Standardspeicherort in Mac OS X iCloud ändern

Bei iCloud-fähigen Anwendungen unter Mac OS X ist bei jedem Speichern-Dialog iCloud als Standardspeicherort vorbelegt.
icloud Default. Wenn man dort keine Daten ablegen möchte, muss man in Textedit, Vorschau, etc. jedes Mal manuell umstellen. Über einen einfachen Befehl im Terminal kann man die eigene Festplatte als Standardort neu festlegen:

defaults write NSGlobalDomain NSDocumentSaveNewDocumentsToCloud -bool false

Essentials: ImageMagick

Für die automatisierte Bildbearbeitung ist immer wieder ImageMagick hilfreich. Die Bildbearbeitung ist insbesondere für die Kommandozeile gedacht und gerade für immer wieder anstehende Anpassungen schnell und unkompliziert.
Ein kleines Beispiel:
Aus diesem Bild
Bild vor der Konvertierung
werden mit einem kurzen Befehl zwei neue Dateien geschrieben. Die erste Umwandlung als Bilderstapel
Demo Bilderstapel
und noch eine Polaroid-Version
Demo Polaroid-Effekt
ImageMagick. It's magick!

When trying to access a port and Google Chrome gives you

Error 312 (net::ERR_UNSAFE_PORT): Unknown error

there are two ways to fix that problem:

  1. Rebuild from chromium sources (yuck!)
  2. start chrome with a parameter

For the second solution in Windows you will need to change the Start Menu entry to e.g. "C:\Documents and Settings\User\Local Settings\Application Data\Google\Chrome\Application\chrome.exe --explicitly-allowed-ports=nnnn" where nnnn is the port that has been blocked.

On the Mac you can either start chrome with the terminal with "
open /Applications/Google\ --args --explicitly-allowed-ports=PORTNUMBER" or create you own app with Automator


By default Chrome blocks the following ports:

Wunderlist - task management in the cloud

For task management in the cloud there is a neat little (free!) app available: Wunderlist from the Berlin based company 6Wunderkinder. It runs on all common PC operating systems including iOS devices and Android as well as in the browser.


Please be aware that the sync function uses the cloud, so all entries are stored on Amazon S3 servers. So this is not a secure solution for private data - for the shopping list that might be okay. YMMV.

One drawback with the current version: there is no export available. Since I don't like software with a lock-in I checked the local folders: on Mac OS X Wunderlist saves the data in the file ~/Library/Wunderlist/wunderlist.db, on Windows machines it is in c:\users\username\AppData\Roaming\Titanium\appdata\com.wunderkinder.wunderlist\wunderlist.db
Both files are SQLite databases which you can open with the SQLite Manager Firefox plugin.
With a SQL query you can extract the data from the tables "lists" and "tasks", join and export them to a CSV file.

Select,T.done,T.note,datetime(T.done_date,'unixepoch'), From tasks AS T INNER JOIN lists AS L ON T.list_id = order by

SQLite Wunderlist.db

The SQL query shown above is available for download as a textfile.

Update: In Wunderlist 2 the location of the SQLite database has changed, please see this post on

That should do it for the start...

Show the Library folder with Mac OS X Lion

By default the Library folder is hidden on Mac OS X Lion. Two options to get to the library folder:

  1. access it directly with Command+Shift+G from the Finder (or via the menu Finder > Go > Go to Folder) and type in ~/Library or
  2. disable the hidden library permanently with typing in the Terminal command "chflags nohidden ~/Library/"

Mac OS X Lion

Mac OS X Lion install is done as of today. If you upgrade your system and want to keep the installation file from the AppStore Download make a copy of it before starting the install process. After Lion is installed the huge file downloaded from will be deleted.

Warning: there is no Rosetta emulation layer any more - so all PowerPC programs on your system will not be running any more.
... and do plan some time for getting used to the new feature called "natural scrolling" :-)
