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) — ‚Äúlazy man’s chemistry‚ÄĚ: 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.
