  • How to debug wifi connection?

    - by mmb
    I am using Ubuntu's Network Manager to connect to a local wifi router. My problem is, that it often disconnects without any visible reason (router is on, internet connection seems to be working, wifi diodes are blinking). I mostly have to disable wifi from Network Manager, enable it again to get wifi connecting again. Plus I am often experiencing Network Manager trying to connect to my wifi, trying several times but then giving up. I even tried an external usb-wifi card, but with the very same results. My question is: How can I debug this? Which logs should I read to see what is really happening when all of these errors occur - so I can post them here and see how to proceed?

  • Is there a prohibition against scaling collision shapes at runtime?

    - by Almo
    So, I have a StaticMeshComponent attached to an Actor: Begin Object Class=StaticMeshComponent Name=StaticMeshComponentObject StaticMesh=StaticMesh'QF_Art_Powers.Mesh.GP_ForcePush' CollideActors=true BlockActors=false //Scale3D=(X=5, Y=1.5, Z=3) // ALMODEBUG End Object CollisionComponent=StaticMeshComponentObject Components.Add(StaticMeshComponentObject) Ordinarily, the actor gets spawned, anything touching it gets bumped, and the actor despawns itself. If I set the Scale3D as a default property, everything works as I expect. But I want to scale it at runtime, like this: function SetImpulseComponentTemplate(QuadForceBoxImpulseComponent Value) { Local Vector ScaleVec; ScaleVec.X = Value.Length; ScaleVec.Y = Value.Width; ScaleVec.Z = Value.Height; CollisionComponent.SetScale3D(ScaleVec); } When I do this, the thing only collides as if it were not scaled. If I leave the actor spawned so I can see it, it is scaled. If I also "show collision", the collision displays correctly as well. Is there a prohibition against scaling collision shapes at runtime?

  • Wrong/corrupted icon in dash

    - by Swarnendu Biswas
    I am facing a problem with the dash not showing proper/actual icons for certain applications such as Google Chrome and Mozilla Daily Mail. Instead of getting the standard icons for these applications, I get to see a default icon for all the applications. I have added a snapshot to show the problem. The icons that are shown in the launcher once launched or in the /usr/share/applications directory are proper. I have tried rebuilding the icon cache, but that did not help. I have also tried switching to other icons themes. This issue does not appear with Gnome Shell or KDE. I have also tried deleting ~/.local/share/applications/menu-xdg, there was none in the first place. I am using Ubuntu 12.10. Any suggestions would be appreciated.

  • Ubuntu 14.04 upgrade succeeded partially - I would like to use a different mirror; how can I do that?

    - by user290648
    When I wanted to upgrade from Ubuntu 13.10 to 14.04 the update manager told me that there was an unresolvable problem with calculating the upgrade. In order to see more details I performed the following on the command line: apt-get update apt-get upgrade apt-get dist-upgrade apt-get install update-manager-core do-release-upgrade Now do-release-upgrade tells me that no newer version is available but the "about" box in the main menu tells me I am still on 13.10. I think the latter is right, as for instance in the "system settings" there is no way to select local menus, which is present in 14.04 (I tried with a DVD, and there it is). Maybe the problem is related to the fact that "apt-get update" cannot get two resources called "saucy/InRelease" and "saucy/main/binary-i386/Packages" from the mirror (mirror.informatik.uni-mannheim.de; 404 not found). I would like to use a different mirror; how can I do that? Any help appreciated, thanks in advance.

  • Where is the source of domain search? [closed]

    - by All
    There are several websites providing service of searching for free domains (websites, not registrars). I wonder where is the source of these searches? This search cannot be based on local database, as it needs live data (of available domains). The only possible way (to me) is to fetch every query from the original NIC (e.g. nic.com), but I was unable to find an API for this service. How to find a source to write a script for domain searching?

