C on Linux or all of Java?

[Andrew McRobb]

Just from my experience in the C job market. It's usually firmware related
jobs which means you also need knowledge of MCUs like Microchop/Atmel/ARM,
etc. If I was in your shoes I would pick up Go or Rust. (A LOT of
projects/companies are going in this direction) Go is basically C and
Python. I've been a long time PHP programmer and after using Go I haven't
looked back at PHP since. I know PHP introduced Composer and some other
things, but I feel like it's going the way of Zend making shit more bloated
then it needs to be, but that's my two cents.
