Moore's law is the observation that the number of transistors in a dense integrated circuit doubles approximately every two years (according to Wiki). It is nowadays the case that it applies to most of the technology space.

In 1997 the fastest supercomputer in the world was the ASCI Red. Capable of 1.8 teraflops, it was the size of a tennis court and cost $55m. In 2005 Sony launched the Playstation 3. It was capable of 1.8 teraflops too, was $500 and was the size of a phone book.

The landline telephone was invented in 1878 and took 75 years to reach 100 million users worldwide. The mobile phone was launched in 1979 and took 16 years to reach 100 million users. Candy Crush was made in 2012 and took 15 months to reach 100 million users.

I have witnessed a weekend attack cause a £45,000 loss to a business and all this is straight off the bottom line. 

This is an interesting article, which toys with the importance of password security. You need it everywhere: On your personal online banking, on your internet activities in general, on your company IT and telecoms setup....... everywhere.

Moore's Law is proving to be quite accurate as a rule of thumb. Your safe password today will be easily compromised by the computers of tomorrow. Can you afford to be relaxed about it?
