昕昕尿裤子后...
白天，姥姥带着昕昕去枫丹玩滑梯
昕昕特别喜欢玩那个滑梯
每次去都是高高兴兴的玩一遍又一遍
今天，据说又是玩的很开心
于是，就把撒尿的事给忘了
等憋的不行了，才想着去撒尿
结果，还没来得及把裤子扒开
就已经尿了出来
把裤子彻底的给尿湿了
其实，昕昕已经好久都没尿过裤子了
没想到，尿裤子后
他对姥姥说了一句挺雷人的话：
姥姥可不要告诉别人宝宝尿裤子了
晕啊...
昕昕才2岁2个月，就知道尿裤子羞了...
呵呵

Windows下的“任务计划”
相对于Linux上的crontab
Windows上就是“任务计划”了
我们一般都是在控制面板里增加任务计划
其实，也可以通过命令工具来管理任务计划的
增加一个任务计划，每5个小时执行del.bat
del.bat是删除某个文件夹下的所有log文件
如果直接执行.bat文件的话，在执行时是会弹出一个命令窗口的
我们可以再.bat的目录下创建一个.vbe文件
ws.run "del.bat /start",0
然后修改我们的任务计划
这样就可以了

昕昕趣事几则（1）
1.只要每次看到我开了电脑，还没等我输入密码进入系统
它就已经跑了过去，抢占了凳子、键盘和鼠标
就开始煞有其事的用手敲打键盘，按着鼠标
我就把手伸过去，想输入密码，进入系统
他就一下子推开我的手，又冒出这样一句话：
爸爸让开，宝宝正干活呢....
2.昕昕特别喜欢和别人玩“藏猫”的游戏
但他每次都只会藏在一个地方，就是小屋的门后边
虽然对他说过好多次换个地方，但他就一直藏那边
这倒还罢了，我们找他时，经常就装着到处找他
"昕昕藏哪了呢？阳台上呢？没有，床上呢？没有"
就这么假装到处找他，今天正装着找他呢
没提防，这小子突然从门后冒出来一句：
到门后边找找宝宝吧...
真晕...
3.早上不到5点多钟，这小子就醒了，开始说“喝粉粉”了
于是，迷迷糊糊的爬了起来给他冲完了
一气喝完后，就来了句“宝宝不睡了”
就下床，说了句“ByeBye”，关上门，去另一个屋了
等8点多种，这小子推开门怕上床
用手开始推我的头要我起床，我没动静
他就继续推，嘴里还说着什么“爸爸起来...”，没听太清楚
然后，他就又下床，不一会儿，回来了
手里拿着我的剃须刀，自己打开，然后放到我脸上
这时，才明白过来，人家刚才说的是“爸爸起来刮胡子了”（这是我每天起床的第一件事）
今天，这把我这个当爸爸爸的服务的可真周到....
Git的目录结构
./git/config是当前仓库的配置信息
./git/HEAD存放着当前分支（branch）的名字。
./git/refs/heads/存放了所有分支（branch）的最后一次提交的对象的引用。
./git/hooks里存放了一堆的hook脚本，如果要启用某个hook，则只需把对应名字后面的.sample给去掉即可
Git Objects
Git中有4种类型的Object
object是根据内容的SHA1值来命名的
也即长度为40的16进制数
Every object consists of three things - a type, a size and content. The size is simply the size of the contents, the contents depend on what type of object it is
使用以下命令，可以查看object的类型
1.commit object:
对应于我们每次的commit，对应git log里的每个commit
下面命令可用来查看commit对象的内容
显示结果如下：
tree 9dba3538ed085b2758cfa56190fee72d0da5fc49
parent e9cbbda4daf535e8b58e2d34957cadf7a3baab61
author test 1254019797 +0800
committer test 1254019797 +0800
parent e9cbbda4daf535e8b58e2d34957cadf7a3baab61
author test
committer test
commit对象包含其父对象的指针parent和指向tree对象的指针
2.tree object:
它一般是目录和子目录的内容，指向一堆blob对象和其他的tree目录。
每次commit时，Git 会先计算每一个子目录的校验和，然后生成一个tree对象，tree代表了这次commit时整个项目目录的快照
可以使用命令来显示tree对象的内容
3.blob object:
它实际上就是一个文件的数据内容
可以使用命令来显示blob的内容
或者，使用show命令
4.tag object:
对应于一个tag
objects之间的关系如下图：
office文档转换为html的实现方案
1. doc/docx
(1)调用com组件，这种方式实现起来比较简单，使用jacob即可，见 http://danadler.com/jacob/，但其有以下局限性：
*必须得运行在windows机器上
*目前office提供的script功能有限，当word文档错误时，会弹出一些窗口
*当多线程调用时，占用cpu很高，机器很容易down掉 最早解析word时，是采用的com，上线后没多久，因为不稳定，不可靠，就下线了
(2)poi，见http://poi.apache.org，现在它对word的支持还很弱，用它来解析出txt还是可以的，转换为html就很难了
(3)openoffice
openoffice需要jre才能正常安装，所以首先需要安装jre，然后配置java的环境变量
从http://zh.openoffice.org/new/zh_cn/downloads.html这里下载最新的rpm包
安装后，其服务默认是单进程但线程运行的，如果使用其默认的启动参数
