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.

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. # 21st August 2020, 11:15 pm

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. # 19th August 2020, 5:48 am

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! # 25th July 2020, 9:19 pm

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. # 11th July 2020, 5:47 pm

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. # 7th July 2020, 4:33 am

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!

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.

I released a fun little Datasette utility today: datasette-clone.

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. # 18th December 2019, 8:49 am
