... f articles from
people who post in more than one newsgroup, such as cascaders, since
an article's newsgroup name is always in the header.
If you just want to block messages with a subject line about
cascades, you could try:
/foo/:j
To kill anything that is a followup to any article, use this
pattern:
/Subject: *Re:/:j
When done writing lines for each phrase to screen, exit the text
editor as you normally would, and you'll be put back in rn.
One word of caution: go easy on the global killfile. An
extensive global killfile, or one that makes frequent use of the a:
modifier can dramatically slow down rn, since the system will now have
to look at every single word in every single message in all the
newsgroups you want to read.
If there's a particular person whose posts you never want to see
again, first find his or her address (which will be in the "from:" line
of his postings) and then write a line in your killfile like this: new york design
/From: *name@address\.all/h:j
4.3 SOME USENET HINTS
Case counts in Unix -- most of the time. Many Unix commands,
including many of those used for reading Usenet articles, are case
sensitive. arizona design Hit a d when you meant a D and either nothing will happen,
or something completely different from what you expected will happen.
So watch that case!
In nn, you can get help most of the time by typing a question mark new york design
(the exception is when you are writing your own message, because then
you are inside the text-processing program). In rn, type a lower-case h
at any prompt to get some online help.
When you're searching for a particular newsgroup, whether through
the l command in rn or with nngrep for nn, you sometimes may have to
try several keywords. For example, there is a newsgroup dedicated to
the Grateful Dead, but you'd never find it if you tried, say, l grateful
dead, because the name is rec.music.gdead. In general, try the smallest
possible part of the word or discussion you're looking for, for example,
use "trek" to find newsgroups about "Star Trek." If one word doesn't
produce anything, try another.
4.4 THE BRAIN-TUMOR BOY, THE MODEM TAX AND THE CHAIN LETTER
Like the rest of the world, Usenet has its share of urban legends
and questionable activities. There are three in particular that plague
the network. Spend more than, oh, 15 minutes within Usenet and you're
sure to run into the Brain Tumor Boy, the plot by the evil FCC to tax
your modem and Dave Rhode's miracle cure for poverty. For the record,
here's the story on all of them:
There once was a seven-year-old boy in England named Craig
Shergold who was diagnosed with a seemingly incurable brain tumor. As
he lay dying, he wished only to have friends best web design audubon send him postcards.
The
local newspapers got a hold of the tear-jerking story. Soon, the boy's
wish had changed: he now wanted to get into the Guinness Book of World
Records for the largest postcard collection. Word spread around the
world. People by the millions sent him postcards.
Miraculously, the boy lived. An American billionaire even flew
him to the U.S. for surgery to remove what remained of the tumor. And
his wish succeeded beyond his wildest dreams -- he made the Guinness
Book of World Records.
But with Craig now well into web design glasgow his teens, his dream has turned into
a nightmare for the post office in the small town outside London where
he lives. Like Craig himself, his request for cards just refuses to
die, inundating the post office with millions of cards every year.
Just when it seems like the flow is slowing, along comes somebody else
who starts up a whole new slew of requests for people new york design to send Craig
post cards (or greeting cards or business cards -- Craig letters have
truly taken on a life of their own and begun to mutate). Even Dear Abby
has been powerless to make it stop!
What does any of this have to do with the Net? The Craig letter
seems to pop up on Usenet as often as it does on cork boards at major
corporations. No matter how many times somebody like Gene Spafford
posts periodic messages to ignore them or spend your money on something
more sensible (a donation to the local Red Cross, say), somebody
manages to post a letter asking readers to send cards to poor little
Craig.
Don't send any cards to the Federal Communications Commission,
either.
In 1987, the FCC considered removing a tax break it had granted
CompuServe and other large commercial computer networks for use of the
national phone system. The FCC quickly reconsidered after alarmed users
of bulletin-board systems bombarded it with complaints about this "modem
tax."
Now, every couple of months, somebody posts an "urgent" message
warning Net users that the FCC is about to impose a modem tax. This is
NOT true. The way you can tell if you're dealing with the hoax story
is simple: it ALWAYS mentions an incident in which a talk-show host on
KGO radio in San Francisco becomes outraged on the air when he reads a
story about the tax in the New York Times.
Another way to tell it's not true is that it never mentions a
specific FCC docket number or closing new york design date for comments.
Save that letter to your congressman for something else.
Sooner or later, you're going to run into a message titled "Make
Money Fast." It's your basic chain letter. The Usenet version is always
about some guy named Dave Rhodes who was on the verge of death, or
something, when he discovered a perfectly legal way to make tons of money
-- by posting a chain letter on computer systems around the world. Yeah,
right.
There are .sigs and there are .sigs. Many people put only bare-bones
information in their .sig files -- their names and e-mail addresses,
perhaps new york design their phone numbers. Others add a quotation they think is funny or
profound and a disclaimer that their views are not those of their employer.
Still others add some ASCII-art graphics. And then there are
those who go totally berserk, posting huge creations with multiple quotes,
hideous ASCII "barfics" and more e-mail addresses than anybody could
humanly need.
College freshmen unleashed on the Net seem to excel at
these.
Usenet's international reach raises interesting legal questions that
have yet to be fully resolved. Can a discussion or posting that is legal
in one country be transmitted to a country where it is against the law?
Does the posting even become illegal when it reaches the border? And
what if that country is the only path to a third country where the
message is legal as well? Several foreign web design glasgow colleges and other
institutions have cut off feeds of certain newsgroups where Americans
post what is, in the U.S., perfectly legal discussions of drugs or
alternative sexual practices. Even in the U.S., some universities have
discontinued certain newsgroups their administrators find offensive,
again, usually in the alt. hierarchy.
An interesting example of this sort of question happened in 1993,
when a Canadian court issued a gag order on Canadian reporters covering a
particularly controversial murder case. Americans, not bound by the gag
order, began posting accounts of the trial -- which any Canadian with a
Net account could promptly read.
4.7 USENET HISTORY
In the late 1970s, Unix developers came up with a new feature: a
system to allow Unix computers to exchange data over phone lines.
In 1979, two graduate students at Duke University in North
Carolina, Tom Truscott and Jim Ellis, came up with the idea of using
this system, known as UUCP (for Unix-to-Unix CoPy), to distribute
information of interest to people in the Unix community. Along with
Steve Bellovin, a graduate student at the University of North Carolina
and Steve Daniel, they wrote conferencing software and linked together
computers at Duke and UNC.
Word quickly spread and by 1981, web design development uk a graduate student at Berkeley,
Mark Horton and a nearby high school student, Matt Glickman, had
released a new version that added more features and was able to handle
larger volumes of postings -- the original North Carolina program was
meant for only a few articles in a newsgroup each day.
Today, Usenet connects tens of thousands of sites around the world,
from mainframes to Amigas. With more than 3,000 newsgroups and untold
thousands of readers, it is perhaps the world's largest c ... |
