Toolbox

These are the tools I use to get my jobs complete.

Depending on the requirements these are used in concert with each other. And none of these are sacrosanct, if I find better or am recommended something better, a tool may be relegated to the dust bin as many have in the past.

Frameworks

Kohana
PHP framework with very clean and easy to read code.
Django
Python Framework with a great built in admin to jump start content input
JQuery
JavaScript Framework. It's ubiquitous and makes JS code so much easier to prototype new features.
JQueryUI
Lots of great UI components to quickly make admins more user friendly

OS

OS X - Mountain Lion
This is my main Development Machine, it has most of the awesome apps I use to get my work done and everything looks just a tad nicer.
Ubuntu Server & Desktop
Most of the servers I setup are Ubuntu servers including the one hosting this site and my home media centre is run on Ubuntu Desktop.
Windows Server & Desktop
I keep a Windows machine close. Any C# development is too heavy to run in a VM for any length of time. Currently on Windows 8. Also have Windows 7 and Windows XP on VMs just in case I need to test them out.

Search Indexing

Solr Search

Desktop Apps

Skitch
Skype
Adobe Masters Suite
Transmit
TextMate
Sublime Text Editor
This is becoming my TextMate 1 replacement for 90%. It has a VI mode, all the shortcuts I am used to from TextMate and most of the plugins and more.
Safari
Firefox
Chrome Browser
VMWare Fusion

Command Line Tools

Brew
After a while using MacPorts it was a breath of fresh air to use Homebrew, the compiling was way shorter as it didn't compile things that already existed in OSX. And it was colorful:)
Git

Web Apps

Gmail
Harvest
Github

Tools I am keen to learn

These are ones that I am giving serious thoughts to either replace or include it the box.

Symfony2
It's getting attention from the Drupal community because components are being included for Drupal 8.
CodeIgniter
Similar and fork to Kohana with a large following.
CoffeeScript
My friend Colin Olson has been pitching this so I am keeping an eye on it.
Flask
The route I would like to take in to the python world.
Wordpress - Advanced Custom Fields
Most of the programmers I know who use Wordpress swear by this tool.

Dust Bin

These tools have seen their day, I don't really use them any more in favour of better or possibly just more popular tools.

YUI2
This seemed to have promise but didn't get the pickup it deserved. I love their autocomplete flexibility and usability.
