Set Author Name in eclipse.ini
Eclipse uses the system username by default. This is not always useful. Especially if you can’t choose the username on your own. To get around this just add “-Duser.name=Max Mustmann” (without quotes!) in your eclipse.ini somewhere after vmargs.

Windows 7 Library Icon
If you want to change the icon of your custom library in the windows 7 file explorer you have to edit a file with your favourite editor. I found the file under the following url: C:Users<username>AppDataRoamingMicrosoftWindowsLibraries<library-name> There I added <iconReference>C:usrlocaleclipse_indigoeclipse.exe</iconReference> after “<isLibraryPinned>true</isLibraryPinned>”

I tried to run openproj under ubuntu 12.04 with the latest jdk7 from oracle. Openproj complains that the java vendor should be sun instead of oracle.

I was just messing around with postgresql and table partitions and tablespaces. Here is a short SQL script that uses a virtual table that is partitioned by the modulus of the id column.
