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.
JUNKYARD KING ⚔️ EP1 - "Training Day"
Here’s what I learned making the latest episode of my 80s-inspired action-adventure fantasy buddy comedy about a kid, a glowing sword, and a mechanical crow.
A thread 👇
Anthropic published a security guide that basically tells you to stop trusting your own AI agents.
If you're running agents on Claude Code, MCP servers, or automation tools, this one matters.
Here's what it actually says: 👇
🎨 FRACTAL HOLOGRAPHIC KALEIDOSCOPE 🎨
Prompt :
A Fractal Holographic Kaleidoscope centered around [SUBJECT]. Infinitely repeating patterns and holographic foil textures create a dazzling, symmetrical display, with colors morphing between [COLOR1] and [COLOR2].
Check ALTS
I made a second version!
This time, I improved the opening to make it more eye-catching, added extra padding to the character shots so the video won’t get cropped across different social platforms, and updated the prompt into English.
I also improved the canvas workflow. Previously, I had to generate multiple images and videos one by one, then pick the best results. Now the canvas supports generating multiple results in a single run, which has greatly improved my workflow efficiency.
Now you only need to swap the image, and the same video prompt can still produce great results.
Which anime cosplay should I make next?

20-min Demo
AI Animated Film experiment (full feature is 90 mins)
With a $500 budget and 1.5 months of work, this story is based on my original idea from 2010... and today, the technology is finally ready to bring it to life.
AI showed me that solo creators can now manage an entire animation workflow. No need to pitch to big studios—you can fund yourself and bring your own stories to life. Without AI, this would still be stuck in my head.
(Of course, the quality is still far from high-budget films from big studios that have 300-600 people behind them, but I think the gap will close step by step in the future.)
This animated created by Seedance 2.0 on @dreamina_ai and @kinovi_ai and opening scene by @midjourney - thank you for watching.
Claude is now your real estate marketing agency.
Analyze listings from Airbnb, Booking, Zillow or Expedia, then build the assets owners never had. 3D tours, a clean site, photos that sell. Pitch the owner and get paid. Higgsfield MCP is the key.
Then scale to the next owner.
this OpenClaw bot finds businesses the day they register, builds their whole brand, and mails the owner a postcard with it, on autopilot...
here's how agencies can land recurring clients with this system:
- scans public business registrations the moment they're filed
- filters for the ones most likely to become real, spending businesses
- pulls the owner's name + address direct from public records
- generates a full website for their exact business, live at a URL
- creates a matching logo, brand kit & ready-to-run ads
- sets up their google business profile + a snapshot of local competitors
- prints a personalised postcard with their whole brand already built + QR code
- mails it to their door, addressed to the owner by name
every step from registration to outreach is automated.
reply "SYSTEM" + RT and i'll send you the full breakdown so you can build this too (must be following so i can DM)
