Well, I do have a BNC male-male adapter, and some BNC cable. That should suffice as an extension.

Well, to drive this further off topic.... ;) All holidays are "made up." They are celebrations of this thing or that, lots of times an event. Nobody'd have thought of having a holiday before the thing happened, right? The difference with kwanzaa is that it's silly/stupid because it's (AFAIK) a celebration of racial identity which stems (IMO) from an insecurity of some type, where lots of other holidays are silly/stupid because they're celebrations of national identity (for instance) which stem (IMO) from an insecurity of some type :P Regards, Chris (who never understood the tendency of people to want to assign themselves to groups) Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '

The instructor on my ESD classes in the 80's probably read the same books and data sheets that yours did. You certainly wouldn't notice a few kV picked up by walking across a carpeted room if it had a few seconds to dissipate before you touched something that would discharge it instantly. I remember one school who had a lot of BBC Microcomupters in the mid-80's. All was well with them, until they had a building refurbishment, and the micros wer moved to a new room with carpet tiles. They had endless trouble after that, with machines resetting at odd times, misbehaving in unexpected ways, and so on. When one finally stopped working altogether and I was asked to look, I asked about the carpet. I suggested they mist it periodically with well-diluted carpet cleaner to reduce static, and the problems went away (I repaired the faulty machine -- it had a blown LS TTL chip, which may or may not have been coincidence). -- Pete Peter Turnbull Network Manager University of York

You probably shouldn't use WD-40.... Better to use a good type of grease. They forgot to install grease fittings.... : ) On a side note, we had a guy from IS about ready to lubricate the bearings on a hard drive once. The situation started with a work order to repair a "squeaking" hard-drive. The real problem was that some joker turned on the "audible network activity" setting on an X-terminal, and it was "chirping" every time it attempted to access the network. Some guy came in on a different shift, and thinking he was a computer expert, quickly came to the conclusion that the hard drive needed replacement because the bearings were shot. Being the budget-minded people we were, we suggested to him that rather than replacing the expensive hard drive, we would ask the Information Services group to send a technician to repair, rather than replace, the hard drive. When the technician arrived we showed him the work order, and demonstrated the "chirping" noise. He agreed with the conclusion of the guy who write the work order that the hard drive really was at fault, and we convinced him that he should take it to the facility maintenance people to have them install a grease fitting on the hard drive and to "lube it up". As he started to take the case off of the terminal we pointed out the network activity setting. We got a good laugh out of it.... - Matt At 10:43 AM 12/17/2001 -0700, you wrote: >For laughs, take a look at >http://www.help-net.com/computer%20buddies/pc911/clean_your_hard_drive.htm Matthew Sell Programmer On Time Support, Inc. www.ontimesupport.com (281) 296-6066 Join the Metrology Software discussion group METLIST! http://www.ontimesupport.com/cgi-bin/mojo/mojo.cgi "One World, One Web, One Program" - Microsoft Promotional Ad "Ein Volk, Ein Reich, Ein Fuhrer" - Adolf Hitler Many thanks for this tagline to a fellow RGVAC'er...

I this has already been mentioned, but also don't put boards ! in that have ! any sort of battery fitted or removeable labels you want to keep stuck ! on.... ! ! -- ! adrian ! Course, you could always remove the labels first, put them on wax paper, then stick them back on after drying. If the adhesive won't hold anymore, clear packing tape, trimmed to just a little bigger than the label, should work. And protect it too, since the label is most likely only paper. --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818

Should engineers be licensed (Was "Geeks")

What do they teach kids > these days ?? My guess is nothing. (Really... that's part of the reason I'm not in a hurry to get my degree) It's not that the couldn't teach anything, or that the "kids" couldn't learn if they tried, though, I think. It's more that they're too stupid to know that there's more to learning than showing up every day and reciting meaningless (to you) data. The really sad part is that schools are accommodating this attitude by adjusting their programs such that you really needn't (in fact, it becomes difficult to...) learn anything.
