Welcome to Hacker News! I don't mean for this to come off the wrong way, but please try to put more effort into your comments than Imgur links. This is a place for discussion, not one-liners and images. It may be that way on Reddit, but Hacker News has a focus on higher effort content.
I think the author of this article makes a compelling argument for why building a recommendation engine is not an efficient strategy in creating an MVP. I've been working on an e-commerce startup for over a year now (eep!) and after spending countless hours arguing over this exact prioritization with my co-founder, I had to finally call it quits, because we just never got anywhere. Recommendation engines sound sexier when pitching ideas, but at the end of the day, how do you pitch a product that doesn't exist to customers that only exist in theory?
A friend of mine who knows Professor Robert Sloan

http://www.cs.uic.edu/Main/Faculty-Area

(I've met Professor Sloan directly once) told me about the article submitted here. He has a conference paper coming out for the AAAI conference next week,

http://www.aaai.org/Conferences/AAAI/aaai13.php

with more details about the research. It looks, from the first few comments submitted here, like many Hacker News readers think either

a) that the article wasn't sufficiently respectful of the field of artificial intelligence,

or

b) that the field of artificial intelligence deserves no respect.

But my understanding of Professor Sloan is that he takes artificial intelligence, his main current topic of computer science research, very seriously, and he is well aware of the societal importance of artificial intelligence research. Maybe the message was lost in the ComputerWorld reporter's treatment, but perhaps the conference paper will set the record straight.

On my part, I was glad our mutual friend told me about this article, as only today I completed an extensive edit of the Wikipedia article about IQ classification,

http://en.wikipedia.org/wiki/IQ_classification

so I've been pickling myself in scholarly writings on IQ testing recently. My friend is aware of that, and I think shared this link because of the angle of giving an IQ test designed for a human child (the WPPSI is strictly a preschool-age test) to an artificial intelligence system. Of course, we expect artificial intelligence systems to do different things from what preschool children do, so it's not surprising that an "expert" artificial intelligence system might not score high on a human IQ test. I'll read the professional publications when they come out to find out more.

Are any of you going to the AAAI meeting?
Willpower requires an expenditure of glucose in the brain [1]. When one is used to a high-sugar diet, the blood sugar burns off quickly, despite being slowed by insulin response, and the body craves more, with the brain being glucose-depleted to resist the impulse. This is not to absolve anyone of personal responsibility, but like gambling, it is a losing proposition over time.

The fact is, we're all wired a little differently. Some who drink too much can simple moderate; some find the need to temporarily or permanently quit drinking altogether. Anyone trapped in the "metabolic syndrome" of a sugary diet will probably be more successful doing the latter.

Most HFCS in use today is a mixture of 45% glucose / 55% fructose. Sucrose is 1 glucose molecule and 1 fructose molecule bonded together. If fructose is really the 'bad' thing here, then HFCS has more of it.
I'm aware of that; it's the other reason why the HFCS hypothesis is broken. But it's much easier to draw the international comparisons.
Yep. Sometimes crashing isn't an option. There are places in network & systems code that have seemingly complicated but darn important many permutations of state that already exist. Sometimes the differentiation between error conditions requires a combination of conditions (i.e., talking to an existing legacy system.)

As for single-threaded map, there are at least two necessary behaviors that handle errors very differently:

1. batch all errors/exceptions/etc and return them as an array
2. return on first error
Porta generates Clojure abstractions for existing Java Classes
If it comes in a box, don't buy it.

Personally I think this is pretty extreme/bad advice. Plenty of over-processed foods don't come in boxes, and plenty of perfectly acceptable foods do come in boxes.
Which is a question of satiety. The tl;dr is: eat protein and stop drinking sugary liquids.
Well, Apple was the last of the bigs to buckle.

Very very interesting stuff. Looking forward to where you guys go with this. If implemented well, this COULD be the new geocities WITH backend. Loving it
Zswap looks very interesting. It seems that a similar feature is included (and enabled by default) on the new OS X Mavericks (http://www.apple.com/osx/preview/advanced-technologies.html -- called "Compressed Memory").

