How Cubism Protected Warships in World War I

AUTHOR: MARTY GRAHAM MARTY GRAHAM BACKCHANNEL 11.29.17 06:55 AM HOW CUBISM PROTECTED WARSHIPS IN WORLD WAR I COURTESY OF NIK HAFERMAAS FOR UEBERALL INTERNATIONAL If you’re stuck in traffic along the I-5 near San Diego International Airport, and your attention wanders from the brake lights in front of you, your eyes might land on a low-slung leviathan of a building, a third of a mile long, resembling the upper deck of a buried cruise ship peeking above ground.

It looks like art, but it’s actually engineering.” Dazzle painting originated in the UK, which in the early days of the Great War was losing ships to the new German U-boat wolf packs at a catastrophic pace—as many as 55 a week, according to Roy Behrens, a professor of art at the University of Northern Iowa, whose work focuses on camouflage.

With the success of the attacks, the U-boats widened their attack and began targeting civilian ships, like the liner Lusitania, which fell prey to a torpedo in 1915, killing 1,200 of the almost 2,000 people on board.

With all this in mind, Wilkinson designed paint jobs that were distorted checkerboards of black and white, with curves that, for example, mimicked waves and distorted the perception of length, height, and movement.

According to Claudia Covert, a special collections librarian at the Rhode Island School of Design, “The 3,000 ships painted with Dazzle were less likely to be hit, and when they were hit, it was in less vital parts of the ship.” The British had gotten quite good at Dazzle painting by the time the US entered the war in 1917.

“Where the British saw this as a kind of large art project and each ship had a unique design, the Americans created a catalog of plans, then sent the plans to Eastman Kodak for testing.” A physicist at Eastman Kodak built models and hand painted them, and then conducted a periscope test in tanks of water with a variety of marine backgrounds.

The approved, tested designs went to the government printing office, and identical sets of plans were sent to 13 ship districts that were charged with the task of painting the designs onto the vessels.

But they’d also begun escorting merchant and passenger ships in convoys of heavily armed gunships and, Behren says, surface vessels had become adept at finding and sinking submarines.

MacOS High Sierra bug: blank password let anyone take control of a Mac

Taking Mac control … the security flaw was initially discovered a couple of weeks ago and disclosed in an Apple developer support forum.

serious security flaw was found in the latest version of Apple’s macOS High Sierra that could allow anyone to access locked settings on a Mac using the user name “root” and no password, and subsequently unlock the computer.

patrick wardle (@patrickwardle) If certain sharing services enabled on target - this attack appears to work 💯 remote 🙈💀☠️ (the login attempt enables/creates the root account with blank pw) Oh Apple 🍎😷🤒🤕 pic.twitter.com/lbhzWZLk4v November 28, 2017 ‘This is really REALLY bad’ The security flaw was originally detailed as a solution to a user login problem on Apple’s developer support forum.

Some bug in authentication is ENABLING root with no password the first time it fails!” Security experts warned that the security hole was both embarrassing for the company and dangerous, allowing anyone with physical access – and in some instances remote access – to a Mac computer to gain full access to user data.

Edward Snowden commented on the bug saying: “Imagine a locked door, but if you just keep trying the handle, it says “oh well” and lets you in without a key.” Experts also warn against trying out the bug for yourself, as once enabled the flaw can then be more easily exploited even on a locked Mac.
