I'll stand behind everything I do and take full responsibility for it,
but when someone starts messing with my stuff, then the guarantee
expires. It's very simple, but obviously very difficult for crybabies
like you, who need to have their asses continually wiped for them to
understand.

As noted, *good* designers allow for what *could* happen to their
circuits under sub-optimal circumstances. 'John Fields' filed under
'do not employ'...................

Heh... Like what you say matters? ALL the stuff I get paid for works,
my clients are happy campers, and when they want modifications or
changes, guess what? They call _me_ because they know the work will
be done carefully and properly.

You, on the other hand, seem to blithely advocate the blind peppering
of pullups everywhere, whether they're needed or not, just because
that gives you the warm fuzzies. Pure waste and idiocy as far as I'm
concerned.

Just for grins, think about this: Say that you've designed a piece of
equipment using Pinkerton's Rule, (which mandates that pullups be hung
from every possible port) and that even though it wasn't designed to
operate in a high-EMI environment, it nonetheless finds itself in one.

Now, depending on the locations of the pullups and the length of trace
between them and their associated ports, the pullups could do more
harm than good. So now, by not having considered the possibility that
your equipment might be taken into a high-EMI environment and then,
during the design, taking whatever measures necessary to make it
immune from EMI you must admit that you didn't execute the design
properly and, therefore, come to the conclusion that you are a bad
designer.

So, you agree that all likely abuses of your design should be taken
into consideration before you sign it off. Thanks for your admission
that you're an incompetent asshole.

Damn, but you're dense, Pinkerton. I've never said that all likely
abuses _shouldn't_ be taken into consideration, all I said is that
there are limits, and the example I gave above was to prove a point;
namely, that by indiscriminately shoving crap into a design because it
makes you think that you've smugly covered all bases, you'll not only
make build costs higher, you could very well be buying yourself
trouble downstream because you didn't (or, in your case, _couldn't_)
consider one of the consequences of your misguided design philosophy.
As for the "Thanks for your admission that you're an incompetent
asshole." part, I can only assume that since you didn't have a valid
argument you had to revert to subterfuge and crudity in order to try
to derail the thread. Well, I'll have you know we run a fine,
upstanding newsgroup here and we don't appreciate that kind of cheesy
behavior from rat-hole residents like you who come over here looking
for handouts and spare change, harrumpff!!!

You'll have to ignore J.F.'s rants. I caught him leaving out a pullup
once, and he got all pi$$ed off at me and cursed me out.

I'll have to keep on him about that. [snip]

Hmm... I don't usually respond negatively to technical corrections
unless they're accompanied by a slap, but I do recall that you're
usually ready to come across with some smartass remark whenever you
think you can get away with it. If such wasn't the case, then I
apologize and thank you for the correction.

Omigod, a smart-arse on usenet.... that'll be one for the record books.

I've pointed out a number of (IMO) typo's in JFs posted circuits, and
received only polite replies.

But once he got all bent out of shape, thinking I was deriding the use
of a 555 (which I wasnt, leading me to question his reading comprehension).

OTOH he wrote a fabulous waffly story about comparator hysteresis on 14
june 2004, which I printed to a PDF (yay for PDF995) and kept, so I dont
have to explain it to others yet again. So he's cetainly not an idiot,
but perhaps a bit touchy.

I do wish he and robert (oops, Fred Bloggs) would leave Larry alone
though. What a colossal waste of bandwidth, and talent.

Cheers
Terry
