GitHub has stopped showing me line numbers past 60 this week. Take from that what you will about their investment priorities.
I'm not really bothered by the new iOS Liquid Glass gimmick, but what does really bother me is how half the app icons now appear to be blurry because of the shine on top edges.

So in #Rust tracing, the code handling Span::follows_from only has access to the origin Span data if the origin span isn't closed yet. That kind of defeats the point, because you'd use it for a follow-up operation that happens later, so the origin span is almost gone by definition. Or am I missing something?

The implementations are the same, naive brute force, std HashMap, pre-allocated HashMap, and as a bonus, pre-allocated AHashMap.

Unsurprisingly, same results.

Someone explain to me why there was a five minute period yesterday during which my personal website served 65k requests, 300 per second.

I do have a suspicion what's happening there.

Seeing how some folks have turned to proof-of-work methods to ward off LLM scrapers from taking down their websites, I'm dismayed that the solution is wasting more energy.

Maybe we should just make our own internet, and make it invite-only to keep out the bots.

When you see this prompt, the key is already waiting for a touch, you don't actually need to click anything.

@technomancy I've been thinking about your search engine, and what I would index if I built my own. I was thinking that indexing from the browser would be neat, and that reminded me of https://github.com/WorldBrain/Memex
