Ideas as a currency - pt.1
Some people prefer an open office environment. I know I do. I just from a job where our whole team sat in one room to a place where we all have our own offices. I kind of hate it. It's not that I'm any more/less productive, it's that all kinds of other conversations just don't happen.

"Did you see that article on hacker news about X?"
"Hey, what do you guys think about this design?"

All of that stuff can happen, but you have to force it to happen by leaving your office. It doesn't happen as naturally. You might think of these as distractions, but I think these are the type of interactions that make people more invested and passionate.

Also, I get WAY more distracted when I have my own office. I find it really easy to just sit and browse the Internet instead of working. When my peers are around me it's harder to get lost on the Internet because I don't want to look like a slacker.

To each their own. I can understand the advantages and disadvantages of both.
Ask HN: Submitted link was instantly dead.  Reason?
The item in question was http://news.ycombinator.com/item?id=3994609
The reason is obvious to me. In fact it is so obvious now that I am kicking myself for not finding a way to make money out of it.

It is related to the reasoning proferred by the Atlantic, but it is not exactly it. It is true that Zynga and facebook are very related. And for that reason, it seems to me that a lot of Zynga shareholders were holding Zynga shares not because they want to own Zynga, but because they want to own Facebook and there was no way to buy Facebook on the public markets until today.

So a lot of Zynga shareholders were merely holding Zynga as a proxy for Facebook. Once Facebook was offered all those people decided to sell Zynga to buy Facebook. And Zynga tanked accordingly.

Now of course you will ask, why did Facebook seem to tank at the same time. If my theory about Zynga was true would that not mean that Facebook should go up as Zynga tanks. Yes, if all other things are equal. But in this case they were not. Facebook went down for a different reason. The reason Facebook went down is the usual immediate post IPO sell-off when a bunch of people that got into the IPO sell their shares immediately to make some quick profit.

So yeah, I wish I had thought about that yesterday.

Facebook a HFT's dream in the final 15 minutes of trading
For reference, see this chart of the final 15 minutes of trading.

http://imgur.com/c61tU

Before this, it was clear that buy demand was eroding in the final hour of trading in Facebook and sell demand was picking up.

But, JP Morgan and Morgan Stanley have a 2.4b over-allotment option with this IPO which gives the them the ability to continue to sell shares at the offering price. That can counter effect sell orders which drive down the price of the stock - resulting in price stabilization. You can see in the chart that those sell orders were definitely buffered - right at the $38 level - for a good 5 minutes

And, the bid/ask between those orders maintained a 38.00/38.02 during that timespan - almost a full 5 minutes. With a pool of 2.4b to "steal?" from - the HFTs must have absolutely cleaned up during that timeframe.

Why? The underwriters had no choice but to save face and prevent the IPO from dropping below $38. And they had a 2.4b option to draw on. A practically unlimited buyer vs. a big computer that is strategically selling? Wow!

Someone out there in the HFT world is having a nice martini this evening, while everyone else is on this deal is face palming.
What I've heard (from a friend at MS) is that the initial delay was due to the underwriters convincing larger funds not to just dump all their shares at the open ...

Everyone knows this, the problem is that very few devs straddle the iOS/Android fence, and therefore are more familiar with one platform than the other. While most devs might know that conventions are supposed to be different, few have a deeper understanding of what is necessary for actually implementing each. Someone who truly understands both platforms and treats them accordingly is quite rare.
"A couple of years ago, I realized that I was not the material of which great artists are made and that I was rather glad I wasn't. And since then I have been happier simply to do the work and to take the reward at the end of every day that is given for a day of honest work." - John Steinbeck in August 1933
Eventually, when Facebook reaches their sunset, the information will be sold off. It will be used in direct marketing by other companies. This is an opinion not fact.
This code sample no longer works:

Printer *printer = [[Printer alloc] init];
if (printer)
{
[printer print:hello inExchangeForUSDollars:2.00];
[printer release];
}

Because objectivist ideals require that there be no regulation of the free market, I have opened the maximum number of allowable handles to the printer, thereby exhausting the supply (which I now horde). All printer access must now be routed through me. So please use the following code snippet instead, which is the only mechanism by which you can access the printer:

PrinterMonopoly *printer = [[PrinterMonopoly alloc] init];
if (printer)
{
[printer print:hello inExchangeForUSDollars:99.00];
[printer release];
}

Should you attempt to build a printer replacement, I will deny you and your customers access to every other system resource I have similarly horded (you'll probably need a file handle to open the file you want to print, right?) and I will undercut your pricing thereby forcing your bankruptcy after which prices will resume at previous extortionate levels.
> If time is wasted driving, is building more efficient cars really the solution?

To first approximation, humans have a fixed amount of daily attention span.[1] Automated driving will effectively increase the workforce by ~5%. The base rate of "maintenance attention" is already supplied, so much of the 5% will go to the margins, increasing the rate of progress. Since progress compounds exponentially over time, this is huge.

