如何閱讀code base的組內討論的總結

如何閱讀大型應用程式的code base?我們項目組內部談論了下。有幾點收穫,總結下來:1. 畫UML class diagram (UMLAsSketch)及更高層、抽象層級的圖來協助理解和總結。原則是:Just do what makes things work!不用考慮什麼UML standard的問題。只要畫出的圖有助於自己和別人理解問題,就足夠了。比如順序圖,畫起來很難畫。而且,他面對的代碼層級比較low

如何在低速率網路中測試 Web 應用程式

來自coolshell大家看到標題後的第一個問題可能是:“我們需要這樣做嗎?”如果我們開發的是區域網路 Web 應用程式的話,可能沒有必要這樣做。但如果我們的 Web 應用程式面向的是互連網上的成千上萬的使用者,這樣做就很必要了。因為在現實世界中並不是所有的使用者都有高數率的網路連接,也許使用者使用的是撥號接入,移動設 備,3G,或者是 USB 網路加密狗。如果我們沒有在低數率的網路環境中測試過我們 Web 應用程式,極有可能在上線後收到一些意想不到的關於系統效能方面的抱怨。這個時候無論我們的

[ILDASM Boxing]從進一步瞭解Struct和Class的不同學到的

1. Struct與類的區別:(1)結構是實值型別,不是參考型別。(2)結構可以繼續介面,但是不可以繼承類或結構。(3)結構的構造方法的工作方式有所不同,只能聲明帶參數的構造方法,且不能聲明析構方法。(4)可以指定欄位如何在記憶體中布局。 (5) 使用。如下兩種方法都可以。但是切記:方法一的話,"Users user;" 並沒有調用建構函式初始化成員變數!!所以,總起來講,還是方法二好!以下為MSDN words:The struct type is suitable for

讀書筆記-如何成為技術領導者

1. 三方面的領導力:激勵,組織,創新。每個不同的領導者都是三方面的平衡體。如果你覺得自己“不適合當領導者”,只是你認為的領導者的風格和你自己的不匹配。一般人認為的領導者都有很強的組織、激勵能力。而你,應該是創新型領導者。不要擔心風格問題。2. 建立對自己主體智慧的信心。3. 創新的障礙:第一,無法客觀的看待自己。即使是別人要求你監督他,他們有時也不愛聽你的勸告(時時刻刻處在別人的監督下是很不舒服的);第二,沒問題綜合症(還沒搞清楚問題,就急著下保證說“沒問題”。自己已經知道了所有問題的答案)。
