Going live on YouTube. Taking a real published AppSource extension and asking: how good can AL code actually get? Running the analyzers, walking through the findings, exploring what ISO 5055 reveals that most of us never think about. 👇 youtube.com/live/JI5KlMx...

One Sunday afternoon playing with my daughter, I wondered: what if you could run AL tests directly — without a container? A few weeks later: AL Runner. 3,400 test cases. ~30 seconds. Big thanks to Steve Endow, @dvlprlife.bsky.social, @bc.jeremy.vyska.info and more! 👉 stefanmaron.com/posts/al-run...

Claude Code refused to escape its sandbox. Framed the same goal as "fix the firewall blocking my push" and left it running. It ran the script — re-applied the default rules, cut off its own API connection. Locked itself out for 7 minutes. stefanmaron.com/posts/claude...

How can just in time loads be faster than a full record load? After all, this means two queries reading the same table. And two are slower than one, right? Right, but only if we allow these two queries to run until completion. www.keytogoodcode.com/post/jit-loa...
