jdmitch··on Archaeology: The milk revolution
The article ignored the emergence of lactase persistence in West Africa and Saudi Arabia (where two other hotspots on the map are) but there is more on that in this study:

jdmitch··on Facebook Operations Chief Reveals Open Networking Plan
We want to shoot for all of the things we want in open switches, but you can’t boil the ocean. We want hardware disaggregated from software, and we want to deploy that hardware in production.

I can't decide if this sounds a bit defeatist or is just pragmatic - isn't the goal lofty enough to require the ambition to boil the ocean?

jdmitch··on MIT inventor creates cube robots with no external moving parts
From the video at the bottom "We found out by accident that they were able to jump, we weren't intending for them to do that..."

Maybe the Terminator comparisons were all too prescient...

jdmitch··on Hacker Scouts teaches children Linux, robotics, and welding
Where was this when I was a kid!
jdmitch··on [dead]
The animals are all arranged in poses by the photographer.

...that kind of ruins the haunting photos - I thought they'd just died from looking at the lake!

jdmitch··on Ikea's New Solar Panels: Sunshine Optional, Subsidies Required
It doesn't sound like it is sustainable to have these subsidies for very long:

- At current rates the Feed-in Tariff pays you 14.9p for every kWh you produce, whether you use it or not. The Feed-in Tariff is TAX FREE and RPI Linked.

- Export your excess electricity to the grid and earn an additional 4.6p/kWh.

jdmitch··on Self-Publishing vs. Working with a Traditional Publisher
This article is talking about games, not books... and the distinction here is between keeping all of the costs in-house from production to distribution and publicity. Indie publishing (whether of games or of books) would still likely involve some cost-distribution to the publisher/distributor.
jdmitch··on Sorcerer's Apprentice Syndrome
Let the Fantasia nightmares begin!
jdmitch··on Cancer vaccine begins Phase I clinical trials
50 percent of mice treated with two doses of the vaccine...showed complete tumor regression.

I would have thought clinical trials would require a higher success rate... is it only because it's the last resort and patients would otherwise die anyways?

jdmitch··on Can faith ever be rational?
Perhaps 'rational' is too broad, as it seems the author means rationally probable, rather than rationally definite - we have "faith" in a large number of things that we don't actually see or know personally, but we have rational reason to believe or more likely to be true than not. If I rationally believe it is probable that a knife is holding will cut the bread I want to eat, this requires little faith because if it doesn't I can just grab another knife. When it comes to believing in something intangible like a religion, rational probability may take an individual to one level of certainty based on their experiences which deny or confirm the implications of that belief. However their faith to act further on those implications may be a matter of faith based on the potential risks. the author writes in the full paper:

A person might have faith in God when it comes to giving weekly donations to the poor but lack faith in God when it comes to allowing himself to be martyred.

jdmitch··on Huge water reserve discovered in Kenya
in this follow-on article (http://www.itv.com/news/2013-09-10/potential-significance-of...) there are a few more details on how Alain Gachet discovered the aquifer:

He takes existing satellite, radar and geological maps of the area and layers them on top of each other to create one all-encompassing study of what lies beneath the soil.

jdmitch··on Star Trek and the shiny, boring future
It’s a terrible shame and a real disservice for the years to come when the people we count on to dream are content with IKEA and iPads.
jdmitch··on Scientists may have found a new state of matter
seems to be pretty old news from the original link: http://news.sciencemag.org/physics/2010/12/new-state-matter-...
jdmitch··on Samsung unveils Galaxy Gear smartwatch accessory
I love their verdict on the casio calculator watch The original and the best! :)

jdmitch··on So that’s what I’m going to do
smaller is better :)

Thanks for doing what you do!

maybe game haiku?

jdmitch··on An open source HTML/CSS framework for prototyping native touch applications
The planned 0.2 release is delayed due to little public interest in Clank. -clank blog

Is user interest enough for the OP, or are you looking for other contributors?

jdmitch··on Musk's Hyperloop math doesn't add up
The most important issue in terms of long-term cost-effectiveness is how much it will actually be used, and how much of the time it is actually full. High Speed Rails or any trains for that matter, are plagued by the inefficiency of having to run at a set schedule regardless of how many tickets are sold, and they ultimately don't justify their own existence in most of America. The hyperloop, aside from attracting new people who otherwise wouldn't have considered rail travel, also has the benefit of having smaller capacity and being able to adapt to demand more quickly. With no stops between SF and LA, if there are no passengers at a certain time, you just don't send the vehicle -its that simple.
jdmitch··on Why did I reimplement Jekyll using NoFlo
great post! bad kerning :(
jdmitch··on The most interesting things I've learnt about learning
Face-to-face instruction should focus on practise and exploration, not on learning basic facts.

