Ubuntu: Getting Java Applets to work with Firefox

I was having problem to get Applet working in Firefox, primarily because I work with manually installed JDKs (that is not downloaded using apt-get). I did the following to get Applets working going through the following procedure.

locate libjavaplugin_oji.so

After I do this I will get the list of this file present in my machine. In my case one of the paths was -

/opt/jdk1.6.0_01/jre/plugin/i386/ns7/libjavaplugin_oji.so

Now I did the following and restarted my machine -

sudo ln -s /opt/jdk1.6.0_01/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla-firefox/plugins/libjavaplugin_oji.so

After this I got applets to work in Mozilla Firefox. Just for fun delete the symlink and without restarting the browser check whether you can see the applet or not :).

Propagating GIT commands to its submodules

GIT submodules is an idea (of many) that actually played an extremely important role in me moving to GIT. As a new user I started playing around with GIT and I noticed that GIT commands executed on the parent module is not propagated to the child modules. In some use cases it would be extremely useful (at least for me) to be able to be propagate a command from the master module to all its child at all depth. I wrote this bash shell script to simply propagate commands from parent to its child. To use this script you can simply do the following (I am assuming that the TXT will have the name git-modules and will be an executable in $PATH):

for: git-pull
do: git-modules pull

for: git-status
do: git-modules status

for: git-commit -a -m "This is a test commit"
do: git-modules commit -a -m "This is a test commit"

for: git-checkout master
do: git-modules checkout master

Basically any git-X command can be simply be done as "git-modules X args-as-usual".

I would really appreciate/welcome criticism, feedback and addition to the script. I will be publishing it to the repo.or.cz tomorrow after a little bit more testing.
