For those who don't know who Joel Spolsky is and what
stackoverflow.com is, it's a kind of question and answer site for
programmers founded by two blog authors, Spolsky and another person
called Jeff Atwood.
I used to use the site a lot but stopped posting because of stuff like
this:
http://stackoverflow.com/questions/815787/what-perl-regex-can-match-camelca=
se-words

apital letter?
I'll leave spotting the mistake here as an exercise for the reader.
What bothers me isn't the mistake so much as that someone has
"upvoted" the answer, and yet another person has wrongly stated it is
"equivalent to Brian's answer". Note that there is no way of knowing
who upvoted this answer. When I was posting on the site I repeatedly
saw wrong answers being upvoted, and had the experience of correct
answers I'd written being downvoted.
I suggest people steer clear of this kind of misinformation site.

I didn't filter this guy. Anybody else I should know about?
I'm new to plonking. How do I plonk somebody, because I really don't
want to see plonking responses?

Agreed. And being paid or not is orthogonal to this definition, what I
agree too.
I've thought a lot about all that thread (again). In case you would
have gone with a quotation there would be almost nothing to say. But
you've gone with the definition. Pretty fair. But then I have a
problem with the conclusion.
Consider this. You've met someone, he doesn't speak your languages, you
doesn't speak his languages. How are you going to find out if he's
programmer, barber, or president of some banana republic? You have no
means.
I assure you, there're lots of programmers who speak only those
languages they speak outside of programming. There're those, who speak
only one language, which they speak from birth. (personal experience)
10 years I'd studied French at school; I know for sure there're 10
verbs that are in Passe Compose conjugated with a verb "aller"(?) and
others are with a verb "etre" (spelling is incorrect); And I don't know
this list; And I didn't know ever. After 10 years. And what is even
more surprising there're those who teach English and don't speak either.
Or any other language. I've met those.
And there're lots of them. Once I've spotted a message, with a
statement I remember up today: "NTU KPI -- 11 thousand cretins yearly"
(I can't get that message, google fails even to find phrases that I've
seen yesterday). I don't think them are 11 thousands, they all are
cretins, and that they are even cretins. That's a panic. We just
believe in some "famous" high-quality education. It wasn't even
mere-quality ever. But it easier to believe, then facing truth.
Look, there's a culture, where learning is suspicious. Where being
smart (not even brilliant) is an insult. We just get used to it.
But then, in case your statement would be based on quote, that would be
problem with a source. But that conclusion is yours. How you've
managed to get that idea?
I've thougt a lot. The only way I've found is based on statistical
observation that almost all (maybe without "almost") those you know, who
fit the definition, speak English (they don't have "basic grasp", they
really fluently speak). And then you expand that observation over whole
Universe. Doesn't that seem to be insane?
It's not.
I just get used to those arguments for sake of argument itself. Almost
every such argument end with the statement: "Eric! Shut up! Do what I've
said!" (BTW, it wasn't expressed this way ever.)
I give up. I have nothing to learn on this thread any more.

Your 'job' is to produce reports. So you thought you would troll here
for what, before you actually read anything about it?
I have no idea what you are talking about.

I don't think you have to worry about "bleeding-edge" for quite a long
time. Try reading books on basic regular expressions first.

^^^^^^^^^^^^^^
Rediculous. Look behind not digit and matching 1 to 3 digits
will always match any 2 digits not preceded by a digit.
So .456789053433 will always match $^N < 255 in a code conditional.

Look before you leap. The enhanced regex features are experimental and
complex in nature and offer extended pattern matching and are peculiar
to Perl for now. Perl has at large competitors in the regex market and it
won't be second to no one. However, there is a common denominator that is
the 'least', of all the suppliers out there.
For that reason, any extension (including simple non-capture grouping) is not portable
in the sense it can be cut and pasted to other software that knows regex.
There are many issues, buy you should learn the basics first instead of worrying
about 'experimental' verbage in documentation. There is no standard beyond the basics
yet. If you can't solve your problem with basic regex form first, you won't know
what to do with advanced, language/lib specific features.

And somebody else has corrected the error (which I think was a simple
typo) in the mean time.

You'll see the same phenomenon in any Usenet discussion: Somebody posts
a correct answer, but somebody else claims that it's wrong. Or somebody
posts a wrong answer and somebody else agrees that it's correct.
Sure, in Usenet you can see who made which comment and if you are in a
group long enough you get a feeling who you can trust, but that even the
most knowledgable make a mistake once in a while and even the dumbest
gets it right sometimes, so you'll still have to think for yourself.
OTOH, in a long Usenet discussion it's sometimes hard to track who said
what and what the real answer is. So I think the concept of
stackoverflow (especially the ability to edit existing answers) is very
promising for a question-and-answers service (which Usenet isn't
primarily).
> I suggest people steer clear of this kind of misinformation site.
I notice that Brian's answer has 6 votes and the answer you critizised
has only 3 votes.
