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

Tired of switching between proxy and no proxy? here's the solution.

Replace with your largest local subnet. replace with your proxy information.. Note this only works with a proxy server configured for passive setup..

Now your firefox transparently proxy's stuff destined outside your network.. and Doesn't proxy stuff inside your network. as well as all your other favorite web applications. curl, wget, aria2 ect.


There are 3 alternatives - vote for the best!

As I share a common .bash* between several machines and considering I don't always activate proxy here is an alias for wget :

[ $(/sbin/ss -talp|grep ':\(9050\|8118\)'|wc -l) -eq 2 ] && {

alias wget='http_proxy= ftp_proxy= /usr/bin/wget';

alias wgetp='/usr/bin/wget --no-proxy';

} || alias wget='/usr/bin/wget --no-proxy'
