I wouldn’t write off EV usage too quickly. The lithium batteries in EVs right now are around 160Wh/kg. The sodium batteries coming out of production lines now are about the same, but are also substantially cheaper, safer, and built out of more abundant materials.

Yes, if you compare them to top of the line lithium batteries coming out of assembly lines now, they don’t look as good, but those batteries aren’t in actual cars yet. It’s very likely that we’ll see cheap EVs running sodium batteries, and they’ll often be good enough. We need more charge stations more than we need better batteries (as far as EVs go).

If he’s trying to flip elections, he needs to at least pretend it’s being operated in good faith.

Their stock price will tank. They have a $3B market cap because they’re selling shovels in a gold rush. Once the gold rush is over, that valuation will go back to where they were three years ago. Probably lower, because the stock market tends to overcorrect on these things.

Companies base their capital on their stock price, and a drop like that can kill companies. Doesn’t mean for sure that Nvidia will die, but they could.

Nvidea. Their share price would be a fraction of what it is without AI. Just like the last two cryptocurrency bubbles, they went all in and then acted surprised when they popped.

At the same time, they’ve lost a lot of goodwill with gamers, formerly their core audience. With the AAA industry pulling back, games might not be pushing the limits of GPU tech anymore. Microsoft still has their old core products, but Nvidia may return to it to find a wasteland.

Careless logging is the one.

At the time Facebook was invented, plaintext passwords had been a joke for years.

Lol

They want AGI, which would match or exceed human intelligence. Current methods seem to be hitting a wall. It takes exponentially more inputs and more power to see the same level of improvement seen in past years. They’ve already eaten all the content they can, and they’re starting to talk about using entire nuclear reactors just to power it all. Even the more modest promises, like pictures of people with the correct number of fingers, seem out of reach.

Investors are starting to notice that these promises aren’t going to happen. Nvidia’s stock price is probably going to be the bellwether.

I think the best way forward would be a single board computer that can do an open source equivalent to chromecasting. Plug that in and leave your TV unconnected to the network.

You can’t do chromecast directly, because Google holds encryption keys for it. Unfortunately, this means casting apps need to be modified to support it.

There’s a few projects like this:

• https://fcast.org/

Short of it is that John Deere is preventing farmers from repairing their own tractors. How much it threatens the food supply, I’m not sure, but there is an obvious connection.

OK. How do you reconcile that with “Hashing passwords isn’t even the best practice at this point”? Key derivation functions are certainly the recommended approach these days. If they are hashes, then your earlier post is wrong, and if they aren’t hashes, then your next post was wrong.

It matters for bcrypt/scrypt. They have a 72 byte limit. Not characters, bytes.

That said, I also think it doesn’t matter much. Reasonable length passphrases that could be covered by the old Latin-1 charset can easily fit in that. If you’re talking about KJC languages, then each character is actually a whole word, and you’re packing a lot of entropy into one character. 72 bytes is already beyond what’s needed for security; it’s diminishing returns at that point.

Sarah Palin had her Yahoo mail account hacked because of those “security” questions. In 2008. We should be well past the time where they are a thing.

Some implementers reuse the same salt for all passwords. It’s not the worst thing ever, but it does make it substantially easier to crack than if everything has its own salt.

Sorta. Not really.

Key derivation algorithms are still hashes in most practical ways. Though they’re derived directly from block ciphers in most cases, so you could also say they’re encrypted. Even though people say to hash passwords, not encrypt them.

I find the whole terminology here to be unenlightening. It obscures more than it understands.

Rules here are 64 as a reasonable maximum. A lot of programmers don’t realize that bcrypt and scrypt max at 72 bytes (which may or may not be the same as 72 characters). You can get around it by prehashing, but meh. This is long enough even for a reasonable passphrase scheme.

NIST generally knows what they’re doing. Want to overwrite a hard drive securely? NIST 800-88 has you covered. Need a competition for a new block cipher? NIST ran that and AES came out of it. Same for a new hash with SHA3.

They used to have a “cache” link on search results. It occasionally came in handy when the original site was down or changed their link or something.

I have a little pet theory I’ve been stewing about when it comes to penny wise/pound foolish decisions from business owners of all types. From landlords, to local cafes, and all the way up to Fortune 500 CEOs. It comes down to bad accounting.

I’ve taken to setting aside money into buckets. There’s a bucket that handles some filter replacements for our home furnace (it’s a 5 inch thick HEPA filter, so it’s bit pricey) and under sink RO system, for example. When it comes time to buy one, I just pull from that bucket. It doesn’t feel like I’m losing anything off my usual budget for the month. The money is just there, and it feels nice to be able to pay without worry. It almost feels like a reward for good planning.

Companies do this, as well. In fact, I helped setup a similar system at my local community makerspace (which runs as a 501(c)3). We pay into buckets for things like insurance every month, and then we pay it when the bill comes due each year. Again, it doesn’t feel like we’re stressed for anything.

Not all companies do this, or if they do, they don’t do it for everything. If you’re not setting aside a little bucket for something that you know will come up, then it has to be paid out of your general funds. That’s money you wanted to use for something more fun than furnace filters or insurance or a software package that can process navigation data automatically.

So when you see billionaires or landlords complain about something important being too expensive, it might be because they aren’t tracking their accounting buckets properly. If this keeps happening, that’s a good indication that they are anything but a glorious Captain of Industry.

90% of corporations aren’t transcribing positioning data by hand every five minutes to figure out the sub’s position.
