最能抓住財富創造方式的人，是很會製造東西的人，常被稱作工匠、師傅。他們的手工藝品成為商店的手工商品，隨著工業化的程度增加，工匠日漸消失，遺留下來的最大族群，叫做電腦程式設計師。

經濟學的角度，"創新"可以視為將人的一生經歷壓縮至短短數年中，與其庸庸碌碌地工作40年，還不如盡全力工作4年。科技產業中，這份衝勁將帶來豐厚的回報，快速工作帶來額外報酬。
--------------------------------------------
要賺到100萬必須忍受100萬價值的痛苦。在郵局工作一輩子，存下的每一分錢最後可以得壹百萬，但必須承受在郵局待 50年所承受壓力。創業家是把50年份的壓力濃縮於數年間體驗，承受與經濟價值相等的痛苦後，通常能取得報酬，這是基本定律。

=======================================================================

* ed1 = 匯率

* ed2 = 台幣

* 計算公式: 美金 = 台幣/匯率 => ed2/ed1

* 學習重點:

* 0) context.findViewById 即 EX203.this (ClassName.this)

* 1) setOn XXX Listener()，建立按鈕事件處理

* 2) new Widget.OnClickListener(){} (口訣:小括號大括號，最末小括號後分號)

* 3) 滑鼠游標移置紅色文字線上 Add unimplemented methods

* 4) 數學換算，與資料型別轉換 in Java

* 5) 覆寫 Activity 的 onPause() 或 onStop()，將匯率儲存下來 (SharePreference物件)

* 6) 覆寫 Activity 的 onResume()，將匯率讀取出來 (SharePreference物件)

ImageJ Tutorial

http://rsb.info.nih.gov/ij/download/examples/

java classpath

java appletviewer

Fiji is easy to install

==================================================================

1.3 Setting up your Environment
For running ImageJ you need the ImageJ class and configuration files, a Java Runtime Environment
(JRE) and—for compiling your own plugins—a Java compiler with the required
libraries, as for example included in the Java 2 SDK Standard Edition (J2SE) from Sun
Microsystems. Depending on the ImageJ distribution you are using, some or all of this may
already be included.
1.3.1 Installing ImageJ
The latest distribution of ImageJ can be downloaded from http://rsb.info.nih.gov/ij/download.
html.
In the following the installation of ImageJ will be described briefly for different operating
systems. More detailed and up-to-date installation instructions can be found at http://rsb/.
info.nih.gov/ij/docs/install.
If you already have a JRE (and a Java compiler) installed on your computer and you are
familiar with Java, you just need to download the ImageJ class and configuration files which
are available as a ZIP archive. To run ImageJ, add ij.jar to your classpath and execute class
ij.ImageJ. This also works for all operating systems for which there is no specific ImageJ
distribution but for which a Java runtime environment is available.
Windows
The Windows version is available with installer, both with and without a Java Runtime
Environment (JRE).
