In the early 1990s, I hired onto TechWorks as the firmware developer, working mostly on ethernet drivers. Later, I contributed to the GraceLAN suite of tools for network management. My tenure at TechWorks ended when the GraceLAN product line was sold off to Saber Software (which was soon after acquired by McAfee). When Saber bought GraceLAN, they also bought the development team–no matter what the Thirteenth Amendment says.
My consulting firm (with several partners, all GraceLAN alumni). Here I worked on everything from education software, to games*, to network connectivity.
*When MDK was bundled with the original iMac, it became my most widely published work (until Virtual Truck surpassed it→). Here is the Wikipedia article on MDK
I was employee number 13 at BroadJump, and one of three engineers (and team lead) who created Virtual Truck, the product that made the company profitable. Virtual Truck connected a PC or Mac to a broadband network (cable modem or DSL) in a couple of minutes by configuring network settings, saving the technician hours each day.
BroadJump was acquired by Motive Inc. while I was working there.
My first gig in consulting. Among my work here was the software in Fusion Data Systems' TokaMac accelerator cards. I'm not completely sure, but I believe I was the first in the world to get MacOS running on the Motorola 68040 processor–in 1990, almost a year before Apple released the Quadra models with the same CPU.
I worked on a team that provided design support for products that were already in production; the hardware equivalent of "bug fixes" in software. Among other things, I fixed a noise issue on the 68000 processor that had been an issue for years before my fix. (This is the division that was later spun off to form Freescale Semiconductor.)
I have done some things for my own edification or amusement, including a command-line program to convert between the number bases commonly used by programmers, and a recipe library that easily scales ingredients by the desired number of servings. A few projects are stored on GitHub.
