The article compares the hypothetical amount of data to be stored in a NSA data center to the records storage area of the Stasi.

That is, a guess at the amount of data one facility of a modern signals intelligence agency (belonging to a super-power) is being compared to the amount of record keeping space a cold war era security agency (belonging to a Soviet client-state) possessed. The two agencies have vastly different missions (state security versus signals intelligence), operated at vastly different scales, and in completely different eras. The two facilities being compared are not at all similar. A large computing facility (probably processing raw data) is being compared to a large library archive (largely storing files and documents generated by the agency).

No valid conclusions could possibly be drawn from this comparison. The closest we could come to a valid conclusion is; if we printed out 5 zettabytes of data we would have wasted a lot of paper.

Edit: What I'm trying to say is that this is an apple to oranges comparison made across space and time.

What I've been wanting to see is how puma threads compete directly against unicorn workers ... so as an exmaple ... how puma with 4 threads does vs Unicorn with 4 processes? I can't find that particular comparison anywhere.

For a set S being uncountable means that for any list of elements s_1, s_2, ... of S, there will always be some element of S that's not on the list.

For instance, infinite sequences of bits are uncountable: for suppose that there's any list s_1, s_2, ... of infinite sequences of zeroes and ones. Let x be a sequence that has 0 on i-th position if i-th sequence on the list has 1 on the i-th position, and 1 otherwise. Then x is not on the list: for suppose x would be on the list as some s_n. Then by definition, x has 0 on n-th position if s_n has 1 on n-th position, and 1 otherwise, but s_n is x, a conradiction.

For example, if you consider a list:

1: 01011001010100...
2: 01110001001001...
3: 11010110100110...
4: 10010110101010...

and further elements, then x would start with 1010...

Please don't think I'm trivializing your point. I agree that it's deep and thought provoking.

Osth you appear to have been hellbanned, you should ask for this to be fixed. I see nothing meriting it in your comments.
There are a few differing definitions of data and information but in general it goes like this:

Data is a collection of facts.

Information is data after context or analysis is applied.

A database of phone records is data, a report on the people a target has called is information.
During the public debate around the FRA law, opponents speculated that the law intention was never to catch terrorist. Rather, the law was to fill a gap in "goods" to use for trade with the international spying community, which previous was provided by radio surveillance directed at Russia.

If that theory was true, then the current actions of Sweden makes perfectly sense.
Everyone has already answered with what a countable set is, so I would just add that the answer to your second question is uncountable sets are always infinite in size. Any extremely large set would be finite and so countable.
In my humble opinion, I consider it to be a bigger story than Vim 7.4a being ready for beta testing.
My friend with flight anxiety actually got it from researching airplane safety. While they did learn about probabilities n'all, they also learned about way too many details, after which every single sound seems like the oscillating electron pump failure on Molvania flight 52317 where nobody survived the spontaneous atmosphere exit. It's not exactly rational, it's your silly brain suddenly deciding the specific probability of gruesome death went from epsilon to 99%, and anxiety going through the roof.

Solution: sleeping pills, apparently, or generally anti-anxiety and good contact with flight staff (thus ability to find "safe feeling" seats). In the specific case.
Thanks for the book mention. It's now sitting in my Amazon cart.
Different missions? Both have exactly the same mission - keep the current elite in power at any cost.
we have basically outsourced the job of drawing conclusions from opinionated people to reporters

Yes, and this is economically efficient. Of course they get all sorts of things wrong at the outset - the fact that this is annoying is a reflection of how much we rely on them. But the fact is that in most cases we don't especially need to know these things immediately; I'm curious about this crash, of course, but it doesn't affect me directly and there's nothing I can do about it. It's actually better that I didn't check the news until a bit later in the day when some time had gone by and the details had firmed up - I'm a little behind the curve, but I've saved 2 hours of pointless and probably poorly-founded speculation. If it wasn't for the fact that my wife watches more TV than I do I'd probably go days at a time without checking, and just catch up Saturdays when the Economist arrives.

I understand being a news junkie - because I am one. But it's an unhealthy habit that rarely yields enough advantage to justify the time involved. I'll check out your startup but really, I suspect it would just be an endless time sink for me. I already find this a big problem with text-based news.

