  • System requirement specification vs functional one - separate docs?

    - by user970696
    A lot of sources (e.g. Wikipedia) mentiones System requirement specification and Functional specification as two separate entities. However, Wiegers in his book writes: The software requirements specification is sometimes called a functional specification, a product specification... This is very confusing for me as I thought FS describes just functions while SRS whole system. From this point of view, FS would contain both non functional and functional requirements and everything else.

  • Are there architecture smells?

    - by C. Ross
    There are tons of resources on the web referring to and listing code smells. However, I've never seen information on architectural smells. Is this defined somewhere, and is there a list available? Has any formal research been done into architecture defects, and their impact on project speed, defects, and the like? Edit: I wasn't really looking for a list in the answers, but documentation (on the web or in a book) about architecture smells.

  • Why avoid Java Inheritance "Extends"

    - by newbie
    Good day! Jame Gosling said “You should avoid implementation inheritance whenever possible.” and instead, use interface inheritance. But why? How can we avoid inheriting the structure of an object using the keyword "extends", and at the same time make our code Object Oriented? Could someone please give an Object Oriented example illustrating this concept in a scenario like "ordering a book in a bookstore?" Thank you in advance.

  • Ranking with PowerPivot – a different approach

    - by Marco Russo (SQLBI)
    Alberto Ferrari wrote an interesting post about a “different approach” in creating a ranking measure with PowerPivot . If you know DAX or you read our book , you will find that a DAX expression can solve the issue. However, such a formula is more complex than necessary. The next version of PowerPivot might have more built-in DAX functions and should solve the ranking need with a simpler formula. In the meantime, it is interesting to know a different approach that relies on Excel skills instead of...(read more)

  • Should I use scaffolding or not in Ruby on Rails?

    - by dpacmittal
    I'm learning Ruby on Rails for a new project of mine. I am referring the book 'Agile Web Development with Rails' which shows how to build a shopping cart and they use scaffolding. I'm pretty familiar with MVC architecture and have used several frameworks in PHP to build applications. I've never used scaffolding and I'm not sure if that's the best way to start building an application. Experienced users, please suggest if I should be using scaffolding or should I code manually.

  • Encapsulating code in F# (Part 1)

    - by MarkPearl
    I have been looking at F# for a while now and seem a few really interesting samples and snippets on howto’s. This has been great to see the basic outline of the language and the possibilities, however a nagging question in the back of my mind has been what does an F# project look like? How do I code group code in F# so that it can be modularized and brought in and out of a project easily? My Expert F# book has an entire chapter (7) dedicated to this and after browsing the other chapters of the book I decided that this topic was something I really wanted to know more about now! Because of my C# background I keep trying to think in F# of objects. So to try and get a clearer idea of how to do things the F# way I am first going to take a very simplified C# example and try to “translate” it. using System; namespace ConsoleApplication1 { namespace ExampleOfEncapsulationInCSharp { class Program { static void EncapsulatedVariableInAMethod() { int count = 10; Console.WriteLine(count); } static void Main(string[] args) { EncapsulatedVariableInAMethod(); Console.ReadLine(); } } } } From the above example the count integer is encapsulated within EncapsulatedVariableInAMethod method. You couldn’t access the count variable from outside the scope of its parent method but have full access to it within the method. Lets look at my F# equivalent… open System let EncapsulatedVariableInAMethod = let count = 10 Console.WriteLine(count) () EncapsulatedVariableInAMethod Console.ReadLine()   Now, when I first attempted to write the F# code I got stuck… I didn’t have the Console.WriteLine calls but had the following… open System let EncapsulatedVariableInAMethod = let count = 10 EncapsulatedVariableInAMethod Console.ReadLine()   The compiler didn’t like the let before the count = 10. This is because every F# expression must evaluate to a value. If I did not want to make the Console call, I would still need to evaluate the expression to something – and for this reason the Unit Type is provided. I could have done something like…. open System let EncapsulatedVariableInAMethod = let count = 10 () EncapsulatedVariableInAMethod Console.ReadLine()   Which the compiler would be happy with…

  • WPF4 Unleashed - how does converting child elements work?

    - by Kapol
    In chapter 2 of the book WPF4 Unleashed the author shows an example of how XAML processes type conversion. He states that <SolidColorBrush>White</SolidColorBrush> is equivalent to <SolidColorBrush Color="White"/> , because a string can be converted into a SolidColorBrush object. But how is that enough? It doesn't make sense to me. How does XAML know to which property should the value White be assigned?

  • Recommended readings for a sofware construction mini-course [on hold]

    - by Aivar
    I'm going to organize a mini-course for CS students who have completed CS1 (Python) and CS2 (Java). I'd like to show them more principled approach to programming practice and design, something along the lines of McConnel's Code Complete. If I had enough copies of Code Complete, I would assign some readings from that book. Can you recommend some freely available material (books, blog posts, articles, essays) for such a course? (I'd prefer to avoid topics specific to OOP and focus on more universal principles.)

  • What is lightweight lock in distributed shared memory systems?

    - by Kutluhan Metin
    I started reading Tanenbaum's Distributed Systems book a while ago. I read about two phase locking and timestamp reordering in transactions chapter. While having a deeper look from google I heard of lightweight transactions/lightweight transactional memory. But I couldn't find any good explanation and implementation. So what is lightweight memory? What are the benefits of lightweight locks? And how can I implement them?

  • Best books on Managing a Software Development Team? [closed]

    - by JohnFx
    The canonical books on software development is fairly well established. However, after reading through a dreadful book full of bad advice on managing programming teams this weekend I am looking for recommendations for really good books that focus on the management side of programming (recruiting, performance measurement/management, motivation, best practices, organizational structure, etc.) and not as much on the construction of software itself. Any suggestions?
