• Too much to learn, so little time

  - by Phobia

  Okay, so I'm a java developer (or at least I think I am),and also a student at the same time I want to get a job when I graduate,I'll be graduating in a year or so (hopefully) (Note: my major has nothing to do with programming) Now, I'm between a rock and a hard place I also want to nail the foundations to become a good software developer. I want to be able to write programs that solve problems,not just glue code The software market in my country for java developers is just a few developers working with Java EE (struts,spring,hibernate....etc) I'm currently learning C++ with this book. I've also watched most of the 1st lecture of this course and I understood pretty much everything I watched To sum it up, I have three options Learn Java EE Learn C++ Learn Scheme Which is better for me at this point?

• Shader inputs in a general purpouse engine

  - by dreta

  I'm not familiar with SDKs like Unity or UDK that much, so i can't check this off hand. Do general purpouse engines allow users to create custom uniform variables? The way i see it, and the way i have implemented it in an engine i'm writing to learn 3D, is that there is a "set" of uniforms provided by the engine and if you want to write a custom shader then you utilize uniforms you need to create a wanted effect. Now, the thing is, first of all i'm not an artist, second of all, i didn't have a chance to create complex scenes yet. So my question is, is it common practice to define variables that the engine provides and only allow the user to work with what they're given? Allowing users to add custom programs and use them where they want is not hard, but i have issues imagining how you'd go about doing the same for uniforms.

• How should I organize my matrices in a 3D game engine?

  - by Need4Sleep

  I'm working with a group of people from around the world to create a game engine (and hopefully a game with it) within the next upcoming years. My first task is to write a camera class for the engine to use in order to add cameras to the scene, with position and follow points. The problem I have is with using matrices for transformations in the class, should I keep matrices separate to each class? Such as have the model matrix in the model class, camera matrix in the camera class, or have all matrices placed in one class/chuck? I could see pros and cons for each method, but I wanted to hear some input form a more professional standpoint.

• Balancing full time work and personal coding projects.

  - by pllee

  I am nearing the end of developing the major pieces of my website that I have been working on in my spare time for the last 3 months. My goal is to get it released by the end of next month and hopefully start making some money on it. Unfortunately the next step will be to write a lot of specific data handling and ui code that I can see becoming very tedious and boring. When I was first started the project I was able to find time for working on it easily, it was interesting and writing the back-end was new. Once I got to the start of writing stuff that I know and do at work (ui), it seemed harder and harder to make myself work on the project, sometimes the last thing I want to do when I get home from work is code again. Anyone in the same situation? Any tips on how to find time and effort for side projects without burning out? Any tips on staying on the right track?

• Online architecture guide

  - by hunterman

  I am a newbie in gamedev, and I don't know about programmer's problems that can appear during development. So can you advice me some best practice for starting build new online multi-player game backend? I just saw reddraft server, and I think Spring library can also do some of its features. What is big difference? Do I need learn more spring or I have to use servers like reddraft or write these tools myself? I know that I need to learn hard and many - and the question is - what I should to learn now at the beginning? Thanks.

• 2D management game [on hold]

  - by Simon Bull

  Very newbie question but I have a game idea in mind. It will be 2d and data centric, like football manager. However I am struggling to find a platform that would suit. I am an experienced line of business developer so am happy to write code, but I would like a platform that does some of the leg work for me so was avoiding OpenGL. I would also like to be able deploy to iOS, android, windows and OS X. What are the options? To be more clear, the game is not a normal platform or shooter type game, so game maker is likely to be way too basic and unity seems a little over the top (though I am not sure if the GUI options would fit?). The majority of the game is more like business screens just displaying data and having buttons to click. Are there options for this type of game (May help to look at football manager)?

• Writing jenkins plugin: where is the documentation?

