• USBdriveby - exploiting USB in style

  USBdriveby is a device you stylishly wear around your neck which can quickly and covertly install a backdoor and override DNS settings on an unlocked machine via USB in a matter of seconds. It does this by emulating a keyboard and mouse, blindly typing controlled commands, flailing the mouse pointer around and weaponizing mouse clicks. In this project, we'll learn how to exploit a system's blind trust in USB devices, and learn how a $20 Teensy microcontroller can evade various security settings on a real system, open a permanent backdoor, disable a firewall, control the flow of network traffic, and all within a few seconds and permanently, even after the device has been removed.

• The Netflix Tech Blog: Introducing Atlas: Netflix's Primary Telemetry Platform

  The primary goal for Atlas is to support queries over dimensional time series data so we can slice and dice to drill down into problems. This means we frequently have a need to perform a large aggregations that involve many data points even though the final result set might be small.

• Hacker's guide to Neural Networks

  My personal experience with Neural Networks is that everything became much clearer when I started ignoring full-page, dense derivations of backpropagation equations and just started writing code. Thus, this tutorial will contain very little math (I don't believe it is necessary and it can sometimes even obfuscate simple concepts). Since my background is in Computer Science and Physics, I will instead develop the topic from what I refer to as hackers's perspective. My exposition will center around code and physical intuitions instead of mathematical derivations. Basically, I will strive to present the algorithms in a way that I wish I had come across when I was starting out.

• MetricsGraphics.js - a library based on D3.js, optimized for visualizing and laying out time-series data

  MetricsGraphics.js is a library built on top of D3 that is optimized for visualizing and laying out time-series data. It provides a simple way to produce common types of graphics in a principled, consistent and responsive way. The library currently supports line charts, scatterplots and histograms as well as features like rug plots and basic linear regression.
