  • Generating text file from database

    - by Goldmember
    I have a requirement to hand-code an text file from data residing in a SQL table. Just wondering if there are any best practices here. Should I write it as an XMLDocument first and transform using XSL or just use Streamwriter and skip transformation altogether? The generated text file will be in EDIFACT format, so layout is very specific.

  • Data access layer using Linq to SQL

    - by Andrei Tanasescu
    I am building a c# - linq - sql server winforms/asp.net application, accessing a database. I would like my business logic layer to be easily testable, and that means not littering it with Linq database queries everywhere. What design patterns/ best practices are available for the following use cases - inserting/updating a new object - searching for an object - loading a bunch of related data into a sort of "presentation" object that could be displayed by various views ?

  • NHibernate (or other worth recommendation ORM), real life example?

    - by migajek
    I'd like to learn database applications in C# and I'm about to select some framework. I heard many recommendations of NHibernate, however I haven't decided yet. Anyway, I'd like to know if there's any real-life example (with sources) of NHibernate in C#, to learn best practices etc.? I know all of them are probably covered in the docs, but working example helps a lot understanding the proper development pattern.

  • C++ Performance/memory optimization guidelines

    - by ML
    Hi All, Does anyone have a resource for C++ memory optimization guidelines? Best practices, tuning, etc? As an example: Class xxx { public: xxx(); virtual ~xxx(); protected: private: }; Would there be ANY benefit on the compiler or memory allocation to get rid of protected and private since there there are no items that are protected and private in this class?

  • Tools and tips for switching CMS

    - by Jimmy
    I work for a university, and in the past year we finally broke away from our static HTML site of several thousand pages and moved to a Drupal site. This obviously entails massive amounts of data entry. What if you're already using a CMS and are switching to another one that better suits your needs? How do you minimize the mountain of data entry during such a huge change? Are there tools built for this, or some best practices one should follow?

  • Why use Hibernate/nHibernate?

    - by ProgrammingPope
    I have found myself doing a lot of work to get nHibernate setup and am left wondering: Why use a framework like Hibernate/NHibernate? I am sure that quite a few people love the framework but I am unclear on the advantages and disadvantages. What are the advantages and disadvantages of lazy loading, and are there other features to Hibernate? Is there anything that makes a framework like this easier to use (best practices, other frameworks, etc)?

  • JSF 2.0 sample or open source application

    - by Theo
    Does anyone know a complete JSF 2.0 sample or open source application using JSF 2.0 features (Facelets, Composite Component, Templates, Ajax, Navigation, etc.). Would be a good reference to learn some best practices. I'm talking about an application that you would also use in production. The only ones I know are ScrumToys and PetCatalog which are delivered with NetBeans 6.9 and are "tutorial-like" applications.

  • Explicit Event add/remove, misunderstood?

    - by Hammerstein
    I've been looking into memory management a lot recently and have been looking at how events are managed, now, I'm seeing the explicit add/remove syntax for the event subscription. I think it's pretty simple, add/remove just allows me to perform other logic when I subscribe and unsubscribe? Am I getting it, or is there more to it? Also, while I'm here, any advice / best practices for cleaning up my event handles.

  • What is the preferred syntax for initializing a dict?

    - by daotoad
    I'm putting in some effort to learn Python, and I am paying close attention to common coding standards. This may seem like a pointlessly nit-picky question, but I am trying to focus on best-practices as I learn, so I don't have to unlearn any 'bad' habits. I see two common methods for initializing a dict: a = { 'a': 'value', 'another': 'value', } b = dict( a='value', another='value', ) Which is considered to be "more pythonic"? Which do you use? Why?

  • How to replicate data with memcache

    - by Industrial
    Hi everyone, I am trying to find good resources on best practices to data replication across memcache servers. What I want to accomplish is that if one of my servers in my pool goes down, the next server in line already has the info set. I have found "repcached" but since I run a WIN32 test environment, I have been unable to install it. So what's our alternatives on how to replicate data between servers? Thanks,

  • Do you use Python mostly for its functional or object-oriented features?

    - by Eric
    I see what seems like a majority of Python developers on StackOverflow endorsing the use of concise functional tools like lambdas, maps, filters, etc., while others say their code is clearer and more maintainable by not using them. What is your preference? Also, if you are a die-hard functional programmer or hardcore into OO, what other specific programming practices do you use that you think are best for your style? Thanks in advance for your opinions!

  • examples of good concurrent programs meant to scale

    - by vishr
    I am looking for seminal and excellent examples of libraries and projects that emulate the good practices of the Java Concurrency in Practice book. The book is marvelous. However, I think supplementing this book reading with code reviews of projects and libraries that make use of the concurrency APIs effectively is necessary to drive the concepts into the brain. One good example of what I am looking for is https://code.google.com/p/concurrentlinkedhashmap/ Can folks help me with finding exemplary, well written code that use the concurrency api well?

  • Why save output until the end?

    - by user509006
    Very quick question about programming practices here: I've always used echo() to output HTML code to the user as soon as it was generated, and used ob_start() at the same time to be able to output headers later in the code. Recently, I was made aware that this is bad programming practice and I should be saving HTML output until the end. Is there a reason for this? What is it, and why isn't output buffering a good alternative? Thanks!
