They import 2/3 of their energy (including nuclear energy from France and Czech Republic). They are the fifth largest importer of oil. Over 70% of their domestic energy production comes from fossil fuels.
They of course shut down their nuke plants and are building lots of renewable energy plants, but that's far from the full story.
My 7 year old daughter really enjoys code.org. The puzzles are fun and the site works great on her HP Stream that she got for xmas. Having her very own computer also helped and that laptop was well worth the $200.
My spouse is a lawyer. Last year our two home printers totalled over 20,000 pages while working from home some evenings and weekends. Sometimes both printers are busy at the same time.
We read books on kindles to save some trees.
I've seen many middle-school kids lugging around backpacks that weigh almost as much as they do. Is that really necessary?
Yes, it is. It's called exercise. And after completely destroying physical education, to protect fat kids from being heckled, it's the last bit of exercise kids get nowadays.
Did you see the speed in the video? That thing goes at max 10mm/sec. I print at 100mm/sec, no skipped steps.
At some point, there are just limitations. For example how much plastic you can melt through the hotend.
With speed you also face the biggest evil of 3d printing right in the face: acceleration. High acceleration is what makes a good print. More speed, more inertia, crappier prints. In fact skipping steps has not much to do with speed, and a lot more with the lack of acceleration.
While it sounds like a cool project, using servos instead of steppers is just a bunch of added complication, cost and downsides.
But first, let's be realistic: we are extruding plastic at several 0.1mm width. For example a 0.35mm nozzle has to lay down plastic at a minimum of about 0.4mm width to achieve good layer adhesion. So having 4096 steps per rotation on a servo vs 3200 steps on a stepper (200 steps * 16 microsteps) will make zero difference. (Although higher microstepping is also possible at the cost of power output and processing speed.)
Then you add a whole bunch of electronic components, increasing cost and failure points. Brushes in servos wear out, needing replacement. And I'm sorry, but some cheapo small servos from RC cars will not be a replacement for the beefy steppers used in even the cheapest 3d printers. BTW, servos are a major point of fail in RC car, and a decent servo costs several times that of a nice stepper.
Let's also think about what happens if there's a mechanical failure that would trigger a step being lost, for example a stuck bearing. A stepper would simply stop working. A servo would not stop until the encoder wheel reaches its position, so without some added safety system the servo would just commit suicide, burning itself down or chewing up its gears.
Having said all this, my current reprap printer has yet to skip a step after several hundreds of hours of print time. So looking for a solution to a problem that doesn't exist?
sure. until you don't get that text message from your daughter, crying for help. text messages are not some freaking candy crushing toys, for some people life and death. so yes, apple better get their shit together and fix their mess.
the solution is quite simple. don't fuck with people's text messages, stop rerouting them to imessage or icloud or whatever icrap is the vogue marketing blurb of the moment.

"reusing them has to become a standard"
Because cleaning and sterilizing bottles happens through magic. No water, bleach or other cleaning agent is necessary.
"If I were King"
Then you'd have magic. But you're not and you don't.
So what is your suggestion?
Oh yeah google? Really want https everywhere? How about start signing some SSL certs for free to put the mofreking CA mob out of business?
This is another step towards systemd becoming a complete OS.
Or maybe Germany is awesome at propaganda.

Good luck with that, viagra does not make you horny.
That's not what she said.

You mean candy crushing?

So go on ahead, take this away, too.
the wii part of the previous generation of consoles? as in ps3 and xbox360?
no way. i'd put it in the ps2/original xbox league, with a useless gimmick controller. and probably even that's a stretch.

what's with the onslaught of kickstarter "stories"? we get at least one a day recently. did kickstarter sign up for the premium slashvertisement plan?
I had both moto and samsung phones, and was happy with both manufacturers. Neither locked up ever. I think you are just making shit up.

chill out. it's just a freakin' game!
it will be shit, just like episodes 1-3. except more masturbatory cg fx. but it will make shit loads of money anyway.
it's trying to control all those freaking balloons
now that wasn't too hard to predict, was it?

your daughter also willingly clicked on that craigslist ad and also willingly got into that black car before she was last seen.

Let's also see which one fits in your pocket, making it available at all times.
Or, wouldn't you be happy with a sip of the $10 wine from a flask if you can't carry the $100 bottle around?