EDIT: I meant to say internet-based news.

To answer the reply below, I guess my question is 'what benefit is there to me in following multiple reports as they break? To be good at it requires doing it on a regular basis, but the economic benefit is questionable. I think it's a great idea, and if it can build up a sufficient community then it has the potential to function as a better news bureau than existing sources. The hurdle to climb is that the number of people who will be both skilled at analyzing breaking news events and have the time to put in regularly will be fairly small, and every time there's a major event the interested local population that joins in will consist largely of -first timers, whose contributions will amount to (Shannon) noise.

I mention a local event, because I see that while we're worried about this because many HNers are in the Bay Area, over on the East Coast near Maine a train carrying oil derailed and exploded in the middle of a small town, flattening the town center and with 60-100 people missing. So a plane crash with only two fatalities doesn't seem very important from a different perspective.

I've had CNN on for a while and it's amazing how little information they are giving. Until I came here i didn't know if there were 2 dead or 200 dead. It's almost as if they are so concerned with being wrong about anything that they can't offer any sort of initial report, rumor, or conjecture.

I wish there was a decent set of tools for using regexes as list generators. I've seen a few tools and libraries, but they make weird assumptions and never quite do what I want.

Here's what I'd like:

- Infinite repetition operators are automatically rewritten as constrained repetition operators based on some global parameters e.g. * = {0,2}, + = {1,2}, {n,} = {n,n+3} or some such

- Character classes can be rewritten as well so . can be kept as "just printable ASCII codes" instead of veering off into all sorts of unicode bits

- Exhaustive list generation, generate every possible match using the rules above. Too many tools seem to go about some sort of random walk against the FSM and you never know what you're going to end up with

- Decent coverage of operators. Too many have weird limits like no {,} operator or no [] character classes.

Getting exhaustive lists like this can be a better way of showing what a regex will match than trying a bunch of examples. A Perl and/or Python library would be extra awesome.
Probably a simple logical fallacy. The dead aren't going to walk off a plane, so if you look around yourself after evacuating a plane and don't see anyone dead you might say that everyone seemed to be ok.

I'd have thought[1] (post reentry) initial parachutes/streamers, either released or retracted, with a retro-engine landing.

Could be that the weight savings in fuel aren't enough for that choice, or that there are other good reasons not to (added complexity, potential non-reusable components)

I disagree.

Certainly having a social following / media connections pre-launch (either for the idea or personally) can help greatly, I believe that it can be completely overcome by hard work and a really good product.

Calling it a popularity contest trivializes the effort that many people put into their campaigns.

Source: I launched a Kickstarter campaign that did ~$500k on a $20k goal this year. No media connections, no social following pre-launch.
It is well proven that Aleph one, which is the infinity of the real numbers, is undeniably bigger than the infinity of the natural numbers.

The clause "Aleph one, which is the infinity of the real numbers", is known as the continuum hypothesis, and has a fascinating background in itself.

First, the existence of Aleph one in axiomatic Zermelo-Fraenkel set theory depends (surprisingly) on the Axiom of Choice. If you reject AC, we can't show that there exists a unique Aleph one.

It gets weirder. If you accept ZFC (ZF set theory, plus the Axiom of Choice), we can prove that both Aleph one and the cardinality of the reals are greater than Aleph nought. However, Gödel proved in 1940 that Aleph one cannot be proven to be equal to the cardinality of the reals, given ZFC. In fact, none of the main ZFC axioms constrain the continuum hypothesis--there are some proposed axioms, like constructability, which imply CH, but nobody is really sure whether we should accept them.

This is very much a philosophical problem in mathematics: having proven we cannot decide on the basis of the axioms we widely accept, it's now up to us to choose which branch (or both) of mathematics is more useful or epistemologically satisfying--or find other axioms we can agree on that in turn constrain CH.

[edit] derp, just read to the bottom, and it's comment #1. Right then, carry on. :)
Those of us with the technical understanding to be concerned about security should already be using third-party tools like 1Password, LastPass, etc. I doubt there'll be a massive out flux of those who use those tools to iCloud keychain.

