Every day, our wireless networks make life that little bit easier. Unfortunately, they sometimes also make life easier for devious neighbours and serious criminals. It may only be the kid next door piggybacking on our internet access, but it could be a hacker stealing our bank details or using the network for illegal activities. This article explains in detail how to keep both of them at bay.

Meaning Based Computing (MBC) is a new type of technology that’s set to revolutionise data searching both on individual computers and on networks. This software searches for information based on its subject matter – its meaning – rather than on any words or phrases that files may or may not contain. As a result, it can unearth data that existing search technologies would never find. For individuals, this is useful and time saving; for companies, especially large ones, it’s money in the bank.

When it comes to pursuing our dreams, it would be hard to find a more encouraging role model than Harry Bernstein. He had struggled in vain for most of his life to be a successful writer. In 2002, his efforts were rewarded when his first memoir was published to widespread critical acclaim. He was 96. He went on to write three more highly acclaimed books before he died in 2011 at the age of 101. This 569-word article examines his amazing achievement, the part his wife Ruby played in it, and how they both should inspire us to never give up on our dreams.

The depression is temporarily lessened by more food, thus creating a vicious circle, which is rarely broken without external help. Behaviour modification through personal coaching is a successful method for treating this problem.
