Touch Screen Displays

Writen by Kent Pinkerton

A touch screen display is a touch sensitive input device that performs both the functions of the video display unit and the input devices (keyboard and mouse). Touch screens have been very popular in the past few years and we can see them all over malls, airports, fast food restaurants, and ATMs.

Touch screen technology has been around since the 1970s and there are several companies that manufacture touch screen equipments. A touch screen saves a lot of space and maintenance and this has made them popular for information kiosks. These touch screen displays come either in the form of touch screen monitors or add-on panels that are fixed over a regular display monitor.

A touch screen display has three primary components that allow it to function: the touch sensor, the controller, and the software driver. The software driver is the application program that transcribes touch sensations into commands and communicates with the operating system installed on the computer. The controller is a PC card that connects the touch sensor to the PC. It is a small gadget that translates information from the touch sensor into information that is comprehensible to the PC.

There are several touch sensitive technologies applied in manufacturing touch-screen displays. The display can be based from resistive, capacitive, or surface wave sensory technology. A resistive touch screen display is one where a thin metallic resistive layer acts as the main sensory layer. The layer poses resistance to touch and transmits it as an electrical pulse. In contrast to this, the capacitive touch screen display uses the capacitive tendency of the human body to cause interference in its own capacitive layer and sense touch. The other alternative, the surface wave touch screen, uses ultrasonic waves. These waves pass over the touch panel. Some waves are absorbed when a user touches the screen. This wave alteration registers the touch event and the location.

Touch screen technology uses advanced principles of physics but the touch screen simplifies communication tremendously. With user-friendly operation and an attractive interface, touch screen displays are highly preferred for games, training, and at information desks.

Network Security Journal Guide

Writen by Mansi Aggarwal

The term ‘Virus’ has not just created havoc in life of living beings but also in the world of computers. Though the two kinds of viruses are completely different from each other yet both can prove extremely fatal.

Virus in computers can be defined as a program or a piece of code that is loaded onto your computer without your knowing it and it runs against your wishes. The computer viruses are manmade and can easily replicate themselves. A simple virus can duplicate itself time and again and it is quite easy to produce. Even a simple virus can swallow the entire memory of your system and stop it’s working while a slightly more dangerous or strong virus can transmit it across networks and bypass the security systems. Viruses can be transmitted as attachments to an e-mail note or in a download file, or be present on a diskette or CD. Some viruses cast their effect as soon as their code is executed; other viruses lie inactive until circumstances cause their code to be executed by the computer.

But gone are the days when viruses and diseases caused by them were left untreated. Just as people have developed cures to protect themselves, they have also invented something to safeguard their computer against the devastating threat of virus. The device that is meant to detect virus is called anti-virus.

An anti-virus program can be defined as a utility that searches a hard disk for any known or potential viruses and eliminates any that are found. Anti-virus software comprises of computer programs that attempt to identify, obstruct and eradicate computer viruses and other harmful software.

Every anti-virus software functions according to two techniques with a special focus on the first one -

(1) Examining i.e. scanning files to check familiar viruses that match the definitions in a virus dictionary.

(2) Identifying any malfunctioning software that indicates infection. Such analysis includes data captures, port monitoring and other methods.

While examining any file, the anti-virus software refers to a dictionary of known viruses that are already identified by the authors of the anti-virus software. The moment the code of a virus matches with the virus detected in the dictionary, the anti-virus software at first tries to repair the software by removing the virus itself from the file. If the virus is not removed at this stage then the software quarantines the file in a way that file remains inaccessible to other programs and the virus ceases to harm the system any more. Finally if the virus still continues to exist, the software deletes the infected file.

In order to function correctly and in a right manner the virus dictionary approach needs regular updates that involves downloads of updated virus dictionary entries. The anti-virus software that works in accordance to a dictionary typically scrutinizes files and spontaneously detects a virus when the operating system of the computer creates, opens, and closes or e-mails them. However a System Administrator can program the anti-virus software to examine or scan all the files on the user’s hard disk on a routine basis.

Conversion of Spreadsheet Graph data to SVG

Writen by Peter Hale

It should be possible to convert spreadsheet graph data to SVG (Scalable Vector Graphics). This could also be achieved in any software system that uses graphs. It is difficult to convert one structure to a different representation such as a tree based information structure of a component into a diagrammatic representation of a component in SVG. This is not impossible though as CAD tools can do this. But output of a graph to SVG is straight forward, as the actual structure and semantics are the same, its only the syntax that needs conversion, so this can be achieved using virtually any programming language. In spreadsheets the data is converted to a graph automatically anyway.

