Submission + - Snowflake-shaped networks are easiest to mend (newscientist.com)

Z00L00K writes: Networks shaped like delicate snowflakes are the ones that are easiest to fix when disaster strikes.

Power grids, the internet and other networks often mitigate the effects of damage using redundancy: they build in multiple routes between nodes so that if one path is knocked out by falling trees, flooding or some other disaster, another route can take over. But that approach can make them expensive to set up and maintain. The alternative is to repair networks with new links as needed, which brings the price down – although it can also mean the network is down while it happens.

As a result, engineers tend to favour redundancy for critical infrastructure like power networks, says Robert Farr of the London Institute for Mathematical Sciences.

So Farr and colleagues decided to investigate which network structures are the easiest to repair. Some repairs just restore broken links in their original position, but that may not always be possible. So the team looked at networks that require links in new locations to get up and running again. They simulated a variety of networks, linking nodes in a regular square or triangular pattern and looked at the average cost of repairing different breaks, assuming that expense increases with the length of a rebuilt link.

Submission + - Most Popular Suggestion From Web Developers to Microsoft: Stop IE Development

An anonymous reader writes: Few people know that Microsoft offers a suggestion box for developers who build on its various platforms. As can be expected with any feedback site, sometimes things get out of hand. The best example just happened: the Internet Explorer Platform has a suggestion to Stop Internet Explorer Development. To make matters worse, even though the suggestion was posted just yesterday, it's already the most popular submission, and is still climbing very quickly. At the time of publishing, it had over 6,000 votes (more than double the second most popular idea, which is to add automatic updates to older IE versions) and over 50 comments.

How Good Are Charter Schools For the Public School System? 715

theodp writes "'You go to these charters,' gushed Bill Gates in 2010, 'and you sit and talk to these kids about how engaged they are with adults and how much they read and what they think about and how they do projects together.' Four years later, Gates is tapping his Foundation to bring charter schools to Washington State, doling out grants that included $4.25 million for HP CEO Meg Whitman's Summit Public Schools. So what's not to like? Plenty, according to Salon's The Truth About Charter Schools, in which Jeff Bryant delves into the dark side of the charter movement, including allegations of abuse, corruption, lousy instruction, and worse results. Also troubling Bryant is that the children of the charter world's biggest cheerleaders seem never to attend these schools ('A family like mine should not use up the inner-city capacity of these great schools,' was Bill Gates' excuse). Bryant also cites Rethinking Schools' Stan Karp, who argues that Charter Schools Are Undermining the Future of Public Education, functioning more like deregulated 'enterprise zones' than models of reform, providing subsidized spaces for a few at the expense of the many. 'Our country has already had more than enough experience with separate and unequal school systems,' Karp writes. 'The counterfeit claim that charter privatization is part of a new 'civil rights movement', addressing the deep and historic inequality that surrounds our schools, is belied by the real impact of rapid charter growth in cities across the country. At the level of state and federal education policy, charters are providing a reform cover for eroding the public school system and an investment opportunity for those who see education as a business rather than a fundamental institution of democratic civic life. It's time to put the brakes on charter expansion and refocus public policy on providing excellent public schools for all.'"

Comment Re:That's overly simplistic - population density k (Score 1) 569

Can you answer this WITHOUT YELLING?:

Which scenario has the greater cost/revenue benefit? (thus allowing for lower costs to consumer):

1) Wiring up and connecting 5 towns in a 100 square mile radius, each with a population of 10,000 people. That line you run out to each town services 10,000 people each!

2) Wiring up and connecting 5 towns in a 100 square mile radius, each with a population of 1,000 people. That same line to each line only services 1,000 people.

Both scenarios require similar amounts of infrastructure in place, but one scenario offsets the cost with more revenue. If you can do that, you can lower the cost per customer... Higher population density = more revenue/cost.

Except France's small villages are extremely close to each other.

France (not including it's territories) spans 213,010 square miles and has a population of 63,460,000. A population density of 297.92 people per square mile.

Comparatively, If you take the US state I live in and an adjoining state (Arizona and New Mexico), they span a combined 235,587 square miles (comparable to France) and host a combined population of 8,638,538. A population density of 36.6 per square mile. And like France, there are only a few large cities (large is relative).

Comment Re:When did CEOs get to dictate tax policy? (Score 1) 122

There is actually an even easier way to do this:

1) Make the Tax flat.. no exceptions for any "type" including food, health.

2) Only tax new goods and services: used car-> no tax

3) At a local level figure out what a family/person pays for the bare necessities: enough food, rent, basic healthcare, transportation costs etc.. every month (Have them publish the formula). Then figure the amount of tax there would be on that. Electronically transfer that amount every month in the form of a prebate to everyone.

