oofbey··on Ghostty 1.4
Lots of things bother me about my terminal emulators, and it's almost always in the category of "things don't work right". It's never "I wish my terminal emulator ran faster." Ghostty seems hyper focused on speed, with the negative side effect that compatibility breaks - in practice. I get that it's following all the newest standards or whatever it's doing, but in reality it always needs custom setup to work right. And for me the net effect is that it's always creating problems, not solving them.
oofbey··on Attention Is Not What You Need (2025)
You’re right I’m overly dismissive. But there are dozens of papers like this showing some more efficient alternative to attention. There is plenty of evidence pointing to this paper going nowhere.

Efficient alternatives have been coming out for 10 years now. Flash attention is the only one that has really moved the needle - because it’s not an algorithmic compromise. It’s just a smarter way to put the parentheses around the linear algebra operations.

oofbey··on Attention Is Not What You Need (2025)
They only demonstrate this idea on a laughably small toy problem. An 18M parameter model (which they call “moderate”) on an ancient dataset proves exactly nothing. Plenty of bad ideas appear to work at trivial scale.

Arguably the most important aspect of transformers is that it allowed easy training of arbitrarily large models.

oofbey··on Show HN: Steal My Bitcoin
> a fundamental misunderstanding of the economics at play

I’d say you’re the one who doesn’t understand the economics at play here. To me and I’m guessing the OP it’s quite simple. Have the exploits become common/simple enough to be worth $500 yet?

oofbey··on Evolving Threat: http2shell is an RCE in Node, Python, and more
Why are you hoping for an RCE PoC? Curiosity's sake? Or because you'd like to use it offensively? The existence/publication of such a PoC makes the world less safe.
oofbey··on Evolving Threat: http2shell is an RCE in Node, Python, and more
I’d say this is reasonably severe. For a decently large class of servers exposed to the internet there’s a pretty simple way to RCE them. The actual set of vulnerable servers isn’t nearly as big as many would like to suggest. But if you’re running a node/express server, you should really be in panic mode right now.
oofbey··on eMudhra to exit global SSL/TLS certificate business
I hear you in terms of how these kinds of mistakes typically happen. But why did the script ever produce two sets of keys? The initial root cause was somebody picked the weak key not the strong key. But what was the reason for ever producing a weak key in the first place? They say the script produced two outputs - what on earth for??
oofbey··on Eight Bits of Trust: eMudhra's CA keys cracked in milliseconds
The key generator is a FIPS certified HSM that created a strong key. They ran the key through some stupid script that zeroed out all the bytes except the last one. The point of a full FIPS audit is to check that you don’t do anything stupid with crypto like try to implement anything yourself and that you only use certified implementations. But that standard apparently doesn’t apply to CA’s. They only have to use FIPS modules to generate the keys but can do whatever idiocy they want after that. Therein lies the real problem.
oofbey··on Eight Bits of Trust: eMudhra's CA keys cracked in milliseconds
Competence is difficult to check systematically. The problem is in the auditing process. The CA auditors check a much shorter list than an application that needs FIPS compliance. They just check that the CA is using a FIPS compliant key generator, and then basic things like following a logged, standard, multi person process.

Anybody writing a system for a bank or the govt needs to have every line of code checked that it’s not doing something stupid with its crypto keys. That level of assurance would have caught this. But the process was defined too weakly.

oofbey··on How the Claude Code team does code review
No. 90% sounds like a low number. That implies something else is writing 10% of the code? People? Other models? What on earth is writing that other 10%?
oofbey··on New Apple TV 4K
TVs are getting worse not better. Except for the display. Which should be the only real concern. But the built in software is just going down hill universally.
oofbey··on Fingerprints are the new cookies
No. Almost everybody using an iPhone is on the latest release, plus or minus one while updates are rolling out. For a given iOS release and hardware type almost all of those probes are highly correlated. No way there’s 30 bits of entropy in that. I doubt there’s even 10.

Now on a desktop PC sure I believe these fingerprints are highly descriptive. And in android land they probably work okay because of the diversity of products and configurations. But iPhones resist fingerprinting just because they all give the same answers.

oofbey··on Fingerprints are the new cookies
It’s a question of entropy. If your device is unusual in detectable ways, then the fingerprint has high entropy. But on my iPhone I suspect most of the things being fingerprinted are the same. How many other people get “smug koala”?

