  • Haskell simple compilation bug

    - by fmsf
    I'm trying to run this code: let coins = [50, 25, 10, 5, 2,1] let candidate = 11 calculate :: [Int] calculate = [ calculate (x+candidate) | x <- coins, x > candidate] I've read some tutorials, and it worked out ok. I'm trying to solve some small problems to give-me a feel of the language. But I'm stuck at this. test.hs:3:0: parse error (possibly incorrect indentation) Can anyone tell me why? I've started with haskell today so please go easy on the explanations. I've tried to run it like: runghc test.hs ghc test.hs but with: ghci < test.hs it gives this one: <interactive>:1:10: parse error on input `=' Thanks

  • getting window screenshot windows API

    - by Oliver
    Hi, I am trying to make a program to work on top of an existing GUI to annotate it and provide extra calculations and statistical information. I want to do this using image recognition, as I have learned a fair amount about this in University using Matlab and similar things. I can get a handle to the window I want to perform image recognition on, but I don't know how to turn that handle into an image of that window, and all its visible child windows. I suppose I am looking for something like the screenshot function, but restricted to a single window. How would I go about doing this? I suppose I'd need something like a .bmp to mess about with. Also, it would have to be efficient enough that I could call it several times a second without my PC grinding to a halt. Hopefully this isn't an obvious question, I typed some things into google but didn't get anything related.

  • Java service wrapper and additional application command line parameters

    - by Jake
    I'm currently using java service wrapper to wrap a java application that I've developed. I'm needing to ability to pass in additional command line parameters to my application through the java service wrapper. Pretend my app is called myapp and I've setup java service wrapper so that the script I run to start is called myapp. I'd like to be able to do something like this: ./myapp start Parameter1 parameter2 and have those additional parameters get passed into my application. Any ideas how to do this? I'm finding that googling and looking at the documentation is only pulling up how to use command line arguments to setup java service wrapper. I've had difficulty finding anything about passing command line arguments to your application except for having them hard coded in your wrapper.conf file. Right now I feel like my option is to take the additional command line parameters, set them to environment variables and have those hard coded in the wrapper.conf. I'd prefer not to go down that road though and am hoping I've overlooked something.

  • Redirect Output of Capistrano

    - by Eric Lubow
    I have a Capistrano deploy file (Capfile) that is rather large, contains a few namespaces and generally has a lot of information already in it. My ultimate goal is, using the Tinder gem, paste the output of the entire deployment into Campfire. I have Tinder setup properly already. I looked into using the Capistrano capture method, but that only works for the first host. Additionally that would be a lot of work to go through and add something like: output << capture 'foocommand' Specifically, I am looking to capture the output of any deployment from that file into a variable (in addition to putting it to STDOUT so I can see it), then pass that output in the variable into a function called notify_campfire. Since the notify_campfire function is getting called at the end of a task (every task regardless of the namespace), it should have the task name available to it and the output (which is stored in that output variable). Any thoughts on how to accomplish this would be greatly appreciated.

  • Split a html string in N parts

    - by Matt Brailsford
    Hi Guys, Does anybody have an example of spliting a html string (coming from a tiny mce editor) and splitting it into N parts using C#? I need to split the string evenly without splitting words. I was thinking of just splitting the html and using the HtmlAgilityPack to try and fix the broken tags. Though I'm not sure how to find the split point, as Ideally it should be based purley on the text rather than the html aswell. Anybody got any ideas on how to go about this? Many thanks Matt

So to my understanding in MVVM The View--Sound and Animation The ViewModel--If some value is true, i would like to play the Sound and Animation on the view. Now How would I go about doing this. I was told to use interfaces like ISoundService and IAnimationService. Implement in the View and then do what? If possible, a workable bare bone example will help alot.

  • Custom iterator for a class based on two sets

    - by Dan Hook
    I have a class that contains two sets. They both contain the same key type but have different compare operations. I would like to provide an iterator for the class that iterates through the elements of both sets. I want to start with one set, then when I increment an iterator pointing to the last element of the first set, I want to go to the first element of the second set. How do I do this? I would like to preserve the bidirectional iterator semantics of std::set, but if it turns out that implementing a forward iterator is much easier, so be it. I'm willing to use the Boost Iterator library if that would help.

