I'm not so sure. If a property that is held in common is going to be sold, perhaps a good faith effort to contact the property owners requires a bit more effort, regardless of whether the amount due is small. The sale price was $90k.
The biggest reason for these delays I've found over the years it the signaling system and headway spacing.

Blocks on a railway system are designed to provide enough space and warning so that trains do not crash into each other. However, when you use line side signals and CTC (Centralized Train Control) to dispatch them, you end up with a set of rules that create spaces for occupancy that can easily be longer than the trains themselves.

In the NYC subway, speaking as an observer as opposed to an insider, the signaling and dispatching requires certain distances between trains and headways (time between trains) to provide safety of 2-4 minutes. However, this results in the cascading delays as one train that dwells too long in a platform can have a stacking effect on trains behind.

For example, if your minimum block distance is 1000 feet, and a max length train is 500 feet, a stack of five trains waiting to enter a station would actually occupy 5,000 feet of track. This could stretch to previous stations along the line.

The best solution would be dynamic blocks and cab signals, where the system itself defines spaces occupied by trains and only allows a train into a space where it can occupy safely, but also can make the distances dynamic based on conditions. Cab signals would be required as you can't have dynamic blocks with line side signals.

However, to do this requires a massive investment in new equipment both line side and on the trains that would take years to implement, along with a massive amount of painful work that would cause even more issues while it is being set up.

Sadly, running more trains probably won't cut it as the system literally cannot handle more safely.
Not keeping a tool box around the house very rarely means not having access to tools. Tools are commonly borrowed/shared amongst friends, family, neighbors, co-workers, borrowed from work, co-ops[1], makerspaces, or rented[2].

I love the Erlang way of dealing with this:

% Problem #2

% Each new term in the Fibonacci sequence is generated by
% adding the previous two terms. By starting with 1 and 2,
% the first 10 terms will be:

% 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

% By considering the terms in the Fibonacci sequence whose
% values do not exceed four million, find the sum of the
% even-valued terms.

fibsum(_N,M,L) when M >= L -> 0;
fibsum(N,M,L) when M rem 2 =:= 0 -> M + fibsum(M, N + M, L);
fibsum(N,M,L) when M rem 2 =:= 1 -> fibsum(M, N + M, L).

problem_2(L) -> fibsum(1, 2, L) .

problem_2_test() -> ?assert(problem_2(100) =:= 44).

problem_2() -> problem_2(4000000) .

Kite Power Systems (http://www.kitepowersystems.com/) came to give a talk to the Institute of Physics in Cambridge earlier this year. They use a dual kite system where one kite is generating whilst the second is being pulled back in, and having demonstrated a 40kW system are about to deploy a 500kW system.

I paid off most of my loans the first year after graduating, but held onto the lowest interest one with minimum payments despite having been able to pay the whole thing off for five years because I expect the same - the week after I pay the damn thing off is the week unconditional loan forgiveness happens and I wasted all my money.
> Redundant information. The latter follows from the former.

It's a blog post, not a paper. If I give you a brand new operator ^ that takes an arbitrary object a and another object b and tell you that it has anti-commutativity, it's not a given that a ^ a = 0. So it's useful to highlight that this IS the case when a and b are the vectors of GA, for intuition's sake. a = -a iff a is the zero vector. What if our objects are rotations or something though? R = -R does not imply R = the zero rotation.

Anyone who's interested in more ideas along these lines should look at Tyler Cowen's list of how to be less complacent: http://tylercowen.com/complacent-class-quiz/
The wikipedia article doesn't mention it, but just like Tom Sachs spent time at Gehry's shop and adopted this term and practice; so did Casey Neistat spent time at Sachs' shop, where he also adopted it (and probably made it more well known than ever before). If you've seen Casey's videos or pictures of his famous NY studio; this is where it all came from.
I love the Prius but it's a hybrid, not a full EV. Now when we've seen that full EVs can have long range why would we bother with internal combustion engines at all?
He was more of an asphalt dictator who barely tolerated mass transit.

