<link href="http://zhongdechan.github.io/blog/2012/10/12/showmodaldialog-chrome/"/>

<id>http://zhongdechan.github.io/blog/2012/10/12/showmodaldialog-chrome</id>
<content type="html"><![CDATA[<p>在Chrome浏览器下调用window.showModalDialog 会忽略dialogWidth和dialogHeight属性,其他浏览器IE,firefox却显示正常。<br/>
原因是Chrome下dialogWidth和dialogHeight的值<strong>不能带”px”后缀</strong>.正确写法<code>"dialogWidth:100;dialogHeight:200"</code> <br/>
但其他浏览器则相反需要带有”px”后缀,例如:<code>"dialogWidth:100px;dialogHeight:200px"</code></p>
<p>要兼容所有浏览器需要判断浏览器类型，参考代码：</p>

<li><strong>Mountain Lion 编译报错extconf.rb:21:in `<main>‘: Only Darwin systems</strong></li>
</ul>
<p>Mountain Lion执行bundle install的时候，会给出下面的报错:</p>

<p>这个报错的原因是octopress需要的<code>rb-fsevent</code>的版本是<code>0.4.3.1</code>，这个版本还不支持<code>Mountain Lion</code>。
简单的处理办法是修改~/.rvm/gems/ruby-1.9.3-p194/gems/rb-fsevent-0.4.3.1/ext/extconf.rb文件，找到19行，如下:</p>

<link href="http://zhongdechan.github.io/blog/2012/03/21/dell-vostro-v131-mac-lion/"/>
<updated>2012-03-21T20:29:00+08:00</updated>
<id>http://zhongdechan.github.io/blog/2012/03/21/dell-vostro-v131-mac-lion</id>
<content type="html"><![CDATA[<p>安装黑苹果真的很折腾，近来同事在v131上完美安装了lion，足足花了一天，不断的重启不断滴尝试。建议想用苹果的还是直接买白苹果省心。</p>
<h3>安装情况</h3>
<p>CPU:Core i3 （完美）
主板: Intel HM 55 （完美）
显卡:HD Graphics 3000 （QE/CI完美）
声卡 （完美无爆音）
集成 摄像头/Mic （完美）
2x USB 3.0 （完美）
1 USB 2.0 （完美）
触摸板：（两点触摸 完美）
SD Card reader(完美)
蓝牙(无驱动)
WiFi(无驱动) 这款卡太老，没驱动的，建议买个usb网卡替代。<a href="http://www.360buy.com/product/389343.html">EDUP EP-N8513 隐藏型无线网卡</a></p>
<!--more-->
<h3>安装注意事项</h3>
<p>安装基础教程这里就不说了，pcbeta上有写得非常好的 。<a href="http://bbs.pcbeta.com/viewthread-920341-1-1.html">lion图文详细安装教程</a></p>
<p>这里指出这款机器安装的特别要注意的地方(10.8支持很好，不需以下步骤)
1. 保证所有硬盘卷轴不能有中文，不然会导致安装界面鼠标键盘不能用
2. 如果安装界面usb鼠标键盘仍然不能用，把/System/Library/Extensions/AppleIntel<strong> 、 Ati<em> 、Geforce</em></strong> 和 NV** 驱动都删掉
3. 安装的时候usb要用左边的usb2.0接口，右面的usb3.0接口要进入系统后安装相应驱动才能使用
4. 使用-f -v -x进入</p>
<p><em>经同事的不懈努力测试，按上面方法，系统绝对能正常安装。</em></p>
<p>安装好后第一件事就是把AppleIntel驱动放到/System/Library/Extensions，<strong>但严重注意这些驱动不是安装盘的AppleIntel</strong>
去pcbeta上搜索一下lion的原版驱动，必须包含AppleIntelHD3000Graphics**开头的驱动（安装盘上没这些，正常不删文件安装是有这些驱动的）</p>
<h3>必备软件</h3>
<ol>
<li><a href="http://support.apple.com/kb/DL1484">10.7.3 Combo Update</a> (升级包)</li>
<li><a href="http://www.tonymacx86.com/C:Dq-OCPpT/MultiBeast-4.3.1.zip">MultiBeast-4.3.1 for lion</a> （驱动包）</li>
<li>Kext Utility (驱动权限重建MultiBeast自带)</li>
<li>SleepEnabler.kext 解决睡眠问题</li>
<li>VoodooBattery.kext 电池显示</li>
</ol>
<h3>驱动安装</h3>
<ul>
<li>先安装<em>10.7.3 Combo Update</em> ，安装完后<strong>不要重启!!</strong></li>
<li>运行MultiBeast,选择下面提到的驱动</li>
</ul>

<ul>
<li><p>安装睡眠和电池驱动
SleepEnabler.kext和VoodooBattery.kext</p></li>
<li><p>使用Kext Utility重建缓存</p></li>
<li>重启，使用-f参数</li>
</ul>
<p>按上面的步骤重启后，系统声卡、显卡、网卡、usb3.0都能驱动的了。</p>
<p>现在右侧的USB3.0接口可以完美使用了，但是左侧的USB2.0却不能使用。
要驱动左侧的USB2.0和SD读卡器，需要删除AppleHPET.kext（<strong>要备份</strong>，这个在我机器上有效，其他机器不一定）</p>
<h3>显示器亮度</h3>
<p>安装好的系统不能调节亮度，需要在dsdt上添加几行代码
推荐使用dsdt editor 导出dsdt，该软件能自动fix错误和编译。
在dsdt中搜索PWRB ，添加以下这个Device (PNLF)方法，原来的内容不要删</p>
<figure class='code'><figcaption><span></span></figcaption><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>

