Aerospike Engines - Why Aren't We Using them Now?

Ashenkase says...

I followed the X-33 back in the late 90's and as mentioned in the video it was the composite tanks that sunk the ship. They kept cracking and it resulted in the overruns that tanked the project. It would be very interesting to build an X-33 type vehicle today with the knowledge and practical experience we have building and flying composite tanks.

A Perfect Circle -- Disillusioned

MilkmanDan says...

Lyrics from https://www.azlyrics.com/lyrics/perfectcircle/disillusioned.html :

(Dopamine, on dopamine...)

We have been overrun by our animal desire
Addicts of the immediate keep us obedient and unaware
Feeding this mutation, this Pavlovian despair

We've become disillusioned
So we run towards anything glimmering

Time to put the silicon obsession down
Take a look around, find a way in the silence
Lie supine away with your back to the ground
Dis- and re-connect to the resonance now
You were never an island

Unique voice among the many in this choir
Tuning into each other, lift all higher

(Dopamine, on dopamine...)

Willingly been re-wired by clever agents within
Looping our reflections, our obsessions draw us in
Fix and fixation, no sentience beyond

We've become disillusioned
So we dive like crows towards anything glittering

Time to put the silicon obsession down
Take a look around, find a way in the silence
Lie supine away with your back to the ground
Dis- and re-connect to the resonance now
You were never an island

Unique voice among the many in this choir
Tuning into each other, lift all higher

has rachel maddow lost her mind?

I can understand, it's not a simple issue, but this expansion happened 18-20 (invited in 97, members in 99) years ago. I simply can't grasp anyone being upset that NATO troops are in a long term NATO country.
If Putin/Russia hadn't been massing troops on it's borders, and then moving them into neighboring countries it now claims as part of Russia, the other bordering countries would not be asking for this safeguard, but to imply that NATO troops in Poland are somehow an attack on Russia is laughable. NATO troops would never invade Russia, that would certainly be WW3. As it stands, I feel like NATO probably wouldn't respond if it's troops were overrun by a Russian invasion of a member country, we (the US and others) certainly didn't help Crimea or Ukraine, even though we have a binding treaty requiring us to come to their defense, one paid for by giving up their nuclear arsenal.

Sadly, it's looking like there can be no stability/security in Europe with Russia either.

radx said:

Every expansion of NATO has been a hot topic over here, from the moment the reunified Germany joined NATO. We've attacked Russia twice last century alone and to betray them again in this fashion never sat well with quite a lot of folks, especially the old politicians who supported Willy Brand's "Entspannungspolitik" -- that's this guy.

To further illustrate my own stance on this, let me paraphrase Genscher and others: there can be no stability/security in Europe without Russia, and especially not against Russia.

Baby scared of pineapple! ...

Sagemind says...

Maybe so..., but in your description: "From http://boingboing.net/2014/12/15/baby-terrified-by-pineapple.html ..."

My point is not aimed at you, but the people naming these video in ways that don't represent what we are seeing, just for media hype and click-throughs. We all do it to an extent, but lately, It's been out of control, and apparently, it's making me edgy

"You won't believe what she does..."
"People are speechless when they see..."
"You won't believe what happens next..."

Facebook is overrun with these click farm posts.

Daily Show: Australian Gun Control = Zero Mass Shootings

ChaosEngine says...

@mram wasn't arguing for border control in the states. (s)he was saying that gun control in a specific area is meaningless if you can trivially circumvent it by driving for half an hour.

To be honest, I really don't know what the solution is. I genuinely think the problem in the USA is not so much guns, but your attitude to them.

In the developed world, plenty of other countries have lots of guns, but only in the states does this cowboy attitude with guns prevail. I have plenty of friends with guns, but none of them have them for "home defense". The very idea that I'd need a gun to protect myself is alien to me. It's the 21st century, not the wild west.

