يكي از عزيزانم فرموده بودند تا تفاوت خطا و ايراد را برايشان توضيح دهم. مناسب ديدم كه اين مطلب را در اين جا نيز ذكر كنم. Error : A discrepancy between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition. See: anomaly, bug, defect, exception, and […]

As any experienced computer programmer knows, there are unwritten laws that govern software development. However there are no penalties for breaking these laws; rather, there is often a reward. Following are 21 Laws of Computer Programming: 1. Any given program, once deployed, is already obsolete. 2. It is easier to change the specification to fit […]

While everyone knows the theoretical limitations of testing, in practice we devote considerable effort to this task, and would consider it foolish or downright dangerous to skip testing. Other verification techniques, such as static analysis, model checking and proofs, have great potential, but it is unlikely they will ever fully remove the need for testing. […]

در طراحي و ساخت محصولات نرم‌افزاري، سادگي اصلي است بسيار مهم. سادگي راه حل و طراحي معيار مهمي در انتخاب گزينه‌هاي مختلف است. به همين دليل، پيدا كردن راهي براي بازتعريف سادگي با هدفِ اعمال آن در طراحي‌ها و راه‌حلهاي مبتني بر نرم‌افزار موضوع مهمي خواهد بود. John Maeda در كتاب The Laws of Simplicity […]

[Evaluating Software Design Patterns — the “Gang of Four” patterns implemented in Java 6] In this project, we perform an evaluation of the “Gang of Four” design patterns from a practical and experimental point of view using Java 6 as the implementation language. We investigate how Java 6 language features affect the application of the […]

XP pretty much banned use cases, replacing them with the similar sounding “user stories” (see A user story is to a use case as a gazelle is to a gazebo}, and as a result agile zealots have been happy to dump use cases in the trash (along with their project managers, estimates, plans, and architectures). […]

Pattern-based web applications have become popular since they promote reusability and consistency. In few cases, patterns do not produce the desired effect because of lack of experience in applying them. This situation forces one to think of a suitable re-engineering solution for such applications. The objectives of the paper are three fold. It provides a […]