  • Pitfalls of using a WYSIWYG editor? [closed]

    - by user50849
    I'm interested in reasons for disallowing content editors on medium to large sites, from using various forms of WYSIWYG editors. A common problematic scenario I can think of is that with the use of a WYSIWYG, an editor uploads an image "somewhere" to the file-system, inserts it directly into the text, and publishes the article. Shortly afterwards, someone wants to pull out "The last 10 uploaded images", and display them on the frontpage. Good luck parsing all the content. Taking a look around at some large international online magazines, such as http://www.time.com/, and some local ones, I see that the editors seem to produce articles that are almost only consisting of raw text. Images are usually at the top of the article, and otherwise the most complex content are usually links. What are some common reasons for refusing editors access to WYSIWYG tools?

  • NDC 2010 Day 0

    Today I arrived in Oslo, Norway with a colleague for Norwegian Developer Conference. This is my first visit and the agenda looks very good.

Day [...]...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • Initialize array in O(1) -- how is this trick called?

    - by user946850
    There is this pattern that trades performance of array access against the need to iterate it when clearing it. You keep a generation counter with each entry, and also a global generation counter. The "clear" operation increases the generation counter. On each access, you compare local vs. global generation counters; if they differ, the array has been reset. This has come up in StackOverflow recently, but I don't remember if this trick has an official name. Does it? One use case is Dijkstra's algorithm if only a tiny subset of the nodes has to be relaxed, and if this has to be done repeatedly.

  • Game Object Design

    - by oisin
    I'm having a problem with the way I designed my first simple game in C++. I have GameObject (abstract class) and ObjectA which inherits the update() and draw() methods from GameObject. My main loop contains a linked list of GameObject*, and while that list is not empty it cycles through it, calling update on each one. Up until this point, I thought the design was standard(?) and would work. However, when I call update on ObjectA() I run into two problems: ObjectA can die which messes up the list, which in turn throws off the loop in main. ObjectA can spawn more ObjectA's but these are local scope and the update() goes out of scope, creating problems in main's list of GameObjects. I think my design if alright, but I'm having such problems with segmentation faults that there must be something seriously wrong with at least one part of my implementation. If anyone could point out any serious mistakes or simple examples of this being done (or even alternative designs) then I would greatly appreciate it!

  • php cms withouth database

    - by user1791795
    A friend of mine asked me for a easy website for him. As it was just 3 subpages, no database need or anything, I've done it quite fast with plain PHP, HTML, JS and CSS. But then another and another friend showed up. They only wanted arrange differently they navigation, some different picutures etc. So I though, is there any kind of CMS, that allows build small business website (barbershop, local groceries shop), with small list of subpages, yet allowing us to arrange look'n'feel. There's no need for the databas as content won't change, or can be stored in simple textfiles for example. Things like WordPress might be simple overkill Does anyone know such cms?

  • Is it possible to use the Raring install image as a package repo (like the old alternate CD)?

    - by jamadagni
    I use Kubuntu and recently upgraded to Raring directly from Precise. Until Precise, I always installed the OS using the alternate CD and not the desktop CD, because I could later on mount the image and use it as an offline package repo. For instance if I remove a package installed by the default installer and later I want to install it again, I can just install it from the ISO without needing to download it again. However, since Quantal the alternate CD no longer exists, so I am not sure how to set up the installed image as a local repo. I mean, doing find . -name "*.deb" inside the ISO tree after loopmounting it only shows a few packages like libc6 gcc and such and not the full set of packages that are actually installed -- I presume they are included in pre-installed form inside casper/filesystem.squashfs. Given this situation, is it or is it not possible to use the Raring install images as offline repos? If yes, how? Thank you!

