It concerns patent quality again and thus - inter alia - it concerns European_software_patents. It is no secret that Benoît_Battistelli and António_Campinos are well aware that they illegally grant patents for_the_sole_purpose_of_making_and_gambling with_more_money. There's paper trail for all this. Yesterday the Central Staff Committee said to staff: Dear Colleagues, The Directorate Quality Audit consists of examiners and formalities officers. DQA samples patent applications at grant or search stage from the Patent Workbench for quality audit. The auditors perform the checks and send the outcome by email to the competent Examining Division. The outcome is sent to the Examining Division both if the audit criteria are met and if deficiencies are found. On 11 December 2023, the three Vice-Presidents of DG1, DG4 and DG5 issued Internal Procedural Instructions updating the DQA workflow. The newly planned involvement of “line managers” and of the “DG1 independent review panel” is particularly worrying as they have disciplinary powers, reporting authority and play a decisive role in the career advancement of the members of Examining Division under the new career system. The new workflow is hence of highly questionable legality which jeopardizes the “three-man examining divisions”. From what we can gather, this paper of theirs is less than a day old or was published less than a day ago, disseminated through members of staff by hacking around illegal censorship by the Office (the EPO continues to not obey a court ruling successfully_challenging_this_censorship). Here's the publication from the EPO's own staff, presented in the form of HTML, plain text, and GemText. These people know the matter best: Zentraler Personalausschuss Central Staff Committee Le Comité Central du Personnel Munich, 08-02-2024 sc24009cp § Quality Audits⠀➾ What is DQA? The Directorate Quality Audit consists of examiners and formalities officers. DQA samples patent applications at grant or search stage from the Patent Workbench for quality audit. The auditors perform the checks and send the outcome by email to the competent Examining Division. The outcome is sent to the Examining Division both if the audit criteria are met and if deficiencies are found. The EPO Quality Report features statistics on the grant and search audit results. The latest from 2022 show (p. 46 and 38) 76% compliance for grants (vs. 85% target) and 82.6% compliance for searches. New DQA workflow… On 11 December 2023, the three Vice-Presidents of DG1, DG4 and DG5 issued Internal Procedural Instructions updating the DQA workflow. As of 1 January 2024: − the audit report, both in grant and search audits, is sent also to the line_manager of the first member of the competent Examining Division, − in case of deficiencies, a new “audit dialogue” takes place involving also the line_manager of the first member, − if no agreement is reached DQA may review each disagreed product finding internally, either by a “simplified review” of two auditors or a “full review” additionally comprising the quality_audit_line manager − if DQA maintains at least one finding after a full review, it informs a new “DG1_independent_review_panel” which shall issue a recommendation to the division and send a revision task to the first member “to correct the action as appropriate”. … in breach of the EPC Examiners are first and foremost bound to the European Patent Convention (EPC)1. The EPC defines that examination of European patent applications is the sole responsibility of Examining Divisions2. Such divisions shall consist of three technically qualified members, and can, only in exceptional cases, be enlarged by decision of the responsible Examining Division with a legally qualified member to four members3. There is no provision for the involvement of anyone else. This de facto excludes “DQA auditors”, “line managers”, the “quality audit line manager” and the “DG1 independent review panel”. Should they be involved according to the new DQA workflow, the applicable rules on the composition of the Examining Divisions are systematically violated.4 The planned involvement of “line managers” and of the “DG1 independent review panel” is ______ 1 e.g. T 0162/82, headnote; or T 0500/00, cons. 2.6.1 2 Article 18(1) EPC 3 Article 18(2) EPC 4 In fact, it is undisputed that the final decision to grant a patent or refuse a patent application remains the sole competence of the Examining Division and that neither a line manager nor anybody else can replace a member of the Examining Division when taking a decision under the EPC unless being appointed as member of the Examining Division in accordance with Article 18(2) EPC. ===================================================================== particularly worrying as they have disciplinary powers, reporting authority and play a decisive role in the career advancement of the members of Examining Division under the new career system5. Moreover, the “DG1 independent review panel” is presented internally as if it were a higher legal instance for reviewing the Examining Divisions’ decisions, besides the EPO Boards of Appeal, although it has no basis in the EPC at all. The expectations of the users of the patent system In the course of the revision of the EPC to EPC20006, the users of the European Patent System as represented by the members of SACEPO7 unanimously supported the “retention of the three-man examining divisions”. This composition of the Examining Divisions should ensure the high quality and legal certainty of the granted patents, presuming that the Divisions’ members have the required time and independence in substance for arriving at their decisions. However, the new DQA workflow obviously undermines these principles and user expectations. The “DG1 independent review panel” even has the power to send a decision back to the entrusted examiner of the competent Examining Division for “correcting” the decision “as appropriate” taking into account the panel’s recommendation without disclosing any interference to the public8. Twenty years after the EPC2000 reform, major users of the EPO patent system currently ask that the EPO focuses on substantive quality of patents by giving the necessary time to Examining Divisions 9 . These users never asked for new processes of highly questionable legality which jeopardize the “three-man examining divisions”. Conclusion The President and DG5 would be well advised to reassess the legal situation and to make the respective legal opinions on the DQA workflow available. The users of the patent system and the public deserve to be transparently informed of the EPO’s new processes. In the past, we have already requested the President to publish the respective internal EPO guidelines10 on the work in the Divisions. Now, we request that the new DQA workflow is also published and submitted to SACEPO for consultation. In case of questions or comments concerning the work in the Examining Divisions and the DQA workflow, please contact your Staff Representation. The Central Staff Committee ____ 5 A career system based primarily on incentives for examiners to achieve ever increasing productivity targets to allegedly guarantee the financial stability of the office. 6 see CA/PL 2/99, item I.A. 7 Standing Advisory Committee before the European Patent Office, “a group of 180 engaged, active and vocal user representatives from all over the world”, see also the SACEPO website 8 Only the names of the members of the competent Examining Division continue to be displayed to the public on the decision to grant without any trace in the public part of the examination file. This violates the findings of the Boards of Appeal that the person signing a communication or decision takes unconditional responsibility for its content. (OJ EPO SE 2/2021, p. 37, T 989/19) 9 “50 years EPC: The EPO ignoring the skilled person”, CSC paper (sc24001cp), 19-01-2024 “50 years EPC: The EPO ignoring the skilled person”, CSC paper (sc24001cp), 19-01-2024 10 see CSC letter sc20184cl (not published) As we are going to show in a later article, the atmosphere at the Office is again deteriorating, along with quality and compliance. The EPO is basically operating outside the rule of law while relying on crooked kangaroo (and evidently_anti-European) courts to let the matter be... and persist. This has become a serious reputation problem for the EU, which is only belatedly catching_up_with_the_problem_of_patents_on_seeds/plants. Unless the EU wakes up and gets this matter under control, all_this_corruption will_continue_to_spill_over. This is really terrible for Europe. █ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣀⡀⣘⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣦⣀⣀⣀⣀⣀⣀⣀⣀⣀⣀⣀⣀⣀⣀⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣠⣿⡿⠛⢄⣙⣿⣷⣟⢳⡾⠁⠀⠀⠈⠁⠈⣿⣿⣿⠀⢈⣿⣿ ⠀⠀⠀⠀⠀⠐⠀⠐⠀⣜⠇⣼⢧⣿⡟⠻⢿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠁⠙⠉⠙⠉⠛⠁⠛⠛⠛⠉⠋⠙⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣰⣿⣟⠁⢿⣦⣿⣿⢯⣡⡞⠁⠀⠀⠀⠀⠰⣼⣿⣿⣿⠀⠀⣿⣿ ⠀⠤⠀⠶⠄⠶⠄⠶⠄⠿⠆⠿⣾⣿⡧⠤⠬⠿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣤⠀⠀⠀⠀⠀⡄⢀⡀⢀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣀⢀⣼⣿⣏⣤⣽⣶⣿⣿⣿⣦⡟⠀⠀⠀⠀⠀⠀⣼⣿⣿⣿⣿⠀⠀⣇⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⡄⢳⣿⣿⣧⠀⠀⠀⠈⠻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣾⣿⢻⣷⣌⡿⣿⣿⠙⣶⠏⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⠀⠀⣿⣿ ⠀⣀⡀⣀⡀⢀⠀⠀⠀⠀⠃⣸⣿⣿⣿⠀⠀⠀⠀⠀⠈⠻⣿⣿⣿⣿⣿⣿⠟⣡⣾⠯⣿⣿⣧⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣠⣿⣿⢁⡘⢿⣿⣿⣿⣤⣴⠋⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⠀⠀⣿⣿ ⠓⠻⠟⠿⠟⠻⠟⠻⠛⠻⠇⠻⠿⠿⠿⠀⠀⠀⠀⠀⠀⠀⠙⢿⣿⣿⣿⢹⣿⣿⣿⠟⣽⣿⣿⣿⣦⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣰⣿⡟⣩⣉⣻⣿⣿⡟⢿⡿⠃⠀⠀⠀⠀⠀⠀⠀⠀⠀⢹⣿⣿⣿⣿⠀⠀⣿⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠙⣿⣿⣦⣵⢛⣵⣆⢙⣡⠟⣿⣿⣿⣦⡀⠀⠀⠀⠀⠀⠀⠀⣼⣿⡟⠣⣘⣿⣿⣿⡛⣿⡿⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢸⣿⣿⣿⣿⡇⠀⣿⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠄⠀⠀⠀⠀⠀⠀⠀⠀⠈⠻⣿⣿⣿⠟⣡⠟⡡⢊⡤⣸⣿⣿⣷⣄⠀⠀⠀⠀⢀⣾⣿⡛⠛⢶⣼⣿⡿⣉⣡⡟⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠠⣿⣿⣿⣿⡇⠀⢿⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠻⣿⣿⣥⢊⣴⠏⢜⡭⢂⡽⢿⣿⣷⣄⠀⣠⣿⡿⠻⢿⣶⣾⣻⢿⣦⣼⠏⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⡇⠀⢸⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠘⢿⣿⣿⣧⡶⢛⡴⠋⢴⣿⣿⣿⣿⣷⣿⣿⡀⢷⣶⣟⣿⢿⣦⣼⠏⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⡇⠀⢹⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠙⢿⣿⣶⡋⢼⣿⣶⣿⡟⣡⡝⣿⣿⣯⣙⣶⣿⡿⠿⢀⡿⠃⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⡇⠀⢸⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠙⣿⣿⣦⣿⠟⣿⡇⣿⡷⢋⣙⢿⣿⣿⣿⠙⣶⡿⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⡇⠀⢸⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠻⣿⣿⣌⣛⡴⢋⣴⣿⣧⠞⡙⢿⣿⣴⡟⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠆⣿⣿⣿⣿⡇⠀⢸⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠻⣿⣿⡗⠿⣻⠟⡁⢾⣿⠞⢻⣿⣷⣄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠂⣿⣿⣿⣿⣿⡇⠀⢸⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣼⣿⢿⣿⣿⡙⢾⣿⠟⡡⣠⠟⣩⠿⣿⣦⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⡇⠀⢘⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣾⣿⣏⠸⣿⣿⣿⣾⣫⡾⠁⣡⠞⢡⣶⣜⣿⣿⣦⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⡇⠀⠀⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣠⣿⣿⠡⣬⣵⣾⣿⠿⣿⣿⣧⡞⣵⣶⣬⣿⡿⢋⡙⢿⣷⣄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⡇⠀⠀⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣰⣿⡟⢛⢦⣽⣿⣿⣯⠱⣾⡿⣿⣿⣬⣿⣿⣏⣴⡿⢃⡼⠿⢿⣷⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠋⣿⣿⣿⣿⣇⠀⠀⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣼⣿⣿⣄⡛⣿⣿⣟⠣⣤⣼⠏⠀⠈⢻⣿⣿⣟⢿⣿⣴⢋⣴⡿⢈⣿⣿⣦⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⠀⠀⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣾⣿⠏⣼⣿⣿⣿⣟⡛⢁⣿⠋⠀⠀⠀⠀⠙⢿⣿⣿⡟⣿⣿⣏⣴⣿⠟⢉⣿⣷⣄⠀⠀⠀⠀⠀⠀⠀⢠⣿⣿⣿⣿⣿⠀⠀⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠⣿⣿⠋⠢⣍⣯⣿⣿⡿⣿⡿⠃⠀⠀⠀⠀⠀⠀⠀⠙⢿⣿⣮⣿⣿⣿⣡⢠⠞⢋⠿⢿⣷⣄⠀⠀⠀⠀⠀⢸⣿⣿⣿⣿⣿⠀⠀⣿ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣰⣿⡿⠻⢷⣵⣾⣟⠣⣌⣴⡟⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠻⣿⣿⣿⣿⣿⣧⡞⣡⣶⠎⣻⣿⣦⡀⠀⠀⠀⢸⣿⣿⣿⣿⣿⠀⠀⣿ ⢄⣀⣀⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣴⣿⣿⡓⢤⣱⣾⣿⡙⢷⣾⡟⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠻⣿⣷⣽⢿⣿⣿⣧⣾⠟⣹⣿⣿⣦⠀⠀⣿⣿⣿⣿⣿⣿⠀⠀⢿ ⠀⠀⠀⠉⠉⠛⠒⠶⢤⣤⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣾⣿⠏⣭⡙⣶⣿⡻⢬⣹⣿⠏⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠻⣿⣦⣽⣿⣿⣥⣾⣿⡿⢻⣿⣷⣤⣿⣿⣿⣿⣿⣿⠀⠀⢸ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠁⠀⠰⠴⠂⠀⠀⠀⠀⠀⠀⠠⠀⠀⢠⣾⡿⠿⢦⣙⢿⣿⣯⡙⣲⣿⠋⠀⠀⠀⠀⠀⢠⣤⣶⣆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠙⢿⣿⣧⣿⣿⣿⣇⣴⣿⣿⢿⣿⣿⣿⣿⣿⣿⣿⠀⠀⢸ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⠀⠀⠀⠀⠀⠀⠀⠄⢀⡀⣠⣿⣿⣇⠺⣾⣿⡿⢦⡙⣿⡿⠃⠀⠀⠀⠀⠀⠀⢸⣿⣿⣿⣷⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠙⢿⣿⣿⠙⢿⣻⡟⠡⣾⠿⣿⣿⣿⣿⣿⣿⠀⠀⢺ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠁⠀⠀⠀⠀⠀⠀⠀⠀⣸⣿⣿⣿⣿⣷⣾⡟⠿⠆⣿⡿⠁⠀⠀⠀⠀⠀⠀⠀⢸⣿⣿⣿⣿⣿⣦⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠹⣿⣷⣞⣱⣿⢦⣴⠞⣩⣾⢻⣿⣿⣿⠀⠀⢸ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣼⣿⣿⣿⣿⣿⣿⣿⣿⣷⣾⠟⠀⠀⠀⠀⠀⠀⠀⠀⠈⢸⣿⣿⣿⣿⣿⣿⣿⣦⡄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠻⣿⣿⣇⡝⢵⣾⠟⣡⠟⣭⢻⣿⠀⠀⢸ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠟⠲⢤⣀⠀⠀⠀⠀⠀⠀⠀⢸⣿⣿⣿⣿⣿⣿⣿⣿⣿⣶⣀⣀⠀⠀⢀⠀⠀⠀⠀⠀⠈⠻⣿⣧⣈⣡⣿⣿⢀⣿⡼⡛⢧⠀⢸ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠃⠀⠀⠀⠈⠙⠶⣄⡀⠀⠀⠀⣽⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣤⣀⣄⡀⠀⠀⠀⠀⢴⡿⢿⣿⣧⡸⢟⣼⣿⣾⣿⣸⣇⢸ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⡀⡀⠀⠀⠀⣰⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡟⠁⠀⠀⠀⠀⠀⠀⣰⡇⠉⠓⢤⣉⢹⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⠀⠀⠀⠀⢸⡇⠸⣿⣿⣿⣏⠹⠿⣿⣿⣿⡿⠐ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣼⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠏⠀⠀⠀⠀⠀⠀⠀⣠⣿⡇⠀⠀⠀⠈⢻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⠀⠀⠀⠀⢸⣇⠀⣿⣺⣿⣿⣷⣾⣿⣿⣿⠁⠸ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠋⠀⠀⠀⠀⠀⠀⠀⢰⣿⣿⡇⠀⠀⠀⠀⠈⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⠀⠀⠀⠀⢨⣿⠀⢿⣿⣿⣿⣿⣿⣿⣿⡇⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠁⠀⠀⠀⠀⠀⠀⠀⢠⣿⣿⣿⡇⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⠀⠀⠀⠀⠀⣿⠀⢸⣿⣿⣿⣿⣿⣿⣿⡇⠀⠀ ䷩ 𝚕𝚒𝚗𝚎 383 ╒═══════════════════ 𝐀𝐑𝐓𝐈𝐂𝐋𝐄 ═════════════════════════════════════════════════╕ (ℹ) Images, hyperlinks and comments at https://news.techrights.org/n/2024/02/09/Even_the_Doas_Camp_is_Unhappy_About_What_Microsoft_Does_to_Sudo.shtml Gemini version at gemini://gemini.techrights.org/n/2024/02/09/Even_the_Doas_Camp_is_Unhappy_About_What_Microsoft_Does_to_Sudo.gmi ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ Even the Doas Camp is Unhappy About What Microsoft Does to Sudo⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ posted by Roy Schestowitz on Feb 09, 2024 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Theo_de_Raadt⦈_ Yes, Theo de Raadt's opinionated words elucidate the issue with some tongue-in- cheek sarcastic message After the leadership of OpenBSD let Microsoft do this to OpenSSH (because Microsoft_had_paid) we see quite a change of tune. So a reader has informed us that even Theo de Raadt (OpenBSD) noted Microsoft's latest_embrace,_extend,_extinguish_attack. As noted in the sister site: "the real story is, Microsoft copied sudo when it made UAC nearly 2 decades ago and then had the audacity to seek software patents on it." This is well documented. Many don't know or do not remember. And now Microsoft misuses the name "sudo" (in effect 'Googlebombing' it) while Michael Larabel uses the hostile move for openwashing of Windows and Microsoft (we'll omit the Phoronix link or 'spin' here). Here is what de Raadt wrote last night: List: openbsd-tech Subject: Introducing Word for OpenBSD From: "Theo de Raadt" Date: 2024-02-08 21:39:05 Message-ID: 83808.1707428345 () cvs ! openbsd ! org [Download RAW message or body] In the spirit of Microsoft bringing sudo to Windows, it is time we bring Word to OpenBSD. Same as Microsoft: 1. Not caring about name confusion 2. Not caring about compatible behaviours 3. Not caring about trademarks or defacto trademarks 4. Not asking the original product teams if it is OK. This is setting the standard as well as Microsoft will do with sudo.

