That depend of how you define simple. If it's just a couple of lines of code calling some libraries, the libraries being written in C and compiled, the python interpreter will spend most time calling the c functions, and rewriting the code in c or c++ is using the libraries natively, will only take the time for the linker to load the symbols if they are shared. And in python it will take mostly the same time, neglecting the interpreter overhead. But if the whole functionality is reimplemented, it will probably be statically linked and be probably faster than ten times faster, because of cache.

I'm not saying everyone needs a fast language, but porting Fortran to Python in order to optimize it probably won't be too successful :)

It's occurred to me that one of the more powerful projects I could do from a fiscal perspective would be to write a blazingly fast Python interpreter without a GIL.

I'm learning how to use Java. Also know bits of Matlab too. I'm fairly new to this though.

I usually program with Java, C++, Ruby, Python, C# or PHP. I've also been programming in Haskell and Basic many years ago. I can also work with most modern databases.

I focus on web application development, and I know most of the usual stuff there too, even though they're not really programming languages: HTML 4.01/5, XHTML, XML, CSS 2.1/3, JavaScript. Also Dart if it's worth mentioning ;)

python, fortran, c++

We use fortran at school, apparently there is a ton of legacy code around and its been the target of the largest optimization project ever. I still haven't noticed much of a difference in speed between even python and fortran. Python is ridiculously easy, so I mostly use python.


Hey - try this: http://speed.pypy.org/

Perl, Python, and the rare rare rare Pascal.

C programming, GTK2.xx(GUI programming), Awk, NASM(netwide assembler). I tinker with python, Sed, JS. I've tried a bunch of languages.

Currently, I use C, C#, SQL, vbscript, XML, and reading various micro-controller assembly languages via the C compiler output listings. Occasionally I use Java. Most of my undergrad used Ada. I've used many other languages over the years.

Java, but I have been messing around with scripting languages like python just for kicks!

Hmm, lets see here..
HTML, CSS, Javascript, PHP, C#, Java, Lua and a little C++...and also SQL if that counts.

There are some windows only programs that use Delphi. For portable programs (which sometimes started out as Delphi) and for embedded processors I use C. For web pages Javascript (my least favorite). Used to do quite a bit of PIC assembly language but fortunately those days are gone.
