John Resig - JavaScript as a Language - 2 views

*精華* javascript programming

shared by Benx Shen on 12 Jul 07 - Cached
  • I think we"ve seen the JavaScript language move through many individual phases: The "We need scripting for web pages" phase. (Netscape) The "We should standardize this" phase. (ECMAScript) The "JavaScript isn"t a toy" phase. (Ajax) The "JavaScript as a programming language" phase.

      John Resig 認為，Javascript 歷經了這些成長階段： 1. "網頁所需的腳本(script)語言" (網景 Netscape) 2. "標準化" (ECMAScript) 3. "不只是玩具" (Ajax) 4. "成為真正的程式語言" (!?)

  • JavaFX Script™ （下文中成為JavaFX）語言是一種聲明式的靜態類型編程語言。它具有第一級函數（first-class functions）、聲明式的語法、列表推導（list-comprehensions）及基於依賴關係的增量式求值（incremental dependency-based evaluation）等特徵。JavaFX 腳本式語言特別適用於Java2D swing GUI組件，它允許簡單地創建圖形界面。 譯者註：第一級函數指函數被當作對象對待，可以在運行時賦值、傳遞和返回。詳見wikipedia上的解釋。 譯者註：列表推導指一種在函數語言中的表達式，它表示了在一個或者多個列表的成員（被選擇的）進行某種操作的結果。它被稱為"syntactic sugar"，即為開發者提供了便捷的多種函數的應用組合。詳見FOLDC對list comprehension的解釋。 本文檔給出了JavaFX 腳本式編程語言的非正式描述。

      這裡是一個範例，可以看到透過 DOMCategory 的協助，xml dom 元素的存取直接可以用 "expression" 的方式就可以很方便地取用，而不需要很囉唆地 getElement() 或之類的

Preventing Java's java.lang.OutOfMemoryError: PermGen space failure | Eric's Agile Answers - 0 views

*i_comment* exception java memory permgen_space runtime

shared by Benx Shen on 22 May 07 - Cached
  • The "OutOfMemoryError: PermGen space" message is normally encountered during development activites where a long-running JVM is asked to load/unload builds.
  • The message is a symptom of an incomplete garbage collection sweep where resources are not properly released upon unload/restart. There is no shortage of debate (Hibernate forum, Sun forum, Spring Framework forum ) regarding which codebase is responsible for this symptom, but the finger of blame has been pointed at CGLIB, Hibernate, Tomcat, and even Sun's JVM.
  • In my experience, the most pain-free method of resolving this issue is to switch from Sun's JDK implementation to BEA's freely available JRockit implementation.
  • ...1 more annotation...
  • On a recent project utilizing Tomcat 5.5.12 with Hibernate, I was plagued with this PermGen error, at times even experiencing it during web-based unit testing. Since making the switch to JRockit, I have not encountered this issue even once.

    又是一位和我一樣都慘遭 "PermGen Space" 錯誤的開發者了！
    很奇怪，為何會發生這樣的錯誤呢？
    其中這篇文章所提到的技術，恰巧都是我現在所發生問題的架構，像是 Hibernate, Spring, Tomcat 等，還有 Sun JVM.... Orz
    比較特別的是，多數提供的解決方式，都是去調整 JVM 的設定（-XX:MaxPermSize=256m）。這位老兄則是採用了 BEA JRockit 版本的 JVM 解決此問題，他表示至少這招對他是管用的！
    不過，軟體開發很多時候都會發生這種「魔咒」，這種狀況底下，就好像一個並無可醫的人，只好嘗試各種偏方了！

synchronized thread threadlocal 討論

    對於 java synchronized 的機制多所討論，並且發文者 klyuan 提出了不少測試代碼嘗試讓讀者更能夠跟著學習測試，我覺得真的很棒。雖然，他對於 synchronized 和 threadlocal 的見解的確是有些小錯誤，threadlocal 確實不是在解決多執行緒中資源共享的問題，但我想 klyuan 其實是想使用 threadlocal 來解決「多執行緒中非共享資源的保護」問題。

jvm memory permgen_space

shared by Benx Shen on 22 May 07 - Cached
  • 發現很多人把問題歸因於： spring,hibernate,tomcat，因為他們動態產生類,導致JVM中的permanent heap溢出 。然後解決方法眾說紛紜，有人說升級 tomcat版本到最新甚至乾脆不用tomcat。還有人懷疑spring的問題，在spring論壇上討論很激烈，因為spring在AOP時使用CBLIB會動態產生很多類。
  • 於是有人對更基礎的JVM做了檢查，發現了問題的關鍵。原來SUN 的JVM把內存分了不同的區，其中一個就是permenter區用來存放用得非常多的類和類描述。
  • 對這個bug最徹底的解決辦法就是不要用SUN的JDK，而改用BEA的 JRokit.