What iCloud keychain does bring is much better security for the other 99%, encouraging them not to re-use the same password across all their sites and to choose good passwords by default. When I see how difficult it has been to get other members of my family to adopt 3rd party password management systems I can only see that as a good thing.
By "JavaScript generation", this project appears to mean ClojureScript. Weird way of putting it. That's like shipping a C compiler and billing the feature as, "Assembly code generation".

You can get the ClojureScript runtime much smaller by turning on the Closure (with an S) compiler's optimizations. Still gonna be bigger than vanilla JS, but for that you get a much more expressive language and the ability to share client and server side code.

The debate over whether/when it's appropriate to use CLJS is surely not over. Before judging it as impractical, note that a new iOS weather app written in ClojureScript is getting rave reviews: http://keminglabs.com/blog/angular-cljs-weather-app/
TBH, if this was only interesting because some geeks might have their travel disrupted, it would indeed be off topic.

Traffic jams and CalTrain disruptions would certainly be.
A thousand times yes. Set your expectations accordingly and then go for it. I've compared laying out a high speed board to the equivalent of pulling out the Linux scheduler, rewriting it to use an atomic clock for systick and re-inserting it into the kernel such that every distro still works :-) That said, the really cool thing about "System on Chip" or SOC devices (like the one in Raspberry Pi or on the BeagleBone) are that most of the hairy high speed stuff is inside the chip and you're only worried about the low speed external stuff. That is much more doable.

I started laying out a "small" Zyng board and running though the DDR3 timing calculations for each signal line was insanely complex. I was like "seriously?" It explained board layouts where the memory traces are all made the exact same length even if that wastes board space.

That said, if you're interested in pursuing this and are willing to spend some time taking online training and building a number of exemplar circuits to test out your understanding.

Start at 10Mhz and work your way forward to 200Mhz.
it is interesting how emergency this emergency situation is - the people are being let out only through one door, and they aren't additionally channeled through business class door even though business class people have obviously already left, and there seems to be no damage to the plane blocking the economy to business class passageway. The emergency exit atop the wing is also not activated. I mean it seems that it isn't that big of an emergency from POV of the people inside the plane.
so? did something change since April 2011 that you suddenly post this?
Ask HN: I want to program epaper
Hi,

I'm looking for some cheap epaper that is easily programmable (via usb if possible). Does anyone have a suggestion ?
Basically, the United flight holds short of runway 28 as he may need a little more time (this is the United flight CNN showed sitting there, probably).

The ATC controller knows something has happened because the first time we hear from 214 heavy, the controller tells the pilot emergency vehicles are on the way.

Then some captains on final announce they're going around and some ask for redirect (one clearly to San Jose). The controller then tells some flights on final to go around.

Finally he's directing rescue units to cross all runways where normally they'd hold at each runway to be directed.
We do whatever we're used to.

I fly gliders, where it's fairly common to wear parachutes in flight to guard against structural failure or mid-air collision.

We're told that when we're done flying, we should always exit the glider first, then remove the parachute. Some people will unbuckle the parachute first, then step out. Some of these people have gone on to bail out in flight, and they undo their seat belts, unbuckle their parachute, and then bail out of the plane without it.
You don't change behaviour like that once it's been introduced. That will just break existing code in very subtle ways.

There's plenty of code out there that rely on default values being assigned a mutable value and changing it -- even in a major point release -- would be far worse off. Python's been around for 20 years; it's too late to make a change like that.

It IS a "wart" in that you need to be aware of it to know that it's an issue, but once you are, it is an obvious thing to spot.
FWIW, I was in the airport waiting for my flight to SFO, and I took out my laptop and found this on HN. The counter staff only informed passengers of the news one hour after the HN post.
US rendition map: what it means, and how to use it
Free flight was supposed to have happened already. But there are obstacles.

As for ATCs if you do not make use of a skill frequently, you atrophy. When you are suddenly thrown in the middle of an emergency, you perform badly. We can't have "mall cops" watching computers doing air traffic control.

People do not like automation that much either. Consider the fact that underground trains have drivers even though technically they are not needed.

