    IMPRINT Imprint © 2014 Smashing Magazine GmbH, Freiburg, Germany ISBN (PDF): 978-3-94454087-0 Cover Design: Veerle Pieters eBook Strategy and Editing: Vitaly Friedman Technical Editing: Cosima Mielke Planning and Quality Control: Vitaly Friedman, Iris Lješnjanin Tools: Elja Friedman Syntax Highlighting: Prism by Lea Verou Idea & Concept: Smashing Magazine GmbH 2 About This Book Slow loading times break the user experience of any web- site—no matter how well crafted it might be. In fact, it only takes three seconds until users lose their interest in a site if they don’t get a response immediately. If another site happens to be 250ms faster than yours, then users are more inclined to switch to a competitor’s website in no time. Web fonts, heavy JavaScript, third-party widgets — all of them can sum up to become a real performance bot- tleneck. Nevertheless, tracking that down does not only improve loading times but also results in a much snappi- er experience and a higher user engagement. In this eBook, we’ve compiled an entire selection of front-end and server-side techniques that will help you tackle such bottlenecks. Find out how to speed up exist- ing websites, build high-performance sites (for both mo- bile and desktop), and prepare them for heavy-load situa- tions. Furthermore, you’ll learn more about how perfor- mance improvements and a 97–99 Google PageSpeed score were achieved on Smashing Magazine, as well as how optimization strategies can enhance real-life projects by taking a closer look at Pinterest’s paint performance case study.

  • Firefox Android Reader Mode
    Firefox android reader mode Continue Image: Firefox Development Firefox Preview, Firefox's restored Android app, is moving smoothly together, and this week one of its best features received a substantial update. Mozilla added browser extension support to Firefox Preview back in February, but you can only install one addition: uBlock Origin. Mozilla's latest test builds for Firefox Preview have added five more add- ons to the mobile browser that can be installed from the app settings, and they're all stunning: Screenshot: Brendan HesseDark Reader - automatically includes a dark mode for (most) websites, even if the page usually doesn't have one. HTTPS Everywhere - Adds HTTPS encryption to websites whenever possible. NoScript - Warns you about potentially dangerous web-page scripts and lets you decide whether they will be running or not. Privacy Badger - Blocks internet trackers hidden on the sites you visit. Image Search - Allows you to select and reverse search for images of any images you find while viewing. These new add-ons are available in the latest version of the developer's Firefox Preview. You can try them early by downloading Nightly Build from Google Play. While Night builds are designed for developers and often suffer from stability issues, downloading it so won't re-write any other version of Firefox Preview you've installed. If something doesn't work, you can just delete the browser and swap back for the more stable version of Firefox Preview you used before. New additions should be available in other versions of the app soon anyway. How to install add-onsInstall Firefox Preview Night Assembly from Google Play Store.

  • A Survey Onmobile Operating System and Mobile Networks
    A SURVEY ONMOBILE OPERATING SYSTEM AND MOBILE NETWORKS Vignesh Kumar K1, Nagarajan R2 (1Departmen of Computer Science, PhD Research Scholar, Sri Ramakrishna College of Arts And Science, India) (2Department of Computer Science, Assistant Professor, Sri Ramakrishna College Of Arts And Science, India) ABSTRACT The use of smartphones is growing at an unprecedented rate and is projected to soon passlaptops as consumers’ mobile platform of choice. The proliferation of these devices hascreated new opportunities for mobile researchers; however, when faced with hundreds ofdevices across nearly a dozen development platforms, selecting the ideal platform is often met with unanswered questions. This paper considers desirable characteristics of mobileplatforms necessary for mobile networks research. Key words:smart phones,platforms, mobile networks,mobileplatforms. I.INTRODUCTION In a mobile network, position of MNs has been changing due todynamic nature. The dynamic movements of MNs are tracked regularlyby MM. To meet the QoS in mobile networks, the various issuesconsidered such as MM, handoff methods, call dropping, call blockingmethods, network throughput, routing overhead and PDR are discussed. In this paper I analyse the five most popular smartphone platforms: Android (Linux), BlackBerry, IPhone, Symbian, and Windows Mobile. Each has its own set of strengths and weaknesses; some platforms trade off security for openness, code portability for stability, and limit APIs for robustness. This analysis focuses on the APIs that platforms expose to applications; however in practice, smartphones are manufactured with different physical functionality. Therefore certain platform APIs may not be available on all smartphones. II.MOBILITY MANAGEMENT IP mobility management protocols proposed by Alnasouri et al (2007), Dell'Uomo and Scarrone (2002) and He and Cheng (2011) are compared in terms of handoff latency and packet loss during HM.

