A Quick Spin Cycle? Or the Wringer?

I am not a fan of stationary bikes, not since I cracked my shin on the flywheel of a Tunturi that Eleanor and I wedged into our Philadelphia bedroom 20 years ago. After many years as a hatrack, it left the family not long ago, fetched by a neighbor from in front of our house. We spent more energy...

The Cruzer Contour's literature contains some impressive performance claims --principally that it has a write speed of 18Mbit/sec and reads at 25Mbit/sec. But it had a difficult time stacking up against the competition.

Why count in binary when you can use hundreds of different digits at once? That&#39;s the principle that has allowed British physicists to develop a video disk that stores far more data than has ever been possible before.

While all the buzz at the rainy US Open is about the need for instant replay, don&#39;t hold your breath. Replay won&#39;t be coming to an umpire chair near you anytime soon.

Rob Thompson has posted about some simple benchmarking he did comparing the speed of a series of "if" statements versus one "switch" with multiple cases.   I got curious about which is actually more efficient at matching a random integer with a set of conditionals. So, I setup a script to create a set of large scripts to test the speed of these different constructs. Using the 'time' command, I measured the speed at which the condition could match a random number.   His results found that the switch statement is generally more than 2 times as fast at matching a simple integer. His tests, however, didn't go through much more than this simple test. It'd be interesting to see what it would do with something more complex (like longer strings or handling the result of an evaluation inside the definition of the switch().
