Toyotas and neutrons

[John Teller]

Writing as much code as I have for satellite systems, most of which had 
to live without radiation hardened and/or EDAC memory, I just got used 
to not trusting that stuff I had written to memory wouldn't stay that way.

It's served me in good stead while working with some X parts we recently 
obtained from a supplier that came with an undisclosed read/write 
problem.  The first batch of production ready parts do not have this 
problem.  I was able to deal with the glitch-prone X parts effectively 
enough to provide our beta customers with products they could start 
testing with.  We're not planning on removing that code for the fixed parts!
