For some context, just presented by Matz at RubyKaigi 2026. It’s experimental but he built it with help from Claude in about a month. Successful live demo.
It’s named after his new cat, which is named after a cat in Card Captor Sakura, which is the partner to another character named Ruby.
- rayiner 5mo ago> It’s experimental but he built it with help from Claude in about a month. We talk a lot about AI building programs from soup to nuts. But I think people overlook the more likely scenario. AI will turn 10x programmers into 100x programmers. Or in Matz’s case maybe 100x programmers into 500x programmers.
- satvikpendem 5mo agoAI is the function f(x) = x • |x|. It turns 10x into 100x, 1x into 1x, and -10x into -100x.
- networked 5mo agoSomething there, but this sounds too optimistic for x ∈ [-1, 0] and too pessimistic for x ∈ [0, 1].
- satvikpendem 5mo agoI should specify the domain to be ℤ
- DeathArrow 5mo agoIt actually helps me write better code. I am pretty lazy so I kind of don't do much refactoring unless I have to, I care mostly about happy paths and I kind of avoid treating edge cases unless I can't do it. I usually don't optimize much. But since writing code is very easy now with AI I write better code because it doesn't take me more time and effort.

- debugnik 5mo agoThe most recent cartoon Spinel in my mind is from Steven Universe, so I hadn't noticed the Spinel/Ruby (Moon) pun, that made my day.
- riffraff 5mo agooh, I thought it was about the mineral which is ruby-ish :) https://en.wikipedia.org/wiki/Spinel https://en.wikipedia.org/wiki/Spinel
- the_gastropod 5mo agoThat cat story seems more than a little suspicious given the Ruby Central drama / its relation to the founders of Spinel.coop. This project feels likely vindictively named.
