Starting today, the way you will build infrastructure automation is AI Native. You'll prompt the agent, and then System Initiative will get to work building your automation for you in a safe, simulated change set. Come try it - it's so fun. www.systeminit.com/blog/ai-nati...

When people ask me why I'm excited about LLMs for programming when the productivity increase might reduce demand for programmers I remind them I've been contributing to open source for 20+ years with the exact goal of making other programmers massively more productive

It’s very sad to see the end of Go Time. I had a fantastic time doing it. I learned so much, and got to meet so many great people. We had a lot of fun, and a lot of credit goes to the other hosts and the team behind the scenes. Changelog make fantastic podcasts and I can’t wait for what’s next.
