  • Native mobile app development - how do I structure my user stories?

    - by richsage
    I'm about to start on a project which will involve developing prototype native mobile apps (iOS and Android initially) as well as a web-based admin interface and an API for these apps to communicate with. We've got a list of stories already drafted up, however a lot of them are in the format: As a mobile user I want to be able to view a login screen so that I can sign into the app If this were targeted for a single platform, I wouldn't see a problem. However, since we're targeting multiple platforms, I'm not sure whether these should now be duplicated eg "As an Android user" or similar. This seems like duplication, but it's work that will need to be completed separately for each platform. This is the first mobile project we've gone native on - previously it was Phonegap and we lumped all stories in under "As a mobile user". Since essentially this was a web-based app wrapped in native code, this didn't present too much of an issue, but I'm conscious that wholly-native apps are a different ballgame!

  • Branding Changes for Java EE6

    - by Paul Sorensen
    Hi Everyone, As we move the Java EE6 exams from beta to production, you may notice that we have made a slight change in the branding. Instead of being branded Oracle Certified Professional (OCP), these new credentials are now branded Oracle Certified Expert (OCE). One area where we use the Expert brand is for credentials where the technology is advanced or broader than the path based credential requires. Some are high-end add-on certifications, and others have significant additional technological breadth. In these cases, the Expert brand is an indication that someone is tested in more advanced or in-depth skills - beyond the traditional path-based certification. A few examples are RAC Expert for DBAs, or SQL Expert - also for DBAs. Because (1) all of the Java EE6 credentials require that candidates become certified first in Java SE6, and (2) many people earn more than one Java EE credential, we felt that the Expert branding would be more appropriate. Thanks,

  • Could I be going crazy with Event Handlers? Am I going the "wrong way" with my design?

    - by sensae
    I guess I've decided that I really like event handlers. I may be suffering a bit from analysis paralysis, but I'm concerned about making my design unwieldy or running into some other unforeseen consequence to my design decisions. My game engine currently does basic sprite-based rendering with a panning overhead camera. My design looks a bit like this: SceneHandler Contains a list of classes that implement the SceneListener interface (currently only Sprites). Calls render() once per tick, and sends onCameraUpdate(); messages to SceneListeners. InputHandler Polls the input once per tick, and sends a simple "onKeyPressed" message to InputListeners. I have a Camera InputListener which holds a SceneHandler instance and triggers updateCamera(); events based on what the input is. AgentHandler Calls default actions on any Agents (AI) once per tick, and will check a stack for any new events that are registered, dispatching them to specific Agents as needed. So I have basic sprite objects that can move around a scene and use rudimentary steering behaviors to travel. I've gotten onto collision detection, and this is where I'm not sure the direction my design is going is good. Is it a good practice to have many, small event handlers? I imagine going the way I am that I'd have to implement some kind of CollisionHandler. Would I be better off with a more consolidated EntityHandler which handles AI, collision updates, and other entity interactions in one class? Or will I be fine just implementing many different event handling subsystems which pass messages to each other based on what kind of event it is? Should I write an EntityHandler which is simply responsible for coordinating all these sub event handlers? I realize in some cases, such as my InputHandler and SceneHandler, those are very specific types of events. A large portion of my game code won't care about input, and a large portion won't care about updates that happen purely in the rendering of the scene. Thus I feel my isolation of those systems is justified. However, I'm asking this question specifically approaching game logic type events.

  • Access Token Verification

    - by DecafCoder
    I have spent quite a few days reading up on Oauth and token based security measures for REST API's and I am currently looking at implementing an Oauth based authentication approach almost exactly like the one described in this post (OAuth alternative for a 2 party system). From what I understand, the token is to be verified upon each request to the resource server. This means the resource server would need to retrieve the token from a datastore to verify the clients token. Given this would have to happen upon every request I am concerned about the speed implications of hitting a datastore like MySQL or NoSQL upon every request just to verify the token. Is this the standard way to verify tokens by having them stored in a RDBMS or NoSQL database and retrieved upon each request? Or is it a suitable solution to have them cached (baring in mind that we are talking millions of users)?

  • Remote Desktop advice

    - by spoon16
    Coming from Windows, so that is what my expectations are based on. I have a Ubuntu desktop edition instance running as a virtual machine on a server. I would like to use it as my primary open source dev environment but the VNC tools I have used don't seem to be as rich as "Remote Desktop Connection" in Windows. The two things that are missing for me: connecting/logging into a non-console user sessions dynamically resizing the graphical resolution based on the size of the remote desktop window device sharing (USB devices plugged into client shared with remote) Is there an appropriate client that I can run on Windows to connect to my ubuntu dev instance that provides these capabilities?

