Coinhive works that way as well. I believe it is justified to call both a scam by themselves. Why? Ei incumbit probatio qui dicit, non qui negat (innocent until proven guilty).

The problem lies with our justice system though. If it were more efficient we'd have less things like self-censorship and self-moderation.

A L4 (not "senior") Google engineer can easily make 300k+ total compensation in Pittsburgh or Boulder. I don't think your pay is going to be competitive, because you're neglecting the largest component (equity grants).
Forgot about Bob! I grew up under the shadow of Microsoft but it's easy to forget about it entirely when I see nothing but Linux and Mac nowadays. Funny to remember what a cancer that company truly was/is.
Maybe the fact that students learn about how horrible it was as part of the curriculum during middle school? Also, the school in 1996 was nothing like the schools in the early 1900s, why would you use that as support?
When you start probing enough it quickly becomes practical/coding interview we all come to detest. Sure enough, that way you might not even need 30 minutes. But shop talk alone doesn't cut it.

Only if demand is relatively constant

The demand for classic opera recordings is constant. Year after year people will buy the 1966 recording of Tristan & Isolde at the Bayreuther Festspiele with Wolfgang Windgassen singing Tristan. These are reliable moneyspinners for the record companies, you'd expect to see initiatives to extend copyright.
OK, that makes sense... but what is a better solution?
I think /r/ChangeMyView has a really good approach to this sort of thing (I'm using them as an example a lot here, but it's because I think they really do run one of the highest-quality communities on the internet).

One of their core rules is that people posting there have to demonstrate that they're open to having their opinion changed - they can't use the post just to soapbox. There's a lot written about it here, it's been very well thought-out: https://www.reddit.com/r/changemyview/wiki/rules#wiki_rule_b

Yes it happens all the times from the newspapers. They select topics to cover or not (first biais) then cover it the want they want to fit their narratives (second level biais). In France, one of the most renowned newspaper (Le Monde) have a dedicated team (Les Décodeurs) to make posts about every politically sensitive topics. The official raison d'être of the team is to fight fake news, but the way they wrote is so fake-newish it becomes like an art performance.

"up to" usually implies a minimum, not a maximum.
Another cool Python DP hack is using @functools.lru_cache to perform the memoization (beware of the maxsize parameter though).
I was referring to a local basis. I.e. in most cases, plots of land of equal size on a given street are of similar value for similar purposes. My point is that people don't typically monopolise land to the extent that a prospective land buyer has one potential current owner they could deal with. Of course there are always exceptional cases where this breaks down.
The company also claims that it's not in danger of going bankrupt in the next few months, even though their auditor isn't sure they have enough money or current assets (i.e., membership fees) to survive through the end of June and raised serious concerns about their ability to survive as a going concern.
Yup, probably safest to just stay inside.
Carmack comedic skills seem as high as his engineering skills.

I would pay to see his happy deadpan delivery of that question to Steve Jobs and enjoy the pause after that.
And if you have all the time in the world to play that out --great. If you have limited savings like the vast majority of Americans -- time is your enemy, and eventually rent will come due. The company can survive for months, years without your labor and if they have to, they will simply purchase it or outsource it if need be.

You need that money more than they need you. There really are few exceptions to this rule -- AI being one of them.

Again I wish it wasn't like this, but it's the reality for the overwhelmingly majority of software developers in this country.
That's what the OEIS sequence they link to says. I hadn't realized that it makes such a beautiful pattern!
I don't understand this hate for whiteboards,

What's not to hate?

* unless both the board and markers are of very high quality, the boards tend to stain over time

* as do your fingers

* and the markers dry up, and the erasers get less useful as well (if they're available at all)

* you have to erase other people's crap (or wonder / ask if it's worth saving) first

* the dizziness that results having to turn back and forth between the board and your audience (that is if you don't end up simply talking into the whiteboard most of the time)

* and from stooping to pick up the pens / erasers / pen caps all the time

* and all of this, mixed with all those indelible memories of crappy interview experiences

I'll take pen and paper any day

which are a cross-industry cross-profession standard

Along with horrible interview experiences unfortunately.
Yet it is a fact. Not only do trolls seek to degrade and destroy freedom and democracy, they defend a bunch of corrupt morons who's only real ability is to either steal or exploit their own people.
Arduino Introduces New IoT and Professional Products at Maker Faire #MFBA2018
This one still stings, even though it was years ago. I built and ran a mobile sports news application, we amassed millions of users and were written up in several publications.

