Jim Hall
Jim Hall is an open source software developer and advocate. His first
contribution to open source was in 1993 with a patch to GNU Emacs, but
he is probably best known for his work on FreeDOS, the open source
version of the DOS operating system, and for his work on usability in
open source software. In addition to writing open source software, Jim
also writes about open source software, including Both.org and All
Things Open, and about technical writing at Technically We Write.
