A compact hydraulic particle separator apparatus is disclosed. The disclosed apparatus comprises an upper chamber and a lower chamber separated by a partition. A liquid fluid flow upwelling through the partition from the lower chamber is caused to mix with tangential jet of fluid flowing introduced above the partition in the upper chamber produces an upwardly-flowing cyclonic flow within the upper chamber. Particle mixtures containing low- and high-density particles and other solids are introduced into the upper chamber through a feed tube having a mouth that is offset from the center of the upper chamber. Low-density particles are immediately entrained in the cyclonic flow and swept upward and exit the apparatus.

A facility for evaluating an advertising strategy with respect to a subject website is described. The facility receives a specification of the advertising strategy. The specification indicates how to apply the advertising strategy to select one of a plurality of advertising campaigns in response to each page request against the subject website. The facility applies the advertising strategy in accordance with the received advertising strategy specification to a sequence of page requests earlier received against the subject website. The facility then assesses the results of applying the advertising strategy in accordance with the received advertising strategy specification to the earlier-received page requests.
