  • Manually output HAML start and end tags

    - by trobrock
    I have some code: - count = 0 - @clients.each do |client| %div{:class => "grid_2#{(" alpha" if (count % 3) == 0) || (" omega push_2" if (count % 3) == 2) || " push_1"}"}= link_to h(client.name), client - count += 1 I want to output an opening div tag right after the each statement if the (count % 3) == 0 and out put the end tag at the end of the block if the (count % 3) == 2 but I can't figure out how to get HAML to do this. Any ideas?

  • Do I need a semaphore for my thread in Android/Java?

    - by Henrik
    Hello all, When running a thread in Android/Java: public void run() { while (running) { if (moreTasksToExec()) { task = getNextTask() task.exec(); } } } Is it OK to let it run and not using a semaphore to block while no work needs to be executed? I am only using one thread, so I need no inter-thread synchronization.

  • How is the default constructor of System.Drawing.Graphics removed?

    - by Albert Iordache
    When I try to create an object of Graphics, why doesn't the following work? System.Drawing.Graphics graphicsObj = new System.Drawing.Graphics(); (I am aware that I could create a private System.Windows.Forms.Panel Obj; and then do CreateGraphics() if I wanted it to work) I tried to find a custom constructor for Graphics, but I couldn't find one. Where did Microsoft define it, or how did it block it?

  • pdf <pre> equivalent

    - by ddowns
    I'm trying to put some code examples in a pdf, but copying them out messes up the formatting and rearranges the lines, there's a lot of manual cleanup needed after pasting. Is there a equivalent to html's pre for PDFs? For "this" block of text respect line breaks, spacing, and copy as plain text like its shown. The closest thing I can see is adding note annotations next to every code example.

  • Alter stored procedure if condition is met

    - by Matt
    I am looking to alter a stored procedure if a condition exists. I want to leave the stored procedure as is if the condition is not met, so drop/create is not really an option. Trying to put the contents of ALTER PROC inside an IF block is throwing up errors for me. Any thoughts?

  • How to create a hover effect in a newsletter?

    - by Moak
    I'm creating a newsletter, and i want to have panels that change background-color on mouse over. Seeing as the newsletter wont have a head, I am defining all styles inline. I'm pretty sure most popular mail clients will block JS. So I was wondering if I can define a hover effect in the style attribute. Or is there any other solution to achieve this effect? Peace

  • Recover lost code from compiled apk

    - by AlexRamallo
    I have an issue here..and its making me really nervous. I was working on this game, and it was going great, so I took a copy of it on my laptop to work do some work while away from my computer. long story short, hard-drive failure + poor back ups led to me losing a very important class. Is there a way to decompile the apk to retrieve the bit of code that was lost? It isn't overly complicated or sophisticated, its just that its impossible to re-write it without reading every. single. line. of. code. in the entire application since it initializes a LOT of classes and loads a bunch of stuff in a specific way. With a quick google search I was able to find apktool, which decompiles it into a bunch of .smali files, which I don't think were designed for human reading. All I need to recover is one very big method in the class. I found the smali file that contains it and I think I found the line where it starts. something like .method public declared-synchronized load(Lcom/X/X/game/X;)I Anyone help would be appreciated since I would have to scrap the entire game without this method.

  • Java's Swing Threading

    - by nevets1219
    My understanding is that if I start up another thread to perform some actions, I would need to SwingUtilities.invokeAndWait or SwingUtilities.invokeLater to update the GUI while I'm in said thread. Please correct me if I'm wrong. What I'm trying to accomplish is relatively straightforward: when the user clicks submit, I want to (before performing any actions) disable the submit button, perform the action, and at the end of the action re-enable the button. My method to perform the action updates the GUI directly (displays results) when it gets the results back. This action basically queries a server and gets some results back. What I have so far is: boolean isRunning = false; synchronized handleButtonClick() { if ( isRunning == false ) { button.setEnabled( false ); isRunning = true; doAction(); } } doAction() { new Thread() { try { doAction(); // Concern A } catch ( ... ) { displayStackTrace( ... ); // Concern B } finally { SwingUtilities.invokeLater ( /* simple Runnable to enable button */ ); isRunning = false; } } } For both of my concerns above, do I would have to use SwingUtilities.invokeAndWait since they both will update the GUI? All GUI updates revolve around updating JTextPane. Do I need to in my thread check if I'm on EDT and if so I can call my code (regardless of whether it updates the GUI or not) and NOT use SwingUtilities.invokeAndWait?

  • Can I write a module/filter that gets fired before the web app get's run in Tomcat?

    - by Blankman
    Can I write a module/filter that gets put into the processing pipleline in Tomcat BEFORE the web application even gets run? Something that I could turn on/off for each web application that tomcat is handling. is this possible? So basically it would be a re-usable filter that hooks into the web pipeline that could alter the requests behavior or perform/modify the requests. One example would be to log all ip's, or redirect based on the url, block the request, etc.

