We propose an alternative approach to construct an artificial learning system, which naturally learns in an unsupervised manner. Its mathematical prototype is a dynamical system, which automatically shapes its vector field in response to the input signal. The vector field converges to a gradient of a multi-dimensional probability density distribution of the input process, taken with negative sign. The most probable patterns are represented by the stable fixed points, whose basins of attraction are formed automatically. The performance of this system is illustrated with musical signals.

If the Moon were made of fuel, it would still not make sense to land there and take off again.

This scenario describes setting up a Moon base and then shoot fuel into LEO (either directly, or with an electromagnetic catapult). From LEO, the fuel is indeed useful, but the industrial infrastructure may be excessive unless you're talking... low-hundreds of launches?
Let me preface with what I'm about to say with this: I am very pro-equality in all aspects. Also, I am not a supporter of this new-wave Feminism which is full of misandry, anti-patriachy and other similar bullshit. Men of all skin colours get discriminated every day by women, too. Yes, women are not magical all do-good creatures; they can be horrible, regardless of skin colour. With that being said...

However, I am afraid we'll soon have this trend where a black woman[1] with lesser qualifications will be hired in favour of a white man with better qualifications, simply because she is a woman and black. Same applies for speakership (or whatever you call it).

That's not equality.
> If that's the case then I'd call out what I think is an incorrect assumption; that technical ability is perfectly correlated with either productivity (as an employee) or interestingness (as a speaker).

OK, that's interesting and a good point.

> While it's not conclusive, there are studies that show that diversity in the workplace correlates with increased performance

But how should that affect a hiring manager? Should they round-robin through categories of people for each hire? Isn't that just reverse-discrimination? (Or "regular discrimination" if it's the WASP straight male's turn to get hired.) Doing one's best to look past those labels seems to make sense, but the article seems to say we need to consciously label and balance the representation.
Interesting article. The 18th and 19th century are foreign enough to make you smile incredulously -- the overall imagery, cocaine toothache drops, Restorative Nervous Cordials against masturbation -- and are, at the same time, very relatable: a somewhat industrialized world with global travel, universities, advertisements, to name just a few themes that come up in the article. It almost feels like a satire of the modern world.

And of course, as the article points out, quackery is far from dead (though it's a matter of opinion where exactly it starts). Then as now, there's fertile breeding ground: lack of education, lack of resources, a “sufficient number of hypochondriacs” and the legion of bored, unhappy people suffering rather vaguely from “nerves”. Striking, isn't it?

Let me hasten to add that it's very likely that many of those people were genuinely sick, and it just took us another couple of centuries to find the technology to diagnose and treat them. Though if you're of the persuasion that includes Big Pharma in the quackery camp, maybe it's the quackery that got more refined instead.
I think CSS is wonderful, but the real tragicomedy is Bootstrap and Foundation grids which have CSS classes and Divs that are just as much management and just as much code as tables yet are very arguably less functional. Reliable vertical centering anyone? Now can you do it without wierd hacks?
The necessary innovation to reduce time spent on household work is likely to be a cultural shift away from owning physical things and towards digital media. Arguably it's already here - CDs, DVDs, games and books are all available digitally now, so we don't have to keep shelves of media clean and tidy. Once people move away from owning art, pictures, plants, etc and replace them with digital versions instead then cleaning will become a trivial 5 minute job.

I think the price point here is about a couple of things:

- Chef and Puppet are too expensive for most companies to acquire, and have too much operational cost for too little revenue

- Ansible got a strong following in the SMB space, Red Hat probably thinks they can move that upmarket some

- Ansible's agentless configuration management has potentially strong applicability in a container world (why do I need a chunky agent to configure resources on my docker image? What if, for some reason, I need to affect change on running docker images? - I realize this is a bit of an anti-pattern for docker, but it was something I heard a lot from big enterprises)

$100m still sounds very high, kudos to the ansible folks who have come a long way in the last few years.

EDIT: one more piece I didn't think of here - the openstack side of things is an area where Red Hat has made big long-term bets for the future of the company, and it probably helps to justify the price in terms of backstopping their openstack support.
I thought the Martian was excellent. You'll notice that the user-rated % is higher than the critics, at 94%.

From the video game aggregation space, you tend to see the type of thing you're suggesting (games that are big-budget-questionably-reviewed) have _much_ lower user-scores than critics. I would be surprised if user-rated movies was different.
The main reason: With all these treaties, the world is going to be gradually reshaped into a world optimized for corporation profits. In such a world, humanity and personal rights (of the less than billionaires) are of no value (your value to society is calculated by your bank account and potential to "invest"). Instead of human rights, the "right for profit" for the corporations is established (nothing else are those courts of arbitration, that shall be established for example with TTIP).

