Regardless of false negative rate, measured positives are always at least as frequent as false positives.

Vaccine progress is of enormous practical consequence. Effective reporting of material information can move markets, and that means it's useful for efficient capital allocation. Of course, there's diminishing returns and problems

The problem might be recursive. If the shortfall is tacked onto the back end of the loan (plus interest), so long as the tenant is solvent it isn't problematic for the bank. If the client takes a write-down, though, the bank takes a

Publishers put up their website because they want people to go to it. They get ad impressions, subscriptions, sales for affiliate links or wine club memberships or whatever their business model is. That said, I don't agree with the gra

Not to rain on anyone's parade, but this looks like a bog-standard interview-style question. It wouldn't be unusual to ask a candidate to "invent" and implement both data structures in a 45 minute session. Not saying up

There's a bookie in the UK called "Ladbrokes". It isn't an externality, but it's thematically similar -- a commonly associated negative consequence of the business model.

I wonder if it's reasonable to talk about some of these things separately from the rest of the economy. San Francisco can't build a bus lane, but it can build the hell out of some software. (You might argue that our productivity h

I'd bet there will be some natural gas generation in the US in non-remote areas in 2030. Maybe not new construction, but gas is cheap, responsive, and already in place. I don't think it'll be completely replaced by batteries

Yeah. I don't like him (not eligible to vote for or against), but the "threat to our democracy" narrative is completely sunk. He clearly has no dictatorial aspirations. Maybe it's just because of events in the lead-up to

Thinking about these as a "verbose imperative language" programmer, I'd say suffix agreement seems to make more sense to me at first glance, and I'd like to hear more about why it might be worse. For why I think it mak

Ah, makes sense. > in the worst case I wonder if typical data is more forgiving. If, for example, we cut an optimal seam down the column n=x, and the DP algorithm tells us that the best seams starting at (0,x-1) and at (0,x+1) are als

Does repeated single-pixel seam-carving minimise energy for the "remove n seams" problem? If not, is the global algorithm in P? Also, I guess this is beside the point, but surely almost all of the DP structure can be reused if you

Ome might as well say that "Some things, like being able to work for Uber's competitors, meant that drivers were never employees." This is a fuzzy line.

My rough understanding of some key mechanics: - Treasury makes bonds and sells them into the market. The market impact of this tends to increase interest rates (cost of bonds relative to dollars) a bit. - The government uses the money raise

Sure, their mistaken proof of the n->n+1 implication could be taken for what it does prove, and such a theorem could be used in other circumstances to prove different things, but that doesn't really bear on any of the claims in th

> it only works for n >= 2 Right, so it doesn't work -- either it's a correct proof of a non-sequitur ("true for n implies true for n+1, provided n meets some criteria"), or an incorrect proof of an inductive step
236.
by repsilat 6y ago
Right, it proves S(2)->S(3), but induction asks you to prove S(n)->S(n+1) for n in general, and not just for some n. The inductive proof doesn't work for S(1)->S(2), so it clearly can't work for the more general n->n
237.
by repsilat 6y ago
It's simpler than that -- the "proof" of the inductive step is just incorrect. It wouldn't be a theorem in a sound logical system.

Yeah. This kind of savings comes up in interesting places elsewhere -- if you make your algorithm run twice as fast but using twice the memory, your time-integrated memory use (measured in gigabyte seconds) remains the same. So if you can

Definitely. Another place the mathematics translates pretty cleanly to is financial leverage. If you take a loan to expand your business and pull forward profits, or even rent property instead of buying it, you take tail risk but in normal
