Notes

notes on using Ubuntu 9.10 on the Dell Zino.
gscan2pdf makes it easy to scan complete documents (even if the scanner does not support 2-sided scanning).

simplify support for utf8 on mysql: adding the following to my.cnf will ensure that all connections use utf8. See this page for more info.

[mysqld]
init_connect='SET collation_connection = utf8_general_ci'
init_connect='SET NAMES utf8'
default-character-set=utf8
character-set-server=utf8
collation-server=utf8_general_ci
skip-character-set-client-handshake

(Exuberant) ctags for java/C++:

# -R: recurse
# --extra=+q: class support
ctags -R --extra=+q .

See also global for even more functionality:

apt-get install global
cd /root/of/source/tree
gtags # creates GPATH  GRTAGS  GSYMS  GTAGS files
cd /root/of/source/tree/anywhere/in/the/tree
global -x functionName # shows where defined
global -rx functionName # shows where referenced
vim $(global functionName)
vim $(global -r functionName)
:GtagsCursor # brings you to definition or reference of current token
:cn # next reference/definition
:h quickfix # help with quickfix list, which is output format of GtagsCursor
:ccl # quit quickfix list

See gtags.vim for more info on vim usage.

For handouts from slides: use pdfnup from the pdfjam package. On gentoo: emerge pdfjam.
Gentoo linux 2005.1 on a Dell Latitude C600.
Converting eps files to pdf (e.g. for inclusion in pdflatex input): ps2pdf won't do because of bounding box problems. The script epstopdf (not eps2pdf!) does the job (sets pdf media info based on bounding box in eps comments). Comes with tetex. Another interesting pdf tool: pdfjam which includes a script pdfnup to print multiple pages from the original document on one page.
Nice tool for manipulating pdf files: pdftk (available in portage).
Activating babel: (as root)
```
     texconfig hyphen latex
     
```
Getting simple accents to show correctly on the screen in a US setup:
```
	export LC_CTYPE=fr_FR
	
```
Typing accented letters using vim on a US keyboard:
```
	:set kmp=accents
	
```
then type e.g. 'e for é etc.
Converting latex to microsoft word files:
1. Use latex2rtf to convert document.tex to document.rtf (I used the options -C latin1 -i dutch). Latex2rtf (here is a recent tarball) is trivial to install and does not seem to depend on anything non-basic:
```
      tar zxf latex2rtf-1.9.14.tar.gz
      cd latex2rtf-1.9.14
      make && make install
      
```
2. Load document.rtf in openoffice and save as "word" document.
3. Complain to whoever forces you to use such a format.
Installing a personal spamassassin on a system where you use procmail as delivery agent.
Installing spamassassin "globally" on a system using postfix.
To convert weird windoze e-mail attachments: "man tnef" (in gentoo: emerge tnef). See also man uudeview (in gentoo: emerge uudeview).
Activating dutch hyphenation for the latex babel package (tetex distribution):
1. Edit /usr/share/texmf/tex/generic/config/language.dat (or whereever the tex language.dat file is) and uncomment the line pertaining to dutch.
2. As root, run fmtutil --all to regenerate all formats.

Giving automatic arguments to aclocal (e.g. from autoreconf): set ACLOCAL_AMFLAGS in top level Makefile.am or define
```
export ACLOCAL="aclocal -I /bla/bla"
```
Docbook notes.
Using vim on XML files:
- Set folding method to ``syntax''
```
	 :set foldmethod=syntax
	 
```
- Open fold: zo, close fold: zc, more.
Installing a new .sty (style) file, e.g. in /usr/share/texmf/tex/latex/misc/: don't forget to run
```
	texhash
  
```
(as root, obviously).

Blacklisting a site in procmailrc:

	:0:
	* $(FROM) .*@obnoxious.com
	EXITCODE = 67 # will bounce as "no such user"
	/dev/null

Other exit codes can be found in sysexits.h. See also.

Ensuring that "make distcheck" does not fail on directives of the form
```
#include <package/file.h>
```
in header or other files: add @srcdir@/.. to the include directories in Makefile.am, as in the following example.
```
INCLUDES = -I@srcdir@/.. @CXXINCLUDES@
```

Calling doxygen's installdox at installation time from Makefile.am (automake 1.7.3): using

	$(DESTDIR)$(pkgdatadir)/html

will ensure that "make distcheck" does not balk on running installdox. Here is a complete doc/Makefile.am.

nobase_dist_pkgdata_DATA = $(shell cd $(srcdir); ls html/* latex/* )
# @doxyurl@ is set in configure
doxyurl = @doxyurl@
install-exec-local: # create e.g. /usr/local/share/@PACKAGE@/download
        $(mkinstalldirs) $(pkgdatadir)/download
				
install-data-hook: # ensures this is done after install-data
	(cd $(DESTDIR)$(pkgdatadir)/html; \
	@perl@ installdox -l "dvutil.tags@$(doxyurl)dvutil/html" )

Postfix

Use
- postconf to see configuration parameters.
- postfix reload after update *.cf.
- postmap to remake *.db
Initializing mysql on a slackware distribution

The command sequence to initialize the mysql database and start the server, as stated in the manual, does not work.
You should also change the ownership of /var/lib/mysql after initializing the database and before starting the server.
```
     /usr/bin/mysql_install_db # initialize tables
     cd /var/lib/mysql; chown -R mysql.mysql . # change ownership of database files
     /usr/bin/safe_mysqld & # start server
     mysqladmin -u root password 'newpassword' # set root password
     
```
Errors in (output of) \ref{} processing for table and figure labels in latex

Make sure the \label{} is part of the caption, as in
```
     \begin{table}
     ..
     \caption{\label{my-table}My Table}
     \end{table}
     
```
sudo over ssh
X connection does not work when doing su(do) on an ssh connection. Fix: set DISPLAY explicitly.
export DISPLAY=client-ip:0 su ..
