Camp QB

Milden Hall
Milden Hall

On the weekend of 6-7 October we shall hold Camp QB.

This is an unprecedented opportunity for enthusiasts to engage with kdb+ at a deep level, in the company of the implementors and developers at Iverson College.

The masterclass

The revised q Reference material will be online by the time of the camp. This is V2.0, replacing and supplementing the material originally imported from the Kx Wiki. It will document the language formally and at a depth not attempted since the K Reference Manual of 1995.

Camp QB will teach a master class in the adverbs and in key primitive functions. Participants will gain a deep understanding of the ‘big engines’ of kdb+, such as Apply, Index and Amend, and how they combine powerfully with the adverbs. Expect sudden flashes of enlightenment – and personal moments of liberation from scalar thinking.


  • Geo Carncross, Kx Systems
  • Stephen Taylor, Kx Librarian
  • Attila Vrabecz, veteran kdb+ developer


We have

  • two 8-bed dormitories in the new Milden Hall ‘bunkhouse’, one for women, one for men
