This article was written
in response to a recent post in the General Discussion Forum
concerning downloading of messages from Remarq. In this article,
I hope to highlight what Usenet is, its differences from web
browsing, how to connect to it, and where to find big breasts
on it! I hope it will enlighten the Usenet uninitiated, but
also convey a greater understanding of how it works to frequent
users.
Sites such as Remarq
(there are others, but Remarq gets referred to most often
at the BEA) perform an admirable service for those
who are unable to access the Usenet by proper means. However,
because it is accessed over via the Web, it in no way makes
an adequate tool for downloading large quantities of images
that are posted to newsgroups. Let me explain why…
| INTERNET,
THE WEB, AND USENET |
“The first thing to understand
about Usenet is that it is widely misunderstood.”
- Chip Salzenberg
During the late 80’s
and into the 90’s, the World Wide Web has become the norm
for traversing the internet, mainly because of the ease-of-use
of HyperText Transfer Protocol (HTTP), and the lovely, flashy,
graphics-laden web pages that browsers can display. When you
wish to view a page on a web site (say at the BEA,
for instance), your computer will ‘talk’ to your ISP’s*
server,
this server will then determine the ‘IP’ address where the
web page is stored, and work out a route over other internet
servers (known as ‘nodes’) to the server that stores the requested
page. Once the target server has received notice that information
is required, it will process all the necessary data and transfer
it back across the nodes to your ISP’s server, and ultimately
onto your computer.
As you may have guessed,
this process is fraught with areas where the process can be
slowed down. First, your ISP could be busy: the requesting
of information, determination of the route to take, and reception
of information could be slowed. Next, you have no idea of
the quantity of traffic over each of the nodes, as these will
usually be ISPs themselves. Last and possibly most important
is the quantity of net traffic at the target site – if it's
very popular (as Remarq is), then it's going to need a very
fast connection to the web to keep speeds up, and some damned
hefty servers to process all the transactions.
(*Note: When I refer
to ISPs, I predominantly mean commercial internet providers,
but not exclusively. I also mean other internet providers
such as Educational, Governmental faculties, etc., that use
internet connections.)
When you consider that
there are over 40,000 publicly available newsgroups on the
Internet (of which Remarq captures a fair chunk), and that
many of them receive over 1000 messages per day (with some
for the more popular groups such as alt.mag.playboy, it's
not uncommon to find 4000+ posts a day), you can see that
any server has its work cut out just receiving it all. When
you add the fact that web-based news browsers have to cope
with huge number of requests from all 'round the world, then
you can understand that there is a fairly large potential
for slowdowns.
Internet News, or Usenet,
inherently differs from Web browsing, and many would say that
it was the first freely accessible area of the Internet. In
many ways, Usenet is more akin to the e-mail account that
you may have received from your ISP. When you post a message
with a POP mail account, it gets uploaded to your ISP’s POP
mail server, which identifies the recipient’s server from
the address, traverses the Internet (across nodes if necessary),
and drops the message into the recipient's ‘In-Tray’, ready
for downloading.
Similarly each ISP that
is Usenet-enabled carries a Network News Transport Protocol
(NNTP) server that handles all the news activity. When you
create a news post, the message is uploaded to your news server,
and then out from there. The difference is that once it lands
on your news server (the original node), it propagates in
all available directions to every Usenet node around the
world. This means that when
you download a post from, say, alt
.binaries .pictures .erotica .breasts,
you are actually downloading it locally from your ISP’s news
server. Naturally, this is going to be far faster than traversing
the whole of the internet via a web browser.
Examples
of the quantity of Usenet traffic can be found here.
comp
- topics of interest to computer users of all categories
misc - groups addressing themes
not easily classified into any other headings
sci - discussions relating to
research in or application of the established sciences
soc - groups primarily addressing
social issues and socialising
talk - largely debate-oriented
news - concerned with the Usenet
network itself
rec - oriented towards hobbies
and recreation
As
the Internet --and thus Usenet-- has grown, more root hierarchies
have been added, and the one in which most of you boob hounds
will be interested is the alt (alternative and anarchical)
groups hierarchy. The alt groups hierarchy has grown rapidly
as the Internet gradually frees itself from Educational /
Governmental organizations and penetrates the mainstream,
yet it contains the most taboo areas of the Internet. Anything
from Sex to The Simpsons is covered in the alt groups.
