Because this thread always needs someone to say the obvious truth: "Screen time" isn't the most useful concept. Maybe it was in the TV days (though with diverse programming it may not have been), but with phones/tablets&

This is kinda like dividends -- if the value of the dividend (or charitable donation) grows more slowly than the AMZN stock, then delaying the dividend/donation a year and giving the invested/grown amount later might mean greate

Usually smartcase does what I want. The only time it doesn't is when I really really want just lower-case characters, but it's a very good heuristic.

Some folk like `34d` so they don't need to press shift. And sometimes set relative line numbers so they don't need to do the subtraction. Others just search for known text, which IMO is a habit I need to get into. I "got&quot

One interesting interpretation: some folk say that if you make money in the market it's because you drove the market towards efficiency. If you bought low and sold high (control for inflation/rates/dividends/whatever) yo

A few days ago there was a "passive income" AskHn[1], with links to similar threads from previous years, and this year there were a lot of "stock market" answers. My scientific ctrl-f survey has the string "stock&

Worth noting: the implied interest rates on other forms of leverage (futures especially) are probably lower still. And though using long-term in-the-money call options might be a bit more expensive, they have the nice quality of having limi

They said IBKR. Margin rates here: https://www.interactivebrokers.com/en/index.php?f=1595 Subject to change at any time, but 1.59% per annum up to $100k, 1.09% up to $1M, and 0.75% after that. Lower rates in some other

I took a bunch back in the day, and I liked Economics of Money and Banking[1] (by Perry Mehrling) more than most other courses. It's partly a history of the American financial system, and partly a tour of some modern financial instrume

They meant by pricing the externalities. An emissions trading scheme can mean that carbon-emitting activities just displace each other. A carbon tax can mean that carbon-emitting activities can result in net reductions in emissions. Road us

Interesting -- there are more rows (incl removed rows) in yours, because the first step in TFA halves the exponent. I guess it behaves more like binary searching the list of numbers than binary searching the range of numbers, which should b

Progressiveness should happen elsewhere -- in income taxes and transfer payments. The road user charges can be regressive without making the whole system regressive. If every part of the system needs to be progressive it's much more di

Actually the negative leap second is "more monotonic" than the regular one. Normally a leap second adds an extra second (58, 59, 60, 00), but a negative leap second skips one (58, 00). Uniquely specifying the four times in the fir

There have been a few articles in the WSJ in the last couple of weeks. (Funnily enough, a Google search for `wsj rcep` turns up mostly articles written in Novembers-- Nov 2020, Nov 2019, Nov 2016...) Maybe this sort of thing doesn't in

Is that an important distinction? Near as I can tell the main differences are, - It's probably easier for merchants to sell in a marketplace than through a retailer, and - Suppliers probably get paid by retailers earlier than they get

Guessing at what Teleb would say: if it rained on 2% of days, and weather forecasts are only good a week out, you'd expect a reasonable model to have the probability sit around 2% until a week or so before the prediction date, then mov

This doesn't work for me. When I "opt out" it just redirects me to old.reddit.com, and then when I go to reddit.com I get the new look again. And the opt-out button is missing on mobile. I think something changed a month or t

The article title and first paragraph also say that 2020 has been the third least deadly year on record (to date). All three things can be true -- bad week in March, good September, good 2020. But March explaining September is more tenuous.

Right, but NZ has had a pretty light lockdown compared to other countries. To use the language of other posts, if the "reservoirs" of influenza were uniformly distributed, we'd expect NZ to have more flu than the United State

Right. Obviously if they put the sign on nothing , no information would be communicated. And the same if they put it on "50% of things" (defined however you like) because everyone knows the median thing isn't a real cancer r

Honestly, it's an O(1) solution depending on choice of data structure, possibly constant-factor more efficient through your program depending on language, and if you're programming on a whiteboard it might also arguably be the idi

I love these papers. In my undergrad (2008?) we read one by Robert Bixby (and others?) on integer programming, where IIRC the authors measured a 10000x speedup over some number of decades because of algorithmic improvements. You can roll yo

As I understand it, you technically never get forced to go public -- you just get forced into reporting as if you're a publicly traded company. At which point most companies figure they might as well.

Maybe so. I think it was a novel idea to me because my intuition around profiling was formed with an assumption of delivering binaries to users, and not running server processes. (It's probably also a pre-internet bias of thinking it w

Ah, I definitely worked in a place where that distinction in terminology was used, but maybe it isn't widespread. In any case, whatever you call either one of them, sampling from production processes can have benefits over sampling fro

For many use-cases FDO ("feedback-driven") can be more convenient and sometimes mkre effective than PGO ("profile-driven"). The difference is sampling prod vs sampling separately in test. The arguments for FDO: - Prod be
