Submission + - Has Science Become Corrupted?

An anonymous reader writes: Has Science Become Corrupted?

An award winning science author, Gary Taubes has written a book that pans the medical community's treatment of the obesity epidemic. By itself, that isn't particularly worth our time. Diet books are a dime a dozen and we don't cover them on Slashdot anyway.

What is interesting is that it looks like the medical community is behaving in a very unscientific manner. Taubes points out that the current medical orthodoxy has no basis in research. In fact, all the available research points in quite another (more traditional) direction. Here is BoingBoing's take on the story. You can follow the link from there to an excellent podcast of an interview with Taubes on CBC's 'Quirks and Quarks'.

The medical community seems to defer unthinkingly to authority. For instance, when Britain's most respected paediatrician Sir Roy Meadow came up with a crackpot theory (which I thought we have covered on Slashdot but can't find) that sent innocent people to jail, the courts and the medical community bought it hook line and sinker. Of course, he isn't the only one in that boat. Pathologists all over the world have sent innocent people to jail. There's a case in Ontario, Canada right now of a pathologist who screwed up more than twenty cases and sent several people to jail.

People who study expert behavior have found that people need feedback to maintain their expertise. If they don't get the feedback by the nature of the system or because others are too intimidated/lazy to disagree with them, their behavior becomes non-expert. Ericsson points out that surgeons get better as they get older but mammographers don't. Surgeons get feedback immediately. The patient lives or dies. Mammographers may never find out if they are right or wrong.

So, has medicine become a non-science? Is it mostly a non-science? Somewhat? Can physicists feel smug with their repeatable experiments or do they have some 'splainin to do about string theory?

Submission + - Firefox Memory Hogging Is Due to Fragmentation (pavlov.net)

A beautiful mind writes: It has been long claimed by users that Firefox leaks memory, and on the other hand the developers claimed the number of leaks are minimal. It turns out both groups were right. Stuart Parmenter, one of the authors of the RAMBack extension started investigating and found out that the issue is memory fragmentation. He discovered that while loading about:blank uses 12,589,696 bytes of memory in the test he performed (image), after exercising Firefox with different websites and then clearing the caches with the help of the RAMBack extension the picture is wholly different: "Our heap is now 29,999,872 bytes! 16,118,072 of that is used (up 4,634,208 bytes from before... which caches am I forgetting to clear?). The rest, a whopping 13,881,800 bytes, is in free blocks!"

Submission + - Very Short Duration UPS 1

Tau Neutrino writes: Anybody know about a high-wattage, short-time UPS? I've got a bunch of boxen (5 or so) in my office, and would like to keep them running through the occasional one-or-two-second power outage. Like today's. Anything over say, five seconds, is a real power failure, and I don't expect my systems to survive that. But a second or two? It sure would be nice to weather that storm, and not have to reboot everything and then get it all back to where it was before the power glitch.

Any ideas?

Submission + - New Trend in OSS: Small Teams Develop Better Apps (madpenguin.org)

OSS writes: "MadPenguin.org has a new article up that discusses the latest trend in open source software. The author notes that a lot of OSS developers are keeping their teams small to personally benefit themselves and release better releases in a timely manner to benefit the community. He further writes, "More and more, it seems like open source projects are doing more with less. Even to the tune of more frequent release dates and a solid release each time. Is this a good thing? Should this become the new model for the future of budding, young open source projects? I suppose a lot of this has to do with goals and the future plans of each specific project."
Education

Submission + - Study: firstborns have higher IQ than siblings (nytimes.com)

ghastlygray writes: The New York Times reports an extensive study which shows firstborns tend to have higher IQ than their siblings. The interesting point is that there's strong evidence this has nothing to do with biology, but rather with social conditioning and family dynamics: the researchers discovered that when the eldest child dies at infancy, the second child gets the high IQ. The article cites several competing explanations for this phenomenon.

Submission + - AES may be breakable (and/or have a trapdoor!) (iacr.org)

nodrog writes: A preprint at the International Association for Cryptologic Research (IACR) claims that AES may be susceptible to a new cryptanalysis technique. From the article abstract: — We describe a new simple but more powerful form of linear cryptanalysis. It appears to break AES (and undoubtably other cryptosystems too, e.g. SKIPJACK). The break is "nonconstructive," i.e. we make it plausible (e.g. prove it in certain approximate probabilistic models) that a small algorithm for quickly determining AES-256 keys from plaintext-ciphertext pairs exists — but without constructing the algorithm. Even if this break breaks due to the underlying models inadequately approximating the real world, we explain how AES still could contain "trapdoors" which would make cryptanalysis unexpectedly easy for anybody who knew the trapdoor. If AES's designers had inserted such a trapdoor, it could be very easy for them to convince us of that. But if none exist, then it is probably infeasibly difficult for them to convince us of that.
Privacy

Submission + - Creeper discovers intelligence agencies (gnuheter.com)

mpawlo writes: Patrik Wallstrom of Gnuheter fame has released his new privacy project Creeper. Creeper is basically a picture you place on your blog, website or bittorrent tracker site. Creeper will check the IP of everyone accessing the blog, web site etc and do a lookup into a predefined database over governmental agencies. The result is aggregated on a publicly accessible web site. Creeper will disclose a lot of interesting information regarding how and when governmental officials use their computers and what they monitor at work.

The project was initiated in Sweden a few weeks ago and has already raised serious concerns over privacy matters in Sweden. One of the three letter combination-agencies was discovered monitoring a password protected piracy bittorrent site, i.e. it hacked the web site and kept track of everything happeningthere. This will probably keep happening for six months or so, until all agencies will learn to cover their tracks and use other IP numbers and so forth. Or perhaps the ignorance will continue... Meanwhile, we can all learn what to expect in terms of surveillance and Big Brother tendencies online.

An independent German "Creeper" should be released any day now ("überwach" it is called and is not related to Creeper). Patrik is willing to offer the code to anyone interested in releasing the corresponding service in other countries.

Submission + - Checkers has been Solved

r55man writes: "The Chinook project recently announced that checkers has been solved. Perfect play from both sides results in a draw. From their website:

On May 8, 2007, we were pleased to announce that checkers is now solved. From the standard starting position, Black (who moves first) is guaranteed a draw with perfect play. White (moving second) is also guaranteed a draw, regardless of what Black plays as the opening move. Checkers is the largest game that has been solved to date.

Submission + - Dow Jones Plunge Fueled by Overwhelmed Computers

cloudscout writes: "The Dow Jones Industrial Average dropped over 400 points today. While there were various valid financial reasons for such a decline, some of the blame is being placed on computer systems that couldn't keep up with the abnormally high volume at the New York Stock Exchange and the resulting tremor as they switched over to a backup system. In other words, Dow Jones got Slashdotted."

Submission + - Why Spam Fighting Needs Immediate Change

netconcern writes: CircleID has featured an article by iCAUCE director, Neil Schwartzman "Trench Warfare in the Age of The Laser-Guided Missile", shedding an outstanding light on the seriousness of zombie botnets threatening the infrastructure of the internet. From the article: "The historical development of spam fighting is allowing computer-aware criminals to take the upper hand in the fight against what has now evolved into a completely technologically and organizationally merged threat to public safety. If we do not change our strategic approach immediately, the battle, indeed even the war may be all but lost." A must read!
