Thx for busting me up this morning! But what you say is not strictly true. When the RTT goes way, way, way up (as in email) it becomes much more possible to have an unresolvable heated argument that cannot be shut down down without invocation of godwin's law. Short RTTs (as in personal meetings - and perhaps, one day in a more bloat-free universe without annoying jitter), make it both more possible to have a heated argument... and a resolution. A shared beer, helps too, also. :) > -- > Mikael Abrahamsson email: [email protected] > _______________________________________________ > Bloat mailing list > [email protected] > https://lists.bufferbloat.net/listinfo/bloat -- Dave Täht Open Networking needs **Open Source Hardware** https://plus.google.com/u/0/+EricRaymond/posts/JqxCe2pFr67 _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
