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

Flow is the manifestation of Blender’s mission, where a small independent team is able to create a story that moves audiences worldwide.

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.

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...

There are slides about the PREEMP_RT evolution based on my followup, use and experiments with GNU/Linux in #realtime projects from time about 2.6.18 kernel version - Linux RT Patches Mainlining – Submission Wrapped in the Gold. The talk has been presented on OpenAlt 2024 conference. There is recording in Czech language. If there is interest, I can prepare presentation in English or I am open to provide my photos and materials from 20 years history if somebody wants to prepare better presentation. I have prepared more RT and #osadl RT testing related articles usually with English text but often witch Czech language recording for local community. The list is there https://gitlab.fel.cvut.cz/otrees/org/-/wikis/knowbase.

DevConf 2023 CAN Bus in Control, Automotive and Satellitelites direct recording https://youtu.be/RwmQYjfzQAg and slides https://static.sched.com/hosted_files/devconfcz2023/f2/devcon23_linux_can_latency.pdf links added for archival purposes. The projects are active and we monitor current mainline and RT kernels daily for more than year https://canbus.pages.fel.cvut.cz/#can-bus-channels-mutual-latency-testing as well as support CTU CAN FD IP core integration to chips and its and other #CANbus drivers for more OSes and QEMU simulations.

Thanks for the TDE maintenance. I use it on my laptop and like that I can use same home, address book and e-mail setup for decades.

It is in line with David Patterson's today retrospective presentation about his and Krste Asanovic 2014 article which started #RISCV movement - Instruction Sets Should Be Free: The Case For RISC-V https://people.eecs.berkeley.edu/~krste/papers/EECS-2014-146.pdf . It is the same as for the operating systems, compilers, development tools, etc.

Our site with the on-line simulator and pointers to the courses and related materials https://comparch.edu.cvut.cz/ . CTU FEE ones are completely free as the public university materials should be free for profit of whole society the same as the ISA and other technology standards.

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.

PMSM motor control on ICE-V Wireless (#Espressif #RiscV ESP32-C6 + iCE-40 #FPGA) project has been presented at #LinuxDays https://pretalx.linuxdays.cz/linuxdays-2024/talk/QGST3J/ (Video in Czech ), (Presentation PDF - English), Jakub Janousek’s related thesis (PDF - Engish) and project site https://gitlab.fel.cvut.cz/otrees/risc-v-esp32/ice-v-pmsm . Presentation starts with robotic platform based on ESP32-C6 chosen as cheap option for teaching Microcomputer Engineering with Space Applications course @LTUniv in #Kiruna in #SpaceMaster https://spacemaster.eu/ on M-Bot like platform. The related QENC driver by Martin Vajnar for ESP32-C6 is in mainline #NuttX now.
