  • PHP: Object Oriented Programming -> Operator

    - by oman9589
    So I've been reading through the book PHP Solutions, Dynamic Web Design Made Easy by David Powers. I read through the short section on Object Oriented PHP, and I am having a hard time grasping the idea of the - operator. Can anyone try to give me a solid explanation on the - operator in OOP PHP? Example: $westcost = new DateTimeZone('America/Los_Angeles'); $now->setTimezone($westcoast); Also,a more general example: $someObject->propertyName Thanks

  • Specifics of List Membership

    - by phasetwenty
    How does Python (2.6.4, specifically) determine list membership in general? I've run some tests to see what it does: def main(): obj = fancy_obj(arg='C:\\') needle = (50, obj) haystack = [(50, fancy_obj(arg='C:\\')), (1, obj,), needle] print (1, fancy_obj(arg='C:\\'),) in haystack print needle in haystack if __name__ == '__main__': main() Which yields: False True This tells me that Python is probably checking the object references, which makes sense. Is there something more definitive I can look at?

  • SOAP VS REST PRAGMATIC CASE STUDIES ?

    - by asksuperuser
    I'm not satisfied with the answers given by the SOAP vs REST questions notably here: http://stackoverflow.com/questions/106546/performance-of-soap-vs-xml-rpc-or-rest because it's just general philosophical answers and not pragmatic answers with some study cases. Nobody can give precise cases of when soap would be more suitable than rest, especially as for performance point of view ? For example let's say I have a flash client for a financiall simulation wizard calling legacy code. Should I use SOAP or REST ? Why ?

  • How can I change timezone in Wordpress 2.9.2?

    - by newbie
    I have changed timezone from General Settings, but that had no effect, time still shows as default UTC time zone. Then I changed timezone in wp-settings.php with date_default_timezone_set('Europe/Helsinki'); but that din't work either. What could be wrong with my settings and why isn't timezone changing?

  • Large or small company?

    - by James
    Hi, I would like to hear some opinions regarding working in small companies versus large corporations. So far, my personal experience has been that esp. for junior programmers small companies have given a more solid background, as follow-up is with experienced workers. In larger corporations on the other hand, the experienced have already worked they way way out of reach. Is this a general feeling or just my bad experience?

  • Default App Icon not appearing in iOS Simulator

    - by user577466
    I have searched quite a lot for an answer to this problem. If I have a general application, HelloWorld, and create an interface and then go to test it, then click on the Home button, not even the default grey/white icon is there like it's supposed to be. Anyone have any ideas why? I've even tried specifying a custom icon in the Info.plist file, but still nothing... I've got the latest version of Xcode and the SDK as well. (3.25 - 4.2)

  • Usability of an endless/infinite scroll

    - by Anton Gogolev
    What are pros and cons of this technique (see Softfolio for an example). Two things I personally thought of are as follows: Impossible to tell someone where an item of interest is located (like, you probably won't say "324-th row, second column") Broken navigation when you return back to an infinitely scrolled page. What else can you think of? And what do you personally think of this approach in general. Would you use this in you projects?

  • Why (and when to) use stored procedures?

    - by mr.b
    What would be appropriate scenario when stored procedures should be used? I stumbled upon implementation where almost whole data manipulation was handled by store procedures, even simplest form of INSERT/DELETE statements were wrapped and used via SP's. So, what's the rationale for using stored procedures in general? Sorry for such a beginners question..

  • Is there an existing delegate in the .NET Framework for comparison?

    - by Neil Barnwell
    The .NET framework provides a few handy general-use delegates for common tasks, such as Predicate<T> and EventHandler<T>. Is there a built-in delegate for the equivalent of CompareTo()? The signature might be something like this: delegate int Comparison<T>(T x, T y); This is to implement sorting in such a way that I can provide a lambda expression for the actual sort routine (ListView.ListViewItemSorter, specifically), so any other approaches welcome.

  • WPF sample applications

    - by ASDFdotASPX
    Hi, Are there any WPF sample applications that showoff the 'coolness' of WPF? I'm hoping to see some examples of the UI capabilities etc., and general structure and best practices. (oh, and the install shouldn't be too elaborate hehe)
