Single sign-on against GitHub using ASGI middleware
I released Datasette 0.29 last weekend, the first version of Datasette to be built on top of ASGI (discussed previously in Porting Datasette to ASGI, and Turtles all the way down).
[... 1,612 words]Porting Datasette to ASGI, and Turtles all the way down
This evening I finally closed a Datasette issue that I opened more than 13 months ago: #272: Port Datasette to ASGI. A few notes on why this is such an important step for the project.

[... 1,237 words]Exploring search relevance algorithms with SQLite
SQLite isn’t just a fast, high quality embedded database: it also incorporates a powerful full-text search engine in the form of the FTS4 and FTS5 extensions. You’ve probably used these a bunch of times already: many iOS, Android and desktop applications use SQLite under-the-hood and use it to implement their built-in search.

Changes are afoot at Zeit Now, my preferred hosting provider for the past year (see previous posts). They have announced Now 2.0, an intriguing new approach to providing auto-scaling immutable deployments. It’s built on top of lambdas, and comes with a whole host of new constraints: code needs to fit into a 5MB bundle for example (though it looks like this restriction will soon be relaxed a little—update November 19th you can now bump this up to 50MB).
