• Why can't I update to 11.04?

  - by user285982

  I am using Ubuntu 10.10 64 bit, and I can browse the internet fine. I am typing this using the machine. When I attempt to use the Ubuntu Update Manager to update to 11.04, I get this error message: Failed to Fetch Fetching the upgrade failed.There may be a network problem. And when I try to change servers, here is what I get: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/maverick/main/source/Sources.gz 404 Not Found [IP: 91.189.91.15 80] It repeats with other lines, 404 not found. Some index files failed to download, they have been ignored, or old ones used instead. Any ideas?

• New Development Snapshot

  I finished all the .NET 4.0 security model changes. If you build from source, you can now (optionally) build on .NET 4.0 and get native .NET 4.0 assemblies that use the new .NET 4.0 security model (and also experimental class gc support). The .NET 2.0 binaries also work on .NET 4.0. This is probably the final development snapshot before the first 0.44 release candidate and it has been tested more than a typical development snapshot. Please start testing ...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.

• Grouping GridView on Windows 8

  - by nmarun

  It took me a few minutes to get the grouping working on the GridView on my Windows 8 app. I’m sharing what I did just so others can get it working sooner and go by the rest of their work. In VS 2012, I added a Grouped Items Page to my Windows 8 application project. By default, the template will add some sample data, so you can just run it to see how things look. Let’s see what it takes to show our custom data on the page. I’ll stat with the data source. 1: public class Team 2: { 3: public Team( string...(read more)

• Print all values in a value object

  - by SKDev

  I have to debug an issue which requires me to print all the values of a Value Object that is returned by a web service call. The Value object is a complex object in the sense, it has another object as its member which in turn has another object. Printing all the values by using get methods is cumbersome. So was wondering if there is a way to break down the value object by any way to get to a primitive level like String or int or Date and print them all using one API? I had a look at the below question but my prob is that i don't have access to the source code of the value object. The sources are in obfuscated jar. http://stackoverflow.com/questions/2413001/how-to-print-values-of-an-object-in-java

• Generating CMakeLists.txt

  - by vanna

  I got a bunch of C++ sources files and headers. They may use external libraries such as Boost e.g. I am interested in the process of building binaries for Windows and *nix. Makefiles (*nix) and .vcproj (Windows) call compilers with some specifications such as the order of compilation, compilation options and stuff. CMakeLists.txt can be used by CMake to build either makefiles or .vcproj and use very helpful commands such as recursive search of files, automatic linkage with known libraries, installers, variables that can be used in source files... Is there any existing tool that would generate a CMakeLists.txt from specified options ? Options could be like : scan this folder and make a library out of it, then scan this other folder and make an executable and automatically link both with Boost as well along with a user friendly installer with generated INSTALL.txt and README.txt. Something very powerful like that.

• bash script ask for root password

  - by VinceBrowning

  I want have a script that I can give to friends which will add repositories and download files, install them without having to use command as they are not command line savey and have no desire to learn. I need to know how to get the script to prompt them for the root password to allow them to do some of these functions. How would I go about this? Please don't hate on them.. Getting them to start using Linux was a big step and I am just happy that they are attempting something new... and it was in the open source world..

• NUnit vs. MsTest: NUnit wins for Unit Testing.

  People are still wondering what are the differences between the two most popular unit testing frameworks in the .NET world: the open source NUnit and the commercial MsTest).

• I finished "Beginning Android Games", should I use its framework?

  - by orod

  I've worked through Mario Zechner's "Beginning Android Games" and have made my own pong and asteroids game using the framework used in the book. I have also downloaded the source code for Replica Island and am able to run that. I like Replica Island's framework over the one I made from reading the book. Some differences are that Replica Island uses different activities for each screen instead of Zechner's Screen class and that Replica Island can use a lot of textures and isn't limited to textures with dimensions of powers of 2. If I'm serious about writing games and apps for Android should I learn Replica Island's framework and use that instead of the one I made while reading Zechner's book?

