@pavel @pabloyoyoista My personal feeling is that people are getting too much sensitive (including myself sometimes) and that they should be taught that technical opinion and fact should be expressed without hiding even hurting facts. But on the other hand it should be expressed and made clean that it is not personal attack etc. On the other hand I agree that programming and even all complex technical decisions are about feeling and taste because no human or even ML system has enough memory and computational power to do real deep search in all alternatives. The state space of possible solutions is to large. But I have my personal feeling (yes again that wold), than it is much worse to attempt to hide facts or be afraid to pass forward what you believe are facts. Then everybody needs to analyze if that what you say is what you mean or if you say it that way that you afraid etc… So nobody can build idea about different persons thoughts about his, her code etc… So I consider that it is right when I sometimes feel injustice caused to me or I cannot find same point of view as others. But it should not lead to lies, defamation etc. In the worst case, the result should be agree to disagree which can lead even to project fork or move to another project. May it be, the opinions can be communicated later and advantage of joining the forces prevails losts required by compromises. (Excuse my English, may it be it can shift my idea a little from what I mean and “feel”).

Open-Source Chips for Europe
https://open-source-chips.eu/

"We already see rising interest from many EU stakeholders, with increasing investments into open-source chip design, especially in open source IP development (e.g. RISC-V cores), and open source EDA tools.

One additional critical barrier remains toward the end-goal of building real open-source chips, especially for prototyping and education: namely, streamlining the access to open source chip production facilities (foundries) is essential."

@eunews Anyway, Patriot Act and other directives mentioned in the Register article by Frank Karlitschek, CEO of Nextcloud "The Cloud Act grants US authorities access to cloud data hosted by US companies. It does not matter if that data is located in the US, Europe, or anywhere else." do not make me feel good about actual #cvut move to full dependance into Azure/Entra ID entity management dependance and gaining our personal and servers data.

I am looking for an alternative without disruptive and distracting advertising that our students could use for a long time, and I am happy that we can test the alternative you provide. I had become angry many times when I needed to check/scan my or my colleague's previous lecture recording to follow with the next one fluently and have been forced to wait for three or five seconds after three seekings from the four. Thanks for your PeerTube setup. We will see if it will be appreciated by our students and the worldwide community, which uses #riscv for teaching. But in the long term, solutions backed by some stronger provider as is #cesnet are necessary for some wider use. I have seen that foreign universities use https://en.wikipedia.org/wiki/Kaltura, but may it be PeerTube can prove to be better choice.

For Czech language understanding visitors, I have uploaded even the recording of the Advanced Computer Architectures/Pokročilé architektury počítačů [ZS 2021/22] lectures onto advertisement free VHSky.cz site https://vhsky.cz/my-library/video-playlists/6akpEt7UVq3k6NzXdsY5Hd . Original recordings on YouTube . There exists even much lower quality English language recordings from #BigBlueButton sessions during COVID lockdown which can be found on the subject pages https://cw.fel.cvut.cz/wiki/courses/b4m35pap/start

The VHSky.cz server playlist https://vhsky.cz/w/p/8Ejstt3Tfh8mWGcjQcEL2S
Thanks to @archos and @sesivany for providing advertising free storage on the server which they have setup. My VHSky.cz local account is @ppisa and I am learning how the content can be federated. The channel is @ctucomparch

The B35APO Computer Architectures course based on #riscv and our #qtrvsim simulator reached new (re)usability level, updated slides in the LaTeX Beamer format for lecture 1 to 10 are translated to English, PDF, CC-BY-SA Slide Sources at #cvut FEE GitLab and on GitHub. The feedback, corrections, suggestion, reuse and cooperation are welcomed. The lectures recording are available on community driven PeerTube server https://vhsky.cz/w/p/8Ejstt3Tfh8mWGcjQcEL2S and CTU FEE B35APO YouTube List. The online site with links to more related courses and on-line QtRvSim WASM application https://comparch.edu.cvut.cz/ allows even online evaluation of simple #riscv assembly and C exercises.

If Europe is going to break from US-based tech will it embrace FOSS or just duplicate the US for-profit, capitalism-based model of computing?

@M4RSarK Have CTU #cvut IT experts considered alternatives to moving to Microsoft Entra ID next week? As I understand, MS Azure would be the authoritative source of all our university identities, and there (hopefully) will be some slave copy of Active Directory on our university servers. Unfortunately, my official ticket has been closed with the statement that information about the security system solution and contracts with Microsoft are confidential. Experts have taught me in the past that each system based on security through obscurity is only a temporal solution and usually indicates a bad design. Have you consulted #cesnet, RedHat, SUSE, CZ.nic? It seems, according to #lwn article Lessons from open source in the Mexican government, that Mexico is more aware of the potential risk to depend on the systems controlled by other country (one not-so-old example). I am not expert for security and it is not interesting area for me, I have already quite large portfolio, but I am so frightened that I would ask people form RedHat, SUSE, CZ.nic to start to gain some basic knowledge in the field to know what are the alternatives. If somebody reads this and have experience with alternatives for authentication system for organization with 20k+ personal accounts and lot of roles (I do not know the number, again classified as confidential, even that do not know any reason), then I would be happy for reply.