  - by user22070

  On my current project we're using Jenkins to monitor our builds. Now they want me to write a Jenkins plugin to add some more monitoring parameters. I've taken a look at how the status monitor plugin works, and I can't figure some things out. I've tried to look for documentation for writing a plugin, but that seems to be sorely lacking. (the site only mentions how to generate the base project, and refers to a tutorial that's not that informative) What I'm trying to do is just add some options to each build, add a link, and a monitoring page. Adding to the main page is apparently done by adding the action, but I'm still trying to figure out the rest. And how it all ties in. Does anyone have any pointers, or a place where I can find some decent documentation?

• Getting graduates up to speed?

  - by Simon

  This question got me thinking about how comapnies deal with newly-hired graduated. Do experienced programmers expect CS graduates to write clean code (by clean I mean code easily understandable by others — maybe that is too much to expect?) Or do significant portion of graduates at your place (if any) just end up testing and fixing small bugs on existing applications? And, even if they do bug fixes, do you end up spending double the amount of time just checking they did not end up breaking anything and creating new bugs? How do you deal with such scenarios when pair programming and code reviews are not available options (for reasons such as personal deadlines), and also what techniques did you find to get fresh graduate up to speed? Some suggestions would be great.

• Plan variable and call dependencies

  - by Gerenuk

  I'd like to write down the design of my program to understand the dependencies and calls better. I know there are class diagrams which show inheritance and attribute variables. However I'd also like to document the input parameters to method functions and in particular which calls the methods function executes inside (e.g. on the input parameters). Also sometimes it might be useful to show how actual objects are connected (if there is a standard structure). This way I can have a better understanding of the modules and design before starting to program. Can you suggest a method to do this software design? It should be one-to-one to programming code structure so that I really notice all quirks beforehand (instead of high-level design where thing are hard to implement without further work). Maybe some special diagram or tool or a combination? It is static dependency and call design rather than time dependent execution monitoring. (I use Python if you have any specialized recommendations).

• .NET Reflector Open Source Alternative

  - by bconlon

  When I found out yesterday that one of my top 5 development tools .NET Reflector will no longer be free at the end of February, I thought I'd see if work had started on a good open source alternative...and guess what...work on ILSpy is already well underway!! There seems to be a difference of opinion on what Red Gate said when they purchased .NET Reflector from Lutz Roeder in 2008. They say that they would try to keep it free, where as others think they promised to keep it free. Either way at the time I thought it was a smart purchase by Red Gate as it would raise their profile overnight within the .Net community. But not only are they going to charge $35 for v7 (which is up to them), they have also time-bombed v6 to force users to pay. This I think will lower their profile overnight within the .Net community!! Maybe they are been slightly naive in thinking the community wouldn't just write an alternative?  #

• Should actors in a game be responsible for drawing themselves?

  - by alex

  I am very new to game development, but not to programming. I am (again) playing around with a Pong type game using JavaScript's canvas element. I have created a Paddle object which has the following properties... width height x y colour I also have a Pong object which has properties such as... width height backgroundColour draw(). The draw() method currently is resetting the canvas and that is where a question came up. Should the Paddle object have a draw() method responsible for its drawing, or should the draw() of the Pong object be responsible for drawing its actors (I assume that is the correct term, please correct me if I'm incorrect). I figured that it would be advantagous for the Paddle to draw itself, as I instantiate two objects, Player and Enemy. If it were not in the Pong's draw(), I'd need to write similar code twice. What is the best practice here? Thanks.

• s expression representation for c

  - by wirrbel

  Experimenting with various lisps lately (clojure especially) i have wondered if there are any s expression based representations of (subsets) of c, so you could use lisp/closure to write macros and then convert the s-expression c tree to pure c. I am not asking for a to-c-compilers of lisp/scheme/clojure but more of using lisps to transform a c syntax tree. Little background to why i am asking this question: i find myself to really enjoy certain clojure macros like the threading macros -> doto etc. And i feel that they would be great in a non FP environment as well.

