vectorjohn··on What Is the Secure Enclave?
Aren't the contents of NV memory pretty important though?

Anyway, it's just different than software. You can't sha sum your hardware to verify its what you expected.

I'm not sure, maybe an x-ray could see inside. Not unlike how binary blobs can be examined, but usually that's not considered open.

vectorjohn··on What Is the Secure Enclave?
It isn't possible to open source the hardware. If the secure enclave is really secure, it has parts that by definition cannot be examined or verified. So hardware specs can be open, but you'll never have any guarantee that's what you're getting because hardware is always a compiled blob.
vectorjohn··on Justice Department Calls Apple’s Refusal to Unlock iPhone a ‘Marketing Strategy’
This analogy is garbage. No building is being destroyed. The FBI is asking for a key to this one unit, and the fact that Apple even has the ability to make the key should be evidence that the system isn't as secure as you think.

Inside the storage unit is yet another invincible locked container, but the FBI is betting on the key being easy to guess.

vectorjohn··on Justice Department Calls Apple’s Refusal to Unlock iPhone a ‘Marketing Strategy’
Yeah, I'm with you on this. Apple really does have to help, and they're reluctant purely because they know they made a vulnerable device. Helping would make them look bad because it would bring to light that they have the ability to help.

It sounds like they could have made a device that even a firmware update couldn't break, but they didn't. I really don't see how they can refuse. Your analogy is good.

vectorjohn··on Japanese firm to open world’s first robot-run farm
Ok, so they're going to be 2% efficient at using that 20% that was gathered by PV cells. So it still seems like using 2% of all the light would be more efficient than using 2% of a fifth of the light.

I suspect that by 2% efficient, that means they use 2% of the energy of all light. Since they don't use green at all, going through the PV and then generating artificial light of the frequencies they need does seem to improve things. But probably not by so much as to make up for the 20% efficiency of PV.

vectorjohn··on Japanese firm to open world’s first robot-run farm
Sun is not free. Sun requires land. If (and I don't think we're there yet) you can get to where the sun gathered by PV can be used to grow more plants than direct sunlight, and you're in a space constrained place like Japan, it starts to make sense.

I mean, you can stack farms vertically if artificial light is economical. You can't stack sun-lit farms vertically.

vectorjohn··on Japanese firm to open world’s first robot-run farm
I don't know if that actually works in practice. Aren't photovoltaics (commercially feasible ones) like 20% efficient? Sure, its 20% of a bigger spectrum, and plants aren't perfectly efficient either, but I don't know if the math quite works as well as you make it sound.

The other benefits are awesome though. And our fusion future will make the photovoltaics issue moot anyway :)

vectorjohn··on Everyone’s offended these days
There is nothing wrong with being afraid to attack Islam. It is a legitimate scary death cult. So is Christianity, but Christianity is somewhat safer to criticize.
vectorjohn··on Olbers’ Paradox: Why Is the Sky Dark at Night? (2000)
Sure. But that really is just pedantics. It isn't a surprise to anyone to point out that the source of something that was moving away from us 13Gy ago is now further away than it was. You are essentially just giving those words the least charitable interpretation and then picking on that. It isn't wrong, its just not perfectly unambiguous.

"most is in use most of the time"

I don't know how you measured that, but Linux will use all of your memory all of the time with various caches.

vectorjohn··on Project Natick: Microsoft's Underwater Data Center
The data center generates the same amount of heat no matter what. It doesn't matter where it's generated. So unless you're arguing that we shouldn't have data centers, I don't understand your point.
vectorjohn··on Project Natick: Microsoft's Underwater Data Center
And that's if it was a closed system with no other sources or sinks of heat.
vectorjohn··on Project Natick: Microsoft's Underwater Data Center
I'm not sure what nitrogen has to do with humidity. I don't think anything. If humidity was the problem there are other ways to deal with it (the water doesn't come from nowhere, and once it's gone, you won't get any condensation anymore).

Sounds like (pressurized) nitrogen had more to do with increasing the air density for heat transfer. But I still don't know why they chose nitrogen.

vectorjohn··on San Francisco Bubble
What do people normally count in cost of living? Utilities and services are fine, and groceries are easy to find reasonably priced. Transportation is fine.

So I think as others have mentioned, rent and house prices are the things climbing sharply. I know someone paying $900 for a room in a 3 person house, in a really great part of town (Division, for locals). I've heard studios go for well over $1000, and fill up fast. But really, you don't have to look very hard to find something cheap(er). Surrounding areas (with new access to light rail that goes down town) are reasonable.

I don't think it's really as bad as some people make it out to be, but it definitely is getting more expensive in town. I mean, that's the nature of the housing market recovery :)

vectorjohn··on San Francisco Bubble
I don't see why not, they have to pay rent too.
vectorjohn··on San Francisco Bubble
Compared to Portland, $7 a beer is actually pretty expensive. Not as crazy as the mythical $15, but for a local craft beer it should be more like $5-6. But that could all just be taxes.

(and we do have $7-12 beers, they're just known to be extra fancy or aged)

Probably because Chicago is not America.

We don't do anything. We'll have to take care of them, which is where things like a basic income help. It won't happen all at once instantly, and it's not like our only option is to grind them into soylent green. Horses may get turned into food, but that's because they're horses and not people. We eat animals, so it's not very compelling to say "oh no, we ate all the horses or turned them into glue". Who cares. The point is there are horses now and there will probably continue to be horses. Many of them with a life of mostly leisure and good care instead of being worked to death. Sounds good to me.
vectorjohn··on Request For Research: Basic Income
Precisely this. Basic income is a fantastic safety net and gives a lot of freedom to people. That's its whole point (that and it's a starting point to solve the problem of increasing automation eliminating jobs, but we don't know for certain if that will happen).