  • GET is not working for firstResource Rest example

    - by Anandan
    Hi, I am newbie to rest. I am using the following code example to understand the RESTlet. http://www.restlet.org/documentation/1.1/firstResource I am using RESTClient addon to firefox for testing. When i do GET on http://localhost/rest, i get a response "ok". But when i do GET on http://localhost/items, I get an error "404 Not found" Here's the sample code: public synchronized Restlet createRoot() { Router router = new Router(getContext()); router.attach("/items", ItemsResource.class); router.attach("/items/{itemName}", ItemResource.class); Restlet restlet = new Restlet() { @Override public void handle(Request request, Response response) { StringBuilder stringBuilder = new StringBuilder(); stringBuilder.append("ok"); response.setEntity(new StringRepresentation(stringBuilder .toString(), MediaType.TEXT_HTML)); } }; router.attach("/rest", restlet); return router; } ItemResource is same as provided in the link. and I use tomcat to run the servlet. Why am I getting the "Not found" error? Am i missing something here? Thanks & Regards, Anandan

  • Create form select from object containing values

    - by marks34
    I have such an object : var options = {1: 'Running', 2: 'Falling', 3: 'Collapsing wall', 4: (...)}; I'd like to create form's select element with ooptions taken from this object, so something like that (code I tried which is not working, but you can get the idea) : html = '<form action="" ><select name="block-action"><option>-------</option>'; for(k in obj){ html += '<option value="'+k+'">'+obj[k]+'</option>' } html += '</select></form>'

  • Does rails do a rollback if I use begin...rescue?

    - by codeman73
    I'd like to add a begin...rescue block to one of my controllers create method, in order to log better info and construct the correct error message to return to the client. Does the rescue in any way 'interrupt' the rollback process? I'm assuming rails automatically does a rollback. When does it happen? Has it already happened by the time I get in the rescue clause? I'm using mySQL on Dreamhost and I think they use innoDB.

  • Elegant and 'correct' multiton implementation in Objective C?

    - by submachine
    Would you call this implementation of a multiton in objective-c 'elegant'? I have programmatically 'disallowed' use of alloc and allocWithZone: because the decision to allocate or not allocate memory needs to be done based on a key. I know for sure that I need to work with only two instances, so I'm using 'switch-case' instead of a map. #import "Multiton.h" static Multiton *firstInstance = nil; static Multiton *secondInstance = nil; @implementation Multiton + (Multiton *) sharedInstanceForDirection:(char)direction { return [[self allocWithKey:direction] init]; } + (id) allocWithKey:(char)key { return [self allocWithZone:nil andKey:key]; } + (id)allocWithZone:(NSZone *)zone andKey:(char)key { Multiton **sharedInstance; @synchronized(self) { switch (key) { case KEY_1: sharedInstance = &firstInstance; break; case KEY_2: sharedInstance = &secondInstance; break; default: [NSException raise:NSInvalidArgumentException format:@"Invalid key"]; break; } if (*sharedInstance == nil) *sharedInstance = [super allocWithZone:zone]; } return *sharedInstance; } + (id) allocWithZone:(NSZone *)zone { //Do not allow use of alloc and allocWithZone [NSException raise:NSObjectInaccessibleException format:@"Use allocWithZone:andKey: or allocWithKey:"]; return nil; } - (id) copyWithZone:(NSZone *)zone { return self; } - (id) retain { return self; } - (unsigned) retainCount { return NSUIntegerMax; } - (void) release { return; } - (id) autorelease { return self; } - (id) init { [super init]; return self; } PS: I've not tried out if this works as yet, but its compiling cleanly :)

  • declerative_authorization on User problem

    - by Webpain
    I am trying to block all default methods except create and update in my users controller using declerative_authorization. But at the time I add filter_resource_access or filter_access_to into my usersController i always get "Couldn't find User without an ID". Anyone care to explain why this could be happening? class UsersController :new end end def show @user = @current_user end def edit @user = @current_user end def update @user = @current_user # makes our views "cleaner" and more consistent if @user.update_attributes(params[:user]) flash[:notice] = "Account updated!" redirect_to account_url else render :action = :edit end end end

  • Wait between tasks with SingleThreadExecutor

    - by Lord.Quackstar
    I am trying to (simply) make a blocking thread queue, where when a task is submitted the method waits until its finished executing. The hard part though is the wait. Here's my 12:30 AM code that I think is overkill: public void sendMsg(final BotMessage msg) { try { Future task; synchronized(msgQueue) { task = msgQueue.submit(new Runnable() { public void run() { sendRawLine("PRIVMSG " + msg.channel + " :" + msg.message); } }); //Add a seperate wait so next runnable doesn't get executed yet but //above one unblocks msgQueue.submit(new Runnable() { public void run() { try { Thread.sleep(Controller.msgWait); } catch (InterruptedException e) { log.error("Wait to send message interupted", e); } } }); } //Block until done task.get(); } catch (ExecutionException e) { log.error("Couldn't schedule send message to be executed", e); } catch (InterruptedException e) { log.error("Wait to send message interupted", e); } } As you can see, there's alot of extra code there just to make it wait 1.7 seconds between tasks. Is there an easier and cleaner solution out there or is this it?
