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.

Rick Houlihan's AWS re:Invent 2018 deep dive on advanced DynamoDB design patterns. It covers index overloading, GSI sharding, composite keys, graph processing and transactions.

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.

Veritasium explains how Penrose tilings and quasicrystals overturned the belief that 5-fold symmetry and non-periodic crystals were impossible, including an interview with Paul Steinhardt.

The first lecture of Stanford's CS231n course on convolutional neural networks for visual recognition. It surveys the history and key challenges of computer vision, from the Cambrian explosion and Hubel and Wiesel to ImageNet.

An AWS re:Invent 2019 session for advanced DynamoDB users on design patterns used by large customers, including Amazon retail. It covers GSI sharding, index overloading, graph processing, composite keys and transactional workflows.

Rob Pike's Google I/O 2012 talk shows how goroutines and channels solve tricky concurrency problems with simple Go code. It features a playful goroutine demo with gophers passing messages and a search engine example.

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.

Bob Nystrom, author of Game Programming Patterns, gives a Roguelike Celebration 2018 talk questioning whether entity component systems are the only way to structure a game. He walks through alternative architectures drawn from roguelike development.

An episode of Patriot Act with Hasan Minhaj exposing how tax-prep companies like TurboTax make filing confusing and costly even though many Americans can file for free. It combines comedy with reporting on lobbying and dark patterns.

Paul Irish walks through the jQuery source code and shares ten lessons and interesting techniques from it, aimed at JavaScript developers who want to learn from a widely used library.

Martin Fowler's GOTO Chicago 2017 talk on the different things people mean by event-driven architecture. He identifies four patterns, including event notification and event-carried state transfer.

Kevlin Henney's GOTO 2018 talk argues that much of what looks new in software is a recycling of concepts with long histories. It draws on history to show the slow, steady current beneath constant churn in frameworks and trends.

Tavis Rudd describes how RSI forced him to program by voice, and shows the Python and Emacs Lisp system he built with voice recognition. A live demo creates and deploys a small system without touching the keyboard.

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.

Brandon Rhodes' PyOhio 2014 talk on applying the Clean Architecture in Python. He shows how this high-level design pattern fits Python's features and addresses maintainability problems in large applications.

3Blue1Brown explains why plotting primes in polar coordinates produces spiral patterns, using modular arithmetic, Dirichlet's theorem and rational approximations of pi.

Casey Muratori shows how typical 'clean code' object-oriented patterns can cost large factors in performance. He benchmarks them against simpler data-oriented code.

An excerpt of the 2005 Harvard debate in which Steven Pinker gives his prepared case on biological sex differences and the under-representation of women in science. It covers cross-cultural patterns in preferences and abilities and the overlap between male and female distributions.

Andrew Huang teaches the basics of music theory in about half an hour, covering intervals, chords and patterns. He stresses understanding how music works over memorizing terminology.

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.

Vsauce's explainer on Zipf's law, the pattern in which the frequency of a word is inversely related to its rank. It shows the pattern across many domains and discusses why it remains unexplained.

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.

Cory Doctorow's DEF CON 31 talk describes how platforms decay in a pattern he calls enshittification. He lays out a plan to stop it through antitrust, interoperability and fixing the law.

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.

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.

Linguist Geoff Lindsey explores vocal fry: what it is, who uses it, how it relates to glottal stops and accents, and why some people dislike it.

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.

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.

A tool-assisted run of Brain Age by TASBot, shown at Awesome Games Done Quick 2016. The bot gives deliberately deranged answers while exploiting the game's error-prone recognition.
