farnsworth writes "Tony Alfrey has put together a fascinating page with some history, analysis, and possible explanations for what ultimately went wrong with the recent emergency repair of the San Francisco-Oakland Bay Bridge. The bridge has been closed for days and is not scheduled to open for days to come, hugely inconveniencing more than 250,000 people a day. His analysis touches on possibly poor welding, a possibly flawed temporary fix, and the absence of a long-term fix or adequate follow-up by Caltrans, the agency responsible for the bridge. Slashdot is a great engineering community; what other insights do you have on the bridge situation?"

siddesu writes with disappointing news to anyone who'd like to see solid-state storage dominate in the near-term future. "A new study of storage technology by the former CTO of Seagate predicts that hard disks will remain the cheapest storage technology in the next decade and probably beyond."

theodp writes "It was the best of operating systems, it was the worst of operating systems. When it comes to the merits of Windows 7, it looks like Slate's Farhad Manjoo and PC Magazine's John Dvorak are going to have to agree to disagree. Manjoo gives Windows 7 a big thumbs-up (a sincere one, unlike Linus!), calling it a 'crowning achievement,' while Dvorak is less than impressed, saying, 'Win 7 is really just a Vista martini. The operating system may have two olives instead of one this time out, but it's still made with the same cheap Microsoft vodka.' So, for those of you who've had a chance to check things out, are things really different this time?" Multiple readers have also pointed out that there have been problems with the download and installation of Windows 7 upgrades obtained through the student discount offer, which Microsoft has confirmed.

Aristos Mazer sends word of research out of iRobot on a "chembot," or morphing blob robot, that looks like dough and moves by shifting its sides from solid-like to liquid-like states. This will allow it, in theory and after lots of refinement, to pass through cracks by squeezing. iRobot calls the new technique "jamming." The research project was funded by DARPA. The video clearly shows the early stage the work is in, but when you think about it the possibilities are a little unsettling.

misnohmer writes "Verizon has just launched a new set of ads confirming the rumors of its upcoming iPhone competitor: 'Unlike previous Android phones, the Droid is rumored to be powered by the TI OMAP3430, the same core that the iPhone and Palm Pre use, and which significantly outperforms Qualcomm 528MHz ARM11-based Android phones that exist today. Droid will also be running v.2.0 of Android, with a significantly upgraded user interface. The Droid poses a different and more significant challenge to the iPhone than any other phone to date. The Palm Pre could have been that challenger, but it lacked the Verizon network, and users were unimpressed with the hardware. According to people who've handled the device, the Droid is the most sophisticated mobile device to hit the market to date from a hardware standpoint. When you combine that with the Verizon network, you've got something that is most definitely a challenger to the Jesus phone.'"

bonch writes "Apple's Grand Central Dispatch, which was recently open sourced, has been ported to FreeBSD and is planned to be included by default in FreeBSD 8.1. Also known as libdispatch, the API allows the use of function-based callbacks but will also support blocks if built using FreeBSD's clang compiler package. There's already discussion of modifying BSD's system tools to use the new technology." The port was originally unveiled last month at the 2009 Developer Summit in Cambridge. Slides from that presentation are available via the Dev Summit wiki.

An anonymous reader tips news that Blizzard will be requiring all World of Warcraft players to use Battle.net accounts to log into the game starting on November 11th. After that time, players who don't switch will be unable to play the game. Some time after the transition is complete, players will be able to "participate in cross-realm chat in World of Warcraft, create real-life friends lists, and communicate across different games." More details on the new Battle.net and what it will do are available in our Blizzcon wrap-up and interviews from August. Naturally, the idea that the new Battle.net is getting closer to deployment has sparked speculation that the StarCraft II beta might come along soon.

areYouAHypnotist writes to tell us the New York Times has the scoop on a new comic book about the quest for logical certainty in mathematics. "The story spans the decades from the late 19th century to World War II, a period when the nature of mathematical truth was being furiously debated. The stellar cast, headed up by Bertrand Russell, includes the greatest philosophers, logicians and mathematicians of the era, along with sundry wives and mistresses, plus a couple of homicidal maniacs, an apocryphal barber, and Adolf Hitler."

itwbennett writes "Sony announced Friday that it has developed a prototype power system based on magnetic resonance that can send 'a conventional 100 volt electricity supply over a distance of 50 centimeters to power a 22-inch LCD television.' Unfortunately, Sony's prototype wasted 1/5 of the power fed into it and additional losses 'occurred in circuitry connected to the secondary coil so the original 80 watts of power was cut by roughly a quarter to 60 watts once it had made its way through the system.'"

CWmike writes to mention that IBM has launched LotusLive iNotes, a system designed to compete with GMail and Exchange that offers email, calendaring, and contact management. "Pricing starts at $3 per user per month, undercutting Google Apps Premier Edition, which costs $50 per user per year. IBM is aiming the software at large enterprises that want to migrate an on-premise e-mail system to SaaS (software as a service), particularly for users who aren't tied to a desk, such as retail workers. It is also hoping to win business from smaller companies interested in on-demand software but with concerns about security and service outages, such as those suffered by Gmail in recent months. LotusLive iNotes is based on technology IBM purchased from the Hong Kong company Outblaze."

An anonymous reader writes "'Linux vendor Red Hat, and 17 other vendors, have protested a Swiss government contract given to Microsoft without any public bidding. The move exposes a wider Microsoft monopoly that European governments accept, despite their lip service for open source, according to commentators. The Red Hat group has asked a Swiss federal court to overturn a three-year contract issued to Microsoft by the Swiss Federal Bureau for Building and Logistics, to provide Windows desktops and applications, with support and maintenance, for 14M Swiss francs (£8M; $15M) each year. The contract, for 'standardized workstations,' was issued with no public bidding process, Red Hat's legal team reports in a blog — because the Swiss agency asserted there was no sufficient alternative to Microsoft products.'"