Stanford did not pioneer investments in alternative assets classes (VC/PE etc...) Robert Swenson of the Yale endowment fund was much earlier than that. It also became known as the "Yale Model"

===

For the two decades after Swensen took over as manager of Yale’s endowment in 1985 (just five years after he’d gotten his economics Ph.D at Yale), this worked spectacularly well — with a 16.1% annualized return compared with 12.3% for the S&P 500 and a remarkable record of sailing through stock market downturns that pummeled most other institutional investors.

https://hbr.org/2010/04/why-the-yale-model-of-investin/

===

The prevalence of Swensen acolytes in leadership posts highlights how dominant the Yale investment model has become among major U.S. universities. Colleges and universities ended 2014 with 51% of their portfolios invested in less-traditional fare like hedge funds, private equity and real estate that Yale favors—nearly double the allocation to those investments in 2001, according to annual surveys done by Nacubo and Commonfund.

http://www.wsj.com/articles/universities-look-to-yale-for-in...

===

Swensen’s idea, implemented at Yale and copied nationwide, was that universities should shift their endowment money out of traditional investments such as stocks and bonds and into higher-yielding ones like private equity, hedge funds, and real estate. The Yale model, as it came to be known, perennially outperformed stodgier strategies, gaining Swensen gurulike adulation.

They might be putting up $10 million a year.
In the context of a $22 billion dollar endowment this seems minor. All that money has to be invested somewhere, this isn't drawing it down.

In an employment market, I am the supplier, my boss is the consumer. I hold a monopoly over my supply. All of my competitors offer my employer a slightly different product. The market is a monopolistic competitive market. On the other hand, my boss holds a temporary monopoly on my income, whether I eat or not.

With a GBI, these monopolistic parts of the market may be removed. My boss does not have to choose between me and another employee offering slightly different products, we can both be hired for the distinct bits of work we are can provide, and for an agreed price we value the work at, not an amount we need to satisfy our need to live. ie.it opens the employment market up to purer competition.

Is the argument for BI really...

Let me be clear, I don't think this is a good thing, but that is the sense I get from pro-GBI advocates. The scary thing is it most probably would be massive, in time, and there is little good evidence on the knock-on effects. I get why anti-GBI advocates are scared, they stand to lose money, but pro-GBI advocates should be scared too. So I guess what surprises me is they both should be arguing for trials, surely?

There are plenty of confounding factors with your own "easy test", some of which you admit yourself- the stress of the life in general. Who's to say that living a neolithic existence isn't stressful? Indeed, it probably is far more stressful. This has nothing to do with electric lights and computers. This is just life in general. At least you can take a break every so often.
It's never going to be impossible to access these devices (and I suspect Apple deliberately doesn't make it too hard). But every year it gets more expensive, riskier, and requires more specialised knowledge. Modern BluRay keys are already out of reach for a casual home user (speaking as someone who tried to play my own BluRays on Linux). Soon we'll be at the point where you need a cleanroom and an electron microscope to bypass protection.

These two are exactly what bugs me, too. This actually reminds me of how Feminism turned from an equality movement to this modern-wave bullshit where it's a woman-supremacy movement and it's got nothing with equality.

It seems like 2015 is the year where people started being offended by everything, and they constantly look for opportunities to be discriminated. "Black women in IT."

Fucking Hell, by the time it's 2020 we'll reach a "homosexual Black Christian women wearing polka dot clothing in tech indistry" that are being discriminated.

Current generation drones don't handle severe weather conditions very well.

Even larger military drones, such as the well known Predator, have severely limited crosswind components.

http://middleeast.about.com/od/usmideastpolicy/a/predator-ua...

"According to the Project on Government Oversight, the Predator "cannot be launched in adverse weather, including any visible moisture such as rain, snow, ice, frost or fog; nor can it takeoff or land in crosswinds of greater than 17 knots.""
Those could be contradictory. If you're consciously categorizing people in order to "be inclusive", you are discriminating ("make an unjust or prejudicial distinction in the treatment of different categories of people or things"), and probably instituting your own mental quotas to monitor the balance.

If you just mean don't throw "Latoya's" job application in the trash just because she sounds Black and you don't want any of those, few here are going to disagree, and few here would do that either, so it's not very helpful.
Just my opinion, but the idea of "50% women speakers" isn't out of some sort of over-representative fairness to a "minority", but a reflection of real world demographics.

