That's where experience in having built a printer comes in handy. In an FDM printer the head is massive. Using multiple heads in parallel doesn't relieve you of the burden of accelerating them or the limitations of the materials you are melting. You won't get a 10X improvement in FDM by using multiple heads.
A laser that fuses powers or a print head that squirts tiny droplets of glue might allow speed increases, but might also compromise the strength of the parts and limit their use to decorative stuff. Those options and STL printers that use light to solidify a photopolymer resin are messy to use and require the prints to be cleaned up after removal from the printer. None are good options for use in the home due to the mess.
I am skeptical. If you're using FDM, I think that in order to print 10X faster, you can't use either ABS or PLA. The print head of the machine will have to be very low mass, which also rules out plastics with high melt temperatures like ABS and PLA. I don't think FDM printing can achieve a 10X speed increase.
If you go to stereolithography where you're using a projector to harden a photopolymer, you might achieve a 10X speed increase with the right chemistry and the right light source.
Without any evidence of what the kid is doing or even knowing if he has built an operational prototype, meh. All sorts of people claim all sorts of stuff on the internet without backing any of it up.
You can vote republican even if you believe in anthropogenic global warming, and they'll be happy to have your vote. You just can't have anything to do with setting the group's policies/platform/agenda. No one in the Republican party's leadership can say they believe in anthropogenic global warming and remain in their leadership position.
" for instance, by making clear that you can believe in human-induced climate change and still be a conservative Republican."
But you can't. The Republicans won't have you.
Ignorance is a choice, just like belief. The real problem is to get people to reject ignorance. The difficulty in that is that ignorance, like belief, is easy. Rejecting ignorance requires effort. That is why there are so many people who choose ignorance and belief over reason and fact.
For many, being identified as a member of a specific group, even if that group wants you to believe stupid things, is more important than objective reality. They must get something from that group membership that outweighs what they would get from reality. Reality CAN be a bitch.
Most of the human race will have become cyborgs? I think he's forgetting about the billions of people is underdeveloped countries and those who are continuously fighting and running from wars that have been raging for decades if not centuries. Maybe he figures all those folks will have killed each other off or starved to death by then.
2) Never feel and "loyalty" to a company or boss- they won't hesitate to kick you to the curb if some accountant decides you're over paid or not needed. They have absolutely zero loyalty toward you, you should have none for them.
3) Don't worry about bouncing from one place to another. If someone asks you why they should hire someone who bounces from job to job ask them how long they realistically expect to keep you around, and point out that they laid off XX engineers X months/weeks ago. Then ask them why you should consider taking a position with such an unstable employer. If your history of bouncing is a problem you don't want to work for these people anyway.
4) Don't settle for work that pays the bills but isn't interesting. The job will quickly start to suck. See rule 1.
attempting to make quality products (too hard, expensive) that can be driven to making financial assets that can be sold (easy, cheap). They are now finance companies that happen to make cars. Anything that doesn't enhance their ability to sell packages of auto loans to investors is of little interest. What Google proposes adds cost to the cars without enhancing the ability to sell loans.
The writer doesn't understand the strategy. The Beats name is the lure and the added sensors that justify the proprietary connector is the hook that will lock people into buying overpriced Apple/iBeats phones as long as they have an iPhone/iPad, even if they don't sound any better than the current Apple or Beats products.
Headphones are not simple, buy-some-raw-parts-and-wire-them-together objects. It takes a lot of engineering to get good results. Beats is a marketing company, not an engineering company. Companies like Beats put the emphasis on making the brand logo the focus of the design, not the performance or durability of the product.
I think that the Beats marketing people realized that their brand name, specifically, Dr Dre, is widely known to the crowd that shops at Walmart. That crowd doesn't know of quality brands like Sennheiser, Beyerdynamic, etc., because those brands aren't sold at Walmart. They've never heard quality headphones so they won't know they're not getting quality if they buy Beats. Therefore, the marketing people figured that Dr Dre could put out a headphone (a very low cost product to produce when you simply buy some off the shelf drivers and slap them into ear cups). Prominently display the logo on the phones in bright colors and you have instant marketing success and profits.
For the last 6 months all the daily deal sites on the web have had Beats phones on sale at steep discounts. They can do that because the things are such low cost to make products they still make a good profit even when they cut the price by 70-80%. Now that Apple has bought Beats, they're officially just another piece of iCrap. I wonder if Apple is going to prepend the phones with that stupid "i"... "iBeats" yeah, sounds about right!
