What language(s) do you use? Why?
I use a lot of languages, for different reasons, for different purposes. My go-to language is Clojure, because it is a functional lisp, that is practical to use. I love lisps, and functional programming, so for me, Clojure is a match made in heaven. At work, I use Go, Python, a bit of Ruby, JavaScript and shell, because these were the best at the time, within a given environment, for the task we needed them for. For fun, I dabble in Hy (a lisp that compiles to python AST). I used to do a lot of C, but thankfully, I do not have to anymore.
Do you use an IDE or do you hate IDE's?
I use Emacs, which is, for me, far superior to any IDE. But I do not hate IDEs, they're just not for me.
What languages do you hate with passion?
PHP, because in a previous life, I was trying to integrate it into a webserver, and had to look at its source, and that was a horrendous experience. Years later, at another job, we found serious bugs within some of the standard stuff that ship with PHP, still unfixed to this day. It is a terrible language. Every time you'd want to use PHP, there is always something better, more fit for the job.
I also dislike C a lot, because I wrote far too much in it, but perhaps, not with a passion.
I do hate all OOP languages, apart from SmallTalk. They are all awful.
