    I love such stories. Right now, a lot of folks I know are struggling to find jobs, so I read the part about how he got a job the first day he was out of jail with some astonishment…

    Well, I'm on Windows (+ Cygwin) and wrote a Dockerfile. It wasn't that hard. git branch + worktree + a docker container per project and I can work with copilot in --yolo mode (or c…

    I have this one https://www.sordum.org/9470/windows-update-blocker-v1-8/ I will check out the Chris Titus link someone else posted below, too, but that seems more risky.

    It's become a universal truth that you should probably not upgrade to the latest and non-greatest version of ANYTHING these days. Not Android, not Windows, not iOS, not macOS. It's…

    I took care of IT for a startup hedge fund once. I was the quant's right-hand man, data engineer, visualization dashboard guy, everything. The quant needed to run a monolithic C++ …

    They're great at creating test cases out of code and/or log file excerpts. They're good at run-of-the-mill tasks whose answer one can reasonably expect to find on StackOverflow. I'…

    Yes! Once I've figured out that this problem is best solved using parser combinators, and that I have a good idea of how to model the transformation, I'm so glad I can delegate wor…
