Today I am going to talk about calculating primes. Not the new Transformer movie in which Optimus Prime has to help the humans save the world. I am talking about prime numbers in which the number is only divisable by one and itself. The Algorithm that I am going to introduce is a brute force method for calculating prime numbers. It is great for comparing the computing power of two machines by looking at overall execution times. This routine consists in dividing n by each integer m which is greater…

Text Files
The first type of file that every programmer writes to and reads from is an ASCII text file . A text file is a kind of computer file that is structured as a sequence of lines. Each line is terminated with a special character such as a line feed (LF) in UNIX or a carriage return (CR) and line feed (LF) in MS DOS. I have abstracted the details behind reading and writing files by encapsulating the logic into two classes for your use. The write text file class has…
Application Logging
Error handling and application logging are the most import tasks associated with programming that are over looked by many developers. After a program is released to the field, how do you know if it is performing as it should? Are there issues with the language execution (1-tier), with the database (2-tier) or with the middle-ware (3-tier) ? Many times, issues are only noticed and acted upon after several complaints have been issued. Here is a short list of why you should adding logging to all programs that you create. Traps…
