Here is my take on curing cancer from a programmers perspective. Extract a healthy strain of DNA from the patient, insert the healthy DNA into a virus that will be targeted to attack all cells of a certain type, which will include the cancerous cells. The erroneous/ cancerous will be replaced with the healthy DNA, while healthy cells get the DNA they already had. It's kinda like reformatting a hard drive. Has anyone heard of a custom treatment like this?
Even though it will be hard to determine the optimal amount of trading per second, you have to agree that the situation now is far from normal.

One of the most important economic benefit, and function of the stock market, is to allow companies to raise capital.

High frequency trading does nothing to promote this goal.

In some sense the stock market today is more like a gambling hall.

Does the intrinsic value of a company change 29 000 times per second ? is this signal or noise ?

Trading once per day and randomizing the order of trades would work nicely I think. There was a recent very good example of this concerning Apple : When Steve Jobs died, they kept the information secret and agreed with the stock exchange to suspend trading for a day. The time for everyone to think about what it meant for the company instead of hysterically following a random trend. A big event, obviously changing the company's intrinsic value, was interpreted with a daily period. Everything I read about high frequency trading indicates that it is mainly noise.

I mean, stock exchanges close at night and during week ends. There are 48 hours without quotations. How does one concile that with nano-second trading.
That's the theory. In practice we know that's not necessarily true. e.g. stop-loss order and the stock gaps down. Did the stop-loss order execute? No, it may have executed as a market order.

And that's the point he was trying to make. He's saying that the broker can create any suitable excuse to fit the situation.

With HFT it may not even be an excuse and could very well reflect the reality of the situation i.e. the price has moved too quickly for the exchange to keep up.
Cool. I've always expected JIT could eventually beat AOT compilation, though I haven't heard of that being commonly seen. I'm a little surprised that C++ still tends to use crude vtable dispatch just because that's what Stroustrup demonstrated and it's easy.

There's a long road ahead. It's way too soon to pick a winner. Many people will have lots of opportunities to engage with Google's offerings for many years to come. And they'll have lots of time to refine their products. I think Google+ was a smart move. Maybe they haven't been hugely successful yet, but I see potential.

Interesting idea there with the mannequin. This bypasses some of the limitations of just applying clothing textures to the 3D model. A mannequin would probably give a much better indication of how items of clothing stretch (or dont stretch) in different places across the body. I imagine this would be very difficult to simulate with current tech.

Logistics though? How do you (cheaply) mass produce mannequins with entirely different dimensions? 3D printer?

Also how would the clothing be fitted to the mannequin? Robots? Do we have a robot that can dress people yet?

I've seen children have amazing 'attention to detail' and I think there's a simple explanation: they don't have anything to do other than look at the world. In fact, their entire existence in early years is in dealing with understanding the world.

I saw this in action the other day in a local coffee shop. In front of me was a mother with a child of about 4 who pointed out to her mother than high on a shelf above Italian coffee machine was a small, plastic toy from the children's program "In the Night Garden".

I certainly hadn't noticed it and neither had the mother. Which isn't surprising because the mother (and I) were in the coffee shop with a head full of other stuff (buying coffee, work thoughts, relationship thoughts, etc. etc.) The four year old was in full observe the entire world mode. Given that he didn't have a purpose (like buying coffee) he was free to look around.

Uh, cheating?

"Cheating - Know How to Fake Data

Awesome technique. The fastest function call is the one that doesn’t happen. When you have a monotonically increasing counter, like movie view counts or profile view counts, you could do a transaction every update. Or you could do a transaction every once in awhile and update by a random amount and as long as it changes from odd to even people would probably believe it’s real. Know how to fake data."

So all those people who buy views are kinda screwed now :-) I suspect this is a bad example. I HOPE this is a bad example, if only for the KONY2012 campaign :P

Ask HN: Should you downvote based on disagreement alone?
This came out of a discussion in the comments of this post:

http://news.ycombinator.com/item?id=3760013

I'm getting more and more frustrated with the amount of downvoting on HN recently. Otherwise rational arguments that happen to contain unpopular opinions are the canonical example, but sometimes the reasons are just puzzling.

So I thought I'd make this post, so we could discuss it as a community - is it OK, or is it not?

In my opinion, in addition to being rude, it's ineffective; the person who got downvoted is never going to change their opinion based on what you say, and it's important to keep in mind that they're not always wrong; many times I've replied with a disagreement, and either learned something or changed my mind completely.

Obvious trolling or childish arguments are a different kettle of fish; we're actively trying to push those people off of HN, which is what we're doing by hitting the downvote arrow.

What does everyone else think? I'm happy to be proved wrong about this, but I think it's important to have the discussion, and I'm not sure we have recently.

