Computer Hardware - Desktops and Notebooks and Handhelds - Oh My
Computers have become ubiquitous in almost every facet of our lives. At work, desk jockeys spend hours in front of their desktops, while delivery people scan bar codes with handhelds and workers in the field stay in touch with the central office via their notebooks. At home, we rely on our desktops and notebooks to do our shopping, to entertain us, and to keep us abreast of world events. We may not see our email servers, but we count on them to deliver our email whenever and wherever we want it. Our PDAs keep track of our hectic schedules, our to-do lists, our contact lists, and even entertain us with games while we're waiting for an appointment or to board a plane.

Encryption Algorithms Briefly Defined
Encryption algorithms are commonly used in computer communications, including FTP transfers. Usually they are used to provide secure transfers. If an algorithm is used in a transfer, the file is first translated into a seemingly meaningless cipher text and then transferred in this configuration; the receiving computer uses a key to translate the cipher into its original form. So if the message or file is intercepted before it reaches the receiving computer it is in an unusable (or encrypted) form. Here are some commonly used algorithms: DES/3DES or TripleDES This is an encryption algorithm called Data Encryption Standard that was first used by the U.

Time To Stop
How can a society that exists on instant mashed potatoes, packaged cake mixes, frozen dinners, and instant cameras teach patience to its young? -Paul Sweeney I came across this quote today and it made me stop and think of how impatient we have become. Years ago, it took time to prepare a nutritious evening meal. Sometimes it took most of the day to shop and prepare the vegetables and the meat.

Blackberry Pearl
Blackberry Pearl is one of the latest GSM handheld from Research in Motion (RIM). It is also the smallest of the smart phones marketed by RIM. Straight into its specifications, the Blackberry Pearl is quite compact unlike the earlier RIM models.

It might take a bit of practice to get used to the keypad, but it is not cumbersome either. Another change that RIM had introduced in its slimmest smart phone is the track ball in place of the scroll wheel in its older versions.
