Since 2009, DevOps, the combination of development and operation, has been adopted within organizations in industry, such as Netflix, Flickr, and Fotopedia. Configuration management tools have been used to support DevOps. However, in this paper we investigate which Knowledge, Skills, and Abilities (KSA) have been employed in developing and deploying modern web applications and how these KSAs support DevOps. By applying a qualitative analysis approach, namely grounded theory, to three web application development projects, we discover that the KSAs for both Software Development and IT Operator practitioners support the four perspectives of DevOps: collaboration culture, automation, measurement, and sharing.

The purpose of this paper is to examine accuracy, security, and architecture impacts and challenges of mobile and web technologies through the case study of collecting geolocation field data in Washington (WA) State water resources. Effective management of water as a public resource relies on the capture, storage, and retrieval of accurate geographic position data. This is also true of a broad range of business domains beyond water resources, such as earth sciences, city planning, and navigation to name a few. Application developers must choose how to capture this information (with enough accuracy to be useful for its intended application) and get that data to a place where it can be processed and used. A traditional monotonic application using a Global Positioning System (GPS) and a mobile app using a smartphone are available today. The advent of HTML 5 now allows the development of a mobile web app, which is not dependent on any particular smartphone platform. These multiple technical options lead to two research questions: How does an HTML5 mobile web app solution work in terms of accuracy, security, and architecture, compared with a GPS-based solution and a mobile native app solution for collecting geolocation field data? And second, as HTML5 mobile web apps are a relatively new technology, what best practices can we uncover to assist in the process of choosing between an HTML5 mobile web app and a mobile native app, and also what are the best practices for building a mobile web app that can operate offline? To answer these questions, we build an HTML5 mobile web app called "LocationSharpener" for collecting GPS locations leveraging three of the new HTML5 features: IndexedDB, AppCache, and GeoLocation. We use the mobile web app to collect locations of water resources facilities like wells and diversions and analyze how accurately the app collects the geolocation data. We apply threat risk modeling to the mobile web app to analyze its security and privacy compared to that of the native mobile app approach. In addition, by documenting the architecture of the mobile web app with multiple views, we analyze how HTML5 affects the architecture and present best practices for building a mobile web app that can operate online and offline. The analysis of location accuracy shows the HTML5 mobile web app approach provides acceptable location accuracy even when offline. Threat modeling demonstrates that, in contrast to native mobile apps, mobile web apps offer a clear advantage to users and developers: an isolated execution environment makes it more difficult for a malicious mobile web app to read private data; As an outcome of the architecture documentation we also propose new best practices of developing a mobile web app using HTML5: the developer must consider two subsystems for online and offline use cases and a sequence of connected, disconnected, and connected deployment modes. Also, standards-based web apps are portable across virtually any operating system. This also eases the burden on developers, since ...

Conventional water quality monitoring and bird species observation were recorded using pen and paper. Moreover, experiments can usually only be conducted in limited areas due to the high cost of the water monitoring equipment. Consequently, not enough data could be collected to find the abiotic interactions between water quality factors and bird habitat. To resolve this problem, the proposed smart phone based system can transmit the water quality measurements and observed quantity of each bird species to the back-end server via a 3G network. This server functions as a ubiquitous information center where all measured and observed data are stored. Fuzzy C-means is applied to cluster water quality factors and bird species. The clustering results of bird quantity are then used to calculate the Simpson's diversity indices. Based on the results from the water quality factors and biodiversity index pattern trees (PTs) are constructed to find the abiotic interactions between them. The PTs can be further transformed into IF-THEN rules to provide references for researchers to conduct environmental protection. Experimental results are given to verify the applicability of the proposed system in finding the abiotic interactions.
