Comment Re:There's something to it (Score 1) 281

Well, we're at least half in agreement. Our brains are programmed to favor dietary items which are high in fat and high in saccarides, Which isn't surprising as we evolved to survive, and high caloric intake was valuable in survival. We've just gotten smart enough not to need such a large volume of input to produce the energy we need to survive. All the processed sugars and fat which are bad for us (well, most of them) exist in exactly the same form in paleolithic era foods - they're just not surrounded by indigestible fibers.

tl;dr If people would stop eating so fucking much and get out and exercise this probably wouldn't be an issue.

Comment Smart. Dumb. Doesn't matter. (Score 5, Interesting) 243

Success is about being in the right place at the right time with the correct skill set to take advantage of the situation. Hard work is the way you maximize your skill sets to that should you find yourself at the intersection of time and place you take advantage of it. The thing is, not only can't that intersection be anticipated, it can't be identified even when it's happening. Only in hindsight can you look back and realize where the critical moment was when your success actually started. Sadly, most people can't even do that. They believe that climbing the mountain of success was solely the result of having applied their skills and hard work, never realizing that - as the result of fortuitous time and place of their application - they were actually running down hill from that point on.

How do you propose to reimburse people who generate or curate content, such as the editors at Slashdot, or the writers at Cracked or the Onion?

With every content media you pay for the medium (paper, traditionally for magazines and newspapers) but that barely covers materials and distribution. The advertising pays for creating the content.

Comment Re:Use Roman Concrete -- no rebar necessary. (Score 1) 108

The article is likely wrong. There are no high tensile forces in the pantheon, including the dome, at least not what we would consider "high" today. The structure is a (mostly) compression-only building. The oculus is a compression ring and the dome shape is close enough to a parabaloid that any tension forces are negated and the thrust at the base minimized.

Concrete has tensile strength all by itself. If I gave you a rod of concrete just an inch thick you wouldn't be able to pull it apart. Even tension from bending is allowed in the design of modern structures with every-day concrete. There are several modern admixtures that even allow cracks to self-heal in the presence of moisture.

To see real math applied to the use of all-compression spanning structures, consider hyperbolic paraboloid (saddle shaped) or inverted catenary (paraboloid domes) roofs.In some cases (usu. flat-ish roofs) it's architectural and rebar or prestressing steel is required, but for pure utility you can define a curve that keeps the surface in compression and then the only steel that is added is typically for shrinkage and thermal cycling crack control (which is cheaper than using shrink-compensated concrete mixtures). They're rare because they tend to be very labor intensive to form and cover.

Comment Actually, it's worse (Score 2) 188

Worse that pay-to-play software of dubious quality is the entire lack of support for major applications, and a complete lack of serious productivity and mainstream apps. Many of the apps are poor stepchildren of their Android and iOS counterparts if they even exist at all. A useful, app-style browser is woefully missing (for those who have convertible tablet/laptops, you can't have Chrome, IE or FF act as an app/finger centric if you use them in desktop mode.)

The iOS and Android app stores are full of shit, too, but at least there's some good stuff out there. For MS, all they have is the shit.
