  • How to fix a gstreamer error

    - by BJsgoodlife
    I upgraded to 14.04 and now gstreamer is not working. What I am trying to accomplish is to hear the audio input on my computer coming from a ham radio. This is the command that I am using: gst-launch pulserc ! pulseink. This is the error message that I am receiving: ERROR: pipeline could not be constructed: no element "pulserc". I am wondering if I should purge gstreamer, or if there is another command that I should put it. Thank you again everyone for all of your help.

  • How to install custom c library?

    - by arijit
    I just wanted to add a c library to Ubuntu which was created by Harvard University for cs50 course. They provided instructions for how to install the library which is listed below. Debian, Ubuntu First become root, as with: sudo su - Then install the CS50 Library as follows: apt-get install gcc wget http://mirror.cs50.net/library/c/cs50-library-c-3.1.zip unzip cs50-library-c-3.1.zip rm -f cs50-library-c-3.1.zip cd cs50-library-c-3.1 gcc -c -ggdb -std=c99 cs50.c -o cs50.o ar rcs libcs50.a cs50.o chmod 0644 cs50.h libcs50.a mkdir -p /usr/local/include chmod 0755 /usr/local/include mv -f cs50.h /usr/local/include mkdir -p /usr/local/lib chmod 0755 /usr/local/lib mv -f libcs50.a /usr/local/lib cd .. rm -rf cs50-library-c-3.1 I did exactly as directed. But the compiler reported “Undefined reference to a function”--the function was Get String. So, I searched for a solution and found one. It said to use the -l switch. Now when I compile I use something like: gcc –o hello.c hello –lcs50 (I don’t remember the exact command.) However, I cannot use the make command, which is easier to use. I understand that there is some problem with linking the library. What is a good solution to this problem?

  • Custom dynamic error pages in Ruby on Rails not working

    - by PlanetMaster
    Hi, I'm trying to implement custom dynamic error pages following this post: http://www.perfectline.co.uk/blog/custom-dynamic-error-pages-in-ruby-on-rails I did exactly what the blog post says. I included config.action_controller.consider_all_requests_local = false in my environment.rb. But is not working. My browser shows: Routing Error No route matches "/555" with {:method=>:get} So, it looks like the rescues are not fired. I get the following in my log file: ActionController::RoutingError (No route matches "/555" with {:method=>:get}): Rendering rescues/layout (not_found) Is there some routing interfering with the code? I'm not sure what to look for. I'm running rails 2.3.5. Here is the routes.rb file: ActionController::Routing::Routes.draw do |map| # routing van property-url map.connect 'buy/:property_type_plural/:province/:city/:address/:house_number', :controller => 'properties' , :action => 'show', :id => 'whatever' map.myimmonatie 'myimmonatie' , :controller => 'myimmonatie/properties', :action => 'index' map.login "login", :controller => "user_sessions", :action => "create", :conditions => {:method => :post} map.login "login", :controller => "user_sessions", :action => "new" map.logout "logout", :controller => "user_sessions", :action => "destroy" map.buy "buy", :controller => 'buy' map.sell "sell", :controller => 'sell' map.home "home", :controller => 'home' map.disclaimer "disclaimer", :controller => 'disclaimer' map.sign_up "sign_up", :controller => 'users', :action => :new map.contact "contact", :controller => 'contact' map.resources :user_sessions map.resources :contact map.resources :password_resets map.resources :messages map.resources :users, :only => [:index,:new,:create,:activate,:edit,:profile,:password] map.resources :images map.resources :activation , :only => [:new,:resend] map.resources :email map.resources :properties, :except => [:index,:destroy] map.namespace :admin do |admin| admin.resources :users admin.resources :properties admin.resources :order_items, :as => :orders admin.resources :blog_posts, :as => :blog end map.connect 'myimmonatie/:action' , :controller => 'users', :id => 'current', :requirements => {:action => /(profile)|(password)|(email)/} map.namespace :myimmonatie do |myimmonatie| myimmonatie.resources :messages, :controller => 'messages' myimmonatie.resources :password, :as => "password", :controller => 'users', :action => 'password' myimmonatie.resources :properties , :controller => 'properties' myimmonatie.resources :orders , :only => [:index,:show,:create,:new] end map.root :controller => "home" map.connect ':controller/:action' map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format' end ActionController::Routing::Translator.translate_from_file('config','i18n-routes.yml')

