Eliminate slow Broadband due to faulty BT Line
If you have a slow ADSL broadband the first thing to do is eliminate a faulty line coming to the building. The best way to test this is to run a Quite Line Test. This test is not the most scientific and relies on the sensitivity of the human ear. However your ear is very good at picking up noise interference when it is supposed to be dead quiet.
This test pin-points interference between the Exchange and Master socket (the demarcation entry point into the building).
Use Windows Check Disk to Repair Your Drive
Sometimes, your computer is noticeably slower or programs “hang” when you access certain files or upgrades fail or programs just won’t run. This odd behaviour might occur because there is corruption of within the files system on your hard disk drive.
You can troubleshoot the problem by using the Windows Disk Check tool called CHKDSK. Check Disk can identify and automatically correct file system errors and make sure that you can continue to load and write data from the hard disk. You can use Check Disk in all versions of Windows not only for local hard drives,

WordPress Paste Snapshot Images Work-around
I have tried various image paste WordPress Plugins but always come across some drawback or other. Imagepaste works well but puts the image in wp-content\uploads with an unrecognisable random file name and does not add the name to the Media library. Image-elevator looks good but forces you to use the premium (paid for) version to get any real value out of it.
However I have discovered a work-around in Kubuntu using the fantastic KSnapshot screen capture program. This allows you to drag and drop the snapshot image directly into WordPress.
Windows “Checking for updates” never ends
After installing a new copy of Windows 7 SP1 the first Windows Update can take several hours “Checking for Updates…” and appears to be hung. However, don’t give up. It is processing over 200 updates! The time it takes to complete depends on the speed of your Internet connection and computer. Times can be up to 1 hr.
To avoid the frustration of waiting try to run this first update overnight. Ensure you have set Disk Sleep to “Never” within Control Panel | Power Options to avoid it sleeping mid-way through.

The Right Way to Clean a Flat Screen Monitor
Prepare the Screen
Turn the monitor off. Do not clean a screen until it is cool. Remove as much dust from the screen as possible without actually touching it, e.g. vacuum or blowing . Use a soft lens brush to remove stubborn dust. Lightly wipe the screen with a dry and clean microfiber cloth. Shake out any dust from the cloth between wipes to avoid rubbing dust into the screen and scratching it. Don’t use paper towels,
AirPort Roaming Network Configuration
The above diagram shows a home Airport network with wired (RJ-45) Airports in the Sitting room, Reception (Time Capsule) and Study (Loft) and a wirelessly connected Airport in the Conservatory connected to a HiFi system using a audio mini-jack port. Due to the proximity of the Airport HiFi it wirelessly connects to the nearest AirPort Time Capsule in the Conservatory.
