That would be ideal. Unfortunately the boundary conditions are wrong. Since each end of the arrow is free, you get anti-nodes at the ends, just like in open air columns:

http://ks.kumu.net/Units/Waves/Sound/WebPages/Content_Harmon...

and nodes from the second harmonic (which dominate the motion) at about a quarter of the length in from the ends.

There is some black magic/hard engineering that goes into matching arrow stiffness and length against tip weight and bow strength to produce optimally timed and placed vibrations, but I've never dug deeply into it.

What happens when the tech bubble bursts?

Yes, certainly we live in the information age, and there will always be a need for tech workers, but the demand will fall with the economy. So isn't there an element to short-term gain for people who went into tech simply because of the past decade?
That'd probably depend on the industry. But even if they didn't, the way to solve that would be by increasing the reputation of MOOC certifications, not by doing away with them entirely.

When I was still a fairly generic STEM kid, skeptical of "feminism" and a bit tempted to oppose it via "egalitarianism" or something like that, I got into an argument over the internet where my opposite said this:

"Mainstream, sex-positive feminism is about equality and is concerned with the rights of men whenever they're in question. I'm a total feminist who believes that the significance of male rape is hugely devalued by society, that family court relies on outdated standards, and a few other 'MRA' bulletpoints. I find nothing but agreement when I pursue these ideas in a public, academic, or otherwise serious sphere. The Men's Rights movement, however, is not a legitimate offshoot of a cruel and uncaring feminism. It's a reactionary, hostile internet culture that inevitably finds itself tied up in aggressive takedowns of feminism, responsible for fomenting a lot of denial of its legitimacy through a cherry-picked view of fringe perspectives, poorly considered, half-scientific 'biotruths' and a thin veneer of concern for the rights of men.

Feminism is not called feminism because it hates men. It's called feminism because it comes from societies with a history of gross, outrageous repression of women. As we move closer to equality, it becomes natural that men should involve themselves in the movement and ensure that it considers their rights as well. But feminism does that. MRA denies that only as a stepladder to get into a denial of the legitimacy of the female accomplishments of feminism. That's what it is at its core."

I was very impressed. I conceded, and it's stuck with me to this day.

I haven't used Haskell in teaching either. It probably is. My professor does not like lazy evaluation at all (note how i did not insert it in my "haskell light" list of features), he said he played with it at the time this stuff was being researched but he never saw the benefit to offset the complication in semantics.

Our students were mostly having trouble with OCaml being a functional language than anything else. Some of them independently discovered mutable references and for loops and probably wondered why we hid from them such useful constructs! Pattern matching was also something that only the best students took serious advantage of.
Your comment seem phrased to imply the current Ellie system (featured in the article) doesn't read sentiment (when you write "will have to be" about incorporating sentiment- that usually reads that an existing system like Ellie doesn't have that"). From the article: "When I answer Ellie's questions, she listens. But she doesn't process the words I'm saying. She analyzes my tone. A camera tracks every detail of my facial expressions."
I agree that this trend is disturbing, but am unable to reconcile your alarmist language with the numbers in the links you provided.

I do not support private corporations (or even public good -- yes, I think the chain gang days of old are similarly awful) making money off of prisoners. However, from the articles you linked, some data:

* 2 million (2,000,000) inmates in federal/state/local prisons.

* 100 private prisons, 62,000 inmates in them (6.2%)

* 18 corporations guard 10,000 prisoners in 27 states (unsure how this relates to previous point, the article isn't very well written and doesn't connect these numbers)

* Forbes.com article says there are 6,000 prisoners in the US serving time while working for a private enterprise.

So on the one extreme, we're looking at 6% of the prison population being affected by this. At the other extreme, there are only 6k prisoners affected.

I believe there are a huge number of ethical and moral violations surrounding the prison side of the US criminal justice system. Private prisons are one of them, but hyperbole and extreme language do not serve any of the population.

I've said many times that if I was ever on a US jury (which would never happen; I'm Norwegian, living in the UK, and even if I at some point where to be resident in the US, this attitude would get me out of jury duty very quickly:),

I would have a hard time voting for a guilty plea except in the most exceptionally horrible cases, because I would find it exceptionally hard to justify making anyone suffer through the US prison system. That would include if it was a murder trial or similar.

Not only do I find the US prison system immoral for its treatment of inmates, I find it immoral for the violence it is indirectly responsible for inflicting on wider society by actively treating people in a way known to at best be ineffective, and at worst having a massively negative effect on re-offending rates.

Anyone worried about violent crime in the US should start by demanding reform of the prison system.

"Eventually - around 2000 - everyone understood
this, and gave up hoping some subculture could
somehow escape this dynamic."

The whole article is really about music, and carries continuous undertones relating to the mechanics of music scenes.

So why 2000 as the magic year music died? The Internet.

That's the whole answer. The internet killed music. Not just because of peer-to-peer file sharing, but so many other aspects of pre-internet music economies simply didn't make sense anymore, from composition, to production, to distribution, to consumption, all aspects of recorded music were turned inside out and flipped upside down.

Sure, performing music hadn't really changed all that much, but the controlled release of physical copies of music simply didn't work anymore, and so The New Thing wasn't permitted to steep in its own Newness, and fester and grow moldy and get weird anymore.

The transformation of distribution technologies from 1990 to 2000 was like taking a healthy adult St. Bernard, and replacing all of its internal organs with the organs of 50 kittens, and expecting it to come out healthier than before. Except the St. Bernard's brain doesn't know how to breathe with 100 kitten lungs, or pump 50 kitten hearts, or swallow food into 50 kitten stomachs and digest vital nutrients.

