After a week of meetings and calls, it was nice to dust off the ol' linear algebra and write a Delaunay triangulation and then the corresponding Voronoi cells.
This wonderful post by @ianthehenry.bsky.social was my guide through some long-forgotten math.

At last! We've missed you, @martin.kleppmann.com.
At long last, @chris.blue and I have submitted the final manuscript of Designing Data-Intensive Applications, second edition, to the publisher. There is always more that could be improved but at some point we just have to call it done. Now it goes into production; probably shipping in ~4 months.

It's pretty cool that Ink & Switch is contributing to this big ARIA programme now. We get two big things out of it: funding (obviously) but also a community of fascinating creators and problems to connect with. I'm learning all about the UK power grid this week.

The brain drain from Canada to the US appears to be reversing. Early in my career, I moved to San Francisco in search of the best opportunities. Now we're seeing folks go the other direction. Hard to see this as anything other than the end of American hegemony. Maybe it's time.

I need some help!
I’m working on a YouTube video that explores what it would take to build a web app that, if built today, could last 100 years.
It covers tech stack, dev strategies, DX, etc but I need help coming up with a demo.
Any fun ideas for a full stack app meant to live for a century??
