  • does copyWithZone on an NSArray call copyWithZone on its elements too?

    - by malik
    Hi, here's the scenario, I have this array of Person objects. copyWithZone is implemented on Person and works as expected. I have an array of Person objects, however when I create a copy of the array and modify things in original array (change attributes of a Person) it chances the copy as well. So my best guess is that when I call copyWithZone on NSArray, it does not call it on its elements. Please confirm.

  • Where to go from PHP?

    - by dabito
    I'm a seasoned PHP programmer and I really like the way it works and find it very fun to work with (performance could be improved and some functions renamed, but nothing too serious). However, I took a java seminar and now Im very interested in using GWT for upcomming projects, although I think the learning curve can be steep. Should I really go through with this change (PHP JAVA)? Where to begin?

  • Rolling back a transaction in a Grails Service

    - by UltraVi01
    I have been updating all my services to be transactional by using Grail's ability to rollback when a RuntimeException is thrown in the service. I have, in most cases, doing this: def domain = new Domain(field: field) if (!domain.save()) { throw new RuntimeException() } Anyways, I wanted to verify that this indeed will rollback the transaction... it got me thinking as to whether at this point it's already been committed.. Also, if not, would setting flush:true change that? I am not very familiar with how Spring/Hibernate does all of this :)

  • Named parameters lead to inferior readability?

    - by Thomas Jung
    With named parameters like def f(x : Int = 1, y : Int = 2) = x * y your parameter names become part of the interface f(x=3) Now if you want to change the parameter names locally, you are forced to perserve the public name of the parameter: def f(x : Int = 1, y : Int = 2) = { val (a,b) = (x,y) a * b } If this a real problem? Is there a syntax to support this directly? Who do other languages handle this?

  • Are regexes really maintainable?

    - by Rich Bradshaw
    Any code I've seen that uses Regexes tends to use them as a black box: Put in string Magic Regex Get out string This doesn't seem a particularly good idea to use in production code, as even a small change can often result in a completely different regex. Apart from cases where the standard is permanent and unchanging, are regexes the way to do things, or is it better to try different methods?

  • Disable email when modifying several bugs at once in bugzilla

    - by Jay Paroline
    Where I work, we use Bugzilla extensively for bug and feature tracking. We take advantage of the built in milestones to help us manage our timelines better, but sometimes priorities shift and milestones need to be rearranged. During this time we use the "change several bugs at once" feature to move them around, but the result is a ton of bugspam for everyone involved (except the person actually doing the changing, of course). Is there any way to easily turn off emails if many bugs are being changed at once?

  • Issues in Ajax based applications

    - by Sinuhe
    I'm very interested in developing Ajax based applications. This is, loading almost all of the content of the application via XMLHttpRequest, instead of only some combos and widgets. But if I try to do this form scratch, soon I find some problems without an easy solution. I wonder if there is some framework (both client and server side) to deal with this issues. As far as I know, there isn't (but I've searched mainly in Java world). So I am seriously thinking of doing my own framework, at least for my projects. Therefore, in this question I ask for several things. First, the possible problems of an ajax based development. Then, I'm looking for some framework or utility in order to deal with them. Finally, if there is no framework available, what features must it have. Here are the issues I thought: 1 - JavaScript must be enabled. Security paranoia isn't the only problem: a lot of mobile devices couldn't use the application, too. 2 - Sometimes you need to update more than one DIV (e.g. main content, menu and breadcrumbs). 3 - Unknown response type: when you make an Ajax call, you set the callback function too, usually specifying if expected response is a javascript object or in which DIV put the result. But this fails when you get another type of response: for example when the session has expired and the user must log in again. 4 - Browser's refresh, back and forward buttons can be a real pain. User will expect different behaviors depending on the situation. 5 - When search engines indexes a site, only follow links. Thus, content load by Ajax won't "exist" for who doesn't know about it yet. 6 - Users can ask for open a link in a different window/tab. 7 - Address bar doesn't show the "real" page you are in. So, you can't copy the location and send it to a friend or bookmark the page. 8 - If you want to monetize the site, you can put some advertisings. As you don't refresh entire page and you want to change the ad after some time, you have to refresh only the DIV where the ad is. But this can violate the Terms and Conditions of your ad service. In fact, it can go against AdSense TOS. 9 - When you refresh an entire page, all JavaScript gets "cleaned". But in Ajax calls, all JavaScript objects will remain. 10 - You can't easily change your CSS properties.

    I need to have a file for database configuration outside of EAR file of my EJB application.

  • How do you override ProgramFilesFolder in an msi?

    - by Mark
    I have an msi file that I am trying to install in a place other than C:\Program Files. The directory table shows that ProgramFilesFolder is used as the default install directory. From reading this blog post I understand that ProgramFilesFolder is a standard directory so passing TARGETDIR as a property to the installer will not change the install location even through the directory table has it as the parent of ProgramFilesFolder. How can I override the install location? I am a total novice in this area.

  • domain modeling naming problem

    - by cherouvim
    Hello There are some simple entities in an application (e.g containing only id and title) which rarely change and are being referenced by the more complex entities of the application. These are usually entities such as Country, City, Language etc. How are these called? I've used the following names for those in the past but I'm not sure which is the best way to call them: reference data lookup values dictionaries thanks

    - by Encore PTL
    Is there a way to prevent the zoom_change event from being triggered if it occurs due to fitBounds() ? I am having an issue where I need to do a search on the server from client when there is a zoom change to map but every time I call fitBounds() it causes zoom_change to trigger which causes the client to do another search on the server. I am only interested in zoom_change done by users and not programmatically using fitBounds.

  • Access Creates new file every time I Compact & Repair

    - by NickSentowski
    It didn't always do this, but ever since I split my database and made the front-end an ACCDE file, any time I try to compact and repair either file, a new file called "Database 1" is generated and my original file size doesn't change. Is this normal? My ACCDB is roughly 20MB, and my ACCDE is just over 1M after being used the first time. Before opening, the ACCDE was only 600k (I have lots of forms and queries, and regularly store PDF attachments.
