/software-patents-in-the-news.webm Summary: The video above shows the awful state of affairs when it comes to journalism on the subject of patents, and on software patents in particular (the_same_is_true_for_"Linux",_as_we_explained_and_showed_last_week) The software patents conundrum is hardly new to me; I’ve written about it for nearly two decades and over the past 5-10 years anything resembling journalism on the subject of software patents diminished to zero; there’s just about a sum total of zero articles on this subject, at least in English (law firms doing shameless self-promotion of software patents doesn’t count as journalism). The subject or this issue isn’t particularly new; over the past half a decade we’ve repeatedly complained about how “the news” was basically dominated by those looking to profit from patent litigation. █ ䷩ 𝚕𝚒𝚗𝚎 3252 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 11.08.21⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Links_8/11/2021:_Guile-CV_0.3.0,_Intel_DRM_Chaos⠀✐ Posted in News_Roundup at 6:14 am by Dr. Roy Schestowitz 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GNOME bluefish⦈ § Contents⠀➾ * GNU/Linux o Distributions o Devices/Embedded * Free_Software/Open_Source * Leftovers * § GNU/Linux⠀➾ o § Desktop/Laptop⠀➾ # ⚓ Linux_Weekly_Roundup_#155⠀⇛ I hope you are doing well! We had another wonderful week in the world of Linux releases with Fedora 35, Voyager Live 21.10, Freespire 8.0 Beta 1, and PCLinuxOS 2021.11. # ⚓ 9to5Linux_Weekly_Roundup:_November_7th,_2021⠀⇛ This week has been great for fans of the Fedora Linux distribution (yes, that includes me) and the GNOME desktop environment (that also includes me) as we saw the release of Fedora Linux 35 with the latest GNOME 41.1 desktop environment, and GNOME 40 folks were also updated to the 40.5 point release. But there were many awesome Linux news this week, starting with the release of the LXQt 1.0 desktop environment and Mozilla Firefox 94 web browser, and continuing with the GNU Linux-libre 5.15 kernel, LibreOffice 7.1.7 office suite, and HPLIP 3.21.10 printer/scanner drivers. # ⚓ System76_Engineer_Confirms_Work_on_New_Rust-Written Desktop,_Not_Based_on_GNOME⠀⇛ In other comments Murphy clarified that essentially the gist of it would be an independent/distro- agnostic desktop environment, and that they’d be “using tooling that already exists (mutter, kwin, wlroots), but implementing the surrounding shell in Rust from scratch…” And he added later that “We already do our best to follow freedesktop specifications with our software. So there’s no reason to think we’d do otherwise.” o § Audiocasts/Shows⠀➾ # ⚓ Linux_Action_News_214⠀⇛ Significant changes at GitHub, Ubuntu starts work on a new desktop tool, why WirePlumber is a big deal, and we bust some Red Hat FUD. # ⚓ Josh_Bressers:_Episode_296_–_Is_Trojan_Source_a vulnerability?⠀⇛ Josh and Kurt talk about the new Trojan Source bug. We don’t always agree on if this is a vulnerability (it’s not), but by the end we come to an agreement that ASCII is out, Unicode is in. We don’t live in a world where you can make a realistic suggestion to return to using only ASCII. There are a lot of weird moving parts with this one. o § Benchmarks⠀➾ # ⚓ Intel_Core_i9_12900K_“Alder_Lake”_AVX-512_On_Linux⠀⇛ While it was initially communicated by Intel that Alder Lake’s Golden Cove P-Cores has AVX-512 “fused off”, that has turned out not to be the case at least with the initial batch of processors and current BIOS/firmware configurations. If disabling the power-efficient Gracemont E-Cores, it’s possible to enable AVX-512 and make use of it. Here are some initial AVX-512 benchmarks in such a configuration under Linux with the Core i9 12900K. # ⚓ ODROID-N2+_review_with_Ubuntu_21.10_using_Wayland_and Panfrost⠀⇛ ODROID-N2+ was launched in July 2020, but I only got the Amlogic S922X Rev C SBC recently with Hardkernel wanting me to test their latest Ubuntu 21.10 image with the Panfrost open-source GPU driver. [...] In summary, ODROID-N2+ is fast for an Arm platform. For perfectly smooth video playback in YouTube better use 720p at this time. Firefox uses H.264 video decoding limited to 1080p, while Chromium supports up to 4K using VP9, but it’s unwatchable. The WebGL aquarium demo renders at 16-17 fps in Firefox with 500 fish, but only 3 fps in Chromium, probably because GPU acceleration is not supported/ enabled? SuperTuxKart plays OK in full-screen mode, but it’s not as smooth as I would like. I tried Super Mario Sunshine in the Dolphin emulator, and it worked very well. I had an issue with white text on white background in the Dolphin emulator, and the workaround was to switch to the dark theme in Ubuntu’s Appearance Settings. o § Applications⠀➾ # ⚓ 7_Free_and_Open_Source_Plotting_Tools_[For_Maths_and Stats]⠀⇛ We live in a world where almost everything we have generates data. Data, which can be analyzed and visualized thanks to tools that create graphs showing the relation between variables. These tools are famously called “plotting apps”. They can be used for basic maths task in school to professional scientific projects. They can also be used for adding stats and data to presentations. There are plenty of free and open source plotting apps available for Linux. But in this article, I am listing some of the best plotting apps I have come across. o § Instructionals/Technical⠀➾ # ⚓ How_to_Installl_OpenShift_4.9_on_Bare_Metal_(UPI)⠀⇛ Hello Techies, as you know Openshift provides container platform and can installed on onprem or in public cloud using different methods like IPI (Installer Provisioned Installer), UPI (User Provisioned Infrastructure) and Assisted Bare Metal installer. In this post, we will demonstrate how to install Openshift 4.9 on bare metal nodes with UPI approach. For the demonstration purpose, I am using KVM virtual machines. Following are my lab setup details, Total Virtual Machines: 7 # ⚓ How_to_Configure_Jenkins_with_SSL_Behind_Nginx_on_Ubuntu 20.04⠀⇛ Jenkins is an open-source tool automation tool to set up the entire software delivery pipeline - continuous delivery. This enables developers to manage and control software delivery processes throughout the entire lifecycle such as to reliably build, test, and deploy their software. Jenkins has an extensible and vibrant, active community. It is written in Java. Generally, Jenkins runs as a standalone built-in Java servlet application. It is also possible to run in Java servlet containers such as Apache Tomcat or GlassFish. In this tutorial, we learn how to configure Jenkins with SSL behind Nginx on Ubuntu 20.04. # ⚓ Install_and_configure_OwnCloud_on_Ubuntu_21_/_Debian_11_– Unixcop_the_Unix_/_Linux_the_admins_deams⠀⇛ OwnCloud is a self-hosted file sync and share server. It provides access to your data through a web interface, sync clients or WebDAV while providing a platform to view, sync and share across devices easily—all under your control. OwnCloud’s open architecture is extensible via a simple but powerful API for applications and plugins and it works with any storage. # ⚓ Install_ClamAV_Antivirus_in_Debian_11_Bullseye_and_Ubuntu 20.04_–_LinuxStoney⠀⇛ ClamAV is an open-source Antivirus tool available for Linux distributions. It integrates Mail servers to scan attachments received. In addition to scanning mail attachments, it provides protection to corporate networks. Other functions also include web scanning. In this article, we would discuss how to install ClamAV Antivirus in Debian 11 Bullseye and Ubuntu 20.04. # ⚓ How_to_setup_Network_after_Rocky_Linux_8_/_CentOS_8_minimal installation_–_LinuxStoney⠀⇛ After installing Rocky Linux 8/ AlmaLinux 8 / RHEL / CentOS 7 minimal, You may not able to connect network in that machine. This will happen because Ethernet interfaces are not enabled by default. This guide explain you to setup network on Rocky Linux 8 / AlmaLinux 8 / RHEL/CentOS 7. # ⚓ How_to_Solve_Missing_Kernel_Headers_Issue_on_Rocky_Linux_8 /_CentOS_8_–_LinuxStoney⠀⇛ You may face some problem on your Rocky Linux 8 and CentOS 8 machine when running cloud server inside it. Like the issues we have found recently, where my Rocky Linux 8 / CentOS 8 machine facing missing Linux kernel-headers issue. Well, on this today guide I will show you on how to solve that issues. This very easy to solve the issue, so simply take your time for moments to fix the issue. # ⚓ Installing_NextCloud_«_etbe_–_Russell_Coker⠀⇛ Some time ago I tried OwnCloud, it wasn’t a positive experience for me. Since that time I’ve got a server with a much faster CPU, a faster Internet connection, and the NextCloud code is newer and running on a newer version of PHP, I didn’t make good notes so I’m not sure which factors were most responsible for having a better experience this time. According to the NextCloud Wikipedia page [1] the fork of NextCloud from the OpenCloud base happened in 2016 so it’s obviously been a while since I tried it, it was probably long before 2016. # ⚓ Live_Debugging_Techniques_for_the_Linux_Kernel,_Part_1_of 3⠀⇛ # ⚓ List_Open_Files_On_Linux_With_The_Lsof_Command_– Invidious⠀⇛ Sometimes processes running on Linux will lock down files and today we’re going to look at a program that’ll help you identify which programs are doing that and which files are locked, this is lsof # ⚓ How_to_enable_Function_Keys_on_a_Chromebook⠀⇛ Today we are looking at how to enable Function Keys on a Chromebook Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below. # ⚓ How_to_install_the_Opera_Browser_on_Elementary_OS_6.0_– Invidious⠀⇛ In this video, we are looking at how to install the Opera Browser on Elementary OS 6.0. # ⚓ How_To_Install_Blue_Recorder_on_Ubuntu_20.04_LTS_–_idroot⠀⇛ In this tutorial, we will show you how to install Blue Recorder on Ubuntu 20.04 LTS. For those of you who didn’t know, Blue Recorder is a simple desktop recorder for Linux systems. It is released under open-source GNU General Public License version 3 and built using Rust, GTK+ 3, and FFmpeg. You can record video in Mkv, Avi, mp4, WMV, gif, and nut file formats. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Blue Recorder screen recorder on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint. o § Distributions⠀➾ # § Reviews⠀➾ # ⚓ Review:_MX_Linux_21⠀⇛ There is no reason why MX Linux 21, the newest version of yet another of Linux’s seemingly infinite number of community-based operating systems, should be this well done. This is, after all, a mostly volunteer operation, just like all the other of Linux’s seemingly infinite number of community-based operating systems. But it is that well done. That MX 21, codenamed Wildflower, is such a joy to use speaks volumes about Linux and its potential on the desktop, the dedication of its users, and why so many of us never want to boot a Big Tech operating system ever again. It’s not so much that MX 21 just works, but that its developers have made a serious effort to identify what would make it work even better. # § PCLinuxOS/Mageia/Mandriva/OpenMandriva Family⠀➾ # ⚓ Kernel_Updates_Available⠀⇛ The following kernels are available for PCLinuxOS. Kernel LTS 5.4.158. Kernel LTS 5.10.78 and Kernel 5.14.17. # § SUSE/OpenSUSE⠀➾ # ⚓ Preparing_for_the_new_needs_of_edge_computing [Ed: SUSE prepares for buzzwords, not substance. SUSE is also shilling the frauds_and_charlatans_from_Gartner Group.]⠀⇛ # § Debian Family⠀➾ # ⚓ Eagle’s_Path:_Modifying_the_Debian_resolution_process (2021-11-07)⠀⇛ I have been working on a draft GR to modify the process used by the Technical Committee and for General Resolutions to prepare a ballot for vote, with a goal of fixing several issues that were uncovered by recent votes. My plan is to propose this formally as a GR on November 13th. For those reading my journal who are Debian Developers or who are interested in Debian process, you may want to read the draft resolution and the previous discussion. Constitutional changes require a 3: 1 majority, so my goal is to reach as broad of a consensus in the project on these changes as possible. All feedback welcome, and also let me know if there is a reason to postpone making this a formal GR and thus starting the discussion period clock. o § Devices/Embedded⠀➾ # ⚓ Halloween_Hack_Requires_Minimum_Code,_Produces_Maximum_Fun |_Hackaday⠀⇛ Rather than take the electronics-only route, which would undoubtedly include a few 555 timers and some other classics, [Conor] elected to stick with higher-level embedded boards, including fan- favorites such as an ESP32 and a Raspberry Pi, while still trying to keep code to a minimum. Thanks to the visual languages Espruino Blockly and NODE-RED, he only needed to write a couple lines of “traditional code,” as he calls it: a simple JavaScript HTTP request. The project itself consisted of an ultrasonic sensor hooked up to an ESP32, which would detect when children approached the door. The ESP32 used Espruino visual scripting to notify a Raspberry Pi when it sensed motion. The Raspberry Pi would play some spooky sounds, and coordinate with some old conference badges to turn on some lights and trigger a fog machine. The Pi also used a service called Tines to send a door notification via Telegram. o § Free, Libre, and Open Source Software⠀➾ # § Web Browsers⠀➾ # § Mozilla⠀➾ # ⚓ LibreWolf_94_is_a_Firefox_variant_with_a_focus on_privacy_and_security⠀⇛ The LibreWolf 94 web browser is available , which is a rebuild of Firefox 94 with changes to improve security and privacy. The project is being developed by a community of enthusiasts. Changes are published under the MPL 2.0 license (Mozilla Public License). Builds are generated for Linux (Debian, Fedora, Gentoo, Ubuntu, Arch, Flatpak, AppImage), macOS and Windows. # § FSF⠀➾ # § GNU Projects⠀➾ # ⚓ Guile-CV_version_0.3.0⠀⇛ This is a maintenance release, which allows Guile-CV to work with Guile 3.0 (>= 3.0.7 to be specific). In addition, im-transpose performance has been improved. The documentation has been restructured and follows the model we adopted for GNU G-Golf. The Configuring Guile’s raised exception system section has been updated. Make sure you carefully read and apply the proposed changes. * § Leftovers⠀➾ o ⚓ In_the_Heart_of_the_Gorge⠀⇛ Cape Horn stands at the mouth of the Columbia Gorge, the last large cliff on the north side of the 100-mile-long chasm the great river of the Northwest carved through the Cascade Range, as it barreled its way toward Cape Disappointment, the Desdemona Straits, and the Pacific Ocean another 120 river miles to the West. Cape Horn is made of basalt, laid down by successive floods of lava pouring out of volcanic fissures in the earth on the Idaho/Oregon border more than five million years ago.