  • multi-clients web application,should I use custom user controls or a common user control

    - by ValidfroM
    Say my company is going to build a complicated asp.net web form education system. One of the module is web based registration. To make it flexiable, we decide to use user control(ascx) with rule-engine (work flow) regulating all business logic behide them. Thus in future,for different clients, we can simply config basic existing rules or adding new rules.(Rules stored in db or XML per client). Now the question is how to deal with the user controls (ascx)? My opinion is for different client build diffrent user control from scratch. other voice is like reuse existing user controls.

  • VirtualBox and Ubuntu Mount Error

    - by skaz
    I have Ubuntu 10 as the guest OS on a Windows 7 machine. I have been trying to setup shares through VirtualBox, but nothing is working. First, I create the share in VirtualBox and point it to a Windows folder. Then I try to mount the drive in Linux, but I keep getting /sbin/mount.vboxsf: mounting failed with the error: Protocol error I have read so many solutions to this, but none seem to work. I have tried: Using the mount.vboxsf syntax Reinstalling VBox additions Rebooting Enabling and trying as root account Any other ideas? In case I am doing something dumb, here are more details: I made a share called "Test" in VBox Shared folders. Then I made a directory in ubuntu named "test2". Then I tried to execute this command: sudo mount -t vboxsf Test /mnt/test2 Thank you!

  • RemoveHandler Issues with Custom Events

    - by Jeff Certain
    This is a case of things being more complicated that I thought they should be. Since it took a while to figure this one out, I thought it was worth explaining and putting all of the pieces to the answer in one spot. Let me set the stage. Architecturally, I have the notion of generic producers and consumers. These put items onto, and remove items from, a queue. This provides a generic, thread-safe mechanism to load balance the creation and processing of work items in our application. Part of the IProducer(Of T) interface is: 1: Public Interface IProducer(Of T) 2: Event ItemProduced(ByVal sender As IProducer(Of T), ByVal item As T) 3: Event ProductionComplete(ByVal sender As IProducer(Of T)) 4: End Interface Nothing sinister there, is there? In order to simplify our developers’ lives, I wrapped the queue with some functionality to manage the produces and consumers. Since the developer can specify the number of producers and consumers that are spun up, the queue code manages adding event handlers as the producers and consumers are instantiated. Now, we’ve been having some memory leaks and, in order to eliminate the possibility that this was caused by weak references to event handles, I wanted to remove them. This is where it got dicey. My first attempt looked like this: 1: For Each producer As P In Producers 2: RemoveHandler producer.ItemProduced, AddressOf ItemProducedHandler 3: RemoveHandler producer.ProductionComplete, AddressOf ProductionCompleteHandler 4: producer.Dispose() 5: Next What you can’t see in my posted code are the warnings this caused. The 'AddressOf' expression has no effect in this context because the method argument to 'AddressOf' requires a relaxed conversion to the delegate type of the event. Assign the 'AddressOf' expression to a variable, and use the variable to add or remove the method as the handler.  Now, what on earth does that mean? Well, a quick Bing search uncovered a whole bunch of talk about delegates. The first solution I found just changed all parameters in the event handler to Object. Sorry, but no. I used generics precisely because I wanted type safety, not because I wanted to use Object. More searching. Eventually, I found this forum post, where Jeff Shan revealed a missing piece of the puzzle. The other revelation came from Lian_ZA in this post. However, these two only hinted at the solution. Trying some of what they suggested led to finally getting an invalid cast exception that revealed the existence of ItemProducedEventHandler. Hold on a minute! I didn’t create that delegate. There’s nothing even close to that name in my code… except the ItemProduced event in the interface. Could it be? Naaaaah. Hmmm…. Well, as it turns out, there is a delegate created by the compiler for each event. By explicitly creating a delegate that refers to the method in question, implicitly cast to the generated delegate type, I was able to remove the handlers: 1: For Each producer As P In Producers 2: Dim _itemProducedHandler As IProducer(Of T).ItemProducedEventHandler = AddressOf ItemProducedHandler 3: RemoveHandler producer.ItemProduced, _itemProducedHandler 4:  5: Dim _productionCompleteHandler As IProducer(Of T).ProductionCompleteEventHandler = AddressOf ProductionCompleteHandler 6: RemoveHandler producer.ProductionComplete, _productionCompleteHandler 7: producer.Dispose() 8: Next That’s “all” it took to finally be able to remove the event handlers and maintain type-safe code. Hopefully, this will save you the same challenges I had in trying to figure out how to fix this issue!

