Very useful spatio-temporal analysis tools within the python / jupyter ecosystem.

Can do all sorts of spatial analysis and visualization, but also more specific things like spatial inequality computation (using e.g. Theil index, Gini, ...).

If you're a collective or a (grass-roots) organization, this software might make organizing joining and membership, broadcasting messages and tracking identities easier.

One of the most useful cli JSON AND YAML viewers, certainly one of the prettiest.

Vim-like movement, regex search, collapsible sections, syntax highlighting of course, yadda yadda..