Patent Office (EPO) is Broken, Laws Cease to Apply⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ posted by Roy Schestowitz on Feb 09, 2024 A new leaked publication LESS than a day ago the Central Staff Committee (CSC) at the EPO circulated information about a meeting which took place on the last day of January, describing the atmosphere of that online 'meeting' as "abysmal". The message disseminated to staff said: Dear Colleagues, The General Consultative Committee (GCC) met by videoconference on 31 January 2024 with only one item on the agenda: - General Guidelines on Rewards 2024 – for consultation GCC/DOC 01/ 2024 The Chair repeatedly interrupted our interventions by complaining that they were too long although they were concise enough to fit in the limited 45-minute timeframe planned and were no longer than the interventions made by the administration. The atmosphere was abysmal due to the Chair's strategy to destabilize our speakers and stifle staff concerns. We cannot think of a worse start of the year in terms of social dialogue. Read more in this report and our opinion on the Guidelines on Rewards 2024. So there are two components to this communication. First is the issue they wished to bring up and their formalised_opinion_on_it. It is 37 pages in total and EPO management limited the discussion to a "45-minute timeframe" - i.e. the usual tactics. They're not genuinely interested in dialogue and matters of law. As the meeting report shows, the management was rude and disruptive. Here is a full reproduction of the report: Zentraler Personalausschuss Central Staff Committee Le Comité Central du Personnel Munich, 08-02-2024 sc24008cp § Report on the GCC meeting of 31 January 2024⠀➾ An abysmal atmosphere for the first meeting of the year The General Consultative Committee (GCC) met by videoconference on 31 January 2024 with only one item on the agenda: • General Guidelines on Rewards 2024 – for consultation GCC/DOC 01/ 2024 The GCC is meant to be the highest consultation body in the EPO composed of 10 management representatives and 10 staff representatives. The meeting was chaired by Mr Ernst (VP5) following the delegation of authority from Mr Campinos. Ms Simon (VP4), although connected to the meeting, neither switched on her camera nor took the floor. Guidelines on Rewards This GCC meeting was the last in this capacity for the Director Employee Policies transferred to other duties and not in charge of the Guidelines on Rewards anymore. We expressed a kind farewell statement to him, but the Chair interrupted our statement which he considered as being ironical although it left no doubt as to its sincerity. We addressed the increasing number of staff whose performance is unduly considered to be “not met”. The Chair interrupted our intervention and pretended that it is off the topic as “appraisals have nothing to do with the rewards exercise” (sic!). Even if the Office states that there is no automatic link between the two, appraisals shall remain the basis for the rewards exercise. We questioned the lack of transparency on functional allowances since the administration removed the item from the Guidelines on Rewards. The Chair did not allow us to finish our intervention and deemed it off-topic. The Chair repeatedly interrupted our interventions by complaining that they were too long although they were concise enough to fit in the limited 45-minute timeframe planned and were no longer than the interventions made by the administration. Any other business We asked to comment on the appointment announced on 25 January 2024 of the new Director of Talent Planning and Architecture in charge of performance management and rewards. The Chair considered our intervention as irreceivable, refused to record it in the minutes and deterred us by stating that such an intervention would not be allowed in the future if we make any reference to its content in our report on the GCC. The atmosphere was abysmal due to the Chair's strategy to destabilize our speakers and stifle staff concerns. We cannot think of a worse start of the year in terms of social dialogue. The Central Staff Committee We recently (middle of last month) learned from an EPO insider that the atmosphere in the Office is more or less back to the "Battistelli times". Will there be strikes and protests later this year? And, if so, will politicians bother to listen or take action? All this inaction works in favour of additional_corruption. Crime becomes "normalised" or "the standard" if people includingg elected officials refuse to do anything about it. █ ䷩ 𝚕𝚒𝚗𝚎 682 ╒═══════════════════ 𝐀𝐑𝐓𝐈𝐂𝐋𝐄 ═════════════════════════════════════════════════╕ (ℹ) Images, hyperlinks and comments at https://news.techrights.org/n/2024/02/09/IRC_Proceedings_Thursday_February_08_2024.shtml Gemini version at gemini://gemini.techrights.org/n/2024/02/09/IRC_Proceedings_Thursday_February_08_2024.gmi ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ IRC Proceedings: Thursday, February 08, 2024⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ posted by Roy Schestowitz on Feb 09, 2024 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Small_Crimes:_Posters_on_billboard⦈_ 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇GN 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇GNOME_Gedit⦈_ #techrights_log #boycottnovell_log 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇GN 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇GNOME_Gedit⦈_ #boycottnovell-social_log #techbytes_log =============================================================================== The corresponding text-only bulletins for_Tux_Machines and for_Techrights contain all the text.

