Comment Hope? (Score 1) 674

Great news! I really hope the 18-30 year olds can still make a difference in an ageing society like Europe. I'm concerned that some decades ago, when the median age was much lower, western democracies were more agile and creative (look for example at the hippies, I'm not sure if that still wouldn't be possible).

Submission + - Future of Financial Mathematics? 1

An anonymous reader writes: Nassim Nicholas Taleb, a famous "Quant" has long been a strong critic of the use of mathematics and statistics in the financial markets. He has been very vocal in his books The Black Swan and Fooled by Randomness. In his article on edge.org, he says "My outrage is aimed at the scientist-charlatan putting society at risk using statistical methods. This is similar to iatrogenics, the study of the doctor putting the patient at risk." After the recent financial crisis, wired.com ran an article titled "Recipe for Disaster: The Formula That Killed Wall Street" in which the quant David Li and his Gaussian Copula were crucified.

I recently got admitted to a reputed graduate program in Computational & Applied Mathematics. There is a wide range of subjects in which you can pursue your PhD, one of them being Financial Mathematics, in which I had a passing interest for quite some time. In the current scenario, how advisable it is to pursue a PhD in a topic as specialized as Financial Mathematics? What would my options be five years down the line? Will the so-called "quants" would still be wanted by the banks and other financial institutions or would they turn to more "non-math" approaches? Would I be better off in specializing in 'traditional' and less volatile areas of Applied Mathematics? In short, what is the future of Financial Mathematics in hindsight of the current financial crisis?

Submission + - The Pirate Bay Aftermath Circus in Swedish Press

MaulerOfEmotards writes: Reading the Swedish news reports, the turmoil surrounding the aftermath of The Pirate Bay trial continues.

Part of the news are occupied with Tomas Norström, the presiding judge of The Pirate Bay trial. Mr. Nordström is suspected of bias after reports of affiliation with copyright protection organisations, for which he has been charged reported to the appeals court, is rapidly gaining a certain notoriety. The circus around him is currently focused on three points. First, his personal affiliation with at least four copyright protection organisations, a state the potential bias of which he himself fails to see and refuse to admit. Secondly, Swedish trials use a system of several lay assessors to supervise the presiding judge, one of which, a member of an artists' interest organisation, which is far fewer than Mr. Norström himself, was by Mr. Norström made to resign from the trial for potential bias, and his failing to see the obvious contradiction in this casts doubts on his suitability and competence. Thirdly, according to professor of judicial sociology Håkan Hydén the judge has inappropriately "duped and influenced the lay assessors" during the trial: "a judge that has decided that 'this is something we can't allow' has little problem finding legal arguments that are difficult for assisting lay assessors to counter".

The apparent grave legal problems if the trial itself is also of medial interest. Professor Hydén continues with enumerating "at least three strange things" with "a strange trial": Firstly that someone can be sentenced for being accessory to a crime for which there is no main culprit: "this assumes someone else having committed the crime, and no such individual exists here ... the system cannot charge the real culprits or it would collapse in its entirety". It is unprecedented in Swedish judicial history to sentence only an accessory. Secondly, that the accessories should pay the fine for a crime committed by the main culprits "which causes the law to contradict itself". And thirdly that accessories cannot be sentenced to harsher than the main culprit, which means that every downloader must be sentenced to a year's confinement. In closing Me. Hydén sums up by saying that to allow this kind of judgement the Swedish Parliament must first pass a bill making this kind of services illegal, which hasn't been done.

Submission + - Microsoft's Sales Drops, First Time in 23 Years (cnn.com) 1

RadiusK writes:

CNN reports that Microsoft Corp. reported quarterly sales that fell for the first time in its 23-year history as a public company. The company has had a difficult time combating slumping demand for its Windows operating system, as the economic slowdown has dragged PC sales down 7% to 9%, according to Microsoft's estimates. The recession has also prompted many consumers to opt for cheaper, scaled-down "netbooks". They typically run a lower-cost version of Windows or an open-source operating system such as Linux.

This is quite a remarkable statement, and you will have to do both of the following for me to be convinced:

I think a can do that for point 1, but not for point 2:

1. Back up your claim with evidence showing that a company would be able to maintain customers despite inflated prices.

If you define 'inflated' as any price level above the level we would have under perfect competition, then this is easy to show:
Many products are sold at different prices in different countries simply because the people in one country have more purchasing power than in the other country. Under perfect competition, this isn't possible. One of the reason there often isn't perfect competition are government granted privileges like patents. So if I want to buy some patent-protected drug, it will often cost me twice as much as in a neighbor country. In a free market, people could start going to the neighbor country and import truckloads of these products, thereby driving the domestic prices down. However, this is forbidden here.

2. Show that the ends justify the means - that it is alright to violate the individual rights of the members of a company to offer their property - their product - at a price they decide, and be held responsible for their actions in the success or failure of those prices.

I'm not sure this is possible to show. It depends on being able to put a number on the effect described in (1). I guess that products in my country (Switzerland) are generally about 10% overpriced, when comparing to Germany, even when taking into account higher wages. Furthermore, this depends on how high you value property rights. This is highly ideological and I could be discussed endlessly. That's why I don't think I can show (2). It's a matter of personal values and ideology.

In any other situation, losing the freedom of action over your property is grounds for police intervention against the perpetrator. What is different here?

One important difference here is that the inflated prices is often only possible because of government granted privileges like patents. In such cases, I don't think we should be too scrupulous in taking something back in return.

A law that forbids price fixing leads to lower prices for the consumer as it allows different vendors of a product to compete against each other. However, this also means that the producer looses some of its control over his products.
Most European countries consider this a small price to pay to get the lower prices. Especially if the profits of overpricing go abroad anyway. :)

Enforcing braces is a good idea, I've seen the following class of mistakes too often:

if (condition)
    statement

is changed to

if (condition)
    log("doing x")
    statement

which obviously brakes the code. If you don't like the braces, you can often use ? and : instead.
