Hello world! We at the Hopkins Storage Systems Lab (HSSL) are trying to understand how you, the tech elite, access and use data and how you access the Internet on mobile devices. We are interested in you, because we think that your data-use habits may be indicative of what might become common in a few years time. We want to understand how you access and use data on mobile devices to improve the user experience on mobile devices. Specifically, we want to: - Improve disconnected operation; - Make accessing data faster; - Increase battery life; - Reduce network connectivity costs; and, - Simplify data management. We suspect that significant amounts of data that you use are downloaded on demand and that this data could be effectively prefetched. Although prefetching sounds easy enough, there are a number of issues that need to be considered: when should data be prefetched? what data should be prefetched? how do we avoid exhausting free space? how do we enable applications to coordinate the use of shared resources? To this end, we are conducting a user study. We'd like you to participate by running our data collection software, which gathers information about the data you use, your network connectivity, and your battery use. To help by running the data collection software, which should take about 10 minutes to install and not require any further interactions on your part, please visit, on your N900: http://hssl.cs.jhu.edu/~neal/woodchuck/smart-storage-logger.install or: http://tinyurl.com/wcssl For more information about Woodchuck, please visit: http://hssl.cs.jhu.edu/~neal/woodchuck/ Much of the data that we collect will be anonymized. No personally identifying data will be published. Data collection will last for approximately one year. Anyone with a compatible device may run the data collection software. Your participation in this experiment is entirely voluntary. Should you choose to participate, your data will be kept confidential to the extent possible by law. Only researchers involved in this study will see collected data. Published data will not include identifying artifacts (i.e., we will make every effort to prevent the identify of participants from being determined from the data we publish). Encryption will be used to transfer collected data and to verify the server to which that data is uploaded. If you have any questions or concerns, feel free to contact me at neal@xxxxxxxxxx or Randal Burns, the principle investigator, at randal@xxxxxxxxxx. Your assistance in helping us meet our research goals would be greatly appreciated. Thanks for your help! Neal Walfield P.S. This study is research. You will not receive any direct benefits from participating in this study. This study may benefit society if the results lead to a better understanding of how data is used on mobile devices. The study is taking place at the Whiting School of Engineering at the Johns Hopkins University in the United States.
