I really wanted to link to arXiv:1606.08481v1[0] because its a really fun paper as he walks through how he sets up the problem (even if he limits it to rank 3 real spaces, but its fun to think about how it could be represented in rank arbitrary-n real spaces and ways of computing such), but figured people might engage more with the discussion on his blog :P

He wrote a couple days ago:

"One possibility is that of a self-similar ansatz, which under suitable rescaled coordinates would become a steady-state solution of the Euler equations with an additional scaling correction to the velocity field. Such self-similar solutions cannot exist if the vorticity is sufficiently localised (basically because of energy conservation), and there are various results by Chae relaxing the localisation requirement, however as far as I know a self-similar solution that is slowly decaying in space has not yet been ruled out. As I remarked in the paper, I attempted to construct such a self-similar solution, but was not able to do so (particularly if one wanted to impose self-adjointness on the vector potential operator, as this together with self-similarity imposed a lot of constraints on the solution)."

And it made me think about how we can go about computing such, and since lately I've been kind of obsessed with the Jacobi-Davison algo, and how it uses the ritz method (to compute the ritz ansatz), could maybe fit here in meeting the conditions of self-adjointness on the vector potential operator without imposing constraints on the solution as it exists? In armadillio's svds[1], they embed their "vector potential operator" matrix X in larger dimensional sparse space reflected along its diagonal:

⎡	zeros(X.n_rows, X.n_rows)	X	⎤

⎣	X.t()	zeros(X.n_cols, X.n_cols)	⎦

And this has "worked" for other physical systems I computed things for (spacial beamforming with eeg), but this specific application and the care for the mathematical rigor needed to explore more thoughtfully is above my paygrade :P

Personally I think one of the main reasons US police don't hesitate to use deadly force is that they are not held accountable for it. In the UK it s a big deal when an officer uses his weapon, there are investigations etc. In the US, as we've seen in the last couple of years, there can be start to finish video evidence of an officer using deadly force completely unnecessarily and he/she gets away with it. If you start prosecuting officers for using deadly force without proper cause I'm sure use of it would drop pretty dramatically.
It doesn't need to be finished to be useful.
> but is in fact more useful as a positive role model to the enforcers.

On the other hand it can also some kind of proof of honesty and transparency. "Hey, I did that work alone, which is slightly odd, but hey at least I'm not hiding this fact."

I agree with haddr above. People should not be ashamed of using "I" instead of "we" when it's relevant.
What is you point ?

Still a lot of value in the parts that are finished, and while it is somewhat beside the point, it is much more finished than most similarly ambitious projects in the tutorial/learning domain. It even has a license that allows anyone that has the time, knowledge and will to extend it.
> and probably not nearly enough training

What makes you say that? As I understand it, the training is pretty rigorous.
>> "probably not nearly enough training"

Any evidence of this at all? Aren't UK officers that carry those kind of weapons specifically trained to use them?

>> "in London there is no shortage of cops wandering around with AR15s and MP7s"

Where? In airports maybe but it is very rare to see them on the streets. I don't know what area of London you're in but I can't remember the last time I saw one besides at a large public event.

Interesting - I would have guessed way more. The ones most visible to me (at airports) are always armed to the teeth.
Rather seems to be missing the point. In Australia, police carry guns. Unfortunately, there are police shootings but they are very rare and when it does occur there is a full and thorough investigation done. I don't think I've ever heard of a case in the last 15 years of anyone in the Australian police firing a gun at someone unless they were literally in imminent danger of serious violence from the one they were shooting at.

As an Australian citizen, whilst the police here aren't perfect, I also believe they aren't as trigger happy because, quite frankly, we don't carry guns on our person in Australia. This means that when police make a routine stop because of a broken tail-light they aren't as likely to feel like their life is in danger, and this almost certainly means they hesitate to fire their weapon unless they are really in danger. They are also aware that if they do discharge their weapon then there is a full investigation done. The investigations are quite thorough and actually normally very fair, but no police officer wants to be investigated really and all police officers know what a serious thing it is to fire their sidearm.

I don't expect any citizens of the U.S. to agree with me. But it occurs to me that as more people carry increasingly powerful weapons, the police have had to upgrade their own weaponry, body armour and tactics in response. From my vantage point here in Australia, it puzzles me why this isn't obvious: the more people who carry guns, the less likely law enforcement will try to negotiate and use minimal force.

