• How auto load image work when an status is post to social website?

  - by huahsin68

  When posting a status update on social website like facebook.com and linkedin.com which contain an URL, it will automatically scan the images available on the particular website and put it at the front of the status update. May I know how this could be done if I would like to do the same for my web app? Which web framework (JSF, Richfaces, JQuery, ...) should I use in such development? Beside that, is there any pre-build features available in blogger.com or wordpress.com?

• How to I teach my artist to do arts for games?

  - by Holm76

  So my girlfriend is an artist and I'm a programmer and we often talk about joining talents and doing some small games or other fun stuff for the different popular platforms currently out. But because I haven't really done any serious games development yet I have a hard time explaining to her how she should create or package the assets she'd make so we always end up not doing nothing about it. What I'm mostly thinking about here is when doing frame by frame animation. I know sprite sheets are used for this kind of thing but then comes questions like frames per second and stuff like like that. Not program wise but art wise. Is there a reference site or sites out there that teach someone with the skills of art how to manage and arrange the assets in sprite sheets and other stuff in words that artists understand?

• Long running calculation on background thread

  - by SundayMonday

  In my Cocos2D game for iOS I have a relatively long running calculation that happens at a fairly regular interval (every 1-2 seconds). I'd like to run the calculation on a background thread so the main thread can keep the animation smooth. The calculation is done on a grid. Average grid size is about 100x100 where each cell stores an integer. Should I copy this grid when I pass it to the background thread? Or can I pass a reference and just make sure I don't write to the grid from the main thread before the background thread is done? Copying seems a bit wasteful but passing a reference seems risky. So I thought I'd ask.

• Updating query results

  - by Francisco Garcia

  Within a DDD and CQRS context, a query result is displayed as table rows. Whenever new rows are inserted or deleted, their positions must be calculated by comparing the previous query result with the most recent one. This is needed to visualize with an animation new or deleted rows. The model of my view contains an array of the displayed query results. But I need a place to compare its contents against the latest query. Right now I consider my model view part of my application layer, but the comparison of two query result sets seems something that must be done within the domain layer. Which component should cache a query result and which one compare them? Are view models (and their cached contents) supposed to be in the application layer?

• Ubuntu 12.04 and Realtek Wireless Card Incompatible

  - by Tim

  Quick background: I installed Linux Ubuntu 12.04 on a Dell Inspiron 3520 after uninstalling Windows 8. A friend suggested to do this as opposed to buying a laptop with Linux pre-installed. Everything except the wireless card works. When I load up the laptop, I see a wireless animation as if it's trying to locate the wireless connection (for a while, then it goes blank), but no connections appear under the wireless option (under "Edit Connections" then "Wireless"). What I've tried: - Doing ndiswrapper. Failed. - Installing a few kernels for realtek. Failed.

• What is the best shopping cart or implementation for unlimited users posting unlimited products? [closed]

  - by Matt

  I've been working with x-cart much lately, and I was thinking about using it for a much larger site, but I don't know if it can handle what I'm looking for. I need a platform or strategy that can allow for as many users as possible where each can post multiple products (hopeful up to a hundred, but that's less important), but in their own private catalogs. So what am I looking for? With x-cart, I'm used to customizing it with jquery, smarty, and php, so I can handle that much.

• 3D game engines for XNA games

  - by Jenko

  Before I start development of an XNA game, I need to choose a 3D game engine to develop upon. Is this belief unfounded? Does XNA have basic object transformation, lighting and mesh/texture importing functionality by which you can develop a decent 3D side-scrolling game? Chances are I'm going to need a 3D engine such as Torque X to handle most of the special effects, animation and sound for me. What are the engines that you recommend building an XNA game with? What work reliably in your experience? Is XNA alone enough? do you have repositories of code that work directly with XNA to create effects and other game environments with sunlight, fog and rain?

• New Features Of WordPress 3.3 You Must Know

  - by Gopinath

  After months of beta testing, WordPress 3.3 version is going to be released at the end of this month. There are several new features packed in the new version and few of them are going to excite WordPress admins. In this post we are going to discuss about the exciting new features. 1.

Now you can upload multiple files by just dragging & dropping, instantly resize  the images and filter files by their type. The media upload sports a brand new look WordPress adopted the Pupload plugin to power its media uploader component and it’s written by the same team who created the popular TinyMCE editor plugin. 2. Improved Admin Bar(Toolbar) The admin bar or newly called toolbar has got handful of makeovers. The not so much used items like Search box and other elements are removed to make sure that the bar is not clumsy. The user menu and the related options are moved to the right like how we see in Google’s user bar. Also there are few changes to the colour of the bar to make it more eye friendly. 3. Fly out Admin Menus All the left side bar menus of WordPress admin are now sports a fly out menu style to save a click. In the previous versions if you want to access a sub menu on the left side bar, you need to first click on the category and then choose the menu item from the expanded list. Now on just mouse over you will see a flyout of menu items. 4. Adaptive Admin – Layout Auto Adjust To Fit Various Devices If you own an iPad or any other so called tablets then you are going to love this feature.

• I need advice on creating animal 3D walk cycles in XNA

  - by Zetar

  I want to purchase a number of 3D models from TurboSquid and animate them in an XNA game. I wrote a lot of games from 1985-1999 and have recently become involved with XNA. Now I would like to port one of my old games to the XBOX. I do have a background in 3D animation; but that was years ago. What is the current method for animating a walk cycle with a 3D model and using it inside XNA? Is there a book, software or a tutorial that you can recommend? Thanks in advance and sorry for such a broad and currently naive question.

