  • Can Ubuntu be installed in a subdirectory of another Linux variant?

    - by Reid
    I have access to (but not root on) a compute server which is running a Linux distribution that is a few years old. I'd much prefer to use a current Debian-like flavor. Thus, I'm wondering if it is possible to install Ubuntu (or stock Debian) in one of my directories, and use the Ubuntu programs and libraries in preference to what comes with the server. I would need to access arbitrary parts of the server's filesystem, not just the parts under the Ubuntu install. I log in by SSH, so there's no desktop environment needed. But, I would like to be able to use X programs.

  • Redirect public traffic to a different subfolder, while local traffic remains unchanged

    - by ecnepsnai
    I would like to have local (intranet) HTTP traffic go to the /var/www/html folder while any public traffic goes to the subfolder, /var/www/html/public I've tried this configuration, with some variation, in httpd.conf <VirtualHost PRIVATE-IP> DocumentRoot /var/www/html ServerName ecn ErrorLog /var/www/logs/error/private CustomLog /var/www/logs/access/private common </VirtualHost> <VirtualHost PUBLIC-IP> DocumentRoot /var/www/html/public ServerName PUBLIC-DOMAIN-NAME ErrorLog /var/www/logs/error/public CustomLog /var/www/logs/access/public common </VirtualHost> PUBLIC-IP, PRIVATE-IP, and PUBLIC-DOMAIN name are all replaced with the correct values in the actual document. The problem is, local traffic can browse fine but remote traffic is directed to the root folder and getting 403d (because I have that folder blocked off through my .htaccess file). If I append /public to the URL it works fine.

  • Building a Repository Pattern against an EF 5 EDMX Model - Part 1

    - by Juan
    I am part of a year long plus project that is re-writing an existing application for a client.  We have decided to develop the project using Visual Studio 2012 and .NET 4.5.  The project will be using a number of technologies and patterns to include Entity Framework 5, WCF Services, and WPF for the client UI.This is my attempt at documenting some of the successes and failures that I will be coming across in the development of the application.In building the data access layer we have to access a database that has already been designed by a dedicated dba. The dba insists on using Stored Procedures which has made the use of EF a little more difficult.  He will not allow direct table access but we did manage to get him to allow us to use Views.  Since EF 5 does not have good support to do Code First with Stored Procedures, my option was to create a model (EDMX) against the existing database views.   I then had to go select each entity and map the Insert/Update/Delete functions to their respective stored procedure. The next step after I had completed mapping the stored procedures to the entities in the EDMX model was to figure out how to build a generic repository that would work well with Entity Framework 5.  After reading the blog posts below, I adopted much of their code with some changes to allow for the use of Ninject for dependency injection.http://www.tcscblog.com/2012/06/22/entity-framework-generic-repository/ http://www.tugberkugurlu.com/archive/generic-repository-pattern-entity-framework-asp-net-mvc-and-unit-testing-triangle IRepository.cs public interface IRepository : IDisposable where T : class { void Add(T entity); void Update(T entity, int id); T GetById(object key); IQueryable Query(Expression> predicate); IQueryable GetAll(); int SaveChanges(); int SaveChanges(bool validateEntities); } GenericRepository.cs public abstract class GenericRepository : IRepository where T : class { public abstract void Add(T entity); public abstract void Update(T entity, int id); public abstract T GetById(object key); public abstract IQueryable Query(Expression> predicate); public abstract IQueryable GetAll(); public int SaveChanges() { return SaveChanges(true); } public abstract int SaveChanges(bool validateEntities); public abstract void Dispose(); } One of the issues I ran into was trying to do an update. I kept receiving errors so I posted a question on Stack Overflow http://stackoverflow.com/questions/12585664/an-object-with-the-same-key-already-exists-in-the-objectstatemanager-the-object and came up with the following hack. If someone has a better way, please let me know. DbContextRepository.cs public class DbContextRepository : GenericRepository where T : class { protected DbContext Context; protected DbSet DbSet; public DbContextRepository(DbContext context) { if (context == null) throw new ArgumentException("context"); Context = context; DbSet = Context.Set(); } public override void Add(T entity) { if (entity == null) throw new ArgumentException("Cannot add a null entity."); DbSet.Add(entity); } public override void Update(T entity, int id) { if (entity == null) throw new ArgumentException("Cannot update a null entity."); var entry = Context.Entry(entity); if (entry.State == EntityState.Detached) { var attachedEntity = DbSet.Find(id); // Need to have access to key if (attachedEntity != null) { var attachedEntry = Context.Entry(attachedEntity); attachedEntry.CurrentValues.SetValues(entity); } else { entry.State = EntityState.Modified; // This should attach entity } } } public override T GetById(object key) { return DbSet.Find(key); } public override IQueryable Query(Expression> predicate) { return DbSet.Where(predicate); } public override IQueryable GetAll() { return Context.Set(); } public override int SaveChanges(bool validateEntities) { Context.Configuration.ValidateOnSaveEnabled = validateEntities; return Context.SaveChanges(); } #region IDisposable implementation public override void Dispose() { if (Context != null) { Context.Dispose(); GC.SuppressFinalize(this); } } #endregion IDisposable implementation } At this point I am able to start creating individual repositories that are needed and add a Unit of Work.  Stay tuned for the next installment in my path to creating a Repository Pattern against EF5.

