DC is proposed for use in data centers as an alternative to AC distribution primarily based on publicized claims of efficiency improvements and energy savings. This paper shows that the most widely cited values for quantitative improvements are wrong and grossly overstate the efficiency differences between AC and DC, and that the latest AC and DC systems provide effectively the same efficiency....

MacroBase is a new kind of data analysis engine designed to prioritize human attention in large-scale fast data streams. Given increasing data volumes that are increasingly too large for manual inspection, MacroBase highlights interesting behaviors in streams and produces explanations for these behaviors that can be used for tasks including diagnostics, alerting, and root cause analysis. MacroB...
