  • Minimum Hardware requirements for Android development

    - by vishwanath
    I need information about minimum hardware requirement I need to have better experience in developing Android application. My current configuration is as follows. P4 3.0 GHz, 512 MB of ram. Started with Hello Android development on my machine and experience was sluggish, was using Eclipse Helios for development. Emulator used to take lot of time to start. And running program too. Do I need to upgrade my machine for the development purpose or is there anything else I am missing on my machine(like heavy processing by some other application I might have installed). And If I do need to upgrade, do I need to upgrade my processor too(that counts to new machine actually, which I am not in favor of), or only upgrading RAM will suffice.

  • How do I tell eclipse to auto-generate or retain stubs when it starts and does a clean build?

    - by Erick Robertson
    I'm working on a Java application that uses JavaSpace. We're developing this in Eclipse. There are a couple instances where we are inserting code into the JavaSpace to do some more advanced space notification logic. Doing this requires that we generate stubs for the classes used within the JavaSpace. We use an external script to generate these stubs. The problem is that whenever Eclipse restarts, it does a clean build of the whole application. When it does this, it deletes all the stubs and we have to regenerate them. I would like to find a way to either tell Eclipse not to remove the _stub.class and _skel.class files within the bin folder where the .class files are placed. Either that, or somehow teach Eclipse to generate the stub files whenever it does a rebuild (and I suppose whenever the source files from which the stubs are generated changes). How can I do one of these, so that we don't have to manually build the stubs every time we start up Eclipse?

  • What are the causes and solutions of exception code c0000005 in mscorwks.dll?

    - by Erick
    The exception code c0000005 is thrown from mscorwks.dll when the application is run on Windows Server 2008 R2. Other platforms (WinXP, Server 2003 R2, Windows 7 32-bit and 64-bit) do not present this exception. The event log from a single execution has many of the following event with event ID 1023 raised by the .NET Runtime: .NET Runtime version 2.0.50727.4952 - Fatal Execution Engine Error (7383851A) (80131506) The application itself makes use of a SOAP interface generated by visual studio from a wsdl, a COM object with an embedded interop, and is targeting .Net 4. sfc /scannow was run and found no problems with system files on the affected system. What trouble shooting can be done to identify a solution?

  • How can I link glibc statically with qt

    - by yan bellavance
    I have built a static version of qt and download a static version of glibc. Now I would like to link glibc statically to my qt application. I know about going into the .pro and adding the line LIBS += -L path/to/static_lib but I am wondering if these that is enough? Will it still link glibc statically even though the OS I am building on has the dynamic libraries also? The reason I am doing this is to deploy the application in a standalone manner. (After installing and updating Red Hat 5.3 glibc_2.9 was not found on the target computer)

  • Direct2D window black when not in focus

    - by Saul Rennison
    Hi all, I have a Direct2D window which paints fine when in focus; however, when focus moves to another window (same application or another), the entire window goes black. I pinned the issue down to the use of ID2D1HwndRenderTarget::Clear. This function is vital to my application as without it, painting becomes rather... weird. Is there a way an un-focused Direct2D window can paint as normal (note: WM_PAINT is being called as usual, as is Clear, BeginPaint, etc. all without error) Thanks in advance.

  • Simple object creation with DIY-DI?

    - by Runcible
    I recently ran across this great article by Chad Perry entitled "DIY-DI" or "Do-It-Yourself Dependency Injection". I'm in a position where I'm not yet ready to use a IoC framework, but I want to head in that direction. It seems like DIY-DI is a good first step. However, after reading the article, I'm still a little confused about object creation. Here's a simple example: Using manual constructor dependency injection (not DIY-DI), this is how one must construct a Hotel object: PowerGrid powerGrid; // only one in the entire application WaterSupply waterSupply; // only one in the entire application Staff staff; Rooms rooms; Hotel hotel(staff, rooms, powerGrid, waterSupply); Creating all of these dependency objects makes it difficult to construct the Hotel object in isolation, which means that writing unit tests for Hotel will be difficult. Does using DIY-DI make it easier? What advantage does DIY-DI provide over manual constructor dependency injection?

  • A matter of style

    - by David
    Would you write something like: enum XYZ_TYPE {X=1, Y=2, Z=3}; I saw it and the suffix _TYPE confuses me in the enum context. There is a strong prospect that it is because I am not bright.

  • multiple modules under one solution

    - by Vicky
    I have a project under which various distributed applications are placed; the whole project is under a single dll. Hence, if any issue occurs we need to re-build the whole application to run or import to our server. I am looking for the best possible way to make the build process faster and also bit worried about the size of the DLL. Is it a good way to have separate dll for all the modules or split the application in multiple projects??? Can, anyone suggest the best way or example to deal with this situation. Any help would be appreciated. Thanks in advance.

