Thanks Glen for that gem of information. Certainly anyone who has ever listened to the warbling tone of a group delay test signal will never forget it....

Hi Rene, thanks. I did put in the original text that this was a Grey-headed Albatross chick, but Maxz edited it out, so blame him. Marion was a breeding ground for 4 species of Albatross - Wandering Albatross (diomedia exulans) which are the largest albatrosses - windspan 3 metres; Grey-headed albatross (Diomedia chrysotoma) and two closeley rlated species of Sooty albatross (dark-mantled (Pheobetria fusca) and light-mantled (phoebetria palpebrata)). And no, didn't remember the latin names, I still have my bird book. The Grey-headeds used to next on a high ridge (imaginatively called Grey-headed Albatross ridge) and the chicks like the one shown in the picture occasionally used to fall or get blown off into the valley below. If we saw any that were still stong we used to haul them up the ridge again (which is what I was doing in the photo). Whether this was ever successful I am not sure - don't know if the parent birds would find the chick if it was on the wrong nest. Sorry, probably more than you wanted there....

That reminds me of the joke about the man who walks into a bar with a pig under his arm... ... and the barman says "My, that certainly is a handsome looking pig you have there; where did you get him?" ... and the pig replies "I won him in a raffle!"

Good story! As for the 1004 Hz, my limited recall is that a test tone of 1000 Hz caused a problem in a T1 circuit (1.544 Mb/s in North America). Forget if this caused false sync or alarm, but the problem went away when the test frequency was shifted to 1004 Hz. Perhaps somebody with a better memory can add to this. 400 Hz was also used as a test tone in some cases, the reason being that the lower pitch was far less annoying to technicians that had to listen to it.

David -- who is your friend in the picture on Marion Island? Was this a wild bird that you had surprised ... or a pet that you always carried around (just in case you needed a "conversational starter" when you went into a bar)? :-)

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
