I tried to address this concern at the start of my post. If you have some idea of how I manipulated the statistics I'd be happy to respond.

Having said that I can agree that my case is pretty unusual and that everyone should beware of attempting to do something like this. Even for myself I couldn't do it now. (There is a reason I turned my program off.)
I don't think they'll get rid of the desktop, I just think more and more consumers will choose ARM devices. Regular people do little more than chat on Facebook, check their email, and do light internet browsing. If they can do it from a tablet device for half the cost, they will.
Nepotism is a live and well at the local and state level. If anything it works just fine at the national level, the difference is that today's politicians have become very adept at keeping you from finding out. Better yet, when you do find out and they get caught they rarely suffer any consequences for it.

This is a different style of trading than what investors do. He said that he was never more than a few contracts in. A single contract needs $10K day trading margin usually (depends on time frame and specific contract, but it's a reasonable estimate). Therefore, if he was never more than 10 contracts long or short at the same time, the risk was of $100K.

Making $500K on $100K over 6 months is good business.

> I think for a good programmer choice of a programming language does not matter.

I disagree. I think an important part of being a programming is choosing the right tool for the job.

You might be able to build what you need using a hatchet to cut your lumber, but you will almost certainly end up with something much cruder than if you had chosen to use a saw.

So a good programmer should be able to get by with the tools he has, but should pick the best tool for the job when he has the option.
This. I love crazy projects and Show HN's until the cows come home, but this one is dangerous that I must repeat the warning to others.

I cannot emphasize how important it is to understand that people who trade using price action (http://en.wikipedia.org/wiki/Price_action_trading ) are just speculating based on where they expect the price to move. It's no different than people who play Texas Hold'em online and speculate what cards others have based on betting patterns. If you get good at spotting the patterns (like this guy did) you can go on a winning streak, but when the game changes (as it did for this individual after 2009) then you either go home or go broke.

This guy found one edge in 2009. It won him 500k. Fantastic. More than any edge ever won me. But, the market has changed so much since then, with HFT becoming so prevalent (http://www.theverge.com/2012/8/7/3226187/high-frequency-trad... ) that please be careful before you follow this course. His code is unlikely to be worth much today unmodified, and when you modify it you'll realize, as I have, that when the other players have access to the order books and can jump the line you have no chance in the game in 2012.

One last nit: Please, please post recent data when you talk about projects like this. 2009-2010 is 3 years ago. Since then there was significant turmoil in the US, Asia, and the EU. How are these returns relevant for today?
Well, in the article he said tat he did not care about direction, he would simple buy when his expected price was up, and sell when down. However, there could have easily been a bias in his model that "preferred" and performed better during upward movements. If so, he got lucky.
I'd probably focus on disaster diversity and "able to serve US-East and EU from a single datacenter". US-West (OR) + Iceland + Asia potentially better than US-West + US-East + EU + Asia. or US-East + EU + Asia.

The other thing would be having very clear and pro user terms of service, and whatever changes in national law are needed. Maybe some tech changes (DDoS protection?) + specific marketing to vertical markets (casinos, vpn providers, usenet, torrent sites, ...), but I'm not sure what the current state is in Iceland.

If you're doing colo, it's more knowing people and maybe having a few case studies. For some kind of virtualized/managed/etc. offering, then I'd personally judge based on terms of service, measured service quality, and how secure the administrative procedures are (i.e. no rackspace/linode style administrative override...)

I wonder if now isn't the time for a billionaire to start backing something akin to Ubuntu but based on a Windows clone like ReactOS? The goal would be to capture a user base that's disenchanted with the Windows 8 direction and just wants to hold onto the Windows 7 experience? One could even base this on WINE and Linux with the plentiful open source programs for Windows and some tweaks to automate installation of things like MS Office.
This story leaves me feeling helpless. What can I, living in the United States, do to change this statement:

I'd love it if someone would comment, or better, write a blog posting with a list of actionable steps that I can take to improve things.
I'd assume it's because IOS is better than ios - and no, user's tend not to capitalize, just read any Facebook or Twitter feed/stream. The general population is poor at almost all aspects of the English language. It's also not worth making exceptions for words like "iOS" when "IOS" works equally well to the average consumer.

However, more important, I think they do it because people tend to auto post to Hacker News from the bookmarklet and similar services, and it's better to have things similar rather than a bunch of differently formatted titles. Makes it more appealing to the eye and therefore easier to read.
That's an interesting reason. May I know more about your side projects and how you go about networking in those industries?
If you make that many trades and your total market exposure at any given moment is small yet you consistently make a net profit then you've found an edge. At which point it's not really gambling any more, it's just making money!

If your net exposure is small, but that's only because you're offsetting various positions then you're probably picking up nickels in front of the volatility steamroller & if you stay in the market long enough you'll get squashed at some point.

I'm compelled to create. Side-project means a lot of things to me. It could be an app, or it could be a painting, or a series of short stories examining the human condition, or an EP of instrumental tracks using mathematics as the guiding compositional tool (this is something I have explored and am exploring more of).

