Advanced Mac OS X Instructor Mark Dalrymple, author of Advanced Mac OS X Programming, has been a Macintosh programmer since 1985 and a professional unix programmer since 1990.
On the Mac side of things, Mark has contributed to the AOL 3.0 client and was chief architect of an internal publishing tool that interfaced with both the Mac AOL client and the AOL proprietary publishing infrastructure, all using C++. On the unix side, he has contributed code and developer documentation to the Galaxy cross-platform toolkit (supporting more than 20 different unix platforms, as well as Windows, the Mac, and OpenVMS) using C and C++.
While at AOL, Mark was also technical lead for the AOLserver team. AOLserver is a web application server implemented in C and Tcl which collectively across all AOL web properties was handling tens of thousands of hits per second on many different unix platforms (Linux, HP, SGI, Digital Alpha, Solaris).
