Visitors To US Now Required To Register Online 734

mytrip sends a reminder that starting today, visitors to the US from 35 visa-waiver countries will be required to register online with the Department of Homeland Security in advance. The DHS is asking people to go online for the ESTA program 72 hours before traveling, but they can register any amount of time ahead. Approval, once granted, is good for 2 years. DHS says that most applications are approved in 4 seconds. If an application is rejected, the traveler will have to go to a US embassy and get a visa. CNet reports that information from applications will be retained for 12 years, and eventually up to 75 years.

NASA Outsources ISS Resupply To SpaceX, Orbital 151

DynaSoar writes "NASA has signed two contracts with US commercial space ventures totaling $3.5 billion for resupply of the International Space Station. SpaceX will receive $1.6 billion for 12 flights of SpaceX's planned Dragon spacecraft and their Falcon 9 boosters. $1.9 billion goes to Orbital for eight flights of its Cygnus spacecraft riding its Taurus 2 boosters. Neither of the specified craft has ever flown. However, the proposed vehicles are under construction and based on proven technology, whereas NASA has often contracted with big aerospace companies for services using vehicles not yet even designed."

Not All Cores Are Created Equal 183

joabj writes "Virginia Tech researchers have found that the performance of programs running on multicore processors can vary from server to server, and even from core to core. Factors such as which core handles interrupts, or which cache holds the needed data can change from run to run. Such resources tend to be allocated arbitrarily now. As a result, program execution times can vary up to 10 percent. The good news is that the VT researchers are working on a library that will recognize inefficient behavior and rearrange things in a more timely fashion." Here is the paper, Asymmetric Interactions in Symmetric Multicore Systems: Analysis, Enhancements and Evaluation (PDF).

I'm 24, but I tend to be absentminded and have a horrible memory, especially as it relates to things outside my daily routine. I read a book recently though that was astounding. The Memory Book. The concepts in this book can be used to memorize basic information (I memorized all the US presidents in an hour or so), appointments, people's names, etc. I wish I had read this back before high school. It is something everybody should know. This is starting to sound like an advertisement. Umm...BUY TODAY!!!

Some questions were obviously chosen because there are specific misconceptions regarding that issue. For example, the president has the ability to declare war, doesn't he? After all, our presidents have been sending troops all over the world for decades without congressional approval. But that is wrong. Only congress has that power. "Separation of church and state" being granted by the constitution is another common misconception.

Wrong answers to questions on central planning vs. free markets, however, are due to a devotion to a philosophy that is just wrong. I'm sure those elected officials were shocked that they got that one incorrect.

So yes, you would expect that no group could do worse than 25% when given 4 choices, but when the questions are chosen with misconceptions in mind, it becomes far more likely.

Same here. I have to have a fan on to sleep well. But not because of noise, because of silence. I need white noise to sleep. I can't sleep in absolute silence.

I used to live 20 feet from train tracks. On the other side of the tracks were a parking lot and a baseball field (college). Fighter jets often flew low altitude bombing runs (or something) right over me. Not too mention yelling drunk college kids. I could sleep fine through all of that...but a silent room kills me.
