edit Featured articleTRS-80 was Tandy Corporation's desktop microcomputer model line, sold through Tandy's Radio Shack stores in the late 1970s and early 1980s. The first units, ordered unseen, were delivered in November 1977, and rolled out to the stores the third week of December. The line won popularity with hobbyists, home users, and small-businesses. Tandy Corporation's leading position in what Byte Magazine called the "1977 Trinity" ( Apple, Commodore and Tandy) had much to do with Tandy's retailing the computer through more than 3000 of its Radio Shack (Tandy in Europe) storefronts. [1] Notable features of the original TRS-80 included its full-stroke QWERTY keyboard, small size, its Floating Point BASIC programming language, an included monitor, and a starting price of $600. [2] The pre-release price was $500 and a $50 deposit was required, with a money back guarantee at time of delivery.

The length of the lines are indicative of the delay between those two nodes. This graph represents less than 30% of the Class C networks reachable by the data collection program in early 2005. Lines are color-coded according to their corresponding RFC 1918.

edit Selected biographyFrances Elizabeth "Fran" Allen
b. 1932
Fran Allen is an American computing scientist and pioneer in the field of optimizing compilers. Her achievements include seminal work in compilers, code optimization, and parallelization. She also had a role in intelligence work on programming languages and security codes for the National Security Agency.Allen is a fellow of the IEEE, the Association for Computing Machinery (ACM) and the Computer History Museum. She is currently on the Computer Science and Telecommunications Board, the Computer Research Associates (CRA) board and National Science Foundation's CISE Advisory Board. She is a member of the National Academy of Engineering, the American Academy of Arts and Sciences and the American Philosophical Society. In 1997, Allen was inducted into the WITI Hall of Fame. She retired from IBM in 2002 and won the Augusta Ada Lovelace Award that year from the Association for Women in Computing. In 2007 Allen was recognized for her work in high performance computing when she received the A.M. Turing Award for 2006. She became the first woman recipient in the forty year history of the award which is considered the Nobel Prize for computing and is given by the Association for Computing Machinery. In interviews following the award she hoped it would give more "opportunities for women in science, computing and engineering". In 2009 she was awarded an honorary doctor of science degree from McGill university for "pioneering contributions to the theory and practice of optimizing compiler techniques that laid the foundation for modern optimizing compilers and automatic parallel execution". |
