One oddity of Lorentz invariance is that two non-parallel boosts decompose into a boost and spatial rotation. I've never quite wrapped my head around this and was hoping to get some insight from this simulation. But afaict, I'm no

It's pretty hard for someone to make something worth a billion dollars then sell it, because someone else could make the same thing and undercut you. We even have a word for the way around this: 'moat.' In the 2000s 'net

Thanks, yes I think we had some confusion on the foo() vs parse() and I was referring to foo(). But even for the parse() example, the issue is the aliasing rules (and not the alignment - though that could still be an issue depending on inpu

Maybe I'm misunderstanding. Here is what I'm trying to say. "Accessing an object which is not correctly aligned" - this is UB "As an example of this, take this code: ..." - this (code) is not UB. Is this incorr

The first example is dereferencing an integer pointer. That is a valid operation. Now if that pointer isn't valid (and being unaligned is one of many reasons it could be invalid) then calling the function with that invalid pointer will

The examples aren't really undefined behavior. They are examples that could become UB based on input/circumstances. Which if you are going to be that generous, every function call is UB because it could exceed stack space. Which i

Absolutely. Interestingly, if there's a paper and it's not typeset in LaTeX, I can't help but start predjudiced. "Is this a Word document? These are not serious people."

With the old way of doing things you could spend energy to reduce errors, and balance that against the entropy of you environment/new features/whatever at a rate appropriate for your problem. It's not obvious if that's t

Another interesting thing about the steam engine is much of science in the 1800s was dedicated to figuring out how steam engines actually worked to improve their efficiency. That may be similar for AI, or it may not!

We made an AlphaGo like implementation for the card game Dominion. Certainly not the same number of cards but similar complexity. I have high confidence the same techniques would work for mtg. In fact possibly better as mtg doesn't len

And in fact, the first engines were developed without a robust understanding of the physics behind them. So, the original version of 'engineering' is more closely to the current practices surrounding AI than the modern reinterpret

Seems like it'd be relatively easy to allow one to 'smooth' their income over multiple years. Imagine paying 100 income at 40% tax year 1 and 0 income year 2. A scheme where you could retcon things to be 50, 50, each at say

I don't understand how inflation and risk wouldn't/aren't priced in. You have $1000. You can: put it in your mattress, put it in 'safe' treasury bonds at inflation +a few percent, or yolo it in NVIDIA. Yes if b

The similarity between divine right of kings and inheritance is that an unearned is transferred via circumstances of birth. Your statements seem to extend that further: If you rent an apartment, you the property is owned by an landlord (lor

There's no inherent right to anything, really. The statements in whatever declaration or philosophy are just arbitrary lines. Physical property rights are just as arbitrary as the divine right if kings (and incredibly closely related w

Real world efficiency factors are in the 90s and basal rates aren't constant. The model you're proposing is too artificial to draw conclusions about fasting over a short timeframe.

Thanks for the explanation of some of the interactions I was missing! It's amazing the complexity of what's basically the simplest setup one could think of.

In a classical view of 2 particles accelerating towards each other v x r will always be 0 so B will always be 0 even if the particles are accelerating towards each other. I believe all this holds under QFT [1]. Looking further a redefinitio

Her credentials are her ability to rally support/interest in climate issues. What credentials would satisfy you? Folks with PhDs and political accolades have been speaking the same points for years, and clearly they haven't bread

Yeah, if you could input data set X with quality Q(X) and output data set Y of the same size with Q(Y) > Q(X), you'd really be on to something. But I don't think such a system exists yet, or even close. Inputting the internet,

A chaotic grid would be macroscopically observable because random + random != 2 random, it's equal to 'bell curve'. Everything would be smeared as a function of distance, which we don't see. This characteristic is observ

Imagine there was a grid for space. For simplicity consider a regular grid of size 1unit in one direction and 1unit in a perpendicular direction. If such a grid existed, using one unit of ?something? would move you 1 unit along the axes of
