TheMatt writes "CNN.com is reporting about a new conflict perhaps emerging in classrooms: calculators v. PDAs. The article talks about how TI seems to be making their latest calculator more PDA-like, while PDAs are gaining TI-like functionality. A comment on current math education is this quote from the article: "When you have circles and ellipses, there is no way you'd be able to do this without a calculator," Jarvis said. "It helps us visualize what we're doing." Were the compass and geometry uninvented?"

TheMatt writes "In this month's 'Physics World', Robert P. Crease asks the question: what is the most beautiful experiment in physics? Some criteria quoted are that it must change what people thought, must not be too complicated or expensive, and, most importantly, be within the reach of students (which leaves out Stern-Gerlach or Michelson-Morley). He also has a page at BNL reprinting the article, with a place for suggestions from the community on their opinion." I'll nominate a simple one: Foucault's Pendulum. :)

TheMatt writes "In a victory for all those who like the First Amendment, the Colorado Supreme Court today reversed and remanded 'Tattered Cover v. Thornton'. The case concerned the Thornton police attempting to use a search warrant to gain access to the book-buying records of a suspected criminal. The Tattered Cover asserted First Amendment rights and refused to comply with the warrant. It is believed this will be heard by the US Supreme Court eventually." I can only imagine what the Tattered cover's legal bill must be like.

A not-so Anonymous Coward asks: "I'm a student in the dorms at the University of Colorado, where every room is wired with Ethernet. I bought an 802.11b access point and card, and have been using them on the network. 2 days ago, I came home to find out that my network access had been shut off. When I called ITS, they said it was because I was running the access point, and this was against policy. I proceeded to look through CU's site, and read the entire AUP and terms of use. Nowhere in these agreements is any ban on using wireless equipment in-room. When I called back to see when I could get my access turned back on, I was told that the one person that could help me was out sick. So far my access has been off for 2 days and counting, and chances are slim that I'll get it back by Monday, leaving me with a total of 5+ days without access, all for a violation I was unaware of, and had no warning about. Do I have any rights to force them to turn my access on earlier, or do I just sit without access until they get around to helping me?" Now assuming the AP was not completely open to public access, what possible reason is there for such a limitation? Most kids now go to college with laptops, and an AP is probably the best way for them to work (ie, not tied to the wall). My recommendation would be to politely talk to the University IT department? If anyone else has been in similar situations, how did you go about dealing with the University to get your account/email address/network access restored?

TheMatt writes: "An article at PhysicsWeb talks about a proposed project by scientists at FermiLab. The project would involve sending a beam of neutrinos 10,000 km through the earth to a detector at SuperKamiokande. The hope is that passing through so much matter would alter the beam enough to better study CP (charge-parity) violation."

TheMatt writes "A new type of search algorithm is described at NSU. In a way, it is the next generation over Google. It works off the principle that most web pages link to pages that concern the same topic, forming communities of pages. Thus, for academics, this would be great as the engine could find the community of pages related to a certain subject. The article also points out this would be good as an actually useful content filter, compared to today's text-based ones."

TheMatt writes: "The House has just passed the Tauzin-Dingell telecom deregulation bill. This was previously discussed here yesterday." All of the reports seem to agree that there are enough Senators opposed to it that it's not likely to pass this session.

TheMatt writes "Scientists at the University of the Balearic Isles have analyzed the Marvel Universe and found that it is almost like real society. The team studied the statistical properties of each character, the books they were in, and who else appeared in them (through resources like the MCP). While there were some similarities to real society, a close look revealed the artificiality. For example, the MU isn't very clustered, only 1.5x that of a random network; real life is about 10x more clustered. Of course, the realities of comics (the business) are why this occurs. Also, they found the most networked of all Marvel heroes was Steve Rogers, Captain America himself."

TheMatt writes: "There is a summary of a Phys.Rev.Lett. article up at Nature Science Update that describes a design for a 'quantum afterburner' that would improve the efficiency of an Otto engine. It improves the efficiency by using a laser and maser to extract energy from the hot exhaust of the engine. In fact, the process could enhance performance beyond that of the "ideal" Otto engine."

llamalicious writes: "And you thought a Nobel Prize for the discovery of Bose-Einstein Condensates was nifty, SciAm's reporting that scientists are taking this new discovery one step further, and have once more proven that we don't really know anything about quantum physics. This new state is being called a patterned fluid, which could supposedly move the field of quantum computing ahead."

CheshireCatCO writes: "NASA announced on Thursday that it has selected Alan Stern's Pluto mission proposal, named New Horizons, for phase B study and (hopefully) eventual launch in 2006. Alan is himself one of the top experts on Pluto, and his team consists of many other leaders in the field. It should be a good mission, if only they get the money for it." CNN has a story with some background on the mission. NASA is having a hard time deciding whether the Pluto-Kuiper Express is actually going to launch or not.

rbruels writes: "They first made their appearance as clunky high-tech note pads for Captain Kirk (embedded sound warning) and his crew, but back here in the 21st century, the proliferation of the PDA has become a real phenomenon. This story on Unstrung gives a good insight into the evolution of these portable devices, and the factors that will influence their growth in the years to come. A good read. (As a side note, I have yet to purchase a PDA. /me hangs his head in shame.)" More importantly than where they've been though, is what's next for PDAs. What features would you trade the baby for?

