I'm trying to learn how to extract information from HTML, XML, and if the learning curve is not too high, PDF files. I know some of the basics: urllib2, regular expressions, BeautifulSoup... But for those of you who know your stuff, are there any new modules or techniques that facilitate this somewhat?Start - Why Eiffel Might Be Worth a Second Look || kuro5hin.org - Pentadactyl
The Right Tool For the Job Let's get this out of the way at the start: while Eiffel is worth a second look, it does depend on what you're looking for in a language. Eiffel fits in nicely as an alternative to Java or C++ for developing large applications. If you're leaving Java for more dynamic languages like Ruby then Eiffel isn't going to be for you - you can probably quit reading here.

________ Introduction ________________________________________________ Constraint-based problem solving is a technique for solving hard combinatorial problems that can be stated as variables ranging over a finite domain of non-negative integers, or sets thereof. Problems in this class range from puzzles to real world applications as diverse as scheduling, ware house allocation, configuration and placement. The two basic techniques of constraint programming are constraint propagation and constraint distribution . Constraint propagation is an efficient inference mechanism obtained with concurrent propagators accumulating information in a constraint store . Constraint distribution splits a problem into complementary cases once constraint propagation cannot advance further.

Design by contract ( DbC ), also known as contract programming , programming by contract and design-by-contract programming , is an approach for designing software . It prescribes that software designers should define formal , precise and verifiable interface specifications for software components , which extend the ordinary definition of abstract data types with preconditions , postconditions and invariants . These specifications are referred to as "contracts", in accordance with a conceptual metaphor with the conditions and obligations of business contracts. "Design by Contract" is a registered trademark [ 1 ] of Eiffel Software in the United States.Start - functional programming - What is the single best book on Automated Testing of Websites - Stack Overflow - Pentadactyl
The Art of Unit Testing - "The art of creating Readable, Maintainable and trustworthy tests" by Roy Osherove "Unlike other books on this topic, this book trades theory for real-world examples. It's designed so that you, a working developer, can start writing better unit tests now."
In computing , aspect-oriented programming ( AOP ) is a programming paradigm which aims to increase modularity by allowing the separation of cross-cutting concerns . AOP forms a basis for aspect-oriented software development . AOP includes programming methods and tools that support the modularization of concerns at the level of the source code, while "aspect-oriented software development" refers to a whole engineering discipline.
