• What's a good free tool for investigating unintentional object retention in Java?

  - by Steve Emmerson

  My multithreaded Java program crashes because it runs out of heap space and I don't think it should. Assuming the culprit is unintentional object retention, what's a good free tool to investigate what objects are being unintentionally retained? My IDE is Eclipse.

• c++: see compiled object layout

  - by horsthahn

  Hi, is there a way - much like the way i can see the result of preprocessing when using 'gcc -E' - to see what my objects look like once the compiler compiled them into object files? I am not too good in reading assembler, so an advice to get the results as text would be nice .. or at least a little 'howto read the constructor intructions' or 'howto find the constructor' ... I am talking about gcc/g++, but a solution including msvc would be fine. Thanks!

• How to check whether an object has a specific method or not

  - by Ghommey

  Hey, I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell whether $myObject has a method called helloWorld or not?

• Why does this crash: stringByAppendingFormat

  - by Emil

  Hey. My code crashes at this function (at the stringByAppendingFormat: with error objc_msgSend() selector name: stringByAppendingFormat). This is that line: // imagesPath = ...iPhone Simulator/4.0/Applications/NUMBERS/Documents/images UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingFormat:@"/%d.png", [[self.postsArrayID objectAtIndex:row] intValue]]]; Could it have something to do with the retaining of objects? Thanks :)

• Are there java libraries to do a word-based diff?

  - by Mycol

  I have two pieces of text. I would like to make a word-based diff between them (like whe unix utility wdiff does) but with more information in the output (I mean, the character's posizion where the added/delited word starts). I need to do this in Java, so a simple output of the differences (like wdiff) doesn't suite for me: I would like to manipulate objects representing differences.

• Javascript serialization

  - by John

  Have I any chance to serialize meta (any format, so I can store it in DB)? var obj1 = {}; var obj2 = {}; obj1.link = obj2; obj2.link = obj1; var meta = [obj1, obj2]; As I understand the problem is that JSON serialize object`s links to objects.

• A nuts and bolts reference to C# performance and memory use

  - by phil

  I wonder if anyone could point me in the direction where I can read about the nuts and bolts of C#. What I'm interested in learning are method call costs, what it costs to create objects and such. My aim of learning this is to get a better understanding of how increase the performance of an application and get a better understanding of how the C# language works. The reference should preferable be a book, a book that I can read cover to cover.

• Using Predicate of a class to Search Generic list - Faster than looping?

  - by Srikanth

  Lets say we have a generic list of Class1, typically having ~100 objects for a given session. I would like to see if the list has a particular object. ASP.NET 2.0 allows me to do this: Dim objResult as Class1 = objList.Find(objSearch) How does this approach rate when compared to a traditional For loop, looking at a performance perspective? How would this vary with increase or decrease in length of the list?

• How can I limit other (administrator) users access to my profile?

  - by kojo

  Hi, We in our club have a computer with Windows 7 Professional that every club member may use. And everyone has their own separate account. Those accounts have to have administrator priveleges since I want everyone to be able to install any software and use any feature they want. However, there is a single thing that they shouldn't be allowed to do - that is, look into another users' profiles. Now when anyone goes to 'c:\Users(Any User Name)' a little prompt appears that this folder is secured and whether you really want to look inside. Simply clickinh 'ok' give you access to any profile. I tried disabling taking ownership for Administrators group in Group Policies but that had no effect. How can I effectively prohibit administrators looking into each others' profiles and documents?

• Is it better to store an NSArray of NSManagedObjects or NSManagedObjectIDs?

  - by Kevin

  In my application I need to keep track of a list of objects that are being displayed. Right now I have an NSArray with all of the NSManagedObjects. Would I be better off to store the ObjectIDs and then only request the object when I need it? I am mainly concerned about memory at this point.

• What's the term for an isolated set of references?

  I know I learnt this on the SCJP syllabus, but it escapes me. What's the term for a set of objects that refer to each other but are no longer accessible from your program (and are thus eligible for garbage collection)?

• Does Flex/Actionsctipt/Flash implements a mechanism for reusing Sprites?

  - by php html

  I'm creating a game and I create sprites(enemies). I keep creating and destroying sprites. Flash/Flex has a garbage collector which handles the destruction of unused resources. Should I create an object pool to reuse them, or should I leave flash/flex to handle the creation/destruction of objects? Which option is better from the performance point of view?

• best scala idiom for find & return

  - by IttayD

  This is something I encounter frequently, but I don't know the elegant way of doing. I have a collection of Foo objects. Foo has a method bar() that may return null or a Bar object. I want to scan the collection, calling each object's bar() method and stop on the first one returning an actual reference and return that reference from the scan. Obviously: foos.find(_.bar != null).bar does the trick, but calls #bar twice.

• javascript: use getElementsByName for 'this'?

  - by stelmate

  I need to get some children elements and loop over them using inline javascript for a onmouseover event. When I try to use this.getElementsByName I'm getting an error that the object does not support this property. I was under the impression that getElementsByName work for element objects which I thought 'this' would be considered. Anyone have any other ideas on how I can achieve this?

• Is it the best practice to extract an interface for every class?

  - by the_drow

  I have seen code where every class has an interface that it implements. Sometimes there is no common interface for them all. They are just there and they are used instead of concreate objects. They do not offer a generic interface for two classes and are specific to the domain of the problem that the class solves. Is there any reason to do that?
