Worked for ten years in a military setting, old (now obsolete) MIL-STD-2167, Jovial (which preceded Ada). I went to academia/research for fifteen years,(some OS mostly CV), then went back to do some real work.

Care about reliability, and readability of code. Though my work was mostly C/C++ (Jovial, Pascal, Fortran, Assembly, and, when needed object code as well - a lot of) - Ada, which I am still learning, is by far my preferred language.

Not a fan of meta-programming (very powerful, but a "write-only" practice used mainly to add features to the language that should have been implemented by the compiler in the first place)

Not a big fan of Agile either (If it was hard to write, it should be hard to understand)
