  • can anyone have ADC Student Membership ?

Currently apple replaces the ADC with mac and that program wont allow for free ticket. Can anyone who wont go to WWDC but do have the ADC student membership, barrow their ticket :), I am out of funds actually. Thanks,

  • How to use Obj-C classes in MacRuby

    - by beno1604
    I am trying to use an external Obj-C class in my MacRuby project, but I can't figure out how to import it. Specifically, I want to use ObjectiveResource inside a MacRuby 0.5 project (since ActiveResource doesn't work - yet). I have gotten as far as the 'framework' command in MacRuby, but it only seems to apply to actual frameworks. Questions: where should I install the objective-resource directory? how do I pull these classes inside my ruby code? Thanks for any help!

  • Why has Javascript been (mostly) only a browser-side technology for more than 10 years?

    - by Gabriel Cuvillier
    Recently there is a lot of projects that pushes Javascript into other directions: as a general purpose scripting language (GLUEScript, Rhino), as an extension language (QTScript, Adobe Reader, OO Macros), Widgets (Yahoo Widgets, MS Gadgets, Dashboard), and even server-side JS & web frameworks (CommonJS, Helma, Phobos, V8cgi), which seems obvious since it is already a language widely used for web development. But wait, everything is so new and nothing is really mature. However JS is around for almost 15 years, being as powerfull as any other scripting languages, being standardised by the ECMA, and being a mandatory technology for web development. Why did it take so much time to gain acceptance into other domains than web browsers?

  • DurandalJS vs AngularJS?

    - by Zach
    I'm looking for a JS framework to build an SPA and found DurandalJS and AngularJS. Can anyone compare these two frameworks? I did find many articles that compares AngularJS and KnockoutJS, and they say AngularJS is more than data binding, so I think DurandalJS may be the one to compare. I did a little research on AngularJS, it is good but one thing is bad: the $ prefix does not work when minified, although there is an ugly workaround. And someone said Twitter Bootstrap does not work well with it (I didn't check). For DurandalJS, I still cannot find the samples (http://durandaljs.com/documentation/Understanding-the-Samples/), so it's hard to say. PS: are they working well with TypeScript? Best regards, Zach

  • Automate Testing on future only items business rules

    - by Titan
    I currently have a business object with a validation business rule, which is it can only be created for the future, tomorrow onwards, and I cannot create new items for today. I have a process, which runs the non-future business objects through some steps.. Because I have to set things up today, and test tomorrow, and when it fails, I can only create a new object tomorrow and test the following day. Are there any easy ways to automate this process in any testing frameworks? I think our testers are using the visual studio 2010 test manager. How do you guys manage situations like this? Cheers

  • Is there an equivalent to Java's ClassFileTransformer in .NET? (a way to replace a class)

