Stop crawling my HTML – use the API
One of the (many) depressing things about the "AI" future in which we're living, is that it exposes just how many people are willing to outsource their critical thinking.

The Evolution of Caching Libraries in Go
For the last few years, I've been developing caching library, and today I'd like to talk about the evolution of caches in Go and where we stand today. Especially since Go 1.24 was officially supposed to focus on caching improvements, but I haven't heard much news about them - time to fix that .

What Killed Innovation?
I entered the data visualization field in 2012, when D3.js had just come out and interactive graphics were going through a digital Renaissance. By the time I was fully steeped in the field in 2016, it felt like a new, experimental project was coming out every week—each one pushing the boundaries of how we think about…
