> why should you do better?

It's a zero sum game, but one might be smarter than others. Some companies doing algorithmic trading consistently skim off their share of the market's inefficiencies.

What I'm wondering is how much of an investment it would be to get into high-frequency trading for yourself. Any idea?
> One important thing to point out: functional programming and object-oriented programming aren't necessarily mutually exclusive.

I'm not sure that's true.

The essence of functional programming is treating a program as evaluating a function without carrying around state, a declarative approach that promotes things like pure functions and referential transparency.

The essence of object-oriented programming is passing messages between objects with identity, state and behaviour, an imperative approach and one that fundamentally relies on late binding at run-time.

Aren't these styles mutually exclusive?

Of course, you can have tools representative of both styles, such as higher order functions and abstract data types, in the same language; the languages you mentioned all do. But whatever merit the resulting hybrid programming style may have, I'm not sure that style is properly called either functional or object-oriented programming.

I read Investing for Dummies back in 2004. It taught me all the basics I needed to know -- mostly lingo, since I had no clue what all the TLAs meant.

I had just gotten my hands on a few thousand dollars that I knew would otherwise be wasted on an unnecessary purchase, so I signed up with Ameritrade (back in 2004 when it was much less user-friendly) and had to read the book before I felt confident enough to actually place an order.

The book advised me to buy what I knew, and to only buy something I planned on holding for a long time. Luckily I had just tried out a Powerbook for the first time and was blown away, so I bought a bunch of Apple stock.

From what I've learned, women use talking to clear out their mind, to reach a conclusion whereas men like to talk only after they're reached a conclusion. This also sets expectations in men and guides how men respond to women.

When a person is talking, men expect him to have a point and get there quick. This won't happen when a man is listening to a woman because women talk to find out themselves if there's a point at all. You can guess this can be totally boring for the man if he's stuck with the idea of just waiting and waiting and waiting for the woman to get the point. Soon the man will just learn that the woman's talk never reaches his expectations and stops listening. It's not about physical hearing, it's about mentally filtering out anything she says.

Neither approach to talking is wrong, they're just very different.

I've made it a point for myself to listen to my wife because I've seen how tremendously important it is for her. I don't expect her to get to a point and I'm not waiting for an interesting issue to be revealed in the end that I can then solve for her. I just listen, nod, make short comments, and what I expect from the discussion is her feeling better instead of a point getting delivered.

I actually had this debate once when I was a member of my local town council (in germany. A small business started by a woman in her garage had to shut down and I cited HP and other famous "garage" companies and asked if we would have shut down their business. The answer I got was "Yes of course" the vote afterwards was 12-1 for shutting it down.

On the other hand there is a lively startup scene and especially the online business is quite forgiving so it's not the same everywhere in germany.
It blows my mind that this is taken to be true. There is a LOT of literature that "supports" these ideas, but a lot to the contrary as well. And there's lots of garbage out there if your primary source for this data is Google searches or a few free blogs (I like Sethi's blog, just don't buy into a lot of it).

>.Big shot fund managers can't consistently beat the market...

1. My understanding is that literature regarding this generally refers to the mutual funds. I've also heard it voiced that the mutual fund community on average doesn't beat the market. That's not the same thing.

2. Renaissance. Quantum Fund. DE Shaw.

Why?

> the market has always had a positive return over any 20 year period.

1. Some people want returns in timespans of shorter than 20 years.

2. Not all markets have had positive returns over all 20 year periods. Even US equity markets have had losing 10 year periods, and inflation adjusted returns make the picture bleaker as well. I'd say the SPX has a good shot at not beating inflation adjusted returns for the 20 year period beginning in 2000.

He's making shallow copies of all of his objects and many of them.
There are so many facets in object-orientedness and you can ignore many of them and still have something that's clearly object-oriented.

For example, object-oriented doesn't mean you have to store all your state in objects and that objects must thus be mutable. You can, for example, return new objects of the same kind with new, modified state.

I love the idea (for the guys who run it AND the guys who it opens up opportunities for).

Might be something you could play with.

Depending on what sort of HF strategy you want to run, I imagine this can be done relatively cheaply. (300K-800k? Pretty wide range I know... that's all I got though).

Obviously your strategies are limited, you're not competing with some of the super low latency firms for the fastest of opportunities because of hardware limitations or price prohibitive vendors/deals with exchanges or whatnot.

While the difficulties you outlined in adding a USB port are not completely trivial, they are pretty close when compared with the rest of the technical difficulties and problems overcome in building the iPad at all.

If Apple wanted to, they could produce solutions to all those problems and give it a USB port. Or support Flash. Or whatever.

Where Apple spends its technical talent just reflects what's important to them and how they envision the people using this device.

I don't often agree with Jeff Jarvis, but I do here. The iPad is a device designed for consumers not creators.

I've noticed a certain anti-intellectualism going around this country; since about 1980, oddly enough. … I was in Nashville, Tennessee, and after the show I went to a Waffle House. I'm not proud of it, but I was hungry. And I'm sitting there eating and reading a book. I don't know anybody, I'm alone, so I'm reading a book. The waitress comes over to me like, [gum smacking] "What'chu readin' for?" I had never been asked that. Not "What am I reading?", but "What am I reading for?" Goddangit, you stumped me. Hmm, why do I read? I suppose I read for a lot of reasons, one of the main ones being so I don't end up being a fucking waffle waitress.
I've found that I fall into the "not playing with enough money" camp. The difference between the "gotta start somewhere" attitude of software development is trading costs money. I found I was consistently making 20-30% returns, but after trading fees it was a lot more like 0-5%.

