Asides

On what can be developed on Ethereum

  • A globally accessible financial system, including payments, store of value, also more advanced stuff like insurance http://hurricaneguard.io/
  • Identity: “sign in with Facebook” -> “sign in with an ethereum account, no intermediaries”. Also web of trust
  • All sorts of registries should publish on chain for security and easy verifiability, see my thread on this https://twitter.com/vitalikbuterin/status/1072158957999771648
  • Experimenting with new forms of human organizational structure, eg. @MolochDAO
  • All sorts of micropayment use cases via payment channels
  • Markets for personal data for privacy preserving machine learning (you pay me X, I let you homomorphically execute function Y on my data that’s been attestated to by Z…)
  • Cryptoeconomics for spam prevention in social networks
  • Cryptoeconomics / micropayment schemes to reward publishers of good content
  • Testing ground for new market designs, eg. frequent batch auctions, combinatorial auctions, automated market makers (eg. http://uniswap.exchange )
  • Stickers/badges
  • p2p marketplace for internet connections / incentivized mesh networks
  • Identity, reputation and credit systems for those that currently have few resources (eg. refugees)
  • Decentralized DNS alternatives (eg. http://ens.domains/ )

On ways of complaining

Shenma said it tried contacting Tesla multiple times but the carmaker has “low efficiency in internal communications” and the complaints “take too long,” according to the Weibo post.

.

The firm said its billboard stunt was inspired by the film Three Billboards Outside Ebbing, Missouri, and New York was chosen because that is where Tesla’s shares are listed.

.

The electronic messages on the billboards were in Chinese: “Tesla, fix it or not,” “Tesla, compensate or not,” and “Tesla, admit it or not.” Printed under those slogans were Shenma’s loss in numbers—including the 20% fault rate and 3.5 million minutes of driving time lost due to cars took out of service for repairs.

On energy efficiency of various languages



Energy usage is *very* complicated – If you want low energy use VLSI or an FPGA and NOT a programming language – true total lifecycle energy costs are very very difficult to calculate – more of a physics/hardware question than a programming problem.
