Streaming Sound via Airtunes (AirportExpress)

While using Airtunes via iTunes I messed around with the problem to stream the system sound to the AirportExpress (e.g. Youtube Music).
After looking through some forums I stumbled over a little tool called "Airfoil".

After installing it I can choose the AirportExpress as the output speaker for my system sound:

Now all system sounds are streamed to the AirportExpress and it's possible to play sound of youtube videos directly to the AirportExpress. The sound is a little bit delayed (so using it as movie sound stream is senthless).

DBVisualizer: ERROR: column c.reltriggers does not exist

DBVisualizer is one of my favourite database development tools because it's plattform and database independent and is really intuitive.

Since I updated my PostgreSQL Database Instance to V9 I get an error in DBVisualizer due to missing relations in the database.

It is possible to edit the statements DBVisualizer executes for displaying tables and data. Go to the Application folder and Right-Click on the DBVisualizer.app and Choose "Show package contents":

Then step down to the following directory

Now open the postgresql8.xml file and search and replace:

Search: (c.reltriggers > 0)

Replace: (/*c.reltriggers*/ 0 > 0)

Save and close the file. After a restart of the DBVisualizer everything should work fine.
