	Ancient history... Many moons ago, most Usenet servers expired posts on
some regular schedule (text groups may have gone a month to a year
depending on traffic; some of the heavier binary image groups expired in
less than three days -- miss a day and you might really miss a day worth of
traffic).

	Then came Google with their "archive for the ages"... No chance to have
the world forget things one had posted... Shortly thereafter the extension
header x-noarchive was implemented. I chose to have my client embed that
header.

If I had to ever programme in Assembler I would want to keep it to the absolute, absolute minimum. Dare I ask you to recommended some learning materials?

	Unfortunately, it tends to be specific to the processor chip -- I'm
presently going through a book on the ARM Cortex-M (and while the R in ARM
started life as RISC, it looks like CISC instruction set compared to my
college mainframe in the 70s); I have a book a few books on PIC chips lying
around, and maybe one on AVR).

	I don't even want to think about modern CISC processors. The old
Blacksburg "Bug" books are obsolete if one could find them...

	However, if you really need responsive device drivers, you'll probably
end up in assembly at some stage; there are things that not even low-level
C allows easy access to...
