Quantum communications are definitely a thing:

Quantum computing is still at the R&D stage, but if you are an academic, that pretty much defines what "age" you're in:

> This is still so vague. I'm just trying to think about how some specific thing (eg, E = hv)[1] is linked to quantum mechanics as an OS.

I think the analogy makes sense in terms of what builds on what. You can build an application on top of an OS, you can't build an OS on top of an application.

With something like "E = hv" you are looking at an application; it's expressed in terms of kinematic concepts, none of which is intrinsic to QM:

Where I live they have been using really bright green paint to designate certain spots for bicycles. For example, where a bike lane crosses a car lane.

Lately I've noticed that with the accumulation of road grime and/or with the paint fading in the sunlight, the green no longer stands out. The painted areas are getting less and less obvious.

Point being, the idea has a lot of potential, but it is going to require a lot of maintenance. All that paint needs to be redone (cleaned and/or repainted) periodically.

Whereas if you put in a curb or physical barrier to demarcate where pedestrians can stand or where bikes should be, that lasts longer / is more permanent.
Ease of moving to the Bay area is probably a big factor too.

But couldn't it also be that big Bay area companies aren't more American than they are international?

That’s a very short sighted view.

We went to the moon at a period when we had many more problems on earth in fact we went to the moon nearly solely because of problems on earth.

The moonshot and the era of space exploration that of followed it enriched us beyond what most of us can comprehend and Mars won’t be any different.

We can never solve all our problems and human nature isn’t going to magically change over night we will have the same problems we are having here on earth else where and that is good because solutions that we might find to them on Mars or somewhere else might also be applicable here.
No, it would only have a state. In classical physics the state would be its Kinetic energy. In QE it would be.... well it’s state.

T is only defined in an ensemble of other particles, i.e. when you can no longer keep track the particles and it’s necessary to use averages. Then the T is the average kinetic energy.

Furthermore T is only technically defined in thermodynamic equilibrium, so nothing happens at all (otherwise you’re not in equilibrium).

Finally, you can have “negative temperature” I.e T < absolute zero, if you have population inversion (I.e. a lasing cavity) which is really an abuse of nomenclature since population inversion cannot occur in equilibrium (and therefore T is not defined). However, the Boltzmann (?) equations have pop inv. only when the the T parameter is negative (even though pop inv. is the “hotter” than infinitely hot).

All this to say that 1. T is not defined for a single particle 2. T is not well defined for very many systems at all!
Am I the only one who thought about motorcycle?
This author seems to have a couple problems.

One, they're complaining that we're going to pollute other worlds. I'm not sure that's a problem. I'm not even sure if we'll do it because of the delta-V requirement.

Two, they have a massive problem with animal experimentation, which seems to be a bit of a tangent, because that's the case across many industries -- the examples they give are from some time ago.

Three, the posit that there is life elsewhere in the solar system, which if it is the case, would be a good enough reason alone to explore the solar system.

Lastly, they comment on the thirty-meter scope fight in Hawaii, and this is where I completely diverge in opinion from the author. The author posits that Mauna Kea is a poor location for the telescope, but as far as I know, it's one of the best. I don't understand why the Hawaiians are so negative about scientific progress. I know their land is small, but the 'scope will benefit all of humanity for years to come, along with economic incentives. What's wrong with that?
I disagree a bit with you. In today's world we have reached a state where next new research output requires access to advance tools and strong funding which is only available to researchers at flagship institutions. There isn't any real research happening outside of flagship institutions; other institutions may make big claims on research they are doing but they almost never deliver output. In some sense, distribution of nobel prizes per country can be attributed countries research outout.
This looks really nice. But can someone recommend something more like "The Practical Experiments of Quantum Mechanics"?

I've read some articles and seen some video courses on Quantum Mechanics, and it seems that there's always way more focus on the mathematics and abstract/simplified physics, and not much description of the actual experiments. I get that the main challenge of teaching it is understanding the mathematics, but it's hard to stay focused when - even though I understand the equations - I'm not sure what the mathematics describes physically. Or when I do understand it, that I have no idea how one would go about preparing the state.

