This site was written on a mid-2010 2.8GHz Core i7 15” anti-glare MacBook Pro on OS X Mavericks. It’s still zipping along on a 512GB m4 SSD and 8GB of RAM.
It’s generated by Jekyll and hosted on Digital Ocean. It meets WCAG AA guidelines for accessibility and (for the most part) W3C standards for HTML5 and CSS3. When it’s time for work, I use Sublime, GitHub, Transmit, CodeKit, and a variety of useful open source utilities.
I also rely on great software like Photoshop CS6, Lightroom 4, Photomatix, 1Password, Tweetbot, Clear, Evernote, Dropbox, Parallels, and XCode.
And as far as photography gear goes, I use my Nikon D5000 with the 18-55mm f/3.5-5.6 kit lens, Nikkor 35mm f/1.8 prime lens, Sigma 10-20mm f/4 wide angle lens, and a Nikon SB-600 flash.
