I hope it avoids making something almost, but not quite, entirely unlike coffee.

I find your lack of faith disturbing.

I'd suggest just getting a Raspberry Pi with Scratch. The bonus is there is some minor assembly required (the case) and all the wizbangery hardware is visible. And if the little tyke smashes it against the wall in a fit of rage against your efforts to force him to be a programmer, you're only out $50 (not counting the cost of the therapy sessions).

Doesn't sound very hospitable. Was this found on planet Zyklon B or something?

Not if the prosecution has a slam-dunk case. And I don't think a prosecutor would want to be caught soft pedaling a case like this - they are going to prosecute this with utmost vigor.

Labor is about 35% of the operating expense of an airline. Fuel is a distant second. Pilots are the some of the pricier elements of that labor pool, and are often unionized and do strike on occasion. Bean counters just love the idea of taking them off the spreadsheet through the magic of modern technology.

The airlines would love to see these aircraft running on a subway model - no attendants or pilots, maybe one person on the ground monitoring that the airplane stays on track. Just put a soda machine on each plane, one that takes credit card and charges $10 for an RC Cola (Coca Cola is $15 for 1st class only). Send a cleaner through once a day. No carpeting or upholstery, need to be able to hose it out quickly. Complaints? No one on the plane to listen to them except the other equally disgruntled fellow passengers.

Wait a minute...Louisiana? The state that has drive-through daiquiri bars ?

Driving with a Big-Gulp sized Hurricane in your lap (no straw of course, *wink* *wink*), that's OK, but powdered alcohol is irresponsible?

Another symptom of the college bubble - paying more and more for less and less. Even with TAs there is such a flood of students that the grading is overloading the system. Students now can't even get a unambiguous assessment of their capability in a subject.

OK, so now when an employer wants to see grades and transcripts, what should they make of those grades? Was that person riding the coat tails of a smarter partner? Yeah, I'm sure partners would change class to class, but some students are pretty savvy and will know to sit next to the smart kid in class for this reason.

I wonder how many copies of The Anarchist's Cookbook sold this week!

It is not hard to make dangerous things that go boom. Heck, some of the things that I blew up behind my garage when I was 13 would probably send me to Gitmo now. Believe it or not, that doesn't make me a terrorist.

Maybe it would be smarter to examine why people might want to make bombs and kill people, and work to make a world where people don't want to make bombs and kill people, even if the The Anarchist's Cookbook was on every coffee table in the world.

The War in Terror, just like the War on Drugs, will not be won simply by "just saying No". Until human motivations are examined, it will all be a horrendous waste of life, effort, and resources for no gain.

Why not send an unmanned habitat lander? Something that lands, deploys a habitat, then monitors the performance of that habitat and the health of the return vehicle *before* committing a crew? Knowing that they have a safe and established home base on Mars and a ride ready to take them back home would add some redundancy and encouragement to the crew. If a meteorite crashes into the habitat or an Exogorth eats it, the crew aborts the landing and returns home.

Only 11 more step's to recovery! Arrrggh, I'm back down to step 12 again!

Gosh, I'm sorry. Are any of your neighbors good for anything, or are they all hipsters too?

I guess Instagram and the aviator sunglass industry needs some love too.

The *only* folks who will go for this will be hipsters who would rather talk to an Amazon app on their iPhones than directly with a grubby blue collar contractor.

I have a neighbor who is a licensed construction foreman. When I need work done on my old house, I basically can assist with demo, site prep, and cleanup and he gives me a big break on the bill. He goes home with a case of my homebrew beer when it is all done.

That Amazon can even propose this business model really describes the sad state of affairs of the middle class, community, and humanity's ability to interact face-to-face. We need to put the fucking phones down and talk to each other.

Umm, rocket science is...rocket science?

Combustion CFD is a very difficult area. The problem is that there are so many interlinked phenomena all requiring special modeling methods that one really isn't quite certain of the accuracy of the result unless they can compare it to a physical model test, which is what is frequently done. Simply getting the correct boundary conditions can be very challenging. Failing to apply appropriate modeling and boundary situations leads to a garbage in/garbage out situation, but the numerical solution may look plausibly correct.

CFD is not use exclusively in design work except for very basic cases where the modeling accuracy is well understood. However, CFD for more complicated situations is still useful as it may illustrate behaviors and trends in performance in situations where physical observations are difficult (like in a rocket nozzle). The CFD results can be used to guide and interpret the results of physical testing.

Understanding CFD really requires PhDs who understand fluid dynamics as well as the limitations of the numerical models used. This is true in many industries, not just rocket surgery.

Ahem; that's "Matter of Color", thank you very much.
