• android game: how to approach mutliplayer

  - by willmer

  I'm making a single player game that is near completion, and I am already starting to think about giving the game multiplayer. The multiplayer would basically be finding someone to play against, likely in a waiting room or just have a match-making function, and then having a pokemon style battle between the people in real time. I think it would be relatively simple as I'm just sending information about each attack(move chosen and damage) and what it did back and forth, but I'm not sure what resources to consult for this. I am very new to Android/Java development and really just learning as I go. I have heard a bit about Skiller, but I'm still unfamiliar with using other SDK's and how easy it may be. Does anyone have any suggestions as to what SDK's or methods for accomplishing this. I currently have no money to spend on software development, but I'd like to get started on learning how to do this.

• Are there some types of software that cannot be developed by all major programming languages?

  - by mbillard

  I'd like to know if some of the major programming languages can absolutely not be used to create some very specific types of software. By major programming language I mean the likes of C++, C#, Java, Ruby, Python. By "cannot be developed" I mean cannot be developed or it is unrealistic to do it due to performance, difficulty of implementation, etc. I've always thought that any programming language could be used to solve any problem but lately I've been thinking that some languages are unsuitable for some projects. If you can provide examples of such applications, it would be appreciated. Thanks.

• UndoRedo on Nodes (Part 2)

  - by Geertjan

  After the recording of the latest API Design Tip for the upcoming NetBeans Podcast, Jaroslav Tulach helped me with the problem I blogged about yesterday. First he expressed surprise at seeing Undo/Redo work on Nodes, which was never the intention, i.e., that feature was always intended for documents, e.g., the Java editor. However, he then showed me where to find the Properties window in the NetBeans sources, where it is org.netbeans.core.windows.view.ui.NbSheet. It turns out that the Properties window does not have an activated node and hence the Node that implements UndoRedo.Manager is never put in the Lookup. Once we added, on line 303, "this.setActivatedNodes(nodes);", everything worked as expected, i.e., the Undo/Redo actions are now enabled, even when the Properties window is selected: Maybe it means I should file an issue to get that line added to NbSheet?

• JEditorPane Code Completion (Part 3)

  - by Geertjan

  The final step is to put an object into the Lookup on key listening in each of the JEditorPanes, e.g., a "City" object for the CityEditorPane and a "Country" object for the CountryEditorPane. Then, within the CompletionProviders, only add items to the CompletionResultSet if the object of interest is in the Lookup. The result is that you can then have different code completions in different JEditorPanes, as shown below: I've also included the Tools | Options | Editor | Code Completion tab, so that the code completion can be customized. The full source code for the example is here: java.net/projects/nb-api-samples/sources/api-samples/show/versions/7.2/misc/CustomerApp

• Has Dart something useful that javascript doesn't have?

  - by marko

  http://www.dartlang.org/ I've checked out the site very briefly, and got curious. Is there any advantages of using Dart? Is it just a replacement for javascript? It looks like simpler java. Writing quite a lot of C# at work, the language feels very much like what I'm used to, so learning the syntax looks like a breeze to learn. Has anybody any opinions or experiences with the language? (Compared to coffeescript (= I'm not doing ruby syntax) the syntax looks more familiar to me).

• Moving from an IT department to a proper technology company

  - by user2434

  I have been working with Java/web applications in an IT department of a retail company. As much as work goes, there is nothing much to say. Fixing couple of if/else loops, writing some simple business logic etc., is all what I have been doing. Having said that, I feel I have a good technical knowledge, and I am willing to move to companies like Microsoft/Google/Amazon etc., [I want to work in these places, because I feel I am a technical guy, and I am working in a place where most people freak out when the words like 'algorithm' are heard] I can of course prepare algorithms/computer science fundamentals etc.,(I hold a 4 year degree in computer science program) but beyond that, will my experience hold against me ? I doubt I'll even get a call from them seeing my work experience. What kind of questions(apart from the algorithm types) can I expect ?

• Overriding a function in an instance [on hold]

  - by MustSeeMelons

  Is it possible to override a function by instance? For example, A and B are both instances of MyClass. I have a function Action(), and I want to specify its implementation for each instance. To be more specific - the class is a Button, and the function is Clicked(). I don't want to derive a class 5 times to create 5 different button actions. Was thinking of something like it's handled in Java Swing: create a button, add code for the button press and use the button.

