So, after this visit I thought about models… and this is a real advantage to textual models because if you have a visual impairment
you can still create, read and interpret textual models! (even your computer could read the model to you… )
So, are your models barrier-free?

To be honest there are situations I like a graphical representation of models but only because I can see!

I can only recommend this experience to anyone. It gives a real impression of the life with a visual impairment and you will be impressed how fast the human body adapt to this new situation.

But this weekend I setup a new iTunes Library on my iMac to have really all my songs in this Library. And as I copied some songs from my MacBook Pro I saw that the iTunes Folder no longer is iTunes Music but iTunes Media. And within there is a new folder “Automatically add to iTunes”…

So this is great! I only had to copy my new songs to this folder and iTunes took them into the library. How cool is that?
Normally I buy my songs on my iPhone and sync it to my MBP and now I have just to copy these new songs into this folder, great, thanks Apple!

Update: Maybe it is a good idea to export my library from time to time and import into a new library after an iTunes Update…

As of a new feature of Subversion 1.6 there is a new conflict type called Treeconflict.
Read here in Detail when you have to expect unresolvable conflicts if your subversion server is not 1.6 or higher…

sudo softwareupdate -i -a

will install all available updates from the Terminal! Great, works fine!

This will install the SVN Client to

/opt/subversion

with the compiled Apache Modules included in

/opt/subversion/lib/svn-apache

Also the installer creates symbolic links for the svn-executables in your

/usr/local/bin

folder so be sure to have it in your path before /usr/bin.
To check this, just try **svn help** and check the version.

Ok, after installing your Client, all you have to do is to exchange the Apache modules and restart.
So the following will script will do:

  cd /usr/libexec/apache
  sudo cp mod_dav_svn.so mod_dav_svn.so.orig
  sudo cp mod_authz_svn.so mod_authz_svn.so.orig
  sudo cp /opt/subversion/lib/svn-apache/mod_* .
  sudo apachectl restart

To check your Apache-Modules just point your browser to your repository (don’t use websvn here) and check the version like in the screenshot mentioned.
Be careful about your browser cache!

Done, upgraded your svn and your apache modules!

So first for the Apache.

Apache

If you go to your System-Preferences and then to Sharing, you will see an entry called “Web-Sharing”. If you enable this feature your apache will start up.

To check if your Apache is running point your browser to http://localhost. You should see the following:

Fine, now for some more Details on the built-in Apache we need later on. The Apache has some folders and configuration-files that we will use later and that are the only ones you will mostly need to edit.

Folders

So far so good, as mentioned this is about to use SVN on your Mac. And here we go:

SVN

So you have SVN already shipped with your mac. Therefore just open your Terminal and type svn help. Hopefully you will see the following:

For the next step, integrating your SVN with the apache, we need to create at least one Repository.
As for me, I created a folder /Users/Shared/repository. Here are all my svn-repositories. To create a new repository go to your terminal and enter the following

svnadmin create /Users/Shared/repository/myFirstSvnRepo

As our Apache is running under the user www, we have to change the rights on the repository or change the owner of the repository as SVN needs write-access. Use one the following:

  # Change Owner
  sudo chown -R www /Users/Shared/repository/myFirstSvnRepo
 
  # to allow other access
  sudo chmod -R 757 /Users/Shared/repository/myFirstSvnRepo
  # to allow group access
  sudo chown :www /Users/Shared/repository/myFirstSvnRepo
  chmod -R 775 /Users/Shared/repository/myFirstSvnRepo

Ok, now we should integrate this into the Apache. So open the following file in your favourite Editor:

/private/etc/apache2/users/yourUser.conf

Add her the following lines:

  LoadModule dav_svn_module     libexec/apache2/mod_dav_svn.so
  <Location /repos>
    DAV svn
    SVNParentPath /Users/Shared/repository
  </Location>

If you just want one SVN-Repository reachable use SVNPath instead of SVNParentPath and specify the repository directly. Fine, lets test this. Restart your apache by sending the following command in your terminal:

sudo apachectl restart

Now point your browser to http://localhost/repos/myFirstSvnRepo. You see something like:

Ok, and we should create one folder in this repo so type the following

svn mkdir http://localhost/repos/myFirstSvnRepo/trunk -m "test"

If you see a Committed Revision 1. you are fine. Now for a second nice feature.

