Maybe this isn't what you're suggesting, but it's already possible to make an interface that prevents callers from doing math on indices in Rust — just return a struct that has a private member for the index. The caller can pass the value back at which point you can unwrap it and do index arithmetic.

And If `jj absorb` gets it wrong, you can run `jj undo`.

This is such a killer feature to me. I'm not scared to start potentially gnarly rebases anymore because I can painlessly undo.

In response, I expect the open-source community to make an optimal square packing window manager. https://en.wikipedia.org/wiki/Square_packing

Is this the Stephen Dolan of "mov is Turing Complete" fame?

Are you suggesting we move to C++++?

I've never verified this, but it feels like scp starts a new TCP connection per file. If that's the case, then scp-ing a tarred directory would be faster because you only hit the slow start once. https://www.rfc-editor.org/rfc/rfc5681#section-3.1

I don't think the OP ever returned with a conclusive answer, but I'm somewhat convinced by the commenters that it was either a low-frequency engine sound rattling the neighbor's windows or something to do with the car's rear-cross sensor.

There are yet more interesting docs in the parent directory :)

Oh no! I can run it on my phone, which is a few years old, so I figured it wouldn't lock anybody's computers up.

It's pretty CPU-heavy because it's constantly creating and updating SVG elements. I may attempt to rewrite sometime with WebGL and shaders :)

Hah, believe me, the flamethrower feature is first in line for the v2 milestone!

Oh, those are great ideas. On that note, I was also considering simulating nutrients and rewarding the roots that find them.

This is just a goofy thing I cooked up over the weekend. It's kind of like a screensaver, but with more reading and sliders. (It's not terribly efficient, so expect phone batteries to take a hit!)