• How to make Classic ASP interesting if you are stuck with it?

  - by reno812

  I used to work on a really small outsourcing company (4 programmers and the boss), then when the stress and the frequent long shifts made the situation unbearable I made the switch to a better paid job with a more relaxed schedule that allows me some more free time. The problem, however, is that for the most part, everything is coded in Classic ASP that interfaces with a custom made C++ queueing system that stores everything in AS400 systems. My boss used to be one of the developers that made the initial efforts towards this, and naturally won't ever approve a switch to another languages / technologies despite the increasing difficulty that represents developing today business needs with yesterday tools. I'm pretty much stuck coding with Classic ASP in the foreseeable future, and I'm struggling to find ways to make it at least interesting, as I used to work with .NET and Java previously, and I feel like I'm going backwards... Any advice?

• Is there a language that allows this syntax: add(elements)at(index);

  - by c_maker

  Does a language exist with such a syntax? If not, what are some of the limitations/disadvantages to this syntax in case I want to write a language that supported it? Some examples: sort(array, fromIndex, toIndex); vs sort(array)from(index1)to(index2); Method signature would like this: sort(SomeType[] arr)from(int begin)to(int end){ ... } Update: Because there might be some confusion, I'd like to clarify... I meant this question as a general idea like this (not specific to sorting and possibly using keywords like from and to): In JAVA(like language): void myfancymethod(int arg1, String arg2){ ... } myfancymethod(1, "foo"); In imaginary language: void my(int arg1)fancy(String arg2)method{ ... } my(1)fancy("foo")method;

• Que pensez-vous du langage XML, faut-il passer à autre chose ?

  Bonjour, Ca y est. Au plaisir d'ouvrir un livre Java récent et de découvrir qu'un mot-clé supplémentaire (pour les pratiquants, une annotation) dans mon code source saura remplacer un fichier XML dont la présence était auparavant obligatoire, je me dis que nous sortons peut être d'une période où tout n'était qu'XML. Jusqu'à l'indigestion. Il y en eu partout et pour tout. Si pour l'échange de données entre systèmes il avait des atouts certains, je défends la thèse qu'il a été utilisé abusivement. Le paramétrage des composants, par exemple, est trop souvent passé par lui. Et cela a mené à des situations extrêmes. Il devenait parfois plus délicat de réussir son XML de paramétrage ou de compilation que le propre code source que l'on v...

• STL for games, yea or nay?

  - by munificent

  Every programming language has its standard library of containers, algorithms, and other helpful stuff. With languages like C#, Java, and Python, it's practically inconceivable to use the language without its standard lib. Yet, on many C++ games I've worked on, we either didn't use the STL at all, used a tiny fraction of it, or used our own implementation. It's hard to tell if that was a sound decision for our games, or one simply made out of ignorance of the STL. So... is the STL a good fit or not?

• Music Players in Ubuntu/Linux [closed]

  - by v2r

  Music Player, just like Web Browsers are an important part of today's application repertoire, and not only for entertainment reason. Having tried a few Linux Player over the past years i come to wonder, which Players you prefer and what kind of Players are out there, that you suggest are worth looking into and why!! I used Rhythmbox for a long time, but "Jamendo and Magnatune" plugin are both no longer available in 11.10 and also my covers are not shown, since i stream my music folder from a second partition. aTunes is another great Player, but there are also some flaws which i contacted the developers about. It would be nice if you post some alternatives! --Thank you. Example: Name of Player: aTunes | Homepage Additional Info : aTunes is a java-based Music-Player for Linux/Unix/Windows and ... Only one player-example per answer, please!!

• Where to upload my small apps or codes

  - by user108386

  My question is simple, but I couldn't found a good answer to it. Where to upload my code and my apps? I searching for a place where people find them. Homeworks, hobby projects, little helper scripts, and other open-source stuff. Does it depend on the used technology? I know, there are a lot of subversioning and project hosting systems. But where to start? I don't really know what I'd like. Maybe a wiki-post in the topic with paragraphs like: Upload you open source Winforms app to somesite or If you want to develop a Java library with your friends , use someothersite or Freeware stuff's best place is: ...

