redraiment / Y Combinator 简介

Y Combinator (Fixed-point Combinator) 不动点组合子
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

Backup your OpenShift MySQL database. My DB is only small so I didn't bother to compress it through a pipe. sftp it back from your local machine afterwards This is basically a quick hack from running "type mysql" on the OpenShift gear - hint: it's a bash function/alias
mkdir ~/app-root/data/tmp
mysqldump -h $OPENSHIFT_MYSQL_DB_HOST -P ${OPENSHIFT_MYSQL_DB_PORT:-3306} -u ${OPENSHIFT_MYSQL_DB_USERNAME:-'admin'} --password="$OPENSHIFT_MYSQL_DB_PASSWORD" --all-databases > ~/app-root/data/tmp//all.sql
