  • Darwin kernel architecture and OS X, 64bit on 32bit kernel, how does this work?

    - by overscore
    The OS X Lion (10.7) OS runs on mostly 64-bit binaries as reported by Activity Monitor. Given this, and the fact that my laptop runs a 32-bit version of the EFI and thus also a 32-bit kernel, how does the arch mixing work in general? Darwin Kernel Version 11.3.0: Thu Jan 12 18:48:32 PST 2012; root:xnu-1699.24.23~1/RELEASE_I386 Normally one would run 32b binaries on x86_64, but the other way around would require pushing the cpu into 64b mode, which AFAIK cannot be undone. Hope this question is clear enough..

  • Why Camera.setParameters(Camera.Parameters) does not work on Sony-Ericsson X10 and Droid?

    - by mobilekid
    Has anyone come across a strange behaviour with the Camera API when used on Sony-Ericsson X10 or Droid? For example the following code doesn't work on those devices. As a result I'm getting a lot of negative feedback on the Market translating into many cancelled orders... mParameters.set("rotation", orientation); mParameters.set("jpeg-quality", img_quality); mParameters.set("picture-size", "1024x768"); mCamera.setParameters(mParameters); Could you suggest an alternative way of achieving the same? Thanks.

  • Publishing via "File System" in Visual Studio 2010 - Doesn't work!

    - by Django Reinhardt
    Hi, this is an extremely frustrating situation. We have just upgraded to Visual Studio 2010, and very nice it is, except for when it won't do something really simple, like Publish your ASP.NET Web Application to a folder on your desktop. For some unearthly reason, what used to work flawlessly in 2008 is now generating an error: It stops Publishing, after successfully Building, saying: Error: Copying file Images\Profile\32_32.JPG to obj\x64\Release\Package\PackageTmp\Images\Prolfile\32_32.JPG failed. Could not find file 'Images\CelebrityProfileImages\32_32.JPG'. The problem is that there isn't any reference to that file in the project code (in the database, yes, but not in the code itself), and we don't want to store such images with the project (and they're not). Why (and how) has it suddenly decided that this unreferenced image (and presumably more if I get it to move past this one) is suddenly necessary to run the project? How can I stop this from happening? Thanks for any help.

What change is needed to be made?

  • jQuery - Why doesn't combining has() and gt() work in some cases?

    - by KatieK
    I wanted to select any ul which contains more than 3 lis. This code worked with the 1.2.6 jQuery library: $("ul:has(li:gt(2))") .each( function() { $(this).css("border", "solid red 1px"); }); But not 1.3.2 or 1.4.2. This code worked with the 1.4.2 jQuery library: $('ul').has('li:nth-child(3)').css('border', 'solid red 1px'); But not v1.2.6. Why does each version work with one library version, but not the other? Am I encountering some kind of bug, or am I doing something wrong? Any help understanding , or differences to be aware of between different versions of the jQuery libraries, would be much appreciated. Thanks!

  • Should properties in C# perform a lot of work?

    - by Hamish Grubijan
    When a property is read from or is assigned to, one would not expect it to perform a lot of work. When setSomeValue(...) and getSomeValue(...) methods are used instead, one should not be that surprised that something non-trivial might be going on under the hood. However, now that C# gave the world Properties, it seems silly to use getter and setter methods instead. What is your take on this? Should I mark this Q as a community wiki? Thanks.

  • focus() jQuery function doesn't work in Safari, but works fine on all other browsers?

    - by pMan
    I have a search text field and search button, when button is clicked with default text in text field, or null value, an alert pops up and sets focus back on search text field. This works very well on all major browsers but not in safari. I tried it even with out jquery, but didn't work. When the focus falls on search text field, I have another jQuery function, is that the problem. The code that sets focus on search text is: if (defaults.keyword == SEARCH_TIP || defaults.keyword == '') { alert(SEARCH_NULL); $('#store_search_keyword').focus(); return false; } The code on focus is: var search_dom = $('#store_search_keyword'); var search_text = search_dom.val(); search_dom.focus(function(){ if ($(this).val() === SEARCH_TIP) { $(this).val(''); } }); any help is appreciated, thanks..

