However, I know […]

It seems that when I decided to send a filesystem from one server to another, I neglected to establish sufficient space existed. This morning, before I headed to BSDCan, I found that my server was very sluggish and slow to respond. Nagios was flagging all kinds of errors, some of which I’d never seen before.

I realized that making strong working relationships with others who share my passion is important. Not only does this solidify the community of which you are a member, it also helps you personally.

I’m starting to play with RabbitMQ as part of a new project. The first goal: get it installed and running. I’m going to do this in a jail running FreeBSD 9.2, but this should be the same if you running a non-jail.

With all of the activity surrounding the Heartbleed Bug, it was great to see so many people helping out to keep things secure. Of note was the actions of the FreeBSD team in getting out bug fixes.
