I’ve been wanting to play with ECDSA ssh keys for a while (If memory serves, it became available in early 2011).

I like IPSec because it was designed to bind 2 networks together from the beginning.

Many operating systems use the EUI-64 algorithm to generate IPv6 addresses. This algorithm derives the last 64 bits of the IPv6 address using the MAC address. Many see this as a privacy problem. The last half of your IP address will never change, and with MAC addresses being somewhat unique, the interface ID becomes close to a unique “cookie” identifying your system.

Useful Apps

This is a list of some Apps (and links if they aren’t in the Apple App Store) I find useful (many are available through homebrew’s cask system).
