Your own personal robot at home?
Hi,

We love robots but the advanced robots used in Universities and Institutes, like Keepon or NAO, are way too expensive. So we have to do with the cheap toy robots like Furby, Fijit Friends or MyKeepon, which can hardly do anything. So how can we benefit from the useful features of advanced robotics?

That is why we built our own robot platform to show that a sophisticated robot can still be affordable.

We focus on young children because robots and kids go very well together and they address a real need. The robot acts like a peer to play tangible games with. In the meantime their parents can take care of household chores, administration, etcetera, while the robot occupies their children. They do not have to feel bad about it as the robot also supports their children's development.

To give you an idea of what we currently have, please have a look at these two movies of our prototypes:
http://www.youtube.com/watch?v=iUVgOZonpq0 (a toddler showing emotion cards mimicked by the robot)
https://www.youtube.com/watch?v=QTMLvKFUYiU (the robot dancing to the music. note that this video isn't visible on mobile devices)
You can also have a look at http://www.wittyworx.com/IXIPlay.html for more detailed information on our current concept.

During discussions with many people we noticed interest in having such a robot for themselves. So what about you? What would you do with such a robot? Which Apps would you think of? We are really curious about what you think of it and would love to get some feedback on our concept.

Thanks.
Isn't it damn obvious that you shouldn't associate your brand with subjects that carry negative emotional load, with suicide being a prime example? Anchoring and all that.

Thanks :). I had to build an installer to check that you have Mono installed by running a "which mono" command and displays an error/info message otherwise. I could provide a separate download that doesn't but it's more work and my hands are already more than full so for now, I'm afraid that'll have to do :)
When did CO2 become water? The ad states 100% water emissions, yet their site has listed that the car produces 139 g/km of CO2.
From TFA:

"This finding points to a promising target for new drug development because it suggests that mimicking sleep deprivation chemically may offer the antidepressant benefits without the unwanted side effects of actually skipping sleep."

So no, they aren't recommending sleep deprivation as a method to combat depression. It has, however, given them other lines of research to follow.
Heh, I didnt know about the automatic feeding, I always get annoyed that these ATM's are slow and old.
However, if they can e.g. allow a black hat access to the seriously classified stuff, they need the high clearance. Be it a Marine "security guard", the janitor, from top to bottom they need to be as trustworthy as we can determine.
As much as I love the idea of this happening, if we are talking about such tiny variations, it's just as likely that erosion (air, water, pottery mud) would've wiped these tiny variations out.

> Imagine someday where many people own their own personal satellite.

Nice thought, but (unless the satellite is in geostationary orbit, very expensive) it won't work. Imagine having your own personal satellite that is only accessible for perhaps two short periods in 24 hours (for a mid-northern latitude location).

Better to have a subscription to a system with dozens of shared satellites in random orbits, available 24-7.
make-hash-table is an abomination. Thanks for this.
This article is fascinating but as someone who doesn't know much about this discipline, I'm hoping for someone to clarify my confusion:

In the article, it states that our core has temperatures comprable to that of the sun. However, the sun is 93 million miles away while our core seems to only be approximately 4000 miles deep. Shouldn't the Earth be hotter than or are there just so many layers that the heat decreases at such a fast rate as it approaches the surface?
Some call it boxy, others call it low-poly or "Minecraft-like". No generic name that I know of.
I don't assume perfect information; all economic activity bears risk and your choices are guided by your risk tolerance.

Not when you're drunk they aren't. It's arguable that a choice was being made. Secondly, if there isn't perfect information, it's not possible to accurately gauge the risk.

Sometimes, you make a bad choice and suffer the consequences.

And we don't, as a society, think it's reasonable to have people on edge about making the right choices all the time, so we seek to mitigate those consequences as a group.

"Eliminating choices doesn't eliminate those consequences, it simply forces you to either adjust your risk tolerance against your will or engage in even riskier activity."

OK, cool, now how terribly awful a transgression is it to force (OMG!) people to call a cab instead of stumbling into one? It's not. And that's what people do now.

And no, I don't agree with your estimation. It is not impossible to tell if crime rate has dropped, it is not likely that crimes are going unreported due to the taxi 'black market' and it's relatively easy to determine if the alternatives are safer, and they have been.

