  • Component based game engine design

    - by a_m0d
    I have been looking at game engine design (specifically focused on 2d game engines, but also applicable to 3d games), and am interested in some information on how to go about it. I have heard that many engines are moving to a component based design nowadays rather than the traditional deep-object hierarchy. Do you know of any good links with information on how these sorts of designs are often implemented? I have seen evolve your hierarchy, but I can't really find many more with detailed information (most of them just seem to say "use components rather than a hierarchy" but I have found that it takes a bit of effort to switch my thinking between the two models). Any good links or information on this would be appreciated, and even books, although links and detailed answers here would be preferred.

  • Jquery.get() not returning any data

    - by David Waters
    Hi I am trying to scrape other people web pages (for the forces of good not evil). I am currently trying to do this with javascript/jquery from with in a browser. I am finding that the no data is returned from the jquery.get() success call back function. My code. $.get('http://www.google.co.uk/', function (data, textStatus, XMLHttpRequest){ alert("status " + textStatus); alert('data:' + data); window.data=data; window.textStatus=textStatus; window.httpReq = XMLHttpRequest}); In my mind this should simply do a get on google store the data in window.data and we are all good. What happens is we get textStatus == success and data == "". the status on the XMLHttpRequest is 4(success). I have looked at the network traffic using a transparent proxy (Charles) and everything looks find there http status 200 plenty of data being returned. I am running this just from the Firebug console in Firefox. Any ideas?

  • Problem making system calls with PHP scripts

    - by mazin k.
    I have the following PHP script: <?php $fortune = `fortune`; echo $fortune; ?> but the output is simply blank (no visible errors thrown). However, if I run php -a, it works: php > echo `fortune`; Be careful of reading health books, you might die of a misprint. -- Mark Twain php > Am I missing a config directive or something that would cause this? Edit: So, I tried running my script using $ php-cgi fortunetest.php and it worked as expected. Maybe the issue is with Apache2?

  • "cloud architecture" concepts in a system architecture diagrams

    - by markus
    If you design a distributed application for easy scale-out, or you just want to make use of any of the new “cloud computing” offerings by Amazon, Google or Microsoft, there are some typical concepts or components you usually end up using: distributed blob storage (aka S3) asynchronous, durable message queues (aka SQS) non-Relational-/non-transactional databases (like SimpleDB, Google BigTable, Azure SQL Services) distributed background worker pool load-balanced, edge-service processes handling user requests (often virtualized) distributed caches (like memcached) CDN (content delivery network like Akamai) Now when it comes to design and sketch an architecture that makes use of such patterns, are there any commonly used symbols I could use? Or even a download with some cool Visio stencils? :) It doesn’t have to be a formal system like UML but I think it would be great if there were symbols that everyone knows and understands, like we have commonly used shapes for databases or a documents, for example. I think it would be important to not mix it up with traditional concepts like a normal file system (local or network server/SAN), or a relational database. Simply speaking, I want to be able to draw some conclusions about an application’s scalability or data consistency issues by just looking at the system architecture overview diagram. Update: Thank you very much for your answers. I like the idea of putting a small "cloud symbol" on the traditional symbols. However I leave this thread open just in case someone will find specific symbols (maybe in a book or so) - or uploaded some pimped up Visio stencils ;)

  • How to set focus to a textbox on page load event

    - by Kalpana
    I am trying to set focus to the text box on page load event. I tried many solutions by referring the element id, but couldn't able to focus the element. Later when I inspect the element using firebug I found for the same element the id changes in different execution. I am looking for the simplest solution using javascript or jquery to achieve this <h:form id="form"> <rich:dataTable value="#{books}" var="book"> <ui:repeat value="#{authors}" var="author"> <h:inputText value="#{author.name}"/> </ui:repeat> </rich:dataTable> </h:form>

  • Notification Email Best Practices--From Server Setup to Programming

    - by Andrew Wagner
    All, I'm in the process now of building a SaaS tool that allows network admins to generate notification emails to the members of the end-users of our platform (among many many other things). I'm running into a bit of an "out of my expertise" wall, as I know there are a lot of variables involved with configuring an application that can: Run in a distributed way via load balancing and still-- Leverage a single mail server for sending notification emails Process unsubscribe requests Avoid any ISP blacklisting in the process. If anyone has the time and has done this before, I'd love if you could walk me through the A-Z of best practices both from a configuration perspective and an execution perspective for generating these emails (anything from necessary DNS settings to ideal SMTP setup and configuration) Currently, our application generates email via Google Apps using the PHPMailer class. While this works well, it doesn't queue messages (potential for timeout problems if any of our clients amass a very large list of end-users), and Google limits the amount of allowed generated email messages to 500/day. I know this is a lofty question, but any guidance you could provide would be smashing and a big help as we work through this hurtle in our beta development stage. Thanks!

