You're right, it's trading vs. investing. Didn't take a genius to buy Google or Apple 5 years ago, no highspeed tricks or anything and you've made a tidy chunk of profit.

Whether or not they're drastically modifying the value of the market is really hard to say, I don't think we know that fully. Honestly, I don't think we understand it that well yet. You can make some fairly reasonable assumptions that it doesn't cost the typical investor that much over his investing life though. I think part of those assumptions are that the high speed traders are simply trying to move faster when they acquire knowledge though, to me, that seems kind of elementary for the guys that invented all these exotic synthetic derivatives and ways to mask risk and shift it around... You couldn't tell me that they aren't trying to think up other uses for those technologies if they exist; like maybe you can measure what counter parties are doing with high performance timing and get some insight.

Fundamentally, are they leaving that few dollars on the table or are they picking them up? It may only be a few dollars but it's a big difference between paying it and taking it.
You are aware that Skype requires the Skype client, even less standards-based than Chrome, and everyone can use it?
You can use Chrome and Skype alongside your web browser of choice. Chrome is spritually like the Mozilla/XUL of old -- it's a platform for apps, not just a web browser.
Every time I look at the Reminders app, I'm like "Steve would have thrown a fit seeing this piece of junk". It's so... clunky and lacking any sense of... uh... flow?
What's a sure way of determining that the clicks are not coming from a proxy? I have to launch an online campaign. There are some many services that provide a high anonymous proxy and sometimes services like http://www.ip.cc/check-proxy-basic.php report a real ip as proxy. So how do I distinguish real clicks from fake users. During the signup, I can only collect Name and Email.
> I don't think your anger about multiple assignment is valid.

He didn't express any anger about it, he just noted that it was broken. The anger he expresses is about Chrome's insanely aggressive caching (and every web dev I know agrees with that, even IE's caching was less over-the-top than Chrome's).

I'm taking his note on multiple assignment more as a supplementary piece of evidence re. Chrome's quality control: how can you break something as basic as multiple assignments and get that pushed to a build?
Android/iOS Engineer? Join us at Everyme (YC S11)
One of the main reasons we created Everyme is because the future scares us. By default, when users sign up for Facebook or Google+, updates are shared publicly with the world. If you work on apps, you know that 80 or 90% of users just use the default provided to them. That means that a large percentage of people are sharing content with Googlebot and Facebook public search without knowing.

To verify that this is true, you can actually go to Facebook and search public posts for things like "doing 90" and you'll find thousands of people talking about how they're speeding on the freeway right now, amongst other illegal activities. If a simple search can reveal thousands of people sharing things that can make them un-hireable, can get them locked up, or have their insurance rates raised, imagine what insurance companies, governments, and other entities are doing with public data?

It's clear that profit can be derived from people sharing thing in public - or breaching consumer privacy - but it doesn't have to be that way. It is Everyme's mission to change the direction that things are headed in, with a combination of engineering, design, and principled decision-making that always puts user privacy first.

If that is a mission that appeals to you, join us to make the future a better place for everyone, not just users that are smart enough to change their privacy settings. Currently, we are hiring iOS and Android developers full-time in our brand new Mountain View, CA office. We are well-funded by great VC's and have amazing products in the pipeline.

And how would you have a laptop manufacturer who designs a super-high res display to get around this problem?
Pageviews are easy, especially on a social picture aggregator. It's not hard to imagine one person clicking on hundreds of images per day. The hard part is trying to monetize these pageviews.

It doesn't take a kick-ass team to put up a link farm and spam it out. It takes a kick-ass team to profit from it and not tank the reputation. Digg failed. Reddit is struggling. I'm not sure 9gag will do any better.
Isn't Windows RT just Windows 8 without the desktop?
Sure, but towards the end he was pretty sick, so I would assume quite a few bloopers may have escaped his attention.
They don't necessarily need to do something productive for society, but they can still 'create'. For example, my early math classes were designed around questions. When we came into the room we would break up into groups, and spend the first half of (the 90 minute) class trying to answer between 1 and 5 problems, after which their was a class discussion on the problems and any tangents they lead to, and they teacher may, or may not, point out things we missed.
The moment I saw this I wanted to say "It has begun...", but then I realized that Twitter started this trend of arbitrary censorship quite a while back, and I think it's only going to accelerate from here.
Is this infographic too long or do you like it?
This just begs the question -- how difficult is it to do a reasonable job of detecting bots before passing through the "click"? If it is really hard to do during the request processing, surely it is not hard to do before billing?

