Title should indicate this is from 2009.
jonmc12··on The Distribution of Users’ Computer Skills: Worse Than You Think
I analyzed technology proficiency level vs adult literacy level. Listing the equivalent literacy level with relatively equal % of population. ie, level 3 proficiency is 5% of population; above a college reading level is 5% of adult population:

  Cant use computers ~ Under 4th Grade level including illiterate
  Below level 1 ~ 4-6th grade reading level
  Level 1 ~ 6-10th grade reading level
  Level 2 ~ 10th-college reading level
  Level 3 ~ College+ reading level

jonmc12··on 102M dead California trees 'unprecedented in our modern history'
Was curious how this drought compared to direct human impact on trees, quickly mashed together some facts.

There just over 400B trees live around the world, 7.3B in California. Thats 1.8% of estimated world tree population vs holding 0.5% of people population.

301M of 4.9B (6%) trees died in Texas drought of 2011. Drought in California currently accounts for 102M (1.4%) of trees in the state dying.

Also note California has about 1 tree per person in the world. The worst famine in 150 yrs would kill 30M humans / year if it happened today. This considers the % of human deaths / year by famine of 1876-1879 as a benchmark. The article would imply 72M trees dying / year per drought in California. Not sure how comparable that is given different lifespan / reproduction rates, but kinda interesting.

Worldwide people cut down 15 billion trees each year. Maybe 7B for fuel, 6.5B for paper/etc and 1.5B for lumber. If this was distributed equally (which its probably not in reality), that would be equivalent of 274M trees cut down by humans in California / yr.

The global tree count has fallen by 46% since the beginning of human civilization.

jonmc12··on Soylent halts sales of its powder as customers keep getting sick
I'm not sure the reports say its contamination. Its possible the powder is just incompatible with the digestive system of some people in same way as, say, leafy vegetables or carrageenan affect some people's digestion but not others.

Soylent may be recalling because they don't want to be liable in the _possibility_ of contamination. However, over time, they may find they can make the best product that is compatible with some digestive systems but not others - put a warning on product accordingly.

Cheap, accurate testing of foods for compatibility with a broad range of nutrient absorption rates and microbiomes would be key in engineering foods for everyone. But right now it would just make your food really expensive to the extent its even possible.

jonmc12··on China’s plan to organize its society relies on ‘big data’ to rate everyone
All western reporting about Sesame Credit has focused on privacy. Has there been any objective analysis on projected economic impact of the system?
jonmc12··on What I’ve learned from seeing 20k company pitches
This study from DocSend in June '15 claims the average seed round is raised in 12 weeks after contacting 58 investors. https://techcrunch.com/2015/06/08/lessons-from-a-study-of-pe...

Conditions for raising seed are a bit tougher today, but even in 2015 contacting 100 investors not outside of norm.

jonmc12··on Interoceptive Ability Predicts Survival on a London Trading Floor
You might like Craig's paper "Interoception and Emotion: A Neuroanitomical Perspective" https://books.google.com.au/books?id=DFK1QwlrOUAC&pg=PA272&h...

He presents evidence that primate emotion evolved from interceptive awareness - goes into fascinating detail about what we know of the underlying, homeostatic, neuroanitomical structures and their evolution.

jonmc12··on It’s time to bring more realistic models of human behaviour into economic policy
I've thought China's Sesame Credit system could be interesting in this direction. I know there are some dystopian perspectives on the program. At the same time, consider how much they can learn about consumer behaviors from the aggregated data. And, they can even control this behavior to some degree through gaming mechanics (compulsion loops / social impact).

I don't know much about economics, but it seems this kind of environment (a national-scale, economic video game) could provide a mass of data to inform the 10 suggestions from the author. "practice based on plausible myths" - the opposite of this is practice based on meaningful, real-time data about economic actors, right? Would be very curious of an economists opinion of the role of such a system..

jonmc12··on Human collective intelligence as distributed Bayesian inference
Cool paper! learned a lot about shared beliefs. But I was asking myself "why is 50k traders using similar trading patterns an example of collective intelligence"? I expected an example of a collective accomplishing a group goal as opposed to optimizing individual ability to accomplish goals.

