An excerpt from Russell Barkley's lecture on ADHD, focusing on inhibition, impulsivity and emotional regulation. It explains ADHD as a problem of response inhibition and emotional impulsivity.

MIT researchers show that sound can be recovered from silent video by analyzing tiny vibrations in objects such as a potato chip bag. It works even with consumer cameras by using rolling shutter.

A very short clip of Carl Sagan saying that to make an apple pie from scratch you must first invent the universe. It illustrates how everything depends on a chain of prior things.

A short National Geographic piece showing a laser system that tracks and kills mosquitoes, filmed in slow motion, as part of anti-malaria efforts. It comes from Intellectual Ventures' 2010 work.

Thunderf00t critiques the MIT and Berkeley metal-organic framework device that claims to pull water from air using only solar heating. He argues the energy accounting does not work and that such devices are essentially fancy dehumidifiers.

Not Just Bikes explains Dutch bicycle-only roads, which let people travel long distances in and out of cities with almost no car interaction. It shows how this changes cycling from a chore into something enjoyable.

Not Just Bikes argues that winter is not what stops Canadians cycling, using Oulu, Finland as proof that safe, well-maintained cycling infrastructure enables year-round biking despite harsh weather.

Andrej Karpathy builds a GPT from scratch in code, following Attention Is All You Need and GPT-2/3, in about two hours using PyTorch. He connects it to ChatGPT and assumes familiarity with his earlier makemore videos.

Lawrence Krauss's 2009 talk on the current picture of the universe, how it will end and how it could have come from nothing. It covers the expanding universe, cosmic background radiation and the cosmological constant.

Chandler Carruth's CppCon 2014 talk on writing fast C++, explaining why data structure choice and memory layout matter more than clever algorithms. It covers why standard containers like unordered_map perform poorly on modern CPUs.

Seattle landscape architect Fred Young gives an hour-long visual tour of Dutch cycling infrastructure, covering design details, continuous networks and how cycling fits daily life in the Netherlands.

Sean Parent's CppCon 2015 talk on better use of standard containers and the goal of having no incidental data structures. It argues that proper containers can greatly simplify code.