  • Is it possible to use the Volume Notifications from Gnome Shell in XFCE?

    - by Uri Herrera
    I somehow had them working before in 11.10 but I don't really remember what did I do back then other than activating "load Gnome components on start up" in the XFCE's settings manager. I've tried the same in 12.04 but doesn't seem to do anything, I specifically ask for the Volume notifications as other notifications used notify-osd or xfce4-notifyd but the volume one was Gnome's (I found that later) As far as I know it uses notification-daemonbut installing it instead of the other two doesn't give me the correct notifications. I'm using XFCE 4.10

  • Un représentant d'Intel très confiant sur l'avenir de MeeGo, Nokia aurait augmenté les salaires des employés travaillant sur l'OS

    Un représentant d'Intel très confiant sur l'avenir de MeeGo Nokia aurait augmenté les salaires des employés travaillant sur l'OS Peter Biddle, ancien employé emblématique de Microsoft actuellement manager général des produits et services chez Intel, s'est exprimé sur la controverse créée par l'annonce du partenariat stratégique entre Nokia et Microsoft.

  • 12.04 server on home network

    - by dustin mantei
    I need advice to help me with a server install, I'm new to ubuntu and linux in general. I have 6 systems in my house, 5 being windows 7 and this laptop that I am typing on is Linux mint 13 Maya. Question is, my wife will not transition to anything. She is stuck in Gates-land. so, can I make a server with ubuntu 12.04 (burnt disc image last night) so that all systems in my home can access and my mother-in-law in another state can also access with a username? That would be awesome and it may convince the war dept (my wife) to change all the systems in my house to ubuntu/linux. Sorry this is so long winded, but all the questions I have seen on this forum don't answer it completely.

  • Windows Azure CDN(Content Delivery Network)

    - by kaleidoscope
    Windows Azure CDN caches your Windows Azure blobs at strategically placed locations to provide maximum bandwidth for delivering your content to users. You can enable CDN delivery for any storage account via the Windows Azure Developer Portal. The CDN provides edge delivery only to blobs that are in public blob containers, which are available for anonymous access. Windows Azure CDN has 18 locations globally (United States, Europe, Asia, Australia and South America) and continues to expand. The benefit of using a CDN is better performance and user experience for users who are farther from the source of the content stored in the Windows Azure Blob service. In addition, Windows Azure CDN provides worldwide high-bandwidth access to serve content for popular events. Current CDN locations in US. For more details please refer to the link.  http://blogs.msdn.com/windowsazure/archive/2009/11/05/introducing-the-windows-azure-content-delivery-network.aspx Sarang

    I have heard about many techniques which are used by developer/software manager to solve hard programming logic or to create flow of an application and this flow will be implemented by developers to create an actual application. Some of the technique which i know, are: Flowchart Screen-Layout Data Flow Diagram E-R Diagram Algorithm of every programs I'd like to know about two facts: (1) Are there any techniques other than this ? (2) Which one is the most suitable to solve hard programming logic and process of application creation?

  • Grub errors dual boot Windows 8 / Ubuntu 12.10

    - by luca-mastro
    I have got a newly bought ASUS N56V with Windows 8 preinstalled. I needed to install Ubuntu so i partitioned the disk and after having disabled the Secure Boot option from Windows 8 i successfully installed Ubuntu 12.10 from a Live USB. The problem is that if i try to access both to Windows 8 (loader) and Windows Recovery System (loader) from the grub menu, these tow errors show: "can't find command 'drivemap' " and "invalid EFI file path" and it goes back to the grub menu. In conclusion I do not have access to my Windows 8 partition but can only use Ubuntu. How can I solve the problem? I am pretty new to the matter. Thank you!

