  • Nintendo DS homebrew with Ada?

    - by TraumaPony
    Note: I know very little about the GCC toolchain, so this question may not make much sense. Since GCC includes an Ada front end, and it can emit ARM, and devKitPro is based on GCC, is it possible to use Ada instead of C/C++ for writing code on the DS? Edit: It seems that the target that devKitARM uses is arm-eabi.

  • Method name collision in interface implementation - Java

    - by Bhaskar
    If I have two interfaces , both quite different in their purposes , but with same method signature , how do I make a class implement both without being forced to write a single method that serves for the both the interfaces and writing some convoluted logic in the method implementation that checks for which type of object the call is being made and invoke proper code ? In C# , this is overcome by what is called as explicit interface implementation. Is there any equivalent way in Java ?

  • Any Open Source Pregel like framework for distributed processing of large Graphs?

    - by Akshay Bhat
    Google has described a novel framework for distributed processing on Massive Graphs. http://portal.acm.org/citation.cfm?id=1582716.1582723 I wanted to know if similar to Hadoop (Map-Reduce) are there any open source implementations of this framework? I am actually in process of writing a Pseudo distributed one using python and multiprocessing module and thus wanted to know if someone else has also tried implementing it. Since public information about this framework is extremely scarce. (A link above and a blog post at Google Research)

  • How to add data from an NSTextField to a Core Data Attribute without having to press Return or Tab a

    - by roy-fleming
    I use a sheet with 3 NSTextFields and a Cancel- and OK-Button to edit the attributes of a Core Data Entity. The text entered in the NSTextFields is only updated in the Core Data Entity if i press Tab or Return after writing in the NSTextField or if i focus another NSTextField with the mouse. If i just enter text in an NSTextField and press the OK-Button the entered text is lost. Is there some attribute i can set in Interface Builder to change this NSTextField behaviour?

  • How to import data to SAP

    - by Mehmet AVSAR
    Hi, As a complete stranger in town of SAP, I want to transfer my own application's (mobile salesforce automation) data to SAP. My application has records of customers, stocks, inventory, invoices (and waybills), cheques, payments, collections, stock transfer data etc. I have an additional database which holds matchings of records. ie. A customer with ID 345 in my application has key 120-035-0223 in SAP. Every record, for sure, has to know it's counterpart, including parameters. After searching Google and SAP help site for a day, I covered that it's going to be a bit more pain than I expected. Especially SAP site does not give even a clue on it. Say I couldn't find. We transferred our data to some other ERP systems, some of which wanted XML files, some other exposed their APIs. My point is, is Sql Server's SSIS an option for me? I hope it is, so I can fight on my own territory. Since client requests would vary a lot, I count flexibility as most important criteria. Also, I want to transfer as much data as I could. Any help is appreciated. Regards,

  • Ideal Multi-Developer Lamp Stack?

    - by devians
    I would like to build an 'ideal' lamp development stack. Dual Server (Virtualised, ESX) Apache / PHP on one, Databases (MySQL, PgSQL, etc) on the other. User (Developer) Manageable mini environments, or instance. Each developer instance shares the top level config (available modules and default config etc) A developer should have control over their apache and php version for each project. A developer might be able to change minor settings, ie magicquotes on for legacy code. Each project would determine its database provider in its code The idea is that it is one administrate-able server that I can control, and provide globally configured things like APC, Memcached, XDebug etc. Then by moving into subsets for each project, i can allow my users to quickly control their environments for various projects. Essentially I'm proposing the typical system of a developer running their own stack on their own machine, but centralised. In this way I'd hope to avoid problems like Cross OS code problems, database inconsistencies, slightly different installs producing bugs etc. I'm happy to manage this in custom builds from source, but if at all possible it would be great to have a large portion of it managed with some sort of package management. We typically use CentOS, so yum? Has anyone ever built anything like this before? Is there something turnkey that is similar to what I have described? Are there any useful guides I should be reading in order to build something like this?

  • Hyphens or underscores in CSS and HTML identifiers?

    - by Török Gábor
    As both hyphen (-) and underscore (_) are valid characters in CSS and HTML identifiers, what are the advantages and disadvantages using one or the other? I prefer writing CSS class names with hyphens (e.g. field-text) and underscores for IDs (e.g. featured_content). Is there a best practice or it's only the matter of taste?

  • Comprehensive and well maintained wiki syntax Parser for PHP

    - by Rowan
    I'm looking for a comprehensive and well maintained wiki syntax Parser for PHP, does anybody know of one? I can find some really good parsers for markdown and bbcode but am having trouble with finding a decent wiki parser. I prefer markdown myself, but I'm writing post functions for a CMS and I'd like to give end-users a choice. I thought about downloading a copy of MediaWiki and seeing how they do it, thoughts on this as an option?

  • Setting ViewController delegates in iPhone runtime

    - by Stein Rune Risa
    I am writing an iPhone application and needed to use the address book functionality. For this to work, it is necessary to specify a ABPeoplePickerNavigationControllerDelegate on the ViewController. The problem is that I am creating all fields and buttons dynamically runtime, and thus does not have any custom ViewController - using only UIViewController class. My question is then - how can I specify the delegate runtime without having to create a ViewController class just for this purpose.