I think it depends on the project. With any sufficient amount of talent behind something this ambitious, the $200k they raised on Kickstarter will go quite fast...on one hand, they should take the VC money while they are "hot" - but on the other, if they could ride out their funds they would probably have more leverage with a stable-ish product in place.

Alias does not change the root dir, according to Nginx documentation. This was what made us believe that through eventual exploit, it could be possible to reach the active root dir through a completely different path as set per alias. In addition to that, having an erroneous document root communicated to CGI components such as PHP or mod_perl can lead to problems. We're still following Nginx development, in case things evolve.

What a bunch of gossipy hens.
Today was a Friday.

Markets usually sell off on the last day of the week before heading into the weekend; i.e. traders don't (usually) like holding positions for two days more than they have to.

I think it's important to factor this into any discussion of Facebook's trading debut.

I personally would be waiting to see who things fair next week/monday.

[addendum] I'm quite surprised the IPO was set for a Friday because of this.
I'm not sure what I was expecting to see. Maybe a board with the price on it? That was a cool glimpse but pretty surreal
"While it is possible to hide or obfuscate calls to APIs that are not included in the SDK, this is still a violation of customer expectations and Store policy."

Wait, does the platform not include a sandbox to make sure this doesn't happen? What "security" can you expect to get out of such a platform?
It does change things when you know the people personally in terms of what you might say about the company they work for.

But what the "HN mob" is evaluating is what Facebook is actually doing, not each and every employee of the company as a person.

Ultimately, it's more important what Facebook's users think of the company, and what hackers who understand the technology that Facebook uses think of what they are doing, not what Facebook's business partners think of Facebook's employees and management.

(This is my opinion not fact.)
It'd have to be a very strong shell to actually give you buoyancy above simply not having anything. Carbon fibre is strong in tension, while a material which can support a vacuum must be strong in compression. The weight of any shell is going to be much greater than the buoyancy you'd gain.

Ask HN: How do I know where my mobile downloads are coming from?
Hi everyone,

Last month, my company launched its first mobile app. The team has been promoting the app all over the place (FB, Twitter, forums, email, Ads, PR, etc). As a result, we have grown to a few thousand users, which is awesome.

The problem is that we have no idea where our users are coming from. We don't know what our most effective marketing channels are. We don't know which marketing campaigns are most effective in bringing users.

How do you deal with this problem? Please list the pros and cons.

Thanks!

Lucene is the one-stop solution for what you want, but it does require some setup on your end. If that's overblown, what you should compare would be either Levenshtein distance or something like Metaphone or a stemming algorithm. All have implementations in many languages, and are easily integrated into whatever you're doing.

>"So a lot of Zynga shareholders were merely holding Zynga as a proxy for Facebook. Once Facebook was offered all those people decided to sell Zynga to buy Facebook. And Zynga tanked accordingly"

If people were holding ZNGA as a proxy for FB, with the intention to dump the shares for FB when it went public, then these people should have known that others would be doing the same. Thus, they should have started earlier. I think this theory explains the flash crash, but not the bigger picture.

>" The reason Facebook went down is the usual immediate post IPO sell-off when a bunch of people that got into the IPO sell their shares immediately to make some quick profit."

A stock transaction is a two-way street. There is a buyer on the other end of the deal, you don't sell shares into a vacuum. So, selling the shares doesn't drive down price, lack of demand does.
Did you go to a university with a business school? There's no crossover. One's an undergraduate college and the other's a postgraduate college. Absolutely nothing in common.
This is happening. I personally know of 3 Kickstarter -> VC-backed startups, and I'm sure it's more widespread than that.

Kickstarter serves projects that are on a continuum from "pure" art (uncommercializable) to pre-sales (already commercial), so a transition to a full-fledged commercial endeavor makes a lot of sense for many many projects.

There will still be a lot of amazing Olympic amateur projects, I hope/expect!
For me, P vs NP is a very clever bit of theory, and proofs of NP-completeness are actually kind of fun, but the more interesting question that it skirts is this: How do we talk about the speed of different algorithms? That's a much bigger topic, but usually a lot more relevant. If you're someone with code who's in a hurry, you benchmark as realistically as you can manage and hope you didn't flub the implementation, and that your data collection was statistically okay. If you're Donald Knuth, you define a simplified but somewhat realistic processor model and derive expressions for how much time your algorithm takes, and there's your answer. This is nice, but a lot of work, and it becomes positively nightmarish if you want accuracy on modern processors. If you're an Intro to Algorithms class, you look at the asymptotic complexity -- mergesort is O(n lg n), the (NP-complete) 3SAT problem is O(2^(n^k)) for some constant k, and so on. This gives good intuition a lot of the time, but not always. Insertion sort typically beats mergesort for small n, there are a lot of 3SAT problems that can be solved very easily, caches are all the time doing crazy stuff, and in general the world is complicated. We're interested in getting computers to solve problems in a reasonable amount of time; what are we to do?

