		<description><![CDATA[Homeland第一季已经播了10集，说是还有两集这季就完了。第二季啥时候放还不知道。 CIA内部肯定有叛徒。这家伙害死了Lynne Reed（线人，沙特王子女友），放跑了Raqim（那个副教授），炸死了外交官。 如果他不准备在这一季暴露的话，有可能是还没有出现的人物，也就没办法猜了。否则，应该是已经出场的人物，而已经出场的CIA官员并不是太多。 根据Aileen Morgan接到的提醒电话，可以排除所有的女性（当然也有可能不是内奸直接打的电话，但是从Aileen接电话的情况看，这人是第一次打电话过来，所以很可能是内奸本人迫不得已直接打的电话）。已经出场的男性CIA官员主要有David（头儿），Saul，Danny Galvez（分析员，给Carrie开过几次车，站在Raqim家屋顶瞭望的那位），以及安装监听设备的一老一少。 安装监听设备的一老一少好象不是正式工，级别太低，不可能接触核心秘密，可以排除。Saul和Danny也可以排除，主要原因是Danny在Raqim家屋顶搜查无果时，Saul指示Danny使用望远镜瞭望，从而发现疑点，线索转向狙击手。如果两人有一人是内奸，不太可能找到这个疑点。 剩下的只有David了。不管什么线索，只有Carrie和Saul知道的时候，啥事儿没有，时不时有些进展。只要让David知道了，就会出意外。另外，David还让Brody见了那个看守，把刀片给了他。 想来想去，内奸最有可能是David。<table class="wumii-related-items" cellspacing="0" cellpadding="3" border="0"  style="clear: both;">

			<content:encoded><![CDATA[<p><a href="http://www.sho.com/site/homeland/home.sho">Homeland</a>第一季已经播了10集，说是还有两集这季就完了。第二季啥时候放还不知道。</p>
<p>CIA内部肯定有叛徒。这家伙害死了Lynne Reed（线人，沙特王子女友），放跑了Raqim（那个副教授），炸死了外交官。</p>
<p>如果他不准备在这一季暴露的话，有可能是还没有出现的人物，也就没办法猜了。否则，应该是已经出场的人物，而已经出场的CIA官员并不是太多。</p>
<p>根据Aileen Morgan接到的提醒电话，可以排除所有的女性（当然也有可能不是内奸直接打的电话，但是从Aileen接电话的情况看，这人是第一次打电话过来，所以很可能是内奸本人迫不得已直接打的电话）。已经出场的男性CIA官员主要有David（头儿），Saul，Danny Galvez（分析员，给Carrie开过几次车，站在Raqim家屋顶瞭望的那位），以及安装监听设备的一老一少。</p>
<p>安装监听设备的一老一少好象不是正式工，级别太低，不可能接触核心秘密，可以排除。Saul和Danny也可以排除，主要原因是Danny在Raqim家屋顶搜查无果时，Saul指示Danny使用望远镜瞭望，从而发现疑点，线索转向狙击手。如果两人有一人是内奸，不太可能找到这个疑点。</p>
<p>剩下的只有David了。不管什么线索，只有Carrie和Saul知道的时候，啥事儿没有，时不时有些进展。只要让David知道了，就会出意外。另外，David还让Brody见了那个看守，把刀片给了他。</p>
<p>想来想去，内奸最有可能是David。</p>

		<description><![CDATA[Automatic (La)TeX Plugin for Vim (atp-vim)是一个新的支持LaTeX的插件。前些天刚发现时，bug还比较多，经常出错，现在的版本好多了。与latexsuite相比，有些新的功能很不错（毕竟06年以后latexsuite就没有更新过），推荐给喜欢LaTeX，VIM，Python的朋友。 完整的特性可以查阅官方的Feature List，或者手册。下面几条是我比较喜欢的。 正向查找。由vim中光标处直接跳至pdf相应位置处。 反向查找。由pdf跳转至vim相应源代码处。 清理中间文件。这个功能实现起来不难，但是有了总是方便一点，特别是对有洁癖的人。 补全命令也很丰富。 总的来说，值得一试。 ps. 目前最新的测试版是9.6.7。从SF的记录来看，最早的版本是今年3月份发布的，上来就是9.1。莫非现在流行大版本号？ 7月11日补充：如果源文件所在目录的路径中包含中文，则会出现很多问题，而且很诡异。<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">

