So, today I was informed that my current employment is terminated. This implies that I will be looking for a new job. I know it might be a stretch, but I thought why not give a try. Due to many circumstances, it has to be a full-time position in . 🇩🇰

I can bring my senior expertise in IT security and vulnerability research. We can, of course, discuss related roles as well. You can find my profile at: https://www.linkedin.com/in/infosecdj/

I can also market my decapping and deprocessing skills, but I fear the market depth for that is in single digits. :-) But if someone has interest, please feel free to have a look at http://infosecdj.net/ for what I was able to do in my home lab!

Of course, any and all boosts will be greatly appreciated. Thank you!

Vibe coded software is the digital equivalent of forever chemicals. Hard to get rid of and its long term effects are still unknown. But they look like a miraculously simple and fast solution to a multitude of problems.

You need to reevaluate your priors. The fridges are so powerful now, and what was true of refrigeration a month ago simply isn’t now. If your fridge isn’t connected to the internet with a known admin password, and can’t heat up to 50°C you’re going to be left behind.

Meet 🌟 Stonking Stingray 🌟.
Created with Krita, Blender and 1% GNU Image Manipulation Program. It took a month to paint it. Inspired by the Ubuntu release name 26.10 scheduled for release on October 15!

Sexism aside, I think prizes like this do a lot of damage to the image of science as a whole. In Newton’s day, you could lock yourself in a lab and discover or invent something novel alone. But even Newton admitted he was standing on the shoulders of giants.

For at least the last hundred years, science has been a team sport. Focusing on the success rather than the process is a celebration of luck more than anything else. A hundred teams explore quite plausible hypotheses. One team hits something that isn’t falsified. You give a prize to the person who was first author on the paper. That reinforces the idea of a hero scientist and detracts from all of the work necessary to get to that point.

It means that people who care about the collaboration are discouraged from entering the field (which is one of the many causes of the continued gender imbalance).

It means that funding agencies don’t internalise the idea that you need to fund a lot of work that will fail and keep trying to pick the one savant who will always succeed.

It means that the work of most people in the field is undervalued.

It promotes toxic politics in labs with clout harvesting an obsessive behaviour for the people aiming at these things.

It promotes secrecy in research so you don’t get ‘scooped’, rather than sharing early data so other people can rapidly build on it.

So the Czech train has a WiFi connection which at least works, but:
- It shows a 30(!) second ad on login with no option to skip it.
- It uses an effective MTU of 1200 bytes, which is less than the minimum 1280 required by IPv6, so it breaks v6 connectivity completely.

So yeah, better than nothing I guess. But still, why? :/

Everyone needs to read this. Reality is worse than anything we can say about these people in a few words, media appearances, op-eds, or other conversations. Read the whole thing.

On me dit que ce texte signé Spencer Baggins @bigaiguy a fort probablement été créé par IA.

Fabrice Bellard

A French engineer who lives quietly in Paris has spent 30 years writing software that the entire internet now runs on without knowing his name.

He wrote the code that streams every YouTube video, every Netflix show, every TikTok clip. He wrote the code that runs the virtual servers underneath AWS, Google Cloud, and Microsoft Azure. He calculated more digits of pi than anyone in history. He has no Twitter. He has no marketing. He just keeps shipping.

His name is Fabrice Bellard.

Here is the story, because almost nobody outside the systems programming world knows what one man has built.

Fabrice was born in 1972 in Grenoble, France. He studied at École Polytechnique, the top French engineering school. He never went to Silicon Valley. He never built a startup empire. He just wrote code.

In 2000 he started a project called FFmpeg, an open-source multimedia framework for encoding, decoding, and streaming video. He was 28. The project did one thing nobody else had done well. It handled every video and audio format that existed, in one library, on every operating system. He led it himself for years.

Today FFmpeg is the invisible engine of the internet. YouTube uses it. Netflix uses it. VLC uses it. Chrome and Firefox use parts of it. Every Android phone, every iPhone, every smart TV, every video editing tool you have ever touched runs FFmpeg somewhere underneath. If you have watched a video on a screen in the last 20 years, Fabrice's code processed it.

He was not done.

In 2003 he started QEMU, a machine emulator and virtualizer. He wrote it solo until version 0.7.1 in 2005. QEMU lets you run any operating system on any other operating system. It became the foundation of modern virtualization. KVM, the Linux kernel hypervisor, runs on top of QEMU. Every major cloud provider, AWS, Google Cloud, Microsoft Azure, IBM Cloud, runs virtual machines on infrastructure built around it. The Quick Emulator is the most cited piece of cloud infrastructure code on Earth.

He kept going.

In 2001 he won the International Obfuscated C Code Contest with a small C compiler that grew into TCC, the Tiny C Compiler. TCC can compile and boot a Linux kernel from source in under 15 seconds. In 2004 he calculated the most digits of pi ever computed at the time, using a personal desktop computer and an algorithm he derived himself called Bellard's formula. In 2011 he wrote a complete PC emulator in pure JavaScript that runs Linux in your browser, a project called JSLinux that engineers still cannot believe is real.

In 2019 he released QuickJS, a small but complete JavaScript engine that fits where V8 cannot. In 2021 he released NNCP, a neural network based lossless data compressor that immediately took the lead on the Large Text Compression Benchmark.

Then he turned his attention to large language models. He built TextSynth Server, a web server with a REST API for running LLMs locally. He released ts_zip and ts_sms, compression utilities that use language models to compress text and short messages at ratios traditional algorithms cannot reach. He released TSAC, a very low bitrate audio compression system. In December 2025 he released Micro QuickJS, a new JavaScript engine for microcontrollers, separate from QuickJS, designed for environments with almost no memory.

Fabrice co-founded a telecom company called Amarisoft in 2012, where he serves as CTO. Amarisoft builds 4G and 5G base station software used by carriers and labs around the world. He has been running it for over a decade while continuing to ship personal projects from his own home page at bellard dot org

He has no Twitter. He has no Instagram. He gives almost no interviews. His personal website is a flat list of projects with no styling, no fonts, no marketing copy. Just titles and links.

A quiet French engineer who never moved to Silicon Valley wrote the code that quietly runs the internet.

He is still shipping.

wait lemme get this straight

3 weeks ago digitalocean gets in the news for giving dhh's fash project $3m usd -- and now they're going around killing their other open source assistance program?

corporations are never your friends but this is still pretty terrible

As I was driving yesterday from Katwijk to Heidelberg, I didn’t have time to post about the successful second Earth flyby that ESA’s JUICE mission made on Monday, as part of its eight-year journey to Jupiter.

So here’s one of the images of Earth (& the Moon 🙂) from the JMC monitoring cameras, beautifully processed by my friend @stim3on: they’re not simple RGB devices, so lots of skill & knowledge go into getting a true-colour view 👍
