Introduction to React.js - YouTube
- all existing frameworks are based around the "Model -> something"
- the view updates are a pain to maintain and update, it's much easier to blow them away and rerender
- react takes the rerender approach by doing smart diffing between render updates
- the entire DOM representation is maintained in parallel JS structure, which creates overhead but it's not prohibitive and has not been a problem for FB
- JS is fast: comparisons and diffing is fast, doing DOM updates is the bottleneck
- react components call render recursively
- Instagram uses React + Backbone router
- FB ads and likes/comments all based on React
- The final target doesn't have to be DOM: can be canvas, native components, etc.

Guy Winch: The case for emotional hygiene - YouTube
- we are taught about personal hygiene, but not emotional
- often we are our own worst enemies: we deepen the cuts ourselves
- what if, we recognized these patterns and had effective techniques for dealing with them? e.g. shift context to avoid ruminating, etc.
- hygiene significantly improved our longevity; emotional hygiene can do the same for our quality of life

The Connection: Mind Your Body
- all religions use the same mental "trick": shift focus to something outside of self, plus repetition, which allows you to gain distance from that what worries you; meditation is the same concept, but without the religious subtext.
- "gut neurons" - second brain in your stomach?
- feeling of well being does affect your body chemistry, which can have impact on how you feel, etc.

React.js Conf 2015 - YouTube
- react native: layout done on separate thread; UI components are mapped to native components but controlled via JavaScript
- emit full DOM, let the framework handle the diffing via virtual DOM and apply the right transformations
- efficient implementation of immutable structures and tree diffing is the key enabling technology
- virtualizing DOM allows the framework to apply smart transfors (coalesce updates, etc)
- using React: you fall into pit of good performance
- GraphQL: client express the shape of the data they want, the server constructs the response and returns it as described; this removes logic from the server and keeps it on the client - fewer places to update, etc.

Gershon Ben Keren, Krav Maga | Talks At Google - YouTube
- violence is a process: the goal should be to prevent the situations before they develop
- dark alleys and quiet spots are stereotypes, in reality perpetrators want a wide selection, many exit points
- build simple decision trees to react under duress: give them what they want, don't put them under pressure, let them exit and deal with it later
- e.g. burglar in a house: call police, shout "will be here in 5 minutes" to let them exit; chances are they don't want to see you either.

Tim Harford at Mind the Product 2013 on Vimeo
- "chief of marginal improvements" vs. remove yourself from marginal world and go rethink the problem
- "harvard has become a bastion of marginal improvements - e.g. you need to impress those around you?

"Not all innovation is marginal. So often we match the two together. Both areas of innovation are vital. People who bet on long shots don’t have success all the time. They often fail. But we owe it to them to share the risk a little more."