It's not really an "ocean" in the way we think of such things. In the outer solar system, ice is a rock in the same way granite is a rock. What Titan has isn't so much an ocean as an interior layer of molten ice --- just as our planet has an interior layer of molten rock.
Google Reader is missing a serious mobile component, and I'm excited by what I see with NewsBlur. Congrats on the launch!
I'm curious to see how much of that difference is actually caused by environmental factors.

Most of the continental US gets down right hot for 2-5 months out of the year. So hot that air conditioning accounts for the largest share of commercial and residential electricity usage. This is probably becoming an even bigger factor when you consider there has been a mass migration from more temperate climates of the upper Midwest to areas such as Texas, Florida and the Southwest. This migration began in the mid 20th century with the advent of reliable central air conditioning.

My question is are Americans consuming more electricity than the average German because of environmental factors or because we're really guzzling power like gasoline in the 1960s and 70s?
I can hear the voice of a suffering child, "Why can't you make the boo boo go away?" and the nurse answering, "Because farts and boobs are more important that your boo boo lol"
Yeah but "funnest" is concomitant with "think different". It intentionally conveys the idea of a company that promises to do great things without taking itself too seriously.

Maybe "resolutionary" was trying to do that too, but it just fell flat for me.
What Facebook Slowdown? King.com Shooting for IPO Sometime Next Year
Do you have a better link? The Economist talks about reduced emissions in the past 5 years saying "much of the credit" should go to natural gas. Then it cites numbers going back 15 years that would give half the credit to natural gas and half the credit to renewables. I'm curious how those numbers change if you look back only 5 years.

(There was twice as much increase in natural gas as there was increase in renewables, but renewables produce approximately 0 carbon while natural gas produces 56.25% of the carbon coal produces: http://www.naturalgas.org/environment/naturalgas.asp )
It rains?
Edit: am I misunderstanding your question?
I didn't go in to this in much detail in my article, but I'd like to follow up with my long term plan for this feature. I think that buffered responses are a special case of streaming responses (they're streaming responses with one chunk), and I'd like to make this API the underpinnings of the response system in Rails.

One of the things that I think Rack got wrong and that J2EE, Node.js, etc got right is that the response bodys should be treated as IO objects. Whether the IO object streams, buffers, gzips, etc is up to the IO object. Regardless, the API remains the same.

I hope to eventually push the concept of an IO response up to Rack itself and eliminate this code from Rails.
Streaming looks like a natural evolution to me, to gradually send JSON data back to the client etc for instance.

I don't think this is something that could be done easily as a gem (at least not without a serious dose of unstable monkey-patching).
Hey now, awk is simply lovely. It's ridiculous how popular it is to slight it these days.
Former apple ad creator criticizes new olympic ads
The problem is that individuals invest in funds whose managers chase these fads -- or who invest in broad market indexes. It's hard to find a "no hype" fund to invest in, especially when individuals have their hands tied by employer/government plans that don't offer owner-directed investments. (These 401-K and other non-defined-benefit schemes always seemed a scam to me -- in order to enjoy the tax benefits of saving for retirement, I have to invest only in the funds whose manager bought the fanciest lunch for my HR director?)
And then there are the "wet bots" - Amazon Turks and overseas humans (lowly) paid to use a regular browser and PC and manually click on stuff for whatever purpose (rig internet voting, drive fake advertising charges, steal data, skew hit counters - whatever).
Saying there is no distinction between art and math is like saying there is no distinction between art and sculptury. Yes it is a type of art, but is is a highly distinct skill set from painting.
Of course the way math is taught is about as much art as a coloring book, with a well defined key.
Intel’s 64-core champion: In-depth on Xeon Phi
I'm amazed my position is even remotely controversial here. Many people here, including yourself, are framing the debate from the perspective of their own experiences as candidates, which is a biased way to look at the perspective of an interviewer.

The fact is interviewing it tough, and is inherently a flawed process (I agree with you that ideally the interviewer could get to know the candidate's character, but an hour or a day isn't the correct timeframe to do this). Good interviewers try to find the best fit for their teams, instead of lamenting the fact that the problem can't tractably be solved perfectly.
First page in HN, for some people this is considered a PR issue :)
Says the guy with a username of the ship in the sci-fi movie Alien! (Just observing a humorous juxtaposition.)

Anyway, your point is noted. One of my favorite tweets ever was one by Amy Jane Gruber, to the effect of: Boys say “If we get a dog, I’ll clean up after it,” and men say, “If we get a Dyson, I’ll vacuum!”
"What creates wide gaps in achievement in math (and many other subjects) in minority students is lower expectations for success."

