Breaking the telnet addiction with netcat
After many years of use it's become almost second nature to type 'telnet open. Newer systems no longer install telnet by default: I can't think of a valid reason to keep telnet around (there are probably valid use cases).

George Wilson did an awesome introduction to ZFS de-duplication video, and it's a great place to get started. I'm planning to start testing out de-duplication as soon as my SSDs are ordered, and hopefully I will have some positive results to report!
