• Why Adobe Air is so underrated for building mobile apps?

  - by Marcelo de Assis

  I worked with Adobe Flash related technologies for the last 5 years, although not being a big fan of Adobe. I see some little bugs happening in some apps, but I cannot imagine why a lot of big companies do not even think to use use Adobe Air as a good technology for their mobile apps. I see a lot of mobile developer positions asking for experts in Android or iOS , but very much less positions asking for Adobe Air, even when Adobe Air apps have the advantage of being multi-plataform, with the same app working in Blackberry, iOS and Android. Is so much easier to develop a game using Flash, than using Android SDK, for example. It really have flaws (that I never saw) or it is just some kind of mass prejudgement? I also would like to hear what a project manager or a indie developer takes when choosing a plataform for building apps.

• Looking for a good actionscript 3 book

  - by Jari Komppa

  I've been looking for a book on actionscript3 development, but while there's tons of books out there, nobody seems to want to recommend any specific one. One book I've been pointed towards is the cookbook by o'reilly, but it, like most books out there, seems to be based on the assumption that I'm using flexbuilder or flash. Instead, I'm "just" using flashdevelop, or the free SDK directly. I've also been told to just go with the api reference and live with it. I could do that, I suppose, but I'd rather have a book that gives me the big picture. Kind of like with cocoa, there's the hillegrass' book, or the red book of OpenGL. So, what would be the actionscript3 book out there?

• Exporting XNA class library as a DLL file

  - by Will Bagley

  I have downloaded an open source project that I intend to use with my current game. The download came with all the class files from the original project as well as a pre-compiled DLL file representing the project. I was able to easily link this DLL with my current project and get it working just fine, no problems there. The problem I now have is that I want to make a couple of changes to the original libraries (extend its functionality a bit to better suit my needs) and re-export the class library as a DLL again, but I have no clue how to do this. Is there some simple way in VS where I can just take the class library and export/compile it as a DLL file again or is there more to it than that? This seems like something that should be pretty simple but my efforts to find an answer have so far come up with nothing. Thanks in advance.

• XNA: Auto-populate content within the content project based on current folder/file structure and content management for large games

  - by Joe

  1) Is it possible to implement a system where I can simply drop a new image into my content project's folder and VS will automatically see that and bring it into the project for compiling? 2) Similarly, if I wanted a specific texture I could state something like var texture = Game.Assets.Image["backgrounds/sky_02"]; (where Game is the standard XNA Game class and Assets is some kind of content manager statically defined within Game). I know this is fairly simple to implement manually and have done such things in the past (static Dictionary defined within Game) except this only works for relatively small games where you can have all assets loaded at the start without much issue. How would you go about making this work for games where content is loaded and unloaded based on level / area? I'm not asking for the solution, just how you would go about this and what things you would have to be aware of. Thanks.

• IIS Not Accepting Login Credentials

  - by Dale Jay

  I have an ASP.NET web form using Microsoft's boilerplate Active Directory login page, set up exactly as suggested. (See http://msdn.microsoft.com/en-us/library/ms180890%28v=vs.80%29.aspx) Windows Authentication is activated on the "Default Website" and "MyWebsite" levels, and Domain\This.User is given "Allow" access to the site. After entering the valid credentials for This.User on the web form, a popup window appears asking me to enter my credentials yet again. Despite entering valid credentials for This.User (after attempting Domain\This.User and This.User formats), it rejects the credentials and returns an unauthorized user page. Active Directory user This.User is valid, the IP address of the AD server has been verified and SPN's have been set up for the server. Any thoughts as to what may be causing this? I can post code if needed.

• When to do Code Review

  - by mcass20

  We have recently moved to a scrum process and are working on tasks and user stories inside of sprints. We would like to do code reviews frequently to make them less daunting. We are thinking that doing them on a user story level but are unsure how to branch our code to account for this. We are using VS and TFS 2010 and we are a team of 6. We currently branch for features but are working on changing to branching for scrum. We do not currently use shelvesets and don't really want to implement if there are other techniques available. How do you recommend we implement code review per user story?

• Is extensive documentation a code smell?

  - by Griffin

  Every library, open-source project, and SDK/API I've ever come across has come packaged with a (usually large) documentation file, and this seems contradictory to the wide-spread belief that good code needs little to no comments. What separates documentation from this programming methodology? a one to two page overview of a package seems reasonable, but elegant code combined with standard intelisense should have theoretically deprecated the practice of documentation by now IMO. I feel like companies only create detailed documentation and tutorials because its what they've always done. Why should developers have to constantly be searching through online documentation in order to learn how to do things when such information should be intrinsic to the classes, methods and namespaces?