I think I've gotten a half decent understanding of the Stern–Gerlach experiment, but that's about it.

"This isn't evil; the company needs shareholder value to survive."

Viruses need animal hosts in order to survive. That isn't evil either. But if you're the host it's bad for you.

Companies as embodied in capitalism are generally bad for most humans in the long term. They are an irrational and little understood mechanism receiving un-critical, near-religious adulation.
You mean based on public-record statements by the President of the United States? Sounds like a pretty solid basis to base "speculation" on.
This depends entirely on the org. In many places with lots of engineers a broken build means hundreds of people are blocked n their work, it's bad news, lost productivity, slipped schedules, it's legitimately a high priority (page someone to fix this) issue.

But that's not always true, especially at smaller dev shops. However, smaller shops sometimes like to imitate the big corporations, it makes them feel more important, even though it's not necessary.

In both cases having broken builds in your production pipeline are an indication of a process or policy problem more than anything else, especially in 2018 when build hardware is cheap and CI platforms are everywhere.

(P.S. I've worked in both types of orgs. Ones where the builds had several teams of people working on them, where broken builds could mean huge amounts of lost or blocked work hour by hour and fixing builds was a very high priority task, and where there were huge systems and extensive policies designed to forestall build breaks getting checked into important branches. All of those systems and policies were built out of a history of chaos, where builds were almost always broken (if you have thousands of devs, and none of them take build breaks seriously, then there will almost always be one break checked in every day), schedules were unreliable, etc. So much so that it was burning people out. On the other hand I've also worked in places where a build break can be handled by filing a bug and letting it go through the normal process of triage and fix over a period of many days. Which process is appropriate is entirely dependent on context.)
You still seem to be taking it for granted that being surveilled is inevitable.
We took this into account and worked with data from multiple municipalities. 25 years of data in a region with 1 million people is quite a lot.

The problem for ML seem to be that we’ve been using the data for a while and that we’re already very good at it.

It solves the problem that the majority of firefox users is not blocking trackers

Is that a problem, however? Or more precisely, one that Mozilla wants to think is a problem and "solve"?

I use adblocking and such myself, but I think it should really be a personal choice --- browsers should just stay neutral. I have a suspicion that browser organisations taking sides in this will only lead to even more invasive tracking in the future, since this is a cat-and-mouse game. (Imagine if Firefox had adblock by default. It would just force adtech companies to come up with even more unblockable methods, since the defaults have changed.)
I can only imagine it has to do something with building activities over there, because the Google maps pictures have been edited to use only old 2013 pictures, and all the new ones in that frame have been edited with clouds over them, but all neighboring frames are not cloudy. so there was certainly something going visible per satellite.
Because they have idle machines and there would be money to be made.
Ah yes, the old argument that "the left" is the reason "the right" rose into power in the first place, as a reaction.

The "left" was never in power. All the hysteria about Obama fueled The Tea Party then Trump, yet he was never a progressive beacon. Obama is a true Democrat - an even-keeled centrist that would be barely "liberal" in most of the rest of the Western world. (Remember: NSA, drone strikes, was against gay marriage originally)

It's garbage. It was always garbage, and the only logical explanation i can find why the American right found so much to get excited about Obama is his race.

And now, it's a bully telling their victim that it's all their fault.
Doesn’t change the fact that it is already negated (with -less) and longer. No need for it to exist, like flammable and inflammable meaning the same thing, haha.
Indeed, the word has become nearly meaningless, but it doesn't seem to be rampantly overused on HN. Looking at titles, it only appeared 3 times in the last week on stories with any upvotes [0]:

AI Company Accused of Using Humans to Fake Its AI
AI Looking to Become Robot Mayor in Tokyo’s Tama City
AI Predicts Obesity Prevalence from Space

The 3rd one is the sort of nonsense I think you're complaining about. The first 2 are stories about AI as a business or cultural phenomenon, for which "AI" is the right term. So if we only have 1 story per week that uses it in a non-self-referential way, we can leave the pitchforks in the barn.

