Paint your programs green: on the energy efficiency of data structures
Pereira, Rui Alexandre Afonso; Couto, Marco; Cunha, Jácome; Melfe, Gilberto; Saraiva, João; Fernandes, João PauloThis tutorial aims to provide knowledge on a different facet of efficiency in data structures: energy efficiency. As many recent studies have shown, the main roadblock in regards to energy efficient software development are the misconceptions and heavy lack of support and knowledge, for energy-aware development, that programmers have. Thus, this tutorial aims at helping provide programmers more knowledge pertai...
Impact of remote work on Portuguese software professionals during the COVID-19 ...
Almeida, Ana J.; Cunha, Jácome; Fernandes, João M.Although remote work was already possible and used in some contexts, the COVID-19 pandemic made it normal and, in some situations, even mandatory. This was the case in Portugal and in particular in its software industry. Given this abrupt change in how we work, it became pressing to investigate the impacts of this profound change to remote work, so that we can cope with the potential negative consequences (prof...
Identification of microservices from monolithic applications through topic mode...
Brito, Miguel; Cunha, Jácome; Saraiva, JoãoMicroservices emerged as one of the most popular architectural patterns in the recent years given the increased need to scale, grow and flexibilize software projects accompanied by the growth in cloud computing and DevOps. Many software applications are being submitted to a process of migration from its monolithic architecture to a more modular, scalable and flexible architecture of microservices. This process ...
Ranking programming languages by energy efficiency
Pereira, Rui; Couto, Marco; Ribeiro, Francisco; Rua, Rui António Ramada; Cunha, Jácome; Fernandes, João Paulo; Saraiva, JoãoThis paper compares a large set of programming languages regarding their efficiency, including from an energetic point-of-view. Indeed, we seek to establish and analyze different rankings for programming languages based on their energy efficiency. The goal of being able to rank programming languages based on their energy efficiency is both recent, and certainly deserves further studies. We have taken rigorous a...
Ranking programming languages by energy efficiency
Pereira, Rui Alexandre Afonso; Couto, Marco; Ribeiro, Francisco José Torres; Rua, Rui António Ramada; Cunha, JácomeThis paper compares a large set of programming languages regarding their efficiency, including from an energetic point-of-view. Indeed, we seek to establish and analyze different rankings for programming languages based on their energy efficiency. The goal of being able to rank languages with energy in mind is a recent one, and certainly deserves further studies. We have taken 19 solutions to well defined progr...
Data curation: towards a tool for all
Dias, José; Cunha, Jácome; Pereira, RuiData science has started to become one of the most important skills one can have in the modern world, due to data taking an increasingly meaningful role in our lives. The accessibility of data science is however limited, requiring complicated software or programming knowledge. Both can be challenging and hard to master, even for the simple tasks. With this in mind, we have approached this issue by providing a n...
On understanding data scientists
Pereira, Paula; Cunha, Jácome; Fernandes, João PauloData is everywhere and in everything we do. While,on its own, data has little value, its analysis under the lenses ofdata science currently supports extremely valuable functions andsystems. In recent years, the need to obtain knowledge from hugeamounts of data lead companies to hire many professionals ableto work creatively on data for data science position, regardlessof their academic and professional backgrou...
SPELLing out energy leaks: Aiding developers locate energy inefficient code
Pereira, Rui Alexandre Afonso; Carção, Tiago Alves; Couto, Marco Domingos Mendes; Cunha, Jácome; Fernandes, João Paulo; Saraiva, JoãoAlthough hardware is generally seen as the main culprit for a computer's energy usage, software too has a tremendous impact on the energy spent. Unfortunately, there is still not enough support for software developers so they can make their code more energy-aware.This paper proposes a technique to detect energy inefficient fragments in the source code of a software system. Test cases are executed to obtain ener...
Get your spreadsheets under (version) control
Macedo, José Nuno; Moreira, Ricardo; Cunha, Jácome; Saraiva, JoãoSpreadsheets play a pivotal role in many organizations. They serve to store and manipulate data or forecasting, and they are often used to help in the decision process, thus directly impacting the success, or not, of organizations. As the research community already realized, spreadsheets tend to have the same problems “professional” software contain. Thus, in the past decade many software engineering techniques...
Towards using memoization for saving energy in android
Rua, Rui; Couto, Marco Domingos Mendes; Pinto, Adriano; Cunha, Jácome; Saraiva, JoãoOver the last few years, the interest in the analysis of the energy consumption of Android applications has been increasing significantly. Indeed, there are a considerable number of studies which aim at analyzing the energy consumption in the Android ecosystem, such as measuring/estimating the energy consumed by an application or block of code, or even detecting energy expensive coding patterns or APIs. In this...
