Many studies have been done on the risk parents consider to be on the internet and what safety procedure have been taken for kids safe surfing for online. Apart from few countries like Netherlands, Sweden and Denmark, when comparing to rules on TV-watching it seems parents are more likely to set rules for what kids are allowed to watch and do. We seem to know the limits that are for TV materials more often than we think of online limits.
Maybe I is due to we have been told about this in some campaigns much more often than we have heard campaigns about safe surfing. People seem to know the rating system for movies, e.g. the green for allowed the yellow for not for under 12 years and red for under 16. USA and Europe have different system both movies but people seem to be more in touch with it than they are in touch with general concern on the internet.
Saying that could give us a false knowledge of we are setting rules, but even though in most countries we are more likely to be setting rules for the TV than the computer surfing most parents are not setting rules enough rules for TV or the internet. We could say with TV-watching most rules are being prepared for us and therefore it is much simpler place to set rules for, because the TV-network will air banned movies later at night and will tell us if it is gore, sex and violence. But when it comes to sites there are millions of sites and they are available up all hours of the day.
Therefore it is of course much more important to set rules and monitor the risks online and we cannot trust the site owners of the world to set the limits for us. It seem a little scary we not just have fewer rules on the internet than the TV because what we are facing is a lots more dangerous playground than our tv set.
Most parents today grew up with TV and know what it is about and many of those same parents are just learning to surf online themselves, because they did not grew up with the internet, as it is so new. So parents are less concern because it is a new playground for them, it is positive technology and we are just starting to wake up to the negative and harmful part of the internet.
The risk is online and we need to know of them with hateful website, violent and pornographic material and not to mentioned growing concern of pedophiles online preying on children. When will we wake up and see it is a harmful place to have rules and safety procedures online to protect our kids form online threats? Hopefully we are today!

INTERNET HISTORY: Beyond ARPANET
The Internet’s beginnings took place in a United States Department of Defense program for a strategic computer network. It was designed to carry sensitive and critical data over a computer network that was supposed to be able to remain intact in the event of nuclear attack. The project was called ARPANET, for “Advanced Research Projects Agency Network. The ARPANET was based on a packet-switching network. Any given unit of data could be divided into packets, and these packets could be sent computer to computer, to be reassembled by the receiver. Along the way, these packets of data were routed through various computers along the network, requiring that each computer be able to communicate with all the others. The network was designed to provide simultaneous links among all the computers on the network.
Depending on whether a given computer site on the ARPANET was busy – or perhaps taken out by a bomb – the same route might not be available for all the data packets. This was okay, because it was not necessary for all of the packets to take the same route. As long as the packets carried the information to the destination computer where it could be reassembled, any computer on the network was as good as the next. ARPANET also created certain basic network communications and control protocols known as Transmission Control Protocol/ Internet Protocol, or the ever famous TCP/IP. It simply refers to the set of rules by which computers linked to the Internet use to operate and handle the data received over a network.
The ARPANET became ever more popular and interconnected, and its user base grew by leaps and bounds. Eventually, commercial computer sites began hooking into the network as well as educational, scientific and governmental sites that had more tradition on the network. As the network grew, the military moved its portion of ARPANET to another entity, and thus the Internet was left to take shape.
In 1989, researchers at the European Organization for Nuclear Research (CERN) created a worldwide network of supercomputers to smooth the progress of access to data for doctors, physicists, and other scientists and technocrats. The CERN network quickly grew into the massive Internet area called the World Wide Web. The web is what most people today call the Internet, although there is in fact much more to it. With page-oriented documents and links to graphics, sounds, and videos, today the Internet is truly a multimedia experience.

A lot of online business owners start with no money
A lot of online business owners start with no money. They have to do everything themselves -- the preparation of a product, the development of a marketing strategy, the actual building of a website to cater to their product's marketing needs. As their business expands over time, they will find that their simple "homemade" site might not be enough to cover everything, and they will have to take a day or two away to simply dedicate that to the website expansion.
Sounds familiar? Chances are, you're someone who started everything with no money too, so you're pretty skeptical when it comes to giving away your money in exchange for something that you could have done yourself. However, there is a lot more to hiring a designer than just finishing up a job that you don't want to do.
When you hire a web designer to do your job for you, you are doing more than just handing over the "dirty job" to someone else. In fact, by paying a little money, you can let the designer worry about the little annoyances that always evade the main picture and only come haunting when you're halfway through the job. That way, you will be more focused and have more time to spend on your actual business strategy.
On the other hand, the designers you hire a professionals so they are good at what they do. By outsourcing your web design jobs to them, you won't have to worry when problems surface because you can always get them to fix it for you. Again, they will be able to pin point the problem and fix it faster than you probably will be able to.
Also, the work you pay for will turn out more professional than what you can achieve because the designers have been doing it longer than you have. After all, they do it for a living so they have to be good!
So, remember to not just work your business, but grow your business too!

