- 2010-Jul-03: In the middle of a market correction on 6-May-2010 there was a tremendous spike down, initial reports were suggesting that a single miss-entered trade may have caused this event. Whatever the cause the noise from this is going to be heard around the markets of the world for some time. This event has become knows as the "Flash Crash" and is now thought to have been caused by delays in quote processing on the NYSE (see this analysis by Nanex, discussed here on Slashdot) perhaps intentionally caused by some party transmitting large numbers of quotes, very rapidly, in a sort of denial-of-service type attack. More discussion of this here [9108]

- 2010-Jan-08: Some articles on the Weibull distribution which can be used to model the probability of failure of devices. The significant difference between this and the normal distribution is that the Weibull is a one-sided curve, so all the events happen above a reference point rather than being distributed on either side of the reference point. This makes sense for things like time to failure given that a component cannot fail before it is put into use (well, if you include manufacturing defects and shipping issues it could...).

- The iPod International Currency Index, this artical confirms something I have suspected since the 1980's, that the British Pound is way over valued. In my trips to England from Canada I have always observed that when in Britain I "spend pounds just like I spend dollars back in Canada", so a person living in Britain must earn far more dollars to have the same standard of living as a Canadian (or American). When relatives from Britain have come to visit they have the reverse impression, they are always amazed at how far their pounds go when spent in Canada. The classic example of this (though largely a tax artifact) is that the price of gasoline in the UK (in pounds) is the same as in Canada (in dollars) - and this has held true since about 1977! [6124]
