Saturday, 24. December 2011 Week 51


This morning I started to prepare the bagagges for my trip to 28C3 and for the two months in Sydney.
While stowing away all my stuff in boxes so I can sublet my room I found old boxes with stuff, which I did stow away over a year ago when I went to Sydney the last time and I've never even thought about since!

As I did not have time to open them today I don't even know what is in those boxes. Probably I should just throw them away when I come back from Sydney, there can't be anything important in there :-)

Soiree BAM

One of the rare concert evenings at Satellite where even the technicians had to have an additional badge (but nevertheless this is another one of a kind memory): Soiree BAM 2005

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.


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/ and create the following crontab entry to check the disk usage every day at half past midnight.

30  0  *   *   *     /root/

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.

(Mini) Bacon and Egg Cups

Last week I stumbled upon this delicious looking bacon and egg cups recipe and thought that I should try it sometimes, which I did this morning.
Since I don't have a real muffin tin I used a somewhat smaller cake tin, with the result that the handling was a bit more delicate and also my cups are more like 'mini' cups (which is not necessarily a bad thing because the bacon I bought was also smaller than expected and thus it matched perfectly).

Bread with holes
This is the result of the first step in the recipe and all what is leftover once I was finished. Not very useful for putting jam on it anymore, but perfect to stir the next cheese fondue :-)


  • 1 slice of bread per muffin cup (1 slice per 4 cups for the 'mini' version)
  • 2 slices of bacon per muffing cup (use small slices for the 'mini' version)
  • 1 egg per muffin cup (same for the 'mini' version)
  • 1 tablespoon shredded cheddar cheese per muffin cup (optional, I used some parmesan instead)
  • salt and pepper to taste


  1. Preheat oven to 375 degrees.
    (that's 190 degrees celsius)
  2. Use a cookie cutter to cut circles out of each piece of bread.
  3. Grease a muffin tin and press circles of bread in the muffin cups. Place in the oven and bake for 5 minutes or until bread is slightly toasted. Remove from oven.
    (be careful when doing the 'mini' version, your bread will be toasted in well under 5 minutes)
  4. Cook bacon in a skillet until halfway cooked (approximately 3-4 minutes).
    (here again: when using small bacon slices they will be ready in less than a minute, be careful to not make them too crispy otherwise they will be hard to fit into the cups)
  5. Place 2 slices of bacon on top of the pieces of bread to form a cup (the bacon should cover the bread and the sides of each cup).
  6. Crack an egg into each muffin cup (on top of the bacon). It helps to discard a little bit of the egg white after cracking and before pouring into the muffin cup.
    (for the 'mini' version keep the surplus egg white in a bowl and use it to make some 'only-white' cups, one egg gives enough surplus egg white for another cup)
  7. Place in the oven and bake for 18-20 minutes or until the eggs are set.
    (for the 'mini' version use 8-10 minutes, I almost burned mine!)
  8. Sprinkle cheddar cheese over each egg and continue to bake until cheese is melted (this step is optional).
  9. Season with salt and pepper to taste and serve.

The advantage of my 'mini' version is that you will end up having plenty of little bacon and egg cups, yummy :-)

When attending conferences you often receive a badge granting you access (which usually is not much more than a nametag with some logo). Also when working at concerts and festivals you receive a badge identifiying you as staff. I regularly keep these as souvenirs which remind me of the amazing times passed at those events.

Over the time there are now a couple of badges hanging on my closet and I think it would be nice to be able to look through them on my laptop. Thus this new Badges category in the weblog.

My idea for now is to put a new badge online every day until Christmas like some form of an Advent calendar.

Here is the first one, it is from the IPv6 Business Konferenz:
