##MAC OS下安装和配置android-sdk
###安装
在MAC上安装android-sdk,标准的安装方法是使用homebrew
,运行如下命令:
brew update
brew install android-sdk
Options included below:
- Using Docker
docker-compose
- Using Homebrew
brew
This gist was originally created for Homebrew before the rise of Docker, yet it may be best to avoid installing mysql via brew
any longer. Instead consider adding a barebones docker-compose.yml
for each project and run docker-compose up
to start each project's mysql service.
All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
elem.offsetLeft
,elem.offsetTop
,elem.offsetWidth
,elem.offsetHeight
,elem.offsetParent

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important
or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

title: express4.2源码解析 date: 2014-05-18 15:00:50 categories: express tags: [nodejs, node, js, express]
express是nodejs平台上一个非常流行的框架,4.2.0是最新的版本,相比3.x版本优化了代码和api,去除了connect模块,自己实现了一个router组件,实现http请求的顺序流程处理,去除了很多绑定的中间件,使代码更清晰。
##1.使用express 如何使用express在官网有很好的讲解,只用experssjs实例app的几个函数,就可以构建构建web程序。
