Quite some years ago I suggested that a customer mirror all his data, rent a SR-71 Blackbird, load all the mirrored volumes into it and fly his data across the country. This was in response to his anger that it would take years at that time to move all his data across the country via the internet of the time.

His sales rep totally lost his cool in the meeting although the customer finally realized the limitations of networks and physics.

Ah Richard, you've kicked my brain drip pan with your 'birdie' comment.

In WWII when radar was being first used, the operators did not know if the radar was actually working when they had no targets. The solution was to use a crystal radio, no power needed, and listen for the RF pulse to go out. The outgoing RF pulse in the crystal radio sounded like a bird chirp. When I worked on a radar in the late '70s at TI, there was a signal called 'chirp' and one called 'chirp gate' that triggered the outbound pulse of RF.

Another such story is that of telephony where the wires names, at least in the USA, were referred to as 'tip', 'ring', and 'sleeve'. 'Tip' and 'ring' were the talking pair and 'sleeve' was a control ground. On the old so called cord boards, the incoming circuit was a number of jacks with cords attached and a field of sockets connecting to a end user. The operator would touch the 'tip' of the jack to the socket which was the 'sleeve' connection and if the end user was not using his phone, there would be no so called busy tone. The so called busy tone was, again in the USA, a 60Hz tone produced by the unbalanced line, 'tip' and 'ring', when one side was grounded. In the mid '70s, even the newest computerised telephone switches I worked on used 'tip', 'ring', and 'sleeve' or 'sleeve ground'

And then there was Tektronix schematics that would have somebody riding a bicycle down a circuit here and there.

Thanks for triggering such fond memoires Richard,

Richard and Keith,

I was too lazy to go edit the Hosts file on my own and your two notes did it all for me.

By the time I went back into BoincTasks, it had cleared all the files in retry mode that had been sitting there.

Thanks!

I drove from Woodland Park, CO up to Nebraska using back roads both ways. About 30 miles north of Scottsbluff was the centerline of totality along a dirt road between State Highways 29 and 71. Lots of folks parked along the dirt road but there was no problem finding a spot to pull off to observe.

The pale light preceding totality was really unusual and the drop in temps enough to pull on my vest.

Totality was really abrupt at my location. I kept looking to the west and really never saw it coming, very flat country western Nebraska. The time of totality was about 2.5 minutes and the so called diamond ring effect coming out of totality was really striking.

The trip home was about 3 hours longer than the trip out, well over 2 hours to cover 12 miles was the worst part.

Never having experienced a total eclipse in my first 65 years of life, this was definitely one of my top 10 life experiences.

I will admit that I did not read all the materials pointed to in the various places.

That said, I find myself troubled by the statement: "Its goal is to let us finish the current SETI@home experiment".

This sounds like the end of SETI@home.

I'm a bit tired and low on my glucose levels and I hope I'm not jumping to conclusions so please tell me that I'm off in the weeds.

Jord,

I congratulate you on a decade of moderation!

I know I could not do that service for that long, no patience for it. I'm so glad you do have what it takes.
