大端序，小端序
Examples with the number 0x12345678 (i.e., 305 419 896 in decimal):
little-endian: 0x78 0x56 0x34 0x12
big-endian: 0x12 0x34 0x56 0x78
mixed-endian (historic and very rare): 0x34 0x12 0x78 0x56

zig 这门语言似乎是和 rust 产生竞争，抢占 c 语言的市场
The primary goal of Zig is to be a better solution to the sorts of tasks that are currently solved with C. A primary concern in that respect is readability; Zig attempts to use existing concepts and syntax wherever possible, avoiding the addition of different syntax for similar concepts. Further, it is designed for “robustness, optimality and maintainability”, including a variety of features to improve safety, optimization, and testing.

没想到 win7 的发布，距离现在已经 16 年了，我目前还在使用的成功的系统。
Windows 7 was released to manufacturing on July 22, 2009. It was made available to the public on October 22, 2009.
The Windows 7 end-of-life was on January 14, 2020. This was when Microsoft discontinued technical support and quit supplying Windows 7 users with software updates and security fixes through Windows Update.

最近看的书：《人性的迷雾》，这页话应该是最恐怖的一段了，能解开世间很多差异，我们本能的以为世界是我们理解的样子，我们的理解受限
于我们的认知，我们的认知受限于我们的大脑的物理条件。
长时间的环境甚至会影响我们的大脑结构。

一群程序员在聚餐，有点闷，有人学唐伯虎对穿肠对对子，上联曰：产品找开发开发产品。苦对不得，问 ai ，ai 答：下属求老板老板下属，喷饭。
求助各票圈大佬下联。

昨天和男友在外面逛，当经过美甲店的时候，他说道：“真不懂你们女生，为什么那么喜欢做这些美甲。这又不是去做按摩，做的过程难道会很舒服吗？”
这么一说，激起了我很多想法，因为我也早就对这件事情有所感触。
首先，关于去做美甲这个事情，我并没有去体验过，所以也很难说太多。
不过，我也曾跟风买过那些类似美甲一样的穿戴甲，戴上后确实感觉手指变修长了，蛮好看的，但没半个小时我就受不了了：
指甲这么长，感觉干啥都不方便，刷手机、敲键盘、做菜、戴隐形眼镜，都要小心翼翼的；
而且觉得要是不小心勾到指甲末端，会不会把整片指甲直接掀了起来？想想都觉得很可怕。

The inset CSS property is a shorthand that corresponds to the top, right, bottom, and/or left properties.

乱语：写了 10 多年的 css，才发现 inset 是 left top 的简写。

javascript 里面的很多操作就是 Monoid
The term Monoid comes from category theory. It describes a set of elements which has 3 special properties when combined with a particular operation, often named concat:
The operation must combine two values of the set into a third value of the same set. If a and b are part of the set, then concat(a, b) must also be part of the set. In category theory, this is called a magma.
The operation must be associative: concat(x, concat(y, z)) must be the same as concat(concat(x, y), z) where x, y, and z are any value in the set. No matter how you group the operation, the result should be the same, as long as the order is respected.
The set must possess a neutral element in regard to the operation. If that neutral element is combined with any other value, it should not change it. concat(element, neutral) == concat(neutral, element) == element

Compose 感覺起來就像在飼養 function。你就是 function 的飼養員，選擇兩個有你喜歡特色的 function 並將它們組合，產生一個新的 function。

If you are writing code and it is getting a little too complex to fit everything into one function, what can you do to make it more elegant? One solution is to create multiple functions to separate the logic, but is there a more elegant way to do this?
One interesting proposal in Stage 1 on the TC39 GitHub is related to the topic I will be discussing in this post. Although it is still incomplete, it is a good proposal that is worth reading.
In this post, I will introduce a technique used in functional programming called “Pipe” or “Pipeline.”

给候选人做的题，应该好理解，如果讲半天题目，对方都不理解，我都怀疑是不是我的表达能力不行。题目足够简单，我讲解题目也省事，对方不理解或者不能做出来，则淘汰就好，我心里也没有负担。
