Best Python debugger

I don't use pdb often, but today, I needed one. I suspected that there should be a pdb module for emacs. Although GUD requires separate wrapper to PUD, there is a built-in module in Emacs. I just realized that GUD is a wrapper for another process instance. Not a big deal.
Create this file in somewhere PATHable and name it pdb.

#!/bin/sh
exec python2.6 /usr/lib/python2.6/pdb.py $1 $2 $3 $4 $5 $6 $7 $8 $9

And then, you are good to go. Someone mentioned that backtracing does not work across modules. I didn't test that because his/her post was dated long time ago with emacs 21.
With pdb, 'C-x +' (balance-windows) will be very useful.

Emacs pinky problem

I am not talking about L-CTRL sitting on a lower left corner. I already switched CAPS and L-CTRL. However, as Emacs still requires so many CTRL key strokes, my left pinky is getting tired. Now I am using R-CTRL and R-ALT. This works in my work desktop, but several problems await me.

1. Some machines don't understand R-ALT and R-CTRL.
2. Laptop and Desktop keyboard layout make me confused for these keys.

Intentionally, xmodmaps are turned off these days to remind myself to use Right side.

Nehalem architecture

Intel took a new approach to resolve the bandwidth problem, traditionally Intel suffered. If Intel Core 2 duo was focused on more efficient computation, this is major replacement of architecture design. As a programmer, we can just enjoy more clock cycles on less power consumption :)

Here is an article about a very nice overview.
