“Public money flows around Open Source instead of into it. Governments should contract with Open Source maintainers and builders, not middlemen who merely resell it.” https://dri.es/funding-open-source-for-digital-sovereignty

What a great post from @opensourcepledge member Zerodha, who are giving $1 million to Open Source projects. 🙏 “FOSS projects that the world depends on ought to receive financial backing as the norm, [and] collective societal recognition is owed to maintainers.” https://floss.fund/blog/second-tranche-2025-anniversary/

I tried to go for a full day without using Open Source software. It didn&#39;t go well. https://www.youtube.com/shorts/ybxobfBme_0

Tailwind CSS&#39;s business model went away overnight — partly because LLMs are accelerating the Open Source sustainability crisis. I wrote a post about how LLMs popularise projects while simultaneously financially harming their creators. Yet another reason for companies to join the @opensourcepledge. https://vlad.website/llms-are-accelerating-the-open-source-sustainability-crisis/ (For filters: #opensource #ai)

So freaking excited to launch the Open Source Pledge!!! Companies rely on the work of Open Source maintainers. Those maintainers should get paid, and we&#39;re celebrating the companies who do the right thing. Fediverse friends, tell your employer to #paythemaintainers!

Anthropic, makers of Claude, have published a report saying that “AI use impairs conceptual understanding, code reading, and debugging abilities, without delivering significant efficiency gains on average”; for Claude Code specifically, they expect even “more pronounced” impacts on learning https://www.anthropic.com/research/AI-assistance-coding-skills (filters: #ai)

Here&#39;s my FOSDEM 2026 talk about phantom binary dependencies 👻 — software packages we depend on without realising it, which leads to security and sustainability issues. https://www.youtube.com/watch?v=fP8OFI5PdBI

We need better tools for uncovering phantom binary dependencies. Not having these tools makes our global tech infrastructure less secure, and puts a strain on the Open Source maintainers we rely on. I collected some resources on this topic in this new post. https://vlad.website/binary-dependencies-identifying-the-hidden-packages-we-all-depend-on/

“Sovereignty is not about where a company is headquartered or where software was originally written. It is about who ultimately controls the technology. The right question to ask about any technology: can someone take the software away from me?” https://dri.es/the-software-sovereignty-scale
