從 2014 開始，在 logdown 寫技術部落格，首篇探討 Java 8 的新特性 (未收於本書)，接連寫了幾篇，後來主題慢慢轉向軟體架構與設計。

開始寫技術部落格的契機，是看到 Teddy 學長的兩本書出版：《例外處理設計的逆襲》和《敏捷開發法的逆襲》，以及《約耳趣談軟體》和《約耳續談軟體》兩本書，這種以輕鬆風格討論技術的文章集結成書，讓自己也想試試。

無奈，工作之餘，真的很難抽出時間寫部落格，直到 2024，軟體設計相關文章也就 36 篇，其他類型大多十來篇，都收錄進來會失焦，待有朝一日能在其他書中收錄。

聊 UUID 是第一篇在 Medium 上撰寫的文章，後來陸續把 logdown 的文章搬到 Medium 上，但當時忘了一件事，把文章最初的出版日期留下，所以無法在書中給每篇文章確切的出版日期，有點可惜。

這次收錄，稍微根據現況修飾，並根據紙本大小重新排版，讓程式碼不要斷在奇怪的地方。花了不少時間，就是希望它像一本書，而不僅是把網路文章印出來而已。

重新編排的過程中，盡可能維持一樣的風格，像是專有名詞是否用中文或是固定用英文、行中程式碼的字型等。文章收錄的順序，跟當初發表的順序無關，分成心法、套路、摸索以及破繭四個部分，像是一個學徒在學習的過程，自己在每個階段的心得。

所有的文章皆是心得，不是學術論文或教科書，該引用會盡所能標註，論述可能有錯，僅是野人獻曝與大家分享。