Elsewhere⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ posted by Roy Schestowitz on Feb 09, 2024, updated Feb 09, 2024 The buzzwords shuffle (for computer_programs or algorithms, which are reducible to maths and are hence immaterial): 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇'Software', 'Hey Hi', '4IR', 'robotics', 'automation', 'CII'⦈ THIS month we should be able to cover EPO_affairs every day. This topic is highly relevant to us not just because of the "rights" aspect but also because of software_patents, which are not compatible with Software Freedom. Dr. Richard_Stallman_said_this_when_Linux_(the_kernel)_was_just_starting. What's at stake with software patents? Well, a lot actually. We're also learning that EPO examiners really dislike such patents and antagonise them as well - if not best - as they can (without getting sacked). Oligarchs are trying to ban the trade (coding) or restrict people's access to - or mere creation of - tools, instruments etc. such that they will always remain beholden to oligarchs with "tech giants" and "warchest" of patents or "patent portfolio" (the euphemism du jour for monopoly). They are, in essence, trying to illegalise resistance at its very core. Cory Doctorow's latest_article_ (dated_8_Feb._2024) is entitled "Big Tech disrupted disruption". We certainly hope that the patent examiners in the EPO and elsewhere (there are tens of thousands of them in the world) will join our resistance to patents on algorithms, at some level/capacity at least. Such patents need to be eradicated for society's sake. There's lots of discussion lately about tech regulation (usually framed in the context of buzzwords like "HEY HI" or "AI"), but why are patents not brought up? Are most politicians out there bought and paid for? "Furious examiner" recently wrote to us, expressing appreciation. "Many thanks for the work you do and for providing the world outside the EPO with important information," the examiner said. "The news about lifting the immunity of international organisation it's of the utmost importance. Many suicides within the office weren't elucidated. Apparently, the office management made [sic] pressure on the partners to "invite" them not to ask many questions. Fortunately, some colleagues harassed by the office gained visibility, like the Irish judge, and were so better protected. But what about other anonymous victims? Have a nice day." Benoît_Battistelli has plenty of blood on his hands and he's still alive, preying on some other people while hiding from or ducking authorities when new scandals_emerge. António_Campinos is openly promoting software patents (we did detailed rebuttals to his awful talks about it in past years) and he needs to go, along_with_his_corrupt_acolyte_in_the_EU. One can only hope that MEPs are paying attention to this growing reputation problem. Maybe they will even do something about it, starting with the_European_Space_Agency. As I never worked for any of these institutions, not even indirectly, I have no stake in the outcome except as an independent programmer. Please, EPO insiders, help_us_squash_software_patents_for_good. █ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣀⡀⢀⠀⠀⠠⠤⡤⠤⠤⠤⠤⣤⣤⣶⣶⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣯⣭⣤⣤⣴⣒⣀⠠⣀⣀⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Yes, it is. That's impossible.⦈ If this "clown computing" thing is the future of Microsoft, then there's trouble ahead. The company's debt_is_growing. Buying one's own shares of buying other companies' revenues isn't really growth. "Microsoft, the world’s most valuable company, declared a profit of $4.5 billion in 1998; when the cost of options awarded that year, plus the change in the value of outstanding options, is deducted, the firm made a loss of $18 billion, according to Smithers." --The_Economist,_1999 ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿

