Large-scale paper-based examinations (PBEs) in computing education frequently emphasize rote memorization, thereby misaligning instructional objectives with assessment techniques. Such incongruities hinder the preparation of students for real world ...

The Abstract Syntax Tree (AST) serves as a pivotal representation of program codes, offering a structured and hierarchical view of the program’s syntax. When developers modify code, the underlying AST also evolves to reflect these changes. Tree-diff ...

Besides referring to digital twins, the iterative development of physical objects cannot be easily managed in version control systems. However, physical content also could benefit from versioning for structured work and collaborative uses, thereby ...

Bridges-2 is an NSF-funded heterogeneous supercomputing cluster at the Pittsburgh Supercomputing Center. The successor to the Bridges system (2014-2021), Bridges-2 builds on the flexibility demonstrated by its predecessor to support a wide variety of ...

In iterative physical object creation, only the latest design state is manifested in the physical artifact, while information about previous versions are lost. This makes it challenging to keep track of changes and developments in iterative physical ...

Merge conflicts are very common in collaborative software development. Such collaborative work is usually supported by the use of branches, which at some point can be merged. In the technical literature, several studies propose mechanisms to avoid ...

Programming geo-replicated distributed systems is challenging given the complexity of reasoning about different evolving states on different replicas. Existing approaches to this problem impose significant burden on application developers to consider the ...

Effectively computing the difference between two version of a source file has become an indispensable part of software development. The de facto standard tool used by most version control systems is the UNIX diff utility, that compares two files on a ...

In this paper, we propose a blockchain-based solution and framework for document sharing and version control to facilitate multi-user collaboration and track changes in a trusted, secure, and decentralized manner, with no involvement of a ...

Version control is an integral part of teamwork in software development. Differencing and merging key artifacts (i.e. source code) is a key feature in version control systems. The concept of version control can also be applied to model-driven ...

Diffing and merging of source-code artifacts is an essential task when integrating changes in software versions. While state-of-the-art line-based tools (e.g., git merge) are fast and independent of the programming language used, they have only a low ...

The Unix diff utility that compares lines of text is used pervasively by version control systems. Yet certain changes to a program may be difficult to describe accurately in terms of modifications to individual lines of code. As a result, observing ...

Model-driven software product line engineering is complicated: In addition to defining a variability model,

developers must deal with a multi-variant domain model. To reduce complexity, filtered editing, inspired by

version control, was recently ...

Software development is typically a collaborative activity. Development in large projects often involves branches, where changes are performed in parallel and merged periodically. While, there is no consensus on who should perform the merge, team ...

Development in large projects often involves branches, where changes are performed in parallel and merged periodically. This merge process often combines two independent and long sequences of commits that may have been performed by multiple, different ...

Parallel development in branches is a common software practice. However, past work has found that integration of changes across branches is not easy, and often leads to failures. Thus far, there has been little work to recommend developers who have the ...

Surface computing encourages exploratory interaction, and many applications are designed to work this way. In essence, the fluid interaction causes the user to ask “What if?” We suggest this requires support for recording the history of such ...

The realm of knowledge discovery extends across several allied spheres today. It encompasses database management areas such as data warehousing and schema versioning; information retrieval areas such as Web semantics and topic detection; and core data ...

This paper analyzes two existing methods for securing Git repositories, Git-encrypt and Git-crypt, by comparing their performance relative to the default Git implementation. Securing a Git repository is necessary when the repository contains sensitive or ...

Distributed Version Control Systems (DVCS) have seen an increase in popularity relative to traditional Centralized Version Control Systems (CVCS). Yet we know little on whether developers are benefitting from the extra power of DVCS. Without such ...