  • Embedding an offline Dashcode application in a UIWebView in an iPhone application

    - by Nimrod
    In order words, can anyone tell me the basics of how to create a "hybrid" iPhone application? I want to load the web content (the Dashcode app itself) from the native application's application bundle. I've gotten this to partially work, but some content won't display and it otherwise seems like Dashcode is assuming a certain Safari environment or something that I don't seem to have in my UIWebView. Can anyone provide a link to some sample code that embeds a Dashcode project into a cocoa touch Xcode project? (I did search around Google for a bit trying to find something and I failed to come up with anything worthwhile, except for some books that I might eventually buy if the approach seems worthwhile.)

  • Some solid OOP criticism?

    - by Bubba88
    Hi! I want to ask you to provide me with some articles (maybe books), which you possibly have found very convincing criticising the OOP methodology. I have read some in the WWW on this topic and I didn't really find a 'definitive demotivator'. It's not much about my personal attitude to the OOP, but I really would like to have something constructive, rigorous foundation for any kind of discussion and just abstract thinking. You can post some original research too, but please be very constructive (as my personal request). Thank you very much!

  • Algorithms for City Simulation?

    - by anon
    I want to create a city filled with virtual creatures. Say like Sim City, where each creature walks around, doing it's own tasks. I'd prefer the city to not 'explode' or do weird things -- like the population dies off, or the population leaves, or any other unexpected crap. Is there a set of basic rules I can encode each agent with so that the city will be 'stable'? (Much like how for physics simulations, we have some basic rules that govern everything; is there a set of rules that governs how a simulation of a virtual city will be stable?) I'm new to this area and have no idea what algorithms/books to look into. Insights deeply appreciated. Thanks!

  • How to save image to iphone's AddressBook using SDK API ?

    - by apple.dev
    My purpose is to process one image from image library, and save this image directly to one person record (i,e, "Tom" ), which is selected from AddressBook, I can see the new image replace Tom's previous image, but I can not save it to AddressBook. I implemented delegate ABPeoplePickerNavigationControllerDelegate, and using following logics, but whatever I tried, modified records can not be saved to address books. Any clues or suggest ? Thanks ABAddressBookRef addressBook= ABAddressBookCreate(); CFErrorRef error = NULL; BOOL wantToSaveChanges = YES; ABRecordSetValue(person, kABPersonFirstNameProperty, @"Shi", &error);//, &error) NSData * dataRef = UIImagePNGRepresentation(cellImage); ABPersonSetImageData(person, dataRef, &error); if (ABAddressBookHasUnsavedChanges(addressBook)) {\ NSLog(@"need to save "); if (wantToSaveChanges) { ABAddressBookSave(addressBook, &error); } else { ABAddressBookRevert(addressBook); } }else { NSLog(@"no changes"); } if (error != NULL) {/*... Handle error. ...*/ NSLog(@"error happened here " ); } CFRelease(addressBook);

  • JSON-RPC and Json-rpc service discovery specifications

    - by Artyom
    Hello, I'm going to implement JSON-PRC web service. I need specifications for this. So far I had found only one resource that can be called as real specifications: JSON-RPC 1.0 http://json-rpc.org/wiki/specification Proposal of JSON-PRC 2.0: http://groups.google.com/group/json-rpc/web/json-rpc-2-0 (why is it on google groups?) However I've seen that JavaScript frameworks like Dojo actively use JSON-RPC SMD Service Mapping Description proposal But it requires JSON Schema specifications, but it redirects to incorrect URL as reference. So far I had found following: http://tools.ietf.org/html/draft-zyp-json-schema-02 And it is still draft... Can anybody point me to some actual specifications... At least something official updated? Because it looks like that implementing JSON-RPC 1.0 as is may be not enough, at least for frameworks like Dojo. Or am I wrong? Questions: Would implementation of JSON-RPC 1.0 specifications be enough to provide JSON-RPC service for most of modern clients, and how many clients there (if at-all) that actually support beyond JSON-RPC 1.0 capabilities (SMD, Schema, 2.0)? Because it looks like that JSON-RPC 1.0 is only one that has official specifications (and not draft) If I should implement SMD, or it is recommended can somebody point to official, most recent specifications of Json Schema and Service Mapping Description or links I found are really "the specifications?" Are JSON-RPC 2.0, SMD and JSON-Schema drafts stable enough to implement them? Note: do not suggest existing JSON-RPC service implementations. Anybody?

