Don Hopkins

Don Hopkins is an artist and programmer specializing in human computer interaction and computer graphics and an alumnus of the University of Maryland and a former member of the University of Maryland Human – Computer Interaction Lab.

He inspired Richard Stallman, who described him as a "very imaginative fellow", to use the term copyleft. He coined Deep Crack as the name of the EFF DES cracker, and built "AJAXian" applications for the NeWS window system 17 years before the term was coined. He ported the SimCity computer game to several versions of Unix and developed a multi player version of SimCity for X11, did much of the core programming of The Sims, and developed robot control and personality simulation software for Will Wright's Stupid Fun Club.

He developed and refined pie menus for many platforms and applications including window managers, Emacs, SimCity and The Sims, and published a frequently cited paper about pie menus at CHI'88 with Jack Callahan, Ben Shneiderman and Mark Weiser. He has published many free software and open source implementations of pie menus for X10, X11, NeWS, Tcl/tk, ScriptX, ActiveX, JavaScript, OpenLaszlo, Python and OLPC, and also proprietary implementations for The Sims and the Palm Pilot.

Don Hopkins (baseball)

Donald Hopkins (born January 9, 1952) is an American former professional baseball player. An outfielder during his minor league baseball career, he was used almost exclusively as a pinch runner by the 1975 American League West Division champion Oakland Athletics. He stood 6 feet (1.8 m) tall and weighed 170 pounds (77 kg), batted left-handed and threw right-handed.

Although a native of West Point, Mississippi, Hopkins attended Benton Harbor High School in Michigan and was signed as an undrafted free agent by the Montreal Expos in 1970. A speedy baserunner, Hopkins stole over 40 bases four times in his minor league career, and was acquired the Athletics from Montreal just prior to the 1975 campaign. At the time, Oakland owner Charlie Finley — one of the early proponents of the designated hitter rule, adopted in the American League in 1973 — was also advocating the creation of the "designated runner" in baseball, and he regularly employed fast players on his 25-man roster to specialize in pinch running. Hopkins fulfilled that role during the 1975 season. He appeared in 82 games, largely pinch-running for future Baseball Hall of Fame member and veteran Billy Williams, who was Oakland's designated hitter. Hopkins stole 21 bases and scored 25 runs, but had only eight plate appearances. He drew two bases on balls and collected one hit, a single, off the Detroit Tigers' Fernando Arroyo in a lopsided, 16–4 Oakland win on July 22.
