One of the biggest challenges to the data storage community is how to effectively store data without taking the exact same data and storing again and again in different locations on the same servers, hard drives, tape libraries etc. There have been many attempts to address these redundancie some more successful than others. There has been an attitude in the data storage cmmuninty that as we saw significant price reductins the cost of many data storage options that data storage savings was an exercise whose time had passed. With the regulatory enviorment becming more stringent, the volume of saved data again begain to explode and more and more options began to be considered to address data storage concerns. The latest answer offered by the data storage field is the technology known as data deduplication. Also known as "single-instance storage" and "intelligent compression"this advanced data storage method takes a piece of data and stores it once. It then refers to this data as often as it is asked by a pointer (or pointers) that replaces the entire string of data. These pointers then refer back to the original string of data. This is especially effective when multiple copies of the same data are being archived. The archiving of only one instance of the data is required. This reduces storage requirements and back-up times substantially. If a department wide e-mail attachment,(2 megaytes in size) is distributed to 50 different email accounts and each one must be archived, then intead of saving the attachment 50 times, it is saved once with a savings of 98 megabytes of storage space for this one attachment. Multiply this over numerous departments and thousands of emails over the course of a year and the savings can be quite substantial. Recovery time objectives (RTO)improve significantly with the use of Data Deduplication reducing the need for back-up tape libraries.This also lowers most storage space requirements realizing significant savings in every area of hardware storage procurement needs. Operating at the block(sometimes byte)level allows for smaller pieces of data to saved, as the unique iterations of each block or bit that has been changed are recognized and saved. Instead of having a whole file saved each time there is a change in a bit of information contained in that file, only the changed information is saved. Hash algorithms such as SHA-1 or MD5 are used to generate unique numbers for blocks of information that has changed.Most effective data deplication is used in conjunction with other methods data reduction delta differencing and conventional compression are two such methods. This combination can greatly reduce any errors non-redundant sytems might incur.
With the rapid advancement in the field of networking and communication, now it is possible to have voice conversation with other people through internet. The device used in voice conversation over internet is called VoIP (Voice over Internet Protocol) which is the routing of voice conversation over IP enabled network.With the demand of wireless network on the rise it is now possible to design a kind of a mobile phone which can be used to communicate between two nodes using the same wireless network.Skype phone is a cellular phone used in the context of wi-fi network, which is used to make free call to other users provided he also uses Skype device.Though the Skype uses Wi-fi network to communicate with other Skype devices, it is not possible to enable this device in any wi-fi enabled spot. These spots must be secured with standards such as WEP or WPA.There are immense benefits one can draw by using the Skype phone devices.The most obvious advantage of using Skype is the cost of the call made. Skype is able to deliver a 100 percent free of charge phone calls to other Skype devices.The only cost, which the user has to tolerate, is the cost of buying the Skype device.Another major advantage of Skype is the mobility. Since it uses wireless wi-fi system, it is possible to take the device anywhere within the radius of the network and continue the conversation with other user. Hence it also acts like a mobile phone with the capability of taking the device anywhere without interrupting the voice conversation.Hence with wi-fi network getting more and more famous these days, the wireless connections are getting spread to more and more areas. With these advances in the field of wireless connection the prospect of Skype is also increasing. Nowadays Skype provide better voice transmission capability through shared wireless network and these days are provided with USB(universal serial bus) charging device so that the phone can recharged by laptops and other PCs.Since this device is based on wifi, like laptops when these devices are switched on they automatically search for any other connection available in the network. These devices have a simple interface having the features like contact list, call history, voicemail, changing your status, adding a contact, searching for a contact, and looking at how much Skype credit you have etc.These devices are definitely much cheaper than using the mobile phones available in the market.Though it may not entirely phase out the mobile phones but it would surely bring in some innovation to the field of communication.Skype, Linksys, and Vonage. Skype phones provide the facility of free call to other user who is also using Skype phone. To make calls to users who are not using Skype phones the call made is generally much cheaper than the call made by land line or cellular phones. The voip technology is used in the outsourcing industry to serve the international clients while sitting in a remote location in other part of the world.
