The PConf Makefile skeleton system is a GNU Make based makefile skeleton that provides a makefile standard and a configure standard for C/C++ programs. It supports different operating systems (for makefiles), special config.h files for differens OSs, a config.h that mirrors all 'have_xyz' variables of the Makefile, the ability to include a config.h.in, more checks for more libraries, a "check only" mode for configuring libraries, and more.
CMME (Content Management Made Easy) is a Web content management system that aims to be easy to use, doesn't have many requirements, and is still reasonably flexible. It doesn't need a database, doesn't have extensive administrative needs, and works more or less like a wiki. New pages can be made on the fly, rather than through an administrative page.
PerlShare is a DropBox drop-in to create your own private file sharing "cloud". It consists of two parts; a client and a server. The server part lets you configure a Linux machine to accept PerlShare clients. PerlShare behaves a lot like DropBox. On collisions, for example, it creates conflicted copies. The workhorse for synchronization is Unison, a very reliable piece of software from Pascal Bach.
