@mcwangcn 我没有办法设置我的语言。它认为我说英语，可能是因为错误的浏览器环境。
另外，移动端样式似乎还需要进一步优化，现在有些地方 overflow 了。

世界杯快到了，抽空做了个免费聊天室 babel.town 让大家有个地方聊聊球。
这个聊天室的特点是自动翻译，也就是你用什么语言聊天，其他人的发言就会自动以你的语言显示，从而真正实现了全球用户的无障碍交流。
如果不需要翻译也没问题，点页面上方的翻译按钮切换即可。

Elon Musk memorized the entire Encyclopedia Britannica as a child.
Not parts of it. The entire thing. His brother Kimbal said he would read for ten hours a day. Not children's books. Encyclopedias. Physics textbooks. Science fiction. Anything he could find. By the time other kids were learning long division, Elon had read more than most adults read in a lifetime.
His mother Maye said the other children called him the encyclopedia because he would recite facts nobody asked for. At dinner. At school. In the middle of conversations that had nothing to do with what he was reciting. He couldn't stop. The information came in and it needed to come out.
This is the part of the Musk origin story that everyone skips because it's not dramatic.
Nobody makes a movie about a child reading. Nobody writes an article about ten thousand hours in a library. But that library is the foundation under every rocket, every factory, every company. The man who argues with NASA engineers about propulsion chemistry learned that chemistry from a book he read at age eleven.
Most people who want to be like Musk study his companies. His management style. His tweets. They skip the reading because reading doesn't look good on camera.
The secret was never the rockets. The secret was the ten year old who read the entire encyclopedia and never stopped.

Go is stable, compiles fast, runs fast enough, and any code I write can be cross-compiled to any OS, even decades later.
Also, my laptop's hard drive is dying, so using Rust's LSP slows down to a crawl.
I want to finish this thing quickly without wasting time.
So, Go seems ok.

@oxcrowx Why did you pick Go over Rust for your compiler?

NaN boxing
IEEE 754 says a 64-bit float is NaN when all 11 exponent bits are 1
but it leaves 52 mantissa bits undefined
and modern 64-bit pointers only use 47 bits
LuaJIT, JavaScriptCore, and SpiderMonkey all exploit this
every value in the language nil, true, false, integers, strings, pointers is stored inside a single 64-bit double
one 8-byte field carries any type
if the double is a real number it is just a normal float
if the upper 13 bits are all 1 it is a NaN
and the remaining bits carry the type tag and the payload
this is the actual layout from LuaJIT's lj_obj.h

听姚顺宇的访谈说到：
“给面试者24小时来实现一个强化学习的训练，一方面可以看出这个面试者对这份工作的需求/努力程度（愿不愿意熬夜），二方面可以体现面试者的综合能力。同时在结束coding讨论时可以技术细节，看是不是只用AI不了解技术细节哦”
非常同意这个面试方式
Yifeng "Evan" Wang@ewind_dev
非常同意，你如果聊过几百个人，会发现多数人都是循规蹈矩中规中矩的，现在兴起的原生外挂 claude 的小天才，对传统编码老实人那真是降维打击…… 不仅八股知识点和手写代码的问题废了，我原本喜欢的那种开放挖掘人选亮点的风格也废了，上 claude 随便许愿就行啊。 那工程面试 eval 该评测什么呢？

国内老是搞违禁词，都没办法正常交流了，然后就衍生出各种各样的黑话代替。我现在都没办法直视自求多福、福如东海这样的成语了😅

逼就叫逼，为什么要改成叫福？ 球球你们了，不要一直给生殖器取新名字，已经够多名字了。
