Sounds like an ecosystem ripe for horizontally scaling cheaper hardware.
crote · 2 days ago
If I understand correctly, a big problem is that the calculation isn't embarrasingly parallel: the various chunks are not independent, so you need to do a lot of IO to get the results from step N from your neighbours to calculate step N+1.

Using more smaller nodes means your cross-node IO is going to explode. You might save money on your compute hardware, but I wouldn't be surprised if you'd end up with an even greater cost increase on the network hardware side.

It’s been terrible for years/forever. Even Xserves didn’t really meet the needs of a professional data centre. And it’s got worse as a server OS because it’s not a core focus. Don’t understand why anyone tries to bother - apart from this MLX use case or as a ProRes render farm.

iOS build runner. Good luck developing cross-platform apps without a Mac!

For #2, OWC puts a screw hole above their dock's thunderbolt ports so that you can attach a stabilizer around the cord

https://www.owc.com/solutions/thunderbolt-dock

It's a poor imitation of old ports that had screws on the cables, but should help reduce inadvertent port stress.

The screw only works with limited devices (ie not the Mac Studio end of the cord) but it can also be adhesive mounted.

That screw hole is just the regular locking USB-C variant, is it not?

See for example:

Yikes, I hadn’t realized this was that big of a problem. The same exact G.skill z5 64Gb ram I bought 4 years ago is well on its way to being double the price. Does this have more to do with Crucial ending consumer product lines or tariffs?
crote · 2 days ago
The end of Crucial is a symptom, not a cause. Crucial is merely Micron's factory brand. Nothing is stopping OEMs like G.Skill or Kingston from buying DRAM chips from Micron and putting them on consumer RAM sticks.

Well, that's the theory at least. In practice it's more accurate to say that Micron had cut down their consumer allocation that not even their factory brand can get enough chips to survive.

> Yes, but doesn't IPv6 also increase the "maximum safe UDP packet size" from 512 bytes to 1280?

Sure would be nice if people used IPv6. Even if you're actually sending data over IPv6, that doesn't mean the DNS lookups are going over IPv6. Infrastructure like that lags.

> This has been a flagged issue in DNSSEC since it was originally considered. This was a massive oversight on their part and was only added because DNSSEC originally made it quite easy to probe entire DNS trees and expose obscured RRs.

... probably because the people who originally designed DNSSEC (and DNS) couldn't believe that people would be crazy enough to try to keep their DNS records secret (or run split address spaces, for that matter). But anyway, whatever the reason, the replies are big and that has to be dealt with.

> Fair enough but are network clients actually meant to use DNSSEC?

You should be validating as close to the point of use as possible.

> Isn't this just an issue for authoritative and recursive DNSSEC resolvers to and down the roots?

If by "resolvers" you mean "local resolution-only servers", then that's common, but arguably bad, practice.

Anyway, using TCP also neuters DNS as a DoS amplifier, at least if you can make it universal enough to avoid downgrade attacks.

I wonder if it's time to just retire this mechanism. In 2025 you'd have to be crazy to not use encryption with an internet-facing host, which in practice usually means TLS, which means your hostname is already logged in Certificate Transparency logs and trivially enumerated.

What's the bump in 2017? Did a iOS update start auto-correcting a bare "-" to "—" or something?

A lot of the proposals don't involve you sending your drivers license or "other information" to anyone. The site in question asks you to verify with a trusted third party (usually a government entity), and that trusted third party only provides then with the end result of the validation.

> which is what Google etc have been trying to do for years but this would just completely fast track that.

Excuse me? They have done that for years. There's nothing to "fast track" here. Big Tech already implemented surveillance.

How many of those proposals do not have a government-mandated app as a spider in the middle of the web, which is aware of all the apps and websites you try to visit which ask for validation?

> None of them are part of the Age Verification discussion because kids are not the actual point of Age Verification.

The EU age verification solution says implementations SHOULD implement[1] their ZKP protocol[2]. Not linking it to the user is stated as an explicit goal:

Unlinkability: The goal of the solution is to prevent user profiling and tracking by avoiding linkable transactions. Initially, the solution will rely on batch issuance to protect users from colluding RPs. Zero-Knowledge Proof (ZKP) mechanisms will be considered to offer protection. More details are provided in Section 7.

If privacy is an explicit goal, why isn't it a MUST? Why even bother with the initial batch issuance phase? And what's stopping them from silently adopting a batch size of 1?

Maybe there's a difference in frequency of usage, but we also say things like "he's not wrong" pretty often in English.
crote · 3 days ago
I reckon a decept part of that is due to American English vs. British English.

A great example of this is the Korean War, where a British brigadier in an extremely difficult situation told an American general "Things are a bit sticky, sir" - who interpreted it as "Could be better, but we're holding the line". The misunderstanding resulted in 500 dead and captured.

I suspect that people not really paying for certain things has had an impact. Remember when there were a lot of high quality, paid keyboards for Android?

I doubt those were particularly profitable, but there was a lot of innovation back then.

Why pay for a keyboard app when the default keyboard is already good enough?

Moreover, why risk installing a 3rd-party keyboard app when the App Store is filled with adware and malware? All those handy flashlight and camera apps are a Trojan's Horse, why should one assume that the various keyboard apps in the App Store aren't keyloggers trying to steal my login info?

In 2025 I can do mostly error-free blind typing on the Pixel 7 keyboard, with all autocorrect and predictive spelling intentionally turned off. Why would I need innovation?
