  • To access parentAM instance from within nestedAM JUnit test class

    - by Abhishek Dwivedi
    In normal model project, the way to access parent AM from within nested AM is simple - ParentAMImpl parentAM =  (ParentAMImpl)this.getRootApplicationModule(); However, the same approach doesn't help in JUnit model project. Use the following approach -  Inside setUp() method --  ParentAM parentAM =  (ParentAM)Configuration.createRootApplicationModule(ROOT_AM, ROOT_AM_CONFIG); Inside tearDown() method -- Configuration.releaseRootApplicationModule(parentAM, true);

  • Where to store global enterprise properties?

    - by shylynx
    I'm faced with a crowd of java applications, which need different global enterprise wide properties for operation, for example: hostname of the central RDBMS, hostname and location of the central self-service portal, host location of central LDAP, host location of central mail server etc. Formally we build each application with a properties file, where all this properties are definied. But that's a very bad solution, because if the hostname of the mail server changes, we need to change the properties files for each application and deploy all applications again. Our idea is to centralize this properties, so that each application can ask for each property at runtime, for example: Idea: Put the properties file to an easy accessible file share. So if we need to change a property, each application uses the new properties. Idea: Put the properties to database. Main disadvantage: we need a dependency to database client libraries for each application. Idea: Put all applications into one big application server, that provides system properties for each application. Main disadvantage: needs deployment of each application to one application server. But that isn't a realistic scenario. Idea: Webservice that provides global enterprise wide properties. Main disadvantage: not very secure, because some properties are passwords or user credentials. What other alternatives are recommended? What is state of the art?

  • Should I use a Class or Dictionary to Store Form Values

    - by Shamim Hafiz
    I am working on a C# .NET Application, where I have a Form with lots of controls. I need to perform computations depending on the values of the controls. Therefore, I need to pass the Form values to a function and inside that function, several helper functions will be called depending on the Control element. Now, I can think of two ways to pass all the Form values: i) Save everything in a Dictionary and pass the Dictionary to the function or ii) Have a class with attributes that corresponds to each of the Form element. Which of these two approaches , or any other, is better?

  • Mentioning a price for a service behind a free app in App Store

    - by David
    We are making a business service and have created an app to be used as a front-end. The app is free, but the service is not. Due to Apple taking 30% of in-app purchases, our service cannot be bought as an in-app purchase. My question is: Could Apple choose to throw out our app if we mention the price of the service in the description of our app in iTunes or in a help-text in the app? It seems unreasonable that this would cause problems, but the potential consequences to our business could be terrible so I want to make sure.

  • Un chercheur utilise le cloud d'Amazon pour hacker les réseaux protégés, en cassant le chiffrage WPA-PSK par force brute

    Un chercheur utilise le cloud d'Amazon pour hacker les réseaux protégés, en cassant le chiffrage WPA-PSK par force brute Un chercheur en sécurité informatique vient de déclarer avoir identifié une manière simple, rapide et économique d'exploiter une faille dans les Amazon Web Services. Il s'agit de Thomas Roth, consultant allemand, qui affirme pouvoir s'infiltrer dans des réseaux protégés. Comment ? Grâce à un programme spécifique, qu'il a écrit et qui tourne sur les ordinateurs basés sur le Cloud d'Amazon. Ce dernier lance alors des attaques par force brute et teste pas loin de 400.000 mots de passes différents par seconde via les machines d'Amazon. La technique s'en prends à un type précis et très co...

  • Class instance clustering in object reference graph for multi-entries serialization