			<content:encoded><![CDATA[<p><a href="http://atp-vim.sourceforge.net/requirements.shtml">Automatic (La)TeX Plugin for Vim (atp-vim)</a>是一个新的支持LaTeX的插件。前些天刚发现时，bug还比较多，经常出错，现在的版本好多了。与latexsuite相比，有些新的功能很不错（毕竟06年以后latexsuite就没有更新过），推荐给喜欢LaTeX，VIM，Python的朋友。</p>
<p>完整的特性可以查阅官方的<a href="http://atp-vim.sourceforge.net/features.shtml">Feature List</a>，或者<a href="http://atp-vim.sourceforge.net/automatic-tex-plugin.html">手册</a>。下面几条是我比较喜欢的。</p>
<ul>
<li>正向查找。由vim中光标处直接跳至pdf相应位置处。</li>
<li>反向查找。由pdf跳转至vim相应源代码处。</li>
<li>清理中间文件。这个功能实现起来不难，但是有了总是方便一点，特别是对有洁癖的人。</li>
<li>补全命令也很丰富。</li>
</ul>
<p>总的来说，值得一试。</p>
<p>ps. 目前最新的测试版是9.6.7。从SF的记录来看，最早的版本是今年3月份发布的，上来就是9.1。莫非现在流行大版本号？</p>
<p>7月11日补充：如果源文件所在目录的路径中包含中文，则会出现很多问题，而且很诡异。</p>

		<description><![CDATA[个人感觉Arch Linux是比较激进的一个发行版。早早将Python的默认版本升级到3.0，对待内核也是不留余地。内核文件不区分版本号，都叫kernel26.img，因此每次升级内核，都会将老内核文件覆盖。一旦新内核有问题，麻烦就大了。 今天一开机，习惯性的pacman -Syu，和往常一样，有若干软件包需要升级，直接确认升级。最后才注意到内核也升级了。重启后，卡在加载Alsa的那一步，无法进入系统。折腾了一上午，以下方法可以避免重装。 Arch Linux还是给自己留了一条后路。系统一般安装了lts版（应该是长期支持版本）的内核，也就是kernel-lts.img和vmlinuz26-lts，都在/boot目录下。如果没有安装这个包，建议立即安装，以备不时之需。可以在系统启动时，修改启动参数，选择使用lts版内核。Grub菜单出现后，按e修改启动参数，将kernel26.img换成kernel26-lts.img，将vmlinuz26换成vmlinuz26-lts，按b启动即可。或者在系统还是正常的时候，修改/boot/grub/menu.lst文件增加一个使用lts内核的启动项。 如果已经进不了系统，也没有安装lts内核，用Arch Linux系统盘启动或者其他方式启动，想办法加载原系统的/分区，修改/etc/rc.conf文件，将启动时报错的服务禁用后重启。我这次是alsa和hal与新内核不兼容，重启后进入系统。 后来在Arch Linux的wiki上看到另外一个方法：https://wiki.archlinux.org/index.php/Kernel_Panics_(%e7%ae%80%e4%bd%93%e4%b8%ad%e6%96%87)，但是我自己还没有尝试。 为了防止以后出现类似问题，可以将kernel26和kernel26-headers加入pacman.conf的忽略包列表，这样在使用pacman -Syu时，这两个包就不会被升级了。<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">

<p>=============================</p>
<p>周五晚将ubuntu 11.04换成Archlinux，速度有提升，但是太折腾。每项设置都要看着wiki，开着google。目前感觉最困难的是声音和打印机。</p>
<p>alsa折腾很久都没有声音，换oss。有声音了，还挺大，但是插上耳机没有用，还是用喇叭放。又换回alsa，莫明其妙好了，也不知道是哪个地方的设置起作用了。</p>
<p>打印机也很麻烦，什么hplip了，foo2zjs了，直接安装了，自己编译了，反正能查到的，能折腾的，都试了一遍。周六凌晨终于能够打印了。睡了一觉起来，打印机又不干活了。又折腾了一天，总算成功了。为了保险，将所有相关的程序都删除，再重新安装，确认没有问题。</p>
<p>关键的步骤有三点：1、第4步添加打印机时，只能用cups的web管理界面添加，不能用HP的管理程序添加。用HP的程序添加时，总是会卡在下载plugin那一步，无法下载。2、Model一定要选对，其他的不行，至少在我的机子上不行。3、第5步，Firmware一定要下载，不下载打印机不干活。</p>
<p>相信以上步骤对于其他发行版下安装HP打印机也有一定的参考价值。</p>
<p>PS：知道第一次安装、配置会很难，但是没想到这么难！现在我知道为什么装了Archlinux的人都说，装了一次，就不用重装了，折腾不起啊！</p>

