Geek tidbits: Postfix configuration for development and testing (December 7, 2011, 2) - From November:
We got the mail information for our Rails site, so I reconfigured the mail server. We’re doing a lot of development, and testing mail is much easier when you can send example mail addresses to one bucket of mail. Here’s how I set up the server to redirect everything addressed to @example.org to a

Setting up dynamic DNS with Tomato and Namecheap, and limiting SSH (September 23, 2013, 0) - We have a computer downstairs with backups of files, and I’ve been using it to explore Vagrant and development using virtual machines as well. It can be useful to be able to SSH into it from outside our network, so I spent some time setting up a dynamic domain name, port forwarding, and new limits

- Serial port? Parallel port? What are those?