However it is not practical to expect users to do this, its much more sensible to provide this functionality for them, so they can concentrate on representing the graph to explain the information they want displayed. There might be graph types that are difficult to translate, but a good approach would be to first automate the translation to bar charts, line graphs, and pie charts.

If anyone has worked on this can they let me know, and I’ll add an explanation of what they are doing to this article.

It would also be interesting to know whether anyone is aware of whether Microsoft are going to provide an HTML output that conforms to W3C recommendations for XHTML so the converted pages can be validated. This is another straight forward problem, and would save everyone so much time. Another thing that would save a great deal of peoples’ time is a tool to aid in conversion of non-compliant web pages to compliant pages.

I am a Researcher in the final year of my. I specialise in applying Semantic Web techniques. My current research is on a technique of ‘User Driven Modelling/Programming’. My intention is to enable non-programmers to create software from a user interface that allows them to model a particular problem or scenario. This involves a user entering information visually in the from of a tree diagram. I am attempting to develop ways of automatically translating this information into program code in a variety of computer languages. This is very important and useful for many employees that have insufficient time to learn programming languages. I am using the Protege ontology editor developed from a project of Stanford University and beginning to use the Jena tool of Hewlett-Packard. I am looking to research visualisation, and visualisation techniques to create a human computer interface that allows non experts to create software.

Graphics Cards

Writen by Kent Pinkerton

A graphics card is the part of a computer which enables the computer to convert logical information into viewable images or signals that can be viewed on displays like computer monitors, LCD or projectors. The central processing unit (CPU) sends information about image to the graphic card. The graphic card then processes the information and sends it to the monitor to produce the best possible viewable image supported by its specifications. They are also known as video cards, graphic adapters and graphic controllers etc.

A graphic card has complex functions. It is connected to the motherboard, monitor, processor, and memory and works in coordination with all these components. Some graphic cards have additional connections for TV, analog and digital cameras. These days graphic cards are usually available as integrated in the motherboards, but add-ons are also available.

There are many kinds and brands of graphic cards. While selecting a graphic card, one should check out the CPU speed. A graphic card is good only as long as the CPU speed can support its functions. One also needs to check whether specifications of the computer are compatible with the graphic card. The specifications of a graphic card decide the quality of image produced such as the colors it can display, number of pixels and so on. For basic use of computer like typing, browsing or simple games, graphic cards integrated in the motherboards are quite sufficient. Advanced and high memory graphic cards are required for high end gaming, fast internet surfing for easy download of pictures and designers with lot of 3-D work. Computer games are also becoming complex and 3D in nature and so are the graphic cards to support them. To upgrade, old graphic cards can be replaced by new ones easily by anybody. In some graphic cards, there is a possibility of adding more memory without changing the card completely.

Thus, what we see on a computer is actually courtesy of graphic cards. Without a graphic card, we would just be looking at dots known as pixels. The specification of a graphic card finally decides what happens to these pixels and the quality of the final output.

What is Spyware (and Ad-ware)?

Writen by Mark Berger

Although this is a fairly basic question, not everyone is aware of exactly what spyware or ad-ware is. Spyware, usually in the form of cookies or server-side code, installs itself into your browser while you are visiting a certain website. It can also get onto your PC from peer-to-peer file sharing programs like Bearshare, Kazaa, etc. And did you know that Microsoft have actually put their own ad-ware program into Microsoft Windows?

I bet you didn’t. If you are getting annoying windows-like popups (and you just re-installed windows or formatted) that say how to stop popups, etc. Then you need to consult my article on how to disable Window’s built in ad-ware service.

Why ad-ware and spyware was invented is simple. For as long as their has been privacy, there has been those that mean to invade that piracy. It is a never ending cycle, much like how good battles evil. Companies that produce spyware usually have bad intentions. After all, how can software that resides on your PC monitoring what you do, or trying to access your personal information, be used for a good cause?

It most certainly is not. When you think about it, Spyware certainly could have been made as a preventative measure. Like helping police find pedophiles and logging their steps. Whether it was invented for good or evil, spyware will collect your personal information and sometimes attempt to transfer it without your knowing. If you think you have spyware or ad-ware, refer to my article on getting rid of it.

