>we have seen bizarrely correlated asset price changes due to macro issues Actually, this is quite expected given event-risk in the market. For example, even in a non-crisis situation, correlation increases in intra-day trading when m

Firstly, nice effort. Secondly, some features you could add: 1. Constrained optimization - including budget constraints, sector selection constraints etc. A tough one would be cardinal constraints e.g. I am limited to 4 stocks etc. 2. Retur

"If you buy on the timescale of days to weeks, you can completely ignore HFT" Not if you have to deal with intra-day margin calls or stop losses. The trouble with most HFT-based algos is that most of them rely on a set of common signals (re

I agree politics is a very important part of our society and people should be interested in it. But technology is a means to solve problems whether they're presented by the struggle of humans to make their life better against the elements -

Really? You've to resort to name-calling rather than provide a logical argument as to why my statements would be wrong? Would you have called me a dumbass if we'd have met in real-life? Or would you have been more civil? Should I assume thi

I can still write software, discuss ideas and think about architecture etc etc. while totally ignoring both of those guys.

I'm seriously suggesting the underlying technology has nothing to do with politics. One can discuss buffer overruns and CSRFs and what not without any political overtones whatsoever (or should be able to). There is no area of human life tha

My statement still holds: the lowest quote is part of the problem. (And to answer your question: nope - and I hope not to).

"...and technological choices are politically influenced" Nope. Technological choices are solely influenced by the problem one is trying to solve. The course of war, peace and espionage may be determined by politics but the choice of techno

"But there’s no evidence that being able to prove (x² + y²)² = (x² - y²)² + (2xy)² leads to more credible political opinions or social analysis" Nothing else leads to that either. Political opinions and social analysis have zilch value in u

Your are confusing Math versus Applied Math. We take what we want to use in the study of engineering, physics, economics, finance and political science - pure Math develops those tools and they're highly useful. Is Math of a college level n

It's not being nit-picky - the opening ceremony is quite a massive bit of any Olympics. As one of the Athens 2004 organizers said, a 400m race in Sydney, Beijing, Greece or Atlanta would look exactly the same - it's the opening ceremony tha

I would be interested to know how long that main column of lightning persists - and what determines that time.

Well, the caste system exists and the inequalities exist - but they exist purely due to economic and political incentives. Belief in karma and reincarnation has got nothing to do with it. And even the victims of this system know this.

Well, that perception, if it has been presented to you, is false. In fact, in India, whenever someone is discouraged to help someone out, the most popular argument is "Why bother? It's not your problem!" or "It'll be more trouble than it's

The mistake the author made is that he lived in India for three weeks. Had he stayed for six months or a year, he'd have been able to figure out what makes India tick - India is the very embodiment of clever innovation to survive - it wil

Singapore is a different sort of "emerging-market", to be honest - it's economy has historically been far too open (and too small) to disallow that sort of thing from happening. A similar theme applies to South Korea - which probably has th

Central banks do funnel money into the real economy via their monetary policy (Congress can only provide fiscal stimulus). And lack of liquidity to the extent that it prevents current liabilities to be serviced causes insolvency - something

by photon137 14y ago
I agree with every single point you've made except for the third (ie about central banks). Central banks need to act as the "lender of last resort" - however, what needs to be fixed is the transmission mechanism - so that the emergency loan

This is on the front-page of HN because, as Richard Feynman said, "It's the things that nobody knows about that we can discuss. We can talk about the weather; we can talk about social problems; we can talk about psychology; we can talk ab

Eh? By Phone I suppose you meant Windows Phone? And Xbox runs the NT kernel for sure (though no way to confirm that).

remind me what happened to the guy in the photo in Tianenmen Sq, standing in front of the tank He became a legend. Dissenters in China have that image burnt firmly in their mind regardless of however hard the government tries to erase it.

Your fundamental premise is wrong (as an aside, fiat currency does pay dividend - it's called "interest"). Central Banks are meant to be independent of the government. Their mandates are: (a) Acting as a lender of last resort to banks (b) C

You are confusing business analysts from management consultancies like McKinsey/BCG/Bain (or CEO-reporting groups like the SPG at American Express) with software BA/PMS (the people under discussion here). Software BA/PMs have nothing to do

"A BAs/PMs can reach the conclusion that a private label implementation (or 3 of them, with some outsourced integration work outsourced to competent integrators) is a much better solution, whereas a programmer (with any ingrained survival i

I'll counter that - even not-so smart programmers with enormous egos would be able to ship something clunky, partly broken, not feature-perfect etc. (case in point: Linux - do you think they required full-time BAs to manage this very nicely
