Yet another great event which no longer exists: ClosedAir 2006

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