Hello. I have a question regarding Linux/Debian/Ubuntu.
Are there any very good online references/resources from a written historical perspective for Linux including visuals from the dawn or inception of the operating system to the latest developments of Linux, Debian, and most specifically Ubuntu?
It may be a hard copy reference manual you can suggest or recommend as well – free or paid that is comprehensive and detailed. A PDF file would be great! Please provide the URL to that website as well. I would like the information and data depicted not only for a novice, but also an expert could utilize the more complete information too. I am willing to pay, if necessary, a reasonable and prudent cost as long as it is reasonable, prudent, and fair; however free is always recommended of course.
