O desenvolvimento de software é uma atividade intensive em esforço humano. Assim, a forma como os desenvolvedores encaram suas tarefas é de suam importância. Em um ambiente como o usual em projetos de FOSS (free/open source software) em que profissionais (desenvolvedores pagos) compartilham os esforços de desenvolvimento com voluntários, a moral da comunidade de desenvolvedores e usuários é fundamental. Neste artigo, apresentamos uma análise preliminary utilizando técnicas de análise de sentimentos realizada em um projeto de FOSS. Para isso, executamos a mineração da lista de endereços eletrônicos de um projeto e aplicamos as técnicas propostas aos participantes mais relevantes. Embora a aplicação seja limitada, no momento atual, experamos que essa experiência possa ser benéfica no future para determiner situações que possam afetar os desenvolvedores ou o projeto, tais como baixa produtividade, abandono do projeto ou bifurcação do projeto, entre outras.

Indonesia is an archipelago country in which the tourism sector plays a role as an economic locomotive. In 2016, Indonesia joined the World Halal Tourism Award (WHTA) and won 12 awards, three of which were won by West Sumatra. Bukittinggi is the principal city of tourism in West Sumatra. There are many halal hotels and restaurants and 190 mosques available in the city. Unfortunately, the information regarding the mosque locations is still inadequate. For this reason, this research was conducted in order to develop a web-based and mobile-based geographic information system (GIS) for places of worship information (GPWI) to make it easier for Muslim tourists to find mosques, and other tourism objects and facilities. This paper reports on the development of the GPWI. The development of the GPWI employed the waterfall method. The GPWI allowed tourists to find mosques based on specific criteria, whose output showed them the location, information, route, and local transportation available to get to the mosques as well as other tourism objects and facilities around the mosque. The GPWI was developed using Free Open Source Software (FOSS) PostgreSQL/PostGIS, PHP, JavaScript, and Basic4Android. The spatial-based database and programs that were used to develop this GPWI are the main contributions of this study. Based on the product evaluation, the GPWI successfully met the needs of Muslim tourists in finding mosques during their visits to Bukittinggi.

Currently, most of basic control engineering lectures teach both mathematic model and control of an inverted pendulum to explain stability problems in dynamic systems. The inverted pendulum system is a pendulum controlled with a certain force in order to stand in balance around vertical equilibrium line. Hence this system is a highly unstable system and needs stabilization methods using a  kind of controller. This paper describes how to design a Proportional Derivative Integral (PID) controller via root locus technique to stabilize it and realization of its interface system for monitoring angle trajectory. This visualization is needed to observe the stability and  effectiveness of its mathematic model and control design. Experimental results and analysis show that control design and interface system can be implemented well.
