About 12 years ago I went to work with an international company in Sydney, Australia. I was a young IT guy and had only been in IT for about 6 years at the time and had mostly worked on desktops and small microsoft networks.
While working there I met a number of experienced IT people and gained a vast wealth of knowledge and I am greatful for the experience that I gained. One of the people that I learned a great deal from was the Lotus Notes administrator. I once asked him what was this RAID thing all about, he pointed me to a document that he had created in one of the company help databases and I instantly had a working knowledge of RAID.
An excerpt from Wikipedia below describes where the name RAID came from.
“RAID is an acronym first defined by David A. Patterson, Garth A. Gibson and Randy Katz at the University of California, Berkeley in 1987 to describe a Redundant Array of Inexpensive Disks, a technology that allowed computer users to achieve high levels of storage reliability from low-cost and less reliable PC-class disk-drive components, via the technique of arranging the devices into arrays for redundancy.”
“More recently, marketers representing industry RAID manufacturers have revised the term to Redundant Array of Independent Disks, a convenient means of avoiding the expectation of low cost associated with the term inexpensive”
This video below should give you an idea of what RAID is all about.

Whatever happened to the BumpTop Desktop?

About 1 and a half years ago the BumpTop desktop was featured on Ted Talks. Now I haven’t heard anymore about it, I wonder why it seems to have paled into insignificance.
Scientists create first Memristor: Missing fourth electronic circuit element
May 1, 2008
In an exciting breakthrough, scientists from HP Labs have built working prototypes of a new electronic circuit component called a ‘Memristor’. The device may lead to instant-on PC’s and analog computers that act in the same way a human brain does.
Until recently the Memristor had only been described using mathematical equations written back in 1971 by engineering student Leon Chua. Although Chua knew this circuit element should exist, he was unable to come up with a physical manifestation of the component.
“Thirty-seven years later, a group of scientists from HP Labs has finally built real working memristors, thus adding a fourth basic circuit element to electrical circuit theory, one that will join the three better-known ones: the capacitor, resistor and the inductor.”
The researchers believe this discovery may be integral in the production of Instant-on PC’s and more energy efficient computers and even computers that act in the same way as the human brain.

“This water based cooling system supports memory in dual channel and has an ultra slim pump and water tank. The radiator is based on a flip open design and has a 5cm fan for keeping the temperatures down.”
“The system features two heat spreader units with allow the liquid inside the system to move the heat away as quickly as possible. ‘Cool Rain’ is pretty stylish and the blue LED is the icing on the cake. Though it may look complicated Cool Rain is very easy to install and supports single / dual sided RAM alike.”

How some major computer companies got their names
January 27, 2008
Here are some of the names you would know as the most well known computer companies in the world, but how did they get their names? See below for the answers.
“It was the favourite fruit of founder Steve Jobs. He was three months late in filing a name for the business, and he threatened to call his company Apple Computers if the other colleagues didn’t suggest a better name by 5 O’clock.”
“It is not an acronym as popularly believed. It is short for San Francisco.”
“This name was formed by using COMp, for computer, and PAQ to denote a small integral object.”
“The name was derived from the founder’s name Dr.Michael Cowpland. It stands for COwpland REsearch Laboratory.”
“The name started as a joke boasting about the amount of information the search-engine would be able to search. It was originally named ‘Googol’, a word for the number represented by 1 followed by 100 zeros.After founders – Stanford graduate students Sergey Brin and Larry Page presented their project to an angel investor, they received a cheque made out to ‘Google’ ”
“Founder Jack Smith got the idea of accessing e-mail via the web from a computer anywhere in the world.When Sabeer Bhatia came up with the business plan for the mail service, he tried all kinds of names ending in ‘mail’ and finally settled for hotmail as it included the letters “html” – the programming language used to write web pages. It was initially referred to as HoTMaiL with selective uppercasing.”
“Bill Hewlett and Dave Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett.”
“Bob Noyce and Gordon Moore wanted to name their new company ‘Moore Noyce’ but that was already trademarked by a hotel chain so they had to settle for an acronym of INTegrated ELectronics.”
“Mitch Kapor got the name for his company from ‘The Lotus Position’ or ‘Padmasana’. Kapor used to be a teacher of Transcendental Meditation of Maharishi Mahesh Yogi.”
“Coined by Bill Gates to represent the company that was devoted to MICROcomputer SOFTware. Originally christened Micro-Soft, the ‘-’ was removed later on.”
“Founder Paul Galvin came up with this name when his company started manufacturing radios for cars. The popular radio company at the time was called Victrola.”
“Larry Ellison and Bob Oats were working on a consulting project for the CIA (Central Intelligence Agency). The code name for the project was called Oracle (the CIA saw this as the system to give answers to all questions or something such). The project was designed to help use the newly written SQL code by IBM. The project eventually was terminated but Larry and Bob decided to finish what they started and bring it to the world. They kept the name Oracle and created the RDBMS engine. Later they kept the same name for the company.”
“It originated from the Latin word ‘sonus’ meaning sound, and ‘sonny’ a slang used by Americans to refer to a bright youngster.”
“Founded by 4 Stanford University buddies, SUN is the acronym for Stanford University Network. Andreas Bechtolsheim built a microcomputer; Vinod Khosla recruited him and Scott McNealy to manufacture computers based on it, and Bill Joy to develop a UNIX-based OS for the computer.”
“The word was invented by Jonathan Swift and used in his book ‘Gulliver’s Travels’. It represents a person who is repulsive in appearance and action and is barely human. Yahoo! Founders Jerry Yang and David Filo selected the name because they considered themselves yahoos”
