  • How do I change my username?

    - by Takkat
    Some time ago when I installed Ubuntu I chose a rather stupid username for my account that I do not want to use anymore. How do I change this (including the name of my home directory) without loosing settings for applications? How do I keep permissions and my keys for various authentification (e.g. email, SSH, GPG and more)? What settings could possibly get lost if I changed my username? Both, command-line and graphical solutions are appreciated.

  • I cannot log in after theme change

    - by sssuizaaa
    After changing the gtk-theme in the gnome tweak took I was taken out of the session to the login screen and now I cannot log in. I can only log in using the guest account. So in the grub menu I selected the recovery mode and in the resulting menu I selected root-drop to root shell prompt. Once there I did a couple of things I've found in several pages and in the forums. 1.gsettings reset org.gnome.desktop.interface gtk-theme This is what I got: (process:642):WARNING: Command line 'dbus-launch –autolunch=4438d024dd45ef7fb2d3f4ab0000000f –binary-syntax --close-stderr' exited with non-zero exit status 1: Autolaunch error: X11 initialization failed.\n and nothing changes 2.gconftool-2 --type=string -s /desktop/gnome/interface/gtk_theme Radiance with this I was trying to change the gtk theme to the Radiance one. No strange message this time but it did not work either. I still cannot log in. Any ideas please?? sssuizaaa

    - by Jason Fitzpatrick
    Google60 is a novel little project that mimics the interface of a 1960s-era computer and mashes it up with modern Google search queries. Take it for a spin; you’ll never appreciate the speed of even the slowest modern browser more. While playing with the actual project is enjoyable, make sure to check out the project notes below the interface for an interesting look at design choices and emulating an old machine.

  • Is it okay to have many Abstract classes in your application?

    - by JoseK
    We initially wanted to implement a Strategy pattern with varying implementations of the methods in a commmon interface. These will get picked up at runtime based on user inputs. As it's turned out, we're having Abstract classes implementing 3 - 5 common methods and only one method left for a varying implementation i.e. the Strategy. Update: By many abstract classes I mean there are 6 different high level functionalities i.e. 6 packages , and each has it's Interface + AbstractImpl + (series of Actual Impl). Is this a bad design in any way? Any negative views in terms of later extensibility - I'm preparing for a code/design review with seniors.

  • Cannot add folders to Ubuntu One

    - by Akmur
    I have signed up with Ubuntu One (20GB) and I'm having the following issue: I basically cannot add folders through the panel interface. I have been able to add five folders so far, but I'd like to add some more (yes, they are inside the home folder). I don't get no errors, but nothing is added to the folders list. By using the command line interface like this u1sdtool --create-folder /home/alex/Web it basically hangs. Nothing happens. If I then list the folders with command line, my folder is not there. Any idea? (I'm on 12.10)

  • 10 Awesome Improvements For Desktop Users in Windows 8

    - by Chris Hoffman
    It’s easy to focus on how Windows 8’s new interface doesn’t feel at home on a traditional desktop PC or laptop. But that’s only one part of Windows 8 – the Windows 8 desktop includes a variety of useful improvements. If you’re a desktop user, you owe it to yourself to look over the improvements and consider upgrading. If Microsoft hadn’t removed the traditional Start menu and added a new interface, we’d all be considering Windows 8’s desktop an upgrade.

  • What are the caveats of the event system built on Messenger rather than on classic .NET events?

    - by voroninp
    MVVM Light and PRISM offer messenger to implement event system. the approximate interface looks like the following one: interface Messanger { void Subscribe<TMessageParam>(Action<TMessageParam> action); void Unsubscribe<TMessageParam>(Action<TMessageParam> action); void Unsubscribe<TMessageParam>(objec actionOwner); void Notify<TMessageParam>(TMessageParam param); } Now this model seems beneficial comparing to classic .net events. It works well with Dependency Injection. Actions are stored as weak references so memory leaks are avioded and unsubscribe is not a must. The only annoyance is the need to declare new TMessageParam for each specific message. But everything comes at a cost. And what I'm really worried about is that I see no shortcomings of this approach. Has anoyne the experience of some troubles with this design pattern?

