I think it is good that someone comes up with an idea that seems so outrageous and so far fetched that it is really challenging to aim for.

We need another "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.

Some switches seem to have a multicast problem: we've downed very fancy cisco switches recently (can't recall the number right now) with igmp/multicast traffic.

We've had a couple of hundred embedded systems that were announcing themselves on the network with mdns. That in itself is only a very low amount of traffic.

Probably some management software triggered a slight increase in reporting, but with a couple hundred embedded systems, this was enough.

mc traffic/igmp does not seem to be hardware accelerated; being routed to the main switch CPU -> maxed out.

Disabling mdns 'solves' the problem.

Researchers Claim To Be Able To Determine Political Leaning By How Messy You Are 592

Posted by samzenpus from the dirty-liberal dept.
According to a study to be published in The Journal of Political Psychology, you can tell someone's political affiliation by looking at the condition of their offices and bedrooms. Conservatives tend to be neat and liberals love a mess. Researchers found that the bedrooms and offices of liberals tend to be colorful and full of books about travel, ethnicity, feminism and music, along with music CDs covering folk, classic and modern rock, as well as art supplies, movie tickets and travel memorabilia. Their conservative contemporaries, on the other hand, tend to surround themselves with calendars, postage stamps, laundry baskets, irons and sewing materials. Their bedrooms and offices are well lit and decorated with sports paraphernalia and flags — especially American ones. Sam Gosling, an associate professor of psychology at the University of Texas at Austin, says these room cues are "behavioral residue." The findings are just the latest in a series of recent attempts to unearth politics in personality, the brain and DNA. I, for one, support a woman's right to clean.

Your Identity Is Worth Less Than $15 178

Posted by kdawson from the less-than-your-fillings dept.
I Don't Believe in Imaginary Property writes "One of the more interesting tidbits in Symantec's Global Internet Threat Report (PDF, 105 pages) is the price sheet, which suggests that someone's 'full identity' is worth in the range of $1-$15. Your email password goes for $4-$30 and your bank account might fetch $10-$1000. With those prices, I wonder how often they pay more for the bank account than is actually in it? There's also an executive summary (PDF, 36 pages)."

Alligator Blood May Be Source of New Antibiotics 265

Posted by Zonk from the darn-tasty-eating-too dept.
esocid writes "Biochemists from McNeese State University have described how proteins in gator blood may provide a source of powerful new antibiotics to help fight infections associated with diabetic ulcers and severe burns. This new class of drug could also crack so-called 'superbugs' that are resistant to conventional medication. Previous studies have showed alligators have an unusually strong immune system; unlike humans, alligator immune systems can defend against microorganisms such as fungi, viruses, and bacteria without having prior exposure to them. Scientists believe that this is an evolutionary adaptation to promote quick wound healing, as alligators are often injured during fierce territorial battles."

Sony Thinks Blu-ray Will Sell Like DVDs by Year End 434

Posted by Zonk from the ambitious-planning dept.
An anonymous reader writes "Sony CEO Ryoji Chubachi knows something we don't. At a press conference, he announced Sony's plan to increase Blu-ray market share to 50% of all movie discs by the end of the year. 'DVD and BD currently account for about 80% and 20%, respectively, of global demand for movie discs, Chubachi indicated. The new BD devices to be offered by Sony include models integrating an HD LCD TV with BD recording functionality, Chubachi pointed out. Sony has relied mainly on the PlayStation 3 (PS3) to promote BD, and sales of the game console will increase along with the offering by top Hollywood studios of new BD movies, Chubachi noted. However, Sony will extend its BD promotion from the current focus on the PS3 and BD players/recorders to IT devices, Chubachi pointed out.'"

