Glenn Vanderburg argues at the O'Reilly Software Architecture Conference that software development is an engineering discipline, even if immature. He contends the discredited body of knowledge called software engineering has led people to wrongly reject the label.

A Linear engineer talks about scaling the company's sync engine, which keeps client data local and synchronized. It follows an earlier talk on the same system.

Scott Manley explains rotating detonation engines, how they differ from pulsed detonation engines, and why thermodynamics predicts they beat traditional jet and rocket engines.

Hillel Wayne reports on interviews with 17 people who have worked as both software and traditional engineers. He argues the fields are fundamentally the same and have much to learn from each other.

Episode 7 of the Inside Koenigsegg series, where Christian von Koenigsegg demonstrates the camless Free Valve engine technology. It discusses how such innovation could affect the wider auto industry.

A Tom Scott guest video by Grady Hillhouse of Practical Engineering on the 1981 Hyatt Regency walkway collapse. A seemingly minor change to the support design led to catastrophic failure, which is why the case is taught as a lesson to check and double-check everything.

A short test firing of the XRS-2200 linear aerospike engine at NASA Stennis Space Center, which was designed for the cancelled X-33 VentureStar. The engine is shown at roughly 80 percent of max thrust.

Miguel de Icaza's GodotCon 2023 talk on Swift bindings for Godot. He argues that garbage-collector pauses in C# are a persistent problem and that Swift's reference counting avoids them.
