Linux was born on 1991 right? and Linux is a UNIX type of operating system, Im wondering what is a UNIX? UNIX is very old right? and if the Linux kernel was developed on 1991, is the main developer of Linux w/c is Linus still updating the kernel or the kernel is being updated by the people on the Opensource community? coz if the Linux kernel is not updated then Linux distros wont work like what it supposed to be right? and lastly what is the very first usage of Linux kernel on 1991 and what is the first Linux distribtion

Thnx!

History of UNIX

As far as I know Linus is still the head hauncho when it comes to what gets into the Kernel though other people are responsible for doing the coding and testing. The open source community do make suggestions for inclusion in the "official" kernel but since the kernel itself is open source people and distributions are free to modify it the way they want. Gentoo Linux supplies the standard kernel but also has available a "Gentooized" kernel.

I have no idea what the first linux distro was.

Im wondering what is a UNIX?

UNIX used to be an operating system, now it's a generic term for a group of operating systems that conform to a standard and pay for the rights to be called UNIX.

is the main developer of Linux w/c is Linus still updating the kernel or the kernel is being updated by the people on the Opensource community?

Both. Linus has the final say on what goes in, but patches are submitted by tons of different people.

coz if the Linux kernel is not updated then Linux distros wont work like what it supposed to be right?

If the kernel didn't get updated no drivers would be added or fixed, no new protocols would be added, memory management would stagnate, etc. Basically the only thing changing would be the userland tools.

and lastly what is the very first usage of Linux kernel on 1991 and what is the first Linux distribtion

The very first Linux usage was when it booted on Linus' machine. It only ran on a 386 with an XT hard disk, he even said it would never work on anything but a 386 and would probably never support anything except XT disks since that was all he had. You can tell he was very wrong =)

I think that's right. If not Yggdrasil, then SLS, maybe? Both long gone, now. Of the really early distros, I think Slackware is the only one left.

OK, Unix was developed by Bell Labs, way back in the 70's, at roughly the same time as the C programming language, which by the way, linux is written in. Don't be put off by it's age, UNIX by it's nature is very modular, adaptable, and scaleable, anyone telling you such an old OS is low-tech is. . .misinformed.

Now unix is not just a type of OS, but a specification (you'll see the word POSIX thrown around alot.) Your various unixes, *BSD, linux, AIX, solaris, etc, all share similar interfaces and system calls that make them a unix operating system.

Everyone's favorite finn Linus is still in charge of the very actively developed linux kernel, the development version, the 2.5 series, is maintained by him. Many, many, many other hackers contribute to the development, for example, check out kernel.org, and you'll see the -ac kernels, these would be maintained by Alan Cox of Redhat, lots of the major distros employ kernel hackers. Just take a look at any of the Changelogs on the same site, and you'll see a small glimpse of just how many people contribute.

It's also not only the linux kernel that has to do with the progression of the major distros, the GNU (GNU is Not Unix) Project is responsible for many, many, many programs that go into making a GNU/Linux distribution. Those great software development tools that make linux progress? Thank you GNU.

As for the first distro, I believe slackware (strokes slackware mousepad on desk. . .Got Slack?) was the first commercial linux distro. Not sure about older non-commercial distributions.

And btw, the very first usage of the linux kernel in 1991, was on Linus' old box, a famous Linus quote tells how he never imagined that it would ever be ported to more than that old hardware.

Silly Linus. :)

I just edited this in. . .when I realized how similar my response was to Nothinman's. . .allwells, way for me to look like an ass, and Nothinman, way to link to Debian :)

I thought that SLS (upon which Slackware was orginally based) was a commercial distro as well. Ah well, I suppose lwn's timeline would have this stuff in there. I do know Slackware is the only commercial distro that has always been profitable :0) (it is such a nice mousepad btw ;0)

most unix systems have (BSD, Solaris, etc) are based on the System V base, and share some code and design philosophy, Linux however is not Unix, it has no Unix code and it does a lot of things in a different way from Unix. Linux refers to the kernel, thats it, everything else -- utlities by GNU, which also exist on unixes,

just my 0.0002 cents

Ooh.. nice link to Bell Labs. Btw, one of the "creators" of Unix at Bell Labs is now an adjunt professor at my college. :D
