This is true, but FPGAs can still only handle relatively simple algorithms. FPGAs make certain kinds of tasks nearly trivial (think truly parallel tasks such as decoding market data for different instruments), but there's just not enough g

Most solutions of this type are an order of magnitude higher than that. It's very easy to spend $20k/mo. To give an idea of scale / endpoint, a top-tier HFT infrastructure costs on the order of $100k/day. There are probably only a half do

As a rule, downvotes with no explanation really suck. I meant this comment sincerely, and thought it worth reading. I'm quite willing to be wrong and learn, but I don't get anything from a bunch of -1s (given that I observed the no one-lin

My complaint is not that said people (those who said no one could compete on price) are wrong, but that they totally miss the point. No one buys Apple products because they're cheaper. These tablets look great, in terms of pricing and spec

Why is it necessary that the product demand "hours and hours"? I don't have a Facebook account because I simply see no need to be bombarded with invitations, connections, "friends", etc. I specifically WANT something people just use to sta

I see this "the iPad is too heavy to comfortably read" comment a lot. I have had an iPad v1 for all of 5 days, but in that time I have read more "long-form" material than the previous five months. Too heavy? C'mon, really? Yes, it's heav

True, but it's not just the fact that it's a common (and often garbage) claim--it's also about the relative worth if it's proven true. I mean, if I could really get C performance out of SBCL (and for my purposes, I can't), I'd sure as hell

Probably get downvoted for this, but as a longtime resident of Chicago who literally lives on the same block as Giordano's, why anyone would look for Chicago-style pizza anywhere, including Chicago, is beyond me. As good as San Francisco's

Maybe. Manual memory allocation is no longer a best practice for "normal" C++ projects, and I'm not sure how much easier C#'s syntax for higher-level abstractions is relative to template metaprogramming. Both are convoluted, obviously.

While I agree, what's maybe more interesting is that a community of Java users would "do it all over again". Could be blub programmers not being able to see up the chain, could be normal human comfort tendencies, but it could also be "legi

Most of the comments seem a bit critical. I don't think the author is naively suggesting "this needs to be better@#!!!". Not all ideas have to be practical or even feasible; it's beneficial to at least consider everything. The payoff o

Forget HFT by yourself, at least until you've done some things and learned what it really requires. The barriers to entry are multiple and substantial, and you can't figure out how to eliminate one unless you're really good with the others

Do not quit school. What looks expensive (in terms of time, money, and effort) now will look incredibly cheap later. "Lots of people have done great without a degree," is crap. Lots of people make $1m+ / yr dunking basketballs, too.

They're not, really. Not on the HFT landscape, anyway. It's tempting to say they're being slept on, but the cream rises to the top VERY fast in HFT--there have been multiple instances of products brought to market and the company being pu

I know HN frowns on "me too" posts, but Harris' book is the first to read for anyone wanting to get into the trading business. It's good enough that it deserves another recommendation.

To be honest, this surprises me a lot. I'm not a professional programmer, for some definition of same; but I do write a great deal of code and make my living from using and maintaining it. And for me, saying foo = bar<baz ? 42 : 0; is

It's crucial, for sure. But there are trades for which it is the only determinant, and those are dangerous waters. There are market participants who make their money on pure latency arbitrage; it is a 100% speed game (because anyone can fi

Completely untrue. Pure speed games are "winner take most", and brutally difficult. It is very hard to win on speed.

Sure, you can get the point where you're placing trades for a couple hundred grand... as long as a lot of things fall into place for you. Writing your own apps? Unless you think you can get talent that is willing to roll the dice and poss

You make the assumption that they would trade. That assumption is only valid because of people like me . I don't need to justify my activity, nor do I want to go that route--my point is that the fact that participants can realistically ex

In current events conversations, participants can usefully be divided into "those who read the Economist", and "other." There isn't a better magazine, period. And I'm not a banker, or a Tory. I am just under 40 though.

I'm a total foodie, and I simply cannot read this book. I'm not sure if I need pretty pictures, or salacious kitchen anecdotes, or what, but I read a lot of food books and I've failed to get past pg. 30 on this one several times.

For a time, I considered this my bible. But it's too idealistic, and goes a long way on some fairly iffy assumptions. It's still compelling as hell, though.
