Surveillance and Privacy
January 28, 2012 – 11:06 pm
Surveillance is more and more popular these days, and this is not good news for those who value their privacy. Once surveillance becomes more affordable, there might be surveillance almost anywhere. In such scenario people would have no privacy, and someone who had access to surveillance videos could possibly know your every move. Fortunately, there are some steps being taken in order to make surveillance more appealing to the public. There is a software that claims that it can scramble the face of the person, so that it will only be visible for those in charge of the software when they will spot some suspicious behavior. When they notice something suspicious, they will have the option to remove blurring. This way they will not be able to recognize other people passing by. However, we would have to trust that their supervisors would not allow them to remove the blurring without a good reason. It sounds good, but it implies that you can trust all security guards and their judgment. I know that many people will still not be completely satisfied with this software, but we have to admit that it is a step in the right direction. If surveillance is something we cannot avoid, we should at least make sure that it does not violate our privacy too much.
Many of us have heard the term Page Rank on numerous occasions, and we usually heard it many times. But what does it exactly mean? How is it calculated? While some of this is a public knowledge, I will try to explain what this mysterious Google Page Rank is, and how it works in a few sentences. Google’s Page Rank is the way Google evaluates which site is more important than others, and how popular this particular website is. The higher Page Rank, the more visitors you will usually receive from Google’s search engine, as your website will often appear higher in the search results. The calculation is based on the number of votes other sites “cast” on a website. Vote means simply a link put on another website to a website for which a Page Rank is calculated. Generally, the more links pointing to your sites, and the more of them coming from sites that have high Page Rank themselves, the higher your Page Rank will be. While Page Rank is in no way the ultimate ranking system, and should not be viewed this way due to numerous flaws, is it considered to be quite important to many webmasters. One of the reasons it is considered so important is that there are very few ranking systems to begin with.
What is the most important component of the computer? Many people when asked what computer they have mention computer components such as processor, RAM, and HDD. While all of those components are very important, I am going to risk saying that the motherboard is the most important component. Motherboard is so important because all other components connect to it. That is why the motherboard determines what kind of components will you be able to put into your PC. Different processors, RAM, or graphic cards will not work with all motherboards. It is my recommendation that you buy a motherboard that supports all of the other components you may plan to buy in the future. When buying your motherboard you should think what components you may want to upgrade within the next three years.
