What Are Proxy Servers?

good ideasAll websites visible on net are hosted on computers which are called proxy servers and since they serve as a connecting link between client and other servers, they are like middlemen.

Proxy Server is an important component of network as it is works as an intermediate communicating agent. When someone visits a website or service on an external network or an internal or local one, then it is the computer or its terminal that establishes direct communication with the respective server or service related to that particular web page being accessed.

The advantage of having a proxy server is that the computer of the individual doesn’t directly establish communication with the server while accessing the internet; instead, it is via another computer. Thus the proxy server functions as the actual communication on behalf of an individual. It presents to the host the requirement of the individual and finally directs the required information from the host to the individual.

Many people hesitate to use the proxy server as the process seems to be slower. But using such a server is highly beneficial although the concept has acquired a bad image due to its facilitating illegal activities. At first proxy servers were so designed so as to hide the identity of the computers belonging to an internal network.

There has been a steady increase in the number of people who use such servers. Such servers protect the computer from snoopy neighbors and also help to speed up certain computer operations by means of using a “cache.” Caching is important as it helps in filtering and scanning data both outgoing and incoming thus aiding in spotting possible virus attacks. Use of proxy servers has ensured that more individual can access the internet safely.

In schools and work places proxy servers have become inevitable. It helps in prohibiting  individuals from accessing questionable and forbidden websites, watching impermissible videos, engaging in unproductive work while at work like going to social networking sites, connecting  with friends through chat, playing online games and many others. Hence using proxy servers in the professional areas has proved to be extremely beneficial.

Another reason as to why people choose to use proxy servers is to remain anonymous on the Internet. In this way they can protect their identity by masking the Internet Protocol or IP addresses of their computers. One can also communicate through numerous proxies or identities if the scope of work so demands.

If you haven’t yet used a proxy server then it is high time you consider using one because you will be able to hide your IP, which is an unchangeable and unique piece of information that can be used by cyber criminals for the purpose of accessing your data.

A billboard is one of the oldest forms of advertising and credit for having discovered it goes to our ancient cave dwelling ancestors who used their rudimentary tools to adorn the walls of their caves. Since then the advertisement industry has advanced by leaps and bounds but billboards have still retained their aura which is why billboard lease is a lucrative business even today.

In order to start earning from billboard leases, either the individual should be the owner of a billboard or go about it from the commercial point of view. If you own a billboard and wish to make money out of it, the foremost step which you must take is to maintain the billboard so that it appears nice, clean and brightly lit. Once the board as well as its neighboring area appears to be in optimum shape, it is time to advertise the space by mentioning the contact information as also the price.

Another aspect of billboard leasing is taking a professional approach and creating a good impression at the first opportunity. These factors are important to get a good deal from companies which have recently jumped into the fray and hence will always opt for billboard advertising. Thus targeting such companies will be advantageous for those who wish to take up billboard leasing as a source of income.

Discounts are an important part of business and deciding on the schemes and their durations depends solely on the owner. A noteworthy recommendation in this regard would be to offer higher discounts for longer lease periods or offering a discount at an upfront payment so that customers feel not only justified in doing so but are convinced about the worth of the deal as well.

Billboard leases are a good option for those who aren’t particularly interested in real estate options. In order to engage in this enterprise you should submit all the necessary details and acquire a license. This is a very simple task because the initial investment is not that high and there are hardly any tests.

Some of the other requisites would be to find various sites around the area and applying for permits for putting up billboards on them. Transportation is a must along with various types of equipment like maps, measuring devices, sign ordinance and so on. After everything has fallen into place it is just a matter of time before billboard leases start fetching an income which is many times more than the original investment.

In addition to billboards you can also check out cell tower leasing. Learn more about this type business by talking to a cell tower leasing expert.

GPU computing refers to the combination of CPU and graphics processing unit (GPU) in performing computations of scientific and engineering related fields. The major advantage of GPU is that each component supplements the other to speedily perform the task. While the sequential aspect is looked after by CPU it is the GPU which is entrusted with the burden of solving mathematical riddles.

It is the community of scientists and researchers who started using GPU for computing at the turn of the century. They discovered the usefulness and capability of GPU for computation as a means of performing a wide range of scientific applications.

The only obstacle to its utilization was its lack of compatibility with graphic programming language. To overcome this handicap scientist modified GPU and added high level computer language support.

These days most of the computers come with GPU which makes it easy to design the graphics used in animation movies as well as computer games. Also, the GPU perform most of the graphics output functions.

There is one slight factor that needs to be kept in mind and that is sometimes the current driver may be compatible but a lot of times it requires the latest models and versions of drivers for running GPU.

For a successful use of the GPU program ensure your computer has an inherent capability to run it depending on the operating system installed. Each operating system has its own version of GPU program. The type of the adaptor and memory size in your computer also counts. Take care of any special requirements that may arise as a result of the project you intend carry out.

