simple backup script
This script provides quick-n-dirty timestamped backups while preserving file extensions.
It echos to the console it's operations.
May be used on files or directories.
EXAMPLE
$ bk maxentropy.c
It automatically creates the '.backup' directory and timestamps the filename and copies it there (minute granularity).
Here is the script.
$ cat `which bk`
It echos to the console it's operations.
May be used on files or directories.
EXAMPLE
$ bk maxentropy.c
`maxentropy.c' -> `.backup/maxentropy~20080428d22h51.c'
It automatically creates the '.backup' directory and timestamps the filename and copies it there (minute granularity).

I map this to Meta-B since the native one only goes to "brightest" and
there is no other way to adjust it.

NetBeans 6.01 Visual Mobility Designer plugin fails to create new VMD files
Under investigation... using Debian.

Netbeans errors with toplinklib
Platform: Debian
Problem:
Netbeans 6 has integration with Sun Wireless Toolkit via the SWT plugin. Installing this plugin requires specifying a directory with a java(1) executable, but specifying /usr/lib/jvm/java-6-openjdk/jre/bin/ causes the install to fail since a jar(1) executable isn't in that directory.
However, /usr/lib/jvm/java-6-sun/bin/ works since this directory has symlinks to all important java6 related binaries. The /usr/bin directory works as well if one runs "sudo update-java-alternatives --list" then "sudo update-java-alternatives --set java-6-sun" (or use java-6-openjdk).
Anyway, half the plugins didn't work, and wiping out the ~/.netbeans* directories didn't fix anything.
Netbeans keeps complaining about needing org-netbeans-modules-j2ee-toplinklib although it is present and seems fine.
Solution:
Go to the plugins in Netbean, select Installed Plugins, select "Java Persistence" and uninstall. Then re-install this upon reloading Netbeans.
Now all the broken plugins start working again.
