Camp QB

Milden Hall
Milden Hall

On the weekend of 6-7 October 2018 we held Camp QB.

This was 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

Camp QB taught a master class in the adverbs and in key primitive functions. Participants gained a deep understanding of the ‘big engines’ of kdb+, such as Apply, Index and Amend, and how they combine powerfully with the adverbs. We aimed for 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 had

  • two 8-bed dormitories in the new Milden Hall ‘bunkhouse’, one for women, one for men
  • half a dozen ‘sofas’ in the Tudor barn, from divans to four-poster beds
  • space for some campers

Bring your laptop and a sleeping bag.

The accommodation is open from Friday evening.
