You are far too generous -- there was a comment on this paper in the next issue of the journal entitled Tai's formula is the trapezoidal rule. There is nothing complicated or clever about it.
They are bad Lotto numbers -- it turns out that lots of people choose numbers with obvious patterns (series, pretty patterns on the selection forms, etc) like this so you'd be sharing any win with many. You are better to get a random number generator to choose you something "truly random".

The BPS research digest describes a paper that has studied user behaviour with a tool that records all mouse and keyboard activity while users complete a questionnaire. "The new tool revealed that 31 [of 1046] participants changed their reported age; 5.9 per cent made suspicious changes to opinions they'd given; 46 per cent clicked through at least some parts of the questionnaire at a suspiciously fast rate; 3.6 per cent of participants left the questionnaire inactive for long periods; 6.3 per cent displayed excessive clicking; and 11 per cent showed excessive mouse movements. Further information that could be used to verify the questionnaire answers showed that participants who'd displayed more suspicious behaviour while filling out the questionnaire also tended to provide answers that didn't match up with the other information source."
The article makes a comparison with other similarly skilled workers and historical levels of employment in the sector. 6% is high by these standards. And 6% is more like 1 in 17.

If you're a guy, bring attractive women—ideally younger women in designer clothes. Don't go with other dudes. And doormen are well versed in trendiness, so wear Coach, Prada, Gucci—but don't show up in a nice suit with DSW shoes.' No, Rivera doesn't write an advice column for the rich and the restless. But the Kellogg School of Management professor did go undercover to expose how people evaluate status in a glimpse. Specifically, she wanted to know how the meaty doormen positioned outside exclusive clubs—bouncers in nightlife language—determine who enters.

nk497 writes: While the world focuses on BP in the wake of the Gulf of Mexico spill, Nigeria continues to be plagued by a series of spills in the Niger delta — some of which are the responsibility of US firm ExxonMobil. Over the past 50 years, 10.5 million barrels have spilled in the area, five times that which has spilled in the gulf. On May 1, 25,000 barrels were spilled when an ExxonMobile pipeline erupted. It took seven days before the leak was stopped, with very little press coverage.
But the whole google search sidebar was ripped off from Bing and seems to be very successful. You'd be in far more trouble if you refused to consider an idea just because it came from a place you didn't like.
