贝佐斯对我影响最大的两个顶级认知：

1. 你的压力来自于想到到做不到，想到但未采取行动。拖得越久，压力越大。只要你开始行动，压力就会被释放。

2. 不应该在计划上投入太多时间。但你要非常明确你将前往的目的地。然后马上启程，向目的地前进。记住，无论你如何精密计划，大概率都不会奏效。因为一开始，你不可能清楚通往目的地的路径。路径是走出来的，不是规划出来的。

Claude背后的故事值得被记住。

[Tech with Mak @techNmak]

In 1948, a 32-year-old at Bell Labs published a paper nobody fully understood.

Engineers found it too mathematical. Mathematicians found it too engineering-focused. One prominent mathematician reviewed it negatively.

That paper - "A Mathematical Theory of Communication", became the founding document of the digital age.

The man was Claude Shannon. Father of Information Theory.

At 21, he wrote the most important master's thesis of the 20th century.

Working at MIT on an early mechanical computer, Shannon noticed its relay switches had exactly two states - open or closed. He had just taken a philosophy course introducing Boolean algebra, which also operated on two values: true and false.

Nobody had ever connected these two things.

His 1937 thesis proved that Boolean algebra and electrical circuits are mathematically identical, and that any logical operation could be built from simple switches.

Howard Gardner called it "possibly the most important, and also the most famous, master's thesis of the century."

Every digital computer ever built traces back to this insight.

At 29, he proved that perfect encryption exists.

During WWII, Shannon worked on classified cryptography at Bell Labs. His work contributed to SIGSALY, the secure voice system used for confidential communications between Roosevelt and Churchill.

In a classified 1945 memorandum, he mathematically proved the one-time pad provides perfect secrecy, unbreakable not just computationally, but provably, permanently, against an adversary with infinite power.

When declassified in 1949, it transformed cryptography from an art into a science. It laid the foundations for DES, AES, and every modern encryption standard.

At 32, he defined what information is.

His 1948 paper introduced one equation:
H = −Σ p(x) log p(x)

Shannon entropy. The average uncertainty in a probability distribution. The minimum bits required to encode a message.

Three things followed:

> He defined the bit - the fundamental unit of all information. His colleague John Tukey coined the name.

> He proved the channel capacity theorem, every communication channel has a maximum rate of reliable transmission. You can approach it. You can never exceed it.

> He unified telegraph, telephone, and radio into a single mathematical framework for the first time.

Robert Lucky of Bell Labs called it the greatest work "in the annals of technological thought."

Where his equation lives in AI today:

Cross-entropy loss - the function training every classifier and language model, is derived directly from H. Decision tree splits use information gain, which is H applied to data. Perplexity, the standard LLM evaluation metric, is an exponentiation of cross-entropy.

Every time a neural network trains, Shannon's formula runs inside it.

He also built the first AI learning device.

In 1950, Shannon built Theseus, a mechanical mouse that navigated a maze through trial and error, learned the correct path, and repeated it perfectly. Mazin Gilbert of Bell Labs said: "Theseus inspired the whole field of AI."

That same year he published the first paper on programming a computer to play chess. He co-organized the 1956 Dartmouth Workshop, the founding event of AI as a field.

The man:
He rode a unicycle through Bell Labs hallways while juggling. He built a flame-throwing trumpet, a rocket-powered Frisbee, and Styrofoam shoes to walk on the lake behind his house.

He called his home Entropy House.

When asked what motivated him: "I was motivated by curiosity. Never by the desire for financial gain. I just wondered how things were put together."

In 1985, he appeared unexpectedly at a conference in Brighton. The crowd mobbed him for autographs. Persuaded to speak at the banquet, he talked briefly, then pulled three balls from his pockets and juggled instead.

One engineer said: "It was as if Newton had showed up at a physics conference."

He died in 2001 after a decade with Alzheimer's, the cruel irony of information slowly leaving the mind of the man who defined what information was.

Claude, the AI model, is named after Claude Shannon, the mathematician who laid the foundation for the digital world we rely on today.

走暗路，耕瘦田，进窄门。

结硬寨，打呆仗。

广积粮，高筑墙。

[鱼仔 @ExpLang_Cn]

很多人把 “走暗路、耕瘦田、进窄门”，理解为一种逆袭捷径：哪里冷门就去哪里，什么事情困难就坚持什么。

其实不是。

对资源有限的普通人来说，这九个字真正提醒我们的，是不要在别人占尽优势的地方正面竞争。

热门赛道看上去机会最多，但资源、信息和人脉也最集中。

别人可以反复试错，你可能一次失误就要付出很大代价；
别人有人指路，你却需要自己摸索。
大家虽然遵守同一套规则，手里的筹码却完全不同。

所以，普通人需要寻找的并不是更苦的路，而是更适合自己的竞争方式。

所谓“走暗路”，不是故意隐藏自己，而是暂时避开过度拥挤的方向，寻找尚未被充分关注的需求。

所谓“耕瘦田”，不是把贫瘠当成浪漫，而是在资源有限的情况下，从小机会开始积累技能、作品和信任。

所谓“进窄门”，也不是越难越正确，而是选择那些有门槛、能积累、短期内不容易被复制的事情。

但必须注意：冷门不等于机会，困难也不等于价值。

判断一条路值不值得走，至少看三点：
有没有人真正需要；
你能不能建立优势；
长期投入能否形成积累。

如果没有需求，再努力也只是自我感动；
如果无法积累，做得再久也可能一直从零开始；

如果没有任何优势，所谓“坚持”很可能只是延迟止损。
因此，这九个字不是劝普通人认命，更不是歌颂吃苦。
它真正的价值，是提醒我们看清自己的筹码：

不要拿有限的资源，去打一场别人占尽优势的战争；
要在能够积累的地方，慢慢扩大自己的选择权。

真正的逆袭，从来不是专门挑苦路走，而是知道哪些竞争没必要参加，哪些机会值得长期投入。

暗路不是捷径，瘦田也不是命运。
能把有限条件变成长期优势，才是普通人真正的破局。

@dtzy_88 听起来有些道理。有没有可能是为了吸引更多的用户，有更大的竞争力或者要推出新模型了
