"Glorified gambling" is a pretty accurate description of this. However, that isn't necessarily a bad thing. If you have a situation where you can gamble with a long-term positive edge, then the proper strategy is to play with as much money and for as long as possible. The determining factor here is whether or not the combination of a particular investor's strategy, algorithm, and ability to execute will give them a long-term edge over others in the market - not whether or not this may be a risky activity in the short-term.
This is exactly the application I considered upon seeing this article.

I'm planning to loop back and investigate how restoration would work, but it seems like a potentially great way to have another layer of backup.
Can you please fix the first graph in the post? It's very hard to interpret 'gaps' in emails sent when you have Jul-12 and Sep-12 repeated.
It's kind of like debugging two programs at the same time. On one hand there is wine, wine configs, winetricks, loading directX, etc. On the other hand it's the game you're trying to run.

For example, it turns out StarCraft II needs an update process running before the game runs. So you have to find and start the correct Agent.exe --nohttpauth and only then start the actual game.exe as a different process. Then the game dumps segfaultish error saying some 3d surface wasn't initialized, which means it requires later version of directX, back to playing winetricks...

Nitpick: When exchanges have busted trades there is a "at or below $XX.XX" condition as well as the "between XX:XX and YY:YY" condition.

In the Flash Crash as well as the Knight Capital incident "up/down 30% from the Previous Close" was the price collar (anything outside that was busted and anything inside stood).

Of course there is no guarantee that the same criteria will be used the next time around so caveat emptor.
Agreed... in essence this is why we're all here. As entrepreneurs we all educated risk takers, and we realize any venture is essentially gambling if there is no edge. At any time, there could be a new idea that pushes any one HFT algorithm (or mobile photo sharing app, or words with friends clone) past the established mindshare into blue ocean territory. When that time comes, do you want to be caught with your pants down, lumbering under the excuse that you thought the oceans were too red for you to bother?
I believe all of the above apply to me. If it brings me additional income, awesome, If not, No big deal, I will have learned a lot in my endeavor.
During my path to completion I will have learned from scratch or improved my knowledge base in C#,Python, Flask, Twilio, S3, NodeJS, and my other technologies.

This side project has been invaluable.

Development is slowly coming along, But that is the way I like it.

And that's exactly who Metro is for. The Windows Desktop still remains for the rest of us, including ones that want a beefy setup, or to run productive applications such as VS.NET, or to isntall and play games that require a bit more than a slow ARM processor.

The author is suggesting at the end of the article that there is a grand conspiracy at Microsoft to lock all games and apps out of Windows eventually unless they go through the App Store (in Windows 9 specifically). I'd like some proof to this because it just does not make sense.
IPad mini In Depth: Thin, Light & Charming
If I was correct in guessing that he used XTAPI (via X_TRADER Pro), IIRC that costs around $1k/mo depending on who you go through for the front end license. I was only a developer so I'm not sure what licensing costs are for gateways, but those are the servers you connect to in order to place orders on the exchanges. He was trading the Russel on ICE, and DAX on Xetra (maybe Eurex?), so he would have needed two gateways.

If he posts the code, you're a long way from running it.
Nope, I tried removing HOME/.lighttable with LT turned off, it got regenerated back upon restart and I'm getting the same error.

I hope someone at Apple pays attention to this and they start putting Zigbee to WiFi gateways into their products. Even a little box you attach to the router with an Ethernet cable would be dandy.

Steam is more an open platform than Microsoft App Store? Really? While I like Steam, it seems to me to be the most closed and opaque of all the various app stores around

Look at Steam Greenlight, which provides a very slim chance an indie game might get onto steam: http://steamcommunity.com/greenlight

Basically the rules seem to be lots of people apply, everyone pays, and you might get on if we like you, we will set your price and tell you the revenue split. In particular, a very small number of submitted apps get onto the store.

On the other hand, getting into the windows app store seems to have much more clearly defined rules, and Microsoft is trying everything they can to get more games on.

Ask HN: Finding it near impossible to get job interviews, help?
I'm a self-taught mid-20s dev; I landed my first proper developer job at a local (Louisville, KY) startup nearly 2 years ago, we went under fairly recently and besides a bit of freelancing, I've been out of work since. I've found it nearly impossible to hunt down openings locally, so my search has been aimed at the usual big cities. Trouble is, I've barely managed to get responses at all, much less interviews. I understand that being inexperienced and out of town doesn't help my case much; but what could I be doing to attract more interviews (and hopefully jobs)? Am I crazy for even trying for out-of-town at my exp. level? How should I be finding openings around here?

FWIW: this last job was a mix of devops, backend, and mobile; I consider myself fairly language and tech agnostic (we used Ruby, C#, and Java; I use Clojure where possible in my personal hacking)
Haha, of course yes. You should start sketching again.

Along the same topic, Mother Jones had an article last month about the inside of the Obama campaign's tech operation (or at least as much as they felt comfortable revealing) that was pretty intriguing: http://www.motherjones.com/politics/2012/10/harper-reed-obam...
I've been considering trying HFT myself for a while. I'm competent with Machine Learning and am a Software Developer by day, so I can program and can sysadmin well enough to get something up and running without any trouble at all.

