In addition to the last article...Adblock
Following on from the last article about removing those irritating adverts I recently was told about Adblock.
Adblock is a free plugin that is available on on all common internet browsers. It blocks out almost all adverts automatically! You can now, for comical effect, add cats to replace the sections of the page where the ads would have been. In my opinion this is probably one of the best apps that has ever been developed for this web browser.

Remove almost all spam and advertising from the internet.
Block out Unwanted adverts when browsing the internet and watching videos on Youtube!
I found these interesting instructions about using the hosts file to block unwanted IP addresses so that when you are browsing the internet your not always plagued by annoying adverts.
When I tried this out it even prevents some youtube advertisements! Although it doesn't obviously sensor you from all of it as there are literally millions of advertising sites!
Anyway here is the link follow the instructions carefully if you do attempt this.

Make sure that if your using Vista or 7 you have to open the file as an admin (as it says). You can only save the file by opening hosts from notepad otherwise it will only let you save it as a .txt if you 'open with'.

Guiard’s model of bimanual skills
What is it?
This identifies and examines the roles and actions of the preferred and non preferred hands otherwise known as the dominant and the non dominant hands. It basically says that both hands work differently to each other when undertaking tasks.
Why must it be considered when developing HCI?
All HCI that is designed must be designed so that it can be easily used for both left handed and right handed people. A mouse for example has the option to change the right & left click buttons around if a user is either left handed or right handed.

Luminance
Brightness
Perceiving brightness forms another aspect of visual perception. Brightness is a subjective reaction to levels of light and is affected by the amount of light emitted by an object. This is known as luminance. Visual acuity increases with increased luminance. Eye is exponential in sensitivity (so something that looks half as bright is in fact 10 times less bright - this is why photos in low light are not as good as what we see).
The 3 colours in the trichromatic system are identified by 3 cells in the retina of the eyes (receptors). Theories have been developed that receptors take signals which take the form of red-green, yellow-blue and black-white. These types of signals are known as opponent colour channels because they transmit opposite colours. To display the best detail luminance contrasts should always be used.

Replacing A LaserJet Printer toner cartridge.
Here's a few tips on replacing your printers toner:
1. On the menu of the printer navigate to ‘Replace Toner’.
2. Selecting the desired toner from the menu will make the printer move the toner to the inside front of the printer.
3. By opening the printer door and lifting up the handhold gently dislodge the cartridge for removal.
4. Remove the new cartridge from the packaging and shake gently. Make sure that you remove all the packaging such as the protective tape.
5. By aligning the cartridge with the arrows you can push down gently and make sure that its locked in place.
6.Close the front panel of the printer and print a test page.

UML
Introduction
UML stands for unified modelling language. The UML has nine diagrams that account to it these are Use case diagrams, class diagrams, object diagrams, sequence diagrams, collaboration diagrams, state chart diagrams, activity diagram, component diagrams and deployment diagrams.
Advantages and Disadvantages of using UML
Advantages
•Abstraction will only focus on the information that is relevant at the time and so it will not confuse the entire project.
•Modelling will provide the information that’s between views consistent, so if something is missing it will be visualised and not be seen on another model which will contain its own unique information.
•If there are a lot of classes in the project and other people are involved in the development process then instead of them having to look through all the coding line by line they can look at all the class diagrams and dependencies.
Disadvantages
•It takes quite a lot of time to make sure that the program is in sync with the code.
•To use the most efficient UML software it costs money and takes time for someone to learn how to use it properly.
