The post discusses Fiwix, a small Unix-like kernel that runs on the i386 architecture. Comments reveal mixed sentiments regarding its relevance for students, as it relies on outdated technology that may not transfer well to modern systems. Some commenters express that working with such technologies could limit the understanding required for contemporary systems, while others see the value in learning from historical computing approaches. There's also a mention of Fiwix's use in Bootstrappable Builds, highlighting its role in building the Linux kernel without an existing kernel binary. Additionally, users compare Fiwix with other Unix-like operating systems like xv6 and express interest in exploring alternative programming languages for similar projects. Overall, the kernel is viewed as an educational tool rather than a practical solution for modern computing needs.
