Prologue This week, Kim Lewandowski joins Rafal & James to talk about Google's latest contribution to the Open Source software movement - Supply-chain Levels for Software Artifacts (SLSA). We have a great conversation, and I hope you guys go watch the video (when it comes out) and check out the axe in the background. I never did find the interesting logo Kim talks about- maybe one of you will find it and post it to #DtSR on Twitter!