But, every time I've tried to actually get started, I've always found the amount of research required before being able to begin is just staggering.

It seems like the logical course of single-programmer HFT trading being:

- Find sample data

- Build your trading program using sample data

- When you're happy: connect to live API and set your trading program loose

- Iterate.

However, the first step and the third step seem like the ones which require the most research.

Is there somewhere which has a straightforward dump of timestamped market data available to download (free or not), in order to actually develop a working program?

Likewise, figuring out what to actually trade with, and which service to use is also pretty taxing.
But once they are linked we call the linkage a molecule or compound.
Don Syme on Practical Functional-first Programming with F#
The use-case that Glacier is intended for is long-term archival preservation. When archivists say "long-term", they are thinking decades at a minimum.

When you're thinking like that, you need to ask yourself what 1TB actually means. Your USB disk the the equivalent of a VHS tape in 1980... it holds a few hours of video, but to keep the quality of the original, you need to maintain it. Will a USB drive in a safe deposit box work in 20 years? Will you have a USB3 interface handy in 20 years?

Digital media is really tough to archive over long periods of time vs. paper. I worked with a US State archivist on a project, and they stuggle with the issue. They have a good handle on the papers of the colonial government from the 1600's, but have a difficult time accessing the early digital records from the 1980's.

So putting stuff in glacier, and letting Amazon handle storage migration, break/fix, replication, etc for $120 per TB/year sounds like a value to me.
Transit directions to election polling places
Just because you CAN do it doesn't mean you SHOULD. Even if you don't think of it as "gambling", you're still taking in tons of money without providing any tangible benefit to society.

If you want to make money from investing, why not do so in a socially responsible way? Invest in companies that are changing the world for the better. You might not bring home as much money, but at least you'll be able to sleep well at night.

But the point is that games are sold to consumers, and if they only have Metro, you're forced to go through the Store. Whether the developers will have access to Desktop is mostly irrelevant to his argument.
This is not even close to an accurate summary. He never stated that he had any employer backing, and he wasn't collecting market making fees. In fact he was paying brokerage fees which is the exact opposite.
Apart from the things I voted for (fun, learning, new tech, itch-scratching, portfolio), I do it for creative control. As a developer with just a little over two years experience, the world of work only very rarely seems to give a shit what somebody like me thinks I should do. I spend most of my life building things that other people decided on, in the way they decided, to the schedule they decided. People with more experience and influence than me choose the features, the colours, the technologies, the equipment, the furniture, everything.

Don't get me wrong: I don't have a problem with authority and I truly respect all those people and their decisions. But when I get home sometimes all I want to do is escape into something where I get to call the shots.
no problem, hope you like it. Let me know if you have any issues.
That's correct. Tom wrote the article yesterday (11/5) but I didn't review it and hit publish until today (11/6). Sorry for the confusion.
I would guess the big difference is the timing and non-passive nature of the stickers. Let's say I go to work and see that everyone has a sticker, I've already lost the social value of voting because if I vote after work, no one sees it. Also, I have to actually see the people who vote.

In this method, he tells you ahead of time that I'm going to be left out, so I can still gain some social utility for voting.

> You can lose everything overnight with automated trading.

I'll take it ad absurdum: You can lose everything in a second by not looking left and right while crossing the road. Or even by looking left and right while crossing the road, when someone else is driving recklessly.

It is possible to attempt HFT with not much more risk than stating a new InstaFaceGoogApple service. Put $10,000 in your margin account, and use a broker that practices proper margin checking. Tada! You're not going to lose more than $15,000 over that. (Yes, you can lose more than you put in your margin account, but not by much).

While that's more, upfront, than InstaFaceGoogApple, it is comparable to the 4 months of salary that you're going to forfeit while building the InstaFace service. And unlike most InstaFace apps, you have immediate market feedback, which can only be a good thing.

Note: Instagram did have immediate feedback from the public at large, forcing them to scale much earlier than they expected - but they did not have a feedback as to the financial value of their proposition. In fact, it wouldn't take much for instagram worth to be zero. Read, e.g. http://www.jamesaltucher.com/2011/02/my-name-is-james-a-and-... - a $100M acquisition back then is like a $300M acquisition in today's valuations; not Instagram but definitely nothing to ignore.

> With a startup, you can hit bottom. In the right market, bottom is much further down than you can ever see.

That's true. But you still have to remember that 90% of startups fail, and of those that succeed, many are just moderately successful. And yet no one keeps yelling "but most startups lose money!" at every HN story.

> When you think automated trading, you think, "Hey, it can't be that hard", and start firing up your IDE and rolling out code to talk to an easily provisioned API.