One day our AdSense account was disabled, no warning, no nothing. We had never resorted to a single 'trick' or 'hack'. Nobody at Google could even tell us what exactly we were supposedly accused of.

After months of escalation, the final word was "we cannot tell you what you have allegedly done, we will not re-instate your account, you may not appeal any further".
But in this case this is not even a business. It is a zero-revenue open-source project. It seems to me that only very well-funded charities are allowed to run web services now.

P.S. I sincerely hope my country gets out of this ASAP.
We will be happy with "it's a really pretty visualization of the primes" or "it's an improvement on the Ulam Spiral." But if it has more value than that (not sure.. but possibly there is some link in this that might be useful) then that's great too.

> Many academics, and most journalists and activists, claim that these so-called 50c party posts vociferously argue for the government’s side in political and policy debates. As we show, this is also true of most posts openly accused on social media of being 50c.

I am not a native speaker. I can't parse that sentence :/.

Why is this `also` true ? In addition to what ? Wouldn't it follow that posts arguing in favour of the government's side are tagged as `50c` since `50c` seems to be defined by being `pro government` ?

And then:

> [..] we show that the Chinese regime’s strategy is to avoid arguing with skeptics of the party and the government, and to not even discuss controversial issues.

If I ignore the `also` word in the first quote it all makes sense.
I agree with a sibling comment, you put together a good observation about how the posts get down voted and eventually getting out of the first page every time, but I think you should edit the last comment about his Xi Jinping's Wife.

> Otherwise you’d end up like the MD who’ve “rediscovered” numerical integration (the trapezoid method) and got it published in the journal of diabetes or whatever.

This was shocking because calculus is a required subject in American high schools, and this American doctor presumably went to American high school, not because the doctor didn't check in with mathematicians. Frankly, it would be equally shocking if the doctor had asked a mathematician if integration were a thing, because presumably a doctor is an educated member of society.
Maybe its an off-hours tactic?
I'd like to see the triangle fractal as a starting state for Conways "Game of Life".
The drawing is incorrect.

More specifically, it’s a drawing of OEIS A054521 (black if gcd(row, col) == 1, red otherwise), not of the parallax compressed primes. The two drawings do not match as claimed. The first place where they differ is row 9, column 1, which is drawn as black even though none of 217, 226, 235, 244, 253, 262 are prime.

It’s clear that gcd(row, col) == 1 is a necessary condition for there to be any primes in that cell (which consists of the numbers col + 3row² − 3row, col + 3row² − 2row, col + 3row² − row, col + 3row², col + 3row² + row, col + 3row² + 2row), but it’s not sufficient. There’s no way it could be sufficient, because there are only constantly many (six) numbers tested in every cell, but the asymptotic density of the primes goes to 0 and the asymptotic density of A054521 goes to 6/π².

It wasn't exactly clear to me when I read the article, so here's my explanation:

- take a line of integers, color them black if prime, red otherwise

- hexagonally arrange them in a spiral (similar to Ulam's spiral)

- cut the hexagon into six equilateral triangles

- overlap the triangles (rotate where necessary)

- if any pixels are black, color the whole thing black, if none are black, color it red

- interesting pattern arises

- interesting pattern already exists as per http://oeis.org/A054521

Edit: They may be packing more than 6 numbers into a pixel, looks like 75. Unsure how that would look visually, but you extend the above to use 75 or any other number. Unsure why 75 was chosen, maybe it's the only interesting one?
Hah! Yes exactly! Only I've never seen that happen ;-)
Do not cede control of an important aspect of your business to a third party^. In the case of app store distribution you find yourself in a principal-agent problem[0]. The agent in this case are the FAANG's of the world who are interested in having a wide array of quality third party apps available at little to no cost for their customers. You as the software developer want to extract as much utility[1] as you can out of the users of your software as possible. These goals are often at odds and since you are not in control of the decision making process you will lose. Some may make it rich, but the vast majority are set up for failure.

