Weeknotes: SpatiaLite 5, Datasette on Azure, more CDC vaccination history
This week I got SpatiaLite 5 working in the Datasette Docker image, improved the CDC vaccination history git scraper, figured out Datasette on Azure and we closed on a new home!
[... 986 words]The Accountability Project Datasettes. The Accountability Project “curates, standardizes and indexes public data to give journalists, researchers and others a simple way to search across otherwise siloed records”—they have a wide range of useful data, and they’ve started experimenting with Datasette to provide SQL access to a subset of the information that they have collected.
Weeknotes: Datasette and Git scraping at NICAR, VaccinateCA
This week I virtually attended the NICAR data journalism conference and made a ton of progress on the Django backend for VaccinateCA (see last week).
[... 773 words]Trying to end the pandemic a little earlier with VaccinateCA
This week I got involved with the VaccinateCA effort. We are trying to end the pandemic a little earlier, by building the most accurate database possible of vaccination locations and availability in California.
[... 1,154 words]Fuzzy Name Matching in Postgres. Paul Ramsey describes how to implement fuzzy name matching in PostgreSQL using the fuzzystrmatch extension and its levenshtein() and soundex() functions, plus functional indexes to query against indexed soundex first and then apply slower Levenshtein. The same tricks should also work against SQLite using the datasette-jellyfish plugin.
Cross-database queries in SQLite (and weeknotes)
I released Datasette 0.55 and sqlite-utils 3.6 this week with a common theme across both releases: supporting cross-database joins.
[... 720 words]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.
[... 786 words]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.
[... 690 words]Video introduction to Datasette and sqlite-utils
I put together a 17 minute video introduction to Datasette and sqlite-utils for FOSDEM 2021, showing how you can use Datasette to explore data, and demonstrating using the sqlite-utils command-line tool to convert a CSV file into a SQLite database, and then publish it using datasette publish. Here’s the video, plus annotated screen captures with further links and commentary.
Weeknotes: Mostly messing around with map tiles
Most of what I worked on this week was covered in Serving map tiles from SQLite with MBTiles and datasette-tiles. I built two new plugins: datasette-tiles for serving map tiles, and datasette-basemap which bundles map tiles for zoom levels 0-6 of OpenStreetMap. I also released download-tiles for downloading tiles and bundling them into an MBTiles database.
[... 350 words]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!
