site database‚ get the coordinates‚ and use your GPS receiver to zero in on the geocache location. (Your GPS receiver usually won’t lead you directly to the cache‚ and this is where your powers of observation come into play in locating the cache’s hiding place.) Geocaching is pronounced GEE-oh-cash-ing. It’s not appropriate to pronounce cache as ca-SHAY‚ even if you are French. So unless you want some funny looks‚ stick with good ol’ cash. In a few short years‚ geocaching has grown incredibly popular

space model to full protection with preemptive multi-tasking. Our measurements were enabled by hardware counters in Intel’s Pentium (tm) processor that permit measurement of a broad range of processor events including instruction counts and on-chip cache miss rates. We used both microbenchmarks‚ which expose specific differences between the systems‚ and application workloads‚ which provide an indication of expected end-to-end performance. Our microbenchmark results show that accessing system functionality

I see there is a new adventure sport emerging. It is called Geocaching. Geocaching is a real world game that consists of people hiding caches‚ then others go to find it. Hide and seek for adults basically. There are some sites that offer prizes for finding caches. One asks that you trade a found cache for another one. It is becoming quite a trend. Now forgive me for being niave - but if you are going to burn gas and energy looking for treasure - why wouldn’t it be REAL treasures that you search

reduced power consumption and more efficient simultaneous processing of multiple tasks‚ multi-core processors promise to improve the user experience in home and business environments. Key words- multi core‚ architecture‚ wide dynamic execution‚ smart cache‚ smart memory access. 1. INTRODUCTION One constant in computing is that the world’s hunger for faster performance is never satisfied. Every new performance advance in processors leads to another level of greater performance demands from businesses

-John von Neumann John von Neumann‚ born December 28‚ 1903 was a Hungarian mathematician who made important contributions to computer science‚ von Neumann is best known for his EDVAC (Electronic Discrete Variable Automatic Computer) which opposed the not yet released ENIAC (Electronic Numerical Integrator and Computer). Neumann’s EDVAC design was intended to resolve many of the problems created by the ENIAC’s design. The ENIAC was designed to operate in decimal‚ whereas the EDVAC was designed
