This is a short list of open-source projects I have published. Some haven't seen updates in quite some time, but all were used in research and/or production at some point and should remain usable.
Luffer is a tool to create isolated environments for software development and execution. Containers are seamlessly integrated to the host environment as they are instantiated, making possible to keep project files and general-purpose applications (such as text editor and version control clients) on the host, while project-specific tools and files are stored in the image. Multiple development environments with otherwise conflicting dependencies can therefore coexist in the same host.
CV Video integrates OpenCV's video recording and replaying API's to ROS.
PySHed simplifies access to shell commands and command-line applications from within Python scripts.
The rostweet package provides a bridge between ROS nodes and the Twitter microblogging service.
Terminal I/O enables ROS nodes to communicate with external terminal sessions.
