• Add valuable dynamic content to a mobile oriented (local) website, any suggestions?

  - by cesko80

  HI to all, I'm developing a mobile website containing some valuable dynamic content for people living in my city. I did find some useful informations that aren't available in a quick, light mobile format and I added to my site: teathers' programming, pharmacy shops open at night, twitter account embedding... have you got any other suggestion? I was thinking about facebook oauth to add some "social" feel, but I woluld like to avoid cloning fb information/features, just add some other cool addictive thing. I 'm using php for dynamic contents.

• How to calculate shot angle and velocity to hit a moving target?

  - by Guen

  I am developing a 2D Android game and I am making an aiming algorithm for AI projectiles to hit enemies either following a path, or free moving. At the moment it just calculates where the target will be after a distance and fires a projectile to meet it at that distance. Of course this means varying the projectile speed to meet the target. Does anyone have any tips for a simple-ish algorithm (optimal-ish) to calculate when the projectile needs to fire and where it needs to aim if it can only travel at a constant velocity? Say the projectile goes twice the speed of the target? The only way I can think of involves searching and seems quite large.

• Running the Ubuntu Kernel and OS on custom processor

  - by xupv5

  This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?

• Web Hosting Dublin [duplicate]

  - by user1543871

  This question already has an answer here: How to find web hosting that meets my requirements? 4 answers I am currently developing a site using laravel 4. I had intended on using Pagodabox for my hosting needs, however I now realize that they don't have servers outside of the US. So I'm just looking for some advice or recommendations? Can I still use Pagodabox with CloudFlare? Or would I be better of to use a provider with dedicated servers in Dublin? Such as Amazon bean stock. Any help greatly appreciated.

• Is there a name for a mini class that is not a struct?

  - by user1555300

  I have a couple of mini-classes that are not nested classes. They need to be passed around between different larger classes to use. In a way, they act like Tuples, storing fields in them. For example, [Serializable] public class TransformObject { public GameObject GameObj; public tk2dCameraAnchor Anchor; public ManagerTransform MTransform; } I have a few of them for my game I have been developing. They have to be classes, not struct because the Unity3d editor will not show in the inspector if so. I was just wondering if there is a official name for these kind of mini classes.

• Do I need a Point and a Vector object? Or just using a Vector object to represent a Point is ok?

  - by JCM

  Structuring the components of an engine that I am developing along with a friend (learning purposes), I came to this doubt. Initially we had a Point constructor, like the following: var Point = function( x, y ) { this.x = x; this.y = y; }; But them we started to add some Vector math to it, and them decided to rename it to Vector2d. But now, some methods are a bit confusing (at least in my opinion), such as the following, which is used to make a line: //before the renaming of Point to Vector2, the parameters were startingPoint and endingPoint Geometry.Line = function( startingVector, endingVector ) { //... }; I should make a specific constructor for the Point object, or there are no problems in defining a point as a vector? I know a vector have magnitude and direction, but I see so many people using a vector to just represent the position of an object.

• How is this paradigm/style called?

  - by McMannus

  I have the following situation: I'm developing an add-in for a UML modeling tool. The models that can be created by the user are stored inside the main application and a limited access to the models is given through its API. However, the add-in has a lot of callbacks for events that are triggered by the main application, when changes to the model occur by the user. Since the models are already stored once in the main application, I considered it not practicable to duplicate the models in the add-in, which leads to the fact that I have only behavior in the add-in, rather than having a state. This behavior is mainly expressed by static functions, that are organized in functional cohesive classes. The callbacks for the events have always references to the model elements relevant for the specifc event that ocurred. First, it seemed to me that this is a procedural style in general, but procedural style doesn't consider events/callbacks, so this boils down to the question. How is this programming style called?

• What book do you recommend for the OCAJP certification (1Z0-803) and OCPJP (1Z0-804) [on hold]

  - by Muhammad Gelbana

  I find completely contradicting reviews for the VERY same book on amazon and even some book writers are rewarding people for good reviews so basically most of the reviews are totally fake ! You can even figure it out from the reviewer name, which you'll similar to the writer's name and assume that they could actually be from the same country and the reviewer is just being helpful, to the book writer of course ! I can't make my mind for which book I should buy ! I only need a book or two that covers the Java associate and professional topics very well, not just an overview, I need a material that covers everything from A to Z. Even though I've been developing in Java for around 4.5 years but I must not know a detail or two. Would someone kindly shed some light on a good book based on actual experience with the book ? THANK YOU !

• How do you stay in touch with a programming language?

  - by Abijeet Patro

  I'll be starting work for the first time in the IT Industry on the 18th of this month. I'll be working mostly with Microsoft technologies such as C#.NET and MS Dynamic CRM. I spent the last year working with C++. Developing small applications to automate taks and organize my notes. During this time I have developed a good basic understanding of the language. My question is how do you guys stay in touch with a programming language that you love when you need to use something else at the office?

