I'm rather sure that means since the super computer builders are building their own OS out of Linux, they don't have to supply anybody the source as their not sharing it. However I may be mistaken...
You are mistaken. Top 500 shops are regular contributors to mainline Linux development, with test cases, patches and more than a few core developers. They do it because they benefit from it, and they save money that way, they don't need to carry patches. And they aren't "competing" in the commercial sense, they just want the best system they can have, and that means, play with the community.
anybody here that knows the contract of Linux that can verify this?
Contract??? You really don't get it, good luck with that.
Oh I know, right? But the big fact you danced around is, Linux is just better than the others. It's faster and more reliable. Otherwise top 500 would not use it. Like, they tried to use Windows, they really did. Microsoft was paying academic institutions to install it and providing teams of free engineers. Still didn't do it. Why? Windows can't handle the load, it can't run continuously under load. It just gets more and more unstable then it falls over. Even when it does stay up, it can't touch the storage, scheduling or memory management efficiency of Linux.
Seems like posting that is just an easy way to be dismissive of other people's views. Honestly, couldn't I just claim that your post what's truly whiny in this situation?
Please fee free, and I will dismiss you as a whiner, as is right, good and just:)
Sounds like whining. Remember when Linux was available on PS3? I did not personally use it, but - surprise - I ran into people who did, and never would have been exposed to Linux except for that. And they got pretty pissed when Sony took it away, to the extent that one just stopped accepting PS3 updates, but that's another story. I expect, a whole bunch of people are going to meet the real Linux for the first time because of this, and some of them are going to go on to be active community members. See, just one of those is worth more to the world than 1000 whiners.
There was a time period of half a year or so when the Linux kernel was compiled using C++. It bought worse optimization, much slower compilation, strange bugs. No actually tangible advantages. Finally, Linus reverted that decision.
Wow, compelling story! It would be even more compelling if it were true. Link please.
Yup, it's basically "I somehow never managed to learn C++ so I want a pony." Nothing against Rust or Python, mind you, but C++ rules the world of high performance programming at the moment, and the more billions of cloud servers we have, the more that doesn't change.
You are right that there are more RTOS computers out there than the sum of all general purpose computers, including personal, handset and data center. However, you are most probably not right that any one RTOS covers more devices than Linux does. Hell, I strongly suspect that my thermostat is running Linux, judging by the web connectivity options it has. And Wind River, one of the biggest vendors in the RTOS space, has been offering https://www.windriver.com/prod...>its own flavor of Linux for years. Plus, Linux is an RTOS of sorts, don't you know? With the real time patch, Linux works pretty well at the millisecond range hard response level, and has pretty much invaded that space. Microsecond-level hard latency is still ruled by the specialized RTOS. Linux can do it (see Xenomai) but its something of a force fit. Most likely, the most common OS today is still "no OS". What do you think runs the tens of billions of controllers in dime-store toys? Not Linux, not any OS at all in most cases, these things are coded right on the metal.
From everything I've read, this started before the smart phone craze, some where around 2007-2008. With that being said, they had a very good head start which may still allow them to claim the biggest installation base.
Most of those PCs are in landfill today. I guess somebody just pulled the claim out of their ass.
Due to MINIX's presence on every Intel system, the barebones Unix-like OS is the most widely deployed operating system in the world.
I seriously doubt this claim. Phones have outnumbered PCs for years, for one thing. And Linux is deployed maybe even in more TVs and routers than phones, and numerous other embedded systems, now increasingly including cars. Anybody with decent stats on this?
Maybe it will be more clear if I put it this way: nobody refers to Android as "Android/Linux".
And I said "speak for youself". I, for one, refer to it as Android/Linux from time to time, which invalidates your argument right there. Hey, is every Googler a pretentious asshole, or just the ones who appear in public?
So now you pretend that you have never heard Android called Linux. You are, excuse me for putting it bluntly, a liar. And on the smoke/fire principle, most likely a poor developer as well. I hope I never have the misfortune to encounter an application you had anything to do with.
Yes,.gov domains are highly skewed, apparently towards the wealthy as evidenced by their showing iOS as far more popular than Android while other sources show Android with about 2/3 of the mobile website browsing marketshare.
And Android has more than 80% of the phones, so agreed, the gov numbers are highly suspect.

Failures on supercomputers are usually hardware and not software related
Specious. Failures on supercomputer bring-up (where the big frontend engineering costs live) are usually software and not hardware.
Who says these super computers are running a free variant of Linux?
I do. There is no such thing as a non-free variant of Linux.
I'm rather sure that means since the super computer builders are building their own OS out of Linux, they don't have to supply anybody the source as their not sharing it. However I may be mistaken...

Linux was originally made in Finland.
It will take a lot of courage to keep the notch.

...you buy an expensive docking station to make it work...
Is $93 expensive? (Checkout price on amazon.)
Had to be said. Java is not a good OS foundation.
Java is not the foundation of Android, it is just the language that (most) apps are written in. The Android libs are written in C and C++.
Oh, you mean, like a laptop?
Everybody who installs, uses or provides Linux is unoriginal. By that measure, unoriginal is fine.

We tried really hard with 2.4 and 2.6 kernels, and could not come near the vxworks performance for a wireless BS/CPE.
By the way, Linux seems to work out fine for these guys and you already know the license cost.
What is "it", PREEMPT_RT or Xenomai? Not doubting your report, but 2.4 and 2.6 are both ancient.

Excellent survey of real time options for Linux

Have a nice day, Ivan
Wow, are you as bad at developing as you are at listening?
Speak for yourself.
