Famous for his work in math, astronomy, nuclear engineering, and theoretical physics, Freeman Dyson has left his mark on almost every scientific discipline. He's won countless awards, and written numerous books on a wide range of topics both scientific and philosophical. One of his biggest contributions to science was the unification of the three versions of quantum electrodynamics invented by Feynman, Schwinger and Tomonaga. 10 years after moving to the U.S. he started working on the Orion Project, which sought to create a spacecraft with a nuclear propulsion system. STNG exposed the idea of a Dyson sphere to the masses, and his hypothetical plan for making a comet habitable with the help of genetically-engineered plants is a personal favorite. Mr. Dyson has graciously agreed give us a bit of his time in order to answer your questions. As usual, ask as many as you'd like, but please, one question per post.

First time accepted submitter DW100 writes "Microsoft, Nokia and Oracle have taken it upon themselves to moan to the European Commission about Google's Android dominance, which they say is an underhand bid to control the entire mobile market. The firms are part of the FairSearch group, which has just filed a complaint that Google is using Android as a 'Trojan Horse' to take control of the mobile market and all the related advertising revenue. Microsoft would of course know all about this, being at the end of several similar anti-competitive complaints in the past."

KindMind writes "To probably no one's surprise, wiping a smartphone by standard methods doesn't get all the data erased. From an article at Wired: 'Problem is, even if you do everything right, there can still be lots of personal data left behind. Simply restoring a phone to its factory settings won't completely clear it of data. Even if you use the built-in tools to wipe it, when you go to sell your phone on Craigslist you may be selling all sorts of things along with it that are far more valuable — your name, birth date, Social Security number and home address, for example. ... [On a wiped iPhone 3G, mobile forensics specialist Lee Reiber] found a large amount of deleted personal data that he recovered because it had not been overwritten. He was able to find hundreds of phone numbers from a contacts database. Worse, he found a list of nearly every Wi-Fi and cellular access point the phone had ever come across — 68,390 Wi-Fi points and 61,202 cell sites. (This was the same location data tracking that landed Apple in a privacy flap a few years ago, and caused it to change its collection methods.) Even if the phone had never connected to any of the Wi-Fi access points, iOS was still logging them, and Reiber was able to grab them and piece together a trail of where the phone had been turned on.'"

First time accepted submitter bobthesungeek76036 writes "On March 26th, Larry Ellison and always with fashionable haircut John Fowler announced the new line of SPARC servers from Oracle. Touted as the fastest microprocessor in the world, they put up some impressive SPEC numbers against much more expensive (and older) IBM hardware. Is the industry still interested in SPARC or is it too late for Larry to regain the server market that Sun Microsystems had many moons ago?" El Reg has a pretty good overview of the new hardware; the T5 certainly looks interesting for highly threaded work loads (there's some massive SMT going on with 16 threads per core), but with Intel dominating for single-threaded performance and ARM-based servers becoming available squeezing them for massive multi-threading, is there really any hope in Oracle's efforts to stay in the hardware game?

OverTheGeicoE writes "TSA recently announced that it would remove all of Rapiscan's X-ray body scanners from airports by June. As part of this effort, it is trying to move a millimeter-wave body scanner from the Helena, Montana airport to replace an X-ray unit at a busier airport. Strangely enough, they have encountered resistance from the Helena's Airport Manager, Ron Mercer. Last Thursday, workers came to remove the machine, but were prevented from doing so by airport officials. Why? Perhaps Mercer agrees with Cindi Martin, airport director at Montana's Glacier Park International Airport airport, who called the scheduled removal of her airport's scanner 'a great disservice to the flying public' in part because it 'removed the need for the enhanced pat-down.'"

Don't yet have one of those million Raspberry Pis, but you're in the market for a tiny, cheap ARM computer? An anonymous reader writes with this snippet from geek.com: "VIA has decided it's time to update the APC (ARM PC) board with new components and the choice of two configurations. The new systems are called APC Rock and APC Paper. The hardware spec for both boards is exactly the same except for the fact the Rock ships with a VGA port whereas the Paper doesn't. The Rock also costs $20 less at $79, whereas the Paper is $99. The reason for the price difference is the fact that the Paper ships with a rather novel case whereas the Rock is a bare board. The Paper's case is made from recycled cardboard attached to an aluminum chassis to help with strength, meaning it will keep the dust off the components and make it easier to carry while keeping weight to a minimum."

sfcrazy writes "Mark Shuttleworth, the founder of Ubuntu, has shared his plans for 2013. It was clear from the Nexus 7 initiative that Ubuntu is eventually looking into the mobile space more seriously. Google created the cheap device Ubuntu was looking for wider testing and development. The initial builds of Ubuntu for Nexus 7 also showed that, despite popular perception, Unity is far from ready for the mobile devices. In fact quite a lot of 'controversial' technologies introduced in Unity don't fit on a mobile devices such as Global Menus or HUD. So there are many challenges for Mark — redesign Unity for mobile, which may upset users again, get Ubuntu app developers to redesign apps for Ubuntu mobile, get top developers to write apps for Ubuntu... Is it all feasible when companies like RIM or Microsoft are struggling or is Ubuntu becoming a 'me too' company which is not brining anything new to the table and is simply trying to claim a pie?" Shuttleworth also wants to do something or other with the cloud: "It’s also why we’ll push deeper into the cloud, making it even easier, faster and cost effective to scale out modern infrastructure on the cloud of your choice, or create clouds for your own consumption and commerce."
