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?

#Linux #FOSS

#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.

Not reported much in US media, but mentioned in this Forbes article and big news in Europe...

"...the administration of U.S. President Donald Trump has halted U.S. aid to Ukraine, including vital support for the F-16s’ radar jammers."

So get this straight, the US is disabling vital capabilities of a weapons system a US company sold to an ally.

Putting aside the horrendous ethical and political implications, what allies are now going to buy these vulnerable US weapons?

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

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.

As it turns out, Volkswagen has been collecting extensive geo data from all their electric cars and made them available online in an AWS bucket. Almost 10TB of geo traces from 15 MiO cars. Amazing detail and patterns. This is why I don't want a smart car 🤯 https://events.ccc.de/congress/2024/hub/en/event/wir-wissen-wo-dein-auto-steht-volksdaten-von-volkswagen/ #Volksdaten

Hi #Fediverse, let's start our journey here with our #introduction. We are #Turris project by #CZNIC. We develop and produce #opensource #wifi #router with focus on #security running #Linux distribution based on #OpenWrt. Of course, we provide automatic #updates and #root accounts. We have a #network of #honeypots running on our devices and create a dynamic #firewall based on the data.

Linux 6.12 Released With Real-Time Capabilities, Sched_Ext, More AMD RDNA4 & More

As expected, minutes ago Linus Torvalds just released the Linux 6.12 kernel as stable. Linux 6.12 brings many new features, new hardware support, and is rounded out by the fact of expected to become this year's Long Term Support (LTS) kernel version...

Greetings from the RISC-V Summit North America 2024 https://riscv.org/event/risc-v-summit-north-america-2024/ . Many interesting topics have been presented there. My main interest is to connect with other computer architecture teachers to discuss materials and experience sharing in the frame of #RISCV SIG Academia and Training. In the picture is David Patterson after my introduction of #QtRvSim to him.

Part of CTU FEE OTREES HW ZOO at #LinuxDays booth. On the left , #RiscV #milkvpioneer with #fedora desktop running #CHROMuLAN, #qtrvsim with new branch predictors visualization and Elektroline.cz Silicon-Heaven SHVspy https://github.com/silicon-heaven/libshv. On the right, x86 Debian running Silicon-Heaven broker and #pysimCoder https://github.com/robertobucher/pysimCoder to generate and runtime tune PMSM control application running on #NuttX on open-source motion control platform SaMoCon https://gitlab.fel.cvut.cz/otrees/motion/samocon which is a result of Stepan Pressl's thesis https://wiki.control.fel.cvut.cz/mediawiki/images/4/44/Bp_2024_pressl_stepan.pdf . On the left in front, MZ_APO Xilinx Zynq based educational kit running Debian from NFS RO root. Its FPGA is configured by 2x CTU CAN FD, PMSM motor control peripherals and RVapo #riscv soft core co-processor used for inverse and forward Park and Clarke transformations for PWM, current sensing and calibration all running at 20 kHz in sync with PWM cycles. The soft core was started by Eduard Lavus as PAP course project and has been extended and integrated with PMSM by Damir Gruncl - see more about these projects in the OTREES theses list https://gitlab.fel.cvut.cz/otrees/org/-/wikis/theses-defend

New release of #qtrvsim #riscv simulator for education. QtRvSim v0.9.8 adds Jiri Stefan's work on branch predictor. Its visualization extends cache, pipeline, memory and other visualization capabilities (https://github.com/cvut/qtrvsim/releases). Online version available at https://comparch.edu.cvut.cz/ . There is new WebEvaluator site link and description available (work of Jakub Pelc) for training on simple assembly and C tasks. The project will be discussed at RISC-V International Special Interest Group: Academia and Training meeting at October 10 2024 at 8 AM Pacific Time (5 PM CEST). The feedback is welcomed. I will be present on 2024 RISC-V Summit North America too.

Last night at the real-time celebration, Thomas Gleixner handed Linus Torvalds his official pull request of the real-time patch on paper "wrapped in gold with a ribbon around it''

#CHROMuLAN running chromatography data acquisition from ULAD32 on Milk-V Pioneer box #milkvpioneer 64-core RISC-V system. Application has been built on that system as well as #freepascal and #Lazarus LCL actual mainline GIT versions. uLAN kernel driver for instruments connection and control has been build directly on the system as well. Our #QtRvSim #Qt based simulator builds and on this #riscv system as well. More about our open-source chromatography system serving users more than 20 years there https://sourceforge.net/projects/chromulan/

It seems to have happened without much fanfare, but about a month ago @purism has released the Librem 5 hardware layouts under GPLv3 (as original PADS and converted KiCad projects), joining the schematics that were already available from the start.

We will present our new #canbus (CAN/CAN FD) stack for #RTEMS (https://www.rtems.org/) on #CiA_iCC https://old.can-cia.org/icc in Baden-Baden on Wednesday 15. The stack is based on our LinCAN Linux driver (initiated in 2003 as part of https://ortcan.sourceforge.net/ ). The new code source and documentation is available at https://gitlab.fel.cvut.cz/otrees/rtems/rtems-canfd . Our presentation "Scheduling of CAN frame transmission when multiple FIFOs with assigned priorities are used in RTOS drivers" is relevant even for future Linux #SocketCAN stack to solve its long standing link level priority inversion problem at least for some controllers when multi-queue support is implemented and our previous QoS work is updated. The measured latency results on #zynq on #RTEMS are great and in order better than maximal ones on PREEMP_RT Linux https://canbus.pages.fel.cvut.cz/#can-bus-channels-mutual-latency-testing . So there is lot to do on Linux side as well.
