Rlang ☛ Designing monochrome data visualisations
First of all, let’s start with a definition of what we mean by monochrome (or monochromatic). Creating a monochrome chart essentially means only using different shades of one colour. In most cases, this means different shades of grey (or black and white) which, can also be termed greyscale. The examples in this blog post will all be relating to creating charts using only black, white, and grey. However, you should find some of the advice useful if you ever need to make monochrome charts with a different colour.
There are several different reasons why you might need to make monochrome visualisations. A (frustratingly) common one is that some academic publishers still require versions of plots to be submitted in black and white. Another reason might be to improve accessibility – if a plot is understandable in greyscale, it’s much more likely to be colourblind-friendly. It also has the added benefit of preserving the colour representations in your charts for people who like to print out documents (and save money by not using colour ink)!

University of Toronto ☛ The practical (Unix) problems with .cache and its friends
If you haven't noticed, there are an ever increasing number of programs that will cache a bunch of data, sometimes a very large amount of it, in various dot-directories in people's home directories. If you're lucky, these programs put their cache somewhere under ~/.cache; if you're semi-lucky, they use ~/.local, and if you're not lucky they invent their own directory, like ~/.cargo (used by Rust's standard build tool because it wants to be special). It's my view that this is a mistake and that everyone should put their big caches in a clearly visible directory or directory hierarchy, one that people can actually find in practice.
