Abi Si (3765067) writes "This Udemy course is for all those who have heard a lot about 3d printing, but often wondered on how can they without any earlier experience of working on 3d modeling software's, can really take these tools in their own hands to 3D model & print their designs.

You will learn modeling for 3d printing from scratch to finish, this in not any other 3d modeling course which will just give you an idea about how 3d modeling is done. And then leave you midway without actually demonstrating on how to prepare a 3d model for 3d printing

Preparing a 3D model for 3D printing has many basic prerequisites like

Setting the model to real world dimensions in mm, inches, cm or ft
Making sure the model is water tight, providing wall thickness, removing of non manifold faces, overlapping faces , etc.
Exporting the model in a file format which is accepted by 3d printers
You will learn all these steps, in addition this course will also show you how to print and sell your models in 3d printing market places like shapeways, thingiverse, sculpteo, and make them a source of cash flow, requiring your minimum attention & time once you are done with uploading your models.

You have to use Coupon code LM3DPMM to unlock this course for $5($21 original price)"

Dying Lawn? It May Be Chinch Bugs

gulfstreambugs (3659303) writes | 24 minutes ago

gulfstreambugs (3659303) writes "Chinch bugs are a pest here in Florida. They like the warm sun and they love the grass. In fact, they love to eat the juice of the tender shoots of the grass which leaves them satisfied and you with a dying lawn. Chinch bugs are small insects that use their mouthparts to suck out the liquids from grasses. Their ability to do this depletes the grass of vital nutrients that it needs in order to sustain life. When there are too many chinch bugs feeding off the grass eventually it can mean dead patches of grass."

AfBoy (3764969) writes "This analysis is of tech job ads in the US, Australia, and Great Britain. VBA devs are paid on par with C# developers, although demand for their skills is much lower.

A graph of salary vs demand shows three groupings of languages, although not all skills are listed here (graph becomes too difficult to read otherwise). Some popular languages bot shown on the chart are C and C++ which also fall in the "established leaders" cluster and are not far off C# and Java."

Will Your Next Car Be Covered In Morphing Dimples?

cartechboy (2660665) writes | 8 hours ago

cartechboy (2660665) writes "Golfing and cars, not much in common there. But that's about to change thanks to a new technology from a research lab at MIT called Smorphs. The idea is simple: put a set of dynamic dimples on the exterior of a car to improve its surface aerodynamics and make it slipperier, and therefore faster. Pedro Reis is the mechanical engineering and research spearheading this project. A while ago Mythbusters proved the validity of the dimpled car form in a much more low-tech way. The concept uses a hollow core surrounded by a thick, deformable layer, and a smoother outer skin. When vacuum is applied, the outer layers suck in to form the dimples. The technology is only in its very earliest stages, but we could see this applied to future vehicles in an effort to make them faster and more fuel efficient."

The Earth barely missed solar storm equal to the Carrington event

eclectro (227083) writes "NASA is reporting that in July 2012 that a huge solar storm crossed the path that the Earth takes, with Earth missing it by a week. If the storm had occurred a week earlier it would have at least equaled the 1859 Carrington event. It would have sent civilization back to the 18th century costing the world economy 2 Trillion dollars. A scientist has calculated that the odds of this happening in the next ten years is 12%."

Long-range electric car world speed record broken by Australian students

is_this_gdog (3764791) writes "Sunswift solar car team from UNSW Australia has broken* an international world speed record for the fastest long-range electric vehicle, averaging a speed of 107km/h (66mph) over 500km (310miles) from a single charge with their car, eVe. Solar panels were not used for this record (with solar, the car has a range of over 500 miles), the challenge was endurance speed with battery only. There are faster electric cars, and one or two with longer range if you go slow enough — Sunswift eVe is the first to officially do 500kms at highway speeds.

One trillion Bq released by nuclear debris removal at Fukushima so far

AmiMoJo (196126) writes | yesterday

AmiMoJo (196126) writes "The operator of the damaged Fukushima Daiichi nuclear plant says more than one trillion becquerels of radioactive substances were released as a result of debris removal work at one of the plant's reactors. Radioactive cesium was detected at levels exceeding the government limit in rice harvested last year in Minami Soma, some 20 kilometers from Fukushima Daiichi. TEPCO presented the Nuclear Regulation Authority with an estimate that the removal work discharged 280 billion becquerels per hour of radioactive substances, or a total of 1.1 trillion becquerels. The plant is believed to be still releasing an average of 10 million becquerels per hour of radioactive material."

US passport processing delayed worldwide by defective software

Anomalyst (742352) writes "US passport and visa processing has failed officials reported Wednesday. Travellers have been stranded, over 50K in one country which officials decline to identify they also decline to idenify the issues being encountered "by policy". The database vendor was not identified, nor was the contractor for the database maintenance, (I suspect Oracle in both cases given the magnitude of the failure)"

Is our Universe left-handed?

