While it’s generally considered to be bad practice to import everything into the global namespace, I think it’s fine to do this in an ad-hoc environment such as a notebook as it ma…

I wanted to share with you a cheatsheet I made for Plotnine, a data visualization package for Python. I've probably never spent so much time on just two pages, even with the ggplot…

You can probably get these sets second hand. I just revived a bricked one (hah!) myself. Had to use the Lego software to update the firmware for that, which only runs on Windows 7,…

Author here. Worth pointing out that the discussion from Sept 19 2013 is actually about a blog post, which predates the book. It's because of the amount of feedback it got on HN th…

I also thought it was made with TikZ (which is a compliment). I used TikZ for my thesis: https://jeroenjanssens.com/phd/ and same thing here, the code is a mess.

My book Data Science at the Command Line has a chapter about this that scratches the surface and lists some resources in case you want to dive deeper [1]. I can also recommend chec…

I often use csvquote [1] whenever I need to process CSV with a command-line tool that doesn't support it. For example: csvquote test.csv | awk '{print $1, $2}' | csvquote -u [1] ht…

Author here. Without HN this book probably wouldn't have existed. In 2013 I wrote a blog post that received quite the attention here [0]. Because of that I got the idea to expand i…
