Reread my answer for orange, I'm sure it is correct. To say it a different way: a circle X is coloured orange if X is touching a circle Y, and both X and Y also touch circle Z. Y and Z can either be small circles or the main outer circle.

The colours are about constraints. Orange is a locked constraint between 3 circles (inner and outer included).

If you think about it, N=2 is the only solution that the circles are constrained to touch in two places (and N=1 is weird because it touches in infinite places).

At N=104, the blue circles are surely a drawing fault, they are actually unconstrained and should be magenta. Shown by fact that those blue circles have a dot in the middle (not touching), but a neighbour circle has a line pointing to the blue circle (touching), which is contradictory.
How is that relevant? Australian wages are high because of a long period of unionised action demanding better wages and working conditions in the 20th century. It's tangential to having a lot of natural resources.

Norwegian wages are good too, Venezuelan and Saudi wages are terrible.

We squandered all our mineral wealth on nonsense, have huge respect for what the Norwegians have achieved with their fund.

That's a clear overstatement for which I can't find any evidence.

Contracting HIV with unprotected sex is difficult (1/1000 for vaginal sex and insertive anal sex, 1/71 for receiving anal sex - all numbers for unprotected sex) [1], breaking a condom is also difficult (4% cases in anal sex between gay men - which is the higher number [2]). Meaning that contracting HIV while wearing a condom, is extremely difficult (0.05% in the worst hypothesis).

It's up to you then, to prove that PrEP is more efficient than 99.95% of times (while still disregarding that unlike condoms, PrEP doesn't protect you in any way from other STDs... yes, those STDs that people not using condoms and that think they are entitled to have other tax/insurance payers providing PrEP for them, are spreading around).

I’m working daily on a pretty large, gnarly, legacy monolith, and consequently been thinking a lot about approaches to refactoring when I came across a (ruby) library called Suture [1].

It allows you to perform black-box testing, recording and replaying test data (gathered from production).

From there you can refactor your code and even have the library run both new/old codepaths in production, raising errors if there is a mismatch.

To your point about constant rewrites, I think using a library like this while continuously refactoring existing code is a pretty exciting idea.

Too bad I need a Java version (maybe a good idea for a side-project).

Yeah, I don't agree. How does one go about assessing the validity of any given prior a priori? All priors are based on some sort of logical reasoning based on past experience, but much of the time when investigating something novel there's no guarantee that past experience is a good predictor. Often we don't even know to what degree we can or cannot rely on past experience.

I just don't buy that there's something magically more "mathy" about just conjuring assumptions you want to test.
You don't feel upset about how they were, in my opinion, defrauding you and the driver of the tip money? After I learned about what they were doing with tips I decided not to use them again, and considering how much competition there is I really haven't lost anything of value.

This isn't meant to be a triggering comment. I'm genuinely curious to learn about other people's reactions to DoorDash's former tipping system.
If nothing else in your life gave you the idea to buy something but an advertisement did, it's not your idea to buy the thing. I needed a new chair because the one I used to have gave me back pain. I went on Amazon to look for a replacement chair, and because I use an ad-blocker (uBlock Origin), I didn't see any advertisements for chairs (whether there are other features of Amazon that could count as advertising, like the Amazon's Choice branding is, sure, debatable but also besides the point). Instead, I saw a list of chairs with information about them. I looked through the list and found the one I thought would best suit me and bought it. Why did I buy it? Because I felt I needed it since I was concerned that my old chair might have caused back problems if I kept using it.

Since I bought the chair on Amazon, when I don't have an ad-blocker on, like on other people's computers, I can see Amazon showing me advertisements for other chairs. Why? They are trying to convince me, because I showed a willingness to buy chairs, that I need more chairs. There are all sorts of flashy listings showing off the neat gimmicks their chairs are capable of, all to convince customers like me that what we have isn't good enough.

They can't make money if they solved people's problems, so either they design things to break (like planned obsolescence) or they psychologically manipulate people into thinking they have problems they don't have and sell them the solution (InfoWars is this taken to the extreme).

There is a difference between putting information out there for people who want to find it and blasting information at them to get in someone's head and convince them they need to do something for your own benefit.
When you visit somewhere what do you enjoy seeing or doing? Nature? History? Culture? People (as in people-watching)? Local cuisines? Unique activities? I wouldn't recommend Yoyogi Park on a Sunday afternoon for people who aren't that into people watching and don't care to see the Rockabillies dancing. I equally wouldn't recommend any particular temple or shrine to a person who's attitude towards them is "Seen one, seen them all." I have a particular soft spot for Inari shrines and go out quite of my way to visit many of the smaller/local ones.