Eric was finally able to buy a digital camera. Though the price of this was very affordable, the delay was caused by other priorities, which also needed to be dealt with.The reason why Eric decided to get a digital camera was to see if it was possible to shoot the same images as those seen in the magazines or in the newspaper. This may just be a hobby and not full time but this person wanted to learn and be just as good as the experts.The first thing that Eric did is being familiar with all of the functions of the digital camera. The individual can make the adjustments or let the machine do it in order to get a clear shot.There are no limits to the number of practice shots that need to be taken. This is because a digital camera has a huge memory, which can hold up to 300 pictures in one session. When the individual is ready to take real shots, the old ones can be deleted.Another technique to be just like the pros is to observe proper lighting when taking a shot. Some pictures will look better when a flash is used while others need to be adjusted to get a night shot. Digital cameras have this feature, which are not available in the old 35mm cameras made many years ago.The individual should also know when to zoom in or out. There are two important factors such as the number of people and the type of background. The focus must be on the subject with the landmark or whatever is behind as the accent for the shot.A lot of photographers both professional and amateur shoot with the model in the middle. Some have noticed better pictures when this is done with the subject on the side, which may work depending on the location.The techniques in shooting just like the pros can be self-taught. There are also books and magazines available but it will be better if someone critiques the pictures by participating in a seminar or in a contest. The objective isnt to win but to improve in the skills already learned by the individual.The person can concentrate on taking great shots especially when there is no need to worry anymore about buying a roll of film or developing.
With the launch of the site rubix website, you can now design a personal site with a few pages or a corporate website bursting with content. And you won't need any special skills, not even a working knowledge of a coding language like HTML.A good design is pivotal to your success. When the visitor lands on your website, arriving via a link on either a search engine or from mention of your website from another source, you have about 3 seconds to catch their attention. Remember, they're only one click away from the browser button. With a quick mouse reflex, they can disappear in a nanosecond. Once they hit the back button, they'll never be seen again. On the other hand, it is just as easy for them to bookmark your website, return to it again, and even recommend it.What is the difference between losing a visitor and winning one over? Content, obviously. Content that holds their interest and that answers some core need. But content, no matter how brilliant, how articulate, how relevant, and how well-formatted is not enough. The frame that holds the content in place -- the design -- can be just as important in securing visitor loyalty.Design does not have to be brilliant to win respect. It has to be highly functional. Here's an analogy:Grocery stores are never works of architectural magnificence, but they are popular. They offer people something they need in a way they can easily find. There is an efficient system of shopping carts, marked aisles, and check out counters. The minute the door swings open, people know how to shop. Rarely are these places ugly, dirty, or disorganized. Those that exhibit chaos soon go out of business. The better stores have an austere, utilitarian beauty. Similarly, a user-friendly website is considered to have a good design. Mind-boggling graphics seldom impress. Like any high quality store, your virtual establishment should be attractive in a utilitarian way, with form built around function. Here are 7 ways to create a winning design.1. Your pages should load fast. Statistics reveal that most people have slow internet connections and that their average patience level ranges from 10 to 15 seconds.2. Your text should be easy to read. When it is too small, it makes the reader squint and start searching for their eyeglasses. When it is too large, they wonder if the website was designed for children learning how to read. Usually, a black text against a white background is best. If you lust for a colored background, it should be a pale shade so that the letters still stand out.3. Your website should be easy to navigate, with each link clearly identified as one because it's blue and underlined. Similarly, graphic navigation elements like buttons and tabs should be easy to recognize and use. While you may personally delight in high-tech special effects, like a mouse movement that leaves a trail of stars, these should be avoided. Keep navigation plain, simple, and easy-to-understand. If navigation is not intuitive, a visitor will simply navigate away from your website.4. Your layout from one page to another should have a consistent