Ummm… I do. It’s not a hard b sound, but it is there. It sort of moves the location of the “t” sound down towards a “b.” It defiantly does not sound like “det”.
And I distinctly pronounce the “b” in “plumber” (another example in the article.
garmaine commented on Ask HN: Were CS classes in top universities more difficult in the 80s than now? · Posted by u/amichail
In the 80’s? What CS classes.
You sidestepped the question about what rules of logic are intrinsic to the universe. There are different versions of logic. Is Law of the Excluded Middle intrinsic or not? A great many physicists, philosophers, and mathematicians don’t believe logic is intrinsic to the universe. Is ZFC intrinsic to the universe? Do large exist as a deduction from the math that is intrinsic to the universe?
The law of the excluded middle is also known as the “sandwich theorem” because it drives directly from a physical observation. I happen to agree with the constructionists that mathematics is better formulated without it, but it is most definitely a rule derived from analogy to the physical world.
As a physicist myself, I’ll tell you that there isn’t a single one which believes that the universe doesn’t operate according to knowable rules. That’s kinda the definition of what it means to be a physicist.

garmaine commented on Ask HN: What’s the origin of the phrase “Don’t feed the trolls?” · Posted by u/jcolman
There are lots of things that wouldn’t exist if humans didn’t exist. The question is whether or not math is one of these things. No one is doubting the existence of mathematics. What is doubted by a great many people is whether or not math exists independent of human existence. If math is an intrinsic part of the universe then is logic also an intrinsic part of the universe? If so is it the standard logic used in mathematics? Does it include the Law of the Excluded Middle?
Math is fundamentally a description of the physical world. Mathematicians don’t like to hear this because they have their own ideas about the platonic realm of math, but it is true. We can debate which logical rules or axioms to include, but fundamentally any math has to have some sort of rules for deductive reasoning, which carry over from observation about the physical world: effects have antecedents, with a causal link between the two.
Now we have gone from that to the present day when we have maths which aren’t yet found to align with physical reality. So I can see why people want to say that it is a mental construction. But still, even these abstract maths operate according to rules we derived from the physical universe.

and what happens with concrete when the ground trembles...? it breaks. apart of that concrete is still damaged by radiation and such wholes and concrete needs to be redone after some years (there's already second one i chernobyl). and then after some years you have a lot of contaminated cement, which you need to cover again... and again... and again... it'll need to be redone even after both you and I die (assuming I don't get to my dream of changing all organs for new ones and living to 500 ;))
There’s not that much radiation in this water. None of those concerns would apply. They could literally just dump it into the ocean without measurable effect, which is the plan of record.
