optical fiber

A two-hour NANOG tutorial by Richard Steenbergen aimed at network engineers, covering optical networking technologies. This is the updated 2017 edition of a recurring talk.

Lin Clark gives an illustrated, cartoon-style walkthrough of React Fiber, the rewrite of React's reconciler, explaining its incremental rendering and scheduling at React Conf 2017.

Jared Mauch tells how he got fed up with poor internet options in rural Michigan and built his own fiber network to his town. The talk was given at NLNOG Live in September 2020.

Huygens Optics explains the Fourier transform and shows how a lens performs one optically. A DLP projector is used as a Fourier filter to do simple pattern recognition on lithographic character patterns.

A Corning-sponsored video in which Adam Savage and Jamie Hyneman introduce flexible, bendable glass. It covers the history of glass innovation with demonstrations of bendable optical fiber and ultra-thin glass.

Neuroscientist Beau Lotto runs the audience through color and pattern illusions to show that perception is shaped by context and evolutionary history rather than being a direct readout of the world. The talk is playful and hands-on, and it argues that the brain interprets ambiguous signals.

Real Engineering explains why SpaceX is building Starlink, including the economics of satellite internet. It covers the latency advantage of light in vacuum over fiber for long-distance links.

Paul Turner of Google presents kernel interfaces for user-level scheduling of real threads, aiming at a uniform synchronous programming model across C++, Java, Go and Python. It introduces the switchto-style system calls behind Google's fibers.

An Autoline After Hours episode where Sandy Munro discusses his complete teardown of the BMW i3, along with automotive journalists. It covers the car's carbon fiber construction and manufacturing technology.

Footage shot with a Nikon P1000 superzoom camera showing extreme optical zoom on distant targets from Ben Lomond in Scotland.

Tom Scott visits IEX, a stock exchange that slows down trading with a long coil of fiber. The coil removes the speed advantage of high-frequency traders.

A short tour of a UK materials recycling facility showing how mixed recyclables are mechanically and optically sorted. Aluminum, ferrous metal, glass, paper, and trash come out as separate streams.

Danny MacAskill tries to destroy carbon fiber bike wheels by riding trials tricks through downtown Glasgow, including on bare rims on concrete.

Toyota's short promo clip showing a Mirai carbon-fiber hydrogen tank shot with a .50 caliber round at point blank range. The bullet pierces the tank, which does not burst, and the gas simply escapes and disperses.

Inventor Mary Lou Jepsen demonstrates using red light and sound to see inside the body and brain, aiming at tumor detection and neural activity measurement, and potentially a cheaper wearable MRI replacement.

Robert Lustig of UCSF lectures on the biochemistry of sugar, arguing that fructose and lack of fiber drive the obesity epidemic via insulin. It is the widely viewed 90-minute talk that popularized the anti-sugar case.

A motorcycle safety video on the SMIDSY (sorry mate, I didn't see you) accident, explaining the perception and optical illusion that makes drivers fail to see riders, and how riders can spot the signs and avoid it.

Mark Handley of UCL looks at how SpaceX's November 2018 revisions to the Starlink constellation affect network behavior. The video visualizes the orbits and routing and estimates latencies, building on his earlier video and research paper.

A look inside Dr Abrasive's lab as he engineers a flash-card replacement for the Sega Saturn optical drive after cracking its CD protection 20 years on.

A short visualization from HotNets researchers of routing and latency over SpaceX's proposed Starlink constellation, based on its FCC filings. It shows orbital shells, link topology and how inter-satellite routes could beat terrestrial fiber on long distances.

A long Huberman Lab podcast episode with Dr. Robert Lustig on the calories-in, calories-out model and how sugar, fructose, fiber and processed foods affect insulin, liver and metabolic health.

A 41-minute factory tour showing how the BMW i3 electric car is built from start to finish, in the style of a Megafactories documentary. It shows a highly automated production line with carbon-fiber body construction and robots doing most of the work.

Ben Krasnow of Applied Science builds a DIY microbalance from an analog panel meter with an optical servo loop. It reaches about 5 micrograms of precision and is used to weigh a single eyelash at around 35 micrograms.

A video showing a virtual camera built in Blender that simulates lenses and film layers using path tracing, to make physically modeled photographs.

A Swedish fiber provider's short experiment in which volunteers wear Oculus Rift headsets that add lag to their view of real life. They try to do everyday tasks like making pancakes.

A one-minute clip showing an injury from a DJI Phantom 2 drone with stiff carbon fiber propellers. It is a warning about hobby drone safety.
