Dunwich Beach Sutterstock A professor of physical geography has put together the most detailed map yet of the sunken medieval town of Dunwich using underwater acoustic imagining. The port town, often referred to as “the British Atlantis,” was a hub of activity up until its collapse in the 1400s. This was brought about after a series of epic storms battered the coastline in the 1200s and 1300s, causing repeated flooding, submerging parts of the town, and flooding the harbor and river with silt. Today it stands as a small village, but up until its demise it was around the same size as medieval London. Despite still existing at depths of just three to 10 meters (or, 9.8 ft to 32.8 ft) below sea level, the murky conditions have made investigating what lies beneath particularly tricky. Since 2010, however, Southampton’s David Sear—along with the GeoData Institute, the National Oceanography Center, Wessex Archaeology, and local divers from North Sea Recovery and Learn Scuba—has been exploring the muddy depths using dual-frequency identification sonar (DIDSON) acoustic imaging.

The British ‘Atlantis’ is mapped in detail
bennyboy64 writes “An Australian university appears to be excelling at cultivating some of Australia’s best computer hackers. Following the University of NSW’s students recently placing first, second and third in a hacking war game (the first place winners also won first place last year), The Sydney Morning Herald reports on what exactly about the NSW institution is breeding some of Australia’s best hackers. It finds that a lecturer and mentor to the students with controversial views on responsible disclosure appears to the be the reason for their success.” Read more of this story at Slashdot. 
Apple apparently has the power to decrypt iPhone storage in response to law-enforcement requests, though they won’t say how. Google can remotely “reset the password” for a phone for cops, too: Last year, leaked training materials prepared by the Sacramento sheriff’s office included a form that would require Apple to “assist law enforcement agents” with “bypassing the cell phone user’s passcode so that the agents may search the iPhone.” Google takes a more privacy-protective approach: it “resets the password and further provides the reset password to law enforcement,” the materials say, which has the side effect of notifying the user that his or her cell phone has been compromised. Ginger Colbrun, ATF’s public affairs chief, told CNET that “ATF cannot discuss specifics of ongoing investigations or litigation. ATF follows federal law and DOJ/department-wide policy on access to all communication devices.” …The ATF’s Maynard said in an affidavit for the Kentucky case that Apple “has the capabilities to bypass the security software” and “download the contents of the phone to an external memory device.” Chang, the Apple legal specialist, told him that “once the Apple analyst bypasses the passcode, the data will be downloaded onto a USB external drive” and delivered to the ATF. It’s not clear whether that means Apple has created a backdoor for police — which has been the topic of speculation in the past — whether the company has custom hardware that’s faster at decryption, or whether it simply is more skilled at using the same procedures available to the government. Apple declined to discuss its law enforcement policies when contacted this week by CNET. It’s not clear to me from the above whether Google “resetting the password” for Android devices merely bypasses the lock-screen or actually decrypts the mass storage on the phone if it has been encrypted. I also wonder if the “decryption” Apple undertakes relies on people habitually using short passwords for their phones — the alternative being a lot of screen-typing in order to place a call.

Astronaut Chris Hadfield — the tweeting , tumbling Canadian astronaut who’s a one-dude astro-ambassador from the space programme to the Internet — has produced and released a video of his own performance of David Bowie’s “Space Oddity” (AKA the “Major Tom song”) on the ISS. He adapts the lyrics a bit to his own situation — and changes out the whole dying-in-space chorous — but is otherwise pretty faithful. From the credits, it appears that David Bowie gave permission for this, though that’s not entirely clear. I would think that not even a major record label would be hamfisted and cack-handed enough to send a takedown notice over this one (it’s been suggested for Boing Boing more than any other link in my memory), but I’m prepared to be surprised.
