A wee story, back in the early days when aws was S3 and EC2 and pretty much nothing else. I left a VM running for a month. 400 dollars. My fault totally. I posted on twitter (back in the day) something along the lines of "nothing like a 400 dollar bill to remind you of a running VM."

Today I'm releasing AotAnywhere, a package which enables cross platform publishing support for dotnet NativeAOT. Before this package you had to use multiple different runners, with AotAnywhere you can publish for all targets from any single host. This is continuing the great work of @migeel.sk
Graphic showing all supported environments to build on, and all supported environments the resulting binary can run on.

It’s probably not a very popular opinion but teamwork requires a disproportionate amount of effort compared to solo work. Communication overhead, differences of opinions, alignment, etc. suck so much energy out of the individual experience. It’s rare to read up on any of that.
