Functions

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

Slow down IO heavy process

Some IO intensive process make the system unresponsive. This function periodically starts/stops a process, which hopefully releases some resources for other activities.

This function is useful when ionice is not available

Alternatives

There are 5 alternatives - vote for the best!

Terminal - Alternatives
slow () { [ -n $1 ] && while kill -STOP $1; do sleep 1; kill -CONT $1; sleep 1; done }

compare to alternative :

- directly tests the -STOP of the process to continue or stop loop,

- background operator should be set (or not) at the call of the function

For extension i suggest a slowPID() based on kill like above and a slowCMD based on killall.

Know a better way?