Anonymous Surfing Techniques: How to Use Anonymous Proxies Online
Today, the Internet is an integral part of many people's lives. Whether it is to pass time, to entertain themselves or to communicate with others, the Internet is important to many people worldwide.
Along with its widespread use, the Internet has also brought along with it a very frightening development. You may be under the scrutiny of someone monitoring your online activities. Government agencies, advertising networks and search engines monitor online activities of whomever they want to keep tabs on.
Although it's said to be for security reasons, many think it is an invasion of their privacy. You should however, become aware that what you do on the Internet should remain private and it should remain confidential, even if you do any thing illegal. Expecting your Internet experience to be private is your right.
The technology available to monitor you is so effective that everything about you can be pinpointed to the greatest detail including your geographical location. Web Masters, Government Agencies and Search Engines can watch your every move and also record your IP address.
These trackers may examine the sites you visit and record your search history at search engines like Google, Yahoo and others. It's easy to find your exact physical location worldwide using an IP address.
Why do people track you? For advertisers and businesses, they do this to improve their marketing effort and to pre-empt competitors from gaining an edge with you, be it for product or company loyalty. Some government agencies around the world profile Internet surfing behaviors. Such tracking enables them to exercise some level of, online censorship.
If you want to stop such tracking, there is one thing that you can do that is sure to fox them. Surfing the Internet anonymously is the answer. Today, there are software programs available that can help conceal your true IP address by randomly masking it to conceal your identity.
Using such proxy servers, anonymous surfing of the Internet is possible. No one will be able to track you on the Internet and you can protect your privacy. By randomizing your IP address, the proxy server simply enables you to surf anonymously. Each IP Address is unique which means it can be traced to you individually. When it is randomized using proxy servers, you are sure to keep your web surfing activities totally private.
There are a number of software programs available that can set up your proxy server and enable you to surf the Internet anonymously. You can thus ensure your privacy by installing one such software in your computer. You need never worry about others trying to track what you do and to use devious methods to influence you.

A Basic Primer to Programming Flash Games
I have written this article as a basic primer to flash game programming. In this article I will cover how basic programming can be applied to creating flash games. This article will not cover graphic design or drawing. If you are already proficient in another programming language this article will certainly help in the transition to flash game programming.
This article is aimed at people will very basic programming knowledge. An interest in flash games is certainly a bonus when learning to program them. Programming languages of any king will help you to understand this article and its terminology relating to flash game programming. I will be using very general programming terminology.
The very first thing I am going to cover is variables. A variable is a place where either a number, string(text) or a Boolean(true or false) can be stored. Variables can be changed at run time this means during game play. For example number of ammo in a weapon can be stored as a variable. As the user shoots the weapon the variable is degreased. A very symbol way in programming syntax would be: On press decrease the ammo variable by one.
The next thing I’m going to discuss is hit tests. A hit test is performed to detect when two symbols make contact. When these symbols make contact a true value is returned while the objects are not in contact a false value is returned. As you can imagine this very simple function has many uses where game programming is covered. An example of this could be when bullet hits its target play an animation of the enemy’s death and remove them from the screen. So the basic in programming terms to this would be: if bullet and enemy’s hit test is equal to ‘true’ then activate function enemy death that takes the value of the enemy’s unique identifier. Inside the function would be syntax to display the animation and remove the symbol from the screen.
Displaying a life car can be achieved by first creating a small rectangle graphic. Next make the rectangle a movie clip and sets its identifier to a name of your choice. After this create a variable and set the variables values to ‘100’ and strict data style it to a number. Once you have done this, open action script and set the rectangles .length property to the variable you just created and set to ‘100’. This way when the variable is increased or decreased the bar will change lengths. So when the variable is high the bar is longer and when the variable is low the bar will become shorter. Remember variables can be changed at run time there for so can the bar. Using a simple hit test to increase and decrease the variable which in turn changes the bars length. Producing a working bar that shows how much value the variable contains. This can easily be added into a game where the length of the bar resents the amount of life a player has remaining.
I hope this article showed you just how simple the elements that make up a flash game can be. Games may look daunting but once you break down there elements they become a lot simpler than they may first appear. If you have no yet tried making a game using flash then I strongly suggest you give it ago. The best way to learn flash is by experimenting and creating working scripts.

