Ansar Allah isn't even close to a majority of the population of Yemen. Yemen is majority-Sunni. Ansar Allah is a militant Zaydi revivalist movement, and what they're attempting to revive is a Zaydi caste system.

The Houthis are one side of a protracted civil war between North Yemen and South Yemen, which was until relatively recently two different countries, and the other side of that civil war is heavily backed by the Gulf States. The Houthis are

They did that just as they began the starvation siege of Taiz.

See the comment from 'dsl upthread. As for stats: https://dnssecmenot.fly.dev/ It is not surprising that European registrars have added millions of new names nobody is ever going to visit, all of them signed by default

HN is curated by moderators and votes are just one input. All sorts of topics get downweighted all the time. Given the longevity of the AI news cycle it's not a crazy ask to suggest it get downweighted too. And it's "censor&q

By the logic you've provided here, almost everybody alive during the 19th century was severely cognitively impaired.

I totally understand where you're coming from. I'd recommend just publishing in your own words even if English isn't your best language; at this point, in 2026, it will read as charming and genuine, not slapdash. A big proble

There's so much good content in here, it's a shame you sandblasted your writeup with AI. "To the verifier, it is a number with a biography" is where I veered off the road and into a culvert.

Which of the criticisms in that article don't stand? What's changed? Adoption of DNSSEC has barely budged since I wrote it.

Doesn't this imply that the two functions have different semantics for capturing the environment?

Humanity hates it among other reasons because it's very probably false.

This comment doesn't actually say anything. I get that you're unhappy with the comment that I wrote? But that's all I get from it. The one specific claim you make here, that height has heritabilities measured at around 10%, i

by tptacek 1mo ago
This isn't true; 80s and 90s-vintage twin studies put it around 80%, but those numbers have been slashed; even hereditarians don't stand by them anymore. Molecular genetics results (contested by hereditarians, in fairness) situate

You don't seem to be sharing any of the modern rebuttals. I think it's telling that the old criticisms still basically stand.

... but then, as they point out, you have to trust DNSSEC, and that's pretty fraught --- probably more fraught than trusting a CA.

It's all an elaborate scheme by the ISRG: compete all the commercial CAs out of existence, and then charge A MILLION DOLLARS for a certificate renewal. I've seen this movie before.

by tptacek 1mo ago
There's several reasons why this might not be the case, including that our premise is simple heritability and not genetic determinism, which is a different concept. I get where you're coming from now though.

It really seems like this is a program where the exclusivity would cut literally in the opposite direction, against the startups.

I don't think trading resilience for POSIX compliance is a good call, and I don't think "strong random numbers" is at all the right way to think about this problem.

If you're an enterprise buyer I'm confident most pre-launch YC startups would be more than happy to talk to you about a pilot.

What's the "old boy network" thing here? This looks like a sales outreach event. It's connecting enterprise startups that want to do pilots with enterprises that will consider pilots.

I don't grant the premise that per-transaction urandom reads are likely a meaningful expense to begin with but on modern Linux getrandom is a vDSO anyways. Even before the vDSO, getrandom was fast. The application domain where this ten

Just because smart people tend to have fewer children (because, for instance, they delay it due to schooling and career demands) doesn't mean genes for intelligence are necessarily being selected against.

This is CopyFail. You just provided CopyFail as evidence in favor of userspace random number generators.

There are genetic traits correlated with virtually anything, including things that can't possibly be mechanistically linked to biology, so those correlations are saying less than you'd hope they would.

In what manner are you suggesting demography would be at issue here?

by tptacek 1mo ago
Forget whether you "roll your own" or not, userspace RNGs are a bad idea. The advice to rely on getrandom or urandom is as much about the superior security properties of a kernel RNG as they are about whether you'll fuck up A

Yep, Chicago is named for ramps. They're delicious and you can only get them for like 3-4 weeks in the spring.

That's the claim. It's true to the extent that the stuff in the middle of the store tends to be engineered for hyperpalatability by jacking up sugars/carbs and fats. But it's not true in the sense that ultra-processing f