Technology and Science Issues⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ posted by Roy Schestowitz on Feb 09, 2024 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Soylent_News⦈_ And the aggressive,_aggravating_trolling_against_the_site is somewhat of a sign that it has become effective as a community, not just as a site THIS past half a year I've followed Soylent_News closely, seeing that it effectively abandoned_Twitter_last_summer (good move, their Atom and RSS feeds cannot be throttled or censored by Musk and his buddies) and there were many kinds of social attacks on people who led the site. In recent days we mentioned the culprits in passing. It is fascinating to see the pattern of abuse against volunteers in a "volunteer-powered news aggregation on technology, science, and general interest with public discussion and powerful comment moderation." They joined Twitter in February 2014 (yes, the site is 10 now) and have since then transitioned to an ad hoc community-centric management structure. They don't sell out. They don't push ads or "sponsored" crap. One main contributor (on the editorial side) is nowadays "janrinok", who has been constructive, productive and mostly amicable in IRC. If our readers are looking for a good site to follow, have a look at Soylent News. Be sure to identity and then ignore trolls/provocateurs. Those sort of bad faith actors ruined the original Slashdot, but they won't ruin Soylent News as long as its big community is supportive. █ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡯⠀⠀⠀⠙⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠛⠻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡯⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡯⠀⠀⠀⠀⠀⠀⡤⠤⠀⣠⢤⡀⢠⠀⢠⠀⡄⠀⠀⡤⠤⠀⡄⠀⡄⠠⣤⡤⠀⠀⠀⠀⢹⡇⢠⣿⠀⣀⣀⡇⠀⡟⠙⡿⠀⣿⠁⣀⣸⣷⣀⣀⣸⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡯⠀⠀⠀⠀⠀⠀⣧⡀⢠⠇⠀⢹⠀⢧⡎⠀⡇⠀⠀⣇⡀⠀⡟⡄⡇⠀⢸⠀⠀⠀⠀⠀⠀⠇⢸⡏⠀⠛⢻⡇⢰⠃⠀⠇⢰⣿⠀⠻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣯⠀⠀⠀⠀⠀⠀⠀⢹⠈⡆⠀⡼⠀⢸⠀⠀⡇⠀⠀⡇⠀⠀⡇⠹⡇⠀⢸⠀⠀⠀⠀⢰⡆⠀⣼⡇⢰⣶⣿⡇⠀⢰⠀⠀⣾⣿⣷⠀⢹⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣗⠀⠀⠀⠀⠀⠀⠛⠋⠀⠙⠛⠁⠀⠘⠀⠀⠛⠛⠀⠛⠛⠀⠃⠀⠃⠀⠘⠀⠀⠀⠀⢸⣧⠀⣿⠁⠈⠉⣿⡇⠀⣾⠀⢰⣿⡃⠉⢀⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣗⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣼⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣀⣀⣠⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣶⣾⣿⣿⣿⣿⣿⡏⠙⢻⡟⡻⠟⠻⡛⠟⠻⠹⠛⠋⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣧⣶⣴⣦⣼⣇⣴⣦⣶⣴⣤⣴⣴⣤⣦⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ䷩ 𝚕𝚒𝚗𝚎 7384 ╒═══════════════════ 𝐀𝐑𝐓𝐈𝐂𝐋𝐄 ═════════════════════════════════════════════════╕ (ℹ) Images, hyperlinks and comments at https://news.techrights.org/n/2024/02/09/Thanking_Readers_and_Volunteers_for_the_Support.shtml Gemini version at gemini://gemini.techrights.org/n/2024/02/09/Thanking_Readers_and_Volunteers_for_the_Support.gmi ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ Thanking Readers and Volunteers for the Support⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ posted by Roy Schestowitz on Feb 09, 2024 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Man_and_woman_holding_hands_by_fingers_with_anchor_tattoo⦈_ THE sister site is turning_20_exactly_4_months_from_now and Techrights will turn 20 in 2026. Since 2014 our foremost focus has been the EPO, whereas in the site's earlier years the focus was Novell, which was in turn connected to Microsoft. Our community grew in recent years (we wrote about it last week) and the site has become more robust to censorship, which means it can more easily publish suppressed information from EPO insiders and all sorts of whistleblowers. We have secure and encrypted communication channels and there are people who help run the site 24/7. The same goes for our Soylent_News_friends. It's Friday night here in the UK and I've exhausted all the news links at 4PM, which is unusually early. Sign of how dead news sites have become! I used to have to "play catchup" until Saturday evening (to fully check Friday's news) and now it's all done by Friday afternoon. This gives us more leeway and more time to do research, typically leading up to exclusive and original material. As noted moments_ago, eradicating software_patents remains a key goal, which is very much related to what birthed this site (the patent collusion of Novell and Microsoft) and is also connected to Software Freedom. We still have plenty of unpublished material to go through and verify. This year will be busy and fruitful. Behind the scenes many people work hard and take risks, especially whistleblowers, who rarely receive appreciation because their identities are unknown to the public. █ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠃⠂⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢸⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣴ ⣆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣏⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠛ ⣿⣦⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡇⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠ ⣿⣿⣧⠀⠀⠀⠀⠀⠀⠀⠀⠀⠘⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠋⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⡀⠀⠀⠀⣰⣿ ⣿⣿⣿⣧⡀⠀⠀⠀⠀⠀⠀⠀⠀⠘⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠋⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣴⣿⣿⣶⣾⣿⣿ ⣿⣿⣿⣿⣷⡄⠀⠀⠀⠀⠀⠀⠀⠀⠈⢻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠋⠁⠀⠀⠐⠂⠀⠀⠀⠀⠀⠀⠀⠀⠀⣼⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⡄⠀⠀⠀⠀⠀⠀⠀⠀⠀⢻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠟⠋⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⡄⠀⠀⠀⠀⠀⠀⠀⣰⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠛⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢸⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⡄⠀⠀⠀⠀⠀⠀⠘⠿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠋⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠠⠄⠀⠀⠀⠀⠀⠀⠀⠀⣸⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣄⠀⠀⠀⠀⠀⠀⠀⠈⠙⠛⠻⢿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⡄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠉⠛⠿⠻⠿⠟⠻⠿⠀⠀⠙⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⠏⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣶⣄⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠙⠉⠻⠿⠿⠟⢿⣿⣿⣿⡏⠙⠁⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣠⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠈⠀⠀⠀⠀⠀⠀⢀⣀⣀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣼⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢀⣀⣀⡀⠀⠀⠀⠀⢠⣤⣶⣿⣿⣿⣆⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣠⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣦⣄⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⢠⠀⠀⠀⠀⠀⢾⣿⣿⣿⡟⠀⠀⠀⠀⠀⢿⣿⣿⣿⣿⣿⣧⣀⣀⠀⠀⠀⠀⠀⠀⠀⢀⣼⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣧⠀⠀⠀⠀⠀⠀⠀⠀⠀⠸⠀⠀⠀⠀⠀⠸⣿⣿⣿⡇⠀⠀⠀⠀⠀⠸⣿⣿⣿⣿⣿⣿⣿⣿⣿⡿⠀⠀⠀⠀⠀⣾⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣶⣤⡀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⣿⣿⣿⣿⡄⠀⠀⠀⠀⢸⣿⣿⣿⣿⣿⣿⣿⣿⣿⠁⠀⠀⠀⠀⣰⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣦⠀⠀⠀⠀⠀⣀⣠⣤⣤⣾⣿⣿⣿⣿⣿⣤⣤⠀⠀⣸⣿⣿⣿⣿⣿⣿⣿⣿⡏⠀⠀⠀⠀⣠⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣧⡀⠀⠀⠀⢻⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣶⣿⣿⣿⣿⣿⣿⣿⣿⣿⣧⡀⠀⠀⣰⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣷⣤⣀⣀⣼⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿⣿ ䷩ 𝚕𝚒𝚗𝚎 7463 ╒═══════════════════ 𝐃𝐀𝐈𝐋𝐘 𝐋𝐈𝐍𝐊𝐒 ═════════════════════════════════════════════╕ ⠀⌧ █▇▆▅▄▃▂▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁ Links 09/02/2024: Buzzwords, Hype, and Layoffs Still Dominate⠀▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▂▃▄▅▆▇█ ⌧ posted by Roy Schestowitz on Feb 09, 2024, updated Feb 09, 2024 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Blockchain_Topic⦈_ 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇GNOME bluefish⦈ § Contents⠀➾ * Leftovers o Science o Education o Hardware o Health/Nutrition/Agriculture o Proprietary/Artificial_Intelligence_(AI) o Security # Privacy/Surveillance o Defence/Aggression o Environment # Energy/Transportation # Wildlife/Nature o Finance o AstroTurf/Lobbying/Politics o Censorship/Free_Speech o Freedom_of_Information_/_Freedom_of_the_Press o Civil_Rights/Policing o Internet_Policy/Net_Neutrality o Digital_Restrictions_(DRM) o Monopolies/Monopsonies # Patents # Trademarks # Copyrights * § Leftovers⠀➾ o ⚓ Hackaday ☛ The_End_Of_Landlines?⠀⇛ Imagine if, somehow, telephones of all kinds had not been invented. Then, this morning, someone entered a big corporation board room and said, “We’d like to string copper wire to every home and business in the country. We’ll get easements and put the wires on poles mostly. But some of them will go underground where we will dig tunnels. Oh, and we will do it in other countries, too, and connect them with giant undersea cables!” We imagine that executive would be looking for a job by lunchtime. Yet, we built that exact system and with far less tech than we have today. But cell phones have replaced the need for copper wire to go everywhere, and now AT&T is petitioning California to let them off the hook — no pun intended — for servicing landlines. o ⚓ Hackaday ☛ A_Tube_Tester_Laid_Bare⠀⇛ There’s still a mystique around vacuum tubes long after they were rendered obsolete by solid state devices, and many continue to experiment with them. They can be bought new, but most of us still come to them through the countless old tubes that still litter our junk boxes. But how to know whether your find is any good? [Rob’s Fixit Shop] took a look at a tube tester, once a fairly ubiquitous item, but now a rare sight. o ⚓ Hackaday ☛ 3D_Printing_Silicone_Parts⠀⇛ Silicone is a useful material for many purposes. Traditionally, creating something out of silicone required injection molding. That’s not difficult, but it does require a good bit of setup. As [Formlabs] points out in a recent video, there are at least three other routes to create silicone parts that utilize 3D printing technology that might fit your application better, especially if you only need a few of a particular item. You can see the video below. o ⚓ Manuel Moreale ☛ The_great_list_of_all_the_blog_platforms⠀⇛ Pretentious title, I know. It’s obviously tongue-in-cheek but it’s at least partly what I’m gonna try to do with this post. Blogs are back. They never went anywhere but still, they’re back. Many people will—hopefully—ditch social media and start a blog in the near future. Almost as many people will ask themselves which tool/platform/ incantation they should use to start said blog. I’m gonna do my part and try to collect here all the possible alternatives. I am 100% certain that this list won’t be exhaustive but it’s a start. If you have suggestions to improve it, email me. o ⚓ Simone Silvestroni ☛ Minutes_to_Midnight_-_A_Kafkaesque_digital relationship_with_ourselves⠀⇛ The topic of this month’s IndieWeb Carnival, digital relationships, invites a lot of reflection, especially from an introvert like myself, who’s been basking in the shadow of any form of genuine online communication for a long time. As a Gen-X, I had been heavily invested in email, Usenet newsgroups, BBSes, and IRC channels during the 1990s. I used to juggle between Eudora, Forté Agent, a client called FirstClass, and some form of terminal emulation. o ⚓ Barry Hess ☛ Digital_Relationships_Offer_Real_Hope⠀⇛ Upon reflection I’ve realized that for most of my conscious life I’ve been looking to the digital for hope in this broken world. When I was in high school I wrote a research paper about the [Internet]. I wrote about the limitless potential the [Internet] had to bring people together. As a curious kid in a small, rural town, I instinctually craved connecting with other people out there in the world. Subconsciously I think I knew that there were a lot of “my people” out there, yet to be met. o ⚓ Teleport ☛ 2024_Predictions_from_Teleport_CEO_Ev_Kontsevoy⠀⇛ In 2024, I hope to see significant growth and renewed optimism in the tech sector. Personally, I’m looking forward to the year ahead with positivity as Teleport enters an important period and a packed pipeline of significant enhancements to the platform. These capabilities are increasingly critical to a threat landscape that is centered on attacking identity and exploiting human behavior. o ⚓ Nico Chilla ☛ My_website_as_a_home⠀⇛ Back in Spring 2021, I was browsing the web for an online tool that would let me generate spirograph-like vector drawings, which I was hoping to incorporate in a project. My search led me to the perfect such generator on “JW’s Pictures and Patterns Site”, the personal website of one John Whitehouse. I hope you enjoy this letter, found at the top of his home page, as much as I did: [...] o ⚓ Michael Bburkhardt ☛ Photography_Lessons_I_Learned_(The_Hard_Way) in_the_Galápagos⠀⇛ In January my wife and I spent a week with some good friends on an expedition cruise around the Galápagos Islands. The experience was far beyond anything I’d hoped for. The weather, the sea, the wildlife, even the land, was gorgeous. The photography though, did not go as I had planned. This is not your run of the mill vacation photography scenario, and I found I was ill-prepared for shooting these subjects in these conditions. In short, I learned a few lessons about photography, and myself as a photographer, the hard way. o ⚓ Hackaday ☛ Lawny_Five_Keeps_Lawn_Mowed,_Snow_Plowed⠀⇛ Although there’s been considerable excitement over the past half century of a Jetsons-like robotic future, outside of a few niche uses of our day-to-day lives there hasn’t been much in the way of robotic assistants coming to ease our physical household workloads. Sure, robots exist in manufacturing and other industrial settings, but the vast majority of us won’t see a robotic revolution unless we make it for ourselves. To that end, [Jim] has begun construction of a robot that can at least mow his lawn and eventually plow his driveway, among other potential tasks. o § Science⠀➾ # ⚓ The Register UK ☛ CERN_training_robot_dogs_to_spot radiation_hazards_at_LHC⠀⇛ And so, officials at CERN turned to a dog-like robot, which appears to be Unitree's Go1 model priced at $2,700, to carry out an inspection test to see how well that form of remote-controllable droid performs. The bot managed to complete its first radiation protection test – trotting across CERN's North Area, walking down narrow corridors and climbing stairs to examine its environment using sensors and cameras. # ⚓ Futurism ☛ Explosion_Light-Years_Away_Could_Obliterate_Life on_Earth,_Scientists_Find⠀⇛ A kilonova is usually the result of a collision involving two neutron stars within a binary system, or when a neutron star and a black hole merge. These collisions release brain-melting amounts of electromagnetic radiation in the form of gamma-ray bursts. # ⚓ Omicron Limited ☛ How_dangerous_are_kilonovae?