GTD-Free is personal todo/action manager inspired by the GTD (Getting Things Done) method by David Allen. It tries to be a simple and easy to use management tool. It aims to guide users to manage very efficient GTD workflow even if they are not familiar with GTD or are too unorganized to follow it. The user interface is clean and simple at each step of the workflow: the user objective should be to get things done and spend a minimum of time with the tool itself.
Curie is a very minimalistic, tiny C library. It supports basic I/O, basic networking, S-expression based I/O, signal handling, process handling, and I/O multiplexing. If the target architecture is explicitly supported, statically linked binaries may be as small as 4-20 kilobytes; if not, then it only relies on the host's C library. The library explicitly does not provide a POSIX interface so that it may be used in conjunction with a regular host libc (or without one).

Integration to existing authentication mechanisms provided by Web portals or other SSO systems is also possible.
