I'm writing a very long document in LaTeX. I have my work computer and my laptop, and I work on them both. I need to keep all the files synchronized between the two computers, and also would like to keep a revision history. I chose git as my DVCS, and I'm hosting my repository on my server. I'm also using Kile + Okular to do the editing. Kile doesn't have an integrated git plugin. I'm also not collaborating with anyone on this text. I'm also thinking about putting another private repository on codaset, if my server for some reason is not accessible.

在这种情况下，推荐的工作流实践是什么?如何在这个工作方案中进行分支?是否有一种方法可以比较同一文件的两个版本?用藏东西怎么样?

当文本被设置为属性时，我如何添加换行符:

<TextBlock Text="Stuff on line1 \n Stuff on line2" />

把它分解成分解格式不适合我的特殊情况。我需要的是一些方法来模仿以下:

<TextBlock>
  <TextBlock.Text>
    Stuff on line1 <LineBreak/>
    Stuff on line2
  </TextBlock.Text>
<TextBlock/>

Android系统中是否有一种方法可以检测软件(也就是Android。“软”)键盘在屏幕上可见吗?

您是否需要处理对象并将其设置为null，或者当它们超出作用域时，垃圾收集器将清理它们?

乳胶源代码清单应该是什么样的，才能产生像已知书籍中那样的输出，例如Spring Framework的输出?我已经尝试了乳胶列表包，但不能产生一些看起来像下面一个。因此，我主要对生成如下示例的格式说明感兴趣(来自Manning的Spring in Action示例章节):

编辑 在Tormod Fjeldskår的帮助下，这里是完整的代码片段，以产生所需的外观:

\usepackage{listings}
\usepackage{courier}
\lstset{
    basicstyle=\footnotesize\ttfamily, % Default font
    % numbers=left,              % Location of line numbers
    numberstyle=\tiny,          % Style of line numbers
    % stepnumber=2,              % Margin between line numbers
    numbersep=5pt,              % Margin between line numbers and text
    tabsize=2,                  % Size of tabs
    extendedchars=true,
    breaklines=true,            % Lines will be wrapped
    keywordstyle=\color{red},
    frame=b,
    % keywordstyle=[1]\textbf,
    % keywordstyle=[2]\textbf,
    % keywordstyle=[3]\textbf,
    % keywordstyle=[4]\textbf,   \sqrt{\sqrt{}}
    stringstyle=\color{white}\ttfamily, % Color of strings
    showspaces=false,
    showtabs=false,
    xleftmargin=17pt,
    framexleftmargin=17pt,
    framexrightmargin=5pt,
    framexbottommargin=4pt,
    % backgroundcolor=\color{lightgray},
    showstringspaces=false
}
\lstloadlanguages{ % Check documentation for further languages ...
     % [Visual]Basic,
     % Pascal,
     % C,
     % C++,
     % XML,
     % HTML,
     Java
}
% \DeclareCaptionFont{blue}{\color{blue}} 

% \captionsetup[lstlisting]{singlelinecheck=false, labelfont={blue}, textfont={blue}}
\usepackage{caption}
\DeclareCaptionFont{white}{\color{white}}
\DeclareCaptionFormat{listing}{\colorbox[cmyk]{0.43, 0.35, 0.35,0.01}{\parbox{\textwidth}{\hspace{15pt}#1#2#3}}}
\captionsetup[lstlisting]{format=listing,labelfont=white,textfont=white, singlelinecheck=false, margin=0pt, font={bf,footnotesize}}

在你的文档中使用它:

\lstinputlisting[label=samplecode, caption=A sample]{sourceCode/HelloWorld.java}

如何在IPython Notebook中显示LaTeX代码?

如何将整个文档的字体更改为sans-serif(或其他任何东西)?

假设我想对arr中的每个元素求和。

arr = [ { x: 1 }, { x: 2 }, { x: 4 } ];
arr.reduce(function(a, b){ return a.x + b.x; }); // => NaN

我有理由相信a。x在某些时候是没有定义的。

以下工作正常

arr = [ 1, 2, 4 ];
arr.reduce(function(a, b){ return a + b; }); // => 7

第一个例子中我做错了什么?

filter, map和reduce在python2中完美地工作。这里有一个例子:

>>> def f(x):
        return x % 2 != 0 and x % 3 != 0
>>> filter(f, range(2, 25))
[5, 7, 11, 13, 17, 19, 23]

>>> def cube(x):
        return x*x*x
>>> map(cube, range(1, 11))
[1, 8, 27, 64, 125, 216, 343, 512, 729, 1000]

>>> def add(x,y):
        return x+y
>>> reduce(add, range(1, 11))
55

但在Python 3中，我收到以下输出:

>>> filter(f, range(2, 25))
<filter object at 0x0000000002C14908>

>>> map(cube, range(1, 11))
<map object at 0x0000000002C82B70>

>>> reduce(add, range(1, 11))
Traceback (most recent call last):
  File "<pyshell#8>", line 1, in <module>
    reduce(add, range(1, 11))
NameError: name 'reduce' is not defined

如果有人能给我解释一下这是为什么，我会很感激。

默认情况下(使用普通样式)BibTeX按字母顺序排序引用。

如何按文献中出现的顺序排列引文?
