3D printing isn't magic replication of anything and everything of which you can copy the shape. There is far more to it than that. 3D printer materials have specific properties that make them suitable for some uses and useless for others. The fact that objects are printed in layers affects their performance in some applications as well.
If you copy the leaking washer you'll have a leaky faucet when you install it. If you have a good washer to copy then you may as well install it instead of making an inferior copy. The material the washer is made of and the material you print with have different properties. A 3D printed ABS or PLA washer would not work like one of the originals because of material differences and because 3D printed stuff is made in layers, unlike the original.
What I'd like to know is why are units named after people? It is just crazy. If you want to honor a physicist, erect a statue to him/her. Why name a unit after them and obfuscate the meaning of the unit? What is a Newton? What is an Ampere? What is a Volt? How can you use such a unit in dimensional analysis? Naming a unit after someone guarantees extra effort and adds a layer of obstruction for anyone to learn and understand more physics. It hides the physical meaning of the process/properties that underlie the unit. If I were a physicist and they asked me if I wanted some constant/complex unit named after me, I'd say hell no. Physics is tough enough without pointlessly naming units after people.
And what is up with the Ohm and the Siemen? One of those guys got a free pass...
I'm not sure I see the value in a 3D scanner. One of the great uses of a 3D printer is to make custom parts for other things I am building. If a part exists (the one you are scanning), why do I need to duplicate it with my 3D printer? If I need multiple copies I can just buy more of them. OK, so maybe the part to be copied is expensive and made of milled metal and does something useful that I think will be OK in plastic in my application- let's say a bearing block. None of the 3D scanners I have seen have high enough resolution to allow the function to be duplicated. So as far as I can tell, these things are good for roughly duplicating small, nonfunctional objects.
I can't imagine not using CAD to design custom parts to be printed on my printer. Will people really spend $500+ to copy chess pieces and salt shakers, and not learn to use CAD so they can create things themselves? Not likely. Once you have learned to use CAD software, a not too difficult thing to do, you won't have much use for a low resolution scanner. And then there's Thingiverse and sites like it. Even if you don't CAD yourself, there are others who do and post to Thingiverse and similar sites.
I can see some value in a scanner that allows large objects to be scanned and miniaturized (like people or their faces, or pets, etc.), but something that can only scan small objects that fit on a little turntable? Meh.
No, you don't understand. Amnesty and immigration are needed to keep the social security Ponzi-scheme going. There simply aren't enough young people paying into the system to support all those retired old people. We need to make the undocumented workers legal so they can be taxed.
What Ellison, Zuckerberg and other of their ilk want is more H1B visas. H1B visas are needed to keep salaries down by replacing relatively highly paid American tech workers with lower paid imports who will be unable to leave their awful working conditions to seek better elsewhere lest they be sent back to the countries they worked so hard to leave.

