It's onefang, not Onefang or OneFang. Why do wiki's prefer uppercasing names?
About onefang
I have been involved in computer programming since 1977, having held every position from code cutter to R & D manager. I have programmed every level of computing device except super computers, in one hundred programming languages (assembler to 4GL), and 13 operating systems. I have experience in a wide variety of application fields - scientific, multimedia, games, real time control, embedded, communications, security, finance, business, virtual worlds, Internet, and government. I even have experience in related non-programming jobs like electronic design, desktop publishing, technical writing, computer education, support, and manufacturing management. My sysadmin experience is almost as extensive.
