  • How is "clean" testing done on the Macintosh without virtualization?

    - by Schnapple
    One of the things I've run across on Windows is when a web browser plugin or program you're developing makes an assumption that something is installed that, by default, isn't always present on Windows. A perfect example would be .NET - a whole lot of people running Windows XP have never installed any versions of .NET and so the installer needs to detect and remedy this if necessary. The way I've been testing this in Windows is to have a virtual machine with a snapshot of a clean, patched, but otherwise untouched install of XP or Vista or 7 or whatever. When I'm done testing I just discard any changes since the snapshot. Works great. I'm now developing something for the Macintosh, a platform which is very new to me, and I'm seeing that virtualization does not appear to be an option. It's explicitly forbidden in the EULA of Mac OS X, it's only allowed from Mac OS X Server, which seeing as how I'm targeting an end product is of no use to me, and the one program I see which can virtualize it - VirtualBox - only supports the server and actively nukes any discussion of running the consumer/client version of Mac OS X. And the only instructions I find anywhere on the topic seem to involve the use of "hacking" programs which is very much incompatible with the full-time gig I'm trying to do this for. So it looks like virtualization is out, but at various points I'm going to want or need to simulate what it's like to install and run this software on a "clean" Macintosh. How do people usually do this? Just buy multiple Macintoshes and use Time Machine? Am I thinking about this all wrong and everything Just Works? To be clear I'm not trying to run Mac OS X on a Windows machine. I have a Macintosh, I'm fine with virtualizing Mac OS X on Apple hardware, I'm just not seeing a route to making the non-Server version do this. I'm aware that Mac OS X Server can be virtualized but that's not what I'm going for. I'm aware that there are unsanctioned/unsupported methods of making Mac OS X run in virtualization programs like VirtualBox but for legal reasons I am not interested in those. My question is not "how can I do this?" but rather "so this thing I do on Windows seems to not be possible, generally, on the Macintosh, so what do people do to achieve what I'm going for?"

  • When should I opt for test driven development?

    - by VJ
    My question is same as the title. I have not done Test driven development yet,I have performed unit testing and I am aware of testing in general but I hear it is much advantageous to follow TDD?. So should I opt for it everytime or are there some preconditions... i just need to know some basic or important requirements when i should opt for TDD. Sorry if this question is too trivial.

    - by Joo Park
    I have a database of 50,000 records. I'm using core data to fetch records from a search. A search could return 1000 records easily. What is needed to page through these records using core data and uitableview? I would like to show 100 records at a time and have 'load more' button after viewing 100 records.

  • web service for business logic or data access layer

    - by luiscarlosch
    This post http://www.theserverside.net/tt/articles/showarticle.tss?id=Top5WSMistakes encourages me to create the web service for business logic layer but many people use it in the data access layer. I want to create a project where i want to access the same data repository from a desktop application, website and a cell phone. What would you recommend me? Is there any case it may be a good idea implement web services to both layers? thanks.

  • How can I move my Dynamic Data folder?

    - by ProfK
    I accidentally moved my Dynamic Data' folder into myImagesfolder. The project still compiles, but it's just not right. However, when I try to move it back to the root in Visual Studio, I get an error that the destination folder already exists. If I moveDynamic Data` back to the root outside of Visual Studio, the project no longer compiles because the compiler can't find any dynamic data files. My infancy with git prompted me to ask here before embarking on an unpleasant 2am quest.

  • Define "cyclic data structures"

    - by Earlz
    At the JSON site it says JSON does not support cyclic data structures, so be careful to not give cyclical structures to the JSON stringifier. What does it mean by this? Can someone give me an example of such a data structure in Javascript?

  • BDD-testing using a UI driver (e.g. Selenium for a web-application)

    - by jonathanconway
    Can BDD (Behavior Driven Design) tests be implemented using a UI driver? For example, given a web application, instead of: Writing tests for the back-end, and then more tests in Javascript for the front-end Should I: Write the tests as Selenium macros, which simulate mouse-clicks, etc in the actual browser? The advantages I see in doing it this way are: The tests are written in one language, rather than several They're focussed on the UI, which gets developers thinking outside-in They run in the real execution environment (the browser), which allows us to Test different browsers Test different servers Get insight into real-world performance Thoughts?

  • iOS Core Data migration: moving something from an entity into a file

    - by Tim Sullivan
    I have a scenario where I'm moving the contents of a blob stored in a core data entity into a file. I need a way to export that data during a migration, where I know the entity that's being converted and save the blob to a file, writing the location of that file into the converted entity's appropriate attribute. I can't seem to find a way to do this. The docs regarding the Three Stage Migration seem to indicate what can be done, but I'm not sure where to define things, or what exactly to define.

  • Saving private data

    - by rajatgoel
    Hi, Can anybody detail some approach on how to save private data in social websites like facebook, etc. They cant save all the updates and friends list in clear text format because of privacy issues. So how do they actually save it? Hashing all the data with user password so that only a valid session view it is one possibility. But I think there are some problem with this approach and there must be some better solution.

  • Investment advice data dump analysis

    - by portoalet
    For my year-end pet project, I'd like to analyze investment advices and their correlation to the stock market performance. The problem is, where do I get the dump of investment advice data (free) ? something like stackoverflow.com data dump will be nice. Or maybe it's easier to do distributed crawling and crawl the public finance webpages for investment advices? Investment advice is buy/sell advice for stocks/forex, issued by institution/investment advisor.

  • Defining your own Ord for a data type

    - by mvid
    I am attempting to make some data structures to solve a graph puzzle. I am trying to define an edge's comparison criteria, but I am not sure how. So far: data Edge = Edge (Set String) Bool How do I tell let the compiler know that I want edges to be declared equal if they have identical sets of strings, and not have equality have anything to do with the boolean value?

  • Tool to launch a script driven by modem activity

    - by Will M
    Can anyone suggest a software tool (preferably under Windows XP or later) that would launch an application or script in response to a phone call being received on a landline phone line connected to a data modem on the same PC? or, better, in response to a sequence of touch-tones being played over such a phone line. This would allow, for example, using the telephone to manipulate firewall settings so as to create another layer of security in connection with remote internet access to that computer. I seem to recall seeing tools to do this sort of thing in the days before broadband internet access, when there was more attention to various tips and tricks for the dial-up modem, but a few attempts at Google hasn't turned anything up.

  • C - How to implement Set data structure?

    - by psihodelia
    Is there any tricky way to implement a set data structure (a collection of unique values) in C? All elements in a set will be of the same type and there is a huge RAM memory. As I know, for integers it can be done really fast'N'easy using value-indexed arrays. But I'd like to have a very general Set data type. And it would be nice if a set could include itself.

  • Data files from development machine to iOS device

    - by StoneBreaker
    My app has created a bunch of data files as development has progressed through the simulator. Their location is obtained by this function: NSString *pathInDocumentDirectory(NSString *fileName) { NSArray *documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentDirectory = [documentDirectories objectAtIndex: 0]; return [documentDirectory stringByAppendingPathComponent: fileName]; } The files are now required on the device as testing of the app is moving from the simulator to actual devices. How do I transfer the data files from my current working environment to the devices?

  • How to backup data stored with Core Data - iPhone app?

    - by Alex
    I'm using sqlite for the persistent store, so could I just upload the .sqlite file to, for example, Amazon S3 as a way of providing users with the ability to backup their app data? Then for restoring just download it back and replace the existing .sqlite file in the app's folder. Does anybody see any issues with that? Has anyone done it? Any other suggestions on how to implement data backup feature?