All in the name of protecting her freedoms to spread deadly germs to others. # ⚓ After_drinking_water_crisis,_Newark_is_winning_war_on lead⠀⇛ The water service line was one of more than 20,000 made with the toxic metal the city began replacing in 2019 amid public outrage over revelations about high lead levels in the tap water in schools and homes across the city. Less than three years after the work began, the replacement project, initially projected to take up to 10 years, is nearly complete. o § Integrity/Availability⠀➾ # § Proprietary⠀➾ # § Security⠀➾ # ⚓ Nessus_10_is_out,_with_Raspberry_Pi_support_– Help_Net_Security⠀⇛ Tenable has released Nessus 10 and extended supported platforms to include Raspberry Pi, allowing penetration testers, consultants, security teams and students to deploy the power of Nessus anywhere. # ⚓ Reproducible_Builds:_Reproducible_Builds_in October_2021⠀⇛ Welcome to the October 2021 report from the Reproducible Builds project! This month Samanta Navarro posted to the oss-security security mailing on a novel category of exploit in the .tar archive format, where a single .tar file contains different contents depending on the tar utility being used. # § Privacy/Surveillance⠀➾ # ⚓ Microsoft_says_it_will_end_OneDrive updates_to_Windows_7_and_8_in_March⠀⇛ Microsoft says OneDrive users on Windows, 7, 8, or 8.1 will be unable to sync their content to the cloud starting on March 1st, 2022, according to a blog post on its Tech Community forum. OneDrive will also no longer receive updates if it’s running on a system that doesn’t have Windows 10 or Windows 11 installed. o § Defence/Aggression⠀➾ # ⚓ Iraqi_President_Slams_Assassination_Attempt_against_PM, Warns_of_Coup_against_Constitution⠀⇛ Iraqi President Barham Salih condemned on Sunday the failed assassination attempt against Prime Minister Mustafa al-Kadhimi. # ⚓ Students_Are_Pushing_US_Colleges_to_Sever_Ties_With Military-Industrial_Complex⠀⇛ o § Environment⠀➾ # ⚓ Lights_Out:_5_New_‘Dark-Sky_Places’_for_Top-Shelf Stargazing⠀⇛ To help reduce light pollution — obtrusive artificial light that obscures views of the stars and planets — the group suggests simple changes, such as angling exterior lights downward to limit the disturbance to nocturnal wildlife. “Each dark-sky place acts as an important vehicle to bring messages about the importance of dark skies and quality outdoor lighting to a wider audience, most notably people who live in cities,” Ms. Wilson said in an email. All protected public lands as well as private ones that provide nighttime access are eligible for the certification. # ⚓ This_Is_What_Africa_Needs_Right_Now⠀⇛ How do you tell people that they must leave their community or drown? This was the gut-wrenching decision I faced five years ago, as president of Liberia, when thousands of families in the capital’s largest township saw their homes swept out to sea. # ⚓ UV_radiation_is_broiling_Bolivia’s_highlands_–_CNN⠀⇛ Bolivia’s highlands city of La Paz has been hit by an unusual heatwave, with levels of ultraviolet (UV) radiation soaring off the charts, exacerbated by unusually low levels of cloud cover some experts link to climate change. Levels of UV radiation have at times in recent weeks hit 21 on a scale that normally only goes up as far as 20. According to the World Health Organization, a UV index of 11 is regarded as “extreme,” with people cautioned to avoid exposure to the sun. “The sun is burning. This sun isn’t normal,” said La Paz resident Segundina Mamani, as people in the city at 3,600 meters (11,800 feet) above sea level tried to keep cool by eating shaved ice and keeping to the shadows. # ⚓ New_report_shows_that_10_Facebook_pages_are_responsible_for 69%_of_climate_denial_posts⠀⇛ A new report from the Center For Countering Digital Hate analyzed nearly 7,000 top-performing climate denial Facebook posts from the last year, and found that 69% of them came from the same 10 pages… # ⚓ 2021_Was_Terrible_for_North_American_Glaciers._COP26_May Seal_Their_Fate.⠀⇛ # ⚓ Climate_Grief_Hurts_Because_It’s_Supposed_To⠀⇛ This column is part of Covering Climate Now, a global journalism collaboration cofounded by Columbia Journalism Review and The Nation to strengthen coverage of the climate story. # § Energy⠀➾ # ⚓ Opinion_|_Keep_Fossil_Fuels_in_the_Ground._Everything Else_Is_Just_Talk⠀⇛ In some respects, preventing climate breakdown is highly complicated. But in another, it’s really simple: we need to leave fossil fuels in the ground. All the bluster and grandstanding, the extravagant promises and detailed mechanisms discussed in Glasgow this week amount to nothing if this simple and obvious thing doesn’t happen. # ⚓ Maine_Voters_and_Foreign_Companies_Squared_Off_Over Energy_Corridor._Voters_Won.⠀⇛ # ⚓ Arctic_Exploits⠀⇛ Zinke had already made it clear that Alaska was central to the administration’s “energy dominance” agenda. One of his first trips as Interior Secretary was to Denali and then Anchorage where he delivered a speech at the Alaska Oil and Gas Association’s annual conference, assuring industry executives that the path to energy dominance would run through the great state of Alaska and the North Slope in particular. He formed a fast friendship with Alaska’s senior senator, Lisa Murkowski. Her former campaign chairman, Steve Wackowski, a brash 39-year-old with no experience in public lands management, was appointed senior advisor for Alaska Affairs. Former staffers for Rep. Don Young and Senator Dan Sullivan would also get plum positions at DOI. David Bernhardt, who had once defended the state of Alaska against the FWS in an effort to open the refuge to seismic exploration, would eventually take over as Secretary. # ⚓ Bitcoin,_Ethereum_Mining_Threatens_Paris_Climate Agreement:_Swedish_Financial_Regulator⠀⇛ Sweden’s financial supervisory authority, Finansinspektionen, has called for a ban on crypto mining, calling cryptocurrencies a threat to the climate. Cryptocurrency mining requires immense amounts of electricity, and as a result, some crypto miners have pivoted to renewable energy sources amid growing criticism. Crucially, however, that poses an additional problem for Sweden. o § Finance⠀➾ # ⚓ Opinion_|_The_Cruelest_Form_of_Capitalism_in_the_World⠀⇛ Elon Musk’s wealth has surpassed $200 billion. It would take the median U.S. worker over 4 million years to make that much. # ⚓ The_US_Owes_Mexico_at_Least_$37_Trillion_in_Reparations_for Poverty,_Violence,_and_Environmental_Damage⠀⇛ Following the Trump years, the new Biden administration says it is trying to establish a better relationship with Mexico, through “cooperation.” Early in October, the US and Mexico began discussing a new joint security plan. “After 13 years of the Merida Initiative, it’s time for a comprehensive new approach to our security cooperation, one that will see us as equal partners in defining our shared priorities,” US Secretary of State Antony Blinken said. The joint statement on the security dialogue was also pretentious spin; “As two nations with an enduring partnership based on sovereignty, mutual respect, and the extraordinary bond of family and friendship … we each recognize our shared responsibility and pledge to move forward as partners to find solutions that are backed by justice…” # ⚓ The_COVID_Supply_Chain_Breakdown_Can_Be_Traced_to Capitalist_Globalization⠀⇛ o § AstroTurf/Lobbying/Politics⠀➾ # ⚓ Opinion_|_Latin_America_Needs_a_Progressive_Green Democratic_Revolution⠀⇛ With the climate crisis emerging as the next great challenge, many progressive leaders in advanced economies have advocated for a Green New Deal, which would shift economic policy and redistribute wealth. In the Global South, however, the centrality of a green transformation is still contested. Some argue that these countries should focus on pressing social issues such as poverty, housing or healthcare before facing the climate crisis, while others believe that the climate movement can simply be appeased with limited policy commitments. # ⚓ Opinion_|_Media’s_False_Election_Lesson:_‘Ambitious’_Dems Must_Move_to_the_Right⠀⇛ # ⚓ To_win,_Democrats_need_to_end_the_backroom_dealing⠀⇛ The Democratic Party’s legislation in Congress is being whittled away to small-bore spending here and there, totaling far less than one percent of America’s GDP. The corporate lobbies have been waging a relentless and largely successful battle against higher taxes on the corporations and the rich, even though the public supports increasing taxation on the wealthy to expand public spending on higher education, health care, families and the environment. # ⚓ University_of_Florida_reverses_decision,_will_allow professors_to_testify_as_paid_experts_in_voting_rights_case⠀⇛ The University of Florida on Friday announced that it will now allow three professors to testify as paid experts in a voting rights lawsuit, reversing its previous decision. In an email sent to the campus community on Friday, university President Kent Fuchs explained that he is asking the University’s Conflicts of Interest Office to reverse the decisions on recent requests by UF employees to serve as expert witnesses in litigation in which the state of Florida is a party and to approve the requests regardless of personal compensation. # ⚓ Groups_Rally_in_Albany_as_Part_of_Global_Call_for_Climate Justice_at_COP26⠀⇛ 200 people from across the Capital District joined a demonstration for climate justice today in Albany. The march and rally were part of a global day of action coinciding with the COP26 UN global climate summit taking place in Glasgow. World leaders are meeting in Glasgow through November 12 to negotiate stronger climate actions than agreed to in the Paris Climate Accords in 2015. Speakers highlighted the urgent need for a fast and fair global transition to a climate friendly economy. (Some photos ) The global day of action has been organized by the COP26 Coalition which said: “Global problems need global solutions. The decisions made at COP26 will shape how governments respond (or not) to the climate crisis. So far, governments have done too little too late, proposing steps that fail to match the scale of the problem. COP26 is happening at a crucial moment in history. Across the world and across movements, we are seeing a new wave of people standing up and making their voices heard through global solidarity and grassroots organizing. We have a unique opportunity to rewire our system as we recover from the global pandemic.” o § Censorship/Free Speech⠀➾ # ⚓ Opinion_|_Attacks_on_Professors_Are_Attacks_on_Democracy⠀⇛ On Tuesday, J.D. Vance, author of the bestselling Hillbilly Elegy and now candidate for the U.S. Senate from Ohio, gave a keynote speech at the National Conservatism Conference titled “The Universities Are the Enemy.” # ⚓ Book_on_censorship_banned_in_Singapore⠀⇛ Singapore has banned a book on censorship over “offensive images” including controversial cartoons of the Muslim Prophet Mohammed, authorities said. The city-state is majority ethnic Chinese but has a sizeable Muslim minority, and has strict laws to curb hate speech and actions promoting ill-will between religious or racial groups. The book, “Red Lines: Political Cartoons and the Struggle Against Censorship” is banned from distribution in Singapore, the Infocomm Media Development Authority (IMDA) said on Monday. o § Civil Rights/Policing⠀➾ # ⚓ Schools_That_Ban_Symbols_of_Antiracism_From_the_Classroom Are_Normalizing_Racism⠀⇛ # ⚓ Opinion_|_Virginia’s_Long_History_of_Racism_Reared_Its_Ugly Head_in_the_Youngkin_Victory⠀⇛ It’s as if the last 400 years did not occur. # ⚓ How_Police_Justify_Killing_Drivers:_The_Vehicle_Was_a Weapon⠀⇛ But in many instances, local police officers, state troopers and sheriff’s deputies put themselves at risk by jumping in front of moving cars, then aiming their guns at the drivers as if in a Hollywood movie, according to body-camera footage. Or they reached into cars and became entangled with motorists, then opened fire. Often, the drivers were trying to get away from officers, edging around them, not toward them, the footage shows, and the officers weren’t in the path of the vehicle when they fired. “You see many where bullets are in the back of the car, in the side of the car,” said Geoffrey Alpert, a criminologist at the University of South Carolina who has researched high-risk police activities for more than 30 years. “In the high 90 percentile of cases I’ve seen, the person’s just trying to get away.” # ⚓ Parents_of_270_children_separated_at_border_under_Trump have_still_not_been_found,_court_filing_says_–_CNNPolitics⠀⇛ Attorneys are still trying to reach the parents of 270 migrant children who were separated at the US- Mexico border under the Trump administration, down from 303 in September, according to a federal court filing Wednesday. The filing from the Justice Department and the American Civil Liberties Union is part of an effort to identify and reunite families three years after the so-called zero-tolerance policy was created. # ⚓ Airlines_keep_losing_and_damaging_wheelchairs_at_an alarming_rate⠀⇛ o § Digital Restrictions (DRM)⠀➾ # ⚓ Intel_is_shutting_down_DirectX_12_support_for_some_older processors⠀⇛ Tom’s Hardware spotted the update, which states that DirectX 12 support will end for the affected CPU/GPU combos starting with Intel graphics driver version 15.40.44.5107. The affected processor lines and their integrated graphics pairings debuted in 2013, generally coming off the market the following year, though desktops and laptops with those CPUs may have been sold for several more. For a sense of perspective, most of these machines would have been sold running Windows 8, like the Lenovo G50-45 above. # ⚓ Intel_Disables_DirectX_12_for_Some_CPUs_Due_to_Security Flaw⠀⇛ Starting from Intel’s graphics driver version 15.40.44.5107, applications that run exclusively on DirectX 12 API no longer work with GPUs integrated into Intel’s 4th Generation Core processors as well as Celeron and Pentium chips powered by the Haswell architecture. The GPUs in question are based on Intel’s Gen7 architecture. o § Monopolies⠀➾ # ⚓ Rights_owners_agree_‘realistic’_DSA_compromise [Ed: They are not owners and these are not rights.

He defines primary IP rights as those that have been part of law for more than 50 years. Whereas, adding new rights to the primary rights, instead of changing them, creates secondary rights. As such, the book looks at both the need to, and the consequences of, changing primary rights, as well as whether adding secondary rights is a good idea, and if so, how and when. The book is then presented in four parts, which reflect the four key themes: reforming the fundamental aspects of IP; the impact of artificial intelligence on IP, particularly considering data; specific reforms of copyright and trade mark; and geographical names and indications. # § Patents⠀➾ # ⚓ Venue_Mandamus_Petitions_Continue_to_Flow_to_the Federal_Circuit_|_Patently-O⠀⇛ We’ve been writing a lot about venue and mandamus petitions at the Federal Circuit.

Adam Hines of HGF and Christy Lea and Sabing Lee of Knobbe Martens will compare and contrast mechanisms for challenging patents in both Europe and the U.S., and in particular, will focus on opposition proceedings before the European Patent Office (EPO) along with proceedings at the Patent Trial and Appeal Board (PTAB) in the U.S. The panel will also provide practical tips on how to maximize the chance of success in each jurisdiction. # ⚓ Patent_Law_Textbooks:_A_Micro-Symposium [Ed: Religious textbooks or holy books of patent law, making false assumptions and spreading myths for personal (financial) gain]⠀⇛ # ⚓ Optis_Puts_Apple’s_Feet_To_The_UK_Fire:_Commit_To FRAND_Or_Be_Snuffed_Out [Ed: Price-fixing_patent cartels]⠀⇛ Recent developments indicate that the UK is a favorable jurisdiction that owners of standard essential patents (“SEP”) can leverage to obtain appropriate SEP rates from what would otherwise be unwilling licensees. Demonstrating the point, a recent order from Justice Meade of the High Court in the sprawling Pan Optis/Unwired Planet SEP dispute with Apple provides an outline to the UK’s approach to handling SEP implementers who are unwilling to commit to court- determined FRAND licenses. In a lengthy decision, issued September 27, 2021, Justice Meade essentially gave Apple two choices: (1) commit, now, to taking a FRAND license with terms to be decided at a subsequent trial taking place in 2022; or (2) be enjoined from the UK market until resolution of the FRAND trial and acceptance of the terms that issue. Importantly, Justice Meade issued this ultimatum even though Apple has threatened to abandon the UK market rather than agree to any global FRAND rate set by the UK courts. # ⚓ Corner_office_podcast:_Dolby_chief_on_patent_pools and_EPO_wins [Ed: Dolby_viciously_attacks_GNU/Linux with_software_patents, but patent trolls’ operatives give them a platform]⠀⇛ Heath Hoglund, chief patent counsel at Dolby in San Francisco, sits down with Managing IP to talk about licensing, FRAND and more # ⚓ HMRC_statistics_show_an_increasing_use_of_UK’s_Patent Box,_but_many_companies_are_missing_out [Ed: In the UK, patents have become a mechanism_for_tax_evasion. For those who can afford to amass patents, i.e. the rich.]⠀⇛ HM Revenue and Customs (HMRC) has recently published annual statistics relating to the UK’s Patent Box tax relief scheme. The update covers the tax year from 2018 to 2019 and indicates that 1,405 companies claimed relief under the Patent Box, with the total value of relief claimed being £1,129 million. This shows an ever increasing value of relief claimed – the value of relief claimed has increased year on year from its introduction in tax year 2013 to 2014. However, it appears that the rate of increase has slowed. There is a time lag for reporting the statistics as companies must notify HMRC within two years after the end of the accounting period in which the relevant profits and income arise. # ⚓ Why_are_patents_important_in_a_post-COVID_world? [Ed: Talk about missing the point or deflecting. COVID-19 has demonstrated that patents needlessly kill millions of people, all for the sake of enriching very few people who got patents on work funded by taxpayers anyway.]⠀⇛ It has been almost two years since the world changed forever — when the outbreak of COVID- 19 exploded into a pandemic, and numerous aspects of society as we had known it shut down, went on hold or transformed. Understanding the full repercussions will be a near-Herculean task for future historians, but there are some things we can say now with reasonable certainty. # ⚓ Lawsuit_accuses_Rhombus_Systems_of_patent infringement⠀⇛ # ⚓ Royalty_Pharma_v_Boehringer:_The_UK’s_Patents_Court Takes_On_The_German_Law_Of_Licence_Negotiations_And_EPC 2000_Purpose-limited_Product_Claims [Ed: EPC 2000 is obsolete and irrelevant because EPO routinely_violates it_without_any_consequences_whatsoever]⠀⇛ The UK’s Patents Court has recently handed down judgment in Royalty Pharma Collection Trust v Boehringer Ingelheim GmbH1. As this case concerns German Law, we will not go into the details but it is clear that interesting points on patent licensing and substantive patent law feature extensively. Royalty Pharma sued Boehringer for about €23 million in outstanding royalties on linagliptin containing products for diabetes treatment. The claim arises from an amended agreement negotiated in 2015. Boehringer counterclaimed for an unquantified overpayment relating to the original agreement. # ⚓ Injunctions_will_remain_the_norm_in_Germany,_sources say [Ed: Unless one believes that embargo magically drives innovation, this is Germany shooting its own foot to funnel capital to some useless lawyers and trolls/parasites]⠀⇛ The demise of Germany’s automatic injunction may have been greatly exaggerated, but the proportionality test could still have a real impact # ⚓ UK_Court’s_‘Willingness’_Decision_In_Optis_v_Apple_To Be_Appealed [Ed: Patent lawyers in London are enjoying patent trolls while the rest of us suffer and pay for all this chaos]⠀⇛ Only a week after the judgment that a party who has been held to infringe a valid and essential patent must provide an irrevocable commitment to take whatever FRAND licence the court determines or accept an injunction, the UK Court sat again to hear Apple’s request for permission to appeal. The Court showed little hesitation in giving Apple permission to appeal its decision on three of the four grounds sought by Apple. The Court had already indicated in its judgment that it was minded to allow Apple to appeal, which is unsurprising given that this is a novel and important decision that could have implications for SEP licensing negotiations across the globe. Read our previous article to find out more on the original decision. # ⚓ UK:_Chinese_Courts_Confirm_Jurisdiction_To_Set_Global FRAND_Terms [Ed: Debunking this ridiculous idea that we need more and more patents or else "China will win"]⠀⇛ The court judgement for the UK Supreme Court landmark Standard Essential Patent (SEP) and global FRAND (Fair, Reasonable And Non- Discriminatory) licensing case Unwired Planet v Huawei was handed down in the Autumn of 2020 (see here for additional discussion of this decision). In the decision, the UK Supreme Court confirmed the ability of the UK courts to set terms for global FRAND licenses; at the time, the UK courts were the only courts that had determined this ability. # ⚓ European_plausibility_uncertainties_could_be_cleared up_by_new_Enlarged_Board_of_Appeal_referral [Ed: This board is rigged, but IAM is bribed by the EPO, so it will not tell you this]⠀⇛ An EPO Board of Appeal is seeking clarity on the crucial but complicated question of plausibility and has referred a case to the Enlarged Board of Appeal that may – or may not – provide the answers # ⚓ Arecor’s_polysaccharide_vaccine_patent_upheld [Ed: Instead of helping with vaccines the compromised and corrupt EPO grants monopolies on them]⠀⇛ Arecor Therapeutics plc (AIM: AREC), the biopharmaceutical group advancing today’s therapies to enable healthier lives, continues to build a strong patent portfolio protecting its proprietary Arestat™ technology.

