ViTables is a GUI for PyTables. It allows to open, browse and query arbitrarely large PyTables and HDF5 files.

Note that ViTables is commercial software whereas PyTables is free software (BSD licensed).

This second video explains in depth how to quickly query multi-billion row tables using ViTables in combination with OPSI , the powerful indexing engine that comes with PyTablesPro, the commercial version of PyTables. The covered topics are:

  • how to do queries involving several fields a.k.a complex queries
  • how to include the indexes of the selected rows in a query result
  • detailed description of the queries dialog
  • how indexing fields with OPSI affects the speed of queries

It has a running length of about 8 minutes, so you can watch it during any short break.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for The
