➤ 透過逆波蘭表示法展示 Lily 的現代語法特性
✤ https://lily-lang.org
本文介紹 Lily 程式語言的特性與實作範例,該語言採用靜態型別系統並內建直譯器,透過參考計數與垃圾回收機制管理記憶體。主要展示如何使用代數資料型別、例外處理與泛型等現代語法,實際編寫逆波蘭表示法計算器,演示包括字串解析、堆疊操作及多層錯誤捕捉等技術細節。
+ 「沒想到函數式語法與模式匹配能如此簡潔地處理運算邏輯!」
+ 「記憶體管理機制與 C 語言的互通性對嵌入式開發特別有用」

SaaS is the most profitable business model on Earth.1 It’s easy to understand why: build once, sell the same thing again ad infinitum, and don’t suffer any marginal costs on more sales. I have been writing software for more than half my life. In the last year itself, I’ve talked to hundreds of founders and operators in SF, from preseed to Series E companies. And everyone is constantly talking about the threat looming over the industry, that has changed how our entire industry thinks an operates: agentic AI a.k.a. your very own overzelous intern that always listens to you, available almost as cheaply as drinking water from a tap2 This isn’t just talk – the market is pricing it in. Morgan Stanley’s SaaS basket has lagged the Nasdaq by 40 points since December. HubSpot and Klaviyo are down ~30%. Analysts are writing notes titled “No Reasons to Own” software stocks. This is bringing an existential threat to a lot of B2B SaaS executives: How to keep asking customers for renewal, when every customer feels they can get something better built with vibe-coded AI products? The market is reflecting our new reality (Source: Bloomberg) Whenever I bring a new friend to the Salesforce Park, they are in absolute awe. And, the meme remains true that no one even knows what Salesforce does. Whatever they’re doing, they’re clearly earning enough revenue to purchase multiple blocks in SF. ↩ if you’re a tech company in SF, that is ↩
Something strange is happening with Mac Minis. They’re selling out everywhere, and it’s not because people suddenly need more coffee table computers. If you browse Reddit or HN, you’ll see the same pattern: people are buying Mac Minis specifically to run AI agents with computer use. They’re setting up headless machines whose sole job is to automate their workflows. OpenClaw—the open-source framework that lets you run Claude, GPT-5, or whatever model you want to actually control your computer—has become the killer app for Mac hardware. Not Final Cut. Not Logic. An AI agent that clicks buttons.
