Trying to Understand OSPF Summary Routes

While working through some OSPF configurations in preparation for my CCNA exam next week, I noticed something I thought was odd, and I don’t really understand why it’s behaving in this manner. I thought perhaps a networking expert can enlighten me.

Reverting Project Behavior in OmniFocus

I recently updated OmniFocus on my MacBook Pro to version 1.8, the latest version, and noticed something that was—to me, at least—quite disturbing.

Making Manual Edits to Dynamic DNS Zones

This is one of those posts that is as much for my own benefit as it is for others. For a few weeks now, I’ve been working on a dynamic DNS setup for my home/home office network involving BIND and the ISC DHCP daemon running on a pair of OpenBSD virtual machines. I finally got it to work (thanks in no small part to this article and this how-to post) and then found that I needed to make some manual edits to the DNS zones.
