…all the good ones were taken


Thanks for dropping by.

This is my new site (now at squidman.net) and replaces my old site which was hosted on Apple's MobileMe service (at web.me.com/adg, which is being discontinued).

If you were previously subscribed to my blog RSS feed, please note it's moved (to here).

I write software for OS X and iOS, some of which is available here, and most recently, books for O’Reilly. I (very occasionally) blog tech content - hopefully you find something of interest here.


Here's some of the stuff I've written to scratch my own itch. Enjoy!


Use squid as a personal proxy server.


A simple way to burn disk images.


A simple way to erase optical media.
