It has been 30 years since the formation of the first public release of the Linux kernel. The 0.01 kernel was 62 KB compressed, included 88 files, and contained 10239 lines of source code. According to Linus Torvalds, the moment of the publication of the 0.01 kernel is the real date of the 30th anniversary of the project. included 88 files and 10239 lines of code.
Linus wrote on the Linux kernel developer mailing list:
This is just a random observation to let people know that today is actually one of the major 30th anniversary dates: version 0.01 was uploaded on September 17, 1991.
The 0.01 release was never publicly announced, and I only wrote about it to a dozen people privately (and I don't have the old emails from those days), so there is no real record of it. I suspect the only date information is in the Linux-0.01 tar file itself.
Alas, the dates in this tar file are the dates of the last modifications, not the actual creation of the tar file, but it looks like it happened around 19:30 (Finnish time), so the exact anniversary was technically a few hours ago.
Thought it was worth mentioning this, as despite being unannounced, in many ways this is the actual 30th anniversary date of the actual code.
