Let's start the last week of this badge advent calendar with another tech conference badge (looks like the conference no longer exists, thus no link to any website): San Francisco LinuxWorld 2007

And there the other student music festival which managed to provide badges: Artiphys 2008

Quick and dirty way to get an alert before your server starts to go crazy because of a full disk.

This script checks if a disk is more than 75% full.

#!/bin/bash

df -h | awk '/%/ {
        limit = 75
        percent = sprintf("%d",$5)
        if ( percent > limit ) {
                print "Warning: ",$6," (",$1,") is to ",percent,"% full:"
                print $0
        }
}'

Save it under /root/check_disk_usage.sh and create the following crontab entry to check the disk usage every day at half past midnight.

30  0  *   *   *     /root/check_disk_usage.sh

Assuming your host has configured an MTA and defined a recipient for root@<yourhost>, you should get an e-mail whenever a disk is more than 75% full.

Now on to the badges of 2008, as every year: Festival Balelec 2008

(via vowe.net)

The only time (for now) when I got to fly in a helicopter for a music festival was at: Caprices 2009

And once more there is a badge from: Festival Balelec 2009

Here comes the largest badge in my collection: Festival de la terre 2009

Probably the most 'famous' badge in my collection: Montreux Jazz Festival 2009

With the 2009 badges, I can almost fill another week. Let's start with: Metropop Festival 2009
