For a few years I worked in the team that wrote software for an embedded audio DSP. The power draw to do something was normally more important than the speed. Eg when decoding MP3 …

Those aren't the only resources. I could imagine XOR takes less energy because using it might activate less circuitry than SUB.

I wasn't comparing the two studies. I was just asking what the first sentence of the abstract of study 1 meant when it appears to be a false statement given study 2's result. Usual…

The abstract begins, "Growing evidence supports early eating to control appetite and energy balance". What does that mean? My unskilled reading of it is that there is recent eviden…

In the UK the wholesale price was about £80/MWh in 2025. The retail price was about £270/MWh + a standing charge. If you factor in the standing charge, an average user paid about £…
