井。改邑不改井，無喪無得，往來井井。汔至亦未繘井，羸其瓶，凶。——井。你可以改變村莊但唔可以改變井。佢既唔減少亦唔增加。佢哋嚟去並從井抽水。如果繩去唔到水，或罐破咗，凶。

Information Theorem
克勞德·香農《通信嘅數學理論》
克勞德·香農（Claude Shannon） (1948)
1948 年 7 月，克勞德·香農喺《貝爾系統技術雜誌》發表《通信嘅數學理論》，創造咗信息理論並定義數碼時代。香農之前，『信息』係含糊——新聞、知識、意義。香農之後，信息變成可以用位元（bits）衡量。佢嘅關鍵洞見：將訊息同意義分開。信息唔係講緊乜而係可以講乜。訊息攜帶嘅信息同佢嘅驚喜成正比——完全確定性唔攜帶任何。香農用熵量化呢個：H = -Σ p(x)log₂p(x)，測量自由度、可能狀態、可以係乜嘅空間。從呢個基礎嚟咗壓縮算法、糾錯、通道容量、位元本身。卦四十八係井（The Well）——水在木上，社區日日抽嘅無盡源頭而唔枯竭。香農創造咗數碼世界日日抽嘅井：數學證明你可以透過唔完美通道完美溝通，透過加啱冗餘。七十七年後，每個協議設計師都返去同一個源頭。井唔會乾。
Historical Context
- Period
- 周朝
- Oracle Bone Etymology
- 水（☵）在上，巽（☴）在下——水從井抽上。
- Traditional Use
- 井係村莊嘅無盡源頭。朝代改變，村莊搬，但井保留。佢滋養每個從佢抽水嘅人而唔枯竭。古典教導：維護井，保持佢清潔，佢就無限服務。

Practical Guidance
工程組織唔可以不斷重新定義基礎。團隊改變、產品演變、堆疊轉變——但你需要所有人依賴嘅穩定抽象。井原則：一次建啱源頭，容許所有人無限抽取。
香農嘅信息理論係柏拉圖理想。七十五年後，每個壓縮編解碼器、糾錯方案、通道容量計算都從嗰啲 1948 年方程抽取。香農數學無 bug。井建得啱。
喺你代碼庫，井係你嘅基礎庫。唔會每季瘋狂嘅核心抽象。當設計呢啲層時，你挖緊你團隊會日日抽取嘅井。
文警告：如果繩去唔到水，凶。太難訪問嘅美麗抽象會失敗。香農令定理可用——優雅方程、清晰記號、實際例子。界面同深度一樣重要。
如果罐破咗，凶。當基礎層失敗（破碎錯誤處理、違反 API 合約、內存洩漏），所有依賴佢哋嘅人都失敗。完整性唔係可選。
你可以改變村莊但唔可以改變井。產品轉向、團隊重組、公司被收購。但核心協議、基本數據結構、基本算法——呢啲保持穩定。香農 1948 年出版；2025 年嘅電訊工程師仍然參考同樣嘅定理。
人們錯過嘅：井唔係靜態，係維護。香農嘅框架係穩定，但實現改進（LDPC 碼、turbo 碼、現代壓縮——全部喺香農界限內）。你嘅核心庫應該穩定，唔係凍結。Bug 修復同更好界面係有效。基本抽象唔應該瘋狂。
識別你系統入面應該係井嘅嘢。乜抽象夠基本到可以保持穩定，同時其他所有嘢改變？你嘅香農熵公式係乜——所有人會喺未來十年參考嘅核心洞見？
用香農嘅小心建呢層。令佢正確、可訪問、無盡。容許你團隊日日從佢抽取而唔使擔心。井服務因為佢可靠喺度。
