There's a wall at my parents house which to me always looked green. I referred to it as green and my sister and mother seemed to get downright angry, insisting it was blue. I don't really care either way, it just looks green to me. I can't stop seeing it as green.

If you were to analyze the wavelengths of light the wall, or your notebook, consist of, you'll find a certain amount of blue and a certain amount of green. The thresholds which are detected by our eyes, and the thresholds relative to that where we subjectively determine the dominant color, has high variance.

But people take their subjective perception dead serious, since their perspective is the only one which matters.

On power drain, it's an internet phone, the GSM/LTE module only needs to be active when you're not in range of wifi. Which for certain use cases such as being at home in an office, much of the day it can be switched off.

Giving them the benefit of the doubt, they may have started with crowd supply so they didn't have to worry about certain things (credit card, shipping) that crwod supply took care of, but took a portion of the proceeds. Now that they have done kickstarting a few times, they understand better how it works, or they are large enough that crowd supply no longer makes sense.
I still think you are overstating things. Stefan-Boltzmann is just a fancy way to
say radiation. That is more or less a solved problem with nested shells. Each layer of shell cuts the losses in half. But let's ignore that for now, since more than one layer of shell complicates construction.

Historical aside: before we had good solar panels, people tried crazy stuff like the Phaeton satellite that used a generator spun by a heat engine powered by liquid mercury heated by parabolic reflectors. Let's bring that idea back.

1MW only requires a 30 meter by 30 meter thermal solar collector. Pump that 1MW of heat into the hab and run a heat engine, using the shell of the hab as the thermal sink. Now that constant 1MW drain is a required feature.
Anecdotal evidence but the Whole Foods I have visited in the Boston area are a lot less crowded than other supermarkets.
Anyone whose jaw is on the floor in horror at this post, be advised that it's not some hyper-connected techie outlier: this is absolutely the norm now.

My wife teaches in a mixed lowish-to-upper-middle school district in (what I'm sure many of you will consider to be) backward-ass Kansas City. Most of the kids have a personal smartphone by 2nd or 3rd grade. All except a tiny minority with stricter parents have them by 5th or so—we're talking 1-2 a class without a personal smartphone, tops. The school abandoned efforts to keep phones out years ago, and I've been told that's how most are now. Taking a phone being used in class will just earn you a pissed-off self-righteous parent who may or may not turn out to be a nutter who tries to get you fired, so no-one even tries, and besides, school policies on phone use are weak—they've just surrendered, because almost no parents would back them up on any kind of anti-phone policy with teeth, and many would actively fight it. My wife's many times had to scold kids for texting their friggin' parents while lessons are going on.
It was. That summary is a bit of a simplification.

Yes, that is where we are missing each other because fixating on some subset of the office space in the area ignores the reality both for the metro area and Seattle proper. The metro area is what matters economically and office space should be evaluated in that context. We can discuss the impact to the city itself of its share of office space in the metro area but focusing on this little piece of the puzzle is a distraction.

Mars has the radiation problem while in-transit, which is still unsolved.

We have already gone to the Moon. Given that the travel time is relatively short, radiation is far less of a concern.

This is why the Moon is attractive. We know how to get there already and it's not too difficult, all things considered. The problem of how to get there and back with humans aboard has already been solved. It's never been done to Mars.
well I didn't ever like homework either. I failed classes because I was up all night programming. I hated homework because I was hungrier to work on something more interesting. Not because I didn't want to learn. I believe in letting people follow their calling. For some that means not wearing a seatbelt or becoming obese and that does not harm me. Toddlers is a different story. If a toddler throws a temper tantrum I believe in comforting. With an animal you'd lock it in a crate.

On Formally Undecidable Propositions... by Kurt Godel.

One might argue this is not CS, but it's something everyone should read and understand.
> You are still misunderstanding the concern. The problem is not poorly trained drivers. The problem is that humans become less attentive after an extended period of problem-free automated operation.

I understand the concern. I am saying the problem of slow return from periods of extended inattention is not significant in comparison to general human ineptitude.

Level 2 systems may rely on "humans serving as a reliable backup," but they won't always need their humans at a moment's notice. Being able to predict failure modes and (a) give ample warning before handing over control, (b) take default action, e.g. pulling over, and/or (c) refusing to drive when those conditions are likely all emerge as possible solutions.

In any case, I'm arguing that the predictable problem of inattention is outweighed by the stupid mistakes Level 2 autopilots will avoid 99% of the time. Yes, from time to time Level 2 autopilots will abruptly hand control over to an inattentive human who runs off a cliff. But that balances against all the accidents humans regularly get themselves into in situations a Level 2 system would handle with ease. It isn't a trolley problem, it's trading a big problem for a small one.

