The comments revolve around the merits of SCCS (Source Code Control System) versus modern version control systems such as Git. Several users express appreciation for SCCS, particularly its efficiency in accessing file versions and preserving authorship. They discuss the differences between SCCS's 'weave' format and Git's patch-based system, pointing out that both allow for constant-time access to file versions, albeit with different underlying mechanisms. Users share personal experiences with SCCS, including its continued use in certain firms and challenges faced in transitioning to newer systems like Git. There is also mention of the history of version control systems and the evolution from SCCS to Git. Notably, Larry McVoy, creator of BitKeeper, is discussed in relation to the development of Git and its impact on modern version control practices. The conversation highlights both the nostalgia for older systems and the practical considerations in assessing their features compared to contemporary alternatives.