  • ASP.NET MVC GoogleBot Issues

    - by Khalid Abuhakmeh
    I wrote a site using ASP.NET MVC, and although it is not completely SEO optimized at this point I figured it is a good start. What I'm finding is that when I use Google's Webmaster Tools to fetch my site (to see what a GoogleBot sees) it sees this. HTTP/1.1 200 OK Cache-Control: public, max-age=1148 Content-Type: application/xhtml+xml; charset=utf-8 Expires: Mon, 18 Jan 2010 18:47:35 GMT Last-Modified: Mon, 18 Jan 2010 17:07:35 GMT Vary: * Server: Microsoft-IIS/7.0 X-AspNetMvc-Version: 2.0 X-AspNet-Version: 2.0.50727 X-Powered-By: ASP.NET Date: Mon, 18 Jan 2010 18:28:26 GMT Content-Length: 254 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title> Index </title> </head> <body> </body> </html> Obviously this is not what my site looks like. I have no clue where Google is getting that HTML from. Anybody have an answer and a solution? Anybody experience the same issues? Thanks in advance.

  • Slimbox 2 Plugin, jQuery Flickr, and IE8

    - by Nick H.
    Hello, I am currently developing a site that I make use of two jQuery plugins: Flickr jquery plugin (http://code.google.com/p/jquery-flickr/) Slimbox (http://code.google.com/p/slimbox/) The first plugin is used to pull in flickr photos from a specific account. These photos are displayed as thumbnails on the page. I am then using the second plugin to display larger views of these images. Because the flickr photos are fetched when the page loads, I am calling the Slimbox 2 function like this: $(document).ready(function() { $("#Flickr").flickr(); //Call Flickr plugin $(window).bind('load', function() { $("#Flickr a").slimbox();//Call Slimbox2 }); }); On first testing this seemed to have worked perfectly. I tested multiple versions of FireFox, IE7, IE6, and Safari. Everything is great. However, the Slimbox lightbox effest does not work in IE8. However, if I put IE8 into compatibility mode, everything works as expected. I would like to avoid forcing compatibility mode. There are no javascript errors and I am at a loss for testing. Here is a link to a sample: http://www.njhall.com/JRMcCourt-Builders/index.html#ourwork Any advice would be greatly appreciated. Thanks Nick

  • why do game engines prefer static libraries over dynamic link libraries

    - by numerical25
    I've been reading a few gaming books. And they always prefer to create the engine as a static library over dynamic link. I am new to c++ so I am not highly knowledge when it comes to static libraries and dynamic link libraries. All I know is static libraries increase the size of your program, where DLL link libraries are loaded as you need them within your program. [edit] I've played games where it almost seemed they used DLL's to load in sound, lighting, and what not all individually. as the level was loading up. cause you don't necessarily need that when your at the game menu.

  • First TDD, Simple 2-tier C# Project - what do I unit test?

    - by Joel
    This is probably a stupid question but my googling isn't finding a satisfactory answer. I'm starting a small project in C#, with just a business layer and a data access layer - strangely, the UI will come later, and I have very little (read:no) concept / control over what it will look like. I would like to try TDD for this project. I'm using Visual Studio 2008 (soon to be 2010), I have ReSharper 5, and nUnit. Again, I want to do Test-Driven Development, but not necessarily the entire XP system. My question is - when and where do I write the first unit test? Do I only test logic before I write it, or do I test everything? It seems counter-productive to test things that have no reason to fail (auto-properties, empty constructors)...but it seems like the "No new code without a failing test" maxim requires this. Links or references are fine (but preferably to online resources, not books - I would like to get started ASAP). Thanks in advance for any guidance!

  • Resources for rails widget creation

    - by Kenji Crosland
    My rails app is about to go live and I'm trying to figure out how to create a widget based on data on the site. My Javascript is not too hot--limited to the O'reilly head first book on JS. I can read simple Javascript okay but when it comes to writing it I'm a little lost. That said, I hope to roll out a widget, maybe a wordpress plugin too soon after my app is launched. Does anyone know of any rails plugins, javascript templates, tutorials or books that can get me going? I did ask a similar question before here: But my limited knowledge of JS kept me from implementing the suggested answer properly.

