Clean Energy Alone Does Not Equal Climate Action

Photo: Flickr, ca2hill , CC When I wrote my reactions to Obama’s State of the Union address last week, I mentioned how disappointing it was that he didn’t take the chance to engage the American public on the issue of climate change. The most common retort to this was along the lines of well, actions speak louder than words — and calling for a vast mobilization of clean energy is practically the same thing. Well, no it ain’t.

Hackers increasingly using telnet for attacks, port 23 looking younger than ever

You can’t always just hang around waiting for the next big Microsoft security update . Sometimes you have to go and make your own destiny — even if it means probing a few dusty ports. That’s apparently the mantra of modern hackers who are, according to Akamai, increasingly looking back at telnet as a means to gain unapproved access to systems of all shapes and sizes. Admins of course should be relying on SSH for such remote shell access, far more secure, but apparently many like to keep port 23 open for old time’s sake. Green-screen nostalgia is, apparently, a dangerous thing.

Not only are the feds picking on how many Twinkies vs. how many carrots you eat, but the New York Times reports that now they’re picking on how much you eat, period. The newest federal nutrition guidelines, revised every five years, predictably admonish Americans to eat more fruits and vegetables…

Gas Companies Illegally Using Diesel Fuel for Fracking

Fracking, or Fracing as the oil and gas industry ungrammatically spells it, is short for hydraulic fracturing , and the technology is now being used extensively to extract shale gas, by pumping liquids at high pressure into the rock, creating and expanding fissures. The liquid is a mix of chemicals designed to carry a proppant , perhaps sand or ceramics, designed to keep the cracks open after the injection stops. Controversially, it is exempt from the Safe Drinking Water Act, unless diesel fuel is used. (we noted that diesel was used in our first post on the subject: Ja… Read the full story on TreeHugger

Hokies give (tactile) sight to the blind so they can drive, no word on turning water into wine

Daytona International Speedway is synonymous with speed, auto racing, and . . . blind people? Virginia Tech’s Robotics and Mechanisms Laboratory (RoMeLa) , along with the National Federation of the Blind (NFB), recently debuted its sight-optional and street-legal SUV at the famed racetrack. Dr. Dennis Hong and his students first let blind folks drive a dune buggy without the help of a sighted copilot in 2009 — as a first step to achieving the goal of a street-legal SUV for the sightless crowd . The SUV in question was designed for the NFB’s Blind Driver Challenge, and is equipped with a drive-by-wire system — also seen in the RoMeLa autonomous vehicle — that was modified for use with RoMeLa’s SpeedStrip and DriveGrip tactile interface technology. It works by using a laser rangefinder to map the surrounding area, relaying information for acceleration and braking to the driver by rumbling the SpeedStrip seat, and passing along turning info through vibrations in the DriveGrip gloves. The system was not developed solely for the purpose of getting blind drivers on the road, however, as Virginia Tech suggests that its technology could also be used in gaming applications. We’re not quite ready to see blind drivers on actual roads just yet, but why shouldn’t our sight-impaired friends get to enjoy Gran Turismo 5 with the rest of us? Video’s after the break.

Yet another stick in the spoke s of the geopolitical world wheel! And of course, climate change has nothing to do with the extreme weather affecting crops around the world — and neither does the fact that Wall Street hedge funds have allegedly been locking up the commodities marke t, driving up the costs of food. That’s because we live in America, where reporters never ask rude questions! U.S. grain prices should stay unrelentingly high this year, according to a Reuters poll, the latest sign that the era of cheap food has come to an end. U.S. corn, soybeans and wheat prices — which surged by as much has 50 percent last year and hit their highest levels since mid-2008 — will dip by at most 5 percent by the end of 2011, according to the poll of 16 analysts. The forecasts suggest no quick relief for nations bedeviled by record high food costs that have stoked civil unrest. It means any extreme weather event in a grains-producing part of the world could send prices soaring further. “Even if we have a good year, we are not going to have the inventories we’ve seen before. I really do think the time of cheap food prices is over, and that’s just it,” said analyst Chris Mann of Traders Group Inc in Chicago. “Everything is set to the point where supply equals demand right now. But if you pull one thing out of it, or if you disrupt the equation in some little way or tweak it, I think, with inventories as tight as they are, it will really have an impact on prices. A drought, a flood, anything,” said Mann. You’ll notice he doesn’t mention a thing about hedge funds pouring massive amounts of money into the commodities market after the housing market collapsed, and instead driving up food prices — which in turn, promote global economic and political unrest: When this process of “hedging” was tightly regulated, it worked well enough. The price of real food on the real world market was still set by the real forces of supply and demand. But all that changed in the mid-1990s. Then, following heavy lobbying by banks, hedge funds and free market politicians in the US and Britain, the regulations on commodity markets were steadily abolished. Contracts to buy and sell foods were turned into “derivatives” that could be bought and sold among traders who had nothing to do with agriculture. In effect a new, unreal market in “food speculation” was born. Cocoa, fruit juices, sugar, staples, meat and coffee are all now global commodities, along with oil, gold and metals. Then in 2006 came the US sub-prime disaster and banks and traders stampeded to move billions of dollars in pension funds and equities into safe commodities, and especially foods. “We first became aware of this [food speculation] in 2006. It didn’t seem like a big factor then. But in 2007/8 it really spiked up,” said Mike Masters, fund manager at Masters Capital Management, who testified to the US Senate in 2008 that speculation was driving up global food prices . “When you looked at the flows there was strong evidence. I know a lot of traders and they confirmed what was happening. Most of the business is now speculation – I would say 70-80%.” Masters says the markets are now heavily distorted by investment banks: “Let’s say news comes about bad crops and rain somewhere. Normally the price would rise about $1 [a bushel]. [But] when you have a 70-80% speculative market it goes up $2-3 to account for the extra costs. It adds to the volatility. It will end badly as all Wall Street fads do. It’s going to blow up.” The speculative food market is truly vast, agrees Hilda Ochoa-Brillembourg, president of the Strategic Investment Group in New York. She estimates speculative demand for commodity futures has increased since 2008 by 40-80% in agricultural futures .
