acro··on Earth's organisms developed via evolution. What if the cosmos did, too?
Maybe you mean Orbital resonance: https://en.wikipedia.org/wiki/Orbital_resonance
acro··on BMW shares AI tools used in production
Here's a nice video of the YoloV3 (which these tools are using) in action from the author of YoloV3 (Joseph Redmon): https://www.youtube.com/watch?v=MPU2HistivI
acro··on The Neural Network Zoo (2016)
To me the DCN picture looks ok, in convolution layer nodes receive input only from small area of the previous layer, in general this is true for convolution layers (kernels) and pooling layers. After that it has couple of fully connected layers where the connections go from every node to every node. Or have I misunderstood something in your comment?
acro··on Jeff Bezos Is Just $5B Away from Being the World's Richest Person
Revenue is the top line, net profit is the bottom line. There are many ways to get money out of a company which come before the net profit line in an income statement. Companies can also spin off parts of them in many different ways. The only thing I'm stating that P/E is often the wrong number to look at in a company.

An investor can get value from a company in other ways than net profit. For instance share buybacks, dividends, mergers and acquisitions, companies can pay back capital. P/E ratio is just one very simple number which is not applicable to all situations. For example REITs have often very high P/E because most of their profit is distributed as dividends. Using P/E to try to value Amazon is in my opinion misguided.
acro··on How much do indie PC devs make, anyways?
Yes, I have played it. I think it's a good game. It has good controls, good music, nice "flow" to the game. It's not very deep game, but fun to play nevertheless. I heard someone describe it as the best restaurant simulator game available.

There are many people who have at least that sum of money and they appear in public all the time. I have heard this same thing about "him surely getting robbed or killed" several times now, it feels always a bit odd to me.
acro··on Ray Kurzweil is wrong: The Singularity is not near
I stand corrected, no official even game wins against professionals. Maybe I remember seeing unofficial games on KGS. The progress is impressive anyway, just a while ago the best computer programs were around 8-10 kyu level.
acro··on Ray Kurzweil is wrong: The Singularity is not near
What happens when performance approaches infinity? Many AI problems have been solved because there is now simply more processing power available. For example computer Go using Monte Carlo methods. Just a couple of years ago people thought it was impossible for computers to beat human professionals.
acro··on Ray Kurzweil is wrong: The Singularity is not near
Still, the performance of computers is increasing exponentially. The arguments in this article seemed a bit weak.

acro··on Why does Sweden have so many billionaires?
Finland was not "Russian-held" in WWII.
acro··on New banner ads push actual Google results to bottom 12% of the screen
DuckDuckGo has ads.

acro··on Financing Investment In A World Without Maturity Transformation
Usually it's the other way around. By law normal investors have to be educated about all possible risks involved. Accredited investors don't need such information since they supposedly know those things already.
acro··on The size of the shadow banking system estimated according to power law
Banks are generally regulated, they have to have certain amount of assets to work. They cannot have the same distribution as normal companies do.
acro··on Why discussions on cyber snooping have been so painful for us
But you certainly are protected by the Finnish constitution. At the start it says like this: "All humans are equal in the eyes of the law".
acro··on Texas teen makes violent joke during video game, is jailed
It is completely absurd that making a sarcastic comment can be a crime that means a decade in prison. Shouldn't there be some common sense included in the justice system? Here in Finland there have been lately some similar cases, and in all of them as far as I know there was some simple investigation about the real motives but no charges and no jail time.
acro··on Why Snowden Asked Visitors in Hong Kong to Refrigerate Their Phones
Maybe phones are not so sensitive to condensation. At least here in Finland phones seem to work fine, despite outside temperatures being similar or below to what is found in a fridge most of the year. People move phones in and out of buildings all the time with large temperature differences between. I don't think I have heard anyone breaking a phone because of condensation here.
acro··on The day Steve Jobs dissed me in a keynote (2010)
It was submitted 945 days ago, if I remember correctly there is a time limit.
acro··on Thrown Off a United Airlines Flight for Taking Pictures
Isn't taking photos in public place like a train station completely legal?
acro··on The Value of Time
There is more to life than optimizing everything based on cost. That walk from the more distant hotel is healthy for you, and you get to enjoy the scenery. Sometimes it's good to think of time as having monetary value because it gives you perspective, but also sometimes it's good to forget it and actually enjoy life.
acro··on Dental X-Rays linked to Brain Tumors
Some perspective from XKCD: http://xkcd.com/radiation/
acro··on One Word Reviews: More informative than Metacritic, shorter than Penny-Arcade
Was not really disappointed :) I do think it's a good idea, and feel that the site would add real value. Maybe later show more reviews per game when you have more reviews?
acro··on One Word Reviews: More informative than Metacritic, shorter than Penny-Arcade
I like the idea. But tried to give review "Immersive" to Skyrim and the app told me I can't give review like that because they don't have the word in database. What's with that?
acro··on Your Life Is an Algorithm, Your Brain Is an Operating System
Nick Bostrom wrote a paper about living in virtual reality in 2003. At least to me his writing was really interesting. http://www.simulation-argument.com/
acro··on [dead]
I hope someone is taking care of him? Just wondering because many mental illnesses can be handled very well with proper medication and therapy. He is so talented he could do great things with the illness handled properly.
acro··on Ask HN: Is there a WGET that also works with paginated articles
How would the utility know for sure which link will be for the next page?
acro··on Show HN: Garden Madness, a flowery HTML5 game
Seems to work quite nicely on HTC Desire with Android 2.2.
acro··on On Working Remotely
And it sometimes seems very difficult to explain to the management types that adding people to the project will not make it go any faster.
acro··on Android Passes iPhone Web Traffic In U.S.
Its a bit vague, would be nice to know what this is based on.
acro··on Ask HN: Back problems
This is correct. Even though intuitively it might seem unlikely that hamstrings have anything to do with lower back pain, but they really are linked. There are also other stretches and exercises which help.