The hybrid nature of this technology enables it to run numerous parallel threads thanks to the hundreds of parallel cores featured in it. Unlike the CPUs that specialize in serial operations, the data entered into the GPU is split into several fragments and each of these fragments are processed in parallel. Therefore this reveals the secret as to why the speed is so high.

It is this parallel processing architecture which is being capitalized upon by programmers for performing the most critical sections of their task accurately and quickly. Further research into this field has proved that if the CPU is offloaded systematically and gradually, the increase in speed is phenomenal and likely to improve even more with new technologies on the horizon.

To avoid unsteady graphic output and the need change preferences, it is better to perform GPU computing with your computer switched off. Have it configured to automatically switch off when incompatible operations are run. These are important aspects of GPU computing that should be observed to ensure an optimal performance of the applications.

Compared to the amount of work which it can handle, a GPU is an economical application and a further advancement is a multi GPU system. As long as its basic requisites namely the parallel code and appropriate language conversion are provided, the GPU will continue to amaze the world with its astounding results.

A popular browser that has convenience of hassle free installation and easy usage is the Microsoft’s Internet Explorer. In spite of its ability to get installed side by side with the installation of Windows operating system, many people prefer to install and use Mozilla Firefox even though it entails putting in extra time and effort. Therefore, this happens to be another well known option for surfing the net.

Firefox symbolizes the browser of choice for the group of people who do not like using Internet Explorer or they prefer more functionality and flexibility in their web browser. One of the best aspects of Firefox is that you can use add-ons which are also called ‘plug-ins’ – these are small programs that can help enhance the functionality of your web browser. Ever since its introduction in 2007, there has been over two billion downloads just for add-ons.

There are many advantages of using these add-ons. With their help, one can utilize a great deal of services in a single domain which is the web browser. Another reason for the great demand and popularity for the add-ons is that with the use of the add-ons there is no requirement to download and install separate programs on the computer thus enabling the user to economize on space.  RAID Storage may be one option for space storage.

A small program named ‘Stylish’ is a great boon for those people who do not like badly designed and unsightly plain looking websites. One can download it from the Firefox browser and with the help of this add-on, one can use his or her own creativity to design appealing and attractive websites.

A free of cost add-on is “WOT” or “Web of Trust”. Once this add-on is installed, it helps an individual to identify safe websites thus protecting the computer from viruses and malwares. After installation one will be able to see a small icon which will help to identify the safe and harmful sites with the help of colors like green denoting safe site, yellow for unknown and red for unsafe sites.

While surfing it is common to be interjected time and again with ad windows popping up on their own. To tackle this situation there is an add-on named Adblock. This add-on is useful as it helps to block out the ads that keep popping up. This add-on further helps one to make his or her own configurations and block out the ads that one does not want to see.

Firefox has the feature of Fire FTP that helps one to save time while downloading and uploading information from a particular website. It is a free FTP client and operates in less time than other FTP clients thus saving time, frustration and money.

Everyone must have surely experienced this at some point that at times it is just not possible to read through all the web pages due to lack of time. In such a case, what are your options? You can use an add-on known as ‘Read It Later’ – this helps you to save web pages quickly and easily for future reading and it also allows you to check off each web page that you might have finished reading.

When the GPU, an acronym for graphics processing unit, is used in combination with the CPU for the purpose of performing computations related to the scientific and engineering fields, this application is referred to as GPU computing.

Its advantage to the user lies in its exceptionally high speed wherein the sequential aspect is looked after by the CPU and the calculations are executed by the GPU.

It is the community of scientists and researchers who started using GPU for computing at the turn of the century. They discovered the usefulness and capability of GPU for computation as a means of performing a wide range of scientific applications. The only obstacle to its utilization was its lack of compatibility with graphic programming language. To overcome this handicap scientist modified GPU and added high level computer language support.

Today most of the computers are equipped with GPU which accounts not only for most of their graphics related output but also for the graphics used in computer games and animation movies. One of the considerations however is the driver and while the current drive may be suitable, there are times when the later versions and models of drivers may be required for running this application.

For a successful use of the GPU program ensure your computer has an inherent capability to run it depending on the operating system installed. Each operating system has its own version of GPU program. The type of the adaptor and memory size in your computer also counts. Take care of any special requirements that may arise as a result of the project you intend carry out.

Owing to the hybrid nature of GPU technology, this kind of computing application features hundreds of parallel cores and thus is capable of running as many parallel threads. As compared to CPUs’ which are specialized in serial operations, data fed into the GPU is split into many fragments each of which is processed in parallel thus explaining the high speed.