Ad-ware was created as an extension of online marketing. Likely some online marketing gurus were looking for another way to reach their users. You may remember programs that were popular some time ago, ones that you made money on by surfing the ‘net. I myself never made a cent on them, but the way you were paid was through advertising. A small banner would change ads rapidly at the bottom of your screen. The thinking behind this program was you clicked on an ad, and that company you clicked on paid the company who’s program you were running money per click. In other words, say you were using Company 45’s “Make money by surfing the ‘net” program. Company 45 displays random ads across your screen at the bottom. You click on company 1402’s ad, so company 1402 pays 45 for that click. And for every click on the ads at the bottom, company 45 collects revenue per click.

The thinking behind this model is you will visit these websites, possibly buy something, become a regular forum poster, whatever. No matter what, by visiting their website you are another user who contributes to the revenue to that site (or not). Although this method of traffic generation is simple, it was one of the first PPC (Pay Per Click) models on the Internet. (If you’re into Internet marketing, you’ll know this method of PCC is ineffective because the traffic is completely non-targeted).

Anyways, ad-ware works a lot like this model. A company is paid money to get the software onto your PC and then display the ads on your box. A very small percentage will actually visit the URL that appears in the ad-ware dialog boxes, so either the company displaying the ads makes the money through PPC or cost per million (CPM). CPM means every million ads displayed, the company makes a certain amount. PPC is a more effective model, but likely these companies are paid CPM because very very few users will click on the ads. This way the company displaying the ad makes money just by displaying it.

And that’s the skinny on ad-ware and spyware, and where they come from. Feel free to use this article on your website.

ERP Software Financing: the Future? – Overview for Company Owner

Writen by Andrew Karasev

In our case – we serve Microsoft Business Solutions ERP and CRM products: Microsoft Great Plains, Microsoft CRM, Navision, Microsoft RMS, as well as we do customization and integration to these products. We would like to share with you our experience with financing through Microsoft Financial Corporation, the entity handling software financing for Great Plains, CRM, Solomon, Navision & Axapta.

0% interest financing. Well – this is probably a dream or something that should not be practiced (otherwise you compromise MRP list price). However, considering the nature of software – this is something that costs nothing to sell – assuming that all the software development expenses and costs are already behind. From time to time Microsoft Business Solutions practices this 0% financing. Right now (June 2005) new customers are enjoying this promotion

Increasing Number of Clients – who use financing. Last year we saw clients who were trying to increase their market share, by fueling their efforts with financing of all the kinds, including MBS financing. This year we see regular clients, who are using financing just to stabilize cash flow. Some of these clients have enough cash to purchase the system, but they still finance.

Car vs. House financing. This is classical American dilemma. In my personal opinion – you can not pay upfront the price of the real estate, so you use mortgage to finance you house. However, again this is my personal opinion – car financing is something you should probably stay away from, because car loses value as you leave the dealership place – you can not sell the car on your own for the same or similar price. Software is very challenging asset – from one side – ERP might be something your business get he market value on, from another side – if it is not implemented or implemented only half of the way – it might be the burden. Maybe you, as business owner have to do your homework long evening and weekend hours to decide on your MRP financing.

Consulting Paradox. This is something I would prefer to keep silence about and tell when I face to face with the prospect. You can finance not only the software, but also the implementation. Imagine the situation, when Microsoft Business Solution Partner gives you the proposals where Software list price is k$25 and estimated services to implement the systems are another k$25. You can finance k$50. And if you catch 0% promotion – you finance services at 0% and the most amazing fact is – MBS Partner will get the money upfront from Microsoft Finance Corporation for both pieces (k$50)

How to trade your system in? if you or MBS partner failed to implement – is it any known way to trade in the system. Well – this is the place where we would like to stress – consider first to be conservative and do not use financing

Good luck with financing, implementation, customization and integration and if you have issues or concerns – we are here to help! If you want us to do the job – give us a call 866-528-0577 or 630-961-5918! help@albaspectrum.com

Versals & Typography

Writen by Debbie Jensen

The better a person understands software, the more flexibility there is when designing with typography especially when it comes to versals. According the Google’s dictionary, versals are the “oversized initial letters usually colored in red or blue and characterized by exaggerated curves, vertical strokes, and serifs (also called Lombardic Capitals).” To clarify, graphic designers not only have an oversized letter start out the body of text, but they make the text wrap around it too. Any given software tool can be the single answer to polishing up an awesome design. This is why graphic designers need to thoroughly understand the tools in which they work with. To get the desired professional look for their layouts, they have to thoroughly understand software tools first.

