I hadn’t realised that Data Braider is now free for #MSDyn365BC If you’ve ever bemoaned the very basic APIs that are available out of the box in BC, it’s the extension for you Thanks @bc.jeremy.vyska.info and @stefanmaron.com

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...

well, in python 0 is the first -1 the last. 🤷‍♂️

Stefan Maron | #msdyn365bc MVP @stefanmaron.com · 08/04/2025

-1 would be the last -2 the second to last and so on Thats how it is in python. Right now we need to count the list to get the last item. stackoverflow.com/questions/93...