  • HTML Upload Form will only upload files found in the directory of the PHP file.

    - by vette982
    I have an image uploader that uses the imgur.com API and jQuery's .ajax() function to upload images to their servers. However, if I browse for an image using the <input type="file"/> element of the form, it will only be successful in uploading an image if the image file is found in the same directory as the page.php file that the form is found in (shown below). How can I allow the form to upload images from any directory on my computer? page.php: <form action="page.php" method="post"> <input type="file" name="doc" id="doc" /><br/> <input type="image" src="go.gif" name="submit" id="submit" /> </form>

  • Daemon with Clojure/JVM

    - by Isaac Copper
    I'd like to have a small (not doing too damn much) daemon running on a little server, watching a directory for new files being added to it (and any directories in the main one), and calling another Clojure program to deal with that new file. Ideally, each file would be added to a queue (a list represented by a ref in Clojure?) and the main process would take care of those files in the queue on a FIFO basis. My question is: is having a JVM up running this little program all the time too much a resource hog? And do you have any suggestions as to how go about doing this? Thank you very much!

  • XAMPP or MAMP on Mac OS X 10.6.2 (Snow Leopard)

    - by Steve
    I just bought a new MacBook Pro which comes with Snow Leopard 10.6.2 (Mac OS X 10.6.2). I am used to using XAMPP as my local development server on XP. Since Mac OS X is based on Unix, I was thinking on activating/installing all the necessary stuff as I would normally do on Linux. However, I am not quite ready to be playing around with the system at this point so having an external package would be a nice temporary solution I think. The question is whether I should go with MAMP or XAMPP. Does anybody have any suggestions? The Pro and Cons I suppose. As far as I know, Mac OS X comes with Apache2 and PHP5. Would MAMP or XAMPP modify the existing Apache and PHP installation? Any comments on how I should proceed? PS: Eventually I would use the default installation of Apache and PHP, and install a binary package of MySQL but time for development is an essence and I don't have time to familiarize myself with Mac OS X.

  • Continuous builds and Agile vs commit often

    - by Mark Underwood
    Hi All, I'm just doing some formal training in Agile at the moment and one question I have is about the value of Continuous Builds vs value of committing to the version control system often. My understanding with version control is that its better to commit often, because then you have history and the ability to go back to previous changes in a fine grained way. My understanding with Agile and continuous build is that its there to put pressure on the developers to always have working code. That to break the source tree is a taboo thing to do. Now i agree with both of these sentiments, but it occurs to be that sometimes these might be working against each other. You maybe in the middle of a largish code change and want to commit code to make sure you have history, but this will break the source tree. Anybody got any thoughts on this? Cheers Mark.

  • Converting raw bytes into audio sound

    - by Afro Genius
    In my application I inherit a javastreamingaudio class from the freeTTS package then bypass the write method which sends an array of bytes to the SourceDataLine for audio processing. Instead of writing to the data line, I write this and subsequent byte arrays into a buffer which I then bring into my class and try to process into sound. My application processes sound as arrays of floats so I convert to float and try to process but always get static sound back. I am sure this is the way to go but am missing something along the way. I know that sound is processed as frames and each frame is a group of bytes so in my application I have to process the bytes into frames somehow. Am I looking at this the right way? Thanx in advance for any help.

  • Between a jsf page and a managed bean, why the getter method is called twice

    - by Bariscan
    Hi, I have a jsf page with a form has an outputtext in it. The value of outputtext component is called from a backing bean (or managed bean). I know when I code it as #{MyBean.myString} Jsf rename it and calls getMyString() method. However the wierd thing is, when I put a breakpoint to the getter method of this component, I see it is called twice during the page is being rendered. The outputtext is in a h:form, and it is the only component wich is bind to a backingbean. I mean, it is so wierd that jsf should get the value when it first come to the getter method, however it needs to go to the getter method twice. Can you explain what is the reason of this behaviour in jsf? Any help would be appreciated, Best wishes, Baris

  • Is Haskell "mainstream", or is it mainly used by hobbyists and academics?

