Indonesian Cave Art May Be World's Oldest

jmichaelg Art? (77 comments)

These new images look more like what kids would make when they first discover what happens if you toss pigment on your hand. Not a lot of art going on but it's fun.

The cave paintings in France are definitely art and were created around the same time.

Glut of Postdoc Researchers Stirs Quiet Crisis In Science

jmichaelg Reminiscent of Britain's brain drain in the 50's (283 comments)

Same thing happened in the 50's and 60's to Britain. Loads of smart people came here because there were so many jobs here and not at home.

  Now the jobs are in China and the available positions are over there, not here.

We don't have to break the treaty. We can withdraw from the treaty instead. From the treaty

Article XVI
  Any State Party to the Treaty may give notice of its withdrawal from the
Treaty one year after its entry into force by written notification to the Depositary
Governments. Such withdrawal shall take effect one year from the date of receipt of
this notification.

Getting Into College the Old Fashioned Way: With Money

jmichaelg Re:Not worth it (161 comments)

Having a degree from a state school hasn't hurt me as I am close to making upper management wages at a prestigious McCompany.

Had you gone to MIT or Stanford, you would have been surrounded by students who wanted nothing to do with being a wage slave but were looking to start the next fortune 500 company when they graduated. The lessons learned at college depend on the aspirations and talents of the student body.

FarmBot: an Open Source Automated Farming Machine

jmichaelg laser levelling (133 comments)

The fields I drive by on my way to work put the lie to the author's premise. A week ago, I saw a road-scrapper type device running around a field that had a spinning laser positioned more or less in the center of the field. The laser provided a level reference that the scrapper responded to moment by moment by lifting or lowering the blade. The machines are designed to build a field with a precise gradient so the farmer can minimize the amount of water needed to irrigate the field as well as to uniformly irrigate the crop. The water may be free but lifting it from the aquifer isn't.

Further down the road, there was a device that was building perfect raised beds covered in plastic. Strawberries need to be grown in well drained soil and the raised beds provide that. The plastic is used to keep a fumigant on the bed until it decays instead of leaking into the atmosphere prior to seeding. Once the soil is fumigated, it's planted by an automated planter that leaves the plastic in place to reduce evaporation - again to save water.

The next field over was being harvested by a machine that requires two people to operate it. Ten years ago, there'd be a crew of 30 doing the same task.

The industrial revolution upended farming from what it was centuries ago and that process hasn't stopped since. The net result is fewer people are needed to grow more food at a lower cost. Downside is calories have become so cheap that most of us are overfed.

The First Person Ever To Die In a Tesla Is a Guy Who Stole One

jmichaelg Stole a Tesla? How? (443 comments)

I thought Teslas had a literally encrypted key that all but guaranteed the car couldn't be stolen sans key.,

Did the service center leave the key with the car or is the car inherently insecure?

Interviews: Ask Former Director of JPL Edward Stone About Space Exploration

jmichaelg Early Education (58 comments)

In the early days of the space and aerospace programs it seems a lot of team leaders were engineers who had no college or stopped at a bachelors. Kelly Johnson at the Skunk Works is an example of the later.

When you started out, did you work for any men who didn't have a lot of formal education but were very competent?

Born To RUN: Dartmouth Throwing BASIC a 50th B-Day Party

jmichaelg Re:The original Basic Book (146 comments)

The deal with Basic was it was everywhere. Any computer you had access to had Basic readily available from the command prompt.

Now , it's Javascript. Available on most computers and runs on most computers.

Daylight Saving Time Linked To Heart Attacks

jmichaelg Be skeptical (240 comments)

Went looking for the original paper to see how many cases were looked at. Dr. Sandhu doesn't show up in a search for UC at Denver so no luck there. A few news article referenced a Conference which points to http://www.medpagetoday.com/Me... .

That page says that the # of extra attacks is 8. Moreover, Dr. Sandhu is quoted as saying that the total number of heart attacks in the week leading up to and following the clock change is unchanged so if there is an effect at all, it's front-loading the week's expected heart attack frequency.

Engine Data Reveals That Flight 370 Flew On For Hours After It "Disappeared"

jmichaelg Re:The real puzzle (382 comments)

The obvious implication is they were hijacked. The not so obvious explanation is hypoxia-induced dementia in the pilots.

I've yet to see anything that eliminates either possibility.

It's True: Some People Just Don't Like Music

jmichaelg Count Feynman as one who disliked music (268 comments)

Richard Feynman said music sounded like noise to him. Didn't make any difference what type of music it was. He did however, like rhythm which is why he played percussion instruments.

Is Google Making the Digital Divide Worse?

jmichaelg Re:If only there were a system (259 comments)

...complete with regulators that would end up working for the companies they regulate.

And of course, said regulators would raise the price of entry so that the incumbents would have a natural advantage.

What a novel idea!

Global-Warming Skepticism Hits 6-Year High

jmichaelg Both sides are spending lots of money... (846 comments)

Indian Chief paid $55,000 to attend anti-oil rally.

Synopsis: The Tides Foundation paid $55,000 to a Ltd Corporation that has is owned by another corporation that has changed its name twice in the past four years. The Indian chief is a director of the holding corporation. Tides made 25 different payments to anti-oil sands activists in a single year.

There's nothing wrong with paying money to support a cause you believe in but it's damn fishy when the money is flowing through corporations that are held by other corporations which keep changing their names. It indicates an attempt to hide who is actually receiving the money and how much money is flowing to said individuals.

The Saudis and Russians have a vested interest in stopping oil development in North America so it wouldn't be at all surprising to see them funding anti-oil activists.

Supreme Court Refuses To Hear Newegg Patent Case

jmichaelg Why software patents exist at all (204 comments)

Back in the day, software was not patentable as it was treated akin to a mathematical formula. The one patent I was aware of was a patent Atari snuck through by designing a circuit that XOR'ed a bit pattern to change the color a TV was displaying to avoid burn in. They patented the circuit and tucked a sentence into the patent that said they also claimed any implementation in software as well but the primary patent was for the circuit. We relied on copyright protection and pretty much ignored patents. Then the Supreme Court made a few rulings that opened the door to the possibility of patenting software.

Following up on the rulings, the Patent Office embarked on a series of "hearings" held around the country ostensibly to see whether it was a good idea to patent software or not. This was sometime in the early 90's. Towards the end of their tour, they finally brought their dog and pony show to San Jose.

Literally, almost *EVERY* developer testified that it was a really bad idea. The one exception that I recall was some idiot with a beauty salon app that would show you what you would look like with various hair styles. The rest of the developers said "No. We don't want this - it's a really, really, bad idea." Several developers made the point that we weren't constrained by a paucity of ideas as much as choosing which ideas to implement well.

The other group that was there in some numbers were attorneys - I recall Borland sent their corporate attorney. To a man, the attorneys all testified in favor of the idea.

Towards the end of the testimony, one of the developers pointed out the fact that the only people who seemed to like the idea were the attorneys. At which point, the Patent Office person (can't remember his name but iirc he headed the department at the time.) grinned and said something to the effect that the attorneys tended to get their way.

And they did. The people whom patents ostensibly protected were ignored in favor of the attorneys.

Army Laser Passes Drone-Killing Test

jmichaelg Re:Reflective Armor (173 comments)

How well a reflective surface would work would depend on the laser's power and frequency. Mylar doesn't reflect all frequencies of light and is imperfect at reflecting the ones it does. Pour enough joules onto the target and you don't care that 90% of them are being deflected - the remaining 10% will do the job.

I've always thought that the ideal anti-mortar device would be a radar that told you exactly where the mortar round came from. "You shooting at us? Here, have a little present in return."

Scientists Says Jellyfish Are Taking Over the Oceans

jmichaelg Plankton die off (274 comments)

Restore the plankton and you've restored the bottom of the food chain.

The plankton have died off by at least 40% over the past 60 years. John Martin at the Monterey Bay Aquarium Research Institute hypothesized in the early 90's that the die-off was due to diminishing iron in the ocean surface waters. He was quoted as saying "Give me a freighter full of iron fertilizer and I'll give you an ice age." meaning that spraying iron onto the ocean's surface would re-populate the plankton and they in turn would consume the excess CO2 that's currently acidifying the oceans.

In 2002, MBARI validated his hypothesis that spraying iron fertilizer would engender a plankton bloom. Subsequent studies have replicated MBARI's results.

Seems to me that if someone were to claim a 100 square mile chunk of ocean, they could fertilize it, seed it with anchovies and start a very profitable aqua farm. They would be harvesting a variety of predator fish such as bass and tuna once they discovered the anchovies feasting on the plankton. Since the farm wouldn't harvest all of the carbon the plankton consumed, it'd be a net carbon sink.

Send The ISS To The Moon

jmichaelg jmichaelg writes  |  more than 6 years ago

jmichaelg (148257) writes "Michael Benson is suggesting that NASA send the International Space Station to the moon instead of leaving it low earth orbit. He points out that it's already designed to be periodically moved to higher orbits so instead of just boosting it a few miles, strap on some ion engines and put it in orbit around the moon instead of the earth. That would provide an initial base for the astronauts going to the moon and give the ISS a purpose other than studying the effect of micro gravity on humans."

An application for Berkeley's Nanotube radio

jmichaelg jmichaelg writes  |  more than 6 years ago

jmichaelg (148257) writes "Hot on the heels of yesterday's article about Berkeley's nanotube radio receiver comes this Los Angeles Times article about John Kanzius, a former radio technician who was diagnosed with cancer. Kanzius, who has no medical background, applied his radio skills to his cancer with the intent of baking the cancer. Between chemotherapy treatments, he built a radio transmitter in his garage. To find the ideal radio receiver, he teamed up with Richard Smalley , the 1996 Chemistry Nobel Prize winner, who was also being treated for cancer. Smalley gave him two vials of nanoparticles which, when heated by Kanzius' radio transmitter, destroyed 100% of cancerous cells in a petri dish. The task now is to design a delivery mechanism based on antibodies that'll transport the particles an in-vivo cancer. Kanzius is listed as a co-author on a peer-reviewed paper to be published in the December issue of Cancer."
