Scientists Invent Urine-Powered Robots

moteyalpha Re:Not so very strange (123 comments)

There's a lot of useful chemistry and energy in ammonia (a significant component of urine), because nitrates, or bound nitrogen, have potential energy. Gunpowder manufacture in the middle ages relied on factory-style processing of animal urine.

Urine Connections
So the sewer bots will be powered by urine and manufacture explosives from the nitrates and will be equipped with sensors to smell each other. So the robot overlords will be under? So next we have the proof of concept hack of a sewer bot to create a distributed denial of existence (DDOE) attack.
Life is becoming a free science fiction movie. I smell a sequel with methane powered poop bots.

Germany Finances Major Push Into Home Battery Storage For Solar

moteyalpha Old is new again (282 comments)

Molten Batteries
I was surprised to learn that the concept behind molten batteries originated in Germany with the V1. MIT and Dr Sadoway have a battery system that is supposed to be available 2014. If it was invented in Germany and has since been used for ICBMs and ordinance. Seems odd that it has taken almost 70 years to come full circle.

Duke Univ. Device Converts Stray Wireless Energy Into Electricity For Charging

moteyalpha Re:Units! (216 comments)

7.3V of energy? USB provides 5V of power? Arggh. I think my head just asploded.

It's a chain reaction! Now my head asploded with 7.32 Volts of energy and 10 coulombs of mass.
They could be dealing in metric electrons.

EU Considering Sensors In Sewers To Detect Bomb-Makers

moteyalpha Re:And later (219 comments)

I realized this could be done decades ago. I am surprised that it has taken this long to be implemented. I work in robotics and recently in molecular genetics. It is a complete source of DNA for every person. It is a wealth of "raw" information and since analysis is getting cheaper every day it could become a new data base that can be collected and sold. It is creepy and that is why it creeps.
GATTACA. BTW, we checked your DNA and you have too many SNP's and will not be allowed to procreate as it would be a burden on the state. Also it would be the obvious creep of scope. Cold Cases with DNA and no match. It will happen.

EU Considering Sensors In Sewers To Detect Bomb-Makers

Dear Sir, We were monitoring the sewer and it seems your daughter is pregnant. We checked the DNA and it is that kid you don't like. We only know you don't like him because the NSA shares information with us. On the side are ads for abortion clinics, diaper services, gun shops, and obstetricians provided by WalMart. BTW you need to check your cholesterol.

New Technology For Converting a Metal To a Semiconductor With a Laser

moteyalpha Re:photoelectric effect (42 comments)

We've known about this since the turn of the last century. It's the photoelectric effect. Every material has a wavelength where if it is struck by a charged particle at or above that, it will absorb it and then emit an electron. This isn't news.

What's news is that we've now reached a sufficient level of understanding regarding the engineering of electro-optical systems that we are starting to build devices where the primary logic is based on optics, not electronics. This is an advancement of technology, not of understanding.

I am a bit confused by what you said. An incident photon at wavelength (Lamda) or smaller will eject an electron ( photo electric) and thermal excitation of a material like the cathode of a tube will also eject electrons. I am not getting where the charged particle comes in. From TFA:

In other situations, light can modify a material’s behavior — but only when it’s absorbed, transferring its energy to the material. In this experiment, Gedik says, the light’s energy is below the absorption threshold. This is exciting, he says, because it opens up the possibility of switching a material’s behavior back and forth without inducing other effects, such as heating — which would happen if the light were absorbed.

What they are talking about is changing the bandgap with the incident angle of polarized infrared laser light.

LinkedIn's New Mobile App Called 'a Dream For Attackers'

moteyalpha Re:Why is anyone surprised? (122 comments)

I'm not surprised ('social networks' in general make you the product, linkedin has always been a touch sleazy, especially for an ostensibly 'professional' site that could theoretically be making its money on the semi up-and-up by offering useful recruiting services);

Linkedin has many dubious methods that aren't visible to a typical person. I know some of the methods they employ to extend their grasp. The problem is that there is no way to explain this to people without a CS degree. It just irritates the victim to be a tool so they ignore it.
To go from ironic to sardonic as well as a self deprecating , we are providing social comments on a site owned by a company that handles employment (DICE). So it is posters on a 'social network' that complain of the use of themselves as product on a 'social network'.
But, that aside, I agree that this is right out of the ball park for sleaze and greed.

