  • VS 2008 debugger displays integers in hex

    - by Assaf
    Hi Guys, For some reason my Visual Studio debugger has started to show me my integers in Hex. I am programming ASP.net using C#. Does anyone have an idea how can I convince the debugger to display integers in decimal again? Thanks a lot, Assaf.

  • Is there a way to unit test an async method?

    - by Jiho Han
    I am using Xunit and NMock on .NET platform. I am testing a presentation model where a method is asynchronous. The method creates an async task and executes it so the method returns immediately and the state I need to check aren't ready yet. I can set a flag upon finish without modifying the SUT but that would mean I would have to keep checking the flag in a while loop for example, with perhaps timeout. What are my options?

  • #validate does not seem to work correctly with :on => :create/:update

    - by Tobias
    Greetings, I have a custom validation in my exemplary Movie model: class Movie < ActiveRecord::Base validate :it, :on => :create private def it self.errors.add 'foo', 'bar' end end This works on movie creation but also on updating an existing movie. :on => :update will also work for both. Might that be a bug or am I missing something? Best regards Tobias

  • Is the board game "Go" NP complete?

    - by sharkin
    There are plenty of Chess AI's around, and evidently some are good enough to beat some of the world's greatest players. I've heard that many attempts have been made to write successful AI's for the board game Go, but so far nothing has been conceived beyond average amateur level. Could it be that the task of mathematically calculating the optimal move at any given time in Go is an NP-complete problem?

  • Would Ruby on Rails be appropriate for this Foreign Language project?

    - by Lynne Overesch-Maister
    I'm a Spanish professor & computer groupie. About 15 years ago, I authored in HyperCard a series of verb conjugation programs that are now completely out of date with respect to System OS X. I would like to redo these programs myself because I had a lot of fun doing them last time (mostly I coded while my son played in Leaps and Bounds, you know, one of those places where parents take their kids & let them run wild through the tubes...). Colleagues have mentioned using Flash, Director, and various other solutions, but I saw a presentation on RoR at our SIDLIT conference today, and was inspired. I will be parsing and comparing strings (and there are other features on top of that, but that is the main one), "adding" strings relationally indexed in some kind of database(s). It will also have to handle various foreign characters (accents, upside down question marks, etc.). On top of the main process of the program, it will have to provide a practice vs. test mode, keep track of specific answers as well as totals right/wrong, and print a report. Would this be either easier and/or more efficiently done in RoR than in other languages. I am pretty sure that it will work on a Microsoft server, right? Because I think that is where most of our stuff is. I would be programming either on a Mac or a PC, whichever you think is easier. So, in summary, is RoR the way for me to go with this project? If I have some (little) experience programming in Hypercard and C, should I be able to pick RoR up fairly quickly? What things will I need to start (I already saw something called Redhills foreign key migration plugin, which I assume would be beneficial)? I still have my old scripts from hypercard, however what I would really like to do is to combine all six of my former tense-specific programs into one larger program. I figure that it wouldn't be too hard to reference the individual tenses in some way--could that be a class? Many thanks for any help you can give me on this forum.

  • Schema qualified tables with SQLAlchemy, SQLite and Postgresql?

    - by Chris Reid
    I have a Pylons project and a SQLAlchemy model that implements schema qualified tables: class Hockey(Base): __tablename__ = "hockey" __table_args__ = {'schema':'winter'} hockey_id = sa.Column(sa.types.Integer, sa.Sequence('score_id_seq', optional=True), primary_key=True) baseball_id = sa.Column(sa.types.Integer, sa.ForeignKey('summer.baseball.baseball_id')) This code works great with Postgresql but fails when using SQLite on table and foreign key names (due to SQLite's lack of schema support) sqlalchemy.exc.OperationalError: (OperationalError) unknown database "winter" 'PRAGMA "winter".table_info("hockey")' () I'd like to continue using SQLite for dev and testing. Is there a way of have this fail gracefully on SQLite?

  • Any way to override how <choice> element is binded by xsd.exe

    - by code4life
    I have the following elements in my schema: <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:complexType name="optimizeModelBase"> <xs:attribute name="name" type="xs:string"/> </xs:complexType> <xs:complexType name="riskModel"> <xs:complexContent> <xs:extension base="optimizeModelBase"> <xs:attribute name="type" type="xs:string" use="required"/> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="fullCovariance"> <xs:complexContent> <xs:extension base="optimizeModelBase"> <xs:attribute name="fromDate" type="xs:date" use="required"/> <xs:attribute name="toDate" type="xs:date" use="required"/> <xs:attribute name="windowSize" type="xs:int" use="required"/> </xs:extension> </xs:complexContent> </xs:complexType> In my main schema body, I use a element to specify a 1-of situation: <xs:choice id="RiskModelParameter"> <xs:element name="RiskModel" type="riskModel"/> <xs:element name="FullCovariance" type="fullCovariance"/> </xs:choice> When I run xsd.exe, the resulting code is: [System.Xml.Serialization.XmlElementAttribute("FullCovariance", typeof(fullCovariance))] [System.Xml.Serialization.XmlElementAttribute("RiskModel", typeof(riskModel))] public optimizeModelBase Item { get { return this.itemField; } set { this.itemField = value; } } The issue is that the element's ID tag is being ignored, and xsd.exe is arbitrarily naming the property "Item". I have to admit, it's not a big issue, but it's starting to annoy me. What makes this extra annoying is that if I have additional elements at the same level, xsd.exe binds them as "Item1", "Item2", etc. Does anyone know if it's possible to not have xsd.exe name my choice elements as "Item", and instead be able to put in my own property names?

