no it's not, this is a moth not flea

This is a very dangerous way of thinking. You cannot tell at the time of discovery if specific research will be useful or not down the line. You need to advance the research in all directions, even if some of them seem silly or useless, or else you will handicap your progress in other fields which you didn't see the connection with at first.

Why mips and not RiscV? I would assume it's easier to emulate in software and has good support in linux

EDIT: found it

Some architectures had arbitrarily-shifted operands all the time (ARM), some have shitty addressing modes necessitating that they would be slow (RISCV), some would need more than 4KB to even decode instructions (x86), and some were just too complex to emulate in so little space (PPC).

Could it be the pc relative addressing often used on risc-v would be slow to run on 4004?

Funny you mentioned arch, as steam deck os is based on arch, so it is using arch btw

Hydrogen Sulfide can damage concrete, not sure about the chair tho

It's the other way around, you will get all of the tickets which are missing plate info. Some guy did it and regrets it, there is a documentary about it.

I remember when Falkon 9 was doing its first landings, the whole YouTube comments section was filled with flat earthers claiming it's a CGI. Now you can take a car and go watch landings in person, I wonder where all those people went.

The same law which makes gun recoil happen. If you fire a pistol in vacuum you would still get the same recoil or even stronger. The rocket engine fires a lot of gas molecules instead of bullets at much higher velocity than a bullet, which gives it the constant push/recoil

There are cases when electricians working on the street to restore power get shocked by some house generator feeding power back to the grid.

I can't quite understand what is your point? Are you arguing that both JVM and WASM are bad? With this I agree, they both have terrible performance and in an ideal world we wouldn't use any of them.

Are you arguing that JVM bytecode is better than WASM? That's objectively not true. One example is a function pointer in C. To compile it to JVM bytecode you would need to convert it to the virtual call using some very roundabout way. But in WASM you have native support for function pointers, which gives much better flexibility when compiling other languages.

Have you seen what it outputs? The same way we can compile C to brainfuck, it doesn't mean it's good or is useful.

You can't compile C to java bytecode, they are fundamentally incompatible. But you can compile C to wasm, which is what you want for a good universal bytecode. Java is shit.
