> I'm not arguing in the first place. I'm just describing the things as I undestand them. I may be wrong, but that's why I'm describing them: so that other's can explain them to me if they feel like doing it.

It's fine to post-rationalize it that way but your initial comment left very little room for that interpretation. Questions generally work better than assertions for addressing curiosity.

> I don't see this as communication. To me, it feels more like begging for attention. I don't feel like this is something I'd like to be doing (or at least feel like I'm doing).

Not really sure what to tell you. You're also not seeing all the direct messages that pass between people, responding to certain things privately, or the many @replies that aren't parsed into the public web interface due to flakey clients. But whatever — you're finding ways to reassure your preconceptions and that's totally your privilege. In the end, though, "not my cup of tea" is a very different sentiment from "I fail to see any other legitimate use of it."

What you call vacuous I call personality. The people who work on interesting things are worth getting to know personally. I've enjoyed meatspace drinks and, again, entire paid gigs through getting to know people this way. A good friend who was fucked in unemployment land scored an amazing gig through just being fun and personable on Twitter. Thus same friend managed to introduce me to some people I really admire through the same means.

So if you want to view Twitter through this boring-ass lens where you have no curiosity about your fellow humans, well, I guess it's not surprising you're not going to get much value from it. Like much of life, it's what you make of it.

It is not realistic to expect all users to continually make backups of all their Google services.

It is however realistic for Google to solve this by putting a violating account in a "read-only" mode, where you are able to export all you data and not do anything else.
Translation. Do what FourSquare should be doing, just don't suck at it.
My guess would be that the downvoters believe your comment adds nothing of substance to the discussion (though it appears to be up to positive score again).
Actually, if you seed your random number generator more than once ("re-seed"), then you're completely destroying your entropy. Which is obviously the exact opposite of what you're trying to achieve.
Somewhat off-topic, but looking at the readme of JSONKit [1] I found: "At this time, there are no plans to support ARC in JSONKit. Although tenative [sic], it is extremely unlikely that ARC will ever be supported, for many of the same reasons that Mac OS X Garbage Collection is not supported."

Which seems kind of weird, seeing as ARC is going to be the default pretty soon.

The strategy that I have used when out of the job market for a while is to consider the first few interviews as throwaways that I use to learn what he market conditions, interview fads and the like are. If I get blown away, so what; it's a learning experience. If I get an instant offer, I'll still keep on looking, until I get a good feel. (Unless it's the best job I've ever seen.) It's like dating. You shouldnt get bummed out if the first person you date isnt a fit.

EDIT: If you have a stable relationship, consider giving her the financial help that she needs to make a career change. Give up your bowling league or whatever. Consider her to be a good startup investment. Of course, consider the soundness of whatever she wants to do. If her dream is to start a used clothing store, it is probably best to be a bit hard of hearing.
Maybe I'm splitting hairs but saying something like "The top 1 percent rarely serve in the military . . ." without pointing to any data gives me an allergic reaction.

Is that true?

The closest I could find is:

"Members of the all-volunteer military are significantly more likely to come from high-income neighborhoods than from low-income neighborhoods. Only 11 percent of enlisted recruits in 2007 came from the poorest one-fifth (quintile) of neighborhoods, while 25 percent came from the wealthiest quintile."

To be fair the above data is measuring the top 20% (quintile) vs 1%, but that group still earns 50% of the overall wealth in America:

Hard to believe your comment was downvoted. It's true, people like me knew more about her "trouble-making antics" than her music. That's wrong. She deserves better.

I've heard that before and I'm genuinely curious. Why does it matter?
Magic Trackpad makes it just as awesome on a desktop machine.
This brings up a good point. The controls are even set swapped compared to gamepads, so using the wrong hand isn't comfortable. Old computer games did use the pc arrows of course. But now since this is a remake of the classic, it should at least be hand aware :)
Google [briefly] suspends Limor Fried's ("Ladyada") Google+ profile
Twitter's self imposed 140 char limit has limited their options in a lot of ways. Twitter should have dropped that a long time ago. Or at least not count hashtags, geotags, or urls against the 140 limit. This would've opened a lot doors to add more context to tweets.
There are many true facts that are not important or relevant to the subject at hand. This strikes me as semantic quibbling, and slightly deceptive in that the term "democracy" is used for more than just direct democracy. That definition completely ignores the idea of a representative democracy. But I'm jot sure it really matters that much to the bigger picture which is more painstakingly accurate.
Yeah, _access is ownership_, after all.
History doesn’t lie: There will never be a perfect social network
That depends greatly on when in the history of the Universe the light was emitted. The scale factor varies over time. What you probably meant though was "How long did the light that we're seeing from this particular quasar take to get here?" That we can figure out.

When you get a problem like this one, the quickest way to get an approximate answer is by interpolating from the following rule of thumb: If we see light today that we know has been in transit since the start of the Universe (15.3 billion years ago), the point it was emitted from is now 46 billion light years away from Earth. If you just assume that the impact of the Hubble expansion is more-or-less proportional to the current distance of the object in question, we can just linearly interpolate between the observed Universe-scale answer and the intuitive Newtonian answer that applies on normal scales.

Newtonian answer: 12 billion years

Universe-scale answer: 12 Glyr * (15.3 Gyr) / (46 Glyr) = 4 billion years

Final approximation: 4 Gyr * (12/46) + 12 Gyr * (1 - 12/46) = 9.9 billion years
Why? There is some sort of an assumption that a romantic relationship is something desirable by default, and someone's lack of interest is somehow "sad".

I agree that sometimes the reasons for staying out of the relationships business may be sad - or, more precisely, constitute sad stories. But assuming that someone can't achieve happiness in life without pursuing a relationship seems presumptuous, especially when faced with someone who clearly defines their objectives and needs differently.
kinda does...
You know, I actually thought about mentioning that it wasn't quite exactly the same, but decided against because I really do think that it's still quicksort. Is it identical? No, you're right, it's not. But it still is an expression of the same algorithm.

Modifying the array in place is a inherently imperative technique, and while you /could/ do something like that in Haskell using, say, Data.Array.ST, you would loose the expressiveness of programming functionally and be programming imperatively just for the heck of it.

Trying to solve a problem in a functional language exactly the same as in an imperative one is foolish. They're different paradigms with different strengths and weaknesses, and if you try to map concepts 100% from one to another, it will often end in tears.
Interesting, but several of the questions I posed remain, some of I suspect which will explain the significant differences between your measurements and theirs. Except for one: NXJson is exponentially slower at reading for you than they claim it is for them, which may be hard to explain away...
Do you know any good resources to study this sort of thing from? (any summer programs?) I am a young developer and have been meaning to learn this sort of thing for a while.

Can't say I've thought of it before now, but it makes perfect sense.

My parents' home is a turn of the century bungalow in South Florida, and has survived every hurricane since with zero structural damage (there is no evidence of repair). To make that feat even more interesting, their house is located on a corner lot at an intersection of a split roadway, with a central canal, that results in about 85 yards of open ground to the east, which is the worst imaginable configuration for hurricane winds on the north side of an Atlantic storm (the worst winds).

So, what's so special about their house? It's elevated about 18" off the ground. Around the perimeter of the home (which is almost a perfect square, there is lattice work covering the openings at the base of the structure. After the first hurricane of the 2004 season, we noticed that the lattice work on the east-facing side of the house had all been ripped from it's (screwed, not nailed) mounts and pushed 10-15 feet back under the house where it laid down and allowed the air to pass through.

I stayed at the house with my parents during all the storms of the 2004 season (three total), and what I experienced was remarkable. Rather than stand bluntly against the winds, the house allowed the pressure to "breath" through it. That's how it had survived all these years. Well, that and it's made of heart pine and lumber that was cut prior to the advent of "dimensional lumber" :)

This design modification of this HUMVEE works on a similar principle. Got a pressure wave problem? Don't try to stop it, just give it somewhere to go. That's the great thing about air pressure, it seeks the path of least resistance.
A democracy is mob rule where minorities can't win unless they persuade the majority. A republic (we're a democratic republic) elects a moral governing body (congress) to make informed moral decisions. Only part f their decisions are based on the whims of the public. In theory, the rest should be based on expert witnesses from all sides of any issue (hence why people testify in congress). This allows for immoral majorities to be shut down and vice versa.
It's not a "fact" since, as your link acknowledges, it's nothing more than a pedantic and rather archaic take on the word "democracy", as if only the Ancient Greek view of the world matters. Here's a modern definition http://www.merriam-webster.com/dictionary/democracy

> Not all technology is created equal: there is a difference between Pong and the Concorde

Yes, Pong was simply a clever design making use of existing technology that made shirtloads of money for a bunch of people and spawned entire industries. Whereas Concorde - a "real technological development" - was a giant money pit fed from government slush funds for decades, punctuated only by occasional lethal consequences for its passengers and bystanders. (Not to mention that it was a technological cul-de-sac.)

