Hi. I'm jon.404, a Unix/Linux/Database/Openstack/Kubernetes Administrator, AWS/GCP/Azure Engineer, mathematics enthusiast, and amateur philosopher. This is where I rant about that which upsets me, laugh about that which amuses me, and jabber about that which holds my interest most: *nix.

I can haz iftop x 5?
No, apparently not.
Hrmmm...methinks I found the problem.
Err...whoops...
Now I can iftop all of the things. Yay!
No, apparently not.
