還在學socket編程嗎?還在研究為什麼epoll比select更好嗎?噢,不必了!在複雜的雲端運算環境中,我們面臨的難題遠比這個複雜得多。龐大的伺服器叢集作為計算雲,對來來看或許只是一個簡單的搜尋方塊;而在雲的內部,複雜的互聯和海量的通訊,加之不穩定的網路環境,廉價伺服器的低可用性——構建一個高可用性且具備伸縮能力的雲端運算的環境,不是那麼容易的!為什麼說ZeroMQ是雲端運算時代最好的通訊庫呢?我們從ZeroMQ的特性來分析吧:1.The socket library that acts
看過network代碼的筒子,會發現類定義的時候,經常出現一個Singleton。為啥要單例啊,這讓我們苦比的中國人情何以堪。Singleton定義如下:template < class type > class SERVER_DECL Singleton{public:/// ConstructorSingleton(){/// If you hit this assert, this singleton already exists -- you can't create

剛開始閱讀英文論文時,首先就碰到了一個問題:搜尋索引鍵是什嗎?我們平時叫“軟體測試”,搜尋"Software Test“往往結果99%不是自己需要的;那麼換個詞”靜態分析 static analysis”呢?結果似乎好了點?再換一下試試“程式分析 program analysis”?還有別的同層級、同意義的關鍵詞嗎?software analysis? program verification? model checking? Abstract Interpretation? Predict
