mutest is a micro unit testing framework for C (with some C++ support). It is easy to use and has no dependencies. The idea is simple: a source file is a test suite, and a function is a test case (special functions can be used for test suite initialization and termination) that can can have several checks. Checks comes in 2 flavors: one that only prints an error, and one that terminates the current test case too. A (normally) automated test program run all the test suites and prints some stats. It fails (returns non-zero) if any test suite fails.
rstash is a server and client for transferring files over a network into file drop boxes on the server. It is primarily aimed at transferring things such as backup files from one host to another without opening up complete shell accounts, NFS, FTP, or other full file transfer mechanisms. The server has a set of boxes into which the client can put named files in a write-only fashion. No access to any portions of the server's file system outside the configured drop boxes is permitted.
