The problem with releasing a video is the outrage it provokes.

The benefit of releasing a video is the fear it provokes.

Not saying this is the case here, but obviously if you calculate outrage cannot grow substantially greater than it already is, might as well try provoking some fear.

Of course it might very well be false, this is just my idea as to why someone might release it if real.
It's well known that the trickle-down theory is utter codswallop. The marginal propensity to spend, and spend locally, is higher among the very poor.

But I suppose it's always good to get some quantitative confirmation.
I think you've picked a bad example to make this argument about. "China is a scary country" is an unsubstantive negative statement about an entire country. It isn't nuanced. It's not qualified in any way. That easily falls under whatever moderation rule we might apply.

People often seem to think they're making nuanced factual statements when they're actually making blanket emotional ones. Those have degrading effects on discussion here when they're about entire nations, entire classes of people, and so on—and they're easy to avoid if one chooses to.

Part of the issue is that HN threads feel like intimate conversation—which is wonderful and something we consciously cultivate. But it's all fully in public and the audience is large and highly international. Because that gap isn't obvious, it leads people to say things which might be inconsequential in a small group, but are just the opposite here.

It only takes a little objectivity and/or empathy to get what it must feel like to come to HN and encounter putdowns of one's country or one's demographic. That's not cool, and fortunately it's not necessary, so commenters here are responsible for clearly disambiguating their comments from that.
Obviously the problem is with using objects in the message which are invalid. The compiler may or may not work as you expect and that’s your problem, not the compilers.

You can try to defend yourself by stating the call is done by some framework but that just means the problem is still not in the language, it’s in the framework.
I had been listening to some "Game A" vs "Game B" podcasts - Schmachtenberger, Hall (Greenhall), Rutt, etc, just before listening to this podcast. For example: https://soundcloud.com/venturestories/game-b-in-a-silicon-va...

These thinkers propose a common constraint for stagnant growth in education and medicine: a philosophy of science. There is much more to it, and unfortunately it's not a concise explanation. However, I find this conceptual frame much stronger than the education/medicine problem "commonalities" described by Zuck, Collison and Cowen. Further, the "Game A" insight seems to predict the shortcomings of an applied meta-approach of "the tool-building which comes from having the experience building engineering teams."

Game A: ("hill climbing") invest in better microscopy tools, even though "right now, the actual technology of microscopes is ahead of scientists’ ability to process the data".

Game B: ("valley crossing") invest in a philosophy of science to better understand complexity management, causality and sense-making in the domains of education and medicine.

"And as engineers.. you really want to get into the code and step through it to see where the thing is breaking down" (Zuck). But whats 'broken' at FB? is it a server infrastructure? monetization? or is it interpersonal psychology of user relationships? Mistaking our tools' observation for reality, and optimizing for only what we can measure can build profits, but it has limits to make sense of complexity - and undefined/unmanaged complexity is common to the nature of education/medicine problems.
The citizens thing is really weird. On investigation, the cap is three max, so one slot remains.

I'll tell you how it's done at my Vons and Ralphs in my neighborhood in LA. They hire private security, one during the day, and two at night. They have to fend for themselves, as even if someone gets stabbed (like what happened to two people at the ralph's in september), cops aren't going to get there until blood has been spilled and the assailant has disappeared.

In the case from September, the suspect still hasn't been found, even with security footage and multiple witnesses and a description. Even at the vons, my regular shop on account of the stabbing at the ralphs, about once every other month the security guard has to bear hug and haul out a destitute person who decided to get belligerent with a cashier or customer. And this is a neighborhood that commands 1br rents north of 1.8k, but functions like Mos Eisley.

The solution is some sort of hired security, whether police or private. The ralphs situation could have been much worse without security guards.

The same document defines `in-addr.arpa` domains that have numeric labels.

The mandate of a starting letter was for backwards compatibility, and mentions it in light of keeping names compatible with email servers and HOSTS files it was replacing.

Taking a numeric label risks incompatibility with antiquated systems, but I doubt it will effect any modern browser.
Note that the addition is commutative [1], i.e. a+b==b+a always.

What is failing is associativity, i.e. (a+b)+c==a+(b+c)

For example

(.0000000000000001 + .0000000000000001 ) + 1.0

--> 1.0000000000000002

.0000000000000001 + (.0000000000000001 + 1.0)

--> 1.0

In your example, you are mixing both properties,

(.0000000000000001 + .0000000000000001) + 1.0

--> 1.0000000000000002

(1.0 + .0000000000000001) + .0000000000000001

--> 1.0

but the difference is caused by the lack of associativity, not by the lack of commutativity.

[1] Perhaps you must exclude -0.0. I think it is commutative even with -0.0, but I'm never 100% sure.

Unless you have a floating point model that supports arbitrary bases, you're always going to have the issue. Binary floats are unable to represent 1/10 just as decimal floats are unable to represent 1/3.

And in case anyone's wondering about handling it by representing the repeating digits instead, here's the decimal representation of 1/12345 using repeating digits:

>> At least the poor would have the choice between the barely livable pod in downtown, or a house 2 hours commute away.

