Software experience includes Acronis, Ghost, Windows (versions up to Win7), VMWare, Linux, programming in assembler and higher level languages, Rockbox programming (built and posted about the first 240GB Cowon X5 in 2010 (listening to music on it as I write this), and virtual memory systems. Jobs have included PC Tech and Systems Admin, currently I'm a CAD designer (2D and 3D with Autocad and Solidworks).

I was the first to post about using a RAMDISK for holding the pagefile.sys in 2002 (2cpu.com forums) to greatly improve performance on Windows NT based systems.

I currently use such a system on XP32 bit to allow 8GB (or more). Current system has 8GB, 3GB for the OS, 5GB for the RAMDISK on which the pagefile resides. Superspeed RAMDisk allows access to ram the OS can't see, and with some clever reg mods posted on oczforums ~2008, XP32 can be fast even with the Commit Charge well beyond the ~3GB visible to the OS. This trick allow multiple virtual machines to be run and at the same time have a hundred windows open, large HDTV file copy/moves (like 500 GB of files), while web browsing, movie watching, Photoshopping, etc. with ANY page fault delays, due to the ~5000GB/sec and ~500000 IO/sec provided by the pagefile being on a RAMDISK (again all on XP32). For security, I web browse most sites on a Linux VM running Firefox.

One additional benefit of a RAMDISK pagefile setup is rock solid stability. Any race conditions caused by paging delays that lead to an OS crash are GONE. I've run this setup on XP32 since 2011 and the performance and stability is excellent.

I also have experience with digital and analog electronics, microcontrollers, high power switching power supplies and motor controllers, and battery charging and management systems. I had the first CPU controlled Nicad peak detector on the RC model airplane market in 1993 (MicroPeaker) and I am a pioneer with high power brushless DC motors. I designed a PIC based 3 phase controller for an Aveox motor in 1993, all bit-banged PCM with RC control, eeprom, config, with only 2048 bytes available. I worked for Aveox in 1994 and assembled and tested the first high power Y wind motor marketed to hobbyists (Aveox 1412-7Y). The RC drones and electric 3D model airplanes available today were based on the evolution of that motor and its variants.