Possibly the genie is out of the bottle in the US. The argument of "gun control just means that only criminals have guns" might well be true. But if that is the case, how is it that countries like Ireland or New Zealand where even the police force don't carry guns* have lower firearm homicide rates (~1/10th the rate of the US). Surely we should have been overrun by lawless gangs of armed criminals while the police stand helplessly by?

*NZ Police do have access to firearms, but they don't carry them as a rule.

Jerykk said:

Do you really think individual states will ever have that degree of border control, if any? Let's be realistic here. And if border control hasn't been able to stop the flow of drugs from other countries, why do you think they'll be able to stop a flow of guns?

Tommy tsjotomayor condemns knockout game!!

shatterdrose says...

I'm sorry, but those conclusions are pure emotional based off what you see in the MSM. If you can find me a study, a legitimate one, not one from Faux News or Huffington Post, that actually shows that a government safety net induces vagrant behavior, then I will believe you. Until then, I will stick with all the studies that show very clearly that social safety barriers do in fact work, and that the decades old gutting of the programs are wrecking havoc on the system. Not to mentioned the systematic desecration of the educational system that's been designed solely for "efficiency" and pumps out students that are over qualified, unhappy, massively in debt and lead to believe a lie in which they can never achieve, or the exact opposite and ditches those most in need yet are the most visually different.

Combine this with white flight, red lining, and a culture of fear mongering, race baiting and rapid communication and we have a perfect storm. The general population is so overrun with sad stories and empathy inducing situations they actually go into empathy shock - a state in which they cease to care and numb themselves so they don't have to make a decision. A decision which they may later feel bad about. Instead, it's "nothing I can do about it so I won't care." And yes, this happens with those "gang-bangers" you talk about.

Instead of solving the situation, which is a blatant and total discrepancy in incomes, social normality, and general empathy, we will continue to have this problem. So long as white flight occurs and the NYPD openly racially profiles and harasses 110% (no joke) of the black community, and so long as the Christian Right still chants "it's ok to profile brown people" both in NYC, Arizona and everywhere else we will continue to have this problem.

Ever hear of the Theory of Attitudes? Or Reactance? There is far more going on than "if we give them money they'll stop working." Because I'm pretty sure every Christmas when your parents (general assumption) gives you presents, you instantly stop working. Totally proven concept, eh?

Uhhh, maybe you needed the sarcasm button for THAT statement. What's "factual" is the end result all over the fucking televison and internet, a national case-study of how to fuck-up a generation of imprint-able minds. Whether the scenario TC layed-down or a dozen others from the same petri, what do need, a diagram, a dozen "expert" analyses in the form of published thesis or someone YOU trust to make the leap??

Red Letter Media Talks About Prometheus on DVD

gwiz665 says...

There was a clear problem in that you didn't care for any characters. The most likable character was the homicidal robot, which is a failure in my book. In the original Aliens, you grow to like Ripley and you like the camaraderie going on in the beginning of the movie, even if most of them were fucktards. The marines in Aliens were also likeable, even if you sorta recognized them as the dickheads from high school - some of them were our hook into the world, ripley, hicks, hudson all good. Even in alien 3, you still ahve ripley to hang on to, even if it's a desolate despairing film. Alien 4 you have Winona Ryder-robot to like, where ripley is more.. well, alienated.

in prometheus, I liked the Captain Janek and in a twisted way Fassbender-bot, because he was played well. All their motivations didn't make all that much sense though. I hated Holloway, hated Shaw, hated Vickers, fucking hated all of them. Gah, it's so irritating, because the universe of it is so interesting! aaargh.

I think there could have been a much better movie with the same source material, I think the concept could be really cool, but it's beyond a simple reedit repair job. The characters need a total rewrite to not be selfish, unlikable fucktards. There needs to be a lot more explanation and more time spent soaking in each of the more important subject matters and not this jump from one scene to the next with no flow and no reason.

