There's no comparison whatsoever here. My high-speed cargo rail proposal/idea is actually DESIGNED for criticism out of the self realization that I am no expert in the field. I gathered as much data as I could. Did a bunch of math. Studied some of the issues involved and devoted a non-trivial amount of time to understanding the underlying issues.

Had you engaged me privately you would have also realized that I am very aware of the near-impossibility of the project as I proposed it due to a myriad of issues, not the least of which are political and environmental. Of course there's the simple practical fact that it is probably nearly impossible to trench new territory to build a new railroad system in the US today.

The more important point of raising the issue was to highlight the issue of just how badly ocean-based container shipping methods are polluting our planet and creating a situation that is has escalated into the proverbial elephant in the room.

So, yes, I've done a bit more work than the OP has done in truly understanding --in his case-- what operating systems are about, how to write the, why things are done in certain ways, the history behind some of the approaches, what works, what definitely does not work, and more.

And, yes, I have written several real-time operating systems for embedded systems, some of them mission critical. And, no, in retrospect it would have been a far better idea to license existing technology but as a programmer sometimes you don't have the option to make those decisions if you employer is dead set on a given approach.

No, I have never written a workstation-class OS. I know better than that. Today, it would be lunacy to even suggest it, particularly for a solo programmer, even with a ton of experience.

Anyhow, you succeeded at getting a rise out of me. Congratulations. I hope you are happy. It still doesn't change the fact that attacking the messenger does not invalidate anything I have said or prove whatever your fucking point might be.
