In this podcast, the speaker reveals that If one has the latest version of the Citrix Access Gateway Enterprise with Global Server Load Balancing-enabled and the people are delivering resources to iPads and iPhones then they are in for a rough ride, here is why.

Recently, mobile, battery-powered embedded devices such as Personal Digital Assistants (PDAs), smartphones, and cellular devices, have become ubiquitous and increasingly capable. Worldwide, approximately 42 million smartphones and PDAs are shipped in the first half of 2006, and the predictions indicate that their sales will increase more than 57 percent by 2007. Given the proliferation and importance of these devices, users demand more capability from, and execution of increasingly complex applications on, these devices. A key limitation on the utility of these devices is the battery. Since it is extremely difficult to increase battery supply, the best option for extending battery life is to use software techniques and systems that are power aware.

Many applications are enabled by the ability to capture videos on a smartphone and to have these videos uploaded to an Internet connected server. This capability requires the transfer of large volumes of data from the phone to the infrastructure. Smartphones have multiple wireless interfaces – 3G/EDGE and WiFi – for data transfer, but there is considerable variability in the availability and achievable data transfer rate for these networks. Moreover, the energy costs for transmitting a given amount of data on these wireless interfaces can differ by an order of magnitude. On the other hand, many of these applications are often naturally delay-tolerant, so that it is possible to delay data transfers until a lower-energy WiFi connection becomes available.

With the advent of smartphone technology, it has become possible to conceive of entirely new classes of applications. Social swarming, in which users armed with smartphones are directed by a central director to report on events in the physical world, has several real-world applications. In this paper, the authors focus on the following problem: how does the director optimize the selection of reporters to deliver credible corroborating information about an event? They first propose a model, based on common intuitions of believability, about the credibility of information.

This paper investigates how to create ad-hoc audience response systems using non-specialist devices. The chapter revolves around two case studies: one involving the use of mobile phones and the other based on PDAs. Both case studies are carried out in tertiary education institutions, showing how these devices can be used to facilitate audience participation using devices that students might themselves bring to lectures. Both are evaluated from the perspective of the student and the educator, using a mixture of observational and interview-based techniques.

Moving to electronic patient records will greatly contribute to improving the quality and reducing the cost of patient care. However the frequency of breaches has reached a level that threatens to impede or derail this migration. This document discusses encryption, presenting its key role as a safeguard of sensitive information, while also recognizing its vulnerabilities and the residual risk after encryption to healthcare organizations. Robust hardware enabled security such as that provided by Intel AES-NI and Intel SSDs helps reduce the risk of breaches without significantly impacting system performance.
