Comment Stronger? Don't need it. Give me stiffer! (Score 3, Interesting) 106

Except in specialized cases for manfacturing and mining, we have all the strength we need in buildings and bridges. What we really want is something with a higher stiffness.

Find me a material which costs the same as A992 steel and has a modulus of elasticity of 300x10^6 psi (10x that of steel) and I'll make you a millionaire. With very few exceptions, MOE scales linearly with mass, from Magnesium to Iridium. Beryllium-Aluminum is an exception, but is very brittle and hella expensive.

Yeah, get me 500ksi steel at $0.60/lb would be nice, but if it still has E=30E3ksi it won't save me much in a building. Give me 50ksi steel with E=300E3ksi and I'll save you at least 20% on the steel tonnage in a structure.

Comment 0.05 from a single drink in 180lb person? (Score 4, Informative) 328

What chart are they getting their information from - the pre-teen's guide to Vodka?

0.05 is the *peak* BAC in a woman weighing less than 100lbs. At 190lbs, man or woman, you're only half way there (0.02-0.025).

And 0.20 - holy shit, you're well into the "wasted" range and probably are going to have troubles getting the key into the ignition by yourself. For that 180-190lb person, that's shotgunning a .375 flask of Vodka on an empty stomach. Maybe by "four drinks" the poster meant "Four doubles, as made by Bill Cosby at a fraternity hazing initiation"

Comment Re:Citations? (Score 2) 307

The industrial revolution allowed us to make things less expensively. What took 100 man-hours could be produced in 10, or 1. With it came the rise of unions and a power struggle between the robber barons and the working classes. The standard of living of most people in the industrialized world skyrocketed, with a good deal of the wealth trickling into the new "middle class". Industrialization made things, but required manpower to run them.

The rise of technology has made manpower obsolete. We're not making things with software but rather learning how to eliminate service people (technology in general, this is really all one wave and Y-C thinking software is somehow divorced from the IT revoultion that's been in progress for 40 years is bullshit). The end game isn't really "more stuff" but "automated services". We don't need more people to ramp up production - once the software is running it merely needs maintenance and a very small incremental staff to serve 100, 1000, 10000x it's original purpose.

That's where people are getting crunched. Now that the industrial revolution has spread to more of the world, there's international competition for those "factory" jobs, and so the Man can simple take operations to a cheaper location. But there's nowhere for the factory workers to go because all the service jobs are drying up too, thanks for software. The wages on the inside are good, but the inside is getting smaller and smaller as tech takes over more positions. That leaves a large, unemployable population.

There are some over 5000 years old and still work perfectly. Reproduction doesn't even require electricity. They are very low maintenance, but not very space efficient.

See what I did there? You've suggested a medium which may be somewhat practical for a very limited purpose, but wholly unworkable for the type or quantity of storage needed today. Unless you were going for humor, in which case I proffer a wry smile.

In reality, what is needed is not a static storage format but a dynamic one which regularly reads, verifies, updates, re-stores, and then re-verifies the files on a regular basis.

Comment Re:There's a reason: patents and standards (Score 1) 248

If someone patents in interface, it's gone from every other vendor. And since it's the "best" it's worth more, so a $5 item is now a $100 item (gotta pay back that engineering time). It's not expensive because it's mechanically robust or physically challenging to build the parts, it's because of the monopolistic lock in that each standard brings.

Plus, there are no (useful, universal) standards for home automation. Partly because it's just too wide open, partly because shit is changing all the time. How often has the primary power distribution in a home changed in your lifetime (0)? How many times has TV transmission (once, maybe twice)? How many times has network requirements changed (I've run out of fingers)? A simple, end-user programmable, extensible system available on a commodity basis from multiple vendors simply doesn't exist.

FWIW, 20 years is a blink of an eye for a house. I regularly run across basically the same dumb electrical components in 1950s buildings that are being installed in today's brand new homes. And multiple manufacturers offer interchangeable parts for houses built today and 60+ years ago. Until Smart stops meaning outrageously overpriced for the hardware provided, it's never going to be mainstream.

Which is why, if you're going to spend $10 on lottery tickets in a year, you may as well play when the payout is the highest.

I do agree that looking at the odds and the payout for anything where you can't get enough play to take advantage of the house odds is a fools game when it comes to making money on a regular basis. (And lotteries, with only 50% proceeds to the winners, is never in the players favor even if enough plays were possible to make the odds relevant)

Comment Re:Cheap entertainment for obsessive planners! (Score 1) 480

The sibling post nailed it. It's not an investment and shouldn't be considered such. Here's why: at the beginning of the two years, if you put the money into the bank your chances of becoming independently wealthy are exactly zero. In fact, the chances of having enough money for a weekend getaway in something nicer than a Motel 8 in your home town are still zero. Compare that to the chance of your retiring in those two years on lottery winnings. Maybe 1 in 10,000 - about the same as you next long distance call you receive having the same last four digits. That's not much, but it's still undeniably higher than retiring on what's in that bank account.

You may as well put the same amount of money into a music streaming service and decide, at the end of two years, which version had produced the most money - because after two years the entertainment will be just a thing of the past.

Comment Insurance is a tax on people who are bad at math (Score 1) 480

Insurance is a losing bet. It's a $1 ticket with an 80-90% payback. The funniest part is that it's a bet you *do* hope to lose. Rather it's a business decision, a hedge, which does not always need to show a positive ROI.

In the case of a lottery ticket, it's not a business decision. It's a lark, an entertainment. It's also one of the only ways to become independently wealthy with almost zero work (12 minutes at minimum wage, less than 5 minutes of labor at average wage). For 99% of the people out there, it's the *only* chance they will have of becoming independently wealthy. And someone *will* win eventually.

While I can't argue that people are, as a whole, bad at math. In fact, they're even worse at probability than general math. But it's not necessarily a tax on people who are bad at math, it's a peek at a life they would never, ever encounter for themselves in the normal course of their lives.

FAA can do anything they fucking want; nobody else in the world will give a shit. Do you really think if the Russian, Indian, or Chinese equivalent of the FAA pulled this that the US would take it in stride? Of course not. We'd claim they still don't have any right to reserve property on the moon.

And it would come down to who had the guns and is willing to use them. Which, to be honest, is all property rights really is anyway.
