arjn··on “No-CAPTCHA” reCAPTCHA
Here is a key difference from prior CAPTCHA services :

"reCAPTCHA offers more than just spam protection. Every time our CAPTCHAs are solved, that human effort helps digitize text, annotate images, and build machine learning datasets. This in turn helps preserve books, improve maps, and solve hard AI problems. "

They're using captchas to solve text analysis and digitizing problems.

arjn··on Alibaba's Singles' Day sales exceed predictions at $9.3B
Also one of the most polluted places on earth.
arjn··on SpaceshipTwo crashes shortly after Mojave test flight
Totall agree. These people are the modern day seafarers. Heading out into unknown waters.
arjn··on SpaceshipTwo crashes shortly after Mojave test flight
Its very sad but inevitable. At this cutting edge of technology and human endeavour, accidents are bound to happen.
arjn··on The day UFOs stopped play
I wasnt objecting to your intelligence theory. Its perfectly ok to assume there may be intelligences in the universe far superior to ours. I was referring to your comment on the "common objections to UFOs".
arjn··on The day UFOs stopped play
"Simply impossible" is not correct. "Highly unlikely" or "Highly improbable" is the right phrase to use.
arjn··on Mysterious US spaceplane returns to Earth
I'm wondering if this could be a vehicle not just for reconnaissance but also delivering a kinetic energy projectile from space ? (Note - i'm merely speculating)

arjn··on Nexus Player
No, it doesnt.
arjn··on Lapham's Quarterly
I've been a reader of Lapham's Quarterly for about 2 years now. So much better than watching TV and crappy movies.

Its kind of meant to be a starting point for readers to find something interesting and follow it through in more detail.

Similar to a curated list of topics with short bits of content to pique interest.

I love it.

arjn··on The Unix System: Making Computers Easier to Use (1982) [video]
Wonderful video. There are a few more intersting ones on that website (AT&T's archives).

Thanks for posting this.

arjn··on When Keurig fights “coffee pirates,” who loses? Loyal consumers
I have the primitive coffee brewing system too .... its fantastic :-)
arjn··on Poll: How long could you survive without income?
Can you post some more details on your situation - location, jobtype etc ?
arjn··on The Deadly Stupidities Around Ebola
And therefore it must be because the US did something, right ?
arjn··on The Last Day of Microsoft Research in Silicon Valley
So is there any inside info on whats going on ? I despair that corporate funded computer science and engineering research is on the decline.
arjn··on Why did science make little real progress in Europe in the Middle Ages?
The middle ages were a period of great turmoil in Europe, so even if there were scientific, literary or artistic advances they could easily have been destroyed. We only know what we know from stuff that has survived the turmoil and the following thousand or so years.

Also, I'm very surprised the quora article did not even mention the plague and the effect it had in those days.

arjn··on Navdy
Isnt this a re-post ? It was a bad idea then and its a bad idea now. Distractions while driving are potentially dangerous.
arjn··on The elephant that flew
Sad ending. However its heartening that someone tried to save the baby elephant. The world needs to do so much more to protect wildlife. It seems things have gotten so much worse over the last decade or two.
arjn··on Al-Jazari
Maimonides was Jewish.
arjn··on The Man Behind the World's Smallest V-12 Engine [video]
I've seen this before, this and another, younger Italian guy. Excellent and impressive display of mechanical skill.
arjn··on Al-Jazari
Interesting, thanks for posting. I new about semi-automatons created for the Turkish rulers for entertainment but not about Al Jazari.

I would like to add that the Persian, Arab and Turkish empires benefited greatly from Chinese, Indian, Roman and Greek math, technology and science that had been developed much earlier. This frequently gets glossed over or completely ignored.

arjn··on Evidence Grows That Online Social Networks Have Negative Effects
I've long suspected this and have been off social networks since 2007/08. Have taken a lot of grief from friends about it though.
arjn··on Craft Coffee’s Coffee DNA Project (YC S14)
Portland has a lot more than Stumptown and Heart. Spella, Coava, Extracto, Clive, Oblique .... and more.
arjn··on Student’s six-foot water and solar-powered lens purifies polluted water
I've seen this approach tried before - it has problems :

"Due to the sun’s movement throughout the day, Henry needs to repeatedly shift the container to match the focal point. "

arjn··on The Strange and Curious Tale of the Last True Hermit
Very nice article and writing - and a great subject.

To wander the woods all day, read when you want,

To be free of all connections, to not even need a name. There is something to it.

Oh ..and Rudyard Kipling ... wonderful.

arjn··on Is Sublime still alive?
What about a Kickstarter/Indiegogo type campaign to pay the developer to opensource it ?
arjn··on Craft Coffee’s Coffee DNA Project (YC S14)
For good coffee - go to Portland, Oregon.

I've had some of the best coffee I've ever had in North America there.

arjn··on Using a Tactic Unseen in a Century, Countries Cordon Off Ebola-Racked Areas
I recall reading about how they did this back during the plague days in France. Cordon off an affected town and don't let anyone in our out.
arjn··on The War Photo No One Would Publish
http://en.wikipedia.org/wiki/Highway_of_Death
arjn··on The War Photo No One Would Publish
I've seen this photo before. If I recall correctly it was from a story or article called "Highway of Death" or something like that.

Tragic and gruesome.

arjn··on The US Intelligence Community has a Third Leaker
When an organization gets too big, it is statistically likely there will be leaks.

I think the US has forgotten or willfully ignored the lessons learned from the past 100 years of espionage.
