I interact with alot of programming languages on a frequent basis..
C/C++ when I need speed,
Java when I need to satisfy my stupid clients,
Pyhton when I want a language that doesn't have curly brackets (and don't have clients complaining 24/7 by my ears),
Perl when I need to write some scripts that does something simple and I don't feel like spending a whole week writing the highly optimized 10k lines of code equivalent in C++.
C++ still gets my vote tho, speed is mostly what my software is targeted at.
I don't submit to the philosophies of some language(s) that is worse than code from the IOCCC and thedailywtf.com mixed with a little bit of code added from an entry-level programming class with people of IQ 0 in it that somehow compiles and run (while bringing down the entire server in the process). (do you know that I am mentioning MUMPS?)
