I have never seen platform reliability take a nose dive in quite the same way as GitHub recently. Practically every day I'm dealing with an outage on actions, webhooks, PRs, etc. Some products seem untouchable in terms of competition until they aren't.

This is heartbreaking and cruel. I'm not going to pretend Scouting America has been perfect, but they really started to turn the page the last few years with better training and policies. Please stop using my kids as political pawns.

I haven't used Windows for development in a minute (ok, decade). So far I'm surprised that most of the tools I want to use are available! Outside of the new terminal app, winget and oh-my-posh, are there other Windows-specific tools I should be looking into?
