  • What would one call this architecture?

    - by Chris
    I have developed a distributed test automation system which consists of two different entities. One entity is responsible for triggering tests runs and monitoring/displaying their progress. The other is responsible for carrying out tests on that host. Both of these entities retrieve data from a central DB. Now, my first thought is that this is clearly a server-client architecture. After all, you have exactly one organizing entity and many entities that communicate with said entity. However, while the supposed clients to communicate to the server via RPC, they are not actually requesting services or information, rather they are simply reporting back test progress, in fact, once the test run has been triggered they can complete their tasks without connection to the server. The request for a service is actually made by the supposed server which triggers the clients to carry out tests. So would this still be considered a server-client architecture or is this something different?

  • Why hamachi time-outs after 5 minutes or so?

    - by Vik89
    I installed hamachi and hamachi-gui on my girlfriend's pc and on my girlfriend's netbook. After 5 minutes or so (even if I keep using it during that time) it loses the connection, I mean I have to 'go offline' and then 'go online' again for it to see my ip again. If I don't and I ping my IP, it says 'Host unreachable'. If I connect with my Mac from the office the problem doesn't exist, so I wouldn't say it is a problem of my hamachi (server) installation, I'm tempted to say it is a problem of my girlfriend's connection, since it happens from her home, and we haven't tried yet to connect from another home with her setup. What would you say? I followed these instructions http://ubuntuforums.org/showthread.php?t=135036

  • What is the preferred/recommend way of running two version of ubuntu side by side

    - by GreyGeek
    I am running 14.04, but I need to run some corporate software/scripts that have been specifically designed for 12.04. I am aware of virtual box/vmware for full virtualization but I am looking for something more lightweight (on my windows machine both come at a significant cost in battery life) closer to os virtualization level. Ideally, I would like something like windows 7/8 compatibility mode: the ability to run a program as if I were on 12.04. Does Ubuntu/Linux have such mechanism? What is the preferred way of running programs/scripts designed for an older version of Ubuntu?

  • Wait random number of minutes

    - by TiborKaraszi
    Why on earth would you want to do that? you ask. Say you have a job that is scheduled to start at the same time over a number of servers. This might be because you have an SQL Server Master/Target server environment (MSX/TSX) or you quite simply script a job and execute that script on several servers. You probably want to spread the load on your SAN and virtual machine host a bit. This is the exact reason I use this procedure. I frequently use MSX servers and I usually add a job step (executing this...(read more)

  • What is the best and cheapest CMS for an E-Commerce site?

    - by kf0l
    My client needs a site customers can use to pay the membership fees and join. It should also track when old members need to pay again. There are some members that will not want to pay online and they want to be able to use the site to manage all payments. The CMS must be cheap to host online, potentially with something like GitHub/Heroku. I am experienced with PHP and RoR. I am using a CMS so once I am done with this project it is easy for them to update. After reading through different posts I think WordPress with an e-commerce Plugin may be the right solution. Spree and WebGUI also looks promising. Thanks for the help.

  • Missing Firefox app icon

    - by frozenkoi
    I'm using Ubuntu 11.04 (upgraded from LTS 10.04) and Firefox (version 11) doesn't show it's icon in the Window List panel, in the Firefox window top left corner (system menu) nor when using ALT+TAB to switch applications. I'm using unity 2D since I'm running ubuntu as a guest in a VMWare virtual machine (Host is windows 7) Instead of the Firefox icon I get what appears to be a generic icon that looks like an app window in the window list and a black rectangle with a curl in the bottom right corner in the ALT+TAB window. How do I fix this so that the proper Firefox icon gets displayed? EDIT: Depending on the icon set chosen in the Appearence settings window sometimes I get the icon, sometimes I don't. When using Ubuntu classic none of the icon sets provide the icon for Firefox.

  • How to install texlive2011?

