  • Programmer Makes Self-driving Toy Car Powered By Raspberry Pi, Arduino, Python

    On his blog, Zheng explains that the complete system consists of three parts: the input unit, processing unit and the RC car control unit.

    The input unit consists of a Raspberry Pi Model B+ attached with a camera and an HC-SR04 ultrasonic sensor. This unit collects the data (color video and sensor data) that is sent to a computer over local WiFi with the help two client programs running on Pi.

    The processing unit receives the video data from Raspberry Pi and it’s converted to gray scale and decoded into numpy arrays. Zheng further explains the other jobs performed in the processing unit — “OpenCV Python neural network training and prediction (steering), object detection (stop sign and traffic light), distance measurement (monocular vision), and sending instructions to Arduino through USB connection.”

  • Heaptrack v1.1.0 release
    Better memory profiling on Linux After more than a year of work, I’m pleased to release another version of heaptrack, the Linux memory profiler! The new version 1.1.0 comes with some new features, significant performance improvements and – most importantly – much improved stability and correctness. If you have tried version v1.0 in the past and encountered problems, update to the new v1.1 and try again!
  • Ten Years of Vim
     

    The philosophy behind Vim takes a while to sink in: While other editors focus on writing as the central part of working with text, Vim thinks it's editing.