Noted in first paragraph: "we still lack a coherent formal perspective on what human collective intelligence actually is". But, why not reference the closest definition or propose your own rigorous definition of collective intelligence to ground assumptions in the paper?

For instance, in 2007 Legg and Hutter presented a paper, "A Definition of Machine Intelligence" (http://arxiv.org/pdf/0712.3329v1.pdf) which inventoried existing definitions of machine intelligence and suggested their own definition. Seems like these definitional papers would be the starting point for presenting research on any kind of intelligence. Do you see meaningful work in this direction regarding defining collection intelligence?

jonmc12··on All Olympic gold medal winners in the 100m sprint compared in one race
Was wondering why the 1896 time of 12s was so slow - found this pic of the race - https://www.olympic.org/news/speed-merchant-burke-shines-in-.... Running surface, shoes, starting blocks.. exactly. Today there are 8th graders that can run faster than 12s 100M.
jonmc12··on Bullet journal: A simple productivity system that just uses pen and paper
From a workflow perspective, this is basically a practical tickler system (but also integrates notes/collections). Ticklers can be very helpful for removing anxiety about things falling through the cracks, but requires staying in the habit or they become useless. Another once popular system was 43 folders.

imo, the major innovation of GTD and related systems is the inclusion of context beyond do/due dates - specifically the notion of resource availability and alignment towards explicit long-term goals. Done right, this can bring clarity to 'next action' in a way that decreases the incremental cognitive load to select a task to complete - hypothetically making it easier to act in a state of flow and stay in the habit.

Everyone's different, and if any system works for a while thats a win. If you talk to a productivity coach / trainer they will probably share experience that the GTD-type systems have the best impact on busy professionals long-term. When someone figures out how to remove the cognitive overhead of both organization and task selection in a contextual todo-list, I believe its going to change the way many people work.

jonmc12··on Grandparents raising children is in line with human biology
In a recent article "Why Aging isn't Inevitable" (http://nautil.us/issue/36/aging/why-aging-isnt-inevitable), the author suggested that the the "Grandmother Hypothesis" sounds reasonable, "but a number of demographic researchers have found that when they do the numbers, it’s hard to make it work".

He suggests an alternate theory: "An older, “retired” segment of the population, we argued, serves to keep the population stable over cycles of feast and famine."

jonmc12··on The State of Meteor Part 1: What Went Wrong
> Routing is solved by community packages

Its a bit awkward in places. Like if you want to receive a server-side web-hook, Iron Router is really the only way to go. But, lets say you have an Angular client, Iron Router can't be disabled on client when being used on the server. Now you have to hack for Iron Router and Angular UI router to play together nicely - using 2 routers on client because you want to receive server-side webhooks is obviously not ideal. But, at the same time both the community and the roadmap are coming together to make solutions workable before being fully 'solved', imo.

jonmc12··on Social media encourages us to follow those we envy
In a lot of ways I agree, but change doesn't come from attacking people. "Don't hate the player, hate the game" - we live in a place where we don't yet draw clear lines for capitalistic behavior or how it might affect the exploitation of our environment, our friendships, or our life-saving drugs. I'd suggest you help facilitate change by suggesting systemic improvements to how these economic behaviors could evolve and evangelizing ideas in that direction.
jonmc12··on 15B More Reasons to Worry About Facebook (2007)
Pretty amazing, DST's $200M @ $10B valuation came 20 months after the AllThingsD article. From http://techcrunch.com/2009/05/26/mark-zuckerberg-and-yuri-mi... - 'just doing our math':

"MA: You’re comfortable with the $10B valuation?

YM: Absolutely. And, you know, I can repeat the reasons why. Basically, I think they have a very unique perspective on social network monetization, that other investors don’t necessarily see. You see how social networks have been monetized in our part of the world, and we’re just doing our math and coming up with numbers that we feel very comfortable with going forward. We don’t really value this business on (fee?) basis 2009 but rather on a longer term, based again on our experience, and we’re very confident that, you know, those numbers can be achieved."

jonmc12··on Is there a simple algorithm for intelligence?
The author discusses concepts around intelligence without articulating what definition of intelligence he is adopting. When he discusses the innovation in understanding planetary motion, or chemical substances, it represents examples of where scientists could place observed data amongst a common frame of reference (ie, a meaningful definition to contextualizes observation leads the way to a theory which explains the data).