• Translating an Object to a certain Vector 3 in OpenGL and Java LWJGL

  - by aliasmk

  So after almost two hours, I got the hang of using glTranslated() (with Java and LWJGL). If I am correct, applying glTranslated on an object moves that object with the x,y,z relative to the previously moved object. I believe the correct term for this is local vs global, global being the one I want. I was wondering if there was a way to translate an object to a specific XYZ position, or relative to the origin. Thanks! (Code or other details can be supplied if it helps, just let me know. Also sorry if this is a noob comment, Im very new to OpenGL.)

• Would a multitouch capable PC allow me to do Android development simulating the touch UI without an Android device ?

  - by Scott Davies

  Hi, I recently purchased a Samsung Galaxy Tab as a reference implementation (phone and first gen Android tablet), of Android 2.x for app development. I have noticed a slew of Android 3.0 slates being talked about at CES 2011 (Motorola XOOM, etc.). If I had a multitouch PC with the Android SDK/Emulator on it, would this allow me to more closely approximate device simulation by allowing user input via the multitouch screen ? Would it work via touch just like Windows 7 recognizes touch as mouse style input ? Has anyone done this ? Thanks, Scott

• Not getting paid for hours you've worked?

  - by Mercfh

  So I was reading from a previous thread about App vs Game Development Here Which brought me to this site: Clicky Alot of it talked about devs working something like 85 hours a week.....and not getting paid overtime, or anything. Just getting paid for the 40 hours.....Is this normal for most software companies? I mean where I work im only an entry level guy....but I get overtime, and Anything over 40 hours is considered this. But it got me thinking "Holy crap" I could never do that. My FREE time is important to me. But is this commonplace in most software companies? or...more a rarity to certain types (game development, etc) Cause it got me scared! Like I understand having to put some extra hours in for a project......but like 80! thats ridiculous.

• Should programming languages be strict or loose?

  - by Ralph

  In Python and JavaScript, semi-colons are optional. In PHP, quotes around array-keys are optional ($_GET[key] vs $_GET['key']), although if you omit them it will first look for a constant by that name. It also allows 2 different styles for blocks (colon, or brace delimited). I'm creating a programming language now, and I'm trying to decide how strict I should make it. There are a lot of cases where extra characters aren't really necessary and can be unambiguously interpreted due to priorities, but I'm wondering if I should still enforce them or not to encourage good programming habits. What do you think?

• Development on Terminal or IDE [on hold]

  - by Taylor Flores

  I've been using nano, make, gcc, and gdb for 6 months now and I've found it much easier than using VS or Codeblocks. But I'm wondering now: Is development on a terminal more/less efficient that using an IDE? In what situations is one preferred more sensible than the other? I'm not asking about opinions, I want to know if there's specific reasons to use one over the other. From what I can gather: terminals can be used on environments where a GUI is not available terminal projects can be created and configured more quickly IDEs contain better syntax highlighters (ie identity highlighters) This question is C biased, but I think it's relevant to other languages as well.

• How to fo fluid dynamics like Where's My Water?

  - by Edgar Miranda

  There is a game on the app store called "Where's My Water" that is really fun and uses fluid dynamics in it's gameplay. You can check out a video of the game play here... http://www.youtube.com/watch?v=UnFFWnwOohk. You use your finger to remove dirt from the screen, and then the water just flows to the new area. Anyone know what engine this was made in and how they where able to get the fluid dynamics in there? I'm using the Corona SDK for mobile development and want to do something similar like this (a game with fluid dynamics).

• Automated architecture validation

  - by P.Brian.Mackey

  I am aware of the fact that TFS 2010 ultimate edition can create and validate architecture diagrams. For example, I can create a new modeling project add Layer Diagram Add Layer called View Add BL Layer Add DL layer. Then I can validate this architecture as part of the build process when someone tries to check code into TFS. In other words, if the View references the DL then the compilation process will fail and the checkin will not be allowed. For those without an MSDN ultimate license, can FxCop or some 3rd party utility be used to validate architecture in an automated fashion? I prefer a TFS install-able plugin, but a local VS plugin will do.

• DAC pack up all your troubles

  Visual Studio 2010 is being geared up to become the natural way for developers to create databases. Central to this drive is the introduction of 'data-tier application components', or DACs. Something had to be in place for VS2010, but right now DAC packs only make sense for Azure. For this, they're cute, but hardly compelling. Nevertheless, DBAs would do well to get familiar with VS 2010 and DAC packs. Like it or not, they're both coming....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• FlasCC requirements and limitations?