  • Access/update Telerik RadGrid item values in code-behind before ODS event handler

    - by Brent
    Hi there, I need to update some of the values of the item being edited in my code-behind based on some values in a custom Edit Form on our Rad Grid. Can I access the item (and update some values) from one of the Grid's event handlers? Currently I'm storing the values in temporary variables and then injecting the new values in the ObjectDataSource's Inserting/Updating event handlers, but it would be much nicer if I could do it all in one spot. (I can't do it all in the ObjectDataSource event handlers as I can't access the controls inside my Grid's Edit Form.) I've been playing with the ExtractValues and UpdateValues methods of the GridEditableItem object, but I'm not having any luck. Any tips would be greatly appreciated :)

  • How to safely use PayPal IPN with Asp.Net MVC

    - by Picflight
    Here are two sources for PayPal IPN: Kona.Web IPN DotNetNuke IPN DNN has a loop in the beginning of the Page_Load method that captures txn_type and txn_id, which I don't see in the Kona code. DNN also captures payer email and other information into local variables. I am trying to make sure that I incorporate some of the security checks that I see in DNN into my MVC IPN. How do I do what DNN is doing with MVC 2 with Kona as the base? Is the Kona.Web IPN safe for production, does it need some more tweaking?

  • Using Toad with 64bit Oracle Client and Windows 7 64bit Operating System

    - by Andy5
    After downloading the latest version of Toad for Windows 7 64bit, I am struggling to get it to connect to the database using the existing full Oracle Client that is already on the desktop. The Oracle Client that is there is a 64bit version and is version 12c. When running Toad it says that there is no Oracle Client installed. All of the environment variables have been set up to point to the Oracle Client I note from the attached link that when using Toad in a 64bit os that you have to use a 32bit client? Is this still the case? If not how do I get it to use the Oracle Client? I cannot use another version because of the application that is using it needs that version. http://www.quest.com/toad-development-suite-for-oracle/ Thanks

  • How to use Winmerge with Git Extensions?

    - by sebastiaan
    I'm using Git Extensions and it pre-installs and sets up KDiff as the diff tool to solve merge conflicts. I'm very fond of Winmerge though and would like to replace KDiff with Winmerge. In the Git Extensions settings, there are settings to change the Mergetool, but I can't seem to figure out what syntax I should use and why. There seem to be 4 variables: $BASE, $LOCAL, $REMOTE, $MERGED. It seems that I should pass these to WinMergeU.exe, but with which command line parameters? I've tried to search for this a few times, but there is no answer that actually seems to work.

  • Prevent Python from caching the imported modules

    - by Olivier
    While developing a largeish project (split in several files and folders) in Python with IPython, I run into the trouble of cached imported modules. The problem is that instructions import module only reads the module once, even if that module has changed! So each time I change something in my package, I have to quit and restart IPython. Painful. Is there any way to properly force reloading some modules? Or, better, to somehow prevent Python from caching them? I tried several approaches, but none works. In particular I run into really, really weird bugs, like some modules or variables mysteriously becoming equal to None... The only sensible resource I found is Reloading Python modules, from pyunit, but I have not checked it. I would like something like that. A good alternative would be for IPython to restart, or restart the Python interpreter somehow. So, if you develop in Python, what solution have you found to this problem?

  • MPMoviePlayerController fullscreen quirk in iPad

    - by hgpc
    I want to show a MPMoviePlayerController in a view controller and let the user toggle full screen with the default controls, like the YouTube app. I'm using the following code in a bare-bones example: - (void)viewDidLoad { [super viewDidLoad]; self.player = [[MPMoviePlayerController alloc] init]; self.player.contentURL = theURL; self.player.view.frame = self.viewForMovie.bounds; self.player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.viewForMovie addSubview:player.view]; [self.player play]; } This works well until the user makes the video full screen, rotates the device and taps on the screen. The status bar is shown in the wrong position, as shown in the screenshot below. http://yfrog.com/5fimg0006ryp I'm working with the template Tab Bar Application for iPad. I've only added the viewDidLoad above, the view variables and an UIView in the XIB to show the movie player. What am I doing wrong?

