Tip
除了用 clang-format 格式化代码，也可以用 git-clang-format 格式化 commit, 如果只是想查看格式化前后对比，可以通过加参数 ‘‘-diff’’ 实现。
➜ ~ git-clang-format --help
usage: git clang-format [OPTIONS] [<commit>] [<commit>|--staged] [--] [<file>...]
If zero or one commits are given, run clang-format on all lines that differ
between the working directory and <commit>, which defaults to HEAD. Changes are
only applied to the working directory, or in the stage/index.
Examples:
To format staged changes, i.e everything that's been `git add`ed:
git clang-format
To also format everything touched in the most recent commit:
git clang-format HEAD~1
If you're on a branch off main, to format everything touched on your branch:
git clang-format main
If two commits are given (requires --diff), run clang-format on all lines in the
second <commit> that differ from the first <commit>.
The following git-config settings set the default of the corresponding option:
clangFormat.binary
clangFormat.commit
clangFormat.extensions
clangFormat.style
positional arguments:
<commit> revision from which to compute the diff
<file>... if specified, only consider differences in these files
options:
-h, --help show this help message and exit
--binary BINARY path to clang-format
--commit COMMIT default commit to use if none is specified
--diff print a diff instead of applying the changes
--diffstat print a diffstat instead of applying the changes
--extensions EXTENSIONS
comma-separated list of file extensions to format,
excluding the period and case-insensitive
-f, --force allow changes to unstaged files
-p, --patch select hunks interactively
-q, --quiet print less information
--staged, --cached format lines in the stage instead of the working dir
--style STYLE passed to clang-format
-v, --verbose print extra information
--diff_from_common_commit
diff from the last common commit for commits in
separate branches rather than the exact point of the
commits关于黑天鹅
塔勒布在《黑天鹅》中说道:
我们的世界是由极端、未知和非常不可能发生的（以我们现有的知识而言非常不可能发生的）事物所主导的，而我们却一直把时间花在讨论琐碎的事情上，只关注已知和重复发生的事物
一只鸡每天都等着准时的喂养，直到圣诞前天，被做成食物，未来是混沌的，难以预测，我们潜意识也要准备黑天鹅的到来，无论是正向黑天鹅，还是黑天鹅。平常的日子里好好吃饭、好好锻炼、好好看书、好好工作，直到黑天鹅事件发生，抓住机会，趁势而发。
关于街头智慧
接触的人越多，发现读了书的、学历高的貌似是一个模子里面刻出来的，单线思维，患得患失，也许就是绩优主义的后遗症，像是《优秀的绵羊》描述的那样：
这套精英教育体系培养出来的学生大都聪明，有天分，斗志昂扬，但同时又充满焦虑、胆小怕事，对未来一片茫然，极度缺乏目标感：他们被包裹在一个巨大的特权泡泡里，所有人都在老实巴交地向着同一个方向前进。他们非常擅于解决手头的问题，却不知道为什么要解决这些问题。
反而那些早早出来工作，在一些传统行业比如餐饮摸爬滚打的人，活得通透。
关于自由的追求：
1.财务自由
2.健康自由
3.时间自由
4.关系自由