If he is confirmed by the Senate, Stark will replace Kathleen O’Malley, who plans to retire in March 2022. O’Malley told Managing IP that she couldn’t be more pleased with the announcement. “He will bring a wealth of knowledge regarding how trial records are developed in patent cases and the challenges district courts face in those complex and contentious matters,” she said. # ⚓ Tech_and_Sourcing_News [Ed: The patent litigation firms still promote pure fiction]⠀⇛ In this edition we bring you news of the landmark ruling denying AI machines the right to be named as a patent inventor, the DTI’s plan to make the UK to make a global leader in digital trade and the outcome of the CJEU’s ruling that software can constitute goods for the purposes of the Commercial Agents Directive, amongst other tech and sourcing news. # ⚓ The_Roadmap_of_Litigation_Analytics [Ed: Imagine being so greedy and sick in the head that you start to think of ruinous litigation like a sport]⠀⇛ Litigation analytics can be considered a roadmap of sorts — an important guide to ensure the legal professional arrives at the correct litigation strategy or business plan. However, like roadmaps, litigation analytics will only be useful if it’s based on data that is complete and accurate. # ⚓ Spotlight_on_Upcoming_Oral_Arguments_–_November 2021⠀⇛ Hunting petitioned for inter partes review (“IPR”) of U.S. Patent No. 9,581,422, alleging the challenged claims were invalid as both anticipated and obvious. Following institution, DynaEnergetics filed a motion to amend the ’422 patent contingent on the Patent Trial and Appeal Board (“Board”) finding the original claims unpatentable. Hunting opposed, arguing the amended claims were obvious (but not anticipated). In its Final Written Decision, the Board found both the original and amended claims to be anticipated. DynaEnergetics sought review of the Board’s decision by the Precedential Opinion Panel (“POP”), arguing the Board improperly raised sua sponte anticipation of the amended claims. The POP granted review and agreed with DynaEnergetics. Citing Nike Inc. v. Adidas AG, the POP held that while “the Board may, in certain rare circumstances, raise a ground of unpatentability that a petitioner did not advance, or insufficiently developed, against substitute claims proposed in a motion to amend,” those circumstances were not present. The POP vacated the Board’s decision and granted DynaEnergetics’ motion to amend. Hunting appeals. [...] Unified petitioned for inter partes review of Arsus’s U.S. Patent No. 10,259,494 (“the ’494 patent”). Following institution, Arsus statutorily disclaimed the challenged claims and moved to dismiss the IPR. The Board construed Arsus’s disclaimer as a request for adverse judgment, which it granted. Arsus filed a “Demand” that the Board vacate the adverse judgment, arguing the disclaimer deprived the Board of subject matter jurisdiction over the IPR. The Board declined to vacate its adverse judgment. Arsus appeals. Arsus argues the Federal Circuit held in Sanofi-Aventis U.S., LLC v. Dr. Reddy’s Labs., Inc. that, following a statutory disclaimer, the disclaimed claims are “effectively eliminated” and it is “as though the disclaimed claim(s) had never existed,” which “moot[s]” a case or controversy. Under Sanofi, it argues, the Board should have acted as if its disclaimed claims never existed and dismissed the IPR. Arsus also highlights Facebook, Inc. v. Skky, LLC, where it argues the Board declined to exercise jurisdiction over disclaimed claims. Unified and the USPTO respond that 37 C.F.R. § 42.73(b) explicitly provides for disclaimer as a request for adverse judgment. They argue Sanofi concerned the Article III case or controversy requirement, which does not apply to agency proceedings, such as IPRs. # ⚓ PTAB’s_Structure_and_Funding_Pass_Due_Process_Muster [Ed: Of course the patent extremists aren't yet done trying to gut PTAB]⠀⇛ On October 13, in Mobility Workx v. Unified Patents, LLC, the Federal Circuit rejected a series of due process challenges to the structure of the Patent Trial and Appeal Board (PTAB), leaving the PTAB to continue with business as usual. The court held that the structure and funding of the PTAB do not violate constitutional guarantees of due process based on (a) the fee-generating structure of the PTAB, (b) the alleged financial interests of the PTAB judges, and (c) the Director’s delegation of authority for the institution decision to the same PTAB judges who will render a final decision if trial is instituted. The panel concluded, however, that Mobility is entitled to a remand under Arthrex for rehearing by the Director to address substantive questions, and to consider Mobility’s argument that the PTAB’s failure to issue a final determination within 12 months of institution requires dismissal of the petition or issuance of a certificate confirming the challenged claims. In reaching its conclusion that the structure and funding of the PTAB do not violate the constitution’s guarantees of due process, the court analyzed three Supreme Court cases. # ⚓ PTAB_Strategies_and_Insights_–_October_2021: Potential_Pecuniary_Interest_In_Instituting_More_AIA Proceedings_Not_Enough_To_Trigger_A_Due_Process Violation [Ed: PTAB here to stay and throw out lots of software patents]⠀⇛ We previously published an article discussing patent owner’s due process challenges based on alleged pecuniary interests of the Office and Administrative Patent Judges instituting cases to meet production goals and increase compensation. Since that article both cases, New Vision Gaming v. SC Gaming, Inc. f/k/ a Bally Gaming, Inc. (Newman, Moore, Taranto) and Mobility Workx v. Unified Patents, LLC (Newman, Schall, Dyk), have been decided. Both cases, in the end, were remanded under the Supreme Court Arthrex ruling. But while New Vision Gaming did not substantively address this due process challenge, Mobility did at length, including a Newman dissent that covered not only the due process issues, but also whether there continued to be an Appointments Clause issue because the same panel renders the institution decision and then conducts the trial. # ⚓ Sens._Leahy_and_Tillis_to_Chief_Justice_Roberts: Something’s_Up_In_Waco [Ed: A well-overdue intervention and it's good to see that Josh Landau (CCIA) writes about it, seeing there's zero journalism on patents anymore (to counter lies from litigation firms)]⠀⇛ The Senate Judiciary Committee’s IP Subcommittee had an active day yesterday with members sending out a pair of letters that suggest that they see some serious problems in the patent system. The first letter, sent by both Chairman Leahy and Ranking Member Tillis to Chief Justice Roberts, in his role as head of the Judicial Conference, expresses serious concerns about the Waco court—and especially about Judge Albright’s behavior. Referring both to Judge Albright’s history of soliciting patent cases to his court and to his poor track record at the Federal Circuit—15 grants of mandamus and counting—Sens. Leahy and Tillis express concern about the lack of guidance on case assignment within a single district for patent cases and the abuses it enables. While their letter states they’re not aware of similar problems in other single judge divisions, there’s some evidence of this type of shopping in other arenas—manipulation of bankruptcy trustees and even more concerning, forum selling in the area of large company bankruptcies. The letter closes by requesting the Judicial Conference study the abuses the present situation enables and provide recommendations for how the problem could be fixed. # ⚓ Assertion_Of_Comms_Patents_Against_Auto_Manufacturers Continues [Ed: Smug lawyers happy that Microsoft’s patent_trolls are attacking everyone in the UK]⠀⇛ Another week and another patent suit against a major auto manufacturer. This action by Intellectual Ventures against Toyota follows on from a recent patent action by Avanci against Ford. Intellectual Ventures is a US venture capital firm that claims to own over 70,000 patents. That’s a lot. The action relates to Toyota’s in-car systems including wireless hotspot, infotainment system and remote access service. With 70,000 patents, it seems difficult to make a vehicle or vehicle system that does not step on Intellectual Ventures IP rights. Given previous history, one might expect that this will result in some sort of a settlement, setting another precedent that OEMs will need to consider. Whilst the major manufacturers are the targets for now, there surely has to be a trickle down effect over time to encompass component and service suppliers. # ⚓ Neurim_v_Mylan:_A_Most_Unusual_Case_–_Take_Two_Part Two [Ed: European Patents, which are nowadays being granted in direct violation of the EPC, create 'business' to these convicted corrupt lawyers (this firm was found guilty)]⠀⇛ This is the second time writing about the Neurim v Mylan battle “take two” concerning a divisional patent (EP 3 103 443) granted on 30 June 2021 (but expires 12 August 2022). The first article ( Neurim v Mylan: Take Two) covered Neurim’s successful application for an expedited preliminary issue trial. That article also covers (some of) the twists and turns of the original Neurim v Mylan battle on the parent patent. # ⚓ Patentability_Of_Known_Substances_In_Europe [Ed: They also carry on pretending that the EPC is still being followed; EPO is so corrupt that it_violates_it routinely]⠀⇛ Article 54 EPC states that an invention shall be considered to be new if it does not form part of the state of the art. Based on this statement, you might initially consider that it is therefore not possible to obtain a patent for a substance that is already known. However, there are certain circumstances where the substance per se might be known but this does not preclude the patentability of such a substance. # ⚓ Broad_Files_Reply_to_ToolGen_Opposition_to_Broad Preliminary_Motion_No._1 [Ed: Kevin E. Noonan meanwhile carries on pushing, for personal gain, the inane notion that life and nature themselves merit a patent monopoly as if humans invented them]⠀⇛ ToolGen argued in its Opposition that the Board should deny Broad’s motion first, because Broad has neither established nor argued that dual-and single-molecule eukaryotic CRISPR is the same patentable invention, and second, that Broad’s proposed Count 2 “does not define the common claimed subject matter [because] all of ToolGen’s involved claims are limited to single- molecule RNA” species (emphasis in brief). As to the first argument, ToolGen contended that there is a distinction to be made between Broad’s position that dual- and single- molecule CRISPR embodiments are “alternative approaches” to eukaryotic CRISPR and that they are the same invention, which ToolGen asserted they are. Presciently, ToolGen argued that “Broad cannot attempt to make that showing for the first time in its reply,” citing Nau v. Ohuchida, Int. No. 104,258, 9 Paper 57, at *4 (B.P.A.I. 1999), regarding making the argument that a dual- molecule eukaryotic CRISPR system would be prima facie obvious over single-molecule embodiments, under Spine v. Biedermann Motech GmbH, 684 F. 18 Supp. 2d 68, 89 (D.D.C. 2010). And in this regard ToolGen argued that Broad had not established that Broad has best proofs that would be best adjudged for priority under Proposed Count 2. ToolGen also argued that proposed Count 2 is broader than the common claimed invention between the parties because, as instituted by the Board, existing Count 1 is limited to single-molecule RNA embodiments of eukaryotic CRISPR and that common claimed subject matter is what defines an interference, citing Beech Aircraft Corp. v. Edo Corp., 990 F.2d 1237, 1248–49, and Louis v. Okada, 59 22 U.S.P.Q.2d 1073, 2001 WL 775529 at*4 (B.P.A.I. 2001). # ⚓ U.S._Chamber_of_Commerce_Urges_Administration_to “Double_Down”_on_Global_Vaccine_Distribution [Ed: Cancel the patents, job done. But when some companies make a killing (also literally; their greed is killing millions) it's not likely to happen because they lobby and bribe officials]⠀⇛ In a letter sent to U.S. Trade Representative Katherine Tai last week, the U.S. Chamber of Commerce expressed disappointment that the Biden Administration “continues to entertain actions, such as a waiver of the TRIPS Agreement, that would undermine the pandemic response.” The Chamber instead urged the Administration “to double down on efforts to distribute vaccines globally.” The Chamber sent its letter to the U.S. Trade Representative in advance of the 12th Ministerial Conference (MC12), which will take place from November 30 to December 3, 2021 in Geneva, Switzerland (the Ministerial Conference is the top decision making body of the World Trade Organization (WTO)), noting that the MC12 “will be an inflection point for global pandemic response, the rules-based multilateral trading system, and international IP.” In its letter, the Chamber “strongly urge[s]” the Administration at the MC12 “to herald the tremendous success of the U.S. and international innovation ecosystem that continues to produce technological solutions to the technical problems of the COVID-19 pandemic.” # ⚓ EPO’s_written_decision_in_G_1/21_explains_reasoning behind_emergency_use_of_video_conference_oral proceedings [Ed: Complete, utter hogwash by EPO, once again breaking the law and rigging the courts]⠀⇛ The EPO’s Enlarged Board of Appeal yesterday released its full written decision on G1/21. This case discusses whether oral proceedings can be held by video conference without the consent of all parties. The full written decision can be found here. The decision provides the reasoning behind a preliminary order issued in July in which the Enlarged Board decided that oral proceedings before Boards of Appeal can be conducted by video conference without the parties’ consent during a “general emergency”, such as the Covid-19 pandemic. The Enlarged Board notes in the decision that, whilst video conferencing can ensure the essential features of oral proceedings before the Boards can be maintained, in person hearings are the “gold standard” and should be a default option. This default of in person proceedings can only be denied for “good reasons”. The Enlarged Board particularly points out that availability of conference rooms and interpretation facilities or intended efficiency gains would not constitute “good reasons”. To hold oral proceedings other than in person there must be a suitable alternative available (i.e. video conferencing) and circumstances that justify the alternative (e.g. international and domestic travel restrictions, quarantine requirements and EPO access restrictions). # ⚓ EPO_Issues_Written_Decision_In_G1/21_Concerning Videoconference_Oral_Proceedings [Ed: The patent litigation fanatics will do full revisionism about this scandalous_‘case’]⠀⇛ In particular, the EBA considered that a hearing held by videoconference can be regarded as “oral proceedings” within the meaning of Article 116 EPC. While the EBA seemed to accept that those involved in drawing up the European Patent Convention (EPC) had “in-person” oral proceedings in mind, and may not have envisaged videoconference as an option, the wording of Article 116 EPC places no limitation on the format of the oral proceedings. The EBA felt it would be at odds with the purpose of the EPC, which aims to support innovation and technological progress, if formats for oral proceedings supported by technological progress were to be excluded. Further, given that the purpose of oral proceedings is to allow parties a chance to plead their case orally, it cannot have been the legislator’s intent to exclude potential future formats that do indeed allow oral presentations to be made. The EBA also noted that if it were the case that a hearing held by videoconference is not “oral proceedings” within the meaning of Article 116 EPC, then this would have ramifications on the status of such hearings even if held with the consent of the parties. # ⚓ Video_Didn´t_Kill_the_(in-person)_Oral_Proceedings Star_Redux:_The_EPO_Enlarged_Board_of_Appeal_Now Explains_Why [Ed: The EPO broke the law again, and it stacked the courts to pretend this was acceptable]⠀⇛ # ⚓ QUANTUM_TECHNOLOGIES_AND_SPACE_(ESPI),_Nov_9,_2021, virtual,_9:30_am_ET [Ed: Corrupt EPO officials with no background in science (only connections to "mates") are trying to associate themselves with science while they loot everybody through the EPO's monopoly]⠀⇛ # § Trademarks⠀➾ # ⚓ Nike_Trademarks_for_Virtual_Clothing_Sparks_Metaverse Rumors⠀⇛ The new trademarks are Nike’s latest effort in exploring the metaverse, cryptocurrencies and NFT worlds. The sportswear company in 2019 secured a patent for “Cryptokicks,” or virtual collectible shoes stored on a blockchain. The patent says that when a particular sneaker is purchased, a token is unlocked and 10-digit code will then be linked to the sneaker’s owner. The owner could also “breed” custom sneakers, which then could be produced as a physical product. # ⚓ Nike_is_quietly_preparing_for_the_metaverse⠀⇛ Nike has filed seven trademark applications as it prepares to enter the metaverse. As part of the application, the company indicated its intent to make and sell virtual branded sneakers and apparel. # ⚓ [Guest_post]_The_subtle_line_between_“historical”_and “reputed”_marks_–_a_bird’s-eye_view⠀⇛ Introduced on 20 January 2020, the protection of Historical Trade Marks was designed as a tool aimed at boosting Italian companies and production and protecting them against foreign acquisitions. More in detail: according to Law Decree No 34/2019, and in line with Article 11-ter of the Italian Intellectual Property Code (IPC), a mark can be included in the register of Historical Trade Marks (the “Register”) provided that (i) it has been registered for at least fifty years – or continuous use for at least fifty years can be proven, (ii) it is used for the marketing of products or services produced in a national productive enterprise of excellence, and (iii) it is historically linked to the national territory. Article 185-ter IPC then provides that the owners or licensees of historical trade marks intending to close their production site have to notify “without delay” the Ministry of Economic Development about the project and share economic or technical reasons underlying their decision, including the steps taken to find a potential buyer. Eventually, Law Decree 34/2020 completed the legal framework, by introducing a specific Fund (Fund to safeguard employment levels and the continuation of business activity) operated by the Italian agency Invitalia with the purpose of inter alia financing the activity of owners (or exclusive licensees) of Historical Trade Marks. # ⚓ More_to_Facebook_rebrand_than_meets_the_eye:_sources [Ed: Mouthpieces of the litigation firms ignored all Facebook scandals, took note only when the company did some branding move]⠀⇛ Lawyers delve into the trademark strategy for Facebook’s Meta rebrand and explain why it might get away with having such an indistinctive name # ⚓ The_countries_and_sectors_leading_the_‘green’ trademark_race [Ed: EUIPO_is_exceptionally_corrupt, so just like corrupt EPO (same people, many overlaps) it resorts to shameless greenwashing tactics]⠀⇛ EUIPO data shows non-EU countries are applying for ‘green’ EUTMs at a higher rate than their European counterparts, but which industry comes out on top? # ⚓ Nike_Files_for_Virtual_Trademarks_for_the_Metaverse [Ed: Nike knows that it's just the