I was an EE for 22 years, worked for some of the biggest names in the business, and in my early 40s they tried to stick me into management or marketing. I stayed in engineering and as a result, hard a hard time keeping jobs and finding successive jobs. After a couple layoffs (stock price drops $2 per share, so the brilliant CEO, who wants to look proactive to shareholders, tosses a couple hundred people out on the street, including engineers in their 40s).
As an engineer I was many levels removed from the end users of the products I worked on. None of the stuff I ever worked on ever made a big impact in anyone's life. At work they were always pushing us to work more and more hours, even as benefits declined. Every time I was forced to change employers by either Dickensian working conditions or a lay-off, vacation time dropped back to next to nothing. Trying to take vacation time as anything other than occasional three day weekends resulted in management giving me the hairy eyeball. Trying to take advantage of the company-paid higher education "opportunities" got me the same push back as trying to take vacation time. All the time it was getting harder to find work, more and more H1B visas were getting the jobs.
I saw the writing on the wall and went back to school for 6 years. Now I'm a dentist. I work in public health dentistry, treating mainly working poor people. Every day I relieve people's pain, repair their smiles so they can work at jobs where they have to meet the public, educate them about how to take care of their own and their children's oral health, make dentures so they can smile and chew food again, etc. Everyday my patients thank me for the work I do, sometimes with tears of joy in their eyes. At work I am treated with respect. I work a 4 day week (scheduled 10 hours per day, but sometimes takes a little longer to finish paperwork) can take vacation without anyone complaining or pressuring me not to, I have time off and an allowance for continuing education (which I must use it to maintain my license, so there is zero resistance from management). I earn about what I used to earn toward the end of my engineering career. In summary, my work is far more rewarding than engineering ever was. If I could do it all over I would have been more selective about where I worked as an engineer and would have made the career change much sooner.
Finally, when I was deciding on my new career, I started with healthcare because they can't send your job to another country. I spent time with physicians and medical students and with dentists. I found the physicians and med students to be even more unhappy than I and my fellow engineers, and I found dentists to be a pretty happy bunch of people. Med school is brutal and after graduation the insurance companies really kick those guys in the nuts at every turn. That and the detailed work with the hands are what sold me on dentistry. Its very difficult to get into dental school (80+ applicants for every seat when and where I went to school), and the schooling isn't easy, but I don't think it is as demanding as medical school (I know because my wife was in med school at the time).
People are strange. Many are unable to set and target long term goals. Take brushing teeth, for example. Most (but not everyone) people know that you have to brush your teeth in order to keep them, yet many people don't do it for a lot of different reasons. I see patients every day who don't take care of their teeth and come to me only when something hurts, which is often too late to save a tooth/teeth. They often tell me about other things going on in their lives and I get the impression that they let a lot of things slide until those things demand attention one way or another. They live from one moment to the next, reacting to whatever stimulus demands the most attention. Others grow up in households with little or no parental supervision and have never had an authority figure in their lives tell them they must brush their teeth daily. None of these people - the ones who could benefit the most- are likely to buy a brush like this.
While this device seems like a great idea, I think its target market is actually very small. People who are technologically sophisticated enough to understand what this device does and to want one badly enough to spend the money on it are probably already brushing their teeth adequately.
I prefer the oscillating head type brushes because they reduce the manual dexterity required to get the brush tips moving in ways that get the teeth clean. With the oscillating head brush you put the head against the teeth and slowly move it across the arch. It doesn't take much manual dexterity to operate it. Sonic brushes clean OK, but you still have to move them around a lot more, similar to brushing with a manual brush. Many people, especially kids, lack the motor control to operate them properly.
A power brush that beeps at 20 or 30 second intervals is really all the feedback anyone should need, but then again, knowing that your teeth are going to rot if you don't brush should be sufficient stimulus to get people to brush and it doesn't, so who knows, maybe this will turn out to be a great device.
Finally, I question the value in turning everything into a game. What does it say about us that we have to have immediate rewards for every little thing we do in our lives? What about simply teaching people to think critically about their lives and what they want their distant future life to be like? Turning everything into a game keeps them focused on the moment.
start looking into the lives of lottery winners or big sports gambling winners.
I suppose if one could travel backwards through time there wouldn't be much need to cash in big when you could simply cash in small as often as you need money for anything. Still, there are some very expensive things one might want that would require large cash outlays.
That's the only reasonable thing to do in a situation like this and it the chances of it working are about the same as removing the wifi network. Praise Jesus!
I have an Asus laptop that was set up with Splashtop and Win 7. I figured that Splashtop was there so you could access you email and the web when Windows failed to boot properly, as it inevitably does. I thought it was a step in the right direction- recognizing that windows is unreliable- but it died because Splashtop had a poor UI.
If they had just done a clean linux install it would have been fine. The laptop even had a second power button so you could choose which OS to boot by pushing the appropriate button.
I've taken Windows off the machine and now it runs Ubuntu, much more reliably than it ran Windows. I may reinstall windows to run in a VM for those few programs I need that have no linux equivalents.
When neither parent can afford to quit his/her job, I would question why they are parents. I'm not suggesting retroactive abortion, but some consideration of your economic circumstances before deciding to make a baby seems prudent.
Teach your kids critical thinking skills instead of video games. Save them from the mistakes their parents made.
get pierced and tattooed. The freedom to deviate from "norms" is earned. Any idiot can go get pierced and tatted like a 19th century sailor, but keeping/finding a job while being pierced and tatted is a different story. Once you've established your brilliance you are sometimes granted more freedom. Here's the thing a lot of you will find hard to accept: not many of you are ever going to be so good at what you do that you'll be granted the freedom to look like a sideshow attraction, and that if you look like one before you've demonstrated your value, you may never be given the chance to do so. Get over it. As brilliant as you are, I am certain that you can come up with ways to express your in-duh-viduality without body modifications. I have great confidence in your abilities. Now get out there and express yourselves without turning your bodies into something that resembles every box-car that passes through south-central LA!

Post-Snowden, even the most clueless moron must know that social media are under constant surveillance and that all said there is being recorded.
Posting something to the internet IS recording, whether or not the NSA or anyone else is looking at it in real-time.

Um, I think this was Customs, not the TSA...
But what can you do? I know it's bad for the guy who plays the things, but I wouldn't want to shut down customs over it.
