Björn Fahller has had an M.Sc in Computer Science and Engineering since 1994, and is working at Ericsson Business Networks AB with software for network management. He has been programming in C++ since 1992, and has also produced software with the dynamically typed Objective-C. He has been using OS/2 since the first public beta of 2.0, and has been programming for OS/2 since shortly after. His current thoughts for another OS/2 C++ frame work are about type-safe interprocess/thread communication, and he would also like making WPS classes as simple as programming for extended attributes now have become.
