  • How do I make the launcher progress bar work with my application?

    - by Kevin Gurney
    Background Research I am attempting to update the progress bar within the Unity launcher for a simple python/Gtk application created using Quickly called test; however, following the instructions in this video, I have not been able to successfully update the progress bar in the Unity launcher. In the Unity Integration video, Quickly was not used, so the way that the application was structured was slightly different, and the code used in the video does not seem to function properly without modification in a default Quickly ubuntu-application template application. Screenshots Here is a screenshot of the application icon as it is currently displayed in the Unity Launcher. Here is a screenshot of the kind of Unity launcher progress bar functionality that I would like (overlayed on mail icon: wiki.ubuntu.com). Code class TestWindow(Window): __gtype_name__ = "TestWindow" def finish_initializing(self, builder): # pylint: disable=E1002 """Set up the main window""" super(TestWindow, self).finish_initializing(builder) self.AboutDialog = AboutTestDialog self.PreferencesDialog = PreferencesTestDialog # Code for other initialization actions should be added here. self.add_launcher_integration() def add_launcher_integration(self): self.launcher = Unity.LauncherEntry.get_for_desktop_id("test.destkop") self.launcher.set_property("progress", 0.75) self.launcher.set_property("progress_visible", True) Expected Behavior I would expect the above code to show a progress bar that is 75% full overlayed on the icon for the test application in the Unity Launcher, but the application only runs and displays no progress bar when the command quickly run is executed. Problem Investigation I believe that the problem is that I am not properly getting a reference to the application's main window, however, I am not sure how to properly fix this problem. I also believe that the line: self.launcher = Unity.LauncherEntry.get_for_desktop_id("test.destkop") may be another source of complication because Quickly creates .desktop.in files rather than ordinary .desktop files, so I am not sure if that might be causing issues as well. Perhaps, another source of the issue is that I do not entirely understand the difference between .desktop and .desktop.in files. Does it possibly make sense to make a copy of the test.desktop.in file and rename it test.desktop, and place it in /usr/share/applications in order for get_for_desktop_id("test,desktop") to reference the correct .desktop file? Related Research Links Although, I am still not clear on the difference between .desktop and .desktop.in files, I have done some research on .desktop files and I have come across a couple of links: Desktop Entry Files (library.gnome.org) Desktop File Installation Directory (askubuntu.com) Unity Launcher API (wiki.ubuntu.com) Desktop Files: putting your application in the desktop menus (developer.gnome.org) Desktop Menu Specification (standards.freedesktop.org)

  • Jump-start Your Mind

    - by João Angelo
    I haven’t written in a while mostly because I’ve spent my time reading what others wrote and today I’m writing purely motivated by what I just finished reading. Mindfire: Big Ideas for Curious Mind by Scott Berkun was such a pleasure to read and ended up igniting parts of my mind which I have to admit were becoming a bit numb that I felt the urge to take some time to first say thank you to the author and then recommend it to all your curious minds out there. Now, go read it… it’s time well spent.

  • Visual WebGui's XAML based programming for web developers

    - by Webgui
    While ASP.NET provides an event base approach it is completely dismissed when working with AJAX and the richness of the server is lost and replaced with JavaScript programming and couple with a very high security risk. Visual WebGui reinstates the power of the server to AJAX development and provides a statefull yet scalable, server centric architecture that provides the benefits and user productivity of AJAX with the security and developer productivity we had before AJAX stormed into our lives. "When I first came up with the concept of Visual WebGui , I was frustrated by the fragile and complex nature of developing web applications. The contrast in productivity between working in a fully OOP compiled environment vs. scripting even today, with JQuery, Dojo and such, is still huge. Even today the greatest sponsor of JavaScript programming, Google, is offering a framework to avoid JavaScript using Java that compiles to JavaScript (GWT). So I decided to find a way to abstract the complexity or rather delegate the complex job to enable developers to concentrate on the “What” instead of the “How” and embraced the Form based approach," said Guy Peled the inventor of Visual WebGui. Although traditional OOP development still rules the enterprise, the differences between web sites and web applications have blurred and so did the differences between classic developers and web developers. As a result, we now see declarative languages in desktop / backend development environments (WPF / WF) and we see OOP, gaining more and more power in web development (ASP.NET MVC / ASP.NET DOM). However, what has not changed is enterprise need for security, development ROI, reach, highly responsive and interactive UIs and scalability. The advantages that declarative languages and 'on demand' compilation provide over classic development are mostly the flexibility and a more readable initialize component it offers which is what Gizmox is aspiring to do by replacing the designer initialize component with XAML code. The code in this new project template will be compiled on demand using the build provider mechanism ASP.NET has. This means that the performance hit is only on the first request and after that the performance is the same as a prebuilt solution. This will allow the flexibility of a dynamically updated sites and the power of fully blown enterprise applications over web. You can also use prebuilt features available in ASP.NET to enjoy both worlds in production. VWG XAML implementation (VWG Sites) will be the first truly compliable XAML implementation as Microsoft implemented Silverlight and WPF as a runtime markup interpretation opposed to the ASP.NET markup implementation which is compiled to CLR code once. We have chosen to implement the VWG Sites parser as a different way to create CLR code that provides greater performance over the reflection alternative. VWG Sites will also be the first server side XAML UI engine which, while giving the power of XAML, it will not require any plug-ins or installations on the client side. Short demo video of VWG Sites markup. There is also a live sample available here.