I found this sentence frustrating. It was simple-minded to an extreme, neatly finding a solution to fit all minorities.

Minorities in the middle class, e.g., may have a completely separate set of problems from minorities in poverty circumstances. Recent immigrant minorities may face a different set of circumstances from second, third, fourth, etc. generation minorities.

The author's message is essentially "try harder, think positive". Unfortunately it does not address the different nuances of being a minority.
I look forward to your follow-up on sending JSON streams back to the client! It would be a nice thing to gradually add the items to a js, client-rendered list (such as with KnockOut.js).
Facebook didn't have to sell stock to comply with regulations. They only had to file paperwork. They IPOd to get the benefits of the IPO ($$$), since they already were facing the bulk of the paperwork requirements.
Oh I do think it's the best OSX version yet, I just wasn't thrilled when they announced. There was little thrilling about it (aside from the new bugs of 10.6.0, and the dropping of PPC). The most major "features" (to me) were Finder, Time Machine and Spotlight sucking significantly less, that Quicktime X existed, and the 64b kernel.
What's the difference between "molten ice" and water? Is it still crystalline? Is it just the pressure is different, or is there actual physical differences?
P2P for more than 1-on-1 is a bandwidth concern.

http://support.google.com/plus/bin/answer.py?hl=en&answe...

In a P2P video chat setup, each client has to send its video to every other client; if there are 5 clients, and the minimum outbound is 230kb/s, the client has to be able to push 1150kb/s (9.2mbit!) upstream, which is present almost nowhere in residential broadband.

Based on the downstream requirements, it looks like Google is also doing some kind of stream multiplexing before sending the hangout to clients, which reduces the downstream requirements, as well. In a P2P situation, you wouldn't get that benefit.

Even if you go with an "elected master" setup, where the biggest-bandwidth participant is responsible for stream multiplexing and broadcast, then you're disproportionally punishing that user and potentially degrading their user experience by burning a ton of CPU on the multiplexing, and the other clients are subject to their latency to the master node.

Running this through their infrastructure makes a ton of sense without the tinfoil hats.

"The future of server programming does not have parallel access to shared memory."

What about STM in Clojure? It's technically parallel access to shared memory, but the transactional nature obviates the need for mutexes and all the crap that makes shared memory a pain in the ass.
Learning mobile: iOS or Android?
I'm interested in learning a mobile development platform and wondering whether I should learn iOS or Android. Which one has a more active market for developers now, and what's the future outlook for each? I've done a good amount of programming before, just not for mobile.

I also don't have a preference between Java and Objective-C.
The we could... quote was from the article and refers to the dear readers without presuming to know what they think - it's an exhortation.

Stock markets behave mostly irrationally in the short term (see Random Walk Down Wall Street), but that doesn't mean you shouldn't attempt to ignore the irrationality and get a little closer to the objective truth - in this case by valuing companies based on what they earn and could earn, not what someone else paid for them or might pay for them.

Depends what you're after I guess - if you are trying to make lots of money in a few days/weeks/years with borrowed money, you'd absolutely have to attempt to predict the irrationality of the market or go bust. On a long time scale with money which is not borrowed/required, you can afford to take a longer view based on profits.
Please, can we now put a reasonable nuclear reactor in space, power a VASIMIR engine (or something equally adequate), and do it with humans instead of robots? We already proved we can do it with machines and who will make first contact with alien life in becoming a really important question. We are not a race of robots.

People wonder why the general public lost interest with space exploration, but we need to look no further than all the excitement every six-wheeler is experiencing right now, as they watch their six-wheeled brothers, the daring explorers of Mars.

I am an engineer. I can comprehend and I do have the ultimate respect for the genius that allows us to land and operate robots on Mars, but that's the same genius that allowed us to land people on the Moon and, sadly, this is something we don't do anymore because it's too expensive. And we refuse to spend money on that while, at the same time, we fight unnecessary wars against the dictators we financed in the past. There is water ice on the Moon, probably a lot of it. There are minerals, abundant energy, just enough gravity to make industrial processes easy and a high grade vacuum that's the dream of every metallurgist. With these resources, we can become a true spacefaring civilization fit to meet our neighbors from the other islands floating around our sun.

We shouldn't do with robots the work of humans.
The blog is "Signal Vs Noise". There was never a promise that Signal would win.
saying that something is easy is easy. fyi these guys are already profitable and killing it money-wise. also take look at their page structure - they are not even optimizing for pageviews- you can scroll and see tons on pics on one page. 9gag is killing it by all metrics, and have some great products to intro in upcoming months.

disclaimer: I obviously dont work for 9gag, but I know the founders, since they are from the same yc batch.
I actually like that browsing is kinda slow. One of my kids can code a little bit in Python, the fact that browsing is suboptimal helps him stay focused on coding. :)

I don't think it draws 700 mA except when it's really crunching CPU cycles.