But I agree with your point.
At one point calculators were rows of women performing rote calculations. Early programming was similarly dull/full of detailed work that went through successive waves of abstraction.

This is (also) a sexist stereotype, but maybe just maybe women are drawn to detailed work (say, needlepoint knitting, picking berries) while men are drawn to broad, imprecise work (such as selling insurance policies or chasing antelope). Maybe women are better at punching BCD numerical integrators for problems brought down from Feynman and Fermi, while men like coming up with a whole new language that compiles to PHP.

"Women" and "men" meant as generalities and not in the least implying that within-group variation can't be larger than between-groups variation.
Why do you assume they won't be putting time and effort into maintaining the property and making improvements?

In fact, they already did, by paying the debts of the property.
As someone with difficulty in crowded places I would have preferred less crowded trains over anything. Many times I had to wait until the evening rush was over before I could get on the 1 train home - the morning rush I had no choice.
I don't see anyone commenting in zealous joy when it happens to poor people. So at least there's that.

Either its okay for everyone, or okay for no one. It's hypocritical otherwise, and gives us little moral footing to stand on.

Sure, maybe its true rich people usually do this to poor people. But it's different rich people. Being happy because some rich people are getting screwed over because other rich people are assholes is incredibly stupid.

Yep:

"Nevertheless, buyers of commercial property have found a way to avoid this reassessment. Instead of buying the property, they buy the legal entity that owns the property. Under rules set by the Board of Equalization, a change in ownership of such an entity doesn't trigger a new assessment of its properties unless more than 50% of the entity is acquired by a single person or business."

"[Michael] Dell agreed to buy the entity that owns the Fairmont Miramar for $200 million in 2006. But after the deal was struck, Dell rewrote the contract, bringing in his wife and two investment advisors as partners. Because none of them held more than a 49% interest in the entity that owned the hotel, the hotel kept its assessment from 1999"

Not so. The material in "Unfinished Tales" was known since at least immediately after Tolkien's death, but publication was delayed for years until "The Silmarillion" had been published and allowed to soak up bestseller attention for a while first. The same is true of "The Tale of Beren and Lúthien", which Christopher Tolkien was aware of all those years since his father's death, but it was decided to save them for a rainy day.

> This is because a recursive sub-function never solves the exact same problem as the original function, but always a simpler version of an original problem.

This isn't always true. There are plenty of recursive functions whose purpose is merely to climb until a condition is met that there are no more rungs in the ladder.

Recursion is difficult because it isn't just taught, it is mythologized as the potentially infinite source of a one's love for programming. If teachers similarly mythologized the "switch" statement I'm sure they could confuse the topic of conditionals just as easily.
This was my thought as well. When I first heard about this weekend, this was the first site I went to see what people were saying.

The only I could find any of the threads was by doing a google search for "google manifesto" & "hacker news".

The debate in a few of the threads were quite diplomatic. However, the social media universe reacted as expected. Liberals condemned the author for the typical "racist, bigot, homophobe" diatribe while the conservatives argument was, "Guy speaks out about not being able to speak out, and then gets carpet bombed by SJW's back into silence."

It really sucks this is where the country is. When EVERY topic is off limits and you cannot hold a rational discourse over something, it should be clear evidence the decline of Western Civilization is at hand.
It's a long way from even an 8080. The 8080 had a couple thousand gates and ran at 2+MHz. At 50 gates per second, this would run an 8080 at maybe 20 millihertz.
This may not be 100% accurate in nomenclature, but it gets the point across. Laminar flow is uniform and very easy to model mathematically, hence the reference to its "clean-ness" (e.g. clean [simple yet functional] design, clean [elegant] math proofs, etc). Its opposite: turbulence. laminar:turbulent::clean:dirty. You get turbulence/wake when there's something upstream of you disturbing the flow patterns. Air has less potential energy in it once it has been disturbed (the random motion of turbulence detracts from it's ability to generate pressure differences via flow manipulation). Riding in dirty air happens when the rich man's yacht in front of you sails upwind of your own personal rich-mans-yacht. Your vessel can still sail, but will sail a little bit slower, due to there being less available energy in the wind for you to tap into. This becomes a problem w/ turbines for obvious reasons (ask yourself why they don't just put multiple turbines all on a spoke for cost-of-installation savings, or even why they always seem to choose 3-bladed turbines [a very cool/interesting mathematical optimization problem!]).
> I generally got the impression that the ones that really struggled were the ones that fundamentally didn't understand how function calls and returning values truly worked.

