Vi Keybindings in SBCL REPL

I'm (re-)reading "Practical Common Lisp" and going over the exercises/code with SBCL. I found the below script to help me with my Vi addiction :)

Error Handling in Python

I gave a talk at work about error handling in Python.
You can view it here.

What do you think? Did I miss something?

It's worth noting that after a while working with Go and the way it handles errors (if value, err = foo(); err != nil ...). If find my Go programs more verbose but more robust at the same time.

XFCE and Volume Keys

I'm currently playing around with XFCE. I have PulseAudio and wanted the volume keys to work (I'm a keyboard kinda guy. :). Here's a solution:

• Open Settings -> Keyboard -> Application Shortcuts
• Click on "Add"
• Type pactl set-sink-volume 0 +10% and then OK
• Hit the "up volume" button on your keyboard
• Click on "Add" (again)
• Type pactl set-sink-volume 0 -- -10% and then OK
• The -- is not a typo
• Clock on "Add"

Your volume keys sound work now.

Oh, and I find installing they "Greybird" theme [1] (from Ubuntu) makes things much nicer :)

[1] Install with yaourt -S xfce-theme-greybird and then select in Settings -> Appearance
