卡拉今天看了什麼GitHub - ading2210/linuxpdf: Linux running inside a PDF file via a RISC-V emulator<blockquote><a href="https://readhacker.news/s/6nfht" rel="nofollow noopener" target="_blank">Link</a></blockquote>📌 Summary: 本文介紹了一個名為 LinuxPDF 的專案，該專案使得 Linux 系統可以在 PDF 檔案內透過 RISC-V 模擬器運行。此技術運用到 PDF 檔案格式中所支持的 Javascript，並透過 Emscripten 將 C 程式碼編譯成 asm.js，進一步載入修改過的 TinyEMU 模擬器。雖然在 PDF 中運行 Linux 存在性能問題，但這一創新仍能展示 PDF 檔案的多元性及其潛力。 🎯 Key Points: - LinuxPDF 專案能讓 Linux 在 PDF 內運行，基於 RISC-V 模擬器。 - PDF 格式支持 Javascript，但瀏覽器的 API 限制了其功能。 - 提供了 32 位和 64 位的根檔案系統，默認使用 32 位版本。 - RISC-V 模擬器運行速度較慢，Linux 核心啟動時間約需 30-60 秒。 - 使用者可透過克隆專案並運行指定指令來建置系統。 🔖 Keywords: <a href="https://social.mikala.one/tags/Linux" rel="nofollow noopener" target="_blank">#Linux</a> <a href="https://social.mikala.one/tags/PDF" rel="nofollow noopener" target="_blank">#PDF</a> <a href="https://social.mikala.one/tags/RISC-V" rel="nofollow noopener" target="_blank">#RISC-V</a> <a href="https://social.mikala.one/tags/Emscripten" rel="nofollow noopener" target="_blank">#Emscripten</a> <a href="https://social.mikala.one/tags/TinyEMU" rel="nofollow noopener" target="_blank">#TinyEMU</a>