All About Computer Programming
Computer programming is at the core of any computer operation. Unlike usual electro mechanical devices, a computer requires software to carry out instructions. At the lowest level, machine code is used to control the hardware and operations of a computer. The machine language is a set of zeros and ones and rather tedious to handle. Therefore the instructions are coded in a higher level language called a computer program. The conversion of a higher level language into a machine code is carried out by assembly level languages or assemblers. The transformation is completed without any human interface.
During the initial days when computer programs were still at a nascent stage of development, languages such as COBOL and BASIC were highly popular. As the computing power of computers increased ,the demand for more efficient programs emerged. The third generation programs had better portability and efficiency compared to the earlier generations. The need to handle enormous amount of data gave rise to specialized software called database management software or more specifically relational database management software. Companies like Oracle, IBM and Microsoft have developed their own version of RDBMS. On the processing front ,Mainframes were using COLOL for business applications and FORTRAN ( Formula Translation ) for scientific applications.
The concept of modularity became popular when hundreds of software programmers worked simultaneously on a single large project. Object oriented programs like C++ gathered popularity. The code used in these higher level languages was reusable and the techniques could provide for better efficiency.
Microsoft meanwhile brought out its own operating system which could be used on personal computers. In a matter of years the Windows OS became a unprecedented success. The OS2 operating system used by Apple computers was relegated to a second position. IBM has been providing other system software but none could reach the popularity levels of Windows. The only problem with Windows is the issue of security breaches. Though Microsoft has been striving hard to plug the security holes, it has not been entirely successful.
Modern computer programs strive more and more to behave like human language. Technologists believe that a day would come when one could program a computer by given verbal instructions. Surely that's not going to happen in a hurry. Artificial intelligence, expert systems, fuzzy logic and many more state of the art technologies are changing the face of programming.
Computers unlike any other machine require a software program to operate. It speaks in machine language which is gibberish to the human mind. Higher level languages are used to translate recognizable instructions into machine language. As we progress, the higher level languages would resemble human languages.
At the beginning of the computer era, a single program used to execute different functions. Today, specialized programs are tailor made for different applications. Complex programs require many programmers to work simultaneously on a single project. Modular languages are well suited for such large projects. Object oriented programming has become popular due to their modularity and ease of use.

Permanence of Paper
Historically, most of society’s writings and visual images have been recorded on paper. However, paper is an organic material and is subject to deterioration caused by chemical, physical and biological agents. While documents on paper several hundreds of years old have endured, most paper manufactured in the last two hundred years has a limited storage life due primarily to acidity induced as part of paper manufacturing processes used during that time period. Exposure to acidic air pollutants also contributes to paper degradation.
Chemically this degradation is a result of acid hydrolysis of the cellulose polymers which are themselves responsible for the intrinsic strength found in paper sheets. The hydrolysis reaction are also autocatalytic since they produce additional acid products which themselves further increase paper acidity and accelerate degradation occurring.
Since untreated paper is too absorbent for the application of inks, hydrophobic fillers also called sizings are added to paper surfaces as part of the manufacturing process which can also have an impact on paper permanence. Sizing impacts absorption of liquids to prevent feathering of inks and dyes and to provide a crisp image.
Paper made before the 19th century was often made by hand from linen and cotton rag materials which are excellent sources of high cellulose, long fibers. Gelatin, from animal hides, was used to size such papers and because the resulting papers were neutral to only slightly alkaline they had very good storage properties. The paper machine appeared at the end of the 18th century, and as the demand for paper outpaced sources of available gelatin, cotton rags and linen, wood fiber took the place of cotton and linen. However, wood has shorter fibers and lower cellulose content along with lignin so that chemical methods had to be developed to free fibers from wood and other plant matter to supply the increasing amounts of paper furnish needed. Mechanical action [“beating”] to soften and bleaching to whiten these new materials yielded pulps that could be laid down by machine as a sheet with subsequent drying to form paper.
Gelatin was replaced in the early 1800s with rosin which was mainly abietic acid isolated from pine resin. Alum (papermaker’s alum or aluminum sulfate) was used to precipitate the rosin onto paper forming an alum/rosin sizing. Aluminum sulfate reacts with water - and produces sulfuric acid – and production of paper on the paper machine demanded additional alum, so papermakers often used the salt in excess. The industrial revolution added outside factors such as air pollution and acidic oxides of nitrogen or sulfur and ozone to the environment. Early bleaching processes using chlorine and hypochlorites, strong oxidizers, also degraded the cellulose and reduced its strength. All of these led to diminution of paper properties. Fortunately, bleaching processes have totally significantly over the past few decades and the chlorination and hypochlorite steps are no longer used resulting in less damage is done to resulting fiber.
The strength of paper results from a combination of factors. The most important is the condition of cellulose, in particular chain length. Cellulose is made up of repeating units of glucose monomers and the number of glucose units present provides a measure of degree of polymerization (DP). In native cellulose from wood DP is about 10,000. Depending on the nature of the pulping and bleaching, the DP of processed cellulose falls to a range of 600 – 1100.
After this reduction the paper fibers are still quite strong, but fiber strength is highly dependent upon retaining this DP and acids break cellulose bonds randomly often cutting the cellulose polymer in central regions. These attacks drastically reduce the DP of cellulose and quickly weaken the fibers. Alkalis also attack cellulose, but by a different mechanism, in which only end units are removed (end peeling) so that alkaline degradation has much less effect on reducing DP (Bristow and Kolseth, 1986)

