ipch文件夹是Intelli Sense（好像是预编译头文件之类的）这个东西产生的缓存文件，占用空间很大！！！每编译一次文件就会产生ipch里对应的一个文件夹。我看了我的ipch文件夹产生了121个对应的文件夹，总共产生了6G多。。。惊人啊！
在VSCode找到设置→扩展→C/C++→Intelli Sense Cache Path，如上图。1处写明了vscode默认Intelli Sense缓存文件路径是在C盘的，2处可以更改为你要保存缓存文件的位置。据我所知，这些缓存文件删了也不影响的之前的文件的，所以可以随时删~只是每次编译又会重新产生，所以还是把缓存路径改为别的盘吧
In ~/.bashrc, add:
1 | export all_proxy="socks5://127.0.0.1:<port>" |
where <port> is your VPN’s sock port (default V2ray: 20170)
Found this when I was in 10th grade been using it since:
For sin(a+b)= sin(a)cos(b)+cos(a)sin(b)
Say out loud: “sine cosine cosine sine”
For cos(a+b)= cos(a)cos(b)-sin(a)sin(b)
Say out loud: “cosine cosine SIGN sine sine”
Notice the word “SIGN”. The word SIGN is there to remind you that the SIGN of the rightmost term has the opposite SIGN of the input to the cosine on the left hand side of the equation (if its a+b, then subtract. if its a-b, then add).
For some reasons(see the blog yourself), I wanted to start my personal blog. The requirements of the blogger platform are: easy maintenance(including deployment and easy fee), and allowing custom configurations(themes, domain, font, etc.). In order to meet these requirements as well as to be cool, I finally chose Hexo, a .js based static website generator.

To mount a device with certain rights, you can use the -o Option directive while mounting the device.
clean cache(public folder): hexo clean
generate public files(static files): hexo g
preview the website: hexo s (--debug)
