Worked TI 9900, 8085, 8088, 370, H6024 assembly codes and various proprietary OS. Started doing *NIX in 1985, first *NIX internals class 1985 working for a vendor of the Tahoe architecture, doing FORTRAN, C, Ada, C++, VHDL, and Java in embedded real-time and sensor systems from microcontrollers through clusters of super-minicomputers to clusters of super-microcomputers. Database in scalable UNIX OLTP systems in the banking industry (ugh!) GUIs of various flavors up to Android. Yeah, I`ve done some stuff... still don`t know anything... Moore`s Law applied to software: Every eighteen months half of everything you know becomes obsolete. Recommendation for job security: Give away everything you know while it still has value and hope that people you work with will do the same. ©
