Contemporary Peer Code Review Practices and Associated Benefits
CONTEMPORARY PEER CODE REVIEW PRACTICES AND ASSOCIATED BENEFITS by AMIANGSHU BOSU JEFFREY C. CARVER, COMMITTEE CHAIR JEFF GRAY MUNAWAR HAFIZ RANDY SMITH MARCUS BROWN A DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Computer Science in the Graduate School of The University of Alabama TUSCALOOSA, ALABAMA 2015 Copyright Amiangshu Bosu 2015 ALL RIGHTS RESERVED ABSTRACT Prior research indicates that peer code review is an effective method for reducing the num- ber of defects and improving the quality of code. Besides maintaining the integrity of the code, code review spreads knowledge, expertise, and development techniques among the review par- ticipants. In the recent years, many Open Source Software (OSS) communities and commercial organizations have adopted ‘contemporary’ or ‘modern’ code review, an informal, regular, tool- based process. Because both OSS and commercial developers spend a significant amount of effort performing code reviews, the primary goal of this dissertation is to better understand contemporary code review, its non-technical benefits, factors that influence its outcomes, and its impact on peer impression formation. To address this goal, this dissertation describes empirical studies using surveys, software repository mining, and social network analysis. The first study is a survey of OSS developers to understand their collaboration and the process by which they form impressions of each other. The results suggest that coding-related factors influence impression formation the most among OSS developers. Therefore, the types of interactions where participants can judge a peer’s code or creativity (e.g., code review) should be crucial for peer impression formation. -
HP Mediasmart Connect
HP MediaSmart Connect HP MediaSmart Connect – Best Practices The HP MediaSmart Connect is a digital media receiver that transforms any HDTV into a digital experience.1,2 The HP MediaSmart Connect lets you enjoy your favorite photos, music, movies, and videos—stored on multiple PCs—in the comfort of your family room on your HDTV. Before you begin your set-up Inside the HP MediaSmart Connect box you will find the HP MediaSmart Connect unit, a power adaptor, an HDMI cable, a universal remote, an Installation and User’s Guide, a Set-up Poster, coupons for trying out Vongo and CinemaNow movie services,4 and a software installation CD. To install and use all key features of the HP MediaSmart Connect you should also have: • A High-definition TV with either component or HDMI inputs.2 • A PC running Microsoft Windows XP SP2 or later. You will need Windows Vista Home Ultimate or Premium1 (with optional TV Tuner card) to use the Extender for Windows Media Center functionalities.5 • A router with broadband access.3 If using wireless, for HDTV streaming we recommend using 802.11n6 routers with dual 2.4 and 5 GHz radios. Unless you use your router in dedicated “n” mode, we don’t recommend connecting BOTH your PC and the HP MediaSmart Connect to your router via wireless connection. We recommend connecting your PC to your router in wired mode. Unlike other media receivers that require PCs running the Windows Media OS, the HP MediaSmart Connect supports all Digital Living Network Alliance (DLNA)-compliant media servers and can stream content from a variety of systems, including: • PCs running Microsoft Windows XP (SP2) or later using Windows Media Player 11 (WMP11) • Macintosh or Linux-based computers running a DLNA-compliant media server, such as TwonkyVision, or TVersity. -

Andrew Shitov Raku One-Liners Getting the most of Raku’s expressive syntax for your daily routines DeepText — 2019 Raku One-Liners Getting the most of Raku’s expressive syntax for your daily routines © Andrew Shitov, author, 2019 In this book, you will find a lot of short programs, so short that they can be written in a single line of code. The seven chapters will guide you through Raku’s syntax elements that help to create short, expressive, but still useful programs. It is assumed that the reader knows the basics of the Raku programming language and understands programming in general.