Okay, so build normal size apartments then. Even if it's the same price as a house 2-3 hours away, you're removing 3-6 hours of commute time.

The important part is splitting land costs over tens of units instead of just one or two, not exactly how many tens.

Then I feel like I really must be dense. Doesn't this mean that there's still an incentive to hoard land while nearby land is improved, so that you can sell at a profit? And if that's the case, for the purpose of dissuading land hoarding and encouraging building housing how is a land value tax functionally different from a property tax? In both cases if you have an empty lot in an area that gets built up, you make a big unearned profit, right?
Private life gives you an environment where you can meet people that you can be friends with too, maybe more than the office where you have to do several other things too. Like work.
Physical quantum computers have noise. Let's take a (simplified) scenario. You've set up your quantum circuit with one qubit, and put it in a position where it will measure as either 0 or 1 with equal chance. In the simulation it'll come out as 0 or 1 with actual equal chance. In the real world, other factors will create a bias one way or the other (this may not be consistent, either) so that it comes out more like 60% 0 to 40% 1, even over 1000s of trials.

If you set up a circuit where you've entangled two qubits so that they should come out as the same value (00 or 11) and the configuration says they should come out with 50% chance of either, the simulation will show that. The outputs of 01 and 10 will never show up in the simulation. But in the real world, there's still a chance that you get those. You'll likely (on IBM's quantum computers) get something like 1-5% 01, 1-5% 10, 45-50% 11, 45-50% 00 (again, over thousands of runs).

If you want to see how this plays out with simulations and real quantum computers, IBM [0] has free access (constrained by credits when you want to run on real quantum computers, they reset each day).

Yeah, I just don't agree. I don't think you (or we) get to decide what makes someone feel that hacking feeling.

There's a term for not finding "you can run an embedded linux under 10 minutes with less that 20 bucks with a RPI by reading some tutorial or watching a youtube video" exciting: jaded. "What's the fun about that?"... seriously, dude? Listen to yourself. It's only not fun because you've done it so many times. It's fucking incredible.

News flash: the fact that you were able to be alive at a time when C64s and XTs were happening, that you had someone who loved you in your immediate family that could help you if you got stuck was an enormous privilege.

I challenge you to explain to me how someone today learning to hack a Pi from a Youtube video even though their parents are manual labourers and electricity isn't always available is somehow less hacker than you ever were. Get out of your own head.

Don't even know where to start with this--with all due respect this reads as textbook dunning kruger You aren't a trained medial expert. You lack the years of training and experiance somebody in the field has. Just like any other profession, that training is there to help you filter out how to properly think about the problem-space you are in and filter out all the noise. There is no-doubt a lot of unstated things that those youtube videos dont talk about that an untrained random person like yourself simply doesn't know.

You lack the internal knowledge-base that somebody with training has and therefore you are much more likely to mis-diagnose yourself, fall into an edge case that somebody with training could have easily caught, or miss something very important because it wasn't stated in the video you watched.

I dunno man... when it comes to the medial field I personally let the experts do their work. Relying on the internet, which is especially full of superstition, noise and pure bullshit when it comes to medial information, seems like setting yourself up to get hurt. But maybe that is just me...

No. We’re still a long way from quantum computers powerful enough for that.
I'm open to data and a serious analysis.

That said, it's hard not to see such complaints as a combination of entitlement and cluelessness. As a Boomer, I never would have considered taking on college debt without a pretty clear analysis showing breakeven in a reasonable period. The idea of getting an arts degree crossed my mind, and I dismissed it as ridiculous within a couple of months.

Most of my friends went straight into the military, the trades, or general employment. State college was for maybe the top 20%, and I'm not sure I even knew anyone that went to a name school.

Work? Full time every summer starting at 16, and half time while school was in session. Housing? Live at home, or maybe the cheapest dorm. Car? Find a friend and give them gas money. Phone? Picture an Obama phone that's nailed to the kitchen wall and shared with three other people.

By today's standards, Boomers were not well off. Even so, most of what I've earned has already been transferred to the following generation.
Great find! But why on earth is there no mention of git, or the other VCSes? IMHO they’re a huge reason for using plaintext for more purposes.

Even if Amazon had worked out an agreement with Google to run arbitrary algorithms on a 53 qubit computer; that would not be enough to run Shors algorithm (which only breaks RSA and Elliptic Curve) on normal keys.

Sort of... Transmeta was basically a VLIW chip optimized to recompile x86 code. The problem was by that point all x86 chips (even plucky little VIA/Centaur!) were recompiling x86 instructions into RISC-ish ones, and without sucking up RAM and more importantly memory bandwidth to do it.

So even if the VLIW chip was on paper more powerful/efficient (and I'm not sure it was), it just couldn't keep up with doing it in hardware.
One small tip about printf for floating point numbers. In addition to "%f", you can also print them using "%g". While the precision specifier in %f refers to digits after the decimal period, in %g the precision refers to the number of significant digits. The %g version is also allowed to use exponential notation, which often results in more pleasant-looking output than %f.

printf("%.4g", 1.125e10) --> 1.125e+10
printf("%.4f", 1.125e10) --> 11250000000.0000