You're probably right.

I don't think in the entire time I was in school, we were shown a debugger and how to read a stack trace or step through code. In one of my classes, we might have glossed over it for a couple minutes, but generally there was very little real debugging shown. It was always "Oh, we didn't get the expected result, let's look harder at the code we've entered." My school may have offered a class on debuggers as an elective or maybe a Masters level class.

Really though, using a debugger, even if it's just the one in Visual Studio, should be included in the first-year classes. By the end of your first year, you should be able to know what a stack trace is and what it's telling you.
> “Do your cars have seatbelts?”

Definitely not a clear question. What if it only ha seatbelts in front but not back? What if they comply with EU regulations but not California regulations, or vice versa?

> “Does your food contain salt?”

Even less clear. Do you know about California prop 65? It is a fail of epic proportions, because "contain" may mean "has enough to cause an effect on an average human", "has enough to cause an effect on a human with extremely rare condition that makes him sensitive to salt orders of magnitude higher than a regular human" or "has enough to be detectable by the most sensitive detector created by modern science". That's even without getting into the weeds about how common table salt is not just sodium chloride, and sodium chloride may be present without adding table salt (many organisms have it so if you eat them you eat salt). Not try to pack it into 140 characters in a way that a hostile journalist can't make a scoop out of it. Good luck.

He was the opposite of mass transit though. One can argue that if he had wielded his powers for good, that NYC would be much better off today.
I have some pretty ironclad faith in the scientific method, but far less so in the scientific establishment. Don't get me wrong, I don't think scientists are doing a bad job and don't think I could do any better as an individual if I were a scientist. But most people's understanding of "science" goes through tons of filters that hurt its quality: statistical illiteracy among scientists, messed-up incentives in the publishing process, political pressure within research, skew in what the media is incentivized to cover, the obscene amount of dishonesty and incompetence in science reporting, etc etc.

I've yet to meet someone with such faith in science whose understanding of what "science" is goes beyond pop-science articles and things that all of their friends "know" are scientific fact.
Yes it is long due for a major overhaul. Fortunately with new tech it is finally possible to do something about it. Imagine a large scale union of sex workers with strong protection. They will be able to demand safer working conditions and join together to leverage power over abusive clients. They can coordinate and accurately judge demand. The company can then do marketing and logistics on their behalf. It would also enable women that are not as entrepreneurial but do not want to give up all their personal control to a local representative.

Nokia was twice as big as Apple.

Nokia's sales for fiscal 2006 were close to $50 billion with $5 billion in profit (in 2006 Euro/Dollar terms). For fiscal 2007, their sales jumped to closer to $60 billion (for 2008 as well).

Apple's sales for fiscal 2006 were $19.3 billion. Apple didn't pass Nokia in size until the end of 2010; as Nokia began the drop that saw 40% of their sales disappear in just four years.
It is valid criticism. The rule is a rule of thumb, so isn't like a law of physics. The amount of internationalization would be relatively similar over short periods of time, so is an OK measure cf 10-20 years ago, but yes has problems comparing over a century.

Other similar issues are the amount of private ownership of US companies (that aren't included in Total Market Cap), and also foreign ownership of US companies which is higher than it used to be (I think).
No, it just means that ones that meet the current requirements are not available in sufficient quantity.

There were quite a few Medium posts as well. But no, I completely agree with you.

