Stephan T. Lavavej's GoingNative 2013 talk explaining why calling rand() and using rand() % 100 is bad in C++, and how the C++11 <random> header does the job properly.

Richard Wilkinson presents data showing that societies with larger income gaps do worse on health, lifespan, trust and other measures. He argues the effects track inequality itself rather than average income. It is a 17-minute TED talk.

Soil microbiologist Elaine Ingham speaks at the Oxford Real Farming Conference on how soil organisms cycle nutrients, unlock minerals from rock and air, and why pesticides and fertilizers harm soil life. Slides are linked in the description.

Marcin Jakubowski of Open Source Ecology presents his plan to open-source blueprints for 50 cheap, buildable farming tools, a "civilization starter kit". He argues that opening the means of production can enable self-sustaining lives.