  • Why does this static factory method involving implied generic types, work?

    - by Cheeso
    Consider public class Tuple<T1, T2> { public Tuple(T1 v1, T2 v2) { V1 = v1; V2 = v2; } public T1 V1 { get; set; } public T2 V2 { get; set; } } public static class Tuple { // MAGIC!! public static Tuple<T1, T2> New<T1, T2>(T1 v1, T2 v2) { return new Tuple<T1, T2>(v1, v2); } } Why does the part labeled "MAGIC" in the above work? It allows syntax like Tuple.New(1, "2") instead of new Tuple<int, string>(1, "2"), but ... how and why? Why do I not need Tuple.New<int,string>(1, "2") ??

  • Passing arguments to javascript file, how does it work?

    - by vietean
    From the tutorial ScriptJSONOptions of FirebugLite page, I found the below: Script JSON options It is possible to set options using a JSON object inside the linked script: <script type="text/javascript" src="https://getfirebug.com/firebug-lite.js"> { overrideConsole: false, startInNewWindow: true, startOpened: true, enableTrace: true } </script> It means that we can pass the arguments to javascript file. But I don't know how does it work? Update: My question is how to get the arguments inside the js file? P/S: I also looked into code, but I could not find the code is implemented this feature.

  • js code works for one variable(?), how to make it work for many?

    - by jerry87
    I have working code of js, it shows different div for selected option. <html> <head> <script src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript"> $(document).ready(function(){ $('#box1').hide(); $('#box2').hide(); $('#box3').hide(); $("#thechoices").change(function(){ $("#" + this.value).show().siblings().hide(); }); $("#thechoices").change(); }); </script> </head> <body> <select id="thechoices"> <option value="box1">Box 1</option> <option value="box2">Box 2</option> <option value="box3">Box 3</option> </select> <!-- the DIVs --> <div id="boxes"> <div id="box1"><p>Box 1 stuff...</p></div> <div id="box2"><p>Box 2 stuff...</p></div> <div id="box3"><p>Box 3 stuff...</p></div> </div> </body> </html> Please, I have no js experience, so I don't know how to make it work several times on one page for many "thechoices". Something like copy paste but more suitable than this: <script type="text/javascript"> $(document).ready(function(){ $('#box1').hide(); $('#box2').hide(); $('#box3').hide(); $('#box4').hide(); $('#box5').hide(); $('#box6').hide(); $("#thechoices").change(function(){ $("#" + this.value).show().siblings().hide(); }); $("#thechoices2").change(function(){ $("#" + this.value).show().siblings().hide(); }); $("#thechoices").change(); }); $("#thechoices2").change(); }); </script> </head> <body> <select id="thechoices"> <option value="box1">Box 1</option> <option value="box2">Box 2</option> <option value="box3">Box 3</option> </select> <!-- the DIVs --> <div id="boxes"> <div id="box1"><p>Box 1 stuff...</p></div> <div id="box2"><p>Box 2 stuff...</p></div> <div id="box3"><p>Box 3 stuff...</p></div> </div> <select id="thechoices2"> <option value="box4">1</option> <option value="box5">2</option> <option value="box6">3</option> </select> <!-- the DIVs --> <div id="boxes"> <div id="box4"><p>1 stuff...</p></div> <div id="box5"><p>2 stuff...</p></div> <div id="box6"><p>3 stuff...</p></div> </div> I know you can help me, it seems to be simple but I can't handle with this. How can I change my second code to work in the same way but not only for two selectors. I need it for many. Don't want to copy paste the same section like in my second code.

  • How to go about finding ad-hoc development work on the web?

