Calmar's Latex tips

• pdf (e.g. make smaller to a5) and keep orientation: gs -o out.pdf -sDEVICE=pdfwrite -dAutoRotatePages=/None -sPAPERSIZE=a5 -dPDFFitPage -dCompatibilityLevel=1.4 in.pdf. 'pdfunite' for mergin.
• very good tutorial for beginners
• reference of latex commands: necause
• Fine Latex Ref-Card : latexsheet.pdf (local copy)
• (German) Rechnungen mit Latex : rechnung.sty  (referenz) use 3.10; sudo texhash; sudo update-texmf; to find it
• When dvipdf cuts the top of a letter: `sudo texconfig dvips paper a4' or similar might help (/etc.../config.ps).
• `latexmk' is a very nice tool too. `latexmk -[cC]' for cleaning up. `latexmk -pdf' generates pdf's for all .tex files in the directory. `latexmk -pdf -pvc' checks a file for an update, and creates a new .pdf instantly. E.g. after a :w in vim. then :!xpdf %:r.pdf for watching it inside vim.

• Ref-Cards:

  http://www.refcards.com
  (--> once printed, laminated and kept in the near of the computer (at the side of the monitor maybe), a great help.)

• Recover deleted files on ext3/4:

  umount partition #(may reboot and login as root etc)
  mkdir recover-dir #(make directory for recorverd files)
  extundelete /dev/partition  --restore-all -o recover-dir
  

• • initialysing mysql: sudo mysql_install_db
  • may set your password in /etc/mysql/my.cnf
    and/or set password with: /usr/bin/mysqladmin -u root password 'secret'
  • backup: mysqldump --opt -Q -u dbusername -p [databasename] > /path/to/backupname.sql
  • restore: mysql -u dbusername -p [databasename] < /path/to/backupname.sql

• Make postfix relaying messages:

  postconf -e 'relayhost = smtp.example.com'
  postconf -e 'smtp_sasl_auth_enable = yes'
  postconf -e 'smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd'
  postconf -e 'smtp_sasl_security_options ='
  postconf -e 'smtp_sasl_security_options = noanonymous'
  postconf -e 'smtp_use_tls = yes'
  
  echo "smtp.example.com   someuser:howtoforge" > /etc/postfix/sasl_passwd 
  chown root:root /etc/postfix/sasl_passwd
  chmod 600 /etc/postfix/sasl_passwd
  postmap /etc/postfix/sasl_passwd  #create sasl_passwd.db
  /etc/init.d/postfix restart
  

• Mplayer (mpv now!)

  needs libasound2-dev (debian for finding alsa during ./configure)
  
  

• Apache startup:

  "Could not reliably determine the server's fully qualified domain name"
  
  »   sudo {editor} /etc/apache2/httpd.conf (open that file)
  »   ServerName localhost (add this somewhere)

• Xmodmap

  Create the default one (xmodmap -pke > .Xmodmap-tmp). Then clear all special thing at the begin. Change keycodes - and finally add the special things again (similar to xmodmap -pm) at the end.
  See: xmodmap.diff

• Nvidia Driver

  Use an according NVidia Graphic Cards Driver instead of the default kernel-one driver. It will improve your linux-system performance and speed all around!
  
  When the NVidia installer can't find header files like include/version.h, even so the sources are there (besides of that file), use the --kernel-source-path switch like:

  bash NVIDIA-Linux[...]pkg1.run --kernel-source-path=/usr/src/linux2.6.xx
  

• For some reason, I had to compile the kernel with the sound-card-code as module instead of included. So at least 'alsaconf' found it then and configured everything afterwards.
• Genoot-Install-hints:
  
  • Grub2 is a @#$%@ing mess.. "linux (hd1,msdos4)/bzkernel root=/dev/hda2
    grub2 truetype use-flag -> grub2-mkfont for creating font ...
    and in /etc/default/grub ->
    GRUB_FONT=/boot/grub/xxx/xx.pf2 - GRUB_GFXMODE=1280x1024x24 - GRUB_GFXPAYLOAD_LINUX=keep
  • Nvidia driver seperate download (on seperate kernel?) and run(install)
  • Keyboard+mouse not working in X: "emerge sys-fs/udev" + starting helped
  • Fetchmailrc: user:group -> fetchmail:fetchmail required
  • (Zic warning:) cp /usr/share/zoneinfo/Europe/Zurich /etc/localtime
  • Mutt haning while opening boxes: remove cache (rm .mail/mutt_cache/*)
  • "emerge alsamixergui" and sound was ok.
  • emerge .. ubuntu-font-family/corefont/liberation-fonts/droid/dejavu/media-fonts etc

• Crontab entries works like that:

  I'm acually using fcron.free.fr

  Minutes	Hours	DayOfMonth	MonthOfYear	DayOfWeek	command
  0-59	0-23	1-31	1-12 or jan,feb,mar..	0-6 (0=sunday) or sun,mon,tue..	(whatever)

  The commands get executed at the 'next' instance of a possible value. Possible values are (here in the case of minutes):

  *	executes every minute
  0-30,31-45,46-59	executes every minute
  0-3,30-32	executes on minutes: 0,1,2,3 and 30, 31,32
  0,1,2,3,30,31,32	executes on minutes: 0,1,2,3 and 30, 31,32
  */15	executes on minutes: 0,15,30,45
  0-59/15	executes on minutes: 0,15,30,45
  0,15,30,45	executes on minutes: 0,15,30,45

  Additonally there are some special variables:

  @reboot	on reboot	no equivalent (quite useful)
  @yearly	every new year	0 0 1 1 *
  @annually	same as @yearly	0 0 1 1 *
  @monthly	every new month	0 0 1 * *
  @weekly	every new week	0 0 * * 0
  @daily	every new day	0 0 * * *
  @hourly	every new hour	0 * * * *

  Some examples:

  30 9-17 * 1 sun,wed,sat  echo `date` >> /date.file 2>&1        
  @reboot                  /usr/bin/fetchnews 2>/dev/null 1>&2 
  */15 * * * *             /usr/sbin/fetchnews 2>/dev/null 1>&2
