Sendo o sistema operacional com maior presença entre os smartphones em todo o mundo, desenvolver aplicaçoes para o Android tem se tor- ˜ nado cada vez mais interessante. Entretanto, para tirar o melhor proveito desta plataforma e importante conhecer como ela funciona internamente. Este ar- ´ tigo aborda os principais componentes que fazem parte do software stack do Android, começando pelo kernel Linux e a Dalvik VM ate os componentes prin- ´ cipais de uma aplicaçao. E mostra as estrat ˜ egias adotadas pela plataforma ´ para lidar com caracter´ısticas inerentes aos dispositivos moveis, como o tempo ´ de bateria e a baixa capacidade de memoria.

Fóruns foram utilizados por muito tempo na Internet como principal ferramenta para criação de comunidades online e discussões sobre determinados assuntos. Com o surgimento das redes sociais, o foco de grande parte da Internet passou a ser o indivíduo e suas relações com outras pessoas. Com elas também foram introduzidas novas funcionalidades que melhoraram a experiência de seus usuários e possibilitaram uma melhor comunicação com outras pessoas. Este trabalho buscou unir algumas destas funcionalidades na tentativa de criar um fórum que se adequasse a realidade atual sem, entretanto perder as características básicas de um fórum. O serviço focou primeiramente dispositivos móveis, mantendo uma interface de usuário simples, reunindo todos os interesses em um único lugar e permitindo que usuários sigam interesses e filtrem conversas de acordo com a sua localização. Essas ações tornaram possível a criação de um fórum diferente e que pode ser útil e de fácil uso para as pessoas, mesmo com relação as redes sociais.

Recently a new application domain characterized by the continuous and low-latency processing of large volumes of data has been gaining attention. The growing number of applications of such genre has led to the creation of Stream Processing Systems (SPSs), systems that abstract the details of real-time applications from the developer. More recently, the ever increasing volumes of data to be processed gave rise to distributed SPSs. Currently there are in the market several distributed SPSs, however the existing benchmarks designed for the evaluation this kind of system covers only a few applications and workloads, while these systems have a much wider set of applications. In this work a benchmark for stream processing systems is proposed. Based on a survey of several papers with real-time and stream applications, the most used applications and areas were outlined, as well as the most used metrics in the performance evaluation of such applications. With these information the metrics of the benchmark were selected as well as a list of possible application to be part of the benchmark. Those passed through a workload characterization in order to select a diverse set of applications. To ease the evaluation of SPSs a framework was created with an API to generalize the application development and collect metrics, with the possibility of extending it to support other platforms in the future. To prove the usefulness of the benchmark, a subset of the applications were executed on Storm and Spark using the Azure Platform and the results have demonstrated the usefulness of the benchmark suite in comparing these systems.

Scaling API-first – The story of a global engineering organization

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
