Y组合子是Lambda演算的一部分,也是函数式编程的理论基础。 | |
它是一种方法/技巧,在没有赋值语句的前提下定义递归的匿名函数。 | |
即仅仅通过Lambda表达式这个最基本的“原子”实现循环/迭代。 | |
颇有道生一、一生二、二生三、三生万物的感觉。 | |
虽然Y组合子在理论上很优美,但在实际开发中并不会真的用到。 | |
想要了解Y组合子是什么,请参见维基百科:http://en.wikipedia.org/wiki/Fixed-point_combinator#Y_combinator | |

// This started as a tweet with a joke of "C++ pro-tip: #define private public", | |
// and then it quickly escalated into more and more evil suggestions. | |
// I've tried to capture interesting suggestions here. | |

To install scikit-learn easily run the following command.
curl https://gist.githubusercontent.com/dacamo76/4780765/raw/c3779996d8f6b13caaaa48d33aa1585684c7f8e6/scikit-learn-install.sh | sh
Please look over the shell file being run to make sure no evil is done to your machine.
the new github notifications (https://github.com/blog/1204-notifications-stars) leaves me wanting more!
notifications settings should let you choose whether or not to receive emails for the above things. there should also be a web UI that shows you a list of all comments/messages for the above scenarios. at the moment https://github.com/notifications only shows you github issue names which is less useful than showing the actual message (the old notifications page showed actual messages)
