We restored the operating system of our virtual machines on Wednesday, which is crucial to troubleshooting a computer. If a program that has recently been installed is causing issues with the computer, but simply uninstalling it does not solve the issue, a system restore can be performed in order to set the computer back to a previous state - one before the software was installed. At first this would cause concern about the files saved on the computer, but the system restore tool does not affect saved files; only what programs have been installed and uninstalled on the system. This saves the user from having to remake all of the files that would normally have been removed.
We learned about how severe red/green colourblindness can be and how it would affect someone using a website with the condition. There are several ways to make things easier to see for someone with this disability, one of them being to use a different CSS (Cascading Style Sheet) file for those who tell their browser to use it.
Another disability that severely affects computer users is dyslexia. More often than not, most fonts that are easy for non-sufferers to read and understand will be significantly more difficult for a sufferer to read and understand. The same can be said for certain colours; most computer monitors these days have an option programmed in to them that allows a user to tell the monitor to use a specific shade of a colour that makes large chunks of text easier to read, however not all computer users will know about this in-built feature, thus forcing web coders to use either a specific set of colours and fonts that will be easy for everyone to comprehend, or have a different stylesheet again for those who suffer from dyslexia.
In place of our Professional, Communication and Digital Skills lecture we had a woman come up from the main campus on Infirmary Road and show us how to use the resource finding tools that the college provides. This is incredibly convenient and well-timed considering we are being given a large assignment next week that will require us to use this service that is very similar to Google Scholar.
Arrays came up in programming. They're pretty much just fancy lists that start at 0 as opposed to 1, which is illogical - though I guess it wouldn't be the same if programming followed the logical conventions of society.
