Valid points. But generally, the cost of entrenching is a bet against innovation. Maybe you're right and it's a good bet to bury several billion dollars of copper. I wasn't thinking the innovation would eliminate cable, the analogy to DSL in the home walls was that I'd paid to entrench what turned out to be the wrong kind of cable.

Submission + - Engineering Groupthink: How Polarized Opinion Works (hbr.org)

retroworks writes: Harvard Business Review (5 free articles until payall warning) has an interesting article about groupthink. The authors describe a study of two focus groups. One is from classically "red state" conservative Colorado Springs, Colorado, USA. A second focus group hailed from more liberal leaning Boulder, Colorado. Individually, members of each focus group were surveyed for their opinions before the groups met. Individual members (as anticipated) trended conservatively in Colorado Springs, and liberally in Boulder. Everyone was re-surveyed (anonymously and otherwise) after the groups met. After meeting with their opinionated peers, respondents opinions hardened. Conservatives answered the same surveys responded MORE conservatively, and liberals MORE liberally. When focus groups are randomized (blues and reds in proportion, in the same group), opinions become less polarized. The article discusses the effects on public policy and business decision making when groups assigned a problem to solve self-select and recruit people like themselves. Diversity leads to more intelligent decision making. Or if you are selling a specific (weaker) solution, be obnoxious to reduce participation from competitive views. Incentive-driven opinion benefits from the lack of diversity, protecting its agenda by driving away newbies who avoid trolls.

Maybe this is nothing new... the effect of co-ed dorms vs. single-sex dorms and fraternities has been studied for decades. As someone who has participated in /. for about 15 years, attracted to intelligent discourse, I notice how many mod points must today be spent on flamebait. There is still good debate, but frequently someone making an otherwise very valid counter-argument dilutes its effect with emphatic hostility and ad hominem attacks on the original poster. Is the ratio of "inciteful" to "insightful" going down? It's no way to attract women slashdotters, btw.

As an American married to a European, I've often been asked by puzzled Europeans as to why Americans build houses from wood. Alexis de Tocqueville probably said it best (Democracy in America Vol II, Chapter VIII):

"I accost an American sailor, and I inquire why the ships of his country are built so as to last but for a short time; he answers without hesitation that the art of navigation is every day making such rapid progress, that the finest vessel would become almost useless if it lasted beyond a certain number of years. In these words, which fell accidentally and on a particular subject from a man of rude attainments, I recognize the general and systematic idea upon which a great people directs all its concerns."

Americans regularly get second mortgages and put additions and improvements to their homes, expanding and adapting them. The less this is true (inner cities) the less likely the home is made of wood. And that may turn out to be true of many high-line wires. I'm not sure about power lines, but would assume we'd pay for telephone cables to be buried at the same time, and that seems incredibly wasteful. If the USA paid to put all the telephone cables underground, how will it pay off if everyone goes wireless, as has happened in most rapidly emerging market cities? When I had my home rewired in 1998, I thought it would be wise to pay for double phone lines, put in for DSL cable. I wish I could get that money back and put it into a savings bond.

Comment What Works and What Doesn't (Score 2) 92

What works is the "tinkerer's blessing" (opposite of the curse of natural resources). Chronicled in Yuzo Takahashi's history of Japanese radio technicians https://muse.jhu.edu/login?aut... , development is best done through normal trade with geeks and technicians. South Korea, Singapore, Guangdong, Taiwan, etc. all developed from refurbishing and reverse engineering used technology. Benjamin Franklin was engaged in buying used surplus printing machines and textile machines for reassembly in the USA, Technicians, nerds, repairers, fixers tend to be smart quiet truthful people, and when economies grow from talented knock off (Shanzai in Chinese) to outsourced contracting to ODM, you wind up with Terry Gou, Simon Lin, and Lee Byung-chul.

