Structured Representation of Information

The Need for Ontologies

Information is scattered within organizations and often not held in such a structured way as to be easily accessed by employees or software. This problem was examined by Lau et al (2005) using the example of McDonnell Douglas (now part of Boeing), that demonstrated how difficult it is to gather unstructured knowledge. Therefore, it is important that research is undertaken into methods of capturing, structuring, distributing, analyzing, and visualizing information.

Taxonomies, Ontologies and Structuring of Information

An ontology is a classification structure. A taxonomy can be just a convenient structure to assist programmers, or part of an overall 'thesaurus' which describes and agreements the meaning of things. This 'thesaurus' structure is the ontology and may contain one or more taxonomies. Engineers may have different names for the same thing, eg wing skin stiffeners may be referred to as stringers, but rib stiffeners are never called stringers. … Read More

How To Start A Business Without A Computer

For anyone who has wanted to start a business and says "I can not" this
article is the solution to all of your woes. For anyone thinking she does not know what she's talking about and she is full of it. Let me give you my own personal testimony.

Many, many, many moons ago in 1985 I had become quite bored and disgruntled
as a city government employee. It was unfulfilling and I knew there had to be
more to life than this. I discovered in 1997 that I was an unconventional personality type. (Before that I could not tell you what my problem was. No job ever satisfied me.) I became fascinated with computers and information. I collected all kinds of what I considered useful information. My passion for knowledge and information kept me in libraries and bookstores.

Fast forward it's 2002 and I … Read More

What to Consider When Buying a New Computer

One of the primary mistakes made when buying a new desktop computer is how much you spend.

If you spend too little in an attempt to save some money, you will likely get a machine that is not what you want or need. Economy machines, $ 300 or less, will end up costing you more to upgrade in the long run as your computer skills and needs increase, if upgrading them is even possible. Then again if you get a machine with all the bells and whistles you will likely never use the power offered and will have wasted a lot of money. This is what too many people mistakenly do in the hope that more is better. Remember computers do not appreciate in value. In 2-5 years your high end machine, which can cost well over $ 1000, will probably be almost obsolescent anyway.

Set yourself a realistic budget, … Read More

Basic Barcode Reading Technology – Scanners, Readers and Wireless

The technology used to read barcodes is relatively simple, but there is little information available for the novice. This is intended to be an introduction to the scanning, processing and presentation of barcode information.

Scanners

A scanner is a device that converts the image of a barcode into electrical pulses. There are four basic ways of doing this: contact wands, active non-contact (AKA laser scanners), and passive non-contact, which can be cameras or linear CCDs (charge coupled devices). All of these devices have similar outputs, strings of electrical pulses that mimic the white/dark and width of the bars. With the exception of cameras, a scanner will always include a light source, either LED or laser.

Wands are the simplest, but have the most limitations. A wand has a light source, focusing lens and a light detector. It has no moving parts, which makes it the most rugged of scanners, but … Read More

Computer Memory Controllers – How Do They Work?

Controller

A computer system contains a first and second memory controllers; a first and second computer memory associated with the first and second memory controllers, a memory space; and firmware under control of which the computer system generates data that enables the first memory controller to use the first computer memory, saving the data in the memory space, copies the data to the first memory controller, causing the first memory controller to use the first computer memory, and uses the first computer memory to initialize the second memory controller to use the second computer memory.

Reset

The computer firmware initiates a reset after saving the data; the computer system determines whether a current reset is firmware initiated; If the current reset is firmware initiated, the computer system copies the data to the first memory controller having the first memory controller to use the first computer memory, and uses the first … Read More

Is Your Internet Provider Blocking Your Emails Port 25 – Here’s How to Fix It

Almost a week ago I found out that I could not send emails using my desktop software such as (Outlook / Thunderbird). After speaking with my high speed internet provider I was told that they had recently started blocking port 25 – basically stopping me from sending emails.

So after speaking with the tech support staff they told me to try port 587 which did not work. So I called up my website administrator company and he said that by default it has to port 25 and like most others they only support port 25 for sending out emails.

After spending several hours researching this and trying several solutions, each crazier then the one before, I stumbled upon a solution that still allows me to send email from my computer using desktop software such as Thunderbird or Outlook.