Keep in mind that at this point you are taxing consumption, and not income so the idea of "wealthier" people paying a lower effective tax rate only applies if you reintroduce income (or somehow "wealth") into the equation. (Remember: income != wealth != consumption)

Poorer people are less likely to buy a BRAND NEW house, or car and so pay no tax on it. They are less likely to buy that $18 bowl of granola or $50 t-shirts. If someone wants to buy caviar for all there meals... they pay tax on it and the prebate probably won't cover even a slight bit of it. Politicians can still monkey with the prebate amounts, but as it would be law/amendment I cannot see how to permanently and in perpetuity fix the law as untouchable. However, once you stop taxing income, it becomes harder to track income (I think this is a good thing)

How the U.S. Sequester Will Hurt Science and Tech 522

Later today, the U.S. government will enter the sequestration process, a series of across-the-board budget cuts put into place automatically because U.S. politicians are bad at agreeing on things. "At that moment, somewhere in the bowels of the Treasury Department, officials will take offline the computers that process payments for school construction and clean energy bonds to reprogram them for reduced rates. Payments will be delayed while they are made manually for the next six weeks." The cuts will directly affect science- and tech-related spending throughout the country. Tom Levenson writes, '[s]equester cuts will strike bluntly across the scientific community. The illustrious can move a bit of money around, but even in large labs, a predictable result will be a reduction in the number of graduate student and post – doc slots available — and as those junior and early-stage researchers do a whole lot of the at-the-bench level research, such cuts will have an immediate effect on research productivity. The longer term risk is obvious too: fewer students and post-docs mean on an ongoing drop from baseline in the amount of work to be done year over year.' The former director of the National Institute of Health says it will set back medical science for a generation. NASA Administrator Charles Bolden has laid out how the cuts will affect the U.S. space program. He said, "The Congress wasn’t able to do what they were supposed to do, so we’re going to suffer." The sequester will also prevent billions of dollars from flowing into the tech industry. This comes at a time when there's a pressing need in the tech sector for professionals versed in the use of Linux, and salaries for those workers are on the rise.

For either/both sides to call shenanigans when the vote does not go their way. I wonder if someone has done a study on the amount of press voter fraud gets vs. party election outcome and if there is as stark of a difference as I perceive. And if people really think that one party only wins when they "cheat", does that just reinforce myopic visions of political views (i.e. Most people think the way I do and so the only explanation is fraud)?

Submission + - End of the line for Spamcop?

fl!ptop writes: Since about the middle of June, spam reporting tool Spamcop has been under what appears to be a very well coordinated and executed DDoS attack. As a paying member of many years, I've been experiencing unusually long delays, 404's, proxy errors, gateway timeouts, and other strange errors when trying to submit spam reports. There is a very long thread in the 'general' forum discussing the issue. Like some of the commentators, I'm wondering how a company with resources like Cisco (owner of Spamcop) could let this problem persist for so long. Admin posts to the discussion thread keep indicating the problem is fixed, there's a big backlog, it should be working, etc. but that's not the case from my point of view (and may others). Could it be because Cisco doesn't care about the service anymore and are not giving it their full attention? Is this the beginning of the end for Spamcop?

Submission + - Space Worms Live Long and Prosper (discovery.com)

astroengine writes: "A microscopic worm used in experiments on the space station not only seems to enjoy living in a microgravity environment, it also appears to get a lifespan boost. This intriguing discovery was made by University of Nottingham scientists who have flown experiments carrying thousands of tiny Caenorhabditis elegans (C. elegans) to low-Earth orbit over the years. It turns out that this little worm has genes that resemble human genes and of particular interest are the ones that govern muscle aging. Seven C. elegans genes usually associated with muscle aging were suppressed when the worms were exposed to a microgravity environment. Also, it appears spaceflight suppresses the accumulation of toxic proteins that normally gets stored inside aging muscle. Could this have implications for understanding how human physiology adapts to space?"

Submission + - Student creates world's fastest shoe with a printer (geek.com)

An anonymous reader writes: Engineer and designer Luc Fusaro from the Royal College of Art in London has developed the prototype of a running shoe that can be uniquely sculpted to any athlete’s foot. It’s as light as a feather too, weighing in at 96 grams. The prototype is aptly named, Designed to Win, and is 3D printed out of nylon polyamide powder, which is a very strong and lightweight material. The manufacturing process uses selective laser sintering (SLS), which fuses powdered materials with a CO2 laser to create an object. This process means 3D scans can be taken of the runner’s foot so as to ensure the show matches the shape perfectly. Fusaro can also change the stiffness of the soles according to the athlete’s physical abilities.

The shoe can improve performance by 3.5%, meaning a 10 second 100-meter sprinter could see his time drop by 0.35 seconds, which is a huge time saving relatively speaking. Imagine if Usain Bolt put a pair of these running shows on.
