    Children

    Development of a one month project with children in a poor zone of Ribeira Grande at Azores. The project consisted in creating a summer camp for children and teenagers in the area. We created a set of games and activities to challenge the kids to see outside of their comfort zone and dream of a better future for them and for their neighbourhood. This program was developed in parallel with a set of sessions for the children's parents.

  • Isolating Graphical Failure-Inducing Input for Error Report Anonymization

    Proceedings on Privacy Enhancing Technologies, De Gruyter Open

    This work proposes a new privacy-enhancing system that anonymizes the content of error reports. Error reporting mechanisms are of the utmost importance to correct software bugs but, unfortunately, the transmission of an error report may reveal users' private information. Some privacy-enhancing systems for error reporting have been presented in the past years, yet they rely on path condition analysis, which we show in this paper to be ineffective when it comes to anonymize graphical-based input.…

    This work proposes a new privacy-enhancing system that anonymizes the content of error reports. Error reporting mechanisms are of the utmost importance to correct software bugs but, unfortunately, the transmission of an error report may reveal users' private information. Some privacy-enhancing systems for error reporting have been presented in the past years, yet they rely on path condition analysis, which we show in this paper to be ineffective when it comes to anonymize graphical-based input. Knowing that numerous applications have graphical user interfaces (GUI), it is very important to overcome such limitation. This work describes a new privacy-enhancing error reporting system, based on a new input minimization algorithm called GUImin that is geared towards GUI, to remove (thereby anonymize) input that is unnecessary to reproduce the observed failure. Before deciding whether to submit the error report, the user is provided with a step-by-step graphical replay of the minimized input, to evaluate whether it still yields sensitive information. We also provide an open source implementation of the proposed system and evaluate it with well-known applications.

  • Record and Replay GUI-based Applications with Less Overhead

    RSDA | ISSRE 2014

    Debugging is, typically, a hard and time-consuming task. Fault-replication mechanisms facilitate the debugging process by providing software developers with the errors’ steps-to- reproduce. The main challenge of fault-replication is the overhead imposed by recording all non-deterministic events of an execution, such as thread interleaving and the user interaction with the application. The overhead imposed by user input is especially significant for graphical-based applications. This paper…

    Debugging is, typically, a hard and time-consuming task. Fault-replication mechanisms facilitate the debugging process by providing software developers with the errors’ steps-to- reproduce. The main challenge of fault-replication is the overhead imposed by recording all non-deterministic events of an execution, such as thread interleaving and the user interaction with the application. The overhead imposed by user input is especially significant for graphical-based applications. This paper proposes a new approach to record and replay the user interaction with the GUI, which significantly reduces the amount of information recorded. We developed an open-source implementation of an execution recording framework and evaluated it using a testbed that includes well-known publicly-available applications with real bugs. We achieved average reductions of 3567 times fewer events recorded. Keywords-Software Bugs; Error Reporting; Fault-Replication; GUI; Graphical; Input, Record and Replay.

    Development of a solution to play Youtube videos in the IRIS middleware. Implementation of a prototype to prove the technical solution convey the value to management. This solution was deployed in production in three apps: Youtube Search, Youtube Channels, and Youtube Related Videos. The first two ones deliver a fast and clean way to search and watch Youtube videos directly on the TV. Youtube Related integrates with a semantic enrichment engine in order to find related videos for EPG events…

This solution was deployed in production in three apps: Youtube Search, Youtube Channels, and Youtube Related Videos. The first two ones deliver a fast and clean way to search and watch Youtube videos directly on the TV. Youtube Related integrates with a semantic enrichment engine in order to find related videos for EPG events. This gives users the chance to quickly find trailers, documentaries, and interviews for TV events.

  • GAUDI: Graphical Anonymization of User Domain Input

    -

    Research and development of a new paradigm for bug report anonymization using deterministic replay techniques. The system enables developers to view a synthesised version of the error from the user point of view. This allows for the developer to quickly understand where the bug is instead of having to make sense of a memory dump or other similar mechanism. Moreover, it greatly improves the privacy of the user since all the steps that are not relevant to the bug are eliminated from the graphical…
