Stripping the paint off a car with a 1000 watt laser

charliem says...

Lasers have a pretty amazing attribute where you can use a wavelength that is only absorbed by certain materials, leaving all other materials entirely untouched by the photons (as they have a very high reflectivity or transmission index for the wavelength).

No idea whats going on with this system, but its possible they are using a colour that is optimised for maximal paint absorption (heats up the paint the most), whilst at the same time maximal metal reflection (doesnt transfer any energy into the metal).

I was thinking the same thing. No physical force, but I can imagine it's very easy to build up heat with this thing.

Mountain Horse Bike Conversion Kit

ChaosEngine says...

Sorry, it's completely irrational but I hate everything about this.

I go into the backcountry to ride untouched snow, to get some peace, for exercise, to challenge myself and as trite as it sounds to "get back to nature". This feels like the antithesis of all that.

It's unfair, but all I can think about are lazy idiots who don't know what they're doing coming into an environment that could kill them, ruining the snow for those of us that actually worked to get there and to top it all off, they're on loud, carbon-spewing bikes.

Yes, it's completely prejudiced. Some of these guys might be backcountry gods looking to scope epic lines, but please, just this once, can't they fuck off and leave something beautiful alone?

And yes, I'm being a selfish judgemental asshole. And yeah, part of it is because they can cover in a few minutes what would take me hours. Don't care.

I won't downvote because I realise how childish I'm being, but that's my reaction to it.

Russell Brand to Jon Snow; "Listen you, Let me Talk"

Sagemind says...

Fair enough..., I've never been through a revolution...
I just know that when the system has passed the point where there is nothing anyone can do to steer it back, then the system needs to be kicked, because those corporations in power aren't giving it up willingly.

Yes, Occupy absolutely failed. I had no illusions it would ever bring about change in any form...) And it always will as long as the guys in power have control of the government, while hiding behind their untouchable walls.

ChaosEngine said:

I think Brand is in general, a reasonably funny guy who doesn't have a clue about politics, and should shut the fuck up about hand-wavy, airy-fairy notions of revolution without anything solid to back them up. I disagree with @Sagemind. Revolution is meaningless without a goal. That's why occupy failed (and if you think it didn't fail, please enlighten me as to what they actually achieved).

Destruction can be a wonderful catalyst for change. You can't make an omelette, etc. But if you don't actually make an omelette, all you're left with it is raw eggs and shell.

Now, all that said, Brand is completely in the right here. He actually knows what he's talking about when it comes to drugs and in particular rehabilitation from them. Current drug policy is an abject failure by every metric imaginable.

And Snow should know better. As hard as it is for those of you accustomed to the likes of Fox and MSNBC, he's actually a respected journalist.

Man Sues: Non-Employment Condiseration w/Police for IQ

Cue Don LaFontaine voiveover:
"Imagine a world, with an untouchable minority of elite who make the laws, private armies outside of these laws, and robotic, hind-brained minions to enforce that law and corral the interred.....If you are not part of one of these three groups.... (cue moans, screams, slamming cell doors-montage)

Then you are....part of the problem.....PLANET NOW!. (coming soon to the theater of every city on Earth)

Questions for Statists

JustSaying says...

But who will beat that woman to a pulp and sell her as a sexslave to a disgusting old pervert?
Someone who likes to trade goods freely without government intervention. A true libertarian. Like the great Humungus.
But wait, she's got a shotgun. It'll make her untouchable in that Mad Max Utopia of hers.

The Natural Effect or How False Advertising Has Conned Us

shatterdrose says...

Cross-hybridization is one thing. Patenting a cow you found in Africa and then suing the life out of the original tribe is the Monsanto way. Or, changing one gene and then claiming ownership of all corn in the US and then suing small farmers when their crops get contaminated (and of course, denying it) is GMO. The fight against GMO isn't always a "health" concern about wanting to stay truer to our millions of years of evolution and cohabitation with certain foods. It's also about fighting against mega-corperations that unfairly target small farmers with regulations such as requiring white painted walls . . . yearly, or requiring an office and bathroom for a health inspector to use once a year that no one else can use ever, or so many laws and regulations that a small farmer can inadvertently break the law, steal someone's intellectual property and be sued out of existence all while doing the same thing their family has been doing for over 100 years.

When we plant crops of only one variety over large swathes of land we invite disaster. It's already happen numerous times. Hell, no one remember deadly spinach killing around 50 people with no way to trace the origin? Mad Cow? Or the destruction of economies in their world countries because Monsanto requires only their crop to be grown and subsistence farmers into the ghetto's of India so that more High Fructose Corn Syrup can be made.

Or worse . . . the US Farm Bill . . . *shivers*

So no, it's not always about health. It's about staying true to the roots of a society that worships our farmers as life-givers, essential to our health and economy and free of unknown risk that could catastrophically damage the world as we know it all while ending a giant untouchable monopoly that refuses to let even the tiniest bit of oversight oversee it's operations so it can continue to "own life."

D. Simon: Capitalism can't survive w/o a social contract

radx says...

