repositor.io is a tool for creating and managing Linux repositories. It can mirror online repositories so that you don't need to download packages every time you set up a new server, and it makes it easy to create custom repositories for your own packages. With the integration of a configuration management tool, you can create consistent installations on your servers.
Rerun is a lightweight tool-building framework useful to those implementing management procedure with shell scripts. It will help you organize your implementation into well-defined modular interfaces. Collections of management modules can be archived and delivered as a single executable to facilitate team handoffs. Using the "stubbs" module, rerun will even facilitate unit tests. When users execute rerun module commands, rerun can record execution data into log files which can later be replayed.
rtorstat is a simple Web page generator that shows status information about the rTorrent bittorrent client. This makes it possible to quickly have an overview of your torrent list from a remote location without having to log into the remote machine that actually runs rTorrent. It can be run through cron or as a CGI script.
Sardine is a next generation WebDAV client for Java. It is intended to be simple to use and does not implement the full WebDAV client spec. Instead, the goal is to provide methods for most use case scenarios when working with a WebDAV server. The code needs to run as fast as possible and use the latest released Apache HttpComponents.
Simple simeng (simple simulation engine) is a bare bones Java-based discrete simulation engine that uses variable time steps. Events are inserted in an ordered queue, and time is advanced based on the time the next event needs to be executed instead of discrete predefined timesteps. Entities can send events directly to other entities (one-2-one), or events can be broadcast to subscribed entities (one-2-many). The simplicity of the engine makes it suitable for educational purposes.