  • Show only one validation error-message using replaceWith

    - by timkl
    I am currently working with the jQuery validation plugin, and I want to show only one error-message before the form itself. Right now the validation shows all the error-messages on top of each others as they stack up, as you can see in my live example: http://timkjaerlange.com/foobar/stack-stuff/validate-test.html This is my jQuery: $(document).ready(function() { $("form").validate({ rules: { // bunch of rules here, left out to keep it simple }, messages: { // messages goes here }, errorElement: 'div', errorClass: 'error', errorPlacement: function(error, element) { error.insertBefore('form'); // this is what I've got $('div').replaceWith(error); // trying to replace the prev error } }); }); Anybody know how to this? Is this the best way to show only one error-message? Any help is highly appreciated.

  • Alternative to nofollow: custom 302 url shortener?

    - by Dogweather
    Here's the scenario: lots of blogging platforms make it tedious to insert nofollow into links within the post content. I.e., you need to edit the html, format it correctly, etc. I have a client who posts lots of content with links that should be nofollow'ed, and I thought of a novel way to handle this, since the blogging platform they're using makes it hard: I install a URL shortener web app on the client's domain. The shortener works as normal, except it redirects via 302 instead of 301. The pagerank will therefore stay at the shortener's domain, and not flow on to the target site. Part 2: In order to get the pagerank to collect meaningfully, say on the site's home page, the shortened URLs would be generated like this: /link?12345 instead of /link/12345. And then, the path /link would 301 to the home page. This way, the id is a param, not a path element. And thus, all the incoming shortened links are going to one path, which transfers pagerank to the home page. So that's my idea. I wanted to see if anybody could find problems with it. Thanks!

  • MVC-like Autogenerated Pages for Webforms

    - by CccTrash
    I noticed that MVC lets you pass in LINQ to SQL objects to its views and it will autogenerate Create, Update and View Pages based on the LINQtoSQL object. Is there anything for webforms that lets you do this kind of thing? (In a nice way with validators maybe?)

  • Syntax error results in blank page

    - by Philipp
    I am new to wicket and trying to get some things working. One thing that annoys me a lot is that I get a blank (0 chars of text) page whenever there is a syntax error on a page. Striped down example: Test.html header stuff: doctype ... html ... head ... body ... <span wicket:id="msgTest" id="message">MSG</span> footer stuff: /body ... /html Test.java public class Test extends WebPage { public Test() { add(new Label("msgTest", "Hello, World!")); } } This will output the page as expected. Now, lets introduce an error: header stuff: doctype ... html ... head ... body ... <span wicket:id="msgTest2" id="message">MSG</span> footer stuff: /body ... /html I changed the label-id to something different then what the source-file expects. If I run this code I get the already mentioned blank page. However, for every request to a page with such a syntax error I get an error report in the log-file of around 1000+ lines. This error-report is basically just wicket-generated html of a page which describes the error. This makes me wonder why wicket isn't displaying the error-stuff instead of the blank page. I'm not very experienced with wicket but to me it somehow looks like wicket is having trouble rendering its own error-page code. It would be nice to know how one goes about finding syntax-errors with wicket. Reading through a 1000+ line error-report for a small error like a misplaced character seems a bit tedious. Thanks in advance for guiding me into the right direction :) PS: wicket-version: 1.4.9 stage: development

  • Making money from a custom built interpreter?