Which is what we should address, and these "it's a gamble" warning do not. When you see Suzanne Vega singing, you might think "Hey, it can't be that hard to sing". Many people do. And yet, they grow out of it, usually without trying to publish an album (and failing). This should be no different.
This. If the 2009 model worked well, did you try letting your algorithm to 'forget' the 2010 data and see if the model worked better?
There is structural favoritism, if not nepotism, in the federal system. The byzantine bidding process, requirements, etc. mean only either very large companies or very specialized companies tend to go for direct government contracts. Plus, even in cases where they are initially assigned fairly, they become a prime contractor and can be gatekeepers on every other aspect of the system. Even if their decisions are then not made on profit motives, they're not made on "best interest of the customer", either -- it's about reducing risk (of all kinds) vs. delivering the best expected product to the customer.
All of the above. To learn, to have some fun, to hopefully make something profitable.
Startups learn a painful lesson: The ‘Dropbox effect’ is a myth
My top priority when working on a side project is to work on something meaningful to me in ways that a full time job don't allow. Both on the technology side of getting to use tools I don't use full time, and working for non-profits or other organizations that would not have the ability to hire someone like me full time.
I didn't take it as a criticism of Arq. I wish costs were lower as well. On the other hand, I see there's a big difference between a hard drive vs bottomless storage that's remote, replicated, durable, and "always" accessible, so the cost doesn't seem so high to me. I've been of the opinion for a while now that the safest way to store bits is on spinning hard drives -- safer than DVD, tape, turned-off hard drives.
STUPID HUMANS!
You know, that is a really good argument.

Except two things:

1) He didn't lose money, he made 500k.

2) If this worked reliably, you would be out of a job.
"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."

I completely disagree with your assignment of value here. Playing games is fun. Configuring wine is an incredibly frustrating, bash-your-head-against-the-wall-repeatedly process that is commonly measured in hours, not minutes - if it works at all.
There is an air of either incredibility or sheer jealousy in these comments. Nevertheless, I just wanted to tell the OP that he did a great job. Thanks for sharing. I work in the finance industry as a quantitative software developer, and it certainly is not an easy job for one person to do. In fact, I tried (independent of my professional work) doing this myself, and I ended up losing a lot of money. If people are trying to do this, please please be careful. Big companies, like ones I have worked at, have technical and human resources that are vastly more powerful.
Because it's gambling. Some are better gamblers than others, but no individual can consistently have more ups than downs over a period of years.

"I was making a lot of money but now I've stopped" is the same thing as "I was lucky until I wasn't". Making a living by gambling pretty much sucks, which is why most hackers don't do it.

(You'd think that something as complex as markets would attract hackers trying to "figure it out". The problem is that due to the changing nature of the other participants, all hacks are temporary. Makes for great blog posts, but not a long term strategy.)
I don't think anyone was adapting to what I was doing in particular but rather simply adapting to the opportunities in the market.
There are a lot of IPv4 addresses that are assigned but not routed on the Internet, so you can easily "borrow" them. This kind of trick does leave a trace, though.
Quickly scanning the configuration, looks like it does. I've tried temporarily disabling the proxy in Control Panel, but no luck; I'm not sure this is the correct way to override proxy settings for Light Table, though. Where does it pick its proxy settings from?
Wouldn't the packets that <evil network> forwarded on to the real Google just get routed right aback to them, because the rest of the world thinks they are Google?

It might work for somebody like China, where they have two network interfaces, so can make all Chinese networks think they are Google on one interface, then forward things on to the real Google on the other. There might be a good reason for them to do it, too, because they are also likely a trusted CA, so could forge SSL certs, too.
You have to have the capital for the server and access to the data feeds, as well as time to burn. Also, you need to find finance interesting enough to spend time with it.
This isn't an edge case. In fact the NYT just did an expose on how this effects China[1]. You will also find this kind of corruption in every other country where the government is allowed to openly partner in private ventures. Heck we did it in America with Boeing under the pretense of security and managed to mothball our entire aviation industry.

Would it be helpful to be able to display certain buttons or other elements at a set physical dimension as opposed to pixel dimensions? For example, always show a button big enough for a finger (e.g., 1.5 cm). I ask because we recently launched a web app (www.lifesizer.com) that allows sites to display images in actual life size and think it could be great for designing mobile web sites, but comes with other implications for design, such as modifying layouts for devices with different screen sizes even if they have the same pixel dimensions.

We are currently focused on ecommerce and product review sites, but would love to hear if people think it would be helpful for a new take on responsive design.

Thank you Elliott - that is one of the things I'm working on. Hover over or pick perhaps. I imagine I'll need to turn off that feature when the number of tracks crosses a pretty low threshold or it won't be clear which one is selected.

I'd also like to rotate/zoom to the right location is a single storm is selected - Katrina or Sandy for example.
It's not often that us investing plebs can get in and bet on people like Musk fairly early on.

I did the same thing about a year ago and I'm still happy that I did, despite the stock not moving over the past year. I do believe Tesla can become a major car manufacturer during the transition to electric cars, since this period will likely be fatal to some of the weaker legacy companies.

I also realized that I may have purchased a ticket to Mars. If Musk's plans for both Tesla and SpaceX pan out, my Telsa shares will hopefully be worth as much as a trip to Mars in 30-35 years :)
