最近使用阿里云写一些python服务，pip安装的时候经常出现下面情况：
Downloading/unpacking uwsgi
Cannot fetch index base URL https://pypi.python.org/simple/
Could not find any downloads that satisfy the requirement uwsgi
Cleaning up...
No distributions at all found for uwsgi
Storing debug log for failure in /home/sickworm/.pip/pip.log
解决办法是：
连续执行两次，第一次失败，第二次成功。或你可以试试删除个人目录下的.pip文件夹。

内容为Mou软件示例，Mou是一款Mac的MarkDown软件，支持即时预览，Mou预览版免费。JetPack不支持即时预览，建议使用Mou编辑完成后再上传到WordPress。（注意Web版应在“文本”中编辑，而不是在“可视化”中编辑，否则会有格式转换的问题，如代码缩进）
MarkDown和Crayon协同工作参考此处。
Mou, the missing Markdown editor for web developers.
strong or strong ( Cmd + B )
emphasize or emphasize ( Cmd + I )
Sometimes I want a lot of text to be bold.
Like, seriously, a LOT of text
Right angle brackets > are used for block quotes.
An email example@example.com link.
Simple inline link http://chenluois.com, another inline link Smaller, one more inline link with title Resize.
A reference style link. Input id, then anywhere in the doc, define the link with corresponding id:
Titles ( or called tool tips ) in the links are optional.
An inline image , title is optional.
A reference style image.
Inline code are surround by backtick key. To create a block code:
Indent each line by at least 1 tab, or 4 spaces.
var Mou = exactlyTheAppIwant;
Ordered lists are created using “1.” + Space:
Unordered list are created using “*” + Space:
Or using “-” + Space:
End a line with two or more spaces will create a hard linebreak, called <br /> in HTML. ( Control + Return )
Above line ended with 2 spaces.
Three or more asterisks or dashes:
Setext-style:
atx-style:
Footnotes work mostly like reference-style links. A footnote is made of two things: a marker in the text that will become a superscript number; a footnote definition that will be placed in a list of footnotes at the end of the document. A footnote looks like this:
That’s some text with a footnote.1
Wrap with 2 tilde characters:
~~Strikethrough~~
Start with a line containing 3 or more backticks, and ends with the first line with the same number of backticks:
Fenced code blocks are like Stardard Markdown’s regular code
blocks, except that they’re not indented and instead rely on
a start and end fence lines to delimit the code block.
A simple table looks like this:
| First Header | Second Header | Third Header |
|---|---|---|
| Content Cell | Content Cell | Content Cell |
| Content Cell | Content Cell | Content Cell |
If you wish, you can add a leading and tailing pipe to each line of the table:
| First Header | Second Header | Third Header |
|---|---|---|
| Content Cell | Content Cell | Content Cell |
| Content Cell | Content Cell | Content Cell |
Specify alignment for each column by adding colons to separator lines:
| First Header | Second Header | Third Header |
|---|---|---|
| Left | Center | Right |
| Left | Center | Right |
Don’t forget to check Preferences, lots of useful options are there.

此处如果把内容复制到“可视化”中，缩进会消失。Markdown文本应在“文本”中编辑。

好久没写过界面了，最近用最新的支援库，官方建议AppBar+ToolBar代替原ActionBar。然后翻了一下怎么往ToolBar上创建按钮，翻了半天没一个可以。。。最后发现把onCreateOptionsMenu丢了（网上的大爷们这么默契，全部都把这部分代码忽略掉真的好吗）。附上ToolBar上创建菜单的方法。
Activity中写入：
（XML方式）
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_check, menu);
return true;
}
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".CheckActivity">
<item android:id="@+id/action_controller"
android:title="@string/start"
android:orderInCategory="90"
app:showAsAction="always|withText" />
</menu>
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(Menu.NONE, Menu.FIRST + 1, 1, "设置")
.setIcon( android.R.drawable.ic_menu_help)
.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
return true;
}
菜单会显示在ToolBar右上角。setShowAsAction相当xml中的app:showAsAction。withText作用是把菜单的文字显示出来，如果想仅显示文字，不设置icon即可。
然后在onOptionsItemSelected中处理点击事件：
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.action_controller: // XML方式
Toast.makeText(MainActivity.this, "设置1", Toast.LENGTH_SHORT).show();
break;
case Menu.FIRST + 1: // Java代码方式，仅作示例，两种方法不应混用
Toast.makeText(MainActivity.this, "设置2", Toast.LENGTH_SHORT).show();
break;
}
return super.onOptionsItemSelected(item);
}

刚开始用gradle，临急抱佛脚，走了很多弯路。
下面有一个task hello：
task hello {
}
hello {
println 'Hello nothing1'
}
hello.doFirst {
println 'Hello first1'
}
hello << {
println 'Hello <<1'
}
hello.doLast {
println 'Hello last1'
}
hello << {
println 'Hello <<2'
}
hello {
println 'Hello nothing2'
}
hello.doFirst {
println 'Hello first2'
}
hello << {
println 'Hello <<3'
}
hello.doLast {
println 'Hello last2'
}
hello << {
println 'Hello <<4'
}
他的执行结果是：
Hello nothing1
Hello nothing2
Hello first2
Hello first1
Hello <<1
Hello <<2
Hello last1
Hello <<3
Hello <<4
Hello last2
Hello <<5
由此可以得出：
task内顺序：
doFirst块，且后定义的先执行
doLast块（<<等同于doLast，属于简写），且先定义的先执行
这里我写了一个task bye，并dependsOn hello，其余和hello一样。
结果是：
Hello nothing1
Hello nothing2
Bye nothing1
Bye nothing2
Hello first2
Hello first1
Hello <<1
Hello <<2
Hello last1
Hello <<3
Hello <<4
Hello last2
Hello <<5
Bye first2
Bye first1
Bye <<1
Bye <<2
Bye last1
Bye <<3
Bye <<4
Bye last2
Bye <<5
结果是：
先执行各个task的init块，再根据task之间依赖关系顺序执行