As a Windows user, I'm always surprised to see how conservatively Linux uses its swap area. On Windows, even with enough free memory, it still pages to disk and gives me a sluggish experience.
Does anyone have any idea why Windows is so aggressive about paging disks out compared to Linux?
> "All of us know a huge number of things," said Sloan. "As babies, we crawled around and yanked on things and learned that things fall. We yanked on other things and learned that dogs and cats don't appreciate having their tails pulled."

Then let the damned thing explore! Why do we make such huge advances in robotics if not for this? A baby-like robot shouldn't be that hard to make. I'm no AI expert but couldn't we just throw our best learning AI in there and give the thing a couple of years?

Why are we trying to short-circuit human learning instead of mimicking it?

It seems interesting but I did not get it. Does it try to add some c++ syntax sugar? Does it have performance advantage over c++ for similar functionality?

Those summaries were quite fantastic. I agree that perhaps it is unnecessary to use them for the selected entries, but feel like they must be useful somewhere else.

Perhaps it would make the most sense to have an rss reader or similar with the summarizer built-in. Or a page with links to medium articles (plus others) with summaries.
Definitely not. For some reason there is a persistent myth that investors make money from HR acquisitions, but they don't. Even we don't, and we invest at much lower valuations than VC funds.
Corn is very starchy and low-nutrient. I'd suggest swapping them with something green, like canned peas.

Still, I applaud your approach. I've been on paleo for about a year, lost a bunch of weight, and for a while I was basically eating the same 12 foods on a loop (eggs, bacon, coffee, lamb, shrimp, fish, broccoli, spinach, carrots, raspberries, dark chocolate, almonds).
I've had some intense anxiety issues, though not as intense as the thread parent.

I too found that changing my diet and exercising helped.

One of the most effective methods for me is meditation.

Ironically, during meditation, you also accept the anxiety. Or to be precise, you accept the experience of anxiety. The thing is, I also know that all things are transient. That includes anxiety. If you mindfully observe anxiety as it arises, you can literally see it created, come into full force ... and then start fading away.

When the mind starts avoiding the experience of anxiety, it tends to get stronger. Further, the avoidance itself triggers secondary waves of anxiety, so you enter this feedback loop of anxiety.

Ultimately, anxiety is the feeling of avoidance. If you've gained the skill where you direct your awareness at the anxiety itself, you start being able to see things more clearly.

You can learn about this through http://www.urbandharma.org/udharma4/mpe.html or participating in a Vipassana retreat.

There is also the method described by this book: http://www.amazon.com/Feeding-Your-Demons-Resolving-Conflict...

There are also carefully conducted entheogen sessions that can help treat this.
I think that technology is amazing. It was a really cool way to demonstrate it, because I had already read some of those posts, so I got a sense of how accurate the summaries were. I would love to know more. Great job.

Question: Why do I have to implement hyperparameter selection?

For me, the promise of in-the-cloud machine learning is that I can call 'train' method, and specify one single hyperparameter: training budget (i.e. $). Perhaps also the max time before I am returned a trained model.

That's it. Can you do that?
Right now he has been noticed by almost every politician in the world. Prime ministers and presidents mention him and everyone is wondering what will happen to him. Perhaps he wants to keep the focus on him until he is granted asylum.

It makes sense to produce a slow stream of information so that he doesn't become old news. If the media starts ignoring him the politicians may not care as much.
I think it is pretty clear that the person you are responding to is pleased with the progress Yahoo is making. Criticizing them for still being a part of PRISM is not entirely fair as I imagine these companies are all being coerced. To see good news about Yahoo taking an anti prism stance, see someone say "I'm going to use Yahoo products more" and then say what you said seems a bit disingenuous honestly.
Somebody should make apple stop forcing developers to do things. That apple made the choices very simple and deployed hardware widely had nothing to do with it.

It's almost impossible to find canned peas without added sugar, sadly.

Thanks for the list of paleo-safe foods!
Yes and no. You could argue that use of passwords or private keys is security through obscurity, but that definition is pretty meaningless. Security through obscurity doesn't really apply when you can make the search space arbitrarily (often exponentially) big very cheaply, as is the case of URLs here.
we skipped what would traditionally be called a series A and series B and went straight to a growth-staged round with Sequoia
Unlike the others, I completely agree. Art that does not "express, explore, or otherwise stimulate the human mind"[1] is the definition of boring.

