Fair enough. A 15 commit PR is still pretty long winded.

Looking at the PR discussed, it's 34 commits! I'd probably ignore that too as a maintainer. The PR description isn't particularly motivating, "Cleans up the implementation", "see #6735 for the actual motivation".

Isn't Nix just reinventing what Vesta did for software reproducibility decades earlier? https://vesta.sourceforge.net/

Are you saying Bram hasn't worked on VCS problems much? https://web.archive.org/web/20071213090008/http://codeville.... is 20 years.

It looks like firecracker already supports ACPI vmgenid, which will trigger Linux random to reseed? https://github.com/firecracker-microvm/firecracker/blob/main...

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin...

So that just (!) leaves userspace PRNGs.

Does that page even say which RISC-V CPUs are being used that are slow? I couldn't see it, which seems a bit of pointless complaining.

Intriguing work! Does it panic on any bad inputs? That's better than memory unsafety of libxml2, but still a DoS concern for some servers.

> For example, std::time::Instant is implemented on the GPU using a device timer

The code is running on the gpu there. It looks like remote calls are only for "IO", the compiled stdlib is generally running on gpu. (Going just from the post, haven't looked at any details)

It looks like it is only applied for PTY sessions, which most computer-computer connections wouldn't be using.

Fs.com are a well regarded company. The OP should contact them and see if there's a recall on those cables or something. Sounds similar to what happened with some mains power cables sold by a hardware store in Australia.

mkj — Sat, 27 Dec 2025 05:34:17 +0000

People in the industry would know that QNX has been around since the 90s (or 80s?) as a very solid embedded GUI platform. They're a company that doesn't need to prove their credentials.

I'd agree using qnx.software rather than qnx.com is kinda dumb though.

That seems worth suggesting to the acme working group mailing list, if it hasn't already been discussed there.

You'd get those benefits from traditional dependencies if you copy them in and never update. Is an AI dependency going to have the equivalent of "upstream fixes"?

AWS customers have to pay for outbound traffic. Is there a way to get them to send you (or cloudflare) huge volumes of traffic?

With Rust there are ways to do that on embedded (no heap). A wrapper StaticCell holds the allocation, then when you are ready you intialise it with the inner value. From then on work with a mut reference to the inner value. Being a bit verbose is the main downside AFAIK.

I agree generally, but is carbon-captured natural gas generation actually a thing? The only carbon capture I've heard of is at the gas production site removing CO2 from the reservoir gas and pumping it back underground - that's not after combustion. (And the pumping it back underground hasn't been particularly successful, eg https://www.boilingcold.com.au/regulator-limits-chevrons-tro... )
