Whoa, congrats to Chainguard on the 2nd biggest partnership of the day!
Chainguard 🤝 @cursor_ai Our new partnership is making trusted OSS the foundation for AI-driven development. Now, devs using Cursor can pull from our CVE-free containers and malware-resistant libraries instead of public registries. See it in action 👇 chainguard.dev/unchained/cha…

There's something charming about watching claude build other agents. When you debug prompts and tool calls, you can almost see it empathize with the smaller, weaker agent.

some news; @latentpatterns 🤝 @chainguard_dev Chainguard will provide secure images for the embedded terminals within Latent Patterns. You’ll be able to run Claude code from within your browser. Zero api key provisioning or software installation. It just works, even on a Chromebook, from your browser... Thanks @lorenc_dan 🍻 ps. @chainguard_dev is hiring, and Dan mentioned employees get a near-unlimited budget for tokens...

Multicloud, my take on Gastown is alive, self-hosting, and cranking. Gastown showed me the future, this is my version of it. Check it out! github.com/dlorenc/multiclau…

Send help. I ignored all the instructions and used my Polecats with the Refinery. The Mayor and Deacon reported me to the Witness and the Sheriff is after me.

If working in OSS sometimes feels like running on a treadmill, then “done” software is the rare moment when the pace finally eases. By @lorenc_dan, thanks to @chainguard_dev thenewstack.io/put-a-fork-in…

The recent FFmpeg drama with Google is insane, and I'm surprised that so many people agree with FFmpeg's take on X. Google isn't even demanding FFmpeg's maintainer to fix the security bug. Are we living in a world now that sending LEGITIMATE bug reports is suddenly a sin?
I am the main developer fixing security issues in FFmpeg. I have fixed over 2700 google oss fuzz issues. I have fixed most of the BIGSLEEP issues. And i disagree with the comments @ffmpeg (Kieran) has made about google. From all companies, google has been the most helpfull & nice

Some actual facts here.
We’re excited to see the security and OSS communities engage on vulnerability disclosure in light of new AI technologies that we believe will enable both defenders and attackers alike. Existing and emerging norms around disclosure are important debates, and we’ve noted the feedback. Thanks! Also want to share some additional thoughts. 1/10

Tragedy of the commons is the dumbest, laziest, worst possible analogy for open source sustainability. Stop using this. Please. Everyone.
5 Nov 2025
Recently, there was a clash between the popular @FFmpeg project, a low-level multimedia library found everywhere… and Google. A Google AI agent found a bug in FFmpeg. FFmpeg is a far-ranging library, supporting niche multimedia files, often through reverse-engineering. It is entirely the result of volunteers and a marvellous piece of technology. For people who have never been on the receiving end of ‘security researchers’, it is difficult to understand why there is a pushback against them. Think about the commons. In Quebec, these are pieces of land where farmers send their cows during the summer. It is collectively owned, like FFmpeg. Everyone is responsible to care for the commons if they are using it. If you are not using it, you are supposed to stay away. Now, imagine a rich corporation comes in and sends its well-paid agents into the commons to find issues with it. Maybe a broken barrier or a dangerous hole. So far so good… But instead of fixing the issues, the corporation says “you have a month to fix the issue or else I will report you to the government”. How much love would the big corporation get in this context? Why do the security researchers insist on disclosing the issue without having contributed to fixing it? So that they can get credit for it. That's their entire scheme: find issues, irrespective of whether they affect the use case of their employer... after all, all issues no matter how small can be potentially significant at some point... and then brag about it without doing the hard work of trying to fix it. Let me be clear that no everyone working in security behaves this way. Many are good actors. But there are enough 'security researchers' behaving as parasites that it has become a recognizable pattern. « But Daniel, who should be fixing the bugs then? » If you are paying for commercial support, then get in touch with the folks you are paying. If you are not paying, then it is on you. It says so in the licenses. It is part of the moral code open source. It is part of the legal framework. Let me be clear. You do not get to bite back at Linus Torvalds if a bug in the linux kernel crashes your server. What you do is that you identify the issue, narrow it down and propose a fix. If you cannot do it, then you pay someone to do it. Or you just do not use Linux.

Please. Everyone. Stop using tragedy of the commons to describe open source. Just think about it first for like thirty seconds. It's the worst, wrongest, laziest analogy possible. I get it. But it's wrong.
This. Perfectly explained. Reporting issues in an open source project, without providing fixes, and then scaring to disclose the issue if not fixed within a small timeline is a d**k move. You cannot ask anything, if you are not paying for it.

Fun fact: at one point Google had an entire team building a new sandboxing technology just so they could run ffmpeg safely. Later it ended up being used in App Engine and other environments.

It looks like there is a $15k bounty out for an accepted PR that fixes the vulnerability identified by Big Sleep in @FFmpeg: bughunters.google.com/about/… I certainly didn't remember that this program existed, would be a different vibe to mention it in the bug report sent to project maintainers. Or would that not fit the rules of the program?
Google literally runs a program to pay people to fix bugs in critical OSS projects. Ffmpeg is explicitly in scope. Anyone can just send a fix and fill out a form and get paid. github.com/google/bughunters… This is all so dumb.

The year is 2037. Nix still hasn't decided on a path for flakes. @DeterminateSys just released Determinate Nix 23.0.