  • Single Sign on using Shibboleth

    - by user196614
    Hi, I have to implement Single Sign On in my .NET(3.5) project using Shibboleth. Detailed requirement goes this way: 1) I have developped a web application using .NET (3.5) named "abc.com". 2) There are some third party applications which will be launched from "abc.com" 3) If I have logged in to "abc.com" and now if I launch any of the supported third party applications then it should not ask for login information again. From last few days I have been reading Shibboleth from https://spaces.internet2.edu/display/SHIB2/Home I have also installed Identity provider (IdP) and Service Provide (SP) from https://spaces.internet2.edu/display/SHIB2/Installation Still I am unable to make out how my "abc.com", third party application and Shibboleth will fit into one picture? Can anyone please guide me?

  • How to use @PersistentCapable annotation in Scala 2.8

    - by Gero
    Hi, I'm switching from Scala 2.7.7 to Scala 2.8.0RC3 and now a few of my classes don't compile anymore. The problem is in the @PersistentCapable annotation: import javax.jdo.annotations._ import java.util.Date @PersistenceCapable{identityType=IdentityType.APPLICATION} class Counter(dt: Date, cName: String, vl: int) { <.. snip ..> } This code results in the following compilation errors: [ERROR] /Users/gero/prive/kiva/kivanotify-gae/src/main/scala/net/vermaas/kivanotify/model/LoanProcessed.scala:7: error: expected start of definition [INFO] @PersistenceCapable{val identityType = IdentityType.APPLICATION} I already tried a couple of variations, did some Googling but without luck. Any ideas on how I can use the @PersistentCapable annotation with Scala 2.8.0 RC3? Thanks, Gero

  • How do I share a Hibernate SessionFactory across web applications?

    - by Jer
    I have two web applications that are running on a single Tomcat server and are connected to the same database with Hibernate. I am concerned that having two SessionFactory instances running around might cause some issues. Also, since both web applications share much of the same application logic, I thought it would be a good idea to centralize as much as I could. And since I use Spring for DI and Hibernate configuration it would make sense to have a single ApplicationContext as well. How would I go about doing something like this? Do I need to deploy a headless WAR that creates an ApplicationContext and thus a SessionFactory and allow each application access to it? Is this even a good idea?

  • Has anyone run VxWorks on a desktop PC as a target

    - by Steve Roe
    Can I use a desktop PC to run VxWorks as the operating system? In other words, can a standard PC be used as a target processor? I'm not talking about hosting Workbench and a VxSim on the same machine. Rather, I'm considering running just VxWorks (and my application) on a PC. It seems feasible as long as we can configure a board support package, and write or obtain device drivers for the I/O cards on the PCI bus. What I wonder is, has anyone actually done this? I'm interested in saving a bit of money on hardware over a single board computer and cPCI backplane by using a spare desktop sitting around unused. The application is for a test set to be used in a lab. So, I don't need the portability, etc. of a typical embedded processor.

  • Why does Spring Security's BindAuthenticator require read permissions for users?

    - by Thomas
    Hi all, I'm currently implementing/configuring the LDAP authentication of a Java web application using Spring Security 3.0. I'm using Microsoft AD LDS as LDAP server and chose the Spring's BindAuthenticator. I found out that the authentication only works if the authenticated user is a member of the partition's Readers role. The BindAuthenticator tries to read the user's attributes after the authentication, which seems reasonable in scenarios where authorities are retrieved from the directory service. Being new to LDAP and AD, is this an acceptable practise when the application is integrated in an existing AD structure? Can fine-tune an give the user dns only read permissions for their own attributes rather than adding them to the Reader group? Thanks Thomas

  • a better way to initialize database ONCE when rail server starts

    - by Hadi
    i would like to initialize database the first time the server is started, that involve calling a class method. Given the class name is: Product At first i put an .rb file config\initializers\init.rb as it gets automatically called. Everything works ok, until the database is deleted, and i am trying to do rake db:migrate. rake db:migrate fails saying that cannot find 'product' table. inside init.rb = Product.populate_db The solution i came up is: I took out init.rb do rake db:migrate put back init.rb run the server. My rails application is mainly for reporting and the data is seeded from other application, so i have to do the above step everyday Is there a better way to do the initialization?

  • What is the point in using a "real" database modeling tool?

    - by cdeszaq
    We currently have a 10 year old nasty, spaghetti-code-style SQL Server database that we are soon looking to pretty much re-write from scratch as part of a re-write to a large web application. (The existing application will serve as the functional requirements for the next incarnation of the app). Some have suggested we use Visio to do all the diagramming and to generate the DDL, but others have suggested we use a dedicated database design tool, rather than a diagramming tool that is able to export DDL. Is there any benefit to using "real" DB design tools, such as ModelRight, over general tools like Visio? If so, what are those specific benefits? Edit: In a nutshell, what can real/dedicated tools do that something like Visio can't, and how much do these capabilities matter (from a best-practices standpoint, for example)

  • Compress components with gzip - J2EE

    - by Venkata Sirish
    I am looking to improve front-end performance of my application, so I used YSlow tool in Firefox. When I ran this tool for my app, in the YSlow grade tab it showed up a issue 'Grade F on Compress components with gzip'. Seems to be that we need to compress the files(js, css) while sending from the server to client to increase the server response time. My app is a Struts Java application. Can anyone let me know how to compress and send the front end UI files(JS,CSS) from server so that the response time increases and my pages lot fastly? What are the things that I need to do to compress these files in Java at server?