> Whenver there is any negative story about china, the downvotes happen immediately and "defends of the honor of china" pop up magically throwing dirt everywhere.

Maybe a little, but the main thing I see in stories like that is dozens of comments that that derail the comments into a "the US is just as bad!" flame-war, and kill discussion of the negative story.

It's really effective, because Western users are often ignorant of China and/or indifferent to it, but will happily jump into a flame-war about Western countries when presented with the bait.
Why is this downvoted? All governments do propaganda, this is a well known fact.

One particular interesting thing about this particular case is the scale and the focus, but do we really think other governments don't try? Even companies astroturf.
Obviously, but I was specifically referring to the typical algorithm oriented whiteboard questions found at major tech company interviews. Working a real world problem on a whiteboard I see no issue with.
Their picture is correct, but only because they are doing something more ridiculous than this. Every one of the squares in their picture represents 75 numbers, not 5 numbers.
From the 'About' page:

> Shoes 4 is a total re-write of Shoes. It's being done in JRuby with best practices. It re-implements the original Shoes 3 definition of Shoes in a pure Ruby friendly way whereas Shoes 3.x is more difficult for Rubyists to modify since it has C and Objective-C components and a build process that is less than easy to understand. Shoes 3.2 also has hardware costs and web hosting costs which makes if difficult for many developers to duplicate.
> "up to" usually implies a minimum, not a maximum.

“Up to” literally means a maximum.
Looks like the theory of evolution needs modifications due to epigenetics.
The thing is Ebola is evolved to have a stable impact on its host population, which is the common fruit bat.

We're just collateral damage.

So mutating for airborne transmission among humans is just not on the evolutionary agenda here.
Yes, Apple's graphic engineer and John probably knew what they were talking about, but I suspect that Jobs did.

It seems like based on that vague description, John wasn't necessarily arguing against his own interest and Apple engineers might have had to consider constraints that neither Steve or John was familiar with. Take for instance Steve's response to John's disliking for the iMac mouse -- in this case, Steve quoted "every study" that there were usability issues with first-time users.
But on the topics of OpenGL security, his trigger word, it seems, was "ideal."

Speaking as someone who finds DP problems easy, I'd not figure it out from this approach. The way that I'd think about and tackle it in an interview is this:

1. Write a recursive solution.

2. Memoize.

If you can solve it this way, then you have a DP problem. Of course this forces you into the top down (aka recursive) approach. But in an interview, "easier to reason about" is all that matters.

Also the tradeoffs in section 5 has a mistake. Memory can and frequently does go either way. Top down can let you recognize which states you never need to think through. But a bottom up (aka iterative) approach can let you discard memory after finishing an iteration. The memory savings from that can be considerable.

Technically yes, however it would be strictly worse than even a simple Sieve of Eratosthenes in accuracy, memory footprint, and speed.

Attempting to automatically discover proofs that constrain the prime number search space would be more likely to be useful in that domain.
The methods are interesting. It is worth noting however that it's not the any gov't wouldn't want to do this, or even doesn't.
Kind of makes you wonder how many of these operatives on here on HN.

There are certainly blocs of people who downvote certain topics en masse.
The HN moderating skew on anything regarding China is palpable. Anecdotal, but I’ve witnessed it every single time I participated (both ways). And I systematically see posts buried which otherwise would not have been.

It’s becoming a nuisance, which is fine. But I fear what will happen if the trend continues. It may very well end up suffocating thoughtful discussion about China and their policies. Which, ironically, would make it all the more important to have those :)

I find myself wondering if it’s astroturfing or blind nationalism.

(I agree the comment about his wife is in poor taste, by the way :/ I would support an amendment to your post, but I guess that’s your call.)

> the way Google and other companies use whiteboards is an epic fail.

They are optimizing completely different metrics than you do. They want crème de la crème developers that are perfectly trained not to think about certain classes of problems and waste time there but instantly come with acceptable answers, immediately recognizing the structure of the problem and having the ability to faultlessly transform it into a piece of code without a debugger. It allows the training from the best universities to shine.