<p>我的基本桌面系统是一个现代的Linux发行版，它默认使用utf-8。我把下面的命令添加到我的bashrc文件中（实际上是zshrc，但在bash中应该同样能用）。</p>
<p>function man<br />
{<br />
    /usr/bin/man $* | col -bp | iconv -c | view -c &#8216;set ft=man nomod nolist&#8217; -<br />
}</p>
<p>如果你用的是不支持utf-8的老系统，可以试试下面的命令：<br />
function man<br />
{<br />
    /usr/bin/man $* | col -b | view -c &#8216;set ft=man nomod nolist&#8217; -<br />
}</p>
<p>注意，上面的函数可能会修改你的shell.</p>

			<content:encoded><![CDATA[<p>今天早上一个朋友让我写一个Vim宏，保留双引号中的内容，而删除其余的所有文本。比如文件内容像这样：<br />
Automotive<br />
Banking<br />
Biotech<br />
……<br />
处理后，应该是这样<br />
Automotive<br />
Banking<br />
Biotech<br />
……<br />
开始，我用下面的序列（忽略了保存宏的命令）<br />
df&#8221;f&#8221;d$j0 （9个字符）<br />
效果不错，不过我还想改的更短一些：<br />
df&#8221;f&#8221;D+ （7个字符）<br />
我想，这应该是我能想到的最短的方案了，但是：<br />
df&#8221;wD+ （6个字符）<br />
这个是最短的，但是我希望我是错的。</p>
<p>更新：<br />
我的朋友Chris Sutter提出了另外一种方案：<br />
di&#8221;Vp (5个字符）<br />
或者如果你还想跳到下一行：<br />
di&#8221;Vgp （6个字符）</p>
<p>网友在评论中给出的其他解决方案：<br />
:%s/^.*&#8221;\(.*\)&#8221;.*$/\1/   （长了点，但是不需要宏）</p>

df&#8221;wD+这个有问题，当引号中的内容不是一个单词时，结果是错误的。</p>

			<content:encoded><![CDATA[<p>这是非常有用的一个功能，但是我一般只用于HTML和XML文件。</p>
<p>1、打开一个文件<br />
2、输入:filetype命令，确认是否indent选项是否为ON<br />
3、如果不是ON，使用:filetype indent on来打开<br />
4、按gg=G（不是ex模式），使用equalprg（默认是none）过滤整个文件<br />
5、如果想使用第三方的程序，可以设置equalprg：<br />
:setlocal equalprg=tidy\ -quiet\ -m\ -utf8\ %<br />
或者你想使用make而不是equalprg<br />
:setlocal makeprg=tidy\ -quiet\ -errors\ %<br />
这样可以直接:make</p>

		<description><![CDATA[Vim的Quickfix功能允许你建立一个项目列表，然后很方便的在列表中各项间跳转。一种向列表中添加新项目的快捷方法是使用Vim内置的grep功能。 :vimgrep /some pattern/somefile 执行上述命令后，在指定文件中匹配到的行会填充到quickfix列表中。这时，可以使用:cope打开quickfix缓存区。在quickfix缓存区中某一行上按回车，会打开相应的文件，并跳转到相应的行。 quickfix更多的是用于调试程序时，在多个文件间跳转。一个常用的debug技巧是在多条件判断语句中插入输出语句。如果符合&#8221;filename:line number:error message&#8221;这样的的格式，Vim就可以识别这些调试信息，并调入quickfix缓存。在Ruby中，你可以这样做： puts(&#8220;#{__FILE__}:#{__LINE__}:some error happened&#8221;) 在你需要跟踪的的文件中放置类似的语句，把输出信息保存到&#8221;debug.txt&#8221;文件中，打开Vim。使用:cfile debug.txt，Vim就会打开第一个错误所在的文件。也可以使用:cope命令浏览quickfix列表并且跟踪所有错误。 本篇来源：Daily Vim: Text Editor Tips, Tricks, Tutorials, and HOWTOs: Quickfix 注：更详细的说明和应用示例，请参考这篇中文Blog：vi/vim使用进阶: 剑不离手 – quickfix – 易水博客<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">
