Writer and programmer Peter Welch has penned an amusing and terrifying essay called “Programming Sucks,” which sheds some light on why so much software is unstable and insecure. A choice quote: “Not a single living person knows how everything in your five-year-old MacBook actually works. Why do we tell you to turn it off and on again? Because we don’t have the slightest clue what’s wrong with it, and it’s really easy to induce coma in computers and have their built-in team of automatic doctors try to figure it out for us.” follow link
Single Time Machine Backups
Tired of Time Machine running all the time? You can turn it off in the Time Machine preference pane, but still initiate a single backup by choosing Back Up Now from Time Machine's menu bar icon. Of course, your backup is much less likely to be up to date, but Time Machine won't be taking any resources while you're trying to work.

I remember dreaming about code, and waking up with the solution. And that was just in Applesoft Basic and Assembly Language. Now I just try hard not to think about web page design at night. Doesn't always work.
