Raid explained

April 30, 2009

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.

I just ran across a video on YouTube which is just as good at describing what RAID is all about. See the full story and video HERE

Whatever happened to the BumpTop Desktop?

January 4, 2009


Video: YouTube

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

Memristor

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.

Weird Microsoft Stuff

April 20, 2008

3 interesting idiosyncrasies re Microsoft that I found while surfing the net recently. 2 out of the 3 worked on my Windows Vista machine with Office 2003. See how they work for you.

1. CON is not allowed as a folder name

An Indian discovered that nobody can create a FOLDER anywhere on the computer which can be named as ‘CON’.

See if you can create a con folder on your PC.

This is not really a bug and Microsoft do know about this. It goes back to the DOS days and reserved filenames.

Below are other reserved names.

CON
PRN
AUX
CLOCK$
NUL
A:-Z:
COM1
LPT1
LPT2
LPT3
COM2
COM3
COM4

KEYBOARD AND DISPLAY
SYSTEM LIST DEVICE
Auxiliary device, usually a serial port
System real-time clock
Bit-bucket device
Drive letters
First serial communications port
First parallel printer port
Second parallel printer port
Third parallel printer port
Second serial communications port
Third serial communications port
Fourth serial communications port


2. Notepad Bug

1.) Open an empty notepad file
2.) Type “Bush hid the facts” (without the quotes)
3.) Save it as whatever you want.
4.) Close it, and re-open it.
is it just a really weird bug? :-??

3. =rand (200, 99) bug

This is a strange bug. At Microsoft the whole Team, including Bill Gates, couldn’t answer why this happened. It was discovered by a Brazilian. Try it out yourself.

Open Microsoft Word and type
=rand (200, 99)
And then press ENTER and see what happens.

Firefox releases Version 3 beta 3

February 13, 2008

Firefox 3

Firefox has just release beta 3 of Firefox 3. Confused? Well it is the third beta release of version 3 and its seems not too bad except that some plugins don’t work yet as well as some sites not displaying properly too.

I would imagine it wont be long before all the problems are fixed and I would be pretty keen to jump right in and use it, but for now I’ll stick with version 2.

You can download version 3 at the link below, and also get the full details of the new version as well.
