silverpig writes "Cisco has released a whitepaper on mobile data usage which has some interesting data in it. The top 1% of users consume 20% of the bandwidth, but that share is down from 30% previously. 'Regular' users are catching up as they watch more video. High-bandwidth users of today will be relatively average users by 2015, so network operators should look to those users for insight in designing their future networks."

peter.hill.1980 writes "Wall Street's money making formulas need to be as explicit as possible for efficiency purposes. An old, existing and famous formula — binomial options pricing formula — has now been scrutinized for theoretical optimality in a forthcoming paper by Evangelos Georgiadis of MIT using Gosper's Algorithm, proving that no general explicit or closed form expression exists for pricing."

Muad writes "Maik Schmidt is our guide in the Pragmatic Bookshelf's venture into the world of electronics. This is a compact work, like all others in the series, it goes straight to applicable examples and makes you get your hands dirty with real work. The Arduino platform has been described in many ways, but the best I have heard so far insightfully labels it 'The 555 of the future,' referring to the ubiquitous timer chip so many simple electronic projects make use of. If you haven't been hiding under a rock for the past few years, you have doubtlessly seen the plethora of material on the subject that's out there: even O'Reilly, which usually does not ship multiple titles on a single subject, has a variety of them. Most of these works are rather similar, the ones I prefer are Massimo Banzi's Getting Started with Arduino (O'Reilly, 2008), by one of the original developers of the platform, and the strongly related Getting started with Processing by Casey Reas and Ben Fry. These are brief books in the 100-page range, not exhaustive works, but covering the core philosophy and basic operation of the tools is sometimes the best way to jump into a new subject.

Some days are better than others, and on those bad days we can have a tough time thinking rationally. While there are ways to beat a bad day, when you feel bad you can often feel like a completely different person. If you just can't shake those bad feelings, treat it as an opportunity. Study your behavior, keep track of what helps you out, and write it all down in a personal handbook that you can reference in the future. More »

gamricstone writes "Scientists have produced the world's most powerful optical microscope, which could help understand the causes of many viruses and diseases. Previously, the standard optical microscope can only see items around one micrometre — 0.001 millimetres — clearly. But now, by combining an optical microscope with a transparent microsphere, dubbed the 'microsphere nanoscope', the Manchester researchers can see 20 times smaller — 50 nanometres ((5 x 10-8m) — under normal lights. This is beyond the theoretical limit of optical microscopy. 'Seeing inside a cell directly without dying and seeing living viruses directly could revolutionize the way cells are studied and allow us to examine closely viruses and biomedicine for the first time.'"
