apl

Aaron Hsu discusses design patterns and anti-patterns in APL and why the language is productive despite its write-only reputation. He argues that idioms matter more than libraries in array languages.

Aaron Hsu explains why programmers often find APL harder to learn than people with no programming background. He identifies eight patterns that contrast traditional software engineering practice with APL practice, starting from Ken Iverson's language design principles.

A JuliaCon 2016 talk by Shashi Gowda showing an APL implementation in Julia. APL code is translated to Julia and JIT compiled to machine code.

Evan Czaplicki, creator of Elm, examines how programming languages are funded. He looks at where compiler engineers' salaries come from, why Go has about 5 engineers while Dart has about 30, and how this limits language design.

Elm creator Evan Czaplicki's talk on how a file grows and when to split code up. He argues for keeping code in one file until it hurts and warns against premature extraction.

Aaron Hsu's FnConf18 talk asks whether APL needs a static type system. He argues that APL's expressiveness and rapid iteration already deliver the benefits usually credited to types.

Aaron Hsu shows how to manipulate and transform tree data in APL using arrays and inverted tables instead of pointers. He claims much smaller code, better performance and easier parallelisation.

Evan Czaplicki, creator of Elm, gives an elm-conf 2016 talk on the non-code side of building a language. It covers the philosophy behind Elm's development approach, including batching work and the priorities of different language communities.

Evan Czaplicki, creator of Elm, discusses the hard parts of running an open source project: online community conflict, why its patterns arise, and a cultural history of open source. He offers ideas for more civil, productive communication.

Evan Czaplicki, creator of Elm, talks at Curry On 2015 about user-focused language design. He explains the principles behind Elm and how to make a functional, typed language as approachable as JavaScript.

Evan Czaplicki's Strange Loop 2014 talk surveys the many formulations of functional reactive programming and how they relate historically and theoretically. It then shows how Elm's variant enables hot-swapping and its time-traveling debugger.

Elm creator Evan Czaplicki's 2018 Elm Europe talk on how to define success for an open source project and language community. It argues against judging projects by GitHub activity and touches on community expectations.

A two-hour live stream in which Aaron Hsu explains the architecture, design history and aesthetic of Co-dfns, his parallel APL compiler. He walks through the code and the reasoning behind its dense style.

Joshua Bloch's Google Tech Talk on how to design good APIs and why it matters, with concrete principles and examples. It treats every programmer as an occasional API designer.

Alan Kay's 2009 UIUC talk arguing that computing is more a pop culture than a science and that ignoring history and fundamentals leads to inferior solutions. He touches on the history of interactive environments and what the web should have been.

Steven Wittens' JSConf US 2013 talk on drawing with WebGL, using animated visuals to walk through vectors, matrices and the rendering pipeline. Despite the title, it works as a visual primer on the linear algebra behind 3D graphics.

Paul Graham speaks at Startup School 2008 about how to create a successful startup. His talk emphasizes being good, not just avoiding being evil, as a strategic advantage.

Kyle Drake of Neocities explains the bandwidth pricing pitfalls of the big cloud providers. He describes how to run high-volume, bandwidth-heavy infrastructure far more cheaply, including through co-location.

A joint Erlang Factory 2016 keynote by Phoenix creator Chris McCord and Elm creator Evan Czaplicki on using the two together, including Phoenix.Presence design and PubSub optimizations.