    - by Asher
    I came across a post where someone wrote something inaccurate about Haskell (won't go into it) and he got flammed for it. Which (pleasantly) surprised me. About 3 years ago I read this joke about Haskell: All the haskell programmers in the world can fit into a 747 and if that plane were to crash no one would care... or something along those lines. Which brings me to my question: how healthy is the Haskell community, anyway? Is Haskell "mainstream"? Is it mainly used by hobbiest and academics or someone making some serious money from it (which is the true yardstick of how good a language is - just kidding, geez!)?

  • Easy to follow LaTeX tutorial on layout?

    - by lexu
    I want to layout a page using LaTeX and distribute text snippets/blocks in predefined locations. Something like this +--------------------------------------------------------+ | +-------------+ | | |bla bla bla| | | |bla bl ab lab| +-------------+ | | |bla bla bla| |bla bla bla| | | |bla bl ab lab| |bla bl ab lab| | | +-------------+ |bla bla bla| | | |bla bl ab lab| | | +-------------+ +----+ | | |more| | | Ich und Du |text| | | Müllers Kuh +----+ | | | +--------------------------------------------------------+ My guess is that I should go about this using a minipage or using boxes like \begin{minipage}[b][2cm]{8cm} \mbox{more} \newline \mbox{text} \newline \end{minipage} Is there a tutorial or a 'how to' page that you know, that shows me how to do this - not a list all LaTeX idioms, I have some books for that. But my books are more focused on command lists, scientific publishing and math ..

  • Calling a method in a view controller from a view

    - by Lakshmie
    I have to invoke a method present in a view controller who's reference is available in the view. When I try to call the method like any other method, for some reason, iPhone just ignores the call. Can somebody explain as to why this happens and also how can I go about invoking this method? In the view I have this method: -(void) touchesBegan :(NSSet *) touches withEvent:(UIEvent *)event{ NSArray* mySubViews = [self subviews]; for (UITouch *touch in touches) { int i = 0; for(; i<[mySubViews count]; i++){ if(CGRectContainsPoint([[mySubViews objectAtIndex:i] frame], [touch locationInView:self])){ break; } } if(i<[mySubViews count]){ // viewController is the reference to the View Controller. [viewController pointToSummary:[touch locationInView:self].y]; NSLog(@"Helloooooo"); break; } } } Whenever the touches event is triggered, Hellooooo gets printed in the console but the method before that is simply ignored

  • Does it take time to deallocate memory?

    - by jm1234567890
    I have a C++ program which, during execution, will allocate about 3-8Gb of memory to store a hash table (I use tr1/unordered_map) and various other data structures. However, at the end of execution, there will be a long pause before returning to shell. For example, at the very end of my main function I have std::cout << "End of execution" << endl; But the execution of my program will go something like $ ./program do stuff... End of execution [long pause of maybe 2 min] $ -- returns to shell Is this expected behavior or am I doing something wrong? I'm guessing that the program is deallocating the memory at the end. But, commercial applications which use large amounts of memory (such as photoshop) do not exhibit this pause when you close the application. Please advise :)

  • iPhone: UITableView Becomes Invisible after Changing the Data it Displays

    - by Alexander Shemshurenko
    Hi I have application with a TabBar that controls several views. In one view, I control connections to different servers. Each server provides a different set of items. I display these items in UITableView on another view. The problem is that the tableview displays OK the first time but if I go back to view number one and change the server, thereby changing the list of items that should be displayed in tableview, the tableview becomes invisible for some reason. If I tap on the screen in the place where it should be, it becomes visible again. I create table view like this UITableView * aTableView = [[UITableView alloc] initWithFrame:CGRectMake(X,Y,Width,Height) style:UITableViewStyleGrouped]; [[self view] addSubview:aTableView]; aTableView.dataSource = self; Ive tried to call reloadData and setNeedsDisplay in viewWillAppear of the UIViewController that hosts this tableview but without success. Any advice? Thanks

  • When to use MVP in Windows Forms .net application?