I don't know. It seemed like it needed more "epicness". Like you said (or, as I understood you), more time for the viewer to parse the implications of the much bigger picture before they throw up a scene of some slimesnake tickling someone's uvula. Maybe a scene where they just stand around and go "OMFG! We've discovered the greatest discovery in the history of mankind! Oh, shit! That's a fucking alien structure! The first one ever discovered!! This is fucking amazing!!" They just didn't seem too impressed with anything. And I wish they had left the Alien stuff out completely. They didn't need it. There's just a bigger, better story here than the one we've already seen again and yet again in the sequels. Most of the characters did have that ST:TOS red-shirt aura about them, and really served little purpose outside of biting it in creative ways. Could have been better, but I still dug it, and I think the sequel(s) has a chance to be great. I just hope the Engineer homeworld isn't overrun with alien queens or some dumb shit like that.

Underwater Explosions - Smarter Every Day

ReverendTed says...

My initial suspicion was the same as the host's - that the bottle was rocketing up and the cap was "overrun" by the rest of the bottle. That doesn't hold up to scrutiny since the cap "shrinks" back rather than staying still.

In their first explosion, the cap actually explodes very quickly after the burst. That seems relevant. I'm not sure how.

My second thought is along the "vacuum\low pressure" line of thinking. The entire bottle is pressurized in the instant of the explosion, and then ruptures at the bottom, so now the bottom of the bottle is lower pressure as water is rushing out, pulling the cap end down. Bernoulli principle, perhaps?
I imagine a bottle full of water, but it has no bottom. The water is rapidly and forcibly evacuated. The logical thing is for the cap to be crumpled downward.

Ooh, wait. Could this have something to do with the gas at the top of the bottle vs the liquid? I'm having flashbacks to the Mythbusters episode about the sinking car, and how the pressure of the water inside the car was lower than the outside as long as significant amount of air was left in the vehicle, so even though the water was up past the inside of the car door, it still couldn't be pushed open until the rest of the car had equalized. This seems relevant to me as well, though I'm not sure how, exactly.

How To Sit Behind Mitt

NetRunner says...

People in the press liked McCain, and had this preconceived notion of him being some sort of independent "maverick". Since Republicans don't really tolerate independent thought, he had to work really hard to convince them that he was done being independent and would be a hardline conservative, and in the process turned himself into a laughingstock.

Mitt Romney seems to have been hated by basically everyone, seems to have zero personal charisma, is completely out of touch with how normal people live their lives, and it's virtually impossible to find an issue on which Romney hasn't been on both sides of during his political career. It's not really a surprise that he's a joke right out of the gate.

If Romney wins, it'll be a signal to the rest of the world that America is either no longer a democracy, or is now so completely overrun with people who have no grasp on reality that it probably shouldn't exist anymore.

And I honestly think there's a 40% chance Romney will win, because there's an awful lot of people with no grasp on reality here...

>> ^raverman:

Is it just me or is Mitt Romney a laughing stock before he even starts campaigning in earnest?
I don't remember people making fun of McCain like this (or much at all until the Palin twist)

A new low for TV science: Malware Fractals in Bones

No scanner would see a program in an image, realize it's an executable and execute the program all without the user's knowledge.
It's barely possible that you could transfer a workable program that way through fractals, and the people on the other end would have to spend weeks or months decoding the program before they could make it run IF they could figure out what it was in the first place.
pattern might be constructed in such a way that when scanned it can confuse any piece of software in the chain to cause a buffer overrun, at which point they could craft the following data to actually be executable and contain malware payload.
This is kinda what happened in a few instances of MP3-based viruses. MP3 file's metadata was malformed in such a way that it would crash the player and execute trojan payload that was embedded in that MP3 file.
Look up information about MP3Concept(MP3Virus.Gen)
There was another incident that involved MP3 file played in Winamp player. I can't find link about it now.
So while realistically unlikely, it's possible.

The main difference there being that the MP3 was a digital file which had been manipulated, not a sound recording. The file was corrupted in a very clever way. In the show the bone 'picture' was taken by the forensics team. They did not bring in a file the guy had created, they took a photograph. You can't insert corrupted data, because the data is coming from the camera they own.
you've never had a legitimate program crash while working with a legitimate file? this is when malware gets to do its stuff.