  • Scheduling runtime-specified Activity in Workflow 4 RC

    - by johnny g
    Hi, so I have this requirement to kick off Activities provided to me at run-time. To facilitate this, I have set up a WorkflowService that receives Activities as Xaml, hydrates them, and kicks them off. Sounds simple enough ... ... this is my WorkflowService in Xaml <Activity x:Class="Workflow.Services.WorkflowService.WorkflowService" ... xmlns:local1="clr-namespace:Workflow.Activities" > <Sequence sap:VirtualizedContainerService.HintSize="277,272"> <Sequence.Variables> <Variable x:TypeArguments="local:Workflow" Name="Workflow" /> </Sequence.Variables> <sap:WorkflowViewStateService.ViewState> <scg3:Dictionary x:TypeArguments="x:String, x:Object"> <x:Boolean x:Key="IsExpanded">True</x:Boolean> </scg3:Dictionary> </sap:WorkflowViewStateService.ViewState> <p:Receive CanCreateInstance="True" DisplayName="ReceiveSubmitWorkflow" sap:VirtualizedContainerService.HintSize="255,86" OperationName="SubmitWorkflow" ServiceContractName="IWorkflowService"> <p:ReceiveParametersContent> <OutArgument x:TypeArguments="local:Workflow" x:Key="workflow">[Workflow]</OutArgument> </p:ReceiveParametersContent> </p:Receive> <local1:InvokeActivity Activity="[ActivityXamlServices.Load(New System.IO.StringReader(Workflow.Xaml))]" sap:VirtualizedContainerService.HintSize="255,22" /> </Sequence> </Activity> ... which, except for repetitive use of "Workflow" is pretty straight forward. In fact, it's just a Sequence with a Receive and [currently] a custom Activity called InvokeActivity. Get to that in a bit. Receive Activity accepts a custom type, [DataContract] public class Workflow { [DataMember] public string Xaml { get; set; } } which contains a string whose contents are to be interpreted as Xaml. You can see the VB expression that then converts this Xaml to an Activity and passes it on. Now this second bit, the custom InvokeActivity is where I have questions. First question: 1) given an arbitrary task, provided at runtime [as described above] is it possible to kick off this Activity using Activities that ship with WF4RC, out of the box? I'm fairly new, and thought I did a good job going through the API and existing documentation, but may as well ask :) Second: 2) my first attempt at implementing a custom InvokeActivity looked like this public sealed class InvokeActivity : NativeActivity { private static readonly ILog _log = LogManager.GetLogger (typeof (InvokeActivity)); public InArgument<Activity> Activity { get; set; } public InvokeActivity () { _log.DebugFormat ("Instantiated."); } protected override void Execute (NativeActivityContext context) { Activity activity = Activity.Get (context); _log.DebugFormat ("Scheduling activity [{0}]...", activity.DisplayName); // throws exception to lack of metadata! :( ActivityInstance instance = context.ScheduleActivity (activity, OnComplete, OnFault); _log.DebugFormat ( "Scheduled activity [{0}] with instance id [{1}].", activity.DisplayName, instance.Id); } protected override void CacheMetadata (NativeActivityMetadata metadata) { // how does one add InArgument<T> to metadata? not easily // is my first guess base.CacheMetadata (metadata); } // private methods private void OnComplete ( NativeActivityContext context, ActivityInstance instance) { _log.DebugFormat ( "Scheduled activity [{0}] with instance id [{1}] has [{2}].", instance.Activity.DisplayName, instance.Id, instance.State); } private void OnFault ( NativeActivityFaultContext context, Exception exception, ActivityInstance instance) { _log.ErrorFormat ( @"Scheduled activity [{0}] with instance id [{1}] has faulted in state [{2}] {3}", instance.Activity.DisplayName, instance.Id, instance.State, exception.ToStringFullStackTrace ()); } } Which attempts to schedule the specified Activity within the current context. Unfortunately, however, this fails. When I attempt to schedule said Activity, the runtime returns with the following exception The provided activity was not part of this workflow definition when its metadata was being processed. The problematic activity named 'DynamicActivity' was provided by the activity named 'InvokeActivity'. Right, so the "dynamic" Activity provided at runtime is not a member of InvokeActivitys metadata. Googled and came across this. Couldn't sort out how to specify an InArgument<Activity> to metadata cache, so my second question is, naturally, how does one address this issue? Is it ill advised to use context.ScheduleActivity (...) in this manner? Third and final, 3) I have settled on this [simpler] solution for the time being, public sealed class InvokeActivity : NativeActivity { private static readonly ILog _log = LogManager.GetLogger (typeof (InvokeActivity)); public InArgument<Activity> Activity { get; set; } public InvokeActivity () { _log.DebugFormat ("Instantiated."); } protected override void Execute (NativeActivityContext context) { Activity activity = Activity.Get (context); _log.DebugFormat ("Invoking activity [{0}] ...", activity.DisplayName); // synchronous execution ... a little less than ideal, this // seems heavy handed, and not entirely semantic-equivalent // to what i want. i really want to invoke this runtime // activity as if it were one of my own, not a separate // process - wrong mentality? WorkflowInvoker.Invoke (activity); _log.DebugFormat ("Invoked activity [{0}].", activity.DisplayName); } } Which simply invokes specified task synchronously within its own runtime instance thingy [use of WF4 vernacular is certainly questionable]. Eventually, I would like to tap into WF's tracking and possibly persistance facilities. So my third and final question is, in terms of what I would like to do [ie kick off arbitrary workflows inbound from client applications] is this the preferred method? Alright, thanks in advance for your time and consideration :)