Remind me, which one was it they want to be investing in? Because it sure sounds like they're saying Concorde. Am I misinterpreting?
Yes, rent seeking behavior is bad, I think we can all agree on that. But it's unclear that the increased inequality in America is due to increase in successful rent seeking.

The statistics doesn't tell the whole story though. Global inequality is down. [1] Even the poorest Americans are rich by global standards. The author cites globalization as a cause for lower middle-class income in America. But globalization actually has a inequality reducing effect, at least on the global scale.

It's also unlikely that capital-gains taxes has resulted in the top 1% getting richer considering that the stock market has had negative returns over the last decade.

[1]: "We find that various measures of global inequality have declined substantially and measures of global welfare increased by somewhere between 128% and 145%." http://papers.nber.org/papers/w15433
Just curious...why exactly would you say reseeding adds bias? AFAIK, srand in Perl on Linux uses /dev/urandom, which uses at least some bits from the hardware entropy pool.

Swapped out rand() for MT in any case... :)
I know, I know. I like the idea of reCAPTCHA to crowdsource a very hard problem for the common good. I know how it works in and out.
It is awesome.

The only problem: things sound nice in theory do not always work well in practice. I ran into multiple occasions where reCAPTCHA presented me impossible to recognize scans, one extreme example is a printed texture pattern with not a single letter on it.

Your average, non-tech-savvy customers will never know how the system works. They shouldn't either, otherwise the whole idea of reCAPTCHA would have been defeated.

Judging by the volume of complaints about it on various support forums, it is really a bad idea to deploy it in production when you care even slightly about usability, user experience, or simply conversion rate.

Unless your application is a must-have.
Amsterdam, famous for bikes, has a nice bike share system. You buy a stolen bike from a crackhead for 10 euro. You ride it around until it gets stolen (maybe a week or two). Then you buy another bike for 10 euro. You never worry about leaving it anywhere because you can always get a new one for cheap. It's like a recycling program!
I think there is a development opportunity here. Certainly there are analytic questions that seem interesting. Imagine a kind of slider control that could be used to filter out who you interact with. The slider would set the popularity threshold. You may prefer your account to interact with accounts that have roughly the same number of followers as yours, with roughly the same number of followers and the same karma.

In this system, following someone is no longer a binary proposition: you follow someone at a given threshold. If your threshold is set below the number of followers of the account, you don't see their tweets, and they don't get to count you among their followers.
As you move the slider, your view of Twitter changes to match the threshold: accounts you may have followed at the higher threshold drop off or become visible as you change settings.

Why do this? Well, if you're a new user, you may be tired of contributing to someone else's power-law distribution. Why should you enable the rich to get richer? Why not join a system where you can interact with other users at comparable levels? Twitter is losing the Johnny-come-lately's anyway. So there is an opportunity to encourage interactions that go beyond the discouraging power-law phenomena in which a few users have most of the followers.

As Satan said, "Better to reign in Hell, than serve in Heaven." A follower threshold feature could enable this, and it might generate interesting analytics.
He just threw out some bait, and the community swarmed like starving fish.

This is true of all "light" SO/SF posts. Nobody gets excited about answering someone's obscure apt-get question. Everyone gets excited when they can spend their boring workday telling some dude that his security consultant is fucking him. It's the same reason people read "People Magazine" instead of "Purely Functional Data Structures".

No more painful than starting a blog, a podcast, or even a GitHub account. You have to actually produce stuff to get attention in any case.
Learning C++ and getting into game development are not, unless you are particularly lucky or talented, tasks that should be accomplished concurrently. They're both hard enough on their own.
Emacs follow-mode
The backup methods are very different for each Google service. If you want daily backups of all your Google services, you need to pay for multiple external backup services and/or spend a lot of time doing it manually.

And how do you download all your Google Analytics data? This page on the Data Liberation page suggests that you export to XML, Excel or TSV. http://www.dataliberation.org/google/analytics
But to do daily backups of all the dimensions, metrics, advanced segments etc. would be very time consuming.
You could do it easier with the API, but that requires programming knowledge.

