TomatoCo··on A fundamental principle of aeronautical engineering has been overturned
On a metal as soft as copper I imagine that texture'll last about 30 minutes after it's issued to the soldier.
TomatoCo··on Starship's Twelfth Flight Test
One of my favorite clips to give a sense of scale for rockets is this one. https://www.youtube.com/watch?v=70u748VALt4

I show someone and then I tell them, that's not the rocket exhaust. That's the exhaust for the engine that runs the fuel pump for the rocket.

TomatoCo··on Can someone please explain whether Cloudflare blackmailed Canonical?
This road seems to lead to the exclusion of third party app stores and/or the ability to load apps that aren't signed by Google/Apple.
TomatoCo··on New 10 GbE USB adapters are cooler, smaller, cheaper
Going by Fabien Sanglard's cheat sheet (who I trust uncritically) https://fabiensanglard.net/usbcheat/index.html it looks like 3.2 actually is a broader term than expected. Maybe there was some awful attempt at backwards compatibility? Or forwards?
TomatoCo··on NIST scientists create 'any wavelength' lasers
It reminds me of how vinyl records are fairly lossy, but they provide a superior experience in some cases because those limitations have been accounted for during the mastering process.

It's an entire pipeline from photomultiplier to recording medium to the inverse process and everything is optimized not for any particular mathematical truth but for the subjective experience.

TomatoCo··on It's OK to compare floating-points for equality
The term I've seen a lot is https://en.wikipedia.org/wiki/Unit_in_the_last_place

So I'd probably rewrite that code to first find the ulp of the larger of the abs of a and b and then assert that their difference is less than or equal to that.

Edit: Or maybe the smaller of the abs of the two, I haven't totally thought through the consequences. It might not matter, because the ulps will only differ when the numbers are significantly apart and then it doesn't matter which one you pick. Perhaps you can just always pick the first number and get its ULP.

TomatoCo··on Artemis II safely splashes down
There should be an opposite thruster for each axis. I wonder if the short bursts were due to heating limits.
TomatoCo··on Artemis II safely splashes down
The space shuttle, too, was able to communicate. I imagine the smaller the craft the smaller the angle you can "speak" out of and, below a certain size, it just doesn't work.
TomatoCo··on A cryptography engineer's perspective on quantum computing timelines
You can't do software updates securely, but it strikes me that compromising the revocation process is a good thing. Suppose you can use a key to sign a message saying "stop using this". If someone else breaks that key and falsely signs that message, what are the downsides?

You revoke a cert because you lose control of it; if someone else can falsely revoke that cert, doesn't that truthfully send the exact same signal? That you lose control of it?

TomatoCo··on I Built an Open-World Engine for the N64 [video]
This reminds me of Magicore Anomala, a side scrolling game being made for the 1985 Atari. I wish there was a way to know how people contemporary to the release of the Atari or the N64 would react to seeing these modern engines.
TomatoCo··on We broke 92% of SHA-256 – you should start to migrate from it
Wouldn't that be the play, though? Get a buttload of bitcoin, turn it into real money, then destroy bitcoin. If you found a break in bitcoin you wouldn't rely on keeping your wealth in bitcoin and then hoping nobody else discovers it.
TomatoCo··on Don't post generated/AI-edited comments. HN is for conversation between humans.
I think translation should be the only exception. It might even need to be, given how all automated translators use LLMs these days. The only alternative I see is to have people post in whatever language they're most comfortable in and then everyone else has to translate for them which just feels inefficient.

And of course, a more limited exception for posts about LLM behavior. It might be necessary for people to share prompts and outputs to discuss the topic.

TomatoCo··on Rendezvous with Rama
Conservation of angular momentum. Once everything is in it, and it's spun up, it won't stop.
TomatoCo··on UUID package coming to Go standard library
You have to generate random bytes with sufficient entropy to avoid collisions and you have to have a consistent way to serialize it to a string. There's already a standard for this, it's called UUID.
TomatoCo··on Never Bet Against x86
Now that Google and Apple have to (more-or-less) allow other app stores, I wonder if Valve is bankrolling FEX with the intent of selling games on mobile?
TomatoCo··on 7zip.com Is Serving Malware
As a power user I agree, but how do you avoid it being like the Vista UAC popups? Everyone expects software to auto update these days and it's easy enough to social engineer someone into accepting.
TomatoCo··on Recoverable and Irrecoverable Decisions
As long as the wreck doesn't go past the exit they, technically, haven't missed it yet.
TomatoCo··on Autonomous cars, drones cheerfully obey prompt injection by road sign
If you put on a reflective vest they might.
TomatoCo··on Extremophile molds are invading art museums
Does neutron radiation have the same degradation? I know there's neutron embrittlement for metals but do more plastic materials suffer the same?
TomatoCo··on Is It Time for a Nordic Nuke?
Or a fleet of TELs roaming the uninhabited regions.
TomatoCo··on Oneplus phone update introduces hardware anti-rollback
Which is why I mentioned that carriers or Google might have that as a requirement for partnering with them. iPhones are rarely stolen these days because there's no resale market for them (to the detriment of third party repairs). It behooves large market players, like Google or carriers, to create the same perception for Android phones.

Thieves don't do that research to specific models. Manufacturers don't like it if their competitors' models are easy to hawk on grey markets because that means their phones get stolen, too.

TomatoCo··on Oneplus phone update introduces hardware anti-rollback
My understanding is there was a bug that let you wipe and re-enable a phone that had been disabled due to theft. This prevents a downgrade attack. It's in OnePlus's interest to make their phones less appealing for theft, or, in their interest to comply with requirements to be disableable from carriers, Google, etc.
TomatoCo··on Oneplus phone update introduces hardware anti-rollback
Lots of CPUs that have secure enclaves have a section of memory that can be written to only once. It's generally used for cryptographic keys, serials, etcetera. It's also frequently used like this.
TomatoCo··on LLM Structured Outputs Handbook
You can't do it as part of whatever's calling it because this changes the sampler. The grammar constraints what tokens the sampler is allowed to consider, only passing tokens that are valid by the grammar.
TomatoCo··on The chess bot on Delta Air Lines will destroy you (2024) [video]
Ah, the Zap Brannigan school.
TomatoCo··on Sampling at negative temperature
I'd assume that's just an optimization? Why bother sorting the entire list if you're just gonna pick the top token, linear time versus whatever your sort time is.

Having said that, of course it's only as deterministic as the hardware itself is.

TomatoCo··on Drones that recharge directly on transmission lines
It'll definitely charge faster, if only because it's drawing less power to stay up and getting closer. The only question is, is it like 10% or 100% faster?
TomatoCo··on Microsoft May Have Created the Slowest Windows in 25 Years with Windows 11
Although there are some places you want that! WireGuard is often described as cryptographically opinionated because it doesn't even bother trying to negotiate crypto primitives which makes it immune to downgrade attacks. Though, to be fair, that also means that if its primitives ever do get broken you need to roll out an entirely new release.
TomatoCo··on Millennium Challenge: A corrupted military exercise and its legacy (2015)

TomatoCo··on A faster heart for F-Droid
For some reason I'm reading emphasis on "just any" in their statement "not hosted in just any data center". I feel like it's at a data center run by this long term contributor.
