今天調整自己的www.it315.org的網域名稱解析工作，看到了CNAME記錄，雖然知道這種記錄表示別名，但是，為什麼要用CNAME，也就是使用CNAME有什麼好處呢？我這種愛思考的人，遇到什麼問題都想知道個究竟，於是google搜尋了一下，真還找到一篇不錯的文章，該文章的標題與本文標題一樣，都是轉抄的，如果大家要知道原創者是誰，可以自己google一下本文的標題，去掉“轉”部分。     

前一陣收到一封網友的來信，信中提到了他在提高個人收入和未來發展中的一些困惑，這也是我們許多學員和網友經常找我諮詢的一件事情，頗具普遍性，故寫此博與大家探討和分享一下。       原信內容如下：-------------------------張老師，你好！我今年23歲，明年12月軟體工程碩士畢業，學Java一直都是深受張老師的感染，是跟著張老師走進IT這個行業，現在又對這行有一定的疑惑，希望老師能夠給予解答！       為什麼JavaEE搞太久之後，會覺得Java搞起來沒意思了，想去搞

構建自己的個人資訊資料庫 金旭亮作為一名軟體開發人員，比較命苦的一點就是——這行的技術更新實在太快了，想保住飯碗並且不被時代所淘汰，就得不斷地學習。另一個讓人鬱悶的是，要開發出一個真正有點用的軟體，用到的知識非常多，象我這種老碼農，記憶力什麼的無法與小年輕相比，經常會出現這種情況： XXX功能我以前實現過，但當年的程式碼我忘記放在哪個地方了，要在N個移動硬碟、幾百G的硬碟上中尋找N年前的代碼，實在無異於大海撈針……我記得在網上看到過某個牛人解決過我現在遇到的這個問題，他還寫了篇文章並有範例程式碼

Unity's rapid edit-compile-test cycle encourages developers to build game levels interactively in the editor. Game parameters are often saved directly in the scene, or on prefabs. However, sometimes it makes sense to read that data from a file at
