From the webpage:
The history and evolution of the Unix operating system is made available as a revision management repository, covering the period from its inception in 1970 as a 2.5 thousand line kernel and 26 commands, to 2016 as a widely-used 27 million line system. The 1.1GB repository contains about half a million commits and more than two thousand merges. The repository employs Git system for its storage and is hosted on GitHub. It has been created by synthesizing with custom software 24 snapshots of systems developed at Bell Labs, the University of California at Berkeley, and the 386BSD team, two legacy repositories, and the modern repository of the open source FreeBSD system. In total, about one thousand individual contributors are identified, the early ones through primary research. The data set can be used for empirical research in software engineering, information systems, and software archaeology.
You can read more details about the contents, creation, and uses of this repository through this link.
Two repositories are associated with the project:
- unix-history-repo is a repository representing a reconstructed version of the Unix history, based on the currently available data. This repository will be often automatically regenerated from scratch, so this is not a place to make contributions. To ensure replicability its users are encouraged to fork it or archive it.
- unix-history-make is a repository containing code and metadata used to build the above repository. Contributions to this repository are welcomed.
Not everyone will find this exciting but this rocks as a resource for:
empirical research in software engineering, information systems, and software archaeology
Need to think seriously about putting this on a low-end laptop and sealing it up in a Faraday cage.
Just in case. 😉