I wish side-project didn't have such preconceived connotations as "web app" like it seems to here. Does anyone else like creating non-tech things as their side projects?
It's possible that your algorithm is sensitive to market volatility.
It is only gambling in the sense that any business is gambling: Your customers might stop coming tomorrow because the fad wore off, or a competitor provides a better/cheaper/hipper alternative.

(And indeed, living is gambling. It's all just a matter of the risk/reward portfolie).

But jspauld has apparently made $2/trade after fees on 250,000 trading, with a very small standard deviation (I would guess less than $2/trade) - which makes it one of the best businesses one could ever have.

You can't live without gambling - by e.g. going to be a salaried employee for Yahoo rather than Google or that weird newfangled "TheFacebook" thingy back in 2004, was a gamble.

jspauld, statistically speaking, has made less of a gamble there than almost anyone else posting on HN.

True. But that's true for every single success story posted on HN, reddit, or USAToday.

Like many, I welcome the inclusion of Amazon Glacier.

I don't think that alone merited a major version bump[1], but understand that the developer needs to feed his family, so will gladly pay for the upgrade.

[1] The ability to create the backup bucket, and not have it auto-create, for example, would be something that I would consider a major version bump.

Yes, there is a problem, we just can't see it! Sigh.

Every federal government contract that has even a hint of favoritism is litigated to all hell, where lawyers comb through everyone's emails going back years to dig up any dirt they can find. If it was a big problem, we'd know about it.

Nepotism is alive and well at the state and local level. This is partly because state and local governments are far less sophisticated than the federal government in terms of process and people, and also because there is not a strong culture of litigating contracts.
Out of interest, how much capital did you start off with?

It's just boiling down the most effective parts of marketing strategy to and studying exactly why they work. And since Cialdini first compiled his work ten years ago, you can bet that marketing strategies have been significantly influenced by it.

So it's only intrinsically worse in the sense that a cup of grain alcohol is worse than a cup of beer.
While I appreciate the author has tried to take a good stab at the whole big-picture-design problem, this to me looks like a Scrum-but.

"We do Scrum, but... every so often we stop doing Scrum and get our design hats on"

Perhaps I've been fortunate in the projects I've worked on so far, but we always managed to get the UX designs done one sprint in advance. Sure, things need to be reworked as new discoveries are made. But isn't that the whole idea of iterative development?
Well I could try. But it's not going to be any easier now than it was in 2010. For four months I tried everything I could think of to keep it profitable but in the end nothing worked so I had to shut it off.
I don't have much experience with finance or working experience with machine learning, but I've always wondered how much room there was for a clever amateur to profit in this space, even as it's crowded with much more sophisticated professionals with much more sophisticated algorithms and machines.

I'm thinking back to Garry Kasparov's piece in the NY Book Review a couple years back:
http://www.nybooks.com/articles/archives/2010/feb/11/the-che...

He talks about a chess tournament in which it was "anything goes"...competitors could be human, computers, or humans with computers. The expected outcome was that a grandmaster using a Deep Blue-like computer would win, but the winners ended up being a couple of amateurs with three computers:

> The surprise came at the conclusion of the event. The winner was revealed to be not a grandmaster with a state-of-the-art PC but a pair of amateur American chess players using three computers at the same time. Their skill at manipulating and “coaching” their computers to look very deeply into positions effectively counteracted the superior chess understanding of their grandmaster opponents and the greater computational power of other participants. Weak human + machine + better process was superior to a strong computer alone and, more remarkably, superior to a strong human + machine + inferior process.

So in HFT, how much room is there for an amateur to profit over professionals by having a sophisticated process?
Agree, somehow incomplete info of the current status of the project.
It can be ambitious and in an early stage but just say it!
Or we can stop pretending like we're even a little bit confused as to what was meant at any point along the way here... natural language exists to facilitate communication and understanding, not pointless arguments over the form of idiomatic expressions.

Here's the reason I said that: "No matter what I try, I can't make it look pretty. I realize I'm such a horrible artist/designer that no matter how much effort I put in, it's always going to be an ugly mess if I do the front end. So what I appreciate most is them making it look pretty. Other aspects of the jobs I can do better, so it's not quite as important to me to have someone else doing it. Perhaps it is a "lazy" attitude, but it's not a condescending one. :)

BTW, I'm not dissing on your product at all (and apologize for going off on a tangent). It could be that Arq is the glue that makes Glacier far more superior than any kind of personal storage solution. I'm just bickering about the cost of Glacier alone...but otherwise, I think it's great to have a Glacier-accessible option.
I work on side projects (my own and others) for a number of different reasons. But primarily to see how I can solve problems. Working on non-time critical projects means you can get a bit more creative and explore a lot of different options to see which work the best rather than the quickest to integrate. Some of the side projects I work on add a little extra rev every month, some don't. The only side project that consumed a good deal of my time is the one that in fact doesn't make much money (I probably lose every month) but its the one with the largest user base and its the one that is more of a love rather than anything else.
Learning other languages is good cross-training, though. It will make you better at the two you decide to specialize in.
Looks like a good concept, but I really cannot see how this would work for functions with side effects? What if I write `File.rm("something")` and press enter?

