A Rubber Duck Engineering episode on the years before Flutter, covering web projects and three JavaScript frameworks that influenced it, and the early DOM-based, network-loaded Flutter.

A 37C3 talk on how a series of Polish electric trains stopped working after servicing by an independent company. The speakers explain how train control systems work and how they reverse-engineered the software lockouts.

Internet of Bugs analyzes Cognition's Devin demo frame by frame, arguing the video did not show Devin completing paid Upwork jobs as claimed, and showing what the task required versus what Devin produced.

An engineering explainer on why Tesla abandoned the induction motor for the Model 3 and used an IPM-SynRM design. It covers the reluctance torque and permanent magnet principles behind the choice.

Engineering Explained examines BMW's Hydrogen 7, a V12 that burns liquid hydrogen or gasoline. He covers cryogenic storage at -253C and why the approach is impractical.

Engineering Explained argues that internal combustion engines are far from dead, and discusses the continued development of ICEs and the problems facing electric vehicles.

Rich Hickey's Strange Loop 2011 keynote separates 'simple' (not intertwined) from 'easy' (familiar or near at hand) and argues that software complexity comes from complecting things. It offers a vocabulary for judging designs and abstractions.

Asianometry explains the EUV light source inside ASML's lithography machines, where lasers hit falling tin droplets twice to produce 13.5 nm light. It walks through the engineering of the droplet generator, the pre-pulse and main laser, and the plasma that results.

Linkus7 explains how a community reverse-engineered The Wind Waker to predict its random number generator and beat the Sploosh Kaboom battleship minigame consistently. It includes d3 animations by Peter Schmidt-Nielsen.

Casey Muratori responds on-stream to a dismissive Twitter post by demonstrating how slow Visual Studio's startup and debugger watch window are, comparing it to much older software and machines. It is a long rant about software performance and bloat.
