I’m looking for a fast and reliable way to read/parse large PDF files in Ruby (on Linux and OSX). Until now I’ve found the rather old and simple PDF-toolkit (a pdftotext-wrapper) and PDF-reader, which was unable to read most of my files. Though the two libraries provide exactly the functionality I was looking for. My […]

VisuAlgo was conceptualised in 2011 by Dr Steven Halim as a tool to help his students better understand data structures and algorithms, by allowing them to learn the basics on their own and at their own pace. Together with his students from the National University of Singapore, a series of visualisations were developed and consolidated, from simple sorting algorithms to complex graph data structures. Though specifically designed for the use of NUS students taking various data structure and algorithm classes (CS1010, CS1020, CS2010, CS2020, and CS3233), as advocators of online learning, we hope that curious minds around the world will find these visualisations useful as well.

Python comes with several built-in modules, but the Python community has more to offer. It’s the modules that makes python so powerful! Third party modules add so much more functionality to Python. So it's time to learn how to install these modules so that we can use those in