From my perspective, America's gun culture is bizarre.
> Every force has access to them, and training is as much about de-escalation and negotiation as shooting.

Or just plain non-shooting solutions to the problem. When a person having some sort of psychotic break started smashing up a local games shop with a weapon, the local police made sure the staff were out, let the offender tire himself out breaking things, and then used pepper spray before arresting him.

I would be very surprised if the equivalent scenario in the US didn't involve shots being fired.
Why is that ? I've never used Ember, but it seems like the framework with the best tooling and backwards compatibility track record. Maybe I'm wrong, I don't know.
As someone on the spectrum I don't see it as a detriment. Despite a seemingly vast difference between a high-functioning engineer and a low-functioning child, the strategies for improving the quality of life are pretty much the same. Routine, sensory stuff, avoiding meltdowns, recognizing emotions, all that stuff - it's as real for a brilliant but eccentric programmer as it's real for a non-verbal kid with no particular talents.

Because in the end, it's about improving the quality of life.

I'm on the "eccentric" end of spectrum; for 27 years I've been told that nothing is wrong with me, that I'm just "too smart". I can tell you I was pretty close to joining the 27 club; the piling problems ended up being too much to handle. I came upon the description of Asperger's purely by accident; no mental health professional would even suspect it because I "seemed normal". Finally being able to understand why I'm losing my ability to speak once in a while or getting violent whenever overstimulated wasn't just a relief. It was a life-saver.

If I didn't realize it's ASD, ignorance and stereotypes could have killed me.

PS. Yes, some people will claim they are "a little bit autistic" out of ignorance or attention seeking. Others will lump clinical cases with weirdos. Both don't change the validity of a proper diagnosis.
> An obsessive personality can lead to an individual working 80 hour weeks - not by choice, but by default. They literally don't know any better and are not necessarily competent to make a conscious decision not to this.

It gets even worse. Once someone with Asperger's "clicks" into a specific routine, it becomes a pretty challenging endeavor to change it without some external influence. Same with bad eating/sleeping habits. I'm currently in the "works overtime out of habits" phase and it's extremely hard to snap out of it.

In the UK there may well be investigations but the end result is the same.
Airport is MOD police, you have to be an Armed Responce officer in the UK to carry guns which is a specific qualification that requires training.

That said when armed response is called for they do not show up with handguns but with MP5's and since 2009 or so with full auto M4's.

Problem with philosophy is that it views all anthropocentric. On the other hand, we are beyond anthropocentrism in modern physics in the sense that sensorial / bodily experience (our way to interact with the outer world) doesn't help any more and thinking / mind abstraction (our special way to represent the outer world) is unprovable because technologies and tools are not there yet. More than philosophy, it is literature to stand up when we need a change of paradigm, in particular science fiction: minds trying to carve skewed views of the universe starting from non-mainstream philosophy. Suffice to say, it will be many more misses than hits but gold is there.

Seawater becomes drinking water of the future
The article treats these police forces as something special when really the unusual case/outlier here is the US.

The US has a bit of a culture problem on this front - everyone is armed to the teeth & violence has been made acceptable via Hollywood etc. Plus there is the old "if you have a hammer everything starts looking like a nail" issue. People will resort to what they have available. And you can't really do much about it because the gun freedom crowd will howl if you take away their guns.

I guess people will just have to keep dying.

I agree that 19 weeks of training for police officer in US is very low, and that leaves officers poorly qualified for their job.

On the other hand, the attached video of how British policeman handle a man with machette is nothing but pathetic, the kind of stuff that we regulary make fun of.

As the very minimum, if the policeman does not carry a gun he should carry a taser instead. This would resolve machette man situation in seconds, and only took one policeman to do so, instead of dozen.

> You don't have to be autistic to be driven mad by the constant interruptions enforced by office culture.

There's a difference between finding something completely pointless and stupid (an exaggerated "this is driving me mad!") and completely losing your ability to concentrate ("my productivity is 10% of what it was when I had a quiet room for myself"). I get so aggressive, hopeless and sad when overstimulated that I had to quit the job because open space was too much to handle.

> Can't ignore the daily standup though. It just means I will not be able to concentrate until 10:30 every day.

I purposely miss the standup meetings and just mail my report in instead. No one has complained, as my work still gets done and I still communicate with the team (although by Slack, not in person).
> violence has been made acceptable via Hollywood

Pretty sure Hollywood films are just as popular in all the countries mentioned in the article.

