It sounds to me like the input to the algorithm is truly random, but not unbiased, and the algorithm perfectly unbiases output from the particular source they are using. The rest of the article goes into the type of flaw they're addressing, and talks about very slightly unfair dice, which you could correct, but you'd need to know exactly how unfair they are, and you're always going to be very slightly wrong and end up correcting not quite perfectly. The obvious quantum RNG is to generate polarized light and measure it perpendicular to the polarization, but you'd still need to get it perfectly perpendicular. It sounds like they've built something that doesn't rely on precise alignment to give a known distribution, which they can then use to unbias the output perfectly.

It's pretty close to being an MP3 marked as a BMP, actually. It's the result of taking a reversable transformation of the audio signal that separates out the different perceptible components and then discarding the ones that matter least, and keeping the important ones in a convenient form for accessing them. It's the first step you'd take if you wanted a computer to identify speakers or what they were saying. The only part that's image-related is making the diagram, but getting back to the data is just taking the pixel values.

I suspect that they started using spectrograms in reports at a time when getting back the data from the image would have lost too much quality to printing and scanning to hear anything as quiet as voices, but PDFs with lossless images retain all of that.

I suspect part of it is that the mitigation for DirtyFrag covers it, so everyone who blocked all the modules in question when that had only an incomplete patch probably hasn't unblocked them yet. I think this is the 4th patch for these modules, and only got a new name rather than just "there's still a way to get this code to do the wrong thing" because a different outside team found this one.

Yeah, and the person who released the information first was operating in an "if I noticed this, doing only as much as I'm doing, surely attackers would also notice" mode. Possibly some patches these days are sufficiently obvious as to their correctness and also effect that they should first become public as a set of stable releases. This was a kind of special case, as CopyFail was the combination of some code doing something strange with one user not being prepared for it, and fixed the user. If there are other users that also aren't prepared, fixing them isn't going to be subtle.

How shadows and reflections move when you're 10 milies from a mostly flat surface a thousand miles across is legitimately hard to analyze for a visual system that evolved on the ground, especially if you throw in small periodic surface orientation variations. Given how complicated it is to explain rare rainbow-related phenomena like sun dogs, it would be surprising if we'd identified and explained everything that can appear when flying above the ocean.

According to the article, they (by way of their cloud provider) had DR backups, which they were able to get restored. But getting offline backups restored takes longer than the SLAs they give their customers and loses some data that hasn't been copied offline yet, which is why they also have backups that are complete and immediately available, using the API key that the attacker -- sorry, AI -- found in a file it wasn't supposed to have access to.

I bought a used 2020 XC90 from CarMax last week. I did everything online from shipping it from Texas to Minnesota to financing the extended warranty. I walked in the door, gave them a cashier's check, and drove away within 10 minutes.

That's how it should be.

Anthropic is prepared to loosen its current terms of use, but wants to ensure its tools aren't used to spy on Americans en masse, or to develop weapons that fire with no human involvement.

The Pentagon claims that's unduly restrictive, and that there are all sorts of gray areas that would make it unworkable to operate on such terms. Pentagon officials are insisting in negotiations with Anthropic and three other big AI labs â" OpenAI, Google and xAI â" that the military be able to use their tools for "all lawful purposes."
