Morten Kromberg / Speaker at DYNA26 / New York City
Morten has been Dyalog's CTO since 2005, drawing on 25 years of APL expertise to guide technical direction and support APL migration.
DYNA26#APLQuest 2015-06: Write a function that takes, as each of its right and left arguments, a pair of co-ordinates representing diagonally opposite corners of two rectangles and returns a 1 if the rectangles overlap (see https://apl.quest/2015/6/ to test your solution and view ours).

APL Quest 2015-6: Hey! This is My Space
Write a function that takes, as each of its right and left arguments, a pair of co-ordinates representing diagonally opposite corners of two rectangles and returns a `1` if the rectangles overlap.
The programme for DYNA26 is now available at https://dyna.dyalog.com/programme/. This free, one-day, in-person event for existing and potential users of Dyalog will take place on Monday 27 April 2026 in New York City. Spaces are limited, and these events usually fill up quickly, so register now to reserve your place. For more information and to register, see https://dyna.dyalog.com/

Episode 122: REPL & IDE Deep Dive
YouTubeIn our latest blog post – https://www.dyalog.com/blog/2026/03/mind-boggling-performance/ – Brian investigates the effect that data structure can have on performance and optimisation by revisiting a challenge from the 2019 APL Problem Solving Competition.

APL Quest 2015-4: PDI - Progressive Dyadic Iota
Write a function that implements progressive dyadic iota.
If you are in the Toronto, Canada, area on Thursday 12 March, why not spend the afternoon (15:45-17:30 EDT ) at a panel discussion on the history of academic computing in Canada? Hosted by York University, APL is likely to feature – their “York APL” implementation helped spread APL’s academic use in the 1970s. Reserve your place at

APL Quest 2015-3: Farey Tale
Write a function that takes an integer right argument and returns a vector of the terms in the Farey sequence of that order.
Topics covered will include highlights of Dyalog v20.0 (and maybe a sneak preview of what to expect in Dyalog v21.0), a demonstration of tools for migrating to Dyalog APL from other APL implementations, and an update on Dyalog’s interfaces with AI.
