    He’s right that current quantum computers are physics experiments, not actual computers, and that people concentrate too much on exotic threats, but he goes a bit off the rails after that.

    Current post quantum crypto work is a hedge, because no-one who might face actual physical or financial or military risks is prepared to say that there will be no device in 10-20 years time that can crack eg. an ECDH key exchange in the blink of an eye. You’ve got to start work on PQC now, because you want to be able subject it to a lot of classical cryptanalysis work because quantum-resistant is no good by itself (see also, SIKE which turned out to be trivially crackable).

    The attempt to project factorising capabilities of future quantum computers is pretty stupid because there’s too little data to work with, so the capabilities and limitations of future devices can’t usefully be guessed at yet. Personally, I’d expect them to remain physics experiments for at least another 5-10 years, but once a bunch of current issues are resolved you’ll see rapid growth in practical devices by which time it is a bit late to start casting around for replacement crypto systems.

    An entertaining bit of pushback against the various bathroom bills being pushed at the moment. Bonus points for linking it with ai training. I feel like this is an idea that’s very adaptable…

    an entire economy built on intellectual property thievery

    The historic attitude of the US to copyright is interesting (you can still see old English-language books that are labelled not for sale in the USA). In these enlightened days of course there’s a half-trillion dollar plan to shore up the LLM business, which is already a half-trillion dollar crater of debt and is still digging hard.

    and slave labor

    I always wondered how the manufacture of white goods in the US was competitive with the likes of Mexico, and it turns out that the secret ingredient is incredibly cheap prison labor, where the prisoners face significant negative consequences if they’re not prepared to work for pennies.

    Prisoners can be firefighters for a few dollars a day and risk their lives, but are denied jobs when they get out. California, that noted bleeding heart lefty bastion, refused to abolish penal servitude (ie. slavery of prisoners).

    The US health insurance industry means that huge swathes of the population may as well be indentured because cannot afford basic healthcare if they quit and changing employers risks rejection of coverage of pre-existing conditions.

    I could go on. For quite a while.

    all the downvotes confirm the ccp is here and active on the fediverse

    By all accounts, the ccp do a pretty poor job of influence operations compared to russia. Personally I suspect that the fediverse is just too small compared to twitter and bluesky and reddit, so why would anyone bother here?

    Truth is, both the US and the PRC are capitalist hellholes of differing degrees, and the current team in the White House works hard to reduce those differences. Remember, with the right wing, it is always projection and envy. They hate Iran because they want to be a fundamentalist dictatorship too. They hate china because they want uncontested power and a labor force without human rights.

    You are not obliged to carry water for them.

    The biggest issue I have is that the firmware cannot be updated (which I realize is somewhat a matter of taste regarding your threat model). Other than that, it’s the added complexity of “use this physical device” and the concern I had about recovering accounts if I lost the Yubikey.

    The solokey v2 and the nitrokey v3 (I think) have some firmware upgradability, but they’re not as capable as a yubikey (the last time I checked I couldn’t use either of them to unlock a keepassxc password vault, for example). Whilst it would be a right hassle to deal with a lost device, I generally lock my accounts with a main key and two spares that get stored safely and make a note in my password database of which accounts can use which keys so there’s little risk of locking myself out of anything, and I can get a list of sites to visit to revoke credentials from. In any case, the minor inconvenience is a good tradeoff for me, given the significant security guarantees the keys offer over other authentication mechanisms.

    But also, “added complexity” is just a thing with two factor authentication, and most of my use of U2F keys involves less effort than unlocking my phone, then unlocking my TOTP application, then searching for the account and site I’m trying to unlock, then waiting for the timer to reset because I can’t authenticate before the current code expires, etc.

    Assuming I didn’t fuck up basic math,

    Beats me! I just use off-the-shelf entropy calculators and hope they’re right. They mostly seem to agree that ~128 bits of entropy from a 10-word (70-85-ish characters) passphrase from the EFF large wordlist, or ~24 characters from uppercase/lowercase/numeric. Both might be reasonably considered overkill, if you can be sure that the thing that’s hashing the password is using a modern algorithm (which often you can’t, sadly).

    I also dislike unreasonably long passwords because more modestly-sized ones can be typed out manually when needs be, or even read over the phone in an emergency. I wouldn’t fancy doing that with 128 character passwords! You may of course never need to do those things, but I’ve needed to do both, at work and otherwise.

    Last time I tried it, ungoogled chromium had some issues with yubikeys (see https://ungoogled-software.github.io/ungoogled-chromium-wiki/faq#how-to-get-fido-u2f-security-keys-to-work-in-google-sign-in) which I don’t think have been fixed yet. That was enough to be a deal breaker for me.

    do yubikeys suck as much as it looks like they suck?

    Without knowing why you think they suck, it’s hard to say. I like having unphishable uncopyable credentials, and it irritates me that they aren’t more widely supported. On my desktop or laptop, they’re less irritating than TOTP, for example, which is neither unphishable nor uncopyable but much more widely used.

    whereas passwords that will always be copy-pasted are 128 characters

    Whilst there isn’t really such a thing as “too secure”, it is the case that things like passwords are not infinitely scaleable. Something like yescrypt produces 256-bit hashes (iirc) so there’s simply no space to squish all that extra entropy you’re providing into the output… it might not be any more secure than a password a quarter of its length (or less!).

    128 bits of entropy is already impractical to brute force, even if you ignore the fact that modern password hashes like yescrypt and argon2 are particularly challenging to attack even if your password has low entropy.

    Corporations institute barebones, born yesterday AI models that don’t know their ass from their elbow because they can’t be bothered to pay the devs to actually train them but when shit goes south they turn around and blame the devs for a bad product instead of admitting they cut corners

    Sounds like all it would take is one company to do it right, and they’d clean up. Except somehow, with all of the billions being poured into it, every product with ai sprinkled on it is worse than the non-ai-sprinkled alternatives.

    Now, maybe this is finally the sign that everyone will accept that The Market is completely fucking stupid and useless, and that literally every company involved in ai is holding it wrong.

    Or, and I know it’s a bit of a stretch here, but consider the possibility that ai just isn’t very useful except for fooling humans and maybe you can fool people into paying for it but it’s a lot harder to fool them into thinking it makes stuff better.
