Random reflection:
The most valuable information about a piece of code, or a patch, is not how it works. Or why it works. Or who wrote it.
The most valuable information is why it was done in that way in particular.
Did someone implement it the first way they came up with, without giving it much more thought?
Did the author know a better way, but was in a hurry so knowingly used a quick workaround?
Or is there a very subtle reason that this has to be done this way that took days to discover?

What if I have a chunk of memory with a bunch of counters that are being constantly updated by another thread, and I want to make a private copy of it (doesn't have to be consistent as a whole, only each counter needs to be internally consistent) to read at my leisure, without the other cores' writes pushing it out of my cache?
Not a real case where I found this to be a bottleneck, just wondering what are the possibilities.

If wireguard wants to be a primitive, a building block in larger solutions, that's fine, but:
- I couldn't find anywhere stating that
- Doing both routing and filtering based on AllowedIPs looks out of place. It's not suitable for any advanced usecase - you end up needing one interface per peer anyway. So it only makes sense as a way to make WG easier to use stand-alone.

Well, wireguard is not much different from GRE orIPIP in that regard, so a tunnel agnostic reachability detection daemon that adds and removes statically configured routes would've been a more universal solution. It could eg. use BFD.
Still, if wireguard is trying to be a "batteries included" type of solution, I'd expect it to have such a feature, at least in the userspace tooling part.

2026-03-28 10:01:03 UTC

Imagne wireguard but it detects if the peer is reachable and only adds routes when it is.

Unix shells tend to show the local hostname in the prompt, so that you see it at all times.
Cities, OTOH, don't have their city name written all over the streets. It's usually written next to major roads when entering the city, but once you're inside, it may be difficult to find out which city you're in.

And in general, I don't like the surface-level mockery - it seems to imply that US has to be utterly incompetent to let those things happen, which I disagree with.

AFAIK its scheduled maintenance time was in the middle of the Special Maduro Operation.
Also, the US did not exactly choose when to start a war - AFAIU they were in a rush to start it while there's still a potential for protests in Iran.
It seems they're 1 carrier short - if they had one more, they could've sent it to the Gulf to replace Ford, and be able to intervene when the protests were happening, instead of doing that 1.5 months later.

As for per-program balancing - tc-flow classifier can hash locally-originated traffic by socket uid and gid, but sadly not by pid. Also, traffic class can be set using cgroups (see tc-cgroup) but that doesn't sound very useful either.
Unless you use flatpak, I guess.

o, a zrobili osobny na "byłem, wrzuciłem awizo, ale paczka nie zmieściła mi się do auta, tylko nie idź na pocztę przed końcem dnia bo oni nie wiedzą że jej nie wziąłem"

@nprofile…rmme hmm okej, i to "W transporcie" pojawia się raz, i nie ma jakichś stanów pośrednich typu "W transporcie ale już we właściwej miejscowości" itp?