And how would this work with, say, Ruby on Rails development?

Can anyone throw some light?
Voting is how the state tricks the gullible into thinking they have a say.

I'll give you a quick preview: more war, more bailouts, more confiscation of property. Regardless.
Not really.

A lot of people in the business would pay e.g. $5,000 for exclusive rights for something that worked this well in 2009 (with proof that it worked in 2009, e.g. verifiable broker statements), and a smaller amount (say, $5,00) for non exclusive rights.

If he claimed it still works but he wants to sell it, it is a completely different game -- because when these things work, they are cash cows.
I've used Twitter Bootstrap for a few designs now, it's a useful tool but requires you to maintain more LESS/CSS than more other frameworks (to support the responsive designs).

If you are not going to support responsive, there are plenty of other CSS frameworks out there to compare against, from Blueprint to the new BootMetro style.

If you are looking to learn web development, starting with bootstrap will throw you into learning LESS (a CSS compiler language) and into the new concept of responsive designs (where the page resizes itself to fit to phones, small devices, tablets and desktops). This can be useful for certain applications, where others responsive designs would be entirely useless.

Overall I've liked Bootstrap, it contains all the usual features you find in a CSS framework, but they throw in some other things most do not, such as a small JavaScript UI library.

Also being 18 doesn't make much of a difference, I was working full time as a web developer since 15 and knew HTML/CSS/etc when I was 9 - you will find many people on Hacker News like that. You should say your confidence level, like "I'm kind of noobish with web development, so forgive any questions if they seem obvious." Replace "web development" with anything.
Wait, he says that you cannot download an application from the internet and run it on your computer, but earlier says that you simply cannot add non-app store apps to the Metro tiled interface. Which one is it? I would assume that you can still install applications from the internet (non-app store), and I'm certain that you can have tiles for those apps. What exactly is the problem?
Staying informed is probably the best thing you can do as a front-end developer. At the moment, things are changing pretty quickly - not only with the technology, but also with front-end techniques like OOCSS, SMACSS, and BEM. Front-end is finally trending away from something trivial to something worth investing a lot of effort into. Both CSS and JavaScript techniques are going through major architectural shifts in terms of how people think about them.

Something I would add to this list is "branching out." Front-end developers are responsible for making sure the vision of the design and UX teams are faithfully implemented (if they're not wholly responsible for these things, themselves) as well as integrating with the server-side team. As such, the front-end developer needs to be able to understand the goals and objectives of these teams, which means you need to know something about what they do and how they do it. Understanding UX, design, and server-side coding practices and terminology will help you communicate better when working with these people. You'll be able to more fully understand what they're trying to achieve and the role you play in that. I'm not saying you need to know how to be a UX designer, graphic designer, or server-side developer; but you do need to know enough to communicate with these people.
Longs and shorts were 50/50 and my program showed no preference for up or down days. High volatility and high volume was what it liked.
Correct. The far more common story is "how I lost $Xk on the stock market". Probably most people with programming/AI skills have tried their luck with the stock picking problem at one time or another. I have a few times, but only in simulation. Even using very elaborate machine learning methods and a lot of training data, making money from automated trades is a difficult problem, and my impression is that it's very much like betting on horses or football games.

"A five-year federal inquiry into voter fraud that ended in 2007 found that it happens so rarely as to be statistically non-existent." This part of the article was interesting in that voter fraud doesn't happen as widely as some people believe. Really, the idea of limiting avenues of participation is probably abused by people who want to limit certain demographic groups.
You don't need a bias to accidentally make money when the market is overall moving up, do you? Picking stocks by throwing darts while blindfolded will, on average, make you money in a market that's moving up.

SMARTeacher's Adaptive Learning Platform Uses Role-Playing Games to Teach Math
To be honest, Linux is my favorite gaming platform already. I remember trying to play the original Diablo and WarCraft games on windows 7 with no success. Diablo II works ok in virtual box running XP with 3d acceleration enabled, WarCraft III pushes the virtual 3d acceleration to the limit and just runs super slow.

All of those games run flawlessly on Linux with latest wine. It might take few minutes to play with wine config and winetricks but if you're playing games you have the time to waste anyway.

Also I've played all the latest Blizzard games flawlessly under linux + wine setup (World of Warcraft, Diablo III and Star Craft II). You do need a beefy video card for those however.

A profitable predictor is a much, much harder problem.

At a place like Goldman Sachs, a quant with a working predictor gets paid 5 times as much as the IT guy who makes that predictor talk to the market quickly enough.

Because, as your question implies, it is (relatively) easy to do the IT work or hire someone to do it. Not so for the predictors.
