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

This command allows you to stream your log files, including gziped files, into one stream which can be piped to awk or some other command for analysis.

Note: if your version of 'find' supports it, use:

find /var/log/apache2 -name 'access.log*gz' -exec zcat {} + -or -name 'access.log*' -exec cat {} +

Tar's up $DIR locally (w/bzip2) and sends remotely to $HOST:$PORT where netcat listens (using openbsd netcat). Start up receiving side command first, then execute this.

CSS=$HOME/.config/google-chrome/Default/User\ StyleSheets/Custom.css sh -c 'test -f "$CSS.off" && mv "$CSS.off" "$CSS" || mv "$CSS" "$CSS.off"'

A very simple command to toggle Chrome?s default style sheet. It uses the test command to see if the "Custom.css.off" file exists, if so, it will become "Custom.css", and if not, "Custom.css" is moved to "Custom.css.off" Thus, swapping.

This is accomplished with "&&" and "||"
