duncancarroll··on Mediachain enivisions a blockchain-based tool for identifying artists’ work
It's a great idea with a lot of utility, but my question is: How does dispute resolution work? I.e. How do you prevent bad actors from beating the original artist to the punch, and registering someone else's artwork as theirs on the blockchain?
duncancarroll··on The brain is not a computer
My comments from yesterday's thread in /r/Neuropsychology:

While I understand the frustration with the whole Kurzweil camp, this article reads like it was written by an angry high schooler. It also throws the baby out with the bathwater, in that there are clearly valuable analogies to be drawn from computing, as others have mentioned in this thread. My two biggest disagreements:

- "Your brain does not process information": This statement is too broad. How do I do mental math?

- "Memory is not encoded in neurons [as evidenced by a crude drawing of a dollar bill]": Where then does the crude drawing come from?

duncancarroll··on Tiny Farms Raises Seed Round as Cricket Farming Heats Up
It's possible some crickets are less stinky than others. But man, that smell... Shrimp, etc don't stink like that.
duncancarroll··on Tiny Farms Raises Seed Round as Cricket Farming Heats Up
Sure, but I honestly can't think of a seafood product, raw or cooked that smells quite as bad as crickets do. Even when cooked they somehow retain the smell (I accidentally tried a "grashopper" taco once--turned out it was actually crickets--one bite was too much.)
duncancarroll··on Tiny Farms Raises Seed Round as Cricket Farming Heats Up
As someone who once owned geckos and fed them with crickets, the memory of the smell alone is enough to deter me from ever eating any cricket-based product.
duncancarroll··on Comets can't explain weird 'alien megastructure' star after all
+1 for "Funky Star" hypothesis.

This seems just as probable/improbable as any other speculation, including (meme joke) "Aliens."

duncancarroll··on Cruncher: An Implementation of Bret Victor's Scrubbing Calculator
I know, and I don't mean to single you out, it just gets tiresome when the top-voted HN comment always seems to be critical. I felt this post in particular deserved better.

It was even more funny because while I was waiting for the comments to load I was thinking, "This is an awesome tool, but I bet the top comment is going to be some obscure reason not to like it."

duncancarroll··on Cruncher: An Implementation of Bret Victor's Scrubbing Calculator
Very cool! Thanks for sharing!
duncancarroll··on Cruncher: An Implementation of Bret Victor's Scrubbing Calculator
No offense, but clearly no good deed goes unpunished on Hacker News =)

Notwithstanding opinions on the merits or lack thereof of abstracting and visualizing concepts that may or may not help your syntactical understanding of algebra, I want to point out that this is A) a brilliant idea and B) a really cool implementation.

Kudos to the developer who spent the time to implement this, and to Brett for putting the idea forward. I hope this gets traction and is continued to be built upon.

duncancarroll··on To predict the future 1/3 of you need to be crazy
Small correction: It was the 10th man's duty to *disagree with the other 9 and prepare for that outcome.
duncancarroll··on A neuroscientist had his brain scanned for a year and a half
Terrific work! Not presently having time to read the entire paper, I am curious: did you find much of interest in the metabolomic and/or genomic data? Or did MRI prove most fruitful. Also, did you obtain any MRS data?

duncancarroll··on Arne Næss: Recommendations for Public Debate
Arne Naess! Founder of deep ecology. Good to see him posted here, & good rules of thumb for debate. Also good is this chart: https://abagond.files.wordpress.com/2010/08/disagreement-hie...
duncancarroll··on [dead]
Is there a list of grievances anywhere? So far, all I know is that this person fired an employee the community happened to like, and has removed hate-speech subs (why is that a bad thing?). Is there anything of substance that has been done to damage the brand?

I went to this petition hoping there would be a bulleted list of objective criticism, but it's not there. To me this makes the whole argument seem emotionally rather than logically based.

duncancarroll··on Why do buses bunch?
Anyone else learn this from scheduling trains / switches in A-Train? =)
duncancarroll··on Towards Realtime Deformable Worlds: Why Tetrahedra Rule, Voxels Drool
Really interesting article; the videos + audio made it especially fun to read / watch. Impressive that all this came together in about a year and a half!
duncancarroll··on Show HN: Gilded – Add a Cover Charge for Unsolicited Email
I actually really like this concept except for one important detail--the name. "Gilded" sounds elitist. Please don't make people hate me even more than they already will when someone I forgot to add to my VIP list starts getting asked to pay for the privilege of emailing my "gilded" account.

