Web Spreadsheet, Correlated Novelty, A/B Ethics, and Replicated Data Structures

  1. EtherCalcopen source web-based spreadsheet.
  2. Dynamics of Correlated Novelties (Nature) — paper on “the adjacent possible”. Here we propose a simple mathematical model that mimics the process of exploring a physical, biological, or conceptual space that enlarges whenever a novelty occurs. The model, a generalization of Polya’s urn, predicts statistical laws for the rate at which novelties happen (Heaps’ law) and for the probability distribution on the space explored (Zipf’s law), as well as signatures of the process by which one novelty sets the stage for another. (via Steven Strogatz)
  3. On The Media Interview with OKCupid CEO — relevant to the debate on ethics of A/B tests. I preferred this to Tim Carmody’s rant.
  4. CRDTs as Alternative to APIswhen using CRDTs to tie your system together, you don’t need to resort to using impoverished representations that simply never come anywhere near the representational power of the data structures you use in your programs at runtime. See also this paper on Convergent and Commutative Replicated Data Types.

Decentralised Consensus, Disruption Critiqued, Digital Reputation, and Stuff That Matters

  1. Erisa platform which allows developers and users to deploy consensus driven applications which rely on decentralized architecture and a consensus driven blockchain database backend. Open source (modified MIT).
  2. The Disruption Machine (New Yorker) — long detailed critique of the “disruption” hypothesis of Clayton Christensen, particularly questioning the case studies cited in The Innovator’s Dilemma.
  3. Web Reputation Systems and the Real World (Randy Farmer) — Don’t cross the streams. Good digital reputations should always be context-limited: the nature of the inputs should constrain the use of the reputation scores that are output.
  4. Bill and Melinda Gates Commencement Speech (Quartz) — excellent urging to work on stuff that matters. The pessimists are wrong in my view, but they’re not crazy. If innovation is purely market- driven and we don’t focus it on the big inequities, then we could have amazing advances and inventions that leave the world even more divided.
