Voted for Fun and testing new technologies, but like someone mentioned before, it is the creative control of a project. Not ruining a perfectly functional and UI designed application or website and have a client have an opinion that changes the whole dynamic of how it works.

Olark (YC S09) is Hiring a Backend / Rails Engineer
One big motivation for me to work on side projects is that (since I don't expect them to be really successful or anything,) I don't have to be pedantically pragmatic about the choices I make. What I mean is that I get to do things the 'right' way, not the fastest-to-ship way.

I get to write code in _my_ way, not in the way that business requires it to be.

Doing it the right way _does_not_ mean that it will not involve hacks or clever techniques etc. It just means that I get more time and space to think about the choices I make and I get to model my data-structures, code and the visual design in the best way possible (for my definition of best).

I like the fact that I can look at the same piece of code for a few days and refactor it like crazy.

I have found that this eventually helps me in my day job too.
Thank you. Oscilloscope is right - most of the data is from the NOAA - CSV files in my case that I process with a script into the large .js array. They don't have any data for this year though and I felt like I had to have Sandy in there so I had to scratch around a few places for that.

While this was quite fascinating, I couldn't see this form of trading as anything but a zero-sum game. Some players win, the other lose, like in any other game.

Except finance is supposed to be "serious". In most serious, legitimate activities, extracting money means you provided value somehow. So, what value high frequency trading could possibly provide?
There's no doubt that Elite is an ancestor of EVE and many other games. But clearly they're going to implement a superset of the features the original had, and I don't get the impression that the end result will be very similar to EVE. That said, an early single player version of EVE wouldn't be very similar to EVE, either; I get the impression that EVE is almost purely about player relations and the metagame.

On an unrelated note, you could land on planets in Elite 2. That totally blew my mind back then. Sort of like a real time lo-fi version of Powers of Ten[0] running on your computer.

MIPS is a great example of the kind of tech company that wouldn't exist without some sort of intellectual property protection. They're specialists in chip design--they don't make any physical products. The whole value of their business is their designs, which are protected by their patent portfolio.

In MIPS's case, intellectual property protection made it possible to compete on designing CPU's rather than designing finished products for those CPU's to go into. It allowed them to focus on chip design rather than fab design or manufacturing. And it allowed them to accumulate something of value in the company itself that could be sold later.

Would CPU's get designed without patents? Of course. But I don't think the sort of beneficial division of labor you see with MIPS and ARM would be possible without some sort of intellectual property protection. When you can't easily transact in something, that forces you to try and move every operation involving that thing under one roof. And it's not hard to make the case that those kinds of monolithic companies are worse for competition than patent litigation.
Nothing in HFT is free. People doing this for a living use precision time protocol in a colocated data center to build their own timestamps. However you can get started by buying ITCH, OpenBook, etc... data which has the full market depth feeds for the various exchanges. There are a couple of brokers out there specializing in the space.

If the easy part was building a working model either you got incredibly lucky or the model is wrong.

Yes. Or at least their stick to beat Microsoft with when it come to negotiating access to the Windows Metro UI in Windows 9.

The desktop environment isn't going away in Windows 8, so platforms like Steam will still be able to run. Windows 9 though? Anyone who doesn't have a head full of rocks can see that Microsoft might decide that only "enterprise" installations of Windows get to keep the desktop UI.

Valve really, really need to be negotiating from a position of strength when and if Microsoft decide that's the road they want to take.

This point about Google and Facebook is interesting, not least because Google has certainly had numerous people join the campaigns. My guess would actually be that the level of testing by the campaigns (just based on the small subset of data that PP has) is incredible and much, much better than either of the tech giants - regarding email.

As a benchmark, the most analytically savvy paper mailers / marketers of the last 20 years could arguably be Capital One. They did elaborate testing that involved not running TV ads in markets for years at a time, tons of different message styles, frequencies, etc - all because optimizing these results was worth so much to them.

In short, if getting email right means millions of dollars, then there's a premium on getting it right - just as there is for Google for nailing search testing.

You mean ... if they only have a lower powered ARM device, with Windows RT, they are forced to go through the store... Or if they can't figure out how to get to the Desktop with their Windows 8 device by clicking an icon/tile.