The Real Mother of All Bombs, 46 Years Ago 526

Posted by kdawson from the things-that-go-boom dept.
vaporland writes "Tsar Bomba is the Western name for the RDS-220, the largest, most powerful weapon ever detonated. The bomb was tested on October 30, 1961, in an archipelago in the Arctic Sea. Developed by the Soviet Union, the bomb had a yield of about 50 megatons. Its detonation released energy equivalent to approximately 1% of the power output of the Sun for 39 nanoseconds of its detonation. The device was scaled down from its original design of 100 megatons to reduce the resulting nuclear fallout. The Tsar Bomba qualifies as the single most powerful device ever utilized throughout the history of humanity."

This comment is way over the top. It's also wrong.

Whoever you are, you read the first page, skimmed the rest, then posted a rant at slashdot. How typical.

At any rate, Nate most certainly did go into the layer 7 stuff--opening up the payload and using that capability to reassemble individual email messages and so on. You just missed it because you were skimming in anticipation of composing that great smack-down post where you display your glorious knowledge of DPI for all of slashdot.

At any rate, instead of giving out reading suggestions, why don't you go back and actually RTFA, chief.

Submission + - Power consumption and the future of computing (arstechnica.com)

Submitted by mrdirkdiggler
mrdirkdiggler writes: ArsTechnica's Hannibal takes a look at how the power concerns that currently plague datacenters are shaping next-generation computing technologies at the levels of the microchip, the board-level interconnect, and the datacenter. In a nutshell, engineers are now willing to take on a lot more hardware overhead in their designs (thermal sensors, transistors that put components into sleep states, buffers and filters at the ends of links, etc.) in order to get maximum power efficiency. The article, which has lots of nice graphics to illustrate the main points, mostly focuses on the specific technologies that Intel has in the pipeline to address these issues.

Astronomers Again Baffled by Solar Observations 299

Posted by CowboyNeal from the back-to-the-drawing-board dept.
SteakNShake writes "Once again professional astronomers are struggling to understand observations of the sun. ScienceDaily reports that a team from Saint Andrew's University announced that the sun's magnetic fields dominate the behavior of the corona via a mechanism dubbed the 'solar skeleton.' Computer models continue to be built to mimic the observed behavior of the sun in terms of magnetic fields but apparently the ball is still being dropped; no mention in the announcement is made of the electric fields that must be the cause of the observed magnetic fields. Also conspicuously absent from the press releases is the conclusion that the sun's corona is so-dominated by electric and magnetic fields because it is a plasma. In light of past and present research revealing the electrical nature of the universe, this kind of crippling ignorance among professional astrophysicists is astonishing."

Submission + - Intel Releases Information on Penryn, Nehalem

Submitted by
Justin Wheeler
Justin Wheeler writes: "Intel has been slowly trickling information on their new Penryn cores (the next release after Merom/Conroe), as well as their upcoming Nehalem cores. From the articles: "At a press meeting today, Intel's Pat Gelsinger also made a number of high-level disclosures about the successor to Penryn, the 45nm Nehalem core. Unlike Penryn, which is a shrink/derivative of Core 2 Duo (Merom), Nehalem is architected from the ground up for 45nm. This is a major new design, and Gelsinger revealed some truly tantalizing details about it. Nehalem has its roots in the four-issue Core 2 Duo architecture, but the direction that it will take Intel is apparent in Gelsinger's insistence that, "we view Nehalem as the first true dynamically scalable microarchitecture." What Gelsinger means by this is that Nehalem is not only designed to take Intel up to eight cores on a single die, but those cores are meant to be mixed and matched with varied amounts of cache and different features in order to produce processors that are tailored to specific market segments.""

Submission + - Scientists Break Speed of Light

Submitted by PreacherTom
PreacherTom writes: Scientists at the NEC Research Institute in Princeton, NJ are reporting that they have broken the speed of light. For the experiment, the researchers manipulated a vapor of laser-irradiated atoms, causing a pulse that shoots about 300 times faster than it would take the pulse to go the same distance in a vacuum, to the point where the pulse seemed to exit the chamber before even entering it. Apparently, Uncle Albert is still resting comfortably: relativity only states that an object with mass cannot travel faster than light. Still, the results are sufficient to merit publication in the prestigious journal, Nature.
