I have held in my hands the BSTJ issue with "the" Shannon Paper.

I hope Rice University still has its copy.

Per wikipedia:

"In 1948, the promised memorandum appeared as "A Mathematical Theory of 
Communication", an article in two parts in the July and October issues of the 
Bell System Technical Journal."

And, no, I didn't understand one bit of it -- other than the significance.
(Especially the part about "this is why I am going to have a job.")

"Planning" may assume facts not in evidence :-)

I was near enough to a piece of machinery to be told "point to

By that time I was well-experienced with my high school machine (a Bendix G-15,

The 960B is the only computer I ever walked away from and said "I can't do 
this".  This was mostly, but not entirely, due to the Silent 700 and its 
cassette tapes.

It took 20 minutes to load the loader, and, then, if I got that right, 20 
minutes to load the editor, and *then* I could start doing work.

As long as "work" was not "hit tab".

Because then the editor would crash, and you were back to the beginning.

Even in my younger and smarter days my error rate was more than one every 45 
minutes.

I had to BS my way through the coursework that required that machine.

Apparently you don't understand that "maintaining software requires

If you want to make changes to e.g. a kernel then there are things that

And if you *don't* make changes to your kernel, then you fall behind on:
performance, running on newer systems (think ACPI, EFI), multi-core,
NUMA, and so on and so forth.  You simply become irrelevant for anything
that people can *actually buy new*.

There has not been a free option for seveal years.  I switched to the

I was just investigating free alternatives myself earlier today.  (I

I currently use the free he.net ivp6 tunnel so I may already be set up

Most of the articles on the web mention:

  Dynu, afraid.org, Duck DNS, and No-IP

Before anyone scoffs, warehouse space is expensive.  It drove the
company I was last working for to move out of Austin.  Their business
was similar but more oriented towards e.g. getting newer machines,
disk-wiping them, and selling on eBay.  The selling prices are/were
competitive and so the margins were much lower.  Thus, they couldn't
afford to keep things around for years.

Two different business models.

I really wish I still had one technical magazine that came out during
the late 70s/early 80s.  (I don't remember which one it was, anymore.)
It was devoted to keeping you up with the latest chip/minicomputer
technology.

It contained a very serious editorial about "what are we going to use to
replace CMOS" now that the > 10MHz chips were starting to be avialable.
"Clearly" there was no way to push the technology past that: it was simply
impossible due to heat dissipation -- the chips were going to burn up.

It was an open-ended question; clearly neither ECL nor TTL were going to
fit the bill.  (Hey, at least the author got _that_ part correct.)

Oh and while we're skewering early CMOS chips, they were grossly sensitive
to static.  The company I was working for during the summers was buying
these $40 4-digit LED things with a CMOS driver and if you even looked
at it wrong you could watch the chip swell up and bake underneath its
protective plastic.

This was not not very amusing to management.

I'll bet I still have one in a box somewhere.
