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

good one.

Comment by Habitual 218 weeks and 4 days ago

Could you explain the command ? I pasted it on my bash terminal, nothing happened.

Comment by ankush108 218 weeks ago

after pasting the above command, enter:

hourglass $int

where $int can be any positive integer.

Comment by capncanuck 217 weeks and 6 days ago

I wouldn't call that an "hourglass". I'd call it a "spinner". In Bash and some others which support [[ ]], use this: while (( $SECONDS < s )). You only need one echo if you use a carriage return: echo -en "$f\r"; sleep .2s and you don't really need the double ampersands. Add RETURN to your trap and you won't need the extra tput at the end.

like this!!!!!

Comment by gudie 217 weeks and 4 days ago

Awesome advice unixmonkey.. Everything you suggested worked other than the only one echo... the \b in the second echo is what backspaces the first char
