Proof reading
Does anyone ever proof read the text before posting.

 

Million of lines    (of what)

Kernal as mistyping/spelling for kernel.

 

Please, its distracting when there are annoyances. We think of them, rather than the message.

Linux kernel = Linus' Unix
the Linux community has been accused by Richard Stallman of ignoring the contributions to the operating system from the Free Software Foundation's Gnu tools and components. But many Linux builders and contributors freely acknowledge Gnu pioneered major operating system comjonents. But the kernel remains a new creation, not indebted to other sources other than the precedents and example that Unix set. To my mind, Linux remains Linus' Unix. The penguin mascot, Tux, is an acronym for Torvald's Unix.

Is OpenStack bigger?
Oops. Just saw a claim for the OpenStack Project that it now consists of 20 million lines of code.

Introduction to the Linux
To those interested, rdX (edx.org) offers a free Linux course. According to the site, to cover all the material will take anywhere from 40 to 60 hours.

I was thinking to take it, just to do a refresh. You never know when you're gonna need it.

Re: Is OpenStack bigger?
How does the Linux kernal error rate per thousand lines of code compare with other projects? Is it significantly better or worse?

Minix Coppied.
It was a rewrite of Minix.

Tanenbaum created Minix but his limitation (education only/the source codes were only available to university students) killed it.

Linux caught on fire because it gave free source codes, free distribution, you can make money with it. There is almost no limitation except if you change it you have to give your codes back.

At the beginning, it was just people who want to learn(OSes) + hobbyists. Then companies figured out how to make money with it. Then the rest is history.

If they could not monetize Linux, I don't think it's here today.

BTW: Tanenbaum later tried Linux way but it's too little, too late.

Linux bug rate compares favorably to other projects
That's a fair question, Tom. Jon Corbet's report summarized numbers of defects but I didn't see a ratio. So I turned to Coverity, which scans open source projects for defects and found it rates core Linux kernel code at .61 defects per 1,000 lines. Any rate equal to 1.0 or less is considered "good quality software." The .61 for the kernel (excluding drivers) compares to an average .59 for open source projects overall. That's pretty good because the rate of errors goes up with the size of the project. It's latest report covers Linux through the end of 2013. It doesn't address 2014. Open source in general has lower ratios than commercial code.

App?
While I am writing these lines I am using a Linux system as Ubuntu is, and I can state that the developing rhythm of the Kernel should be synchronized with the developing process of the supporting applications and in this field the results are not good. Sometimes it is really annoying that very good software programs do not have the relative Linux version.

Re: Tinification
If the objective is to reduce the size of the kernel, why not follow SunOs 4.1.4, and include the optional kernel modules (mainly drivers, I assume) as object modules, which the user can statically link with the kernel. The distribution already contains the linker/loader, so a simple modifiable shell script would be all that is needed.

Re: App?
@Nemos,

Is it because the usage of the Linux versions aren't as popular? I guess developers but most of their time into the more widely used platforms.
