Fun Facts About The Internet

The Internet is one huge place where billions of people have fun on a day-to-day basis. To be more precise, 2.3 billion people from all over the world are using their desktop computers, laptops and from recently mobile phones and various other gadgets to access the Internet each and every day. What seems to be even more amazing is the fact that in the last decade there was phenomenal growth of over 500% when it comes to the number of Internet users. These numbers are only there to help you visualize how important the World Wide Web has become to us – it is now an inevitable part of our daily routine. So, the next time you sit behind your computer screen and connect to the Internet, know that you are not the only one who performed this task. Instead, the next time you deny the influence the Net has on you, remember that one third of the world's population is online every and every day, and this includes you too.

Internet Usage
As mentioned above, nearly one third of all the people in the world use the Internet daily for many different reasons. However, you need to pay attention to this – these numbers are not the same for every country or every continent in the world. Moreover, there is a big difference between the number of Internet users in Africa and Europe, for instance. While it has been estimated that only 4% of the population in Africa use the Internet, Europe, on the other hand, boasts a 24% Internet usage.

Do Teenagers Use the Internet Moderately?
After discussing the numbers relating to the amount of Internet users across the globe, it is also important to mention age groups. As expected, teenagers spend a lot of their free time online, but the numbers suggest that they are not the ones who spend the most time on the Internet. Even though teenagers spend approximately 30 hours a week online, young people between ages 21 and 35 make the largest proportion of Internet users. So, in case you fall into the latter category, do not tell off your kid for spending too much online. Your child has you to limit their Internet usage, and who is supposed to tell you when it is enough?

Web Cameras
Fortunately, the Internet is evolving more and more, and its users find the new technology to be very useful. When it comes to web cams, it was a long road until they became as useful they are today. In the past, web cams had a purpose, but what they were used for then were quite a bit different from the ways that web cameras serve today. Namely, the first web camera had a very unusual purpose – it was used for monitoring a coffee maker at Cambridge University. Its users found a very interesting and practical way to use a web camera, as they could see when the coffee maker was empty.

How Does Computer Animation Work?

Animation has significantly improved over the years, from the old two-dimensional cartoons of old to the amazing, and often believable, three-dimensional animation that can now be seen in many movies.

So, how does computer animation work? In a nutshell, 3D animation is created by using a computer to “give life” to static images. In other words, by quickly running through a sequence of images, a computer can appear to make static objects move. This article will explain the basics of how computer animation works.

How Does Computer Animation Work?

There are 2 types of computer animation. The first is called computer assisted animation and the second type is computer generated animation. There are differences between the two, the most significant being that computer assisted animation creates 2 dimensional, commonly referred to as 2D, images. Computer generated animation creates 3 dimensional, or 3D, objects.

The other major difference is that in computer assisted creation, the artist will draw the original 2D objects either on paper or with the help of a computer. In computer generated graphics, the computer does all of the work, since it’s not possible to create this type of dimension using pencil and paper.

In traditional animation, an artist first draws out his objects, scenes and characters in a sequence. Next, he places the most important elements of the sequence in an outline. These are known as keyframes. Each keyframe represents a significant point of time in the final sequence.

Originally, junior animators were then called in to draw the parts of the sequence between these keyframes, thus creating one continuous sequence. Creating these cells, or frames, which fill the gaps between the keyframes is referred to as tweening.

With computer assisted animation, tweening is done by the computer using advanced mathematical algorithms to create a smooth, animated sequence. In computer generated animation, the entire process is done by the computer, from the beginning drawing to the final animation sequence.

What Kind of Software Is Needed to Create 3D Animation?

Today’s computer animators use sophisticated software programs to generate 3D images and graphics. A few of the most popular 3D animation software programs are Maya, 3D Max and Poser. These programs are used by amateur animators and professional artists alike. Unfortunately, the cost of these programs is completely out of reach for the average person. Many of them cost $5000 or more! Thankfully, there are few cheaper options, including free software, available for aspiring animators to learn with.…

16 Most Inspiring Famous Failures

To succeed in business or life, I came to realize that we must continually take remedial actions. Putting myself on the line day after day can be extremely draining, especially when things do not work out as I desired. Hence, each time I face a disappointing event or undesirable outcome, I NEVER FORGET these famous failures:

1. Bill Gates, founder and chairman of Microsoft, has literally changed the work culture of the world in the 21st century, by simplifying the way computer is being used. He happens to be the world’s richest man for the last one decade. However, in the 70’s before starting out, he was a Harvard University dropout. The most ironic part is that, he started a software company (that was soon to become Microsoft) by purchasing the software technology from “someone” for only $US50 back then.

2. Abraham Lincoln, received no more than 5 years of formal education throughout his lifetime. When he grew up, he joined politics and had 12 major failures before he was elected the 16th President of the United States of America.

3. Isaac Newton was the greatest English mathematician of his generation. His work on optics and gravitation made him one of the greatest scientists the world has even known. Many thought that Isaac was born a genius, but he wasn’t! When he was young, he did very poorly in grade school, so poor that his teachers became clueless in improving his grades.

4. Ludwig van Beethoven, a German composer of classical music, is widely regarded as one of history’s supreme composers. His reputation has inspired – and in many cases intimidated – composers, musicians, and audiences who were to come after him. Before the start of his career, Beethoven’s music teacher once said of him “as a composer, he is hopeless”. And during his career, he lost his hearing yet he managed to produce great music – a deaf man composing music, ironic isn’t!

5. Thomas Edison who developed many devices which greatly influenced life in the 20th century. Edison is considered one of the most prolific inventors in history, holding 1,093 U.S patents to his name. When he was a boy his teacher told him he was too stupid to learn anything. When he set out on his own, he tried more than 9,000 experiments before he created the first successful light bulb.

6. The Woolworth Company was a retail company that was one of the original five-and-ten-cent stores. The first Woolworth’s store was founded in 1878 by Frank Winfield Woolworth and soon grew to become one of the largest retail chains in the world in the 20th century. Before starting his own business, Woolworth got a job in a dry goods store when he was 21. But his employer would not let him serve any customer because he concluded that Frank “didn’t have enough common sense to serve the customers”.

7. By acclamation, Michael Jordon is the greatest basketball player of all time. A phenomenal …

How to Remove an Autorun Inf Virus From a Computer

The article describes the procedure for removing an Autorun.inf virus from a computer. The methods compiled here are simple and correct to date. It is, however, recommended that these should be followed carefully to avoid running into problems. Since it is a time-consuming and difficult procedure, you can alternatively approach an expert virus removal support service. It will save you a great deal of time and money.

Autorun.inf virus is a dangerous program that exploits Autorun.inf, a common Windows operating system file to execute itself on removable media and other drives viz. C: in your computer. It can be quite difficult to deal with this virus as it is capable of re-executing itself after being removed. Considering this, we have designed a comprehensive guide that will help you get rid of this virus forever. See below for details.

Instructions:

Click on the Start button and browse to Run. Type 'cmd' in the empty box and press the OK button. It will open the Command Prompt window. Type 'del / a: rhs [drive letter]: autorun.inf' (without quotes and brackets and as is) and hit Enter. For example, it's the C: drive which you want to run this command for. You will type 'del / a: rhs c: autorun.inf' and hit Enter to proceed. You must repeat the command for all the drive partitions viz. D: or E: etc. When done, exit Command Prompt and reboot your computer.

If this method does not work for you and the virus still exists in your computer, exercise this method. Browse to C: drive > Windows > System32 > and Config . Look for csrss.exe, arona.exe, logon.bat, and autorun.inf files. Select and delete all of them one by one. Move to Windows (the directory) again and then the media folder, locate and delete the arona.exe file. Search through all the drives viz. C :, D :, E: etc. for the autorun.inf file and delete it. When done, close all the windows.

Open Registry Editor. Go to Run , type 'regedit' in the Open box, and hit Enter . If prompted for an admin password, you must enter it to continue to Registry Editor. When in the utility, take a backup of the registry before proceeding with registry modification. A registry is the heart of an operating system. Wrong configurations to the registry can lead to permanent system crash or other severe problems in your computer. Since, registry modification is a sensitive and cumbersome process, we recommend you to take help of a professional virus removal support service.

