Learn about Lore: next-generation open source version control

Lore is a next-generation, open source revision control system

The Lore Version Control System - Lore Developer Documentation

A reference document explaining the rationale, goals, and theoretical design of Lore. This is not a peer-reviewed paper; it is a public-facing standalone description of the system, intended to make the why of Lore - the problems it was built to solve and the design choices that follow from those problems - as legible as a reader can make it without reading the source code.

Universal Version Control

Building tools to help people explore alternatives, keep track of history, and collaborate better, across all kinds of media.

Open-source version control system for Data Science and Machine Learning projects. Git-like experience to organize your data, models, and experiments.

Between Principle and Pragmatism: Reflections on Prototyping Computational Media with Webstrates

Computational media describes a vision of software, which, in contrast to application-centric software, is (1) malleable, so users can modify existing functionality, (2) computable, so users can run custom code, (3) distributable, so users can open documents across different devices, and (4) shareable, so users can easily share and collaborate on documents. Over the last ten years, the Webstrates and Codestrates projects aimed at realizing this vision of computational media. Webstrates is a server application that synchronizes the DOM of websites. Codestrates builds on top of Webstrates and adds an authoring environment, which blurs the use and development of applications. Grounded in a chronology of the development of Webstrates and Codestrates, we present eight tensions that we needed to balance during their development. We use these tensions as an analytical lens in three case studies and a game challenge in which participants created games using Codestrates. We discuss the results of the game challenge based on these tensions and present key takeaways for six of them. Finally, we present six lessons learned from our endeavor to realize the vision of computational media, demonstrating the balancing act of weighing the vision against the pragmatics of implementing a working system.

Reflections: The ecosystem is moving

At Open Whisper Systems, we’ve been developing open source “consumer-facing” software for the past four years. We want to share some of the things we’ve learned while doing it. As a software developer, I envy writers, musicians, and filmmakers. Unlike software, when they create something, it is...

Doing Data Science on the Shoulders of Giants: The Value of Open Source Software for the Data Science Community

Open source software is ubiquitous throughout data science, and enables the work of nearly every data scientist in some way or another. Open source projects, however, are disproportionately maintained by a small number of individuals, some of whom are institutionally supported, but many of whom do this maintenance on a purely volunteer basis. The health of the data science ecosystem depends on the support of open source projects, on an individual and institutional level.
