• Numerical stability in continuous physics simulation

  - by Panda Pajama

  Pretty much all of the game development I have been involved with runs afoul of simulating a physical world in discrete time steps. This is of course very simple, but hardly elegant (not to mention mathematically inaccurate). It also has severe disadvantages when large values are involved (either very large speeds, or very large time intervals). I'm trying to make a continuous physics simulation, just for learning, which goes like this: time = get_time() while true do new_time = get_time() update_world(new_time - time) render() time = new_time end And update_world() is a continuous physical simulation. Meaning that for example, for an accelerated object, instead of doing object.x = object.x + object.vx * timestep object.vx = object.vx + object.ax * timestep -- timestep is fixed I'm doing something like object.x = object.x + object.vx * deltatime + object.ax * ((deltatime ^ 2) / 2) object.vx = object.vx + object.ax * deltatime However, I'm having a hard time with the numerical stability of my solutions, especially for very large time intervals (think of simulating a physical world for hundreds of thousands of virtual years). Depending on the framerate, I get wildly different solutions. How can I improve the numerical stability of my continuous physical simulations?

• Should I concentrate on writing code for money or my studies while in college?

  - by A-Cube

  I am college student of Software Engineering. My worries are that while I am concentrating on my studies, my peers are getting down with the code (e.g. HTML, ASP, PHP, etc) to earn money. Should I be worried that I am not doing coding like them? I was asked to be Microsoft Student Partner but I refused because the person what was doing before me told it was just arranging events. Nothing as such like getting with Microsoft and coding. Should I be writing code and earning money as I still am in 4th semester? I only have C++ as learning language in college. Will my job count on these projects that I do, or should I concentrate on studies for now to get maximum benefit?

• Podcast with AJI about iOS development coming from a .NET background

  - by Tim Hibbard

  I talked with Jeff and John from AJI Software the other day about developing for the iOS platform. We chatted about learning Xcode and Objective-C, provisioning devices and the app publishing process. We all have a .NET background and made lots of comparisons between the two platforms/ecosystems/fanbois. They even let me throw in a plug for Christian Radio Locator. Jeff was my first contact with the Kansas City .NET community. It was probably about 10 years ago. He pushed me to talk more (and rescued me from my first talk that bombed) and blog more. One time a group of us took a 16 hour car trip to South Carolina for a code camp and live podcasted the whole thing. Good times.Listen to the show Click here to subscribe to more AJI Reports in the future.

• Just being hired as a senior developer, never even been a junior developer, what should I expect?

  - by Mark James

  I've been a freelancer and a coder by night for a while, and recently, I've been hired after several levels of interviews in a nice NY company, even though I've some lacks in specific fields. Is this common for companies to hire seniors with less experience? Will they wait some weeks to respect a certain learning curve? I don't know anything about working in a company, so that's why I worry. After one week, I'm still checking and exploring sources, but after one week of work, it seems that some coworkers are considering that I'm slow. I'm good in maths, physics, algorithms, but still I need to learn about all the templates used in this company. Anyone here already received a less-experienced senior member in his team? Is this acceptable? I'm planing on having a meeting with my boss to stop worrying about that. Sounds like a good idea?

• Why is web app development path in Java this much confusing? [closed]

  - by Farshid

  I'm currently a .net web developer and I really like to switch to Java. I've used JSP about 7 years ago to develop and deploy a small web application on a JRUN app server. But after 7 years that I like to return back to Java, I can't find the clue. There are many web development frameworks that exist in Java world and each of them has fans that recommand it. There are extensions that sit above jvm for web development (like jRuby i think). I am confused and I do not know where to start the path of learning java web development. I do not want to focus on custom tailor-made approaches and want to remain on the basic path of developing with standard tools and methods and deploy them into standard app servers. (For example some says do not use EJBs, some says focus on MVC facilities like JSF. I'm confused and I do not know the path that i should go on)

• Jump into Android or learn Java basics first?

  - by daniels

  I am quite proficient in C and know some C++, but never touched Java. Recently I got an idea for an app which I think has potential, and I want to develop it. I am planning to go Android first, cause it doesn't require a mac/iPhone. So my question is: can I go straight to learning Android development, picking up the Java syntax as I go along and need it (after all I don't think it's much different from C/C++), or should I take a couple of weeks to learn the basics of Java first and then start with Android development?

• How to modify VBO data

  - by Romeo

  I am learning LWJGL so i can start working on my game. In order to learn LWJGL I got the idea to implement the map builder so I can get comfortable with graphics programming. Now, for the map creation tool I need to draw new elements or draw the old one's with different coordinates. Let me explain this: My game will be a 2D scroller. The map will be consisting of multiple rectangles ( 2 strip triangles). When I click my left-mouse button i want to start the rectangle and when I release it I want to stop the rectangle bottom-right at that position. As I want to use VBOs I want to know how to modify data inside the VBO based on user input. Should i have a copy of a vertex array and then add the whole array to the VBO at each user input? How is usually implemented the VBO update?

• Making an efficient collision detection system

  - by Sri Harsha Chilakapati

  I'm very new to game development (just started 3 months ago) and I'm learning through creating a game engine. It's located here. In terms of collision, I know only brute-force detection, in which case, the game slows down if there are a number of objects. So my question is How should I program the collisions? I want them to happen automatically for every object and call the object's collision(GObject other) method on each collision. Are there any new algorithms which can make this fast? If so, can anybody shed some light on this topic?