Silicon Supercapacitor Promises Built-in Energy Storage For Electronic Devices

moteyalpha Re:Meh (95 comments)

Super caps are neat for their application but suggesting they are useful for this is a stretch. It seems from RTFA that they think 5 Wh/Kg is comparable to 128 Wh/Kg for Li-ion . Also the incorporation into silicon presents serious issues that never get resolved in less than 10 years. No sane company is going to incorporate this in a line of CPUs and then find out that after a year they like to release their energy in one single burst. I suggest we test them in 747s first to make sure they are safe and do not pose any risk to my CPU.
Thanks for the link , looks interesting. Hands-on scientists like Science/Engineering/Tech forums

New Standard For Website Authentication Proposed: SQRL (Secure QR Login)

moteyalpha Re:Steve Gibson is a... (234 comments)

I invite everyone to let Google autocomplete that sentence. It's been well-known for a good while that absolutely no-one should pay any attention to him.

Just for giggles I did test auto complete on that and it gave:
1. steve gibson is a fake
2. steve gibson is a moron
3. steve gibson is a idiot
Could that be considered the -opinion- of the Google algorithm?
My opinion about TFS involves squirrels too. But mainly their primary food source ( pronounced 'nuts').

35,000 vBulletin Sites Have Already Been Exploited By Week Old Hole

moteyalpha Re:Why Only Now? (91 comments)

If you watch your server access logs, you will regularly see bots checking for common install URLs of popular website software. I'm blown away that vBulletin's hasn't been targeted for years.

You are absolutely right. I was shocked at how quickly the knocking began. Within a day of registering a new address it already had obvious attempts to find a hole. The logs also show many other things that would worry people IF they knew it was happening. Very few people have the experience and skills to deal with it. It seems obvious that the intruder has the advantage. In a system with more than 2 to the 64th directions to guard against, the attacker has the advantage of surprise.
Analogy: Open field, everybody has a gun, some have food, others want it.
It could be that the only way to win is not to play at all. The problem is that the game has already started and this is no longer a choice. There is a dominant strategy. It is a conflict of interests. It is thus "Bellum Omnium contra omnes". No way to tell how it will end, but everybod has a "shot". ;)

RMS: How Much Surveillance Can Democracy Withstand?

moteyalpha Re:that ship has sailed (264 comments)

The question may be whether the internet should die and be replaced by something better.

Simply implementing ipv6 isn't going to cut it for you?

I never minded having company meetings that included everybody. The internet is like a company meeting where people off the street are allowed to attend wearing a stocking on their head and screaming obscenities and nonsense and grabbing papers from the table, while everybody else is trying to accomplish something. Anything other than limited complexity is just toothpaste in a hole. Ten to the ninth factorial is a REALLY big number. It can never be operated by a competitive population. Maybe human V6 will all be able to be in the same room.
There was talk about getting the worst type of literature off the ebook sites, but in reality the internet is a toliet and they just have a problem with solid waste as it clogs the tubes.

RMS: How Much Surveillance Can Democracy Withstand?

moteyalpha Re:that ship has sailed (264 comments)

The question may be whether the internet should die and be replaced by something better. The cost of doing business through the internet may be too high compared to some other alternative. It has failed to exhibit a plan for -sustainable- profitability and it is too connected. It is like a brain tumor. It has no core structure that could serve to regulate growth or partition against assault. Designing security or subjective isolation after the fact is becoming an ever increasing burden that will only get worse. It might be a good network for a nuclear war, but it has served as an example of what not to do and now a new system needs to be designed that has no middle man to pay. ( In ad clicks, private information, overages, outages, loss of security, escalating prices, ...)
The signal to noise ratio is rising and will drown any utility eventually. CARRIER LOST

D-Link Router Backdoor Vulnerability Allows Full Access To Settings

moteyalpha Re:Will this stupidity ever end? (228 comments)

The problem that I have observed is that there is no effective oversight to complex systems. The people who can deal with the complexity and create things like this work in a sort of isolation. Sometimes this happens when contractors are asked to create a system and then get paid. If they don't get paid, they leave the back door. I can guarantee that this is not the last one that is found and some are much worse than this. I was looking at the javascript linked in an earlier article and it reminded me of the "never attribute to malice ...." . When you add the possibility that espionage or criminality could be involved it gets even more complicated. I help relatives with computer problems on a daily basis and most people have trouble just figuring out how to use the damn things. They are completely vulnerable to even the simplest tech attack or SE.
I also have my own site and I see many things. I know that every day there are people knocking on doors or ports. It is another world that most people only understand as some kind of stuff done by technically afflicted people.

UCSD Students Test Fire 3D-Printed Metal Rocket Engine

moteyalpha Re:So did it work? (55 comments)

It was an interesting article. I was hoping for something more detailed and technical as well as new. Printed guns got a lot of coverage and I thought that was just a way to get attention through controversy. A rocket that could be -completely- printed would be a far more effective weapon. What I did not appreciate was a gizmag popup that asked for my email to subscribe. I am capable of discovering what I want to read and when.

