Of course don’t just ask the engineer. Any piece of code written by the engineer should ultimately be tested by a separate testing team before getting pushed to production. Ideally you have a performance and regression testing team that would help evaluate the changes being introduced and how it compares with the existing.

There are ways to know. Did the manager ask for proof of concept? Asked for performance tests of the update and compared it to existing/baseline?

Technical managers exist. Yes, it’s a manager’s responsibility to understand the field he’s working in. He doesn’t need to be a more skilled engineer, but he needs to understand what his/her people are saying.

Fire the manager too.

Yes, but more competent, not cleverer. Some managers aren’t fit to be in IT.

For almost 20 years, I’ve never lost hours of work due to the OS. The Crowdstrike incident was one of three times I was interrupted by the OS in the last 2,3 years. All of the interruptions are from Windows 11, not 10. This week for, for some reason, Windows is slower to respond than usual, when going to different tasks. I’m one formatting away from getting rid of the Windows 11 in my laptop. I was thinking of dual booting Mint there but it’s looking more and more I don’t need Windows. Bazzite has been fantastic.
