Windows 2008 server 的shutdown event tracker对我这种常常重启的用户来说，就是一个额外的负担。可以用如下方法禁用：

运行 gpedit.msc，然后 “Computer Configuration - Administrative Templates - System”, 设置 Display Shutdown Event Tracker  为  disabled.

CMake 是一个跨平台的编译构建系统，它负责搜集系统中的函数库信息，管理源文件的依赖关系，生成合适的脚本供自动编译系统调用，完成程序的编译构建任务（compile and build）。它所能生成的格式包括常用的 Unix/Linux、Cygwin 以及 MinGW 下的 Makefile，Windows 下的 nmake 和 Visual Studio

CMake使用一个 CMakeList.txt 的输入文件，一个简单的例子如下：

cmake_minimum_required (VERSION 2.6)
project (HELLO)

# Recurse into the “Hello” and “Demo” subdirectories. This does not actually
# cause another cmake executable to run. The same process will walk through
# the project’s entire directory structure.
add_subdirectory (Hello)
add_subdirectory (Demo)

子目录 Hello 下有 CMakeList.txt 文件：

# Create a library called “Hello” which includes the source file “hello.cxx”.
# The extension is already found. Any number of sources could be listed here.
add_library (Hello hello.cxx)

子目录 Demo 下有 CMakeList.txt

# Make sure the compiler can find include files from our Hello library.
include_directories (${HELLO_SOURCE_DIR}/Hello)

# Make sure the linker can find the Hello library once it is built.
link_directories (${HELLO_BINARY_DIR}/Hello)

# Add executable called “helloDemo” that is built from the source files
# “demo.cxx” and “demo_b.cxx”. The extensions are automatically found.
add_executable (helloDemo demo.cxx demo_b.cxx)

# Link the executable to the Hello library.
target_link_libraries (helloDemo Hello)

通常的编译安装为：

cmake c:\devel\project-X -G “Visual Studio 9 2008″

然后用Visual studio打开生成的 solution 文件。

If you often look at files that are updated,  a log file for a running process, you’ll want to make sure you’re looking at the most recent version of the file.

To do this, add the following to your .emacs:

(global-auto-revert-mode 1)

For more documentation type:

C-h C-f global-auto-revert-mode RET

Life is like a searching algorithm, someone uses greedy searching, someone uses breadth-first searching, someone uses depth-frist searching. There are also ones using heuristic searching.

It has been years I have not touched Web server on Linux. There are new commands to release you from editing the *conf in /etc/apache2:

$sudo a2enmod userdir

then try this

<?php phpinfo(); ?>

See the results !

Use LaTeX equations as a png figure in OpenOffice:

1. produce tex file:

\documentclass{article}
\usepackage[active,tightpage,displaymath]{preview}
\begin{document}
\begin{preview}
f(x)=\sqrt{x}
\end{preview}
\begin{preview}
f(x)=e^{\sqrt{x}}
\end{preview}
\end{document}

2. compile tex file with latex and get dvi file.
3. dvipng -Ttight –depth –height -bg Transparent eq-preview

You will get a series of pictures

自作聪明有时候很麻烦：

Start / Run / gpedit.msc / Local Computer Policy / Computer Configuration / Administrative Templates / Windows Components / Windows Update / Re-prompt for restart with scheduled installations

搞定！