As pointed out by avree, pg five years ago said it is OK, because people upvote based on agreement:

前列腺肥大怎么治疗
I remember precisely the period when GMail was launched and I received an invitation from a friend. Until then I've been using private email servers with local clients + Yahoo's Mail.

My first reaction to GMail was somewhere along the lines ... fuck, this is too good to be true.

The same thing happened when I discovered their search engine. I've been using Altavista and I actually was late to the party. So here I was in an Internet Coffee, frustrated that both Altavista and Yahoo were giving me shitty results, then I saw somebody using Google and I tried it out. The results were visibly much, much better and the interface was fast, simple and effective. And I would tell the same story for Android right now, if it weren't for Apple's iOS that came first.

The article completely misses the point of why Google is Google. They are engineers fixing things. Which is why I don't blame them for trying out their luck with Google+. The problem is indeed that they haven't fixed anything in Google+.

What really worries me is that Google is losing their culture of tinkering, their playfulness. They will soon fail to capture new markets, to further innovate, then they'll become evil, using their amassed wealth and influence to crush competition and to break standards.

I agree that hacker-ism is about keeping truth and contempt for authority. A true hacker will create an innovative solution for that problem. Good example is Richard Stallman, when others used law and authority to stop him from hacking, he went on to create GNU, wrote emacs and released it under GPL. Some hackers may write a language or OS, while other hackers may create a business. There is nothing wrong both. It is based on the personality and specific problem they are hacking. The point of this post is that we focus on the positive aspect.

Why slow sometimes is fast
It's easy to monday morning quarterback and say "oh, OF COURSE any competent dev. should know all this inside and out, it's basic stuff from 200 series CS courses, if that". But that misses the mark. For one, it's enormously Java specific. For another, some of it isn't very relevant to most coding. How often is it really necessary to code an abstract class in Java? How often is it really necessary to know all the trivia of protected access?

This ranks pretty high on the least useful knowledge that you could probe for in a developer. The only reason it's even remotely successful is probably because there's a general correlation between experienced coders and coders who know these subjects well. But it's nowhere near a perfect correlation, you can be certain of that. It will eliminate people with talent and select for people who know trivia but lack talent.

Imagine it like this, you spend several weeks and thousands of dollars courting potential candidates for the love of your life. And on your ultimate date you ask them what their favorite band is and move on or forward based on their answer. Reality is a lot more complicated than that.

Try this test at your work. Identify your developer coworkers who you look up to, and come up with equivalent topics for their coding platform of choice then randomly ask them about them. For example, drop by and say something like "hey, I always forget, could you explain abstract classes to me?" Or something like that. I'd be curious what the results were.

Maybe there's nothing to theorize about that's specific to girls? Sounds like my story, as a guy, and that's a subtle but important point. I used to run every program I could find, copy stuff from friends computers that was new and unfamiliar, borrow books from library/parent's friends, etc. Eventually I stumbled onto BASIC and the rest worked its own way out.

Yet I know plenty of kids - male and female - who had a machine just as powerful as I did (some more powerful), had the same access to information I did, etc. and didn't bother with any of that. Why was I so inquisitive and interested in computers to exclusion of everything else? Why did I spend all day and night on them while other kids were experiencing their first drinks, their first relationships, hanging out together, etc.? That's a more interesting question than the sex one, IMO.
I completely agree. I just saw a C++ thread where someone has posted decent enough code and its greyed out without a response.

> I also agree it's narrowing, and admit that what I was suggesting is a 'low-tech' solution.

That's not in itself a reason to reject an idea. A lot of the time the best solution is decidedly "Low Tech". Thinking that added complexity has any correlation with the usefulness of a system is a fallacy.

(Example: http://thedailywtf.com/Articles/Classic-WTF-Lock-and-Key.asp...)

It's not even that your idea is bad. It's not. I'm just skeptical of the availability of individuals who can make a difference without being out of the price range of just about anything that could be defined as a "startup". In fact, I'm skeptical of the availability of such individuals at any price range.

And I'm afraid that if you're serious about the idea that the onus is on you to figure these things out and prove their worth.
If it's mainly noise, why do you care?

What I find most amazing is that the stock market is relatively small, yet people have strong opinions about it while ignoring much larger markets. There's some adage about how if you can't measure it, it doesn't exist or something. If CNN doesn't run a ticker for some market, I guess it doesn't matter.
I completely agree. There are a fair amount of investors that are going after a percentage of a company, they are making investments that can actually propel a company forward. The rest of us are gambling on a popularity contest.
Wow. Extraordinary claims require extraordinary evidence, but Irv Weissman and his lab are the real deal. Here's the original article (which is open access): http://www.pnas.org/content/early/2012/03/20/1121623109

Of course, this isn't the first time we've seen such promising initial results only to hit roadblocks in translation, but here's to hoping it's a real effect, even if it eventually turns out to be less than a true "cure"!