Before you buy another pair of Beats (or iBeats), check out this site for better quality alternatives at the same or lower cost: http://thewirecutter.com/revie...
As soon as I saw the article I thought that it was just the sort of thing they had in Prometheus. It would be extremely useful for the military to be able to map out the inside of a building. Of course, you won't know what's behind closed doors, but they'll add something for that next.
Maybe they don't see it as robbing an unemployed person of a potential job. Maybe they see it as a way to keep their job, which for many, it probably is.
Yeah, that's what everyone should do- become and independent contractor. All those big corporations that employ thousands of people can start negotiating a fresh contract for each and every independent contractor they hire. And for engineers who do things like design or manufacture semiconductors, well, they can all buy their own equipment and hire themselves out as contractors too.
Oh, wait, they might have trouble getting loans to purchase millions of dollars worth of stuff, just so they can do their work.
Hey, I have an idea, what if large corporations hired people as employees under a more or less uniform contract? Then they wouldn't have to do so much negotiating, and people who do work that requires massive investment in infrastructure could do that work without having to own that infrastructure themselves...
Now I can hire myself out as an HR consultant and explain the benefits of hiring employees to big corporations!
When I am home my keys are in a box next to the door where I put them each time I come in the door. When I am away from home my keys are in my pocket or in my desk. It is NOT difficult to keep track of important things. It merely takes developing good habits. Good habits includes putting things away in places that make sense. I'm going to need my keys when I leave the house and get into my car, so the keys are kept at the garage door. It would be silly to keep my keys in a cabinet in the kitchen, for example, unless I entered and exited the house through the kitchen.
Obviously you can't keep keys in a single place at ALL times. Your airport security line is a good example. But how am I going to lose my keys in an airport security line? I put them through the machine and I pick them up on the other side and put them back into my pocket. Here's a simple tip that will save you a lot of panic at airport security lines: after you pick up your stuff, run through a simple mental checklist- keys, wallet, passport, tickets, boarding passes and then anything else you had to let go of for the security check, such as a laptop, phone, etc. To help remember, think about what you need for your trip- passport, ticket, boarding pass, wallet, and what you need if you don't go- wallet and keys. There, that wasn't so hard, was it?
I admit that I didn't always have such good habits,. When I was much younger I spent a fair amount of time searching for things that I should have known the locations of at all times. I learned from the time I wasted how not to be such a dope. I know of other people who seem to be incapable of learning such lessons. For them the device described might be good, if it works.
A classic example- old people in assisted living facilities frequently misplace their dentures (i know, what the hell?). They often take them out to eat (if they don't fit properly), wrap them in a napkin and leave them sitting on a table. The napkin containing the denture gets scooped into the trash with food waste and the denture has mysteriously disappeared. If WeTag's stuff works and the tag circuits could be embedded in dentures it would be great!
to keep track of things like your wallet and keys by habitually keeping them in a single place, you probably shouldn't be walking around with either anyway. You should probably be holding a real adult's hand when you cross streets, too. Using technology to enable people to continue to be dopes is not a good idea.
I can see where this would have value for people with dementia. If would help caregivers locate personal items that may be needed.
When I think about how many airheads are walking around, I can't help but think that if it works the project will make phat stax. I wonder if their target market will be able to find their credit cards to place an order...
That's the problem with/. Almost everyone here thinks that all engineers do is write software. I did various engineering activities when I was working- communications systems design for Motorola, RFIC apps for HP, analog RFIC design for Fujitsu and a startup called Stanford Microdevices, Back to apps for high speed SERDES and hypertransport chips at TI.

I believe rigid belief, as defined by you, is equivalent to ignorance.

4 rules for a successful work life:
1) Never stay at a job that sucks.
2) Never feel and "loyalty" to a company or boss- they won't hesitate to kick you to the curb if some accountant decides you're over paid or not needed. They have absolutely zero loyalty toward you, you should have none for them.
3) Don't worry about bouncing from one place to another.

Walmart sells iPhone 5c for $29 and 5s for $99. The last time I checked, Walmart was NOT the supplier of choice for hipsters.

I would not mind if it all just went away in an instant. It would sure save a lot of trouble.
