• Does this pattern have a name?

  - by LK7jb

  Disclaimer: I'm trying to learn proper OO programming/design, so I'm pretty new to this stuff. I guess this is a general design patterns question, but I'll base my example on a game engine or something that renders objects to the display. Consider the following: How can this sort of separation between physical objects (e.g., cubes, spheres, etc.) and the rendering mechanism be achieved in an extensible manner? This design is not set in stone, and perhaps I've got something wrong from the start. I'm just curious as to how a problem like this is solved in real world code.

• Running Java Server Application 24/7 (NOT on local machine) ...?

  - by Steven

  I am currently experimenting with Java Socket Programming and succeeded in creating a simple application that allows me to send data back and forth between a client and a server. I don't want to power my laptop (on which the server application runs) 24/7. Therefore, of course, no computer (that runs my client application) will be able to communicate with my selfmade server application as long as my laptop is turned off. Now I'd like to know: (1) Is it possible to run the server application on a remote (physical) server, so that I don't need my laptop for that purpose? (2) If yes, do you have any suggestions where I could rent such a remote server? As I said, I'm just curious about how all that stuff works. I don't really something expensive.

• Artificial Intelligence - What to put in, or leave out, and what can be inferred?

  - by D Scott

  I was having a discussion with a coworker (while we were programming) about AI. We were talking about emotions/feelings and if you should choose to leave any out. I asked him, "Would you leave out racism or hate?" and if you did leave those out, what, if any, other emotions might lead to the AI learning the left out emotions or feelings. Should you PROGRAM in measures to stop the AI from learning those feelings? If you teach Love, does it need to know hurt? Or would it learn hurt? If it then knew Hurt would it connect it with Dislike, Hurt and Dislike could that then lead to some other non-programmed emotion? Such as hate? All while tele-commuting from home.

• How to version SQL Server schema using VS 2005?

  - by Mike

  I am new to C# programming and am coming to it most recently from working with Ruby on Rails. In RoR, I am used to being able to write schema migrations for the database. I would like to be able to do something similar for my C#/SQLServer projects. Does such a tool exist for the VS 2005 toolset? Would it be wise to use RoR migrations with SQL Server directly outside of VS 2005? In other words, I would handle all schema versioning using ActiveRecord:Migration from Rails but nothing else. If I do handle migrations outside of C# and VS 2005 with another tool, is RoR ActiveRecord:Migration the best thing to use or is there something which is a better fit?

• Mathematica quickie: About making cells Input cells by default.

  - by andrz

  I'm going through some lecture notes, Fundamentals of Mathematica Programming (see the .nb file there). I'd like to be able to do the exercises right there in the notebook; but for some reason I can't figure out how to make the default cell an Input cell. In other words, when I'm clicking in that notebook to create a new cell--in the exercises--the cell is by default a text cell. I'd like for it to be an Input cell so that I don't have to manually change it each time. Ideas?

• Can I reproduce Scala's behavior for == ?

  - by JPP

  In Programming in Scala, I can read that the == operator behaves as if it was defined like this: final def == (that: Any): Boolean = if (null eq this) {null eq that} else {this equals that} But there must actually be compiler magic to avoid null pointer exceptions, right? Is there any way for me to replicate this behavior with pure Scala; i.e., have an operator/method return one thing if the receiver is null and another one if it isn't? What I mean is an actual implementation of null eq this. I suppose I can write a "pimp" and then define the method on the wrapper class, but is there a more direct way to do this?

• Handling dynamic number of columns

  - by Whistle

  I'm developing a CMS of sorts, and I want to give my users the possibility of customizing the display. More precisely, I want to give them the ability to choose to display or hide the left column, the right column and/or the top div. The middle column cannot be hidden since this is where the actual content will show, whereas the other columns are for navigation or side menus. I've been looking for a way to make this as smart and flexible as possible. For now I'm using a MasterPage, but that seems to be too constraining. For instance, with MasterPage you need to add a ContentPlaceHolder control in every of your ASPX pages. What are the best practices in this area? I guess a simpler way of saying this would be "I want to create a template system over which I have complete control".