"safety may not be the only priority people have. It is entirely based on your own subjective risk tolerance."

Sure, we can agree on that, and democratically we as a society have agreed that some risks are intolerable even if (gasp!) some people have to get the bus or pay an extra 50p for a cab. So we make laws.

Come on, stop messing around, you know this is the bit you really object to, society deciding amongst itself that your unregulated business is not wanted and cannot be run here. Yes, it is the government (or the people) inflicting their will on others in the interests of safety and progress. You'll never persuade me this is wrong.

I do this as well, mostly because I do a lot of third world traveling and it's easy to get your card cloned. I only keep $500 in the checking account linked to my debit card, and the rest in a savings account that I can transfer money from instantly. I did have my card cloned once and this technique saved many thousands of dollars from being spent. I would have recovered it all eventually but it takes weeks and it would be a disaster while on the road.
:)

If you must know, I was glancing over the headlines while eating breakfast, pondering how to get a colleague to stop being so theoretical and actually try putting some of their ideas into action. (A very smart person who, as you may have guessed, reads tons of stuff everyday.)

To mutilate an old saying: In theory, reading about something and doing something are the same thing. In practice, they're not.

(edit: P.S. There was a time when I read everything I could get my hands on. I eventually learned that I much prefer to be effective, not smart.)

This is really all that matters. The only thing I'd add is that for you to be able to accurately gauge the success of a given campaign requires that you understand what the lifetime value (LTV) of a customer is. If, for example, you don't know your LTV, then you can make critical errors. Let's say that you spend $100 on a campaign and get 12 signups and $50 immediate money. On the surface, it appears this is a bad campaign - after all, you've lost $50. But if the LTV of each member is $12.50 and you've added 12 new members, you're LTV amount is actually $150 thus making this a $50 profit. Sure, maybe it takes six weeks or five years to get that money but, if your LTV number is close to accurate, then you can rest easy knowing that you should renew the ad campaign.
Although it's admittedly difficult when the higher temperatures are hundreds or thousands of kilometers away, geothermal power plants do in fact harness that.
Form follows function doesn't have to result in minimalism or flatness.

Gradients, drop shadows, bevels and other 3D effects function as visual cues, and can help a user figure out the hierarchy, order and function of elements in a 2D design. They're not extraneous, at least not when used properly.
i actually like the ad.
In reality it is simply not possible to create such gains on average. SAT score is still a very good predictor of future academic performance.

"Does test preparation help improve student performance on the SAT and ACT? For students that have taken the test before and would like to boost their scores, coaching seems to help, but by a rather small amount. After controlling for group differences, the average coaching boost on the math section of the SAT is 14 to 15 points. The boost is smaller on the verbal section of the test, just 6 to 8 points. The combined effect of coaching on the SAT for the NELS sample is about 20 points."

These are confirmed exoplanets, totalling 872 so far. Kepler and other missions have found probably tens of thousands more planets that are in unconfirmed status and will take years to confirm. If I may speculate, and take SpaceX and Planetary Resources to be successful 10 years out, we might be able to build absolutely astonishingly large telescopes to resolve continent-scale features on exoplanets - and have discovered and mapped millions of them in the Milky Way.

I don't think that's good advice and leads to some very short term thinking.

Reading only the stuff that you must in order to not get fired is tantamount to doing to bare minimum. Having a sciolistic knowledge about many topics is helpful when coming up with new ideas (and more importantly, knowing where to look when you need to do a deep dive), as well as making you a well-rounded person.
Nobody in this thread has claimed that C was unreadable, and now these non-present people are already being divided into groups. And whereas the Ruby crowd is loud, Python programmers have extensive knowledge of other language. Can we please not form artificial factions?

Businesses are run by human beings, so while businesses themselves may be amoral, people making the decisions on direction of the business are not. Or at least one would hope that is the case. That isn't to say there is no place for regulation, but assuming without regulation business should be expected to run amuck is a bit cynical.

Thanks for the quick reply. It's fine, I just wondered, since most "games" don't ask for these permissions, only annoying things like Adobe Flash wants it ;)
I like EVE in some respects, but this game is built specifically, and only, for oldplayers. Everything added is for old players, if you want to do anything interesting you'll need to buy at least a year of subscriptions and religiously log on to train your character.

The way eve metes out rewards is just completely hostile to some people, (ie. me).

