Practical campaign security is a wood chipper for your hopes and dreams. It sits at the intersection of 19 kinds of status quo, each more odious than the last. You have to accept the fact that computers are broken, software is terrible, campaign finance is evil, the political parties are inept, the DCCC exists, politics is full of parasites, tech companies are run by arrogant man-children, and so on.

Los Angeles Weedmaps analysis (via) Ben Welsh at the LA Times published this Jupyter notebook showing the full working behind a story they published about LA’s black market weed dispensaries. I picked up several useful tricks from it—including how to load points into a geopandas GeoDataFrame (in epsg:4326 aka WGS 84) and how to then join that against the LA Times neighborhoods GeoJSON boundaries file. # 4:35 am

Building a stateless API proxy (via) This is a really clever idea. The GitHub API is infuriatingly coarsely grained with its permissions: you often end up having to create a token with way more permissions than you actually need for your project. Thea Flowers proposes running your own proxy in front of their API that adds more finely grained permissions, based on custom encrypted proxy API tokens that use JWT to encode the original API key along with the permissions you want to grant to that particular token (as a list of regular expressions matching paths on the underlying API). # 4:28 am

datasette-jq (via) I released another tiny Datasette plugin: datasette-jq registers a single custom SQL function, jq(), which lets you execute the jq expression language against a JSON column (or literal value) to filter and transform the JSON data. The README includes a link to a live demo—it’s a neat way to play with the jq micro-language. # 1:52 am
