Keep Linux Console From Dimming The Screen

There are many ways to do it depending on your context, i.e. whether you’re working with headless setup that doesn’t need to run X server – plain old console – or with an X-based setup.

In my particular case I had  a CentOS box that ran without X server and experienced some obscure, intermittent lockups. So, I needed to hook up the display, hoping to see some output like kernel call trace or maybe some error messages the box locks up the next time. The problem was that the system would dim the screen and when the box locked up I couldn’t see anything that might had been printed on stdout.

After quite a prolonged session of error and trial, what I learned was that simply issuing setterm -blank 0 in a terminal over ssh session (didn’t try to directly enter this command, let me know if this works for you) wasn’t working.  So, what I ended up doing was adding

% echo “/usr/bin/setterm -blank 0” >> /etc/rc.local

to the end of /etc/rc.local and rebooting the box.

That did it for me (finally! lol)

Extracting a Radio Station URL from Banshee 2 SQLite DB

I’ve wanted for a while to extract a radio station url for HBR1, Ambient from Banshee 2.0.1.

My first thought was to grep recursively and disregarding character case for ‘hbr’ in $HOME. That didn’t work.

After some time I realized that probably Banshee stored most of the data in a sqlite db. I was right about that, but  finding the radio station url still wasn’t as simple.

Here’s what I did to get it printed out on my console:

~/.config/banshee-1 % sqlite3 banshee.db ‘select * from CoreTracks’ | grep -i hbr

Yeah, not pretty, but who cares as long as you can extract your data, right? Of course, if you’re going to re-use the output in your scripts you’ll have to figure out how to make the output prettier. If you do that, drop me a line in the comments section, please.
