Psychohistory depends on the idea that, while one cannot foresee the actions of a particular individual, the laws of statistics as applied to large groups of people could predict the general flow of future events. Asimov used the analogy of a gas: an observer has great difficulty in predicting the motion of a single molecule in a gas, but can predict the mass action of the gas to a high level of accuracy. (Physicists know this as the Kinetic theory). Asimov applied this concept to the population of his fictional Galactic Empire, which numbered a quintillion. The character responsible for the science's creation, Hari Seldon, established two axioms:
that the population whose behaviour was modeled should be sufficiently large
that the population should remain in ignorance of the results of the application of psychohistorical analyses
There is a third underlying axiom of Psychohistory, which is trivial and thus not stated by Seldon in his Plan:
that Human Beings are the only sentient intelligence in the Galaxy.
Rake is Ruby Make, a standalone Ruby utility that replaces the Unix utility ‘make’, and uses a ‘Rakefile’ and .rake files to build up a list of tasks. In Rails, Rake is used for common administration tasks
“I’ve been beating my head against a wall for the last two years trying to make a news app experience work,” he wrote. “And despite great reviews, I’ve failed.” Only the mobile apps will be discontinued — the news service itself will live on.
Why has Bitcoin failed? It has failed because the community has failed. What was meant to be a new, decentralised form of money that lacked “systemically important institutions” and “too big to fail” has become something even worse: a system completely controlled by just a handful of people. Worse still, the network is on the brink of technical collapse. The mechanisms that should have prevented this outcome have broken down, and as a result there’s no longer much reason to think Bitcoin can actually be better than the existing financial system.
Whether this should be the law—whether, in the absence of a judicial finding of guilt, the state should be able to take possession of your property—has been debated since before American independence. In the Colonial period, the English Crown issued “writs of assistance” that permitted customs officials to enter homes or vessels and seize whatever they deemed contraband. As the legal scholars Eric Blumenson and Eva Nilsen have noted, these writs were “among the key grievances that triggered the American Revolution.” The new nation’s Bill of Rights would expressly forbid “unreasonable searches and seizures” and promise that no one would be deprived of “life, liberty, or property, without due process.”
