  • Philips Multimedia Center
    Sr. Systems Architect
    Philips Multimedia Center Dec 1995 - Mar 1999
    Amsterdam, Noord-Holland, Nl
    The DVX-8000 was a PC-based media center that was way before its time. Imagine a cross between a home-theater-in-a-box and Windows Media Center, but running on Windows 95. Caused a stir in the Home Theater industry at launch, featured on the cover of six trade magazines.The Philips Pronto consumer IR remote was my baby, from concept & business plan, though to shipping product. Wildly successful, it sold through the first quarter’s production in 3 weeks. It became a new product line and a source of OEM business for Philips. The SmartTalk home A/V control protocol became the HAVi and HomeAPI standards. The UPnP and Jini standards also shared a suspiciously strong resemblance to elements of SmartTalk.

    Windsor, Berkshire, Gb
    Key engineer on distributed virtual AppleShare file server. Product displaced the market leader in a matter of months and the company was acquired by Novell soon after. Elements of the technology found their way into versions of NetWare.Developed a mechanism to run an faceless application 'in the background' under System 6 (both single Finder and MultiFinder).Developed a mechanism to make the Macintosh file system re-entrant. The file system would have deadlocked without it, and the product would not have been possible.Developed mechanism to simulate a 'virtual' network node, allowing network traffic to be identified and intercepted before reaching the network. This provided large performance improvements (factors of 3-5) and reduced code complexity.

    Sr. Software Engineer
    Insignia Solutions Ltd. May 1987 - Jul 1989
    Us
    Ported SoftPC from Sun 3 to the Macintosh, the first non-UNIX version. Port was complex due to the absence of UNIX services (like virtual memory) on the Macintosh. Within six months the product contributed over 50% of the company's revenues and provided the lion's share for a number of years.Developed a new processor emulation (of the Intel iAPX 286) with a reduced memory footprint and host processor requirements, resulting in successful products for the Macintosh Portable and other popular low-end Macintoshes. This emulator was also used as the foundation for the NeXT and later Macintosh versions of SoftPC.Designed and implemented a set of MS-Windows device drivers which used an emulation 'back door' to let Windows drive the host display system as an intelligent accelerated graphics card. This prototype eventually resulted in 'SoftWindows', a product Apple chose to bundle with several Power Macintosh models at launch.
