Re: [time-nuts] LightSquared in the news again

A gun generally has someone with a measure of training and discipline at the controls. The other 1% or 2% -- the gangbangers -- they will get guns anyway, regardless of legislation. Lightsquared is just bidness as usual in Washington D.C. as it is practiced these days. Give me money and I will

I used to run a multi-line BBS (Wildcat!) and may still have two multi-port serial interfaces. I know that one has eight com ports and the other can support 64 but only has 32 ports installed. Give me a day or two to dig them out (if I still have them) -- they were both working fine when removed

Re: [time-nuts] USGS: GPS for seismic work

Two things 1) - people in anechoic chambers will really notice the sound of their heartbeats as well as the s-sh-s-sh sound of the blood flowing through their heads. http://en.wikipedia.org/wiki/Anechoic_chamber They are designed to have complete sound absorption and are dead quiet.

Re: [time-nuts] Oh dear

These people are amazing. They refuse to do any kind of double-blind A/B testing. My favorite thing is that they are trying to extract the maximum fidelity from an album or CD that was recorded in a studio with little or no AC power conditioning, whose recording consoles were wired with the

I am on the Tesla email list and people there have noted that some of the black plumbing pipe actually has carbon black added to it -- this renders the pipe conductive and not good for a Tesla secondary form. Would not be good for RF either. Dave -Original Message- From:
