Yeah, you could have so much evil fun.
Probably give people real heart attacks :D

We interrupt your regular browsing of insignificant things for a live view of the Earth from the ISS:
http://eol.jsc.nasa.gov/HDEV/
In HD too!
Absolutely must see - it even shows exactly that its over.
For the next half hour or so its over the day side of the earth so things are visible. If its dark when you watch come back in half an hour and it will be light again, because the ISS orbits many many times a day.

I clicked to watch, but it was over the sea... meh.
Still, very cool :)

Polaris 2014-05-09 10:46

I don't think it's over the sea now, but I can only see the top of a big white ball... Maybe I should wait until the night :-/
Still, very cool indeed !

Darkflame 2014-05-09 13:34

ISS orbits the earth every 90 minutes or so, so every 45 minutes or less it will be in daylight.

*bump*

Autodesk made a virus from scratch:

Its not a computer virus O_o

Darkflame 2014-05-30 20:11

Not nearly as important as the above, but certainly in the crazy cool catagory;

A farday cage dress...

synced to the music of "Hall of the Mountain King"
O_o

Polaris 2014-05-30 21:22

No way :lol:
Is there a vid of this ? This looks so weird :hmpf:}-)

marcosmapf 2014-05-30 23:18

Lol that looks super funny :lol:
Could you post the link?

Darkflame 2014-05-31 01:41

The article I linked too has two videos in it - although they arnt that clear.

marcosmapf 2014-06-01 00:50

That's a nice interview they got there. That designer has done an amazing work with all her dresses, they are all very well thought. The Truth or Dare dress is awesome :p

Polaris 2014-06-01 23:36

Found this
Not exactly the same, but nicely filmed.

Darkflame 2014-06-02 01:02

It really is the perfect music to use for it.

Darkflame 2014-08-07 22:33

A ship yard is fitting its workers with Exoskeletons;

The future folks. We have arrived.

SpaceGuitarist 2014-08-07 22:41

Impressive.

Polaris 2014-08-08 00:02

Wow. I want one to jump super-high :D

Darkflame 2014-08-08 00:49

Theres been some other cool/bizarre/tentatively very important news.


Quote:

Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma
http://ntrs.nasa.gov/search.jsp?R=20140006052

Basically Nasa has confirmed a positive result from what was previously thought to be a rather crackpot idea; propulsion without propellant.
Originally a British guy was claiming to have invented an engine based on this principle, then latter a Chinese team claimed the same result. Both dismissed by and large. But Nasa also detecting something is now putting pressure on everyone else to look into it.

For sure, the impulse detected is tiny. But given that it seems to invalidate conservation of momentum, if true its pretty incredible.
Useful for space travel too; Even really slow acceleration is useful if you can run your engine 24/7 on solar for years without running out.

Now, theres a lot of sites both hyping this, and a lot of them dismissing it too. But the thing is, when those groups are random Internet commentators, its probably best not to bet against the actual rocket scientists.

Sounds like something I've been looking into myself these last couple of days, the VASIMR: http://en.m.wikipedia.org/wiki/Varia...oplasma_Rocket

Darkflame 2014-09-21 15:41

This has to be the invention of the century;
http://hackaday.com/2014/09/17/the-abovemarine/

A touch of futurama about it :D

Polaris 2014-09-21 20:57

Whoa... Impressive, I wonder how much is the fish actually comprehending... Is it thinking that it's just swimming around or...

marcosmapf 2014-09-21 23:02

Polaris, he is at least comprehending that the direction he swims actually influences the direction that the aquarium moves, or else he wouldn't do things like he was doing in the video.

Still, that's realy cool! To know that fish can learn things like that, its amazing. Maybe they can learn even more complex things? Who knows.

Darkflame 2014-09-22 02:10

Well, theres always a chance that the video was selectively edited.
But it doesn't seem implausible to me, fish certainly respond to fingers if they are very close to a tank.
I am not sure however, optically, how well a fish in a bowl looking though glass and air can see the world. I'll have to stick my head in a fishtank sometime :P

Still, you could do some cool experiments. Could you train it to go to a certain area for feeding? Have a little food dispenser that sprinkles food when its pushed?

Polaris 2014-10-08 15:17

Kinda off-topic... This is very low-tech...

"The nine planets" :lol: encarta has gotten so old now.

Darkflame 2014-10-08 16:03

Well, actually...

http://www.al.com/news/birmingham/in..._your_chi.html

I'll just say what I have always thought; Leave planet as a relative or cultural term, and use something more precise for scientific definitions.
I see little reason why the 3 characteristics they picked - which have arbitrary boundaries anyway - are useful for science when combined. Its like if fruit was defined as "round things which are nice to eat" rather then having anything to do with their origins or composition.

Just have a separate class system that can assess a few characteristics separately.
