This talk is composed of two mini-talks. In the first half of the 
talk, I will talk about how I use operating system support to make 
trouble shooting misconfiguration easier. Troubleshooting 
misconfiguration is a frustrating process. In this work, I use a 
modified Linux, which supports checkpoint/rollback and speculative
execution, to allow users to explore many possible solutions for 
a configuration problem. The evaluation showed that user 
troubleshooting time is greatly improved with operating system 
support for three real world applications. I will conclude the first 
half by talking about some systems management work my research group 
is conducting for cloud environment. For the second half, I will 
switch gear to talk about Slingshot, a system that enables mobile 
phones to opportunistically use machines nearby to offload 



Ya-Yunn Su received her B.A. degree in Information Management from 
National Taiwan University in 2001, and her M.S. and Ph.D. degrees 
in Computer Science and Engineering from the University of Michigan 
Ann Arbor in 2004 and 2008, respectively. After graduation, she 
joined the Autonomous and Scalable Distributed Systems Group at NEC 
Labs in Princeton, NJ as a research staff member. After almost two 
years with NEC Labs, she joined the faculty of Computer Science and 
Information Engineering Department at National Taiwan University, 
where she is currently an assistant professor since August 2010. Her 
research interests include operating systems, systems management, 
mobile computing, and cloud computing.