theme. If the headers and navigational clues shift dramatically from one page to another, people may very well believe that they've drifted to another website. Use a stylistic theme to weave a sense of continuity from one page to another.5. Avoid music! Frankly, most websites that greet the visitor with a loud burst of music instantly frighten them away. It does not matter how beautiful the music. You could be playing something as soothing as Mozart's Eine Kleine Nachtmusik Allegro and still offend the visitor. The reason people use music is because it does work offline.When you push open the door of a physical store and are greeted with pleasant music, it uplifts you, the customer, puts you in a better mood, and encourages you to linger and shop more. But on a website, the visitors only response is to escape as fast as is technologically possible.6. Make your design compatible with the most popular browsers. What may look great on Mozilla Firefox may look strange on Internet Explorer. If possible, view your website from Internet Explorer, Mozilla Firefox, Opera, and Safari. 7. Design your website for all screen resolutions. While most people use 1240 x 1080, some still use 800 x 600, even 640 x 768! What looks perfect with high resolution may be unrecognizable when viewing in 800 x 600.Good design, then, is subtle. It should be quietly running in the background allowing your visitor to focus on your content. Your purpose is to entice visitors with your products and services. In other words, content becomes foreground only when design elements become background. Since it is content that sells, a "loud" design will not improve your business. Flashy presentations may attract attention offline, but online subtle effects sell.While this type of thoughtful design can take hours using traditional HTML editors, it can be done in minutes with Site Rubix Website.For more information: site-rubix-check.blogspot.com
Before you select a registry cleaner for your windows based PC, find out how beneficial it is for your systems performance.These days, more and more computer users are using "registry cleaner" software to keep the registry clean and to keep their computers in good health. Computers are the information highway of the 21st century, and most households in the United States use computers for various reasons. The more you use your computer, more information gets stored in its registry. The benefit of a registry cleaner is that it helps slim down the registry by removing the unnecessary data thereby making your computer run faster. The registry of your computer is the section where all applications create entries for temporary data, and these entries are never deleted by on their own. The more data your computer processes, the more bloated your registry gets, often slowing down your computer.It is necessary that you use a window registry cleaner, periodically, to remove all the unnecessary data in the registry. Over time the invalid entries, resulting from uninstalling or incorrectly removing of the software accumulate in the registry. A registry cleaner simply deletes these entries from the registry and helps your system to function at its optimum level.The Benefits of Cleaning The RegistryThis is normally what most computer users do: Frequently install or uninstall programs Delete software that was never really fully "uninstalled"Alternately, your computer may have an embedded Spyware, or you may have unused but undeleted drivers in your system. All such accumulated problems can lead to stalls in the system, or reduced operating speeds. This is where a registry cleaner comes in handy. Before the problems rise to such levels, cleaning your registry periodically gets rid of all these extra entries; trimming your registry down and making your computer run at a faster speed.With improvements in technology, newer window registry cleaners are coming in the market with new improved features: A registry cleaner with a scan and repair feature scans the entire registry records, and does not eliminate valid records. It leaves your computer with a trimmed registry and a better computer performance. There is a feature that is similar to de-fragmentation of the files. It removes the empty spaces and fragments, making the computer run faster. Certain registry cleaners come with special features that detect and clean the embedded keys that are generally undetectable. These embedded keys have malicious codes that are used by malware (malicious software). Most registry cleaning software have a schedule and forget feature, which allows you to set a schedule for a registry scan, fix, backup, and eliminate the routine unnecessary entries in the registry.When you first install a new system, you will most probably, never notice a registry problem. As your usage increases, the frivolous entries in your registry become larger and larger, especially with the installation and removal of software, drivers, and other components. This slows down your complete system.This is where you benefit the most from using a window registry cleaner that deletes these unnecessary entries and increases the operating speed of your system.