  • How to Add a Google Call Widget to Any Web Page

    - by babblescribe
    Adding a Google Call Widget to your website or blog allows visitors to contact you using your Google Voice number. The widget provides an easy and cost-effective way to provide live customer support without the customer knowing your real number. The Call Widget works using Google Voice to first call the number the customer types into the widget form. Once connected, the user is prompted to connect to the number you have configured the widget to call. Google voice connects the two numbers and you are talking away in an instant.How To Encrypt Your Cloud-Based Drive with BoxcryptorHTG Explains: Photography with Film-Based CamerasHow to Clean Your Dirty Smartphone (Without Breaking Something)

  • Jersey 2.0 Milestone 2 Now Available

    - by arungupta
    Jersey 2.0 milestone 2 is now available. It builds upon the first milestone and adds several new features such as server-side asynchronous processing, server-side content negotiation, improved JAX-RS parameter injection, and several others. The REST endpoints can be published on Java SE HTTP Server, Grizzly 2 HTTP container, and some basic Servlet-based deployments. It also provides HTTPURLConnection-based client API implementation. Read about these and more about what's new in Marek's detailed post. Of course this is also the future reference implementation for JAX-RS 2.0. Feel like trying it out? Simply go to Maven Central (of course none of this is production quality at this point). The latest JAX-RS Javadocs and Jersey 2.0 API docs are good starting points to explore. And provide them feedback at [email protected].

  • What technology(s)would be suitable for the front end part of a Java web game?

    - by James.Elsey
    As asked in a previous question, I'm looking to create a small MMO that will be deployed onto GAE. I'm confused about what technologies I could use for the user interface, I've considered the following JSP Pages - I've got experience with JSP/JSTL and I would find this easy to work with, it would require the user having to "submit" the page each time they perform an action so may become a little clumsey for players. Applet - I could create an applet that sits on the front end and communicates to the back end game engine, however I'm not sure how good this method would be and have not used applets since university.. What other options do I have? I don't have any experience in Flash/Flex so there would be a big learning curve there. Are there any other Java based options I may be able to use? My game will be text based, I may use some images, but I'm not intending to have any animations/graphics etc Thanks

  • Implementing scrolling buttons in android

    - by Twirling Hearth
    I want to create an Android app in which the buttons scroll up or down the screen, kind of like a "wheel", so that when the "last" button is reached, it is simply followed seamlessly by the first one. I would want it to look something like the Price Is Right wheel. (This video at 0:12.) I want the first round of buttons to be presented for the user to tap the screen and make his choice, which would lead to a second round of buttons based on the first choice, and a third round based on the second choice. I've done a number of different google searches, but nothing so far. Any ideas?

  • Organizing your Data Access Layer

    - by nighthawk457
    I am using Entity Framework as my ORM in an ASP.Net application. I have my database already created so ended up generating the entity model from it. What is a good way to organize files/classes in the data access layer. My entity framework model is in a class library and I was planning on adding additional classes per Entity(i.e per database table) and putting all the queries related to those tables in their respective classes. I am not sure if this is a right approach and if it is then where do the queries requiring data from multiple tables go? Am I completely wrong in organizing my files based on entities/tables and should I organize them based on functional areas instead.

  • game programming career, vc++ reference and future of it [closed]

    - by Pappu Bacha
    1) I have quite a lot of interest in game programming and I (to my thought) am quite good at programming skills, I have developed some console based animations and text based animation games (like copter-it, snake, and a music visualization), should I invest in game programming? I have 2 years at college left. 2) If I am to pursue a career in game programming, and I select to go only with c++ and DirectX, is it enough? is assembly language necessary? 3) is Visual C++ or MFC dead? should I invest in it or not? 4) I am unable to find any reference book for Visual C++ 2008 or later (just like C++ the complete reference book) I need a book that covers the basic fundamentals and covers the most of the libraries etc.

  • CLI Shared Hosting Management (scripts to manage web users and hosts) [on hold]

    - by aularon
    I am currently administrating two servers: first one has no control panel, I am creating directory structure, setting permission, configuring different aspects (users/php-fpm pools, nginx hosts..) for each of sites. With more clients, I sat up ISPConfig on my second server, everything is easily handled by ISPConfig Web Interface. However, I am searching for a CLI based solution, i.e. a set of scripts to create and manage hosts. Basically, a method to control ISPConfig from the command line (so I can use it over SSH) would be a good start. Does anybody know of such effort? I searched but all I got was web based solutions. Thanks.