You can write as many Hello World programs as you want for no incremental fee — but every trade costs money, so you need to trade enough to offset the feeds.

It's a zero sum game

It most certainly is not.

When you buy shares they represent a share in a company. This company may rise in value due to good management, successful products, expanding into new markets, etc. If you sell your share at a higher price, no-one is going to lose the money you will earn, the company is just worth more than when you bought it.

Other securities may make you money in other ways, e.g. if you buy T-bills the FED is paying you interest on the money you effectively loan them.

Mortgage bankers (i.e., bagmen for the brokers) would get involved briefly, just long enough to write the mortgages and flip them to get their capital back. But the CRA didn't regulate mortgage banks, only actual retail banks with FDIC-insured deposits. And if it had it still wouldn't have required the laughable lending standards they held (because they knew the risk wouldn't be theirs).

Betting that Marc is talking about RethinkDB.
UGC is overrated. He mentions this in his article: Twitter, e.g., is thinking out loud and not a lot more. Yeah, it's fun, but is it good for you? Sure, why not. Twitter's a conversation at least. But have you ever read a YouTube comment worth reading? And it's damn hard to find a blog, even a really good blog, where the "Comments" h2 tag isn't a sign to gtfo before you remember how stupid other people are.

I think there's a parallel to be drawn between user-generated content like comments* and what the Web has done to the magazine format. Compare say Slate.com with a really good old-media magazine like Harper's or the New Yorker. The former is throwaway, largely vapid, blog-format pageview fodder, terrible podcasts, or dull echo-chamber commentary on the real, long-form kind of reporting and thought perpetrated by the latter. Slate pushes more words than Harper's, it's probably fair to say (and scare-quote) that they "actively engage" more of their "readership" than Harper's, but this is not an unmitigated good. Sometimes it's good to stop and take a breath and think, even if it's just for the 1.5 seconds you lose having to hit the home button before you can switch to your IM client.

This isn't a categorical judgement on "content creation", but it's important to consider what exactly is meant by "content". Jarvis seems to be longing for the brave, relatively new world where you can add your blather to the bottom of the first page (~180 words, skip the rest) of a Time.com article on the Michael Jackson heirs. The iPad is perfectly capable of thoughtful aggregation and creation of content; what it doesn't lend itself to is millennial ADHD "multitasking" and throwaway content. (I think there's a breed of geek that has the idea that the internet really is a lot like the Matrix: you get images and text thrown at you for a while and all of a sudden "I know kung fu". No, you don't, you just wasted hours of your life passing your eyes over disconnected words that you will never remember, synthesize, or regain.)

If you're interested in reading a book or two, thinking about them a while, recording your thoughts, maybe make a drawing or two, a blog post, etc., the iPad is perfectly capable of aiding your schemes. If you absolutely must watch two TMZ video feeds (and firstpost on the comments thread natch) while updating your work/home/secondary work tweetdeck streams and copywriting top-ten lists for your blogs.com subsidiary, yeah, you're going to want something different, but I don't want to be your friend.

Right. It's the classical data mining problem. What should be done is to take the reasons given and use them as a hypothesis to predict other events. Reinhart and Rogoff have done just that in their book. After reading it I find it very difficult to accept the claim that people predicting this crash were just lucky or that all their reasons are bogus.

And I think you're making a mistake to equate ball games with debt markets. The fortunes in ball games can quickly and unpredictably turn. Debt doesn't work that way. If many people on low income take out mortgages on a teaser rate that goes up two years later to levels they cannot afford unless house prices keep rising at historically exceptional rates so they can remortgage, you know you're going to be in trouble eventually.

It took him +1000 words to say "when it's ready". That was an epic feat of verbiage.
You're correct - none. I could make the argument that many people would pay for the new upgrades to their compiler, text editor, etc at least yearly, but you're right that they didn't have to to continue using them. I'm not sure that matters though - even as a yearly fee, $99 just isn't that expensive compared to how thing were in this supposed Golden Age, even compared to the old one-off costs - especially inflation-adjusted.

To be clear, I'm not saying things wouldn't be better if this was all free of charge, or that Apple's tight grip on the platform is great for society (I think that's a different argument entirely). I'm just saying that the argument that everything was better and more accesible to new users in the old days is a bit of a 'rose tinted spectacles' one.
It seems pretty clear to me it's about the perceived differences in skill. If I played Bobby Fischer, I might be tempted to give up too- I've played chess maybe 50-100 times in my life.

In other words, if we see the opponent as within reach, or even just a little out of reach, we will struggle to get there. However, if we see the opponent as completely unreachable, it would be foolish to expend energy on an impossible task!

And as whatwhatwhat said, this effect applies EVERYWHERE. The psychological impact of 'first blood' in a fight, or shock-and-awe campaigns and other morale issues in armed forces also comes to mind.

There are both low-level and high-level corruption. Low-level corruption is the naive version that is handing over actual notes to officials to have small things get through the system. High-level corruption is a lot more subtle and transparent than asking for tea money, circling around anywhere where any people have some political power. The high-level kind of corruption is firmly rooted in western countries as well.

It might actually be easier to fight the low-level corruption because the tea money is clearly and undeniably out there, and such blatant bribery is easy to judge. On the other hand the high-level corruption isn't supposed to even exist. The status quo will tell us that there's very limited corruption in many western countries. Further, no physical notes ever change owners but instead agreements, benefits, rewards, slices of power, changes of opinion, and political agendas get from one side to the other.

And all that can be put under the cover of public relations as usual. It's just public relations between those who have money and an agenda and those who have political or journalistic or whatever power. Seemingly everything is immaculate. In reality, it's as dirty as it can be.