    - by Juh_
    My question is on the best way to cluster a graph of class instances (i.e. objects, the graph nodes) linked by object references (the -directed- edges of the graph) around specifically marked objects. To explain better my question, let me explain my motivation: I currently use a moderately complex system to serialize the data used in my projects: "marked" objects have a specific attributes which stores a "saving entry": the path to an associated file on disc (but it could be done for any storage type providing the suitable interface) Those object can then be serialized automatically (eg: obj.save()) The serialization of a marked object 'a' contains implicitly all objects 'b' for which 'a' has a reference to, directly s.t: a.b = b, or indirectly s.t.: a.c.b = b for some object 'c' This is very simple and basically define specific storage entries to specific objects. I have then "container" type objects that: can be serialized similarly (in fact their are or can-be "marked") they don't serialize in their storage entries the "marked" objects (with direct reference): if a and a.b are both marked, a.save() calls b.save() and stores a.b = storage_entry(b) So, if I serialize 'a', it will serialize automatically all objects that can be reached from 'a' through the object reference graph, possibly in multiples entries. That is what I want, and is usually provides the functionalities I need. However, it is very ad-hoc and there are some structural limitations to this approach: the multi-entry saving can only works through direct connections in "container" objects, and there are situations with undefined behavior such as if two "marked" objects 'a'and 'b' both have a reference to an unmarked object 'c'. In this case my system will stores 'c' in both 'a' and 'b' making an implicit copy which not only double the storage size, but also change the object reference graph after re-loading. I am thinking of generalizing the process. Apart for the practical questions on implementation (I am coding in python, and use Pickle to serialize my objects), there is a general question on the way to attach (cluster) unmarked objects to marked ones. So, my questions are: What are the important issues that should be considered? Basically why not just use any graph parsing algorithm with the "attach to last marked node" behavior. Is there any work done on this problem, practical or theoretical, that I should be aware of? Note: I added the tag graph-database because I think the answer might come from that fields, even if the question is not.

  • Where to store shaders

    - by Mark Ingram
    I have an OpenGL renderer which has a Scene member variable. The Scene object can contain N SceneObjects. I use these SceneObjects for storing the vertex position and any transforms. My question is, where should shaders be stored in this arrangement? I guess they need to be in a central location because multiple objects can use the same shader. But then each object needs access to the shader because it needs to set attributes into the shader. Does anyone have any advice?

  • Saving an interface instance into a Bundle

    - by user22241
    All I've have an interface that allows me to switch between different scenes in my Android game. When the home key is pressed, I am saving all of my states (score, sprite positions etc) into a Bundle. When re-launching, I am restoring all my states and all is OK - however, I can't figure out how to save my 'Scene', thus when I return, it always starts at the default screen which is the 'Main Menu'. How would I go about saving my 'Scene' (into a Bundle)? Code import android.view.MotionEvent; public interface Scene{ void render(); void updateLogic(); boolean onTouchEvent(MotionEvent event); } I assume the interface is the relevant piece of code which is why I've posted that snippet. I set my scene like so: ('options' is an object of my Options class which extends MainMenu (Another custom class) which, in turn implements the interface 'Scene') SceneManager.getInstance().setCurrentScene(options); //Current scene is optionscreen

  • DNS settings for SaaS in the cloud?

    - by Jeremy
    I am building a SaaS product. When a user signs up for an account they must select an alias for their site --------.getlaunchpoint.com. Right now I have an A record *.getlaunchpoint.com that points to the ip address server. However, with Azure I am not given an IP address. The suggested implementation is to make use of a CNAME. I need to create a CNAME for *.getlaunchpoint.com - getlaunchpoint.cloudapp.net GoDaddy does not support CNAME wildcards. Searching on Google I'm getting conflicting information... is CNAME wildcard a bad practice? I run into the same problem with Amazon EC2 if I want to make use of load balancers because you cannot tie a public IP address to an Amazon Load Balancer. Amazon also suggests the use of a CNAME. Any help would be appreciated.

  • Database and query to store and retreive friend list [migrated]

    - by amr Kamboj
    I am developing a module in website to save and retreive friend list. I am using Zend Framework and for DB handling I am using Doctrine(ORM). There are two models: 1) users that stores all the users 2) my_friends that stores the friend list (that is refference table with M:M relation of user) the structure of my_friends is following ...id..........user_id............friend_id........approved.... ...10.........20 ..................25...................1.......... ...10.........21 ..................25...................1.......... ...10.........22 ..................30...................1.......... ...10.........25 ..................30...................1.......... The Doctrine query to retreive friend list id follwing $friends = Doctrine_Query::create()->from('my_friends as mf') ->leftJoin('mf.users as friend') ->where("mf.user_id = 25") ->andWhere("mf.approved = 1"); Suppose I am viewing the user no.- 25. With this query I am only getting the user no.- 30. where as user no.- 25 is also approved friend of user no.- 20 and 21. Please guide me, what should be the query to find all friend and is there any need to change the DB structure.
