The APL Quest Series
It seemed like a normal Friday until mid-afternoon. But on 4 February 2022, I embarked on a journey that, at the time, seemed to stretch impossibly far into the future — a future that wasn’t entirely known yet. In the APL Orchard chat room on Stack Exchange, a dozen APLers, some experts and some newbies, […]

Whether you are celebrating a winter holiday, looking forward to the days getting longer from tomorrow, or enjoying summer south of the equator, we hope you have time to enjoy the final collection of light-hearted presentations from Dyalog ’23.

Dyalog ’23 Videos: Week 7 – Performance and Scaling
Although run-time performance is rarely the most important reason for selecting APL, good performance often becomes important during the lifetime of an application (especially if it is successful and, therefore, has to deal with growing data volumes and numbers of users). Array-oriented programming naturally encourages Subject Matter Experts to use dense and pointer-free structures, which […]
Dyalog ’23 Videos: Week 6 – Tools and Services
An increasing number of APL systems serve business logic as services, in addition to providing a user interface. Some recent APL applications have no user interface at all, and are only available as services. For this reason, Dyalog’s web service framework, Jarvis, features prominently in Brian Becker’s overview of the current state of tool development […]
Dyalog ’23 Videos: Week 5 – Tools and Interfaces
This week, the focus is on the use of tools and interfaces in applications. Mark Wolfson from BIG integrates data from 1,000 retailers to provide business intelligence to both the retailers and manufacturers. Over the last couple of years, Mark has migrated his application from IBM APL2 to Dyalog APL. He tells the story of […]
Dyalog ’23 Videos: Week 4 – Research and Education
I am always thrilled to hear from people who have been able to use APL to gain insight into difficult subjects, or use APL to pass knowledge on to others. A truly fascinating and surprising example of this at Dyalog ’23 was the talk titled “quAPL – A Quantum Computing Library in APL”, in which […]
Dyalog ’23 Videos: Week 3 – Dyalog Core Development
This week’s collection consists of presentations by members of the development team, and concentrates on language features and development tools that the developers are currently designing or already implementing. Many of these features are likely to be in version 20.0 of Dyalog, which we plan to release in early 2025, about a year after version […]
Dyalog '23 Videos: Week 2 – APL Problem Solving Competition
The section that is dedicated to the annual APL Problem Solving Competition is always one of my own favourite parts of a Dyalog user meeting, and the talks by the two winners this year were no exception. It is always a treat to hear about how the student winners are able to go from zero […]
Welcome to the Dyalog '23 Videos!
Welcome to the 2023 edition of the Dyalog user meeting presentation recordings. This year, we plan to release a few talks each week until the Winter Solstice – and I will be doing my best to introduce each block of related talks. Week 1 – A New CEO! For the 19th year running, the annual […]