  • An Empirical Analysis of Energy Consumption of Cross-Platform Frameworks for Mobile Development
    An Empirical Analysis of Energy Consumption of Cross-platform Frameworks for Mobile Development Matteo Ciman1, Ombretta Gaggia aDepartment of Mathematics, University of Padua, Padua, Italy Abstract The increasing fragmentation of mobile devices market has created the problem of supporting all the possible mobile platforms to reach the highest number of potential users. One possible solution is to use cross-platform frameworks, that let develop only one application that is then deployed to all the supported target platforms. Currently available cross-platform frameworks follow different approaches to deploy the final application, and all of them has pros and cons. In this paper, we evaluate and compare together the current frameworks for cross-platform mobile development considering one of the most important aspect when dealing with mobile devices: energy consumption. Our analysis shows and measure how the adoption of cross-platform frameworks impacts energy consumption with respect to the native mobile development, identifies which are the most consuming tasks, and tries to define a final rank among all the different approaches. Moreover, we highlight future development necessary to improve performances of cross-platform frameworks to reach native development performances. Keywords: Energy consumption, mobile development, performance measurement, web technologies, cross-platform frameworks 1. Introduction Smartphones are rapidly becoming more and more present in everyday life of users. Thanks to their increasing computing capabilities and an ample set of different sensors, e.g., accelerometer, barometer, environmental thermometer, 5 etc., smartphones play both the role of mobile workstations and of augmented devices, able to sense the environment and monitor user activities. Smartphones can be used for context awareness [1], user activity recognition [2, 3], health monitoring [4], etc.

  • Native Cross-Platform Mobile Application Development
    Native Cross-platform Mobile Application Development by W. de Kraker (0815283) CMI-Program Informatics – Rotterdam University August 14, 2012 First supervisor Mr. Y. S. Tjang Second supervisor Mr. A. Chamani Abstract Nowadays mobile devices are vastly integrated into modern society. They bring us one step closer to satisfy our ever growing need to have information available anytime, anywhere. To help gain access to information on mobile devices we use software applications, so called apps. However, the fragmented nature of today’s mobile ecosystem poses a challenge for developers to develop apps which are suitable to run on all mobile devices, since there is no de facto standard in cross-platform app development. Currently there are several solutions available to solve the cross-platform challenge. Lunatech, having expressed its interest in mobile app development, would like to know which solution, if any, suits Lunatechs needs. A study has been set up in order to resolve this question, the results of which are laid out in this thesis. ii Versions Version Date Author Details 0.1 12/07/2012 W. de Kraker Intial draft 0.2 20/07/2012 W. de Kraker Improved main research structure 0.3 08/08/2012 W. de Kraker Changes based on feedback from Mr. Y.S.

  • The Usage of Smartphone and Mobile Applications from the Point of View of Customers in Poland
    information Article The Usage of Smartphone and Mobile Applications from the Point of View of Customers in Poland Witold Chmielarz Faculty of Management, University of Warsaw, 00-927 Warsaw, Poland; [email protected] Received: 20 March 2020; Accepted: 15 April 2020; Published: 17 April 2020 Abstract: The main objective of this article was to identify the conditions for the use of smartphones and mobile applications in Poland in the second half of 2018. The scope of the present analysis was limited to a selected sample of more than 470 respondents, and it examined the group of the most active users of smartphones and mobile applications. The author adopted the CAWI (computer associated web interview) method, which was previously verified by a randomly selected pilot sample, in his study. The obtained results were compared with the findings of other studies. They indicated that users of smartphones and mobile applications in Poland do not differ in their assessments from users in Europe and around the world. In this context, the key implication for researchers is the identified level of development of the use of smartphones and mobile applications in Poland at the end of 2018. The main limitation of the research was the selection of the research sample, which consisted only of members of the academic community. The scope of this article aimed to fill a gap in terms of the quantitative and qualitative methods that are applied to examine the use of mobile devices and mobile software. At the same time, this study creates the foundations for further research on intercultural differences.