  • Problem adding Contact with new API

    - by Mike
    Hello, I am trying to add a new contact to my contact list using the new ContactContract API via my application. I have the following method based on the Contact Manager example on android dev. private static void addContactCore(Context context, String accountType, String accountName, String name, String phoneNumber, int phoneType) throws RemoteException, OperationApplicationException { ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>(); //Add contact type ops.add(ContentProviderOperation.newInsert(ContactsContract.RawContacts.CONTENT_URI) .withValue(ContactsContract.RawContacts.ACCOUNT_TYPE, accountType) .withValue(ContactsContract.RawContacts.ACCOUNT_NAME, accountName) .build()); //Add contact name ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI) .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0) .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE) .withValue(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME, (!name.toLowerCase().equals("unavailable") && !name.equals("")) ? name : phoneNumber) .build()); //Add phone number ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI) .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0) .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE) .withValue(ContactsContract.CommonDataKinds.Phone.NUMBER, phoneNumber) .withValue(ContactsContract.CommonDataKinds.Phone.TYPE, phoneType) .build()); //Add contact context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops); } In one example I have the flowing values for the parameters. accountType:com.google accountName:(my google account email) name:Mike phoneNumber:5555555555 phoneType:3 The call to the function returns normally without any exception being thrown however the contact is no where to be found in the contact manager on my phone. There is also no contact with that information on my phone already. Does anyone have any insight into what I might be doing wrong?

  • How do I turn off accelerometer input for my flipside view

    - by user308050
    I have an iPhone 3.1.3 app which has only 2 methods of input in its main view. It has an info button to switch to a flipside view, and the only other input it takes in the main view is accelerometer movement. I want to switch off the accelerometer input when in the flipside view but haven't been able to find out how. I have the main view controller set as an accelerometer delegate, but did not do the same for the flipside view controller, though I suspect that it inherited it from the main view controller. I am really new to xcode and objective c, I have been reading these forums and a couple of developer books, but if anyone has any tips on other good places to look, please let me know.

    I am creating a vBulletin forum community called: wehypnosis We purchased the vBulletin version 4.0 CMS and the SEO plugin. Im used to designing and building templates for drupal, wordpress and joomla. All of which have great documentation and many tutorials built by the community. But vBulletin although claimed as the best forum software on the internet, is missing any form of documentation worth reading. The only thing I can find to help me rebuild this monster is www.vbulletin.com/docs/ Does anyone know of a set of tutorials or any documentation which would help me: Configure a good solid working version? Give detailed instruction on how to build themes for vBulletin? Drupal has a mountain of great books and resources. Does vBulletin?

  • Dashcode development for iPhone resources

    - by gonso
    I've been developing web applications and iPhone applications for years. Now I want to create a web application oriented to the iPhone browser. I willing to use Dashcode, since it seams to have tons of cool features that make my web app look like an native iPhone app. The problem I face is twofold: On one side I don't know it Dashcode development will allow me to do all I want (session control, runtime datasources, etc); on the other side I'm having a hard time finding good documentation, tutorials and books on Dashcode programing for the iPhone. Looks like 90% of the links out there are for Dashcode widgets. Can you advise me on the best resources to learn Dashcode (for mobile Safari) programming? Thanks Gonso

  • How to structure VB.NET windows forms applications

    - by Jon
    What is the best way to structure a VB.NET windows forms application so that code can be reused and the app can be extended easily. I used to create lots of new forms. This lead to lots of repeated code and forms which did similar things. Now, for forms which do similar jobs, such as view/edit/delete items from a specific db table, I create a form with the required controls, have the form create an instance of a class with params such as a collection of the controls and a string containing the db table name. Then the individual controls call functions of the class. Advanced forms will inherit and extend this basic form class. 1) Has there already been work done in this area? 2) Are there books / articles available which discuss the options available on this topic? Thanks!

  • HTML5 web storage: can different websites overwrite each other’s data on a user’s computer?

    - by Deepak Mahalingam
    I have a few questions regarding the concept of HTML5 storage. I went through the w3c specification, books and tutorials on the same, but still I am a bit unclear about certain concepts: Assume that I access Website A. Some JavaScript runs in my browser that sets a key value pair, say ('username','deepak'). Then I access Website B which also adds a key,value pair in the localstorage as ('username','mahalingam'). How will they both be differentiated? Will Website B override the value set by website A in my localstorage? How can we ensure that a website would not erase all of my localstorage?
