blocking code

A short film about the Erlang language, showing telecom systems built from lightweight processes and demonstrating hot code swapping. It is an edited version of the original Ericsson video.

A short Dyalog demonstration building Conway's Game of Life in a single line of APL, step by step. It shows how array operations replace loops.

A short product demo of Dabble DB, a web tool for importing, entering and manipulating structured data with little effort. It was built in Smalltalk and later acquired by Twitter.

A roughly ten-minute demo of Microsoft's Intentional Programming research system, showing its editor and an unusual way of working with code. It is the first of two clips cut from a longer video.

Steve Jobs demos NeXTSTEP Release 3, showing the object-oriented development environment and UI that later became the basis of Mac OS X. Midway through he builds a database-backed GUI app with Interface Builder and Enterprise Objects Framework with almost no code.

A 256-byte MS-DOS intro that renders a raymarched, procedural 3D animation. It won the 256-byte competition at Riverwash 2009 and the scene.org award for best technical achievement that year, and the author published commented x86 assembly source.

A brief demo of the Smalltalk debugger, including defining a method that doesn't exist yet while the program is stopped mid-crash.

Part 2 of an old Microsoft Research demo of Intentional Programming, showing the compiler side of a system that stores programs as abstract structure rather than text. The uploader says the companion editor clip is clearer.
