Not Just Bikes explains the Dutch concept of autoluw, or nearly car-free, streets and how it is applied across the Netherlands, with examples from Toronto and Copenhagen. It also covers Amsterdam's move toward a nearly car-free city.

A VPRO documentary on quantitative analysts who designed the mathematical models and high-speed trading systems behind modern finance. It features figures such as Paul Wilmott and asks what risks come from treating markets as a machine.

A Technology Connections video weighing LED streetlights against high pressure sodium lamps, covering efficiency, color, cost and light pollution. It is a follow-up to his earlier explanation of why street lights are orange.

A Fully Charged episode on Ubitricity, a German company that turns ordinary street lamp posts into roughly 5 kW overnight EV charge points, with a locking cable and managed billing.

Juan Pedro Bolivar Puente explains immutable and persistent data structures in C++ and how they support value semantics. He presents the Immer library, rrb-trees, and a prototype text editor that opens a huge file instantly.

A short Not Just Bikes video on continuous sidewalks in the Netherlands, where the sidewalk runs unbroken across side streets so cars must visibly cross pedestrian space. It places them within Dutch sustainable safety and Vision Zero efforts.

A Microsoft Research talk on BetrFS, a file system built on B-epsilon trees, a write-optimized data structure. It covers WODS such as LSM-trees, how to design a file system around them, and benchmark wins over ext4 and xfs.

Yandex shows its self-driving taxi navigating snowy Moscow streets after a heavy snowfall, dealing with traffic, pedestrians, parked cars and snowbanks on real roads.

A short classic Sesame Street clip in which a mother sends her young daughter to the store to buy a loaf of bread, a container of milk and a stick of butter.

Kent Overstreet's Linux Foundation talk about writing a filesystem in Rust. Its Q&A segment, where Rust-for-Linux developers ask about interface semantics, became widely cited.

A two-minute Google video of its self-driving car handling city street scenarios near the Googleplex. It shows the car dealing with cyclists, pedestrians, construction and a railroad crossing.

Yaron Minsky of Jane Street shows how the OCaml Incremental library lets trading UIs express data transformations that are easy to read and efficient on streaming data. It includes a live table demo.

Not Just Bikes explains why cars rarely crash into buildings in the Netherlands, attributing it to street design that forgives mistakes and to systematic crash investigation. It contrasts this with North American acceptance of such crashes.

Not Just Bikes shows how traffic calming is built into streets across the Netherlands, from city centres to villages. Street design naturally slows cars and makes roads safer.

Kedi is a feature documentary following seven street cats of Istanbul and the people who care for them. It portrays the relationship between the city and its cats.

Not Just Bikes argues that oversized American fire trucks and fire department requirements push cities toward wide roads and dangerous street design. He compares this with the Dutch approach to emergency response.