EVE online: "Boy I sure wish I was able to do that, that sure looks like fun"

i recommend not playing.
They're comparing the heat of Earth's core to the surface of the sun, not the core of the sun.
Google Screws Facebook Home, Requires Apps To Be Updated via Play Store
The sun heats the earth surface through radiative heating, while the core is well insulated by the mantle and crust. Although they may have similar temperatures, the power output of the sun is certainly larger.
Honestly, I'm not interested in providing details. The parties involved have already kissed and made up (for the most part), and it serves nothing for me to prove myself on HN. Suffice to say, I took, and still take, the position that we each have a finite amount of political capital and goodwill that we can spend, and that it is more advantageous for everyone to spend it on building instead of destroying. There will always be differences of opinion on what is building vs. destroying, though, and there will always be room for poor communication to confuse the matter for all parties involved. Especially in the tech community, as I'm sure you can imagine :)
> this is complete bullshit. Lack of sleep makes (my) depression worse.

Science isn't usually about the experiences of individuals, it's about the experiences of populations. This effect isn't true for each individual in the population.

Can technology reduce our need to sleep?
couple thoughts.

1. isnt this small enough to look like space debris, and maybe dangerous?

2. "The mobile phones are designed to be thrown around the room and for people to drop them in water. They're really robust bits of technology," -- i'm not sure how this physical durability has any bearing on its performance in near absolute-zero temps and in the radiation of space without being using radiation hardened silicon...not to mention that it would never be subjected to any of the things described.
All a matter of taste, I guess. We've seen good results with it, as have plenty of other people. It's easy to overdo it, but 4-5 helpful emails spread out over 30 days isn't too much I think. This is assuming the emails actually are helpful and not just an annoyance.

A lot of recent tools like Intercom and GetVero and Customer.io can help make this even smarter by emailing about specific abandoned tasks, different emails to those who aren't engaged at all, or not emailing someone who is fully engaged.

If I am not mistaken Iceland uses geothermal to a large extent and is very successful in doing so.
It's important to note the fact that the heat in the core does not exist in isolation of other fields. The Earth is a dynamo system, and the energy in the core is connected to the planet's magnetic field, the energy bound up in its orbit around the sun, and its gravitational field.
Just be glad he took it before someone came along with omellete.ly, a new service that brings social to commandline arguments.

On a serious note, I think it's a smart move to use a name like this, or something like Carrotjuice.js or MochaDB. Names are important and so are the trends that accompany them.

The right way to do "education selection" is to pick the best students from your applicant pool. I don't see what would be wrong with that method.

Are Negative Twitter Messages Contagious?
Actually, that's not only a fairly weakly implied argumentum ad populum, as it doesn't actually argue that the number of ignorant people are small or the number of non-ignorant people are large (though the use of "only" might imply that.)

"The only people who disagree with this statement are people who are simply not informed" is more directly argumentum ad hominem, and, particularly, abusive ad hominem.

http://courses.csusm.edu/fallacies/abusive.htm

Its also, simultaneously, petitio principii since claiming that disagreement with an argument can only be due to ignorance to support an argument is equivalent to claiming that the argument is true to support the argument.
Chernobyl-style designs have been known to be a less safe design for as long as they have been around. They are weapons-production reactors scaled up for power production, without any of the design changes to add inherent safety that were made for even 1950s-era Western designs. Chernobyl belongs in a category all by itself for that reason.

TMI was certainly an economic issue, but it was never a public health concern, even in the middle of the meltdown. In fact TMI was a validation of the public safety concept of nuclear power plant containment design; despite suffering a full as-bad-as-it-gets meltdown there was only a minimal release of radioactive gases to the environment.

As far as Fukushima, there were actually two different sites, Dai-ichi and Dai-ni. The Dai-ni reactors were a very slight spec bump up from the Dai-ichi reactors due to being started later. Both sites suffered the same earthquake & tsunami; all of the operational Dai-ichi reactors melted down, none of the operational Dai-ni reactors suffered damage. The disasters were beyond design basis for both.

So even 40-50 years ago they were continuing to make design improvements to increase the safety margin of nuclear power to account for "unknown unknowns".

Meanwhile even today coal plants pump carcinogenic exhaust directly to atmosphere and people judge it as an acceptable tradeoff because the damage is constant.
> Previously, elisp package authors would try to make their code self-contained.

