Plus the "small" issue that until recently the EU didn't regulate NOX, so eurodiesels didn't comply with USA limits.

And for the years before we regulated NOx? All through the 70s, 80s, and 90s?

USA diesel in most areas is still filthy despite reduced levels in the last 5 years.

Where do you live that this is the case? Pumps have had ULSD since Jan 1, 2007. There were maybe a few exception areas but I think those were all phased out by 2010. They're now moving to ULSD for off highway diesels as well.

"Grand" money? What's that?

Typo, Grant money.

What nonsense. 15 years ago was the year 2000. Has human genetics changed? Have computers changed so much?

What does anything have to do with genetics? And computers have changed. You don't need a multi-thousand dollar AutoCAD or CATIA license to do modeling.

Why do you post such utter nonsense?

Why do you post as AC?

It has a use for some small, niche scenarios, but it doesn't do anything for most of us here, and I really wish we would stop seeing stories on it every other week.

With a 3D printer you could run a ~19th century machine shop from your own home. You don't use the 3D printed model. You use it to check fit up and then to turn it into molds.

You can melt iron with used motor oil even charcoal. Sand casting is still used almost everywhere for cast iron.

Give me a 3D printer big enough and I'll build you a tractor. Engine and all.

Who cares? I want my plastic to melt at 105C. I want it to melt at just above room temperature.

I can make molds. Anything I can think up to print I can turn into a mold for metal. With a furnace and some wax I can cast iron.

9L+ diesel engines are still cast. If your bed as large enough you could 3D print yourself a small 2 stroke engine, check for fitup and then build yourself an entire engine from scratch.

"Die Cast" used to be a marker of quality. With a 3D printer at home you can make anything the average machine shop could have made during the industrial revolution.

And because you can do it in 3D with cheap plastic first you can reduce costs. You think a bad 3D print job is expensive? Imagine screwing up a mold design for a 12L engine.

They're for your kids. I'm shocked at the number of Slashdotters that are talking about 3D printers like this.

Our local library bought one through Grand money and there are kids in there every week trying to learn to use it. MakerBot and Thing Verse work really well together.

It's how I learned how to Program. First I copied someone's program. Then I modified someone's program. Then I wrote my own programs. Kids are printing things out. Some get bored with it, some spend a lot of time with it. Guys are making desk top figures or monster trucks. Girls are 3D printing jewelery. The librarian has asked me to help out with teaching them some 'theory' behind stuff and I just gave them my parametric modeling book from freshmen year in college.

There are 10 year olds out there that can model better than your average college senior could 15 years ago. FIRST robotics is going to get a lot more interesting when you have people that can actually model. People that may be contracting your CNC shop to make a part. Kids that have grown up doing parametric modeling and actually know how to design for machining. (Because if they screwed it up on a cheap piece of ABS plastic and not your CNC machine.) There are going to be girls that will be asking their parents for a Revo 540CX CNC machine so they can make their own rings.

NPR also had a few interviews with the author of So You've Been Publicly Shamed .

Most of the examples were people that made tongue in cheek jokes to a small audience (their friends) and someone got 'outraged' at it and then they had the entire internet doxxing them and trying to ruin their lives.

It's 2015 and Americans are still dealing with the backlash over the terrible diesels that GM released in the 70s.

I laugh to myself every time someone tries to tell me how 'awesome' their 30 MPG is. I've been driving at 45-50MPG since I bought my first car 20 years ago.

Sadly we don't even get the best diesels Europe has to offer because there just isn't a big enough market.

She's unfortunately part of the current 12 year old generation of thinking that she knows about technology because she can use it.

What ever she does I guarantee there's something that's boring and repetitive that she hates to do. Upload photos to Facebook on 'throw back thursday'? Write a python script to parse all of your images randomly select 5 and upload them. She can maintain the same things that she's doing now but will have more free time and at the end of the day.

Name something your daughter is interested in or does and I can probably think of something to do.