• Latest stream cipher considered reasonably secure & easy to implement?

  - by hythlodayr

  (A)RC4 used to fit the bill, since it was so simple to write. But it's also less-than-secure these days. I'm wondering if there's a successor that's: Code is small enough to write & debug within an hour or so, using pseudo code as a template. Still considered secure, as of 2010. Optimized for software. Not encumbered by licensing issues. I can't use crypto libraries, otherwise all of this would be moot. Also, I'll consider block algorithms though I think most are pretty hefty. Thanks.

• how to call functions/methods within CMS block or page?

  - by latvian

  Hi, We are trying to make all our blocks and pages static so that designer or anyone else can easily change the content or design of the website, however. There is a feature that uses our own custom module. So, the template that we want to make static is calling methods out of our custom block, for example, <!--some html code--> ..... <?php $this->helpMeBePartOfCMS(); ?> ..... <!--some html code--> How do i incorporate these method calls inside cms block or page? Thank you

• Basic CSS: having unordered list extend beyond container div?

  - by Tony

  Hi. It's been a bit since I've gotten really into CSS work, I'm trying to make a simple layout with a menubar. The idea is to have a container holding everything in the center of the screen and have a menubar (unordered inline list) that runs the full length of the screen but the list items to be contained in the container. See this pic for a visual example ps. I know this isn't true "programming", but this seemed like the most appropriate place to post this question. Let me know if there's a better /r/ for this to go.

• How to use default.ctp in cakephp

  - by Louis Stephens

  I just finished the "15 min Blog Post tutorial" included in the documentation for cakephp. I was asked for another tutorial to change the layout for first tutorial. However, I am fairly new to MVC programming/Cakephp and I have no real clue how to do so. Well, I know I need "default.ctp" placed in app/views/layouts/ and I presume I need to include to include my data? . . . I am really at a loss of what to do. I set up my default.ctp as I mentioned above, but when I go to localhost:9999/posts the layout is still the same. I guess I need to include a stylesheet (and if so, where?) I guess if someone can point me in the right direction to a beginner's guide to layout styling or how to use it I would greatly appreciate any help.

• Many-to-Many Relationship (with properties) in Google App Engine for Java

  - by rvandervort

  I understand from the official documentation on unowned relationships that the app must use sets of Key objects on either side of the relationship. This makes perfect sense. Coming from many years of RDBM-style programming, though, I'm pretty confused about how I can model properties of that relationship itself. For example, if I have entities Category and Entry in my many-to-many relationship and would like to persist a dateAdded property, or some other data that are only relevant when both sides of the relationship are known. I suppose it would be possible to create a third class : CategoryEntry that links the two, but this seems like a kludge. What is the proposed way to model this kind of situation ?

• doubt in - Function Objects - c++

  - by Eternal Learner

  I have a class class fobj{ public: fobj(int i):id(i) {} void operator()() { std::cout<<"Prints"<<std::endl; } private: int id; }; template<typename T> void func(T type) { type(); } My Doubt is if I invoke func like Method 1: func(fobj(1); the message I wanted to print is printed. I was always thinking I needed to do something like Method 2: fobj Iobj(1); // create an instance of the fobj class func(Iobj); //call func by passing Iobj(which is a function object) How does Method 1 work? I mean what exactly happens? and how is a call made to the operator() in class fobj ?

• Django: Is it possible to attach media files (css, javascript etc) to a View-class?

  - by mrmclovin

  I can't fins any information on how to define css or javascript files in a view like: class MyView(View): .... class Media: css = { 'all' : 'mystyle.css' } If you have a form you can do like: class MyForm(ModelForm): .... class Media: css = { 'all' : 'mystyle.css' } And then in the template you can print the files like; {{ form.media.css }} I like that Syntax very much and I like to keep the View-specific css files in the app-directory. Does anyone know if it's possible? Thanks!

