Re: [TUHS] What was your "Aha, Unix!" moment?

Tracy Kidder evokes different emotions around "the soul of a new machine" -To me, the book is great because its a humanist reading of technology choices. People matter. Careers are built on seemingly trivial decisions like the size of the average door frame in a lift in Tokyo. (a brief moment in the book, from memory) I always wished it had been written about Digital Equipment and not Data General, because the only DG box I worked on (a Nova) was a dog. I know one person who came from Australia (UQ) to Maynard, to track the building of the Dec-10 destined for the campus. He had entertaining anecdotes about parking and weather. (australians are not naturally prepared for 2m of snow and the effect of parking in the wrong side of the snow shadow, which explains why the parking spots were empty for the visitor to claim) -I think the birth of the pdp-8 and pdp-11 would be fascinating. I was told the queue to sign up for pdp-8 at the IFIP floor show in the 60s in Edinburgh was a mile long: people were dog tired of walking card decks over to central computing facilities and the offer of a deskside or even desktop (if your desk was strong enough) compute engine for stats and maths and process control... Sub-floor radius limits made it hard to retrofit a Cray into the UQ machine room because the piping radii had been done for the IBM mainframe. We had to lift the raised floor for the flourinert piping. 400Hz voltage demanded a spinning metal regenerator to do frequency conversion from the Australian wallplate voltage/frequency. Our groundplane was inadequate. The Tops-10 box, the cluster of Vaxen, were completely oblivious to most of this: they did air cooling through floor venting, thats really all that mattered in their machine-room. It was the one we chose to fit the comms racks because it was the least pain to work in, and the nearest to the hosts which could actually use Internet protocols trivially on UTP or thinwire. (the IBM required us to buy a $10,000 PC to fit the line card which translated TCP/IP into IBM networking and was possibly the last piece of "thickwire" ethernet we owned) -G
