Kindle is not for technical books
Here are some ways that Kindle (App for Mac OS X) fails me:
- Does not support code blocks (i.e.: pre formatted text)

Arduino PWM & Power Saving

My take on this is that Intel was focussed on raw speed as a performance metric, since they have ( Read more... ) -
Das Blinkenlichten

The 220 was a 10 digit plus sign BCD machine. Each register was displayed on the console as an 11 x 4 matrix of neon bulbs. The bulbs were in a plastic "eggrate" matrix. The kicker, and the reason for the ( Read more... ) -
AppleScript - replacing passwords
Here's an AppleScript that I'm using to replace a bunch of passwords every month. The corporate network expires passwords after a month, so I have to go through all my keychain items to replace the stored password (as opposed to remembering the password and using it dozens of times a day).
( code behind the cut, of course. )
