  1. Current faux-meat substitues on Slashdot Asks: Would You Eat Lab-Grown Meat? (dmarge.com) · · Score: 1

    People will eat it if it is cheaper and reasonable tasting.

    My issue is that I'm old-school and think that generally meat tastes better on the fatty side and cooked on the bone, but I'm probably in the minority. For those that prefer sterile low-fat off-the-bone preparations, it'll probably get good enough, soon enough.

    I suspect that early on it won't be that much different than the relationship of Crab and Surimi/Krab. Maybe it will get better over time.

    In China, the spread of Buddhism basically lead to all sorts of mock-meat products (mostly made of tofu, tempeh, fried-gluten) which people eat regularly even if not vegetarian, so as long as it's tasty, I suspect this lab-grown meat will have enough of a following until it gets entrenched and you can't even order the real thing for some dishes anymore except in a high-end restaurant.

    Think about it this way, most people that eat a fair amount of meat on a regular basis will generally unquestioningly eat a sausage or hot-dog when given an opportunity. I think that says it all.

    But if the purveyors of this lab-meat try to tackle it from the premium eco-angle, I suspect it will get crushed like synthetic diamonds (which even though are superior in every possible metric to conflict or deBeers diamonds, are perceived to be less desirable and thus unmarketable).

    Disclaimer: I voted for him both times.

    It isn't even a matter of manned vs. unmanned exploration. The Space Shuttle was the Universe's most cost-overridden project ( until the F35 came along). The original promise was that the materials scientists would produce a monohull insulating layer. The moment they gave up and announced it would take 70-zillion separate, custom "bricks" , the program should have been shut down. Heck, it would have been cheaper to shoot astronauts 3 at a time on Sat-Vs, shoot up some payloads & return vehicles (modded Apollo3s) etc. than what it cost to build and maintain the shuttle fleet.

    But think of the *jobs*, I mean think of the the *children* supported by those *jobs* (don't you remember the booming job market in the 70's)...

    Don't kid yourself, they didn't burn the money, the money was spent to create jobs, not a space shuttle. Unfortunately, the government isn't very efficient when spending money to create jobs (lots of it gets lost in pockets along the way), but that's something you can't fix with money. Well, maybe campaign money is arguably what makes it inefficient, so maybe you can fix the government with *less* money.

    I think retrospectively, Shuttle program and the Airbus A380 and A400 programs are probably the most comparable here... The F35 is an order of magnitude above these...

    Absolutely right. In Carter's position I would have made the same call, because I'm sure somebody at NASA would have convinced me that reusable must be inherently cheaper eventually, and that we need to go through these growing pains to debug the technology. But in hindsight it was the wrong call, and it set space exploration into a malaise from which is has not yet emerged.

    Well, SpaceX and BlueOrigin are crowing about "resuable" being the future of space flight, you might argue that in abstract, idea of the Space Shuttle program wasn't wrong, it was just the wrong architecture**, executed all over a huge geography to get funding instead of efficiently (kinda like Airbus Planes), and managed like a huge bureaucracy (like any other govt program).

    I would argue that even theoretically, you could have only fixed 1 out of the 3 issue, and the biggest problem is that it inevitably (because of the funding) became too big to fail which means once it gets to the wrong direction, it's too late making it nearly impossible to fix a wrong architecture.

    However, the "malaise" of space exploration isn't really a function of the shuttle. Perhaps it set manned exploration back a decade or so, but space isn't going anywhere. The "malaise" is really because there's no immediacy to the problem (e.g. beat the Russians). Remember, the "space" budget is really a jobs-and-kickbacks budget that happens to to spent of space *stuff*. It's 100% discretionary spending (like a household budget for Netflix or a vacation in Greece).

