  • Reinforcement learning with neural networks

    - by Betamoo
    I am working on a project with RL & NN I need to determine the action vector structure which will be fed to a neural network.. I have 3 different actions (A & B & Nothing) each with different powers (e.g A100 A50 B100 B50) I wonder what is the best way to feed these actions to a NN in order to yield best results? 1- feed A/B to input 1, while action power 100/50/Nothing to input 2 2- feed A100/A50/Nothing to input 1, while B100/B50/Nothing to input 2 3- feed A100/A50 to input 1, while B100/B50 to input 2, while Nothing flag to input 3 4- Also to feed 100 & 50 or normalize them to 2 & 1 ? I need reasons why to choose one method Any suggestions are recommended Thanks

  • Create and access folder outside Apache Tomcat webapps folder

    - by Padur
    My web application requires functionality where end users can upload content, that can be later downloaded or viewed by others, the problem with current scheme is If I create such folder as part of your web project under webapps, every time I do deploy your web application (*.war), the content of that directory will be lost (or overridden). I think the best way to accomplish that is to create folder outside of standard tomcat webapps and access it from there, not sure how to do. Please point in correct direction. I am using Tomcat 4.x soon will be moving to 6.x. -Padur

  • Problems with South/Django: not recognizing the Django App

    - by christmasgorilla
    I've got a Django project on my machine and when I try to use South to migrate the data schema, I get several odd errors. Example: $ python manage.py convert_to_south thisLocator /Library/Python/2.6/site-packages/registration/models.py:4: DeprecationWarning: the sha module is deprecated; use the hashlib module instead import sha /Users/cm/code/thisLocator/../thisLocator/batches/models.py:6: DeprecationWarning: the md5 module is deprecated; use hashlib instead import md5 There is no enabled application matching 'thisLocator'. I've followed the South documentation. Settings.py has it in the installed apps, I can run import south from the manage.py shell. Everyone else on my team is calling the app thisLocator. Am I doing something really stupid?

  • how to push data from BlazeDS without recieve message from Flex client?

    - by Teerasej
    Hi, everyone I am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer, so I think you can help me. In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want? How to configure the message-config.xml to get the result like I describe above?

  • C++ linking issue on Visual Studio 2008 when crosslinking different projects on same solution

    - by Luís Guilherme
    I'm using Google Test Framework to set some unit tests. I have got three projects in my solution: FN (my project) FN_test (my tests) gtest (Google Test Framework) I set FN_test to have FN and gtest as references (dependencies), and then I think I'm ready to set up my tests (I've already set everyone to /MTd (not doing this was leading me to linking errors before)). Particularly, I define a class called Embark in FN I would like to test using FN_test. So far, so good. Thus I write a classe called EmbarkTest using googletest, declare a member Embark* and write inside the constructor: EmbarkTest() { e = new Embark(900,2010); } Then , F7 pressed, I get the following: 1>FN_test.obj : error LNK2019: unresolved external symbol "public: __thiscall Embark::Embark(int,int)" (??0Embark@@QAE@HH@Z) referenced in function "protected: __thiscall EmbarkTest::EmbarkTest(void)" (??0EmbarkTest@@IAE@XZ) 1>D:\Users\lg\Product\code\FN\Debug\FN_test.exe : fatal error LNK1120: 1 unresolved externals Does someone know what have I done wrong and/or what can I do to settle this?

  • Is there any performance difference between Debug and Release?

    - by Lazlo
    I'm using MySql Connector .NET to load an account and transfer it to the client. This operation is rather intensive, considering the child elements of the account to load. In Debug mode, it takes, at most, 1 second to load the account. The average would be 500ms. In Release mode, it takes from 1 to 4 seconds to load the account. The average would be 1500ms. Since there is no #if DEBUG directive or the like in my code, I'm wondering where the difference is coming from. Is there a project build option I could change? Or does it have to do with MySql Connector .NET that would have different behaviors depending on the build mode?

  • How do I fix this JBoss EJB client authentication issue?

    - by Rich
    I have an EJB deployed under JBoss (we're moving a project to it from Weblogic), I can get an EJBHome reference to the EJB via a JNDI lookup. The login-config.xml is set to use the module org.jboss.security.auth.spi.BaseCertLoginModule. When my client code tries to invoke the create method via reflection, calling invoke, I get an InvocationException which wraps an AccessException, which wraps a final exception of javax.security.auth.login.FailedLoginException: Password Incorrect/Password Required at org.jboss.security.auth.spi.UsernamePasswordLoginModule.login(UsernamePasswordLoginModule.java:213).... Am I missing some client code to use BaseCertLoginModule instead of UsernamePasswordLoginModule? Thanks in advance, any suggestions appreciated, apologies for not posting the entire stacktrace but it's on a secured network without internet access.

