I...

Scalable web application with lot of image servings
I started working on a web application. This application needs lot of image handling. I started off with PHP as it was the easiest and cheapest to host.

Resize ctypes array
I'd like to resize a ctypes array. As you can see, ctypes.resize doesn't work like it could. I can write a function to resize an array, but I wanted to know some other solutions to this.

Programming with hardware in python
I am starting to get a bit bored of programming little toys that I have been making recently, and I would love to starting programming and interacting with hardware.

I would like writeLog() to be able to add something to the message to identify which thread is ca...

When to use While or the For in python
