[ale] Engineering Archaeology

As a young person more than once I’d heard of someone insulting someone else by saying "I’ve forgotten more than you’ll ever know!”

In my later years when I would speak to people about “the old days” and things such as RS232-C and/or Hayes modem commands I realized that while it was likely true I’d forget much of the detail it didn’t mean younger folks would never know more than I’d forgotten.   They would instead have no need for what I’d forgotten (for the most part) and eventually would learn things I’d never learn.  

More than once I’ve told people the reason I liked “System Administration” was that although my job titles might have changed the basic mission was the same however the knowledge and skills used evolved dramatically.   It meant I was constantly learning.

I contrasted that to my former accounting career.   It took a special mindset and intelligence to do that but it became “routine” as it didn’t change much.  I once told a boss “I feel both bored and burned out and it doesn’t seem reasonable that both would be true.

Retiring systems is like pulling teeth in many places.   Long after we migrated our main Production systems off HP-UX to Linux there was one application a manager insisted we keep running to allow access to history.   The only reason we finally got rid of those servers was because we had to move out of our original offices which included our own data center.   The new offices didn’t so we were moving much of our equipment to a remote data center.   We told that manager we wouldn’t have room for those HP-UX servers.

P.S.  HP-UX was my favorite UNIX variant.   IMO it was much superior to both AIX and Solaris.  I hated it when HP dumped the PA-RISC chips in favor of Intel based chips.

I remember that DEC often had "retirement" sessions for products that discussed:

o do we have any active support contracts?
o how does this retirement affect other still active products? 

o other things I have forgotten

I remember attending one of these sessions for "DECtape" (also known as "LincTape") a little round reel of tape that I LOVED when I was a student in 1969.   Programs that would take 30 minutes to load from paper tape would load in seconds using LinkTape, and you could store huge amounts of data on it.

As I said, I used this as a student in 1969, on a DEC Linc-8 computer, a blending of DEC's Linc computer and a PDP-8, but I know they were still active on PDP-7s, PDP-11s and PDP-8s (and probably more machines).   They were affordable, rugged and could easily fit in your (large) pocket. 

Years later came the "retirement" meeting for DECtape, and as people around the room representing various operating systems and service groups (including Ultrix) raised their hands and said that they were ready to pull the plug I realized that none of these people were OLD ENOUGH to actually have used DECtape.

So when it came to me, I told them what DECtape meant for a 19-year old university kid, and asked for a moment of silence for DECtape....and they gave it.

Unbeknownst  to me there was a person sitting in the back of the room taking notes for a book about DEC and its products who copied, almost word for word, what I said and a couple of years later in that book my story appeared.   Still later, in the computer museum that DEC had in Marlboro (which donated a lot of equipment and documentation to the Computer History Museum in California) there was an instance of a PDP-11 along with a DECtape display, and there on a panel were my words again.

One of my fears about e-books, the web and documentation that can disappear as easy as "rm -r *", is that we will lose a LOT of this information and not know where we came from and how we got here.

Ha! The project book "What this goddamn this is, how it works, and what we thinking when we built it" is NEVER part of the project and should be the first thing done!

Heh heh.  A very amusing essay. I personally myself set up wiki webs in two of the jobs I had over the years,and contributed extensively to others I found already in place. They're my personal favorite way of preserving this sort of thing.