name; the company is just a big bunch of sweatshops in Asia]⠀⇛ Nike could be looking at a transition into the metaverse after it filed seven new intent-to-use applications with the U.S. Patent and Trademark Office in late October, The Fashion Law reported Tuesday (Nov. 2). The applications were for several notable Nike trademarks, including the words “Nike,” “Just Do It,” “Jordan” and “Air Jordan,” along with the trademark Nike “swoosh” logo, the Jordan silhouette logo and the stylized combo of the company name and the swoosh. # § Copyrights⠀➾ # ⚓ Associate_Spotlight_with_Olivier_Lombardo [Ed: Revolving_doors_between_EPO_and_private_sector]⠀⇛ After gaining further experience in private practice and with the European Patent Office (EPO), Olivier Lombardo joined Dennemeyer & Associates in 2010. # ⚓ At_last_Spain_transposes_the_DSM_Directive⠀⇛ Spain has finally transposed the DSM Directive (DMSD), by means of a Royal Decree- law (RD-law), which was published in the Official Gazette on the 3rd of November. The same also transposes other Directives the implementation of which was pending, including Directive (EU) 2019/789 on online transmissions of broadcasting organisations and retransmissions of television and radio programmes. The implementation measures of the DSMD entered into force yesterday, the 4th of November. The transposition closely follows the DSMD in many respects. In this post I will briefly consider the implementation of Arts. 15 and 17 DSMD. As to the press publishers’ neighbouring right laid down in Art. 15 DSMD, the transposition generally sticks to the Directive’s provision, but does introduce some peculiarities which are worth noting. For instance, while the DSMD establishes that the right “shall not apply in respect of the use of individual words or very short extracts of a press publication”, the Spanish transposition seems to limit the reach of this exception. On the one hand, it provides that the right will not apply to the use of individual words, or to extracts which are very short or of little significance both in quantitative and qualitative terms. On the other hand, it establishes that this exception will only apply where the concerned online use does not prejudice the investments carried out by the publishers and news agencies, and does not affect the effectivity of the new neighbouring right. # ⚓ UFC_on_Piracy:_Suing_YouTube_&_Facebook_Not_Viable, They_Hide_Behind_the_DMCA⠀⇛ UFC Chief Operating Officer Lawrence Epstein says that his company desperately needs an update to copyright law. Suing YouTube and Facebook is not viable so it’s crucial to hold these platforms responsible for infringing content under federal law. In particular, UFC needs a takedown-and-staydown requirement and if new platforms can’t afford it, tough luck. ䷩ 𝚕𝚒𝚗𝚎 5343 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 11.08.21⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Links_8/11/2021:_LXD_4.20_and_Kdenlive_21.08.3⠀✐ Posted in News_Roundup at 7:56 pm by Dr. Roy Schestowitz 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GNOME bluefish⦈ § Contents⠀➾ * GNU/Linux o Distributions o Devices/Embedded * Free_Software/Open_Source * Leftovers * § GNU/Linux⠀➾ o § Desktop/Laptop⠀➾ # ⚓ System76_is_building_a_new_Linux_desktop_in_Rust_•_The Register⠀⇛ # ⚓ System76_Developing_a_New_Desktop_Environment_»_Linux Magazine⠀⇛ The makers of Pop!_OS are currently in the early stages of creating a brand new, non-GNOME, desktop environment. System76 is never one to settle. Consider what they’ve done to the GNOME desktop environment with their COSMIC treatment. Effectively, the company has made GNOME their own. But that wasn’t enough, so the developers have set out to create a brand new DE, from scratch, using Rust. Why? Michael Murphy, Pop!_OS maintainer for System76, said, “There are things we’d like to do that we can’t simply achieve through extensions in GNOME. Extensions in general feel like a hack. And what we want to do with our desktop differs from GNOME, so it’s not like the option to merge pop- shell and COSMIC into GNOME Shell would be a welcome thing.” Although the new desktop will not be a fork of GNOME, the developers do plan on reusing some of the current GNOME tooling, such as Mutter, KWin, and Wlroots. On this issue, Murphy said, “We’re already using gtk-rs for all of our stuff. My assumption is that it’s likely to see some components in GTK for the foreseeable future.” Murphy continues, “The shell itself though is lower level than a traditional desktop GUI toolkit. It’ll use primitives from the window manager it builds upon. If a mature Rust GUI turns up, then it could be used in the future of course. I’d generally like to use the best tools where possible.” The System76 desktop will also be distribution- agnostic, so it won’t require Pop!_OS to run. As well, the developers plan on sticking to (when possible) the standards, set by FreeDesktop. o § Server⠀➾ # ⚓ Kubernetes:_Announcing_the_2021_Steering_Committee_Election Results⠀⇛ The 2021 Steering Committee Election is now complete. The Kubernetes Steering Committee consists of 7 seats, 4 of which were up for election in 2021. Incoming committee members serve a term of 2 years, and all members are elected by the Kubernetes Community. This community body is significant since it oversees the governance of the entire Kubernetes project. With that great power comes great responsibility. You can learn more about the steering committee’s role in their charter. # ⚓ CRN_recognizes_Red_Hat_OpenShift_and_Red_Hat_Enterprise Linux_as_Tech_Innovators⠀⇛ Red Hat has been recognized by CRN®, a brand of The Channel Company, as a winner of the 2021 CRN Tech Innovator Awards. Red Hat OpenShift came out on top in the Container Technology category, with Red Hat Enterprise Linux honored as a finalist for Hybrid Cloud Infrastructure. This annual award program showcases innovative vendors in the IT channel across 47 different technology categories, in key areas ranging from cloud to storage to networking to security. To determine the winners, a panel of CRN editors reviewed hundreds of vendor products using multiple criteria, including key capabilities, uniqueness, technological ingenuity and ability to address customer and partner needs. # ⚓ History_of_Open_Source_Identity_Management_(part_1)_| Ubuntu⠀⇛ Few computing concepts are as ubiquitous as identity and access management. There isn’t a single day that goes by without us being asked for credentials, passwords or pin codes. Yet very few know the origins and the evolution of the technologies behind them. This is the first of two blog posts where we will look at the history of open-source identity management. We will cover the main open-source protocols and standards that shaped it, from its origins to the modern days. This post will focus on the origins and the two major “legacy” protocols: Kerberos and LDAP. # ⚓ Common_Kubernetes_terminology_you_should_know⠀⇛ Kubernetes has become the de facto system for organizations to manage their Linux containers. It works across multiple cloud environments, and you can use it to manage microservices and deploy applications. This list of ubiquitous Kubernetes terminology can prepare you to work with Kubernetes and help you to better understand how exactly this popular container management platform functions. o § Audiocasts/Shows⠀➾ # ⚓ Zap:_Package_Manager_For_Your_AppImage_Needs_–_Invidious⠀⇛ AppImages certainly don’t need a package manager to function but there are some advantages such as easier management that can be offered by them so today we’re looking at Zap to see what it an do to help. # ⚓ LHS_Episode_#439:_OLF_2021_Deep_Dive⠀⇛ In this deep dive episode of Linux in the Ham Shack, we talk to Beth Lynn Eicher from the upcoming Ohio Linux Fest. We go over a bit of the history of OLF and then Beth Lynn gives our listeners the low down on everything that’s going to happen at this year’s event. The pandemic has made in-person conferences difficult but this time around it sounds like it’s going to be a lot of fun with both a local and virtual presence. So if you’re going to be around Columbus, Ohio on December 3-4 or you have some free time to visit online, make sure to come by the show. o § Kernel Space⠀➾ # ⚓ Linux_5.16_Improves_Laptop_Support_For_System76_&_HP_Omen, Better_AMD_S0ix_–_Phoronix⠀⇛ The platform-drivers-x86 pull is exciting as usual for the in-development Linux 5.16 kernel. o § Applications⠀➾ # ⚓ LXD_4.20_has_been_released⠀⇛ The LXD team is very excited to announce the release of LXD 4.20! This is one very busy release with a lot of new features. VM users will be happy to see the initial implementation of live migration and core scheduling support. Container users are getting new configuration keys to set sysctls. Then the bulk of the new features are all network related with peer network relationships, network zones for auto-generated DNS and SR-IOV accelerated OVN networks. And lastly, on the clustering front, it’s now possible to better control what servers will be receiving new workloads. # ⚓ LXD_4.20_released⠀⇛ o § Instructionals/Technical⠀➾ # ⚓ What_Is_dirname_$0_and_Usage_Examples_–_ByteXD⠀⇛ In this tutorial, we’ll explore the dirname command and how to use dirname $0 to get the location of the running bash script. Furthermore, we will discuss how to retrieve an absolute path using the dirname command. # ⚓ [Workaround]_Blurry_/_Pixelated_Text_Font_in_Ubuntu Software_of_Ubuntu_21.10_|_UbuntuHandbook⠀⇛ The Ubuntu Software app in Ubuntu 21.10 Impish has an ugly font rendering on default Wayland. The text in the app looks a bit pixelated. I found the issue firstly when Impish was in beta stage. The issue was reported to also affect LibreOffice, Chromium, and other Snap apps, though most of them has been updated with it fixed. # ⚓ Libvirt/KVM_Backup_on_Debian_Bullseye_–_Michael_Ablassmeier –_..⠀⇛ The libvirt and qemu versions in Debian Bullseye support a new feature that allows for easier backup and recovery of virtual machines. Instead of using snapshots for backup operation, its now possible to enable dirty bitmaps. Other hypervisors tend to call this “changed block tracking”. Using the new backup begin approach, its not only possible to create live full backups (without having to create an snapshot) but also track the changes between so called checkpoints, which is very useful for incremental backups. Over the course of the last few months, i have been working on a simple backup and recovery utility called virtnbdbackup # ⚓ Enrico_Zini:_An_educational_debugging_session⠀⇛ This morning we realised that a test case failed on Fedora 34 only (the link is in Italian) and we set to debugging. # ⚓ How_to_install_ONLYOFFICE_on_Elementary_OS_6.0_– Invidious⠀⇛ In this video, we are looking at how to install ONLYOFFICE on Elementary OS 6.0. # ⚓ How_to_install_Wizard101_on_a_Chromebook_with_Crossover 21⠀⇛ Today we are looking at how to install Wizard101 on a Chromebook with Crossover 21. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below. # ⚓ Configure_OpenVPN_Clients_to_use_specific_DNS_Server_– kifarunix.com⠀⇛ This is a quick tutorial on how to configure OpenVPN clients to use specific DNS server. OpenVPN server can be configured to enable the clients to use specific DNS server for hostname resolution. # ⚓ LFCS_–_Managing_Groups_|_Linux.org⠀⇛ The previous article covered Managing Users. Administrators need to be able to not only manage new and existing users, but also the Groups that the users can belong to on a system. Keep in mind that these skills are more beneficial in a larger network in a domain-style environment than on a single system. If you worked in a corporation with multiple departments then it is much easier to place all users in a department into a single Group for that department. Once you assign permissions to the Group then all users have the same permissions. Of course, if you assign more permissions to specific Users, then those Users will have more permissions above the Group permissions. # ⚓ How_to_Install_Contao_on_Ubuntu_20.04_|_RoseHosting⠀⇛ Contao is a powerful open source content management system (CMS) that is easy to use, intuitive, and versatile and it allows you to create websites in multiple languages and themes. Contao can also be integrated into a regular Symfony application. In this tutorial, we will show you how to install Contao on Ubuntu 20.04. # ⚓ Install_HPLIP_3.21.10_In_Ubuntu_21.04_/_Debian_/_Zorion_| Tips_On_UNIX⠀⇛ This tutorial will be helpful for beginners to install HPLIP 3.21.10 in Ubuntu 21.04, DEBIAN 11, and Zorion OS 16 & 15. HPLIP – HP Linux Image and Printing, developed by HP for Printing, scanning, and faxing with HP inkjet and laser-based printers in Linux platforms. The latest version of HPLIP 3.21.10 contains new printer support and added support to the new Distro’s and the hplip installer is available for download from SourceForge. # ⚓ How_to_install_Varnish_Cache_for_Nginx_on_CentOS_8/ Almalinux_8_–_Unixcop_the_Unix_/_Linux_the_admins_deams⠀⇛ Varnish cache is also known as a caching HTTP reverse proxy. Varnish cache will boost your server to load web pages very fast, and this is the one of the key factor by Google to rank higher. It is an open-source, high-performance HTTP accelerator designed for speeding up web servers. Hi guys ! In this tutorial, you’ll learn how to Install Varnish Cache for Nginx on CentOS 8. Varnish cache is used to increase the speed or accelerate web servers to serve the web pages. So, Varnish cache is a free web application accelerator. Varnish cache saves the web pages in- memory so that every time when a user request/ access any web pages it will be loaded from in- memory instead of a refresh. Varnish is an HTTP accelerator designed for content-heavy dynamic web sites as well as APIs. In contrast to other web accelerators, such as Squid, which began life as a client-side cache, or Apache and nginx, which are primarily origin servers, We will go with Nginx in this tutorial. Let’s begin ! # ⚓ How_to_install_OpenLitespeed_server_with_php8_for_Debain11/ Ubuntu21_–_Unixcop_the_Unix_/_Linux_the_admins_deams⠀⇛ OpenLiteSpeed is an easy-to-use, open-source web server. It offers unbeatable features and performance to your sites along with top-notch security. The server understands all the apache rewrite rules and has intelligent cache acceleration features that let you implement the fastest caching on your server. In this tutorial, we will install & access the openlitespeed GUI. We have used 21.10 server # ⚓ How_to_Add_a_User_to_Sudoers_in_AlmaLinux_or_Rocky_Linux⠀⇛ Rocky Linux and AlmaLinux are the top replacement Operating system for CentOS. This project came into existence once CentOS moved from an enterprise- stable operating system to an upstream development branch of RHEL. Sudo stands for “substitute user do” or “super user do”. This gives a current user to run programs with security privileges temporarily, by default the root user. The sudoers file is located at /etc/ sudoers which contains the security policy for system users and groups to determine sudo privileges. In this tutorial learn how to add a user to sudoers in AlmaLinux or Rocky Linux. # ⚓ How_to_Use_getopts_in_Bash_–_ByteXD⠀⇛ In Linux, tasks can be automated by writing several commands in one script and then executing the script whenever the same set of commands are needed. These scripts accept a variety of command- line arguments, which are often passed collectively when the script is executed. The good thing is that a built-in function (called getopts) is available in Linux that is used to parse these command-line arguments. In this tutorial, you will learn about the getopts function in detail and how to use it to handle command-line arguments very effectively. This is explained with the help of several examples. The getopts function is used to parse the arguments that are passed to a script through the command line. In other words, getopts look for all the options that your script might take in. Keep in mind that when the options are passed to a script, they are passed using a dash (-). This is analogous to using options when you use Linux commands. For instance, you can consider the example of ls or cd commands which take a variety of options to provide different outputs (e.g., ls -l). # ⚓ How_To_Install_VS_Codium_on_Fedora_35_Workstation_– Citizix⠀⇛ VS Codium is a binary releases of VS Code without MS branding, telemetry andlicensing. It is a source-code editor made by Microsoft for Windows, Linux and macOS. The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. It is a streamlined code editor with support for development operations like debugging, task running, and version control. It aims to provide just the tools a developer needs for a quick code- build-debug cycle and leaves more complex workflows to fuller featured IDEs, such as Visual Studio IDE. # ⚓ How_to_install_Steam_in_KDE_neon⠀⇛ Installing Steam in a Linux distro should be easy, right? Well. Even though, technically, it ought to be a simple one mouse click or one-liner in a terminal window, things aren’t always quite as trivial. A while back, I had issues with missing 32-bit libraries for Steam (and some other programs) in Linux Mint. The likes of Fedora or AlmaLinux need third-party repositories. I had issues with Steam not running under Nouveau. Manjaro had different versions of Steam available, and they didn’t always work perfectly. With KDE neon, just recently, I encountered a new problem. When I search for Steam on the command line, I get no results. It would appear that Steam isn’t there. Which is strange, because neon is based on Ubuntu, and Steam has been in the repos since day one. All right, let’s analyze and fix this issue. # ⚓ Installing_Arch_Linux_Plus_DTOS_–_Invidious⠀⇛ Short tutorial showing how to install Steam in KDE neon by adding 32-bit architecture support # ⚓ Deploying_Ubuntu_Instances_with_MAAS_–_Invidious⠀⇛ MAAS (Metal as a Service) gives you the ability to provision physical and virtual servers via an easy to use web console. You can use MAAS to deploy Ubuntu with ease, and it even supports PXE boot in order to provide you with a full deployment solution. In this video, you’ll get an overview of MAAS and how to set it up. Thanks to Linode for sponsoring this tutorial. o § Games⠀➾ # ⚓ Fantastic_retro-FPS_DUSK_gets_The_New_and_Old_Update_for Linux_|_GamingOnLinux⠀⇛ A little later than expected but DUSK now has The New and Old Update available in the native Linux version. This is the free update that came along with the Nintendo Switch release of the game, adding in numerous enhancements that were done for it. # ⚓ Paradox_continue_attempting_to_make_Surviving_Mars:_Below and_Beyond_worth_it_|_GamingOnLinux⠀⇛ Surviving Mars: Below and Beyond released back in early September, and to say the reviews have been poor would be quite the understatement but they’re continuing to try and improve it. Released on November 4 was the first content update for Below and Beyond, where they said the first focus was around making it easier to use the Underground, Asteroid Lander and Elevator. Not only that, they’re trying to give you more of a point to doing either for your main colony. That is probably the biggest issue with the expansion, it added other places to explore and build, which sounded nice but for so little gain. # ⚓ Valheim_gets_another_small_release_fixing_up_crashes,_a little_optimization_too_|_GamingOnLinux⠀⇛ Ahead of another week of survival, Iron Gate has updated their popular co-op survival game Valheim with a mixture of different improvements but no major changes. For starters they upgrade the Unity game engine from 2019.4.24f1 to 2019.4.31f1, which was “long- awaited” that should help fix some random crash bugs to do with pathfinding. Hooray for more stability! Additionally the comfort calculation was performance optimized, Mead bases show status effects on tooltip and some localization updates. [...] Looks like the popularity of Valheim is holding pretty stable now at around 30,000 players online each day. The most recent Hearth & Home major update seemed to bring back quite a lot of players. o § Desktop Environments/WMs⠀➾ # ⚓ LXQt_1.0.0_Review_–_Best_Lean_Linux_Desktop,_Ever⠀⇛ We review the LXQt 1.0.0 Desktop with release highlights, installation instructions. # § K Desktop Environment/KDE SC/Qt⠀➾ # ⚓ Kdenlive_21.08.3_released⠀⇛ The last maintenance release of the 21.08 series is out fixing many same track transition issues. Other noteworthy improvements include loop zones don’t stop playback when adding effects, added ability to set clip thumbnails when hover seeking clips in the Project Bin and proxies can now be automatically generated for .mlt files. # ⚓ KDE_Gear_21.12_releases_branches_created⠀⇛ Please make sure you commit anything you want to end up in the 21.12 releases to them. We’re already past the dependency freeze, so no new dependencies or increasing of dependency versions in the stable branches. The feature freeze, tagging and release of the beta (21.11.80) is in four days,11 November. # § GNOME Desktop/GTK⠀➾ # ⚓ Endless_Orange_Week:_Hack_content_creators_platform⠀⇛ This week (Nov 8 – 12) I am participating in Endless Orange Week, a program where the entire Endless team engages in projects designed to grow our collective learning related to our skills, work and mission. We propose a project, that could be anything, and then work during the whole week, without distraction. I’ve choosed to work on the Hack project, that’s a really nice project that needs some love, because since the past year, we have other priorities, so there’s no time to improve the Hack app. # ⚓ A_good_next_step_–_Mantoh_Nasah_Kuma⠀⇛ Some months back (in March to be precise), I completed an amazing outreachy internship at GNOME. The months after that have been full of activity. In July I had the opportunity of presenting at the first open source conference I ever attended- GNOME’s Annual Developer Conference (GUADEC). Here I shared the contributions I made to the community by working on GNOME’s JavaScript Debugger where I wrote JavaScript code, improved on some areas of the documentation and helped new contributors find their way when I could. o § Distributions⠀➾ # ⚓ Kali_Linux_vs._BackBox_vs._Parrot_OS:_Which_One_Should_You Choose?