They did it! Aurora DSQL now supports foreign key constraints. Lack of FKs was the biggest gap between DSQL and ‘normal’ Postgres, blocking many migrations. This change makes DSQL much more viable for brownfield environments. aws-news.com/article/2026...

I finished reading Sebastian Mallaby’s The Infinity Machine today. Awesome read. A must-read to understand why the world of AI is as it is. It covers Hassabis’ background from chess prodigy to CEO of Google Deepmind, but also all the inventions that went into the LLMs we all use now. 5/5 stars.

Well this was a fun* way to spend half a vacation day - AWS suddenly blocked and 12 hours later unblocked the use of Haiku in my AWS News account. I scrambled to deploy a fallback to the native Anthropic API, and JUST as I deployed the fix, they recovered. Oh well, at least I have a fallback now.

Have you seen the new popup to go ad-free on The AWS News Feed? Probably not, because I only show it once you've been active on the site for a while (2.2% of all cases). I haven't got many members yet, but 15% of people who saw the popup (17/109) clicked maybe later, which is a very good stat!