Graphic designers can learn from the stage play called “Lion King.” The play has unforgettable stunning colors and perfectly orchestrated choreography. Everything about the play was artistic and cleverly done. In addition, the music perfectly harmonized with the stage play too. Amazingly, layers and layers of information were presented harmoniously as the audience watched in admiration. From this, graphic designers can learn the importance of orchestrating and fine-tuning as they bring together all the required information for their layouts. In theory, it sounds easy, and if measuring the “Lion King” to the challenge of a layout, it is easy comparatively. At times, I wonder how I am going to organize my racing thoughts as I attempt to pull my projects together. But, I try to stay mentally organized by dividing up my ideas which helps me to organize my thoughts. Then, I methodically and strategically put it all together.

For instance, when starting a layout, I first try to pinpoint what my message is going to be and determine who is going to be my audience. Next, I start thinking about the design elements such as the heading and subheadings, the versal, graphics, and color scheme. Usually, the versal is one of the last design decisions I make for a layout. It seems that a versal to a layout is like the icing on the cake.

If you are not sure if you have made your versal correctly, show your layout to others or open up some books and magazines and make some comparisons. In fact, you should always solicit critiques and feedback from your peers. Everyone seems to see and interpret information differently, and artists should welcome feedback because of this. You’ll find with every versal you make, it’ll get easier. Nothing beats time and experience. (revised 2/14/2006)

Website Design Software

Writen by Kristy Annely

Much consideration has to be given to your website design if you want to do business on the Internet through the use of an e-commerce website. This is because it is the overall design of your website that can either provide a pleasing or disappointing experience to your visitors.

The Design of Your Website

Website design refers to the graphic makeup of the site itself including your web pages, usability, interactive applications, and level of user interface as perceived by your visitors. For this, you can either hire a web development firm to build you a website complete with hosting and maintaining services, opt for the services of a fee-only web designer, or download website design software from the Internet.

The website design software is a tool used for creating web pages tailored according to your preferences. The features that the software comes equipped with can vary, although the fundamental features include drag-and-drop image selection, web templates, layouts, graphic effects and animations, incorporate colors, customizable fonts, and even free website designs among others – indeed, the software is designed for building professional-looking websites in an instant.

But before you can go all out in building your website with your web design software, it would be best to know the basics of a website first.

Nuts and Bolts of a Website Design

Homepage

This is referred to as the main page or window of your website, and reflects the site’s entire content at best. You can design your homepage depending on the tools available in your website design software: animations, speakers and essential Flash effects, links directing to the lower pages, colored graphics, logos, and more.

Inner Pages and Landing Pages

Linked directly from the homepage, it is on the inner pages and landing pages that you will find the products and services offered on the site. While others use their lower pages to put their contact info, references, and site resources among others.

Navigation

Website navigation can vary depending on the structure of the site. You can find embedded links, breadcrumb trails, drop-down buttons, pop-up navigation bars, and other web buttons available on the site. Here, it has to be well constructed and user-friendly because the tools are your visitors main avenue to navigating and discovering the rest of your website.

Modifying Standard Shapes in Photoshop

Writen by Gabriel J. Adams

Have you ever wondered how someone was able to create a logo that looked so perfect? I used to think that someone probably had to draw the logo by hand, but then I learned some very interesting things about creating shapes in Photoshop. I used to think that you could only create standard shapes like ovals, rectangles, squares, and circles. However I recently learned that Photoshop gives you the ability to take these standard shapes and modify them to make new shapes that are very appealing. The way that this is accomplished is by selecting the path of the shape and manipulating it to create a completely new and different shape.

The first thing that you need to do is create a shape like a rectangle or an oval. Then choose the direct selection tool (white arrow), and select the path around the shape. You will know that you have selected the path, because you will see anchor points at the corners of the shape. Once you see the anchor points you will be able to click the anchor points and use them to resize and redesign the shape. The best thing about using paths to change the shape’s design is that the shape maintains its crisp lines, and looks just as good as a standard shape. How are you able to do this? The reason these changes are so clean is that the shape is vector based, and not pixel based, so you are able to just manipulate the vectors that comprise the shape. Another great thing about editing a shape in this way is that whatever formatting you have used on the shape will not be affected by modifying the path. If you have a gradient fill on the shape it will be modified as you modify the path of the shape, and it will maintain the same look as before you modified the shape. Now that you know how to modify the path of a shape you are no longer limited by the standard shapes that appear in the tools palette. Use your freedom wisely, and take this new found knowledge to you computer so you can create graphics that everyone else will envy for a change.
