Online code execution
There are some websites that allow online code execution:
- Lua-demo : just Lua, with some canned demo-programs.
- CodePad.org : C C++ D Haskell Lua OCaml PHP Perl Python Ruby Scheme Tcl
This can also be used to share/discuss code, much like PasteBin.com.
- CompileOnline.com : lots of programming-languages
- ideone.com : Online-Compiler
...
This allows for a quick test of (short) programs/scripts, without the need to install something on the own machine.