I would however claim that the vast majority of art does stimulate the mind, though it may not stimulate yours without some additional effort. Indeed just about anything in the world is capable of stimulating your mind if you look closely enough at it, to paraphrase John Cage.

[1] ... or, if we take a 'vibrant matter' / 'object oriented ontology' view of the world, stimulate something.
... and similarly, it's in YC's best interest for valuations (of YC co's) at Series A to go up ;)
So wait, if PRISM is merely the process by which NSA et al request data on individual suspects which are then reviewed and fulfilled with human involvement (as the denials by Google etc purport)... why did Yahoo see fit to challenge their involvement?
It's just anecdotal, but it is a lot of anecdotes. Both of my parents are professors, one at a much more prestigious school than the other. I've worked for a regular publisher, an academic publisher and I went to graduate school myself, so I've had a chat about this exact situation many times, though I admit I have no hard data.
I would be more worried about the amount of medicine residues in the meat than the stuff that's actually "supposed" to be there :P
I see what the article did there; switching from "real intelligence" to "intelligent behaviour". Not that "real intelligence" is well defined, sure; but that also means you can't just claim you achieved it nilly-willy.

Michael Kearns suggests that "people subconsciously are trying to preserve for themselves some special role in the universe". By discounting artificial intelligence people can continue to feel unique and special.

Right. Then why do I have no problem, and actually enjoy, noticing similarities between me and other animals or even plants? Even two electrons occupying different places at the same time could be argued to both be "unique and special".

What would make humans special in the face of even the most advanced AI is that we built it... and who, other than a lunatic or someone escaping from themselves, would look up to persons in a play he wrote? Don't mistake for jealousy what could also be explained with paying attention, that'd be my suggestion.
completely agree with PG -- acqui-hires aren't a big source of capital returns at all, especially anything below $10M.
Only in person.

I like to ask questions, and make suggestions.

I wouldn't want to watch someone code something I have no context of in a language I barely know when I can't actually talk to them.
Secrets! We test things like that for quite some time before we release it. We know it's good when coworkers start asking, "Wait, this isn't shipped yet? Why not?!"
> After a lot of self-analysis and experimentation I discovered that about 70% of the problem was the Pepsi I was slugging down every day. For my body, sugar and caffeine together are like crack. I switched to diet and dropped about half of my daily anxiety in a few months. I eventually cut the caffeine out altogether.

This, so many times over. When someone comes into /r/adhd and asks "I'm having troubles with anxiety, help!" my first response is "cut out caffeine then come back in a few weeks."

People do not realize, caffeine is a drug, it has side effects. One of those side effects is anxiety.
How does such a system work with very hot matter, e.g. plasma in a fusion chamber?

I assume some sort of medium (i.e. not vacuum) is needed to propagate the waves, and that at the temperatures necessary for fusion the medium would turn to plasma and the vibrating plates would melt. But I'd certainly like to be wrong.
The title is a bit of an overstatement.

It can recognize vocabulary words as well as a four-year-old. Not much more.
i will defer to PG & YC in terms of their data on valuation/caps post-demo day, however our experience is that they probably reached a local max sometime last year, and they are certainly softer this year.

in general, most companies with similar progress are being valued less highly than last year.

which isn't to say they are either cheap, or a bargain -- just not as high as last year.
A friend of mine teaching trans-personal psychology told me once that there is a difference between anxiety and panic. When you are panicking, the feeling is so intense that you don't know you are panicking. If you have the presence of mind during the experience to know you are experiencing this feeling, this would be anxiety.

The rubber band thing works because it interrupts the usual pattern of feedback loop where the anxiety builds and feeds on itself.

You mentioned breathing. You are talking about deep, yogic breathing? This is where you engage the diaphragm, ribs, collar bones, breathing smoothly, deeply, and quietly.

