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

Do not run this command if you already have ntpd running!

This needs to run as root, for example with sudo:

sudo ntpdate pool.ntp.org && sudo hwclock --systohc && sudo hwclock --adjust

This command will fetch accurate time from NTP servers and synchronize your system clock, then it will use the system clock to synchronize your hardware clock, and will calculate the time drift.

cd "$(mktemp -d)"

Tags: bash directory

This command create a new temp directory using mktemp (to avoid collisions) and change the current working directory to the created directory.