  • Best way of accessing data on different pages

    - by Gaz83
    I'm looking for a way to load data into properties/variables etc and have this information accessible to all the pages of my app. I want the information to be loaded via a background thread to keep UI thread free. Some of the pages will have various properties of their controls binding to these global properties. Here is what I tried. Created a static class. All pages could access the data but can't bind. Changed the static class to a Singleton and used DependencyProperty's. All pages could access data and binding worked fine but cross-threading issues when accessing via background threads. I have read in various places on this subject but haven't really come up with the best method yet for my situation.

  • Passing class names or objects?

    - by nischayn22
    I have a switch statement switch ( $id ) { case 'abc': return 'Animal'; case 'xyz': return 'Human'; //many more } I am returning class names,and use them to call some of their static functions using call_user_func(). Instead I can also create a object of that class, return that and then call the static function from that object as $object::method($param) switch ( $id ) { case 'abc': return new Animal; case 'xyz': return new Human; //many more } Which way is efficient? To make this question broader : I have classes that have mostly all static methods right now, putting them into classes is kind of a grouping idea here (for example the DB table structure of Animal is given by class Animal and so for Human class). I need to access many functions from these classes so the switch needs to give me access to the class

  • New RUP Patch for iSupplier Portal, Sourcing and Supplier Lifecycle Management (SLM)

    - by LuciaC
    Just released - the 12.1.3 Rollup (RUP) Patch 17525552:R12.PRC_PF.B for iSupplier Portal, Sourcing and Supplier Lifecycle Management (SLM). Who should apply this patch? Anyone that is on Release 12.1.3 and is using  iSupplier Portal, Sourcing or Supplier Lifecycle Management (SLM) functionality. The following areas have had major fixes: Prospective Supplier Guided Navigation: The train-navigation is introduced for prospective supplier registration so that prospective suppliers can see all steps needed to successfully register themselves. Supplier Registration Workflow Enhancement: With this release, provided the Approval Management Engine (AME) action required notifications for supplier approval, so that all workflow related features can be enabled. Vacation rules can be set, approvals can be forwarded and more information can be requested through the notification itself.  Additionally AME parallel Approval support for Supplier Registration approvals has been added. Reinstate Supplier Request: Allow buyer to reopen/reinstate the rejected supplier. Supplier is able to access their previously rejected registration again and make changes and resubmit request. Contact Address Association: The prospective supplier is allowed to associate addresses with contacts (including Primary) during the prospective supplier registration process. Primary Contact Enhancement: The prospective supplier can be registered without creating a user account for the primary contact. Mandatory Attributes: In the negotiation requirement creation page, the lookup meaning of 'Internal' has been changed to 'Internal Optional', and a new lookup value with meaning as 'Internal Required' has been added. The values available in the 'Type' dropdown now are Display Only, Internal Optional, Internal Required, Supplier Optional and Supplier Required.  So now during supplier evaluations, internal user response can be set as mandatory by using Internal Required type during requirement creation. Notifications to Supplier:  When the supplier saves and submits their supplier registration request, then a notification with a registration status page link will be sent for further access.  When the buyer approves, rejects or returns the request, the supplier will be notified in an email with the current status. There are also 10 major enhancements included in this RUP. For information about this RUP; including, the fixes and enhancements included, how to access and apply the patch, performing an impact analysis on your system, and testing recommendations, see Doc ID 1591198.1.  Don’t delay apply the patch today!

  • Ways to prevent client seeing my code

    - by James Eggers
    I've got a bit of a strange problem.. Basically, I'm building a fairly complex (un-compiled, interpreted) program in Python. I've been working on most of this code for other purposes for a few months, and therefore don't want my client to be able to simple copy and paste it and then try and sell it (it's worth a fair amount). The other problem is that I need the script to run on a server that my client is paying for. Is there any way I can secure a particular folder on the machine from root access, make it so only one particular can access the directory? The OS is Ubuntu.

  • About cdn architecture to route way

    - by Tony Lee
    Our web system, use the third-party cdn service. Assume that the user set the local dns with the googledns or opendns to visit our web sites, so cdn service will select the closest cdn proxy node. all right, but in fact the user's actual access position might outside there, cdn service may chose the one furthest away from the user node, so static resource access slower.. At present, my idea is if user local set dns server with googledns, and then first one we get the actual ip address of the user, tracerote to test a best routing lines, set up a cookie in user browser, and then set 302 header for response to jump to the which best cdn node. Whether the user's browser side traceroute tool can provide the best route decision-making ? Because we find that, once the user to set local dns server with the foreign network segment, for example : set dns with 8.8.8.8, so cdn routing will choose the foreign service node.