Web Design and Multimedia
MULTIMEDIA FORMATS
Multimedia elements in web design (like sounds or videos) are stored in media files. The most common way to discover the media type is to look at the file extension. Picture formats are recognized by extension like .gif, .jpg as well as others.
Sound Formats: - Sound can be stored in many different formats
1. The MIDI Format: -- The MIDI (Musical Instrument Digital Interface) is a format for sending music information between electronic music devices like synthesizers and PC sound cards.
Sounds stored in the MIDI format have the extension .mid, .midi
2. The AIFF Format: - The AIFF (Audio Interchange File Format) was developed by Apple. Sounds stored in the AIFF format have the extension .aif or .aiff extension

Why is My Computer Internet Slow? Steps to Speeding up Your Surfing
Usually slow computer problems and slow internet problems go hand in hand. A variety of factors can impact both issues and there is no one fix that can make the issue go away. The good news is that the problems can be resolved rather quickly if certain steps are taken.
Obviously, if you have dial-up service or free services where the servers are weighed down, you are more likely to experience computer internet slow downs. These problems can sometimes go away by simply upgrading the services you have.
If you choose to keep the costs lower than what the high speed investment is, you will likely have a tough time getting your internet much faster. Still, some of the steps below may help.
Step One: Download and Run a Top Registry Repair and Cleaner Software. This will rid of Internet Explorer plug ins that are not vital and will create a better efficiency in the Windows registry (file structure for the operating system) which will speed up your computer.
You can do a free download and scan initially to ensure that registry errors are found before investing in the repair option. Ensure that the product has both repair and optimization features.
Step Two: Download and Run a Quality Spyware Program to Remove any Spyware, Adware, Malware, and Viruses. This can include Trojans, hijackers, keyloggers, and pop-up generators.
Unfortunately, there are destructive people who stay awake at night thinking of ways to harm others. Unauthorized downloads on your computer is one way they achieve their goal.
Step Three: Do a Broadband and Wireless Modem Reset (30 seconds will do great).
Step Four: Clean the History and Temporary Files off Your Browser (Settings, Internet Options).
Step Five: Use Free System Resources to Make Room on Hard Drive. (Start, Accessories, System Tools, then run Disk Cleanup, Disk Defrag, and create a restore point on system without running the actual full restore feature.
Step Six: Remove Any Unneeded Programs off Your Computer. (Start, Control Panel, Add or Remove programs, then choose programs to remove that you do not plan on using soon).
Other Tips to Increase Internet Speeds:
Check connections. Make sure that each of your connections is up to par and that phone lines are not corrupt.
Check with your broadband provider about testing connection speeds. Do several tests and average out.
Try to avoid high traffic times when many people are on the same servers at the same time.
Upgrade your speed through provider. There are many services available (in most areas) and you are not stuck with your current speeds.
If all else fails, do a full system restore back to factory condition and reinstall vital programs that you use. This is time consuming but definitely an option if all else fails.
Set up a firewall to be in control of what programs have access to the net and vice versa.
If your computer equipment (hardware) is outdated, it may be time to upgrade since prices are great on computers these days.
After completing the actions in this article, computer internet slow downs will be a thing of the past.
Be sure to restart your PC for any changes to apply.