• Microsoft décide de bannir iTunes de Windows, suite à l'arrivée des doubles standards

  Microsoft décide de bannir iTunes de Windows, suite à l'arrivée des doubles standards Bill Gates vient d'annoncer qu'iTunes serait dorénavant banni de son système d'exploitation Windows. Voici ses déclarations officielles sur le sujet : "Au départ, nous étions très satisfaits qu'Apple ai déployé iTunes sur Windows ; nous avons gagné beaucoup d'utilisateurs grâce à cette seule application. Et puis nous avons entendu dire, par une source fiable, qu'Apple utilisait la même base de code pour iTunes Mac que pour la version Windows. Pire encore, il nous est apparu suite à une inspection plus approfondie qu'iTunes n'utilisait même pas l'API Windows ! Apple a conçu son propre système de scroll sans s'insp...

• Can I exclude files from Rhythmbox library by filetype?

  - by user69245

  I use Band-in-a-box ("BIAB") to create backing tracks to practice my guitar-playing, and keep the source files (filetype .MGU) created by BIAB in the same folder as the MP3 files derived from them. Because I share this folder with colleagues via Dropbox, I'm not in a position to move the .MGU files elsewhere. Every time I start Rhythmbox ("RB") it checks my music folders, and reports "Import Errors" on all the .MGU files. RB apparently ignores a number of unplayable filetypes in music folders - is there a way of adding .MGU to this group? I know I can just ignore the Import Errors, but one of these days there will be an error I would have wanted to know about.

• Boot screen appears to be asking a question but garbled

  - by mark kaylor

  I'm running 12.04 Precise Pangolin, Kernel 3.2.0-32 w/ GNOME 3.4.2 I perused the prior questions/answers and did not find exactly the same problem, I am concerned that AUTOFSCK, Grub or some other critical event that needs some attention ?

• Two HTML elements with same id attribute: How bad is it really?

  - by danludwig

  Just browsing the google maps source code. In their header, they have 2 divs with id="search" one contains the other, and also has jstrack="1" attribute. There is a form separating them like so: <div id="search" jstrack="1"> <form action="/maps" id="...rest isn't important"> ... <div id="search">... Since this is google, I'm assuming it's not a mistake. So how bad can it really be to violate this rule? As long as you are careful in your css and dom selection, why not reuse id's like classes? Does anyone do this on purpose, and if so, why?

• Adding icon to the system tray (notification area)

  - by Moma Antero

  Hello, I have a small audio recording application programmed with GTK/GDK. (see picture). And I would like to add a tray-icon for it so users can control the application window and recording from it. Adding a tray icon: I have planned to use the GtkStatusIcon class for this task. Ref: http://library.gnome.org/devel/gtk/2.11/GtkStatusIcon.html Is GtkStatusIcon the recommended solution that also works in Ubuntu's Unity and in the GNOME 3.0 desktop? I already googled a bit and found a good example on GtkStatusIcon. Could I also use Libindicator for this task? Ref: https://launchpad.net/libindicator

• Resource Managers - Are they any good?

  - by The Communist Duck

  Hey. I've seen many a time in source code, things like this [well, this is more of a pseudo C++ idea of mine] type defshared_ptr ResourcePtr;// for ease ResourcePtr sound1 = resourceManager.Get("boom.ogg"); sound1-Play(); ResourcePtr sprite = resourceManager.Get("sprite.png"); I was just wondering how useful a class like this was, something that: Loaded media files Stored them in memory Did this at the start of a level - loading screen. Cleaned up Rather than having a system of: Resources are held by entities only, or loose. Responsible for own load into memory. The first is a 'manager' as such; something I feel indicates it's wrong to use. However, it allows for something like a vector of resource names to be passed, rather than having to scramble around finding everything that needs to be loaded.

• JEditorPane Code Completion (Part 3)

  - by Geertjan

  The final step is to put an object into the Lookup on key listening in each of the JEditorPanes, e.g., a "City" object for the CityEditorPane and a "Country" object for the CountryEditorPane. Then, within the CompletionProviders, only add items to the CompletionResultSet if the object of interest is in the Lookup. The result is that you can then have different code completions in different JEditorPanes, as shown below: I've also included the Tools | Options | Editor | Code Completion tab, so that the code completion can be customized. The full source code for the example is here: java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.2/misc/CustomerApp
