"My own personal opinion is that time is a human construct"

What is this supposed to mean?

We can measure time with non-human instruments and time is at the core of physics. How can it be a human construct?

Sure, hours, minutes, days, etc. are human constructs based on movements of the earth, but time itself?
Well, any sort of process control too (as in, controlling an assembly line or a chemical plant).
It could be that the crypto part is just incidental, the BIS press release doesn't really make much of a fuss about it. They focus on the duration and repeated non-compliant actions.

It sounds almost like they're saying 'if you screw up once or twice up but self-report quickly, we'll send you a sternly worded note but if you tell us you've been violating the regulation for years we're obliged to give you a firm but not too painful slap on the wrist'
Pretty cool. If the thing could carry a single car, and the system would allow one to lower the center section so that one could drive on and drive off, I could see it as an interesting addition to cross bay traffic. Going 30 knots on the water straight from the say Moffet to the Embarcadero in SF could conceivably be faster than trying to navigate it that way by freeway.

Ask HN: Cheap and Cheerful Laptop for BSD/Linux: what are my options?
In the title. I have a 11" 2011 MacBook Air (which I feel is one of my best consumer decisions to date, and isn't going anywhere) but I'm looking to purchase a cheap laptop that I can just run into the ground. It should be compatible with Linux/BSD out of the box. That means integrated graphics and solid network interface cards. What are my options?

Edit: Battery life is not an issue. I am tempted by a cheap desktop, but I hate the idea of having cables everywhere and a great big stinking tower under my desk.
This sort of thing has been cropping up in distributed systems quite a bit recently, in the form of CRDTs: commutative replicated data-types. Essentially data structures whose operations commute. This offers a lot of powerful guarantees when it comes to dealing with consistency in a distributed system.

They're an interesting concept, and I'd highly recommend reading more about them.

Great, so now you can outsource being an asshole? This guy needs to suck it up, pay his tickets, read the signs, and stop driving and parking like a moron. Best approach for people who absolutely cannot be bothered to read and follow the rules would probably be to sell the car and join a car sharing service where the parking spaces are dedicated.
I assume the protocol is designed such that you cannot record a response and then replay it later. If that's true (and I could be way too optimistic here) then an attack like that would require two confederates and some communications hardware, with one guy on the street scanning people's cards at the exact same time as the other guy presents his end of the equipment to the local point of sale. This is all doable, but it doesn't scale too well.
As I understand it, you can't actually use this to transmit information. If you entangle two particles, and then send one away, and attempt to measure the appropriate property (I think it's spin), hurray: you know that the other particle's spin is the opposite.

But that's not communication. It's like slicing a coin down the middle without looking at it, hiding each half in a box, and giving one of the boxes to someone going to the moon. A week later, you both open your box, and you know exactly which side of the coin the other person has - but that's not communication.

My God, but "Story of Your Life" is a marvellous story. I'm not sure that it's the intended effect, but I read it at a very stressful time in my life, and it had a marvellously calming effect.

Both "The Merchant and the Alchemist's Gate" (not science fiction at all) and "The Lifecycle of Software Objects" were fine, but, for me, nothing touches the shock of reading that first story.

(I think that perhaps the greatest recommendation that I can give for Chiang is to say that, for a long time, I remembered "The Infinite Assassin" as being his story.)
The sad thing is: This framework isn't really fast. Just by virtue of being C++ nothing gets faster. Have a look at the web framework benchmarks:

But you can predict and account for relativity; We already have good protocols for dealing with expected drift. NTP already takes into account that your PC is not keeping time as accurately as the upstream servers, and keeps a driftfile that guesses at the time differential needed. The NTP daemon silently adjusts the time every second to deal with this.

If two clocks are at different heights, they can compute the differential in their rates and agree on a time unit. Sure, it might be 1 quadrillion ticks in on one clock and 1 quadrillion and 1 ticks on the other, but it's still a 'second' so long as both sides see it as simultaneous.

I think I know why you're getting down-voted, but it's an interesting and real issue.

If you go a while, mostly digesting only tiny chunks of information, your brain optimizes around that and eventually becomes bad at dealing with longer narratives. (Aside: sometimes those narratives are worthwhile, other times they seem like they're just filler to make editors and publishers happy. But that's beside the point.)

It's also something we seem to be losing as a society.

