Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Thanks! I created command "calc" from this that I can use from the command line at any time (faster than echo "equation" | bc)

~/bin/calc

#!/bin/bash

ARG=("$@")

x=$( printf "%s" "${ARG[@]}" )

calc(){ awk "BEGIN{ print $* }" ;}

calc $x