• Openx api Advertiser statistics call [migrated]

  - by Sameer

  I am trying to write a jsp application which will establish the xmlrpc connection with openxapi and return the values. I am using openxapi v1 Here I get the dates through a datepicker and then convert to date format: `String dateStr = request.getParameter("datum1"); SimpleDateFormat formater = new SimpleDateFormat("dd-MM-yyyy"); Date result1 = formater.parse(dateStr); String dateStr2 = request.getParameter("datum2"); SimpleDateFormat formater2 = new SimpleDateFormat("dd-MM-yyyy"); Date result2 = formater2.parse(dateStr2);` Then I call the service provided by openxapi (Advertiser Daily Statistics) (sessionID, advertiserID, from date, to date) Object[] objects1=(Object[])client.execute("advertiserDailyStatistics", new Object[]{sessionId,3,result1,result2});

• Questions Anyone?

  - by Kevin Smith

  I've been working with WebCenter Content for almost 9 years now and have a ton of topics rolling around my head that I'm sure would make excellent blog post once I find the time to write them up. Does anyone have any questions they would like answered? Like why does WCC do ...? How does this feature work? I can't seem to get this working? Post your question to the comments and if it is something on my list of topics I had planned on creating a blog post about I will move it to the top of the list.

• User prompts (MessageBox) with MVVM

  - by mukapu

  The problem statement: I am tired of thinking how to show a simple message box or user prompt and act based on the response in Model-View-View-Model (MVVM). Common approaches: - It's ok, let's just do this one thing from ViewModel and mock this out for unit testing - Design my own dialog, then what to do from there - Can I write something in view code behind, ah yes, that seems to be the only way out, as anyway MVVM is still not matured...  - and what not?   I am pretty much one among the few frustrated out in this world looking for some convincing answers. I think we can do it a little neater without having the feeling of violating any of our self defined rules! Solution: The Control - Implement a simple control with no designer visibility. - Allow a property to be bound to tell when to show the MessageBox - Provide command binding for possible user actions, Yes, No, Cancel... How do I Use? - Just place the necessary XAML tags in the view - Implement the command for all user actions in the View Model - Run unit tests on the commands

• Missing return statement when using .charAt [migrated]

  I need to write a code that returns the number of vowels in a word, I keep getting an error in my code asking for a missing return statement. Any solutions please? :3 import java.util.*; public class vowels { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Please type your name."); String name = input.nextLine(); System.out.println("Congratulations, your name has "+ countVowels(name) +" vowels."); } public static int countVowels(String str) { int count = 0; for (int i=0; i < str.length(); i++) { // char c = str.charAt(i); if (str.charAt(i) == 'a' || str.charAt(i) == 'e' || str.charAt(i) == 'o' || str.charAt(i) == 'i' || str.charAt(i) == 'u') count = count + 1; } } }

• Vala: How to use Glades ActionGroup correctly

  - by Tom

  Could someone give me an example how to use Glade's ActionGroup with a Gtk.Builder in a Vala-Application? If I have an ActionGroup with an Action save, and on this action I've set the activate Signal to "on_save_clicked", should it be fine to write: [CCode (instance_pos = -1)] public void on_save_clicked(){ print("I would like to save, please\n"); } in global scope and then use builder.connect_signals(null)? When i do this, i just get "Could not find signal handler 'on_save_clicked'" when executing the program. No compile errors. I'm using valac --pkg gtk+-3.0 test.vala for compiling and glade-3.10.0

• Terms and conditions for a simple website

  - by lonekingc4

  I finished building a website for an online chess club which I am a member of. This is my first website. The site has blogging feature so the members can log in and write blog posts and comment on other posts. The membership is limited to users of an online chess site (freechess.org) and any member of that site can join this site as well. I was wondering, is it needed to put up a terms and conditions for my new website? If so, can I have a model of that? I searched and found some models but they are all for big sites that have e-commerce etc.

