🌗 Whistler：在 Common Lisp REPL 中進行即時 eBPF 程式設計
➤ 告別冗長編譯，在 Lisp REPL 中體驗極致的系統探測
✤ https://atgreen.github.io/repl-yell/posts/whistler/
Anthony Green 推出的 Whistler 是一套革命性的工具，讓開發者能直接在 Common Lisp 環境中撰寫並執行 eBPF 程式。Whistler 打破了傳統必須依賴 C 語言、Clang/LLVM 工具鏈及繁瑣編譯流程的限制，將 eBPF 編譯器直接整合進 Lisp 的 REPL（讀取-求值-輸出循環）中。透過在巨集擴展（macroexpansion）階段完成編譯，Whistler 能即時將代碼轉換為 eBPF 位元組碼並載入核心。這種開發模式不僅實現了核心層與使用者空間的無縫銜接，還支援從執行中的核心直接導入結構定義，極大地縮短了系統監控與安全程式的開發週期。
+ 這種設計簡直天才。對於經常需要調整監控探針的系統工程師來說，能直

🌘 Common Lisp 開發工具指南
➤ 從零開始構建你的 Lisp 互動式開發環境
✤ https://www.creativetension.co/posts/common-lisp-development-tooling
對於初學者而言，Common Lisp 的開發環境往往因層級繁多且缺乏直觀的對應機制而顯得難以入門。本文旨在建立一套清晰的「開發地圖」，將複雜的 Lisp 工具鏈拆解為六個核心層級，從底層的編譯器到頂層的編輯器整合，逐一剖析各層的功能與選型。作者透過此架構幫助開發者建立除錯的心智模型，明確區分各層級的職責，進而讓新手能從挫折中解脫，建立起高效的互動式開發流程。
+ 這篇文章真是雪中送炭。以前總是搞不懂 ASDF 和 Quicklisp 的差別，現在看這個架構圖一目瞭然，終於知道錯誤該去哪一層找原因了。
+ 很棒的入門指南。雖然 Lisp 的學習曲線陡峭，但將其視為「互動式執行環境」而非單純的編譯過程，確實是掌握這門語言的關鍵。