  • How to structure my java packages

    - by MightyPork
    I have a Java library, quite a huge one. I'm asking regarding Best Practices of structuring the source. For example, the logging sybsystem: Option 1: All in one package, named to sort nicely Log - static accessor LogMonitor - interface for log minotor LogMonitorBase - abstract class LogMonitorStdout - print log to console LogWriter - interface for file logger LogWriterSimple - log writer with just one log file LogWriterArchiving - log writer that handles old log files Option 2: Subpackages for Monitors and Writers, with better names Log monitors/LogMonitor monitors/BaseMonitor monitors/StdoutMonitor writers/LogWriter writers/SimpleLog writers/ArchivingLog The second maybe looks better, but perhaps it's not so practical from the java point of view (two extra packages). What do you suggest as the best practice here? A lot in one package, grouped by naming prefixes, or a lot of subpackages with better names?

  • frequency out of range - please change display mode

    - by Dave
    I just downloaded the latest version of the Ubuntu live CD, and have installed it on a desktop computer (a Fujitsu Scaleo P). Once installed it seems to work perfectly, although there are some updates recommended in the Update Manager. My problem is that, after having installed these updates and restarted the computer, I get this message on my monitor, and no Ubuntu interface is visible: frequency out of range - please change display mode I do not know how to change this when I can't access an interface. Is there a command that will bypass trying to boot the GUI and let me change the display mode via a CLI? I am brand new to Ubuntu and any help on this would be much appreciated.

  • Making diff output more readable

    - by mgunes
    I'm looking for a tool that will take diff / debdiff output (and more specifically, the output of this script) and display the result of the comparison in a highly readable, graphical way. Any pointers would be appreciated. Ideally, it would be the GTK+, FOSS equivalent of MDR. Meld, Diffuse and similar software are not fit for this purpose, since they're intended to work standalone, and don't take input from stdin.

  • Directory access control with Apache: do I need to use a specific .htaccess?

    - by Mirror51
    I have an Apache webserver, and in the Apache configuration, I have Alias /backups "/backups" <Directory "/backups"> AllowOverride None Options Indexes Order allow,deny Allow from all </Directory> I can access files via http://127.0.0.1/backups. The problem is everyone can access that. I have a web interface, e.g. http://localhost/adminm that is protected with htaccess and password. Now I don't want separate .htaccess and .htpasswd for /backups, and I don't want a second password prompt when a user clicks on /backups in the web interface. Is there any way to use same .htaccess and .htpasswd for the backups directory?

  • How can you remove Unity?

    - by Brad
    In previous versions of Netbook Remix I was able to disable the netbook-launcher and just have a blank desktop. I liked the speed of the Netbook version but not the interface, this worked well for me. However, now with 10.10 and Unity I'm having trouble doing a similar thing. I tried removing netbook-launcher from the startup and tried uninstalling unity. The best result I got was a black desktop with a panel and a non configurable blank white background. Is Unity soo integrated into this version that I will have to just go with the default ubuntu installation?? In the past the default version has been slower then the Netbook version without the interface. Thanks.

  • Does a code inherit GNU GPL if it just link to GPL library?

    - by user14284
    Sorry for bad English. Suppose there is a library xxx under GNU GPL, that provide a function yyy. Suppose my code links to the library and use this function. Does my code inherit GPL license? IANAL, but my thoughts are conflicting: On one hand, my code is derivative from the library, so it should inherit GPL. On other hand, my code just use link to the xxx. Maybe there are other libraries, that has the same interface (particularly, they provide yyy function with same functionality, but different implementation). My code may link to any. My code really doesn't directly derived from xxx, it just use its interface. So, my code shouldn't inherit GPL. I'm confused. ADDED. The question is absolutely abstract. I don't mean any concrete GPL library.

