Major Advances In Knot Theory 230

Posted by kdawson on Saturday November 01, 2008 @03:31PM from the if-it's-not-theory-then-it-must-be-practice dept.

An anonymous reader sends us to Science News, which is running a survey of recent strides in finding an answer to the age-old question: How many ways are there to tie your shoelaces? "Mathematicians have been puzzling over that question for a century or two, and the main thing they've discovered is that the question is really, really hard. In the last decade, though, they've developed some powerful new tools inspired by physics that have pried a few answers from the universe's clutches. Even more exciting is that the new tools seem to be the tip of a much larger theory that mathematicians are just beginning to uncover. That larger mathematical theory, if it exists, may help crack some of the hardest mathematical questions there are, questions about the mathematical structure of the three- and four-dimensional space where we live. ... Revealing the full ... superstructure may be the work of a generation."

"a problem that mobile phone carriers and manufacturers have been struggling with"? They're causing the problem!
For example, my phone has a camera. Why doesn't my phone have a standard USB connector. Why didn't Bell or the manual tell me I can download photos over USB? Why isn't the cable included? (It can't be expensive.) Why am I charged for uploading photos over the air, the same amount as if I sent photos to someone? Why did Bell tell me that uploading is free and then charge me? Why is the camera such a piece of crap in terms of optical quality, JPEG artifacts and user interface?

Superconducting Power Grid Launches In New York 264

Posted by Soulskill on Saturday July 12, 2008 @02:06AM from the so-i-rewired-it dept.

EmagGeek writes "IEEE is running a story about a new superconducting power grid that was energized in April in New York State. The lines operate at 138kV and are cooled to 65-75K to maintain superconductivity. These lines are run underground and can carry 150 times more electricity than copper lines of the same cross section. The project is funded with taxpayer dollars through the Department of Energy." A related story at MarketWatch indicates that this is part of a large-scale effort to upgrade aging infrastructure.

How To Show Code Samples? 485

Posted by Soulskill on Friday July 11, 2008 @07:56PM from the ethics-code dept.

Todd writes "I've been looking around at 'help wanted' advertisements for programming jobs, and almost all of them demand that you not only have professional experience, but also that you show samples of your work. This got me wondering; with the work product, trade secret, and non-disclosure laws/agreements, how exactly can you show work that you've done in a professional capacity to a prospective employer without violating the privacy of the company for which the code was written? For instance, I can't say I've written many BASH scripts (at least, not large ones) for myself personally, but the assortment of such scripts written for my current job is wide and varied indeed. I can't very well just deliver these scripts, or even small portions thereof, to third parties to help demonstrate my scripting prowess. With that in mind, what am I supposed to show them?"

Open WiFi Owners Off the Hook In Germany 215

Posted by timothy on Friday July 11, 2008 @03:30AM from the gefehlt-mir dept.

ulash writes "Ars Technica reports that a court in Germany ruled in favor of an open WiFi network owner stating that if other users use your open WiFi network without your consent and download copyrighted material, you cannot be automatically held responsible for their actions. This does not carry much (if any) weight in the US but here is to hoping that it will at least have a positive impact in the EU as starters."

Second Amendment Questioned 1471

Posted by CowboyNeal on Saturday December 09, 2006 @01:35PM from the lock-and-load dept.

dheera writes "Attorneys in Washington, DC question the scope of the Second Amendment in the first case in nearly 70 years, citing that the right to bear arms only applies to 'a well regulated militia.' 'We interpret the Second Amendment in military terms,' said Todd Kim, the District's solicitor general."
