Not possible. As JavaScript runs client side, any such attempt is easily
bypassable.

Put the password protection on all the pages, and make it real password
protection.

Javascript is not used for any real security.

Forum4designers appear to be passing off Usenet as their own work. I suggest
avoiding them. This is news://comp.lang.javascript.

Can't be done with client-side script.

I had no problems in any browser. Nothing asked for a password. A bunch

You're using apache.
Use .htaccess.
Google it. That's OT here.

Apart from the misrepresentati on of the content of the
www.forum4designers.com site as a service that they are providing rather
than admitting that it all originates in Usenet newsgroups,
www.forum4designers.com is also a very bad place to read
comp.lang.javas cript as they are re-formatting the content of the
newsgroup posts and loosing all of the indentation in the presented
code.

Generally the regular posters to this group put quite a bit of effort
into presenting well-formatted code, indented to make its structure
apparent to the reader. They also (seemingly universally) promote the
consistent indentation of code blocks as a "best practice" in code
authoring.

But the way that comp.lang.javas cript is being presented on the
www.forum4designers.com site makes it look like starting each line of
code at the left margin is common, acceptable and normal practice. (Or
givies the impression that all the code presented on the group was
authored by amateurs who don't understand haw code should be written.)

I am also not very happy to see:-

I like the way that alt.html and alt.html.critiq ue appear to have
decided to react. I wonder how long they will keep it up. :)

I wonder if I can guess roughly where they are located ... it appears to
be misuse of resources belonging to others, combined with breach of
copyright law, both local and international.

Partial ostracism is probably the best we can do, unless complaining to
giganews is effective.

By that I mean not answering questions posted via that route, and
pointing out errors in replies but not giving corrected versions.

Breaches of c.l.j agreed etiquette, disregarding Uno Hoo's weirdnesses,
should however be pointed out on a regular basis.

Perhaps there is room in the c.l.j FAQ for a pointer to one or two
suitable news servers / services? Since the FAQ can be found by a naive
Web user Googling for a specific answer, ISTM right to indicate,
directly or indirectly, how the newsgroup should normally be accessed -
both from a real news-server, and from an honest, standards-compliant
Web service.

Stripping indentation is almost completely harmless in javascript,
except where it is intended that it should be read by persons. But in
plain text, which can have tables laid out by indentation, it can easily
corrupt meaning. And News is a plain text medium.

Nopefully until they either go away or they openly acknowledge that they are
merely a web base newsreader (*).

(*) Properly constructed web based newsreaders are IMNO a good thing,
google.groups in particular. Not everybody has access to a newsreader
(libraries, internet kiosks etc).

If everyone put a line in their sigs stating specifically that teh post
a) has nothing to do with that forum site, and b) permission to archive
teh post is specifically denied to that web site, do you think there
might be grounds for a lawsuit is they then persistently ignored the
notice?

At the least, it might make people on the forum notice something is up.

I am not a lawyer but... well, - but nothing - I don't know. Legal
action costs money and takes time though, so do you have enough of
either going spare in order to find out?

(class action anyone?)

groups.google.c om provide facilities for posting to Usenet (at least the
groups they archive) from a web browser. They require you provide them
with a working e-mail address, as they you activate your account by
responding to an e-mail that they send you after your application. I
could mention that possibility at the end on Section 2.11, which is
about the archives at google.groups.c om, or in Section 2.3.

Yes, the interpreter doesn't care much about whitespace so indentation
does not effect execution (much as it doesn't effect C++ or Java) but
posted code is certainly intended to be understood by humans, and
usually formatted with that in mind.

We see more code than tables but they will be subject to the same
problem. Along with asci art diagrams and the like.

I think so, if we are satisfied that Google-news is decently standards-
compliant.

If one needs to use Web for news, at least one should use a properly-
operating system.

Yes. My point was that, while space-stripping is annoying in javascript
and, say, Pascal/Delphi/C etc., it is destructive in such as FORTRAN and
that language which uses indentation instead of {...} / BEGIN...END; and
it can be destructive in plain text, which is the chief News language.

Agreed; they have their place.

But, for those who can use a newsreader, we should make it reasonably
clear that the best experience is obtained with properly-designed well-
written standards-compliant news software that has local storage; or,
failing that, OE.
