Some few small insights

Wednesday, March 12th, 2008

Lately I have been overloaded above my capabilities. This did not prevent me from doing all kind of things, but most of them are too small to justify a real entry here, so I have decided to make a small collection of small stuff someone might need to know, in order to make it indexed in search engines. These small insights might save some time for someone. This is a noble cause.

1. Oreon is a nice overlay for Nagios, however, it is poorly documented, and some of the existing docs are in French. I have put hours on building it into a working setup, and I hope to be able to write down the process as is.

2. “Sun Java System Active Server Pages” does not support 64bit Linux installations – at least not if you’re interested in using it with your existing Apache server. Look here. Seems nothing has changed.

3. Under Ubuntu 7.10, Compiz suffers from a major memory leak when using NVidia display adapters. You can read about it in the bug page. I was able, thanks to this link, to workaround it using compiz –indirect-rendering . Does not see to cause any ill-effect on my display performance.

4. Suse 10 and wireless cards – This one is a great guide, which I would happily recommend.

5. Flushing the existing read buffer for your Linux machine (should never be done, unless you’re testing performance) can be done by running the following command:

echo 1 > /proc/sys/vm/drop_caches

Seems to be enough for today. Hope these tips help.