The problem is when everybody starts doing the same, but without the prestige, salary, equity and lifestyle that Google provides.
It's okay: We all did.
Google, and yes, and unfortunately every interviewer is different, as all the bad experiences people post about can attest to.
Oracle did that to me. Twice.
We have a white noise generator that uses a fan inside to make the sound ;-). Makes far more pleasant white noise than anything with a speaker, in my experience.
As mentioned, the license is a factor, but there are a couple of other things I wanted to get done first as well. I feel that it's pretty important to have good documentation available immediately about how to get a dev version running, how things work, how to contribute, and so on. I don't want to just dump a pile of code out by itself, that's a bad experience for potential contributors.

It won't be long until it's open-sourced - a week or two at most. Before today, the site hasn't had very many users at all, and it's definitely not something I'm going to be keeping hidden/closed while I continue to develop.
I agree as well. Maybe she's uneducated and unintelligent, I don't know anything about her, but there are more polite ways of saying that and it distracts from the overall point.

It isn't clear what FDA could actually do in these cases

What most of the companies are doing, at the least the ones with "YES" in the "Does the product have a REMS with ETASU Impacting Distribution?" column is conveniently interpreting the law to block generics.

ETASU is "Elements to assure safe use". It's a part of the FDA's REMS (Risk evaluation and mitigation strategy). Certain drug have safety risks where the FDA has asked manufacturers to go above and beyond making it "prescription only".

REMS can include additional documentation and certification so that doctors prove they understand the risks. It can also include additional documentation for patients. The most strict REMS forces companies to restrict access by limiting the number of pharmacies who can dispense the product and blocking prescriptions where the terms of the REMs haven't been met.

It's that last part where the companies are taking a self-serving view of the law. Normally generic companies can request a sample of a branded product (to develop a generic) and the branded company must provide it. With these drugs, the branded company says "but there is no patient! They haven't filled out the forms! We'll get in trouble with the FDA if we do it!"

As a result, the FDA has come out a number of times and said "No, providing a sample to a generic company is not a violation of the REMS regulations."

This is an attempt to shame the companies into providing samples.

The most direct way to fix this is for Congress to tweak the generic drug laws and make it clear not providing a sample, even for REMS drugs is a violation and they can be penalized.
Now it is working!
I agree on the sophistication part but I think you are missing out on resources used on development of this.

the responsible party(ies) did not access to resources , man power or infra at google or even at an enterprise scale.
Sounds very Markov-chain like, doesn’t it? But I think it’s just written in an annoying way: sentences that seem short, choppy, and cut off, with very little context to string them together.
If you're interested in someones coding prowess and process, review something they have written with them. It's far more effective than commanding some nervous candidate to get in front of a group of people and start writing code on a wall.
> The GDPR gets so much hate

Hate? Try to think of it from a business in the US perspective that wants to know why they have to (for lack of a better way to put it) bogu to an entity that does not represent them in any way. And the fact that you might sell something or service customers in Europe does not mean you should have to answer to any rules that they setup either. Should the town that I live in and operate a web site out of be able to have rules in place and then go after citizens in the EU for not abiding by them?

And actually it's one step further since many of the procedures and rules are being taken broadly and universally even against entities (businesses and us persons) that aren't even covered by the GDPR.

And no it's not like 'oh if you want to sell a car in Europe you need to certify this and that' that is not the same thing. Why? Well for one thing the golden rule. If you want that car allowed through the port you need to do what they tell you to do or they have a right to not allow it on their land. In this case their citizens are utilizing US websites and therefore it's on them to determine if they feel the service or product they are getting is fit.

I am referring to US businesses that don't have an office or physical presence in Europe. To those that do the 'golden rule' applies.
The method is different perhaps, which is interesting. I think that is an interesting point of discussion.

In terms of intent or morality or whatever, it's just a different method for propaganda. I don't see this as a different category for what other governments have done in the past.
Very interesting. I always get that uncanny valley feeling even on Hacker News, especially when the comments concern China. This would explain a lot.
On HN it's not unique to China. Anything negative about India is downvoted into oblivion. You can almost time it to the rising of the sun in India Standard Time.

I'm not saying that it's being orchestrated by the Indian government, but it does happen.
It might be a fact (I don't know), but certainly it detracts from your point. I think you should edit out the stuff about her.
That's a fools gold rush ;)
