Of course containers are complicated! The kernel's documentation for cgroups is 13 separate documents! You can't even "download" a container without a complicated tool to "manage" it on the disk! They are quite complicated.
Also, cgroups aren't containers. "Containers" is a loosely defined concept encompassing Linux's common implementations of cgroups and namespaces and chroot environments and networking and union filesystems. Complicated x5.
Also also, that eli5 assumes a lot of Linux knowledge most five year olds don't have.
That's like saying world wars are beneficial to humanity because a bunch of shit gets invented to fight wars. No. Wars and so far space travel has done nothing for humanity. If you would have instead focused on inventing the inventions that came with fighting wars instead of fighting wars we still would have the inventions but would have been much more efficient.
Not really. That's not how the world works. Otherwise we'd have jumped from stone age straight to nuclear energy.
The way this works: space exploration presents a set of compelling engineering challenges that extend our capabilities. People solve those challenges, and then other people find more mundane uses for resulting solution. But without the initial compelling challenge, those inventions would likely either took much longer, or would not have been made at all, because ones on the market were good enough.
And that's just talking about trickle-down benefits. Then there's the whole lot of direct benefits from satellites - from the most obvious, like navigation and communication, to the less obvious, like weather monitoring, agriculture management, emergency response, national security, climate science, etc.
But he did find out since you told him. That's the whole reason you don't need to read news because if something in the news is actually important you will find out from people talking about it.
Except the article contained non-functional concepts in it also. But hey at least you got to announce the fact you use/like functional programming languages.
That's my project, and it seems to be surprisingly popular, yet something I've never really received any feedback on.
At the time I wrote it I was modeling the opcodes on the Z80, but I guess I simplified once I'd got it working enough to make myself happy. (Lots of toy-virtual machines, of which this definitely is one, don't implement labels or "decompilers".)
A much better eli5: https://jvns.ca/blog/2016/10/10/what-even-is-a-container/
