It looks like my #aiagents file finally got into #qemu. Hopefully it will have some effect: https://gitlab.com/qemu-project/qemu/-/commit/3ab8a15569afa9ffd89971dff34d0636d48cae3c

I will attend the ESA Industry Space Days next week. I would be happy to meet and discuss our #RTEMS, #Linux, #NuttX, communication, #canbus, #SpaceWire, IP cores related work. Some examples

• for RTEMS CAN/CAN FD, there is near to merge Ti AM335x suport, result of this year Ning Zhang #GSoC
• motion control at #PiKRON (used by ESA for #satellite tracking and for LISA ground experiment), and at #CVUT (SaMoCon)
• for rapid prototyping CTU Simulink™ support for Linux and NuttX which can be easily extended for RTEMS and open-source pysimCoder which already target Linux, NuttX and RTEMS (ongoing preparation for Ahmad Hisham’ s thesis)
• the CTU CAN FD IP core is already available on mass produced MCU COTS silicon in addition to multiple FPGA applications including space ones
• RTEMS LwIP port started as our experiment during Premysl Houdek’s thesis and #GSoC is getting traction and was used at docking computer during Artems II mission (by the way, there will be presentation about the mission at #cvutfel by Milan Halousek at Sptember 24) and is used on TMS570 and ESP32C3 RTEMS ports
• our SumInt ADC conversion principle used in our HPLC instruments and tested at #nanoXplore for ESA which can have interesting potential for space silicon
• our NuttX support for IEEE 802.3cg 10BASE−T1S Open Alliance SPI MACPHY can be ported to RTEMS etc.
• I offer support for CAN/CAN FD emulation on #QEMU, #FlexCAN added this year
• lot of our other real-time work for Linux, NuttX and RTEMS, se my university Open Technologies Research Education and Exchange Services topics and theses lists
• we invest lot into #RISCV education at CTU, see our https://comparch.edu.cvut.cz/ pages with #QtRvSim emulator and our HDL education and sometimes even practically used cores and experiments

I arrive to Noordwijk around the lunch time on Tuesday September 15 and stay there to about 2 PM on Friday so there is lot of options to meet.

Here is another in a series of attempts to divine information from #qemu's issue tracker. I think this is showing that #AI #bugpocolypse reports tend to be verbose, a lot of sanitizer reports are probably mislabelled (quite often the agent will show the failure in a sanitized build) and having a decent test case correlates well with undeclared agent use. The "normal" size of reports for each class of device in (Untagged) for any tooling or TestCase.

Как QEMU исполняет чужой код: изучаем Tiny Code Compilator изнутри

QEMU — это не просто виртуализация с KVM. Его главная cуперсила — способность запускать программы, скомпилированные для одной архитектуры, на совершенно другом процессоре. Безо всякой поддержки со стороны хоста. Например, запустить прошивку для ARM-микроконтроллера на x86-ноутбуке. Как это работает? Под капотом QEMU скрывается JIT-компилятор под названием TCG (Tiny Code Generator). В этой статье мы разберем его устройство на практических примерах для RISC-V и посмотрим, как инструкции превращаются из одного машинного кода в другой, как формируются блоки трансляции, и зачем там нужны longjmp и цепочки блоков.

#weeklyreview 24/2026

This was a busy week. Two social events and long work days. Of course also more fiddling with tech. But it all started with the 4th

Digital Independence Day Templin/Uckermark

For the fourth time we met in Templin to show and tell people about alternative to big commercial technology. This time a bunch of new faces showed up and we were a total of 8 people. Its getting traction despite our lousy advertisement efforts.

One quote from my partner in crime resonated with me especially:

You don’t need to switch directly from Windows to Linux. Rather start replacing application by application with their open source alternative. Once you’ve replace InternetExplorer or Chrome with Firefox, MS Office with LibreOffice and Outlook with Thunderbird, you’ve likely already covered the majority of your computer use. When you then switch from Windows to Linux you’ll be met with familiar applications already.

The 5th event will take place on July 5th in Templin again.

Movies & Paintings

Back on Sunday evening Berlin K2 started to watch a movie it seem to like. The story is about a woman at the end of the 18th century. She’s supposed to get a portrait of her painted by a another woman.

The scenery looked more and more familiar the longer I watched. Eventually it struck me. One scene of that movie we’ve got as an painting from my dear friend Cristina Carrillo.

The movie is the french “Portrait of a lady on fire” by director Céline Sciamma and it’s really good.

Greybeard gathering

As it was the 2nd Tuesday of the month our group of old hackers gathered again at the Pratergarten. This time it was warm enough to start sitting outside in the beer garden and in the sun. One guy joked that direct sunlight is not the right environment for hackers.

