FTA: “Now the SHD Group's forthcoming estimates raise this number to 21+ billion chips by 2031, eclipsing $2 billion in total revenue by this point“ That’s about $0,10 per CPU, so we’re looking at low-performance units. Also, Intel’s

Is that possible? I think you would have [1] to use a register to build up the immediate value. The assembler cannot/should not default to one, so I think the best one could do is having another macro for ADD that takes that helper reg

To be fair, when they started, they intended to write a browser from the bottom up, including such things as image and video decoders, networking, etc. They changed course.

It still would mean a company cannot really offer to do repairs for you, wouldn’t it? They’d have to be able to prove that none of their employees looked at the design documents, ever.

Given Rust’s memory safety goal, IMO the proper way to solve the circular reference problem in the context of Rust would be in the language. It should have a way to express what cycles may exist, maybe also how the code will break them when

We also have Python bytecode. One thing that sets Wasm [1] apart is that, the Wasm virtual machine is significantly lower-level than JVM, .NET or python virtual machine. That makes it a better target for compiling C but also means different

But given a file in this format, you cannot know whether your native decoder can read it without running WASM; the file you read may use a feature that was invented after your library was written.

Sum and custom formatting are idempotent. It doesn’t matter whether that gets run once, twice, or a hundred times. Arbitrary AppScript isn’t guaranteed to be idempotent. You have to run it only once.

The embedded WASM makes this more extensible, but still, they have to choose, and freeze forever, interfaces that the WASM blocks can implement. Chances are that will, at some time, become a pain point. They also have to specify the WASM ve
