Software maintenance is not like hardware maintenance, which is the return of the item to its original state. Software maintenance involves moving an item away from its original state. It encompasses all activities associated with the process of changing software. That includes everything associated with "bug fixes," functional and performance enhancements, providing backward compatibility, updating its algorithm, covering up hardware errors, creating user-interface access methods, and other cosmetic changes.

In software, adding a six-lane automobile expressway to a railroad bridge is considered maintenance—and it would be particularly valuable if you could do it without stopping the train traffic.

Is it possible to design software so it can be maintained in this way? Yes, it is. So, why don't we?

AbiCollab.net is a collaboration service based around the free AbiWord word processor. It allows you to write documents together with your friends in real time.

Heechee is a transparent mercurial-as-subversion gateway. It serves a Mercurial repository as a Subversion WebDAV-based repository. It's still in the early stages, but at the moment it will serve its own mercurial repository to subversion in such a way that you can check out the repository, and update to various revisions within it.

This is also known in the vernacular as "second save loses". It may sound too harsh, but it is much better than "first save loses and user isn't notified", which is what you get if you have no currency checking at all. And it's also much more web friendly that your old desktop app (which uses an approach that is technically called "pessimistic locking").

svk is a decentralized version control system built with the robust Subversion filesystem. It supports repository mirroring, disconnected operation, history-sensitive merging, and integrates with other version control systems, as well as popular visual merge tools.

CVSDude makes web-based collaboration easy and affordable. Customers benefit from secure multi-site access to popular version control solutions, wiki, and bug-tracking software, including Subversion, CVS, Trac, and Bugzilla.

I needed install Apache2 + Subversion and i have searching for info, etc. and now i'm decide to create this tutorial, i hope you like!

This howto outlines the process by which one can set up the Subversion version control system, and have it work in tandem with Trac, the project manager for software development projects, on a server running Ubuntu (or possibly Debian).

Moving a subversion repository from one server to another, while still preserving all your version history may seam like a daunting task, but fortunately it's not too difficult.
