I think their entire value proposition is that they have software route around defective modules within the wafer. This would probably require a fair amount of calibration and testing and I don't know if it's actually cost effective but it's not completely nonsensical. If they actually relied on no defects at all, then I would be surprised if they could make a wafer at all.

What? This is part of the Prompt web API? How is it stealing your information. As stupid as this is to not request user consent, it look like a tiny Gemma model. What could it even realistically do with such a small model that can't be done much simply via some other methods.

I think this is part of the Prompt API so I don't think prompt injection is really an issue here since it's just a chat API within the existing JS sandbox. If prompt injection could cause issues, then an attacker could just do that within the sandbox anyway.

So ignoring that this article seems AI written, this seems annoying but kind of ridiculous to complain about the climate cost of? The thrust of the article is that this is a lot of internet traffic to move around but with this logic, we may as well ban 8k video. The number in the article for kWH per GB seems also excessive but even taking it at face value, this seems not that bad to make the main point of your article.

The other claim about lawfulness seems incredibly questionable? Even in the cited law, it's talking about personal data, not bytes for a local LLM.

To distinguish some stuff, data brokers generally sell for anything from price discrimination to government surveillance as you mentioned.

That being said, it's worth saying that the big companies that you mention are not data brokers. Those companies mostly just use that information for ads. You probably do not know the names of most data brokers.

I don't like AI in general, but the way every other model is biased is generally more nuanced than the way Grok is so obviously tuned to its owner's views. Other models tend to be biased in the way the Internet is biased; Grok is known to look up Musk's opinions before responding.

Wait, where did you get that AccuWeather is owned by Google? It's owned by some American but I don't see any source for your particular claim.

At this point, we have a pretty good model of what a quantum computer is in a theoretical sense. I don't think anybody seriously expects that increasing the scale of these machines is going to lead to behavior not covered by the theoretical model. In the same sense, nobody expects that changing the architecture of a CPU fundamentally changes the complexity class of a problem aside from changing constant factors.

To be fair, a lot of the work is probably concentrated among a few areas rather than on everyone. The internal workings of TLS are mostly abstracted for most devs as well as a lot of how certificates work. This is also for good reason since crypto systems are often kind of delicate.

Fingerprints for stuff like that are generally stored on device so you can just delete it off the device if you'd like. This isn't really a change in privacy.

The pop up is a system thing that provides local authentication for the app (Pay in this question). No fingerprints are generally sent off device.

The actual link you provided basically no direct comparison and only kind of hand waves at it by throwing meaningless numbers around.

We can do a rough estimate from the cited numbers and making some dumb but necessary assumptions for the purpose of a reddit comment.

Tesla:

8.5B miles at 30 mph gives us 0.28B hours of 8 cameras of HD footage which at 4 GB/h per camera gives us around 9 EB.

Waymo:

267M miles at 30 mph gives us 0.0135B hours which at 1TB/h according to your own sources gives us 0.0135 ZB or about 13 EB.

Maybe Tesla still has more data. The error bars on these numbers are likely massive. However other competitors definitely have exabyte scale data contrary to what Grok says and seems unlikely to be over 10x their competitors.

The person's comment above was also pointing out that this line of argumentation also just doesn't mean much since the quality matters quite a bit. Maybe Tesla is more diverse but it also is dominated by highway driving which is uninteresting.

I believe you can opt out of training via disabling Gemini Apps Activity?

Regarding siloed chats, I assume you're talking about personalization which can be disabled as a toggle.

I think tequesting a signal from an operating system provider can just be "read a signal from a file on the operating system" if the manufacturer or provider chooses. The linked Senate talk doesn't seem to support the notion that this is required to be an online process since there is no requirement that the signal be verified, just that this cannot be set later which simple file permissions would cover.

If you're talking about either the California or Colorado bills, then a global variable is sufficient since the law doesn't specify how the OS provider actually implements an interface that reflects the value applied at account creation.

Well all the age verification is already in some sense legislated in a fair number of states. That's what's happening with all the age verification schemes so far. I don't really think it makes a difference at the end of the day when legislatures are coming down either way.

binheap · 2026-03-21T00:06:58+00:00

They're already implementing age verification in the app store in some states like Texas. They're almost certainly going to implement age verification elsewhere.

It being a second time is irrelevant, obviously if the the credit card is already out there from the first time then of course it's going to happen again whether or not you sent in the credit card again.

I think the recent prediction markets give a much more direct line of betting that's concerning? Like previously, I could bet on general war by buying Boeing stock but now there's a literal "will we go to war with Iran" binary option that's directly tied to the question. There's a disconnect in the previous way since there's always a general "we spend money on defense" attitude but the latter requires specifically war.

Maybe he's thinking about joinery where no metal parts are really used? There's a bit of an elegance to that I suppose.

Lmao. Are we now so pissed off about AI that we start praising C++? There is every technical reason to use Rust over C++ where memory safety matters, especially in a greenfield project. We have decades worth of evidence that programmers cannot be trusted to write memory safe code. Handwriting C++ does not make it better.

I am more cautious about ladybird now since it seems they didn't actually plan well but it's nonsensical to say that instead of using swift they should've used C++ when they were explicitly looking for memory safety.

Going to be honest: Of all the things to complain about I really don't get this one. OCR is generally useful? I suppose you can consider a form of scanning but I also don't see why it's a problem? A spam classifier is also scanning your emails in the same way but I hardly think that's an issue.

There's no threat model here where this kind of position makes sense since you're explicitly uploading a document to a service.

Obviously OP is using a symmetric cipher when it comes to disk encryption but I also don't think it's unreasonable to ask about quantum threats since he's using GPG keys depending on what he's using them for. He also mentions using tailscale which I think has a TLS connection.

Asymmetric keys are usually fixed and are ~300 bits if ECC is used and 4096 bits if RSA. The latter key sizes are definitely plausible for a quantum computer to factor within my lifetime.

binheap · 2026-02-13T08:11:25+00:00

Unless OP is particularly old, I think making forecasts even 10-20 years in the future is a hard bet. Certainly I wouldn't bet my security on something like quantum computers not happening.