  • coding an array in a class library and make a call to it C#

    - by eddy
    I'm new to C#, so this may be a basic question. What I need to do is put an array such as the one below in a class library and then make a call to it. So I'd want the aproprate picture to appear via the class and this array. I know there's a much simpler way to make certain pictures appear, but this is a requirement for the project. It's an asp.NET website in C#. string[] PictureArray; PictureArray = new string[3]; PictureArray[0] = "~/pics/grl.jpg"; PictureArray[1] = "~/pics/pop.jpg"; PictureArray[2] = "~/pics/str.jpg"; PictureArray[3] = "~/pics/unk.jpg";

  • Flex/Actionscript: Unable to add archive file

    - by biggusjimmus
    I have an Flex 4 application that I am developing in Flash Builder 4. I'm trying to use a library developed by a coworker, which was delivered as an SWC. I added the library to the Library Path in the project properties. Component set: MX + Spark, Framework linkage: Merged into code. When I attempt to instantiate a component from this library, I get the following error: unable to add archive file: [library].swc$locale\en_US\..\..\resources\images\AcceptButton.png (The system cannot find the path specified) When I unzip [library].swc, the image does exist in .\resources\images\AcceptButton.png as I would expect. Any suggestions to go about resolving this would be much appreciated.

  • Renaming CSS classes across HTML files

    - by hekevintran
    If I have 100 HTML files that use a set of CSS classes, is there a utility that I can use to intelligently rename the classes? I know that every editor/IDE has a find/replace in project feature. Using sed you can do the same thing. This is not intelligent because it is a simple string replace. I want to know of a tool that actually understands what a CSS class is and how to replace instances of it. I suppose a fancy regular expression can do the same thing.

  • WSDL: What do I do with it? Add service Reference? Noobie question

    - by Johnny
    Hey guys! I have been given a WSDL with all the method requests and responses, and all the objects I'll need to use for creating a few webmethods. The thing is, I don't know what to do with it. I've added the WSDL as a Service Reference. I can see the methods and structures, I can instantiate them, it's all there, but the project doesn't build as soon as I add the WSDL. "Error 2 The type name 'ServiceReference1' does not exist in the type 'WSPELab.WSPELab' C:\Users\JJ\Documents\Visual Studio 2008\Projects\WSPELab\WSPELab\Service References\ServiceReference1\Reference.cs 21 111 WSPELabSLN Is it a stupid namespace error on my part? EDIT : Forgot to add this. With the WSDL added, can I used the structures it contains directly? Or are they just "listings" for me to implement? Thanks!

  • What operating systems available for an 8-bit microprocessor?

    - by Benoit
    It does not need to be a full fledged OS, but at least have multitasking capabilities (i.e. a scheduler). Please mention what processor architecture it works on. This is a survey, so exact capabilities are not really important. Think of this as being a place to look at for possibilities when your next 8-bit embedded project comes up... I realize that most 8-bit micro do not require an OS, but just as a counter-example, Rabbit Semiconductor offers the RCM3710 processor module with 4 serial ports, a 10-BaseT ethernet port, 512K RAM and 512K Flash. All that for $39. All based around an 8-bit Z80 core. 8-bit does NOT necessarily mean extreme resource constraint.

  • How do you find time for improving your programming skills?

    - by Snehal
    I'm a Java/J2ee programmer working in India. I'm very passionate about programming and I constantly strive to hone my programming skills by reading blogs, solving Project euler questions, learning new technologies, developing small apps etc;. But I find it very difficult to manage my time. Working for 12 hrs a day in office leaves me stressed out and spend my weekends with my family. So i hardly have like 5-6 hrs per week to actually work on something of my interest which will help me improve. How do you manage time so that you find time to improve your current standing? EDIT: 12 hours includes 1hour of travel & 1 hr of break(lunch/coffee). Effectively I work for 10 hours per day in office which is mandated by my organization. -Snehal

So, I have already gone through with Spring's Client Reference Document. So, I got the idea of required classes for the implementation of Client.

So, if anybody gives me some link or tutorial for proper example from that I can learn my client side implementation would be greatly appreciated. Thanks in advance...

  • ASP.NET MVC RememberMe(It's large, please don't quit reading. Have explained the problem in detail a