The distro name is unfortunate. They should just call it "Raspian", it's a lot less tongue-tying.
Got it. I'd like that, actually. I approximate it now, but I'm not concerned with the feeds themselves, just the new items. Hmm.
>"I'm tired of "Stocks are gambling" nonsense like this."

Definitely in agreement with you here.

>"Its not very difficult."

I assume you have a portfolio that's been killing it. Would you mind posting your results?

>"but if Apple was a company that only and always grew at %20 year over year, then "on the fundamentals" Apple should be trading at 20 times EPS."

The problem is predicting that a company the size of Apple will grow 20% y/y forever. What fundamental reason do we have to believe that? We're sort of in uncharted territory there. For all we know, Apple's decline starts next year. That's the difficulty of this.

>"puts their money into index funds."

There are sophisticated financiers who insist that index funds offer the best value in investing. The world is filled with people who think it's "easy" to get "great" returns in the stock market. The reality is that in an efficient market there are no "great" returns, only average returns. Those returns are based on a function of risk (so the expected returns are the same) and some time value of money.
Unfortunately, they have this little problem of not holding any rights to any of their content. This is of little concern now, as most of it is anonymous image macros and whatnot but, if they get big, some larger rights holders will start paying attention to them.

Tobacco and alcohol companies have lobbies that help keep MJ, LSD, and magic mushrooms illegal. I am pretty sure all three are less physically addictive and detrimental than tobacco and alcohol, but it might be a very long time before we find out definitively because research is blocked by these lobbies.

Offer HN: Let's improve your startup conversion rate.
Hey HN,

I'm currently in charge of optimizing several web properties of one of the largest bank in the EU with quite positive results. I've been doing this for the last 10 years.

I'm now looking to build a portfolio of clients in order to be able to offer conversion optimization services with a proven track record beyond my current experience (being a bank I can't share a lot of info)

If anyone is interested, I'll be more than happy to review your current landing pages, check out processes, etc. and suggest changes and improvements in order to optimize them.

The only thing I ask in return is that you actually test this changes and let me document them.

Do to time constraints I can only take a couple of projects at first.

If you guys are interested you can shoot me an email at web [at] fabiandesimone.com or the email in my profile.

Android is free to develop for, has a larger marketshare, and does not require any specific system to program on.

iOS costs money each year to develop for, requires a Mac to program on, requires your app to submit to approval for every update, and is extremely locked down and terrible.

I think I've made it clear what my answer is.

What kind of app are you planning on making? Free or paid? Game or utility?

> Partly because Philosophy is one of those fields in which thinkers can benefit from obfuscation

This isn't true in physics. Why is it true in philosophy? Do philosophers see this as a problem?

> Philosophy is one of those fields that relies on the self-motivation of its students.

So do all fields.
Seems unfair to judge Apple based on rumored specs for the "iPhone 5".
So basically, before you condemn Apple, remember all the good ads they had before? All the ads they had with a real point, showing something that was clear to the viewer?

The reason Apple is being condemned right now is because this ad isn't a Think Different ad. It isn't a Here's to the Crazy Ones. It isn't a Mac vs PC. It's not memorable, it's not unique, it's not defining a culture. It's simply an ad. That's very un-Apple.

Maybe before you defend Apple again, make sure they have a defensible position. "They had good ads in the past" is a non sequitur, and honestly if your argument is "yeah it's not good, but let's just forget about it", you might not be thinking clearly.
No, I'm pretty sure I have it right: "cabal-install" happens to be the package that contains the cabal binary. I installed that specifically because the instructions on the gitit page start with cabal and skip the Haskell installation; but the dependencies pull it all in automatically anyway. The problem is simply that it's too old, despite being the most recently packaged version on the most recent release of the distro. And the solution to that problem involves building the whole thing, which I'm not willing to do to try gitit.
My point is that we shouldn't continue to allow people to turn "I have an advantage in math" into "I'm terrible at spelling and won't bother trying to get better." My nephews illustrate that advantages don't have to become liabilities in other areas, which is how this dichotomy is presented in the OP and the article it was responding to. The scientific evidence can certainly illustrate advantages and disadvantages in different areas; getting from there to "some kids are terrible at English and the rest are terrible at math" is a huge, unwarranted leap.

I agree with everything else you have to say.