    - by DaveDev
    I'm wondering if its possible to find supplementary development work on line? I have some time available to me in the evenings and I thought it might be good to use it productively. It'd be great if there was a site that I could apply to do some ad-hoc coding for anyone who needs it. Something like 'I need a class that does XY & Z', and I could do that. Is there anything like this out there? Can somebody supply me with some info? Thanks

    - by Nastase Ion
    Hi everyone! I need to convert a custom object to a different object. How can I do that? I know that typecasting doesn't work (the only thing is does is "shuts the compiler warnings off", but nothing more). Here is a sample code: MyType* obj1; MyOtherType* obj2; obj1 = [MyType initWithData: 1]; obj2 = (MyOtherType*) obj1; if ([obj2 isMemberOfClass: [MyOtherType class]]) { NSLog(@"OK"); } else if ([obj2 isMemberOfClass: [MyType class]]) { NSLog(@"Nope"); } The result is: Nope What can I do??

  • Drupal: $form['#redirect'] = FALSE; doesn't work.

    - by Patrick
    hi, I've tried to change the redirection when I submit my edit-node form, by addming the following line to my template.php file, in my theme $form['#redirect'] = FALSE; I'm sure the template.php file works well because I have other lines in which I change, for example, the weights of some elements. But the redirection doesn't work. I've also tried $form['#redirect'] = 'anotherPage'; without success. What am I doing wrong ? I'm following the Drupal APIs, about forms: http://api.drupal.org/api/drupal/developer--topics--forms_api_reference.html/6#redirect thanks

  • .Htaccess & Wildcard Subdomains — Can't get other variables to work!

    - by Justin Scheetz
    It would be absolutely awesome if someone could help me out here. I have a domain, let's call it "example.com". I have wildcard subdomains setup and working great. The only problem is I can't get htaccess to see anything else like subdomain.example.com/profile/some_name/some_id_number/. In fact, I can type any garbage after the domain and it will still just show me the home screen. Here's what's in my htaccess file now: Options +FollowSymLinks Options +Indexes Options -Multiviews RewriteEngine On RewriteCond %{REQUEST_URI} !^/app/index.php RewriteCond %{HTTP_HOST} !^www\.example\.com RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com RewriteRule (.*) /app/index.php?user%1 [L] I can see why that wouldn't work yet, but I wanted to add something similar to the following: RewriteRule ^profile/([^/]+)/([^/]+) /app/index.php?page=profile&username=$1&user_id=$2 [nc] But it's not working at all. The server doesn't even really show signs that it's even seeing it there. Any ideas?

  • How to schedule heavy work for later display for Listviews?

    - by Pentium10
    I have a listview with 200 items. I use a custom view for each row. There is a code that takes some time to calculate, and because of this the list hangs out on scrolling and loads in slow (2-3sec). I have subclassed SimpleCursorAdapter, and using Filterable and SectionIndexer. I have in mind to show initially the name of the record, and put in a thread the calculation, and will show up later when it's done. How do I push back some work, and later update the listview to include the calculated data? This should show up on fly without user interaction.

  • Does the API call ExitProcess() work OK in VB6 if you follow the MS caveats?

    - by Clay Nichols
    Microsoft indicates that VB6 doesn't support ExitProcess (to exit and return a value). However, it indicates that this call can fail under certain circumstances (if a thread hasn't been completed, etc.) so I'm wondering whether this call will work OK (consistently :-) as long as you obey the caveats in the article. I could go a step further and call ExitProcess() from the Sub Main or Form which stared the app. Update: after some more reading (I really did research this a bit before asking ) I found a suggestion to use the TerminateProcess API instead. I'm investigating that option. Any thoughts?