  • Org-mode properties for Emacs diary anniversaries?

    - by lecodesportif
    I am trying to have the "Birthday" property of an Org-mode contact entry added to the agenda automatically: * John :PROPERTIES: :Name: John :Birthday: 5 4 1900 :END: This can be done manually for each entry using: %%(diary-anniversary 5 4 1900) John's birthday But I don't want to type the date twice. I would like to use the org-entry-get functionality to make diary-anniversary take the values of the Birthday and Name (see the bold text above) properties. This is how I get the correct property values. %%(org-entry-get nil "Name") %%(org-entry-get nil "Birthday") But after several attempts, I still haven't managed to put the values in variables and pass them correctly to diary-anniversary. Any ideas how to do it?

  • Error loading a persisted workflow

    - by fra
    Hi, I have a workflow started and persisted using messaging activities. The correlation between the Start initial command and the Stop final command works well if they're sent within few seconds. Problems begin when the workflow is unloaded, because the following Stop message throws the following FaultException: If LoadWorkflowByInstanceKeyCommand.AssociateLookupKeyToInstanceId is not specified, the LookupInstanceKey must already be associated to an instance, or the LoadWorkflowByInstanceKeyCommand will fail. For this reason, it is invalid to also specify the LookupInstanceKey in the InstanceKeysToAssociate collection if AssociateLookupKeyToInstanceId isn't set Can anybody help me? The variables inside the workflow are of types int and XDocument. Any help appreciated, thank you

  • Setting custom header values in an IIS ISAPI filter

    - by Jon Tackabury
    I have an ISAPI filter that I am using to do URL rewriting for my CMS. I am processing SF_NOTIFY_PREPROC_HEADERS notifications, and trying to do this: DWORD ProcessHeader(HTTP_FILTER_CONTEXT *con, HTTP_FILTER_PREPROC_HEADERS *head) { head->SetHeader(con, "test1", "aaa"); con->AddResponseHeaders(con, "test2:bbb\r\n", 0); return SF_STATUS_REQ_NEXT_NOTIFICATION; } However, I can't seem to read these values using server variables or response headers in classic ASP or PHP. The values are missing. I'm expecting either my "test1" or "test2" header values to appear, but they are not. Am I doing something wrong here?
