We usually agree John, but this part is not so stupid at all.

Since AOL dropped its Usenet service, all of the idiots seem to have migrated
to Google Groups. Far worse, Google insists on accomidating spammers.
Sometimes I think that Google is trying to kill the Usenet because it has no way
of reliably collecting ad revenue from it. Since Google Mail does such a good
job of blocking spam, there is no doubt that Google could do the same to Groups
if it served their corporate plan. Since the Google spam seems to come in
waves, I may or may not have Google blocked on any given week.

The Google idiots I can put up with, but spammers are the lowest form of
sub-human life.

The problem is more a case of Google using their anti-spam capability only on
incoming mail. They don't even use it on their outgoing EMAIL! My email spam
has reached a point where nearly 30% comes from a Google server. Of the spam
received just today in my mailbox (I haven't even checked the spamtraps, yet)
exactly half (4 out of 8) came from a Google server.

If Google were to apply their extensive anti-spam capability to all their
outgoing EMAIL and USENET postings, this problem would insignificant. My
gmail address doesn't get spammed like that (but just in case, you can
figure it out via my ham radio callsign if you wish).

I agree. And there are even a few decent smart people who have chosen to use
the Google Groups web interface to submit mail, too. I tried it myself a few
times and found it semi-usable. I find the reading to be a bit harder there.
I should go back and look again to see if the Usenet spam we get is also seen
there (since I last looked well before the spam outbreak at Google).

Interesting device. The closest I've seen to that was a set of locks that
threw bolts in front of breakers you should not operate. To make sure you
could not operate two breakers in conflicting states, the key would stay
captive in each lock depending on whether or not the bolt it threw was or
wasn't blocking the circuit breaker paddle.

It may sound complex, but it was just a bunch of panel mount deadbolts
attached to the face of the breaker panel, far far cheaper than some weird
rotary switch.

I recently saw a keyed-interlock - in a new industrial setting -
where you could remove the key - without the switch being
turned OFF ... a little extra pressure in turning the key
resulted in the "bowing" of the interlock mounting steel
( maybe 1/16 inch ) but it was enough to complete
the key rotation to the point where the key came out.
.. the panels are now replaced.
