Mind Boggling Performance - Brian Becker
In our latest blog post – www.dyalog.com/blog/2026/03... – Brian investigates the effect that data structure can have on performance and optimisation by revisiting a challenge from the 2019 APL Problem Solving Competition. #Dyalog #APL #ArrayProgramming #Performance

The ArrayCast is back and now it's broadcast live! Join Conor Hoekstra, Adám Brudzewsky, and guests. The next episode, "FIXAPL with Jacob Lockwood", will take place on Monday 16 February at 15:00 UTC – see www.youtube.com/@arraycast/ #APL #ArrayProgramming #ArrayCast
I implemented org-babel support for 3 array languages I like a lot: Goal¹, BQN² and growler/k³. These languages are great for data munging so I find it very handy to use them in #OrgMode to process data stored in org tables. You can grab my implementations from my Emacs configuration at […]
Outperforming Nested Arrays with Classic APL Techniques – Part 1 / Asher Harvey-Smith
In our latest blog post – www.dyalog.com/blog/2026/01... – Asher explores the performance implications of choosing a flat representation rather than a nested one for your data.

And a very special thanks to @codereport.bsky.social for introducing me to this paradigm in the first place. Not sure how many people end up in the ADSP -> ArrayCast -> Dyalog conference pipeline, but I highly recommend it

HN discussed Klong, a simple array language. Debate centered on its terseness vs. readability, the array paradigm shift, and comparison to tools like NumPy. Is conciseness worth the learning curve for specific problems? 🤔 #ArrayProgramming 1/6
What does the following monadic mathematical function compute when given any numeric argument? (=∘⌊⍨*∘0.5) V20.0 will also support: (⌊⍛=*∘0.5)

A black 3.5-inch floppy disk with a silver metal shutter and a white label. The label has handwritten text reading “Dyalog v1.0 (April '83)” in black ink. The background is a gradient of orange and yellow tones with soft lighting and geometric shapes, giving the image a retro-tech aesthetic.
On this day in 1983, at the APL83 conference in Washington D.C., the world was introduced to Dyalog v1.0. Today we celebrate Dyalog reaching the milestone age that is the ultimate answer to Life, the Universe, and Everything! #Dyalog #APL #DontPanic #ArrayProgramming

This is an example of "Tacit Programming" in APL. The arguments are implied "tacitly" through function combinators, aka "Function Trains". If you see three functions in a row without arguments (⍺ being left arg, ⍵ being right), it's tacit.
Spoilers and breakdown below:
