Facebook

Facebook today opened a new data center in Luleå, Sweden, making it the company's first in Europe and the first to use only servers designed by Facebook itself.
The milestone is a result of Facebook's two-year-old Open Compute Project, in which the company created its own specifications for servers and shared them with the world for anyone to use. Instead of buying servers directly from the likes of HP and Dell, Facebook creates more efficient designs that strip out extraneous hardware and software and then pays original design manufacturers to build them. As we reported in February, the data center in Sweden was set to become Facebook's first containing only Open Compute servers.
"As our systems come online for the first time, we are proud to say that this is likely to be one of the most efficient and sustainable data centers in the world,"Facebook wrote in its announcement, stating that the data center is now handling live traffic from users around the world. "All the equipment inside is powered by locally generated hydro-electric energy. Not only is it 100 percent renewable, but the supply is also so reliable that we have been able to reduce the number of backup generators required at the site by more than 70 percent. In addition to harnessing the power of water, we are using the chilly Nordic air to cool the thousands of servers that store your photos, videos, comments, and Likes. Any excess heat that is produced is used to keep our office warm."
"Nearly all the technology in the facility, from the servers to the power distribution systems, is based on Open Compute Project designs," Facebook continued. "This Facebook-founded initiative encourages the development of 'vanity-free' hardware designs that are highly efficient and leave out unnecessary bits of metal and plastic."
The data center has an impressive PUE rating (power usage effectiveness) of 1.07. This means the building consumes 1.07 watts of power for each watt needed by computing equipment. Facebook has been posting near-real-time PUE data for its US data centers and plans to do the same for the Sweden one.
In addition to server designs, the Open Compute Project has created and released designs for server racks, storage systems, motherboards, and interconnects. Last month, Facebook announced that its next goal is to release a design for a top-of-rack switch that can run any type of networking software. This could help give businesses alternatives to Cisco and the other leading network vendors.

Codemasters

Codemasters


          Codemasters Software Company Limited, or Codemasters (earlier known as Code Masters) is a British video game developer and publisher founded by David Darling and his brother Richard in 1986. Codemasters is one of the oldest surviving British game studios, and in 2005 was named the top independent games developer by Develop magazine. But now Codemasters change their name to "Codemasters Racing" because they don't want to try a lot of money to made RPG, FPS games, and don't complete. They say "We will stop made RPG or FPS game, Codemasters will go ahead to the racing games"

     Codemasters founded in 1986 by Richard and David Darling (who worked previously for Mastertronic), Codemasters established themselves in the growingZX Spectrum market, mostly with action games that required the player to solve simple puzzles by combining different objects, such as the Dizzy series. While rooted in the ZX Spectrum, Codemasters did not write exclusively for this computer - they also released software (including the Dizzy series) for the Commodore 64,Commodore 16BBC MicroAcorn ElectronAmstrad CPCAtari 8-bitCommodore Amiga and Atari ST.
They were famous for releasing a long series of "Simulator" games, mostly sports simulations (such as Pro Boxing Simulator). This led to the parody "Advanced Lawnmower Simulator" being developed, praised to the skies and then published byYour Sinclair magazine as an April Fool's Day stunt.

Network on music instrument.

Network on music instrument. If you think the network is only on PC, I will telling you "You are false" The network not only on the PC, It can be on telephone, smartphone and it can be on the music instrument. Mostly it on the Live Stage Concert, when you see the concert you can see the Mixing control on down of the stage. That like a Modem of network for everyone on the stage for controlling sound for the match song sound. It connecting to the mixing control by the 2 inch - 6.5 inch jack. But it not connecting to mixing control straigth, A jack is connecting with AMP and monitor then it have a 6.5 inch jack from any AMP and monitor to mixing control. And done this network complete. When you playing a music on the stage, staff can mixing your sound to perfect song sound.