I don't think face-to-face instruction should focus on practise and exploration any more than it should on learning basic facts. Practise is controlled repetition, and this is probably the easiest thing for a learner to undertake on their own. Exploration is likewise a very personal endeavour - it's always come down to exploring how the concepts are relevant to me, or a specific context I am interested in.

Face-to-face time ('instruction' is not really the right word for it) should focus on collaboration more than anything.

jdmitch··on Amazon launches Amazon Art marketplace
This seems pretty incredible, unless there is something not entirely straightforward about who has actually made them. $1200-$2000 for an original limited edition Salvador Dali or Marc Chagall print, seems like a steal. Maybe I just don't know much about how less rare artworks of well-known artists tend to be priced though...
jdmitch··on Open letter to Sal Khan
I don't think the Khan Academy videos have ever really aspired to be the most pedagogically nuanced videos anyways. It's not necessarily a huge problem for those who are quick learners and have others around them (at home or school) who will correct the inevitable errors (like the one pointed out by the OP). It may become more of a problem for those who are entirely dependent on Khan Academy (or similar online sources) for all of their education, which is not who it was intended for, and there can't be too many who are in that position.

A number of educators do take issue with Khan, but no one else seems to have put the effort in to supplant him rather than simply criticise.

jdmitch··on Skin in the Game as a Required Heuristic for Acting Under Uncertainty
the skin in the game heuristic relates directly to the virtue of being such that the system will not only survive uncertainty, randomness, and volatility but will actually benefit from it.

Doesn't Taleb mean that the 'skin in the game' heuristic will prevent uncertainty, randomness and volatility in the system rather than bring benefit? Within examples such as the 07-08 financial crisis, which he must be referring to indirectly, 'skin in the game' would have meant less risk-taking, therefore reducing volatility. But I can't see how the system would have actually benefited from volatility.

jdmitch··on Growth Hacking Notes
this piece about hacking should give you a good example of aggressive networking.

'aggressive networking' is right, don't some of these tactics get you blocked or reported?

jdmitch··on The Baltic Demographic Disaster
I think that is actually a huge factor, and one of the key obvious things that the OP overlooked. Latvia (and I suspect the whole Baltic region) was at an artificially inflated population peak when the Soviet Union collapsed. It was one of the most economically prosperous areas of the Soviet Union, and had huge Soviet military bases. Retirement on the Baltic coast was the dream for military brass as well as many other Soviets in the 80s. Additionally, the freedom movements and greater autonomy in the second half of the 80s may have attracted others from other Soviet Republics.

Since independence, and particularly recently, Russians (who once made up over half of Latvia's population) have left, and in many cases not been welcome to stay. One of the major tensions in Latvian politics today is the status of Russian Latvians.

With that backdrop (and given the other factors, such as migration to the rest of the EU) it isn't really that surprising that population levels are returning to that of the 60's.

jdmitch··on Against Cynicism: A philosopher's brilliant reasons for living
While I wasn't previously familiar with Sloterdijk, I find it interesting that he takes exactly the opposite value from Christianity as Slavoj Zizek, the other great popular atheist apologist for Christianity (cf. Zizek's The Fragile Absolute: Why the Christian Legacy is Worth Fighting for).

"Sloterdijk’s ideal is not Pauline conversion but Trinitarian 'perichoresis,'"

Unfortunately, I don't think Sloterdijk has understood the theological context of perichoresis which he goes on to define:

"'Perichoresis means that the milieu of the persons is entirely the relationship itself,' he writes, envisioning love as a total mutual absorption."

Perichoresis is literally "mutual interpenetration" and refers to the greek choros and their dances around (peri) each other in interlocking rings in the theatre. In the theological appropriation of this imagery, this has more to do with the depth and interdependence of the relationship than with the "milieu" - though it's not clear what he means by that.

jdmitch··on 'Crack baby' study ends with unexpected but clear result
Hurt's study enrolled only full-term babies so the possible effects of prematurity did not skew the results.

Doesn't this mean that their selection sample effectively excluded any babies that had a noticeable physical reaction (other than having cocaine in their system) to the effect of their mothers' cocaine use?
