那是我日夜思念深深爱着的人啊

到底我该如何表达

她会接受我吗

也许永远都不会跟她说出那句话

注定我要浪迹天涯

怎么能有牵挂

梦想总是遥不可及

是不是应该放弃

花开花落又是一季

春天啊你在哪里

青春如同奔流的江河

一去不回来不及道别

只剩下麻木的我

没有了当年的热血

看那满天飘零的花朵

在最美丽的时刻凋谢

有谁会记得这世界他来过

转眼过去 多年世间

多少离合悲欢

曾经志在四方少年

羡慕南飞的雁

各自奔前程的身影

匆匆渐行渐远

未来在哪里平凡

啊 谁给我答案

那时陪伴我的人哪

你们如今在何方

我曾经爱过的人啊

现在是什么模样

当初的愿望实现了吗

事到如今只好祭奠吗

任岁月风干理想再也

找不回真的我

抬头仰望这漫天星河

那时候陪伴我的那颗

这里的故事

你是否还记得

生活像一把无情刻刀

改变了我们模样

未曾绽放就要枯萎吗

我有过梦想

青春如同奔流的江河

一去不回来不及道别

只剩下麻木的我

没有了当年的热血

看那满天飘零的花朵

在最美丽的时刻凋谢

有谁会记得这世界他曾经来过

当初的愿望实现了吗

事到如今只好祭奠吗

任岁月风干理想再也

找不回真的我

抬头仰望这漫天星河

那时候陪伴我的那颗

这里的故事

你是否还记得

如果有明天

祝福你 亲爱的

http://spoiledmilk.dk/blog/html5-changing-the-browser-url-without-refreshing-page参考文档： 

https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history#section_4An often overlooked feature of HTML5 is the new “onpopstate” event.This new feature offers you a way to change the URL displayed in the browser* through javascript without reloading the page. It will also create a back-button event and you even have a state object you can interact with.This means you won’t have to use the hash-hack anymore if you want add state to your AJAX-application, and search engines will be able to index your pages too.So how does it work? Well, it’s fairly simple. In Chrome you write:window.history.pushState(“object or string”, “Title”, “/new-url”);Executing this line of code will change the URL to my-domain.com/new-url (3rd option). The “Title” string (2nd option) is intended to describe the new state, and will not change the title of the document as one might otherwise expect. The 

W3 documentation states:>“Titles associated with session history entries need not have any relation with the current title of the Document. The title of a session history entry is intended to explain the state of the document at that point, so that the user can navigate the document’s history.”

So if you want the document’s title to change to match the title of the history entry, you’ll need to write a hook for that (hint: just tie a function to the onpopstate event). Finally, “object or string” (1st option) is a way to pass an object to the state which you can then use to manipulate the page.You can programmatically invoke the back-function by running:window.history.back();And you can of course go forward too:window.history.forward();Or even go to a specific history state:window.history.go(2);The object you pass as the first option to the pushState function will stay with each state, so if you go back in the history, you’ll get the object for that state. If you need to manipulate a state (instead of creating a new one) you can use:window.history.replaceState(“object or string”, “Title”, “/another-new-url”);Note that while this will change the URL of the page, it will not allow the user to click the back-button to go back to the previous state because you’re replacing the current state, not adding a new one. So, this is the correct behaviour.Personally, I think the URL should be the first parameter and then the two other options should be optional. Regardless, this feature will certainly come in handy when working with AJAX- and Flash-applications that need state (read: bookmarkable pages and back-button support). Anyone looking to make their Flash- or AJAX-application indexable by search engines so they will get better raking in Google and the likes, should also have a look at this new feature.The most prominent implementation of this HTML5-feature that I’ve seen is in the new Flickr layout. Here’s an 