• JSIL - a Dot Net to JavaScript translator

  - by TATWORTH

  JSI is described at http://jsil.org/ as:"JSIL is a compiler that transforms .NET applications and libraries from their native executable format - CIL bytecode - into standards-compliant, cross-browser JavaScript. You can take this JavaScript and run it in a web browser or any other modern JavaScript runtime. Unlike other cross-compiler tools targeting JavaScript, JSIL produces readable, easy-to-debug JavaScript that resembles the code a developer might write by hand, while still maintaining the behavior and structure of the original .NET code. Because JSIL transforms bytecode, it can support most .NET-based languages - C# to JavaScript and VB.NET to JavaScript work right out of the box."

• Should a web designer know server-side coding?

  - by Rasoul Zabihi

  We're implementing an CMS based on ASP.NET MVC. Now, any designer should be able to provide themes for this CMS. But to write a theme, they need to be able to modify the generated HTML, thus the concept of View. In other words, they should be capable to either modify current views, or create new views from scratch, to fit their requirements. However, now we're not sure that we're taking the right path. Should a web designer (HTML, CSS, JavaScript + Photoshop) really know about server-side platforms like Razor or PHP, or classic ASP, or anything else?

• Simplicity-efficiency tradeoff

  - by sarepta

  The CTO called to inform me of a new project and in the process told me that my code is weird. He explained that my colleagues find it difficult to understand due to the overly complex, often new concepts and technologies used, which they are not familiar with. He asked me to maintain a simple code base and to think of the others that will inherit my changes. I've put considerable time into mastering LINQ and thread-safe coding. However, others don't seem to care nor are impressed by anything other than their paycheck. Do I have to keep it simple (stupid), just because others are not familiar with best practices and efficient coding? Or should I continue to do what I find best and write code my way?

• Sprite/Tile Sheets Vs Single Textures

  - by Reanimation

  I'm making a race circuit which is constructed using various textures. To provide some background, I'm writing it in C++ and creating quads with OpenGL to which I assign a loaded .raw texture too. Currently I use 23 500px x 500px textures of which are all loaded and freed individually. I have now combined them all into a single sprite/tile sheet making it 3000 x 2000 pixels seems the number of textures/tiles I'm using is increasing. Now I'm wondering if it's more efficient to load them individually or write extra code to extract a certain tile from the sheet? Is it better to load the sheet, then extract 23 tiles and store them from one sheet, or load the sheet each time and crop it to the correct tile? There seems to be a number of way to implement it... Thanks in advance.

• How to design console application with good seperation of UI from Logic

  - by JavaSa

  Is it considered an overkill for console application to be design like MVC , MVP or N tier architecture? If not which is more common and if you can link me to simple example of it. I want to implement a tic tac toe game in console application. I have a solution which hold two projects: TicTacToeBusinessLogic (Class library project) and TicTacToeConsoleApplication (Console application project) to represent the view logic. In the TicTacToeConsoleApplication I've Program.cs class which holds the main entry point (public static void Main). Now I face a problem. I want the game to handle its own game flow so I can: Create new GameManager class (from BL) but this causing the view to directly know the BL part. So I'm a little confused how to write it in an acceptable way. Should I use delegates? Please show me a simple example.

• Working with vectors and transformations

  - by user29163

  I am going to write an graphical 2D application that allows user to create polygons and transform them through transformation such as rotation an so on. I was hoping someone can give pro and cons arguments for the different choices I got in my mind. (Its all in Java btw!) a). Represent vectors by filling matrices with 'real' numbers. This means making a matrix datas tructure that supports multiplication, transposing etc b). Make a own vector class, such that I can make a matrix class that support those vectors.

• iPhone 3d Model format: .h file, .obj, or some other?

  - by T Reddy

  I'm beginning to write an iPhone game using OpenGL-ES and I've come across a problem with deciding what format my 3D models should be in. I've read (link escapes me at the moment) that some developers prefer the models compiled in Objective-C .h files. Still, others prefer having .obj as these are more portable (i.e., for deployment on non-iPhone platforms). Various 3D game engines seem to support many(?) formats, but I'm not going to use any of these engines as I would like to actually learn OpenGL-ES. Am I putting myself at a disadvantage here by not using a packaged engine? Thanks!
