Venture Capitalists Bet LinkedIn Worth US$1 Billion

Four venture capital firms are betting internet startup LinkedIn is worth $US1 billion, highlighting the lofty hopes riding on online services that connect people with their friends, family and business associates. The 10-figure valuation is implied by a $US53 million investment being announced on Wednesday from Bain Capital Ventures, Sequoia Capital, Greylock Partners and Bessemer Venture Partner

Do Women Write Better Code?

We all know men hate to ask for directions. Apparently they loathe putting directions in computer code, too. Emma McGrattan, the senior vice-president of engineering for computer-database company Ingres-and one of Silicon Valley’s highest-ranking female programmers-insists that men and women write code differently. Women are more considerate of those who will use the code later. They’ll intersperse their code-those strings of instructions that result in nifty applications and programs-with helpful comments and directions, explaining why they wrote the lines the way they did and exactly how they did it. Men, on the other hand, have no such pretenses. Often, they try to obfuscate things in the code

eBay to Let Outside Software Work Inside its Site

eBay has unveiled plans to let outside software programs work inside the world’s largest e-commerce site, joining a trend toward openness that fuelled the popularity of the social network website Facebook. At the online auction leader’s annual conference for software developers in Chicago, eBay is laying out Project Echo, a plan to give independent developers a path to having their software featured within eBay’s core site

Amazon Plays Rough in Disputes with Publishers

Amazon, the online retailing giant with a fast-rising share of the consumer book market, has adopted the literary equivalent of a nuclear option for rebellious publishers who balk at its demands. In the latest in a series of disputes over the division of revenue from online sales, Amazon has disabled the buy now with 1 click icon on its British Web site for hundreds of books published by Hachette Livre UK

A Trio of Super-Earths

Using the HARPS instrument at the ESO La Silla Observatory, they have found a triple system of super-Earths around the star HD 40307. Looking at their entire sample studied with HARPS, the astronomers count a total of 45 candidate planets with a mass below 30 Earth masses and an orbital period shorter than 50 days. This implies that one solar-like star out of three harbours such planets

Regenerating Lost Cartilage

The key to coaxing cells to regenerate might be to make things a little rough for them. Thomas Webster, a bioengineer at Brown University, has been developing implantable materials with nanoscale textures to mimic the roughness of living tissues. Now, his team has found that cartilage cells can adhere to and grow more densely on a surface covered with carbon nanotubes, particularly when they are also exposed to electrical stimulation. Webster believes that surfaces incorporating carbon nanotubes, which are not only textured but are also electrically conductive, could be a promising strategy for designing cartilage implants

Google and Yahoo to Partner on IM

Most of the attention to the recent Google/Yahoo partnership has focused on the two companies’ search advertising plans, but the deal has implications for instant messaging, too. Yahoo and Google have agreed to enable interoperability between their respective instant messaging services. So far, exactly what that means is anyone’s guess. But the IM market could certainly benefit from a little more interoperability. Despite the fact that IM use is on the rise among home users and businesses alike, each separate IM network remains a walled garden, independent of all the others. Getting them to work together — similar to how e-mail works — would benefit everyone

Scientists Find Bugs that Eat Waste and Excrete Petrol

Silicon Valley is experimenting with bacteria that have been genetically altered to provide renewable petroleum. For fermentation to take place you need raw material, or feedstock, as it is known in the biofuels industry. Anything will do as long as it can be broken down into sugars, with the byproduct ideally burnt to produce electricity to run the plant. The company is not interested in using corn as feedstock, given the much-publicised problems created by using food crops for fuel, such as the tortilla inflation that recently caused food riots in Mexico City. Instead, different types of agricultural waste will be used according to whatever makes sense for the local climate and economy: wheat straw in California, for example, or woodchips in the South

MPAA Wants to Stop DVRs from Recording Some Movies

At the request of theatrical film makers, the FCC on Friday quietly launched a proceeding on whether to let video program distributors remotely block consumers from recording recently released movies on their DVRs. The technology that does this is called Selectable Output Control, but the FCC restricts its use. The MPAA wants a waiver on that restriction in the case of high-definition movies broadcast prior to their release as DVDs

Not all USB Drives are Created Equal

Most USB 2.0 flash drives look the same, but that doesn’t mean they perform the same. Differences in the type of memory and, to a lesser extent, the type of I/O controllers used by USB drives can make one device perform two or three times faster and last (theoretically, at least) 10 times longer than another, even if both sport the USB 2.0 logo. Unfortunately for the average user, there are no accepted industry standards or certifications to judge what’s inside a USB 2.0 flash drive on a store shelf. Without checking reviews or running benchmarks, the only rule of thumb is that the more expensive drives (and those which post performance numbers on the packaging) will tend to be the fastest and, perhaps, last the longest

Mod Chips Legal in the UK

An appeals court has overturned a lower court ruling and has now said that mod chips do not violate copyright laws. The case involved a mod chip seller, who imported mod chips for the XBox from Hong Kong and would sell the chips or mod the Xbox’s himself. He was charged with copyright infringement and found guilty by a lower court. The appeals court has dismissed all charges, however — via Slashdot
