How To Enter Equations Quickly In Class? 823

Posted by timothy from the napkins-and-a-digital-camera dept.
AdmiralXyz writes "I'm a university student, and I like to take notes on my (non-tablet) computer whenever possible, so it's easier to sort, categorize, and search through them later. Trouble is, I'm going into higher and higher math classes, and typing "f_X(x) = integral(-infinity, infinity, f(x,y) dy)" just isn't cutting it anymore: I need a way to get real-looking equations into my notes. I'm not particular about the details, the only requirement is that I need to keep up with the lecture, so it has to be fast, fast, fast. Straight LaTeX is way too slow, and Microsoft's Equation Editor isn't even worth mentioning. The platform is not a concern (I'm on a MacBook Pro and can run either Windows or Ubuntu in a virtual box if need be), but the less of a hit to battery life, the better. I've looked at several dedicated equation editing programs, but none of them, or their reviews, make any mention of speed. I've even thought about investing in a low-end Wacom tablet (does anyone know if there are ultra-cheap graphics tablets designed for non-artists?), but I figured I'd see if anyone at Slashdot has a better solution."

Feed Engadget: Google hits Android ROM modder with a cease-and-desist letter (engadget.com)

From feed by engfeed
So this is interesting: apparently Google's hit the developer of the Cyanogen modded Android ROM with a cease-and-desist letter, asking him to stop distributing the closed-source Google apps like Gmail, Maps, and YouTube. What's a little strange is that Cyanogen is targeted at "Google Experience" devices like the G1 and myTouch, so it's not like Google is really protecting anything here -- leading us to wonder if they're just using the copyright argument to shut down a popular mod that's tempted over 30,000 users into rooting their phones. That's just speculation on our part, though -- the dev says he's trying to open a dialogue with Google, so perhaps we'll find out some more answers soon.

On-Body Circuits Create New Sense Organ 289

Posted by Soulskill from the don't-tag-this-porn dept.
destinyland writes "In 'My New Sense Organ,' a science writer tests 'a new sense' — the ability to always know true north — by strapping a circuit board to her ankle. It's connected to an electronic compass and an ankle band with eight skin buzzers. The result? 'I had wrong assumptions I didn't know about ... I returned home to Washington DC to find that, far worse than my old haunt San Francisco, my mental map of DC swapped north for west. I started getting more lost than ever as the two spatial concepts of DC did battle in my head.' The device also detects 'the specific places where infrastructure interferes with the earth's magnetic fields.'

"My experience with memtest is you can trust the results if it says the memory is bad, however if the memory passed it could still be bad."

This has been my experience too. I hate to recommend Microsoft products but I've found that Windows Memory Diagnostic to be more thorough than memtest86. It has found bad memory that memtest86 missed on more than one occasion.

Is this the spec to which you refer? http://www.certif.com/index.html If it is then you are incorrect about it being open source. A license is required to run it. It is possible to obtain the code so you can build it, but sharing it is definitely not allowed. The macros you write for it, however, are as open as you'd like them to be.

Scientists Discover Proteins Controlling Evolution 436

Posted by samzenpus from the let-the-flamewar-begin dept.
Khemisty writes "Evolutionary changes are supposed to take place gradually and randomly, under pressure from natural selection. But a team of Princeton scientists investigating a group of proteins that help cells burn energy stumbled across evidence that this is not how evolution works. In fact, their discovery could revolutionize the way we understand evolutionary processes. They have evidence that organisms actually have the ability to control their own evolution."

Boston University Working On LED Wireless Networks 179

Posted by timothy from the line-of-sight dept.
Madas writes "This article on Absolute Gadget details how researchers at Boston University's College of Engineering are working on devloping wireless networks that use LED lights instead of normal radio waves. This research apparently has other uses in the automobile industry. Apparently the LEDs could warn you if the driver in front has put the brakes on so could avoid hitting the car in front. Personally, I'd use the vision balls that are in my thought box."

How Can Nerds Make a Difference In November? 950

Posted by kdawson from the our-own-sweet-way dept.
Scott Aaronson offers an intriguing call for ideas on how nerds can supercharge the political process this year. He's clearly an Obama admirer and phrases his challenge this way: "What non-obvious things can nerds who are so inclined do to help the Democrats win in November?" But the question itself is not inherently partisan. The analogy Aaronson gives is to the Nadertrading idea in 2000 (which we discussed at the time). What's the Nadertrading for 2008? "The sorts of ideas I'm looking for are ones that (1) exploit nerds' nerdiness, (2) go outside the normal channels of influence, (3) increase nerds' effective voting power by several orders of magnitude, (4) are legal, (5) target critical swing states, and (6) can be done as a hobby."
