"I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu)..."
On August 25, 1991, a 21-year-old student sent a message to a Usenet newsgroup. He thought he was just building something fun for himself.
35 years later, that "hobby" is the backbone of global technology:
🚀 Powering helicopters in space with NASA
☁️ Running the global cloud and 100% of the world’s supercomputers
📱 Connecting billions of people
🎮 Redefining the future of handheld gaming
What started as one student's side project became the greatest collaborative technology movement in history. Thank you to every maintainer, contributor, and advocate who made it possible.
Happy 35th Birthday, Linux. Here’s to the power of open source and the next 35 years of building together.

Sad to see the @nytimes confuse open-source (fully transparent) with open-weight models (less transparent; no access eg to training data).
The new Meta model is open-weight but not open-source. NYT got it wrong.
It is time for both the media and the public to learn this distinction.

For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.
AI will transform every industry, power every company, and be built by every country.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.
The world needs both frontier closed models and frontier open models.

Open source is becoming central to how the AI stack is built and governed.
@ashimmy speaks with Duane O'Brien, Executive Director of the @OpenSourceOrg, about OSI’s role in defining open source since 1998 and why that work now extends into AI. The conversation covers OSI-approved licenses, the Open Source AI Definition, policy, education, and why AI systems require new thinking around openness.
