You're missing the point that I didn't need to assume it.

HN doesn't have any integrity about voting in general. Look at the "about" text of https://news.ycombinator.com/user?id=pwdisswordfishc for example, and then look at the username. There is a whole family of p

On the other hand, if deepfaking becomes common enough that everyone stops trusting everything they read / see on the internet, it would be a net good against the spread of disinformation compared to today.

>You have to implement the C version manually There's no "manually" about it. There's only one way to implement it in C, ie eight booleans and eight uint8_ts as I described. Going from there to the further optimizatio

Tangentially related, there's another "unfortunate" detail of Rust that makes some structs bigger than you want them to be. Imagine a struct Foo that contains eight `Option<u8>` fields, ie each field is either `None` or

InterlockedCompareExchange is supposed to be an atomic compare-and-swap API. "Compare-and-swap" means the swap only occurs if the comparison succeeded, ie if the previous value of `*dest` was `compare`, then `xchg` is written to `

I just use a Podman container to sandbox all the "closed-source / not from my distro's repo" software. https://news.ycombinator.com/item?id=34634584 Normally this is Ubuntu / Debian, but if I had TF

To your last point, doing it without involving glibc does have the advantage that it'll also work with musl, instead of starting yet another flamewar about missing non-standard features in musl.

Right, but other than the bug, the feature does seem nice. I do use WKD, and although nobody has ever sent me PGP email, it's nice to know that ProtonMail users would find it convenient to do so.

Traffic for that /48 will be routed to your router. You're free to divvy up that /48 into /64 subnets on your LAN. Eg you can make one subnet A:B:110::/64, another A:B:110:1::/64, and so on all the way to A:B:1

What component on your router prevents a packet with destination IP 192.168.1.2 appearing on WAN from crossing over to the 192.168.1/24 LAN and reaching the device with that IP? Hint: It's the same one that also prevents IPv6 pack

There's a nice spec for this by the UAPI group: https://uapi-group.org/specifications/specs/configuration_fi... , with the most common implementation called libeconf. The tl;dr is that an application / O

It's not really an "application" thing. It's meant to be a design for libraries that implement protocols of some sort. All the library API acts on byte buffers and leaves the network socket etc stuff to the library user.

It's called sans-io in Python land, which is where I heard it first. https://sans-io.readthedocs.io/ I did it for one of my Rust projects back in 2018 https://github.com/Arnavion/k8s-openapi/c

There are lots of trees that can't be balanced, like tries.

by Arnavion 3y ago
Tree traversal uses stacks / queues unless you're dealing with a small tree such that you're sure recursion won't blow your stack, or your algorithm can work with tail calls and your language guarantees TCO.

I think it's reasonable to *request* that a bug be treated as "High Priority because it affects my $IMPORTANT_USE_CASE". Who knows, the devs might sympathize and actually prioritize it, say because they were under the impress

There are lots of xwayland-specific bits needed to handle it running under a compositor but still acting as a privileged client compared to regular Wayland clients.

You can get that info from code coverage, via `cargo llvm-cov` etc, though that would require exercising all code paths into the deps or else you might underestimate how much of the deps you need to vendor. But at least if you underestimate

What distros are there that normally dynamically link everything but statically link sudo? OpenSUSE, Debian and Ubuntu (the distros I have on hand) do not, at least.

>You use scare quotes around "freed" for a reason: the data has not actually been freed. Who said it hasn't? I would assume such a node to have been given to `std::ptr::drop_in_place`. Not doing that would be a leak until

Out-of-bounds access is not required for the pseudo-UAF we're talking about here. Deleting a node in the middle of a linked list will leave a "hole" in the backing Vec. You cannot shift the next elements down to fill the hole

The advantage of buying RAM with XMP presets is that the reseller who created the preset has tested the sticks with that overclock and binned the original chips accordingly. When you buy RAM that is only rated for the default speed (as ECC

I didn't want to have to deal with the non-uniform CCDs. Of course the two on a 7950x aren't uniform either due to silicon lottery (eg on mine the first CCD clocks 100MHz higher than the other on all-core load and 200MHz higher on
