If windbreaker A let's in 2 units of wind out of 100 and windbreaker B lets in 1 unit of wind out of 100, that means windbreaker B is twice as effective at blocking wind, because it lets in half as much wind as windbreaker A.
Slightly different motive though.

If your car is hanging out all day at a parking spot, say in front of your office building, or just on the streets, it might actually charge a large battery enough to get you a chunk of the way through your trip.

It could make plug-in hybrids the norm, even if you don't have a place to plug. For many people, their cars sit idle 80% of the day, if not more. Even if it charges enough for a quarter of the way to your house, that's a quarter more of not needing fuel.

Right now I fill up my regular prius once a month. With this I can see that changing to once every 3-5 months. A potential of course, not saying this will work.

Wolfram alpha was pretty impressive when it came out, and remains on of the best ways to do quick back of the envelope estimates. However, the lack of improvement over the years has been very dissappointing. My subjective experience has been that capabilities been steadily broken or removed. It used to be possible to do an ideal gas calculation for example, by just typing something like "10^10(boltzman constant)(room temperature)/(1 liter). Good luck making that work now. They also continue to persist with their nonsense subscription model where they refuse to sell institutional licenses so they can ultimately extract more money from students.

Yeah, I think if they wanted to do this properly, they would use a projector to get the perspective exactly right from the actual vantage of the typical driver, including cancelling out the curvature of the road for the blocks (but not the shadow).

Fun fact: The speed of light is only constant by convention. There's a nice creationist paper where they try to twist physics into a pretzel in order to make it fit the biblical narrative, using a convention where the speed of infalling light rays is infinite, but the speed of outgoing ones only c/2.

Of course, any such attempt will eventually fail due to invariants that are independent of convention, such as the age of the universe as measured by an observer following the Hubble flow.

One can't help but be impressed at least a little bit by the ingenuity of it all, though...

I think you're just pushing an agenda. Where does the blog say anything about opinion being ranked down.

In terms of what the blog actually talks about, "Democratic debate" is a terrible example. This seems to focus on boosting older articles that break the news and down rank low effort follow up stories. I don't think a consistent topic like "Democractic debate" is a good test bed.

Uber is THE taxi company and WeWork is THE co-working company. All over the US, and even outside of that.

But it does. A lease is somewhere between a capital expenditure and a normal expense. It's not a tangible asset like a building is so it can't be factored into the book value and are instead ongoing liabilities. In WeWork's case, these are multi year leases that cost almost as much to get out of as to pay outright.

>had me thinking it had some clever way to pick a random number from 1 to n in finite time. But that's not actually possible to do with a random bit source and a non-power-of-two n

I can sample 1-6 in finite time by rolling a die. I suppose you mean given a RNG in range 1-2^n, you cannot get a sample range non-power-of-two in fixed time.

However, you can sample in finite time with probability as high as you like, since the likelihood of another roll falls off exponentially. So if the odds of your machine quantum tunneling into a star is p, then you can make an algorithm that does your sampling with fixed time T with probability more than 1-p, making it perfectly usable.

in practice, resampling rand takes very, very little time. I use it all the time for uniform [0,n) queries. The avg number of rolls is for the most part like 1.1 or less.

For example, to sample 0-9 given a 32 bit full period generator, since 2^32 mod 10 is 6, only in 6 cases out of 2^32 cases do you need a second roll. This is common.

The point of market competition is that you can't do some certain things to make sure your output is productive.

You can go and kill your competition and that would also be competitive - but we don't really want that kind of behaviour so we have rules against this. When you're breaking and undermining those rules you are being anti-competitive - you are subverting market competition.
Well, although many now understand WeWork isn’t a tech company (and some of us were saying this YEARS ago — I personally said this at least twice on CNBC as far back as 2014), WeWork raised money and did it’s IPO roadshow and achieved the valuation it has achieved by positioning itself as a tech company, even tho it is just a real estate company with slightly complicated owning/leasing structures.

Soft Bank invested what if has invested, expecting to get the return it would get on a tech company — not real estate.

The reckoning that is happening now is much deserved, but if WeWork got the benefit of being called a tech company when it was flying high (and it did — including here on HN), I’m not going to give the company or its investors an “out” now that it’s all falling apart.