    - by Janalopa
    I am familiar with MVC/MVP though my question is simple, I'm about to program a simple Instant Messaging software when the engine and communication part is an open API. so my software will have about 3 forms, a splash screen with login details, the options form and a main form with all the functionality like: Friends List, Send message, Received messages (tabbed), search user, etc. In UI perspective, its important for the GUI to be in 1 form in my application. So my question is, for the only complicated form that I'm going to have, is it necessary to implement an MVP design pattern or in this case its better to just go straight forward and put all the logic in 1 place? THANKS Janalopa!

  • Xcode, changing applications subfolder?

    - by fuzzygoat
    Hi have noticed today whilst writing a simple iPhone app that Xcode sometimes starts a new folder in applications, whilst your still working on the same app. /Users/Fuzzygoat/Library/Application Support/iPhone Simulator/User/Applications/4E5EF4F0-F410-46A6-888C-0D23BB97D2DC Does anyone know what causes Xcode to swap to a new app folder (i.e. the one named "4E5EF4F0-F410-46A6-888C-0D23BB97D2DC") EDIT_001: One thing I have noticed is that I have been doing a lot of quitting an application and restarting to check a set of archive methods, and that does tend to confuse it sometimes. A couple of times it has not found saved data, I guess this is just a side effect of constantly running the simulator over and over via Xcode. Things seem to go just fine if I test on the Simulator without Xcode, for a start the folder keeps the same name. NB: I am using NSSearchPathForDirectoriesInDomains to get the documents folder each time. gary

  • Facebox adding commas to input

    - by Ed Woodcock
    I'm using a facebox to display a form inside a lightbox, nothing too exciting (just a couple of datepickers, some textboxes and a checkbox). However, I'm having issues with the postbacks, whenever I post back from the facebox it adds a ',' to the start of the input (so "rabbit" becomes ",rabbit") Now, I saw that there was the same issue with the modalpopup extender from the ajaxcontroltoolkit, so I assume it's a common issue. Can anyone either explain why this is happening, or tell me how to fix it? provide a decent way of fixing this? I have actually done it, and it works very nicely, but I don't really want to answer my own bounty question so someone else give it a go! Cheers, Ed EDIT See attached answer for a correct solution (I fixed this eventually but didn't want to ruin the bounty question so left the answer until afterwards).

  • Rotation Interpolation

    - by Rob
    Hello, NB: I'll present this question in degrees purely for simplicity, radians, degrees, different zero-bearing, the problem is essentially the same. Does anyone have any ideas on the code behind rotational interpolation? Given a linear interpolation function: Lerp(from, to, amount), where amount is 0...1 which returns a value between from and to, by amount. How could I apply this same function to a rotational interpolation between 0 and 360 degrees? Given that degrees should not be returned outside 0 and 360. Given this unit circle for degrees: where from = 45 and to = 315, the algorithm should take the shortest path to the angle, i.e. it should go through zero, to 360 and then to 315 - and not all the way round 90, 180, 270 to 315. Is there a nice way to achieve this? Or is it going to just be a horrid mess of if() blocks? Am I missing some well understood standard way of doing this? Any help would be appreciated.

  • Newbie: UINavigationController is pulling me back from further learning :(

    - by nithin
    I have created a window-based application and my problem is I am unable to create UINavigationController on the go. InFact I don't know how to do that. My AppDelegeate - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after application launch [window addSubview:logInView.view]; [window makeKeyAndVisible]; } here the logInView is an object of @interface LogInViewController : UIViewController { IBOutlet UITextField *usernameField; IBOutlet UITextField *passwordField; IBOutlet UIButton *logInButton; } -(IBAction) logInClick:(id) sender; from the click action of this loginviewcontroller It should be showing the home screen with navigation controller. and I have to add many subviews. My question is where should I init the UINavigationController and where could I write the codes for adding subviews? how to map it with interfacebuilder?
