OkayPhysicist··on Evidence of a spying operation by ICE against left-wing social movements
Smart people know that "the law" has little to do with morality, and vastly more to do with power. When evil people are in power, they make evil laws, and when you have evil laws, it is immoral to follow them. Following the law is never moral in it's own right; Legality, even in the best of times, only strives to shadow morality.

I've never met someone who wouldn't prefer to change the law rather than be forced to violate them. But only cowards and the intellectually incapable think that supporting the enforcement of an unjust law while campaigning for it's fix is someone a morally superior stance.

And to answer why America? Because if we can't do it, nobody can. What kind of yellow-bellied, unpatriotic attitude can you have to think "oh, let's just let some better country solve the problems we've created in the world through prolonged geopolitical control over the 20th century". Fuck that. If America is great enough to conquer the world, it should be great enough to solve the side effects that come with it.

If you want to ignore legality, then you need to keep a rifle for every man, woman, and child in your home strong enough to shoulder one, and enough black-tips to ensure the cops bring a chaplain along for the raid.
OkayPhysicist··on I don't understand quantum physics (2018)
The photon travels a path, with a probability distribution that results in behavior that is identical to a wave, complete with interference. That's wave like.
OkayPhysicist··on I don't understand quantum physics (2018)
> There is no interference pattern from a single photon as it hits the registration device at a particular place. But collect a big enough sequence of single photon measurements and it emerges.

The same could be said of the entirely unsurprising many-photon case. The individual photons aren't demonstrating the interference pattern, just the "big enough sequence of single photon measurements". Again, that's not the interesting part of the double slit experiment. We're perfectly used to the concept of a collection of many interacting particles having wave-like properties.

The double slit experiment has non-interacting photons demonstrating wave-like properties.

OkayPhysicist··on I don't understand quantum physics (2018)
The whole point of the double slit experiment is that you get the interference patterns you'd expect from double slits, even when there is no more than one photon in the chamber at a time. One photon enters, one photon hits the detector, it's probability distribution suggests it's being interfered with.

The one-two punch of the photoelectric effect and the double slit experiment (the classic first two labs of QM) force you to accept that photons behave both like waves, and like particles.

Oh yeah, don't get me wrong "bargain-bin videogame" is a wild step up from "accidental amorphous horrors that defy description". It just jumped out to me as looking unusually bad compared to the other samples they provided. The stained glass deer, for example, was awesome.
OkayPhysicist··on Genie 4
That entire clip looks like it's straight out of a complete bargain-bin videogame. The weird smoothness of the ride, the pivot in mid air, the wings apparently don't have collision with the poles they fly past.

Definitely wouldn't have been one of my picks to show off my fancy new model.

OkayPhysicist··on Canadians are running out of time to oppose Bill C-22
Specifically, non-violent protest works by demonstrating your ability to organize large groups of people in defiance of obstacles put in your way, very much including the law. It carries with it the implied threat that some non-trivial subset of that group would take up arms if asked.

Legal, peaceful protests really only demonstrate that your opinion has some level of popularity. Which can be useful for winning over the merely apathetic, but it does nothing against the outright opposed.

Sure, but the probability of getting "4" as opposed to some number that might as as well be equivalent to latter as far as a causal reader is concerned is insanely small.
OkayPhysicist··on Dungeon generation in the Gnomish mines of NetHack
I think pass two is intended to introduce additional regions of concavity (mostly by replacing straight lines), which in effect introduces a bunch of inflection points, helping creating the organic "spiny" feel, as opposed to a "bubbly" feel. Without it, the resulting caves look a bit more like if you spilled liquid on a waxy surface, and less like thorns.

If you go into the javascript and replace "for(let p=0;p<3;p++)" with "for(let p=1;p<3;p++)", and then re-execute the block in the console, you can generate run through a bunch of generations without step 2

OkayPhysicist··on The Other Epidemic: Trying to get off benzodiazepines
If he's the GABA Labs guy, then I'm pretty sure the pitch was basically designer GHB. Which really is a fantastic substitute for alcohol. Very similar intoxication effects, with far fewer downsides. My buddy took that approach to still be able to enjoy social drinking despite gastrointestinal issues preventing the consumption of alcohol. No hangovers, either.

GHB gets a bad rep because it's extremely potent (imagine the same intoxication level as a shot of liquor from 1/3ml of GHB), so it gets used to drug people surreptitiously, and most people aren't good at controlling dosages of liquids like that. Sold pre-diluted, it really wouldn't be much different safety-wise than alcohol.

OkayPhysicist··on Ofcom concedes defeat in 4chan case
They did make peace with the US. It was a whole thing, papers were signed, agreements were made, they pinky-promised to not make nukes, everyone walked away happy. Except the Israelis, who don't like their regional power status being challenged, and apparently Trump, who... didn't like that the Iranians gave up on their nuclear armament program?

Either way, the US and Iran were at peace right up until we decided to pull out of our disarmament treaty with them. And then executed a decapitation strike against them.

OkayPhysicist··on What shall I teach my son?
The one-two punch of Goodhart's law and the McNamara fallacy bites hard here, though. We only measure things we can easily quantify, and then we optimize around those measurements, destroying their efficacy as second-order indicators of the things we couldn't figure out how to measure.

For example is the purpose of educating children about history A) to give them a systemic, if somewhat cursory, understanding of the evolution of society, in order allow them to contextualize the present? or B) ensure they know a list of a hundred or so people and events that happened?

It is much easier to quantify the latter.

OkayPhysicist··on What shall I teach my son?
As long as "being the least practiced in recorded history" is compatible with "doing well", then sure.
OkayPhysicist··on ICE Planning $100M 'Nightmare' Domestic Spy Program
If they're committing domestic terrorism, we have real cops for that. The FBI, local authorities, etc. ICE has an intrinsically non-violent job. We don't give DMV employees guns and a license to kill just because people ocassionally get pissed at them.

It is not a capital offense to interfere with the duties of law enforcement officer in the united states. It's a jailable offense worth up to about a year in prison unless you use a weapon. So "they were in the way" is abso-fucking-lutely not a reason to murder someone.

At no point in time did Alex Pretti nor Renee Good represent any direct danger to the ICE agents who murdered them. ICE agents killed Americans, in cold blood, because they knew they could get away with it. If I have to choose between a bunch of people quietly minding their own business who happen to be missing some paperwork, and a gang of blood thirsty hicks galavanting around the country brutalizing people, I'm going to pick the peaceful ones every time.

Alas, I've spent to much time typing out reasoned responses to a Fascist.

OkayPhysicist··on Passkeys are not a trap
“Once I set up a passkey I can’t log in from another device”

This literally happened to my grandfather yesterday (well, I found out about yesterday, anyway). Dude just casually mentions that he can only log into his webmail on his iPad, and I immediately knew what was up.

"so don’t. Use bitwarden or 1Password or lastpass or whatever you want to store your passkeys." -- All fine and dandy until they decide to start using that attestation feature that they 'pinky promise' they won't use for nefarious purposes.

Passkeys are literally evil, and exist exclusively because 1) companies are evil, and want nothing short of complete and utter domination of their users' lives and 2) one CEO is embarrassed that he was too stupid to realize that "my password manager isn't autofilling" means "I'm on the wrong website".

OkayPhysicist··on Passkeys are not a trap
The problem with "sites must allow you to have multiple passkeys" bullshit is that sites aggressively push you towards making that first passkey, but then hide the process for adding additional ones 6 layers deep in settings such that a typical user will never see it.

I literaly just had to unfuck my grandfathers webmail because of this garbage. "oh, I can only log into my email on my ipad now" and I immediately knew the shadowy cabal of evil over at the FIDO Alliance were to blame.

It is up to us technical users to make sure the other 90% of society don't fall for this shit. Tell them it's the mark of the beast, tell them that it's fascists seizing control of your identity, tell them whatever will make them run for the damn hills anytime they see "alternative ways to sign in".

OkayPhysicist··on Passkeys are not a trap
There is plenty adequate reason to believe that they are authoritarian assholes hellbent on stripping users of control, though. Scroll up a bit and read about the KeypassXC incident, and tell me that is the stance of an organization with user empowerment as an even distant value.

The fact that the attestation field exists at all is damning proof that they made overt plans to move in that direction. Passkeys are the mark of the beast, friends don't let friends use Passkeys, etc., etc.

OkayPhysicist··on ICE Planning $100M 'Nightmare' Domestic Spy Program
Being responsible for protecting politicians from violent lunatics is an intrinsically violent job, thus they need to be armed.

Being responsible for telling otherwise law-abiding illegal immigrants that they need to leave is not a violent job, thus they don't need to be armed.

You don't need to murder someone to remove a heckler, especially one that you have zero jurisdiction over.

OkayPhysicist··on ICE Planning $100M 'Nightmare' Domestic Spy Program
Well, a law enforcement agency that has no need to be armed at all has shot and killed at least 2 Americans, which in my book is completely and utterly unacceptable. If you asked me what the acceptable life toll was for keeping non-violent (I make that indication, because despite all the "dangerous immigrants" talk from ICE, violent acts are not under their jurisdiction. If someone commits a real crime, it becomes real law enforcement's problem. ICE, definitionally, is only needed for otherwise law-abiding non-citizens) illegal immigrants out of the United States, I'd confidently say zero.