• Get "2:35pm" instead of "02:35PM" from Python date/time?

  - by anonymous coward

  I'm still a bit slow with Python, so I haven't got this figured out beyond what's obviously in the docs, etc. I've worked with Django a bit, where they've added some datetime formatting options via template tags, but in regular python code how can I get the 12-hour hour without a leading zero? Is there a straightforward way to do this? I'm looking at the 2.5 and 2.6 docs for "strftime()" and there doesn't seem to be a formatting option there for this case. Should I be using something else? Feel free to include any other time-formatting tips that aren't obvious from the docs. =)

• The right way to setup VisualStudio 2010 for OpenCL

  - by LonliLokli

  what is the right way to setup VisualStuio 2010 for working with *.cl files? I have added *.cl under Tool/Text editor/File extensions and copied usertype.dat into the common7/ide folder, but VS underlines keywords like float4 or cross. Is it necessary to add some key in registry or can somebody propose a tutorial? Thanks in advance. PS i have already asked similar question old one question, but now i am looking explicit for a solution with vs2010. It is not bad, but really nerves and deflects me from programming tasks.

• C++ Boost bind value type {solved}

  - by aaa

  hello. I look in documentation and source code but cannot figure out how to get return value type of boost bind functor. I am trying to accomplish following: 35 template<typename T,size_t N, class F> 36 boost::array<typename F::value_type, N> make_array(T (&input)[N], F unary) { 37 boost::array<typename F::value_type, N> array; 38 std::transform(input, input + N, array.begin(), unary); 39 return array; 40 } where F can be bind functor. the above does not work because functor does not have value_type. for that matter, is there standard interface for unary/binary functor as far as return value. solution: it should be result_type. also equivalent defined are argument_type and first/second_argument_type for binary functions Thanks

• Guidance on using drop in DLLs

  - by Scott Chamberlain

  I have been giving the task to rewrite a internal utility in .net for my work. One of program requirements the new system has is have a dll that implements a set of interfaces and have the program call the DLL. Now this dll will be changed out a lot per deployment. My question is what is the best way to do it from a development standpoint? Do I add a template DLL (one that only has the interfaces but no implementation) to the project references like I would do any other dll that I would use. Or do I need to use somthing like this every time I want to use code from the dll? var DropIn = System.Reflection.Assembly.LoadFrom("DropInDll.dll"); var getActions = DropIn.GetType("Main").GetMethod("GetActions"); List<IAction> ActionList = (List<IAction>)getActions.Invoke(null, null);

• Why is iPhone 5 briefly Letterboxing and displaying Default.png in Cocos2d?

  - by The Learner

  I have [email protected] which loads fine. However, (on the actual device) after it shows the iPhone 5 then displays Default.png, in letter box mode. It then loads the 1136 × 640 px Title Screen - which is fine and what it's supposed to do. I'm using the default Cocos2d HelloWorld template. I haven't changed anything in the plist or otherwise. Any ideas? Why does it load the Default.png and how do you fix this? Thanks. In the IntroLayer we have -(void) onEnter if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone ) { background = [CCSprite spriteWithFile:@"Default.png"]; background.rotation = 90; } Which is why Default.png is showing up. How do you keep showing [email protected] if you are using the iPhone 5?

  Hello, I have 40 points with (x, y, z) coordinate in my iPhone app. For now I just NSLog them. But I'd like to display them in... 3D! How can I do that? Do I have to use openGL ES? What are the others possibilities (if there are any)? I've never used 3D in programming... is this a difficult thing to do? Thanks !

• facelet - nested <ui:insert>

  - by user321350

  I have multiple templates which differs with each other only by few containers. The most complex one contains superset of all containers used in all other one thus to avoid creating multiple templates I created the most complex one in following format some layout stuff (div and all) defining nested insert for each container and content. Now in client template based on what is needed I turn off container which is not needed as else if container is needed, just define content as doSomething Please let me know if you guys see any issues with this approach, any potential problem or alternate approach for similar scenario. thanks a lot.
