quot;How to Build Your Own Arcade Machine from an Old Computer" Did you find yourself feeding quarters to arcade machines in the '80s and '90s? Do you have any old computers -- or even computer parts -- sitting around taking up space? Do you want to relive those great arcade moments in the comfort of your own home? It's all possible thanks to emulators. The purpose of MAME is to preserve old arcade games. The MAME software emulates that hardware, including the arcade machine's memory, processors or central processing unit (CPU) and input/output (I/O) spaces. But let's assume you have a big pile of arcade game chips sitting in a box at home. Of course you could just run the emulator and ROMs on your computer and play games like that.
The world's 23 toughest math questions | NetworkWorld.com C It sounds like a math phobic's worst nightmare or perhaps Good Will Hunting for the ages. Those wacky folks at he the Defense Advanced Research Projects Agency have put out a research request it calls Mathematical Challenges, that has the mighty goal of "dramatically revolutionizing mathematics and thereby strengthening DoD's scientific and technological capabilities." The challenges are in fact 23 questions that if answered, would offer a high potential for major mathematical breakthroughs, DARPA said. So if you have ever wanted to settle the Riemann Hypothesis, which I won't begin to describe but it is one of the great unanswered questions in math history, experts say. DARPA perhaps obviously states research grants will be awarded individually but doesn't say how much they'd be worth. So if you're game, take your pick of the following questions and have at it.

Project Euler is a series of challenging mathematical/computer programming problems that will require more than just mathematical insights to solve. Although mathematics will help you arrive at elegant and efficient methods, the use of a computer and programming skills will be required to solve most problems. The motivation for starting Project Euler, and its continuation, is to provide a platform for the inquiring mind to delve into unfamiliar areas and learn new concepts in a fun and recreational context. Who are the problems aimed at? The intended audience include students for whom the basic curriculum is not feeding their hunger to learn, adults whose background was not primarily mathematics but had an interest in things mathematical, and professionals who want to keep their problem solving and mathematics on the edge. Can anyone solve the problems? The problems range in difficulty and for many the experience is inductive chain learning. What next?
