Comment Use semicolons instead of colons (Score 2, Funny) 306

That's a good idea, but I think there's more money to be saved where people are using entire colons when semi-colons would suffice.

I hear that square-wave signals look WAY better when they travel through way-overpriced copper rather than inexpensive copper. You can totally tell the difference!

Why stop there? I only use copper mined from a small mine in the amazon that has been blessed by a local shaman. You think your picture looks better on expensive copper? Mine comes from the freaking amazon. Like acai berries. Ever heard of them? Yeah.

My TV signal is freaking sweet.

Comment Re:Dark stuff? (Score 2, Funny) 279

I have a similar problem.. but it only applies to dark socks. No matter how frequently I buy new black socks and how INfrequently I buy new white socks, I always end up with "not enough dark socks."

For example, right now I am down to exactly 4 pairs of black socks and about 15-20 pairs of white socks - right after I do my laundry. And I don't even remember the last time I bought white socks.

Maybe black socks mature into white socks? (and XKCD suggested that socks may be the larval stage of wire coat hangers...)

Iron Alloy Could Create Earthquake-Proof Buildings 107

separsons writes "Researchers at Japan's Tohoku University designed a new shape memory metal alloy. The super elastic iron alloy can endure serious stretching and still return to its original shape. The scientists say that once optimized, the material could be used in everything from braces to medical stents to earthquake-proof buildings!"

That's a pretty intriguing idea too, but also in theory it is impossible to get energy out of that because the ratchet will actually slip due to its own thermal energy an average things out.. assuming a long period of time and all parts of ratchet being at thermal equilibrium. If the ratchet is at a lower thermal state then you really just have a miniature heat engine that extracts energy from the thermal difference, which becomes equalized.

Yes, I was really intrigued and confused, after reading the line:

"The new process causes the polymer to conduct heat very efficiently in just one direction,"

I was thinking, wow, is this even possible? If this is true, I think they've just created a material that could behave like a passive air-conditioner, heater, refridgerator, etc., while using NO power, ever. That alone must be breaking some serious laws of thermodynamics..

"One dimension" or "one axis," would have been more appropriate than "one direction."

Comment Re:Inside tire treads? (Score 5, Insightful) 133

Not to crap on your idea, but I don't think that would work. Tires are like pencil erasers. They lose material as you use them. Anything you put on the outside of a tire, that makes contact with the ground, will be rubbed off in less than a few hundred miles. For example, if you look at a new tire, it will typically have little nubs or rubber hairs all over it (these are a result of the molding process). After you drive on them for a few hundred miles, you'll see they get rubbed away/off.

Liberalism and Atheism Linked To IQ Screenshot-sm 33

Pharmboy writes "CNN is reporting that Evolutionary psychologist Satoshi Kanazawa at the the London School of Economics and Political Science correlated data on these behaviors with IQ from a large national US sample and found that, on average, people who identified as liberal and atheist had higher IQs. This applied also to sexual exclusivity in men, but not in women. The findings will be published in the March 2010 issue of Social Psychology Quarterly."

An Exercise To Model a "Solar Radiation Katrina" 225

Hugh Pickens writes in with an update on the warnings we discussed a year back about the dangers of a "solar Katrina." Now NPR is reporting on a tabletop exercise mounted in Boulder, Colorado by government workers attempting to model the effects of a worst-case solar electromagnetic storm. "...an exercise held in Boulder, Colorado, has investigated what might happen if the Earth were struck by a solar storm as intense as the huge storms that occurred in 1921 and 1859 — a sort of solar Katrina — and researchers found that the impact is likely to be far worse than in previous solar storms because of our growing dependence on satellites and other electronic devices that are vulnerable to electromagnetic radiation. 'In many ways, the impact of a major solar storm resembles that of a hurricane or an earthquake,' says FEMA Administrator Craig Fugate, except that a solar Katrina would cause damage in a much larger area — power could be knocked out almost simultaneously in countries from Sweden to Canada and the US. In the exercise, the first sign of trouble came when radiation began disrupting radio signals and GPS devices, says Tom Bogdan, who directs the Space Weather Prediction Center. Ten or 20 minutes later electrically charged particles 'basically took out' most of the commercial satellites that transmit telephone conversations, TV shows, and huge amounts of data we depend on in our daily lives. But the worst damage came nearly a day later, when the solar storm began to induce electrical currents in high voltage power lines strong enough to destroy transformers around the globe, leaving millions of people in northern latitudes without power."

