Raspberry PI - Lots of Links To Information

** Updated Sep 8, 2012 **

One of my work habits when goggling around learning something is to keep a Gmail draft with links and sometimes notes to prevent the problem of finding something and then NOT being able to find it later.

I have decided to put these here instead of in a Gmail draft, as I can edit in place to add more later. Some of these may generate new blog entries later.

Loff
http://e2e.ti.com/support/logic/f/151/t/118676.aspx
      Ioff - The maximum leakage current into an input or output terminal of the device, with the specified voltage applied to the terminal and VCC = 0 V.The Ioff protection circuitry ensures that no excessive current is drawn from or to an input, output, or combined I/O that is biased to a specified voltage while the device is powered down.

Python 2 3

=========

Both python 2 and 3 from command line

$ python3 -V => Python 3.2.3

$ python -V => Python 2.7.3rc2

http://www.raspberrypi.org/phpBB3/viewtopic.php?f=32&t=14501   idle vs. idle3

     If you are learning Python, use Python 3 (IDLE3), not 2.X (but a lot of old code is still 2.X)

     There are some differences in 3 (language "cleanup") that make 3 not totally backwards compatible with 3