Trussi,

Here's my answer to your questions:

Are the hacker or the hustler?
Hustler but learned to code to implement my idea.

Any co-founders? If so, what's their role?
3 co-founders (including me). 1 Technical, 2 of us learned to code to help build prototype. We keep wearing developers/business analyst hats.

Do you have a built MVP? Any beta testers? Any paying customers?
Prototype should be done in next 3 weeks or so. We are building Platform for consumers so B2C model.Planning on signing up small group of users to Beta test.

If no built MVP, how much longer before it's built?
3-4 weeks

How long is your runway (in months)?
Not sure what you mean by runway. But after beta launch, we have about about 3 months more of dev work to implement all of the remaining features.
Disclaimer: I'm the author of TouchJSON - the library the authors are claiming 100x speed up over.

As pointed out by other commenters the 100x speed up claim is incorrect. I added NXJSON to Sam Soffe's iOS benchmark test app and definitely did not see a 100x speed up.

I'm _guessing_ that the JSON deserialization actually failed when testing and the 100x speed up was due to the tests bailing out early. Sam'e JSON benchmark tool while handy isn't 100% fool proof - there's no validating the output of the code to make sure it matches the expect results.

While NXJSON is faster than a lot of it's competitors it really doesn't seem to do anything interesting. It is Obj-C based (you can definitely get better performance with straight to the metal C) and gets some speed improvements via macros rather than Obj-C message dispatches.

Unfortunately the 100x claims are floating around on twitter and are repeated here on hacker news. If it's too good to be true - it probably is.
This could be asked of a number of comments, but sadly, rarely is.

I've been using Emacs for 32 years (hard to believe) and never knew about this incredible but apparently obscure feature of Emacs.

On my 27" cinema display, even using 12pt Monaco for my tired old eyes for extreme legibility, I can get 4-5 columns of 90 lines each, when editing source files or text, for an effective "screen length" of 360-450 lines. With 10pt, you can get 500+ lines "on screen" easily.

connections and users are not the same thing. Accomplishing a task with fewer resources is better, so when you say " Scalability beyond 10K users/server doesn't buy you anything", you are wrong.

Imagine if you have a giant datacenter like google, and heat and power are a serious problem. Accomplishing a task with fewer servers is a serious win.

So... when people say "Deep Understanding of Linear Algebra", is it really anything more than being comfortable with the idea that rotations, and perspective transformations, can be represented as matrices? Any 3D graphics programmers (not necessarily for games) who can highlight the main aspects of Linear Algebra that they use?
Wow, that was fast. Nice.

The truth is this: if you ever hear the phrase "re-seeding", you should reinterpret it as "warning! danger!" because if you seed a random number generator more than once, you destroy any entropy ('true' randomness) that generator otherwise might've had.

When you seed a generator, you're saying "give me a queue of uniformly random numbers. Each time I call rand(), pop one from the queue and return it."

If you re-seed, you're saying "throw that queue away; give me a different queue of uniformly random numbers".

If you do that for every rand(), then you no longer have a queue of uniformly-random numbers. You have bias.

One way to think about this is: The resulting output over time is no longer uniformly random, because it's the first random number of every queue of uniformly random numbers (every seed). And the first number of every seed != uniformly random. It wasn't designed to be.

It's both hard to understand and hard for me to explain, sorry. But if you want to know more, feel free to ask more questions and I'll do my best.

tl;dr: if you seed Mersenne Twister (or any other RNG) more than once, you'll be losing most of the benefits of the Twister (from a mathematical point of view). So don't! =)

I think it comes down to what one considers entrepeneurial. Here at HN, with the crowd heavily skewed as it is towards tech, the adwords seo marketing facebook twitter dashboard mashup is seen as more entrepeneurial than this bike sharing venture - which, arguably, falls under the same class of businesses as, say, property management.
I understand NASA's PR team wants to make these headlines appealing to general audiences, and generate pageviews, but they're making the mistake of overpromising in the headline and underdelivering in the copy.

To normal people -- i.e. Not HackerNews readers -- read reservoir and think of a resource we can tap for our curren needs, a "reserve" of water. It's not that at all. NASA's PR team isn't doing their scientists any favors. It's not some egregious sin or anything but I'd have chosen a different headline altogether. Or maybe I'm just being a nitpicky former PR guy.
