eclipseRoot = eclipseRoot.replace("file:/", "");

Eclipse插件获取Workspace根目录

//方法1
String workspaceRoot= Platform.getInstanceLocation().getURL().toString();
workspaceRoot = workspaceRoot.replace("file:/", "");

String path = Activator.getDefault().getStateLocation().makeAbsolute().toFile().getAbsolutePath();

Eclipse插件获取User根目录

String userHome = Platform.getUserLocation().getURL().toString();
userHome = userHome.replace("file:/", "");

Elclipse插件获取Bundle的OSGI路径

//方法1
String bundlePath = Activator.getDefault().getBundle().getLocation();

//方法2
Bundle bundle = Platform.getBundle("bundle id");
URL urlentry = bundle.getEntry("bundle resource path");
String strEntry = FileLocator.toFileURL(urlentry).getPath();

//方法3

1. Download source code from Eclipse.
For example, I used this one:

From here: http://download.eclipse.org/jetty/
Get this one: jetty-8.1.15.v20140411

2. Read this:

http://docs.codehaus.org/display/JETTY/Building+from+Source

3. Prepare JDK and Maven:

SET JAVA_HOME=C:\Languages\Java\JDK\jdk_x86_1.6.0_34
SET MAVEN_HOME=C:\Languages\Java\JavaTools\apache-maven-3.0.4
SET PATH=%MAVEN_HOME%\bin;%JAVA_HOME%\bin;%PATH%
CMD

4. Run “mvn install”

5. Use eclipse to import maven project

JS钩子示例

Posted on by — No Comments ↓ 
// JS钩子示例
// JS对于不同消息类型，实现了不同的调用链
// 事件触发的时候，根据消息类型，调用对应的调用链
// 同一个钩子函数，安装多次，会根据安装顺序，调用多次
// 可以对比Windows API的钩子如SetWindowsHookEx等，原理上很相似

// 储存全部事件的调用链函数列表
function hooks() {
    this.queue = new Array();
}

// 通过addAction，生成调用链
hooks.prototype.addAction = function (hook, func) {
    // 某一个事件的调用链函数列表
    if(this.queue[hook]==undefined){
        this.queue[hook] = new Array(); 
    }
    
    if (typeof func == 'function') {
        this.queue[hook].push(func);
    } else if (typeof func == 'string') {
        this.queue[hook].push(this.window[func]);
    }
}

// 通过doAction，实现调用链
hooks.prototype.doAction = function (hook) {
    var parameters = Array.prototype.slice.call(arguments, 1); 
    var functions = this.queue[hook]; 
    for (var i = 0; i < functions.length; i++) {
        this.call_user_func_array(functions[i], parameters);
    }
    return true;
}

// 实现具体钩子函数调用
hooks.prototype.call_user_func_array = function(cb, parameters) {
    if (typeof cb === 'string') {
        func = (typeof this[cb] === 'function') ? this[cb] : func = (newFunction(null, 'return ' + cb))();
    } else if (cb instanceof Array) {
        func = (typeof cb[0] == 'string') ? eval(cb[0] + "['" + cb[1] + "']") : func = cb[0][cb[1]];
    } else if (typeof cb === 'function') {
        func = cb;
    } if (typeof func != 'function') {
        throw new Error(func + ' is not a valid function');
    } if (typeof parameters == 'undefined') {
        var tmp_ary = [];
        var parameters = Array.prototype.slice.call(tmp_ary, 1);
    } return (typeof cb[0] === 'string') ? func.apply(eval(cb[0]), parameters) : (typeof cb[0] !== 'object') ? func.apply(null, parameters) : func.apply(cb[0], parameters);
}

function func1() {
    console.log("func1");
}

function func2() {
    console.log("func2");
}

function func3() {
    console.log("func3");
}

// 使用示例
var myhook = new hooks();
myhook.addAction("loaded", func3);
myhook.addAction("loaded", func2);
myhook.addAction("loaded", func1);
myhook.addAction("loaded", func3);
myhook.doAction("loaded")

Build Tomcat Lesson101

1. Download one source tag from Apache
For example, I used this tag:

http://svn.apache.org/repos/asf/tomcat/tc6.0.x/tags/TOMCAT_6_0_41

2. Read this: 

http://tomcat.apache.org/tomcat-6.0-doc/building.html

3. Prepare JDK and Ant

SET JAVA_HOME=C:\Languages\Java\JDK\jdk_x86_1.6.0_34
SET ANT_HOME=C:\Languages\Java\JavaTools\apache-ant-1.9.0
SET PATH=%ANT_HOME%\bin;%JAVA_HOME%\bin;%PATH%
CMD

4. Copy build.properties.default to build.properties

5. Edit build.properties and set base.path

base.path=the path to store thirdpart libs

6. Run “Ant download”

7. Run “Ant”

8. Rename files

move eclipse.classpath .classpath
move eclipse.project .project

9. Use eclipse to import this project

10. Set break point and debug

VS2013编译VS2010的CPP项目出错

Posted on by — No Comments ↓

前一阵子重装了电脑，很多编译环境都丢失了，各种悲剧不说，还有一些奇奇怪怪的错误

我以前有一个VS的项目，初始是2010sp1的VC本地项目，后来升级到VS2013
但一直没时间去处理兼容性问题，就没有将项目升级到2013的格式
相当于用2013在编译2010的工程，好在是相安无事。

现在重装了，我准备重新编译一下，结果VS2013告诉我Windows SDK配置错误

warning MSB8003: Could not find WindowsSDKDir variable from the registry. TargetFrameworkVersion or PlatformToolset may be set to an invalid version number.

