Heartfelt Thanks

Thank you Apple and Steve Jobs for keeping Adobe Flash off my iOS devices and making it easy for me to remove it from my Mac OS X gear. The stability, security, performance, and battery life I am enjoying now were not possible on a Flash-enabled machine.

Mac OS X DNS mysteries explained a bit

Hannes Schmidt has an excellent little write up of why Mac OS X DNS seems a little unpredictable at times when using DHCP or VPN assigned name services; this helps one understand why the results are a surprise or why dig in a terminal window delivers different results from your browser on the same host.
