Multicast is not a viable technology for truly large scale deployments (more than a few hundred thousand hosts perhaps). Routers and switches do not have the required resources to maintain multicast routing/switching tables for millions of multicast sessions.

The correct way to solve the problem is to push it to the end nodes. They have much more CPU power and memory than routers and switches. The technology to do so has existed for a long time: P2P.

Thats how the internet is paid for. The sending provider pays the receiving provider for the bandwidth, and this is the only rational way it can be.

No. That is not how it works. The truth is that the smaller provider pays the larger provider, no matter which direction the traffic flows. Some companies, like Netflix, are nice enough to not use their size as an excuse to charge people -- they offer free peering at internet exchanges. Other companies are maximally greedy.


Russia Posts $110,000 Bounty For Cracking Tor's Privacy 90

The public description (in Russian) of the project has been removed now and it only reads "cipher 'TOR' (Navy)." The ministry said it is looking for experts and researchers to "study the possibility of obtaining technical information about users and users' equipment on the Tor anonymous network."

Earth In the Midst of Sixth Mass Extinction: the 'Anthropocene Defaunation' 265

Posted by Soulskill
from the i-blame-the-schools dept.
mspohr writes: A special issue of Science magazine devoted to 'Vanishing Fauna' publishes a series of articles about the man-caused extinction of species and the implications for ecosystems and the climate. Quoting: "During the Pleistocene epoch, only tens of thousands of years ago, our planet supported large, spectacular animals. Mammoths, terror birds, giant tortoises, and saber-toothed cats, as well as many less familiar species such as giant ground sloths (some of which reached 7 meters in height) and glyptodonts (which resembled car-sized armadillos), roamed freely. Since then, however, the number and diversity of animal species on Earth have consistently and steadily declined. Today we are left with a relatively depauperate fauna, and we continue to lose animal species to extinction rapidly. Although some debate persists, most of the evidence suggests that humans were responsible for extinction of this Pleistocene fauna, and we continue to drive animal extinctions today through the destruction of wild lands, consumption of animals as a resource or a luxury, and persecution of species we see as threats or competitors." Unfortunately, most of the detail is behind a paywall, but the summary should be enough to get the point across.

Will Your Next Car Be Covered In Morphing Dimples? 134

cartechboy 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.

Your link says:

218 Republicans voted for, 159 Democrats voted against.

So a few Democrats and Republicans breaking ranks does not make this bipartisan. Clearly this is a deeply partisan issue.

You also forget to mention that not one single bill can be voted on unless the Speaker of the House, Republican John Boehner, says it can be voted on.

So, how is this bipartisan again? It was a Republican bill, passed with a Republican majority. Welcome to politics.


One Trillion Bq Released By Nuclear Debris Removal At Fukushima So Far 178

Posted by samzenpus
from the spreading-the-glow dept.
AmiMoJo 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.

+ - Is our Universe left-handed?

Submitted by StartsWithABang
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 270

Posted by samzenpus
from the let-the-science-flow dept.
Lasrick 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."

Would you people stop playing these stupid games?!?!?!!!!
