Attic is a deduplicating backup program. The main goal of attic is to provide an efficient and secure way to back up data. The data deduplication technique used makes Attic suitable for daily backups since only actual changes are stored. Main features: space efficient storage, optional data encryption, and off-site backups.
libnode is a C++ implementation of Node.js. Just like Node.js, libnode provides non-blocking I/O, which enables you to develop scalable Web applications in C++. The memory management of libnode is automatic, based on either shared_ptr or bdw-gc. libnode is good to use on embedded devices because its system resource consumption is lower than Node.js.
While the OSS community converges to Git, with the Python bunch branching to Mercurial, the typical workplace is stuck with Subversion. The author's DVCS of choice is Fossil. These are all fine projects, with their own pros and cons, but what you usually want is just a tool to store your code tree snapshot in a safe place. They can all do that, but their language differs a tiny bit. repo brings them all down to the common root. It works by detecting which VCS are you using right now and calling that, applying necessary subcommand translation if needed.