  • RSpec mocking a nested model in Rails - ActionController problem

    - by emson
    Hi All I am having a problem in RSpec when my mock object is asked for a URL by the ActionController. The URL is a Mock one and not a correct resource URL. I am running RSpec 1.3.0 and Rails 2.3.5 Basically I have two models. Where a subject has many notes. class Subject < ActiveRecord::Base validates_presence_of :title has_many :notes end class Note < ActiveRecord::Base validates_presence_of :title belongs_to :subject end My routes.rb file nests these two resources as such: ActionController::Routing::Routes.draw do |map| map.resources :subjects, :has_many => :notes end The NotesController.rb file looks like this: class NotesController < ApplicationController # POST /notes # POST /notes.xml def create @subject = Subject.find(params[:subject_id]) @note = @subject.notes.create!(params[:note]) respond_to do |format| format.html { redirect_to(@subject) } end end end Finally this is my RSpec spec which should simply post my mocked objects to the NotesController and be executed... which it does: it "should create note and redirect to subject without javascript" do # usual rails controller test setup here subject = mock(Subject) Subject.stub(:find).and_return(subject) notes_proxy = mock('association proxy', { "create!" => Note.new }) subject.stub(:notes).and_return(notes_proxy) post :create, :subject_id => subject, :note => { :title => 'note title', :body => 'note body' } end The problem is that when the RSpec post method is called. The NotesController correctly handles the Mock Subject object, and create! the new Note object. However when the NoteController#Create method tries to redirect_to I get the following error: NoMethodError in 'NotesController should create note and redirect to subject without javascript' undefined method `spec_mocks_mock_url' for #<NotesController:0x1034495b8> Now this is caused by a bit of Rails trickery that passes an ActiveRecord object (@subject, in our case, which isn't ActiveRecord but a Mock object), eventually to url_for who passes all the options to the Rails' Routing, which then determines the URL. My question is how can I mock Subject so that the correct options are passed so that I my test passes. I've tried passing in :controller = 'subjects' options but no joy. Is there some other way of doing this? Thanks...

  • RTS AI: where to start?

    - by awegawef
    I'd like to begin tinkering around with an RTS AI, but I'm having trouble finding a good environment to work with, ie a game that has been already created. I have looked at Spring RTS and Bos Wars, but they don't seem to be conducive to creating simple examples. I am not totally opposed to writing my own game environment, it would just take a long time. Does anyone have a suggestion as to how I can get my feet wet without programming my own game?

  • Really "wow" them in the interview

    - by Juliet
    Let me put it to you this way: I'm a top-notch programmer, but a notoriously bad interviewee. I've flunked 3 interviews consecutively because I get so nervous that my voice tightens at least 2 octaves higher and I start visibly shaking -- mind you, I can handle whatever technical questions the interviewer throws at me in that state, but I think it looks bad to come off as a quivering, squeaky-voiced young woman during a job interview. I've just got the personality type of a shy computer programmer. No matter how technical I am, I'm going to get passed up in favor of a smooth talker. I have another interview coming up shortly, and I want to really impress the company. Here are my trouble spots: What can I do to be less nervous during my interview? I always get really excited when I hear I have a face-to-face interview, but get more and more anxious as D-Day the interview approaches. My employers wants me to explain what I used to do at my prior employment. I'm a very chatty person and tend to talk/squeak for 10 minutes at a time. How long or short should I time my answers? On that note, when I'm explaining what I did at prior jobs, what exactly is my interviewer looking for? At some point, my interviewer will ask "do you have any questions for me while you're here?" I should, but what kinds of questions should I ask to show that I'm interested in being employed? My interviewer always asks why I'm looking for a new job. The real reason is that my present salary is $27K/yr [Edit to add: and I've yet to get a raise since I started], and I want to make more money -- otherwise the work environment is fine. How do I sugarcoat "I want to make more money" into something that sounds nicer? I have only one prior programmer job, and I've worked there for 18 months, but I have the skill of someone with 4 to 6 years of experience. What can I say to compete against applicants with more work experience? I took a low-paying $27K/yr programming job just to get my foot in IT, and I've been trying to leverage that job as a stepping stone to better opportunities. I get interviews because I consistently out-score senior-level developers in aptitude tests, and my desired salary range is right in the ballpark of what most companies want to offer. Unfortunately, while I've been a programming as a hobby for 10 years and I'm geared to graduate with my BA in Comp Sci in May '09, employers see me as a junior-level programmer with no degree. I want to prove them wrong and get a job that matches my skill level. I'd appreciate any advice anyone has to offer, especially if they can help me get a better job in the process.

  • @webservice inheritance java

    - by javamonkey79
    I am trying to build a java ee webservice that has a common base class, but the child classes are the actual @webservice classes (and expose the parent class methods as @webmethod's) Like this: public abstract class Parent { @WebMethod public void doSomething(){//...does stuff} } @WebService public class Child extends Parent {} I've tried (and have failed): - annotating the parent class as a webservice as well - making sure all parent methods are annotated with @WebMethod Is this possible, if so, how?

  • Deploying ASP.Net web app with CruiseControl.Net and SVN -- getting rid of .svn folders

    - by Mercury821
    I have a CruiseControl.Net project set up to build an ASP.Net project, using an <svn task to pull the latest code from source control. On a successful build, I use a <buildpublisher to copy the site to a deployment folder. My problem is that the buildpublisher is copying everything to the destination folder, including every .svn folder and its contents. What is the easiest way to strip out the .svn folders before copying to the deployment folder?