You can either create a system restore point or use the built-in Import and Export feature to backup and restore your registry if so required.

What Is a Legacy Computer System?

A legacy computer system is one that is outdated either in terms of hardware or software. At the time of writing, any computer running a version of Windows below Windows 7 is usually considered to be a legacy system, because this is the latest version currently available. (This also applies to computers running earlier versions of any other operating system, such as Linux)

Unlike a lot of other items, which tend to last for a long time, computers seem to go out of date extremely quickly, which can cause problems if equipment is not updated where necessary, especially within businesses.

This is because of a phenomenon known as Moore’s Law, which is the prediction that every 18 months or so, computer capability doubles.

For example, if the most advanced specification available is 1GB Ram with a 2Ghz processor one year, it would be double that value after 18 months.

I have found over the years that there are both advantages and disadvantages to using legacy systems.

One of the advantages is that some older programs will only run on older computer systems, such as some of the early games produced by various companies.

Another advantage of these systems is that, because they are so out of date, they are often cheap to obtain, and can therefore be ideal for anyone who has never used a computer before, or who only needs it for basic functions, for example word processing.

Also, although legacy systems are older, they are also normally more stable. This is because update patches are usually released once a month from when the operating system is released to around 5 years later. (This only applies to Windows operating systems)

However, using one of these systems can often mean you get left behind rather quickly if you want to run any newer games and software or use any newer hardware, such as printers or scanners, which are not always backward-compatible with older systems.

This is mainly because as hardware capabilities increase, so do the demands of any software that is created, because developers always aim to take full advantage of new technology wherever they can, to enhance the user experience.

Overall, I would recommend that you consider what purpose you need a computer system for when choosing whether to use a new computer or an older system. In other words, for reliability, choose an older system and for higher performance levels, choose a newer system.…

Technology Explained : ISO format

Many new virtual environments consider an ISO file as an additional hard drive or a CD/DVD drive. These ISO files can be created with a lot of software’s which would take there own sweet time before the user gets the final file in an ISO or BIN format.

If you are looking for reliable software which has good speed and agility, then go for PowerISO, which is one of the powerful tools used today to create such ISO files either from local stored files or directly from a CD or DVD. This image processing tool provides additional features where any user can create, open, extract, compress, split, and encrypt an ISO file. Once the ISO file has been created, it can be further used with any virtual server connection.

The application can be installed in few simple steps and provides an easy to understand user friendly interface. This tool is particularly important for system administrators who can create ISO files for there Operating System or any other application. Image creation was never that easy and these files would then be mounted as virtual drives to fit into any virtual server or VMWare environment.

You can pick and choose the files that can be stored into an ISO file by simply using the drag and drop feature. Clipboard copy-paste also works here without any problems and a user can easily create a new ISO files with 3 to 4 simple clicks.

In case you want to add additional files to existing image then you may open the ISO file using the same PowerISO application interface and using the same drag-drop or copy-paste feature to generate modified ISO image file. Well! It is now very obvious that an ISO files can not be extracted without special ISO reader application, which in our case is the PowerISO. Extract the files to any location either on local computer or over the network.

An ISO file can be stored into other different formats as well like BIN etc. there is absolutely no issue noticed or reported about storing ISO files into BIN format.

Another good feature with PowerISO allows the users to create bootable ISO files which can be burned directly on to the CDs or DVDs. In most cases they can be used to build a new virtual operating system etc. Along with that the user can also choose to create a floppy disk image as well.

Do you know: many enterprises use virtual environments to run there operating system today! They do this to save up on different hardware based server and to save up the disk space that could also be an issue in future. Thus a need to create an ISO file arises and that is where PowerISO can be used to create files using the DAA (Direct-Access-Archive) advanced image format which supports enhanced features like compression , security and spanning one image through multiple volumes (which are very similar to an ISO or BIN file format).

