0.999...=1 is true in the mathematical sense, period.

However as a representation of physical world, there is a caveat. What we understand is physical world appears and behaves discretely, because at planck scale (approx. 10^-35) the distances seem to behave discretely.

Although common people don't know/ understand planck scale, they do grasp this concept intuitively. What they are really saying is that in physical world there's some small interval (more precisely, about[1 - 10^-35, 1]) which can't be subdivided further, based on our current knowledge.

Same thing applies to planck time (approx. 5 * 10^-43) too.

So people are arguing two different things - the pure maths concept, or the real world interpretation.

GPUs are designed to do massive parallel computations which all branch one way and don't have much (any?) branch prediction logic.

You trade it off with increased code size which might spill the cache but for small tight loops not exceeding the cache line/ size it would still be a good win.

Plus, the delay slots are typically _fixed_ 1-5 cycles depending on CPU architectures. The problem is sometimes the real delay could easily be 200+ cycles (TLB/ cache reload, bus contention etc.) and _variable_.

There's no way you could cover all variable latency scenarios with fixed delay slots, unless you have a highly specific scenario like a GPU where you control all the internals.

India has ~18% of world population, and still are way less proportionately as immigrant population.

Genetically, Indians are the most diverse ( next to entire African continent ) than any where else. Religion wise (ALL major ones and many, many minor too), linguistically, culturally too.

By any objective measure group of Indians immigrant will be way more diverse as an immigrant population, unless you define diversity incomplete until a favored group of people is not highly included.

In a highly capitalist world, there's no free lunch; surely most of the immigrant must be bringing great value?

Ok to the point: 5-6 companies have made mockery of the H1B system. Let's not fix issue for suffering people who came legally as the cream of the system, are highest paid as an immigrant group, pay taxes, understand democracy because of 'those' rotten apples?

Ok so what you are saying is that in a 3 country world: US, Lithuania, and Rest, you insist and define 50 Lithuanians and 50 rest is fair, and call out any changes as racist.

By your definition, both a toddler and Arnold Schwarzenegger should both get same 2 slices of bread, because it is 'equal' and 'fair'. Anything else would be ageist?

I wasn't aware that US doesn't need a civil society since a part of the population has made mockery of the system have committed crimes and many are in jail.

Currently the diet is 25 grains of rice, 25 chopped pieces of beans, 25 leaves, and 25 cows.

Unhealthy? Likely. Unfair? Definitely.

The current bill tries to go closer to fairness by weighting based on population.

What if there are only 3 countries in the world, US, Lithuania, and Rest? Would you want 50 Lithuanians and 50 rest and call it diverse?
