How I gave up dreaming about the big city and learned to love the suburbs

We learnt a lot since 9/11 about how radicalization works. It's not happening mainly through personal trauma, but through indoctrination, usually through schools and universities.

Construction costs generally rise with the height of the building, both due to higher structural demands and because of additional functional (usually also legal) demands - like two elevators and two fire escape stairways for buildings higher than 8-10 stories. Maintenance is also more expensive for higher buildings. Higher buildings also demand larger distances between them to allow light and ventilation. Because of that - except for places with unusually high density like Hong Kong and parts of Manhattan - the sweet spot for high density, construction costs and quality of life might lie in the 5-7 stories range (typical for Paris and Barcelona). Regarding Hong Kong housing situation - in spite of the high level of economic freedom in other areas, the housing market is in a large part state controlled, with waiting lists for buying an apartment.

Taking Cold Showers 15 years ago

Cold showers just make me feel great. Never suffered of those.

I also use them after workouts, as described here: http://paleohacks.com/questions/995/what-is-the-deal-with-co...

"Invented by the French and used by virtually every elite athlete on the planet, it is often confused with some kind of torture. Right after working out, hop into the shower. First, cook yourself for no longer than 5 minutes in hot water, relax, get those blood vessels well dilated. Then slowly add cold water to the mix until it's so cold you can't stand it. Endure it. Focus the water on the back of your head and the muscles you just worked. Feel the blood vessels constrict. Stay under it for as long as it takes to really cool off - 2 to 3 minutes. The time it takes to cool down will increase as you adapt, and the temperature for cooling will decrease. Then, switch the hot water back on. The blood vessels will dilate, and inrushing blood will flush the lactic acid out. Start the cooking process again. Repeat at least two cycles and finish on cold. This induces a tonic effect and you'll rebound, flushing again as your body warms up in your clothes."

I'd be interested to see a map that shows the countries by their current trends to or from democracy (would better replace that with "personal liberty") rather than the current state.

I don't think that while in war you weigth the enemies' lives (especially the combatants' ones) the same way you weigth those of your own. At least not until you approach anywhere close to a massacre of enemy combatants.

It actually makes sense. To predict the economy without government you need to predict trends and the behavior of many people. To predict the government moves you need to predict the whims and arbitrary actions of individuals, and do that according to their perceived political gains.

In spite of the (justified) complains you get about the false positives, I think that's a great way to go. Unlike with email where missing a message might be critical, in search I'd rather have even as much as 10-20% false positives than deal with the spam sites Google delivers.

More in general, concerning the front page search examples: "cure for headaches" works very well indeed compared to google. However, "global warming /liberal" is a bit irritating. I understand the rationale behind it, however there is this slight difference between finding only what one is looking for and hearing only what one wants to hear. To find anything non-mainstream might necessitate a technique like this in Google where you otherwise don't see anything else in the first 50 results... But maybe you can strive to find for me what's really going on and not merely what's mainstream and politically correct. Thinking about it, your blocking of domains like Answer.com might be a great step in that direction anyway.

I think it has the potential to revolutionize drawing and resemble the traditional drawing table. Can be very comfortable and efficient for anyone designing physical objects (civil engineers, architects, industrial designers). There are already graphic tablets, of course, but they are very expensive and very specialized. This makes me hope that my current way of working staring directly at the screen while moving the mouse might change in a few years.

Agreed, but I could imagine one implication that might be revolutionary for urban areas. With driverless cars, it might easily become much more economical not to own a car at all. Even when one does own a car, they don't have to park it within short walking distance form their destination, as the car parks itself. Free from strict parking requirements and regualtions cities can become much more friendly to pedestrians, and buildings (especially medium-high ones) may become cheaper and more free in their design.

Safety is probably the original reason for having building codes, however today the very significant majority of these rules (measured by both quantity and design time required for their impementation) has nothing to do with safety. Codes dictate building masses and building areas, building lines, requirements for parking, facade design, choise of materials, form of the roof, floor heights etc. etc. Some of those don't cause very much damage since they are useful and most architects would implement them anyways. As to the others...

I've seen this nonsense for a few years now in all kinds Architectural publications. One such example: http://www.mvrdv.nl/#/projects/research/181pigcity. Unfortunately, many architects and architecture students would buy any green (or otherwise hyped) BS thrown at them without questioning it.

I think the most prohibitive aspect of the "vertical farming" is the enormous cost (in materials, labor and energy) of building highrises or even buildings of more moderate heights, compared to the cost of growing any legal kind of crop on farmland and shipping it. Structure will have to be significantlly more massive to carry the loads of some soil and water. And not a word about competing land uses in Manhattan... But let's assume we can afford to ship the crop 10 or 30 miles into the city from a place with cheaper land, rather than a 1000 from far far away.

Otherwise, I actually believe the problem of lighting is solvable - for crops that require perhaps 3-10 times as little light as available in an open field on a certain location. Light can penetrate from the sides of the building. A structure shallow ebough compared to the floor height might suffice, say 10-15 meters for a floor 3 meters high. Close to the equator sunlight is abundant so even having less light by an order of magnitude is probably enough for some crops. Further away from the equator it's trickier: the sun is much lower in the south and so more direct sunlight is gained so perhaps only two thirds of it are lost compared to an open field. But then, the structure casts very long shadows which may prevent the land "behind" it from being used for farming (vertical or otherwise).
