Submission + - How the City Hurts your Brain

Hugh Pickens writes: "The city has always been an engine of intellectual life and the "concentration of social interactions" is largely responsible for urban creativity and innovation but now scientists have found that being in an urban environment impairs our basic mental processes and after spending a few minutes on a crowded city street, the brain is less able to hold things in memory and suffers from reduced self-control. "The mind is a limited machine," says psychologist Marc Berman. "And we're beginning to understand the different ways that a city can exceed those limitations." Consider everything your brain has to keep track of as you walk down a busy city street: crowded sidewalks full of distracted pedestrians who have to be avoided; the hazardous crosswalks that require the brain to monitor the flow of traffic and the confusing urban grid, which forces people to think continually about where they're going and how to get there. A city is so overstuffed with stimuli that we need to constantly redirect our attention so that we aren't distracted by irrelevant things and this sort of controlled perception — we are telling the mind what to pay attention to — takes energy and effort. Natural settings don't require the same amount of cognitive effort and a study at the University of Michigan found memory performance and attention spans improved by 20 percent after people spent an hour interacting with nature. "It's not an accident that Central Park is in the middle of Manhattan," says Berman. "They needed to put a park there.""

GCC Compiler Finally Supplanted by PCC? 546

Sunnz writes "The leaner, lighter, faster, and most importantly, BSD Licensed, Compiler PCC has been imported into OpenBSD's CVS and NetBSD's pkgsrc. The compiler is based on the original Portable C Compiler by S. C. Johnson, written in the late 70's. Even though much of the compiler has been rewritten, some of the basics still remain. It is currently not bug-free, but it compiles on x86 platform, and work is being done on it to take on GCC's job."
