    I can't work out who you are plonking. While more than one of the 
posters on this thread seem worthy of a good plonk, by not including 
sufficient context, you've left me feeling puzzled. Is there a guideline 
for this in basic netiquette?

You're right, my apologies.  Dwight Hutto is the one I plonked.  His 
signal to noise ratio seems incredibly low.

alex23 can definitely be abrasive, but his ratio is high.

(Now I'm wondering what that says about me as far as who I agree with 
and why... I'll have to think about that.)

Is this just because of the lack of context, or because of the content
of my response to the OP following the question?

And with all the netiquette talk being passed around, why isn't this a
new thread instead of hijacking the OP's original question, and
engaging in bickering about netiquette that goes
on all the time?

And it seems redundant to argue this topic other than to comment, and
let it pass, unless there's seems to be a legitimate reason why
someone 'disobeyed' posting policy.

You can call me David. I go by my middle name.

And it seem to me I made some valid points about a few simple trimming
of postings, that didn't seem necessary in the context of a small
quick conversation.

If you want to be known as David, why do you give your name as Dwight? In 
your email client or newsreader, set your name as David and attributions 
will be to David, and people will know to call you David.

Otherwise, people will continue to call you Dwight.

You're most often going to be addressed by the name that's given in
your post headers. In this case "David" has been reduced to an
initial, and is visible only in your email address, whereas "Dwight"
is right there in your real-name.

 My sig says David, but it was just to let him know he can call me by
my used name.

It's the fact that I consider the entire conversation the context.
Reading the OP's being the primary, and things they responded
positively to.

There are other things that get mixed up as well, like not hitting the
... in gmail, and so that content doesn't show, or hitting reply,
instead of reply all, and things getting jumbled for the others
involved in the conversation.

Then there is the problem of people saying you posted too much of the
context, or not inline with the OP, just at the end, or top posting.

I try to keep it along the line of what the OP has read, and they know
the context in which it's meant.

The solution to "you quoted too much unnecessary verbiage" is not "quote 
nothing". It is quote only the parts that are relevant.

You're assuming that people read your posts immediately after they read 
the post you replied to. Always imagine that your reply will be read a 
week after the post you replied to. Do you still expect the reader to 
understand what you're talking about?

And a week is extremely generous too; these posts get archived on the
web. I *frequently* find myself hitting mailing list archives when
researching obscurities. This is also another good reason to post
follow-ups to the list, rather than in private email. You might never
be thanked, but somebody years down the track may find the question
and an associated answer.

I do grovellingly apologize for my appalling breach of netiquette.  I am 
of course assuming that the rules have changed and that it's now my 
responsibility to wade back through maybe a couple of hundred responses 
on a long thread to find the context.  I also guess that I'm never going 
to achieve my ambition of being a pot smoking hippy CEO of a web 
development company :(

Cheers usually implies you're an alcoholic pressing buttons, with the
half of rest of the coders on the net.

So don't give up hope, you might be able to take a medication that
doesn't impair your judgement with the side effects alcohol has,

And of course leaves you without the ability to read any of the
responses to say you were right in certain instances, so something
must be wrong with your mail reader, or your alcoholic mind.

Also, without reading the other posts, you're probably just placing in
a duplicate answer sometimes, which might make you seem like a copy
cat.

Mark,
Sometimes it is the style in which something is asked, and not what 
specifically is asked. ;)

Dwight/David: 
Not necessarily true if you happen to be from the UK (or maybe just England). 
It seems to be a cultural signature equivalent to "Thanks"--at least in the 
UK (not sure about other places).

Ok, I see it's for the case where they're equal.

The worst case is O(N) or N characters
the average case is O(1) or two characters.

For denial of service attacks or systems, that are NEVER allowed to fail 
the worst case is important.

For most other cases the average complexity counts.

However I still wonder for how many applications the complexity of 
string comparisons would be the limiting factor.

and of course if you ever do find an application where that worst case 
matters there's an easy way round it: just call intern() on all the strings 
when they are created.

For the comparison to be the limiting factor you have to be doing a lot of 
comparisons on the same string (otherwise creating the string would be the 
limiting factor), so at the expense of a single dictionary insertion when 
the string is created you can get guaranteed O(1) on all the comparisons.
