A lot of attention is given to programming languages. Does it really matter what programming languages you know though? Many companies list positions such as “PHP Developer” or “Java Programmer”. Those interested in learning how to code often ask what language they should learn. MORE
To address this problem, we devised a Usability Testing Program — which, as a smaller company — presented us with some interesting challenges. Challenge 1: Not enough dedicated resources available to run the Usability Testing Program. MORE
Parallel programming solves big numerical problems by dividing them into smaller sub-tasks, and hence reduces the overall computational time on multi-processor and/or multi-core machines. In a previous post we have discussed the scaling of parallel programs. MORE
In the previous post we introduced the Pool class of the multiprocessing module. In this post we continue on and introduce the Process class , which makes it possible to have direct control over individual processes. A process can be created by providing a target function and its input arguments to the Process constructor. The process can then be started with the start method and ended using the join method. Below is a very simple example that prints the square of a number. MORE
