remote debugging

Ron Garret tells the story of the Remote Agent Experiment on NASA's Deep Space 1, where autonomous software controlled a spacecraft in 1999. He describes debugging Lisp code remotely from millions of miles away.

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

Stuart Halloway of Cognitect argues for debugging with the scientific method: form hypotheses, try to falsify them, and write everything down. The talk is given to the Clojure community but applies to any language.

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.

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

Bruce Waggoner of the Voyager team describes how engineers diagnosed Voyager 1's 2023 loss of telemetry and patched its flight software from 15 billion miles away. The talk covers the spacecraft's architecture and the scarcity of old documentation.

Bryan Cantrill's 2007 Google Tech Talk on DTrace, showing how dynamic tracing improves debugging of both development and live production systems. It includes a vivid war story about tracking down a problem on a Sun Ray server.

Raymond Hettinger's PyBay 2018 keynote on preventing, finding and fixing bugs under a time budget. He covers testing practice, type annotation tradeoffs and the limits of coverage metrics.

In a long live-coding session, Andreas Kling works on making the Cookie Clicker game playable in the Ladybird browser from SerenityOS. He tracks down bugs in the browser engine and fixes them.

JPL's David Cummings presents at the 2025 Flight Software Workshop how the team diagnosed and fixed the 2023 Voyager 1 anomaly from billions of miles away. It walks through the flight computer and the memory fix.

A 2007 Google Tech Talk in which Bryan Cantrill demonstrates DTrace and explains how it improves debugging of both development and live production systems.

Bryan Cantrill's Uptime 2017 talk on the engineering challenges of the stateful data path, including storage, firmware and hardware bugs. It uses the 'zebras vs. horses' diagnostic heuristic to explain why rare failures keep appearing.

Casey Muratori gives a fast tour of the RemedyBG debugger for Windows, which he uses daily. He shows its speed and features, especially the watch window.

Bret Victor's talk from Dropbox's DBX conference about living by a guiding principle, in his case that creators need an immediate connection to what they are making. He shows live-coding and time-manipulation demos that let ideas take form at the speed of thought.

Netanel Rubin's 31C3 talk chains Perl's syntax quirks into a powerful remote code execution attack, taking down popular Perl-based projects.

Jesse Newland describes how GitHub uses Hubot, its chat bot, to run operations such as deployment, monitoring, graphing and provisioning from chat rooms. He explains how this improves shared awareness and remote work culture.

Aaron Boodman of Replicache asks why sync engines have not yet fixed web app complexity and what is missing for them to go mainstream. The talk lays out the ideas that led to the Zero sync engine.

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.

A 1999 Qwest commercial in which a weary traveler at a remote motel is told every room offers every movie ever made, on demand. It was shot at Roy's Motel in Amboy, California.

Lennart Augustsson's CUFP 2011 keynote covers using Haskell commercially at Standard Chartered Bank. He discusses non-standard Haskell implementations, including a strict dialect, and weighs strict against lazy evaluation.

A 1993 VHS demo of Lucid Energize, a database-backed, incremental C/C++ programming environment built on XEmacs. It shows features like incremental compilation, live debugging and hyperlinked output.