I would recommend avoiding adding your own global types if you can avoid it, for example TypeScript has a full type definition for Array.prototype.find [1]. You can enable it without changing the target and breaking things by adding es2015 to lib in your tsconfig compilerOptions

If you think the IS is a free and healthy democracy, then I don't know what to tell you. Our perception of hegemonies change as the complexities and subtleties are magnified now more than ever, but a hegemony now is not any different from one a thousand years ago.

America is as much a healthy democracy as the Roman republic.
oh, that was a surprise. thanks
People just need to use other services.

1) DuckDuckGo is great for search.

2) Protonmail is great for email.

3) gab.ai instead of twitter (heard about it but never used it; I guess twitter has some use...).

4) Voat instead of Reddit (it seemed to offer the same capabilities when I visited it a bit).

5) Facebook, nothing like this should even exist but I'm sure there is some alternative out there.
> There is a large difference in Europe between the taxation rate and what is paid in practice by corporations.

This is only true if you're big enough. If you're a small business, you pay the inflated rate or go to prison.
A lot of solutions required for Mars will benefit us here on Earth, of course technology alone won't allow the shift to happen. The problem with technological advancement is it gives an advantage, and who uses that advantage and for what purposes isn't easily controllable. This is why Elon rightfully fears AI so dearly. A bad actor that is malicious and intelligent enough could devastate us worse than anything in history and it could be a blindsided attack. If love is the answer, we need to learn how to better love and love more deeply.

Multiple large programs written in LuaJIT that have better performance than the same programs written in optimized C.

The vast majority of benchmarks I've seen are down to LuaJIT performing specific optimizations out of the box that the C compiler used in the comparison can perform but doesn't.

In particular the last time I looked at LuaJIT vs C++ benchmarks, the C++ compiler flags weren't set allow the use of SIMD instructions by default, but LuaJIT does.

There was another recent example I saw where LuaJIT was calling C functions faster than C in a benchmark. Then someone pointed out what the LuaJIT interpreter was actually doing, and how to implement the same speed up in C.

Java people made the same arguments years ago: "Java is just as fast or faster than C++". You'll notice that after 20 years of comparisons, no one who writes high performance code for a living makes that claim.

And without collateral you clearly can't loan to everyone because this is what happens:

Borrow money at 1000% interest

Don't make any payments. What are they going to do? Sue me? I can't pay, I'm in debt. Hookers and blow for everyone.

Borrow more money at 1000% interest. They can't say no!!! Debt for everyone!!

Make Payments? Lol.

Borrow more money. Don't make payments.

Borrow more money. Don't make payments.

Continue on forever. It's a money spigot.

Nobody would be willing to lend to anyone in this situation without serious collateral and only at very high rates and limited to low risk loans.

Reinstituting debtors prison would be the only fix for this problem. And that's 10000 times more oppressive than credit scores.

Don't lend to people in debt? Congratulations, now you're back to credit scores!
I feel like people are misreading this comment, which is asking how to avoid the pitfalls of dependent types, not how to avoid dependent types.
Looks like a case of damned if you do and damned if you don't. Privacy of health related information is critical, and as with other things, the people who are relatively poorer would be the worst hit. There's probably no escaping being further exploited or discriminated against.

If you REALLY believe in this sentiment fueling this article, then you shouldn't ever do anything. "We've made mistakes, and we shouldn't do anything until we're perfect." Fine, lay down and die, and the rest of us will keep trying to be better, failing often, but improving gradually.
> I don't understand why the Hawaiians are so negative about scientific progress. I know their land is small, but the 'scope will benefit all of humanity for years to come, along with economic incentives. What's wrong with that?

If you don't understand it's because you don't share their perspective—understandably. I think one of the things the author is suggesting is that we make a better effort to do so. Perhaps your idea of benefiting all of humanity for years to come is different than theirs?
I don't think large amounts of force is what you mean here, but energy instead.

You can escape the galaxy if you apply a very small force over a very long time, or a larger force over a shorter time.
I don't think you understand VAT.

If you buy some computers for $100, do some work, and manage to sell your services for $1000, you get to reclaim $20 of VAT but you have to pay $200 of VAT, so a 20% VAT rate costs this hypothetical business 18% of its revenue, which is hardly "unimportant".

