Currently Python. Love it. Wish only that I were better at it.

I have been falling in love with Go (golang). I enjoy their approach to concurrency/async.

Hello from X11 land! As I do not work as a programmer most of my projects are hobby projects just for me or small scripts so I mostly use python, c, bourne shell and plan9 rc. As for the languages I’d like learn I must say haskell and 32 bit x86 assembly. I know a bit of haskell but not nearly enough to write anything really and with x86 assembly I’m stuck on the real mode. Well that is what you get when you learn programming on DOS :P

Mainly PHP, Javascript (now heavily laden with jQuery) and some Ruby in day job.

Learning Android programming (along with diving back into Processing, a fusion of Art and Java programming, and also has “Android” and “Javascript” mode for quickly generating code that runs on those devices/platforms) in spare time…

Have a book on Go programming that I barely dented, and would like to plunge more into Node JS, at least in terms of single-page web apps and some CLI utility ideas…

I currently use ruby for work, with a side dose of perl (my go-to hack tool if I need something quick and dirty). Very new to all of the meta-programming stuff, which my tech lead is very good at, so I’m kinda hanging on for dear life there.

I would love to learn more javascript though. I hacked a simple task tracker using the meteor framework, but required tons of help.

Java would be my go-to if someone said “Hey, go code this thing”.

I need to learn Perl before arriving at a Perl-heavy job.

I am now interested in Scala; Java but sane and minus the boilerplate would be nice.

Mostly Perl and a bit of Python and bash here and there. Recently I tried newLisp (http://www.newlisp.org) in a couple of reporting tools and I already in love with it.

In my day to day i program in MUMPS (cache intersystem) and Python when i need to make quick scripts for general purposes.

I have tried Haskell (two weeks ago), and i have to recognize that it is very hard to me to change the way of making things… Too much for someone who began with Fortran IV, Pascal, turbo c, assembly

That sounds great! I haven’t managed to make it work with my Maven-Scala-Android setup yet, but I’ll keep on trying, because if this works this’ll save me so much time waiting for compilations to finish! Some part of me still wonders what’s going on with the Java executable for it to take so much time on startup…

In current practical use, Java and JavaScript are JITed so they’re also compiled to native code. With HotSpot, Java is about as fast as C++ and is faster than Haskell’s GHC. CPython is slow, GILed, and only byte-compiled but several other Python platforms have a JIT compiler.

If I really have to think in terms of speed, I usually use C. Yes, CPython is slow as hell as soon as you start using low-level constructs (for loops over numerical arrays in particular) and it sure has the GIL ; the Python language is, however, great as a scripting and general high-level language. The JVM may be fast, but I’m usually avoiding it because of the time it takes (maybe that’s just me?) to even start the “java” command…

However, I recently did a lot of heavy JavaScript rendering on Canvas2D, and I was really surprised at how fast it was. Depending on what you do, with well-written code, you can get quite close to C speeds, which is amazing for a scripting language!
