AsapSCIENCE - 3D Printing will Change Everything

Psychologic says...

Yes, you can (part by part perhaps), though there's at least one 3d printer that costs under $100.

Right, but can I 3D print a 3D printer? If I'm paying $2.2k, I'd like to recoup that by selling a copy of the thing I just bought.

I view it on my tablet sometimes. It isn't huge problem since I can just reload the page to get a different ad, I just thought I'd let you know about it.

Sorry I don't think there's anything we can do about how the ad is being rendered on your phone. Have you tried using the mobile version of the site? It is much more suitable for your phone (and doesn't have any ads).

You can load the mobile version on any page by clicking the link in the page footer or you can just put "m." before videosift.com: m.videosift.com

Hey, I'm having an odd problem with an advertisement on android. The Amazon ad (square on right side) clickable area seems to cover 90% of the screen, including the video. The ad displays normally, it just prevents me from clicking on anything.


I have"t had this problem with any other ads. Zoom level doesn't seem to affect it.

Theoretically yes, but the efficiency would be terrible with current tech.

If only relying on radiative cooling then the condenser would need to be huge just to cool something the size of a house. Of course, the hotter the coils, the more heat transfer there would be.

Then the radiation would need to be transmitted through the atmosphere. That would heat some of the air along the way, reducing the efficiency of the transfer and further increasing the amount of cooling needed to offset global warming (clouds wouldn't help either).

There's also the fact that the entire process consumes a lot of power to compress the coolant. Currently much of that power comes from sources that emit greenhouse gasses, reducing the net efficiency of the cooling offset. The machinery itself also creates heat, which would need to be offset with additional cooling.

I don't think her idea was "stupid"... she just doesn't understand the difficulties and cost involved. If we had unlimited solar power and extremely efficient large-scale AC farms then it might work, but there's also the unknown side effects of localized cooling on wildlife and the hydrological cycle.

It's a neat idea, and I'd love to run the numbers on it sometime for fun, but it's currently impractical and possibly counter-productive with our current capabilities.

Ordinary air conditioners could only increase global mean temperature due to the law of conservation of energy. But if the condenser coils are in a vacuum surrounded by glass on top and a mirror on the bottom, then they just radiate into space.

Don't know, but there should be something in options that lets you choose which keys move your character (or at least tell you which ones do).

Generally it's W,A,S,D.

next time play amnesia: the dark descent, you fucking pussy.

I thoroughly enjoyed that game... played it with headphones and no lights on (as intended).
The atmosphere was wonderfully effective, and not just in a "suddenly startled" way. Unfortunately it lost some of that atmosphere towards the end in favor of depicting torture, but it was worth playing either way.


I downloaded the trial for that but couldn't actually move my character. I tried all the keys. What was I doing wrong? (I'm not much of a PC gamer)

If I start lending it out then I'll just lose it again!

Usually if I find myself typing a lengthy post I'll stop myself and try to think about the subject from a different perspective. After two or three attempts I can usually get a pretty good idea of what is needed and what is fluff.

On the other hand, if I can't cut it down to a manageable size I just end up not posting. I think it mostly comes down to thinking of efficient and appropriate examples to illustrate an idea, which is deceptively difficult. My success in that regard depends greatly upon the subject.

Also, I've worked in public relations and teaching jobs dealing with people who tend to glaze over if I take more than three sentences to describe anything, so that may have something to do with shortening my posts. =)

How come you can easily sum up in 2 short paragraphs what it has taken me, and failed in me, 5 comments of walls of text! I hate my brain, can I borrow your's from time to time?

Statistically speaking Gods do not and can not exist.
[...]
Some statistics are absolute. The probability of a deity existing are finite:infinite. In other words 0.


By that logic humans can't exist, because the probability of any specific individual you could imagine existing is practically 0.

You can point out a lack of evidence in the existence of gods, and I would agree with you on that point, but statistics cannot disprove the existence of something.

If you want to think of it in mathematical terms... 1/X approaches zero as X approaches infinity, but 1/X cannot equal 0. You can't just divide something by infinity and proclaim it is therefore impossible. Mathematics do not work that way, goodnight.

Pi Is (still) Wrong.

Psychologic says...

Pi vs Tau reminds me of Qwerty vs Dvorak... the small gain in simplicity (or typing speed) is more than offset by the burden of the change, and learning to use both would be more confusing than using the current standard.

I'd be fine with the change, but I think π is cuter. =)