At some point you're going to have to make a choice whether you need a Desktop/PC, a tablet with Windows 8, or a tablet with Windows RT for whatever it is you need Windows for.
Guess you are familiar with http://en.wikipedia.org/wiki/Survivorship_bias? In 2009, there were probably tonnes of people trying to exploit the market using similar low-tech methods as you. Even if all of them were at best break-even, some of them likely made a lot of money on their unprofitable algorithms by pure chance thanks to the size of the cohort. Those few blogged about it and those who lost money didn't. :) I'm not saying that you just were lucky (please dont take this as criticism) - survival bias is just one of those things that always come to mind when people write about how they broke the market or when some investor is presenting his incredibly smart investment strategy that has netted him millions.
Nice! It isn't anywhere near accurate however, some of the foreign results were simply comments on the election and one in the States I saw was actually a comment on 'I'm not telling who I voted for but it sure wasn't Romney' and it came up as a red tweet.

Still this is a funny, little experiment. Great work!
Thank you and no, not a basic question at all. One of the cool things I noticed too is how the equator seems to be a barrier that cannot be crossed. I think it's connected to the Coriolis Force that is required to form the low pressure trough and form/keep the storm going. That force gets to zero at the equator I think.
I hate my job. I made some stupid mistakes in picking my first job out of college and it's pretty bad. I was shuffled into a position I didn't sign up for (business analyst work instead of development) and the culture is extremely toxic.

I've been trying to get out but so far having this company on my resume has been a huge red flag to anyone hiring actual developers making it very hard for me to find something better.

Side projects are my way of proving myself as a software developer. I'm trying to build up a GitHub profile of projects which I've seen through from start to finish. My current project is an excuse to learn about the Play! Framework and asynchronous web development with Akka actors.

CISECO - Miles here, sorry guys if you found it confusing, we tried for days and over many many different people to get it right. I guess something right for everyone would have been war and peace and it's already too long.

The majority of the devices are SPI or I2C, the XBee socket being serial.

The schematics will be made available after the project ends.

There's only so much that can be fitted in the space without going USB. Where it makes more sense from cost or choice we left it USB, if that's not what people are after we are always here to listen.

£5-10 USB wifi or £20+ going SPI/UART, the choice I think is right.

It has nothing to do with EVE online

If the Pi isn't stable we will look to do a ground up Linux box, there's plenty to base things on. Our TI rep was too slow to get us what's under the Beagle, so Pi it was.

You are correct that no individual can. But firms can. And some do. Its not gambling. Its not heading down to the roulette wheel. If someone puts on millions of trades and wins a statistically significant portion of them you would have to say its not gambling. Its trading with a statistical edge.

>And that's exactly who Metro is for.

You have to realize though that that's the majority of the market. Most of us aren't programmers who need Visual Studio, or to run servers. So while they may not be getting rid of the desktop (and I don't think they are), it will become less relevant. I'd wager the majority of Windows licenses sold in five years will be WOA. The main thing holding "classic" Windows in place is familiarity, and as you said, games. I think Microsoft looks at the Xbox as hardcore gaming and the PC as "casual", but frankly when it comes to Microsoft and gaming I don't pretend to understand their actions any more. I just hope they realize it's one of the platforms largest selling features over competitors.

>The author is suggesting that there is a grand conspiracy at Microsoft to lock all 3rd parties out of Windows eventually unless they go through the App Store, and to restrict all Windows versions to Metro mode.

You know, I kind of agree. I don't think there is proof other than "it's the logical thing for a company to do".

>I'd like some proof to this because it just does not make sense.

30% from all software sold is a pretty good reason in my mind. Microsoft has Apple envy, and for good reason. Apple is filling swimming pools with dollars right now. Microsoft already has the market share, in both home and enterprise - I have no doubt they want to take advantage of that. If they could move those users to a "faster, safer, easier" interface where suddenly MS makes a cut of all profit - well, that's a really smart thing for them to do.

There's a subtle detail in Windows 8 that makes me look at it this way. It's the way that the desktop is displayed as an app, like it's there for legacy support. You don't boot to the desktop, you boot to Metro, your new interface.

Agreed, working with APL has been an extremely valuable exercise.

