Just to further make it easy to confuse the two, the Forth-inventor Chuck Moore is also involved in chip design these days (at Green Arrays - a company doing embedded heavily multi-core chips running a forth-like instruction set)
I also wondered for a while (checking wikipedia and work...). May he rest in peace, even if from that little article I didn't get to know what advancements he was responsible of (and I'm now quite curious about)
This is terrible news. I got to work with Chuck Moore in grad school. I was a PhD student when he was a senior member of our research group. At the time he'd already led the design of IBM's Power4, the first multicore processor.
The tap water in Silicon Valley is generally terrible - a legacy of [a] not enough water in California and [b] the industrial legacy of turning "The Valley of the Heart's Delight" into a manufacturing center.
