[] This brings up a UNIX signal question: >From: wmartin@brl-tgr.ARPA (Will Martin ) >Subject: "Nuclear Event Detector" >Newsgroups: net.analog,net.misc >I have gotten two ads in the mail so far for a product I find very >strange. At first, I wondered if this was some kind of elaborate joke >or hoax, but the product brochures are professionally done, utterly >serious in tone, and seem to be completely legitimate. Yet, either I >just have no concept of the engineering behind the product, or the thing >really is completely incomprehensible. > >It is nothing much to look at -- a circuit in a multi-pin (round pin) >package, and it is called the HSN-3000 High Speed Hybrid Nuclear Event >Detector. The first brochure I got was titled "Certified Circumvention >for Power Shutdown", and the second, largely similar, is titled, >"Certified Circumvention for Processor Shutdown/Restart". The company >making this is IRT Corporation, Electronic Systems Division, 3030 Callan >Road, San Diego, CA 92121 (619) 450-4343, x 527. Their slogan is "The >Experts in Nuclear Survivability". Well whats the consensus: SIG_NUKE ?. When the NED (Nuclear Event Detect) line goes low an 'event' has occured. My unix question is: Should SIG_NUKE be catchable?. Maybe you might have time to start sync()ing the disks. What good they will be is another issue. Hedley Rainnie hedley@alaya cmcl2!alaya!hedley
