Review board

At the company (Navtech) I work for, I introduced a code review tool called "Review Board". An open source tool mainly developed
by vmware and used by many companies such as Google (Google Code Summer), Yahoo, Vmware,..
And now, my team and our adjacent team use it as well.
Very neat! Subversion integration, neat diff rendering (syntax highlighting), and the possibility to have good discussions about lines of code make it a very good tool for code reviews.

Firefox javaplugin insists on symlinks

If you were wondering why your java plugin doesn't work, it might be because
you copied

libjavaplugin_oji.so

instead of creating a symlink to it:

ln -s /javapath/jre/plugin/i386/ns7/libjavaplugin_oji.so \
$HOME/.mozilla/plugins/.

Not sure why it works only that way.

MySQL: Delete a subset in a table quickly

I found a fast way to delete a small subset of rows in a very big table (hundreds of thousands or millions).

See my comment on MySQL's DELETE Syntax page.
