一些实用的小技巧。比较杂。
调试程序
- 二分调试法
- 使用宏
#define debug fprintf(stderr,"Passed [%s] in line %d\n",__FUNCTION__,__LINE__)
网易云歌曲下载
注：在网易云网页版操作。
进入一个单曲的页面时，网址上会有这首歌的ID，像这样：
https://music.163.com/#/song?id=XXX。这里的id=XXX即是。
将以下网址中的XXX改为这首歌的ID，访问之，即可下载（可能质量不佳）。
http://music.163.com/song/media/outer/url?id=XXX.mp3
博客备份
为了保证我们写的文章不丢失、快速迁移博客，都需要备份我们的 blog。
博客根目录，执行
git init创建 git 仓库。在 github 创建仓库并和本地仓库建立联系。
在
~/.bashrc文件中添加以下内容：alias hs='hexo clean && hexo g && hexo s' alias hd='hexo clean && hexo g && hexo d && git add . && git commit -m "update" && git push -f'
这样，执行hs即可启动本地服务；执行 hd 进行部署博客时，就一同将博客进行备份了。
把文件藏到图片里
很多的时候，我们需要把某些文件藏到一张图片的里面，这样方便传播而且一般人根本不知道其中有文件。我们把图片放在网上，别人把原图下载下来然后用解压软件打开，就可以看到里面的文件了。示例图片：
)
准备文件及图片
你需准备一个文件，一个图片（Normal-picture.jpg）。
将文件压缩为.rar或.zip格式的图片（demo.rar）。
运行命令
在当前目录下打开cmd.exe，运行以下命令：
copy/b Normal-picture.jpg+demo.rar A-Normal-picture.jpg
得到图片
这时我们可以看到在当前目录下面生成了一张名为A-Normal-picture.jpg的图片，这就说明我们的文件就已经藏到里面去了。
恢复文件
将A-Normal-picture.jpg的后缀改为 .rar ，即得到一个名为A-Normal-picture.rar的压缩包。解压即可。你可以从示例图片中得到“扫雷.exe”。
判断 .jpg 图片类型
文件中前 8 个字节是 FF D8 FF E1 的为 CMYK 模式，而 FF D8 FF E0 的为 RGB 模式。
凹凸
凹和凸都是 划的汉字。
遵循汉字的书写方式：从上到下；从左到右；先中间外边（半包围结构）；先外面后里面，最后封口（全包围结构）。

你，学会了吗（）
扫雷作弊码
在扫雷界面依次按键盘键：X，Y，Z，Z，Y，shift。
这样，会在扫雷界面或屏幕界面左上角出现一个像素的点，当鼠标在雷上时，点为黑色；否则为白色。建议换黑色壁纸，这样看得出来。