⠀⇛ When it comes to digital security, you could either trust that everything is protected or confirm this for yourself. You might even be the person other people go to, to confirm their security for them. Either way, a Linux distribution focused on penetration testing provides the tools you need for the job. Kali Linux, BackBox, and Parrot OS are three of the most popular options available for ethical hacking and security testing. Need help making a decision? Let’s dive in. # ⚓ Nemomobile_in_November/2021⠀⇛ NemoMobile 0.6 was released. Horay! What else? We have new boot splash, reworked device lock, new policy kit agent and old-new package manager, updates of bluetooth, pulse audio, the translations was updated. PineTab initial support. # ⚓ [Release_notes]_Suomenlinna_4.3.0⠀⇛ Jolla Phone is not supported anymore. OS release 3.4.0 was the last one for this device launched 7 years ago. The lowest supported kernel version of Sailfish 4 in the remaining Sailfish OS devices is 3.10. It is in Jolla C, Jolla Tablet and Xperia X. The instructions for installing Sailfish OS to Sony Xperia X, Xperia XA2, Xperia 10, and Xperia 10 II (mark 2) devices are here – covering Windows, Linux, and macOS computers. # § Gentoo Family⠀➾ # ⚓ The_future_of_Python_build_systems_and_Gentoo⠀⇛ Over the years, the distutils stdlib module has been used to build setup.py scripts for Python packages. In addition to the baseline functions providing a build system CLI for the package, it provided the ability to easily extend the build system. This led both to growth of heavily customized setup.py scripts as part of some packages, as well as third-party build systems based on distutils, most notably setuptools. This eventually led to deprecation of distutils themselves (see: PEP 632). Python 3.10 is already warning of distutils deprecation, and the current plan is to remove it in Python 3.12. Ahead of that, the development has moved to a dedicated pypa/ distutils repository, and the copy of that is bundled within setuptools. setuptools still uses the stdlib distutils by default. However, some packages already switch to the bundled copy, and upstream plans on using it by default in the future (see: Porting from Distutils). At this point, I don’t think there is an explicit need for Gentoo to act here. However, it seems reasonable to avoid using distutils as the build system for Gentoo projects. Since the setuptools copy of distutils is different from the one included in CPython (and PyPy) and at the moment it does not carry the full set of historical Gentoo patches, it probably makes sense to test package compatibility with it nevertheless. # § Slackware Family⠀➾ # ⚓ October_’21_updates_for_OpenJDK_7_and_8_|_Alien Pastures⠀⇛ The newly released icedtea 2.6.28 and 3.21.0 build OpenJDK 7u321_b01 and OpenJDK 8u312_b07 respectively. These releases include the October 2021 security fixes for Java 7 and 8 from Oracle. [...] My Java 7 and Java 8 packages (e.g. openjdk7 and openjdk… or openjre7 and openjre) can not co-exist on your computer because they use the same installation directory. You must install either Java 7 or Java 8. Remember that I release packages for the JRE (runtime environment) and the JDK (development kit) simultaneously, but you only need to install one of the two. The JRE is sufficient if you only want to run Java programs (including Java web plugins). Only in case where you’d want to develop Java programs and need a Java compiler, you are in need of the JDK package. # ⚓ Secure_Boot_support_landed_in_liveslak_1.5.0⠀⇛ Secure Boot is part of the UEFI specification and first appeared in the Unified Extensible Firmware Interface (UEFI) 2.3.1 specification (Errata C). It is meant to prevent the execution of unauthorized code upon boot of a computer. Most modern Personal Computers will have a way of enabling Secure Boot in UEFI, but it is common to leave it disabled if you are not running a Microsoft OS on it since Microsoft controls Secure Boot. For dual-boot scenario’s the story is different however. Microsoft Windows 8 and 10 advise to have Secure Boot enabled but don’t enforce it, but as far as I know, for Microsoft Windows 11 enabling Secure Boot will be a requirement to get full upgrade support. # § IBM/Red Hat/Fedora⠀➾ # ⚓ Automation_for_the_win:_How_I_accidentally_built_a serverless_application⠀⇛ As a developer advocate, one of the largest challenges I face is how to teach people to use our company’s products. To do this well, you need to create workshops and disposable environments so your students can get their hands on the actual technology. As an IBM employee, I use the IBM Cloud, but it is designed for long-term production usage, not the ephemeral infrastructures that a workshop requires. We often create systems to work around the limitations. Recently in updating the deployment process of such a system, I realized I had created a full serverless stack — completely by accident. This blog post details how I accidentally built an automated serverless automation and introduces you to the technology I used. # ⚓ Last_of_original_SCO_v_IBM_Linux_lawsuit_settled_| ZDNet⠀⇛ While at the Linux Foundation Members Summit in Napa, California, I was bemused to find that an open-source savvy intellectual property attorney had never heard of SCO vs. IBM. You know, the lawsuit that at one time threatened to end Linux in the cradle? Well, at least some people thought so anyway. More fool they. But now, after SCO went bankrupt; court after court dismissing SCO’s crazy copyright claims; and closing in on 20-years into the saga, the U.S. District Court of Utah has finally put a period to the SCO vs. IBM lawsuit. # ⚓ New_ways_to_contribute:_From_public_accountant_to quality_engineer⠀⇛ Red Hat’s Products and Technologies organization is doing game-changing work in the IT industry, so we’re taking a closer look at some of the talented Red Hatters from around the world who are enabling our continued evolution. In showcasing their unique stories, it’s clear that there’s no one path to finding success as a Red Hatter. For each of us, it’s about open collaboration and building something together. Associate Software Quality Engineer Dita Stehlikova has seen the enablement that comes with open source technology firsthand. “I’ve had my laptop since my university days, and it constantly had recurring problems. I’d get anxious with every update. Is this going to be the fix for my problem? But each time the issues would come right back. It was quite stressful. So I switched my operating system to Fedora, and it was like a miracle. Those recurring issues just stopped. That laptop still runs like clockwork to this day. “Looking back, it’s a small thing, but that really was when I saw how incredible the open source model could be. It’s a good system that allows everyone to contribute to making things better. That’s when I fell in love with the concept of open source, and it’s been a big part of my career ever since.” # ⚓ Red_Hat_Enterprise_Linux_9_Beta_Features_Enhanced_Web Console_Performance_Metrics,_Enhanced_Security_And More⠀⇛ Red Hat has announced the beta release of the next major update to its Red Hat Enterprise Linux (RHEL) platform. Based on upstream kernel version 5.14, RHEL 9 Beta is designed for demanding hybrid multicloud deployments that range from physical, on-premises, public cloud to edge. RHEL 9 Beta will run on four different hardware architectures: Intel/AMD64 (x86_64), ARM 64-bit (aarch64), IBM Power LE (ppc64le) and IBM Z (s390x). It features enhanced web console performance metrics allowing you to better identify the potential causes of performance bottlenecks; Kernel live patching via the web console; and several image builder improvements, including the ability to build RHEL 8 and RHEL 9 images via a single build node, better support for customized file systems (non-LVM mount points) and bare metal deployments. # § Canonical/Ubuntu Family⠀➾ # ⚓ Ubuntu_Weekly_Newsletter_Issue_708⠀⇛ Welcome to the Ubuntu Weekly Newsletter, Issue 708 for the week of October 31 – November 6, 2021. o § Devices/Embedded⠀➾ # ⚓ Here_come_the_Raspberry_Pi_Compute_Module_pseudo-clones⠀⇛ Pine64 launched an RPi CM4-like “SOQuartz” module for $35 (2GB) to $75 (8GB) with WiFi/BT and SATA support. Meanwhile, Radxa revealed a similarly RK3566-equipped “Radxa CM3” that also adds USB 3.0. Both modules can use CM4 carriers. In June, when Pine64 launched its Quartz64 model- A SBC, the company revealed preliminary details for a SOQuartz compute module, which similarly runs Linux or Android on the quad-core, Cortex-A55 Rockchip RK3566. Aimed initially at developers, the SOQuartz has now launched in 2GB LPDDR4 ($40), 4GB ($50), and 8GB ($75) variants, which are priced the same as equivalent RPI CM4 modules. The module has dual 100-pin B2B connectors like the Raspberry Pi Compute Module 4, enabling users to plug into a CM4 carrier board, much like Antmicro’s upcoming, RISC- V based (StarFive 71×0) ARVSOM module. # ⚓ What_Can_You_Do_With_a_Raspberry_Pi_400?⠀⇛ Can you really buy a full-fledged personal computer for $70? Yes you can. With an all-in-one design reminiscent of classic 1980s/1990s home computers, Raspberry Pi 400 is built into a keyboard and can be connected to any monitor or TV with an HDMI socket. Based on the same quad-core system-on-chip as the Raspberry Pi 4, it can run a host of desktop applications in the official Raspberry Pi OS based on Debian Linux. Let’s take a closer look at the Pi 400’s capabilities and what you can use it for. # ⚓ postmarketOS_Release:_v21.06_Service_Pack_4⠀⇛ A fresh new service pack bringing some nice features from edge to stable. This is the last service pack in the v21.06 release cycle, we plan to publish a new postmarketOS v21.12 release in December, based on the upcoming Alpine 3.15 and a soon-to-be-created new branch from postmarketOS edge. # ⚓ Linux_Smartphone_News_Roundup:_New_postmarketOS,_Manjaro, Nemo,_and_Sailfish_OS_builds,_Phosh_0.14,_and_more⠀⇛ The developers of postmarketOS also have a new release featuring Phosh 0.14 user interface. This latest update to the stable channel of postmarketOS also brings a feature-complete multi-factor authentication app, an improved modem helper daemon, and more. This will be the last service pack for postmarketOS v21.06, with the next stable release expected to be v21.12, which should launch in December. # ⚓ postmarketOS_+_mainline_for_the_OnePlus_5/5T!⠀⇛ The OnePlus 5 is a popular high-end phone from 2017, featuring the Qualcomm Snapdragon 835 SoC and Adreno 540. It has a 1080p display and up to 8GB of RAM. Mainline support for the device has been around for a while, since early 2020 in fact. Unfortunately, the Snapdragon 835 SoC it is based on lacks the same interest upstream that has benefited SDM845 devices so much, requiring a lot of work to reach a usable level of functionality. Despite that, after a lot of time and effort from Jami Kettunen and several other Snapdragon 835 developers, we can finally welcome a postmarketOS port based on a close-to-mainline kernel! A surprising amount of the hardware already works, although there are a few known stability issues, such as the requirement to run diag-router, a tool meant for debugging the modem to prevent WiFi from crashing. # ⚓ Hand_Reballing_And_A_Steady_Hand_Makes_A_Raspberry_Pi_800⠀⇛ The all-in-one Raspberry Pi 400 computer is a capable device, but those seeking its maximum power may be disappointed by its 4 GB of memory. When the Pi 4 and Compute Module 4 have double that figure, surely the Pi 400 could catch up! A reddit user called [Pi800] rose to the challenge by replacing the 4 GB chip from the Pi 400 with the 8 GB chip from a Pi Compute Module, resulting in the so- called Pi 800, a working 8 GB all-in-one Pi. As a piece of work it’s a deceptively straightforward yet extremely fiddly piece of soldering that requires a steady hand for even the most skilled of solderers. What takes it beyond the norm though is the reballing process. A ball-grid- array chip has a grid of small balls of solder on its underside that make the contacts, and these melt when it is soldered so require replacement before reworking. This is normally done with a template of carefully aligned holes to line up balls of solder in a stream of hot air, but lacking the template in this case the job was done by hand, laboriously ball by ball. A soldering task we’d hesitate to take on ourselves, so we’re impressed. # ⚓ Tiger_Lake-H_module_enables_2.5GbE_with_TSN_and_up_to_8K displays⠀⇛ Portwell’s Linux-ready “PCOM-B657VGL” Basic Type 6 module runs on an 11th Gen H-series CPU with up to 64GB DDR4, quad and 8K display support, 2.5GbE, 4x SATA, PCIe Gen4 x16, 8x PCIe Gen3, and 4x USB 3.2 Gen 2. Portwell announced a COM Express Basic Type 6 module equipped with Intel’s 11th Gen H-series (Tiger Lake-H) processors. The PCOM-B657VGL is designed for mission critical use conditions and AI edge computing applications in industrial automation, machine vision, communication, IoT, edge computing, medical equipment, transportation, and automated test equipment. The module is also suitable for graphic-intensive applications including gaming, digital signage, smart retail, and more. # § Open Hardware/Modding⠀➾ # ⚓ WinnerMicro_W806_240_MHz_MCU_finds_it_way_into_a_$2 development_board_–_CNX_Software⠀⇛ I’ve just been notified about an inexpensive board (HLK-W806) based on WinnerMicro W806 32-bit XT804 (XuanTie E804) microcontroller clocked at up to 240 MHz and equipped with 1MB flash and 288KB RAM. XuanTie is the microcontroller family from Alibaba’s subsidiary T-Head Semiconductor, notably XuanTie RISC-V cores, but I’ve just learned not all XuanTie cores are based on the RISC-V architecture, and as we’ll see below, Xuantie E804 core appears to be based on the C-Sky architecture. It may still be interesting, as it’s in the STM32 board price range (pre-2020), but with a much higher frequency, so let’s have a look. # ⚓ Adafruit_AVRProg_Grows_UPDI_Interface_Support_| Hackaday⠀⇛ Making a small number of things with an embedded application is pretty straightforward, you usually simply plug in a programmer or debugger dongle (such as an AVRISP2) into your board with an appropriate adaptor cable, load your code into whatever IDE tool is appropriate for the device and hit the program button. But when you scale up a bit to hundreds or thousands of units, this way of working just won’t cut it. Add in any functional or defect-oriented testing you need, and you’re going to need a custom programming rig. Adafruit have a fair bit of experience with building embedded boards and dealing with the appropriate testing and programming, and now they’ve updated their AVR Programming library to support the latest devices which have moved to the UPDI (Unified Programming and Debug Interface) programming interface. UPDI is a single-wire bidirectional asynchronous serial interface which enables programming and debugging of embedded applications on slew of the new AVR branded devices from Microchip. An example would be the AVR128DAxx which this scribe has been tinkering with lately because it is cheap, has excellent capacitive touch support, and is available in a prototype-friendly 28-pin SOIC package, making it easy peasy to solder. # ⚓ Connect_Arduino_Cloud_to_LoRaWAN_and_The_Things Stack⠀⇛ The Things Stack (TTS) and Arduino Cloud are now fully interfaced and open up a world of connected opportunities. When you configure a LoRaWAN device now, it’ll automatically be registered on The Things Stack platform, too. # § Mobile Systems/Mobile Applications⠀➾ # ⚓ 8_Firefox_pro_tips_and_tricks_for_Android_and_iOS_ (plus_a_few_more)⠀⇛ # ⚓ 7_Amazing_Charging_Animations_You_Should_Install_On Your_Android⠀⇛ # ⚓ Qualcomm_Tech_Summit_2021:_Qualcomm_announces_event for_next_premium_Android_processor:_Dates,_expectations and_more_–_Times_of_India⠀⇛ # ⚓ Redge_Media_teams_up_with_Beacon_for_Android_TV_and RDK_–_Digital_TV_Europe⠀⇛ # ⚓ Here’s_how_to_disable_the_Game_Dashboard_icon_pop-up on_Android_12⠀⇛ # ⚓ How_To_Enable_Camera_&_Microphone_Toggles_On_Android 12_Or_Pixel⠀⇛ # ⚓ LG_Android_11_update_(LG_UX_10)_list_of_eligible devices_&_release_date⠀⇛ # ⚓ LG_Wing_5G_delivers_a_unique_swiveling_Android experience_at_$330_(Refurb,_Orig._$999)_–_9to5Toys⠀⇛ # ⚓ Google_Chrome_for_Android_devices_to_get_this_new ‘privacy’_feature_–_Times_of_India⠀⇛ o § Free, Libre, and Open Source Software⠀➾ # ⚓ Umple:_Open-source_UML_editor⠀⇛ Umple is a cross-platform open-source model- oriented programming system that enables the developer to create UML models without breaking a sweat. # ⚓ The_Apache_News_Round-up:_week_ending_5_November_2021⠀⇛ Welcome November –we’ve closed October with another great week.

