Hexagonal Architecture

Conceptualized by Alistair Cockburn. Also known as "Ports and Adapters".

In a nutshell:

Application Driver -> Primary Adapter -> Primary Port -> Use Case -> Secondary Port -> Secondary Adapter -> External System/Side Effect

Golang 面试题 (4) N个协程交替打印1-100
启动N个协程，共用一个外部变量计数器，计数器范围是1到100
开启N个有缓冲chan，chans[i]塞入数据代表协程i可以进行打印了，打印的数字就是计数器的数
协程i一直阻塞，直到chan[i]通道有数据可以拉，才打印

My Vimium Key Bindings (Emacs-Style)

This is a full set of key bindings (as of Vimium v1.45); covering all Vimium functionality. I have tried to map all Vimium functionality to comparable Emacs functionality (whenever possible). In cases where there is no equivalent, those commands are prefixed by <c-g> (indicating <c-g>oogle Chrome; and because <c-g> does not conflict with other Emacs shortcuts at all).

Commented Shortcuts: There are a few Emacs-style shortcuts that are simply not possible in Vimium. All of my shortcuts (including those which were not possible; i.e. where I used a decent alternative) have been commented below. This should help to clarify my rationale.

_Compatibility: All of these shortcuts were tested on Mac OS X (Mavericks). Please note that all of my shortcuts operate under the assumption that your Emacs Meta key is the ⌥ Alt/Option key. This really was my only choice, because the ⌘ key is already used in Chrome for shortcuts that c
