Q: Does anyone ohave any experience with GPIB interface programing under linux ?
A:(By Nicolas Delerue)
Message 16
Yes, most of my experimental measurements are done using GPIB from my own laptop computer (and the other are done using CAMAC and VME). I have written the code in C.
Have a look at http://acfahep.kek.jp/subg/ir/feather/beamTests/code/talk.c.
As you can see it is adapted from National Instruments code.
It is the code I use to communicate with the GPIB device. Then you have to write the instructions you send to your device but those are device-dependant. I have some examples for a HP tektronix digital scope (5Gs/s, 1GHz bw), pulse generator (tektronix), timer and other devices...
Usually, these instructions are in manuals (japanese only) but it is often easy to gess what they do from their name (in english).
These devices are connected from a GPIB to ethernet converter (as I can not use PCI card on my laptop). The advantage of this device is that I can check the status of my scope from anywhere at KEK (I can not from outside KEK as there is a firewall)...

Q: I want to edit Japanese documents under linux. How shall I do?

Emacs 21.3.1 (and some earlier versions) basically include the former mule. So, basically, any recent versions of Linux will provide you with the ability to read/write e-mail/documents in Japanese without any particular setup (that's what I use everyday). You will need to select FreeWnn or Canna to provide you with kanji writing. For integrated dictionary, you can also combine edict in emacs (see below).
Browsing Japanese pages isn't an issue if you use mozilla/firebird/firefox. And of course other browsers do just fine.
Note on edict with emacs:
Here are some (hopefully useful) lines (to be added to your .emacs file) to get edict to translate your text. Using esc-* will give you English to Japanese translation. esc-_ gives you Japanese to English translation. You need to select the word beforehands of course. Don't forget to update the locations of your edict.elc file as well as those of your dictionaries (distributed with edict).

;;; japanese: edict
; finding the macros elisp
(setq load-path
(append (list "/usr/share/emacs21/site-lisp/edict-el")

;; japanese: edict.el
(setq edict-dictionaries
'(("/usr/share/edict/edict" . euc-jp)
("/usr/share/edict/compdic" . euc-jp)
("/usr/share/edict/jddict" . euc-jp)))

;; Load edict.el (faster than using autoloads)
(load-library "edict")
;; Keyboard shortcut: 'M-_' to translate from japanese to english
(global-set-key "\e_" 'edict-search-kanji)

;; Keyboard shortcut: 'M-*' to translate from english to japanese
(global-set-key "\e*" 'edict-search-english)

Q: How to set-up encrypted signature/mail encryption in a mailer
A: (adapted from Nick Hasting's reply)
Message 37
It was a while ago, but I think I just followed the "Gnu Privacy Guard Mini Howto" http://webber.dewinter.com/gnupg_howto/english/GPGMiniHowto.html.
This tells the basics of how to generate a key, upload it to a keyserver, sign and encrypt etc. Very useful to encrypt files when you don't trust everyone on your machine (especially if they have root).
The default mutt configuration (/etc/Muttrc) is pretty sane, the only thing I added to my .muttrc was:
set pgp_getkeys_command="gpg --recv-keys %r > /dev/null 2>&1"
this just makes mutt automatically download and check keys.
To sign or encrypt mail in mutt you then need to hit "p" in the compose dialogue.
Hmm... just stumbled across: "Mutt-i, GnuPG and PGP Howto" http://www.tldp.org/HOWTO/Mutt-GnuPG-PGP-HOWTO.html, may be of use.
Pine users should look at http://www.defcon1.org/About_Us/News/Upcoming_Articles/PGP-Pine/pgp-pine.html.
