• Is there an open source depository of custom classes for the Iphone?

  - by Chris Young

  I'm trying to learn Objective-C for xcode. I was wondering if there was an open source depository for custom classes. Things that programmers re-use. ( ie. playing card class, or peer to peer methods ) I've searched google, but so far haven't seen any type of site.

• Printing a list using reflection

  - by TFool

  public class Service{ String serviceName; //setter and getter } public class Version{ String VersionID; //setter and getter } public void test(Object list){ //it shd print the obtained list } List< Service list1; //Service is a Bean List< Version list2; //Version is a Bean test(list1); test(list2); Now the test method shd print the obtained list - (i.e) If the list is of type Service ,then serviceName should be printed using its getter. If the list type is Version versionID should be printed. Is it possible to achieve this without using Interface or abstract class?

• Operator precedence in scala

  I like scala's propose of operator precedence but in some rare case unmodified rules may be inconvenient because you have restrictions in naming your methods. Is there in scala ways to define another rules for a class/file/etc? If not would it be resolved in future?

• Is there a straightforward way to have a ThreadStatic instance member?

  - by Dan Tao

  With the ThreadStatic attribute I can have a static member of a class with one instance of the object per thread. This is really handy for achieving thread safety using types of objects that don't guarantee thread-safe instance methods (e.g., System.Random). It only works for static members, though. Is there some corresponding attribute that provides the same functionality, but for instance members? In other words, that allows me to have one instance of the object, per thread, per instance of the containing class?

• Source Code Browser

  - by James Fielding

  Hello I'm looking for a piece of relatively simple software to browse large C++ project. What I would like is something that is somewhere between a simple text editor and a full-blown IDE like Eclipse. I would like syntax highlighting, a way to see all classes/methods defined in a file, a way to find where a particular method is called from and where a variable is declared/defined. Any ideas? Thank you!

• Implementation of interface when using child class of a parent class in method of interface

  - by dotnetdev

  I don't have access to my dev environment, but when I write the below: interface IExample void Test (HtmlControl ctrl); class Example : IExample { public void Test (HtmlTextArea area) { } I get an error stating the methods in the class implementation don't match the interface - so this is not possible. HtmlTextArea is a child class of HtmlControl, is there no way this is possible? I tried with .NET 3.5, but .NET 4.0 may be different (I am interested in any solution with either framework). Thanks

• CoreData Model Objects for API

  - by theiOSguy

  I am using CoreData in my application. I want to abstract out all the CoreData related stuff as an API so that the consume can use the API instead of directly using CoreData and its generated model objects. CoreData generates the managed objects model as following @interface Person : NSManagedObject @end I want to define my API for example MyAPI and it has a function called as createPerson:(Person*)p; So the consumer of this createPerson API needs to create a Person data object (like POJO in java world) and invoke this API. But I cannot create Person object using Person *p = [Person alloc] init] because the designated initializer for this Person model created by CoreData does not allow this type of creation. So should I define corresponding user facing data object may be PersonDO and this API should take that instead to carry the data into the API implementation? Is my approach right? Any expert advise if design the API this way is a good design pattern?

• Which IDE / code editor was the first to introduce a code completion feature?

  - by Uri

  I am trying to identify the point in time where code completion (autocomplete/intellisense/whatever) was first introduced in IDEs and would appreciate any pointers. By code completion here I mean a feature within the editor that offers methods or suggestions based on the code that was already typed, and I am interested in programming language related completions (not word processor style completion).

• 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?

• Low delay audio on Android via NDK

  - by hkhauke

  Hi, it seems that this question has been asked before, I just would like to know whether there is an update in Android. I plan to write an audio application involving low delay audio I/O (appr. < 10 ms). It seems not to be possible based on the methods proposed by the SDK, hence is there - in the meantime - a way to achieve this goal using the NDK? Best regards, HK

• How to refactor logging in C#?

  - by Jader Dias

  In my services all exposed methods have: try { // the method core is written here } catch(Exception ex) { Log.Append(ex); } It's boring and ugly to repeat it over and over again. There is any way to avoid that? There is better way to keep the service working even if exceptions occurs and keep sending the exception details to the Log class?

• Which do I select - Windows Azure or Amazon EC2 - for hosting unmanaged C++ code?

  - by sharptooth

  We have a server solution written entirely in unmanaged Visual C++. It contains complicated methods for really heavy data processing. The whole thing contains millions lines of code, so rewritning it all in some other language is not an option. We could write some extra code or make isolated changes, but rewriting everything is out of the question. Now we'd like to put it on a cloud. Which platform do we choose - Amazon EC2 or Windows Azure - and why?
