LFX 2026 First Stage Key Takeaways in WasmEdge

English Version

In February 2026 I happened to see the LFX program on social media and discovered that WasmEdge was one of the participating projects. After looking into it, I learned that LFX is similar to Google Summer of Code but organized by the Linux Foundation. At the time I was in my second year of graduate school; my thesis was progressing smoothly and I had fewer courses, and because I was interested in open source and the Linux Foundation, I decided to apply. I also wrote a few posts to learn more.

The first phase relied mainly on written communication. Mentor YiYing gave me a lot of concrete advice during both the design and implementation stages, and most coordination happened through GitHub issues and pull requests. The mentor reminded me about review timelines and priorities, which helped me submit and revise on time. Since I had some prior collaboration experience, I was already familiar with PR workflows and code review interactions, which made the collaboration smoother.

On the technical side, I implemented code primarily in C++. During the process I realized my C++ proficiency still needs improvement; at the same time I gained a deeper understanding of WebAssembly (Wasm) use cases and what a runtime like WasmEdge needs to consider—performance, memory management, API design, and extensibility. The implementation work moved me from abstract concepts to concrete engineering details and taught me a lot of practical lessons.

I’d like to thank Mentor YiYing and all the WasmEdge reviewers (including hydai) for their guidance on code reviews, design discussions, and testing. I will continue looking for tasks I can complete in WasmEdge and apply the lessons learned from LFX Phase One to my future development and research.

我在 2026 年 2 月偶然在社群媒體看到 LFX（Linux Foundation 的專案實習計畫），發現 WasmEdge 是其中一個參與專案。查了資料後才知道 LFX 類似 Google Summer of Code，但由 Linux Foundation 主辦。當時我正值碩二，論文進度穩定、課業較少，又對開源與 Linux Foundation 很有興趣，於是決定嘗試投遞申請，自己也寫了幾篇 文章 了解。

整個第一階段的工作以文字溝通為主，Mentor YiYing 在設計與實作階段都給了我很多具體建議，溝通主要透過 GitHub issue 與 PR 進行。Mentor 會提醒審查時程與優先順序，讓我能按時提交與修正。因為我之前有類似的協作經驗，對於 PR 流程與 code review 的互動比較熟悉，這讓協作過程順暢許多。

技術面上，我主要以 C++ 撰寫程式碼，過程中發現自己在 C++ 的熟練度還有提升空間；同時也更深入理解了 WebAssembly（Wasm） 的應用場景，以及一個 runtime（像 WasmEdge）在設計上需要考量的要點，例如效能、記憶體管理、API 設計與擴充性等。實作過程讓我從抽象概念走向具體工程細節，學到不少實務經驗。

在此特別感謝 WasmEdge 的 Mentor YiYing 與所有 reviewer（包含 hydai）在 code review、設計討論與測試上的指導。未來我會繼續在 WasmEdge 上尋找可完成的任務，並把在 LFX 第一階段學到的經驗應用到後續開發與研究中。
