A little experiment in human behaviour

We keep a jug of filtered drinking water in our fridge. The water from the tap is perfectly palatable but chilled water is that bit nicer so the jug is popular.

It is a matter of seconds to fill the jug but it takes several minutes to trickle through the filter and a lot longer to cool down to a nice level of chilliness. It is therefore very frustrating to reach for the jug and find it empty and I take care to top it up every time I use it. Unfortunately other members of my family do not seem to be as considerate and on many occasions I have gone to the fridge only to be disappointed by a nearly empty jug.

My usual response in circumstances like this is to express my dissatisfaction loudly in what my kids term a "Father Rant". This makes me feel better for a little while but long experience has convinced me that such rants are incapable of producing any lasting change of behaviour. On this occasion therefore I decided to be a little more scientific.

Analysing the problem it soon became clear to me that I was probably the only person who ever filled the jug. Others who used the jug after me found it contained enough water for their needs and used it without replenishment. Because they did not need to fill the jug to meet their own needs they did not think to fill the jug afterwards. When I next came to look for the jug it was invariably almost empty.

My first thought was to stop filling the jug after I use it. My thinking was that I I stopped filling then there wouldn't be enough water for others and eventually it might dawn on them that they have to start filing it themselves. In the interest of science however I decided to take an even bolder approach in order to test the hypothesis in the extreme case. I started emptying the jug completely every time I used it. This required a certain amount of subterfuge but I managed to pull it off for a couple of days.

The results were immediate and conclusive. Every time I went to the fridge I found a full jug of water despite my emptying it completely every time I used it. Clearly the empty jug was providing the signal to others to start filling as anticipated.

I was initially enthused by my experiment. Finally I had discovered a method to change other people's behaviour through the application of scientific principles. How many more familial annoyances might I be able to deal with in a scientific manner: The lights that are left on unnecessarily? The dishes that are not cleared off the table? The toys that seem to accumulate in inappropriate locations?

I was smugly contemplating such future scientific triumphs after having just replaced a carefully emptied jug into the fridge when I noticed my my youngest daughter go to the fridge open it and reach for the jug.

The look of disappointment on her face when she saw it was empty broke my heart and dragged me down to earth with a crash.

The scientific experiments are over. If it is my lot in life to be the filler of water jugs so be it.

Science has yet to provide the cure for a broken heart. ;)

There is little on this earth more able to change a father's mind than a look of disappointment on his child's face. And yes, I speak from experience ;)

My First Gaming Mouse: Logitech G300

I bought a gaming mouse yesterday a Logitech G300, here my initial thoughts. What is a gaming mouse?  There are a wide variety of devices available classified as gaming mice but a few features  seem common: 1. Wired rather than wireless: Although some high end models are wireless wired connections are just better and faster than wireless so most gaming mice stick with wired. As a bonus wired mice don't need batteries so the mouse is lighter.  2. High response rate: 1 to 2ms response rate so the mouse immediately responds to input.  2. High DPI. Gaming mice invariable boast high DPI numbers from 2,000 DPI upwards. This makes the device very responsive to the smallest movements.   3. Adjustable DPI . High DPI improves responsiveness but reduces precision so gaming mice generally allow you to adjust the DPI down for precise work such as pulling off headshots in sniper mode. Generally the mouse allows dpi to be changed on the fly by pressing a button.  4. Extr

Portal 2 two screen coop on one PC.

I mentioned before that I intended to try Portal 2 in "unofficial split screen co-op mode. Well split screen on a small computer monitor is a recipe for a headache especially when the game defies gravity as much as portal. However a minor bit of extra fiddling allowed us to drive two seperate screens from one PC. The Steam forums describes a complicated method of doing this that I couldn't get working so this simpler method which worked for me might be of use to someone. 1. First I followed the instructions in this post to get split screen multi-player working: http://forums.steampowered.com/forums/showthread.php?t=1847904 A minor issue not mentioned is that you need to enable the console from the keyboard/mouse options menu I am using keyboard and one wired Xbox360 controller as suggested. Getting the controller to switch to channel 2 was tricky at first but as Chameleon8 mentions plugging it out and in again during loading works. The trick for me was to do the plug / p

Android Tip 3: Sharing a Folder between multiple users of an Android device

Android has allowed multiple user logins for quite a while now. This is can be very useful for tablets which are shared by family members. Normally Android erects strict Chinese walls between users preventing them from using each others apps and viewing each others files. This is a useful security feature and ensures your kids don't mess up your work spreadsheets when screwing around on the tablet and should also prevent them from buying €1,000 worth of Clash of Candy coins on your account. Sometimes however you really do want to share stuff with other users and this can prove surprisingly difficult. For example on a recent holiday I realised that I wanted to share a folder full of travel documents with my wife. Here are some ways to achieve this. 1. If you have guaranteed internet access  then you can create a shared folder on either Dropbox or Google drive. Either of these has the great advantage of being able to access the files on any device and the great disadvantage of bein
