I've commuted from NYC to NJ to rent a car with Turo (the AirBnB of cars, which is not allowed to operate in NY). Granted, I probably wouldn't do it again, but I could imagine Jersey City AirBnBs being appealing to NYC visitors on

You could create a JS object with accessor functions that stores an offset, but the object itself still takes up heap space. In Rust, it would just be a (typed) pointer to the position in the buffer and wouldn't require an allocation.

> Any interaction with the page happens through a JS bridge. Right. The point I’m trying to make is that Wasm can only interact with the user through those JS APIs. This is in direct contrast to Java/Flash, which could directly re

Google Docs doesn’t use Wasm, from what I can tell. The move towards using canvas/gl/webgpu over DOM for performance is orthogonal to using Wasm. They go together nicely, but if you’re worried about DOM being replaced, Docs is a g

> the entire game is written in C My apologies, that was clear from your original post but I misread it as saying you were porting into C to use SIMD in Wasm. Thanks for the stats, that's good data to know.

The problem with just moving hot routines over to Wasm is that you pay overhead every time you cross the Wasm boundary. The success stories I’ve heard with Wasm typically involve writing the entire computational core and renderer in Wasm, t

Accommodating in the sense that in a language where you control the memory layout of objects, you don’t have to explicitly do an explicit encoding step, you can just specify a memory layout that the GPU can understand. This makes it a lot n

Sure, but it was meant to refute a pretty weak point that basically boiled down to “I don’t like it so it’s bad”. Enough people do like it and find it fast, and while I can match anecdotes, pointing out the success of the company seemed m

Sure, but presumably the ones that “don’t fit in semantic web content” is a reference to the ones that rendered a portion of the page in Java, otherwise the same could be said about JavaScript.

Flash and Java Applets both owned a rectangle of the screen. Wasm interacts with the page just like JS does. So in contrast to Flash and Java, Wasm fits in with semantic web content to the same extent that JS does.

Web (site) developers will likely never have to learn Wasm if they don’t want to. But people are increase shipping regular application software to the browser as if it’s an OS. Technically you could say the developers of these apps are “web

The company was last valued at $20B so they are doing something right. They are using WebGL. Using WebGL from WebAssembly has some nice advantages; with Wasm you can use languages that are more accommodating to the sort of densely-packed

You can't copyright the GPS coordinates of cities, because those are facts. The data would be the same whether you compiled it or not, and it would be absurd to grant someone a monopoly on that data. If you compile a word list yourself

Ah, you got me! I didn’t realize from reading the TechCrunch article that the repo contained the actual word list, I stand by my original opinion that the takedown was legally valid.

From my point of view, controlling the canonical namespace is a form of soft power in the ecosystem. Since as the post says, the actual files are hosted on GitHub, the cost of the extra load on their infrastructure is real but probably not

Chrome starts a process per tab. On a modern operating system, one process should not be able to starve another equally-privileged process of CPU, so it sounds like there is more going on here.

A more charitable view is that Vitalik is intellectually curious about areas where math/systems meet governance, and that interest led him both to crypto and to writing this blog post. I’m a total crypto skeptic but I didn’t find the b