With this high speed and accurate performance many programmers turn to GPU to execute their task. The speed can be enhanced even further if the CPU is methodically and regularly offloaded. With emergence of new technologies in addition to parallel processing GPU computing is bound to improve even further.

An important aspect which the user should be aware of is that GPU computing is performed only when the computer is switched off. Not heeding this advice would result in unsteady graphic output and moreover would also require a change in preferences. It can also be configured to switch off automatically when incompatible operations are being run.

Considering the amount of work that it can perform, the GPU is an economical application. If you want an even more advanced option then you can consider using a multi GPU system. The GPU along with the right language conversion and primary requirements like the parallel code is indeed an impressive and powerful team.

All visible websites on the net are hosted on computers which are called servers. However there are some people who would like to protect and preserve their privacy and so use proxy servers which function between the client and the other servers and hence are known as intermediaries.

Proxy Server is an important component of network as it is works as an intermediate communicating agent. When someone visits a website or service on an external network or an internal or local one, then it is the computer or its terminal that establishes direct communication with the respective server or service related to that particular web page being accessed.

The advantage of having a proxy server is that the computer of the individual doesn’t directly establish communication with the server while accessing the internet; instead, it is via another computer. Thus the proxy server functions as the actual communication on behalf of an individual. It presents to the host the requirement of the individual and finally directs the required information from the host to the individual.

Earlier proxy servers were used to hide the identity of computers operating on and internal network. From its method of operation, accessing the web world via a server which acts as proxy appears to be slow and also such servers make it easy to perform offensive practices and illegal activities. Hence its use was avoided till the point in time was reached when it was proved as being absolutely advantageous.

Not only does it protect the computer from prying eyes but also helps to increase the speed of certain web resources and network by means of caching. Caching is imperative because it serves as a content filter and scans inbound as well as outbound data for potential leaks and viruses. Over the past few years there has been a tremendous increase in the number of people using proxy servers because people are becoming more and more net-savvy.

By using proxy servers in schools and at workplaces, the concept of content filtration would prevail which is quite useful for keeping the students and employees from going to ‘questionable websites’ and viewing forbidden videos or from engaging in ‘non-productive’ activities like connecting with their friends on social networking sites or from playing online games. Thus it is understandable as to why people would want to use proxy servers for professional settings.

Proxy servers are also advantageous as they help people to remain anonymous on the Internet. This helps one to protect his or her identity by masking the Internet Protocol or IP of the computer. In case one’s work is such, and there is the need for it, it is possible to use different proxies or identities for communication purposes.

In case one has not yet utilized a proxy server, then it is time to do so. This would help to hide one’s IP which is a permanent and unique identification mark that cyber criminals can utilize to access one’s personal data.

Development of HTML 5 began in 2004 and now, 6 years later, it’s still nowhere near being finished.  Co-editor of HTML 5, Ian Hickson has said that we may need to wait until 2022 for the final draft.  Even so, HTML 5 has a lot of offer.

Here are some of the highlights:

Videos – HTML 5 allows you to embed videos on a web page as easily as you can now add photos. And what’s even better is you can also manipulate a video with built in video controls

Canvas – a new dynamic graphics generator will also be included that basically offers users a drawable region within HTML code. You will be able to create graphics and even complicated animations, all without having to use an external plug-in.

Geo-Location – Javascript allows you to share your geo-location with trusted web sites. Your geo-location will be determined by such sources as GPS, Wifi, Bluetooth, your IP address, and more.  And don’t worry, if you don’t want to share your geo-position, you don’t have to enable it.

Application Caches – this will allow you store and access web applications all without needing to connect with the net.  Google gears uses HTML 5 codes for its Applications Cache.

At the moment, some of these functions have some compatibility issues with IE, but keep in mind that HTML 5 is still in development so compatibility and even certain features are likely to change and improve. If you have to work outside, check out the sunlight readable LCD monitors.

Certainly, there is a lot more ahead with HTML 5 but right now, these exciting new features will certainly help developers, designers, and even the general population.

Cool Software Via Exergames

Have you heard about “Exergames” or games and devices that were designed to be played using physical motion. These games are the natural evolution to the motion sensitive games that popular consoles such as the Nintendo Wii are known for.

While the Wii incorporates player movements to control a game, such movements could be restricted to flicks of the wrist – not really the idea of a sweat breaking routine. The sensors in the Wii could not distinguish between flicks of the wrist and aerobic movements that are necessary to induce physical exertion.

The University of Teeside, headed by Project Leader Dr. Iain Spears are spearheading efforts to build a device that forces players to exert themselves physically. Unlike the video motion capture devices for popular consoles, the device can detect motions that exceed the 30 frames per second input limitation.

The project utilizes LED clusters and inertial measurement units.

Dr. Spears notes that “It’s a way of getting people to do the activity associated with boxing in a safe environment where they are not getting hit on the head,” said Dr Spears.