How Easy Is It To Cheat In CS? 684

Pinky3 writes "The New York Times has an article on cheating in CS at Stanford. Here is a classic quote from one student: 'I wasn't even thinking of how it [sic] easy it would for me to be caught,' he said. One interesting strategy discussed is for the professor to make the final count for more of the final grade each time cheating is discovered. Share your experiences as a student and/or as an instructor."

NVIDIA Shows Off "Optimus" Switchable Graphics For Notebooks 102

Vigile writes "Transformers jokes aside, NVIDIA's newest technology offering hopes to radically change the way notebook computers are built and how customers use them. The promise of both extended battery life and high performance mobile computing has seemed like a pipe dream, and even the most recent updates to 'switchable graphics' left much to be desired in terms of the user experience. Having both an integrated and discrete graphics chip in your notebook does little good if you never switch between the two. Optimus allows the system to seamlessly and instantly change between IGP and discrete NVIDIA GPUs based on the task being run, including games, GPU encoding or Flash video playback. Using new software and hardware technology, notebooks using Optimus can power on and pass control to the GPU in a matter of 300ms and power both the GPU and PCIe lanes completely off when not in use. This can be done without being forced to reboot or even close out your applications, making it a hands-free solution for the customer."

Comment Re:Beer cans? (Score 4, Funny) 168

You're thinking too small.

The correct question is, how many beer kegs fit in a 0.5 micrometer fridge?

0.00000000000000000852167911 beer kegs

If the fridge interior happens to be shaped optimally so that no space is wasted and the entire 0.5 micrometer fridge is filled with keg, then.. exactly 8.52167911 * 10^-18 beer kegs (if each keg is 15.5 gallons). [Incase someone wants to out-pedant me: Yeah, I understand you can't optimally shape a 0.5 micrometer fridge for a keg, when the size of 1 unit of keg > 0.5 micrometer fridge.]

Comment Re:Is StarCraft the right game to use for this? (Score 1) 200

Perhaps a game not so dominated by rushing tactics would be a better choice of base game? It definitely seems an interesting idea, but there must be games better suited to an AI contest like this...

Perhaps the concept of shock tactics, such as "rushing" have been evolving for centuries and may just be one of the more effective battle strategies in games and real conflicts. The US has their Shock and Awe, the Germans have their Blitzkrieg, and etc.

Wikipedia's "common interpretation of blitzkrieg": The word, meaning "lightning war", was associated with a deliberate strategy of quick and decisive short battles to deliver a knock out blow to an enemy state before it could fully mobilize.

Sounds like rushing to me. Maybe the fact that rushing is so effective in so many games is because it really is a valid strategy?

1) Repartition the drive so they have a 20-40GB C: drive and partition the remainder for their data on D:.

2) After installing a fresh copy of windows on a freshly formatted drive, I install all their applications (make a list of them before reformatting, so you don't forget details like Adobe Flash Player, Acrobat, etc.). Also do all the windows updates and update all the applications.

3) Move the "My Documents" folder to the D: drive - also go through all the applications and verify that the default saving directories are all on the D: drive.

4) IMMEDIATELY Create a image of the C: partition. I use BartPE/WinPE to boot up outside of windows and "Symantec Ghost" to create an image. You can use any boot disk and any image program you want. Save the image to the D: partition. This image will be a large file or series of files that contains all the data of C:.

5) Now allow them to use their computers for about a week. This will allow them to move things around, customize things to their liking, etc.

6) Come in a week later, check for viruses, malware, etc. If it's clean, then create a SECOND image. This is your "broken in" image.

[6.1) If it's not clean, try to find out what caused the problem - go back to the original image you just made, and copy it back on. Show them what caused it, and tell them not to download whatever program caused it - and come back in another week (go back to step 5).]

7) Now burn your image files to DVDs - or stick them on your personal removable hard drive. Next time they have a computer issue, you can reformat/clean install/AND get back to their original settings/preferences/etc in about 15 minutes, by reimaging their computer. Unless they manage to royally screw things up, you don't even need to bring anything but a boot disk/cd, because their backup images should be on their D: drive. You have backups personally just in case too. ONE LAST THING: Before reimaging, temporarily backup their desktop folder and their Favorites folder in the D: drive. If you want to be really safe, backup the entire user directory in C:\Documents and Settings\. ALSO - do a quick search for documents that may have been saved on the C: drive. Then restore their desktop/favorites after reimaging.

8) After re-imaging, do windows updates.

I do this with my parents and friends the moment anyone needs a clean install. It adds about 30 min onto the process but then allows you to repeat it
