pattern recognition

Alex Martelli's Google Developers Day talk on classic design patterns (creational, structural and behavioral) and how they appear in Python. He stresses that patterns must be studied in the context of the implementing language.

Stuart Halloway's satirical talk describes how to protect yourself from industry change by spreading complexity through systems while following idiomatic practice. It uses this inversion to catalog software design anti-patterns.

Bryan Cantrill's talk on corporate open source anti-patterns, first given at FISL 2012 and again at the Liferay Symposium. He lays out the mistakes companies make when open sourcing code, such as announcing future open sourcing, and discusses licenses.

A HOPE XI talk on programming by voice with open source speech recognition. The speaker writes Linux systems code by voice and describes building custom voice grammars as an alternative to the keyboard for programmers with repetitive strain injuries.

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.

Mathematician Colin Wright demonstrates juggling and explains the mathematics of juggling patterns, including notation that led to new throwing patterns. It is a public presentation at the Museum of Mathematics aimed at a general audience.

Emily Shea explains how repetitive strain injury pushed her to program by voice using speech recognition (Talon), and gives a live coding demo. She argues voice-driven development can be pain-free, efficient and enjoyable.

A clip from the movie Minority Report showing personalized advertising that recognizes a person as they walk through a mall.

Scott Wlaschin demystifies functional programming terms like monads, monoids, functors and catamorphisms by showing how they fit into a small toolkit. He applies them to problems such as missing data, list handling, and functional dependency injection.

Ashley Feniello demonstrates VimSpeak, a voice-controlled interface for Vim inspired by Tavis Rudd's voice programming talk. The demo includes working through a VimGolf challenge by speech.

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.

A JSConf 2014 talk visually breaking down algorithms behind everyday UI patterns, such as dropdown menus that vanish when the mouse drifts and picking the nearest target to the cursor. It shows how these are implemented in JavaScript.

Douglas Crockford's Nordic.js 2014 talk on 'the better parts' of JavaScript and programming in general. He argues against `this`, `new` and ES6 classes, and for classless, composition-based object patterns, with some broader remarks on building better structures for the future.

Michael Levin presents his lab's work on how cellular collectives use bioelectric networks to make anatomical decisions. Topics include pattern memories, regeneration and synthetic living organisms.

Johann Korndorfer's NVScene 2015 talk on building content with signed distance functions. It focuses on patterns that make SDF modelling more structured, arguing that SDFs capture a shape's essence like vector graphics do compared with polygons or voxels.

Huygens Optics shows how DIY photon sieves shape a laser's wave front, explaining how they differ from zone plates and how aperture count affects the focal point, with time-resolved visualizations of the diffraction.

Greg Wilson surveys what empirical research actually shows about software development, why we believe it, and how to share that knowledge more widely. It covers evidence on practices such as TDD and design patterns.

Sebastian Markbage explains how React is moving toward a minimal API surface by leaning on language features and patterns instead of dedicated framework APIs. He also touches on JSX and syntax proposals for future JavaScript.

Jon Gjengset spends about three hours livecoding complex changes in a Rust codebase with agentic AI tools, testing his hypothesis that AI is weak at non-pattern work. He documents where Claude Code helps and where it struggles.

Raymond Hettinger's PyBay 2019 talk on the mental strategies he uses when programming in Python, such as chunking, solving a simpler related problem, and repeating tasks manually until patterns emerge. This version is re-synced with the slides.

A 2006 Google TechTalk in which Luis von Ahn introduces human computation, using people's effort to solve problems like image recognition that computers cannot yet handle. It covers games with a purpose and related ideas such as CAPTCHAs.

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.