Jobs that are currently mostly done by people with no other choice, and hence can pay as little as they want, will have to pay better or be part time or some other benefit if they really need to get done.

And then, if a crappy or mindless job ends up paying $30/hour, people might do it because they want the extra money, not because they need it to survive.

vectorjohn··on Request For Research: Basic Income
Hmm, I think there are actually zero or very few examples of populations given permanent welfare where something bad happened. In fact, the exact opposite. I really feel bad for the people in permanent welfare in Sweden where health care is free and standards of living are extremely high. Yeah, that's terrible.

I read a lot of that discussion on meta filter, and it was extremely unconvincing. I empathize with women who marry crappy people who expect them to stay at home and don't want to listen to their problems and want them to send birthday cards to their family. But the whole conversation was about a non issue. Basically like the argument any roommates would have about who has to do the dishes. Or who left the toilet seat up. It was complaining about personal things that they really just need to deal with themselves. And maybe they need help learning to do that, but "emotional work" isn't a thing. It isn't, it shouldn't be compensated, it doesn't exist. These aren't big societal dilemmas. Women aren't perfectly equal now but it is perfectly acceptable in most of the western world for women to get real jobs.

Or maybe it would help to hear an example (any example, you still haven't given one). What is one hard choice a woman might have to make to escape the pain of being poor? The hard choice not to have children? How is that a hard choice and how could it possibly go away in any imaginable future without the reality of biology being worked around with external wombs and robotic child care? And what, please tell me, could that have to do with a basic income?

vectorjohn··on Request For Research: Basic Income
Yeah, I'm more convinced this has nothing to do with basic income. You are just repeating over and over that basic income will make it worse but with zero proposed mechanism.

Unpaid house work isn't going to get worse if women get the (new) option of leaving situations they previously were stuck in.

The problem of unpaid "emotional work" is caused by a sexist society. More social safety net either does nothing to alleviate that problem, or it helps. It makes no sense to argue it makes things worse. Unless you provide even a shred of an argument for how it could make things worse, it sounds like you're just yelling into the void of the internet. Unless by "men are impossible to talk to about this" you really mean "men don't accept my assertions on faith".

Edit: Also, it sounds like possibly you don't know what basic income is. Or you mean something different by it. This[1] sums it up neatly in the first paragraph. I'm not trying to be insulting, it just sounds like you're talking about something different.

vectorjohn··on Request For Research: Basic Income
Hmm, that doesn't make any sense to me.

You were very vague about what this "care" work is. For child care, as in your own children, somebody has to do it. It shouldn't be assumed to be women but it makes no sense for this to be a paid thing.

If you mean something like elder care, for example, and you don't feel it's worth doing it for free, then just don't do it. I don't know why you feel (or you feel anyone else) would be expected to do this work

With a basic income, if you think elder care is important and/or something you want to do, you can afford to do it for free. Because you have a basic income. If you want more than a basic income you have to do something that people want to pay for. But you have the freedom to walk away from any job without fear of homelessness and poverty.

Your worries about permanent slavery seem to have very little to do with basic income. In fact, the main reason for basic income is to free people from the wage slavery we have now. People are stuck in barely livable wages because they don't have the time away from work to get into a better paying career.

vectorjohn··on Request For Research: Basic Income
Did you mean to reply to someone else? It doesn't sound like you disagree at all.

If there was a basic income, people who do things that currently aren't paid for, like what you mentioned, could be done and "paid for" by the basic income.

If you like the work, but just want to be paid, that should solve your problem.

If you don't like the work, don't do it. The basic income would mean that jobs that people don't like doing would have to increase what they pay until someone is willing to do it. Nobody would be forced to do work they don't like for a barely or non-livable wage.

vectorjohn··on Request For Research: Basic Income
Two months per year? To me that's worth it. I want to live as long as possible, but that is strongly based on how much I enjoy life. If the things people enjoy happen to be a little unhealthy, it may be worth it.
vectorjohn··on Barack Obama: Why we must rethink solitary confinement
Neither of those definitions disagree with me. I mean, if you read it with your apparently biblical bent, then "treating people equally" probably means the rapist should be raped and killed. But no sane society thinks that's a good idea.

"Just or appropriate" doesn't actually say anything about what should be done in a case of rape+murder. Who's to say life in prison is appropriate? I don't think it is. It's a waste. The young lady wasn't put in a hellish environment for a lifetime. And what do we as a society gain by wasting money on prisoners for exactly zero return on investment? We're basically punishing ourselves to spend that money. Better to wait until the problem is solved (i.e. we don't think they'll do it again) and let them out where they can do something useful.

vectorjohn··on Why I Strive to be a 0.1x Engineer
I guess all this rests on the assumption that Alice did something relevant in all that time she saved. If features A, B, C and D. Basically you seem to assume that each or some of those are relevant software development work and not just more WordPress deployments.

I guess the point is use pre-packaged tools when possible. But somebody has to write new software, so you better get some experience in doing that if you want to be a software developer.

vectorjohn··on Building AI
So what? We don't need as many. It doesn't make life any worse (in fact, probably better) for the ones we have now. Those pre-industrial-revolution horses would have been dead by now of old age if not turned into dog food.
vectorjohn··on Request For Research: Basic Income
Largest non-violent per capita prison population in the world? Not that much hyperbole.
vectorjohn··on Building AI
Yeah, and it's too bad horses don't exist anymore.

Oh wait. They are fine. They're just not used as constant slave labor all the time anymore, much like human labor.

And then ask, "what was your day job, because I don't need a wordpress themer."

I guess what I'm saying is that if your resume consists of setting up Wordpress sites, then you better like setting up wordpress sites because that's where your experience is.
