A strangely satisfying benefit of being on vacation is that I have some spare time to prove people wrong on the internet.

Workflow security continues to be a common cause of compromises of open source projects.

If you're using GitHub Actions and don't want this to happen to your project: use Zizmor and treat the findings seriously, especially insecure triggers and user-controllable template injections.

After 13 years of building Discourse in public, we're excited to announce: we're staying open.

Discourse has always and will always be open source.

Here's why.

Discourse is Not Going Closed Source

Beim GNU/Linux-Podcast spreche ich über Software-Lieferketten, SBOMs u.v.m. im Kontext der Deutschen Bahn. Also nicht nur, was das ist, sondern wie wir damit auch sinnvoll umgehen können und was das mit Engagement in Open-Source-Projekten zu tun hat.

Today at 10:00 @ #FOSSbackstage, my colleague @cschum and I are going to talk about "getting real with the supply chain". The session will be about how the #OSPO at #DeutscheBahn generates actionable insights from vast data and navigates the triangle of risk/value/people.