And then there are the technical aspects...

So I do not think that this particular crash would bring much new to the table.
Top Apps For The 1%
The National Security Agency is a cryptolgic agency tasked with gathering foreign signals intelligence and providing information assurance services to the United States Government (especially the military).

The Ministry for State Security was a secret police / intelligence service tasked with a broad range of powers focused in keeping the party strong as evidenced by their motto "Schild und Schwert der Partei" (Sword and shield of the Party). They were primarily responsible for internal surveillance of people that were deemed enemies of the party and the personal protection of party leaders.

It's pretty clear that a catch all secret police / security intelligence agency is different to a foreign signals intelligence agency.

Product posts are always fun here. This "no" strategy is awesome, but only works if you've got support from the C suite. If not, you have sales goals and whoever runs sales will always convince people that they can get more sales with "feature X", which is of course almost always just deflecting responsibility (and is sometimes true for large features that open up new markets).
Almost as they they're trying to report rather than spread "rumor, or conjecture"? If that's the case they deserve applause; it'd be nice to see news agencies back on the reporting track, analysing and filtering before going on-air.

I read the page at 1920x1200 and I didn't even notice the footer until I started reading the comments in this thread. Once I saw it, it did feel odd though.

I'd recommend you start by designing shields and/or capes.

Designing a complete system from scratch has three components, the system design, verification of the design, and then bring-up. Its very frustrating there in the middle. If you want to practice take a built system, and the data sheets for the parts, and write an operating system for it. A lot of chicken/egg problems. Things like "Ok see if the HW bootloader is working by loading a loop which toggles this line which I can watch using an oscilloscope." Real, starting from nothing into something stuff.

Designing shields (Arduino) and capes (BeagleBone) gives you a "known" working system so that you can prototype various peripherals you want in the final system. This is what manufacturer evaluation boards are actually for. They have the ability to be configured into all of the supported modes so that you can try them out prior to building them. A number of systems just lift the schematic from the Evaluation board, delete the parts they don't want, add the parts they do, and voila system "design."

Staying below 20mhz is a good idea until you get a handle on what happens to signals as they travel across a circuit board. Working with LVDS (low voltage differential signalling) lines only makes sense when you see what a 50mhz line looks like 4" from the processor on an unterminated 3 mil trace. :-)

Also if you make useful shields/capes and re-sell them then you can earn some money to buy the tools to make the more complex systems. You will also discover that a 500Mhz oscilloscope that is 15 years old is nearly as expensive as a 500Mhz oscillocope that is new because well if it works and is calibrated, then it works. Kind of like machine tools, they have intrinsic value.
A lot of plane crash deaths happen after the crash - burning fuel can spread quickly and kill or incapacitate people inside. Every second counts. Even if you already have your bag in hand, you're leaving less room for others in the aisle.
Can you give me a use case for this? It is not very hard to do, given that random matches are already being generated, but I'm skeptical of its usefulness.

It is certainly well motivated.

I wanted to highlight the difficulty the Easter Germans face when considering that 3% of the their population was actively spying on the other portion. Not to mention the large number of people who had something nasty to say about their neighbor.
I was surprised by the Khinchin–Lévy constant. For almost any real number, if you take the sequence of convergents of its continued fraction, $\frac{p_1}{q_1}$, $\frac{p_2}{q_2}$, ..., this is true:

\[\lim_{n \to \infty}{q_n}^{1/n}=e^{\pi^2/(12\ln2)}\]

The number on the right is called the Khinchin–Lévy constant.

you grab your bag if it was readily accessible?

Wrong. In order to be certified airworthy, you have to be able to evacuate an airliner in 90 seconds, in the dark, with some of the emergency exits blocked. Here's an A380 doing it: http://www.youtube.com/watch?v=4TAkAcQOnQY

If everyone stops to grab their bag, it can take ten times as long. If the plane is on fire, then people die.
Just Google these words and add the word 'summer' to get some ideas. Here's what I came up with:

Bruising: More children play outside in the summer → more bruises → more parents/children(?) Googling for it.
Brown spots: Might be referring to brown spots in someone's lawn due to the weather? Or summer freckles?
