If you have already taken a course in algorithms, why read Grokking Algorithms (manning.com/bhargava)?

If you were learning graph algorithms, which approach would you prefer:

1. Imagine you have to take public transit from your home to your office. How do you figure out the fastest route? Use graph algorithms! OR

2. We can choose between two standard ways to represent a graph G = (V, E): as a collection of adjacency lists or as an adjacency matrix. Either way applies to both directed and undirected graphs.

I prefer the first way: lead with lots of examples, and clear writing. The second way is an excerpt from "Introduction to Algorithms"...that's how they start their section on graph algorithms.

Sample service script for debianoids

Look at LSB init scripts for more information.

Usage

Copy to /etc/init.d:

# replace "$YOUR_SERVICE_NAME" with your service's name (whenever it's not enough obvious)

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

• One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
• A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

• Unison for file synchronization
• EncFS for folder encryption

Studying for a Tech Interview Sucks, so Here's a Cheat Sheet to Help

This list is meant to be a both a quick guide and reference for further research into these topics. It's basically a summary of that comp sci course you never took or forgot about, so there's no way it can cover everything in depth. It also will be available as a gist on Github for everyone to edit and add to.

Data Structure Basics

Array

Definition:

• Stores data elements based on an sequential, most commonly 0 based, index.
• Based on tuples from set theory.

An OpenCV script that you can use to transform multiple images into one
single image containing the minimum pixel value for each pixel of the
input images. The input images have to be of the same dimensions!
