Like most people I have used Microsoft Windows for years and am very familiar with it, however Windows is by no means an ideal operating system – it is sluggish, greedy in using system capacity and insecure. From power-up, my XP pc takes a good ten minutes before you can do anything useful (during which time the hard drive sounds like a mosquito on caffeine), this does not include the time taken to run anti-virus and anti-spyware scans which slow performance dreadfully if run in the background. I know things would improve if I formatted the C drive and reinstalled XP, but having done this before I know it is an all day job and will not prove to be a panacea. I am not even going to attempt to load Vista, although my pc exceeds the minimum specification the experiences of others lead me to suspect it would run about as swiftly as a snail in wet tar. My laptop, also XP, is a little older but is kept deliberately free of all but essential software and performs somewhat better as a result.
So, a few months ago. I decided to take the first steps along the path to becoming OS neutral and loaded Ubuntu onto the laptop. Initially, I found things a bit difficult. The version at the time (Feisty Fawn I think) worked OK for surfing the web and word processing, but seemed a bit tricky to get to grips with and to be honest, I didn't use it much. However all that changed when the current (Gutsy Gibbon) Ubuntu release came out. This is much more intuitive and (crucially) it makes it easy to open documents stored on both of the laptop's Windows partitions, something I never managed under the previous release. My children have no problems using Ubuntu at all and it has recognised every usb device I have tried with it so far.
Not everything in Gutsy was easy though, at first I just could not figure out how to load new software. Being a Windows user I was used to downloading from the internet and running the installer but his didn't seem to work with Ubuntu. Eventually it dawned on me that the Synaptic Package Manager and the add/remove utility actually makes the job a lot easier than the Windows method (OK, I know I should have looked at the help files, but it never occurred to me that anything other than the Windows style method would work. “Assume nothing, young Grasshopper” as a wise man may once have said). You have a list of hundreds of applications, you tick the ones you want to add or remove and let Ubuntu get on with it. Simple as that. I have now loaded one program not listed in the package manager and that was tricky, but a bit of Googleing and trial and error got me through eventually. This is an area which could do with attention in future releases, if you have to open the Terminal to enter commands then most general users (myself included) are going to be put off. Otherwise installing is a breeze.
Playing mp3s and dvds is a better under Gutsy than Feisty, but I would suggest adding the VLC player (using the package manager) which copes with just about anything you throw at it (I use it on Windows too). Open Office is great, on the Windows side I use it and Microsoft Office 2003 pretty much interchangeably and I certainly will not be getting Microsoft Office 2007, anybody tempted to download a dodgy copy of the Microsoft product really now has no excuse, download a legitimate copy of Open Office instead, it's free (and guilt free too).
Overall, I currently use XP and Ubuntu about the same amount. You can't get Photoshop or i-Tunes on Ubuntu and video editing is under-supported at present, but for most Windows software there is a (usually free) linux alternative. And with new versions of Ubuntu released every few months (Hardy Heron – where do they come up with these names? * - is out next month) Ubuntu is rapidly becoming a polished OS. It is compact, very stable, runs fine of old underpowered systems, and (at least from Gutsy Gibbon) much easier to get to grips with than I expected. So, two operating systems down, only Mac OSX to go...

* suggested names for future distributions
Bloated Bill – buggy version to make Microsoft users feel at home
Slick Steve – polished but slightly pricey version aimed at Mac users
Obscure Ocelot – Terminal-only version for those die-hards who believe anyone who needs a graphical user interface is unworthy to use Linux
Colourful Chameleon – Ubuntu without the brown theme

On...Cold Showers
It seemed like a good idea at the time. It was January and after the excesses of Christmas thoughts naturally turn to taking exercise, eating more healthily and generally finding something to feel smug about.
I considered going to bed early in order to get up at the crack of dawn to do a bit of work before breakfast. I then realised that dawn was actually some time after I normally drag myself out of bed anyway and I would therefore actually be having a lie-in. And then it happened, I was innocently watching Countryfile when Michaela Strachen comes on doing an investigation of the 'benefits' of cold water swimming. Stimulates the immune system apparently. Well the Council swimming pool does do a pretty good impression of the average winter water temperature of the sea or a lake but was it possible to investigate the physiological effects closer to home?
Cold water cures were fashionable in Victorian times. Charles Darwin, looking for a cure to the chronic illness from which he suffered following his voyage on the Beagle, undertook a regime of cold showers and being wrapped, mummy-like, in wet sheets. His children would apparently stand outside his shower room in the garden 'listening to his groans' (1). So, following Darwin's example (not that I have any mysterious tropical diseases as far as I am aware) I decided to try cold showers. I could test my physiological reactions to cold water with minimal time an effort but still start off with a nice warm shower, only switching on the cold on after I had washed in comfort.
And so the experiments began. It takes my shower about five seconds to go from hot to cold during which time the brain registers (a) 'all OK', (b) 'nothing wrong with an little bit of cold water, never did anyone any harm, what's all the fuss about anyway', to (c) '****!, that's freezing' On day one I managed a not particularly impressive brisk count to five, accompanied by various involuntary noises, before I switched off. In the aftermath a slightly elated feeling was noted. In subsequent days I managed to count to five more slowly, eventually managing rather longer periods. The need to vocalize and the post-dousing elation remained.
The vocalizations are probably linked to the hyperventilation reaction of the human body when immersed in very cold water. It is this involuntary rapid breathing (Countryfile explained) which can easily lead to drowning (and a good reason to experiment in the shower if you ask me). Although not hyperventilating, I was certainly breathing more oxygen in as the cold water hit me, the urge to vocalize is possibly part of a coping mechanism akin to swearing when you stub you toe, it distracts you a little from the pain. The post shower high may be linked to to release of 'feelgood' chemicals by the brain in response to the physical stress on the body.
Although never actually pleasant, the experience became more tolerable after a few days. Interestingly, standing absolutely still with the water hitting the back of your neck and running down the middle of your back feels much less cold than if the water lands on your shoulders or front, although the subsequent euphoria is reduced a little as a consequence.
Important: if you try cold showers yourself it is vitally important that you remember to reset the shower to hot afterwards. Failure to do so may result in protests from other members of your family!
