XML Format in Console
xmllint is a command line xml tool in console to parse one or more xml files. It also can print type of output by the options selected and detect erros both in XML code.
But I mainly used it to format XML format, by using aliases, it can save a lot of time when doing XML format task.
alias xmlformat="xmllint --c14n '$*' | XMLLINT_INDENT=$' ' xmllint --encode UTF-8 --format -"http://xmlsoft.org/xmllint.html
What is Refactoring?
A series of small steps, each of which changes the program's internal structure without changing its external behavior - Martin Fowler

Rod Johnson: Things I Wish I’d Known
InfoQ: Things I Wish I'd Known
看完Springframework創始人Rod Johnson創業過程，有些想法真非常適合工程師要如何創業。
也對他的背景非常感到興趣；音樂博士 + 電腦專才所發展出來的Springframework或許滿值得研究!
個人是比較欣賞務實工作理念

沉默ClassLoader
JVM環境中沉默英雄ClassLoader，無聲無息將Java Class載入至JVM讓程式能夠於JVM運行。
瞭解ClassLoader定義
The Java Classloader is a part of the Java Runtime Environment that dynamically loads Java classes into the Java Virtual Machine.[1] Usually classes are only loaded on demand. The Java run time system does not need to know about files and file systems because of class loaders. Delegation is an important concept to understand when learning about class loaders.
為什麼需要瞭解它
雖然在大部份時間我們並不需要去瞭解它，甚至不會感覺它的存在，但總是有一些特別的需求需要自行客制化ClassLoader。
- 單純想瞭解它的運作
- 程式可能存在網路某個地方與不同存取協定
- 能夠在運作時重新載入程式(jar, class) JRebel
- 安全性考量用來載入特殊格式(加密格式)
- 御載(unload)程式在某些極端因素考量下
- 客制化