And I fervently hope that does not change. Moving Emacs to the world of Gems/Bundler or Maven, where every package depends on two dozen half-assed libraries (each of which transitively use at least two dozen more), and where everything breaks all the time because someone decided to "upgrade" to the JSON parser in vogue this week, hardly strikes me as an improvement.
I'll admit that those cities are not for everyone, but they are irreplaceable for most people that live in them. If you make enough money to live in one of those cities, the lifestyle cannot be replicated outside of those cities.

What about Chicago? Great city, not as expensive; problem is, not much VC money. I would rather the worst thing about where I live be called "January" than have it be called "rent".

VCs can choose where they want to live, most of them choose tier 1 cities. Talent also chooses tier 1 cities so the collocation benefits everyone.

Talent doesn't get as much "choice" as HN likes to believe. Sure, good programmers get solicitations for jobs all the time, but often that's just an invitation to waste time on a phone screen, spend six hours on a code test (because you actually care about doing things right) and then get rejected because your choice of language (for the test) fell on the wrong side of that company's ever-shifting internal language wars. Or it's an invitation to work at some startup with shitty cargo-cult culture that'll fire you at 4 months with no severance if you don't go to the strip club with the other brogrammers. Good jobs are goddamn rare and hard to find no matter who you are.

Talent should have the kind of leverage that HN believes it does, but right now, 90+ percent of talented people are poors who still need to adapt to bosses and market trends and landlords.
the availability of energy to the individual almost exactly correlates with economic growth

A corollary might be that the more energy available per capita, the greater the environmental footprint of per capita. E.g. the McMansions of the megasprawl: rolling hills of former farmland are graded and leveled off, enormous balloon-like, energy inefficient stick frame houses pop up, and twice a day their inhabitants wait in lines of SUVs on the clogged roads between the exurbs and the suburban office parks. The entire enterprise is completely dependent on vast quantities of energy being available to participants in the system. People are comfortable in their SUVs and McMansions, and aspire to this lifestyle. But the environmental footprint per capita is enormous. Without some penalty for the external costs (which are long latency and hard to measure), there is nothing to slow the spread of this pattern of economic development.

In this light, when you say:

Energy very well may be the 20th century's internet. The more everybody has it, the better off we all are.

I suspect it is more like an upside-down U-shaped curve. People are indeed better off when we have sufficient energy per capita, but when we have a massive superabundance of energy, we negatively affect our environment to the point that real consequences start to kick in. Unfortunately, it is hard to know where we are on that upside-down U, and it is hard (impossible?) to distinguish overwrought hand-wringing about impending environmental doom from the real thing, until the real thing has started to have obvious, severe, and sustained effects.

I think it's pretty clear that the email that was sent out was not written in the way that it should have been, and that they may have misjudged both the source of the friction they are encountering and the public sentiment about such regulations.

We're sort of arguing past eachother on the other point. If we agree that Uber isn't out to rip people off and their customers like the way that they do business, why should they need to change? If you acknowledge that the changes required are superficial, why are they required?

And based on the way in which Uber is marketed, you're either completely unfamiliar with the service or you're being more than a little disingenuous when you suggest that a yellow license plate wouldn't affect their business. Part of what they offer is the appearance at your destination of having been delivered by a private driver.

I noticed that facebook backtracked on their search bar. When it first launched it was completely non-obvious that it was a text input. A few weeks later they added a negative emboss effect. I agree, it's a nice style, but I think we'll see it settling on a middle ground regarding 3D effects on UI elements. I also think some of the more extreme proponents of the style may be younger designers that haven't already been through several of these cycles. :)

I'm afraid there are many things wrong with your model of how heat works. However a simple factor is that the surface of the sun is ~10000 times larger than the surface of the earth.
But Apple doesn't give away free stuff at WWDC. It's also much more expensive than Google I/O. It seems most likely that there are just a lot of developers who want to go and a limited number of tickets. I haven't been but it seems like it's still a developer focused event to me.

I was thinking of something very similar the other day but in regards to bitcoins. They are very volatile at this stage and whenever they're in the public eye they either seem to increase or decrease in value. Perhaps somebody could perform a study as to a relation between the volume of bitcoin related search terms and it's market value.
