wasn't familiar with proot -- with a quick look I think proot is a fancy chroot -- which, in turn, is kind of "the first step" for a generic container.
to achieve the isolation that gvisor offers you would have to intercept syscalls, create a separate mount/user/net namespace etc.
regardless, I don't think proot is somehow related to gvisor ;)
It does though, it has user-space implementations of chroot, mount and kernel syscalls. You can even run a debian image built with a later kernel on an older linux system
At the starting of the week
At summit talks you'll hear
them speak
It's only Monday
You could be sitting,
taking lunch
The news will hit you like
a punch
It's only Tuesday
We'll all go running
underground
And we'll be listening for
the sound
It's only Wednesday
You'll hear a whistling
overhead
Are you alive or are you
dead?
It's only Thursday
Though that shelter is your
home
The living space, you have
outgrown
It's only Friday
Tomorrow never comes until
it's too late
I have nothing to say about Quadratic Programming, so you tell me.
What I can say is that every reference I've found to Bill Gosper's algorithm describes the data structure as an immutable quadtree with canonicalized nodes, id est, there is extensive structure sharing in a Game of Life quadtree. That in turn facilitates heavy memoization.
You are a small minority of parents who have the time, energy, and perhaps money to do so.
I'm not sure the vast majority of parents have any of those and would happily welcome a compromise where they hand their kid a tablet and it's a tame device
