I've been noodling on sandboxing models
"Before I built a wall I'd ask to know
What I was walling in or walling out"
With computers, this strategy doesn't work. Inside and outside have a way of switching places.
In Unix, the crown jewels were the root user; other user accounts were sandboxed. Code (in C) ran all types erased.
Time passed. Root grew vestigial, people stopped sharing computers. The crown jewels moved to user accounts.
Compare Java, which has strong types within the VM. (At least until generics started erasing some types.)
More time passed. Local hard disks became disposable (chromebook). The crown jewels moved within the browser.
Enter Wasm. Now the browser tab is the crown jewels. Compiling to Wasm erases types.
As time passes, people will start living within the Wasm sandbox.
@akkartik EcmaScript decorators have an idea of metadata, but it's voluntary, & these evil conniving small minded fucks think decoration has to be at load only, erased. cause these small minded fucks don't get what fucking shit type erasure is & are too fucking idiotic brain dead dumb or worse are cavalier "erase all the types" shit nuggets to do the right thing & have decorators actually express themselves in the language. I hate this standards body. conservative fucking jerkoffs.
@akkartik in contrast to these observations, the most interesting web platform work to me is the file-system-access & low level wasm oriented (but not backed by the real user fs) byte level native wasm oriented low level web fs api, whose name right now escapes me.
@jauntywunderkind420 Mu also goes against this. Mu's not chasing adoption, and the model is explicitly geared against running untrusted code. The eventual vision is to share whole stacks, and to run untrusted stacks in separate VMs that are isolated from your "home" computer.
But I'm going through one of my periodic bouts of self-doubt 😄
Revel in the marvels of the universe. We are a collective of forward-thinking individuals who strive to better ourselves and our surroundings through constant creation. We express ourselves through music, art, games, and writing. We also put great value in play. A warm welcome to any like-minded people who feel these ideals resonate with them.
