What does system-config-network-tui do?

What does system-config-network-tui do? To find this out, run it and set the hostname to something weird like "booger". Then run a find across all files in the etc folder to look for files that matched. There are much better ways to do this....
sudo find /etc/. | xargs grep 'booger' -sl
As an alternative, run a series of find commands to see what was "touched".
#file accessed within a period of minutes
sudo find /etc -amin -2
#file status changed within a period of minutes
sudo find /etc -cmin -2
#file modified within a period of minutes
sudo find /etc -mmin -2

The bottom line is that system-config-network-tui is doing way more that simply touching a couple of lines in /etc/hosts and /etc/sysconfig/network.

Building GWT on Ubuntu.

After GWT was building, some of the test cases would fail. Most of them would simply exit with empty test logs. Of course this to had nothing to do with GWT. The default installation of Hardy includes libstdc++6 and the firefox libs included with GWT depend on libstdc++5. This was and easy issue to deal with (with some help from ssolka) except for wading through piles of output from ant -debug and junit.showoutput to get the problem to reveal itself.

“Locking assertion failure”... WTF?

I tried to build GWT today on a Ubuntu system. Compilation was failing during benchmarkviewer and was complaining about a “Locking assertion failure”. Well, come to find it, this of course has nothing to do with GWT. There is some sort of problem with how the JRE was built. Anyway... way to many rabbit holes later, I got on the right track and and found the fix.
