High Fructose Corn Syrup Causes Bigger Weight Gain In Rats 542

Posted by timothy
from the subsidies-cause-fatter-corn-farmers dept.
krou writes "In an experiment conducted by a Princeton University team, 'Rats with access to high-fructose corn syrup gained significantly more weight than those with access to table sugar, even when their overall caloric intake was the same.' Long-term consumption also 'led to abnormal increases in body fat, especially in the abdomen, and a rise in circulating blood fats called triglycerides.' Psychology professor Bart Hoebel commented that 'When rats are drinking high-fructose corn syrup at levels well below those in soda pop, they're becoming obese — every single one, across the board. Even when rats are fed a high-fat diet, you don't see this; they don't all gain extra weight.'"

Right. They are ignoring the huge volume of legitimate mail that hotmail/msn silently deletes in violation of the RFCs.

Hotmail doesn't represent the majority of e-mail accounts, and usually it seems to be down solely to the incompetence of whoever is administering hotmail, rather than intentionally violating RFC. Same difference, I suppose, but it's certainly not a majority of the legitimate e-mail they get to them, anyway.

+ - Simple Machine Forum Co-Founder Speaks Out-> 1

Submitted by SMF Friend
SMF Friend (1298951) writes "It seems there's something going down at SimpleMachines.org, home of the Simple Machines Forum. Within the past week, a new website has cropped up with dozens of former developers and project management in heated discussions over events that transpired last Saturday. A statement has been released by former Developer and Co-Founder Jeff Lewis, which chronicles the life and hardships of SMF and includes a letter from 30 current and former SMF Team Members asking for the removal of three of SMF's Managers.

"Over seven years ago my friend Joseph Fung and I decided the web needed an alternative to the leading PHP forum package out there. We created a PHP fork of perl based YaBB and after working with what we called YaBB SE for a bit, we re-branded as SMF, or Simple Machines Forums, along with a new core of code written by a developer who called himself [Unknown]. After seven years its crumbling but why?"

Other former SMF contributors are already picking up the story (Original German version).

As of writing this, the SMF community has begun banning members who link to blog post on their official forums, including Co-Founder Jeff Lewis."

Wrong - the auto-update feature is new to 7.x, so actual sites running 6.x (or earlier) doesn't benefit from it. Also, the new feature will only install and update modules and themes, not 'core', so I'm guessing updating core from 7.0 to 7.1 is probably going to require about as many manipulation steps as you need to go from 6.14 to 6.15. I don't have a lot of experience, but I would not say it's "extremely easy": the stable 6.x version requires you to do a lot of file and configuration manipulation just to go from 6.14 to 6.15 (if you follow all the recommended steps, which I did for my test site recently). It's not hard, it's just not automated.

If you set everything up properly, you just overwrite everything not in the sites directory with the new files, and then possibly run the database update script. Quite trivial.

I actually set up Drupal sites by symlinking to a main drupal installation for files and common modules. All the benefit of the /sites directory without having to use a single root favicon, deal with script-loaded sitemaps, etc.

Ocean-Crossing Dragonflies Discovered 95

grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

PHP's primary issue in the database department is it doesn't have a clean way of say, maintaining prepared statement declarations across connection instances. Which is frustrating. APC's handling of shared memory is not the best, either, and the memcached extensions for it need polish. Don't get me started on how PHP treats constants.

Where PHP really fails, however, is in memory usage. It takes up dozens of times as much RAM as a well-built C program would. Facebook would not reduce their computer count by a factor of ten because PHP is that much less efficient at its job, but because more memory would be available in a given machine to handle more instances at once.

Note: PHP 5.3 addresses a lot of this, but though I haven't tested it, I doubt the memory efficiency of PHP is going to get far into the double-digit percentiles of C++ in one shot.

The Perfect Way To Slice a Pizza 282

Posted by samzenpus
from the equal-distribution-of-the-pie dept.
iamapizza writes "New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article; 'The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if two people take turns to take neighboring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?' This is useful, of course, if you're familiar with the concept of 'sharing' a pizza."

You could even consider such basic human decency to be an investment. If you give the guy without a coat one, he'll be a more productive worker in turn. And if he like you is not an asshole, you may get something out of it.

Health care is a particularly blatant example: we could insure every uninsured for the cost of denying insurance, several times over. The rest of the money would be sufficient to pull the US out of recession, merely through having enough of an edge in labor efficiency to eliminate our trade deficit.

None of those calculations make any assumption about having a more efficient work force along with a healthier work force. Every hour a poor person spends in agony is an hour they are not working to their fullest potential.

Super-Earths Discovered Orbiting Nearby, Sun-Like Star 242

Posted by Soulskill
from the i-for-one dept.
likuidkewl writes "Two super-earths, 5 and 7.5 times the size of our home, were found to be orbiting 61 Virginis a mere 28 light years away. 'These detections indicate that low-mass planets are quite common around nearby stars. The discovery of potentially habitable nearby worlds may be just a few years away,' said Steven Vogt, a professor of astronomy and astrophysics at UCSC. Among hundreds of our nearest stellar neighbors, 61 Vir stands out as being the most nearly similar to the Sun in terms of age, mass, and other essential properties."
