Version control

In software engineering, version control (also known as revision control, source control, or source code management) is a class of systems responsible for managing changes to computer programs, documents, large web sites, or other collections of information. Version control is a component of software configuration management. Changes are usually identified by a number or letter code, termed the "revision number", "revision level", or simply "revision". For example, an initial set of files is "revision 1". When the first change is made, the resulting set is "revision 2", and so on. Each revision is associated with a timestamp and the person making the change. Revisions can be compared, restored, and, with some types of files, merged. The need for a logical way to organize and control revisions has existed for almost as long as writing has existed, but revision control became much more important, and complicated, when the era of computing began.

A semi-automated workflow paradigm for the distributed creation and curation of expert annotations

Johannes Hentschel, Fabian Claude Moss, Markus Franz Josef Neuwirth, Martin Alois Rohrmeier

The creation and curation of labeled datasets can be an arduous, expensive, and time-consuming task. We introduce a workflow paradigm for remote consensus-building between expert annotators, while considerably reducing the associated administrative overhead through automation. Most music annotation tasks rely heavily on human interpretation and therefore defy the concept of an objective and indisputable ground truth. Thus, our paradigm invites and documents inter-annotator controversy based on a transparent set of analytical criteria, and aims at putting forth the consensual solutions emerging from such deliberations. The workflow that we suggest traces the entire genesis of annotation data, including the relevant discussions between annotators, reviewers, and curators. It adopts a well-proven pattern from collaborative software development, namely distributed version control, and allows for the automation of repetitive maintenance tasks, such as validity checks, message dispatch, or updates of meta- and paradata. To demonstrate the workflow's effectiveness, we introduce one possible implementation through GitHub Actions and showcase its success in creating cadence, phrase, and harmony annotations for a corpus of 36 trio sonatas by Arcangelo Corelli. Both code and annotated scores are freely available and the implementation can be readily used in and adapted for other MIR projects.

Integrating Defect Data, Code Review Data, and Version Control Data for Defect Analysis and Prediction

Tao-Chun Lee

In this thesis, we present a new approach to integrating software system defect data: Defect reports, code reviews and code commits. We propose to infer defect types by keywords. We index defect reports into groups by the keywords found in the descriptions of those reports, and study the properties of each group by leveraging code reviews and code commits. Our approach is more scalable than previous studies that consider defects classified by manual inspections, because indexing is automatic and can be applied uniformly to large defect dataset. Also our approach can analyze defects from programming errors, performance issues, high-level design to user interface, a more comprehensive variety than previous studies using static program analysis. By applying our approach to Honeywell Automation and Control Solutions (ACS) projects, with roughly 700 defects, we found that some defect types could be five times more than other defect types, which gave clues to the dominant root causes of the defects. We found certain defect types clustered in certain source files. We found that 20%-50% of the files usually contained more than 80% of the defects. Finally, we applied a known defect prediction algorithm to predict the hot files of the defects for the defect types of interest. We achieved defect hit rate 50%-90%.

Interactive design exploration for constrained meshes

Sofien Bouaziz, Bailin Deng, Mario Moacir Deuss, Alexandre Kaspar, Mark Pauly, Yuliy Schwartzburg

In architectural design, surface shapes are commonly subject to geometric constraints imposed by material, fabrication or assembly. Rationalization algorithms can convert a freeform design into a form feasible for production, but often require design modifications that might not comply with the design intent. In addition, they only offer limited support for exploring alternative feasible shapes, due to the high complexity of the optimization algorithm. We address these shortcomings and present a computational framework for interactive shape exploration of discrete geometric structures in the context of freeform architectural design. Our method is formulated as a mesh optimization subject to shape constraints. Our formulation can enforce soft constraints and hard constraints at the same time, and handles equality constraints and inequality constraints in a unified way. We propose a novel numerical solver that splits the optimization into a sequence of simple subproblems that can be solved efficiently and accurately. Based on this algorithm, we develop a system that allows the user to explore designs satisfying geometric constraints. Our system offers full control over the exploration process, by providing direct access to the specification of the design space. At the same time, the complexity of the underlying optimization is hidden from the user, who communicates with the system through intuitive interfaces.