@sesivany @systemz @organicmaps My sympathy and hopes for friendliness to the community of Seznam.cz and their map team lowered a lot a few months ago. But on the other hand, I have heard from some source, I think internal, that they have switched to OpenSTreetMap layers for some objects even in Czech republic, I think that park benches has been mentioned. Interesting that yours have not propagated to their maps yet, but they do considerable data processing and cleanups/unification during planet import into their maps formats. So it can take some time. But anyway, it would worth to ask them if the given layer of the paths is from OSM for whole Czech republic and if they have committed back or provided by other means all their corrections and data from their proceeding sources.

#Mapycz (now #Mapycom) from #Seznam use #OpenStreetMap everywhere except their home country - Czech Republic, where they have their own proprietary maps.
There have been rumours in the #OSM community that they actually copy from OSM. Today I found proof that they really do.
I mapped a new park in #Brno just by surveying and taking notes last year. Later the park showed up on Mapy.com with exactly the same path layout. The new orthophoto is out and it revealed that I didn't get everything right and Seznam got it wrong too. Exactly the same mistakes.

Not cool, Seznam.

@M4RSarK Excuse me, but you are at charge at FEE CTU IT ( #cvut ), so why is the only public way (with tracked history) to communicate with our faculty senate over Discord and it is advertised at senate candidates debates, why we will be most likely forced to switch to Microsoft two-factor authentication, e-mail etc. I know that these things are not so simple, but at COVID outbreak, one our admins (Daniel Vecerka) set up BigBlueButton instance on our servers in less that two weeks and final integration with courses schedules from study system database, recording, recording processing etc. is far more advanced then what I have seen in Teams which are pushed to us for communication by top management. Same for the PR department which feeds Twitter/X, YouTube etc. I know that it is hard, but we should have FEDIVERSE at social.cvut.cz, we should have Discourse etc… I use for my projects and subjects Debian/GNU/Linux for decades for decades and no closed tool at all. I contribute to whole world to have alternative for computer architectures teaching on open architecture (RISC-V) with open tools https://comparch.edu.cvut.cz/ and with open lectures sources. My groups of students contributes to open system for control systems and theory education and may be even devices design (pysimCoder), yes it is toy still, but used worldwide and gaining momentum. But at our department it is downplayed and I can expect that in some time there would be no lab with computers and enough Ethernet connections for embedded targets to run the environment directly. I have been forbidden to participate in the discussion about the future of K2, other labs, rooms where I work with my students. So I suggest even to you to approach downstairs from the clouds and global world dreams and solutions and solve manageable problems at reachable level. Discuss with CTU FEE PR, that we should start to have alternative to AI and mighty controlled channels, we should teach students basis which allows them to setup own systems, build own space grade controller (our RTEMS BSP is used by Airbus Defense and Space USA, my former diploma students contributes to ESA CPU desig, so the claim is exaggerated only a little) etc. OpenAlt has moved to local PeerTube instance vhsky.cz. Why am I forced to register and even pay to can check my own lectures on YouTube without advertisements when there is #cesnet which is paid from public money to provide support to Czech universities… and I can continue.

Congratulations to Gints Zilbalodis and the entire Flow film crew for the Academy Award win!

Thank you for the shout out! 🧡 #b3d

The project reuses our GNU/Linux CAN activities started in nineties and related CAN and CANopen OrtCAN libraries (https://ortcan.sourceforge.net/) support SoketCAN, original Linux LinCAN, NuttX and now even new RTEMS CAN API. Extension of pysimCoder to support RTEMS in addition to GNU/Linux and NuttX is planned and some initial experiments has been already built. It can be alternative to its use with NuttX described in the article An Open-Source Python-Based Framework of Real-Time Controls as Flight Software of CubeSats. The all these project are in beginning but it is nice adventure and space for joining people and companies ahead.

Our RTEMS CAN API with CAN FD and priority class queues (result of Michal Lenc’s thesis) has been accepted into RTEMS.org mainline. The related article Scheduling of CAN Frame Transmission when Multiple FIFOs with Assigned Priorities Are Used in RTOS Drivers was presented at International CAN Conference 2024. The maximal gateway latency under load with CTU CAN FD IP core on Zynq (MZ_APO) is under 65 µsec. Development of two more controller drivers is under development and we hope to find some GSoC participants to support even more hardware as well. #canbus #realtime

Wikipedia is rolling out anonymity features piloted in countries with authoritarian governments in the US & is making a change to not show editor IP addresses in response to a global "increase in threats" from Elon Musk, Heritage Foundation, and governments

The recording of my talk about RT_PREEMPT history and its use in our projects is available on the talk page. I have tried to put a complete view and information into the talk, and due to speed and my English, the presentation is far from ideal. I have probably thought about our initial 2.6.x kernel-based RT_PREEMPT projects when I said version 2.12 and 2.13 instead of 6.12 and 6.13. But I think that slides are valuable at least. More talks and slides mainly about the use of GNU/Linux and other RTOSes for the control intended for enthusiasts, students and even experts are available at https://gitlab.fel.cvut.cz/otrees/org/-/wikis/knowbase

I will talk about #realtime Linux kernel support, applications and history at #FOSDEM 2025 based on our experience at #CVUTFEL and my company for robotics, automotive communication ( #CANbus ), etc. The talk is based on my last year Czech language talk for the local community (Slides in English) reporting about PREEMPT_RT mainlining. Discussion and suggestions for slide fixes/extensions are welcomed as my talk has been accepted as no other better has been offered by more knowledgeable developers.