I can confirm that manufacturers will haggle over a few cents, or even fractions thereof, for e.g. a sensor in a product that will finally cost thousands of dollars. I suppose they see those cents adding up over hundreds of thousands of prospective sales. Still, it certainly looks kind of petty.
Thanks for correctly saying "these data" in the menu
This looks incredibly similar to https://www.ventusky.com/ doesn't it?
Data specific to driving is still quite limited for people, even when counting all that passenger time in childhood. The average driver in the US drives maybe 10-15k miles a year, so optimistically a person may have 200-250k passenger miles before driving? Consider that Waymo's cars drove 3 million real world miles in 2016 alone, and 25 billion virtual miles in a simulation, and all those miles are potentially used in a model shared by all the cars.

Now if you want to just look "total experience in the world as a whole" the numbers look a bit different, but if anything that just accentuates the differences here. We don't currently have a way to teach computers to construct mental models of how the world works the same way humans think about it, which would be necessary to use training data that was about the world as a whole.
std_throwaway got the reasoning right in higher comment. You're actually doing a comparison if the object references are identical, not if the values are identical.

The tricky bit is that everything is an object in Python, even "primitives" like integers, which can be surprising coming from some other languages. Then the trickier bit is that CPython (the most popular and standard implementation) on startup creates an object for every int from -5 to 256 and will re-use those instead of creating a new PyLongObject. This means that `256 is 256` works, because under the hood, it's short-circuting it to the same object. But `257 is 257` creates 2 different PyLongObjects, which have the same value, 257, but aren't technically the same object.

And in my above example, the reason `x = 257; x is 257` is True when on the same line, but False when on separate lines (in the REPL) is because of the reasons kmill says, the constants pool that the interpreter creates. If they're interpreted together, it will create and use the same constant.

Here is my entry on my company's blog about this. I won't guarantee you it's well written, but it does show bytecode and has links to the relevant C source lines at the very end.

Hello!

I am curious about a couple of things:

Assuming you use Intel chips, how do you manage to trust the firmware/ME from them? Do you write your own BIOS to ensure that it is safe? Or do you use ARM/PowerPC/other ISA and have an entirely open source stack?

Does the Titan assume no phyiscal access? And if you do assume someone could steal the chip/try to reverse engineer the chip, do you have anything in it to stop an adversery? I would wonder if there would be a private/nation state agency would want access to certain secrets so bad that they would try to alter it physically, rather then through root access.
I'm pretty skeptical Amazon knows how to run a premium grocer. I hope they didn't do this only cause they saw Whole Foods as a way to super charge their prime pantry program.
Hmm, I don't know. Especially the way the segregate RAM into banks reminds me a lot of the x86 segments with their direct and indirect addressing modes.

Also a lot of instructions have similar names: CLC

You are right, it is not a true ancestor, but ready through the manual, it did seem to me that it was designed by the same people.

To be honest I haven't dig into other CPU families, so maybe these were pretty common.

But I can definitely see 4004 DNA in x86.

I immediately checked to see where my top bar color was, since I've had it for several years. It's a kinda nice hex number, but one which I did hand-pick for it's color properties, so I doubt that anyone else has chosen this color. It's approx. #600 down the list, meaning that it and the 300 colors below it are used uniquely (at-least).
I know of no one personally who shops at Whole Foods for anything other than specialty items. Hell, my last 10 trips in the past 2 years were nothing but falafel, hummus, and beer.

>Everybody should be able to eat Whole Foods Market quality

Strange. Last I heard Whole Foods has made no effort to get this quality of food into the hands of 7.2 Billion people that aren't Americans.

But you can't have it both ways.

> UK law very definitely requires you to stop shooting immediately once the danger is past

US law as well. If an assailant is obviously incapacitated or surrendering, it's illegal to keep shooting them.

That doesn't really conflict with what the grandparent post says: self defense firearms instructors typically teach students to fire multiple shots at the torso of an assailant, often to continue firing until the assailant stops being an obvious threat. It's risky to shoot someone who's attacking you and stop to see whether it worked.

As an example of the reasoning for this kind of instruction, here's an account of a gunfight between a police officer and a murder suspect. The suspect continued shooting after taking several bullets to the chest and tried to drive away after being shot a total of 22 times.

I try not to think about the topic too much because I like the occasional spot of cheese, but the number of calves that get slaughtered each year to enable milk production is mildly disturbing. Even worse, some countries have regulations against selling animals under a certain age, and the milk's worth more to a farmer than the month-old calf, so you end up getting piles of male calf carcasses thrown into pits for composting.