⠀⇛ So it's hard to imagine that light years away there could be a lurking event that poses an existential threat to humanity. That threat is extremely tiny, but not zero, and it is the focus of a recent paper published in The Astrophysical Journal. o § Education⠀➾ # ⚓ Anil Dash ☛ “Wherever_you_get_your_podcasts”_is_a_radical statement⠀⇛ But here's the thing: being able to say, "wherever you get your podcasts" is a radical statement. Because what it represents is the triumph of exactly the kind of technology that's supposed to be impossible: open, empowering tech that's not owned by any one company, that can't be controlled by any one company, and that allows people to have ownership over their work and their relationship with their audience. # ⚓ Neil Selwyn ☛ Taking_technology_out_of_Swedish_schools_… and_the_search_for_what_the_‘science’_says_(notes_on_Forsler &_Guyard_2023)⠀⇛ One prominent feature of this shift has been the government’s repeated calls to follow ‘what the science says’. More specifically, this has taken the form of canvassing the opinions of Swedish neuro-scientists and cognitive psychologists around the harms of young children’s excessive device use. This fits with a general push toward ‘brain-based’ approaches in Swedish education thinking, and is seen to lend an empirical rigour to otherwise unsubstantiated claims around the educational benefits of digital technologies. o § Hardware⠀➾ # ⚓ CNX Software ☛ Sapphire_Edge+_VPR-4616-MB_mini-ITX motherboard_features_“AMD_Embedded+”_architecture_with_Ryzen R2314_&_Versal_VE2302⠀⇛ Sapphire Edge+ VPR-4616-MB is a new mini-ITX motherboard on the “new” AMD Embedded+ “architecture” comprised of an AMD Ryzen Embedded R2314 processor and an AMD Versal Hey Hi (AI) Edge VE2302 adaptive SoC (also called FPGA SoC…). # ⚓ CNX Software ☛ Microchip_introduces_PIC16F13145_Series_MCUs with_customizable_logic⠀⇛ Microchip recently introduced the PIC16F13145 series of 8-bit MCUs featuring a Configurable Logic Block (CLB). This allows users to create custom hardware-based logic functions within the MCU. This approach lowers the BOM costs and boosts performance. Last year, we saw Microchip introduce PIC32CZ Arm MCU with a Hardware Security Module (HSM) and before that, we saw they launched LAN8650/LAN8651 10BASE-T1S single-pair Ethernet Controllers. o § Health/Nutrition/Agriculture⠀➾ # ⚓ New_Claim:_20%_of_Deaths_Seem_to_Be_Connected_to_Blood Clotting_Issues⠀⇛ If we don’t get answers, vaccine hesitancy will (in general) increase and cause a lot of trouble... # ⚓ TMZ ☛ Surgical_Robot_Burned_Fatal_Hole_In_Florida_Woman, Lawsuit_Alleges⠀⇛ Her husband claims the burning of her internal organs happened without the surgical team even fully knowing what was happening at the time. # ⚓ The Beaverton ☛ Report:_One_in_20_people_are_sociopaths_and all_of_them_play_music_directly_from_their_phone_speakers_in public_settings_-_The_Beaverton⠀⇛ “Just remember,” Qundy added, “Although all sociopaths blast from their phones, not all people who blast from their phones are sociopaths. It’s important to remember that some of them are psychopaths – there’s a difference.” # ⚓ Bridge Michigan ☛ Unseasonably_warm_weather_in_Michigan_a challenge_for_fruit_farmers⠀⇛ “For the average plant in Michigan, I would say they need 1,000 chilling hours before they wake up … typically between the temperatures of 35 Fahrenheit and 45,” said Brent Crain, consumer horticulture educator at Michigan State University. If the trees are behind on chilling hours, they usually catch up in January and February because they are typically colder months, Crain said. # ⚓ New York Times ☛ More_Adolescent_Boys_Have_Eating Disorders._Two_Experts_Discuss_Why.⠀⇛ For the longest time, researchers focused on diagnosing and treating girls, but that is changing. # ⚓ Mexico News Daily ☛ Can_addiction_be_cured_with_ibogaine,_a powerful_psychedelic_used_in_Mexican_clinics?⠀⇛ Rehab facilities in Mexico are exploring treating addiction, chemical dependencies, and mental health with Tabernanthe iboga. # ⚓ The Kent Stater ☛ University_adds_cannabis_education_after statewide_legalization⠀⇛ New cannabis certificate programs are now offered at the university after last year’s election made cannabis legal across the state. The university partnered with Green Flower, an online training platform for the cannabis industry, to offer four non-credit certificate programs through its Lifelong Learning initiative. The programs focus on agriculture, business, compliance and healthcare. Prior... # ⚓ Latvia ☛ Hospital_builders_disagree_with_contract termination⠀⇛ The builder of the new Stradiņš Hospital building complex LLC "Velve" considers the hospital's decision to unilaterally terminate the contract to be illegal and continues work, the company said in a statement on February 8. # ⚓ The Straits Times ☛ Malaysia’s_health_ministry_to_take action_against_‘energy_sticks’_nasal_inhalers_sold_online⠀⇛ The product, which comes in a range of flavours, are priced as low as RM2.50. # ⚓ YLE ☛ People_in_Finland_donate_millions_of_kilos_to_UFF second-hand_stores⠀⇛ The organisation says it funded development cooperation projects in Angola, India and Mozambique last year. o § Proprietary/Artificial Intelligence (AI)⠀➾ # ⚓ New York Times ☛ Vision_Pro_Goggles_Are_Not_Safe_While Driving_a_Tesla,_U.S._Says [Ed: Nothing except driving is safe while driving]⠀⇛ Videos, many of them stunts or jokes, of people wearing Apple’s new virtual reality headset while driving Teslas in Autopilot mode prompted officials to issue warnings. # ⚓ Techdirt ☛ Congressional_Witness_Claims_ChatGPT_Won’t_Write Poems_Praising_Jim_Jordan;_Ranking_Member_Submits_A_Bunch_Of ChatGPT-Authored_Poems_Praising_Jim_Jordan⠀⇛ We’ve written a few times now about how the misleadingly named House “Subcommittee on the Weaponization of the Federal Government” is not actually looking into the “weaponization of the federal government,” but rather is very much about allowing Chairman Jim Jordan to go about weaponizing the powers of the subcommittee himself to threaten and intimidate others for their free speech. # ⚓ Digital Music News ☛ Google’s_MusicFX_Has_Created_More_Than 10_Million_Tracks⠀⇛ Google reports on the successes of its generative Hey Hi (AI) tools MusicFX and TextFX, and announces the release of ImageFX. # ⚓ Tracy Durnell ☛ If_the_medium_is_the_message,_what_do_AI graphics_say?⠀⇛ To me, using an AI-generated graphic says that the writer probably puts little value in art or aesthetics — which is fine in itself — but that also leads me to the conclusion the piece was written as “content” because the only reason to add a superfluous image is for social media share previews. Maybe the writing is good, maybe it’s not — the AI graphic is enough to make me question. Ryan Broderick describes using AI graphics as “the digital equivalent of wearing a fake Chanel bag.” # ⚓ Tedium ☛ Novell_Meets_Apple:_How_MacOS_Nearly_Went_Intel_in 1992⠀⇛ Today in Tedium: “Whatever is good for our competition is good for us” is not usually a sentiment used in the cutthroat business world, especially in a space like technology where large companies are known for brazenly ripping one another off—after all, when was the last time you logged into a social network that didn’t have a “Stories” feature? But it was a stated business model of the networking software company Novell throughout the 1980s and early 1990s, and one that inspired one of the most unusual collaborations during that era. Today’s Tedium talks about the time, way back in 1992, that Novell nearly convinced Apple to port the original MacOS to x86 in a bid to take on Windows, and why it didn’t end up happening in the end. — Ernie @ Tedium # ⚓ Mike Rockwell ☛ ‘The_Productivity_Use_Cases_Simply_Didn’t Materialize_for_Me’⠀⇛ I don’t find the Vision Pro to be compelling at all. I think of it like 3D movies or motion controls in games — something that will be popular for a period time, but will ultimately only be useful for specific applications and thought of more as a novelty than as the default. o § Security⠀➾ # § Privacy/Surveillance⠀➾ # ⚓ NL Times ☛ Police_intelligence_services_unlawfully spied_on_whole_population_groups⠀⇛ The police intelligence services unlawfully monitored entire population groups, the Supervisory Committee of the Intelligence and Security Services (CTIVD) said. In the four- month period between February 23 and July 1, 2022, they crossed that line three times, NOS reports. # ⚓ The Register UK ☛ FBI's_latest_defense_of_warrantless S._702_snooping_is_China⠀⇛ Section 702 is a contentious amendment to FISA that is supposed to allow US intelligence agencies to spy on foreign intelligence targets located overseas. In reality, the private communications of some US persons may be warrantlessly swept up in these Section 702 dragnets and analyzed by agents, which alarms privacy campaigners. The amendment is due to expire by April 19 this year unless Congress votes to reauthorize it. Lawmakers have the option of tweaking the rules so that, for instance, warrants are required in certain circumstances or some other protections are put in place. The Feds aren't a fan of some of the changes to 702 right now under consideration, as they argue things like warrant requirements for all those queries they run each month will slow down and hamper investigations. # ⚓ Gizmodo ☛ OpenAI_Wants_to_Control_Your_Computer⠀⇛ OpenAI is reportedly developing “agent software,” that will effectively take over your device and complete complex tasks on your behalf, according to The Information. OpenAI’s agent would work between multiple apps on your computer, performing clicks, cursor movements, and text typing. It’s really a new type of operating system, and it could change the way you interact with your computer altogether. # ⚓ The Verge ☛ Ring’s_cheapest_subscription_plan_is going_up_by_$1_a_month⠀⇛ Just last month, Arlo increased its single- camera subscription price to $7.99 monthly from $4.99. Google Nest’s cheapest plan went up to $8 a month from $6 late last year, but that covers all cameras on your account. On balance, Ring’s increase is small, but unlike when it raised prices in 2022 (from $2.99 to $3.99), subscribers aren’t getting any new features — just higher costs all around. Without a subscription, all you can do with a Ring camera is view a livestream and get alerts for motion from your camera. # ⚓ Vox ☛ Facebook_is_20_years_old._Here_are_some_of_the platform’s_worst_days.⠀⇛ As the Crimson noted, Zuckerberg was trying to restore his reputation on campus with TheFacebook. His previous creation was Facemash, a “Hot or Not?” clone that stole student photos from private house directories of Harvard undergraduates and asked visitors to decide which one was more physically attractive. # ⚓ Patrick Breyer ☛ Police_data_sharing:_“Prüm_II”_lacks safeguards⠀⇛ Today, MEPs approved the trilogue outcome of the regulation for automated data exchange for police cooperation (“Prüm II”). Pirate Party Members of the European Parliament voted against Prüm II, because this unprecedented rise in personal data sharing among EU police forces lacks sufficient safeguards for affected individuals. Extending the existing system to soon include facial images and police records further accelerates this trend. o § Defence/Aggression⠀➾ # ⚓ RFA ☛ North_Korea_forces_residents_to_buy_photos_of_recent satellite_rocket_launch⠀⇛ The people say both the photos and missiles are a waste. They want food instead. # ⚓ Hong Kong Free Press ☛ Violent_crime_and_fraud_surge,_as Hong_Kong’s_crime_rate_rises_29%_in_2023⠀⇛ Hong Kong logged over 90,000 reported crime cases in 2023 – a 28.9 per cent increase from a year earlier. The rise was led by a surge in fraud- related offences and violent crime, including robbery and rape, according to police data released on Tuesday. # ⚓ India Times ☛ TikTok_challenges_EU_fee_under_Digital Services_Act⠀⇛ TikTok, the Chinese social media short video platform, is the latest tech giant to fight a supervisory fee mandated by the EU under the new Digital Services Act (DSA). This fee, set at 0.05% of a company's annual worldwide net income, aims to finance the bloc's monitoring of compliance with the DSA's rules. TikTok follows Meta Platforms, which previously contested the fee. # ⚓ EFF ☛ EFF_Helps_News_Organizations_Push_Back_Against_Legal Bullying_from_Cyber_Mercenary_Group⠀⇛ We are helping to push back on that effort, which seeks to transform a very limited and preliminary Indian court ruling into a global takedown order. We are representing Techdirt and MuckRock Foundation, two of the news entities asked to remove Appin-related content from their sites. On their behalf, we challenged the assertions that the Indian court either found the Reuters reporting to be inaccurate or that the order requires any entities other than Reuters and Google to do anything. We requested a response – so far, we have received nothing. # ⚓ Meduza ☛ Finland_extends_border_closure_with_Russia_until mid-April⠀⇛ The Finnish Interior Minister added: “Understandably, the continued total closure of the eastern border is distressing especially for people with family on the Russian side. However, the temporary closure of border crossing points is the result of Russia’s actions, which require Finland to put national security first.” # ⚓ The Hill ☛ Mayor_Bowser_signs_order_outlining_AI_plan_for DC_government⠀⇛ The announcement was held at the Microsoft Innovation & Policy Center. The D.C. government uses Microsoft 365 in its work and said it is ready to use the company’s Azure AI Government Cloud in the future. The executive order is effective immediately. # ⚓ The Atlantic ☛ The_Cases_Against_Trump:_A_Guide⠀⇛ In all, Trump faces 91 felony counts across two state courts and two different federal districts, any of which could potentially produce a prison sentence. He’s also dealing with a civil suit in New York that could force drastic changes to his business empire, including closing down its operations in his home state. Meanwhile, he is the leading Republican candidate in the race to become the next president—though the Supreme Court has now heard a case seeking to disqualify him. If the criminal and civil cases unfold with any reasonable timeliness, he could be in the heat of the campaign at the same time that his legal fate is being decided. # ⚓ The Atlantic ☛ If_Russia_wins⠀⇛ Despite the twaddle from propagandists in Moscow (and a few academics in the United States), Russia’s war is not about NATO, or borders, or the balance of power. The Russian dictator Vladimir Putin intends to absorb Ukraine into a new Russian empire, and he will eradicate the Ukrainians if they refuse to accept his rule. Europe is in the midst of the largest war on the continent since Nazi panzers rolled from Norway to Greece, and the Russian invasion of Ukraine is by far the most important threat to world peace since the worst days of the Cold War.

