Install Perl Modules
How to install OTRS (Open Source Trouble Ticket System) on Ubuntu 16.04 Prerequisites Ubuntu 16.04. Min 2GB of Memory. Root privileges. Step 1 - Install Apache and PostgreSQL In this first step, we will install the Apache web server and PostgreSQL. We will use the latest versions from the Ubuntu repository. Login to your Ubuntu server with SSH: ssh [email protected] Update Ubuntu repository. sudo apt-get update Install Apache2 and a PostgreSQL with the apt: sudo apt-get install -y apache2 libapache2-mod-perl2 postgresql Then make sure that Apache and PostgreSQL are running by checking the server port. netstat -plntu You will see port 80 is used by apache, and port 5432 used by PostgreSQL database. Step 2 - Install Perl Modules OTRS is based on Perl, so we need to install some Perl modules that are required by OTRS. Install perl modules for OTRS with this apt command: sudo apt-get install -y libapache2-mod-perl2 libdbd-pg-perl libnet-dns-perl libnet-ldap-perl libio-socket-ssl-perl libpdf-api2-perl libsoap-lite-perl libgd-text-perl libgd-graph-perl libapache- dbi-perl libarchive-zip-perl libcrypt-eksblowfish-perl libcrypt-ssleay-perl libencode-hanextra- perl libjson-xs-perl libmail-imapclient-perl libtemplate-perl libtemplate-perl libtext-csv-xs-perl libxml-libxml-perl libxml-libxslt-perl libpdf-api2-simple-perl libyaml-libyaml-perl When the installation is finished, we need to activate the Perl module for apache, then restart the apache service. a2enmod perl systemctl restart apache2 Next, check the apache module is loaded with the command below: apachectl -M | sort And you will see perl_module under 'Loaded Modules' section. -
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.
