mylbhelper helps dumb load balancers do their job. It monitors a local MySQL instance by periodically issuing a query. Should the query fail, a custom script, which typically would firewall off the load balancer, is executed. Likewise, when it comes back up, another script is executed. This means you can use any load balancer capable of distributing TCP traffic rather than one natively capable of talking MySQL. mylbhelper can also act solely as a monitoring daemon.
Teractualizar is a daemon to synchronize files using SFTP as a secure transfer method. It also features the ability to upload and execute any application or command, which can be used to manage clusters of computers. It requires only baaic Unix commands, an SSH client, and the SFTP service. Currently, the client side of this system only runs on Windows NT (and derivative operating systems).
Urpkg is software to install programs in a safe and undoable way. It is able to see what files any given installation command creates, and list and remove them. You are able to restrict the installation command so that it only writes where you allow it to, and does not overwrite files from other packages. Urpkg is especially useful if you want to install programs from source, or create binary packages in an automated way. Under the hood, urpkg creates a user for each package it has to install, which prevents the installation command from run with root privileges. It can be seen as a "command tracer" that remembers what files a command created and prevents it from doing forbidden things. It is written in C but relies on some external commands, like GNU Find.
Werc is a minimalistic RESTful Web application framework and content management system. It follows the Unix "tool philosophy" and it is designed to be fast, simple, convenient, and easily extensible. It handles both small and big sites and has a flexible system for user and group permissions. All data is stored in plain text files that can be easily manipulated with standard tools, without using any databases or other external dependencies. Existing applications include a blogging engine with RSS/Atom feeds, a wiki system that can easily integrate pre-existing documents (can be enabled for any directory tree), and others.