I also second Jack's recommendation of Nikko. It was one of my favorite places I visited. Lake Chūzenji was beautiful in the spring when I went.

28 with higher net margins and 65 with lower net margins.

As I said, not great, not terrible. They're doing just fine, but they are also far from abusing their position. An industry abusing its position would be one with higher net margins than almost all other industries. The fact that 30% of industries have better net margins suggests that this industry is far from being abusive in its pursuit of profit while improving people's quality of life.

TRUE LIFE TESTIMONY OF HOW I GOT RID OF CANCER THROUGH DR, ALABI HERBAL MEDICINE.

Hello everyone am Sharon from Australia, i am here to give a testimony of how i was cured from CANCER i never thought Dr.ALABI MOHAMMED can cure my cancer, until i was cured with his herbal medicine, I have tried almost everything but i couldn’t find any solution on my disease, i have spend a lot of money to buy CANCER drugs from hospital, and several medications but to no avail, until one day i was browsing on the Internet just like you are doing now when i came across a great post of mrs Diana from USA who truly said that she was diagnose with CANCER and was cured by Dr ALABI that very week through the help of his herbal medicine, so i really wonder why people called him the great healer, i never knew it was all because of the great and perfect work that he has been doing, so i quickly contacted him, and he ask me some few questions and he said a thing i will never forget that anyone who contacted him always get his or her healing in just three weeks, so i was amazed when i heard that from him, so i did all he ask me to do and he prepare the herbal medicine and send it to me through UPS courier service, and i received the herbal medicine after 3days,and he instructed me on how to use the herbal medicine, just 3 weeks of usage i was healed from cancer which he said i will be healed from, so after 3 weeks all the strength that left me before rush back and i become very strong and healthy, this disease almost kill me, so i went to the hospital for test and the doctor said i am negative, i was very happy about the healing of Dr.ALABI MOHAMMED who is from the ancient part of Africa, thank you sir for your great work.

I think there may be a difference of degree here. Combine an interest based monetary system with a high rate of deflation and you will have the fastest most boring game of Monopoly ever.
@ → A → array

$ → S → scalar

That's how I learned and remember them.

What makes that less obvious is when you work with references to arrays; the reference itself is a scalar, so it gets the scalar sigil. You can dereference it, though, by sticking an array sigil in front of it, thus telling the interpreter "hey, this is a scalar reference to an array".

In current Proof-of-work (PoW) blockchains, the more mining hardware you have, the more coins you get, and the more mining hardware you can buy. In this sense, the same exact monopolistic structure you mention exists in both PoW and Proof-of-stake (PoS) blockchains.

However, (PoS) is a lot less monopolistic than PoW for other reasons:

1. Massively reduced economies of scale. Pretty much all POW mining happens in mining farms for a reason: it's a lot cheaper, per unit of revenue, to move all your mining to one big warehouse. This makes it pretty much impossible for a normal person to contribute to PoW in any meaningful way -- good luck running a competitive mining farm out of your house. In PoS, however, 10x more coins will get you exactly 10x more rewards, and costs don't fall at all, leading to less economies of scale, and so less pressure towards a monopoly.

2. Ability for the protocol to apply punishments as well as rewards. In PoW, because the miners aren't tied to any address, there is no real mechanism for punishing them. In PoS, because the "mining power" (aka coins) is in the protocol, bad behavior can be punished. This has two benefits from the perspective of monopolistic market structure. First, it makes it so 51% attacks are costly in protocol. If evidence is shown that you 51% attacked, your coins can be "slashed," or taken away. Notably, in PoW, a 51% attack is free to the attacker if successful. Second, collective punishments can be applied to miners (validators in PoS language). This makes it so miners can be punished if they censor other miners -- again leading to less centralization/monopoly pressure.

Please do disagree (or make me clarify) with anything that seems stupid/unclear/incorrect in the above. I'd love to engage more!
It seems the statute disagrees with me, but it seems wrong to sue the retailer. Sort of like safe-harbor provisions for copyright violations. I don't think it's practical to expect retailers to vet the functionality of an item against active patents and then audit the wholesaler's patent license portfolio for compliance. More practical would be a takedown system where the patent holder could notify the retailer of infringement, and the wholesaler would have the opportunity to respond, again like how things are handled with copyright. (Not that the process there is without flaws)
I came here to post that very same thing. What a great resource that was!

