Rheinmetall Air Defence

A cloud of tungsten projectiles... clearly (hopefully?) not intended for use over populated areas, though I suppose it could still be preferable to whatever might otherwise get through. Would be a hell of a messy hailstorm resulting from this thing though!

Thorium Powered Car, Drive nowhere for 100 yrs on 8g of fuel

chingalera says...

Lotta Lithium there as well, and I believe a tungsten deposit er two that ain't tapped-out...Not to mention that sweet, sweet poppy, of which I understand there is a BUMPER crop this year what with all the army guys scootin'-out.

Romney silent on climate change

ctrlaltbleach says...

I don't really know with a 100% certainty that humans are 100% responsible for climate change but I do believe that we do create and are creating an impact. I don't know the science behind it but when I see that scientists tend to believe it is real and is happening I have to give that credibility because who would know better than they? What I think is even more important than climate change however is it's big brother sustainability. I bet the people in the audience would chant U.S.A. to that question as well. Mainly because people are afraid of the answer to that question and they would rather pretend it doesn't exist. I believe they think the present is more important than the future. But, when helium and tungsten prices start shooting through the roof and people are no longer able to afford to blow up a balloon for their kids birthday and light bulbs start steadily rising in costs these problems will no longer be avoidable. I think that is what scares me most about this video is we could be doing something about it now.>> ^bobknight33:

There is climate change then then there is Al Gore and the leftist man made climate change.

Man made climate change theory is pure BS. Only fools believe this.

Any Sifters bought an iPad? (Blog Entry by dag)

Hang on here. Let's be fair. I don't know who invented touchscreens or pinch to zoom or whatever and I don't much care.
But it's Apple who have come along and made mobile devices that are nice to use - very nice. No one else was rushing to take a chance on making an iphone. If it wasn't for them I reckon we would still be stuck with devices like my Nokia 6680, which is admittedly rubbish and with each passing day becomes more annoying to use. I've stuck it out for ages but gradually, very gradually, I can hear the call of an HTC Desire.
Before this I experimented with a Palm Tungsten PDA - overall it wasn't great. You had to use the stylus and learn that grafiti thing. And there was no itunes equivalent, no desire to connect with the customer and installing programs was tedious and would be buggy when you did. It didn't make me productive and it wasn't much fun either.


The iPhone is no doubt a nice phone, but it's not exactly like Apple invented the wheel here. In any case, I thought this thread was more about the iPad and whether any of us would buy it. I have to confess that I don't like flash, but even I have to admit that it's become part of the web experience. Somehow I feel the iPad would be great for things like playing Hapland on your couch, but obviously Jobbo takes it personally when it comes to Adobes format and won't allow it.

With the far superior Asus tablet coming out next year there's absolutely no reason for me to buy the iPad. Besides, I'm trying to get away from buying products of corporations that are into torture and restriction of free speech.

Isn't the digital landscape that more fertile for everyone now thanks to Apple?

@Farhad2000 - just to be clear there's no way they're forcing you to buy their products. I'm not using any - the limitations just rub me the wrong way.

I would also posit that the same thing has happened, albeit in a smaller way, with the iPhone and iPad. finger optimised UI, Flick to scroll, bounce back scrolling, pinch to zoom and more are innovations out of Apple's skunkworks. These innovations exist on Android and Pre phones - but to assume that this would have happened without Apple is naive.

Nope sorry, Apple did not "invent" all of these things. I know about flicking and pinch to zoom being around before the iPhone, there's even a video of a desk-sized tabled demo employing those tecniques around here, but I can't find it right now.
Good thing Apple did not invent the mouse cursor, or else we all would have to use some weird thingy like a crosshair or sth because you can bet your ass they would've patented it.

Golf ball deformation at 70,000 fps (!)

jubuttib says...

>> ^mxxcon:

isn't center of the golf ball actually a solid mass? so while surrounding might deform, center remains...that video is highly questionable. i doubt even a tennis ball would deform like that


Depends entirely on the ball in question. Some older balls had a small solid core with rubber string wound around it. There are balls that have for example a tungsten core, but most balls on the market today are just a large urethane blob with a (often titan infused) cover. Some higher end balls have multiple layers in the core.

Oh yeah, golf balls also hold the current ball speed record in sports, after Jason Zuback managed 204 mph on an episode of Sports Science. Old record was a 188 mph Jai Alai throw.

Chrome Speed vs Potato/Soundwaves/Lightning

Seric says...

YT:
These speed tests were filmed at actual web page rendering times. If you're interested in the technical details, read on!