example page (remember to enable the new layout if you haven’t already). Now, if you’re using the latest version of Chrome or Safari and click one of the sets, e.g. “Strobist”, it will slide open and the URL will change but you’ll notice that the page doesn’t reload.It’s worth noting that Flickr uses replaceState instead of pushState – in other words, they don’t add a back-button event. I’m guessing they feel that switching back and forth between opened/closed sets is too small a change for a back-button event (I’d certainly agree with them on that decision), so instead they just replace the URL so if you copy/paste the link to a friend, they’ll see the exact same page that you did.Another interesting thing is how Flickr still use the old hash-hack as a fallback if you’re running on browsers that don’t support this new HTML5-feature. I predict/hope that a lot of the plugins that help you easily implement the hash-hack will bake this into their core so people with new browsers can start reaping the benefits.The latest versions of Chrome and Safari already have support for “onpopstate” and Firefox 4 will have support for it as well. Unfortunately, it seems like IE9 won’t be supporting this feature if we are to believe 

this Wikipedia article (“Trident” is IE’s layout engine).Check out the 

W3 specification for more info.* For security reasons, you can only change the path of the URL, not the domain itself. So you can change anything in the URL after my-domain.com/[change-the-stuff-here.html].

经过差不多两个星期的时间的折腾，我的Arduino电动滑板项目大有进展:) ，经过之前把轮胎与马达套合在一起这个难题解决，信心大增，而后做的轮胎支架还算过关，昨晚索性把电池用3M胶带绑在滑板上，接上控制盒，试滑了下，感觉还不错:) ##

It is fixed in https://review.source.android.com/16569. This change enables changing the ADT clasppath container’s source attachment and disables setting invalid source attachment. Hoping it will be available in ADT 8.0.0.Namely, ADT classpath container in 0.9.x has the source attachment set to the \platforms\android-\sources directory. This directory doesn't exist in standard SDK. Eclipse try to cache entries in this directory on every access and it slow up auto completion.

在MAC的系统偏好设置的节能器中有一个定时的功能，选中启动或唤醒，设置相应设置，如每天，上午7:30；这样MAC会在这个时间自动启动或唤醒，但要保证电源适醒器连在MAC上。

然后我们可以再设置一个程序在登陆时打开，如我将豆瓣电台设置为登陆时打开，这样，每天早上7:30时，伴随着豆瓣电台，我会从梦中醒来！

1、安装  sudo apt-get install git git-core2、git的初始设置  git config –global user.name “Your Name”  git config –global user.email miclle.zheng@gmail.com3、建立仓库  进入到项目目录。  git init  #这样在你的项目目录下就会有一个.git的隐藏目录（类似于.svn 但总个项目只会在项目根目录下有一个.git目录） 。4、初始化项目  git add .  #添加所有文件的情况，也可以添加特定的几个文件，比如git add README等等。  git commit -m ‘first commit’  #-m 参数以及后面的字符串是添加说明信息。5、 注册github账号，创建项目！6、创建SSH密匙  ssh-keygen -C ‘miclle.zheng@gmail.com’-t rsa  #确认使用默认路径，然后输入两次你要是用的密码就行，可以为空。  7、提交密匙  现在又要回到github的页面上，在“账户设置中”有一个“SSH 公匙”选择“添加新的公匙”。  填入标题，如”miclle@ubuntu”，或 “miclle.zheng@gmail.com”，work-pc都可以  公匙是刚刚上一步生成的一段代码  cd  #回到默认目录  cat .ssh/id_rsa.pub  #将里面的内容拷贝到“ 公匙”里，保存。  设置完成后可以通过下面命令测试连接  ssh -v git@github.com8、上传代码  git remote add origin git@github.com:miclle/test.git  git push -u origin master其它命令：创建和合并分支#git branch 显示当前分支是master 本地和远程合并，本地默认分支为master#git branch new-feature  创建分支# git checkout new-feature 切换到新分支提交到本地GIT# git commit -a -m “message…“合并到远程服务器# git push origin new-feature如果new-feature分支成熟了，觉得有必要合并进master#git checkout master更新本地master#git pull origin master合并new-feature#git merge new-feature更新至远程# git push origin master则master中也合并了new-feature 的代码