FLASH MEMORY

Flash Memory (sometimes called "flash RAM") is a type of constantly powered nonvolatile memory that can be erased and reprogrammed in units of memory called blocks. It is a variation of electrically erasable programmable read-only memory (EEPROM) which, unlike flash memory, is erased and rewritten at the byte level, which is slower than flash memory updating. Flash memory is often used to hold control code such as the basic input/output system (BIOS) in a personal computer. When BIOS needs to be changed (rewritten), the flash memory can be written to in block (rather than byte) sizes, making it easy to update. On the other hand, flash memory is not useful as random access memory (RAM) because RAM needs to be addressable at the byte (not the block) level. Flash Memory gets its name because the microchip is so organized that a section of memory cells are erased in a single action or "flash." The erasure is caused by tunneling in which electrons pierce through a thin dielectric material to remove an electronic charge from a floating gate associated with each memory cell. Intel offers a form of flash memory that holds two bits (rather than one) in each memory cell, thus doubling the capacity of memory without a corresponding increase in price. Flash memory is used in digital cellular phones, digital cameras, LAN switches, PC Cards for notebook computers, digital set-up boxes, embedded controllers, and other devices.

COMPUTER ANIMATION

COMPUTER ANIMATION Computer animation is the process used for generating animated images by using computer graphics. The more general termcomputer generated imagery encompasses both static scenes and dynamic images, while computer animation only refers to moving images. Modern computer animation usually uses 3D computer graphics, although 2D computer graphics are still used for stylistic, low bandwidth, and faster real-time renderings. Sometimes the target of the animation is the computer itself, but sometimes the target is another medium, such as film. Computer animation is essentially a digital successor to the stop motion techniques used in traditional animation with 3D models and frame-by-frame animation of 2D illustrations. Computer generated animations are more controllable than other more physically based processes, such as constructing miniatures for effects shots or hiring extras for crowd scenes, and because it allows the creation of images that would not be feasible using any other technology. It can also allow a single graphic artist to produce such content without the use of actors, expensive set pieces, or props. To create the illusion of movement, an image is displayed on the computer screen and repeatedly replaced by a new image that is similar to it, but advanced slightly in time (usually at a rate of 24 or 30 frames/second). This technique is identical to how the illusion of movement is achieved with television and motion pictures. For 3D animations, objects (models) are built on the computer monitor (modeled) and 3D figures are rigged with a virtual skeleton. For 2D figure animations, separate objects (illustrations) and separate transparent layers are used, with or without a virtual skeleton. Then the limbs, eyes, mouth, clothes, etc. of the figure are moved by the animator onkey frames. The differences in appearance between key frames are automatically calculated by the computer in a process known as tweening or morphing. Finally, the animation is rendered. For 3D animations, all frames must be rendered after modeling is complete. For 2D vector animations, the rendering process is the key frame illustration process, while tweened frames are rendered as needed. For pre-recorded presentations, the rendered frames are transferred to a different format or medium such as film or digital video. The frames may also be rendered in real time as they are presented to the end-user audience. Low bandwidth animations transmitted via the internet (e.g. 2D Flash, X3D) often use software on the end-users computer to render in real time as an alternative to streaming or pre-loaded high bandwidth animations. A SIMPLE EXAMPLE

COMPUTER PERIPHERALS

Computer peripherals are add-on hardware to the computer to expand its abilities or improve its performance. By adding memory, computers are able to perform a lot better, or by adding video cards, the computers graphics create more detail. These are just some of the peripherals, although there is a lot more you can put on your PC, some of them may not be compatible. Compatibility maybe an issue to some of the peripherals and may even cause the worst outcome – the PC refuses to boot or the PC refuses to recognise the peripheral being added. The easiest way to solve that would be figuring out where it started and you can start from there. Narrow down the problem and re-check the connections – specially the cards you just added-in. Checking the wires and screws make a difference. And everytime you install a new add-on card, and it suppose to be plug-and-play but it is not, maybe because you made a mistake in the installation process. Do not panic. Go through the whole process again and then try ones more. If still nothing is solve then maybe there might be a compatibility problem. Technically, every piece of hardware inside your PC requires a driver to communicate and function with the operating system, the software applications, and other hardware components in your computer. Software drivers basically translate messages from and to the hardware in question and the operating system, allowing your computer system to work as a whole— theoretically. Generally, though appearances may be deceiving, any computer system is actually made up of a bunch of specialized pieces that do not communicate the low level language of other peripherals and, therefore, needs a great deal of translation to be able to talk and work effectively with them. These facts may not solve all the hardware problems you may run into, however, they should solve a good number of them. The important thing to remember when trying to do any troubleshooting job, is that computers really are just logical devices and there is always a logical reason behind why things just not suppose to react the way they are. Finding what is that reason and then putting the right solution is not always easy, but if you approach the problem logically and work through it step-by-step, there is a very good chance you will be able to solve it by yourself.Examples are Expansion
