Changing Times for Wireless

Incontinence is certainly no laughing matter and we’re ever mindful of the fact that for most of us good health is only a temporary condition, nevertheless we couldn’t resist the briefest of wry smiles after hearing about the SIM System electronic underpants. The basic concept is that when sensors embedded in the wearer’s pads detect moisture it sends an alert via a wireless link to a monitoring station, at a nursing home for instance, so staff can provide prompt assistance to a patient, when they need it. Over a period of several days the timing and frequency of the alerts is analysed, which could help carers and medical professionals determine if there’s pattern and subsequently assist with treatment or care strategies. Hopefully we’ll never have need of such a device – though the odds don’t look good as we live longer – so it’s good to know technology can help if, or rather when our plumbing lets us down.

The Mesmerising Blob of Infinity

Quite frankly, these days’ screensavers are a waste of time. LCD monitors do not suffer from the ‘screen burn’ effect that affected old style CRT monitors when left to display the same image for hours on end. That said, a blank or simple floating logo screensaver on a black background can provide a small power saving when a PC is left idle (though there are much better ways to achieve it). On the other hand password protecting a screensaver is a handy way of keeping prying eyes off your PC when it is left unattended for any length of time. Well, that’s my excuse for mentioning Zoom Mania. It’s a wacky, trance-inducing fractal blob thingy that floats around the screen giving off streams of smaller blobs that appear to disappear into infinity. You can move it around, zoom in and out and do all kinds of weird and wonderful things to the image. Try it after a couple of pints and I guarantee you won’t get any work done. It’s freeware but when you install it watch out for very kind offers to load browser toolbars and change your home page, unless of course you want it to…

Explore Your Computer

Windows has a number of diagnostic and system monitoring tools built in but this one, called System Explorer puts everything you need to know about your computer, and what’s it doing now, and in the past, into one very convenient and easy to use package. Here’s just a taster of what it can do. You can view information about running processes, startups, Explorer, IE Add-ons, uninstallers, drivers, services, connections and open files. You can check which programs and files were opened, and when, take snapshots of your Registry and later compare them if something has gone wrong to see what’s changed. It uses fewer resources than the Windows utilities and there’s even a portable version that you can run from a pen drive. Try it, get to know it and one day it could save you a lot of time and trouble if your PC throws a wobbly…

Conquer Your Colour Scheme

I get a lot of emails and letters asking why the colours in printed photos sometimes don’t match what’s on the screen? Sometimes it’s the printer, but more often than not it’s simply that the monitor hasn’t been properly set up. Monitor calibration is essential if you work with graphics or photo editing software but how many of us ever take the time to adjust our monitors, apart from twiddling the brightness and contrast controls? Not many, I bet, but there’s no excuse any more. A freeware program called Calibrize takes you gently by the hand, and in three simple steps helps you to adjust your display; from start to finish it only takes around 2 minutes and the new settings or colour ‘profile’ is then saved and applied every time you start Windows. It’s also handy for those who, like me, use two monitors, making it easy to accurately match the two displays.

Space on the Tray

I have to say that if you feel the need to install this little application on your PC, then you probably need a larger hard disc drive. Tray DisK Free sits in the System Tray – next to the Windows clock — and it does just one thing, it displays the amount of free space left on your disc drive. If you hover your mouse over the icon there’s a more detailed analysis. Nominally it’s set for your main drive (usually C:) but it can be set to monitor any drive on your PC. The menu option lets you change how frequently the program checks the drive, and if you want to have a fiddle with some command line switches, you can change the display and text colour.

Wi-Fi On Radar

Here’s a wireless utility with a difference. The Xirrus Wi-Fi Monitor generates a radar-like display to show all of the wireless networks in range of your laptop. By translating relative signal strength into range it shows, in a rather eye-catching way, which ones are likely to give you the best connection. For obvious reasons – unless you have a rotating and highly directional Wi-Fi antenna on your PC the display cannot tell you which direction the access point actually is, but it looks great. Versions of Wi-Fi monitor are available for Windows Mac and Linux, and the only catch is the XP version requires that you install Yahoo Widget Framework, which adds another 15Mb to the download, (the Vista version installs as a sidebar Gadget)
