A short explainer from Nat and Friends on where Google Earth's 3D imagery comes from, how it is stitched together, and how often it is updated. It describes aircraft carrying camera rigs and photogrammetry that turns the photos into 3D models.

A short animated simulation comparing how Multics and Unix were developed, showing why Unix's small composable programs and pipes gave it a efficiency advantage. It frames Unix as a moonshot achievable by a small team.

Quanta Magazine explains the 2022 experiment that claimed to create a holographic wormhole on Google's quantum computer. The description now notes that a later independent analysis questioned whether any wormhole was created.

Matt Cutts of Google explains what cloaking is: serving different content to search engine crawlers than to users. He covers why it violates Google's webmaster guidelines.

Veritasium argues that Facebook's ad revenue relies partly on fake likes, after paying to promote his page and gaining tens of thousands of followers in developing countries who never engaged. He shares his experiment and cites other cases.

A PBS Infinite Series episode explaining the mathematics of quantum computers, including how qubits store complex numbers and how quantum computation differs from classical computation. Hosted by Kelsey Houston-Edwards.

MinutePhysics explains Shor's algorithm, showing how a quantum computer factors large integers by finding the period of a number modulo N. It walks through the modular arithmetic and number theory that give the exponential speedup over classical factoring, and why this threatens encryption.

PBS Infinite Series explains how Shor's algorithm lets a quantum computer break RSA encryption, building on earlier episodes about cryptography and the math of quantum computers. It works through the idea step by step.

Vox explainer arguing the two Boeing 737 Max crashes were not just a software bug but the result of a company's drive to beat its rival, with a flawed MCAS design.

Corridor Crew tracks down Disney's lost sodium vapor prism process, used for Mary Poppins-era transparency mattes. They explain how a narrow sodium wavelength and a beam splitter enabled better compositing than green screen.

An 8-minute explainer on the Lightning Network and how it relates to Segwit, Bitcoin and Litecoin. It covers how off-chain payment channels route payments to scale blockchain transactions.

IBM's Dr. Talia Gershon explains quantum computing to five people of increasing expertise: a child, teen, college student, grad student and professional. The WIRED series format moves from simple analogies to technical detail.

A short video telling how Xerox PARC invented the graphical user interface and how Steve Jobs's 1979 visit influenced Apple's Lisa.

Technology Connections compares Betamax and VHS picture quality using footage from a 1979 RCA VCR and argues the Beta quality advantage was largely marketing.

Geekerwan reviews smartphone CPUs by power efficiency rather than benchmark scores, with test methodology and chapters on Qualcomm, Apple, Samsung and Google chips. It explains why high benchmark scores can coexist with heat and poor battery life.

Scott Manley examines why SpaceX, Google and others are looking at orbital data centers. He walks through the economics, heat rejection and solar power arguments, with links to the Lumen/Starcloud and Google Suncatcher papers.

Technology Connections explains how touch lamps work and traces them back through patents to the 1950s, far earlier than most people assume.
