Migrating operating system instances across distinct physical hosts is a useful tool for administrators of data centers and clusters: It allows a clean separation between hard-ware and software, and facilitates fault management, load balancing, and low-level system maintenance. By carrying out the majority of migration while OSes continue to run, we(More)
Many software attacks are based on injecting malicious code into a target host. This paper demonstrates the use of a well-known technique, data tainting, to track data received from the network as it propagates through a system and to prevent its execution. Unlike past approaches to taint tracking, which track tainted data by running the system completely(More)

Commissural axon guidance requires complex modulations of growth cone sensitivity to midline-derived cues, but underlying mechanisms in vertebrates remain largely unknown. By using combinations of ex vivo and in vivo approaches, we uncovered a molecular pathway controlling the gain of response to a midline repellent, Semaphorin3B (Sema3B). First, we provide(More)
—A 64 2 64 element CMOS active pixel sensor (APS) for star tracker applications is reported. The chip features an innovative regional electronic shutter through the use of an individual pixel reset architecture. Using the regional electronic shutter, each star in the field of view can have its own integration period. This way, simultaneous capture of bright(More)
Many computer science programs suffer from low student retention rates. At Cal Poly San Luis Obispo, academic performance and retention rates among first-year computer science students are among the lowest on campus. In order to remedy this, we have developed a new CS0 course featuring different "tracks" that students can choose from (e.g. robotics,(More)
Provision of information on the environmental effects of consumption is often put forward as an appealing alternative to traditional means of environmental regulation such as permits and environmental taxes. When consumers in opinion polls are asked if their purchasing decisions would be influenced by information on environmental or ethical aspects of(More)
