Christopher Dunn (computer Enthusiast)
Christopher Dunn is a computer enthusiast noted for his involvement with CompuServe, and for the first high-profile online courtship leading to marriage in the United States. CompuServe contributions Around 1980, Dunn discovered CompuServe, an early online service popular with owners of 8-bit microcomputers. He served as the sysop of CBIG, a special interest group for users of CompuServe's CB Simulator chat service, where he went by the handle "Chrisdos". Dunn was the author of MU, an unofficial menu and mail notification program that ran on CompuServe's DEC PDP servers. (By 1984, it was no longer possible for customers to install and run server-side programs; MU was the sole exception.) In 1985, Dunn authored CBterm/C64, a terminal emulator for the Commodore 64 noted for its ability to directly display CompuServe's RLE graphics. Online dating In 1982, Dunn met Pamela Jensen through the CB Simulator. At the time, the 26-year-old Dunn lived in Queens, where he d ...

Run-length Encoding
Run-length encoding (RLE) is a form of lossless data compression in which ''runs'' of data (sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is most efficient on data that contains many such runs, for example, simple graphic images such as icons, line drawings, Conway's Game of Life, and animations. For files that do not have many runs, RLE could increase the file size. RLE may also be used to refer to an early graphics file format supported by CompuServe for compressing black and white images, but was widely supplanted by their later Graphics Interchange Format (GIF). RLE also refers to a little-used image format in Windows 3.x, with the extension rle, which is a run-length encoded bitmap, used to compress the Windows 3.x startup screen. Example Consider a screen containing plain black text on a solid white background. There will be many long runs of white pixe ...

Online Wedding
Something most often seen in massively multiplayer online role-playing games (MMORPGs), online weddings date all the way back to the beginning of online communities and early online games such as MUDs. Two people who wish their avatars, or characters, to be married will create an event that resembles a standard wedding. This became very popular with the introduction of ''Ultima Online'', which not only provided rings, outfits and decorations, but sometimes even Gamemasters to officiate. This tradition has carried forward into several other MMORPGs and virtual communities. Some games offer special Bonuses to players who participate in a virtual wedding. In many cases the participants do not know each other outside the virtual community. Some couples may not even know each other's true name, gender, etc. Some do, in fact, extend this union outside the virtual, but most do not. There is no legal recognition for virtual marriages. Some couples have joined in what appear to be legally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The ''Chicago Tribune'' is a daily newspaper based in Chicago, Illinois, United States, owned by Tribune Publishing.

20/20 (U
Visual acuity (VA) commonly refers to the clarity of vision, but technically rates an examinee's ability to recognize small details with precision. Visual acuity is dependent on optical and neural factors, i.e. (1) the sharpness of the retinal image within the eye, (2) the health and functioning of the retina, and (3) the sensitivity of the interpretative faculty of the brain. The most commonly referred visual acuity is the far acuity (e.g. 6/6 or 20/20 acuity), which describes the examinee's ability to recognize small details at a far distance, and is relevant to people with myopia; however, for people with hyperopia, the near acuity is used instead to describe the examinee's ability to recognize small details at a near distance. A common cause of low visual acuity is refractive error (ametropia), errors in how the light is refracted in the eyeball, and errors in how the retinal image is interpreted by the brain. The latter is the primary cause for low vision in people with al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Phil Donahue Show
''The Phil Donahue Show'', also known as ''Donahue'', is an American television talk show hosted by Phil Donahue that ran for 26 years on national television. Its run was preceded by three years of local broadcast on WLWD in Dayton, Ohio, and it was broadcast nationwide between 1970 and 1996. History Dayton start In 1967, Phil Donahue left his positions as news reporter and interviewer at WHIO radio and television in Dayton to go into the stations' sales department.

The station’s weekday variety, music and chat program, ''The Johnny Gilbert Show'', ended suddenly, when Gilbert left on short notice for a hosting job in New York City. WLWD named Donahue to replace Gilbert, keeping the live format and studio audience. But Donahue decided to take the show in a new direction. He focused on one guest or topic for the entire hour and invited the audience to ask question ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