即使你启动多个进程，每个对应的port不同，最后soffice也只起了一个进程，但这个进程监听了多个端口，这样，其实还是单进程运行的 后来，参考了oooserver，见http://www.re.be/oooserver/index.xhtml，看了其源码后，发现启动时多加个参数，还是可以启动多个进程实例的
多加了一个UserInstallation参数，该参数指定了安装目录，如果不加该参数，openoffice在启动时会检查是否已经存在了默认目录下对应的soffice的进程，如果存在，可能就不再启动新的实例了 多个进程起来后，需要自己实现一个process pool，控制协调各个进程，保证其同一个时刻只服务一个文档转换 目前，在服务器上起了5个进程，我们会根据日志情况，再来调整进程数目
2.xls
之前也是只使用com组件，出现的问题同上
现在，采用了poi + com来实现，先是用poi来解析，如果发现里面有嵌入组件、图片、图标等内容，则转交给com来出来，否则就由poi自己来解析
使用poi的关键在于，自己要实现单元格合并的处理逻辑
3.pdf
采用了xpdf工具，见http://www.foolabs.com/xpdf/，其能有效的处理中文，但现在只能parser出txt来
Git merge的三种模式
在使用git merge时，可能是以下三种模式中的某一种
1.Fast forward
当待合并的2个branch最近的commit是线性关系时
或者说，某个branch自上次更新后没有commit信息时
git则直接移动指针即可，并没有真正的merge操作，也没有对应的merge commit信息
如下图，合并master和hotfix分支，既是fast-forward模式
2.Merge made by recursive
当要合并的2个branch的最近的commit对应的直接祖先不同时
git就无法通过简单的移动指针来进行合并
只能以2个branch的最新commit和他们的共同祖先进行一次merge
并对应有一个merge commit信息
如下图，合并master和iss53分支：
3.Conflict
当2个branch都修改了同一个文件的同一部分时
这时，就会发生冲突，git的自动合并就会失败
这时，使用git status会看到
test.html: needs merge
需要手工合并冲突后，git add一下，表明冲突修改完了
然后，再git commit即可
Git之点点滴滴
在应用Git过程中的一些点滴小东西
记录下来，以备查看：
1. git config
配置git的参数变量，它可以带以下2个参数：
--system，针对系统的所有用户的，对应的配置文件在/etc/gitconfig
--global，针对系统当前用户的，对应的配置文件在~/.gitconfig
不带参数，针对当前git仓库的，对应的配置文件在.git/config
如果在个人pc上使用git，加上参数--global即可
如果在公共服务器上使用git，则一定不要带那2个参数
2. git push origin b3
默认会把本地的b3分支提交到远程的b3分支上，如果本地分支和远程分支名不同，一定要这样
折叠复制代码
- git push origin b3:b1
也即把本地的b3分支提交到远程的b1分支上
3. 查看某个版本修改的文件信息
折叠复制代码
- git log e99a6a --name-status -n 1
4. 找出哪些commit修改了某个文件
折叠复制代码
- git log --pretty=oneline -- 'web/webapp/postcard/template05.pn
5. 查看某个版本某个文件的内容
折叠复制代码
- git show dfb02:maillib/basemaildir.py
Git rebase的应用
Git的官方手册上，这么解释rebase的
Forward-port local commits to the updated upstream head
很简单的一句话，确实很让人迷惑...
简单的说，就是把在一个分支里提交的改变应用在另一个分支里
从这层意义上讲，git rebase是类似git merge的
它们最终的结果是一致的，都是合并2个分支的内容
但是，git rebase合并后的commit信息是一个线性的，没有分叉，看起来比较整洁
以下，引用progit中的几个图示
例如：我们原始有2个分支：master和expriment
这2个分支都有自己的一个commit信息
如果，我们使用git merge来合并
那么，合并后的大概是这样
如果，我们使用git rebase来操作
git checkout master
git rebase expriment
那么，结果会是这样
对于远程分支，我们可以在push之前
git checkout master
git fetch
git rebase origin/master
它的操作过程是
git rebase origin/master will take the local commits (that are reachable from the master head, but not from origin/master), remove them from the commit tree, and re-apply them on top of origin/master
看一下这个图示，就大概明白了
除了合并代码外，rebase还可以修正本地的commmit信息
可以参考
Git往远程push前修改commit信息
使用rebase的一个重要原则
永远不要衍合那些已经push到remote server上的commit
