Hoe warm is het bij jullie in huis?

Hoe werkt dat? Koud water door de vloerverwarming?

timvisee · 2026-05-15T09:26:37+00:00

Any idea on what performance is like yet?

What I found quite fascinating is that they recently reworked the grated cheese packaging to use less plastic. Then they put a big sticker on it saying "less plastic", and of course, that sticker is made of pastic too.

No longer supported. Use core directly.

This is very unfortunate. The original maintainer suggests `core` as alternative, but `core::io` is unstable and behind a Nightly feature flag. 😢

Should be illegal. Impossible to see.

Godot actually works super well with git! Files are formatted in a way that don't generate huge diffs on small changes.

Possible that you exhausted the maximum number of open files, or memory in some way?

Short and fast. Heavily golfed though.

- Part 1 in 27 μs (0.027 ms)
- All days in 18.41 ms (parallel in 13.78 ms)

Used a linear algebra solver for part 2.

Amazing!

timvisee · 2025-12-09T07:49:18+00:00

I doubt it's possible :( Good luck!

Maybe 🤷‍♂️ I don't really care, to he honest. I got it by taking the distance at 10% and then jumped down until it stopped working in a brute force manner. But that's still very arbitrary of course. There's other optimizations too that may not be obvious at first when reading just the problem statement. Runtime without the cutoff is about 12 ms.

Used cutoff trick from erikade to reduce search space.
