What are they? How could they be used in computer technology?

HTML, what is it? Something you don't post to newsgroups in, along with
overly large sig lines.

He's using Gmail. That explains it. I have now added Gmail and
anything Google to my Usenet filters like others have recommended here.

The posts look goofy, because the charset is "Big5". I don't see
any signs of HTML, just an inappropriate charset for a mainly
English newsgroup.

There is a definition of canonical here, for what it is worth.
Canonical form is "written in the usual way"

That site explained what "canonical" is. Any beginner's guide to
canonical numbers?

Canonical Name (CNAME) Records
http://www.zoomtown.net/

http://www.webopedia.com/TERM/C/canonical.html

A canonical number night be something like 192.168.0.1
where the order is most significant to least significant.
In a PTR record, apparently they reverse that order,
and such a reversal would be a "non-canonical" form.
In this usage, the order of the IP address is reversed.

You won't really know what the canonical or "usual way" is,
unless you are a practitioner in some specialty. Only
then would you become familiar with what is the "usual way"
of doing things.

A place for confusion, would be in the writing of the
date. There are a number of practices in the world, for
the order to put the Month, Day, and Year. In that case,
there would be no "canonical" date specification, as people
choose to disagree on the order. (In fact, on the last
three lots of personal cheques I got from the bank, in
each case, the date field definitions have been changed.)