StartsWithABang (3485481) writes "We generally think of the laws of physics as symmetric: there's no preferred location or direction in the Universe that's more physically valid than any other. And yet, there are some fundamental asymmetries: matter dominates over antimatter, muons decay in one direction and not the other 99.9% of the time, and left-handed spiral galaxies are more common than right-handed one. What, didn't know that last one? Turns out that's a real effect, and it's been noticed in more than one study. But is the fault in the stars, or is it ours?"

Lawrence Krauss: Congress is trying to defund scientists at Energy Department

Lasrick (2629253) writes "Physicist Lawrence Krauss blasts Congress for their passage of the 2015 Energy and Water Appropriations bill that cut funding for renewable energy, sustainable transportation, and energy efficiency, and even worse, had amendments that targeted scientists at the Department of Energy: He writes that this action from the US Congress is worse even than the Australian government's move to cancel their carbon tax, because the action of Congress is far more insidious: 'Each (amendment) would, in its own way, specifically prohibit scientists at the Energy Department from doing precisely what Congress should mandate them to do—namely perform the best possible scientific research to illuminate, for policymakers, the likelihood and possible consequences of climate change' Although the bill isn't likely to become law, Krauss is fed up with Congress burying its head in the sand: The fact that those amendments '...could pass a house of Congress, should concern everyone interested in the appropriate support of scientific research as a basis for sound public policy.'

"Magic Helmet" for F-35 ready for delivery

Graculus (3653645) writes | 10 hours ago

Graculus (3653645) writes "This week, Lockheed Martin officially took delivery of a key part of the F-35 fighter’s combat functionality—the pilot’s helmet. The most expensive and complicated piece of headgear ever constructed, the F-35 Gen III Helmet Mounted Display System (HMDS) is one of the multipurpose fighter’s most critical systems, and it's essential to delivering a fully combat-ready version of the fighter to the Marine Corps, the Navy, and the Air Force. But it almost didn’t make the cut because of software problems and side effects akin to those affecting 3D virtual reality headsets.

Built by Rockwell Collins ESA Vision Systems International (a joint venture between Rockwell Collins and the Israeli defense company Elbit Systems), the HMDS goes way beyond previous augmented reality displays embedded in pilots’ helmets. In addition to providing the navigational and targeting information typically shown in a combat aircraft’s heads-up display, the HMDS also includes aspects of virtual reality, allowing a pilot to look through the plane. Using a collection of six high-definition video and infrared cameras on the fighter’s exterior called the Distributed Aperture System (DAS), the display extends vision a full 360 degrees around the aircraft from within the cockpit. The helmet is also equipped with night vision capabilities via an infrared sensor that projects imagery inside the facemask"

Western U.S. states using up ground water at an alarming rate

sciencehabit (1205606) writes "A new study shows that ground water in the Colorado basin is being depleted six times faster than surface water. The groundwater losses, which take thousands of years to be recharged naturally, point to the unsustainability of exploding population centers and water-intensive agriculture in the basin, which includes most of Arizona and parts of Colorado, California, Nevada, Utah, New Mexico, and Wyoming. Because ground water feeds many of the streams and rivers in the area, more of them will run dry."

Chromebooks are outselling iPads in Schools

Nate the greatest (2261802) writes "Apple thrilled investors earlier this week when they revealed that they had sold 13 million iPads to schools and claimed 85% of the educational tablet market, but that wasn't the whole story. It turns out that Apple has only sold 5 million iPads to schools since February 2013, or an average of less than a million tablets a quarter over 6 quarters. It turns out that instead of buying iPads, schools are buying Chromebooks. Google reported that a million Chromebooks were sold to schools last quarter, well over half of the 1.8 million units sold in the second quarter. With Android tablets getting better, Apple is losing market share in the consumer tablet market, and now it looks Apple is also losing the educational market to Google. Analysts are predicting that 5 million Chromebooks will be sold by the end of the year; how many of those will be sold to schools, do you think?"

U.S. reveals secret plans for '60s moon base

mpicpp (3454017) writes | 11 hours ago

mpicpp (3454017) writes "The U.S. military races to the moon to build a base — to beat the Russians to the punch. Maybe test a nuclear weapon on the surface. Consider a lunar-based bombing system to target earthbound foes.

That was the plan in the 1960s, according to declassified national security documents released this week — some of them stamped as "SECRET."
Today those schemes may sound as outlandish and dusty as a relic black-and-white episode of "Space Patrol."

The U.S. Army brainchild "Project Horizon" was born.
Its proposal to leap beyond the Soviets opened with the line: "There is a requirement for a manned military outpost on the moon."

The paper argued that it was imperative for the United States to develop and protect its potential interest on the Earth's natural satellite — and to do so quickly to protect the American way of life.

"To be second to the Soviet Union in establishing an outpost on the moon would be disastrous to our nation's prestige and in turn to our democratic philosophy," the paper surmised.

It should have the kind of priority and authority given to the Manhattan Project, which developed the atomic bomb, the Army said.
"Once established, the lunar base will be operated under the control of a unified space command." The space around the Earth and moon would be considered a military theater."
