No, really: he was doing some psycho-acoustic thing comparing compressed to uncompressed for somebody, or improving on the fraunhoffer algorithms which became MP3. The point was, the rest of us had to listen to CDs and Ken had the complete works of Bach (or something) on a hard drive, which we were told he kept in the office, and played at home over a landline of some horrendously high bandwidth, un-imaginable speeds like a megabit, imagine, a MILLION of those suckers. How dare he. Thats more than the whole of queensland. I imagine the truth is much less interesting, and there was no major IPR fraud going on at the labs coding stuff as MP3 like we imagined, under the table. I imagine this would also have been a Datakit T-1. But surely that was a 1.44mbit carrier? T1 was smaller than E1 because europeans and asians learned to count to 32 not 24. -G On Wed, Jun 22, 2022 at 10:48 AM Rob Pike wrote: > > Plan 9 used Datakit as its network for quite a while.