What happened to the CIA world factbook? It was great.
oofbey··on WallHop – 12ft.io is gone, so I built a replacement
> Information should be free.

Healthcare should be free.

Food and shelter should be free.

“Should” is doing a lot of work there. Meanwhile in reality, creating and organizing information requires scarce labor which deserves compensation.

How about a morsel today? It’s topical.
oofbey··on Thorium 229 based nuclear clocks
Two teams have independently gotten a new kind of ultra precise clock working based on isomers of the thorium 229 nucleus. Currently not as accurate as atomic clocks but they have the potential to redefine the metric second.
oofbey··on Meta and Microsoft take steps to reduce employee usage of Claude AI
Absurd
oofbey··on Meta’s Muse is an adorable privacy and security dumpster fire
Probably. But also the agents are finding flaws in the security model.

Also Meta is actively encouraging users to grant them full permission, insisting with all their marketing might that it’s safe, which they know is a complete lie. Hard to blame the user when they’re being actively deceived like this. Other agent companies are more reserved and say things like “be careful” but Meta is the opposite.

oofbey··on Dust: Pretraining Transformers Without Backpropagation
This is super yawn-worthy. Instead of backprop for the exact gradient you can run forward passes a thousand times with perturbed weights and get a Monte Carlo estimate of the gradient. Not very clever. Extremely NOT useful.

But I guess the industry is littered with techniques for computing the same thing but vastly slower that some people find interesting. Homomorphic encryption. Zero knowledge proofs. Blockchain computing. Except in those cases there might be a legitimate reason to use it occasionally.

oofbey··on Powerless F1 drivers frustrated by Bahrain F1 software glitch
It’s not virtue signaling. It’s research. Pushing the limits of hybrids has downstream benefits for consumer cars, presumably.

I agree the current design is pretty dim-witted. But I think the high-level goals are sensible. It’s certainly more than just appealing to the green crowd, because that obviously is misplaced for this audience.

oofbey··on Lunar Terminator Paradox
Omg this paradox has bothered me for so long. I’m thrilled to have it finally explained.
oofbey··on When did Google get so weird?
Claude also has very arbitrary and confusing rules about what web pages it allows itself to look at, and how much of the page it can read. Did you know for example you’ll get a much deeper analysis if you download a PDF yourself and upload it to Claude instead of giving it the url?

This is a key reason why I actually like Grok for factual queries based on web grounding. It’s fast and reliable. Maybe it’s ignoring robots.txt? Dunno. But it works well.

oofbey··on In an $80 motel room, a discovery to shed light on the origins of life
Why did they work in a motel room? The article kinda implies it had something to do with Trump’s funding cuts, but unless I missed something the connection wasn’t made explicit.
oofbey··on Claude discovers a novel enzyme system with CRISPR-like repeats
In the research literature this is generally called coconut after the first paper published on the idea. It has advantages and disadvantages. I agree it’s more efficient. But the lack of observability and transferability are real downsides that block its adoption.
oofbey··on Italian parliament votes for return to nuclear energy
Right. So why don’t we see residential construction costs fall with this standardization? Because wright’s law / economies of scale don’t work when you are doing all the assembly on site.
oofbey··on Italian parliament votes for return to nuclear energy
You can’t standardize manufacturing of multi billion dollar facilities. Economies of scale just don’t work that way. Even residential housing has the same problem. There’s too much variation in on-site construction.
oofbey··on Italian parliament votes for return to nuclear energy
Wright’s law is the only way to reduce costs. It’s a generalization of Moore’s law. The more of anything you build the cheaper it gets. Most products get 10% - 20% cheaper every time total production volume doubles. The most obvious example right now is rockets - launch costs are going down exponentially because we (SpaceX mostly) are doing so much of it we are finally getting economies of scale. SMRs will too, but only if they become popular. It’s a little bit of chicken and egg, but the economics are clear. If lots of people start using SMRs they WILL get cheap. And it’s a form factor where it’s plausible lots of people will.
