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

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 "||"

Returns the most recently modified file in the current (or specified) directory. You can also get the oldest file, via:

ls -t1 $* | tail-1 ;

tail -F /var/log/nginx/access.log | python -c 'exec("import sys,time\nl=0\ne=int(time.time())\nfor line in sys.stdin:\n\tt = int(time.time())\n\tl += 1\n\tif t > e:\n\t\te = t\n\t\tprint l\n\t\tl = 0")'

chmod authorized_keys so you don't get "Authentication refused: bad ownership or modes for file /home/user/.ssh/authorized_keys"

Where ^M is entered by ctrl-v-m (v then m). Especially useful on cygwin when checking into a version control system. If you're not using all cygwin tools (e.g. strawberry perl instead of cygwin perl) you'll find yourself dealing with this constantly.

-U tells grep to process the file as binary; it needs this to work

-I ignores binary files so you won't get false positives

-l only prints the filename instead of the offending lines

-r recursive

On a machine behind a firewall, it's possible to pass the proxy server address in as a prefix to wget to avoid having to set it as an environment variable first.
