I am no longer a graybeard. Both my beard and ponytail are now white. A lot of chicks think that's hot, so I'm happy. Retirement can be fun.
My original UID was in the high 5 digits, I don't remember it or what I used as a login name, so while slashdot would still have it on record, it has been lost since 2002. I screwed up when I moved that year. I found my backup disks about 5 years later. Lesson learned: some things you need to pack yourself, rather than relying on friends or a soon-to-be exwife.
My second account was under the name "MysticGoat" since I wanted separation between my career and my private life. That account is still around, but dormant, as #582871. I started using it in June 2002, and other than just now checking to see if it is still there, I've not done anything with it for years.
I began my current account as will.woodhull about 5 years ago when I decided that I was so close to retirement that I didn't need to protect my private life from prying cow-orkers.
Other relevant experience: first course in programming: 1972 Summer elective in Fortran. First computer: in 1980, an Apple ][+. Degree in Business, Computer Programming: in 1988, programming experience was split evenly between HP Business BASIC and COBOL, but it turns out the courses in business law and accounting have had more lasting value. Self-employment: building and supporting custom computers and small networks, 1988 to 1995 full time, then tapering part time until out of that dead-end line of work in 2002.
You really can't trust the /. UID for estimating age or experience. A lot of us who have been doing this for a quarter century or more have had reasons to abandon old /. accounts and start new ones from time to time.
Another thing: no matter how much experience you may have on your own computers, it does not compare with the experience gained from supporting other person's hardware and software.