My fixed costs were $2000/month. I think it was $1800 for TT plus $200 server rent so damn.. I was getting overcharged $800!! oh well :)
The same could be said of HFT. Traders are "skilled" at having nanosecond access to the orderbook, having their servers co-located in the same rack space as the exchange itself. They are also "skilled" at recognizing a price movement nanoseconds before it actually happens and getting their order in just in time.

But the HFT game changes and you have to keep up. Just as a poker player from 10 years ago would not survive in the game today without adapting his style of play.

I think the real problem (as with so many problems) is definitional. What does "gambling" actually mean?

If I tried to kludge together a definition, I might come up with something like:

>Risking the loss of something of value in exchange for the possibility of gaining something of greater value in a situation where the determining factor of losing value or gaining value is random chance

The problem with a definition like this is that, as others have pointed out, it applies to vast realms of human endeavor, from founding a company to playing the lottery. It also includes no distinction between risks with a positive expected value and risks with a negative expected value.

If a lottery has ten $1 tickets for sale and each ticket has an equal chance of winning, there is an obvious difference between the prize being $11 and $9, but buying a ticket at either price is just as much "gambling" in the common parlance.

What we really need is a word that only refers to gambling in situations with an expected value less than or equal to zero.

I like the idea of Light Table but what is a deal breaker for me is that it feels like there is an ever so slight lag between pressing a key on my keyboard and the character appearing in the Light Table editing area.

I am very picky about the way typing feels in an editor, and if it feels slightly laggy or slow then that editor is not an option for me, even if it does have all sorts of other awesome features.

Does anyone else feel this or is it just a problem with the app on my MacBook?
One diffrence is these data flow stuff threw the code. I have not seen that anywhere else. There are some otherthing that are diffrent. The way they want to handle files for example.

I would say that Light Table is nothing revolutionary but it is long awaited evolutionary. Finally a modern envoierment that is really easibly extensible.

Emacs is great but you have to admit that it is truly aged. Things like eclipse are diffrent from these dynamic smalltalk IDEs that LT trieds to be like (without having the same weaknesses).

You're right - there should be more comments. I apologize.

There are a number of three.js specific tutorials out there - Google will find them for you - that will give you a simple app to play with and then it's just a case of experimenting, asking targeted questions and having fun :)

For me, the beauty of this approach is that all I need is my browser and an editor - make a change and hit reload and you see the results vs the more traditional edit/compile/link/run that I'm used to.

I want to win. I'm not sure what I want to win exactly, either a pat on the back from friends, an e-pat from imaginary friends on the internet, a double take when I tell someone what I did. I'm investing right now in my life, I'm 22 (23 in a week!) and I have no responsibilities. I'm unemployed (haven't looked for jobs, as I don't want to have a boss ever again). I'm investing my time (as I have no money) which is something that cannot always happen. I'm stretching the boundaries of my brain to do the things it can when no one tells me what to do (I like to think of it as wandering in a forest without a compass. It's lonely - none of my friends are thinking about the same problems I am at the depth that I'm thinking about them, but very rewarding. I'm investing to learn things that I will be unable to when I have money.

I like to be ignorant as to how hard a challenge is. I watched an episode of numbers last year about prime numbers (not a computer scientist so I did not know many of the complexity things and ways of finding primes, just a lowly self-taught programmer), and boom, off to the races to solve the primes. I never once slowed down enough to say hey... people have been doing this for a long time... just me and a friend trying to be naive and find a route no one found before. I think that's what gives me a lot of momentum, not putting things into perspective, and gives me motivation to keep working. It's awesome to run the show, to stop working when I get bored, to see and understand the smallest to the biggest details in what you're doing. To know the rationale behind all the decisions. Even if they're small ones, and there's only 100 decisions to make, being able to say "This is why I did that." and give a specific, personal, reason i awesome, rather than making excuses or attributions for why something did or did not happen.
There is a huge trust bridge that has to be made for app store users, and I trust Valve more than I trust Google, Amazon, Apple, or Microsoft.
If File.rm("something") is undoable, then its not a problem right? We are talking about developer tools anyways, its not inconceivable that a mock environment would be setup for the program with undoable side effects or what not. However, this would require serious programming model changes, which are probably not in the scope of Light Table.