In any case, I found that anxiety, like procrastination, is the symptom rather than the cause. Anxiety arises from deeper issues. Those deeper issues are addressable.
This is what I want to see happen. I want to see categorical cross-referencing events/things where round is applied to ball and ball is applied to basketballs and baseballs. I want to see orange applied to basketballs, and then a connection is made between the fruit orange and a basketball. And just let that thing work, just leave it unassisted for a year as it grows more and more connections and see where the lexical processing and visual (color and shape matching) processing takes it.
Some of us want to have the debate about the concept of "homeland security", while we are at it we can talk about having a department of peace instead of a department of defense
I totally agree. Lateral thinking is so much harder to program and architect than logical thinking - we don't even have a good operational definition for creativity that is rooted in physical space and in a conceptual framework.

This article shows how the fructose industry is defending itself. Mostly by confusing the issue.

The thing about fructose is that it is not by itself poisonous. The problem only comes about for refined fructose, such as that found in cane sugar and HFCS. In those cases, fructose overwhelms the liver and gets processed by wrong pathways which result in all kinds of problems. But if you eat fructose in the form of fruits and vegetables, your body has to take a while to break the fructose out of the fruit and vegetable cells. Thus, your liver only gets a steady trickle of fructose instead of a flood of it. As a result, the liver can process the fructose correctly. Furthermore, if you eat fructose with fiber, molecules from the fiber help the liver process more fructose correctly.

Knowing this, it is not difficult to construct an experiment that shows that fructose is not harmful. All you have to do is feed your subjects the correct form of fructose (i.e., fruits and vegetables). The experiment where subjects ate large numbers of apples and were perfectly ok was quite telling.

The other defense of the sugar industry is that it is not the sugar, it is the overeating. However, refined sugar causes the overeating. One of the results of processing fructose the wrong way is that the liver does not produce the hormones that are supposed to inform the brain that you are full. Thus, refined fructose causes overeating of sugar and anything else you happen to be eating with your sugar. Personally I know I eat much more fries if I eat them with ketchup and I will eat much more steak if I eat it with steak sauce.

The fat people and diabetics are being blamed for eating too much and lacking willpower. They may be partially to blame, but it is very hard to make the correct decision when your brain's own sensory mechanisms are being hijacked and tricked. It is very hard to stop eating when you are constantly hungry. But if you cut down on the sugar you will not be constantly hungry, and then you may find that you do not even need that much will power to cut down on your calories.

Note that the standard Solaris versions of many commands are substantially faster than their GNU equivalents in the 'C' and multi-byte locales so this advice doesn't necessarily apply.

That's part of why Solaris continues to use them in favour of GNU alternatives (although the GNU alternatives are available easily in /usr/gnu/bin).
The article merely explains how perceptions are formed of AI research as a failure of capturing the essence of intelligence. Once an aspect of intelligence is understood, replicated, or improved on, it is no longer intelligent...it is reduced to mere computation. AI may not have captured the essence of human intelligence yet, but it seems to be doing pretty well with substantial aspects of it, given the fact that Humans have had a 200,000 year head start.
And we may never know how serious Ken Thompson was when he wrote this paper http://cm.bell-labs.com/who/ken/trust.html
This is quite impressive. It also worked fairly well for that article in Portuguese too (it's just missing the closing thought, but the original article is vague anyway; there's 3-4 paragraphs trying to conclude, but not a unique final thought).

I'd love to see this plugged into tldr.io, so articles on HN could be automatically extracted + summarized -- and later improved by real humans, as needed.

The fact is ConceptNet does not claim to be a general intelligence, so comparing it to a four-year-old is comparing apples to oranges.

typical yes, but if you get something that actually uses the software decoder because the hardware decoder doesn't support it, you'll peak to 100% cpu and choppy playback.

You didn't think the software decoder takes 5% cpu did you ? :)

Thanks. So what does it mean if you are "hellbanned" but the comments are neither offensive nor inappropriate?

Is hellbanning automated, or is it the work of human judgment? Perhaps it is a technical issue that results in [dead] comments?
I was thinking the same thing. Ensemble methods like this scale very well with the number of machines, with moderate efforts of coordination at least.
The training subset for each tree can still be quite large. Note that most of the implementations failed on their 12 GB dataset.

Although I'm a big believer in streaming/online machine learning, it's not necessarily the best solution. There are many cases when batch is the better option, especially for big data. Anything historical, really.