The name here is obv. more important to users than with other apps because it's embedded into the email address. I'd even rather have a nonsensical name than something that makes me sound elitist.

duncancarroll··on Watson in the Wild: Brewery Master
Has there been any pricing information released about the Watson API? I can't seem to find anything but my assumption is that it would not be inexpensive whenever they do start charging for it.
duncancarroll··on The Man Who Quit Money: An Interview with Daniel Suelo
"Money only exists because two or more people believe that it does."

Er.. I get the point he's trying to make here, but I think what he's not seeing is that currencies basically spontaneously emerge out of the necessity of conducting trade. So, sure, you can try to pretend the construct doesn't exist, but you're just closing your eyes to the problem because you don't happen to like it.

duncancarroll··on Meditation Is Garbage Collection for Your Mind
This is so true! And GC is a brilliant metaphor.

Typing this quickly since I'm on a deadline at work, but for those interested in getting started, I set up a quarterly "Meditation Challenge" online group to track progress and keep people motivated by having a group of people and a goal. Myself and people in /r/meditation run it, so it's not a corporate anything, just a public service.

You an add your email and it will notify you when the next challenge starts:

duncancarroll··on The surprising and continuing influence of Swami Vivekananda (2012)
Oops, I got the Amazon link wrong; this is the right one: http://www.amazon.com/Gopi-Krishna/e/B00IPT2UYC/ref=ntt_athr...
duncancarroll··on The surprising and continuing influence of Swami Vivekananda (2012)
That's a legitimate question! Part of the whole problem in this field of study is that there's no widespread agreement on even such basic things; everyone has their own idea and no sound research has been carried out to establish what it is we are even talking about.

I could talk at length on the subject but I couldn't do it any better than Gopi already has; you should check out "The Real Nature of Mystical Experience"

duncancarroll··on The surprising and continuing influence of Swami Vivekananda (2012)
If you're interested in someone who both loves Yoga & meditation, and tends toward a rational bent, you should also check out Gopi Krishna.

http://en.wikipedia.org/wiki/Gopi_Krishna_(yogi)

He was a pretty normal guy living a pretty normal life in the 1900's, and in his 30's through meditation he had a textbook enlightenment experience which resulted in a metamorphosis of sorts that he ultimately came to believe was biological / physiological in nature and could be repeated in others. He's one of the first if not the first person to suggest that what we think of as enlightenment is actually a biological event that the human body can perform given the right triggers, rather than simply a different state of mind or frame of thought. This is a revolutionary idea if you think about it; talk about "hacking the brain". The great thing about him is he's very relatable and not aloof, he kept his job as a government clerk and aside from selling a small handful of books, was clearly not interested in making money off his ideas.

He tried for years to raise interest in the scientific community to study the phenomenon, but of course grant money is hard to come by, and doubly hard if you're doing anything remotely unconventional, so his research foundation never took off and he passed away in I think it was 1981.

A lot of people don't know about him, but they've started putting his books on Kindle so you can go check them out. All of them are extraordinary reads, although I'd start with his prose, and then move to his poetry if you're interested in that.

duncancarroll··on Death Valley National Park: First Observation of Rocks in Motion
Still not quite sure how the trails themselves are formed if the rocks are riding on ice sheets 10's of meters in area, or am I reading this wrong / quickly?

Edit: n/m, it appears the ice sheets are massive and free-of-friction enough to actually push the rocks around. Cool!

duncancarroll··on Orbcomm OG2 Falcon 9 Satellite Launch
Orbcomm, you say? This is all I can think of: http://upload.wikimedia.org/wikipedia/en/a/a9/U.F.Off_-_The_...
duncancarroll··on Show HN: I built an Android live wallpaper with Scala – now it's free
This is pretty impressive work--thanks for sharing!
duncancarroll··on Oculus Rift review: The virtual reality headset will change everything
Did nobody edit this article? It's bizarrely written.

"Gravity and physics say you can’t put a ride an ant Honey, I Shrunk the Kids–style, but who is going to listen to gravity and physics when you can ride an ant..."

duncancarroll··on 100 Days of Meditation
Hey, how do I convert from lux to watts? =D
duncancarroll··on 100 Days of Meditation
I know what you mean. I probably should have called it a "personal challenge."
