Following on from the C++ collections post, it’s time to create a similar overview page for Python! There are more collection classes than this, but I wanted to revise the basics.

Running a Code Jam

Recently, a number of teams at work have started to make use of Docker. To improve our Docker knowledge across the company, we organised a Code Jam. We’ve run a number of these events in the past and, after some experimentation, we’ve settled on a format that seems to work well for us.

Simple Rotation Matrices

Rotation matrices can be built by combining basic rotations in X, Y and Z (see Wikipedia), but it’s also possible to describe them by setting values in the matrix directly. I’ve recently found this useful as a quick way to create a matrix to convert from a space where the X and Y axes are flipped.