    - by vrx
    I just moved from Windows to Ubuntu. Software Center in Ubuntu does have texlive2009 package. There is no straightforward installation process from TUG, or from Google search result. I found some installation of Texlive2010 but it does not work. Here are the step: download an texlive2011.iso, 2.3GB and save in local drive mount to a virtual drive install perl tk (ok) "sudo ./install-tl" does not work, "perl ./install-tl" shows pre-installation setting but it does not have the write access to /usr/local/textlive/2011/ Finally, I'm stuck Please guide me with a step by step tutorial or suggest any other solution beside typing in the black screen without knowing what is going on behind the Terminal.

  • Installing VMware Worstation/Player 8.0.4 on Ubuntu 12.10 fails to load with Unable to start services

    - by user106986
    I have been attempting to install this application for a few weeks without any success. I have installed and uninstalled the application and pathes with no change. I have even tried to load a VM in Virtualbox and install the application there to a base install of Ubuntu 12.10 and it still did not install. I have downloaded the patch and modified it to reflect the version of VMware Worstation and Player I am installing. I still receive the same error I saw in the first attempt to install the software. Which leads me to think that I am missing something. The error is: Unable to start services. See log file /tmp/vmware-root/modconfig-7674.log for details. I have the output of the log file if that will help. According to the dialogue box Virtual Network Device and VMware Blocking Filesystem fail to either load or execute. Any help would be greatly appreciated.

  • Is it possible to grant access to a folder in a SVN server using SVN's API?

    - by Splendonia
    I need to develop a web application (Using any language but I'm familiar with Frameworks Symfony2 and Rails), that is able to grant access to a user to a determined folder on another server on the same network from the application's front-end. I found out that SVN has an API and that I could interact with it with PHP or Ruby (Apparently), although I would be willing to program the application on another language, the server where the files are stored is using Windows and I thought on using Virtual SVN server, however I can't find any function on the API to grant users access to files and/or folders or access of any kind, like you usually do using the GUI (VirtualSVN on Windows). Am I missing anything? Is this even possible?

  • Quality web hosts not using c panel [closed]

    - by J4G
    Possible Duplicate: How to find web hosting that meets my requirements? I was an iPower web hosting user before I encountered major problems with their MySQL databases. I recently tried A Small Orange, whose GUI was not compelling, and I quickly learned to loathe c panel. I looked into using GoDaddy, but reviews of their service have been very negative. I was satisfied with iPower's control panel, so something similar would be appropriate. Can anyone recommend a quality web host that includes the following features? *Unlimited bandwidth (200gb or higher) *Unlimited storage (10gb or higher) *High up-time (preferably 95% or higher) *Does not use C panel or other difficult-to-use control panels *Supports multiple MySQL databases *Uses a recent version of PHPmyAdmin

  • Virtualbox Kernel driver not installed

    - by Cyndi
    I tried to use my Virtual Box and this is the error I received - (I just updated to the new Ubuntu also) and I am VERY new at this Linux OS :) Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

  • How to access variables of uninitialized class?

    - by oringe
    So I've gone with a somewhat singleton approach to my game class: #include "myGame.h" int main () { myGame game; return game.Execute(); } But now I need to define a class that accesses variables in the instance of myGame. class MotionState { public: virtual void setWorldTransform (...) { VariableFromMyGameClass++; //<-- !? ...} }; I'm trying to integrate this class into my project from an example that just uses globals. How can I access variables of myGame class in the definition of new classes? Should I give up on my singleton approach?

  • Need help migrating from Wubi

    - by neilh
    I know this question has been asked, but I am looking for specific help with my partition selection. I want to migrate my install from wubi to be a dual boot. When I installed it I choose a small, partition, around 30GB. I am following these instructions: https://help.ubuntu.com/community/MigrateWubi I see sda4 matches that size, but has mount point as '/host', am I okay to use this one? EDIT: Here is a screenshot of my partitions. http://i.imgur.com/ozPe0.png My windows partition is actually not there, that is down as sdb1, so safely out of the way? I can confirm sda4 is the location of the 'virtual partition' and is an otherwise, unused 26GB partition. It's also where I would like to migrate to a full install to.

