### Decentralised Software, Slow Chemistry, Spectrum Maps, and RF Interference

1. Popcorn Time — interview with the creator. All the elements we used already existed and had done so for a long time. But nobody had put them together in an interface that talked to the user in a nice way, said Abad. Very Anonymous approach to software: Who are you going to sue? The first? The second? The third? I did the design. Was it illegal? I didn’t link the various parts together. There is no comprehensive overview of who did what. For we don’t have any business. We don’t have any headquarters or a general manager.
2. Slow Chemistry (Nature) — “lazy man’s chemistry”: let a mix of solid reactants sit around undisturbed while they spontaneously transform themselves. More properly called slow chemistry, or even just ageing, the approach requires few, if any, hazardous solvents and uses minimal energy. If planned properly, it also consumes all the reagents in the mix, so that there is no waste and no need for chemical-intensive purification.
3. Mapping the Spectrum in the Mission — SDR scanner to make a map of spectrum activity.
4. Electronic Noise is Drowning Out the Internet of Things (IEEE Spectrum) — (paraphrasing) increases deployment costs, decreases battery life, creates interference, ruins policies of spectrum allocation, is expensive to trace, and almost impossible stop.

### Nanoscale Motors, Language of Betrayal, Messaging, and Handing Off Culture

1. Nanoscale Motors (Nature) — “We’ve made 50 or 60 different motors,” says Ben Feringa, a chemist at the University of Groningen in the Netherlands. “I’m less interested in making another motor than actually using it.” An interesting summary of the progress made in nanoscale engineering.
2. Linguistics Signs of Betrayal — as found by studying Diplomacy players. Betrayers suddenly become more positive, possibly attempting to hide their duplicity. Betrayers suddenly become less polite, after having kept up a façade of politeness, during which the victims were significantly less polite. A reversal of imbalance occurs right before the betrayal. Victims plan more. Making a lot of plans can put pressure on the relationship and hasten betrayal, and, at the same time, if the betrayer’s mind is made up, there is no point for him to plan.
3. NATS — open source (MIT-licensed) messaging system that shares the best name in the world.
4. Building a Culture and Handing it Off (Kellan Elliott-McCrea) — Successfully building a culture ensures when you leave you can hand your work off to people you trust and they will run the thing without you and make it better than you could have imagined.

### Auto-Remediation, Fast and Good, Life's Game of Conway, and Self-Assembly Lab

2. Moving Fast With High Code Quality (Quora) — Lots of practical detail about how they combine speed with quality.
3. John Horton Conway (The Guardian) — These were two separate areas of study that Conway had arrived at by two different paths. So, there’s no reason for them to be linked. But somehow, through the force of his personality, and the intensity of his passion, he bent the mathematical universe to his will. Fascinating profile, taken from a new book.
4. MIT Self-Assembly Labmulti-material 3D/4D printing, advances in materials science, and new capabilities in simulation/optimization software […] made it possible to fully program a wide range of materials to change shape, appearance, or other property, on demand.

### Self-Assembling Chairs, Home Monitoring, Unicorn Horn, and Cloud Security

1. MIT Scientists and the Self-Assembling Chair (Wired) — using turbulence to randomise interactions, and pieces that connect when the random motions align. From the Self-Assembly Lab at MIT.
2. Calaosa free software project (GPLv3) that lets you control and monitor your home.

### Discourse 1.0, Programmable Matter, Versioned Databases, and What Humans Learned About Machine Learning

1. Discourse turns 1.0 — community/forum software that doesn’t suck.
2. Programmable Matter (IEEE Spectrum) — recap of where research is going in this area.
