@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.

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?

@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.

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.

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.
