JPEG (/ˈdʒeɪpɛɡ/ JAY-peg) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.
The term "JPEG" is an abbreviation for the Joint Photographic Experts Group, which created the standard. The MIME media type for JPEG is image/jpeg, except in older Internet Explorer versions, which provides a MIME type of image/pjpeg when uploading JPEG images. JPEG files usually have a filename extension of .jpg or .jpeg.
The Graphical Environment Manager (GEM) was an operating environment created by Digital Research, Inc. (DRI) for use with the DOS operating system on the Intel 8088 and Motorola 68000 microprocessors.
GEM is known primarily as the graphical user interface (GUI) for the Atari ST series of computers, and was also supplied with a series of IBM PC-compatible computers from Amstrad. It also was available for standard IBM PC, at the time when the 6 MHz IBM PC AT (and the very concept of a GUI) was brand new. It was the core for a small number of DOS programs, the most notable being Ventura Publisher. It was ported to a number of other computers that previously lacked graphical interfaces, but never gained popularity on those platforms. DRI also produced FlexGem for their FlexOS real-time operating system.
GEM started life at DRI as a more general purpose graphics library known as GSX (Graphics System eXtension), written by a team led by Don Heiskell. Lee Lorenzen (at Graphic Software Systems, Inc.) who had recently left Xerox PARC (birthplace of the GUI) wrote much of the code. GSX was essentially a DRI-specific implementation of the GKS graphics standard proposed in the late 1970s. GSX was intended to allow DRI to write graphics programs (charting, etc.) for any of the platforms CP/M-80, CP/M-86 and MS-DOS (NEC APC-III) would run on, a task that would otherwise require considerable effort to port due to the large differences in graphics hardware (and concepts) between the various systems of that era.
Google Chrome Apps are web applications that run on the Google Chrome web browser. Chrome apps can be obtained from the Chrome Web Store where apps, extensions, and themes can be installed or bought. There are two types of apps, hosted and packaged, which have different locations of their executable and are targeted at different use cases.
Chrome apps can be hosted or packaged. Hosted apps have their background web pages on a remote server and the app acts like a bookmark or shortcut.
Packaged apps were launched on September 5, 2013. They have features very similar to a native desktop app, namely offline capable (by default), can interact with hardware devices, and can access local storage. Packaged apps are not confined to the regular Chrome interface and can display without a classic window menu and operating system user interface elements.
Hosted apps are the first developed types of Chrome apps. They contain a single manifest file that contains the URL and additional information about the app. Hosted apps are usually offline and are subject to regular web page security restrictions.
Lego (/ˈlɛɡoʊ/) is a line of plastic construction toys that are manufactured by The Lego Group, a privately held company based in Billund, Denmark. The company's flagship product, Lego, consists of colorful interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts. Lego pieces can be assembled and connected in many ways, to construct objects such as vehicles, buildings, and working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects.
The Lego Group began manufacturing the interlocking toy bricks in 1949. Since then a global Lego subculture has developed. Supporting movies, games, competitions, and six Legoland amusement parks have been developed under the brand. As of July 2015, 600 billion Lego parts had been produced.
In February 2015, Lego replaced Ferrari as Brand Finance's "world's most powerful brand".
The Lego Group began in the workshop of Ole Kirk Christiansen (1891–1958), a carpenter from Billund, Denmark, who began making wooden toys in 1932. In 1934, his company came to be called "Lego", derived from the Danish phrase leg godt, which means "play well". In 1947, Lego expanded to begin producing plastic toys. In 1949 Lego began producing, among other new products, an early version of the now familiar interlocking bricks, calling them "Automatic Binding Bricks". These bricks were based in part on the Kiddicraft Self-Locking Bricks, which were patented in the United Kingdom in 1939 and released in 1947. Lego modified the design of the Kiddicraft brick after examining a sample that they received from the supplier of an injection-molding machine that Lego purchased. The bricks, originally manufactured from cellulose acetate, were a development of the traditional stackable wooden blocks of the time.
Lego is a line of toys produced by the Lego Group consisting of interlocking plastic blocks.

Lego is a Sakalava musician who performs accordion music in the traditional style of the coastal regions of Madagascar. In addition to his acclaim as a musician, Lego is also known for having lost his sight as a child, and for being the half-brother of Malagasy superstar Rossy.
