The largest known prime could be considered a universal scientific benchmark. It is also a concise statement that is trivial to verify. (by "trivial" meaning much much easier to verify than to discover in the first place)

Water fast is when the only intake is water (plus electrolites and vitamines). Basically "eat nothing".

Another solution: train wild dolphins to recognize the goal (e.g. sunken ships), do the scan for you, and receive some compensation in exchange for the work they do (tasty food? play balls?). Should check the depth range of dolphins.

My ideal watch also has: mobile voice & data connection (via eSim), speaker and microphone, camera. Those in addition to what it already has: 1 month battery life, HR and SpO2 tracking, flashlight. Also, blood glocose and BHB monitoring

Given that many people experiment on themselves anyway, I feel it's a pity and a loss for science that the outcomes of those self-experiments are not collected and aggregated. The article itself raises the issue of "lack of clinic

Not to mention that "gauss" sounds deadlier than "tesla" to begin with. Talking about choosing the right units.

But the US is efficiently disentangling itself from the entire rest of the world as we speak; so that argument may not hold anymore in the near future.

Indeed, federations splitting apart -- that's what happens in tough times.

It's clear that alphabetical order is open to manipulation. Down that path and everybody in the scientific career will be named A.A.

The democratic system of checks-and-balances of USA needs to act to contain the Trump individual. After all the current USA government system is not a dictature and thus Trump is not supposed to have dictatorial powers.

I second this. It's nice to wish for the optimizer to do the [almost] perfect job, but sometimes that never arrives. Consider for example the case of AMD GPU ISA (GCN) generated by LLVM: it's been so far from optimal for so long,

But I want fewer cables, not more.

by mpreda 2y ago
Now I must use lots of rather thick cables in my desktop (because I run GPUs). Imagine that the GPU would instead suck up all the power it needs through the PCIe connector, without all those pesky cables. (right now PCIe can provied 75W at

The voltage step-down is already in place, from 12V to whatever 1V or 0.8V is needed. Doing the same thing starting from 48V instead of 12V does not change anything fundamentally, I guess.
22.
by mpreda 2y ago
Step the GPU voltage up to 48V. (anyway you make a new connector that's not compatible with existing PSUs. Why not actually fix a problem at the same time, once and for all! [48V should be enough for anybody, right?])

Exactly. Consider this example: a = f(z); b = g(z); v = x > y ? a : b; Assuming computing the two function calls f() and g() is relativelly expensive, it becomes a trade-off whether to emit conditional code or to compute both

And the splitting into CDNA and RDNA comes from the same direction: market segmentation, to allow much higher prices for the CDNA data-center GPUs, while keeping the gamer-focused RDNA GPUs affordable for mere mortals. Of coures this backfi

It seems AMD has to choose between monetizing the GPUs right now by selling them at the maximum effective price, or forgoing that gain and selling the GPUs at cost and increasing GPU market share in the future. The choice between short-

What is not explained in the article is how China is "weakening the value of its currency". The answer to that question may offer a new insight on the situation, and help decide whether it's good/bad and for whom. As I

There's also a different way of "getting water from food": methabolizing (burning) carbohidrates with oxygen produces CO2 (carbon dioxyde) and.. water. I think that desert mouse eats very dry grain (which does not contain muc
