Hugh Pickens writes "Using Netflix as a business model, Osman Rashid and Aayush Phumbhra founded Chegg, shorthand for 'chicken and egg,' to gather books from sellers at the end of a semester and renting — or sometimes selling — them to other students at the start of a new one. Chegg began renting books in 2007, before it owned any, so when an order came in, its employees would surf the Web to find a cheap copy. They would buy the book using Rashid's American Express card and have it shipped to the student. Eventually, Chegg automated the system. 'People thought we were crazy,' Rashid said. Now, as Chegg prepares for its third academic year in the textbook rental business, the business is growing rapidly. Jim Safka, a former chief executive of Match.com and Ask.com who was recently recruited to run Chegg, said the company's revenue in 2008 was more than $10 million, and this year, Chegg surpassed that in January alone."

Reader resistant sends in an update to our discussion a month back on the possibility of violent space weather destroying power grids worldwide during the upcoming solar cycle. Wired is running an interview with Lawrence Joseph, author of "Apocalypse 2012: A Scientific Investigation into Civilization's End," and John Kappenman, CEO of electromagnetic damage consulting company MetaTech. The piece brings two new threads to the discussion: the recently discovered presence of an unusually large hole in Earth's geomagnetic shield, magnifying our vulnerability, and possible steps we can take over the next few years to make the power grid more robust against solar flares and coronal mass ejections. There's also that whole Mayan 2012 thing. Quoting John Kapperman: "What we're proposing is to add some fairly small and inexpensive resistors in the transformers' ground connections. The addition of that little bit of resistance would significantly reduce the amount of the geomagnetically induced currents that flow into the grid. In its simplest form, it's something that might be made out of cast iron or stainless steel, about the size of a washing machine. ...we think it's do-able for $40,000 or less per resistor. That's less than what you pay for insurance for a transformer. [In the US] there are about 5,000 transformers to consider this for. ... We're talking about $150 million or so. It's pretty small in the grand scheme of things."

The FNP writes "Time Warner has postponed their plans to test tiered data caps in Greensboro NC, Rochester NY, San Antonio TX, and Austin TX. This announcement comes shortly after the media started reporting on Eric Massa's opposition and protests planned for this Saturday outside of Time Warner's offices in Greensboro and Rochester." There's also a good piece at Ars on the fall of the current tiered-pricing plans.

volume4 brings news that David Wood of the Symbian Foundation has made a post detailing their plans for a release schedule, with new versions due out every six months. We discussed Nokia's acquisition of Symbian for the purpose of open sourcing the popular mobile OS last year. Quoting: "There's a lot of activity underway, throughout the software development teams for all the different packages that make up the Symbian Platform. These packages are finding their way into platform releases. The plan is that there will be two platform releases each year. ... Symbian^2, which is based on S60 5.1, reaches a functionally complete state at the middle of this year, and should be hardened by the end of the year. This means that the first devices based on Symbian^2 could be reaching the market any time around the end of this year — depending on the integration plans, the level of customisation, and the design choices made by manufacturers. Symbian^3 follows on six months later — reaching a functionally complete state at the end of this year, and should be hardened by the middle of 2010."

afabbro writes "The US Supreme Court rejected the FTC's bid to impose anti-trust penalties on Rambus. Without comment, they let stand an appeals court decision favoring Rambus. The FTC had found that Rambus undermined competition by getting secretly patented technology included in industry standards, but the Supremes evidently didn't agree."

eldavojohn writes "You might remember the tiny news that Half Life 2 source code was leaked in 2003 ... it is the 6th most visited Slashdot story with over one kilocomment. Well, did anything happen to the source of the leak, the German hacker Axel 'Ago' Gembe? Wired is reporting he was offered a job interview so that Valve could get him into the US and bag him for charges. It's not the first time the FBI tried this trick: 'The same Seattle FBI office had successfully used an identical gambit in 2001, when they created a fake startup company called Invita, and lured two known Russian hackers to the US for a job interview, where they were arrested.'"
