I'm friendly, I think. Guys generally are doing good job, and I appreciate that. Period.
I'm a little bit angry at myself that I haven't learned Python and Linux in depth when I had time for that. And there were few opportunities back then. Now you know, kids, schools, ...life happened in the meantime. So, few hours a week for Python at night after whole day... Doable, but... getting from basic training to actually being able to solve issues will take me 5-10 years.