This was a decidedly non-tech company that convinced its investors it was tech. And now that the rouse is up, the bloodbath that follows begins in earnest.
I don't think that's the claim at all; Rather that there is a common but unrealistic, if not downright dishonest, narrative about opportunity and working class jobs and it is doing a disservice to people. It's also plausibly a tool for people in other economic sectors to pretend any problems these people have are "their own fault".

I think that thesis is pretty defensible. Clearly a liberal arts, or for that matter professional, degree isn't for everyone. On the other hand, pretending that some sort of idealized working class living exists in the US today for anyone who just wants it enough and will work hard is disingenuous at best. There has been a lot of cynically dishonest political rhetoric around these topics in recent decades.
Hacker News has a pretty cool archive feature. I'm certain if you go back about a decade you'd see a similar response on anything regarding Internet Explorer. It was the most dominant browser, by a wide margin, even when there were browsers many felt had long since improved beyond Internet Explorer. And those alternatives came from companies that didn't have the reputational issues of Microsoft, somewhat ironically Google was one of them.

Yet today it's become the same thing with Google. They had a phenomenal search engine, but it's gradually gotten worse while other engines have taken some big strides forward. Its marketshare is just completely out of wack with its capability, and so I think that motivates people pretty strongly since it indicates a knowledge gap in the market. This is also a pretty new thing which further adds motivation - a few years ago Google search was, without doubt, king. Now, it's not. And, again similar to Microsoft, Google is increasingly destroying its reputation so it feels good to swap, let alone when other services are now also arguably superior!

To see some degree of evidence of this look at posts related to Google, but not their search. Posted just today (so there's going to be a large overlap in users) was this [1] post where a sunken car (found to contain a corpse) was visible via Google Maps. Nobody decrying Google Maps because it's still the clearly best service for satellite/street imagery. Gotta give the devil his due.

> Legally, I don't know if there is an issue with that, but I see a moral one: you shouldn't be bringing a company public if you can't think it will grow further. It's a misuse of the public markets.

How so? The point of a market is for willing sellers to make deals with willing buyers. What person would sell a company (or any asset) when they thought the public market undervalued it?

My SO is a dermatologist. Her father is also a radiologist, which is probably the most obvious target for this sort of thing. When I asked her about it, she said that she's looking at the depth and height of things a lot, a dimension not really captured in a photograph. This study pit their AI against dermatologists getting the same photo and information, but I'm curious how it'd do against an in-person examination.

Google doesn't appear to be claiming that they could replace dermatologists with AI entirely. Lest anyone's mind start leaping in that direction, here are a few more reasons why I think her job is safe for the foreseeable future.

- Much of her work is full-body skin-checks. How able would an AI system be to provide instant feedback on everything sketchy it sees? How comfortable will people be with, rather than a doctor inspecting their entire body, having pictures taken of their entire body?

- Her cases can get rather complicated. Skin problems can be caused or complicated by internal illnesses that need to be considered. This point, in particular, calls on her specialized training beyond what a GP would have.

- There's a lot more to her work than diagnosing. She's also prescribing treatments, monitoring progress, performing surgeries, etc.

- Her time is indeed very expensive (much to by benefit), and more so than a GP's. But there are a lot of challenges involved in deploying things in medicine, and our regulations are probably unprepared for diagnosis-by-computer. I expect it'll be quite a while before, say, a GP augmented by an AI is price-competitive with a board-certified dermatologist.
That sounds more like a continuation of the trend toward turning prospectuses into marketing materials. "Looking" and "believing" don't translate into concrete action. All this is marketing-speak, and I don't think any of it contributes real value.
Right, "velocity" is a more formal and scientific term, so it must be the more correct one.
According to examples in the English Wikipedia, the method I described above is actually the Fisher-Yates method (and its naive implementation, and thus the O(n²) complexity), and the swapping method on everyone's minds was actually Durstenfeld's (optimization?), with O(n).

The initial code snippet intended to be Durstenfeld was erroneously an off-by-one Sattolo implementation, which then further solidifyed my suspicion that it had a bias, which Sattolo's implementation actually indeed has. The Durstenfeld method is however proven to be unbiased.

To add further confusion to the names in the issue, though some readers might not be able to verify due to the language barrier, the German Wiki states (claims?) Fisher-Yates is Durstenfeld's method with O(n), and the "naive" Fisher-Yates is labelled as the "direct" approach, with O(n²). The name Durstenfeld is not mentioned anywhere on the German Wiki. Though the names are different, the maths are the same in both English and German. I speak German and often read both versions of an article, in case anyone's wondering why I even brought up the topic.