And a typical tech company would be taking in far more than 10x in revenue than what they are spending on VAT-able goods.

EDIT: But see below.
The phrase "I could care less" is similarly accepted, but that will never stop me from judging people who say it.
Ask HN: Any recruiting platform like hackerrank supports MVC frameworks, DBs?

It also, assuming it follows Baker's original paper[1] (which I believe it does), allocates all objects on the stack, maintaining the invariant[2] that nothing on the heap points to anything on the stack, and nothing in an older stack frame points to anything in a newer stack frame; and, to maintain this invariant, it kicks things out of the stack and onto the heap whenever necessary. The stack thus serves as a nursery in a kind of generational GC.

Overall a good post... except for that first line 'Everything in software development has already been invented' Really... everything? I don't buy that but do agree with the sentiment expressed in the rest of the paragraph that people keep rediscovering/reinventing things. Computing is a field with very little long term memory.
I looked in the logs. That comment was never [dead] and then unkilled, so I'm not sure what you were seeing?

In any case, you posted this 5 minutes after the comment appeared. That's not enough time to conclude anything about HN, other than that trolls sometimes post here, like they do everywhere on the public internet. It takes time for the community systems (voting, flagging, and moderation) to take effect. It would be nice if we could make them work instantly, but we don't know how to do that. As you can see, the comment is now flag-killed. No single comment can say "a hell of a lot" about a site where 8000 comments appear daily, but since the community functioned as intended in the end, we can count this data point in its favor.

But there's a more important point. Since you're participating here, you're part of the state of the site, and we need you to help take care of it. In the present case that means flagging an egregious comment, instead of feeding it by replying, which only makes the site worse. This is in the guidelines: https://news.ycombinator.com/newsguidelines.html. Had you contributed a flag, you would have helped take care of the problem sooner. Fortunately other users came along and did, thereby improving the state of the site. If you'd be willing to help out like that in the future, we'd appreciate it. But in any case, please don't feed the trolls on HN. The more you do, the more responsibility for the flamewar accrues to you, regardless of how right you are. This is ancient internet wisdom for good reason.

To flag a comment, click on its timestamp to go to its page, then click 'flag' at the top. There's a small karma threshold, currently 30, before flag links appear. This is in the FAQ: https://news.ycombinator.com/newsfaq.html
I can see how the clause could be read that way, but if you read that clause in the context of the entire document, you'll see that it has a much narrower meaning.

For example, the contract clause also has a different part that prohibits states from coining money. In article 1, section 8, the constitution grants Congress the power to coin money. Read together, this means that a state can't issue money unless that money is backed by gold or silver.

There are some fairly weird edge cases in this rule. State banks can issue bonds, and those bonds can be privately tradeable, which is quite a lot like issuing money. However, according to the cases that Wikipedia cites, that's perfectly legal.

It's interesting how much of the Constitution is about creating an economic alliance, as much as a political or military one. Having federal bankruptcy courts, a postal system, banning tariffs on interstate trades, or a copyright system is really about creating a single common market with closely integrated economies. We don't generally think about those aspects of the Constitution, because we're so used to it.

What are things? Is money a thing? Can PayPal decide to lock your account and not give you your money back? What about selling your data to other companies? Are those things. You bought media on Google or Amazon and then they close your account because you criticized them on social media. Is that media "things"? See it is a bit more nuanced in today's world than just saying well they didn't knock on your door and took your microwave away, so qualitatively a different situation.
The idea of functional core is cool. I find domain-driven design a better guide for implementation. In a nut shell, there are three types of objects: value, entity, and service. Both value and entity are functional and stateless objects. A service object maps between stateless objects and may cross the domain boundary (such as network, IO, etc). When I do this in java, a service object would have interfaces returning CompletableFuture of Value or Entity objects.

I wonder why upper management keeps designing them so poorly too. I mean, in concept the interoperability of a buzzing idea sharing space is great, but the concentration zones are almost always so shitty that nobody uses them, and even if they do, the concentration bit is often ignored by corporate culture.