在网上找了很久，解决方法就两种，一是修改注册表，一是安装对应版本的SDK。
尝试了修改注册表，但没有效果，还是同样的错误。
由于时间很紧迫，一怒之下安装了VS2010+SP1，结果就好了。

现在的注册表为：

其实在此前，我已经安装了Windows SDK7.1，应该是可以编译的，不知道为什么。。。
当时时间紧迫，没能细究。
希望我现在的注册表配置，能给大家提供参考。。。

iPhone4和耳机一起挂了

Posted on by — No Comments ↓

我可怜的iPhone耳机，上个月开始一直就不太稳定，经常插上后，会自动将音量调到最大，感觉线控挂掉了
但后来，有时候又是好的，而且再买一个也挺贵的，于是就凑合着用了

估计是我周日洗澡的时候，iPhone放到一边，进水了，然后后续的悲剧就开始了
周日晚上开始狂发热，开始还以为是散热不好，但出现了两次手机温度过高的画面后，我意识到，貌似进水啦。。。

周一发现，耗电好厉害。。。
充电一晚，到100%，周二上班。。。
打了30分钟电话，电量只有30%，然后，半个小时以内，电量耗尽，中午的时候，早已经关机啦

尝试了好多次，一直没法充电成功。。。

由于开机工具没在身边，只好回去再处理一下啦。。。

由于MI2S也在刷机，中间出现了几次没有手机可用的窘境。。。

悲剧啊。。。

希望过一阵子可以搞好。。。

小米2S刷Android4.4.4

Posted on by — No Comments ↓

上周末，本来的工作任务取消了，于是开始了痛苦的刷机历程

开始折腾。。。

1、在小米论坛，找到了秋大的Android自用版4.4.4
2、准备开始卡刷，但发现上次刷了4.1版本，无论如何都进不了Recovery，只能进Fastboot模式
3、只好下载了MIUI的最新版本，线刷到手机中
4、MIUI好了，就开始找第三方的Recovery，找了两个都不好用，最后用秋大的版本是OK的
5、然后将Android4.4.4卡刷到系统2
6、开机，OK
7、开始增加Google服务，但找了几个包刷进去都不行，就只好找了gapps，在Recovery下刷入
8、重启后，无法登陆Google账号，SSH和VPN都不行，悲剧啊

继续折腾。。。

各种尝试后，不小心进入了系统1，MIUI进不去，然后重启到系统2，Android也进不去啦。。。
后来发现是关闭了双系统兼容，所以只好将用户数据全部删除了，重新进入到系统2。。。
然后，Android让我登录Google账号

老子在PRC，不翻墙，哪里上的去Google账号啊，你大爷的。。。
最后，灵机一动，用iPhone4的热点，代理Andoird穿墙。。。
折腾了好几次，终于好了。。。

好消息是，我登上Google账号了。。。
坏消息是，居然没有联系人同步。。。
你大爷的。。。

最后分析，应该是ROM的作者，把Exchange账号类型干掉了，为了给ROM减肥，你至于吗。。。
没办法，只好用很傻很天真的QQ通讯录，真心不专业啊。。。

继续折腾。。。

开始安装APP，用SSH下载软件，下了整整两天，那叫个慢，你大爷的。。。

我的周末就这样过去了，真是一个超(no)级(zuo)充(no)实(die)的周末啊

Fix Android “Too Many Pattern Attempts”

Posted on by — No Comments ↓

前几天外出时，Android手机放口袋里，不知道怎么碰到了，超过了解锁图案的最大重试次数，屏幕上显示“Too Many Pattern Attempts”，还要我登录Google账号。

Google账号我能登录，但问题是，Google最近被封掉了，根本连不上啊。

经过查找，发现有两种方法可以解决这个问题，一种是直接重置手机，后果是资料全没；一种是用ADB方法，跳过验证。

手机资料全清空，当然是不可以接受的！于是就使用了ADB方法。

前提是：
1、手机root过
2、ADB调试功能打开

连线，执行下面的命令：

adb root
adb shell
rm /data/system/gesture.key

这样，重启后，就可以跳过图形验证，直接进入设置界面了。

然后，开SSH，登录Google账号，重置图形验证，搞定！
