>That's what's covered by the "assuming you have formalized the statement correctly" parenthetical. Sure. But it's fair to ask how to validate that assumption.

This answer is too grown-up for the forum.

“It takes a thousand men to invent a telegraph, or a steam engine, or a phonograph, or a photograph, or a telephone or any other important thing—and the last man gets the credit and we forget the others. He added his little mite — that is a

Yeah, it's all about the inflection point. Otherwise how are you even dispositive?

Genuine clicks on useful ads are a tiny part of ad revenue. There’s no incentive for media to work on that slice of clicks.

I think you're saying that just running up huge losses is sufficient to create a successful company? But that you personally wouldn't want to run up huge losses? Not sure.

Amazon did borrow money, for a long time.

To become the next Uber, do I just need to run huge losses?

Feynman didn’t write these notes. John T. Neer did. There’s an explanation at the beginning.

Normal students learn the material from normal textbooks. The Feynman Lectures on Physics are a fantastic supplement and a great reference for people who already have a solid background. They’re not a practical introduction. Feynman acknowl

Sure. But at that point the purchase price is much higher than the cost of the research.

We could just keep using "First world" vs "Third world" as above. There are also multiple NGOs that measure these things and break down the "ratings" into component parts. On the other hand, an advocate for gre

Yeah, it's always corrupt. No, it was not always this corrupt. We're aiming for third world. That's going to be a new experience.

Totally. I understand what the claim is. I don't understand why anyone would believe it.

by oh_my_goodness 10mo ago
Yeah. That's totally real. (But I get that it was also funny, and I loved that show.)

by oh_my_goodness 10mo ago
I don't exactly disagree. But the word "obvious" doesn't work very well during a bubble. Sure, yes, the current revenue doesn't justify the purchase price. But that doesn't mean that anything justifies the pu

I don't understand what "low risk" means here. For a start-up, 99% risk of failure is low. What are we comparing that to?

"Pennsyltucky" doesn't necessarily mean "the rural parts of PA." It can mean "the swath of country roughly from Pennsylvania to Kentucky" or "places like that" or it can be even broader than tha

Please don't reinterpret my comment. I didn't say anything about what you're focusing on. I made the simple and clear point that clicking on Pike's name leads to an unattributed quotation that (it turns out) isn't

by oh_my_goodness 10mo ago
Pike's name is what people are clicking on here. That's being abused to sell this random comment about IP.

by oh_my_goodness 10mo ago
To be clear: note that that the quotation that has taken over the focus is not from Rob Pike at all. Not Pike.

by oh_my_goodness 10mo ago
Quotation not from Pike.

Gah, I wrote the wrong thing. If each probability is 50% +- 10^{-6} then the amplitudes are matched to within around 2 times 10^{-6}. But when N>2 this gets tougher rapidly. If we add 10^12 complex amplitudes and each one is off by one

I don’t think we can discuss precision usefully without numbers. We seem to agree on the word “finite” but that covers a lot of ground. “High” precision in rotating an optical polarization to exactly 45 degrees is maybe 60 dB, +- 0.0001% of

Sounds like we agree on how basis vectors work. But you’re talking about the initial state, and I’m talking about the output. Finding a basis that makes the output an eigenvector isn’t trivial. Take Grover’s algorithm. You have to iterate t

When the amplitude has norm 1, there is only one nonzero amplitude. Changing basis does not affect the number of basis functions.
