The Plastic Fractal Magnet
bedessen writes "An article at NewsFactor summarizes the developments in new plastics that exhibit magnetic fields of fractal dimensions. Whereas a simple bar magnet produces magnetic fields that go from the north pole to the south pole, the fields of the new hybrid plastic sprout like branches of a cactus lined with secondary fields that resemble needles. As these fields become increasingly interlocked, they exhibit a unique kind of order. This intensely ordered structure might one day be key to storing information with a very high density. The researchers behind this are Arthur Epstein, director of the Center for Materials Research at Ohio State University, and Joel Miller, a professor of chemistry at the University of Utah. There's also this PDF overview of the subject, which is quite technical but still readable." -
Slashback: Pliancy, Antennae, Gobe
Slashback tonight with more words on printable, organic transistors; the off-screen saving-Farscape saga, wireless schools, Gobe Productive, and 802.11 antennae to extend you connection. Read on for the details.Go be something! Simon Gauvin writes "As a follow up to your article on Gobe Productive, beunited.org is setting up a donation site to allow people to donate for the purchase of the source to make it open. You can check out the comments here. And our announcement on our main page."
Thinner is better. Factomatic writes "The The New York Times reports that a new polymer by Xerox can be used to make organic transistors on a plastic substrate, which can then be used to inexpensively make light, flexible flat-panel displays for computers, laptops and mobile phones. The material, polythiophene, has achieved performance on electronics benchmarks that is an order of magnitude greater than current polymer materials. It would be used in a new manufacturing process that Xerox is experimenting with to imprint circuits using inkjets." You may remember this story about a company called Rolltronics' research into printable circuitry.
What about reviving The A-Team? Julio Ojeda-Zapata points to his Update: 12/10 01:25 GMT by T : [Errr, not "her" -- sorry about that.] "in-depth article on the Save Farscape movement. Though I have an obvious bias, I believe this is the most comprehensive article on the subject you'll find anywhere. Predictably, I've been deluged by mail from Scapers. I can't say I wasn't warned about that :-)"
Soon, every Thomas Aquinas, Dickinson and Harvard will have one of their own ... Amadaeus writes with news of another all-campus wireless blanketing. "The new University of Ontario Institute of Technology is offering new students an IBM laptop, included with tuition, that is wired with 802.11b access. The reason behind that is the entire campus (read: cafeterias, stairwells, washrooms, "special areas") is covered with the university wireless network hubs. In fact, the university campus itself is designed with charging outlets for every seat in the classroom and ergonomic seating for computer usage for all students.
Either they're trying to improve wireless education or promote in-class LAN parties and all-night wireless hack-o-thons, UOIT is on the right track to some sort of wireless educational future."
Wireless Weapons: A mini-Howitzer or a Liberator. We've run several stories on 802.11 antenna projects that require more time, more esoteric parts, or a bigger budget, and some that don't take much at all. Daniel Marsh writes with another one in this last category: "If you thought Pringles were fun, check out the Cookie Cantenna. Several have been built and tested by Seattle Wireless members and they blow Pringles cans out of the water, as well as taste better."
On the other hand, if convenience is more importance than raw power, you might find this commercialized alternative attractive. The Cantenna is inexpensive (19.95 by itself, plus the cost of a pigtail) and means you don't have to touch a soldering iron, glue, or anything besides a shipping container.

Dual Boot NetBSD And MacOS On An iMac
camateg writes: "I've yet to find news of someone who has done this with a single hard disk, but I'm sure someone has. However, I seem to be the first to make a web page about it having done it, correct me if I'm wrong. This page is just a small tuturial I came up with to describe how I *finally* got things working. No netboot, no ofwboot.xcf on CD, etc. Yeah, I should probably include yaboot to make it complete..." -