Are you sure that they need to go to college? College isn't for everyone. The trades need intelligent people too. You can get paid for your apprenticeship/internship and work all day with your hands. The 21st century trades are the 20th century college degrees. Stuff gets easier & simpler to use/understand until it just requires someone smart/clever with training and not someone with a full degree. IT and Plumbing have a lot in common. You don't need to know fluid dynamics to know how to do plumbing.

You're already starting to see a shift in the medical community. Your average physicians assistant and nurse can do more than a medical doctor from 100 years ago. With the cost of health care rising they're going to start shifting work down to people with less skills. My wife has 4 years of residency, 4 years of medical school, 4 years of college and I would still trust a 'apprentice' trained nurse to put in an IV. My wife hasn't done the procedure in years. It's a waste of her medical knowledge and resources to have her put in IVs. In 20 years (if not sooner) there's going to be a robot that can scan you arm (they have that already), see where to poke and do it all before you know what happened.

IMHO IT is going to become a trade in the next 20 years. Like other trades they need to unionize and stop letting companies treat them how they are. After it's a trade then it's unskilled labor then automated.

"Teaching" as we know it is going to be replaced. We will always have teachers and people that foster learning but it will not be done as it is done now. K-12 virtual schools have taken off in Michigan. They have all online and 'hybrid' programs as well.

As a high performing student I would have watched Kahn Academy until I couldn't keep my eye lids up. The times I did have a question it could have been answered clearly and easily by someone in a video.

You're going to have super star teachers on youtube or other learning channel answering high level questions. (Like how Stack Exchange works). For those people that need hands on learning (which is a small subset of everyone) they will get hands on learning in person.

Why does a tiny small school in the middle of nowhere need both a French AND Spanish teacher when you could have someone in Spain and France teaching them through Youtube and interacting through Skype. Look at how Duolingo[0] has taken off. That's something that can be introduced to a 3 year old and they will intuitively pick up without fighting 13 years of trying to 'unlearn' some things in English.

Teaching as we know it is going to be automated away by technology. Code Academy taught me python syntax in an afternoon. It's clear and straight forward enough that I'm trying to get my wife to learn coding.

I would have spent every waking hour doing Code Academy in one window with Kahn Academy in the other if I had those tools available to me in high school. Instead I got stuck in some math classes with people that didn't care or distracted the teacher from actually teaching. In that scenario I would have benefited from where technology is taking teaching. So will a lot of other students.

Teachers are already experimenting with Fliped classrooms where students watch the lecture as 'homework' and the homework is done in class when the teacher is available. There's no reason the 'interacting with a teacher' part can't be done online. [Some rural schools are rolling out alternatives to 'snow days' where the students still learn at home](http://www.npr.org/sections/alltechconsidered/2015/02/02/382701005/for-some-schools-learning-doesnt-stop-on-snow-days)

There was a story that I can't find now about a teacher that had students write the book for the next semester. Take a classroom of 8th graders and have them make a LaTeX/Wiki page for each chapter they learn about. Make it the final class project and have different groups take a different chapter. The next semester improve on it. After a year or two you'll have a very well written and vetted wikibook on a class.

Why do teacher spend so much of their time on lesson plans? That's something that should have a good central Git repository. If you have a different style of teaching fork the project and make your own. Let teachers merge revisions back. You should have a good set of lesson plans, books, etc all. End the big book cartel and just start publishing LaTeX books for K-12.

I sit at home 400 miles away from my boss. I use my webcam for meetings. I push and pull git repos over VPN. There's no reason learning can't be facilitated in the same way. The best part about it is I can work it into my schedule. Some days I'm up at 4 am coding and feeding the kid. When the kid goes down for a nap, so do I. Then I'll work until midnight with dinner, TV and time with the wife intermixed. Apple has "At Home Advisors" so that people can get tech support from an American working at home. My company has moved almost all IT support to people working from home. Parents don't have to choose between raising a family and working.

With online courses my kids will learn the same way I work. If we want to go on vacation for a month in Germany all we need is internet access and both him and I can get our work/school work done and then eat dinner at a delicatessen, talk German with some locals and do some sight seeing. The learning and work still gets done but it didn't require a teacher in a classroom or even a building.
