The pure::variants Eclipse plugin supports development and variant management for software product lines with many product variants. pure::variants is completely model-based. It uses feature models for variability and commonality modeling. It supports creation, management, and evaluation of all necessary models, and uses XML based data formats. It includes a model transformer, which permits the creation of product variants directly from customizable components.
pyHIDS is a host-based intrusion detection system. It uses an RSA signature to check the integrity of its database. Alerts are written in the logs of the system, and can be sent via email to a list of users or on IRC channels (through the irker IRC client). You can define rules to specify files to be checked periodically.
pyOBD is an OBD-II compliant car diagnostic tool. It is designed to interface with low-cost ELM 32x OBD-II diagnostic interfaces such as ELM-USB. It will basically allow you to talk to your car's ECU, display fault codes, display measured values, read status tests, etc. All cars made since 1996 (in the US) or 2001 (in the EU) must be OBD-II compliant, i.e. they should work with pyOBD.
pyReScene is a tool that recreates original RARs by backing up the metadata. It is a port of ReScene .NET to Python. It provides a mechanism for backing up and restoring the metadata from "scene" released RAR files. RAR archive volumes are rebuilt using the stored metadata in the SRR file and the files extracted from the RAR archive. pyReScene consists of multiple related tools: pyReScene Auto to create a complete SRR with one simple command, pyReSample to recreate sample files, and pyReScene Usenet to create SRR files on the fly from Usenet postings. Lots of other small scripts for managing SRR and SRS files are available too.
