changing Java version on Mac crashed eclipse

Checking the javac version from command line told me I was using 1.5. To change this I changed the Current and CurrentJDK. This worked fine for Java programs run from the shell.

The next restart of eclipse failed. Remembering that there should be a new version for Cocoa by now I downloaded the new 64bit eclipse version. Crashed with the same error messages.

Changed -Dosgi.requiredJavaVersion in eclipse.ini to 1.6 -> crash

Added Info.plist in Eclipse.app the line to require a specific Java version -> crash

Searching the internet for a solution I encountered the changing the link to select a Java version will bite you. This should be done with Java Preferences (Spotlight). Unfortunately the tool didn't start. Setting the links back to A changed this. With this tool you change the ordered of the preferred Java version.

With this changes eclipse started - and noticeably faster. The Activity Monitor now shows Intel (64bit). On the shell javac is now also 1.6.

ERDesigner NG

Downloaded and installed the open source ER tool ERDesigner NG written in Java. This will run on Windows, Linux and Mac OS X.

SQLite is not supported. To start drawing a design you need to define a database connection. It is possible to use a dummy one.

Adding attributes to a table not difficult as you need to press update before you add a new attribute or the last one added will be lost.

You can't declare a private key. You need to define an index for an attribute, this will now become a private key.

After this I stooped and deleted the tool.

debian lenny default X settings

The default X windows installation in debian looks broken to me. The default screen size used was 1600x1200. To much for my old TFT. Trying to resize the resolution from Gnome failed (ALT-CTRL-- and resolution tool). This is because in xorg.conf are no screen resolutions defined.

Adding the following lines to the screen section fixed the problem:
  DefaultDepth 24
  Subsection "Display"
  Depth 24
  Modes "1280x1024"
  EndSubsection
