How Uber is Evolving Schemaless into a Distributed SQL Database — An update to a hugely popular set of blog posts from 2016 about how Uber built a ‘schemaless’ data store on top of MySQL. Their thinking has evolved somewhat since then. Uber is now working on ‘Docstore’, a multi-model database that can scale horizontally – it still uses MySQL under the hood, though.

Firefox 86 Introduces 'Total Cookie Protection' — The goal of ‘total cookie protection’ is to confine cookies solely to the site where they were created, rather than letting tracking companies use them to track your activity across the Web. It essentially gives you a separate ‘cookie jar’ per site. This is part of a broader idea called state partitioning.

Modernizing from PostgreSQL to Serverless with Fauna — It pays to note this series of blog posts is by Fauna so there’s natural bias here, but any “why you might move from X to Y” example interests me when it comes to data, and serverless data APIs do offer a lot of benefits for certain use cases. Seeing how they remodel the data is quite neat.
