This is the first open source package registry to create a commercial operation for large company users to help fund the registry. We discuss how we got here, what's actually going on, and why this commercial approach is working. Everyone knew this day would come, and it looks like the Eclipse Foundation got this one right.

Josh welcomes back François Proulx to talk about the absolute madness in the CI/CD universe right now. We also learn about François' new project SmokedMeat which is a tool to help you hack your own CI/CD. When Josh spoke to François a year ago, the world was a very different place than it is today. François has a ton of knowledge about how we got here and what we can do moving forward. Boost Security has a bunch of amazing open source tools François built that can help keep CI/CD systems understood and locked down.

Josh chats with Sal Kimmich about the current state of everything, and what we can expect next. Sal has some incredible insight into what we can expect to see due to the current wave of security bugs and incidents. There are some new features we will need in both our hardware and software to ward off the state of things. Since those features are years away, what we need in the short term is shoring up our SDLC programs. Sal has some really good medical examples and analogies for this one. It's a huge problem but not insurmountable.

Josh talks to Casey Ellis about why vulnerability disclosure is so hard, and also so important. Casey is one of the best in this space having been a Bugcrowd founder. There are few people with more experience and insight into how a security vulnerability should be handled, and why the explosion of AI is making all this much harder than it's ever been before. While finding vulnerabilities is easy, reporting them is still a lot of work. Casey is working on helping everyone better understand all this with his disclose.io project.

Josh has a discussion with Vlad-Stefan Harbuz about the Open Source Pledge as well as his recent FOSDEM talk. The Open Source Pledge is all about trying to build a sustainable universe for open source maintainers. This ties into Vlad's FOSDEM talk which was all about the challenge of just knowing what open source you are using. The importance of trying to make open source sustainable is a really important topic, but it's also a really hard topic. Vlad helps explain all of this as well as some ideas for the solving this in the future.

Josh welcomes back David Bernstein to talk about creating a disaster recover plan. It's a very timely topic given all the current events. There are more supply chain attacks and compromises than ever before. There are some great resources for this planning, but as David tells us, it's really not that hard to put some plans together. It's easy to over-plan, David gives some great tips on getting started with our planning for an eventual incident.