They're not classes in source code. As an implementation detail, certain compilation strategies do generate them anyway.
they use invokedynamic instruction so a little more efficient than a class once jit'ed (for hotspot, not sure about the other jvms). there might be some cases where class generation is needed, but i don't think so
> How likely is it actually that out of the set of 116 people who look like you from your your state (which I see as basically a random sample of 116 people, unless you have a tendency to gravitate people who look like yourself toward yourself...), one of them was in the same area as you, at the same time that a crime was committed against you there?

That's going to depend a lot on how stringently you define "in the area" and "the time of the crime" as well as things like population density and demographics. For example, if the perpetrator is a particular race and so consequently are all the facial recognition matches, and the state's population has particular races concentrated in particular areas, expect that to affect the probability in a way that leads to more false positives all around, because it's then effectively the case that people with similar faces tend to live near each other.

But the really perfidious thing about all this is that it's not just facial recognition and cell phone matches. Suppose the chance of a random person out of a hundred with a similar face being in the same area is "only" 5%. That would be the case if there were around 500 people in the vicinity (not unusual in an urban area) in a state with a million people, and then around 5% of your convicted criminals would be innocent.

But we're not just checking faces and cell phones, we also check all kinds of things like internet history, family and work connections, financial and purchasing history, etc.

Then we come to find out that one of the facial recognition matches did a web search for Halloween masks in October of last year and the co-conspirators whose faces we don't have were wearing masks, and the same person has a low paying job, a fair amount of debt and a second cousin with a twenty year old conviction for marijuana possession, and the cousin's cell phone was in the vicinity of the crime.

It's a pile of circumstantial nonsense. It's all selection bias and dependent variables. Everybody searches for Halloween masks around Halloween. Each of your hundred odd facial recognition matches has a hundred odd family members, there were a few hundred people in the vicinity, you start multiplying numbers like that and you get coincidence matches. The random cousin who hangs out in the same areas as crimes are committed is not unlikely to have a checkered past.

But all the jury sees is a huge pile of evidence. Which gets bigger the more mass surveillance there is, independent of guilt or innocence, because more surveillance can uncover more coincidences. (And then they pick up your cousin and find drugs on him again, and suddenly he's testifying against you for a lesser sentence even though you haven't even seen him in five years.)
What separates them is the ridiculous amount of VC funding they took and have used on a combination of marketing and buying exclusives. Every actual experience I've had with DoorDash has been rather poor though, and they've gotten in trouble many times (they even got sued by In-N-Out a while back when they re-listed In-N-Out against their wishes using a knockoff logo to avoid trademark infringement). The only reason I ever use them is if I really want something that they have an exclusive on, and even that is rare (usually I'll eat somewhere else rather than order from DoorDash).
I think that "Gerrymandering is so rampant that you can make 24 of the 26 letters out of gerrymandered districts" still demonstrates their point.

While this was definitely not clear to the consumer, it ended up being a preferable model for the drivers as they would get a higher pay on most orders. Not saying that it should be that way, but saying they did that just to steal tips is not true. It was used to guarantee a minimum amount on orders that don't make sense financially.
> That courier was full of shit. You get paid regardless of customer status, and you also get paid per minute over a certain delay threshold. Sounds like you just got a bad actor.

I've never been a courier so I wouldn't know.
You gererate a hypothesis and then experimentally test that hypothesis, I don't see anything wrong there. How else would you evaluate new theories that go against convention? Maybe you are suggesting that he fudged the data or otherwise manipulated the experiment to get a desired result?

I recently read Carl Newport's "deep work". One of the points he made that struck home the most was that a leading indicator of success for most knowledge workers was the number of hours spent doing deep work. Ie - the number of hours spent doing uninterrupted work that makes use of your differentiated skills.

As a remote worker the thing I treasure most is the opportunity to organise my schedule to spend the majority of my time doing deep work. Frequently communicating and getting feedback on my work asychronously rather than constantly being interrupted and dragged into synchronous interactions as in an open plan office.

The thought of allowing anyone to contact me at any time, at the push of a button feels like a huge step back.

There are lots of challenges around communication in a remote company, however I don't think the solution is recreating an open office online.
