recent gpg-agents are compatible with ssh. I use gpg-agent for both
without problems.

If I understand you correctly use agent forwarding. It's a sshd option.

You can find ruby-mode in the misc/ directory of the Ruby source code
(www.ruby-lang.org).

Ruby is also supported in CEDET (cedet.sf.net) for use in ECB
(ecb.sf.net) though I do not know how much of the smart completion, or
other features from CEDET work.

Thanks, this might be, indeed, what I want, though I want to
understand better why the ssh man page says that agent forwarding
should be enabled with caution. How does agent forwarding compare
with running a second agent on the remote host?

Thanks for this. I'll try it. But I am not so sure...

I use emacs for quite different purposes. I like to have the
customizations of these separately maintained.  As a programmer I
appreciate internal cleanliness more than external sugar-coating :-)

However this forces me to keep my c-mode and python and org and ecb
and god-knows-what-else customizations all together -- which I dont
like.

The problem as I see it is that the specification of initialization
in .emacs is given imperatively whereas it could be more declarative
and event-driven.

Assuming emacs is to .emacs as linux is to init, a possible
alternative that illustrates would be upstart -- see
https://wiki.ubuntu.com/ReplacementInit#head-4263a0dc03fdf9b46c2004f3e63d8033990db10a

Theres a good ruby/rails-oriented emacs demo at http://platypope.org/yada/emacs-demo/

I don't really know why it is like it is, but it is. Anyway, add to
~/.emacs:

(eval-after-load "f90"
  '(progn
     (setq f90-font-lock-keywords-3
      (append f90-font-lock-keywords-2
          (list
           f90-keywords-level-3-re
           f90-operators-re
           (list f90-procedures-re '(1 font-lock-builtin-face keep))
           "\\<real\\>"))
      f90-font-lock-keywords-4 (append f90-font-lock-keywords-3
          (list f90-hpf-keywords-re)))))

In case you want to change the colour, you can start with C-u C-x =  
on a character in the unwanted face (font and colour). A *Help*  
buffer opens, allowing you to customise the settings in the  
"paragraph" where it describes the text properties.

In your case it will fail, because apparently different sorts of key  
words are mixed. So you would change the face for all of them again,  
for the whole set or "mixed" case.

Bookmarks in non-file buffers?

Is there a way to save the current position (by placing a bookmark or
in any other way) in a buffer that is not associated with a file?
Namely, I'm interested in w3m buffers, pdftotext output and text files
extracted from zip archives in zip-archive mode. Of course, besides
the text position (line number) such bookmarks should contain the
information on how the text was produced.

http://www.emacswiki.org/cgi-bin/wiki/Icicles_-_Multiple_Regions should help,
but no info is saved about "how the text was produced".
