gestural interface

Erik Meijer argues that category theory is the mathematicians' version of interface-based design. He shows that Java 8 lambdas and method references form a Cartesian closed category.

Pranav Mistry demos SixthSense, a wearable device that projects information onto the physical world and lets people interact with data through gestures. He also shows a paper "laptop" and says he will open-source the software.

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.

A Google Tech Talk arguing that the best interface requires the fewest clicks and choices, with Google search, Facebook, the iPod and Firefox as examples. It shows how minimizing interaction makes interfaces easier to learn.

Bret Victor's closing keynote at UIST and SPLASH 2014 argues that our tools for thinking ignore most of human sensory and motor capability. He sketches representations that engage more modalities beyond screens and keyboards.

Andrew Price presents at the Blender conference on the problems, politics and possible fixes for Blender's user interface, followed by a full Q&A. He argues that an interface upgrade is overdue.

Jason Perkins's talk at Vintage Computer Festival East 2020 compares the user interface of the Xerox Star with that of the Apple Lisa. It covers editing documents, the Star's mouse and a Q&A.

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.

Rich Hickey's 2013 talk applies language-design thinking to whole systems, covering names, queues, data, failure, and the interfaces between programs. It ends with a call to action for building systems holistically.

A full upload of Alan Kay's 1987 talk, with demos of several Smalltalk-era software systems and ideas about visual, kinesthetic and symbolic reasoning. It includes a Smalltalk program written by a 12-year-old and footage of the Rand tablet.

David MacKay's 2007 Google Tech Talk presents Dasher, a text-entry system driven by continuous gestures and a language model, reaching about 35 words per minute with one finger and 25 hands-free. It explains the information-theory reasoning behind the design.

Bret Victor's talk on Drawing Dynamic Visualizations. It argues that visualization tools offer either the directness of hand drawing or the dynamics of programmed graphics, and shows a tool that combines both.

A short talk by Will Dayble of Squareweave arguing that you should design software as if the user were drunk: distracted, impaired in attention and vision, and prone to misreading. It is a user experience talk built around that framing.

A MIX08 session from Microsoft's Office team on how the Office 2007 ribbon was designed. It explains the user-feedback and telemetry behind it and the alternatives that were rejected.

Scott Jenson, a veteran UX designer formerly at Apple and Google, argues that the 'UX/UI' split pits programmers against designers and narrows ambition in open source. He makes the case that desktop UX has stagnated and that open source projects could lead experimentation beyond current interaction models.

Ian Cooper's DevTernity talk revisits Kent Beck's original TDD ideas and shows where misunderstandings crept in. It argues tests should target behaviors through public interfaces rather than implementation details, so suites support refactoring instead of resisting it.

John Ousterhout, Stanford professor and creator of Tcl, presents the ideas of his book A Philosophy of Software Design in a Talks at Google session. He covers managing complexity, deep modules and interfaces, and what he teaches in his Stanford software design course.

A short !!Con 2016 talk by blind developer Sina Bahram on how he uses a computer and writes code with a screen reader at about 1,000 words per minute. He plays how common interfaces sound and challenges the audience to go a day using only the keyboard.

Paul Turner of Google presents kernel interfaces for user-level scheduling of real threads, aiming at a uniform synchronous programming model across C++, Java, Go and Python. It introduces the switchto-style system calls behind Google's fibers.

Greg Law's 15-minute CppCon 2015 lightning talk shows what GDB can do beyond basic use, including its text user interface and reverse debugging.

Sandi Metz's RailsConf 2013 talk offers practical guidelines for deciding what to test and how, so tests stay cheap and stable. She argues for testing the public interface rather than implementation and using mocks appropriately.

James Mickens's 2015 Harvard colloquium argues that browsers are bloated and insecure because feature races trump clean interface design. He presents a cleaner, more secure browser architecture (Atlantis) with a much smaller API surface.

Bret Victor's 2013 MIT Media Lab talk argues that the media we think with determine which thoughts are possible. He demos new representations for scientific papers, circuits, filters and signal processing.

Alan Kay argues for rethinking how computer science is taught in schools, drawing on his work on object-oriented programming and GUIs. He discusses how poorly people understand complex systems and what education could do about it.

The full January 2007 Macworld keynote where Steve Jobs unveils the first iPhone. It covers the touch interface, multitouch gestures, the browser, maps and the pitch as an iPod, phone and internet communicator.

A clip in which Eben Moglen tells how he grew up when software was freer and how his path crossed Richard Stallman's. He describes how they came to work together to make software free again.

An edited excerpt of Steve Jobs introducing Mac OS X at Macworld San Francisco in 2000. It covers the Aqua interface, Quartz graphics built on PDF, and the Classic, Carbon and Cocoa application environments.

Jensen Harris of the Office 2007 design team tells the behind-the-scenes story of the Ribbon at MIX08. He covers early prototypes, mistakes, and the UX principles used to design and validate it.

Allan Jude of Klara presents work on making ZFS scale on fast NVMe storage, covering fixes to the TaskQueue interface and removal of bottlenecks. The talk was given at EuroBSDcon 2022 and describes raising write throughput from about 3 to over 7 GB/sec.

Walter Bright explains to the Northwest C++ Users Group how the D programming language can interface directly with legacy C++ code. He covers why C++ is hard to interface with and how D approaches the problem.

Kent Overstreet's Linux Foundation talk about writing a filesystem in Rust. Its Q&A segment, where Rust-for-Linux developers ask about interface semantics, became widely cited.