I know this isn't exactly an answer to your question, but I really wish that people had said more about this in college, and I wanted to talk about it.
Oh, I see. People just randomly leave. Of course! No need to look further, nothing that could have been done.

That's a big load off my mind. Thanks for pointing this out :)

I think we can all agree that Zuckerburg is indeed a Hacker (in the HN context). He's been hacking since he was a kid, and he built facebook (duh). When he was at StartUp School a few years back - he was clearly in his element.

If we are bashing fb for using personal info to sell ads - the same principal basically applies to any major social site in the world.

Hate him or love him - fb has been a huge boon for the everyday people, tech startups, and hackers; and along the way has made Zuck and many others massively wealthy. Don't hate.
As I understand it, that's their ISP cutting off the tidal wave of traffic at the network edge to prevent it disrupting the core, like they do in the event of a DDOS.

Social honeypot. Perfect.

HN itself is a sort of social honeypot. But just look at what FB does with the information they collect.

They simply have no sense of restraint. And it all starts with Zuckerberg and his attitude.
This isn't a "possibility", it's the duty of the underwriter.

> it makes it possible for a family which can't quite make the up-front cost for a home to still buy a home

But does it actually have that effect? Once everyone is using mortgages, everyone is back in the same place as before mortgages.

To put it more concretely: before mortgages, houses might average around $100K because the average person simply cannot afford any higher. Once mortgages arrive, houses might spike to $300K, because your average person can afford that mortgage. So while the example family might not have been able to afford the $100K house because they had $80K, a mortgage won't help because now houses are around $300K.

So I don't quite grasp how this would affect rents. That seems to be an orthogonal issue.
That is a different project, different set of people.
I really think you're reading too much into it.

It's not a 'poetic hack', it's just neat.
Couldn't agree more. Whats the difference between advertising your site or advertising your "Win a free iPad" referral link? Go tweet anything with the word "iPad" in it then reread this article and see how you feel.
> And I have nothing to do with this app by the way. I just love it

I'm not sure I buy that. The only thing you have posted on HN is a link to this site, which you've posted three times. Based on http://news.ycombinator.com/item?id=3990122, you have second sockpuppet as well.
A good question. Certainly, without preparation, I would have received an above average score. IIRC, CWRU required a 33 on the ACT for the better of two merit-based scholarships. I got a 34 the 3rd time I took the test. I think the difference between the two scholarship levels was around $18K. Given that I think my studying was worth at least a point, I can argue that my time was rewarded at at least $180/hour.

[To answer what I think is an obvious question, I doubt the overall utility of my hundred hours spent studying. However, it wasn't like CWRU was going to give me the same scholarship for having done something more useful instead.]

If users don't like Twitter's monetization strategy, they can use an some other microblog or social networking service.

It's kind of like saying "I don't like paying for coffee, so it's OK for me to break into Starbucks at night and steal some." It's not, because the terms of the transaction aren't that. They're "if you give me money, I will give you coffee" and you can agree and trade money for coffee or disagree in entirety and go without the coffee. You aren't allowed to walk in, take the coffee, and quip "I'm altering the deal; pray I don't alter it any further."
Be careful not to give him credibility just because he's an expert.

While we should take notice because he has a track record of knowing what he's talking about, we should evaluate his claims on its own, regardless of who makes the claim.

Is it true that VCs no longer invests in the hard sciences? I don't think so. There's VCs that invest in cleantech and biotech.

Is it true that VCs like quick returns and will increase investments in social media? Probably. In addition, they can only invest in what entrepreneurs are building.
Ask HN: Bell Canada Galaxy S II has International Restriction on new customers
Hello everyone,

I'm currently in Canada and I would like to bring my Galaxy S II (in 3-year contract with Bell Canada) with me to China. I had an online chat with a sales rep about what I need to do to have it working in China without paying for roaming. She told me that I need to unlock my phone for $75 in order to get rid of the International restrictions that comes with any new customer's plan. I thought a phone has to be unlocked in order to take foreign sim cards. However, from my understanding of the sales rep's explanation, I CAN use my phone with a foreign SIM card with no problem, but I need to pay roaming afterwards. So what do I have to actually unlock in order to have my phone working in China (with local a sim card) without having to pay roaming?

Thanks.
I've been using a sort of ghetto hack, so I'm not sure if you want to copy me.

Days after the story broke shareholders had an opportunity to replace Dimon as the chairman and reducing his comp package -- leaving him with the CEO title. They overwhelming voted not to.

It's a big fraction, but it's just one quarters profits. It's not the destabalizing, company-breaking amount of money some people make it out to be.

JPMorgan has over a trillion dollars in assets on its books. The chicken-little nature of this has been a little silly I think.
No doubt Dan is pissed, but holding back his anger because that's his nature.

The Talk Show was started by John and Dan in 2007. The website (thetalkshow.net) is registered to Dan and was most likely coded by him as well. Dan has just as much invested into The Talk Show as Gruber. It would've been much classier to leave 5by5 and start an entire new show.

The Talk Show is Dan and John. Period.