What has tragically happened in Africa and India is that do gooders and celebrities like Annie Leonard have found a recipe of white guilt and created a bogus "e-waste" crisis which puts African geeks and nerds in prison. FreeHurricaneBenson. Forums like Slashdot, where repair and tinkerers gather, have been important places to assess the ewaste hoax. http://retroworks.blogspot.com... I lived in Africa in the mid 1980s and have been finding win-win trade with display devices for almost two decades, and see Africans getting increasingly furious at the people making up fake stats, taking pictures of kids at dumps, and making money without sharing.

Submission + - Space E-Waste? Or Russian Killer Satellite? (ft.com)

retroworks writes: Financial Times reports:

"For the past few weeks, amateur astronomers and satellite-trackers in Russia and the west have followed the unusual manoeuvres of Object 2014-28E, watching it guide itself towards other Russian space objects... The object had originally been classed as space debris, propelled into orbit as part of a Russian rocket launch in May to add three Rodnik communications satellites to an existing military constellation. The US military is now tracking it under the Norad designation 39765."

"Its purpose is unknown, and could be civilian: a project to hoover up space junk, for example. Or a vehicle to repair or refuel existing satellites. But interest has been piqued because Russia did not declare its launch – and by the object’s peculiar, and very active, precision movements across the skies. Russia officially mothballed its anti-satellite weaponry programme – Istrebitel Sputnikov or satellite killer – after the fall of the iron curtain, though its expertise has not entirely disappeared. Indeed, military officials have publicly stated in the past that they would restart research in the event of a deterioration in relations with the US over anti-missile defence treaties. In 2010, Oleg Ostapenko, commander of Russia’s space forces, and now head of its space agency, said Russia was again developing “inspection” and “strike” satellites."

It's an international group which helps defend falsely accused "geeks of color". Here are two recent examples of FTR projects.

1. Ambassador program flies students and techs overseas to meet and qualify buyers of used tech who people are afraid to sell to based on "ewaste" myths. http://resource-recycling.com/...

2. Defense and petitions of UK TV repairman and ex-pat Nigerian Joe Benson, imprisoned in UK for "e-waste crime" based on "common knowledge" that 80% of exports of used equipment to Africa are burned in primitive dumps.

Comment What is the Next High Bandwidth Tech? (Score 2) 223

Breaking up the cable companies probably wouldn't do much without a new technology introduction. Break up of AT&T worked in retrospect because of advances in cell phone transmission, a leapfrog technology. Otherwise the Baby Bells would have still owned the local cable (like Fairpoint in New England).

I despise so much about Comcast. They have tech support / sales entertwined... Phone support techs in faraway lands read scripted lines like "your modem is at end-of-life". The "tech's" only knowledge of my modem is that it isn't rented from Comcast, can't tell me anything else? C'mon Tech Supporter! ...If you know it's "end of life" you must know when I bought it and must know what it is, right..? Ohhh... All you know is there's no monthly rent charge? Unfortunately, for now it's the fastest and cheapest bandwidth I can get. No other company is going to run a cable to my house. I doubt making "Baby Comcast/TWC" changes that. There has to be a technical advance, probably via satellite service. When Direct TV can compete technologically, cable will play nice.

Well, Yes, I understand, but that methodology (comparing identical twins to fraternal twins) was already used in 1992 to study alcoholism, and among the reasons it was not definitive is that taste buds are genetically inherited (for example), and dopamine receptors are genetically inherited. They could not say that alcoholism was genetic because correlations /= causation, and it was possible that diet and other causes, e.g. habits affected by taste, were being measured. http://pubs.niaaa.nih.gov/publ...

... It seemed to me that if the 1992 study could not determine whether alcoholism was genetic, or environmental, that the original poster had made a valid observation. If alcohol consumption could be caused by diet preference (e.g. people who love the taste of beer start drinking earlier in life, when the brain is developing, leading to stronger habits / dependencies), gut flora could also be affected by diet preference, habit, or tastes. I guess you could argue that is a genetic trait, but not nearly in as assertive a way as the Summary suggests.
