PAGNIs: Probably Are Gonna Need Its
Luke Page has a great post up with his list of YAGNI exceptions.
[... 1,289 words]sqlite-plus (via) Anton Zhiyanov bundled together a bunch of useful SQLite C extensions for things like statistical functions, unicode string normalization and handling CSV files as virtual tables. The GitHub Actions workflow here is a particularly useful example of compiling SQLite extensions for three different platforms.
Git scraping, the five minute lightning talk
I prepared a lightning talk about Git scraping for the NICAR 2021 data journalism conference. In the talk I explain the idea of running scheduled scrapers in GitHub Actions, show some examples and then live code a new scraper for the CDC’s vaccination data using the GitHub web interface. Here’s the video.
[... 289 words]Blazing fast CI with pytest-split and GitHub Actions (via) pytest-split is a neat looking variant on the pattern of splitting up a test suite to run different parts of it in parallel on different machines. It involves maintaining a periodically updated JSON file in the repo recording the average runtime of different tests, to enable them to be more fairly divided among test runners. Includes a recipe for running as a matrix in GitHub Actions.

Git scraping: track changes over time by scraping to a Git repository
Git scraping is the name I’ve given a scraping technique that I’ve been experimenting with for a few years now. It’s really effective, and more people should use it.
[... 963 words]Weeknotes: airtable-export, generating screenshots in GitHub Actions, Dogsheep!
This week I figured out how to populate Datasette from Airtable, wrote code to generate social media preview card page screenshots using Puppeteer, and made a big breakthrough with my Dogsheep project.
[... 1,461 words]California Protected Areas Database in Datasette (via) I built this yesterday: it’s a Datasette interface on top of the CPAD 2020 GIS database of protected areas in California maintained by GreenInfo Network. This was a useful excuse to build a GitHub Actions flow that builds a SpatiaLite database using my shapefile-to-sqlite tool, and I fixed a few bugs in my datasette-leaflet-geojson plugin as well.
Announcing the Consortium for Python Data API Standards (via) Interesting effort to unify the fragmented DataFrame API ecosystem, where increasing numbers of libraries offer APIs inspired by Pandas that imitate each other but aren’t 100% compatible. The announcement includes some very clever code to support the effort: custom tooling to compare the existing APIs, and an ingenious GitHub Actions setup to run traces (via sys.settrace), derive type signatures and commit those generated signatures back to a repository.
Doing Stupid Stuff with GitHub Actions (via) I love the idea here of running a scheduled action once a year that deliberately fails, causing GitHub to send you a “Happy New Year” failure email!
zhiiiyang/zhiiiyang profile README (via) This is a brilliant hack: a GitHub profile README that uses an action to retrieve the author’s latest tweet (using R), render it as a PNG screenshot in headless Chrome via rstudio/webshot2 and embed that image in their profile.
Building a self-updating profile README for GitHub
GitHub quietly released a new feature at some point in the past few days: profile READMEs. Create a repository with the same name as your GitHub account (in my case that’s github.com/simonw/simonw), add a README.md to it and GitHub will render the contents at the top of your personal profile page—for me that’s github.com/simonw
GitHub Actions: Manual triggers with workflow_dispatch (via) New GitHub Actions feature which fills a big gap in the offering: you can now create “workflow dispatch” events which provide a button for manually triggering an action—and you can specify extra UI form fields that can customize how that action runs. This turns Actions into an interactive automation engine for any code that can be wrapped in a Docker container.
A cookiecutter template for writing Datasette plugins
Datasette’s plugin system is one of the most interesting parts of the entire project. As I explained to Matt Asay in this interview, the great thing about plugins is that Datasette can gain new functionality overnight without me even having to review a pull request. I just need to get more people to write them!
[... 914 words]Using a self-rewriting README powered by GitHub Actions to track TILs
I’ve started tracking TILs—Today I Learneds—inspired by this five-year-and-counting collection by Josh Branchaud on GitHub (found via Hacker News). I’m keeping mine in GitHub too, and using GitHub Actions to automatically generate an index page README in the repository and a SQLite-backed search engine.
[... 1,100 words]Tracking FARA by deploying a data API using GitHub Actions and Cloud Run
I’m using the combination of GitHub Actions and Google Cloud Run to retrieve data from the U.S. Department of Justice FARA website and deploy it as a queryable API using Datasette.

GitHub Actions ci.yml for deno. Spotted this today: it’s one of the cleanest examples I’ve seen of a complex CI configuration for GitHub Actions, testing, linting, benchmarking and building Ryan Dahl’s Deno JavaScript runtime.