Documenting outages helps internet access defenders understand when and where they took place even when authorities or service providers may deny them. When large numbers of Firefox users experience connection failures for any reason, this produces an anomaly in the recorded telemetry data. At the country or city level, this can provide a corroborative signal of whether an outage or intentional shutdown occurred. Several large technology companies, including Google and Cloudflare, publicly share data about outages of consumer-facing products in different ways. But researchers and journalists can usually only hone in on the exact nature of an outage by combining data from multiple sources. # ⚓ [Repost]_8_Firefox_pro_tips_and_tricks_for Android_and_iOS_(plus_a_few_more)⠀⇛ With something like 15 billion mobile phones in the world, our collective thumbs are getting a workout from swiping and tapping tiny screens all day.

Following his tenure at Disney, Eric was CFO at Helix Education, a provider of technologies and services to power data-driven higher education growth, and at the programmatic advertising exchange OpenX Technologies. # § Productivity Software/LibreOffice/Calligra⠀➾ # ⚓ Community_Member_Monday:_Nige_Verity⠀⇛ I’ve been working in IT since the mid 1980s, spread across the aerospace, defence, science and financial services sectors. In the beginning I was mostly coding and testing, but as time went by I found myself working on requirements, designing systems and documenting them as much as doing any actual coding. I first learned to program using Fortran on a VAX computer running the VMS operating system. Since then I’ve used all sorts of hardware and programming languages, even including a brief spell updating an ancient legacy system written in Algol running on an Elliott computer of late 1960’s vintage, for which the program was loaded from paper tape. This was an experience that gave me enormous respect for the programmers of the past for whom that was hi-tech. Having worked on some extremely complex systems over the years I have come to value simplicity. When I am developing software for my own use my tool of choice these days is Gambas – an amazing but surprisingly little- known IDE, best described as “Visual Basic for Linux”, only Gambas is far superior to VB and leaves Python for dead in terms of productivity and performance. Away from IT I am a musician – playing flamenco and blues guitar, and also the piano. In parallel with IT I’ve worked on the fringes of the art world, helping to organise four large-scale public art shows in recent years. Although originally from London, I am blessed to live in rural South Shropshire, surrounded by farmland and arguably the most beautiful scenery the UK has to offer. # ⚓ LibreOffice_QA/Dev_Report:_October_2021⠀⇛ # § Programming/Development⠀➾ # ⚓ What_Is_the_Difference_Between_GUI_and_CLI?⠀⇛ There is no specific answer to this question, as the GUI and CLI both have pros and cons. Choosing an interface to use depends on what task you need to execute on your computer. Although the GUI is easy to learn and popular, learning the basics of the command- line interface is useful, whether you end up using it as your go-to interface option. # ⚓ Linux_Fu:_Automatic_Header_File_Generation_| Hackaday⠀⇛ I’ve tried a lot of the “newer” languages and, somehow, I’m always happiest when I go back to C++ or even C. However, there is one thing that gets a little on my nerves when I go back: the need to have header files with a declaration and then a separate file with almost the same information duplicated. I constantly make a change and forget to update the header, and many other languages take care of that for you. So I went looking for a way to automate things. Sure, some IDEs will automatically insert declarations but I’ve never been very happy with those for a variety of reasons. I wanted something lightweight that I could use in lots of different toolsets. I found an older tool, however, that does a pretty good job, although there are a few limitations. The tool seems to be a little obscure, so I thought I’d show you what makeheaders — part of the Fossil software configuration management system. The program dates back to 1993 when [Dwayne Richard Hipp] — the same guy that wrote SQLite — created it for his own use. It isn’t very complex — the whole thing lives in one fairly large C source file but it can scan a directory and create header files for everything. In some cases, you won’t need to make big changes to your source code, but if you are willing, there are several things you can do. # § Perl/Raku⠀➾ # ⚓ gfldex:_2nd_class_join⠀⇛ # ⚓ Rakudo_Weekly_News:_2021.45_Two_Commas⠀⇛ With only being a few hours late to make it to last week’s Rakudo Weekly News, Oleksandr Kyriukhin was nonetheless glad to be able to announce another release of the Comma IDE for subscribers, as well as a new free Comma Community Edition!

In the 1920s, a state-of-the- art AM radio contained several vacuum tubes, a few enormous inductors, capacitors and resistors, several dozen meters of wire to act as an antenna, and a big bank of batteries to power the whole thing. Today, you can listen to a dozen music streaming services on a device that fits in your pocket and can do a gazillion more things. But miniaturization is not just done for ease of carrying: it is absolutely necessary to achieve the performance we’ve come to expect of our devices today. # ⚓ Own_The_Night_With_This_Ludicrously_Bright_DIY_Flashlight_| Hackaday⠀⇛ Given the proclivities of our community, it’s no surprise that this is hardly the first powerful flashlight we’ve seen. This one broke the 100-Watt barrier with a single COB LED, while this ammo-can version sports an even higher light output. Neither of them looks much like a traditional flashlight, though, which is where [Maciej]’s build has the edge. o § Integrity/Availability⠀➾ # § Proprietary⠀➾ # § Pseudo-Open Source⠀➾ # § Privatisation/Privateering⠀➾ # § Linux Foundation⠀➾ # ⚓ Linux_Foundation_and_Graviti Announce_Project_OpenBytes_to_Make Open_Data_More_Accessible_to_All⠀⇛ Linux Foundation Membership Summit — The Linux Foundation, the nonprofit organization enabling mass innovation through open source, announced the new Project OpenBytes spearheaded by Graviti.

Discovered by SentinelLabs’ researcher Max Van Amerongen, the vulnerability tracked as CVE-2021-43267 exists in the Transparent Inter Process Communication (TIPC) module of the kernel, specifically in a message type that allows nodes to send cryptographic keys to each other. # § Privacy/Surveillance⠀➾ # ⚓ Human_Rights_Organizations_Condemn_Use_of NSO_Group’s_Pegasus_Against_Palestinians_– Access_Now⠀⇛ The following statement condemning the use of Pegasus spyware against six Palestinian human rights defenders was issued today by seven human rights organizations, including Access Now… # ⚓ NSO’s_Pegasus_surveilled_Palestinian activists_—_it’s_time_for_a_moratorium_on spyware_sales_–_Access_Now⠀⇛ Access Now and a coalition of human rights organizations condemn the hacking of six Palestinian human rights defenders’ devices with NSO Group’s Pegasus spyware, demand a moratorium on spyware sales, and call for immediate U.N. intervention. “The evidence keeps mounting — Israel’s use and creation of spyware is unsafe,” said Marwa Fatafta, MENA Policy Manager at Access Now. “The world cannot sit back and watch NSO Group technology target and persecute Palestinians any longer, we’re calling on the U.N. and global actors to denounce these unlawful attacks, and ensure it doesn’t happen again.” o § Defence/Aggression⠀➾ # ⚓ How_Burhan’s_coup_could_halt_Sudan’s_return_to_the international_community⠀⇛ Gen Burhan — the chairman of the Sudanese Sovereign Council — led a military coup in Sudan on October 25, 2021. Gen Burhan has justified Monday’s coup, saying it was necessary to “avoid civil war” and blamed political infighting. The forces behind the coup arrested Prime minister Abdalla Hamdok, along with many ministers and politicians. The international community responded to the coup in several ways. The US condemned the coup and suspended 700 million US dollars in aid for Sudan. The UK and EU each condemned the military coup and The African Union suspended Sudan’s membership and described the coup as “unconstitutional.” # ⚓ SIMs_to_leaflets:_Sudanese_find_ways_to_skirt_net_outage⠀⇛ From using international SIM cards to deploying relatives in the diaspora to relay information, Sudanese citizens are finding ways to communicate in a bid to circumvent telecommunications restrictions imposed after the military seized power last week. o § Monopolies⠀➾ # ⚓ Online_marketplaces_score_win_with_anti-counterfeit amendment_–_POLITICO⠀⇛ Senators are coalescing behind the recent House version of legislation aimed at cleaning up online marketplaces. ䷩ 𝚕𝚒𝚗𝚎 7051 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ 11.08.21⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ Gemini_version_available_♊︎ ✐ Links_8/11/2021:_Raspberry_Pi_OS_Updated,_EasyOS_3.1.9_and_Maui_2.1.0 Released⠀✐ Posted in News_Roundup at 12:40 pm by Dr. Roy Schestowitz 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GNOME bluefish⦈ § Contents⠀➾ * GNU/Linux o Distributions o Devices/Embedded * Free_Software/Open_Source * Leftovers * § GNU/Linux⠀➾ o § Desktop/Laptop⠀➾ # ⚓ TUXEDO_Nano_Pro_is_an_AMD-Powered_Ultra-Mini_Linux_PC_– It’s_FOSS_News⠀⇛ The German-based Linux PC manufacturer has just added another exciting product to their mini-PC lineup.

Arguably most notable for KVM with Linux 5.16 is the introduction of the RISC-V architecture code for the Kernel-based Virtual Machine. The KVM RISC- V hypervisor support depends upon the RISC-V ISA’s hypervisor extension, which was recently frozen. Now to wait for RISC-V processors to market that are performant and supporting the extension… # ⚓ What_is_the_Linux_kernel?⠀⇛ For casual users and less experienced fans, Linux is an open source operating system. For purists, however, the title “Linux” is reserved for the kernel that powers the operating system. If you’re curious about what the Linux kernel is, let’s answer that question, with a focus on more non- expert users. [...] Every operating system has a kernel. Windows, macOS, iOS, Android, Chrome OS and Linux each have a low-level system that is responsible for interfacing all software with the computer’s physical hardware. Without the kernel, none of your applications would be able to use the physical computer; applications like Firefox, Chrome, LibreOffice, MS Office or Outlook would not work. The kernel is also responsible for allowing processes to exchange information using what is called Inter-Process Communication (IPC). # ⚓ Raspberry_Pi_Compute_Module_4_Supported_By_Mainline_Linux 5.16_–_Phoronix⠀⇛ Linux 5.16 is an action-packed kernel with a ton of exciting additions and improvements. Adding to the growing list of changes to look forward to with v5.16 is mainline support for the Raspberry Pi Compute Module 4. Released just over one year ago was the Raspberry Pi Compute Module 4 as their system-on-module variant of the Raspberry Pi 4. # § Graphics Stack⠀➾ # ⚓ xwayland_21.1.3⠀⇛ I'm pleased to announce the Xwayland 21.1.3 release. No change compared the release candidate (21.1.2.901). Olivier Fourdan (1): Bump version to 21.1.3 git tag: xwayland-21.1.3 # ⚓ XWayland_21.1.3_Released_With_Support_For_NVIDIA’s 495_Driver_GBM⠀⇛ While just a point release, XWayland 21.1.3 that is out this morning is exciting in that it adds support for using NVIDIA’s new proprietary driver that supports the GBM API for enhancing its Wayland support. XWayland 21.1.3′s main feature is supporting the NVIDIA GBM back-end. The code now supports setting the GLVND library based on the back-end name. There is also a fix from NVIDIA for using EGL_LINUX_DMA_BUF_EXT for creating GBM buffer object EGLImages. # ⚓ Etnaviv_Gallium3D_Switches_Over_To_NIR_By_Default_– Phoronix⠀⇛ It’s been a while since last having any major progress to report on Etnaviv, the open- source Mesa Gallium3D driver supporting Vivante graphics IP. But a rather fundamental change was made this past week in that Etnaviv is now (finally) using NIR by default. Emma Anholt made the change so that Etnaviv Gallium3D is now using NIR by default rather than TGSI as Gallium3D’s long-standing intermediate representation. o § Applications⠀➾ # ⚓ Best_Free_and_Open_Source_Alternatives_to_Adobe_Premiere Pro⠀⇛ Adobe is a large multinational computer software company with over 22,000 employees. Its flagship products include Photoshop, Illustrator, InDesign, Premiere Pro, XD, Acrobat DC, and the Portable Document Format (PDF). The products are wrapped up and marketed as the Creative Cloud, a subscription- only way of accessing more than 20 desktop and mobile apps and services for photography, design, video, web, UX, and more We are long-standing admirers of Adobe’s products. They develop many high quality proprietary programs. It’s true there are security and privacy concerns in relation to some of their products. And there’s considerable criticism attached to their pricing practices. But the real issue is Adobe Creative Cloud does not support Linux. And there’s no prospect of support forthcoming. o § Instructionals/Technical⠀➾ # ⚓ How_To_Install_KVM_on_Debian_11_–_idroot⠀⇛ In this tutorial, we will show you how to install KVM on Debian 11. For those of you who didn’t know, KVM (Kernel-based Virtual Machine) is an open- source full virtualization solution for Linux Systems running on x86 hardware with virtualization extensions (Intel VT or AMD-V). You can use KVM to run multiple operating systems such as Windows, *BSD, Linux distribution using virtual machines. Each virtual machine has its private disk, graphics card, network card, and more. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by- step installation of the KVM virtualization on a Debian 11 (Bullseye). # ⚓ How_to_Install_the_Etherpad_Collaborative_Web_Editor_on Rocky_Linux_8⠀⇛ Etherpad is an open-source online editor providing collaborative editing in real-time in the browser.

