A person who works on the move is called a digital nomad. Such a worker may or may not be on the rolls of a company, and could be a consultant/freelancer/a writer on the move. They are persons with a free spirit who like a remote lifestyle and earn as they move, and believe that with discipline and the correct technology, they can be as productive as a person sitting in office. This is new tribe of people and for them, the economic downturn has brought little distress as companies turn to part-timers to save on costs.

Digital cleanse is a term mooted by John Mayer, musician and avid blogger and tweeter, as a resolution and challenge for the first week of 2010.

The basic idea is to unplug and meet people.

Captcha refers to Completely Automated Public Turing Test to differentiate between computers and humans. A Captcha Security Code is an image of letters that a person must type in to match the Captcha image they see. It is a type of challenge response test used in computing to ensure that the response is not generated by a computer. This code was created to stop automated computer spam robots from filling out forms and harvesting email addresses and then sending out spam emails. Only a human can type out a code he sees correctly, an automated computer programme cannot.

Email apnea is the stress caused by the inability to process emails and connect even as mails flood the inbox. It is marked by a suspension of breathing, shallow breathing or hyperventilating while checking mail. Researcher Linda Stone coined this term after realizing that many people go through this process every morning, the mind whirling from mail to mail, filing, forwarding etc. She also found the effect of this kind of apnea on general health to be negative in the long term.

The tendency, over time, for software to become difficult and costly to maintain is known as software entropy. A software system that undergoes continuous change, like new functionality added to its original design, will eventually become more complex, losing its original design structure, and may even become disorganized as it grows. In theory, it may be better to redesign the software in order to support the changes rather than build on the existing programme.