</span><span class='line'> <span class="o">}</span>
</span><span class='line'><span class="o">}</span>
</span></code></pre></td></tr></table></div></figure>
<p>编译后把dsdt.aml放到/Extra下，重启就可以在显示器里调节亮度了,不过每次重启后又要重新调节。
不要用ACPIBacklight.kext，用了反而调节不了。不知道为何·~求解~~</p>

<p>这个很容易解决，很多人认为是Log4j问题，其实不是。
之前的项目运行过 <em>grails install-templates</em> 命令，在生成的web.xml下添加了内容。
新版本的grails修改过默认web.xml的内容，因此与现在的web.xml冲突。
解决办法是先把目前的web.xml文件备份并删除 ，运行一次 <em>grails install-templates</em> 命令生成新的web.xml
再把新增的内容手动添加上去</p>

<content type="html"><![CDATA[<p>今天把老项目Grails1.1升级到Grails2.01，出现奇怪的错误</p>
<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
</pre></td><td class='code'><pre><code class=''><span class='line'> XXXController.groovy: The [someAction] action accepts a parameter of type [EventTypeEnum]
</span><span class='line'> which does not appear to be a command object class. This can happen if the source code for this class is not in
</span><span class='line'> this project and the class is not marked with @Validateable.</span></code></pre></td></tr></table></div></figure>
<p>查了一下文档，原来grails2.x把Controller里面的所有public方法都会发布为action。
grails1.x Controller的action写法必须为</p>
<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
</pre></td><td class='code'><pre><code class=''><span class='line'>def exportExcelSingle = {
</span><span class='line'> ...
</span><span class='line'>}</span></code></pre></td></tr></table></div></figure>
<p>而grails2.x公共方法也会发布为actiong，上面写法等同于</p>
<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
</pre></td><td class='code'><pre><code class=''><span class='line'>public void exportExcelSingle = {
</span><span class='line'> ...
</span><span class='line'>}</span></code></pre></td></tr></table></div></figure>
<p>修复方法很简单，把public或者def开头的这些私有方法，声明为 <strong>private</strong> 就ok</p>

<content type="html"><![CDATA[<p>Mac连接samba或者windows共享，一般方法直接在Finder —前往—连接服务器。中输入”smb://ServerIpAddress“ 就可以了。
今天连接一个新建的samba服务器，怎么连接也提示密码错误！
原来是由于Samba 配置文件里面的 “netbios name” 名称太长，引起的。
详细参考<a href="http://blog.sonitech.org/2011/05/04/%E8%A7%A3%E5%86%B3-mac-%E8%BF%9E%E6%8E%A5-samba3-%E7%9A%84%E9%97%AE%E9%A2%98/">连接</a></p>

<content type="html"><![CDATA[<p>今天遇到个奇怪问题，系统用webservice 接收请求，然后调用电信的宽乐网关接口发送短信。
系统编码已经统一为UTF-8，服务器为Ubuntu。系统日志编码正常，但手机接收到的中文短信为乱码。
JAVA_OPTS设置为-Dfile.encoding=UTF8和-Dfile.encoding=GBK还是不行。
最后设置为 <strong>-Dfile.encoding=EUC-CN</strong> 竟然奇迹地成功了 ，运行一切正常。</p>

<link href="http://zhongdechan.github.io/blog/2011/01/11/twitter-bootstrap-ie7-break-line/"/>

<id>http://zhongdechan.github.io/blog/2011/01/11/twitter-bootstrap-ie7-break-line</id>
<content type="html"><![CDATA[<p>twitter bootstrap2.0有一个bug，在html上添加注释会引起断行（IE7下，IE8，9没问题）
例如以下官方代码:</p>
<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
<span class='line-number'>4</span>
<span class='line-number'>5</span>
<span class='line-number'>6</span>
</pre></td><td class='code'><pre><code class=''><span class='line'><div class="container-fluid">
</span><span class='line'> <div class="row-fluid">
</span><span class='line'> <div class="span4">first</div>
</span><span class='line'> <div class="span8">second</div>
</span><span class='line'> </div>
</span><span class='line'></div></span></code></pre></td></tr></table></div></figure>
<p>效果为显示一行，左侧显示first字符，右侧显示second字符，非常简单。但如果添加注释，就发生问题了。</p>
<figure class='code'><div class="highlight"><table><tr><td class="gutter"><pre class="line-numbers"><span class='line-number'>1</span>
<span class='line-number'>2</span>
<span class='line-number'>3</span>
<span class='line-number'>4</span>
<span class='line-number'>5</span>
<span class='line-number'>6</span>
</pre></td><td class='code'><pre><code class=''><span class='line'><div class="container-fluid">
</span><span class='line'> <div class="row-fluid"><!--顶部logo-->
</span><span class='line'> <div class="span4">first</div>
</span><span class='line'> <div class="span8">second</div>
</span><span class='line'> </div>
</span><span class='line'></div></span></code></pre></td></tr></table></div></figure>
<p>在row-fluid后添加注释<!—顶部logo—>,在IE7下运行显示first和second各自一行了！
以上测试环境在IETester上测试，没在纯IE7下使用过。</p>
