农历年应该从什么时候开始计算

今年是龙年，大家都想生一个龙baby，但是我们中国的农历年应该从什么时候开始计算了

1.现在的农历年是每年的农历一月初一，是从民国时开始的；

2.真正的农历年开始应该从春分开始计算。2012年也就是阳历2月4号。

IC测试的基本理论

IC 测试基本原理：drive inputs to the DUT(device under test), and measures signals
from the DUT
给一个输入，根据DUT的逻辑来测量输出
Digital: drive low/high, measure low/high
输入高低电平或电流，测量高低电平或电流；
Analog: drive sine singal, measure signal-to-noise ratio(SNR) ;
输入sin波，测量信噪比；
这里需要感谢傅立叶：
任何一个波形都可以分解成无限多个sine波的叠加；
时域和频域可以相互转换
RF: ?
Memory: ?

the command-line window of vim

command-line window of vim就是把vim在:模式下输入的命令列出来的窗口，当你保存文件时，按错键，会进入该窗口；

下面两种方法会进入该窗口：
There are two ways to open the command-line window:
1. From Command-line mode, use the key specified with the ‘cedit’ option.
The default is CTRL-F when ‘compatible’ is not set.
2. From Normal mode, use the “q:”, “q/“ or “q?” command.
This starts editing an Ex command-line (“q:”) or search string (“q/“ or
“q?”). Note that this is not possible while recording is in progress (the
“q” stops recording then).
如何退出：
把它当成正常的文件输入:q，就可以退出了。

Application.DisplayAlerts = True
End Sub

7. get table range
Sub GetTableRange(ByRef lastTableIndex As Integer)
Last = ActiveSheet.Underline(Rows.count, “A”).End(xlUp).Row
Dim myInterior As Interior

Eclipse

SWT的PaintListener

给swt中的control追加Paintlistener，listener被调用的先后顺序和Control 被布局(不包括父子关系)的先后顺序有关
；
每个Control 都在org.eclipse.swt.widgets.Display类中的变量：Control [] controlTable;
按照被布局的先后顺序被组织起来；
在调用PaintListener时，Control已经有size了；
因为parent和child的PaintListener被调用的先后顺序不一样，所以
不要在父亲里面去取孩子的相关信息，每个Control取得自己的信息和进行Paint就好
