VisTrails is an open-source scientific workflow and provenance management system developed at the University of Utah that provides support for data exploration and visualization. Whereas workflows have been traditionally used to automate repetitive tasks, for applications that are exploratory in nature, such as simulations, data analysis and visualization, very little is repeated---change is the norm. As an engineer or scientist generates and evaluates hypotheses about data under study, a series of different, albeit related, workflows are created while a workflow is adjusted in an interactive process. VisTrails was designed to manage these rapidly-evolving workflows.

pgcli is a command line interface for PostgreSQL with auto-completion and syntax highlighting. It is also capable of pretty printing tabular data.

Project should be useful when you have to administer many computers distributed through different networks and connected via NAT. In most of cases you may just install miredo, gogoc or any other tunnel broker's software and these computers will be available via IPv6 addresses. BOSixNet includes the collection of tools for automatic updating the list of such hosts.

PgDBF converts XBase databases, particularly FoxPro tables with memo files, into a format that PostgreSQL can directly import. It has no dependencies other than standard Unix libraries.

The 1-Wire bus is a cheap low-speed bus for devices like weather sensors, access control, etc. It can be attached to your system via serial, USB, I2C, and other interfaces.
