Tooling

Data tools

• VisiData - Terminal user interface for a data exploration/manipulation tool that can handle large datasets.
• qsv - "command line program for indexing, slicing, analyzing, splitting, enriching, validating & joining CSV files. Commands are simple, fast and composable." Forked from xsv by CKAN Joel, so it's got some CKAN-specific features in the works.

Anonymization

• Open Diffix - Free, open-source desktop tool (and eventually Postgres extension) for anonymizing data.
