In that folder I put /foo/program.py. I run program.py and program.pyc is created. I have *.pyc in the .gitignore file, so git doesn't track it. Now let's say I make anoth...
I have an "appliance" (for lack of better description) running linux. Currently I ssh into the box to launch jobs. This isn't friendly enough for my users, so I'm putting together a simple web UI to launch the script. A job runs for anywhere from 10 seconds to several hours.

There's so many languages related to web development and programming in general. I had might as well add Ruby to the question. Java, Python, or stick with PHP and try to really master it? For those of you program...

On the server, the Python 2.6 "json" module tries to loads() the JSON, but it's choking on some combination of backslashes.