In any case I can think of, roughly 50% of people in a given conference's catchment area are women, and since tech is an industry in which anyone could excel, having "50% women speakers" is promoting and encouraging a desired ideal to both the industry and potential participants in that industry. (I must note that "failing" at having 50% women speakers at a conference is by no means a fatal flaw, but having the ideal there and the principles in mind can still effect long term change.)

The idea of having 50% "trans" people at an event would be a very different one given less than 1% of people are trans, allegedly (although given the stigma still attached, I think being trans needs to become more acceptable in society as a whole before we'll know the true number. They're probably a lot higher than we'd suspect, as we saw with homosexuality through the 20th century).
Agh I wish people would either read some of Christensen's work, or even the basic Wikipedia article, or else stop using the word 'disruptive' in this context. It's diluting a concept which used to have a very specific meaning, and has rapidly changed to mean nothing, through misuse.

This article starts off by almost calling people out, saying that people use 'disruptive' in the wrong way, but then it proceeds to make the same basic errors.

There are a few key characteristics of a disruptive innovation. One is that incumbents don't notice the changes due to market myopia. Were competitors to the vacuum unaware of the technical leaps possible due to technology? I will bet not. Another key characteristic is that it causes competitor value-networks to change. What value network changed by vacuums being adopted? The hitting-rug-with-stick value network? How much value flows through this network? Did the sweeping brush value network change? No, everyone still has a sweeping brush even now. All that happened was that consumer demands changed and a new product was adopted. But wasn't it still an amazing leap in technology? Yes! It was a 'radical innovation'!

"Disruptive" does not mean "big change". It doesn't mean
"impressive". It doesn't mean "unexpected competition". In this case, it doesn't mean "society changed over the course of a century as a new industry was created due to ancillary technological improvements".

It certainly doesn't mean "normal dynamics of industry and competition", which is how most people seem to inexplicably use it.

The key part seems to be that Homo S. avoided Europe during the better part of the last ice age, while the Neanderthals lived there (but the Neanderthals didn't live in Asia).
The choice can't possibly be "always between two or three competent". Less competent exist, and they have to pop up somewhere. With quotas, once most competent from the lesser set get taken, only less competent will remain available. It's a trivial mental exercise, not something that requires gathering evidence to figure it out.
For reference, Gamma Group are a well known bunch of evil bastards in the UK. Nothing they do is considered honorable. Literally nothing.

It says everything about the place when I had my CV put forward by an agent a few years ago for a "high tech position" in the "expanding data sector". Wouldn't reveal who it was to start with due to an NDA. Moment I got told who it was, it was "fuck off". And you know what I got stick from the agent for actually having some ethics. Clearly it's not common these days otherwise outfits like that wouldn't have any staff.

Then again they seem to groom people without experience or understanding of exactly what they do at university job fairs.

Meta-law is what law writers use to justify writing the local law. In Sweden we saw this promoted heavily in regard to data retention, where the law makers explicitly said that we "had to do this" because the meta-law bound Sweden to implement a compatible local law. If one party blames the local law, and the other party blames the meta-law, then all we have is people pushing blame without anyone taking responsibility. A way for me then to avoid hair-splitting in this case is to blame both sides for the full legal change, as TPP will be a law in itself for all practical and political purposes if it get signed.

QQ.G.17 has no hard obligations, and is only a suggestion that nations should "endeavor to achieve an appropriate balance". That is like me suggesting that government should "endeavor to achieve a fair balanced budget". It doesn't actually say anything concrete, dictate policy, nor impact the political environment in any way at all. It's there to provide a good-feel nod, while the law makers can focus on the actual TPP obligations. EFF remarked this in their article a week ago (https://www.eff.org/deeplinks/2015/10/final-leaked-tpp-text-...).
Agreed.

I'm a serious movie fan. I've seen more movies than the 99.999th percentile of the worldwide public. Officially filtered for a number of film festivals, including at least one you've heard of.

And I still give heavy weight to certain reviewers for general release films. It's all about finding people you more or less agree with.

Before the microcomputer most technologies were totally hackable and often buildable from scratch. Out of the things you had in the 60s, probably only TV could not be built in-house. Radios? Washing machines? Cars? All could be constructed by general population with various levels of effort. But what's more important, all those things were user-servicable, user-modifiable and it was a popular hobby to tinker with stuff.
