das ist der refrain eines schönen mainstream-pop-songs. ich hatte mir das nicht so ganz klar zum ziel gesetzt, doch im nachhinein muss ich sagen, ich hätte es besser. alleine aufzuwachen macht den tag schon zunichte, bevor er begonnen hat.

ich hatte heute viel zeit zum überlegen. zu viel zeit fast. ich habe mir gedacht, dass wir heute einfach zuviel luxus haben. der mensch sollte eigentlich besser ums überleben kämpfen, tagein tagaus. dann hätte man gar nicht die zeit, sich zu fragen, warum und wofür man lebt. man wäre so beschäftigt, dass man froh wäre, überhaupt überlebt zu haben.

in zwei tagen ist es zwei monate her, dass ich meine freundin verlassen habe. ich habe gemeint, es würde mich nicht mehr so belasten, ich hätte es nun verarbeitet, es wäre vorbei. doch ich merke, es ist nicht vorbei. und es wird es für lange zeit auch nicht sein. immer, wenn es mir dreckig geht, kommt noch ein schlag mit dem hammer obendrauf: "hätte ich nicht, dann würde ich jetzt nicht."

im nachhinein sehe ich nur noch die schönen sachen.
die tolle zeit, die wir zusammen verbracht haben.
wie wir zusammen gelacht haben.
wie wir zusammengepasst haben.

und dann muss ich mich immer wieder vor mir selbst rechtfertigen, warum ich dich verlassen habe. in der hoffnung, dass ich das ein für alle mal klarstellen kann, schreibe ich diesen text.

aus irgendeinem grund war ich nicht zufrieden. vielleicht war es schlicht nicht genug. vielleicht aber kann ich den hals nicht voll genug kriegen - wenn ich schon viel habe, will ich noch mehr. hans dampf im schneckenloch.

HansDampf damian = new java.maerchen.HansDampf.HansDampf();
SchneckenLoch meinLoch = new java.maerchen.SchneckenLoch.SchneckenLoch();
meinLoch.put(damian);
while(true) {}

wahrscheinlich werde ich nie wissen, ob ich ein hans dampf bin. und falls ich es jemals doch wissen sollte, so ist es dann sicherlich zu spät.

in os x, every user has a long name, like "Administrator", and a short name, like "admin". throughout the system they can be used as synonyms, except if you work with unix tools in a terminal. on unix level, only the short name is registered.

the long name can be modified from the system preferences, but having the short name set up once, it stays the way it is - officially, there is no way to change it. inofficially, there are ways to do it nevertheless.

a nearly complete guide can be found on www.rts-software.com. i made a local copy just in case the link broke. it indicates you the most important steps. but if the user name you want to change is the primary user (and administrator) of the computer, there are some additional steps to take:

  1. after replacing the home folder, there might be a folder which has the same name as your old user, because programs you use (or quit) after changing the home folder name will write files into your old ~/Library folder. delete this folder using the root account.
  2. after new login with new name, the current user has no rights to write in the applications folder. this is because the user is not yet registered as administrator. i guess there are two possibilities:
    • open the system preferences, select accounts, the newly created account, tab security, and mark the field "allow this user to administer this computer".
    • when doing the action described above, you enable the new user to administer, but you don't disable the old one. to make this more properly, open the netinfo manager, select /groups/admin, and replace the old with your new name.
  3. also in the netinfo manager, the old user continues to exist in /groups. select it, replace the old name with the new, and save.
  4. and finally, your system may still have a computer name related to the old name, accessible in the sharing settings of the system preferences.

now all traces of the old username should be gone. enjoy your new user!

(i will indicate the changes also to bryan schappel from rts-software.com so you might find some steps mentioned twice.)

if you want to write tex / latex files, there are two components you need: first a editor, and second the latex engine.

the editor can be any basic texteditor such as vim or emacs, or it can be more specified for the task of creating latex files, such as texshop, itexmac or texmaker. i will concentrate on texmaker and give here a detailled installing instruction.

you can get the latex engine with fink, or also with i-installer, which i will use here.

download (make sure you go for the II2.dmg and not the source code from sourceforge.net), copy to your hard drive, launch the i-installer. close the welcome dialog (dismiss) and select "known packages i-directory..." from the i-package menu. select the tex package and click "open i-package". in the new window that opens you choose the button "install & configure", and most probably a basic installation will do. also the 2004 version is your best choice.

for the texmaker editor, you best get the binary package for os 10.3 from www.xm1math.net/texmaker/, and follow the instructions on the website - untar, go to the directory, launch sudo sh INSTALL.sh.

if you get the "could not start the command" error when trying to build a latex file, then you should execute the ADDTEXPATH.sh script, logout and back in again. if it still doesn't work then, you probably have no latex engine installed, see the beginning of this entry.

if the texmaker binary doesn't work for you, you might want to checkout the entry to compile texmaker from scratch.

to be able to compile texmaker from scratch, you will need the qtlib. i will give you a step-by-step instructions to compile texmaker and qtlib from scratch:

  1. get the qt-mac-free from www.trolltech.com
  2. install the qtlib:

    • unzip the archive
    • copy it to /Developer
    • rename the folder to qt
    • execute the following commands in your terminal:
      QTDIR=/Developer/qt
      PATH=$QTDIR/bin:$PATH
      DYLD_LIBRARY_PATH=$QTDIR/lib:$DYLD_LIBRARY_PATH
      export QTDIR PATH DYLD_LIBRARY_PATH
      ln -s $QTDIR/doc/man $QTDIR/man
      cd $QTDIR
      ./configure
      /usr/bin/make

      (get yourself a good book, it took 2h20' on my ibook 12'' 1.2ghz)

  3. download the texmaker source from www.xm1math.net/texmaker/ and uncompress it.
  4. execute the following commands:
    cd /path-to-your-unzipped-texmaker-source
    sudo sh ./BUILD.sh

  5. enter the requested information:
    path to QT3: /Developer/qt
    PREFIX: /usr
    SYSTEM: 2

after successfull termination there is a texmaker application in your /Applications/Texmaker folder.
