Fooling Neural Networks in the Physical World with 3D Adversarial Objects · labsix
This is amazingly weird stuff. Fooling NNs with adversarial objects:
Here is a 3D-printed turtle that is classified at every viewpoint as a “rifle” by Google’s InceptionV3 image classifier, whereas the unperturbed turtle is consistently classified as “turtle”.

We do this using a new algorithm for reliably producing adversarial examples that cause targeted misclassification under transformations like blur, rotation, zoom, or translation, and we use it to generate both 2D printouts and 3D models that fool a standard neural network at any angle. Our process works for arbitrary 3D models - not just turtles! We also made a baseball that classifies as an espresso at every angle! The examples still fool the neural network when we put them in front of semantically relevant backgrounds; for example, you’d never see a rifle underwater, or an espresso in a baseball mitt.

Designing the Perfect Anti-Object
This pale, amorphous lump of sculpted concrete is designed to resist almost everything in a city that it might come into contact with. Named for the London authority that commissioned it, the Camden Bench has a special coating which makes it impervious to graffiti and vandalism. The squat, featureless surface gives drug dealers nowhere to hide their secret caches. The angled sides repel skateboarders and flyposters, litter and rain. The cambered top throws off rough sleepers. In fact, it is specially crafted to make sure that it is not used as anything except a bench. This makes it a strange artifact, defined far more by what it is not than what it is. The Camden Bench is a concerted effort to create a non-object.

Skeuomorph
word of the day, via a comment on http://www.jwz.org/blog/2012/01/snow-crash-simulated/ : 'A skeuomorph /ˈskjuːəmɔrf/ skew-ə-morf, or skeuomorphism (Greek: skeuos—vessel or tool, morphe—shape),[1] is a derivative object that retains ornamental design cues to a structure that was necessary in the original.[2] Skeuomorphs may be deliberately employed to make the new look comfortably old and familiar,[3] such as copper cladding on zinc pennies or computer printed postage with circular town name and cancellation lines'

What is data oriented design?
'organizing your data for efficient processing, especially with respect to cache misses etc.' -- essentially an approach to breaking good OOP design practices in order to gain performance, seems to have come from the game-dev community