• Where to start? (3D Modeling)

  - by herfus

  I'm looking for a good resource to start learning 3d modeling. I'm looking for something that starts with the basics (e.g. terminology; what are quads, triangles etc.) before/while going into the actual modeling. Book, website, video, anything will do. I'm only concerned with the quality of the tutorials, how thorough they are. I have experience with texturing, level design and so on - but I've never created anything more than simple shapes/editing existing assets.

• Outline Shader Effect for Orthogonal Geometry in XNA

  - by Griffin

  I just recently started learning the art of shading, but I can't give an outline width to 2D, concave geometry when restrained to a single vertex/pixel shader technique (thanks to XNA). the shape I need to give an outline to has smooth, per-vertex coloring, as well as opacity. The outline, which has smooth, per-vertex coloring, variable width, and opacity cannot interfere with the original shape's colors. A pixel depth border detection algorithm won't work because pixel depth isn't a 3.0 semantic. expanding geometry / redrawing won't work because it interferes with the original shape's colors. I'm wondering if I can do something with the stencil/depth buffer outside of the shader functions since I have access to that through the graphics device. But I don't believe I'm able to manipulate actual values. How might I do this?

• What the best way to wire up Entity Framework database context (model) to ViewModel in MVVM WPF?

  - by hal9k2

  As in the question above: What the best way to wire up Entity Framework database model (context) to viewModel in MVVM (WPF)? I am learning MVVM pattern in WPF, alot of examples shows how to implement model to viewModel, but models in that examples are just simple classes, I want to use MVVM together with entity framework model (base first approach). Whats the best way to wire model to viewModel. Thanks for answers. //ctor of ViewModel public ViewModel() { db = new PackageShipmentDBEntities(); // Entity Framework generated class ListaZBazy = new ObservableCollection<Pack>(db.Packs.Where(w => w.IsSent == false)); } This is my usual ctor of ViewModel, think there is a better way, I was reading about repository pattern, not sure if I can adapt this to WPF MVVM

• What job is better for a newbie, one that requires you to create a new program frequently, or something like software maintenance?

  - by MobileDev123

  One of my friends has just completed his college degree and is ready to join the programmers' world. Today he has two offers, one with new projects every time, and another with software maintenance. The remaining factors are not important to him, what he wants to know is which option is better? My experience goes with second option because my first job was the maintenance one and I could learn how my fellow programmers made mistakes while coding . But I soon switched to a new job which required me to create new project every time. I enjoyed both but I must admit that my first job has given me a more advantage today. But it's not necessary that my experience can give benefit to him. But I want to know what is general approach? If I have to give him final verdict on these two, what should I tell him? Edit Everybody deserves one up vote here, I am really learning a lot from you guys.

• how Computer Networks is related to Web/Desktop Java programming

  - by C4CodeE4Exe

  Being a Java programmer , I am wondering how could my work experience would help me learning networking skills. I know C language is used in network socket programming. I know if one knows how to program in one language its not tough to learn another language. Question is I am not able to find much on networks when it comes to Java(may be my knowledge is limited). Do companies like CISCO,TELUS Inc. rely heavily on programmers with such background.

• How do you accept arguments in the main.cpp file and reference another file?

  - by Jason H.

  I have a basic understanding of programming and I currently learning C++. I'm in the beginning phases of building my own CLI program for ubuntu. However, I have hit a few snags and I was wondering if I could get some clarification. The program I am working on is called "sat" and will be available via command line only. I have the main.cpp. However, my real question is more of a "best practices" for programming/organization. When my program "sat" is invoked I want it to take additional arguments. Here is an example: > sat task subtask I'm not sure if the task should be in its own task.cpp file for better organization or if it should be a function in the main.cpp? If the task should be in its own file how do you accept arguments in the main.cpp file and reference the other file? Any thoughts on which method is preferred and reference material to backup the reasoning?

• XNA 4.0 Refresh AudioEngine, WaveBank and Others Not Found

  - by Peteyslatts

  I'm going through the Learning XNA 4.0 book, and unfortunately I installed XNA 4.0 refresh. All the code up until now has worked, with the exception of me needing to remove the Framework.Net and Framework.Storage. (As a side question, will this be problematic later?) The problem I'm having now is that in my Game1.cs file, I have imported all of the XNA.Framework libraries, and when I try and create instances of any of the following classes, an error pops up saying VisualStudio can't find them: AudiEngine, WaveBank, SoundBank, and Cue. I have googled around for a while, and the only solution I saw was to import Microsoft.Xna.Framework.Xact, but this doesn't seem to exist for me. Any help is much appreciated, Thanks Peter.

• Are the famous websites handmade? [closed]

  - by Mithun Chuckraverthy

  I'm a newbie in web designing. I always wanted to build a professional quality website by myself. So, I started learning HTML/XHTML and CSS for presentation; and, JavaScript and PHP/MySQL for scripting. I wonder, would the developers of famous websites design them by hand? Or, have they found out any better idea of using softwares? If so, can you tell me what are they? (By the word famous, I mean any websites that are liked by millions of people all over the world. Like: Google, Facebook etc.) Thanks in advance!

• What would the ultimate developer training class look like?

  - by user652273

  I think today's typical/traditional 3-5 days developer training classes aren't so great, as you tend to forget half of it shortly after. It's too much one way communication and not enough interaction. Also brain research has shown that this kind of setup is usually not optimal for efficient learning. For clarification, I am referring to professional, commercial, paid classes. However this could also be applied for any kind of studies. How could the ultimate developer training package be setup to really make sure you learn what you are supposed to learn? Would that be more: Multimedia? Exercises? Homeworks? Spread out over time instead of 3-5 compact days? Group projects?
