An update too Fedora a while ago started causing some unexpected behavior with my dotfiles. Specifically the way I was handling my SSH agent. My SSH keys when added to my agent automatically expire after a couple of hours.

I regularly find myself in need of generating a quick SSL key and certificate pair. I've been using a one-liner for a while to generate these certificates. No annoying user prompts just a quick fast certificate pair.

Anyone that has used SSH, Tmux or Screen for a while will have inevitably dumped excessive output to their terminal. Depending on the size of the output you may have experienced the dreaded lockup. That horrible realization seconds after you hit the command where signals just stop working and you just have to sit there and wait for your terminal to catch up.

While working through a problem I found it would be immensely useful to be able to enumerate all of the current subclasses of a particular class. After thinking about this for a while I settled on a good old friend of mine, ObjectSpace.

I needed to generate crypt-style SHA512 passwords in ruby for an /etc/shadow file. After a bunch of Googling and messing around with the OpenSSL library I finally found a very simple built-in way to handle this.