And I'm not just talking about being able to "Google it". If I use Google or a general search engine then I have to wade through who knows how many links of ambiguous quality and/or bias.

I find the tone of absolute certainty off-putting.

> The asteroid is falling towards Earth on a fixed trajectory, but the Earth itself is spinning beneath it, one revolution every 24 hours. This corresponds to around 1,000 miles an hour in the region of interest. So arriving ten minutes earlier or later would have placed the impact some 150 miles further to the East or West. And if this had happened, the asteroid would have missed the shallow gypsum-rich continental shelf, and encountered only the oceans on either side. No gypsum in the impact zone, no sulphuric acid haze, no long deep winter. While things might have been pretty rough for anything living within a couple of thousand miles or so, the rest of the world would hardly have noticed.

> ...

> And if the meteorite had arrived ten minutes earlier, or ten minutes later, it would still no doubt have inflicted devastation, but the dinosaurs would still be here and you wouldn't.

While the specific hypothesis about the chemistry of the impact zone is very cool - and drilling and analysis a very compelling project - I think that the credibility of the conclusion is clouded a bit by the idea that the reader is supposed to accept with certainty that the events unfolded exactly as the author describes to within a 10-minute window.

According to the article they're basing it on job postings and stack overflow questions. Doesn't seem like a great methodology but I can't think of a better one.
I studied engineering and there was very few women (<20%) in my class. You can't blame companies for having a similar hiring ratio. And the recruitment of the college I went through ("grandes ecoles" in France) is purely based on a math+physics competitive exam, so there is very little selection bias in the first place. So I am not convinced discrimination is the key to explain gender imbalance in engineering jobs.

Name your variables.
The sentence before the ones you quoted is:

> At issue is the publication of news that is false or misleading.

Initially in the election, "fake news" was a term primarily used to refer to stories and sites that were complete fabrications, created to make money from ads and for political ends. Use of the term quickly expanded to include more long-standing practitioners of distortion, like Breitbart.

The whole point of this article is that "fake news" can have real consequences so the supposed successes of Steve Bannon has nothing to do with the veracity of the publications headlines and stories.

Here's just one example of a fake Breitbart headline:

>Condemned as "fake news" by some media pundits, the Breitbart article was headlined: “Revealed: 1,000-man mob attack police, set Germany’s oldest church alight on New Year’s Eve.” However, according to local journalists, there was no mob and the St Reinold Church – which is not Germany’s oldest – did not catch fire. Local police said the night was “rather average to quiet” and the number of incidents in Dortmund on New Year’s Eve had decreased to 185, down from 421 in 2015/16. The brief fire on scaffold netting near the church was reportedly caused accidently by a wayward firework.

"Lucky Jim" by Kingsley Amis should be essential reading for grad students.

This author's story sounds pretty familiar, but without the comedic revenge denouement.
A couple of the suggested theories are that the tools designed to select applicants changed to focus more on logical aptitude tests, and on finding the right "culture fit."

Another argument which I have seen is that the marketing changed to focus more on men and boys, and so the narrative changed to "personal computers are a thing for boys". Here's an Apple ad from 1985 often used to support that argument:

https://www.youtube.com/watch?v=rxNjx_VWJ8U

Personally, I find both of these arguments plausible. You don't have to look too hard to find engineers who don't think tech hiring works very well, and yes, that advert does exclusively talk about boys.

I don't think "sexism" caused the current imbalance any more than I think Google's algorithm is "racist" when it shows racially objectionable content.

I think it's a case of a rule being arbitrarily applied and having an unintended and unforeseen consequence over the far future. And if that's the case then its a legitimate and noble endeavour to try to fix "tech hiring" so that it does find the best person for the job irrespective of gender.
I don't think telling people who find a subject difficult that it is easy is very convincing.

Recursion seems fairly straightforward to me if you think about it in terms of how it's typically implemented (the stack and jumps), but that's not quite the mathematical way of thinking about it, I suppose.