• Where can I find resources for RPG Character Sprites? [closed]

  - by IcySnow

  I'm developing a turn-based 2D RPG game. Everything's going fine except the lack of characters' sprites such as moving, attacking animation, etc.... By characters I mean both human-like and monster-like creatures. Is there a website providing sprites for free? Or a program (free or paid, whichever is fine) which will let me create sprites from scratch and automatically generate the images? I tried my best to search for one but the best I've managed to find so far is http://spriters-resource.com/. However, is there something else similar and better out there?

• Should iOS games use a Timer?

  - by ????

  No matter what frameworks we use -- Core Graphics, Cocos2D, OpenGL ES -- to write games, should a timer be used (for games that has animation even when a user doesn't do any input, such as after firing a missile and waiting to see if the UFO is hit)? I read that NSTimer might not get fired until after scheduled time (interval), and CADisplayLink can delay and get fired at a later time as well, only that it tells you how late it is so you can move the object more, so it can make the object look like it skipped frame. Must we use a Timer? And if so, what is the best one to use?

• Which Git-based MIS to track workflow like Trac/Redmine but on console minimastically?

  - by hhh

  Definitions MIS = management information system Some list about console based solutions here and some GUI-hacks here. Been fed up to install all those dependencies and no make -files with GUI -things so which console-based MIS would you suggest for a game-development team with graphical -repo, animation -repo, code -repo, stories -repo, etc ? P.s. I do use Git -submodules and the reason for repo -fragmentation is due to roles and size, certain repos such as graphic -repos tend to be quite large so better to keep them separate. Perhaps useful to readers interested about this http://stackoverflow.com/questions/5881578/trac-vs-redmine https://github.com/jchris/sofa

• How can I improve the workflow between developer and designer with Expression Blend?

  - by Amenti

  We use WPF and Expression Blend 4. I'm trying to improve our workflow by tutoring one of our designers to use it for styling and animation. Slowly but surely I get the impression Blend in itself is to technical for the designer in question. I myself use it only occasionally (it's great for Visual States for instance) because a lot of things are easier done in code or not possible at all in Blend alone. It seems a developer with design experience is a lot more productive with it than a sole designer. Are there any good resources or advice as to how I can improve this workflow?

• How to create a Raining Effect(Particles) on Android?

  - by user19495

  I am developing a 2d android strategy game, it runs on SurfaceView, so I can't(or can I?) use LibGdx's particle system. And I would like to make a raining effect, I am aiming for something like this( http://ridingwiththeriver.files.wordpress.com/2010/09/rain-fall-animation.gif ), I don't need the splash effect in the end (although that would be superb, but probably would take up a lot of system resources). How could I achieve that raining effect? Any ideas? Thank You a lot in advance!

• User management system and DELETE action - usability

  - by šljaker

  I'm working on User Management System in ASP.NET MVC3. Administrator/Editor can search, insert, update and delete other users from the system. What should I do when admin/editor clicks on Delete user link? Should I redirect him to new yes/no confirmation page or display some jquery popup window? Should I then redirect him to the home page and display message 'The user has been successfully deleted from the system', or simple redirection should be just fine?

• After reinstalling ATI graphics drivers, my keyboard and mouse aren't working anymore

  - by Lifelike27

  On Ubuntu 11.04 I tried to install the open source drivers for my laptops ATI Mobility Radeon 5470M but I messed that up a bit and lost xserver. Now I've managed to solve that problem with this and by downloading the ATI proprietary drivers and install those manually. Now, when Ubuntu loads up I get to the login screen but I can't use my mouse or my keyboard (usb keyboard and mouse doesn't work either). If I use the recovery console, then login with that and then run 'startx'. I can login fine (though Unity doesn't show, the graphics seem to be working because it shows the fading animation of libnotify), but I can't type or move my mouse.

• Should I drawing directly on CCLayer or CCSprite?

  - by einverne

  Now I am a little confused in my cocos2d-x cpp project. I want to draw lines with user's finger touch. Following the screenshot of a CCScene: In the screen, there are two squares. I want show an animation in the first square and let the second one draw lines with user touch. Now these two squares are CCSprite. And I can draw dots in the second one on the CCLayer. But I am little confused that I should draw lines on the Sprite or on the Layer. Or are there other ways to organize the code?

• Phone number mask in a DataView WebPart (DVWP)

  - by PeterBrunone

  This came up today on the [sharepointdiscussions] list.  A user needed to display a read-only field in a phone number format; it's pretty simple, but it may be just what you need.Assuming your list item contains a field called "Phone Number" (with a space), the following XPath will give you a number in the classic US telephone format: <xsl:value-of select="concat('(',substring(@Phone_x0020_Number,1,3),')',substring(@Phone_x0020_Number,4,3),'-',substring(@Phone_x0020_Number,7,4))" /> If you need to mask an input, try this jQuery solution.

• lead capture apps

  - by Steve

  I'd like to build a lead capture website, where a visitor is required to enter their name and email address in order to receive a free report for download. Do you know of an app which will let me store captured information in a database, and present the download link to them after registering? I guess this can all be accomplished using a contact form script with database integration and jquery confirmation message.