    - by annoying_squid
    I have been making considerable progress lately on building an interpreter. I am building it from NASM assembly code (for the core engine) and C (cl.exe the Microsoft compiler for the parser). I really don't have a lot of time but I have a lot of good ideas on how to build this so it appeals to a certain niche market. I'd love to finish this but I need to face reality here ... unless I can make some good monetary return on my investment, there is not a lot of time for me to invest. So I ask the following questions to anyone out there, especially those who have experience in monetizing their programs: 1) How easy is it for a programmer to make good money from one design? (I know this is vague but it will be interesting to hear from those who have experience or know of others' experiences). 2) What are the biggest obstacles to making money from a programming design? 3) For the parser, I am using the Microsoft compiler (no IDE) I got from visual express, so will this be an issue? Will I have to pay royalties or a license fee? 4) As far as I know NASM is a 2-clause BSD licensed application. So this should allow me to use NASM for commericial development unless I am missing something? It's good to know these things before launching into the meat and potatoes of the project.

  • WPF - copy/paste selection with custom font family

    - by summergoat
    I have a custom font family embedded in my WPF application which I can reference by specifying a base URI and font family name. new FontFamily(new Uri("pack://application:,,,/Fonts/"), "./#My Custom Font Family"); However, when I copy a selection which uses this font the xaml on the clipboard resembles the following <Run Text="Foo" FontFamily="./#My Custom Font Family" /> When I paste into the same RichTextBox I lose the font as it falls back to the system default because - When a FontFamily is specified as an attribute in markup, the base URI value is always implied—its value is the URI of the XAML page. http://msdn.microsoft.com/en-us/library/system.windows.media.fontfamily.aspx and my xaml page is not located in the same directory as the custom font family. Any ideas for a workaround?

  • A very useful custom component

    - by Kevin Smith
    Whenever I am debugging a problem in WebCenter Content (WCC) I often find it useful to see the contents of the internal data binder used by WCC when executing a service. I want to know the value of all parameters passed in by the caller, either a user in the web GUI or from an application calling the service via RIDC or web services. I also want to the know the value of binder variables calculated by WCC as it processes a service. What defaults has it applied based on configuration settings or profile rules? What values has it derived based on the user input? To help with this I created a  component that uses a java filter to dump out the contents of the internal data binder to the WCC trace file. It dumps the binder contents using the toString() method. You can register this filter code using many different filter hooks to see how the binder is updated as WCC processes the service. By default, it uses the validateStandard filter hook which is useful during a CHECKIN service. It uses the system trace section, so make sure that trace section is enabled before looking for the output from this component. Here is some sample output>system/6    10.09 09:57:40.648    IdcServer-1    filter: postParseDataForServiceRequest, binder start -- system/6    10.09 09:57:40.698    IdcServer-1    *** LocalData *** system/6    10.09 09:57:40.698    IdcServer-1    (10 keys + 0 defaults) system/6    10.09 09:57:40.698    IdcServer-1    ClientEncoding=UTF-8 system/6    10.09 09:57:40.698    IdcServer-1    IdcService=CHECKIN_UNIVERSAL system/6    10.09 09:57:40.698    IdcServer-1    NoHttpHeaders=0 system/6    10.09 09:57:40.698    IdcServer-1    UserDateFormat=iso8601 system/6    10.09 09:57:40.698    IdcServer-1    UserTimeZone=UTC system/6    10.09 09:57:40.698    IdcServer-1    dDocTitle=Check in from RIDC using Framework Folder system/6    10.09 09:57:40.698    IdcServer-1    dDocType=Document system/6    10.09 09:57:40.698    IdcServer-1    dSecurityGroup=Public system/6    10.09 09:57:40.698    IdcServer-1    parentFolderPath=/folder1/folder2 system/6    10.09 09:57:40.698    IdcServer-1    primaryFile=testfile5.bin     system/6    10.09 09:57:40.698    IdcServer-1    ***  RESULT SETS  ***>system/6    10.09 09:57:40.698    IdcServer-1    binder end -------------------------------------------- See the readme included in the component for more details.