WebSVM

Download WebSVN from here. Extract the files and either copy the folder to your DocumentRoot or copy it somewhere you like and create a symbolic link in your DocumentRoot. As I prefer the latter, here is how you do it:

  # ln -s /REALPATH SYMBOLIC-LINK-NAME
  ln -s /PATH-TO-YOUR-WEBSVN-FOLDER websvn

After you’ve done this, open the Apache Conf (/private/etc/apache2/httpd.conf) and search for the following String

#LoadModule php5_module        libexec/apache2/libphp5.so

Found?
Great, uncomment this line by removing the #. Restart your Apache. Remember the command? (ok, here it is again: sudo apachectl restart)

Now browse this url http://localhost/websvn

Hmm… nice… but not what we expected, right?

But WebSVN tells us, what we are missing, so let’s go, last step, creating the config. You can simply go to your WebSVN Folder/include and copy distconfig.php to config.php. Then open config.php and find the following lines and enter your paths:

// $config->setSVNCommandPath('Path/to/svn and svnlook/ e.g. c:\\program files\\subversion\\bin');
...
// $config->parentPath('Path/to/parent (e.g. c:\\svn)');

And now try to refresh your Browser… should now look like this:

Congratulations, WebSVN is up and running!

You can now take a deeper into the config.php file, there are a lot more things to configure.

So, hope you had fun discovering how much your Mac has already available for you!

  ls | pbcopy                 # Will copy the output of ls to the clipboard
  pbpaste                     # Will paste the contents of the clipboard to Console

Felix has also the commands listed for Linux and Cygwin under Windows.

• Property has no file attribute. To load external Properties put them into a Nant-Script (<name>.build) and use the import-Task
• Include Nant-Contrib to your scripts, as useful as Ant-Contrib to Ant

  <loadtasks assembly="PATH-TO-NANT-CONTRIB/bin/NAnt.Contrib.Tasks.dll" />

• Property-Usage! This is really a difference to Ant foremost if you have to use Nant-Functions. If you want to use more than one Property passed to the function, keep in Mind that you
  just have to use the Property-Braces once! Example:

  ... <property name="nant.home" value="${environment::get-variable('NANT_CONTRIB_HOME')}"/> <property name="nant.contrib.dll" value="bin/NAnt.Contrib.Tasks.dll"/> <echo message="${path::combine(nant.home, nant.contrib.dll)}"/> ...

• To call a specific build file use nant /f:file.build instead of ant -f filebuild.xml
• In Nant you often have to use functions instead of properties

With these points in mind it will be no problem to write Nant-Scripts if you have Ant-Experience.

Hier die Tour von gestern: Gemütliche 2h Tour
Trails selbst auf dem iPhone kann man auch nutzen, um seine Fotos automatisch mit sogenannten Geo-Tags zu versehen. Dazu nutzt man zusätzlich
die freie Anwendung GPSPhotoLinker. Man zeichnet mit Trails den Weg auf und schießt ganz normal seine Fotos. Zu Hause kann man dann den Trail exportieren,
und die exportierte Datei in GPSPhotoLinker laden, Fotos dazu laden & GEO-Daten speichern. Wichtig hierbei, die Verknüpfung wir anhand der Uhrzeit vorgenommen,
man sollte also darauf achten, dass die Zeiten von den Wegpunkten des Trails zu den Zeiten der Fotos passen.

Alles in allem hat die Trails-Anwendung meine Erwartungen mehr als übertroffen, da sie wirklich Akku sparend arbeitet und man sogar Karten vorher runterladen kann, so dass man während des Wanderns, Radfahrens, etc. nicht mal zwingend ein Netz benötigt. Die Aufzeichnung von Wegen funktioniert natürlich auch ohne Karten und Online-Verbindung, aber mit Karten macht es einfach mehr Spass! Alles in allem haben sich die 2,39€ absolut gelohnt!
