Sure, you were right. But if you had been wrong and we would now have had superintelligence, the upside for its owners would presumably be great. ... Or at least that's the hypothesis. As a matter of fact intelligence is only somewhat

Natural gas, from the Slochteren gas field, was the cheapest way to heat a home for the past 60 years. It's probably not so anymore, considering the Slochteren field is mostly shut down. The city heating network operator is a monopoly,

The critical point of hydrogen is 33.2 K, that is Kelvin, or -240 degrees celsius. Any higher temperature than that, hydrogen is not a liquid, and exerts pressure on the walls of its container. ... so, you have the choice of making a very s

I don't understand what measure of efficiency you are trying to use, in which Diesel would end up being better. In environmental discussions that measure is usually something of grams-of-CO2-equivalent emitted per km. One oddity is tha

No horse in the race, but: - The Rust compiler uses the LLVM backend, which is generally more aggressive about optimizations and code generation. The Go compiler is a custom compiler (I think plan 9 inherited) and as of fairly recently didn

Thank you for that link! That does look like it is a very similar IR structure indeed. Very interesting.

Hi! Author here. Honest question, because I don't know all the facts: - Given that in this IR, every value has a single definition, and every use must reference that value, I'd argue that this is already SSA form. - In fact, the c

Hi! Author here. I think you hit the nail on the head here. The optimizer is unaware of the control flow, because the control flow is added by the code generator.(And with it, the distinction between computing a value and referencing it

I got that number from here - tried to find a more 'official' source, but water isn't as well documented as energy. Note that those numbers when I last looked into it typically include industrial and agricultural water use -

The current state of the art (reverse osmosis) is already fairly good. The first link I found [1] demonstrates the increase in efficiency - we're talking about roughly 3 kWh/m3. I don't recall exactly, but I think that is in

I just wanted to share that everything jvns is saying here is true. In 2014, for the Google Summer of Code program, I applied to build a JIT compiler for the MoarVM virtual machine. (It is actually more correct to speak of my work as a JIT

I agree fully, synfuels are a hugely naive idea. However, I've been pondering the use of direct-ethanol fuel cells in the place of 'range extenders' that are currently on some EVs. Advantages are legion: ethanol has a ready (