  • Redgate ANTS Performance Profiler

    - by Jon Canning
    Seemingly forever I've been working on a business idea, it's a REST API delivering content to mobiles, and I've never really had much idea about its performance. Yes, I have a suite of unit tests and integration tests, but these only tell me that it works, not how well it works. I was also about to embark on a major refactor, swapping the database from MongoDB to RavenDB, and was curious to see if that impacted performance at all, so I needed a profiler that supported IIS Express that I can run my integration tests against, and Google gave me:   http://www.red-gate.com/supportcenter/content/ANTS_Performance_Profiler/help/7.4/app_iise   Excellent. Following the above guide an instance of IIS Express and is launched, as is Internet Explorer. The latter eventually becomes annoying, I would like to decide whether I want a browser opened, but thankfully the guide is wrong in that it can be closed and profiling will continue. So I ran my tests, stopped profiling, and was presented with a call tree listing the endpoints called and allowing me to drill down to the source code beneath.     Although useful and fascinating this wasn't what I was expecting to see, I was after the method timings from the entire test suite. Switching Show to Methods Grid presented me with a list of my methods, with the slowest lit up in red at the top. Marvellous.     I did find that if you switch to Methods Grid before Call tree has loaded, you do not get the red warnings.   StructureMap was very busy, and next on the list was a request filter that I didn't expect to be so overworked. Highlighting it, the source code was presented to me in the bottom window with timings and a nice red indicator to show me where to look. Oh horror, that reflection hack I put in months ago, I'd forgotten all about it. It was calling Validate<T>() which in turn was resolving a validator from StructureMap. Note to self, use //TODO: when leaving smelly code lying around.     Before refactoring, remember to Save Profile Results from the File menu. Annoyingly you are not prompted to save your results when exiting, and using Save Project will only leave you thankful that you have version control and can go back in time to run your tests again.   Having implemented StructureMap’s ForGenericType, I ran my tests again and:     Win, thankyou ANTS (What does ANTS stand for BTW?)   There's definitely room in my toolbox for a profiler; what started out as idle curiosity actually solved a potential problem. When presented with a new codebase I can see enormous benefit from getting an overview of the pipeline from the call tree before drilling into the code, and as a sanity check before release it gives a little more reassurance that you've done your best, and shows you exactly where to look if you haven’t.   Next I’m going to profile a load test.

  • Twitter like character counter - jQuery version

    - by bipinjoshi
    My recent article titled "Displaying a Character Counter for Multiline Textboxes" shows you how to create a character counter like Twitter for multiline textboxes. The articles does so using ASP.NET AJAX client behavior. Here is a jQuery version of the code that does similar job. Note, however, that unlike ASP.NET AJAX client behavior as illustrated in the article the following code takes a "function" based approach to quickly implement similar functionality.http://www.bipinjoshi.net/articles/84e691b2-0306-4911-87bb-875806ba981b.aspx

  • Google Analytics Filters not removing traffic from other domain

    - by Nic Hubbard
    We have a frustrating problem where someone copied our site code including our Google Analytics code. So we are getting stats logged from their site which is very frustrating. I have setup 4 Filters, each trying to disallow any traffic from this other website, but still their traffic is being shown, including on the Real Time section. Do Filters even work to exclude traffic? Here is how I have it setup: Neither of these seem to help at all.
