[13:03] -TechBytesBot/#techbytes-blog.josefsson.org | Static network config with Debian Cloud images Simon Josefsson's blog [13:03] schestowitz__[TR][13:03] schestowitz__[TR]The following commands creates a Debian VM with static network configuration without the annoying one-minute DHCP delay. The three essential cloud-init keywords are the NoCloud meta-data parameters dsmode:local, static network-interfaces setting combined with the user-data bootcmd keyword. Im using a Raptor CS Talos II ppc64el machine, so replace the image link with a genericcloud amd64 image if [13:03] schestowitz__[TR] you are using x86.

[13:03] schestowitz__[TR][13:03] schestowitz__[TR]Modern organisations have become reliant on their IT capabilities, and at the heart of that infrastructure is a growing need to store data. Be it transactional databases, file shares, or burgeoning data lakes for business analytics.
[13:03] schestowitz__[TR]Traditionally, storage needs have been catered to by big iron hardware vendors, but over the last decade, more and more organisations have turned to open-source solutions such as Ceph running on commodity hardware. In this post we will introduce Ceph, and some of the reasons why organisations choose it.

[13:10] schestowitz__[TR][13:10] schestowitz__[TR]Robotic additive manufacturing, sometimes called robot 3D printing, is evolving from research to applied technology with maturation of methodologies (gantry systems and robot arms) and source materials (metal powder, wire, polymer and concrete).
[13:10] schestowitz__[TR]A conventional gantry system that layers material via a single x-y plane tool path is an established 3D printing solution for certain repeatable applications, while robotic arms can offer more complexity when layering material in multiple planes. However, to date traditional approaches for planning trajectories for 3D printing are not optimized for taking advantage of high degree of freedom (DOF) [13:10] schestowitz__[TR] systems that include industrial manipulators.

[13:18] -TechBytesBot/#techbytes-blog.jimmac.eu | New Alert Sounds - Even a Stopped Clock [13:18] schestowitz__[TR][13:18] schestowitz__[TR]Sounds created for GNOME 43 were generated on a mini-computer called Teensy (currently unavailable due to the global chip shortage), running software called Dirtywave Headless written by Timothy Lamb. The software includes other synthesizer engines, but majority of the sounds were made using the 4 operator FM engine. To further complicate things, my favorite algorithm is No.16 where all of the 4 [13:18] schestowitz__[TR] oscillators are carriers, effectively being equivalent to a 4 oscillator analog synth.

[13:18] schestowitz__[TR][13:18] schestowitz__[TR]The C and C++ languages offer little protection against programmer errors. Errors do not always show up where you expect. You can silently corrupt the content of your memory. It can make bugs difficult to track. To solve this problem, I am a big fan of programming in C and C++ using sanitizers. They slow your program, but the check that memory accesses are safe, for example.

[13:22] schestowitz__[TR][13:22] schestowitz__[TR]In previous blog posts there was some talk about implementing a simple system that generates books (both PDF and ebook) from plain text input files. The main question for that is what the input format should be. Currently there are basically two established formats: LaTeX and Markdown. The former is especially good if the book has a lot of figures, cross references, indexes and all that. The latter is [13:22] schestowitz__[TR] commonly used in most modern web systems but it is more suitable to specifying text in the "web page" style as opposed to "split aesthetically over pages".
[13:22] schestowitz__[TR]The obvious solution when faced with this issue is to design your own file format that fits your needs perfectly. I did not do that, but instead I did think about the issue and did some research and thinking. This is the outcome of that. It is not a finished product, you can think of instead as a grouping of unrelated things and design requirements that you'd need to deal with when creating such a [13:22] schestowitz__[TR] file format.

[13:40] -TechBytesBot/#techbytes-blog.josefsson.org | Towards pluggable GSS-API modules Simon Josefsson's blog [13:40] schestowitz__[TR][13:40] schestowitz__[TR]When an application or library is packaged for a GNU/Linux distribution, a choice is made which GSS-API library to link with. I believe this leads to two problematic consequences: 1) it is difficult for end-users to chose between Kerberos implementation, and 2) dependency bloat for non-Kerberos users. Lets discuss these separately.

[14:18] schestowitz__[TR][14:18] schestowitz__[TR]Aeon unveiled yesterday their first outdoor autonomous robot controller based on 11th Gen Core/Celeron processors from Intel. The company claims that the latency of the RBX-I2000 has been reduced to ~20 nanoseconds compared to the 100 200 microseconds found in other similar devices.
[14:18] schestowitz__[TR]The processors supported by RBX-I2000 are shown below. These Intel Core processors are also found on the COM modules that Aaeon released a couple of months ago.