Thank you for posting the link.

EDIT: I try not to post usernames in text, in case anyone ever changes their name.

EDIT2: I recommend to always positively increment an iterator from 0 to n-1, and use in-loop arithmetics to get the actual desired iterator/index you require. It's less performant, but I'd argue mistakes are less common.
Toyota is a hype machine right now. They're trying to mask how they are missing the EV opportunity which they squandered on hydrogen.
I think this is one of those things where the meaning has evolved over time, at least as someone who's been on Slashdot since the early '00s but only joined HN a few months ago. Originally, you'd only see "TFA" as part of RTFA, generally with the assumption that the person you're replying to had not read the article. ("If you'd RTFA, ..."; "Maybe you should RTFA.")

But "TFA", although it derives from "RTFA", never seem to had the same negative connotations. It's just that sometimes you want to refer to the original article in question, but "original article" is long to type and/or ambigious. (Do you mean the news article from the NYT, or the scientific paper the NYT article is reporting on?) And "TA" is too short for people to clearly know what you're talking about (And did you mean "teaching assistant"?) "TFA" is short and unambigious: it always means the article linked to from the main page.

Long story short: Although etymology would suggest that "TFA mentions this" is as aggressive as "Maybe you should RTFA", in actual developed usage, they're very much not the same.

It's true there's a non-zero chance the property market implodes, but the shift to remote workers is exactly what WeWork is counting on. Many (even most) people chafe at working in their living space 100% of the time, and squatting in coffee shops and the like also has its limits. People generally need a work place that is separate from their living place, even if their work place is not the same work place as the rest of their company. Throw in the need for quiet places, conference rooms, whiteboards, etc, and before you know it...

In Google, after that card, I get their "People also ask", and the second question is "What is the average packet size?", which links to https://superuser.com/questions/964682/what-is-the-average-s...

Seems ok to me.

It should also be noted that the etherealmind.com link doesn't actually contain the word "typical", so if you think Google should try to outsmart users less, it's not reasonable to blame it for not showing that link.
I believe a lot of this thinking arises from our perception of time and history. We often perceive the past only as "things that happened" and forget about all the things that could have happened. There was an article posted recently about "near-miss" analysis of events that almost-happen which discussed something very similar.
Yep. Not sure what do these questions try to go after...If Google stops being useful, just quit using it.

Apparently, Google's search algorithm is one of the most hidden secret in the world, and has insanely complex evaluation mechanism in place, any anecdote feedback is not going to cause a ripple in shaping this algorithm.
The reason for naming the variables as they are seems to be to keep consistency with Vitter's paper [http://www.ittc.ku.edu/~jsv/Papers/Vit87.RandomSampling.pdf] Since the paper is really the primary documentation of the algorithm this makes perfect sense. Renaming the variables to be more meaningful to you would make it harder to compare to the paper, reducing the effectiveness of the paper as documentation and making it hard to compare the code to its specification.
They aren't mutually exclusive. I do however suspect that the cost of some paint is a lot cheaper then permanently monitoring and prosecuting these drivers.
Also, for prosecution to be effective as a deterrent requires the driver to make a rational decision about the pro's and con's of being irresponsible, is that a reasonable expectation?

This is somewhere between a gimmick and a break-even solution for daily driving under certain circumstances...

But it's my impression that there hasn't been an industrial-scale effort on mobile solar panels that optimize power/weight/limited area like this. I guess maybe some of those camping panels.

But if a car can self-power it's daily driving range, and we could get spray-on/paint-on solar (remember that?) with functional yield at reasonable cost... why not?

The ideal intermediate electrification step isn't all-battery, as much as I'd like that. For "consumer" driving it's PHEVs with decent all-EV range (40-80 miles)... that maximizes the somewhat restricted (currently) battery component mineral supply to eliminate daily driving greenhouse gas emissions.

And if a cheap solar paint can reduce the grid impact of that then why not? Throw some research into that.

Yes, generally speaking rooftop solar will be more efficient, but I'm guessing rooftop solar and utility solar will have plenty of uses. There's STILL coal on the grid, and NatGas.

Hm. Perovskite spray-on solar cells... Hard to see how they avoid the perovskite degradation when it contacts air