3D Printing a 'Terminator' Arm ... Or a Whole Body

moteyalpha Re:Slight problem (29 comments)

Oh yes yes, I imagine it will be a labor-free utopia after that. Where have I heard that before? Oh yeah, the leisure society! Instead, we now have a society where we're SURROUNDED by technology and resources, but somehow both people of a couple need to "work" now. What a paradise!

The problem with your argument is that you assume that I am doing it for you. "Wow really" is certainly a compelling argument but I have advanced technology that absolutely proves "Oh, yeah?". Complicated and impossible is nonsense. if [ N && !N ]. I hope you don't write shell scripts for somebody.

Google ToS Change Means Your Photo Could Go In Ads

moteyalpha Re:The big differences... (136 comments)

Vast amounts of personal information are already available on the internet. The focus is to monetize what is publicly available. The issue seems to be -who- gains from what is laying around in the open or what can be inferred. The present model seems to revolve about connecting products to sales and taking a cut. That does not seem to be a sustainable gain. It requires that the consumer be actively involved in the process and people can simply stop using the internet without dying. The internet has exposed almost every person to scrutiny. Information does not act by itself. It is the motives and real world actions of those who observe that information that matter.
I'm going to hang up this phone, and then I'm going to show these people what you don't want them to see.

3D Printing a 'Terminator' Arm ... Or a Whole Body

moteyalpha Re:Slight problem (29 comments)

The biggest advantage that could be achieved in 3D printing is the self replicating printer. That would seem to be the best focus for a first design.
There are many ways to achieve that goal and I have tested several methods that can be integrated in a single device. The challenges include working directly to metals, printed electronics, precision and speed. These are all attainable goals and it seems that the hype goes more to what can be done to monetize and control the industry of 3D printers.
There is no doubt that other things can be done when the proper framework is created. It seems that the technology is at that threshold similar to the first integrated circuits on a chip and a complete microprocessor. The real progress comes when the device can successfully duplicate itself. It would be the Cambrian explosion of the personal industrial revolution.
It presents many new problems for society as a whole because it short circuits the consumer pathway from manufacturing to sale. The actual cost of products drops radically when you cut out several layers of middle men. There is no doubt that it will eventually happen. There is also no doubt that the existing economic and political structure will vehemently oppose such a process.

Should slashdot diversify

moteyalpha moteyalpha writes  |  about 7 months ago

moteyalpha (1228680) writes "It seems to me that slashdot has failed to take advantage of its own resources to achieve something useful. As a profit company now it seems to have fallen into a model that would support Google, but is not appropriate for a smaller company. People wonder if Google complies with its policy of Do No Evil, but does Slashdot have any plans to do anything like Google X or just continue to exploit their user base with advertisements until they run them selves to ground? I suspect the Slashdot company policy is not "Do No Evil ", but, "Do Nothing". Do they do anything at all or is it just a program that allows users to select submissions and the work is done by moderators. Batteries not included."

Energy as money

moteyalpha moteyalpha writes  |  about 8 months ago

moteyalpha (1228680) writes "In the process of research into 3D printing I have modified an existing way to generate and store electrical potential energy cheaply and efficiently using some new sub micron 3D techniques. I have been following the progress of Dr Sadoway's liquid metal battery at MIT as well as his open course in physical chemistry and he is a great teacher and obviously creative as well. I have put together some information on my extension of the ideas relating to energy and money.. But since RTFA is not very common, I will paraphrase. It seems that electron potential could become currency that could literally power advancements in human achievement when combined with a completely self replicating 3D printer. The only other achievement that could rival it would be a fungus that was self replicating, could generate energy from sugar, and manufacture a chemical compound like alcohol. Maybe somebody will create that."

Sex and War

moteyalpha moteyalpha writes  |  more than 5 years ago

moteyalpha writes "How could you pick a more sexy or scary title than that? Wired reviews "SEX AND WAR" by Malcolm Potts and Thomas Hayden. I agree with the concept and they have many nice pictures there, for those, like myself, that want to be distracted a bit while they read. It is not hard to guess my position as it comes to the need of nations to stop the organized crime of war before it is ended by the extinction of all life.

It isn't because I am a peace and love kind of guy, I am not really that fond of most people. It is because it can be no other way and resolve. It is that same way with open source. I don't believe in it because of some philosophical bent, it is just the only way to be effective in a group. I ignore the fact that most of the people I respect, admire, and work in harmony with in the community would probably drive me crazy if I had to see them every day in real life.."
