In briefRich Hickey introduces transducers in Clojure, a way to make map, filter and similar algorithms composable independent of the data source. This avoids duplicated implementations and intermediate collections across sequences, channels and streams.
In briefChris Granger, creator of Light Table and the Eve language, gives a Berkeley data science lecture on what computation and programming might look like in ten years. He covers the path that led to Eve and ends with demos.
In briefA five-minute excerpt of Rich Hickey's Clojure Made Simple talk, with new slides, ranting about HttpServletRequest and specificity. He argues for using generic maps instead of many specific classes and getters.
In briefGabriel Lebec's Fullstack Academy talk introduces lambda calculus syntax, the history of mathematical logic, and the essence of functional programming using JavaScript. It also covers combinators, currying and Church encodings.
In briefAaron Bieber, a longtime Vim user, describes his experience trying Emacs with evil mode. He covers what he found, what he missed from Vim, and what Vim could borrow from Emacs.
In briefEvan 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.
In briefEric Bier, a PARC research scientist, demonstrates the Cedar integrated programming environment and language, an evolution of Mesa from Xerox PARC. The demo shows the Tioga editor, garbage collection, and a full graphical workstation environment.
In briefBrandon 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.
In briefJulia co-creator Stefan Karpinski explains why multiple dispatch makes Julia code and types reusable across packages with so little friction. He covers sharing basic types and sharing generic algorithms.
In briefSteve Yegge records himself working in Emacs and shows off about a dozen features in a roughly 45-minute screen capture. It is an informal, enthusiastic tour rather than a structured tutorial.
In briefJoran Dirk Greef's Systems Distributed '23 talk on TigerStyle, the engineering methodology behind TigerBeetle. It covers designing safer systems in less time through up-front design, assertions, and deterministic simulation.
In briefBruce Hauman live-codes Flappy Bird in ClojureScript in about six minutes, using figwheel to hot-reload changes into the running game. The demo shows game behavior being changed interactively without restarting.
In briefJeremy Howard defends Jupyter notebooks as a serious development environment, especially when paired with nbdev. He responds directly to Joel Grus's talk about why he dislikes notebooks, and contrasts REPL-style and notebook-style work.
In briefBrian Fitzpatrick and Ben Collins-Sussman argue that the 'genius programmer' ideal harms collaboration. They advocate trading ego for growth, sharing work early, and understanding how tools shape social behavior.
In briefJohn Kitchin shows how Emacs org-mode with Python lets researchers combine narrative, math, figures and executable code in one document. It exports to LaTeX, HTML and PDF, and he used it for papers and e-books.
In briefDavid Kriesel's 31C3 talk, in German, on the discovery that Xerox scanner-copiers silently replace digits and letters in scanned documents. He explains how the bug stayed unnoticed in the wild for years.
In briefDamian Conway's hour-long keynote at the Perl conference, On the Shoulders of Giants, showing off Perl 6 (Raku) features with history, algorithms and a quantum math operator built with grammars. It is delivered with comic flair.
In briefCal Henderson's DjangoCon 2008 keynote, "Why I Hate Django", is a funny critique of Django from a Flickr architect. It touches on scaling topics such as database replication.
In briefA standing whiteboard conversation at Lang.NEXT 2012 among Carl Hewitt, Erik Meijer and Clemens Szyperski about the actor model. Hewitt, who originated the model, explains its foundations.
In briefLiz Rice live-codes a minimal container runtime in a few lines of Go at GOTO Amsterdam 2018. She explains namespaces, control groups and what a host knows about its containers.
In briefPhoenix creator Chris McCord builds a real-time Twitter-style app live with Phoenix LiveView 1.5 in about 15 minutes. It shows interactive, real-time updates without writing JavaScript.
In briefRichard Feldman explains how pure functional languages can match or beat imperative ones on performance. Compilers can turn immutable code into in-place mutation, avoiding naive copying. The talk draws on his work on the Roc language.
In briefRyan Dahl, the creator of Node.js, introduces the event-driven I/O framework built on V8 with examples, and discusses the v0.4.0 release and its new APIs.
In briefA 2007 Google Tech Talk in which Cliff Click of Azul Systems presents a lock-free concurrent hash table that scales to 768 CPUs. He explains why it is correct by reasoning in a different way than usual happens-before and memory-order arguments.