Here is your regular irregular dose of Slashdot story updates and obsessive compulsion -- some of it sad, some amusing, some utterly neutral and of no caloric value. For instance: You can win more than 50 of Roblimo's personal dollars if you work really hard, and wait a really long time.

"Kilby ... Kilby .. Kilby ..." [WHACK!] BMagneton writes: "The Nobel Prize for Physics was just awarded to several electronics pioneers, notably Alferov and Kroemer, who invented a bunch of semiconductor device construction methods, and Jack Kilby, who pretty much invented the microchip. The Nobel seems to have gone to a more practical/applied achievement than it usually does." And sconeu writes: "Wired News reports that Jack Kilby have been awarded the Nobel Prize in Physics for his part in the invention of the IC. The prize was split with Herbert Kroemer of UC Santa Barbara and Zhores Alferov of Russia who worked on semiconductor development as well."

And as "Boo," acclaimed international film star Keanu Reeves! Godzookie2k writes: "I was bored out of my mind the other night, and stumbled to boo.com's old site to see what would pop up. Mouth agape, I read: 'Boo.com returns, October 30, 2000.' yippie, you can download the official "boo" screensaver and enter some contest. See for yourself."

Some things are worth bringing back (Old Coke, bermuda shorts), and others may not be. Frankly, I'd never heard of Boo except maybe vaguely in the background until they went bust, time number one. On the other hand, our friend Pee-Wee was pretty funny in Mystery Men, so maybe anything is possible.

A browser for your naked (P)PC; combine with image filtering, stir. Mozilla keeps getting better -- I'm not afraid to show it to anyone right now, for instance -- but it's not exactly lightweight. Anyone who's been following the progress of Galeon may be interested when Markos writes: "Tired of waiting for a lightweight browser, that supports https, frames and all the other good stuff? BrowseX may be what your looking for. 'BrowseX is an Open Source, cross-platform Web Browser written primarily in Tcl.' You can check out the screenshots, features, and download." Or, for those of the Motorola persuasion, you'll be happy to hear that, as sephus writes "Opera for Linux PPC is now available at http://opera.online.no/linux/tgz/ - by popular request from Slashdot readers :) Opera"

Remember, retailers, you better not install these on computer that you know full well are going to be loaded with a god-fearin' American OS-thingie, like Innernet 'Splorer!

"OK, Mr. Gates, Meet Mr. Ponzi. Howdya do?" robl writes "There was a suprisingly under-ranked comment in the Microsoft story yesterday [about Microsoft and Taxes], pointing to the Fool's take on Microsoft's tax situation. It does a great job of clarifying the sfgate article yesterday. You see, Microsoft exercises it's stock options by printing more stock certificates. So they really only lose the cost of the paper and toner to print the stock, and they gain the money from the employees who exercise the options."

In fairness, this is approximately the same system used to fill the hypothetical coffers of the Social Security administration, but MS probably doesn't pay $534.55 for each toner cartridge ;)

My god! And they claim to be secure!? sporri writes: "The OpenBSD homepage has been updated (or downgraded) and now announces "Three years without a remote hole in the default install!" after a root hole was discovered and exploted in a library used by chpass. The sad thing it was fixed in the "current" source tree in June.UpsideToday has an interview with Aaron Campbell." If that's the worst you can say about an OS's security, it's a pretty strong endorsement for it being exemplary in that regard. OpenBSD and Debian get my vote for Most Serious Projects. Comments on the strongest security for (any particular) default Linux distro? Makes me think about Bastille Linux ...

Zen Master Nate writes "You are probably familiar with the BabelFish translation page, where you can enter a phrase and have it translated to or from several languages. Quickly. Inaccurately. This page automatically feeds the results back into the machine, resulting in exponentially erroneous translations. " I've been feeding it quotes from American Pie, Star Wars and Seinfeld. I should get out more.

Kendall Hunter sent us a link to a Mining Co article called 6 Lies About Linux which attempts to address a lot of the FUD that has been popping up in the mainstream media (Does it ever stop?). Things like Linux is Unstable and Linux is Insecure. Good PHB stuff. I wonder if we can get permission to use the PHB for articles of this nature. That would be kinda cool.

Matthew Crosby wrote in to tell us that "there will be an informal little celebration thing on irc.gimp.org port 6666, channel #party. Paul Hart gave me a link to The Worm Farm. It's just weird. Robert Jones wrote in to send us a link to an excellent Linux Help site. Richard Brown sent us a link to a A weather site running Linux. Brian Moore wrote in to send us a link to a story about Communicator 5.0 And finally, Rasmus Lerdorf wrote in to announce that the PHP3 has hit the wire. For those in the dark, PHP is another excellent web page scripting language.

Ryan Kirkpatrick wrote in to give us this link to a CNN article that talks about how you can now print stamps on your computer if you have an internet feed, and (ahem) windows. But it's still pretty cool, and will be much cooler when we have cross platform support.
