Cloud computing promises flexibility and high performance for users and high cost-efficiency for operators. Nevertheless, most cloud facilities operate at very low utilization, hurting both cost effectiveness and future scalability. We present Quasar, a cluster management system that increases resource utilization while providing consistently

Rotation in addition to free gravitational motion can produce oscillations in a large spherical mass of gas. The theory may provide an explanation of the variations of brightness in such objects as 3C273.

The observed absence of quasar redshifts larger than 3.53 is erroneously attributed to Richard Green and myself in "A boundary for the quasars" (Research News, 22 Jan., p. 388). Our survey of bright quasars does not cover redshifts larger than 2.2 because in choosing candidates we rely on the ultraviolet excess, which tends to disappear at larger ...
