Re: [PSUBS-MAILIST] OSS
Sorry, I'm not sure I have introduced myself. You'll probably
kick me out when I do! I forgot that step since I have kept up
on events at the PSUBS.org webpage for almost three years, so I
felt I knew a lot of you...Ooops. My name is Warren D. Greenway
I'm not quite 22 years of age, and have had passion for subs since
reading 20,000 leagues in second grade. I am a professional Software
Engineer in Washington, having gone through intesive homeschool right
through college. I write embedded systems code for ultra low power
measuring instruments, my specialty being ultra small operating systems
which I write for custom applications. I am generally considered well
read, being a bit of a book worm who devours classics and anything on
subs or oceanography. I have been working in my present position for
3 years, and have been in the workplace full time for 6 years. Sorry...
I guess I'm what you'd call a "whipper-snapper", a "young-un", and such.
Warren.