• Why do int when add up in java keeps on adding? [closed]

  - by Trycon

  I'm developing a game. I'm really new in java and researched google: why does an int when added, keeps on adding java Most of the times, it always adds even: STOP_DAMAGE+=1; Even sometimes, it subtract till negative. I'm annoyed. Sometimes it doesn't add too much. I do not understand. Here is my code: if(isPressed==true) { if(STOP_DAMAGE<=5) { if(WAIT_DAMAGE>=3000) { ENEMY_SHIP_HEALTH-=SHIP_DAMAGE_ENEMY; STOP_DAMAGE+=1; } } } for(;WAIT_DAMAGE>=3003;) { WAIT_DAMAGE-=WAIT_DAMAGE;//time is deducted } //WAIT_DAMAGE is a time int

• Learning to program styles? [closed]

  - by MrNewbProgrammer

  I'm a beginner programmer and I am currently developing an application of my own, just for the fun of it and learning to program. I'm building it from scratch, because I think that in this way I will learn the most. I have stumbled upon MVC's and CMS, CodeIgniter really got my attention, and the basic use is very straight forward. But I do not understand the inner workings completely. So I have decided that it might be better to just develop from scratch and maybe return to codeIgniter later, was that good decision? Would it be better to use CodeIgniter and learn from that?

• Where should I ask for feedbacks about web design? [closed]

  - by mariosangiorgio

  Possible Duplicate: Where can I get my website critiqued I am developing my personal website and I'd like to have feedbacks about its design. Is there any site/forum you would recommend me? I know that the best solution would be to hire a professional web designer and have him design my website, but I am also interested in understanding how to improve my design skills. Of course any recommended book, website, resource is more than welcome. I am not posting here the link to my home page because I think this Q/A site is more about web-development in general, but if you'd like to see my personal page and give some feedback I'll link it.

• getting Jomsocial profile fields [closed]

  I am developing a custom module in Joomla for searching user profile in many ways. I want country, state and some other custom profile fields to be searched. I have tried importing jomsocial library class of profile fields, but I have one issue. I have no object to pass into that function as a parameter. I have tried to fetch field values from database, but I got them in as a single string which is not filtered. Can anyone help me to use jomsocial library in custom module Joomla?

• Managing shots of the player

  - by Bitbridge

  I'm currently developing a 2D Jump'n'Run and the situation is the following: The player has different weapons he can collect and is then able to shoot the weapon's projectiles (laser, rockets, whatever). In my previous game (space shooter) I just had a manager class for all the weapon-shots, it stored them in a container and then updates and draws every single one. When the "shoot-event" occurred, the "ProjectileManager" was notified and it added the wanted projectile. The input for player action is handled in the player-class, so the player would have to know the manager to call the function of the manager. I also have a collisionManager, that checks for collisions between, for example, enemies and the projectiles and then notifies these objects. However, I somehow have the feeling, that I shouldn't use this approach and that there might be a better way to handle this. I know, the question is a bit vague, I'm pretty much just looking for input and ideas to improve my design.

• Organize a game set

  - by jncunha

  I'm developing a endless running game and I'm not really sure on how to make the set. The first approach was to make a BIG set like 10240x3072 pixels so that we have a nice portion of set. After having like 3 or 4 sets that go along with each other I would work on making their elements sequential and repeatable. However this is getting really heavy for the iPad 1 (it's running good in the iPad 2 and the New iPad) even though I'm splitting all the set in slices through Photoshop. For the implementation I'm using Cocos2D. Is there any better approach to make something like this but truly efficient for the iPad memory? Thank you.

• Game Database Connectivity Java

  - by The Kraken

  I'm developing a simple multi-player puzzle game in Java. Both players should be able to view the same game board on his own computer. Then, when one player makes an action in the game (ex. drags an object onto a coordinate space), the game's view should update automatically on the other computer's game screen. I'd like all this to happen over the internet, not requiring both computers to be on the same LAN connection. If I need to use SQL/PHP to accomplish this, I'm unsure how to design the database to accomplish something as simple as the following: Player A drags element onscreen Game sends coordinates of element to database/server Player B's computer detects a change to an item in the database Player B's computer grabs the coordinates of Player A's item Player B's machine draws onscreen elements at the received coordinates Could somebody point me in the right direction?

• How to start cross-platform desktop game development? [closed]

  - by Wamer

  I am interested in developing some 2d game since I have graduated and got some time to spare. I am looking for some advices where to start and with what. My main target platforms are Mac and Windows (later porting/rewriting/modifying for iOS, Android or WP7 is considerable). I need some advices about language I should choose, frameworks, engines and this kind of stuff. I gotta start somehow, but first of all I need to know how. Choosing good language with great framework/engine is key to ongoing successful game development I think.

• Notification framework for java

  - by rmarimon

  I'm in the process of developing a web application (java + jsp) that can send notifications to users. The user can subscribe to multiple events generated by the application and can choose to receive the messages associated with those events via multiple channels (email, sms, growl?, messenger); perhaps different messages through different channels; perhaps a daily message digest. Everything must be configurable by the user. Is there some framework that deals with this?
