Ooops, who would have thought that "sentient" Skynet will = actually wil have spend its formative years as a "self-learning" = AQM-system; might explain its propensity to throttle its subjects ;) >=20 > --=20 >=20 > Dave T=C3=A4ht > CEO, TekLibre, LLC > http://www.teklibre.com > Tel: 1-669-226-2619 > _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat
