Shield is a 10 year old device at this point. It's essentially the 2017 hw that they've refreshed a couple of times with minor changes. Wait for the actual shield next for proper support.

Yes, there is no point in grading homework or essays. This has been largely true in India and China anyway, and the US will have to move to similar model of standardized tests and in person exams. Universities are anyway proxies for IQ filtering. It is perhaps impolite to say so explicitly in the west, but people will have to confront that.

It's describing a different type of parallelism - pipeline parallelism. The network is laid out spatially on the wafer in CB's case. So weights are stationary and activations flow. A GPU is going to process the network one layer at a time. GPUs also use other types of parallelism (tensor and expert mainly in inference). Pipeline parallelism doesn't make much sense on a GPU for inference.

It's SRAM. It's the equivalent of 44 GB of CPU cache.

The reason 2D grids work well is because you can split tensor axes along whatever dim you want across PEs (batch, sequence, hidden, etc.). And your per PE code is relatively simple. It's of the type : get data from neighbor, compute my subtensor, send to neighbor. And you can implement broadcasts and reductions along any axis.

No, yubikey in the fido/webauthn form protects against phishing/TOTP snooping and replay over the web. TPMs for luks don't. See the other thread about evil maid.

That's a minor convenience to not type passphrases and a fairly high risk of you losing the backup key. Not to mention, the entirely separate problem of storing the backup key securely. It doesn't pass the xkcd "correct horse battery staple" test for me.

What does it matter if it doesn't unlock the disk? It's a different device with a logger. The purpose of the maid is to be evil and steal your pin. The maid has your real device. The only way to prevent this is by you authenticating the device before you enter anything. Look at the heads project (https://github.com/linuxboot/heads).

The maid can just swap out the laptop for a diff one.

What problem is this solving though? The post says they're doing this to avoid typing passphrases. Why would you want the private key hidden in the tpm chip of that device? How will you decrypt if the laptop goes bust or if you move the drive elsewhere?

Why is everybody (in the government) in the EU so illiterate? Do they not understand that their economies are dead and football streaming isn't going to save them.

Wait, what has North America got to do with anything? Are you trying to smuggle in Canada for preferential treatment?

>Why pay to reach many thousands of people with a widely read paper when you can pay pennies to reach dozens of people that you don't want to apply to the job anyway?

Because the requirement is good faith effort, not exhaustive search. So much of this thread is people not understanding the law. The purpose or the requirement isn't to interview 342M Americans and reject them and only then would you hire a foreign national. People wish that that were the case, but it isn't.

Ya, dude, it takes time. Are you unfamiliar with how federal litigation works? So far we have a tweet from the government. They need to put whatever they have concocted in writing and send it to MS. Then MS will file a complaint that shows injury. Or they'll negotiate a settlement even before it goes to trial. And so on. Like I said, we shall revisit in a few months once the dust settles.

Courts deal with live controversies, they do not rule on abstract things. So, if the case moves to trial, the court will rule that there is no such thing as a legal blanket ban as enacted here. As for settling, you can go back to the top of the thread where I claim that there is no successful prosecution. If you think that is a win, more power to you. I get the feeling that we have been in agreement the whole time. Make noise -> shakedown -> press release -> settle is what happens always. I count that as 'no successful prosecution', and you count that as a win.

That's preaching to the choir though. The people who need convincing aren't in silicon valley or even CA.

The purpose of the system is what it does. At the very least 2 votes on the bench are default admin votes. It's not the activists who are claiming things. You can look up overall SCOTUS approval trendlines.

The present unilateral action of banning MS from using PERM is unlawful as MS hasn't broken any laws. (PERM has its own cooldown mechanism of timeouts after layoffs. I'm not talking about those.) If the US government bars MS on any grounds of fraud, abuse, misrepresentation, etc., or if the US government tries to claim that they have the power to unilaterally ban PERM for MS, they will lose in court or settle. We can revisit this in a few months.