Equipment used:

- Computer: MacBook Pro laptop with Windows installed
- Monitor - 24" Asus: We had to replace the standard fluorescent backlight with very large tungsten fixtures to funnel in more light to capture the screen. In addition, we flipped the monitor 180 degrees to eliminate a shadow from the driver board and set the system preferences on the computer to rotate 180 degrees. No special software was used in this process.
- 15Mbps Internet connection.
- Camera: Phantom v640 High Speed Camera at 1920 x 1080, films up to 2700 fps


"Why does allrecipes.com in the potato gun sequence appear at once, and not the text first and images second? And why does it appear to render from bottom of the screen to the top?"

Chrome sends the rendered page to the video card buffer all at once, which is why allrecipes.com appears at once, and not with the text first and images second. Chrome actually paints the page from top to bottom, but to eliminate a shadow from the driver board, we had to flip the monitor upside down and set the system preferences in Windows to rotate everything 180 degrees, resulting in the page appearing to render from bottom to top.

"Why does the top one third of the page appear first on the weather.com page load?"

Sometimes only half the buffer gets filled before the video card sends its buffer over to the LCD panel. This is because Chrome on Windows uses GDI to draw, which does not do v-sync.

"The screen wipes are so smooth - how was that achieved?"

The screen wipes up in a gradated wipe because LCD pixels take around 10ms to flip and gradually change color.

Colbert: We Have A Death Star!!!

Xaielao says...

So we have a Death Star.

We are building space launched tungsten rods that enter earths atmosphere in minutes and slam into an area with kinetic force similar to that of a nuclear bomb, sans the radiation.

We have missiles so accurate they can shoot down other missiles and even satellites.

We have rail guns mounted on warships that reach their target in seconds and wipe it off the map.

Dave Chappelle on Dr. Katz

choggie says...

Always thought superman could use some sense. You are smart enough to realize yer stronger, smarter, faster, and healthier than those in yer "charge"...and you get all disillusioned about yer dad's plan for ya, and wish you had taken the ride to oblivion on Krypton with yer own kind...so you what????...Get a freekin' job as a nerd at local paper??! Fuck that.

Superman hadda lotta jobs, before he decided to let the human race destroy themselves...He was the strong man once at a state fair in Kansas, who got bored real quick, with bending titanium and tungsten rods for the crowds a monkeys, stuffin' their faces with corn dogs and funnel cakes...

Extremely bizzare old video on magnesium fire properties

9/11 Mysteries-Fine Art of Structural Demolitions

cryptographrix says...

SaNdMaN: Interesting parody, but a completely different scenario unfortunately - a head on collision between two objects of different densities at different speeds is completely different than the weakening/melting of steel with kerosene. It's like trying to compare driving your car into a block of ice with lighting a kerosene fire in the car.

Without another accelerant like Thermite/Thermate to raise the temperature of the fire, much of the metal components will survive, structurally. They won't look too nice, but the car's roof and frame will stay in place(assuming that you have an older steel-framed car, and not an aluminum or other alloy framed car[unless of course your car somehow has a Titanium alloy or Tungsten alloy frame or whatnot, which I don't know of any that do, but it's a nice thought]).

Of course, many cars have plastic based bodies, so the roof itself might not stay in place, but the frame shouldn't have too much of a problem.

Last I knew, the exterior of the WTC buildings were not made out of plastic, so there's really very little chance of a fire causing their destruction.

Actually, they caught on fire before, even, and didn't get destroyed(unless we somehow rebuilt them and I wasn't aware of it).

Of course, now I'm just ragging on you - sure, it's POSSIBLE(through such theoretical physics as Quantum Mechanics and whatnot) that kerosene could have caused the WTC buildings to collapse - making them the first, second, and third steel and concrete buildings to collapse in the recorded history of the planet, but the probability of it actually happening is about the same as the probability of you being able to push your hand through a solid steel plate without any resistance - sure, according to Quantum Mechanics, it COULD happen, but, well, how many times have you leaned up against a building only to find out that your elbow was half-submerged/half-merged with the brick and mortar?

To date, I know of only one person who can achieve this effect - a guy by the name of John Hutchison.

He uses something like 6 or 8 Tesla coils to do it, too, and if 6 or 8 Tesla Coils big enough to surround the WTC complex were around them that day, well then I probably wouldn't be arguing that the destruction of the WTC complex was not caused by just the planes alone...then again, it'd be way too obvious that the planes were not the only causes of their destruction that documentaries such as this one wouldn't be needed....not to mention the power requirement that'd take....lol

So yeah, get a solid steel plate and practice pushing your hand through it - let me know when you're able to, and I'll consider taking some of the things you say seriously. According to Quantum Mechanics, it's possible, and so long as you believe it's possible, well you should be able to prove it, huh?

Have fun!
