This paper examines some of the potential challenges associated with enabling a seamless web experience on underpowered mobile devices such as Google Glass from the perspective of web content providers, device, and the network. We conducted experiments to study the impact of webpage complexity, individual web components and different application layer protocols while accessing webpages on the performance of Glass browser, by measuring webpage load time, temperature variation and power consumption and compare it to a smartphone. Our findings suggest that (a) performance of Glass compared to a smartphone in terms of power consumption and webpage load time deteriorates with increasing webpage complexity (b) execution time for popular JavaScript benchmarks is about 3-8 times higher on Glass compared to a smartphone, (c) WebP is more energy efficient image format than JPEG and PNG, and (d) seven out of 50 websites studied are optimized for content delivery to Glass.
Prior works have investigated the performance of web browser on desktop and smartphones from different perspectives such as caching, protocols and webpage content @cite_7 @cite_3 , webpage complexity @cite_8 and energy @cite_2 . In contrast, our major focus is, (a) to find out the web browsing performance issues on an underpowered device such as Glass and, (b) how today's webpage complexity and design contribute to such issues.

Scholars are increasingly citing electronic web references which are not preserved in libraries or full text archives. WebCite is a new standard for citing web references. To webcite a document involves archiving the cited Web page through www.webcitation.org and citing the WebCite permalink instead of (or in addition to) the unstable live Web page. This journal has amended its instructions for authors accordingly, asking authors to archive cited Web pages before submitting a manuscript. Almost 200 other journals are already using the system. We discuss the rationale for WebCite, its technology, and how scholars, editors, and publishers can benefit from the service. Citing scholars initiate an archiving process of all cited Web references, ideally before they submit a manuscript. Authors of online documents and websites which are expected to be cited by others can ensure that their work is permanently available by creating an archived copy using WebCite and providing the citation information including the WebCite link on their Web document(s). Editors should ask their authors to cache all cited Web addresses (Uniform Resource Locators, or URLs) prospectively before submitting their manuscripts to their journal. Editors and publishers should also instruct their copyeditors to cache cited Web material if the author has not done so already. Finally, WebCite can process publisher submitted citing articles (submitted for example as eXtensible Markup Language [XML] documents) to automatically archive all cited Web pages shortly before or on publication. Finally, WebCite can act as a focussed crawler, caching retrospectively references of already published articles. Copyright issues We present a micro-architectural side-channel attack that runs entirely in the browser. In contrast to previous work in this genre, our attack does not require the attacker to install software on the victim's machine; to facilitate the attack, the victim needs only to browse to an untrusted webpage that contains attacker-controlled content. This makes our attack model highly scalable, and extremely relevant and practical to today's Web, as most desktop browsers currently used to access the Internet are affected by such side channel threats. Our attack, which is an extension to the last-level cache attacks of , allows a remote adversary to recover information belonging to other processes, users, and even virtual machines running on the same physical host with the victim web browser. We describe the fundamentals behind our attack, and evaluate its performance characteristics. In addition, we show how it can be used to compromise user privacy in a common setting, letting an attacker spy after a victim that uses private browsing. Defending against this side channel is possible, but the required countermeasures can exact an impractical cost on benign uses of the browser. In a document network such as a citation network of scientific documents, web-logs, etc., the content produced by authors exhibits their interest in certain topics. In addition some authors influence other authors' interests. In this work, we propose to model the influence of cited authors along with the interests of citing authors. Moreover, we hypothesize that apart from the citations present in documents, the context surrounding the citation mention provides extra topical information about the cited authors. However, associating terms in the context to the cited authors remains an open problem. We propose novel document generation schemes that incorporate the context while simultaneously modeling the interests of citing authors and influence of the cited authors. Our experiments show significant improvements over baseline models for various evaluation criteria such as link prediction between document and cited author, and quantitatively explaining unseen text. Multiple entities in the smartphone ecosystem employ various methods to provide better web browsing experience. In this paper, we take a first comprehensive examination of the resource usage of mobile web browsing by focusing on two important types of resources: bandwidth and energy. Using a novel traffic collection and analysis tool, we examine a wide spectrum of important factors including protocol overhead, TCP connection management, web page content, traffic timing dynamics, caching efficiency, and compression usage, for the most popular 500 websites. Our findings suggest that that all above factors at different layers can affect resource utilization for web browsing, as they often poorly interact with the underlying cellular networks. Based on our findings, we developed novel recommendations and detailed best practice suggestions for mobile web content, browser, network protocol, and smartphone OS design, to make mobile web browsing more resource efficient.