The good news is, at least in my own experience, it's a skill we can develop (and it's closely related to attention span). When I buckle down and read complex texts for non-Internet periods of time (20-30 minutes), I quickly regain my speed and comprehension. But I find it important to deliberately exercise that part of my brain.
Well with contactless payments a unique CVV is generated by the card for every transaction. The attacker would have to steal the card info, CVV, and use it to purchase something before the victim uses their card again or the card will automatically be disabled by the payment processor. In any case they can only make a fraudulent purchase once for every time they trick the card. That's certainly better than the current situation where once your card is compromised you are screwed.

Hi, benologist!

The area-specific feature goes beyond just where the startups are based. We focus on companies that offer a unique product or service primarily to people in their area. Think Instacart or Postmates, before the expansions.

Why? We feel that with the boom of neat startups across the US and further, people in the same area are sometimes the last to find out! The broadcast is far and wide and often ends up circling back to the locals, as opposed to beginning with them. Acquainted aims to create an easier way to connect new businesses and their surrounding customers.

Hope this helps!

Well, as I recall, Sam, from one of your lectures
in your current course at Stanford, both Marc
Andreesseen and Ron Conway made it quite clear that
they no longer take proposals from "over the transom"
and, instead, learn about new investments only
from their "network". Sounds quite closed and not very "open" and,
instead, like an echo chamber from the past
with not a very good view of the future.

Or, NSF, NIH, and DARPA will take proposals from
strangers, but not Sand Hill Road.

Angular scales up fairly smoothly from a small widget on a site to a full SPA. It has two major downsides.

- you're on your own for a lot of app structure

- it expects you to know javascript quirks about object references, prototypical inheritance and how to read JS stack traces

So Ruby on Rails developers find it quite unfriendly -- few conventions, very different rules about passing data around.

Ember.js has more structure, but it's difficult for a new user to use without something like EmberCLI (http://www.ember-cli.com/) to generate the basic app. It's incredibly frustrating without it since nothing will work until everything is named correctly.

Personally I find it's much easier to get things done in Angular.

However because you can learn Angular by muddling through the docs the community isn't very deep. Ember developers need to keep in touch with each other to understand the ideas behind the framework and changes to it.

So Ember meetups are much more interesting.
Even in relative terms, the top of Mt. Everest is traveling faster than objects at sea level, no?

Wikipedia says: "Time dilation is caused by differences in either gravity or relative velocity. Both factors are at play in the case of ISS astronauts (and are actually opposing one another)."

Why wouldn't the same apply to the top of Mt Everest. Sure, unlike the ISS, Everest is actually attached to the Earth, but still it is traveling a longer distance than the oceans over the same period, and therefore would be moving faster in relative terms AFAICS.
The flip-side to this is that the Android versions of these apps aren't getting anymore love. Messages is now Hangouts, Browser is now Chrome, Calender is now GCal. I heard that the Gmail app is going to start allowing Yahoo email accounts too. Android is much more locked down than it once was.

Sadly no. That would be a convenient and nifty way to vary frequency for ham radio applications if it were the case. Even just a couple dozen PPM in a magnetic field would be sufficient for transmit receive switching but it just doesn't work. Also if that were the case mounting a crystal nearby a power transformer or fan would generate massive noise in the output signal unless magnetically shielded, which also doesn't happen.

I would imagine magnetizing a mechanical watch would really mess things up, so at a "just under really messed up" threshold it would probably have the claimed effect.

You may be thinking of YIG garnet oscillators which are very dependent on magnetic field but they haven't been common tech in maybe 30 years. Even used on ebay they cost more than modern new microwave VCOs which is annoying. I have a box of old YIG osc in my basement which I actually used for ham radio experiments before modern solid state VCOs took over.

My employer (German) just banned all Google products (except search) for work-related things, due to privacy issues. Reading Google's latest terms-and-conditions, this move is somewhat understandable, given the strong privacy laws that German companies and institutions have to follow.

On the other hand, I guess that scanning a large amount of emails is the precise thing that allows them to offer robust email-to-event conversion. But I wish that this sort of thing would work locally (on the cellphone or computer in question), not on a remote server somewhere.
There is no absolute velocity, but there is absolute acceleration. And the mountaintop is accelerating more because it's in circular motion with a larger radius.