The Histogram as the Image
If you take one of these good developers, nothing much, other than that they might need to write some things that they wouldn't have to think about in other languages.

If you take a developer who isn't as good, or isn't as experienced, and they create a ball of mud, it's easier to get it to a maintainable point by a good dev if it's written in a language other than PHP.

Some things about PHP that make it difficult to maintain over time are things like lack of consistency in abstraction, lack of first-class objects, extreme behavioral dependency on php.ini, incomplete reflection capabilities, and so on. These types of things are much bigger of a deal when trying to refactor a messy codebase as opposed to developing on a pretty clean one. They're getting better as time goes on, but the other popular web-dev languages are miles ahead, and it's extremely likely that a good dev capable of writing PHP code is familiar with one of them.
Um, no. Maybe they are transparent once you've signed up, but until you do, they are opaque. My best source of information on their actual speeds, rather than just the burst rates they advertise, was Wikipedia, and I'm sure that was at least a little out of date. As for pricing, I can't find any concrete information on that past their special offer period, even if I give them my exact address.
If you didn't file something, provisional/patent, and no other application is accepted/pending with earlier date then your app release date, then it's probably public knowledge, and a prior art that will block anyone from filing.

but Facebook's full of people who I don't want to talk to! I've got 412 facebook friends, and you know how many of them I actually want to talk to? Like seven. How many of them leave comments on anything I say, though? Like 30 of them. The 30 who I like the least.

A simple solution is just to revert to showing vote numbers, but not affecting the comment whether the vote is positive or negative. Then have a separate system for flagging comments (like articles are), and comments that are flagged get the grey treatment. It separates the 'I disagrees' from the 'this is bad content'.

Flagging should still have some minor hurdle - like a click through page or similar - otherwise it'll still be too trivial to silence folks with dissimilar views, something that a site catering to self-appointed mavericks should be concerned about.

As it stands, a single dissenter can discredit you with no accountability whatsoever, and this causes much frustration.
> The erroneous/ cancerous will be replaced with the healthy DNA

Human DNA, weighing in at gigabases, is too large to fit into viruses. Also, 'replacement' implies getting rid of the bad stuff, which isn't really explicitly contemplated here.

Finally, if you are good enough at identifying cancer cells from the outside that you can target them for DNA replacement, you'll probably be better off by just killing that cell.

I believe that IT is unwelcoming to women, I really do; traditionally male dominated fields are always hostile to women, even after they've reached population parity, and moreso until that happens (there are more men in the field and fewer women, so more interactions will be male-female than with a less skewed ratio, which means both that women experience more harassment, and men witness less of it). You don't need to argue this point, I know that a lot of guys are assholes in any field, and I don't for one moment doubt that any of the stories about what women have experienced are true.

I'm just not yet convinced that a significant number of women actually avoid the field because of this (and scattered anecdotes aren't convincing here since the numbers in need of explanation are so huge). Primarily because women rarely enter the field - no, that's not right, because they rarely even enter preliminary training for the field, in the first place, so there's not much of a chance for them to be driven away by the behavior of men in IT at all.

We're losing women very early in the funnel, and I need some real evidence to swallow the claim that the pain that the 17% (or whatever small number) that end up in IT experience is the reason we lose the first 33%. As someone that has paid a lot of bills by working on conversion funnel optimization, I can tell you for sure that I'd absolutely never assume, a priori, that the latter part of the "women in tech" funnel was the one we should be focusing on, based on the numbers - you always look upstream first, especially when you see stats as bad as in tech, and only once you're satisfied that those are the best you can achieve with reasonable efforts do you start to look at later steps.

If the freshman CS male to female ratio was 50/50, I'd agree that we should assume on-the-job treatment was the "leak"; but it's not, based on ETS numbers, by the time girls take the SAT, they only make up 12% of the people intending to major in CS - there's already a 9 to 1 ratio, even before college! The ratio for in the workforce is actually better than the corresponding rate upon entering college, which means more women end up moving towards the field when it comes time to picking a job than away from it. [see http://en.wikipedia.org/wiki/Women,_girls_and_information_te...]

I'm not satisfied that I've ever heard a good answer to this objection. I have heard many plausible reasons that girls are either not interested in, pushed away from, or not pushed towards tech, and that's a separate matter, the one that I think is most worthy of discussion. But it has absolutely nothing to do with the behavior of the men actually in the field, at least as far as the arguments I've heard go.