A more meaningful direction for article, imo, would have been to adopt a concrete definition of intelligence, and then talk about how ferrets, chimps, babies and adults fall on this continuum. Perhaps, connectomics, molecular biology, psychology or neuro-anatomy help us approximate the 'atomic number', giving us the opportunity to speculate about the underlying equivalent of quantum mechanics.

Like the article states, evidence is lacking, and we're somewhere between 1-100 nobel prizes away. But, the power of a concrete definition helps point to what we know we don't know, and discussion about whether the definition of intelligence itself needs to be re-framed to answer a question like this.

jonmc12··on Ask HN: What are the greatest discoveries in the last few years?
I thought the discovery of the quantity of distinct populations (~5k currently) and densities (relatively even) of upper-ocean viruses was perhaps an under-rated discovery that could lead to more advanced understanding of both the evolution of cellular organisms on earth and our current ecosystem. https://www.quantamagazine.org/20150521-ocean-viruses/
jonmc12··on The 10,000 Year Clock

jonmc12··on There are no B players
I read the book Topgrading a few years back, defined A-player relative to the position: "An ‘A’ player as defined by Topgraders is one who qualifies among the top 10% of talent for the compensation available for a position (any position)."

I think this concept has been understood for many years in industry. However, In startup land, its been ego-cized a bit through logic like "people are the most important assets of startups, therefor there are good people and bad people, only hire the good people". But this logic alone is open for misinterpretation because whether talking about "A-player" or "10xer", good is much for a function of ability of an organization to empower a person in a position.

On the other hand, there is a reality that certain individuals will be an "A-player" more consistently in more positions than other individuals.. so I believe there is some value to understanding how an individual's general behaviors would, or would not, make them an A-player in specific positions. At the same time, its likely very difficult to deduce this kind of statement meaningfully unless the same person has worked with someone in multiple positions.

jonmc12··on With Lyft Line, Passengers Can Split Fares for Shared Rides
I've been using Hitch the last month or so, and Sidecar has had the functionality for some time as well. Its cool to see Lyft and Uber offering the service.

IMO, a big win for consumers, because offering more service-level options, and driving down pricing. With Hitch, it usually costs me $9 for what costs $16-22 on UberX, Lyft or Sidecar. Thats a nice savings, even if it takes me 10min more to get home. I could really see mass adoption coming from the service who nails this and provides the option that is better than Muni, but cheaper than individual car service.

Another aspect of this service I wasn't ready for was that the social dynamic can completely change the ride-sharing experience. Its different when you are just chatting with a driver, vs a 3rd or 4th stranger jumping in the car. It will be interesting to see how others react and expectations evolve as it becomes mainstream.

jonmc12··on Justin.tv has shut down
Was re-reading "Why TV Lost" essay by PG (https://news.ycombinator.com/item?id=501696), which seemed inspired by Justin.tv. A lot of the points in the essay from 5 years ago were really telling, including the role of piracy in the user experience.

One interesting excerpt: "The somewhat more surprising force was one specific type of innovation: social applications... This was what made everyone want computers. Nerds got computers because they liked them. Then gamers got them to play games on. But it was connecting to other people that got everyone else: that's what made even grandmas and 14 year old girls want computers."

The app may be a subtle PR campaign playing off the satire. Can't go wrong with app puns either.

jonmc12··on People Don’t Actually Like Creativity
Cleese says to switch back and forth and specifically drills into the aspect of getting into open mode. I didn't take that to mean you should not switch back and forth within a state of single flow if you can.

Also, I think the characterization of "open" as "brainstorming" is a bit more limited than Cleese intended. I understood "open" to mean in consideration of observed feedback. One example he gave of this was "playing" with other people, and thats brainstorming, but thats just one case where the feedback is from other people.

I do think there is something incomplete in the talk, which is the notion of deliberate practice - I'm not sure the distinction between general experience and deliberate practice was as well understood a the time of this presentation. Yea, the more you practice, the faster you can work, and compress the "open"/"closed" cycle - in this sense mastery of work and play increases potential creativity.
