Bullets are a bad example because they have multiple properties which makes them much harder to localise than many other sounds. I'm pretty sure most people can localise a vehicle emitting broadband noise (engine or white reversing sou

> They have to be loud enough to be heard through hearing protection. It's kind of a nit-pick, but this is not really true. Very approximately, you will perceive a sound if it is above your threshold of hearing, and also not masked

looking around a bit, it's used as an example in the documentation: https://github.com/haiku/haiku/blob/7d07c4bc739dbf90159a5c02... This is actually a great reason to keep it around; it's as simple

Yeah, it's certainly doable, just a bit tricky because the spoil-board is not attached to the base, and is replaced nearly every time. It also needs at least one extra tool set-up. If I needed a lot of double-sided boards it would be w

You're comparing a hub dynamo with cheap low-capacity rechargeable lights. Rechargeable lights from the usual suspects are generally not good, they are expensive for what they are, have low capacity, and don't have swappable stand

The simple contextlib.contextmanager example doesn't really sell the benefits. The main one is that it makes error handling and clean-up simpler, because you can just wrap the yield with a normal try/catch/finally, whereas to

A spare battery in your saddle-pack solves most of those problems. If you're worried about being without light, a (typical) dynamo system is more complicated and exposed than a battery system, so will be more prone to failure.

I get why people like them, but they make way less sense when you work out the capacity of an equivalent weight (not to mention cost) of lithium cells. It's easy to get to about 90Wh, which will run a dynamo-powered light for 30 hours

I don't see why it should be so binary. I said it "mostly" just works because there are no packaging systems which do exactly what you want 100% of the time. I've had plenty of problems with node, for example. You mentio

Yeah, I thought about that too, but if you want to process more than 255 values this might not be valid, depending on the implementation of count_if.

Just to correct my own comment: > with an uint8_t local variable and size_t return value, an earlier optimisation removes the cast to uint8_t, because it only has an effect when undefined behaviour has been triggered In this case, there

I've had a look at what's going on in LLVM, and we're both a bit wrong :) This optimisation is applied by AggressiveInstCombinePass, after the function has been completely inlined. In cases where it is applied, the i64 result

I'm not sure how "it can go the other way around too" -- in that case (assigning to a uint8_t local variable), it seems like that particular optimisation is just not being applied. Interestingly, if the local variable is &quo

Oh right, I didn't see it in a couple of passes (and searching for cast); for anyone else looking it's in the 3rd footnote. Thanks.

another solution is to just cast the result to an uint8_t; with this, clang 19.1.0 gives the same assembly: https://gcc.godbolt.org/z/E5oTW5eKe

This is incoherent to me. Your complaints are about packaging, but the elixir wrapper doesn't deal with that in any way -- it just wraps UV, which you could use without elixir. What am I missing? Also, typically when people say things

OpenWrt's dnsmasq will serve PTR records corresponding to DHCP leases, so you can use reverse DNS lookups. Use something like: dig -x ip_address_here For me it would be ideal if the prometheus exporter would expose the actual DH