The basic form of a social contract is the foundation for every state in the world. Every individual within the territory forfeits a set of rights and is imposed with a set of duties instead. That's a social contract as described in Jean-Jacques Rousseau's "Du contrat social".

Doesn't help much with regards to Anglo-Saxon capitalism, does it? Beyond its most basic definition, social contract means, in theory, a recalibration of metrics beyond mere profit, within a society. Whatever metrics one might think would reasonably map progress towards the ultimate goal: the pursuit of happiness.

A concrete example would be the political-economic system of Germany, 1948 onwards, the so-called "Soziale Marktwirtschaft", wherein capitalism is (or was) constrained by agreements to the benefit of the whole of society. Not any individual, not any group, all members of society. Manifestations of it would be the safety net in all its forms and shapes, the health system, the pension system, the rejection of military interventionalism, the preservation of nature, no tolerance for fascism, etc. All specific policies that have their origins in an understanding of what society agreed upon would be best for everyone. The extent is subject to constant political debate, but the underlying concept remains untouched.

So the claim that there is no such thing as a social contract strikes me as a continuation of Thatcher's insistence that there is, in fact, no society. I don't subscribe to that notion, and as far as I can tell, neither does continental Europe as a whole.

If people prefer a system without a "society" beyond the very basic neccessities of a functioning state, go ahead. Do your thing. Competition of ideas and whatnot.

But I'm going to stay a member of this society, thank you very much. And as such, I take the liberty of leaving this "discussion" again. Cheerio.

The Heist that Changed History

chingalera says...

...and those programmed to be left-leaning are as distracted by bread and circuses as the worst of the clueless right-The real power comes for the left if gears change and the focus becomes financial institutions and political lackeys who fool you into thinking your power is in a vote or a cause-They hook you with bleeding-heart pet-causes and the distraction continues-

There is no stopping the insanity of a world controlled by a hi-jacked economy and you are powerless unless this becomes the focus of all activism. The FBI is untouchable today, as well as the surveillance infrastructure. All these pieces of the puzzle become powerless when you stop paying attention to the farcical slave-economy and the coming world police state.

The real success of programming shagen, comes from each generation becoming thicker, stupider, and programmed to be slaves for shit-tickets to buy more 'stuff' with.

All you need is food and love babies, and they have almost cornered the market on edibles that are not toxic for body, mind, and soul.

The shit they are capable of today makes Cointelpro look like a kindergarten spelling test.


Wholly disagree with the idea that the exposure of Coinitelpro caused the government to "reign-in" a GODDAMN thing. They simply do what all failing or exposed nefarious empires do when their shit starts to stink to everyone....They go into hiding or became instantly more sophisticated then provided a suitable distraction with money and television bullshitting.

Hardly much more sophisticated, the fucking president a year later used his own intelligence resources to break-into the Watergate hotel-A lot of sleepy motherfuckers on this sight should wake the fuck up and stop smelling their own farts long enough to realize that the 'left' and 'right' are the same fucking illusion.

Humans are easily-programmable units and universities are a perfect place to begin a new era of bullshit.

The program has never changed, and these fucks hold all cards except the mind and soul cards.

Insane Brawl During Red Sox Parade

marx was right-capitalism vs socialism

alcom says...

Capitalism is nearing the end of its useful life. Indeed, it has improved the lot for billions world wide but the wealth gap trend is concentrating power and money into a tiny and untouchable group if power elitists. I don't think we're heading for a USSR/China model of communism, but based on this repeating cycle of boom and bust where the oligarchy always comes out well ahead and the vast majority are left to suffer.

I heard throughout the talk that "Capitalism is stagnant," and "the problem is productivity." These points really ignore that those at the top of the heap actually profited during the financial crisis. I don't think this is simply a complaint about "fairness." I think this is the central issue.

Those with real wealth can leverage it to not only stay wealthy, but grow that wealth continuously. Since money begets influence, no significant change will take place until some major upheaval forces the masses into action. If Capitalism can keep adding bandage "corrections" after every recession, the status quo will probably continue.

Where Do Deleted Files Go?

lucky760 says...

Haven't watched the video yet, but I'll save you some time if you have no idea what the answer is: Deleted files don't go anywhere. Basically, the pointer to the file on the hard drive is just marked as deleted, but the data stays where it was before deletion.

This is why (on Windows) you can easily undelete from the recycle bin.

Your deleted files can be recoverable for a very long time because the data will sit there until some other data is saved in the same location. And even in that case, most of the original data might still go untouched for a long time.

This is how forensic computer geeks are able to recover all the dirty secrets you thought were really deleted.

To really delete something, the entire file's saved data needs to be overwritten. There's a lot of great software like Eraser that you can use to do this easily.

Wealth Inequality in America

Xaielao says...

I don't expect this to be fixed by politicians because they only benefit from such a system. Unfortunately one of the side-effects of having people with so much wealth and power that they are untouchable. They are above the law, above the court system and will never pay for the laws they have broken to gain their wealth and we have a political system in this country and around the world that will only help them do it. One would have thought that our politicians would have woken up after the 'Great Recession' but that clearly isn't the case. I only fear that the next great collapse will do even more harm as these people go unchecked in their greed and willingness to fuck over the middle class to make a buck.