However, the effect of gravity is much more significant (if it weren't, the mountaintop would be flying out into space due to centripetal force).
> My gut is Google think this is the only way to get iOS users to switch

Huh? I've been an Android user since the days of the Moto Droid, and I really like the design direction they're taking. It's clean, it's not full of crappy, drastic gradients and obscene amounts of clutter. Some of the menus/lists are organized better now, which I greatly appreciate. The Music app is actually bearable now. The Gmail app is better than ever for my usage cases.

The only thing that annoys me is the new Message app removing the ability to swipe convos off when you are "done" with them. But that's a small little annoyance to get all of the other goodies.

I'm sure there are others that hate it, but it's not like everyone does. I'm more satisfied with my phone now than I've ever been.

Is it loosing or losing? Are both correct?
You think so? I've had discussions on the topic of warfare off and on throughout the time I've been on HN, and they're usually pretty respectful. Indeed, I think that's one of the unique things about this place.

For example, a couple years ago, I had a discussion about drone warfare -- https://news.ycombinator.com/item?id=4957015 -- that covered very similar conceptual ground. I thought it was pretty civil.

Indeed, I would have thought the technologization of warfare was something of general interest to this community, and a legitimate topic of discussion -- being at the intersection of technology and interesting changes in the way the world works. I didn't think it was just stupid politics, but that can be a landmine...
That's the common explanation, but its apparently wrong. There is not a fixed state of each 'quarter' in each 'box'. They are truly not determined until one is resolved; then the other is resolved simultaneously. Still, not communication.
Fabulous stuff.

His comment can only be read as "advocating warfare and violence as a solution to nation-state conflicts" if the reader injects it.

If we can add a layer of conflict-resolution between open diplomacy and global thermonuclear war, there's something to be said for the fact that it may provide additional margin before greater escalation occurs.

That's not advocating for war/or violence, that's just responsible conflict-resolution.

It'd be just as fallacious as my saying anyone opposed to cyber warfare must prefer that we cut to the chase and nuke the globe.

You can oppose cyber warfare but also prefer it to something you oppose even more.
Wait... IKEA??? $489??? SOLD!!! Don't even need to know anything more... SHIP IT!!!
Probably not. You're looking at a height difference of about 9 km [1], at a radius of 6380 km from earth's core [0] versus about an equatorial 6371 km. Rotational velocity at the equator is about 1040 mph [5], while Everest is looking at about 6380 km / 6371 km * 1040 mph = 1041.5 mph, assuming we moved Everest to the equator and kept everything else the same. One or two mph is really small compared to c, so much so WA just sorta says gamma = 1 [4].

And so is a mere 0.15% increase in height. But compare the gravitational acceleration at these two heights:

[2] Everest = 9.76322 m/s^2

[3] Sea Level = 9.831 m/s^2

Sea level is 0.69% stronger. That's somewhat more significant, and given that gravitational energy follows the inverse-square law, it makes some sense that it would amplify differences more than the linear effects of speed.

EDIT: forgot the reference to rotational velocity (and spelling).
Note that the point is scale here. Gravity is n^2 versus velocity's n. It'll have a stronger effect in most cases (and any where speed overcomes, well, we call them relativistic speeds, and they'll often be some appreciable fraction of c, like 1% or more).

DOUBLE EDIT: 'AnimalMuppet makes a good point that the entire estimate for Everest's rotational velocity is flat out wrong. So I've changed my premise to match my initial incredibly incorrect assumption.

If I were to attempt to be correct about the problem, we'd see that Everest is cos(27.9881 degrees [10]) = 0.8837 [11] as fast as the equator, which sorta blasts out any height changes by long shot. (Note I'm assuming the earth to be a perfect, frictionless sphere here, and definitely not a oblate spheroid.)

I agree. I am an ex-trader in his late 20s, and most of my peers who stayed in finance have at least a million dollars in savings+assets.
Is the top of Mt. Everest traveling faster? The distance between here and there is a constant, no? From my frame of reference it's not moving at all.
I think his point is that time is so inherently relative to the location / inertia of the observer that it is in practice a human construct.

Isn't it possible for the astronaut to also know whether the other person has opened their box? If yes, then this is where the analogy breaks down. However I'm probably remembering incorrectly. I just thought there was some property like "It's possible to detect whether the other person has made an observation yet."

I'm probably mistaken, because if this were possible, then you could use it as a 1-bit communication. "If you detect that I've opened my box, then blow up the moon. Otherwise, do nothing."