More than 200 opposition politicians and protesters have been arrested, and the government has shut down some internet access, amid what the decision’s opponents are describing as a coup. “This is just the latest step in a string of human rights abuses,” says Amnesty International researcher Ousmane Diallo, who says Sall’s latest anti-democratic move is characteristic of an increasingly repressive regime.

For migrants like Kouassi, who face increasingly xenophobic and racist anti-immigrant policies and sentiment in Europe, the film provides an “opportunity also to express ourselves” and to share “what African people are suffering before they arrive in Europe.” Kouassi served as a script consultant for the film. # § Misinformation/Disinformation/Propaganda⠀➾ # ⚓ Cloudbooklet ☛ Meta_Labeling_Hey_Hi_(AI)_Generated Images:_Facebook,_Instagram_&_Threads⠀⇛ Learn why is Meta labeling Hey Hi (AI) Generated images on its social control media platforms, such as Instagram, Facebook (Farcebook) and also Threads. # ⚓ The Register UK ☛ US_FCC_decides_AI_robocalls_are most_definitely_illegal⠀⇛ "The [TCPA] is the primary law we have to help limit unwanted robocalls," Rosenworcel said in a statement today.

He has written that all of the information online—news, research, historical documents, opinions—has conditioned people to treat everything as evidence that directly supports their ideological positions on any subject.

Supporters of the station held an impromptu sit-in at the headquarters. # ⚓ IT Wire ☛ NBN_Co_losses_blow_out_to_$696m_for_first_half_of fiscal_2024⠀⇛ Ian Chitterer, vice-president, Moody’s Investors Service, commented: "NBN Co’s results for the first half of fiscal 2024 were marginally above our expectations with EBITDA growth of 10%. "We expect a slight improvement in NBN Co’s credit profile over the next 12 to 18 months as increasing EBITDA and operating cash flow are offset by high levels of capital spending to improve the network. "NBN Co’s available liquidity of $7.3 billion is a credit positive, as it alleviates refinancing risk related to the $5.5 billion outstanding under its Commonwealth loan maturing on 30 June 2024.” # ⚓ Internet Society ☛ The_Decade_That_Changed_The_Democratic Republic_of_Congo’s_Internet⠀⇛ A little over ten years ago, using the Internet in the Democratic Republic of the Congo (DRC) wasn’t easy. There was a lot less infrastructure, and even where it was present, the fees of intercontinental data traffic meant it was way more expensive than most people could afford. o § Freedom of Information / Freedom of the Press⠀➾ # ⚓ The Hill ☛ Julian_Assange_lawyer_submits_new_registration under_foreign_agent_law⠀⇛ Julian Assange’s lawyer submitted a new registration this week with the Justice Department’s Foreign Agents Registration Act (FARA) division for his ongoing work on behalf of the embattled Australian WikiLeaks founder. # ⚓ AntiWar ☛ A_Visit_to_Julian_Assange_in_Prison⠀⇛ In Mid-December 2023, Charles Glass, the esteemed writer, journalist, broadcaster, and publisher visited with Julian Assange, an inmate at Belmarsh Prison in the U.K. Assange has been confined there since April, 2019. [...] I encourage you to read Glass’s account of his visit with Assange. It is much more than merely the account of a visit with a person in prison, it is a representation of the Espionage Act and how it is being used by the U.S. government to silence and punish those who dare expose its wrongdoings and illegalities. Much like prison visiting rules, use of the Espionage Act is arbitrary and punitive, justice or security have nothing to do with it. We are all becoming prisoners to the whims of the gate-keepers who are using the Espionage Act to keep us ignorant and in line. With Assange’s extradition, freedom of the press, along with government accountability and a myriad of other supposed freedoms from government persecution are at stake. We will each find ourselves either the visitor or the visited if the current use of the Espionage Act is allowed to continue. Whether visitor or visited, the Espionage Act puts us all in prison. I was there with Charles Glass in that prison visiting room. Considering the stakes if Julian Assange is extradited, we all were. o § Civil Rights/Policing⠀➾ # ⚓ RFA ☛ Cambodian_activist_who_spoiled_election_ballot sentenced_to_3_years⠀⇛ Chao Veasna posted a photo of his spoiled general election ballot in July as a form of protest. o § Internet Policy/Net Neutrality⠀➾ # ⚓ Techdirt ☛ America_Tires_Of_Big_Telecom’s_Shit,_Driving Boom_In_Community-Owned_Broadband_Networks⠀⇛ For decades, frustrated towns and cities all over the country have responded to telecom market failure by building their own fiber broadband networks. Data routinely shows that not only do these networks provide faster, better, and cheaper service, the networks are generally more accountable to the public — because they’re directly owned and staffed by locals with a vested interest in the community. o § Digital Restrictions (DRM)⠀➾ # ⚓ The Verge ☛ Funimation_is_shutting_down_—_and_taking_your digital_library_with_it⠀⇛ A support page on Funimation’s website says the service will automatically transfer existing subscribers to Crunchyroll, noting that the transfer “may vary depending on your specific payment platform, subscription type and region.” But the page — unhelpfully — doesn’t say how much subscribers will have to pay following the transition, only that legacy subscribers will see a price increase. You’ll have to check your email to see how much you’ll have to pay. # ⚓ Techdirt ☛ More_Confusion_Over_Xbox_Exclusives_As_Reports Of_Game_Ports_Start_Leaking⠀⇛ I don’t know what it is or why it is, but the Xbox team just can’t seem to communicate clearly when it comes to how it’s going to handle exclusivity in games for its console. After it gobbled up several game studios and publishers, most recently Activision Blizzard, the messaging from the Xbox team about what games would be exclusives has been muddy at best. It was less than two years ago that we watched them do a full flip-flop on exclusives, going from saying that they’re not doing them, to then doing them, only to then say that long-term the company would ween itself off of exclusives because they don’t comport with the company’s “philosophy.” § Monopolies/Monopsonies⠀➾ o ⚓ The Register UK ☛ Apple_broke_web_apps_in_iOS_17_beta_and_hasn't fixed_them⠀⇛ The enforcement of Europe's Digital Markets Act was expected to change that – to promote competition held back by gatekeepers. But Apple, in a policy change critics have called "malicious compliance," appears to be putting web apps at an even greater disadvantage under the guise of compliance with European law. o ⚓ CoryDoctorow ☛ Big_Tech_disrupted_disruption⠀⇛ And yet…disruption is nowhere to be seen when it comes to the tech sector itself. Five giant companies have been running the show for more than a decade. A couple of these companies (Apple, Microsoft) are Gen-Xers, having been born in the 70s, then there's a couple of Millennials (Amazon, Google), and that one Gen-Z kid (Facebook). Big Tech shows no sign of being disrupted, despite the continuous enshittification of their core products and services. How can this be? Has Big Tech disrupted disruption itself? That's the contention of "Coopting Disruption," a new paper from two law profs: Mark Lemley (Stanford) and Matthew Wansley (Yeshiva U): [...] o ⚓ SSRN ☛ Coopting_Disruption⠀⇛ We argue that the tech giants have learned how to coopt disruption. They identify potentially disruptive technologies, use their money to influence the startups developing them, strategically dole out access to the resources the startups need to grow, and seek regulation that makes it harder for the startups to compete. When a threat emerges, they buy it off. And after they acquire a startup, they redirect its people and assets to their own innovation needs. These seemingly unrelated behaviors work together to enable the tech giants to maintain their dominance in the face of disruptive innovations. o § Patents⠀➾ # ⚓ Dennis Crouch/Patently-O ☛ Judicial_Misconduct_Sanction Against_Judge_Newman_Affirmed [Ed: Misconduct in case of patent maximalist. Good riddance?

