Use Meld as a diff tool for git

To view git diff through meld, my favorite diff viewing tool, do the following:

1. Write a small script in ~/bin/gitdiff, or wherever you like to store your scripts
   #!/bin/bash
meld $2 $5
   
   
2. git config --global diff.external ~/bin/gitdiff

Done!

RESTful API development using Node

Below are some helpful things I've come across while developing a RESTful API for a project of mine. I'll be updating this as I go.

• REST-esting using curl -- a guide to using curl for testing RESTful API's
• Postman Chrome Extension. Much better than using curl, in my opinion. 
• Apigee is a web service meant to serve as a middleman between your server and clients. Useful for things like rate limiting, limited JSON->XML conversion, and even load balancing. 

Fixing Penn State Wireless Network Stability Issues on Linux

On Linux Mint (and I'm assuming most Gnome-based distributions of Linux), NetworkManager does a bad job staying connected to the new psu network that has spread to most of campus.
wicd is an alternative network manager that seems to relieve a lot of the problems that NetworkManager had.

Install wicd
$ sudo apt-get install wicd
Then edit or create an encryption template "psu" as /etc/wicd/encryption/templates/psu. Note that this file may exist already but is probably outdated (as of today, mine was outdated). Find my version of the psu encryption template here: https://bitbucket.org/zachwolfe/dotfiles/src/2dc9a24fbc7b/etc/wicd/encryption/templates/psu
Then open the wicd-gtk client and connect to the "psu" network using the "psu" encryption template you just defined. You should also select the "use these settings for all networks sharing this essid" checkbox as well for obvious reasons.
