debugging

An overview of the PTVS 2.0 beta feature for debugging Python and C/C++ together in one session in Visual Studio.

A five-minute demo of the Common Lisp debugger fixing a bug, recompiling a single function, and resuming execution from the failed stack frame. It shows how to avoid re-running long computations.

Allan Blomquist demonstrates the internal programming and debugging tools Tomorrow Corporation uses to make games, including live modification of a running game and time-travel debugging.

A five-minute demo of a live ClojureScript game editor by Chris Granger. It is based on Bret Victor's demo from the Inventing on Principle talk, with code changes reflected instantly in the running game.

Ruby developer Avdi Grimm gives a seven-minute tour of Pharo Smalltalk's development environment, focusing on tools like search-by-example and the integrated, live coding experience.

A five-minute lightning demo of VisiData, a terminal tool for exploring and manipulating data. It uses two months of NYC 311 complaint data to drill down, plot points on a virtual map and save selected rows.

A short overview of Tabs Outliner, a Chrome extension that shows browser tabs and windows as a nestable tree. It demonstrates organizing, saving and restoring tabs.

A seven-minute demo from the author of Notcurses, a C library for text user interfaces. It shows the 2.3.0 release, which adds Sixel and Kitty bitmap graphics integrated into its multiplane character-graphics model.

Saqib Shaikh, a blind developer, shows how he writes and debugs code in Visual Studio 2017 using a screen reader. The short demo shows an expert doing ordinary developer tasks.

A 1991 NeXT promotional video that stages a head-to-head programming contest between a NeXT computer and a Sun workstation. It shows NeXT's interface builder and object-oriented tooling producing an application far faster than traditional UNIX development.

A short demo of Code Bubbles, an IDE interface built around editable code fragments in bubbles instead of files. It was a research prototype for Java development.

A short demo of SEdit, the structure editor for Interlisp-D on Xerox Lisp machines in the 1980s, which edits code as trees rather than text.

The author of lazygit demos 15 features of his terminal UI for git, such as staging individual lines and easier rebasing, aimed at making common git tasks simpler.

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.

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.

Saqib Shaikh, a blind developer at Microsoft, shows at Build 2017 how he writes and debugs code in Visual Studio using a screen reader. This version adds subtitles.

A Gource visualization of 826 days of Minecraft development, from alpha 1.2 to release 1.5, condensed into eight minutes. Each dot is a file, folders are links, and developers fly around zapping files as they work on them.

A demo of Deldo, an Emacs package that lets Emacs hooks trigger vibration events on computer-controllable sex toys. It is an absurd teledildonics project that is half performance art.

carykh demonstrates a script that speeds up the silent parts of a video while leaving speech at normal speed, to condense lectures and similar footage. It later became the Jumpcutter tool.

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.

A short demo of a GPT-powered Linux shell that guesses the bash command you meant and sometimes hallucinates absurd results. The creator stresses that it is real and should not be trusted.

A short Ericsson film demoing Erlang, showing concurrent processes, debugging tools, and hot code reloading, including crashing parts of a running system while calls continue.