  • Spurious MachineToApplication Error With VS2010 Deployment

    Often when I'm building my MVC 2 application using Visual Studio 2010, I get the following error: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. On the internet, this error seems to be related to having a nested web.config in your application. I do have such a thing, but it's just the one that came out of the MVC 2 project item template...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • How to get VMware Workstation 8.0.4 work on Ubuntu 12.04 64 bit?

    - by user73987
    I've bought VMware Workstation 8 just today. After the installation I launched it and the application noticed me that "several modules must be compiled and loaded into the running kernel". During the process, VMware noticed me that was impossible to configure Virtual Network Devices and at the end, was impossible to start the services. The last message said that further information could be found at this address: /tmp/vmware-root-975001794/modconfig-22789.log So, I've pasted the content of the log message here. Can you help me or, rather, you suggest to wait for future updates of Ubuntu? My desktop environment is Unity.

  • How does a linked library combined with the main executable program file interact with a kernel?

    - by I ask Questions For a Reason
    I was attempting to find an answer to this, and I did to some degree, but definitely not anywhere good enough to form a respectable, sensible and clear answer. If I am using Windows, Mac, Linux, or nearly any modern made OS for desktop IBM-compatible PCs, laptops, even tablets and smartphones, there's virtual memory. Clearly, compiling, at least on Windows I know this, an executable object file, such as a simple C "Hello World" output to a terminal, will be linked with the standard library, and several other Window's system software, dynamic linked libraries, and the like. However, how does linking all of these executables together or resources form a connectable interaction with, say, a device driver or any other stuff on the lower level?

    Windows Server 2012 offers expanded virtualization capabilities and works with Windows Azure, the software company's cloud platform. It can deliver more than 200 public, private and hybrid cloud services. The goal seems to be to deliver any application on any cloud.

  • Consuming OData based Rest service in C# [en-US]

    - by ruimachado
    Nowadays comunication between applications is an active topic with daily usage and a large amount of pratical appliances. While developing an app in witch I had to consume an OData I found out that combining Linq with my code made this operation pretty easy.The algorithm to consume OData starts with adding a service reference to Visual Studio:After adding the service reference in wich you define the uri to the service, we start building our code.In your code the algorithm is the following:Define the Uri to your OData ServiceDefine the context of your odata, wich contains all entities exposed by the service.Query the context using LinqPrint the resultEasy and simple.Example code:01public static void Main(string[] args){02 03        Uri serviceUri= newUri("http://example.host.odataservice.net/service.svc", UriKind.Absolute);04        ODataService.ServiceEntities context = newODataService.ServiceEntities (serviceUri);05 06        context.Credentials = newSystem.Net.NetworkCredential(Username,Password);07 08         var query = from ServiceObject in context.YourEntity09                     select ServiceObject ;10 11        foreach (var myObject in query)12        {13            Console.WriteLine("\n Field1: {0} | Field2: {1}",14            myObject .Field1, myObject .Field2);15 16        }17}That’s it.Thank you,Rui Machadorpmachado.wordpress.com

  • Domain resolution - local first then external

    - by stefgosselin
    I would like to know how I can configure my dns settings so that domain is resolved locally first, then if not resolved it goes to external DNS. I had this working before, I am using Ubuntu through a VM and need the local domain to resolve first but since I have upgraded I had to reconfigure network and now it works only external, local host file does not seem to even be used. Is there an easy way to check this out? I did slap it up in google but no specific answer seemed to match my case and I too tight on delivery deadline to test-and-try different approaches. You guys rock, thanks.

  • Hosting a website with Windows Azure

    I may be completely misunderstanding what Azure is but is it possible for me to host a basic website on Windows Azure? I have a site that I've built in HTML and CSS that I'd like to upload to Azure but I can't figure out any way to do this. The site claims I can use it for web hosting, but if I can't FTP then I'm not sure how to do this. Is there a simple tutorial somewhere? I couldn't find anything close to what I'm looking for through searching.