We will also use Nginx as a reverse proxy for the application and install an SSL certificate using Let’s Encrypt to enable HTTPS connections to our Etherpad instance. # ⚓ How_to_Install_OpenEMR_Medical_Office_Workflow_Software_on Ubuntu_20.04_–_VITUX⠀⇛ A medical office’s workflow can be a tangled mess of electronic documents, including insurance forms and appointments. In order to streamline the process for both patients and staff members, it is necessary that they have access to efficient software – which offers all necessities from scheduling weeks in advance with no reminders around receptionists’ availability slots or how much inventory each pharmacy has on hand at any given moment. Are you looking for a medical practice that can fit your needs? Many options are available, including proprietary software. However, there is another option: open source solutions. The OpenEMR project offers an easy way to get started with this type of digital health innovation. In this guide, we will walk you through the process of installing OpenEMR on an Ubuntu Server 20.04. # ⚓ How_to_Install_Gradle_Build_Tool_on_Debian⠀⇛ Gradle is a build automation tool that is built on the ideas of Apache Ant and Apache Maven. Gradle replaces the XML form used by Apache Maven for defining the project settings with a Groovy-based domain-specific language (DSL). Gradle is using a Groovy-based DSL, which is more convenient for developers. This DSL also provides for dependency management, automatic downloading and documentation. It can be used to compile the source code, run tests and generate reports on the same project in a single command-line. While Gradle is primarily a build tool, it can also be used as a general-purpose task runner. It provides the ability to create native software packages in Windows EXE installer, and dmg packages. Gradle does not provide dependency management since it can load plugins to support various source code management tools, but Gradle has a rich API that allows you to create custom tasks or even new plugins. There are also various community-provided plugins available for different types of dependency management. The Gradle tool is written in Java, but it can work with any language as long as there are plugins available for the respective language. Linux users will be happy to know that Gradle is available natively for Linux. Gradle has many advantages over Maven, including faster incremental builds due to the use of Ivy dependency management, which actually makes it possible for developers to avoid using maven-release-plugins. The release process itself becomes less painful. # ⚓ How_to_Upgrade_to_Ubuntu_22.04_LTS_(Jammy_Jellyfish)_Beta from_21.10_–_LinuxCapable⠀⇛ The new Ubuntu 22.04 LTS is fast approaching, with it recently receiving its official codename Jammy Jellyfish. For now, the schedule is set for release on April 21, 2022, but this may change in the future at a moment’s notice. # ⚓ Use_Cloudformation_to_create_an_RDS_MySql_Instance_on_AWS⠀⇛ The AWS Relational Database Service (RDS AWS) is a web service that makes it easier to set up & operate a relational database in the cloud. To understand more about RDS search for “How to setup an RDS MySql (Relation Database MySql ) instance on AWS” article. AWS CloudFormation allows us to use programming languages (yaml/json) or a simple text file to model and provision all the resources needed for our applications. This gives us a single source of truth for our AWS resources. In this article, we will see the steps to create an RDS MySql Instance using Cloudformation Stack. # ⚓ Add,_Delete_And_Grant_Sudo_Privileges_To_Users_In_Fedora_– OSTechNix⠀⇛ Using sudo program, we can elevate the ability of a normal user to run administrative tasks, without giving away the root user’s password in Linux operating systems. This guide explains how to add, delete and grant sudo privileges to users in Fedora 35 desktop and server editions. I’ve divided this guide in three sections. The first section teaches you how to create a new user. In the second section, you’ll learn how to give sudo access to the existing user. And in the last section, you will know how to remove sudo access from a user. I’ve also provided example commands in each section, so you can understand it better. First, we will start with giving sudo access to a new user. # ⚓ Using_RHEL_System_Roles_to_manage_Linux_at_scale⠀⇛ One such RHEL management tool to consider is RHEL System Roles, a collection of supported Ansible roles and modules providing consistent and abstracted configuration interfaces to manage RHEL at scale. There are a large variety of roles that cover many aspects of RHEL management. RHEL System Roles are currently distributed as an RPM in RHEL and as a collection on Ansible Automation Hub (available for Ansible subscribers). Ansible also supports a new format called execution environments, which are packaged as container images. RHEL System Roles doesn’t currently have an execution environment container image, but the upstream Linux System Roles project does. During our recent presentation Secure and monitor RHEL: Using the Linux System Roles execution environment with Ansible Automation Controller at AnsibleFest 2021, we covered how you could use this upstream execution environment and Ansible Automation Controller to help secure and monitor RHEL. # ⚓ How_to_Install_Linux_Kernel_5.15_on_AlmaLinux_8⠀⇛ Linux kernel 5.15 is out with many new features, support, and security. The Linux 5.15 kernel release further improves the support for AMD CPUs and GPUs, Intel’s 12th Gen CPUs, and brings new features like NTFS3, KSMBD (CIFS/SMB3), and further Apple M1 support, amongst many other changes and additions. # ⚓ How_to_Install_Xubuntu_Desktop_on_Ubuntu_20.04⠀⇛ One of the wonderful things about the Linux operating system is its vast array of customization options. If you are using a system with a graphical user interface, you can tweak almost anything – the desktop background, wallpaper, icons, and even installing a different desktop environment to have a change in the look-and-feel. You can have multiple Desktop environments installed on your Linux system or you can decide to remove others and remain with one. The choice is usually entirely up to you. One of the desktop environments that you can use to add some oomph and improve your user experience is the Xubuntu desktop environment. Xubuntu is stable and relatively lightweight compared to the GNOME desktop environment which ships with Ubuntu 18.04 and later versions. It’s highly customizable and is kind on the computing resources such as CPU and RAM. Xubuntu is, therefore, an ideal environment to turn to if you want to speed up your PC particularly if you are running a system with low computing specifications. # ⚓ 20_Basic_Ubuntu_Commands_for_Beginners_–_LinuxStoney⠀⇛ Ubuntu is one of the most customizable Linux distributions available today. Almost all Linux enthusiasts start with Ubuntu. And if you’re new to Ubuntu, then check out this list of basic commands that will help you get acquainted with the system. The commands will help you to perform some basic actions in the operating system. To help you get off to a good start, here are the top 18 basic Ubuntu commands for beginners. # ⚓ How_to_Check_and_Repair_a_File_System_in_RHEL_Linux⠀⇛ RHEL (Red Hat Enterprise Linux) is famed for its integration of file system administration utilities upon its installation. These utilities make it possible for the Linux file system to retain a healthy performance status. The Linux file systems get scanned for any performance shortcoming and instantaneously get repaired through the help of toolkits like fsck (file system check). The Linux operating system automates the execution of this file scanning and repairing tool during system boot. However, it is also possible for an RHEL user to manually invoke a terminal command associated with filesystem check and repair without rebooting the system. # ⚓ How_I_build_command-line_apps_in_JavaScript_| Opensource.com⠀⇛ Including options for your users is an important feature for any application, and Commander.js makes it easy to do. What’s your favorite JavaScript command-line builder? Take our poll. # ⚓ Live_Debugging_Techniques_for_the_Linux_Kernel,_Part_2_of 3⠀⇛ # ⚓ Write_your_first_CI/CD_pipeline_in_Kubernetes_with_Tekton_| Opensource.com⠀⇛ Tekton is a Kubernetes-native open source framework for creating continuous integration and continuous delivery (CI/CD) systems. It also helps to do end- to-end (build, test, deploy) application development across multiple cloud providers or on- premises systems by abstracting away the underlying implementation details. # ⚓ Implement_user_auth_in_your_project_in_minutes_with SuperToken⠀⇛ Implementing a user authentication in a project, requires time, especially when it is created from scratch. Many developers tend to use social login, built-in libraries or tend to create them from scratch. With SuperToken, all you need to do is implement, test, and deploy. SuperToken is an open-source, self-hosted solution that allows developers to implement user authentication in minutes. It features a full authentication workflow that takes the hassle out of the equation. # ⚓ Playing_Mario_on_Linux_(Ubuntu,_Manjaro,_Fedora)_– LinuxH2O⠀⇛ This guide is pretty straightforward, it allows you to play your favorite retro game Mario on your Linux distribution. It doesn’t matter which distro you are using – Ubuntu, Mint, Fedora, Manjaro or many be Debian. All you have to do is just follow along and you will be able to live your childhood again. Mario is one of the first games that became viral back in the day. The games have grown far more advanced and sophisticated, but Mario’s essence is still in our hearts. We all wanted to save the queen from the monster. We played the game so many times that it has been encoded in our brain permanently and there is nothing that can erase or replace Mario. o § Games⠀➾ # ⚓ Splitgate_expands_the_options_available_for_making_Custom Games_more_unique_|_GamingOnLinux⠀⇛ 1047 Games recently released a big update to Splitgate, their free to play first-person shooter with portals to enable players to make more interesting Custom Games. You’re not just limited to casual and competitive modes, as you can also make your own with various rules. This November update includes an overhaul to custom game lobbies, an easier way to edit the game modes and maps. This new system looks a lot better, with you easily picking through various main modes each with different variants available with a lot more presets to choose from. The new game settings UI is also adjusted so it’s split between things like Map, Mode, Team and Player options where you can really tweak all the individual bits – like giving each team different options. # ⚓ Heroes_of_Might_and_Magic_II_recreation_fheroes2_v0.9.9 further_improves_the_original_|_GamingOnLinux⠀⇛ Another great sounding releasing for the game engine reimplementation of Heroes of Might and Magic II (fheroes2) is available right now to play on modern systems. Ensuring that all parts of the game are correct they added the missing part of the Captain’s Quarters in the Barbarian castle, the Cave in the Warlock castle is not rendered any more when it’s not built but the Waterfall is, plus some fixes for the blurred road and incorrect rendering of the Moat for the Captain’s Quarters. # ⚓ HYPERCHARGE:_Unboxed_details_Steam_Deck_support,_shows_a quick_video_|_GamingOnLinux⠀⇛ HYPERCHARGE: Unboxed is another developer who will be ensuring their games works nicely with the Valve Steam Deck. What is it? Hypercharge is a classic-style Third and First-Person Shooter inspired by Toy Story and Small Soldiers. It focuses on Wave-Based Shooting with Defense Building mechanics. You must complete the mission of Sgt. Max Ammo and prevent the HYPER- CORE from being destroyed. # ⚓ Bohemia_Interactive_are_‘looking_into’_DayZ_for_the_Steam Deck_|_GamingOnLinux⠀⇛ One tough uphill battle currently facing Steam Play Proton and the Steam Deck is still anti-cheat. While there has been improvements, it’s still not an ideal situation but at least one more developer is looking into it with Bohemia Interactive for DayZ. It’s a little different to support native Linux builds of games, as developers would use the native Linux versions of anti-cheat but for games that don’t support Linux like that, they will rely on the Steam Play Proton compatibility layer to run the Windows version. The problem there remains that with Easy Anti-Cheat developers need to upgrade their SDK, then of course it all needs ensuring it works correctly. With BattleEye previously mentioning what sounded like the same. # ⚓ RollerCoaster_Tycoon_2_reimplementation_OpenRCT2_v0.3.5 brings_new_features_|_GamingOnLinux⠀⇛ OpenRCT2 continues being an impressive free and open source game engine reimplementation for RollerCoaster Tycoon 2, allowing you to play it nicely cross-platform on modern systems. # ⚓ How_to_improve_the_performance_of_games_in_Linux_using GameMode⠀⇛ Feral Interactive is a company and distributor of games for different platforms (macOS, Linux, iOS devices, Android devices and Nintendo Switch) to which we can attribute several quite good titles. Well, for some time now the company has been working and improving its tool called “GameMode” which is an impressive tool that can improve performance while playing on Linux. o § Desktop Environments/WMs⠀➾ # ⚓ Is_System76_Going_to_Drop_Gnome_for_a_Home_Brewed,_Scratch Made_Desktop?⠀⇛ On Sunday, Phoronix’s Michael Larabel reported on a rumor that Linux hardware vendor, System76, is developing a homegrown desktop environment that won’t be based on Gnome or any other existing DE, presumably for its Ubuntu-based Pop!_OS distribution. This came after System76 engineer and Pop!_OS maintainer Michael Murphy wrote in a thread on Reddit that the company is developing its “own desktop.” # ⚓ System76′s_Pop!_OS_Linux_to_create_Rust_based_desktop⠀⇛ System76′s Pop!_OS Linux distribution already has their own “COSMIC” desktop that is based on GNOME but apparently it has had enough and wants to move to a Rust based desktop. A Reddit discussion over the possibility of seeing a KDE flavor of Pop!_OS, revealed the more unexpected news that the outfit was working on its “own desktop.” # ⚓ Oh,_Wow!_Pop!_OS_Linux_Devs_Are_Creating_a_New_Rust-based Desktop_Environment⠀⇛ Earlier this year, System76 introduced their desktop environment (DE) “COSMIC” based on GNOME. The COSMIC desktop aimed to offer a polished and more functional experience when compared to GNOME. Considering my previous experience with Pop!_OS, System76 always seems to have top-notch implementations to offer the best possible user experience with Pop!_OS. While they tried to evolve with their desktop environment flavor, it looks like it isn’t feasible anymore. In a Reddit poll (via Pop!_OS Sub-reddit), Pop!_OS users wondered if Pop!_OS would introduce a KDE- flavoured desktop environment. # § K Desktop Environment/KDE SC/Qt⠀➾ # ⚓ Maui_2.1.0_Release⠀⇛ This version of Maui brings new features and bug fixes to Maui’s applications and the frameworks they rely on. The changes introduced in this release will make your experience with Maui Apps much more enjoyable and feature rich. o § Distributions⠀➾ # § New Releases⠀➾ # ⚓ EasyOS_version_3.1.9_released⠀⇛ Two very significant changes this time: firstly, both SeaMonkey and Firefox in the build, and secondly, have moved from an ALSA- only system to Pulseaudio, with Pipewire included in the build (but Pulseaudio set as the default). I would have liked to bump the version to 3.2, but the move to Pulseaudio is bound to have issues that I have not yet discovered. So, we need one or two releases to find and fix these. Well, there are other significant changes, not just those two. The kernel is now 5.10.77 and has been compiled with the ‘wireguard’ module, and the ‘wireguard-tools’ package is in the build. Firefox can be run on the main desktop or in a container — you will find “www” icons on the desktop for both of these. They are both very secure, as on the main desktop Firefox runs as user ‘firefox’ in its own sandbox. Firefox supports automatic updating, but I have set it to ask first. You can do it manually: if you go to “Settings” and scroll down, there is a button to update. A very curious thing: Firefox running on the main desktop, requires the “Restart to update Firefox” button to be clicked-on twice — after the first restart, scroll down in “Settings” and you have to click that button again. However, running in a container, the restart button only has to be clicked-on once. Very odd. # § IBM/Red Hat/Fedora⠀➾ # ⚓ Welcoming_Phlyt’s_team_of_cloud-native_development experts_to_Red_Hat⠀⇛ We are pleased to share that the team from Phlyt, experts in cloud-native development, has joined Red Hat to enable us to help even more customers with digital transformation initiatives. Red Hat already equips customers across industries with the people, process, and technology needed for an era when every CIO is a cloud operator. With the addition of the Phlyt team and their expertise, we’re scaling Red Hat Consulting’s efforts to help customers who want to bring modern technologies to enterprise environments. Phlyt is a Toronto-based consulting company that provides expertise, products and toolkits to help organizations adopt cloud- native technologies. The Phlyt team is focused on developing cloud-native applications and helping organizations to deliver software more effectively and with a faster time to market. We believe that cloud-native technologies like Linux containers and Kubernetes are at the foundation of digital transformation. However, according to 451 Research, part of S&P Global Market Intelligence, 88% of organizations reported deficits in cloud expertise.1 As the IT landscape continues to grow in complexity and scale, cloud-native skills play a critical role in helping organizations modernize their IT infrastructure and development tools. # ⚓ Test-driven_development_with_Quarkus⠀⇛ Want to learn more about developing applications with Quarkus? Download our free e-book Quarkus for Spring Developers, which helps Java developers familiar with Spring make a quick and easy transition. Many development teams today have adopted test-driven development (TDD). Continuous testing support in Quarkus enables developers to take advantage of this practice. When running Quarkus