McGruber writes "Walt Mossberg, principal technology columnist for The Wall Street Journal, has written his last column after 22 years of reviewing consumer technology products for the newspaper. His final column discusses the dozen personal-technology products that were most influential over the past two decades."

mschaffer noted a Bloomberg piece saying "US regulators said Verizon Communications Inc.'s networks may have dropped a 'truly alarming' number of wireless emergency calls during a snow storm last month, and asked the carrier to investigate." The article says 10,000 calls failed to connect during one blizzard. Can't wait to see what all those AT&T migrators think.

An anonymous reader writes "This year we've seen molten salt power plants start to pick up steam around the world, and now the technology is heating up stateside — California just approved its first molten salt energy plant. Designed by SolarReserve, the plant uses heliostats to focus thermal energy on a power tower filled with salt, which is able to reach very high temperatures (over 1000 degrees Fahrenheit) and can hold heat for an extraordinary length of time. Heat from this reserve of molten salt can then be pumped through a steam generator to provide on-demand energy long after the sun has set."

DMandPenfold writes "Advanced modeling software analyzed the cementing conditions for BP's Deepwater Horizon oil well as unstable, days before the blast that killed 11 oil rig workers and let millions of barrels of oil spill into the Gulf of Mexico. Halliburton, the company that carried out the cement job, used its own modeling software called OptiCem, to support arguments that more stability was needed for the piping and cement. ... An OptiCem test on 15 April, five days before the blast, stipulated that from Halliburton’s point of view, 21 ‘centralizers’ needed to be added to the well bore. The centralizers are used to provide space around the oil pipe casing within the well, as cement is poured around it, and are a vital part of safe drilling. BP initially adhered to the OptiCem software test and ordered 15 extra centralizers. But when technicians on the rig received the extra centralizers they mistakenly decided the new centralizers were the incorrect type. At this point BP proceeded with the drilling anyway, with the six centralizers, deciding another known technique of injecting cement in other places would work."

Mike Zahalan writes with an update to last month's news that AOL and various private equity firms were exploring the possiblity of buying Yahoo. While talks between the companies have not officially gone much deeper, AOL has now hired financial advisers to analyze their options. Still, Kara Swisher writes at All Things Digital that the complexity of a deal between the two companies will be the biggest obstacle they have to overcome. "Among the issues being grappled with: Onerous tax implications around a variety of deals; a need for complete cooperation from too many players; and the realization that a hookup of AOL and Yahoo might cause more problems than it solves. 'It looks great conceptually and everyone gets all hot and bothered,' said one prominent investor who did his own strategizing about Yahoo and AOL. 'But when you actually do the numbers, you hit a pretty big wall of impossible.'"

digitaldc writes with this quote from PCWorld: "It kills me to say this: The dream of Linux as a major desktop OS is now pretty much dead. Despite phenomenal security and stability — and amazing strides in usability, performance, and compatibility — Linux simply isn't catching on with desktop users. And if there ever was a chance for desktop Linux to succeed, that ship has long since sunk. ... Ultimately, Linux is doomed on the desktop because of a critical lack of content. And that lack of content owes its existence to two key factors: the fragmentation of the Linux platform, and the fierce ideology of the open-source community at large."

Hugh Pickens writes "Alexis Madrigal has an interesting essay in the Atlantic about the popular response of people in the 19th century to the development of the electric power industry in America. Before electricity, basically every factory had to run a bit like a Rube Goldberg machine, transmitting power from a water wheel or a steam engine to the machines of a manufactory but with the development of electric turbines and motors the public believed engineers were tapping mysterious, invisible forces with almost supernatural powers for mischief. 'Think about it,' writes Madrigal. 'You've got a wire and you've got a magnet. Switch on the current — which you can't see and have no intuitive way to know exists — and suddenly the wire begins to rotate around the magnet. You can reverse the process, too. Rotate the magnet around the wire and it generates a current that can be turned into light, heat, or power.' And that brings us back to Rube Goldberg, a cartoonist who was was shockingly popular in his heyday and whose popularity closely parallels the rise of electrification in America. 'I think Goldberg's drawings reminded his contemporaries of a time when they could understand the world's industrial processes just by looking. No matter how absurd his work was, anyone could trace the reactions involved,' writes Madrigal. 'People like to complain that they can't understand modern cars because of all the fancy parts and electronic doo-dads in them now, but we lost that ability for most things long ago.'"

andylim writes "Just when you thought it was safe to dev a fart app for a BlackBerry, RIM's VP of platform product management, Alan Panezic, is making it clear that that's not want RIM is looking for. 'We don't need 200 fart apps in App World. Those are apps you'll use three or four times then never open again. You're not looking at ads, clicking on ads or buying premium upgrades, and the app isn't adding any value to your device.' Turns out RIM wants 'SuperApps', ones that keep you coming back for more because they add something to your life — be it ongoing entertainment value or doing something for you. Most importantly for developers, these are the apps that will garner the most revenue; whether it comes from premium upgrades, in-app advertising, or additional-cost content."

eldavojohn writes "Media darling Julian Assange, founder of Wikileaks, has been told by his lawyers to avoid the United States on the grounds that the US military would like to ask him a few questions about his source of the Collateral Murder video. Assange claims to be holding yet more video (of a US attack on a village that allegedly killed 140 civilians in May of 2009), as well as a quarter million sensitive cables relating to the current foreign war operations from the US State Department. Assange surfaced for the cameras in Brussels while speaking about the need for the freedom of information. Can he build a high enough profile to protect himself from danger?"