The Committee includes seven Federal Judges from around the country, chaired by Fourth Circuit Judge Traxler. The particular finding here is an affirming the Federal Circuit’s determination that Judge Newman committed serious misconduct by refusing to undergo a requested medical examination to assess whether she has a disability rendering her unable to discharge her judicial duties. In re Newman. # ⚓ Dennis Crouch/Patently-O ☛ AI_and_Patent_Attorney Misconduct⠀⇛ Yesterday in my patent monopoly prosecution course, students turned to Hey Hi (AI) tools to help them draft patent monopoly claims.  None of the AI- proposed claims were ready for prime-time, but they served as a useful starting point as the students organized their thoughts.  More and more attorneys are turning to these same Hey Hi (AI) tools to help them be more productive and efficient while delivering a higher quality work product.  It is tough, for instance, to read all the prior art. Hey Hi (AI) tools can help mine the references for potential obviousness problems — and provide a pin cite to the key language in the art. # ⚓ Kluwer Patent Blog ☛ European_Parliament_supports_ban_on patenting_of_gene_edited_plants⠀⇛ The European Parliament supports the introduction of a full ban on patents for all plants produced by certain New Genomic Techniques (NGT), plant material, parts thereof, genetic information and process features they contain.

The publisher, JUVE, took bribes to promote this illegal thing, lies for this abomination. Now it tries to legitimise the illegality.]⠀⇛ Since September, NanoString has been unable to sell its products in Europe. This affects NanoString’s CosMx Spatial Molecular Imager (SMI) instruments and CosMx reagents for RNA detection. The UPC local divison in Munich prohibited this at the request of 10X Genomics. NanoString immediately appealed to the UPC Court of Appeal. # § Software Patents⠀➾ # ⚓ Unified Patents ☛ Empire_IP_entity,_Fleet_Connect Solutions,_communications_patent_monopoly_prior_art found⠀⇛ Unified is pleased to announce prior art has been found on U.S._Patent_7,260,153, owned by Fleet Connect Solutions, LLC, an NPE and entity of Empire_IP.

The '274 patent monopoly generally relates to a video compression method for improving compression efficiency in directional intra-prediction. # ⚓ The Register UK ☛ Microsoft_seeks_patent_for_tech_to put_words_into_your_mouth_•_The_Register⠀⇛ Microsoft has filed a patent application for an "automatic dubbing" system that strips speech from media and inserts new voices in its place. The patent [PDF] describes a system made up of an audio processing module, supported by visual and text code, and married with voice tracking software. The audio from a file is extracted and removed and a new voice is generated, matching the timing of the original speech, and even translating audio and text to another language if desired. o § Trademarks⠀➾ # ⚓ TTAB Blog ☛ In_a_Unanimous_Decision,_TTAB_Dismisses_SPLIT DECISION_Opposition:_Billy_Stott_Failed_to_Prove_Ownership_of the_Band_Name⠀⇛ The Board dismissed an opposition to registration of SPLIT DECISION for "Entertainment services in the nature of live visual and audio performances, namely, musical rock band," finding that Opposer Billy Stott failed to carry his burden to prove that Applicant Split Decision Music, LLC was not the owner of the mark. Stott began to "manage" the band SPLIT DECISION two years after it was formed, and claimed to be a "full, non-performing primary band member," but there was no agreement regarding ownership of the band's name. Applying the reasoning of its Wonderbread 5 decision, the Massachusetts district court's ruling in Bell v. Streetwise Records, and the CAFC's Lyons decision, the Board sided with the applicant.

Working on the other side of the law, he apprehended some 4000 criminals with a team of plainclothes agents. He founded the first criminal investigation bureau — staffed mainly with convicts — and, when he was later fired, the first private detective agency. He was one the fathers of modern criminology and had a rap sheet longer than his very tall tales. Who was Vidocq? Daisy Sainsbury investigates. # ⚓ Torrent Freak ☛ Reddit_Doesn't_Have_to_Share_IP-Addresses of_Piracy_Commenters,_Court_Rules⠀⇛ Reddit is not required to share the IP-address of six users who made piracy-related comments on the website. The company successfully protested the third attempt of a group of filmmakers, which planned to use the requested logs as evidence in their lawsuit against Internet provider Frontier. Instead of focusing on anonymous Redditors, filmmakers can go after the ISP's subscribers directly. # ⚓ Torrent Freak ☛ ISPs_Say_They'll_Happily_Cut_Pirate_IPTV Streams_as_Quickly_as_Law_Allows_It⠀⇛ Today's symbiotic relationship between content providers and ISPs, often includes the latter selling access to partners' entertainment products. That's a far cry from the situation two decades ago when very little content was made available online and ISPs' customers were viewed as the enemy. In a recent interview, an ISP that fought for seven years to prevent the imposition of piracy filtering and blocking said it's ready to cut pirate IPTV streams as quickly as the law allows. =============================================================================== * Gemini_(Primer) links can be opened using Gemini_software.

As our elected leaders continue to debate immigration reforms, they must instead advance humane and sensible solutions that help manage the border without compromising our nation’s values and the safety of people fleeing danger. Although branded as a compromise bipartisan “border security” package, this bill would have been a major rewrite of our nation’s long-standing asylum laws. To make matters worse, these changes were attached to a supplemental funding bill that also included a massive investment in failed and punitive immigration enforcement policies, such as funding to finish former President Trump’s border wall, an expansion of nationwide immigration detention, and a significant increase in surveillance targeting immigrant families. Although ostensibly dead, Senate Republicans are reportedly trying again to push for another vote on this immigration package as an amendment to foreign aid, plus additional extremist policies that would remove protections from unaccompanied children. # ⚓ The Straits Times ☛ Modi's_BJP_to_win_India's_2024_polls, seat_share_may_fall:_Survey⠀⇛ Voters continue to see Mr Modi as a popular nationalist leader, the survey found. # § Misinformation/Disinformation/Propaganda⠀➾ # ⚓ Cloudbooklet ☛ Philadelphia_Sheriff_Fake_Hey_Hi_(AI) Stories_Taken_Down⠀⇛ Discover the recent news about Philadelphia Sheriff Fake Hey Hi (AI) Stories, where Sheriff's team used Abusive Monopolist Microsoft Chaffbot to create generate fake news articles on her campaign website. # ⚓ New York Times ☛ Google_Joins_Effort_to_Help_Spot Content_Made_With_A.I.⠀⇛ The tech company’s plan is similar to one announced two days earlier by Meta, another Silicon Valley giant. o § Freedom of Information / Freedom of the Press⠀➾ # ⚓ Hong Kong Free Press ☛ Hong_Kong_Apple_Daily_founder_Jimmy Lai_asked_senior_staff_to_interview_him_on_US_lobbying_trip, court_hears⠀⇛ The founder of pro-democracy newspaper Apple Daily Jimmy Lai asked senior staff to interview him about a Washington trip he made in 2019 to lobby US politicians, a former publisher at the paper has testified against her former employer in his national security trial. # ⚓ Press Gazette ☛ Revealed:_Proposal_to_support_advertising on_Apple_devices [Ed: They are asking for new masters, more submissive a state - i.e. a mistake for reporters]⠀⇛ Private Ad Measurement is a proposal to track online ad performance on Apple devices. # ⚓ Press Gazette ☛ Life_after_Google:_Should_news_industry embrace_Amazon_and_Microsoft?

In Weber, Inc. v. Provisur Technologies, Inc., Nos. 2022-1751, 2022-1813 (Fed. Cir. Feb. 8, 2024), the PTAB sided with the patentee, but on appeal the Federal Circuit reversed — finding that Weber’s food slicer operating manuals was a printed publication.  The case shows that documents with quite limited distribution, such as operating manuals sent to ~10 customers, may still meet the public accessibility standard for prior art depending on the circumstances of disclosure and expectations around further dissemination. o § Trademarks⠀➾ # ⚓ TTAB Blog ☛ TTAB_Sustains_eBay's_Section_2(d)_Opposition_to AFREBAY_&_Design_for_Advertising_and_Payment_Processing Services⠀⇛ The Board sustained eBay's opposition to registration of the mark shown first below, for advertising and payment processing services, finding confusion likely with the registered and well-known mark EBAY in standard character form and the stylized version shown second below, for legally identical services.

Partially explainable by El Nino, but I've had some other El Nino years with weird temperatures (10 degrees at Christmas, 15 in late March) and nothing's felt quite as weird as this, even though the last week and a half has only been between maybe 0 and 5 degrees. But it's the time of year: late January, early February. This time of year the weather is always at its worst. -20 is normal.

