What I’ve Learned About Neural Network Quantization (Pete Warden) — lots of nerdy gems—for example, on the importance of being able to exactly represent zero: The problem is that the real value of zero shows up a lot more often than you’d expect in neural network calculations. Convolutions are padded with zeros at the edges when filters overlap, and the Relu activation function gates any negative numbers at zero. This means that any error in the zero representation contributes disproportionately to overall results.
Complete Control of the UI Feedback Loop — paper on a design problem in Android, whereby with just two permissions you can then do all sorts of nasties: quietly mount practical, context-aware clickjacking attacks; perform (unconstrained) keystroke recording; steal user’s credentials, security PINs, and two factor authentication tokens; and silently install a God-mode app with all permissions enabled.
