I have another article in the "You Don't Know jack" series from the ACM, now in the November Communications of the ACM (the print magazine), and a 5-minute video about it at https://vimeo.com/1017926413

This is a follow-on from Dave Taht's "bufferbloat" work, now a project called LibreQoS, where QoS stands for Quality of Service.

If you are having trouble with unintelligible con-calls or gaming lag, have a peek.
