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 limits the oputut of git log to one-line per commit and an abbreviated commit ID.

The command is useful for monitoring the use of the boxes and their connection IP.

Result file "sniff" is readable with GUI program "wireshark" or through CLI with the command:

tcpdump -f "sniff" -XX

Using ghostscript instead of imagemagick to convert pdfs into pngs. It keeps pngs with pdfs

After you execute a command (or shell script) in the background using

&, if you logout from the session, the command will get killed. To avoid

that, you should use nohup as shown below.

sed -e :a -e '$!N;s/\n/ /;ta'
tail -f /var/log/messages.log | while read line ; do echo $line | cut -d \ -f5- | sed s/\\[[0-9]*\\]// | espeak ; done

This alias is useful if you need to use some text often. Executing the alias will copy the text into your clipboard and then remove it after X seconds.

since we're repeating the command there after the semicolon, we only need one backtick

If you use colored ls(1), the broken symbolic links significantly differ from regular files and directories in the ls listing. In my case it is bright red. 0 is for getting the first place in the list.

find `pwd` -maxdepth 1 -exec ls --color -d {} \;
