How Heroin Addicts Helped Scientists Link Pesticides and Parkinson's

DeathGrippe Demerol, not heroin. (109 comments)

MPP is a byproduct of sloppy meperidine synthesis, NOT heroin. Meperidine is "Demerol."

Scientists Invent Urine-Powered Robots

DeathGrippe Not a very BFD (123 comments)

This appears to be the original article:

Here's the abstract:
"The first urine-activated laminated paper batteries have been demonstrated and reported in this paper. A simple and cheap fabrication process for the paper batteries has been developed which is compatible with the existing plastic laminating technologies or plastic molding technologies. In this battery, a magnesium (Mg) layer and copper chloride (CuCl) in the filter paper are used as the anode and the cathode, respectively. A stack consisting of a Mg layer, CuCl-doped filter paper and a copper (Cu) layer sandwiched between two plastic layers is laminated into the paper batteries by passing through the heating roller at 120 C. The paper battery is tested and it can deliver a power greater than 1.5 mW. In addition, these urine-activated laminated paper batteries could be integrated with bioMEMS devices such as home-based health test kits providing a power source for the electronic circuit."

Looks to me like it's nothing more than the old trick of making a battery out of a lemon or other piece of acidic fruit.

The Neuroscience of Happiness

DeathGrippe Positive vs negative reinforcement (136 comments)

Animal trainers have demonstrated repeatedly that positive reinforcement is more effective at eliciting behavior than negative. In other words, the carrot works better than the stick.

To me, this seems contradictory.

Study Ties High Blood Sugar To Dementia

DeathGrippe Brain diabetes (157 comments)

This is particularly interesting because alzheimer's is now thought, by many researchers, to be a form of "brain diabetes."

There are clinical data which demonstrate that alzheimer's can be reversed to some extent with medium chain triglycerides, which are absorbed by cells directly and provide energy which isn't dependent on glucose uptake.

After Lavabit Shut-Down, Dotcom's Mega Promises Secure Mail

DeathGrippe Eliminate mail servers (158 comments)

The problem is that email is managed from a central location.

If email clients opereated as fully encrypted standalone, "peer to peer" entities, the central mail server would be eliminated, and snoops would only be able to grab the encrypted content, and perhaps the locations of sender and receiver.

You don't know that for a fact. Russian intelligence is every bit as invasive as ours, and is subject to far fewer restrictions. Putin himself recently said that the US is only doing what the Russians have been doing all along. And, don't forget, Putin is the former head of the KGB.

Math and Science Popular With Students Until They Realize They're Hard

DeathGrippe You need to teach incredible persistence (580 comments)

""If more science graduates are desired, the findings suggest the importance of policies at younger ages that lead students to enter college better prepared (PDF) to study science.""

Secondary and college students are subjected to only the most minimal of discouragement compared with what they will experience in the real world of academic and industrial science. Research progress is based on multiple failures, punctuated by brief, intense flashes of insight. There is a lot of chance involved, because there is a great deal of educated guesswork leading to theories and experiments.

High school, and college barely begin to prepare you for grad school and life in the real world.

Ask Slashdot: Getting Hired As a Self-Taught Old Guy?

DeathGrippe Headhunter's secrets (472 comments)

As a former headhunter, here is my best advice:

1. Avoid headhunters. All they'll do is attach a commission handicap toward hiring you.

2. Find out where there are places nearby where you'd like to work and are qualified.

3. Prepare a killer resume that describes your accomplishments in the terms of the job you could do for those employers.

4. Find out who the hiring managers are, and what positions, if any, are open.

5. Have three copies of your resume available. Walk in the front door cold, and tell the person at the front desk your name and who you are there to see about the job.

6. If the front desk person asks for a resume, give it to them.

Generally, this will get you in front of the hiring authority. While you're talking with that person, aside from telling them all about the great things you can do, ASK FOR THE JOB! "This sounds great! I can start on Monday, would that be too soon?" etc.

Good luck.

The Men Trying To Save Us From the Machines

DeathGrippe Re:Consider super intellligence (161 comments)

Ok, point taken.

However, now consider that virtually every desktop computer could be the equivalent of one neuron, but with vastly more memory storage and data processing capabilities, and that every computer is connected to every other computer via this internet thing.

Now suppose someone were to write a little program that would make these computers the actual equivalents of a conscious neural network, all connected together into one, gigantic sentient being, a super intelligent botnet.

The Men Trying To Save Us From the Machines

DeathGrippe Consider super intellligence (161 comments)

Nerve impulses travel along nerve fibers as pulses of membrane depolarization. Within our brains and bodies, this is adequate speed for thinking and control. However, relative to the speed of light, our nerve impulses are laughably slow.

The maximum speed of a nerve impulse is about 200 miles per hour.

The speed of light is over 3 million times that fast.

Now consider what will happen when we create a sentient, electronic being that has as many neurons as we do, but its nerve impulses travel at the speed of light.

In terms of intelligence, that creation will be to us as we are to worms.

Death of Trees Correlated With Human Cardiovascular & Respiratory Disease

DeathGrippe Re:Bad science (152 comments)

If and when AGW proponents start treating the issue seriously and try to solve it rather than make shitloads off of pecuniary schemes that would at best mitigate less than 10% of any harmful effects(assuming arguendo that their models are correct) while simultaneously greatly reducing quality of life, I will start to take them seriously. Since there's virtually no one demanding massive amounts of money be put into carbon sink research and major geoengineering projects, that time has not yet come.

Totally agree. Not only has that time not come, it will not come until multiple disasters wreak devastation to the extent that the world is forced to allocate the funds that would be required to mitigate the problems. The recent tornadoes are a taste of things to come. Unfortunately, given the way humans are, we will probably not come to that pass until it is too late.

Like the canary in the coal mine. When the bird drops dead, no one would claim that the dead bird caused the gas that killed it, and no fool would stay in there long enough to succumb.

Similarly, climate change deniers have a problem understanding that the messenger is not the problem, or the cause of it.

Sharing HBO Go Accounts Could Result In Prison

DeathGrippe Unenforceable laws (221 comments)

..generally carry much stiffer penalties to compensate for the difficulty of enforcement, and to more effectively discourage breaking them.

Unfortunately, this doesn't work well as it creates a new group of criminals who are then likely to commit other crimes. They also engender contempt of the legal system and the police, leading to increased cheating in other areas.

You could call these laws "gateways to crime."

What Keeps You On (or Off) Windows in 2013?

DeathGrippe Each has its uses, and they evolve (1215 comments)

Switched to linux some years back after getting fed up with BSA threats and MS paranoia, but kept one WinXP box for accounting, sitting in a lonely corner with no net connection. Added a couple Macs for marketing and admin functions. Then MS appeared to mostly get its act together, so a couple of Win7 boxes were added. I retired, and put a Win7 box on my desk for fun and games. So, current snapshot is linux for R&D operations and sales, Win7 for admin and goofing off, and WinXP (in isolation) for accounting.

Seeking Fifth Amendment Defenders

DeathGrippe Volume of text does not constitute proof (768 comments)

Interesting, and disturbing, that many people seem to believe that if they write voluminously about something, the case is proven.

I've always found that truth can usually be stated succinctly, while lies require plenty of smokescreen.

DeathGrippe Creating a problem where none exists (342 comments)

This kind of imposed "security" measure generally fails to provide any additional security, while at the same time treating children as criminals.

People treated as criminals, frequently respond by becoming so and thus provide continuing justification for the "security" measures that caused the problem in the first place.

Hackers Spawn Web Supercomputer on Way to Chess World Record

DeathGrippe DeathGrippe writes  |  about a year ago

DeathGrippe (2906227) writes ""By inserting a bit of JavaScript into a webpage, Pethiyagoda says, a site owner could distribute a problem amongst all the site’s visitors. Visitors’ computers or phones would be running calculations in the background while they read a page. With enough visitors, he says, a site could farm out enough small calculations to solve some difficult problems."

"With this year’s run on the value of Bitcoins — the popular digital currency — security expert Mikko Hyppönen thinks that criminals might soon start experimenting with this type of distributed computing too. He believes that crooks could infect websites with JavaScript code that would turn visitors into unsuspecting Bitcoin miners. As long as you’re visiting the website, you’re mining coins for someone else, says Hyppönen, the chief research officer with F-Secure."

The total surveillance society

DeathGrippe (2906227) writes "What if there was a simple app that would make your computer equivalent to a ganglion in an internet connected super mind which could see through every camera in every computing device in the entire world, as in "Person of Interest" and would combine the known lives and works of all humans, to the beginning of the historical record. It would not in any way interfere with your use of your computer, but would record every moment of your life, every move and every sound. There would be absolutely no privacy.

If it were offered, would you install it on your computer?

Would you be interested in building such an app?"
