在一个数据结构上运行100个函数比在10个数据结构上运行10个函数要好。
It is better to have 100 functions operate on one data structure than 10 functions on 10 data structures.
Humility is the first lesson farming teaches us.
We search through historical data looking for anomalous patterns that we would not expect to occur at random. Our scheme is to analyze data and markets to test for statistical significance and consistency over time. Once we find one， we test it for statistical significance and consistency over time. After we determine its validity， weask， ‘Does this correspond to some aspect of behavior that seems reasonable？’