  • How can we make agile enjoyable for developers that like to personally, independently own large chunks from start to finish

    - by Kris
    We’re roughly midway through our transition from waterfall to agile using scrum; we’ve changed from large teams in technology/discipline silos to smaller cross-functional teams. As expected, the change to agile doesn’t suit everyone. There are a handful of developers that are having a difficult time adjusting to agile. I really want to keep them engaged and challenged, and ultimately enjoying coming to work each day. These are smart, happy, motivated people that I respect on both a personal and a professional level. The basic issue is this: Some developers are primarily motivated by the joy of taking a piece of difficult work, thinking through a design, thinking through potential issues, then solving the problem piece by piece, with only minimal interaction with others, over an extended period of time. They generally complete work to a high level of quality and in a timely way; their work is maintainable and fits with the overall architecture. Transitioning to a cross-functional team that values interaction and shared responsibility for work, and delivery of working functionality within shorter intervals, the teams evolve such that the entire team knocks that difficult problem over. Many people find this to be a positive change; someone that loves to take a problem and own it independently from start to finish loses the opportunity for work like that. This is not an issue with people being open to change. Certainly we’ve seen a few people that don’t like change, but in the cases I’m concerned about, the individuals are good performers, genuinely open to change, they make an effort, they see how the rest of the team is changing and they want to fit in. It’s not a case of someone being difficult or obstructionist, or wanting to hoard the juiciest work. They just don’t find joy in work like they used to. I’m sure we can’t be the only place that hasn’t bumped up on this. How have others approached this? If you’re a developer that is motivated by personally owning a big chunk of work from end to end, and you’ve adjusted to a different way of working, what did it for you?

  • WPF RelativeSource FindAncestor doesn't work outside of the Control.Resources context?

    - by sker
    I have this VisualBrush resource I took from some site and I apply it with triggers to a TextBox. <VisualBrush x:Key="HelpBrush" TileMode="None" Opacity="0.4" Stretch="None" AlignmentX="Left"> <VisualBrush.Visual> <TextBlock FontStyle="Italic" Text="{Binding Path=Tag, RelativeSource={RelativeSource AncestorType={x:Type Control}, AncestorLevel=1}}"/> </VisualBrush.Visual> </VisualBrush> <Style x:Key="DefaultText" TargetType="TextBox"> <Style.Triggers> <Trigger Property="Text" Value="{x:Null}"> <Setter Property="Background" Value="{StaticResource HelpBrush}"/> </Trigger> <Trigger Property="Text" Value=""> <Setter Property="Background" Value="{StaticResource HelpBrush}"/> </Trigger> </Style.Triggers> </Style> If I place both the VisualBrush and the Style inside the TextBox.Resources tag in XAML, it works fine. But if I take it out and place it in the Window.Resources or a merged dictionary, it stops working. The problem is the Binding, it doesn't find the ancestor TextBox for some reason. I already tried removing AncestorLevel and using AncestorType={x:Type TextBox} - it doesn't work. Any ideas?

  • Why would Basic Auth not work with my WCF client to Java SOAP Web Service?

    - by orj
    I have a Java based web service that requires basic authentication to communicate with it. If I type the WSDL url into my browser I'm prompted for Basic Auth. Which I can get by entering the correct credentials. However using my WCF client doesn't work. I construct my WCF client like this: var binding = new BasicHttpBinding { MaxReceivedMessageSize = 2048 * 10240, Security = { Mode = BasicHttpSecurityMode.TransportCredentialOnly, Transport = { ClientCredentialType = HttpClientCredentialType.Basic, Realm = "MYREALM", ProxyCredentialType = HttpProxyCredentialType.None }, Message = { ClientCredentialType = BasicHttpMessageCredentialType.UserName, AlgorithmSuite = SecurityAlgorithmSuite.Default } } }; var client = new WebServiceClient(binding, endpoint); client.ClientCredentials.UserName.UserName = username; client.ClientCredentials.UserName.Password = password; client.DoWebServiceMethod(); I get the following exception. System.Net.WebException: The remote server returned an error: (401) Unauthorized. at System.Net.HttpWebRequest.GetResponse() at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout) System.ServiceModel.Security.MessageSecurityException: The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was 'Basic realm="MYREALM"'. From what I can tell I'm doing things right. Where am I going wrong?
