Getting Memcache and Ruby to Work Together on a Mac with Dali

I've just spent a few minutes banging my head against a wall trying to get Ruby (1.9.2) to work with Memcache, via the Dalli Ruby gem, on my Mac.

Following some pretty simple, clear directions I found via the web, I did this:

brew install memcached

...then

Front-end-Developer-Interview-Questions - 前端工程師面試問題集(繁體中文版)

前端工程師面試問題集

@版本 2.0.0

譯注:此翻譯版,主要給不能流利的讀英文的人看,相關專有名詞還是保留原文。翻譯不好地方請協助pull request.

此repository包含了一些前端開發的面試問題,來審查一個有潛力的面試者。這並不是建議你對同一個面試者問上所有的問 (那會花費好幾小時)。從列表中挑幾個題目,應該就夠幫助你審查面試者是否擁有你需要的技能。

Rebecca MurpheyBaseline For Front-End Developers 也是一篇很棒且值得讀的文章在你開始面試之前。

How to set up your VPS with Chef Solo

How to set up your VPS with Chef Solo

1. What is it?

There are many different provisioning tools out there, the most popular of which are Chef and Puppet. Chef uses Ruby, Puppet uses a DSL (Domain Specific Language), there are others that use simple bash too, but today we're going to focus on Chef Solo.

2. Dependencies

To get Chef working properly on your local machine you need a few things.

Make sure you use Ruby 1.9.x and not Ruby 2.x as you will get errors with the json 1.6.1 gem on 2.x. Use rbenv or RVM to manage several different Rubies on the one machine.

Sample usage of the "android.app.Application.ActivityLifecycleCallbacks" class.
public class MainActivity extends Activity {
private final MyActivityLifecycleCallbacks mCallbacks = new MyActivityLifecycleCallbacks();
@Override
protected void onCreate(Bundle savedInstanceState) {
// Always register before calling into the super class.
getApplication().registerActivityLifecycleCallbacks(mCallbacks);
super.onCreate(savedInstanceState);