From a technology perspective, with music, where we are now, is like where music was in 1950. We're still figuring out the new capabilities of what can be done with this technology, the same way people back then were still figuring out amplifiers and feedback and taped distortion. In that respect 1990 is still 40 years away, culturally speaking. Longer still if more disruptive technology keeps getting introduced, and upsetting established skills.

There are no more geeks to create scenes, because geeks haven't had enough time to learn the vast depths of modern technology, to master it, and spawn new scenes.

Maybe to stop a rush on cash deposits in the case of a banking scare out of hours? ie. rumour / announcement that the bank has run out of money. Seems unlikely.

More likely is that it's to save money - if there is a cost incurred in supplying money for other banks or keeping the machine filled with cash, perhaps reducing hours is simply a cost saving measure.

"Jail"... of course.

Nothing in his story suggests jail, not even the tax evasion hinted at.

Certainly not the "Abmahnung" by a competitor. That's a civil matter.

Basically it's the same old story, as it happens with ebay a hundred times every day: guy thinks that he might get away with "selling privately", thus getting rid of consumer protection laws (that's the real issue here, not taxes, unlike all the speculation on reddit).

Commercial competitor - or sometimes the authorities - believe he's selling commercially.

Just to add to the discussion of these two language levels, there is a new research language called 1ML that unifies both levels:

http://www.mpi-sws.org/~rossberg/1ml/

"a redesign of ML in which modules are truly first-class values, and core and module layer are unified into one language. In this "1ML", functions, functors, and even type constructors are one and the same construct; likewise, no distinction is made between structures, records, or tuples."

> How about "ask a blonde person"?

I've played that role.

I lived in Japan for 8 years, some of it in provincial areas. I have blond hair. You would be shocked at the number of questions I got about having blond hair. The most common one was "Can I touch your hair?"

More thoughtful ones were about hair treatment (I was told that my hair is quite fine by Japanese standards). While I didn't do anything special, and not all blond or Japanese hair is the same, there seem to be some treatments that differ based on the type of hair you have.

I am sure that my barber in Japan wished he had a Japanese version of "ask a blonde person" when I first walked in the door, because my appointment apparently caused him to stress out massively. I found this out later as my Japanese got better and I became more integrated into the community.
Looks like a research proposal based on this paper: http://arxiv.org/pdf/1305.5278v4.pdf

ZeroMQ (in certain configurations) is broker-less if I recall correctly. The clients connect to each other, rather than going through a broker.

Last I checked, ZeroMQ is more of a "low-level" library/framework that provides easy-paths to more higher-level functionality that would be comparable with what you'd expect from a standard message queuing system.

Anyone got a different take from it? I only did the tutorials quite a while back.

I am a car nut, love driving, drive a powerful car, and can't wait for more of the autonomous cars to hit the streets. Like the article says, they operate predictably and safely. Sometimes it feels like everyone around me is acting like they are a teenager on their first day of being licensed.

I live in the USA, and feel that I am a more skilled driver and more mindful than most people who I share the road with. I do not want to be banned from driving. I operate the vehicle safely, strive to obey traffic regulations, give my full attention to driving, and despite having a powerful car almost always drive in a manner that minimizes fuel consumption.

Maybe rather than banning human drivers, the standard for obtaining a driving license should be raised. When I have driven in countries with higher standards, like Germany, it's seemed to me that there's much less chaos on the road and drivers are more responsible. There are definitely less of the metro California style shenanigans the author is talking about.
> I don't think programming languages implement decorators in order to facilitate

Well, in JavaScript, it’s particularly easy to write decorators as plain old JavaScript functions. Lots of libraries provide implementations that provide memoization or parameter checking on both functions and methods.

So in the short term, decorators serve only to work around the fact that ES-6 classes actually make this more difficult than ES-5 idioms.

But in the long term, a decorator can be extended to deal with static analysis, while functions provid eno such capability, so we’d be back to having “magic comments,” or inventing a new kind of pragma.

So, I’d say that the motivation is to lay the groundwork for things involving static analysis or manipulation of programs. Like type checking, or even manipulation of the AST.
Yes, in writing ruby during my day job, I often have conflicting feelings about dynamic typing. The other advantage would be being able to do real static analysis, I would love that.
It's fine building a prison on the premise of second chances, but it will fail if the society it belongs to isn't build on the premise of offering a second (or third, etc) chance.

Either you believe in the ability of every human to change their behaviour, and you give them a chance to... every time... or you don't.

This, I feel, is tied to the death penalty too. Societies that give no second chance do not seem to worry too much about killing people.

That is, at the very best, an extremely simplified extreme opinion.

Victims have every right to hate their offenders and a just society should do everything they can to help the victims, including punishing the offender. I don't get why this is an extreme pov but apparently it is.

Although that it's not important how MOOCs changed my life , but i will tell you how , i was raised in a poor family (like really poor) , i got my first computer when i was 16 years old , and saw the internet for the first time when i was 18 years old , i always had hunger for knowledge and learning new things but never could go further than reading some old books from the high school library , when i first got the internet access it was just the beginning of the MOOCs and i was amazed by the opportunity it gives , given that i always loved computers and the "magic" behind it , i started my first MOOC at that time which was CS50 by David Malan in HarvardX (Edx) , and never stopped MOOCing from the the three platforms , now thanks to MOOCs and of course practicing on my free time i am a 20 years old full stack developer, i am still a junior developer ,but i gained enough money to change the situation of my family from worse to the better, while most of my peers still studying in our system (I am studying too and graduating this year from electrical engineering) , the real difference is between our education system and the MOOCs , i have to emphasize that there is no way to compare the quality , and of course the price (which is free) , i really encourage everyone to never stop learning from MOOCs because knowledge and new skills can create a completely change a life .
