Perl to Python Migration provides a useful and practical resource for programmers that are currently intermediate or expert in using Perl and who want to migrate to using Python for different programming projects. The book achieves this by first giving the user an overview and refresher of the Perl techniques required before giving the information on using Python to achieve the same result. Examples of both Python and Perl will be available on-line on the author's website....

This book is about taking over Perl code, whether written by someone else or by yourself at an earlier time. Developers regularly estimate that they spend 60 to 80 percent of their time working with existing code. Many problems of code inheritance are common to all languages, but the nature of the language makes Perl especially tricky. The reason why is that Perl is similar to English - bursting with irregular verbs, consistent only when it's convenient, borrowing terms from other languages, and providing many ways to say the same thing. In fact, Perl developers have a motto with the abbreviation TMTOWTDI: There's More Than One Way To Do It. While this flexibility is one of the language's strengths, it also makes it extremely difficult when you are f...

Performance is a serious issue. A website must be able to handle the demands of users today, as well as adapt to increasing demands in the future. A website's responsiveness to customers has a direct effect on the success of an organization. Many developers struggle with the complex issues of website performance. This book is a timely guide for enterprise website developers and QA teams. The authors combine their experience analyzing and improving hundreds of websites and show how to conduct an effective performance analysis. They demonstrate how to solve common yet difficult problems, how to monitor tests, and analyze the data collected. Exploring common website types such as brokerage, e-commerce, and B2B, they discuss different performance needs, ...

The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned. Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Small...

Successfully delivering Solutions via Patterns In Patterns-Based Engineering , two leading experts bring together true best practices for developing and deploying successful software-intensive systems. Drawing on their extensive enterprise development experience, the authors clearly show how to deliver on the promise of a patterns-based approach-and consistently create higher-quality solutions faster, with fewer resources. Lee Ackerman and Celso Gonzalez demonstrate how Patterns-Based Engineering (PBE) can help you systematically overcome common obstacles to success with patterns. By bringing discipline and clarity to patterns usage, their techniques enable you to replicate your success broadly and scale patterns to even the largest projects. The...