Why greybeards you ask? Because a lot of the original male software developers of Unix (think Kernighan & Ritchie ) were sporting full beards and eventually those became grey. Funny enough in our group I’m the only one with a beard … and I’m not a hacker.

Always quite an interesting meeting as those guys know a lot beside mere programming and computers. Learned quite some things about Taurus weapon systems this time.

Linux to the rescue

A friend of mine water damaged their HP Laptop. Wouldn’t boot up anymore despite the fans turning when powered on. I took out the harddrive to see if that’s still working. And it is. Got Windows 11 on it. Now while we have access to the mere files, some valuable data is still hidden inside programs and their proprietary formats.

Unfortunately the Disk didn’t fit in own HP laptop as it’s got a different SSD connector. What I had though is a SSD-to-USB adapter. I thought it should be possible to create a virtual machine though that simulates the original Laptop to some extend and use the USB-device as it’s hard drive. The normal VM wizard didn’t lead to success so I asked Perplexity to help me create the correct QEMU/KVM call.

And it delivered. I needed to create a software TPM device first as the original Laptop uses UEFI. After some fiddling I actually got the original OS booting up on my trusty Linux Laptop despite some 10 years hardware difference. The Documentation and explanation of the steps can be found here.

My friend but has now bought a similar laptop as replacement. We’ll put the disc into the new Laptop and will hope that the system will just come up. Let’s see. But good to know that my approach would have worked using virtualization.

Beer & Burgers

On Thursday it was time for our beer & burger gathering again. This time in West Berlin … Upper Burger Grill in Charlottenburg.

The Burger was quite OK. Not the best I ever had … but also not the worst 😉

After the burgers we felt fancy and decided to pay the Monkey Bar a visit. That’s a quite popular bar at the moment at the end of the Bikini House Berlin. It oversees the “Zoologischer Garten” and I guess you could see the monkeys during the day.

The view is indeed stunning. You can see over to the Gedaechtniskirche, the Bikini House and of course the Zoo. What I found most interesting was the audience. Every age group from Teenagers (I hope 16+) to people probably approaching their 80s were there. So they’re doing something right attracting such a diverse age group. Then again the Ku’damm area feels a little weird to me. Everyone seems to be pretending their rich and famous. Some surely are. Most just pretend and want to part of the hype. Also… it seems to be mostly russian speaking people nowadays in that Area.

Elk

This week the Version 1.0 of the alternative web client for Fediverse services named “Elk” was release. I’m hosting my own instance and are using it currently as my main Mastodon Client on the web.

One nice notable feature (among many others) is it’s ability to compose longer threads. The compose window let’s you split your longer writings into multiple properly linked posts. I know that some people struggle with this. Many Fediverse instances have a character limit for their posts – usually 500. I’ve patched my Mastodon instance to allow 5000 characters in a single post. So if your instance has a short limit and you want to post longer texts then consider using Elk for this purpose.

Local LLM stuff

I’ve continued playing with my LiteLLM setup. Also finally got OpenCode configured and used Qwen3.6 with Ollama on my laptop to write me some Ansible playbooks for installing and configuring OpenCode. That worked quite well.

I’ve also tried to calculate the cost of my Ollama setup on my Laptop at the energy price of 30ct/kWh. The M2 Max CPU/GPU seem to be able to churn out ~ 50 Tokens/s while consuming 65W. For 1M tokens it would roughly need 5.5 hours at 65W. That’s about 0,3575 kWh and thus ~ 10,7ct/1M tokens.

Of course I build myself a benchmark tool that produces the numbers for all available models on my machine and spits out a respective config file for LiteLLM

[Перевод] Как я убедил виртуальную машину, что у неё есть кулер

Зачем вообще этим заморачиваться? Некоторые образцы malware выполняют различные проверки, чтобы определить, запущены ли они в виртуальной машине. Один из самых частых способов — проверка наличия определённых аппаратных компонентов, обычно не эмулируемых в виртуальных средах. Один из таких компонентов — кулер процессора . Например, malware может проверять наличие кулера процессора, поискав в WMI класс Win32_Fan : wmic path Win32_Fan get * Они делают это, чтобы не запускаться в виртуальных машинах, усложнив таким образом процесс анализа для исследователей безопасности. Зловредное ПО может определять, запущено ли оно в виртуальной машине, множеством разных способов. Есть различные классы WMI, позволяющие обнаружит присутствие виртуальной машины, например, Win32_CacheMemory , Win32_VoltageProbe и множество других . В этом посте я расскажу о кулере процессора. Мне просто понравилась идея убедить виртуальную машину, что он у неё есть. Однако такой же подход можно применить к другим аппаратным компонентам и классам WMI.