Dev Mode, you can enable continuous testing with the press of a key, empowering Quarkus to automatically rerun tests affected by a code change in the background. Quarkus understands which tests are affected by classes and methods within the application. As you make code changes, you get immediate feedback if the change passes your existing test suite. This capability is integrated directly into Quarkus—no IDE or special tooling is required. The future of developer productivity and joy is now! This article walks you through a TDD approach to building an application and highlights the benefits that Quarkus brings. The completed example you should have after completing the steps in this article can be found in this GitHub repository. # ⚓ Optimize_Node.js_images_with_the_UBI_8_Node.js minimal_image⠀⇛ Node.js 14 is available as a UBI (Universal Base Image) minimal image on Red Hat Enterprise Linux. Minimal images are typically used in conjunction with a larger build image. The larger builder image contains all the dependencies and tools needed for your application’s build process, whereas the smaller runtime image contains just the dependencies needed to run your application. The UBI minimal images minimize what is included in the image to reduce their size. For example, the full Node.js 14 UBI image is about 225MB (610MB uncompressed), whereas the slim image is about 70MB (189MB uncompressed), less than a third the size. A smaller image means less code in production, which in turn reduces your deployment’s potential attack surface and potentially speeds up your builds. You can read more about UBI minimal images in its documentation. You can deploy the Node.js minimal image through various deployment methods. This article shows you how to use the images through Dockerfiles and through chained builds on Red Hat OpenShift. # ⚓ Transformational_leadership:_4_key_behaviors_of transformational_leaders⠀⇛ It’s pure joy to be in the presence of transformational leadership. The air and light around you takes on a different quality – the world seems clear, and exciting, and yours for the taking. You believe you can do anything – and you’re excited to see where that leader will go next. Conversely – and sadly, we’ve all been here – it’s soul-destroying to be around transactional leaders. Whether you’re watching in disgust as a leader painfully works their way down a checklist of inane tasks with an exhausted group, or you’re holding the phone away from your ear as an irate manager rants incoherently about some imagined mis-step, it’s easy to completely lose the sense of purpose that, according to Mercer research, is the unmet need common across all generations in the workplace. # ⚓ Burnout_busters:_7_ways_leaders_can_protect_and energize_teams⠀⇛ Two years ago, the World Health Organization officially added burnout to the International Classification of Diseases, citing it as an occupational phenomenon. The pandemic put additional strain on workers across industries, and while the worst of the global crisis may be over, employee well-being remains a major concern across industries and functions. Burnout rose by almost nine percent between April and July 2021, according to the Glint Employee Well-Being Report – a 12 percent increase from the prior July. Gallup recently announced plans to launch a Worldwide Stress Index, following what it found was the most stressful year in history. Stress overall has become such an important topic that Gallup recently announced plans to launch a Worldwide Stress Index, following what it found was the most stressful year in history. A record-high 40 percent of adults surveyed said they had experienced a lot of stress the previous day during Gallup’s 2020 research – a five percent jump over the prior year. For IT organizations charged with meeting relentless demands for digital transformation, the risk of burnout is a significant concern. “There are three underlying reasons for potential burnout: a shrinking window of transformation opportunity; paradigm shifts across all industries in business models post-COVID; and the fact that we are still in a recessionary environment due to drops in consumption and stress in global supply chains meaning [IT organizations must] ‘do more with less,’” says Sri Manchala, author of Crossing the Digital Fault Line: 10 Rules of Highly Successful Leaders in Digitalization and CEO of digital transformation services firm Trianz. “Burnout is clearly a concern on the global technology workforce. Some of [the impacted professionals] could be yours and some could be your tech service providers.” # § Debian Family⠀➾ # ⚓ Raspberry_Pi_OS_Updated_For_Debian_11_Bullseye, Desktop_Transitions_To_GTK3+Mutter⠀⇛ Raspberry Pi OS as the official operating system for the Raspberry Pi single board computers has been updated against Debian 11 “Bullseye”. Raspberry Pi OS has shifted its package base from Debian 10 to Debian 11 now that Bullseye is out as stable and in good shape the past few months. Besides upgrading the underlying packages against the new Debian release, Raspberry Pi OS has finished migrating its own desktop components from GTK2 to GTK3. The Raspberry Pi desktop should now be in good shape and happily running on GTK3. GNOME’s Mutter has also replaced Openbox as the window manager used on Raspberry Pi OS. # ⚓ Official_Raspberry_Pi_OS_Is_Now_Based_on_Debian_GNU/ Linux_11_“Bullseye”⠀⇛ The latest Raspberry Pi OS release, dated October 30th, 2021, is the first to switch bases from the old-stable Debian GNU/Linux 10 “Buster” to the Debian GNU/Linux 11 “Bullseye” operating system series, and it uses the Linux 5.10.63 LTS kernel by default. But the Debian Bullseye rebase is just the cherry on top, as the newest Raspberry Pi OS release features all of its desktop components and applications build against the GTK+ 3 open-source application framework for the in-house built PIXEL desktop environment based on LXDE. # ⚓ Raspberry_Pi_OS_upgraded_to_Debian_11_“Bullseye”_– CNX_Software⠀⇛ Debian 11 “Bullseye” was released in August 2021, and I was expecting Raspberry Pi OS to soon get upgraded to the latest version, especially the last time around, in 2019, Raspian Buster was released even before the official Debian 10 “Buster” release, although the reason was Raspberry Pi 4 launch. This time around it took longer, but the good news is that Raspberry Pi OS has just been upgraded to Debian 11, meaning it benefits from the new features such as driverless printing, in-kernel exFAT module, “yescrypt” password hashing, and packages upgraded to more recent versions. o § Devices/Embedded⠀➾ # ⚓ The_Raspberry_Pi_CM4_Begets_A_Form_Factor_|_Hackaday⠀⇛ It has become the norm for single-board computers to emerge bearing more than a passing resemblance to the Raspberry Pi, as the board from Cambridge sets the hardware standard for its many competitors. This trend has taken an interesting new turn, as a new board has emerged that doesn’t sport the familiar 40-pin connector of the Pi Model B, but the more compact from factor of the Compute Module 4. The Radxa CM3 sports a Rockchip RK3566 quad core Cortex-A55 running at 2.0 GHz, and is to be made available in a variety of memory specifications topping out at 8 MB. It is hardware compatible with the Pi CM4, and should be usable with carrier boards made for that module. We’ve looked at the CM4 as the exciting face of the Raspberry Pi because the traditional boards have largely settled into the same-but-faster progression of models since the original B+ in 2014. The compute module offers an accessible way to spin your own take on Raspberry Pi hardware, and it seems that this new board will only serve to broaden those opportunities. Radxa are the company behind the Rock Pi series of more conventional Raspberry Pi clones, so there seems every chance that it will reach the market as promised. # ⚓ SOQuartz_–_Raspberry_Pi_CM4_compatible_Rockchip_RK3566_SoM launched_for_$35_and_up_–_CNX_Software⠀⇛ Radxa CM3 Raspberry Pi 4 alternative was just introduced yesterday, but today, Pine64 SOQuartz Compute Module has just become available for $34.99 and up. Pine64 announced the Raspberry Pi Compute Module 4 compatible Rockchip RK3566 system-on-module (SoM) last June, and today the company/community launched three SOQuartz models with a wireless module and equipped with either 2GB, 4GB, or 8GB RAM. # § Open Hardware/Modding⠀➾ # ⚓ Flip-Chip_KiCad_Templates_|_Hackaday⠀⇛ We like retro-computing and we like open source standards that allow easy project sharing. Vintage DEC computer enthusiast [Jay Logue] combines both of these in his recent project on GitHub, where he shares several KiCad templates for making your own Flip-Chip modules. Although named after the semiconductor packaging technique we are familiar with today, DEC Flip-Chips were introduced in 1964 as a modular electronics packaging system. These were used in many of DEC’s Programmable Data Processor (PDP) computers, beginning with the PDP-8 in 1965. DEC also had a Digital Laboratory Module family, which was a roll-your-own custom electronic system. The 1968 Digital Logic Handbook shows the available modules, and has the look and feel of the TTL Cookbook book which would come along six years later. # ⚓ Adding_Brakes_To_Actuated_Fingers_|_Hackaday⠀⇛ Building exoskeletons for people is a rapidly growing branch of robotics. Whether it’s improving the natural abilities of humans with added strength or helping those with disabilities, the field has plenty of room for new inventions for the augmentation of humans. One of the latest comes to us from a team out of the University of Chicago who recently demonstrated a method of adding brakes to a robotic glove which gives impressive digital control (PDF warning). # § Mobile Systems/Mobile Applications⠀➾ # ⚓ Here’s_How_Web_Browsers_On_Android_Share_Every_Move You_Make_On_The_Web_|_HotHardware⠀⇛ # ⚓ Android_Car_Keys,_What_is_It_and_How_Does_it_Work?_| Tech_Times⠀⇛ # ⚓ Samsung_One_UI_4.0_(Android_12)_update_tracker: Eligible_devices_&_more⠀⇛ # ⚓ How_To_Use_The_Expanded_Screenshot_Feature_In_Android 12?⠀⇛ # ⚓ Galaxy_S20_will_soon_get_Android_12-based_One_UI_4 beta_update_–_SamMobile⠀⇛ # ⚓ Should_Google_consider_tweaking_Android_12_‘At_a glance’_widget?⠀⇛ # ⚓ 5_Things_To_Do_After_Installing_Android_12⠀⇛ # ⚓ Some_Google_Pixel_phones_suffer_from_battery_drain with_Android_12⠀⇛ # ⚓ Google_Pixel_Android_12_bugs,_problems,_&_issues tracker⠀⇛ # ⚓ PUBG_Mobile_1.7_Beta_APK_download_link_and installation_guide_for_Android_phones⠀⇛ # ⚓ What_Is_Android_One?_A_Brief_History_Of_One_Of_The Biggest_Google_Projects⠀⇛ # ⚓ How_to_fix_missed_call_notifications_not_showing_in android?_5_best_ways⠀⇛ # ⚓ Qualcomm_Snapdragon_898_is_likely_coming_soon,_expect it_in_2022′s_top_Android_phones_|_TechRadar⠀⇛ # ⚓ Google_Embraces_Large-Screen_Android_Devices_at DevSummit_21⠀⇛ o § Free, Libre, and Open Source Software⠀➾ # ⚓ Outline:_An_Open-source_modern_Wiki_engine_for_teams_and communities⠀⇛ The Outline app is a free self-hosted wiki engine and collaborative knowledge base for teams. Wiki engines are built to ease collaborative content creation for teams, organizations, and communities. However, many current open-source wiki engines are old, Outline and some others are new modern recreation of the experience for professional teams and enterprises. # § Web Browsers⠀➾ # § Mozilla⠀➾ # ⚓ LibreWolf:_An_Open-Source_Firefox_Fork_Without the_Telemetry⠀⇛ Firefox is one of the best web browsers for Linux. However, some users do not appreciate the presence of telemetry. In addition to that, some prefer a browser that’s tuned for the best possible privacy and security out-of- the-box, even if Firefox offers one of the best customization capabilities. LibreWolf is the answer for all those users if you do not want distracting features of Firefox and want a private web experience without tweaking anything from your side. # § SaaS/Back End/Databases⠀➾ # ⚓ PostgreSQL:_DynamoDB_fdw_1.0.0_released⠀⇛ DynamoDB FDW 1.0.0 is newly released. # ⚓ PostgreSQL:_PostgreSQL_Weekly_News_–_November_7, 2021⠀⇛ PG Build 2021 will be held online on 30 November and 1 December 2021 09:00-17:00 GMT.

ODB C++ ORM version 2.5.0-b.21 released. DynamoDB FDW 1.0.0 released. Babelfish, a MS SQL Server compatibility layer for PostgreSQL, released. # § Programming/Development⠀➾ # ⚓ 6_Excellent_Free_Books_to_Learn_Coq_–_LinuxLinks⠀⇛ Coq is a dependently typed language. This means that the types of the language may depend on the values of variables. In this respect, it is similar to other related languages such as Agda, Idris, F*, Lean, and others. Via the Curry-Howard correspondence, programs, properties and proofs are formalized in the same language. Coq is developed in OCaml and shares some syntactic and conceptual similarity with it. Coq is a language containing many fascinating but difficult topics. Here’s our recommended free books to learn Coq. * § Leftovers⠀➾ o § Integrity/Availability⠀➾ # § Proprietary⠀➾ # ⚓ Microsoft’s_expired_cert_brings_these_Windows_apps_to their_knees._–_Invidious⠀⇛ # ⚓ Microsoft_will_now_snitch_on_you_at_work_like_never before⠀⇛ I feel sure there are many American workers who have put the whistle in their mouths, like former Facebook employee Frances Haugen, but been too afraid to blow it. [...] The first is headlined: “Microsoft 365 compliance center: Insider risk management — Increased visibility on browsers.” It all sounded wonderful until you those last four words, didn’t it? For this is the roadmap for administrators. And when you give a kindly administrator “increased visibility on browsers,” you can feel sure this means an elevated level of surveillance of what employees are typing into those browsers. In this case, Microsoft is targeting “risky activity.” Which, presumably, has some sort of definition. It offers a link to its compliance center, where the very first sentence has whistleblower built in: “Web browsers are often used by users to access both sensitive and non-sensitive files within an organization.” And what is the compliance center monitoring? Why, “files copied to personal cloud storage, files printed to local or network devices, files transferred or copied to a network share, files copied to USB devices.” You always assumed this was the case? Perhaps. But now there will be mysteriously increased visibility. “How might this visibility be increased?,” I hear you shudder. Well, there’s another little roadmap update that may, just may, offer a clue. # § Security⠀➾ # ⚓ Security_updates_for_Monday⠀⇛ Security updates have been issued by Debian (containerd, redis, and sqlalchemy), Fedora (kernel, radeontop, rpki-client, and webkit2gtk3), openSUSE (java-1_8_0-openj9, libvirt, mailman, transfig, and webkit2gtk3), Oracle (thunderbird), SUSE (libvirt), and Ubuntu (icu). # ⚓ Tips_to_Enhance_Linux_Security⠀⇛ In recent years, the usage of linux operating systems has increased a bit. Though, not at that impressive rate, there have been more users shifting towards Linux based systems. And around 50% of the internet users are running some sort of Linux flavor on their systems. There was a time when Linux users would consider themselves as the lucky souls who were not afraid of cyber-attacks or other kinds of vulnerabilities. But it is no secret that the Linux server has become one of today’s most desirable targets. The past few years have seen emerging malware strains that demonstrate new and dangerous tactics for spreading, remaining undetected on your machine – Cloud Snooper, EvilGnome just to name a couple! This post is going to elaborate you with some knowledge on how Linux servers are being targeted by malware, rootkits and other malicious attacks. And above all what are the sure shot ways to improve security of Linux systems. # § Privacy/Surveillance⠀➾ # ⚓ Devices_of_Palestinian_Human_Rights Defenders_[Cr]acked_with_NSO_Group’s Pegasus_Spyware_–_The_Citizen_Lab⠀⇛ In October 2021, the human rights non-governmental organization (NGO) Front Line Defenders (FLD) began collecting data on the suspected hacking of the devices of several Palestinians working for civil society organizations based in the West Bank. FLD shared the data they collected with the Citizen Lab and Amnesty International’s Security Lab for separate independent peer review of their initial findings. FLD’s analysis indicated that six devices belonging to six Palestinian human rights defenders were hacked with Pegasus, a spyware developed by the cyber-surveillance company NSO Group. Both the Citizen Lab and Amnesty International’s Security Lab independently confirmed these findings. Of the six individuals, three consented to be named. Of these three, two individuals are dual- nationals: one French, the other American. Further, all three work at NGOs designated “terrorist organizations” by the Israeli government in October 2021. These designations have been widely condemned internationally, including by prominent international NGOs (including Amnesty International and Human Rights Watch), governmental offices and representatives (such as Sweden’s Minister of International Development Cooperation and Humanitarian Affairs, the High Representative of the EU for Foreign Affairs and Security Policy, Ireland’s Minister of Foreign Affairs and Minister of Defence, the French Ministry of Foreign Affairs, the EU Special Representative for Human Rights, and U.S. Congressional representatives), and UN experts (such as the UN High Commissioner for Human Rights and the UN Special Rapporteur for Freedom of Association). The hacking described in this report took place prior to this designation. # ⚓ Digital_lending_and_small_borrowers! #PrivacyOfThePeople⠀⇛ In the latest post in our #PrivacyOfThePeople series, we look at the impact of the Personal Data Protection Bill, 2019 on digital lending application users. We examine both illegal and ‘legal’ lending apps and look at how the data protection bill will impact digital lending. [...] After the COVID induced lockdown, a slew of illegal digital lending apps started offering unsecured loans to desperate borrowers at exorbitant interest rates ranging from 60% to 100% with extremely short tenures of 7 to 15 days without any KYC or credit score verification. These apps also required extensive permissions to access the borrower’s phone for collecting contact information, photos, text messages, location and even battery percentage. The entire process was online and required no in-person verification.
