I use Hugo for static site generation and it makes the RSS stuff for me.

That’s a tough question and I don’t really have am answer.

But if it’s work related I’d look into finding a Windows SysAdmin course somewhere and ask my employer to pay for it, since it helps with your work.

A cheaper alternative would be online courses. I found Udemy quite helpful in that regard.

Another possibility is Microsoft Learn, which offers basic to professional “Learning paths” you can do on your own time. There’s also a SysAdmin certification available if I recall correctly.

Edit, since I just reread your post: Microsoft Learn is almost completely about Azure. So you should really take a look at it.

Recently switched jobs from maintaining a 15 year old Windows Forms .NET Framework legacy codebase.

At the new job we stick to Clean Architecture, use unit and integration tests, have a code generation tool, actually make nice use of generics and use dependency injection. Also agile processes, automatic build tools, whatever. The difference is night and day and I’m so glad my ex boss fired me because I told him he’s an asshole and his codebase is shit.
