There are a couple of real truths in the midst of this thread, but...
First I want to thank all of the folk who contributed to the
construction of this latest version. I've watched bug fixes, and doc
editing as we approached the release and several have done the heavy
lifting. Thanks. Then the final tasks of putting it all together in a
form that we can use is real tedious. Thanks again.
Now for the first truth -- both parts of it. I switched to my old 6.06
compile box this morning, (For those of you who are curious it's a KVM
Switch) hit the upgrade available icon and there was EMC2 1.2.2.6
waiting. A couple of clicks and my password and it's mine.
1a -- A running Ubuntu EMC2 is essential to understanding the
automatic release functions of the system. A running EMC2 is
the lab portion of the College course EMC2-101. Yes you can
take the class without the lab but I wouldn't recommend it.
1b -- Connecting that PC to the web makes the Linux/Ubuntu/EMC2
world a lot easier to comprehend.
I'm NOT saying here that I've given up my status as a computer explorer
for the comfort of a computer settler. I still play with patching and
compiling, and watching stuff fall face down into the mud, but what I am
saying is that an EMC2 install from the released CD is a good thing to
have laying around. It is my baseline these days. For those
comfortable with experimental design, it's my control group.
And that leads me to the second truth. "Of the writing of books, there
is no end." We have books and books are good. Big John has recently
taken the lead and has been editing these books. Much of the result can
be seen in the docs that travel with the new release.
I'm told that the number of authors is rapidly approaching the number of
readers. Which means that; we sell one copy, there are prolific readers
someplace, or there are collectors of books out there.
The fact is that a book about EMC2 will never be an attention grabber
like a Ludlum thriller. An EMC2 manual is a reference document. A
comment like RTFM really is an insult when there are more than 400 pages
of formal stuff out there and thousands of pages of informal but
valuable information. I'm pleased that no one made that (RTFM)
suggestion here.
Long ago we had reference librarians who could find almost anything you
needed. These days IRC and this list tend to serve some of that purpose
and asking there or here tends to get a link but then there's asking and
there's asking. It always seemed to me that those said something like,
"I tried this reference and that but I need some help," got a lot
further than those who haughty folk who looked down on and lam-blasted
the librarian as the stupid keeper of way old books.
