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

If you need to randomize the lines in a file, but have an old sort commands that doesn't support the -R option, this could be helpful. It's easy enough to remember so that you can create it as a script and use that.

It ain't real fast. It ain't safe. It ain't super random. Do not use it on untrusted data. It requires bash for the $RANDOM variable to work.

If your version of curl does not support the --compressed option, use

curl -s http://funnyjunk.com | gunzip

instead of

firefox "$(grep -i ^url=* file.url | cut -b 5-)"
2014-10-08 05:56:27
User: nachos117

This command will use grep to read the shortcut (which in the above examle is file.url), and filter out all but the only important line, which contains the website URL, and some extra characters that will need to be removes (for example, URL=http://example.com). The cut command is then used to get rid of the URL= at the beginning. The output is then piped into Firefox, which should interpret the it as a web URL to be opened. Of course, you can replace Firefox with any other broswer. Tested in bash and sh.

This will display the system memory size in kb. If you want to see the value in mb, you can type:

You need the RANDR support enable, to enable it with an ATI card run:

aticonfig --set-pcs-str="DDX,EnableRandr12,TRUE"

To show your available output run:

Show disk space info, grepping out the uninteresting ones beginning with ^none while we're at it.

The main point of this submission is the way it maintains the header row with the command grouping, by removing it from the pipeline before it gets fed into the sort command. (I'm surprised sort doesn't have an option to skip a header row, actually..)

It took me a while to work out how to do this, I thought of it as I was drifting off to sleep last night!

Improvement on Coderjoe's Solution. Gets rid of grep and cut (and implements them in awk) and specifies some different mplayer options that speed things up a bit.
