You also want to prove that the „optimization“ doesn’t make things slower.

That is something that can be easily found and usually fixed with trivial profiling. I'm more talking about data locality instead of pointer chasing. Once you set up a pointer-chasing data infrastructure changing that means rewriting m

This is decent advice in general, but it pays off to try and express your logic in a way that is machine friendly. That mostly means thinking carefully about how you organize the data you work with. Optimizers generally don't change da

100kph is rather slow. Relative speeds of cars exceed that regularly even on city streets. Relative speeds in excess of 200kph are common outside cities.

Every platform can do ads, but only AI platforms have an agent that can semi-intelligently try to convince the consumers of something.

How much can you bias training to favor certain products before it becomes illegal? That seems like a similar question to "how much linear algebra do you have to do to copyrighted works before copyright doesn't apply anymore"

I believe poor air quality in developing countries stems mostly from lack of technology. Cooking and heating with wood (or dung), no filters on power plants, old cars etc.

To my knowledge air quality in Europe and the US is better than in many places where people aspire to live like the average European or American.

I specifically said „improve“ not „eliminate air pollution completely“.

In the future electric cars and heat pumps will improve the situation.

Pulse propulsion has also been demonstrated at small scales, so I guess the technology is at similar scales of practicality. G forces scale with the square of the velocity, I think.

The technology for energy independence has only been developed in the last few years. Before electric cars everyone was dependent on oil. We’re very close to the tipping point where renewables outcompete everything else and all sectors get

Accelerating something macroscopic to hundreds or thousands of km/s (i.e. the speeds you can achieve with nuclear pulse propulsion) on a ramp that fits on the moon seems quite difficult to me.

I got 1kW for my balcony for 250€. Did your friend pay 5000€ just for the mounting?

Most of the costs for residential solar are installation. Systems that you install yourself, e.g. balcony solar, have payback times below five years (even in less than ideal regions, like Germany). I would assume that labor in Pakistan is a

You can order 2kWh of plug-in-ready battery for 400€ or so on Amazon. That's single digit cents per kWh over the lifetime of the battery. Bigger systems are cheaper.

Balcony solar can still satisfy a significant portion of a household's demand.

by adrianN 11mo ago
My solar system has a battery than smooths out the generation over a day or two so that I can satisfy my night time demand too.

Imo there is a big difference between insulting a person's work and insulting a person themself. People can and do mess up colossally without being losers or monkeys.

Space ship speeds are unlikely to keep ever increasing. In the limit you can’t do much better than turning part of the ships mass into energy optimally, eg via antimatter annihilation or Hawking radiation, unless you already have infrastruc

Humans are born quite prematurely so that the head fits through the birth canal.

The most realistic sci-fi engines are nuclear pulse engines where you ride the shockwaves of thousands of fusion bombs to reach a few percent of the speed of light. Those we could probably build right now if we were willing to spend the mon

Individuals are unlikely to be able to do something about the centralization problem except vote for politicians that want to implement countermeasures. I don’t know of any politicians (with a chance to win anything) that have that on their

It is basic in the sense that it is difficult to run a business where billing doesn’t work. It’s not basic in the „easy“ sense.

Ground source heat pumps as used for heating buildings source their energy from the sun and work very well. They are outcompeted by air source heat pumps despite better efficiency because digging is expensive.

There are lots of houses getting the majority of their heat from ground source heat pumps. Not so many that are heated with vigorous exercise.

Pellworm is something like 95% renewable without storage. That really doesn’t sound like failure to me.