    - by nccsbim071
    After searching a lot i did not get any answers and finally i had to get back to you. Below i am explaining my problem in detail. It's too long, so please don't quit reading. I have explained my problem in simple language. I have been developing an asp.net mvc project. I am using standard ASP.NET roles and membership. Everything is working fine but the remember me functionality doesn't work at all. I am listing all the details of work. Hope you guys can help me out solve this problem. I simply need this: I need user to login to web application. During login they can either login with remember me or without it. If user logs in with remember me, i want browser to remember them for long time, let's say atleast one year or considerably long time. The way they do it in www.dotnetspider.com,www.codeproject.com,www.daniweb.com and many other sites. If user logs in without remember me, then browser should allow access to website for some 20 -30 minutes and after that their session should expire. Their session should also expire when user logs in and shuts down the browser without logging out. Note: I have succesfully implemented above functionality without using standard asp.net roles and membership by creating my own talbes for user and authenticating against my database table, setting cookie and sessions in my other projects. But for this project we starting from the beginning used standard asp.net roles and membership. We thought it will work and after everything was build at the time of testing it just didn't work. and now we cannot replace the existing functionality with standard asp.net roles and membership with my own custom user tables and all the stuff, you understand what i am taling about. Either there is some kind of bug with standard asp.net roles and membership functionality or i have the whole concept of standard asp.net roles and membership wrong. i have stated what i want above. I think it's very simple and reasonable. What i did Login form with username,password and remember me field. My setting in web.config: <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880"/> </authentication> in My controller action, i have this: FormsAuth.SignIn(userName, rememberMe); public void SignIn(string userName, bool createPersistentCookie) { FormsAuthentication.SetAuthCookie(userName, createPersistentCookie); } Now the problems are following: I have already stated in above section "I simply need this". user can successfully log in to the system. Their session exists for as much minutes as specified in timeout value in web.config. I have also given a sample of my web.config. In my samplem if i set the timeout to 5 minutes,then user session expires after 5 minutes, that's ok. But if user closes the browser and reopen the browser, user can still enter the website without loggin in untill time specified in "timeout" has not passed out. The sliding expiration for timeout value is also working fine. Now if user logs in to the system with remember me checked, user session still expires after 5 minutes. This is not good behaviour, is it?. I mean to say that if user logs in to the system with remember me checked he should be remembered for a long time untill he doesn't logs out of the system or user doesn't manually deletes all the cookies from the browser. If user logs in to the system without remember me checked his session should expire after the timeout period values specified in web.config and also if users closes the browser. The problem is that if user closes the browser and reopens it he can still enter the website without logging in. I search internet a lot on this topic, but i could not get the solution. In the blog post(http://weblogs.asp.net/scottgu/archive/2005/11/08/430011.aspx) made by Scott Gu on exactly the same topic. The users are complaining about the same thing in their comments ut there is no easy solution given in by Mr. Scott. I read it at following places: http://weblogs.asp.net/scottgu/archive/2005/11/08/430011.aspx http://geekswithblogs.net/vivek/archive/2006/09/14/91191.aspx I guess this is a problem of lot's of users. As seem from blog post made by Mr. Scott Gu. Your help will be really appreciated. Thanks in advance.

    i have successful created asp.net web deployment project under visual studio 2008 and everything works fine. However there is a new requirement from my user where they want to browse the location to install the web application instead of using the default install location. Is there anyway to achieve this ? or do i need to use some third party deployment tools? i have tried the sample transformation file on http://www.codeproject.com/KB/install/ChangeVDirWebSetupProject.aspx?fid=295594&fr=1&df=90&mpp=25&noise=3&sort=Position&view=Quick#xx0xx but it only seems to work under vs2005 thanks

  • Dynamic IMAP/Pop3 Email Address Creation

    - by Vadi
    I have a requirement in my project to create dynamic email address on the fly. For example, similar to flickr has the option of uploading photos (or blogger.com has an option of rececing blog posts in predefined email addresses). The email address can be like "[email protected]", once this email address is created what ever the incoming mails will be processed based on certain scenarios. My questions are: What are the solutions available for having our own IMAP/POP3 Server in Windows? Exchange is not an option though, any commercial softwares will do. Is there any way we can have one real email box and that will be masked with alphanumeric email addresss to minimize the creation of email addresses.

  • Vala vapi files documentation

    - by Jordan
    Hi there, I'd like to hack on an existing GLib based C project using vala. Basically what I'm doing is, at the beginning of my build process, using valac to generate .c and .h files from my .vala files and then just compiling the generated files the way I would any .c or .h file. This is probably not the best way, but seems to be working alright for the most part. My problem is that I'm having a hard time accessing my existing C code from my Vala code. Is there an easy way to do this? I've tried writing my own .vapi files (I didn't have any luck with the tool that came with vala), but I can't find any decent documentation on how to write these. Does any exist? Do I need one of these files to call existing C code? Thanks.

  • ASP.NET MVC F# controller action ignoring parameter

    - by Matt H
    Hi. I have a C# ASP.NET MVC project but my controllers are written in F#. For some reason, the following code doesn't work properly. namespace MvcApplication8.Controllers open System.Web.Mvc [<HandleError>] type ImageController() = inherit Controller() member x.Index (i : int) : ActionResult = x.Response.Write i x.View() :> ActionResult The parameter of the action is seemingly ignored. http://localhost:56631/Image/Index/1 = The parameters dictionary contains a null entry for parameter 'i' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Index(Int32)' in 'MvcApplication8.Controllers.ImageController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters The controller otherwise works fine. I know that plenty of people have written F# mvc code, so, any ideas where I'm going wrong?

  • Create MSI for slipstream SQL 2008 install

    I am looking at creating an MSI that will check/install the prerequisites of SQL Server 2008 and after the prerequisites are installed I will start my slipstream 2008 install. I am currently trying to do this through VS 2008 Deployment Projects, but I cannot just simple add the folders of the SQL slipstream into the setup project without recreating the entire folder structure of the SQL install. So my questions are: Is this a possible to do through Deployment Projects? (if yes, please assist with links or help) Is there a better way to do this? (I would prefer not to use WISE)
