If some logic re-orders a job-related queue in order to group similar things, enhancing caches' hit-ratio, then a quite large queue can be quite effective (especially if there is no priority nor barrier, however in such a case the high

Nothing can replace gas 100%. Hyper-nuclearized France always produced (and now produces) between 7% and 12% of their gridpower thanks to fossil fuel (gas/petrol/coal). This is not about 100% but about obtaining a baseload. &quo

"The very architecture of the Chernobyl reactor was faulty", often repeated in some media, is a lie, and therefore the more-or-less implicit "our architecture cannot lead to such a disaster" falls flat.

A nuclear reactor can only do this (depending upon combustible bars state) at most twice per day. This is a severe limitation. France is a leader in this field. Source (French language ahead!): https://new.sfen.org/rgn&#x2F

I understand. Any corrupted government seems a dangerous proposition to me. As for gridpower it means that nuclear is out of the equation (because corruption distorts expertise) in a gov-corrupted nation. Sadly most active nuclear projec

Denormalization adds to the volume of data to read and write, and often reduces the global hit ratio of caches. On most servers the most plentiful and cheap resource is the CPU (not the storage!), and an adequate level of normalization load

The scale of this storage is tied to variability ('intermittency'), and at least a way to reduce it is known: spread out the production units. Case in point: wind in Europe https://www.imperial.ac.uk/news/1805

Sorry but I don't understand. Does 'qualitative' stands here for 'something is missing, limiting what can be done with the device'? What can a FPU do which isn't doable using a CPU?

Indeed. Many philosophers are pretty clear about it (French ones: B. Pascal, A. Lalande...), however it implies cold (dispassionate) heads and (as pointed out here by KronisLV) plenty of time. Most of us, sadly, lack time and only invest
