Open source projects: consider running office hours

Back in December I decided to try something new for my Datasette open source project: Datasette Office Hours. The idea is simple: anyone can book a 25 minute conversation with me on a Friday to talk about the project. I’m interested in talking to people who are using Datasette, or who are considering using it, or who just want to have a chat.

Weeknotes: Finally, an intro video for Datasette

My big project this week was this Video introduction to Datasette and sqlite-utils. I recorded the video a few weeks ago in advance of FOSDEM, but this week I put together the annotated version. I’m really happy with it, and I’ve added it to the datasette.io homepage as a starting point for helping people understand the project.

Here’s the video, plus annotated screen captures with further links and commentary.

I also released download-tiles for downloading tiles and bundling them into an MBTiles database.

Serving map tiles from SQLite with MBTiles and datasette-tiles

Working on datasette-leaflet last week re-kindled my interest in using Datasette as a GIS (Geographic Information System) platform. SQLite already has strong GIS functionality in the form of SpatiaLite and datasette-cluster-map is currently the most downloaded plugin. Most importantly, maps are fun!
