GIMPS is also interesting since it doesn't need to do 2 operand multiplication. It only needs squaring.

I think you want to write: if (s1 == -1) c1 = c0; if (s2 == -1) c2 = c1; These can become conditional moves on x86. I've often thought RISC-V should have implemented an IF instruction instead of compare and branch.

>> Why not give the top limb 64 bits and the other four limbs 48 bits each, then? I think one goal is to use 5 64 bit registers to do 256 bit math. That means using 256/5 = 51.2 bits of each word. That's probably some kind o

I think the Carholic church has decided it's dangerous to accept parts of the Bible as metaphor, so they must force a literal interpretation on everything - even to the point of absurdity. Jesus said it's his body and blood so it

This. There are a lot of biblical teaching about money and how to handle it, and to multiply it. Unfortunately people tend to make that an end unto itself and that was never the point.

How much of that is hindsight? Was she drawn to Y-combinator or did she drift into it like she did Fidelity? Recognizing it was the right people and the right thing obviously happened, I'm just questioning when she actually knew that.

Automation was reducing the number of manufacturing jobs. But "free trade" has taken away a lot of the manufacturing itself. The US as a whole can no longer make the TVs and iPhones that it consumes so many of.