  - by Arthur Wulf White

  It is now available for download. It says you need twice* as many bits as I have. Why would you need more bits to compile code? Does that mean you need more bits to run flash games writtes with flasCC Did anyone try it out and happens to know the answers? http://gaming.adobe.com/technologies/flascc/ Minimum system requirements Flash Player 11 or higher Flex SDK 4.6 or higher Java Virtual Machine (64-bit) Windows Microsoft® Windows® 7 (64-bit edition) Cygwin (included) *This is meant as a joke. however I do own a 32-bit laptop and I am wondering why you need 64-bit. Afaik - You only need 64-bit if you want to run a system that has more than 4gigs of memory. Why would any flash game require more than 4 gigs of memory. The only system that is 64-bits and does not have 4gigs of memory that I can quickly recall is that hilarious Nintendo that came ages ago with a Motorola CPU.

• Why should I use List<T> over IEnumerable<T>?

  - by Rowan Freeman

  In my ASP.net MVC4 web application I use IEnumerables, trying to follow the mantra to program to the interface, not the implementation. Return IEnumerable(Of Student) vs Return New List(Of Student) People are telling me to use List and not IEnumerable, because lists force the query to be executed and IEumerable does not. Is this really best practice? Is there any alternative? I feel strange using concrete objects where an interface could be used. Is my strange feeling justified?

• Attached Property port of my Window Close Behavior

  - by Reed

  Nishant Sivakumar just posted a nice article on The Code Project.  It is a port of the MVVM-friendly Blend Behavior I wrote about in a previous article to WPF using Attached Properties. While similar to the WindowCloseBehavior code I posted on the Expression Code Gallery, Nishant Sivakumar’s version works in WPF without taking a dependency on the Expression Blend SDK. I highly recommend reading this article: Handling a Window’s Closed and Closing Events in the View-Model.  It is a very nice alternative approach to this common problem in MVVM.

• Android: debug certificate expired error

  - by Bill Osuch

  I started up Eclipse today, created a new project, and immediately had an error before I had changed a single line: Error generating final archive: Debug Certificate expired on 11/12/11 When installed, the Android SDK generates a "debug" signing certificate for you in a file called "debug.keystore". Eclipse uses this certificate rather than forcing you to create a new one for every project. In older versions of Eclipse, the certificate was only valid for 365 days, but as I understand it the default has been changed to 30 years in newer versions. If for whatever reason you don't want to upgrade Eclipse, you can manually delete the certificate to for Eclipse to generate a new one. You can find the location in Preferences -> Android -> Build -> Default debug keystore (mine was in C:\Users\myUserName\.android\); just delete the "debug.keystore" file, then go back into Eclipse and Clean the project to generate a new file.

• How to explain OOP to a matlab programmer?

  - by Oak

  I have a lot of friends who come from electrical / physical / mechanical engineering background, and are curious about what is "OOP" all about. They all know Matlab quite well, so they do have basic programming background; but they have a very hard time grasping a complex type system which can benefit from the concepts OOP introduces. Can anyone propose a way I can try to explain it to them? I'm just not familiar with Matlab myself, so I'm having troubles finding parallels. I think using simple examples like shapes or animals is a bit too abstract for those engineers. So far I've tried using a Matrix interface vs array-based / sparse / whatever implementations, but that didn't work so well, probably because different matrix types are already well-supported in Matlab.

• ADF Mobile Application in the Apple AppStore

  - by Joe Huang

  Hi, everyone: I would like to announce that there is now an iPhone App in the Apple AppStore that's built using Oracle ADF Mobile.  This app is the Hudson Mobile Monitor application for the iPhone, which allows you to monitor build status for the Hudson Continuous Integration server.  By default it points to the production instance of the Hudson CI server hosted at Oracle.  One of the key goals for ADF Mobile in general is to ensure an application built using ADF Mobile is compliant with Apple iOS SDK terms.  We designed the framework to ensure applications can go through the approval process - of course there are still things that can be done which would cause issues during the approval process, and we will be publishing more best practices in the coming articles. Thanks, ADF Mobile Product Management Team.

• Version Changes: How considerable are the compatibility issues in project?

  - by Aditya P

  For example if we consider ActionScript2.0(based on Objects but programming does not implement much OOP ) vs 3.0(highly OOP) its like a whole new scripting language in the sense of approach, programming style,features you get the idea. In PHP we can see current versions going from 3-5. brief version changes Question :Developers who work on PHP is it easy to migrate from version to version? Question :Are there any extensive compatibility issues, forward or backward? Question :Does your project stick to a particular version till the end ? Question :Does the programming style ,approach change from version to version? Question :If you had to get started on PHP to contribute to a project built earlier versions, would learning the latest version be counterproductive towards this aim? Some related topics i had come across on SE How should I be keeping track of php script version/changes? What is happening to PHP 6? It would be Really helpful in understanding if you could answer this topic directly to the questions put forth.