  • How to get stack trace of a running process from within a Visual Studio add-in?

    - by Jack
    I am writing a Visual Studio add-in in C# which will run while I am debugging a process in the same Visual Studio window and I need access to that the process' stack trace from within my add-in. I tried putting this code into my add-in but it returns the add-in's stack trace, not the process I am debugging. System.Diagnostics.StackTrace stacktrace = new System.Diagnostics.StackTrace(true); System.Diagnostics.StackFrame stackframe = stacktrace.GetFrame(0); Any help would be appreciated.

  • Accessing the project system from a Visual Studio MEF Editor extension

    - by Daniel Plaisted
    I'm writing a Visual Studio editor extension using the VS 2010 SDK RC. I'd like to be able to figure out what the references of the current project are. How do I get access to the project corresponding to the current editor? The documentation on editor extensions doesn't seem to include information on how to access non-editor parts of Visual Studio. I did some searching and it looks like in VS2008 you could write add-ins that would access the project system, but I'm trying to get at this functionality from a MEF editor extension.

  • Weird Java Math ,10 ^ 1 = 11?

    - by Simon
    For an exercise I was writing a loop that turns a string into an integer without using the built in functions by multiplying each individual value by its numerical position. 75 would be 7*(10 ^ 1) + 5*(10 ^ 0), for example. However, for some reason (10 ^ 1) keeps coming back as 11. Is there some mistake I have made or an explanation for this?

  • Endpoints or URIs for a WCF client test-drive

    - by Xencor
    I am aware of the Amazon.com exposed URIs ... which I need to sign up for and then on I can use them ... roll-up my sleeves and get some WCF Client test-drive coding. What are the other such publicly exposed end points that reflect real or almost real-time services? Any offerings specifically from Microsoft? I am basically looking for writing WCF clients for both WCF and non-WCF services...RESTful ones and even otherwise.

  • XML invoice specification

    - by stimms
    I am writing an application which produces invoices. Yes, it sucks. I was wondering it there was any agreed upon DTD for invoices? It seems like everybody has their own format. Perhaps there is a collection of XSLTs for tranforming a common standard into lesser known formats?

  • How to get child container reference in View Model

    - by niels-verkaart
    Hello, I´m trying to share a Data Service (Entity Manager) wrapped in a Repository from a ViewModel (called 'AVM') in Module A to a ViewModel (called 'BVM') in Module B, and I can't get this working. We use PRISM/Unity 2.0 This is my scenario: A user may open multiple Customer screens (composite view as mini shell) each with another customer (unit of work). We realize this using child containers. Each child container resolves it's own repository with its own Entity manager (the repository is a singleton within the child container). This is done in module A. The main shell has a main region manager, and each Customer screen with its childcontainer creates a scoped region. In each customer screen there is a View 'AV' (connected to ViewModel 'AVM') with a SubRegion (tab control) registered as 'SubRegion'. We create this with a 'Screen Factory' In Module B we have a Customer Orders in View 'BV' and ViewModel 'BVM'. In the constructor of Module B we get the main container by injection. In the initialize method we resolve the (main) region manager and register View 'BV' with it. In the constructor of View 'BV' a ViewModel 'BVM' is injected/created. Now this works, but the ViewModel 'BVM' cannot get the child container. It only get the main container. Is this doable, or do I have to do this another way? Thanks, Niels

  • Order of the [BITS 16] and [ORG 0x0000] directives

    - by dboarman-FissureStudios
    I am beginning some experimentation in writing a kernel and having fun doing it. I have the basic boot-loader done and the following directives: [BITS 16] [ORG 0x0000] In the kernel tutorial, however, it starts with: [ORG 0x0000] [BITS 16] I was wondering if the order in which these directives are given makes a difference? I am using NASM version 2.06rc2, OpenSUSE 11.2

  • Django - Override admin site's login form

    - by TrojanCentaur
    I'm currently trying to override the default form used in Django 1.4 when logging in to the admin site (my site uses an additional 'token' field required for users who opt in to Two Factor Authentication, and is mandatory for site staff). Django's default form does not support what I need. Currently, I've got a file in my templates/ directory called templates/admin/login.html, which seems to be correctly overriding the template used with the one I use throughout the rest of my site. The contents of the file are simply as below: # admin/login.html: {% extends "login.html" %} The actual login form is as below: # login.html: {% load url from future %}<!DOCTYPE html> <html> <head> <title>Please log in</title> </head> <body> <div id="loginform"> <form method="post" action="{% url 'id.views.auth' %}"> {% csrf_token %} <input type="hidden" name="next" value="{{ next }}" /> {{ form.username.label_tag }}<br/> {{ form.username }}<br/> {{ form.password.label_tag }}<br/> {{ form.password }}<br/> {{ form.token.label_tag }}<br/> {{ form.token }}<br/> <input type="submit" value="Log In" /> </form> </div> </body> </html> My issue is that the form provided works perfectly fine when accessed using my normal login URLs because I supply my own AuthenticationForm as the form to display, but through the Django Admin login route, Django likes to supply it's own form to this template and thus only the username and password fields render. Is there any way I can make this work, or is this something I am just better off 'hard coding' the HTML fields into the form for?