• C++ developer looks for book(s) about Android apps & widgets (& services etc.) [on hold]

  - by Valmond

  I'm senior C++ developer, I have also programmed professionally j2me some years. I'd like to make some apps and widgets for Android and I'd like to read up a bit on this new java stuff Android is using. I have (of course) checked out some tutorials and so but it seems I miss the basics, I can compile some stuff (read: examples) in eclipse but I just don't know how to, for example, add a service or what an 'intent' is, why my widget isn't called but successfully launches the main app when clicked and so on. So, what is a really good book for someone that is a developer but mostly need the hard facts about developing something specific like Android apps & widgets? Thanks a bunch!

• How can one combat boredom?

  - by sten29

  I'm not sure if it is a right place to ask about it but I think it is worth to try. I am PHP programer with near 5 years professional experience. I passed Zend certificates (PHP4, PHP5, ZF), I know almost everything what I should know. And the problem is, that I am bored. I think that I should change technology. It will give me a boost. It will give me satisfaction from work again. But I'm not sure what to choose. Java, .Net, C++ or maybe something other? I am really open to any technology. Have you ever had similar problem? What do you think about it? Maybe I should try few months holiday instead changing language?

  - by Ronney P

  I've been reading questions and discussions on this website but haven't made an account to start talking or asking anything I had doubts in so please bare with a newbie here. What are specific languages that have are able to make a program that will record, and organize things such as hours, salaries, payments? Also solve business problems, mostly with payments, how much money there will be after interest, taxes and such. Anyway, I've been looking into COBOL, C++, Java, HTML, JavaScript, VB.NET and a couple more. Which ones should I focus on and look into more? I very much appreciate any answers. Thank you.

• Using PDO for Data Management

  - by edorahg

  This question is more a design oriented question than a code specific question. I am new to PHP and I am planning to use PDO as a data access layer. Say for instance I have a class called CITY. Now if I need to create an instance of this class, what is the best technique. Should have a singleton DB access class which is used to write and read data from the db layer. OR should I delegate it to the individual class object. For example if I invoke city.save() (city is a class), then the city class will handle the saving of that city object's data into the database. Excuse my ignorance but i have a java background and therefore trying to understand what is the best design principle for data management when using php.

• What programming Langauge Would you learn to Reengineer USB Devices? [closed]

  - by user70113

  Currently Work in IT support and am retraining in electrical engineering / electronics, I am also interested in Reverse Engineering which language would be best for Hardware RE, I have seen a few sources say C, C++ and Python? I am not familiar with Linux, but installed ubuntu to learn with. I am not a programmer far from it, but I can understand enough basic VB,Java and PHP to edit it for simple things. One of my immediate projects would be to learn to reverse engineer USB devices and write my own low level drivers, I know there are porting kits, but I really want to know it from the ground up. Thanks for any advise folks Most Appreciated.

• Visual Studio 2012 and Game Development

  - by amongrain

  Alright, I think it's a simple question, but I got difficulties to find some answers around. I already read that XNA wouldn't be in Visual Studio 2012. I recently learned to use XNA, but since I would like to work on games, I'd like to know if there's a way to develop games using C# on Visual Studio 2012, or if I should learn everything again using C++ and Direct3D? C# is a language I like a lot, so if there's no way to do it in C# but something quite easy to use Java for game development, I'd also be interested. Thanks a lot!

• How to gain understanding of large systems? [closed]

  - by vonolsson

  Possible Duplicate: How do you dive into large code bases? I have worked as a developer developing C/C++ applications for mobile platforms (Windows Mobile and Symbian) for about six years. About a year ago, however, I changed job and currently work with large(!) enterprise systems with high security and availability requirements, all developed in Java. My problem is that I am having a hard time getting a grip on the architecture of the systems, even after a year working with them, and understanding systems other people have built has never been my strong side. The fact that I haven't worked with enterprise systems before doesn't exactly help. Does anyone have a good approach on how to learn and understand large systems? Are there any particular techniques and/or patterns I should read up on?
