  • Performance, serve all CSS at once, or as its needed?

    - by yaya3
    As far as I know, these days there are two main techniques used for including CSS in a website. A) Provide all the CSS used by the website in one (compressed) file B) Provide the CSS for required by the elements on the page that is currently being viewed only Positives for A: The entire CSS used on the site is cached on first visit via 1 http request Negatives for A: if it's a big file, it will take a long time to load initially Positives for B: Faster initial load time Negatives for B: More HTTP requests, more files to cache Is there anything (fundamental) that I am missing here?

  • How to process large block data visualization with Flex?

    - by hydra1983
    I know that's a big topic. However, it's better to know some general ideas to handle such problems. I have an application which requires Flex to render statistics data calculated instantly on the client side from a downloaded data set. The problems are: the data set is large and needs more than 10 seconds to be downloaded. there are some filters to control the statistics calculation algorithms. If user changes the filters, it would take a long time to recalculate the result and freeze the UI.

  • Best practice to modularise a large Grails app?

    - by Mulone
    Hi all, A Grails app I'm working on is becoming pretty big, and it would be good to refactor it into several modules, so that we don't have to redeploy the whole thing every time. In your opinion, what is the best practice to split a Grails app in several modules? In particular I'd like to create a package of domain classes + relevant services and use it in the app as a module. Is this possible? Is it possible to do it with plugins? Cheers, Mulone

  • Java: Interface vs Abstract Class (regarding fields)

    - by lifeR00t
    From what I have gathered, I want to force a class to use particular private fields (and methods) I need an abstract class because an interface only declares public/static/final fields and methods. Correct?? I just started my first big java project and want to make sure I'm not going to hurt myself later :)

  • PHP problem with die()

    - by ThinkingInBits
    So, I have this code: } else { $photograph_moderation = new PhotographModeration($this->photograph_id); $photograph_moderation->purgePhotograph(); //eventually take to an error page die('image is not big enough to upload'); } the purgePhotograph() function gets called properly when this condition is met, but the script never appears to die. Is there a reason why die wouldn't get called here? purgePhotograph() has no script killing commands either.

  • Live chat rooms for learning ASP.NET?

    - by pkiyan
    I have come across a couple of sites in the past where a professional programmer would charge you 50 cents per minute or so to chat with them, one on one, and they would answer any questions you have about your choice of programming language. I've been studying ASP.NET 3.5 for a couple of months now and haven't been able to find a service like this for ASP.NET. Any help? A free live chat room for .NET would be of big help too.

  • Rhino Mocks - Do we really need stubs?

    - by Marcelo Oliveira
    If it's possible to change mock behaviour in Rhino Mocks using mock.Stub().Return(), why do we need Stubs anyway? What do we lose by always using MockRepository.GenerateMock()? One big benefit of using Mocks instead of Stubs is that we will be able to reuse the same instance among all the tests keeping them cleaner and straightforward. The moq framework works in a similar way... we don't have different objects for mocks and stubs. (please, don't answer with a link to Fowler's "Mocks aren't stubs" article)

    - by Space Cracker
    We have a big portal that needs user registration to allow them use its services. It's already done in .NET and SOL Server 2005. we are in the phase now of discovering all the problems of the current registration system to build a new robust flexible one that can be extended easily and can be more usable for all services. Could any help me find best practices and design patterns to help me rebuild this using good architectural practices?
