今天是 Linux 的 24 岁生日。

在 1991 年 4月，芬兰的赫尔辛基大学年仅 21 岁的学生 Linus Torvalds 开始做一个他自己的操作系统。在 24 年前的今天，即 1991年8月25日，他在 usenet 的 comp.os.minix 新闻组中发布了 Linux 的第一个公告，宣布了 Linux 的诞生。以下是当年 Torvalds 写的邮件：

Hello everybody out there using minix -

I'm doing a (free) operating system (just a hobby, won't be big and
professional like gnu) for 386(486) AT clones. This has been brewing
since april, and is starting to get ready. I'd like any feedback on
things people like/dislike in minix, as my OS resembles it somewhat
(same physical layout of the file-system (due to practical reasons)
among other things).

I've currently ported bash(1.08) and gcc(1.40), and things seem to work.
This implies that I'll get something practical within a few months, and
I'd like to know what features most people would want. Any suggestions
are welcome, but I won't promise I'll implement them :-)

PS. Yes - it's free of any minix code, and it has a multi-threaded fs.
It is NOT protable (uses 386 task switching etc), and it probably never
will support anything other than AT-harddisks, as that's all I have :-(.

在该年的九月， Linux Kernel 0.01 发布到了芬兰大学和研究网（FUNET） 上的一个 FTP 服务器（ftp.funet.fi）。当时仅有 10239 行代码。到了十月，又发布了 0.02。