  • Recomendation for Webshop with API

    - by m.sr
    I'm searching for a webshop. The problem with my search is, that the webshop-software of my choice needs to have a useabel API or some interface for external applications. E.g. i need to place orders by an external application or need to get product descriptions or warehouse stock from the external application. I somehow would like to have a webshop wehere the webinterface is just one way to interact with the whole system. There are some other requirments, which have to be fullfilled, but i guess they are kind of common: running on linux MySQL (we already have MySQL-replication and backup in place) i like open source but i'm willing to pay for it, if it's worth it I found some webshops on the net - but perhaps you can tell me, if theres any hope for a webshop with a good API before i go and test all of them, on the first look i didn't find any docs about any interface to external applications for any of my search results. Thank you!

  • How to remove "Search and launch"?

    - by user38489
    Is it possible to remove the "Search and launch" whateveritis from my "desktop"? I've actually tried both Desktop and Netbook modes, but it stays there in both of them. I'm not afraid of editing files in the ~/.kde dir, but I would be really disappointed if this is the only way to do it. [more details/rants] I was able to wipe out several things but I've ended up with a black window that's movable (Alt-click) but not removable. Beside being surprised by the performances, I find Kubuntu extremely unfriendly, and I can't find the logic behind the items of the interface. I've tried to search for documentation, but what I've found is not updated and doesn't include the Netbook interface.

  • IXRepository and test problems

    - by Ridermansb
    Recently had a doubt about how and where to test repository methods. Let the following situation: I have an interface IRepository like this: public interface IRepository<T> where T: class, IEntity { IQueryable<T> Query(Expression<Func<T, bool>> expression); // ... Omitted } And a generic implementation of IRepository public class Repository<T> : IRepository<T> where T : class, IEntity { public IQueryable<T> Query(Expression<Func<T, bool>> expression) { return All().Where(expression).AsQueryable(); } } This is an implementation base that can be used by any repository. It contains the basic implementation of my ORM. Some repositories have specific filters, in which case we will IEmployeeRepository with a specific filter: public interface IEmployeeRepository : IRepository<Employee> { IQueryable<Employee> GetInactiveEmployees(); } And the implementation of IEmployeeRepository: public class EmployeeRepository : Repository<Employee>, IEmployeeRepository // TODO: I have a dependency with ORM at this point in Repository<Employee>. How to solve? How to test the GetInactiveEmployees method { public IQueryable<Employee> GetInactiveEmployees() { return Query(p => p.Status != StatusEmployeeEnum.Active || p.StartDate < DateTime.Now); } } Questions Is right to inherit Repository<Employee>? The goal is to reuse code once all implementing IRepository already been made. If EmployeeRepository inherit only IEmployeeRepository, I have to literally copy and paste the code of Repository<T>. In our example, in EmployeeRepository : Repository<Employee> our Repository lies in our ORM layer. We have a dependency here with our ORM impossible to perform some unit test. How to create a unit test to ensure that the filter GetInactiveEmployees return all Employees in which the Status != Active and StartDate < DateTime.Now. I can not create a Fake/Mock of IEmployeeRepository because I would be testing? Need to test the actual implementation of GetInactiveEmployees. The complete code can be found on Github

  • What simple offline GUI database should I use for this application?

    - by gcc
    I am looking an open source application. Application should have : * database support ( create two or three table ) * GUI ( what I have created should be seen ) Example : Assume that I have created a table ; X_table : | A | B | C | D | After creating table, I am loading data | A | B | C | D | | 1 | 11 | b | f | - | 3 | 12 | a | o | - data | 4 | 13 | r | o | - When I am opening application not for loading data, I want see data in graphical interface. Are there any open source application which have above feature ? Application can be so simple, * no internet connection * support only one database * static table creation ( once created never changed ) Application can be run Ubuntu 12.04 and/or Windows. In other words, I am wanting database viewer and editor. EDIT: I should load pdf file, image etc. or give path of the file to the application. This link can be reference to my question . ( Interface should be like this, just a list )
