The point is your jitting to an intermediate language thats verified and a system level jit actually turns that into machine code, you are never allowed to write machine code directly to memory and execute. V8 basically does this internally

You still have processes, they just are software isolated rather than hardware isolated. You write everything in a language that can guarantee no unsafe behavior then no hardware checks are needed or any task switching and most of the safet

What unrealistic promise did Apple make? I am curious when they said the app store is "completely secure" because obviously nothing can be completely secure. I know they claim it is "the most secure" app store, which I a

Heat pumps drop in efficiency the colder it gets and only work down to a certain temp. If the outside coils get too cold they freeze up preventing it from functioning properly. would be interesting to know how cold the Tesla heat pump can o

You can run a 1500w resistive heater for 50 hours on a 75kwh battery. I run a 1500w heater in my 30ft RV and it holds comfortable temps down to freezing, in a small vehicle it should have no problem even down to very low temps, 750 watt mig

Not one word on efficiency. Inductive charging is normally pretty inefficient, I would imagine at speed even less so. Seems like it would never be cost effective to do this.

So does the parser generate byte code or ignition? Is ignition just an interpreter or is it a byte code generator too? Does ignition take byte code or is it fed the ast from the parser to generate byte code?

Not really anymore but many phones had Jazelle capable processors in the mid 2000's: https://en.wikipedia.org/wiki/Java_processor

Ignition optionally interprets but always parses javascript, optimizes and compiles bytecode. So IMO Ignition is primarily a compiler frontend that has an optional interpreter back end built in. I could see them splitting Ignition into a by
768.
by SigmundA 5y ago
Right the javascript compiler is Ignition + Sparkplug with the bytecode as IR. Sparkplug doesn't parse or optimize, it relies on Ignition for that, so its not really a full compiler, its just the backend of a compiler. https:/&

by SigmundA 5y ago
Well some processors can execute Java byte code directly, and most of the time its jitted, however originally it was just interpreted.

by SigmundA 5y ago
"The second trick is that Sparkplug doesn’t generate any intermediate representation (IR) like most compilers do. Instead, Sparkplug compiles directly to machine code in a single linear pass over the bytecode, emitting code that matche

I think nuclear is still really important and has a lot of room for improvement. It's hard to beat its output stability and energy density while emitting no carbon. Just have to figure out how to keep it safe.

by SigmundA 5y ago
I wouldn't say you would really count battery discharge efficiency, usually a batteries energy density will be how much useful energy you get out on discharge so it already accounts for charge/discharge efficiency. Same with elect

Batteries are usually wh/kg since wh is what you use for battery capacity. You have to watch it with fuel energy density since it normally doesn't take into account the efficiencies of converting it to useful work and the equipmen

Definitely something I missed when I was more skeptical about BEV's and Tesla a few years ago. It's not about some new breakthrough to make batteries as cheap or energy dense as gas, it's a steady YoY improvement and steady d

by SigmundA 5y ago
So is mutagenesis "direct genetic modification"? How does GMO mean pesticides? I thought that was more under "organic" which is again a very ambiguous and problematic label.

It always amuses me to find that people are against GMO foods yet almost everything we eat is GMO depending on how you define it. Almost every crop and livestock has been genetically modified through selective breeding (domestication). Muta