The application can be …

Web Application Development

In computing, a web application is a client-server computer program in which the client (including the user interface and client-side logic) runs in a web browser. Common web apps include webmail, online retail sales, online auctions, instant messaging services and many other functions. The general distinction between a dynamic web page of any kind and a web application is unclear. Web sites most likely to be referred to as web applications are those which have similar functionality to a desktop software application, or to a mobile app. Single page application are more application- like because they reject the more typical web paradigm of moving between distinct pages with different URLs.

Technologies

There are two main categories of coding, scripting and programming for creating Web Applications:

I. Client Side Scripting / Coding – Client Side Scripting is the type of code that is executed or interpreted by browsers.

Client Side Scripting is generally viewable by any visitor to a site (from the view menu click on “View Source” to view the source code).

Below are some common Client Side Scripting technologies:

1) HTML (Hypertext Markup Language)

2) CSS (Cascading Style Sheets)

3) JavaScript

4) Ajax (Asynchronous JavaScript and XML)

5) jQuery (JavaScript Framework Library – commonly used in Ajax development)

6) Moo Tools (JavaScript Framework Library – commonly used in Ajax

7) Dojo Tool-kit (JavaScript Framework Library – commonly used in Ajax development)

II. Server Side Scripting / Coding – Server Side Scripting is the type of code that is executed or interpreted by the web server.

Server Side Scripting is not viewable or accessible by any visitor or general public.

Below are the common Server Side Scripting technologies:

1) PHP (very common Server – Linux / Unix based Open

Source – free redistribution, usually combines with MySQL database)

2) Zend Framework (PHP’s Object Oriented Web Application Framework) ASP (Microsoft Web Server (IIS) Scripting language)

3) ASP.NET (Microsoft’s Web Application Framework – successor of ASP) Ruby on Rails (Ruby programming’s Web Application Framework – free redistribution)

4) Perl

5) Python

Advantages of web application development:

1) Web apps are developed with programming languages such as HTML and CSS, which are well known among IT professionals.

2) These apps run on the device’s own web browser through a simple URL.

3) They may also open websites. This means that they don’t require to be updated in the way common apps do. In this sense, it’s the website to which the application is linked that will be updated.

4) On the other hand, a web app’s development time is lower. Hence its lower price.

Disadvantages of web application development:

1) An Internet connection will be an absolute must to run it. Otherwise, you will not be able to browse the website and the web app will be of no use to you.

2) It will also lose visibility as it will not be on display in the stores.

3) In addition, there will be some access restrictions as to certain hardware features of …

Getting Started With User Experience Crafting for Websites

Okay, this is a tough topic, because it involves really hard problems and really easy problems, however I'm not here to tell you how tough it is, I'm here to give you an easy introduction to crafting user experiences.

So, first off, what do we mean by crafting user experiences? Put simply it's what users remember when they visit or use your site. It could be 'man, that site was the coolest' or 'oh, this is so buggy'.

Now, the first order of business is figuring out what you want your users to feel?

Do you want them to leave your site feeling happy? Excited? Efficient? Smart?

Second thing, who are your users? Give an age-span together with professional background. Do you know anyone like that? Excellent, go ask them when it where the last time they felt what you want your website to make them feel.

I assume that you already have a site, now take a look at that. No, really, exit this page, look at yours and return to this. Now.

First order of business, grab all the low hanging fruit. Read through all the popular material that's older than a week and look for obvious spelling-mistakes and sentences that sound strange. Remember, text is the gold standard for communication on the internet at the moment (video is quickly gaining ground though). Also check to see if your articles are up to date, it's usually better to cut than keep something that's stale.

Check to see if its easy to read and pay especial attention to contrast and fonts. Also try to increase the text-size and Google translate it to another language. If it's readable after that you have avoided the worst hurdles.

Also check to see that both images and links have alt-texts (texts that show up when you hover your mouse over them, among other things). Try to keep this text descriptive since it will be read by people with sight-disabilities and when your images stops working.

Last thing to look for is to consider button-sizes and the like. Beginning computer learners tend to use the mouse a lot and buttons and menu's should be an OK size for them.

