Adventurers in Server Containerisation
I have rebuilt the server – AGAIN
This time I’m using OpenVZ containers, a bit like virtual machines but with less overhead. The new setup is as follows:
Host system specs: 2×2.4GHz processor, 3GB RAM, 20GB OS disk, 120GB container disk, 2TB storage disk
The host runs a number of services to support the containers
- HAproxy – to handle host headers and forward the http requests to the containers
- NFS and Samba servers – to allow the LAN and the containers to access the storage disk
www container – hosts Apache, for hosting this website
MySQL container – hosts all the databases that the other containers need
Deluge container – hosts the Deluge daemon and the Deluge web front-end
Tomcat container – hosts Tomcat, for running my wife’s webapps

Nearly Christmas
Presents are bought, wrapped, and in some cases, posted… and Kevis is dressed for the season!
Hello World
Hi, my name is Kevis and I am a pet brick, and I have just moved in with my new owners. Before I came here I lived in a large pile of bricks, all neatly stacked and it was very boring. Now I live in a house, and watch my owners do things like eating and using their computers – which is much more interesting than seeing builders walking by.
My new owners have bought me a bed, a bowl and a collar – see pictures below. I am looking forward to my first walkies, but apparently I am not allowed out of the house yet :(.

Air Wick’s Colour Changing Candle
Recently we bought an Air Wick Colour Changing Candle, and was intrigued to find out how it worked.
It was quickly obvious that it cycled through RGB LEDs
We waited for it to burn down and found this:
After some experimentation, we found that pointing a TV remote at it also activates it:
From this, we were able to ascertain that it operates by detecting IR (infrared) – the black-coloured thing that looks like an LED is actually an IR receiver.
The fun never ends 😀
