top Getting Into College the Old Fashioned Way: With Money
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.
top FarmBot: an Open Source Automated Farming Machine
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.

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.

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
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.

top Global-Warming Skepticism Hits 6-Year High
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.
top Supreme Court Refuses To Hear Newegg Patent Case
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.
top Army Laser Passes Drone-Killing Test
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."
top Scientists Says Jellyfish Are Taking Over the Oceans
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.
