I was briefly very excited when I read that article, actually. But as devit points out in a sibling comment, that technique is only relevant to cases where you're adding more than 2 numbers. Multiplication initially seemed like a very

overflowing_add, like I was using above, is explicitly wrapping. I've found it very difficult to provoke rustc into emitting an ADC: the only case where it does so AFAICT is when adding u128s, which are implemented using u64s. Not sure

It's not always superior! For example, I've been working on a big integer library. Addition is a bit annoying, because you need to add 3 numbers (the prior carry bit, and the two digits you're adding) and get out a new carry

I didn't: I assumed that[1] was sufficient. But (I assume, knowing little about C++) you're right that it's actually not an infinite loop, it's signed integer underflow. Given that, I'll file a bug. [1] https:&#x2F

Yep. Here's an example I found once: https://godbolt.org/z/XQBcR9 pub fn mul1(mut a: i32, b:i32) -> i32 { let mut out = 0; while a != 0 { out += b; a-=1; } out

The Rust HashMap and HashSet implementations are generic over hasher: you can pick a faster one if you don't have to worry about getting ddos'd. Last I checked, the go-to fast hasher was fnv: https://doc.servo.org/

It's interesting to run some numbers here. Say you're a software company that's totally dedicated to removing CO2 from the atmosphere: you run a business, but that's just to fund your CO2 reduction efforts. Should you re

The incident you linked to wasn't a nuclear explosion: the rocket the nuke was sitting on exploded. FTA: "The W53 warhead landed about 100 feet (30 m) from the launch complex's entry gate; its safety features operated correct

I'm probably taking your comment far too seriously, but.... The Sun's reference frame is privileged compared to ours: it is far closer to being an inertial reference frame[0], deviating from wobble induced by Jupiter and its long

It's interesting that the headline, and the article, seem to focus on the fact that the crops were genetically modified, rather than that they were treated with roundup. This seems questionable; I would guess (although I'm no biologist), th

I'm fairly certain that wouldn't be an issue. Relativity means that any (let's say non-accelerating, to keep us within the context of special relativity) reference frame is just as good as another. In the spacecraft's reference frame, it's

It's probabilistic, but there are patterns (lines with significantly greater prime densities than others).

This is, in fact, solvable; you can use plank units, which result from setting universal constants to 1. As an example, setting the speed of light to 1 means that time can now be measured in meters. https://en.wikipedia.org/wiki/Planck_uni