As I mentioned in my other comment, California is far from just tech companies. You could wipe out the entire information sector and California would still be the most prosperous state in the US. California is practically the only US state to have a fully diversified economy.
OkayPhysicist··on Tesla's Robotaxis Blow Through School Zones, NHTSA Petition Alleges
Generally, there are 2 forces at play dictating how fast people will go on a given road. The probability of getting caught speeding is one, the other is the perceived safety of going fast. The issue most American roads have is that they are built extremely wide, with even more open space on either side of the road, so people are comfortable gunning it. Speed limits only matter insomuch as they adjust the perceived probability of being pulled over.

Our highways also train you that speed limit are complete bullshit. On an 8 lane, divided highway, with nothing but empty field or protective barriers on either side, 60 mph is comically low. That's how you end up with absurdities like it often being unavoidably illegal to drive on 680 in the Bay Area: either you're speeding, or you're obstructing traffic, both of which carry a fine.

IMO, the correct answer is to raise the speed limit of surface streets that already double as psuedo-highways (looking at you, San Jose), strictly enforce speed limits on surface streets, and then completely eliminate speed limits on the freeways.

OkayPhysicist··on Do dentists know what they're doing?
.That's not fair to assume. Different people have wildly different poracity in their enamel. You can be a health nut who brushes obsessively, forgoes all soda, and still gets cavities, or numbskull who does the bare minimum and is never punished. That's not to say oral hygiene isn't important, since for everyone in between you can improve your outcomes by taking better care of your teeth, but don't make the mistake of assuming that someone with shit teeth doesn't even try to take care of them
OkayPhysicist··on Why do LLM pelicans look like this?
SVGs are mostly used for icons and polygonal images, because that's what they're good at. The entire point of using vector graphics over raster is to take advantage of the fact that for low-poly objects, SVGs are much smaller. Icony-ness is definitely implied by the specification of format here.

OkayPhysicist··on Redesigning source control at Anthropic
IMO, modules vs monorepo doesn't quite address the problem. Historically, we human developers have been mostly concerned with the size of the project (i.e., the size of each commit) and the difficulties around merging work, especially with the ego side of it (why should I have to spend time changing my code to be compatible with Phil's changes?)

An agent swarm has a very different set of problems. There can be a lot more agents making changes in parallel than you'd see in all but the biggest megacorps, and the pace of those changes can be ridiculously high. The rapid pace simultaneously balloons the total repo size (because of history), and the frequency of collisions. A modifies file 1, B modifies file 1, A commits changes, B runs into conflict. Or worse, C modifies file 1 after A commits their changes and beats B to commit, resulting in B growing staler and staler as they race to get their branch merged.

This sensation of warmth while being in a nominally cold room can also be created with microwaves. A couple of such systems were designed when microwaves were the new hotness. Turns out it might cause cataracts, though.

That's trivially solved with a reflective housing, which nearly all sodium lamps I've ever seen had.

When it comes to California, it's complicated. We have a looooong history of playing fast and loose with federal supremacy, and you can bet the defendants would be fighting tooth and nail to keep any court case in California. Which would be pretty defensible, since it would presumably be a California-based company hiring California-based workers.

In particular for the noncompete ban, I believe that trying to enforce a noncompete-adjacent action like this would open you up to being sued by the employees who would have been hired, and the hiring company, in California court.

OkayPhysicist··on Character.ai has initiated voluntary Chapter 11 bankruptcy
Yes, I have lived outside of California. It mostly made me more appreciative of this state, with the notably exceptions of last call and gun laws.

Noncompete "agreements" are evil and run counter to every redeeming quality that a free market economy has. If your state allows them, they are in favor of indentured servitude, plain and simple. In contrast, California stands as a beacon for those who refuse such chains. We don't just ban noncompetes in California, we actively liberate those who move here from their out-of-state noncompetes.

And contrary to what you'll read on here, California is not just tech. We've got a massive agriculture industry (more than 50% of the country's produce), several of the best universities in the world, the entire entertainment industry (to such a degree that we're killing everyone's accents), one of the top financial sectors, and the largest manufacturing industry in the country. Hell, our restaurants are better than anywhere else in the country: I can walk down the street walk past multiple restaurants that would be the best in the entire state in most of the rest of the country, to a point that I take it for granted until I walk into a random restaurant in the heartland somewhere and expect it to be good.

We treat our companies well and our residents better. Hell, we even treat our non-residents better than any other state, given that our taxes subsidize the existence of the parasitic 41.

When the worst thing about your state is a housing shortage due to everyone wanting to be there, that's glowing praise.