    - by Alix
    I've been searching for this for quite a while with no luck so far. Is there an equivalent to Java's ClassFileTransformer in .NET? Basically, I want to create a class CustomClassFileTransformer (which in Java would implement the interface ClassFileTransformer) that gets called whenever a class is loaded, and is allowed to tweak it and replace it with the tweaked version. I know there are frameworks that do similar things, but I was looking for something more straightforward, like implementing my own ClassFileTransformer. Is it possible? EDIT #1. More details about why I need this: Basically, I have a C# application and I need to monitor the instructions it wants to run in order to detect read or write operations to fields (operations Ldfld and Stfld) and insert some instructions before the read/write takes place. I know how to do this (except for the part where I need to be invoked to replace the class): for every method whose code I want to monitor, I must: Get the method's MethodBody using MethodBase.GetMethodBody() Transform it to byte array with MethodBody.GetILAsByteArray(). The byte[] it returns contains the bytecode. Analyse the bytecode as explained here, possibly inserting new instructions or deleting/modifying existing ones by changing the contents of the array. Create a new method and use the new bytecode to create its body, with MethodBuilder.CreateMethodBody(byte[] il, int count), where il is the array with the bytecode. I put all these tweaked methods in a new class and use the new class to replace the one that was originally going to be loaded. An alternative to replacing classes would be somehow getting notified whenever a method is invoked. Then I'd replace the call to that method with a call to my own tweaked method, which I would tweak only the first time is invoked and then I'd put it in a dictionary for future uses, to reduce overhead (for future calls I'll just look up the method and invoke it; I won't need to analyse the bytecode again). I'm currently investigating ways to do this and LinFu looks pretty interesting, but if there was something like a ClassFileTransformer it would be much simpler: I just rewrite the class, replace it, and let the code run without monitoring anything. An additional note: the classes may be sealed. I want to be able to replace any kind of class, I cannot impose restrictions on their attributes. EDIT #2. Why I need to do this at runtime. I need to monitor everything that is going on so that I can detect every access to data. This applies to the code of library classes as well. However, I cannot know in advance which classes are going to be used, and even if I knew every possible class that may get loaded it would be a huge performance hit to tweak all of them instead of waiting to see whether they actually get invoked or not. POSSIBLE (BUT PRETTY HARDCORE) SOLUTION. In case anyone is interested (and I see the question has been faved, so I guess someone is), this is what I'm looking at right now. Basically I'd have to implement the profiling API and I'll register for the events that I'm interested in, in my case whenever a JIT compilation starts. An extract of the blogpost: In your ICorProfilerCallback2::ModuleLoadFinished callback, you call ICorProfilerInfo2::GetModuleMetadata to get a pointer to a metadata interface on that module. QI for the metadata interface you want. Search MSDN for "IMetaDataImport", and grope through the table of contents to find topics on the metadata interfaces. Once you're in metadata-land, you have access to all the types in the module, including their fields and function prototypes. You may need to parse metadata signatures and this signature parser may be of use to you. In your ICorProfilerCallback2::JITCompilationStarted callback, you may use ICorProfilerInfo2::GetILFunctionBody to inspect the original IL, and ICorProfilerInfo2::GetILFunctionBodyAllocator and then ICorProfilerInfo2::SetILFunctionBody to replace that IL with your own. The great news: I get notified when a JIT compilation starts and I can replace the bytecode right there, without having to worry about replacing the class, etc. The not-so-great news: you cannot invoke managed code from the API's callback methods, which makes sense but means I'm on my own parsing the IL code, etc, as opposed to be able to use Cecil, which would've been a breeze. I don't think there's a simpler way to do this without using AOP frameworks (such as PostSharp). If anyone has any other idea please let me know. I'm not marking the question as answered yet.

  • detect focus on browser address bar?

    - by jedierikb
    Is there a way to detect when focus has been put onto the address-bar or the browser-search-bar? I ask because I am trying to keep focus on one element in my document, but adding a blur() listener to that element works too well in safari mac -- you can't put focus on the address-bar!

  • How come string.maketrans does not work in Python 3.1?

Could anyone please help post a working code for Python 3.1 if it's possible?

  • Circular dependencies in StructureMap - can they be broken with property injection?

    - by Andy
    Hi, I've got the simplest kind of circular dependency in structuremap - class A relies on class B in its constructor, and class B relies on class A in its constructor. To break the dependency, I made class B take class A as a property, rather than a constructor argument, but structuremap still complains. I've seen circular dependencies broken using this method in other DI frameworks - is this a problem with Structuremap or am I doing something wrong? Edit: I should mention that class B's property is an array of class A instances, wired up like this: x.For<IB>().Singleton().Use<B>().Setter(y => y.ArrayOfA).IsTheDefault();

  • Free-as-in-beer binary file format inspector

    - by fbrereto
    I am looking for a utility that gives me the ability to specify a binary file format and then interpret a file of bytes according to that format. (Something along the lines of the 010 Editor, but infinitely more cost-effective). Something that runs on Mac OS X would be preferred, but I'm interested to see what all is out there in general (while more of a hassle I'd be willing to run a tool on Windows if it were superior.) What's your preference?

  • Why is there no assertError() function in FlexUnit?

    - by lorennorman
    It seems that most XUnit testing frameworks provide assertions for the times when you want to assert that a given operation will thrown an exception (or an Error in AS3 parlance.) Is there some "standard" way of doing this that I am overlooking, which would explain the absence of an assertError() assertion included with FlexUnit? I know HOW to implement such a thing, and I will probably add it to my FlexUnit (go open source!), but it seems like such a glaring omission that I'm left wondering if I'm just doing it wrong. Anyone have thoughts on this?

    Alright, this is a very simple question. I just installed Tomcat 6 on my Mac to play around with it, and every tutorial I look at says the first thing to do to create a new web application is to add a line to the server.xml file with defines a new Context. Fair enough. However, my question is, I don't see a line in there for the example web applications, so how do those work?

  • Strategy for Offline/Online data synchronization

    - by Adi
    My requirement is I have server J2EE web application and client J2EE web application. Sometimes client can go offline. When client comes online he should be able to synchronize changes to and fro. Also I should be able to control which rows/tables need to be synchronized based on some filters/rules. Is there any existing Java frameworks for doing it? If I need to implement on my own, what are the different strategies that you can suggest? One solution in my mind is maintaining sql logs and executing same statements at other side during synchronization. Do you see any problems with this strategy?
