Cliff Stoll (previously) is a computing legend: his 1989 book The Cuckoo's Egg tells the story of how he was drafted to help run Lawrence Berkeley Lab's computers (he was a physicist who knew a lot about Unix systems), and then discovered a $0.75 billing discrepancy that set him on the trail of East German hackers working for the Soviet Union, using his servers as a staging point to infiltrate US military networks.
Twitter's openness is its strength, and also its weakness: the ease with which new accounts can be created makes it into an amazing tool for free expression, and also a perfect venue for vicious harassment (see also); but Instagram (a division of Facebook, the home of the walled garden) has announced a suite of anti-harassment tools that seem like they'd be compatible with Twitter, raising the obvious question: why hasn't Twitter already deployed them?

The Evil Mad Scientists were presented with a challenge: inscribe one of Cliff Stoll's hand-blown Klein bottles, an object of surpassing beauty and odd topology. They modified an Eggbot plotter to etch the surface of a Klein bottle with a diamond engraver attachment.
This may be the largest Klein bottle (lovely multilingual dissonance there!) ever made. Klein bottles are basically Moebius strips with one extra dimension — bottles that have one continous volume without any "inside" or "outside." This Klein bottle was made by Cliff Stoll (who wrote the classic true-cybercrime thriller The Cuckoo's Egg) who runs the Acme Klein studio in the East Bay. — Read the rest
What do you get when you extrude a Mobius strip into the third dimension? A fractional-dimensional object with zero volume: a Klein Bottle! And who manufactures and sells the world's finest Klein Bottles? Hippie-cum-Physicist-cum-Sysadmin-cum-International Crime Fighting CyberSleuth-cum-Author, Cliff Stoll. What a wonderful freak! — Read the rest