    Sometimes, you want to spend your discretionary money on Netflix, sometimes you want to take a trip to Greece with your money because your friends say it's the best vacation. Maybe your family debates that and makes a decision. However, sometimes you make the executive decision to spend that money to climb Kilimanjaro not because it is easy, but because none of your friends have gone there before and you want to be the first to take a selfie from space (oops, I mean Kilimanjaro, Virgin Galactic isn't operational yet) . To help sell that Kilimanjaro idea, you agree to make a stop-over in Miami for a couple days where your wife's family was from and you agree to buy the kids a new ipad for the trip. Congratulations, you get the trip, but long after the trip, when the selfies have scrolled off the bottom of your Facebook timeline, lament you've been missing out on House of Cards and regret sets in as you open your credit card bill.

    If you made the other decision, you would probably still regret it watching House of Cards, trying to forget your friends Instagram pictures from Greece and save up for a trip next year, but really, just get over it, like all discretionary spending, it's never totally satisfying to rehash regrets unless they materially affect your life.

    If things are more *immediate* (e.g, you thought your kid had 6months to live), maybe you'd choose to max out your credit cards to take that Greece vacation now (and do the Netflix too). Taking trips around the globe might be a more exhilarating way to live, but probably less sustainable.. China and India are probably spending far less than the US did for their space exploration programs because they effectively waited for the technology curve was more favorable. Space ain't going anywhere anytime soon and maybe we need a bit more "malaise" from our discretionary government spending programs.

    **the Shuttle architecture (like others) is only nominally "resuable": SRB is toasted, a recovered external fuel tank needs rework, as does the shuttle engines. Similarly, Falcon has second stage which is toasted, a recovered first stage which needs rework and the Dragon is theoretically about as reusable as the shuttle. Not too different abstractly, but arguably a better architecture.

    If you want some BigAssTechCompany to open an office in Fresno, probably the best way to do that is to join said BigAssTechCompany at the headquarters (perhaps in the bay area), work your way up the ladder and become a known leader in the company. Then you can make your case that it would make sense to open an office in Fresno and if the higher-ups agree, then move to Fresno and become a site leader.

    If it actually made sense (not saying Fresno makes sense), but nobody has done it yet, it is probably because the transplant-able person that could make it happen doesn't yet work for BigAssTechCompany, or maybe such a person doesn't actually want to move back to Fresno after working in at headquarters for a while (perhaps enjoys living bay area or has kids in school, etc, etc, or maybe has just grown to hate enduring the summer heat in Fresno)...

    The trick is that they're (probably) not actually violating the law in most of these cases. I'm under the impression that it's not the employer that normally hires the H1B replacement. Instead, they decide to "outsource" IT from their own employees to Wipro or Infosys or similar Indian company whose US subsidiaries are the ones bringing in all the H1B-visa employees.

    Obviously a violation of the spirit of the law, but unless someone has some relatively damning evidence leaked from inside one of the outsourcing firms, there's nothing to stick a letter-of-the-law violation to.

    IANAL, but just thinking maybe the reverse "trick" is to take the recent NLRB decision that concluded that by it's actions, McD's a *joint* employer of their franchisees' employees and apply it in this situation. If a company is now effectively a *joint* employer of the H1B replacement, the company is effectively hiring a cheaper H1B replacement for the worker they fired which might come under scrutiny.

    Now you could still outsource a function, but not a job. But now, there effectively would be no training of replacements, because the contracting company you hired would need to replace the operations completely (not just a job). Of course many functions might be amenable to this (e.g, payroll, hr, etc are commonly completely outsourced as a function), but at least this avoids the issue of needing to train a replacement for a outsourced job.

    That's probably because caries (aka cavities) are not caused by sugar or meat, but by acid. How much acid your teeth will experience (relative to the foods you consume) is mostly related to the composition (and volume) of your saliva, how close your teeth are spaced and your brushing and flossing habits and your night-time saliva situation (nose/mouth breather/snoring).

In this quite reasonable and understandable paper he and his cohorts attempted to argue that a wave function could not encode the full description of reality because of the consequences, there was something else required. By using math, they basically forced the hand of those that favored the Copenhagen interpretation of QM to accept what was then considered absurd.

    This makes the reality of P and Q depend upon the process of measurement carried out on the first system, which does, not disturb the second system in any way. No reasonable definition of reality could be expected to permit this.
