The article is so vague it seems even the author isn't particularly sure of the point. Notions of factor models and hidden markov models have been around in the statistics literature for ages. Computer science's contribution to the discuss

The opinion piece you're looking for would be suited for, perhaps, 'Autistics Monthy'. People who read WSJ don't expect to have to tweet about the latest LOLCat (or haskell framework or whatever) to get your attention. I can see it now: "Th

This is nonsense - I know people in quant funds who have tried to do things like this. All the boring stuff that Google doesn't care about, like SEC filings and Quarterly Reports, matter far more than aggregate attention. I'm sorry but

It's worth noting that hn doesn't aspire to profitability via advertising - pg doesn't have to worry about things like "stickiness" and "reach". So yes - hn is a great service to the community.

Language is another huge barrier to trade, especially in labor markets. In an alternate, culture-less dimension this problem is solvable by having high skilled workers move to Germany and low skilled workers move to Greece.

This is misguided: there is a definite cost/benefit tradeoff in having a common currency. Common currency means no independent central banks, which could use monetary policy to devalue independent currency and stimulate exports. Not havin

I'm with Tyler Cowen on applied Keynesianism ( http://www.marginalrevolution.com/marginalrevolution/2010/05... ) - sure it can work but it's a political quagmire on the national level. Now take that to the international level of the Euro,

Great summary - I'm with you right up to the point where you think less monetary freedom is actually good because it will force the Eurozone to "tighten its belt". Miracles do happen, but just consider the political animosity already bubbl

Yes: economically we also need ditch diggers in more numbers than classic literature experts. That doesn't make society better off if all the top universities start funneling money into ditch digging just because they can get away with it.

I am not discounting the application of "poetic" solutions, certainly there are cases where this is a justified approach. E.g. I think this is particularly relevent in regards to parallelization. There's a time for poetry and a time for pr

Not a lot of it is statistical arbitrage - yes this is what Rennaisance and D.E. Shaw do, but this is not what banks (sans perhaps Goldman Sachs) devote much of their compute power to. It's just too hard to make money doing this compared t

I think OP's point is that enjoying the simple prose of programming, reveling in what you can accomplish with simple tools and techniques, is another equally valid route to enjoyment. It's hard for me to disentangle pg's "blub" epithet from

Tim Bray is obviously an extremely smart man, but I think he's misguided on this. Sure we all need to look inwards from time to time, but many of us already do that. Maybe they did just "draw the short straw", but that doesn't exonerate th

Strongly agreed. In some senses, the intermingling of science/engineering is/was due to strong economic forces that placed such a high value on software engineering. As of 10 years ago, the world needed more software engineers than it had

Engineering aggregates known solutions to solve specific problems. Science clarifies questions worth asking. There is a difference.

Seeing shorting as "making a bet against a company" is an accurate, but overly simplistic view of modern financial theory. Say I want to buy a stock index that includes BP, but don't want to expose myself to their current volatility. I cou

Yes - as I mentioned regardless of quants there will always be heavy demand for mathematically-minded developers in finance. As far as enterprise development goes, it's a great (well funded) industry to work in. Technologies tend to focus

Also on a more practical note: take note of high-frequency data costs. FX is the only asset class you can study in detail without major financial backing because of the costs. This seems to happen even in academia: research in CDS's seemed

Congrats for your newfound love and condolences for your grandfather. Tread carefully - intellectualizing love is existentially rocky territory. I have worked in algorithmic trading, hedge funds, and investment banking. I have degrees in
