I've converted three more Software Carpentry lectures to chapter format, bringing the total to four:
- the shell
- number crunching with NumPy
- regular expressions
- software engineering
It's all CC-A licensed, and yeah, the images could be a lot better: they're just screen captures from the original PowerPoint slides, because re-doing them as SVG felt even more like yak shaving than converting the text. Please let me know if this is useful.
