在 ESP32 跑 Linux 作業系統
在 Hacker News 首頁上看到在有中國的開發者在 ESP32 上跑 Linux 作業系統：「Linux 5.0 shown to boot on ESP32 processor」，對應的討論在「Linux 5.0 shown to boot on ESP32 processor (cnx-software.com)」這邊可以看到。
文章最後面有提到這不是第一次在 ESP32 上跑 Linux：
Note it’s not the first time somebody runs Linux on ESP32, as last year the older Ubuntu 9.04 was demonstrated on ESP32.
看起來應該是作者覺得很有趣，所以還是提出來... 機器是 8MB PSRAM 與 2MB SPI flash：
ESP32 IoT processor supports up to 8MB PSRAM which makes it just enough to run a minimal version of Linux. There’s little practical application for it, but it may be fun to try, and one developer apparently managed to boot Linux 5.0.0 on a board with an ESP32 dual-core Xtensa processor connected to 8MB PSRAM and a 2MB SPI flash.
如果以 8MB RAM 來推算的話，大概是 i386 (80386) 到 i486 (80486) 時代的電腦？不過 ESP32 的 CPU 時脈快不少 (雖然架構不同不太能直接比較)。

LinkSys 將繼續提供 WRT54G (4.0)
在 Digg 看到的消息：LinkSys courts Linux hackers with WRT54G"L"。 LinkSys 的 WRT54G (Wikipedia 對 WRT54G 的介紹) 因為以 USD$60 提供了 4MB RAM + 16MB Flash，而常常被一些 Linux 玩家買回去重新塞自己做的 Flash :p 在最新版的 LinkSys WRT54G (5.0) 因為改進到只需要 2MB + 8MB Flash，於是市場上就開始有收購的熱潮 :p 結果 LinkSys 跳出來說 LinkSys 還是會繼續提供 WRT54G (4.0) 給 Linux 玩家惡搞 :p

超小的 Docker Image
在 Hacker News Daily 上看到「Super small Docker image based on Alpine Linux」這個專案，看了一下是 BusyBox 類的專案，不過套件支援度比起其他 BusyBox 專案多不少。 基於 Alpine Linux 的系統： Alpine Linux is an independent, non-commercial, general purpose Linux distribution designed for power users who appreciate security, simplicity and resource efficiency. musl libc 與 BusyBox： Alpine Linux is built around…
