Add Image

方法略繁复
把图像复制到/……/octopress/source/images目录下。（也可再建立子文件夹）
把图片上传到github repository托管

git add .           # don't forget the "."
git commit -m 'your message'
git push origin source

进入github抓取图片链接地址（先打开图片，然后鼠标右击图片，在新标签页中打开图片=或者=查看图片）
示例地址：
https://raw.githubusercontent.com/qiuhaidong/qiuhaidong.github.com/source/source/images/123.png
使用 ![描述](图片链接地址) 插入图像
示例：
image test

GoAgent

2016-01-09 goagent的github仓库已经全部删除，it’s gone.

新网址
压缩包下载地址
简易教程

部署

  1. 申请 Google Appengine 并创建 appid。
  2. 下载 goagent
  3. 修改 local\proxy.ini 中的 [gae] 下的 appid = 你的appid(多appid请用|隔开)
  4. 运行 uploader.bat 或 uploader.py 开始上传, 成功后即可使用了。

使用

  • Windows 用户推荐使用 goagent.exe 托盘图标设置 IE 代理(对其它浏览器也有效)。
  • Chrome/Opera 请安装 SwitchyOmega 插件(下载到本地然后拖放文件到扩展设置)，导入 SwitchyOptions.bak
  • Firefox 请安装 FoxyProxy ，Firefox需要导入证书，方法请见 FAQ
  • 出现连接不上的情况可以尝试使用 gscan 或 GoGo Tester 测速。

停止rake preview 任务，用ctrl+c，别用ctrl+z，可以避免这个问题

在执行命令

解决方法：
执行：

sudo netstat -tulpn |grep 4000

如果提示：

1

sudo: netstat：找不到命令

运行：

1

netstat -tulpn |grep 4000

然后：

1
2

4

dong@Ubuntu:~/octopress$ netstat -tulpn |grep 4000
Command 'netstat' not found, but can be installed with:
sudo apt install net-tools
dong@Ubuntu:~/octopress$ sudo apt install net-tools

再运行：

1

sudo netstat -tulpn |grep 4000

得到：

dong@Ubuntu:~/octopress$ sudo netstat -tulpn | grep 4000

阿甘的奔跑

想起阿甘。
阿甘有点傻，一点点傻。
他经历了战友布巴的离世，丹中尉的悲怨起伏，母亲的离世，以及贯穿他整个生命的珍妮的美好而又若即若离触不可及。
阿甘不孤单。
童年时母亲和珍妮陪他。当兵时布巴陪他。在海上捕虾时丹中尉陪他。
阿甘只是孤独。
没有人走进阿甘的心里。
没有人想走进阿甘的心里。
或者说：
珍妮没有走进阿甘心里。
珍妮不想走进阿甘心里。
当珍妮再次离开，所有孤独，清晰浮现。
阿甘开始奔跑。
跑到城边。
跑遍县城。
横越阿拉巴马州。
跑到一个海角。
跑到另一个海角。
横越美国。
在湖边奔跑。
在麦田旁奔跑。
在河流石桥上奔跑。
在栅栏边奔跑。
在牧场旁奔跑。
在秋天黄叶林中奔跑。
在沙漠奔跑。
三年，两个半月。
后来，珍妮问起，阿甘告诉她：
战场雨停后的星空。
海湾的日落。
雪山旁湖面的倒影。
沙漠的日出。
那些属于阿甘的，一个人的一些瞬间。

生活 经历 迷宫

生活像是一座特殊的迷宫。

它是立体的，一层一层的，无尽的。

它有不可改变的部分，非常难以改变的部分，容易改变的部分。有了足够的经历积累后，会出现一个楼梯，走上去，看下来，之前走过的那一层迷宫，一目了然。