Unless they shutdown all your accounts and you are stuck with no customer support because customer support for consumers just doesn't exist.

I know of cases where startups were shuttered because google linked their employees to corporate account and if any employee has a banned account then all related accounts are banned too.

All it takes is one multiple sign-in and google ties up all accounts.

I have been stuck with a banned android account because of three strikes rules. Their own emails was in my junk folder (Thunderbird junk)

yes, be very weary of gun statistics, they tend to lump together hunting rifles and human killing devices. Given that many hunters are after small mammals and birds, many of those rifles are not really practical for criminality.

> More terrible than either of these tales is the
fable of the monkey’s paw[12], written by W. W.
Jacobs, an English writer of the beginning of the
[20th] century. A retired English working-man is
sitting at his table with his wife and a friend, a
returned British sergeant-major from India. The
sergeant-major shows his hosts an amulet in the
form of a dried, wizened monkey’s paw... [which
has] the power of granting three wishes to each of
three people... The last [wish of the first owner]
was for death... His friend... wishes to test
its powers. His first [wish] is for 200 pounds.
Shortly thereafter there is a knock at the door, and
an official of the company by which his son is em-
ployed enters the room. The father learns that his
son has been killed in the machinery, but that the
company... wishes to pay the father the sum of
200 pounds... The grief-stricken father makes his
second wish -that his son may return- and when
there is another knock at the door... something
appears... the ghost of the son. The final wish
is that the ghost should go away. In these sto-
ries the point is that the agencies of magic are
literal-minded... The new agencies of the learn-
ing machine are also literal-minded. If we pro-
gram a machine... and ask for victory and do not
know what we mean by it, we shall find the ghost
knocking at our door.

I'm not following you. I've had the police stop me plenty of times in order to ask for my ID and search me. The reasons were bullshit, and as a white kid, it gave me a little taste of what my black friends have to deal with on a regular basis. It is quite oppressive-feeling, to know you've done nothing wrong while having a cop saying and acting otherwise. That said, I do think you have a point, in that police departments can get disconnected from the communities they serve by becoming too focused on "getting bad guys". I'm a big fan of community-based policing as a result:

By hiring. Or, rather, not hiring.

At every single company I worked for we had huge trouble finding new people skilled enough to understand our product/codebase and extend it. A task that took a new hire two weeks to do sloppily would take any of our engineers about two hours to do properly. Recently we had one guy build nine prototypes of a test jig over the span of two months and none of them worked reliably. I ended up drafting my version one evening out of boredom (it wasn't even my responsibility) and not only it worked - it ended up being the favorite of our test team.

Needless to say, we had to lay off that engineer. He simply wasn't producing the value we paid for him.

I'm not saying there are 10x programmers. Maybe there's just 1x and 0.1x. Maybe it's 3.33x and 0.33x. But the discrepancy is there, and it's disheartening.

It may not prevent travel to Mars (for example, on a centrifugal space station), but considering gravity on Mars is 62% lower than here on Earth, I would postulate without some kind of gravity manipulation we are yet to develop (unless we have the energy to build centrifugal colonies on land) then manned missions on Mars would suffer a similar fate.

I intended these questions as broad examples though some are specific to a given AI system or architecture. You're quite right in that it depends on the task and the model.

I was thinking specifically about neural machine translation (NMT) with the encoder-decoder architecture. The encoder-decoder architectures converts a sentence in language X into a fixed size vector representation then aims to "expand" that vector into the equivalent sentence in language Y. As the vector size is fixed, short sentences can be adequately represented but longer sentences end up being lossily compressed. This realization illustrated a fundamental limitation in the encoder-decoder architecture and motivated the use of attention mechanisms.

There's a great figure (Figure 1) in Nvidia's Introduction to Neural Machine Translation[1] that shows the dramatic drop in accuracy with respect to the sentence's length.

There are people whose job it is to make pretty math, they are called "mathematicians" ;-) So much of early physics, be it thermodynamics, electromagnetics, classical mechanics, is genuinely beautiful and elegant. I can see why quantum physicists would strive for that ideal as well. But at the end of the day I agree that physics should favor creating testable predictive models over developing untestable, elegant ones.
I don't see how opening a glove box for a cop to look in is unreasonable.
Why does a precise definition of the discipline matter? AFAIK, there is no such definition of what constitutes physics or even mathematics. Those disciplines are usually "defined" by whatever it is that the people associated with them choose to study. Physics is as physicist does; philosophy is as philosoper does.
