Datasette Lite: Loading JSON data (via) I added a new feature to Datasette Lite: you can now pass it the URL to a JSON file (hosted on a CORS-compatible hosting provider such as GitHub or GitHub Gists) and it will load that file into a database table for you. It expects an array of objects, but if your file has an object as the root it will search through it looking for the first key that is an array of objects and load those instead. # 18th November 2022, 6:43 pm

Figure out how to serve an AWS Lambda function with a Function URL from a custom subdomain (via) This took me five hours and 77 issue comments to figure out, but I finally managed to serve an AWS Lambda function running Datasette on a custom subdomain with an HTTPS certificate.

Make-A-Video is a new “state-of-the-art AI system that generates videos from text” from Meta AI. It looks incredible—it really is DALL-E / Stable Diffusion for video. And it appears to have been trained on 10m video preview clips scraped from Shutterstock.

Spevktator: OSINT analysis tool for VK. This is a really cool project that came out of a recent Bellingcat hackathon. Spevktator takes 67,000 posts from five popular Russian news channels on VK (a popular Russian social media platform) and makes them available in Datasette, along with automated translations to English, post sharing metrics and sentiment analysis scores. This README includes some detailed analysis of the data, plus a link to an Observable notebook that implements custom visualizations against queries run directly against the Datasette instance. # 5th September 2022, 8:48 pm

Exploring the training data behind Stable Diffusion

Two weeks ago, the Stable Diffusion image generation model was released to the public.