Now, return to your friends words on what makes them feel what you want them to feel and try to incorporate that into the page. This is where it gets very, very complicated very quickly, but remember, as long as the site is clear, informative and generally works, then you can not go to wrong. …

The Working Principles Behind a Barcode Scanner

There are many types of barcode scanners available on the market as of now, and some of them are really impressive. For example, the laser scanner is a very interesting piece of equipment once you understand the principle behind it. One of the most famous alternative to laser scanners are CCD based scanners.

CCD scanners are a different kind of scanners as they don’t have any moving parts thus they’re more reliable and less prone to failure. Another type of scanner is the 2d barcode scanner which is the most popular type of scanner. You’ll see it in almost any shop, may it be a clothing shop, a hypermarket or just your regular corner street shop.

Laser scanners use moving mirrors and light diodes and are more likely to fail in a shorter amount of time, whereas CCD barcode scanners use LEDs that are known to last 10 times more than light diodes. 2d barcode scanners also make use of the CCD technology to function.

The principle behind the CCD technology isn’t in any way mind blowing – a CCD scanner uses an array of small light sensors that are pointed at the barcode section on a product. The way these scanners work is that they form a sort of grid of tiny laser like lights on the surface of the barcode part of the product. Because barcodes are usually printed on white backgrounds a part of that light emitted from the scanner is reflected to a receiver inside the head of the scanner. That light is translated into a voltage using a photovoltaic cell, and that amount of voltage corresponds to a single type of product in the store.

After the information is sent from the scanner to the computer it’s then cross referenced to a database – which is also stored on the computer – to which the scanner is connected to. All this stuff happens in a matter of nanoseconds – the reader emits a grid of laser like lights on the barcode part of the product. A part of the light is reflected back from the white surface to a receiver placed inside the head of the barcode scanner (also known as a photovoltaic cell) which translates the light into a voltage and after wards cross references it to a database to find out what product it scanned.

And that’s just how barcode scanners work.…

Teaching With Technology

Teaching with technology helps to expand student learning by assistant instructional objectives. However, it can be thought-provoking to select the best technology tools while not losing sight of the goal for student learning. An expert can find creative and constructive ways to integrate technology into our class.

What do we mean by technology?

The term technology refers to the development of the techniques and tools we use to solve problems or achieve goals. Technology can encompass all kinds of tools from low-tech pencils, paper, a chalkboard to the use of presentation software, or high-tech tablets, online collaboration and conference tools and more. the newest technologies allow us to try things in physical and virtual classrooms that were not possible before.

How can technology help students?

Technology can help a student through the following ways:

1. Online collaboration tools: Technology has helped the students & instructors to share document online, editing of the document in real time and project them on a screen. This gives the students a collaborative platform in which to brainstorm ideas and document their work using text and pictures.

2. Presentation software: This enables the instructor to embed high-resolution photographs, diagrams, videos and sound files to augment the text and verbal lecture content.

3. Tablet: Here, tablets can be linked to computers, projectors, and cloud so that students and instructors can communicate through text, drawings, and diagrams.

4. Course management tools: This allows instructors to organize all the resources students’ needs for the class. the syllabus, assignments, readings, online quizzes.

5. Smartphone: These are a quick and easy way to survey students during class. It is a great instant polling which can quickly access students understanding and help instructors to adjust pace and content

6. Lecture capture tools: The lecture capture tools allow instructors to record lectures directly from their computer without elaborate or additional classroom equipment. The record lectures at their own pace.

Advantages of technology integration in the education sphere?

The teaching strategies based on educational technology can be described as ethical that facilitates the students learning and boost their capacity, productivity, and performance. technology integration inspires positive changes in teaching methods on an international level. The following list of benefit will help in resolving a final conclusion:

1. Technology makes teaching easy: technology has power. It helps in the use of projectors and computer presentations to deliver any type of lesson or instruction and improve the level of comprehension within the class rather than giving theoretical explanations that students cannot understand.

2. It facilitates student progress: technology has made teachers rely on platforms and tools that enable you to keep track of individual achievements.

3. Education technology is good for the environment: if all schools have dedicated to being using digital textbooks, can you imagine the amount of paper and number of trees that will be saved. students can be instructed to take an online test and submit their papers and homework through email. They can be also encouraged to use readers to read …
