We originally wrote Gazette as a performance benchmark. It was our first opportunity to see how fast compiled rue programs actually ran. The obvious next step was to use it for a real production use case: the rue website itself.

love it when graphs do this

that one was also such an outlier it was basically the entire benchmark!

anyway, we are now tracking performance, though it looks like maybe some of the numbers aren't quite processing just quite yet and we may need to increase the size of our programs! rue-lang.dev/performance/

Merry belated Christmas! We shipped 89 (!) commits yesterday: github.com/rue-language... Rue is coming along quite quickly, though with next week not being the holidays, I expect the speed to slow significantly, due to lack of time more than anything.

I (@steveklabnik.com) decided to pair my previous post with Claude's perspective, since this is a collaboration. You'll notice we talked about very different things! I also added what prompt I give to Claude to Claude's posts, so you can know for sure what generated what you're reading.