I'm going to be voting for the first time this year in my countries General Elections (India) and I've been catching up on the politics. The more I learn the more I am disheartened. No one is ideal, I expected that much, but people somehow seem to be fine with the situation? They cling to their flawed leaders so tightly that no amount of rational criticism seems to faze them. And I'm not even talking about people I don't know, my dad - a person I consider to be very rational is like this too. # § Technology and Free Software⠀➾ # ⚓ Ideology_and_free_speech,_a_dilemma,_a_collision,_a paradox...⠀⇛ The problem i see with Ideology based hangouts is that ideologies tend to cause the very thing they tend to fight against. For instance i see places on the web where they claim to be against discrimination or racism, that in itself is all good, yet by claiming this and then set very hard boundaries to ENFORCE the ideology they happen to discriminate everyone who fails to slavishly submit to the strict rules they set out. And thereby break all the rules of freedom of speech. This then leads to all kinds of hopeless bullshit, and creates a kind of ideology based antisemetic situation that quickly goes over the edge, where the ideologist become the very discriminators they claim to fight against. # ⚓ Steam_Next_Fest_-_Halfway_Through⠀⇛ And now we're at day four of Steam Next Fest.

I like looking at apps even though they’re proprietary and tied to a proprietary platform and I’d never use them myself, just for inspiration or food for thought and discussion. Tempo was nothing new in my mind, but very new in actual practice and implementation. It was GTD principles finally applied to a mail app design. Many of design decisions that were just right; batching some senders while giving you immediate access to an allowlist, having a todo list one of the main tabs, and so on. Now here we have Gibberish, another interesting UI to study. Again, with all due respect to the implementer, it’s not a platform I’d wanna be on and, like Tempo, it costs a pretty penny, but it brings some UI innovations: it looks like a cozy chat window with the now traditional colored bubbles. # ⚓ sometimes_I_feel_like_I'm_already_failing_at_this⠀⇛ And I have to remind myself that there's no algorithm here, and there's no slavering digital sharks ready to tear the least little word apart, and -- most importantly -- that this site is for /me/, and I can post up as much or as little as I care to, at whatever speed I care to. # ⚓ non-rambling_updates_so_far⠀⇛ Well, I've got three microfictions and two microgames up on the pages off the home page, a home intro blurb for zines (but no zine page or uploads yet), some gemlog babbling and rss feed links + my fedi account. =============================================================================== * Gemini_(Primer) links can be opened using Gemini_software.

Yet rather than vanish into nothing, the debris of this destruction remains partially in the atmosphere, where it forms pockets of material. As this material is often conductive, it will likely affect the Earth’s magnetic field, as argued by [Sierra Solter-Hunt] in a pre- publication article. o § Science⠀➾ # ⚓ Science Alert ☛ Humanity's_Impact:_'Lunar_Anthropocene' Spurred_by_500,000_Pounds_of_Trash_on_The_Moon⠀⇛ Have we not learnt from our mistakes on Earth? # ⚓ Science Alert ☛ Earthquake_or_Secret_Nuclear_Blast?_A_New Tool_Exposes_The_Truth_With_99%_Accuracy⠀⇛ Ensuring governments are held accountable. o § Hardware⠀➾ # ⚓ Hackaday ☛ Vesuvius_Challenge_2023_Grand_Prize_Awarded_And 2024’s_New_Challenge⠀⇛ In the year 79 CE, a massive cloud of volcanic ash rained down on the Roman city of Herculaneum after an eruption of Mount Vesuvius.

After the charred but still recognizable scrolls were found in the 18th century, many fruitless attempts were made to recover the text hidden within these charred ruins, but not until 2023 did we get our first full glimpse at their contents, along with the awarding of the Vesuvius Challenge 2023. # ⚓ Jonathan Dowland ☛ Jonathan_Dowland:_carbon⠀⇛ I got a new work laptop this year: A Thinkpad X1 Carbon (Gen 11).

Now we know more about which subsidiary studios will take the hit. First reported by the San Francisco Chronicle (via Eurogamer), California WARN notices list 86 upcoming scheduled layoffs at Skylanders maker Toys for Bob and 76 cuts at Call of Duty: Vanguard developer Sledgehammer Games. California requires companies to notify the state of upcoming layoffs, thanks to a 1988 law mandating 60 days’ notice about staffing cuts (if they reach specific thresholds). The latest WARN alerts for Activision Blizzard report 86 upcoming cuts at an address in Novato, CA — matching Toys for Bob’s offices — effective March 30. In addition, the San Francisco Chronicle reports on a California state filing indicating Toys for Bob’s offices will close. # ⚓ EuroGamer ☛ Microsoft_layoffs_affect_86_staff_at_Spyro, Crash_Bandicoot_studio⠀⇛ Activision Blizzard's Crash Bandicoot and Spyro studio Toys for Bob lose 86 employees as a result of layoffs. These people are part of the wider round of layoffs Microsoft is undertaking, which will see 1900 employees across Xbox and Activision Blizzard lose their jobs. The layoffs at Toys for Bob are much higher than previously estimated - a report from two weeks ago claimed between 30 to 40 percent of jobs would be affected, which was estimated to be around 35 people. # ⚓ Gizmodo ☛ Feds_Say_Activision_Layoffs_Violate_Promises Microsoft_Made_in_Merger_Deal⠀⇛ The Federal Trade Commission isn’t happy with the outcome of Microsoft’s $68.7 billion acquisition of Activision Blizzard, telling a court on Wednesday that Microsoft’s recent layoffs contradict promises it made to get the merger approved. # ⚓ FTC_seeks_pause_on_Microsoft-Activision_deal_amid_layoff controversy⠀⇛ Just a week following Microsoft’s announcement of nearly 2,000 layoffs within its gaming division, the Federal Trade Commission has raised concerns over Microsoft’s adherence to its initial promises regarding the operation of Activision Blizzard post-acquisition, according to a recent report by Engadget. The FTC’s apprehensions were formalized in a complaint submitted to a federal appeals court on Wednesday, calling for a temporary halt on Microsoft’s acquisition of Activision Blizzard amid ongoing investigations into potential antitrust violations. Microsoft had previously assured the FTC that the acquisition of Activision Blizzard would be managed as a vertical integration, implying that layoffs would be unnecessary due to the absence of overlapping roles. However, the recent job cuts announced on Jan. 30, which impacted employees across Activision Blizzard, ZeniMax, and Xbox, have sparked controversy. Microsoft cited “areas of overlap” between itself and Activision Blizzard as the reason for the layoffs, a statement that the FTC claims contradicts Microsoft’s earlier representations to the court. # ⚓ Neowin ☛ Microsoft's_gaming_layoffs_will_cause_Activision's Toys_for_Bob_physical_office_to_close⠀⇛ The San Francisco Chronicle reported that the physical offices of Activision's Toys for Bob development studio will close in Novato, California. The studio was first formed in 1989 and became well known for creating the Star Control series of space strategy titles. Activision acquired Toys for Bob in 2005. The studio then created the popular Skylanders series of games. Still, after the studio's founders departed in 2020, Toys for Bob became a support studio for the Call of Duty game series. # ⚓ Activision_closes_Toys_for_Bob_and_Crash_Bandicoot_studio offices;_layoffs_reported⠀⇛ Activision Blizzard, now owned by Microsoft, just went through a round of layoffs that also included Toys For Bob, the studio best known for being responsible for recent installments of Toys For Bob.

As the trial began entering its final stages last week, attorneys for Michael E.

Parked tractors brought traffic to a standstill in Paris, and on Thursday burning piles of hay and debris sent up huge, dark plumes of smoke in Brussels. The protests show no sign of slowing down and are expected this week across Italy, Slovenia and Spain. Farmers’ demonstrations have been portrayed as a revolt against net zero, by the media and far-right groups.This is the message received by governments – and they are acting on it. So far, the farmers have won key concessions, with the EU decision on Tuesday to drop its plans to cut pesticide use, hot on the heels of the same move by France on Friday, despite numbers of birds and pollinators plummeting in Europe.Yet the reality on the ground in Brussels last week was more mixed. While Europe’s largest farming union, Copa-Cogeca, paints environmental measures as an enemy to farmers’ prosperity, an analysis by Carbon Brief has found that a fifth of farmer concerns were not on green issues, relating instead to high production costs, food pricing and trade-related concerns.Other  groups of farmers came out onto the streets of Brussels with a different message. They say the EU should see the protests as a sign to do more, not less, to protect the environment. # § Wildlife/Nature⠀➾ # ⚓ The Revelator ☛ Is_Our_Food_Waste_Creating_a_Murder of_Crows?⠀⇛ # ⚓ Science Alert ☛ Bizarre_Prehistoric_Predator_Fish Breathed_Air,_Had_Fangs_And_Four_'Limbs'⠀⇛ A 380-million-year-old identity crisis. # ⚓ Science Alert ☛ Rare_3D_Fossil_of_Trees_Older_Than Dinosaurs_Reveals_Bizarre_Alien-Like_Ancient_Forests⠀⇛ "A strange growth form in the history of life." o § Finance⠀➾ # ⚓ The Straits Times ☛ South_Korea’s_foreign_worker_plan_put on_hold_as_Philippines_suspends_labour_deployment⠀⇛ The deployment of Filipino farm workers was also suspended due to human rights violation complaints. # ⚓ The Straits Times ☛ Prosecutors_to_appeal_after_Samsung chief_Lee_cleared_over_2015_merger_case⠀⇛ South Korean prosecutors have decided to appeal a court decision to clear Samsung Electronics Chairman Jay Y.

Across from him in the crowded sanctuary, a half-dozen West African men recited the Quran on the chancel and a man from China talked with a woman on WhatsApp. Ramon, who is from Venezuela, put on the snug-fitting winter parka he’d found in a donation bin and walked out into the biting cold to figure out where to pass the day. It would be nearly 14 hours until another church, an hour and a half away by subway in Harlem, would take him in. Ramon had already spent a week crisscrossing the city in search of a safe place to lay his head. During his first month in New York he lived in a shelter, but he couldn’t stay. The city recently began limiting single adult migrants to a 30-day stay with an option to reapply for another 30 days, though the wait to get back in can be lengthy. New York hastily launched its new migrant reception system in the spring of 2022, and since then more than 170,000 people have passed through it. As with Ramon, some of them came on free buses from Texas, ending up in New York not because it was their chosen destination but because they had no other option. Many were part of Texas Gov. Greg Abbott’s initiative to funnel people entering the country into liberal cities and to export the stresses and tensions of the southern border into farflung parts of the country. New York is an attractive landing place because it is the only major U.S. city that’s required, pursuant to a four-decade-old consent decree, to provide a shelter to anyone in need. # ⚓ EDRI ☛ EDRi-gram,_7_february_2024⠀⇛ In this edition of the EDRi-gram, we'll be discussing the Irish Media Regulator's proposal to implement mandatory age verification that could impact all EU Member States.
