• Does your team develop their supporting tools or this should be outsourced out of it?

  - by Pierre 303

  By supporting tools, I mean: reference data manager, like virus definition for anti-virus software test data generator level builders for games simulators or advanced mocking systems Does the team building the core product (in the case above, the game or the anti-virus) should be part of the development of the supporting tools significantly, or this is a task you would outsourced out of the team to help it focus on the product? I don't have enough experience to evaluate the pros & cons of each, so I'm hopping you would come up with personal experiences to share, or even studies or papers you read on the subject.

• Am I violating LSP if the condition can be checked?

  - by William

  This base class for some shapes I have in my game looks like this. Some of the shapes can be resized, some of them can not. private Shape shape; public virtual void SetSizeOfShape(int x, int y) { if (CanResize()){ shape.Width = x; shape.Height = y; } else { throw new Exception("You cannot resize this shape"); } } public virtual bool CanResize() { return true; } In a sub class of a shape that I don't ever want to resize I am overriding the CanResize() method so a piece of client code can check before calling the SetSizeOfShape() method. public override bool CanResize() { return false; } Here's how it might look in my client code: public void DoSomething(Shape s) { if(s.CanResize()){ s.SetSizeOfShape(50, 70); } } Is this violating LSP?

• Can I rightfully claim this as my own project if I recieved help online?

  - by Brad Guy

  Basically I'm new to network programming in Python, so I went on a tutorial online to find out about it. Using what was taught in the tutorial (creating a socket, connecting to ports, etc), I modified the code so that I made a program where two computers can send messages to one another. If I were to apply for a job and show this to my interviewers, would the code for it technically be mine? It is fair to say that I didn't modify the code by that much; However, what if for example I modified it into something like a tic-tac-toe game, where two users play each other from different PCs, would the code then be mine? I just don't want to look like a plagiarizer hence why I ask.

  - by Shaun

  I am facing a error in Java using the method Loops. I am a basic user learning Java and I am following a book with teaches you the basics of Java.

• How to balance programming projects between feasibility and usefulness

  - by tyjkenn

  I've become fairly competent as a programmer, but I would not say I am a master. I work independently, most as a hobby, although I have done some freelance PHP work. I tend to find myself dabbling in a lot of things: Java Android SDK, Arduino, game scripting, Lua, etc. I've reached the point where I want to start a real software project, but cannot think of a small enough project that allows me enough practice, while still being able to publish a decent piece of software in a reasonable amount of time, and build up a portfolio. More specifically, I was looking at Ubuntu development, in Python, using the Quickly toolset, which includes the PyGTK libraries. So the question is, what is the best way to come up with a small project that is still useful, as a starting point to a software development career?

• Want to use h264 in my commercial program. What steps should i take?

  - by Jason123

  Want to use h264 in my commercial program. What steps should I take? Here is what I see that needs to be done. I need to buy a license from VideoLan (x264licensing.com) to use the library to encode video into h264 format and I need to buy a license from the MpegLAGroup to use the h264 video encoding in general in my commercial product. Am I right in thinking that? How much do these cost? I don't see selling much since my target is very niche (video game screen capturing).

• How can I format my active hard drive to NTFS?

  - by Ghost

  Believe it or not, I'm not too happy with Ubuntu. Well, let me rephrase that. I like it, but the only thing I don't like about it is that it's too much of a hassle to get a game to work. I'm trying to install Windows 7 with a 4GB flash drive, but my error that comes up is that my hard drive I'm trying to install on is in ext4. I need to format it to read NTFS. I can't seem to find any topics on how to format an active hard drive. I found a topic that explains how to move Ubuntu to a new drive, but it's a bit confusing to me. Please help! (Please don't disregard this topic just because I want to go back to windows)

• E-Commerce Website

  - by haargott

  I am planning to create an e-commerce website for users to buy products and services. In this website I want users to register and also participate in something like a browser game, where every user may receive some questions which they have to answer. For each question they successfully answered, they receive points and the number of collected points will decide on which rank they are. Edit 2 Currently I am considering using only HTML, CSS, JavaScript, PHP, SQL to design this e-commerce website. Together with this I was thinking about learning jQuery as it may help me, but I am not sure if I should code everything specifically by myself or just use the library to make it faster. 1) Could you tell me if those languages are sufficient enough for creating such a website described? 2) Could you tell me what kind of free software tools and frameworks are most appropriate to use when creating this e-commerce website?

• Anti-depressant and programming

  - by user12358

  I wanted to ask your opinion on anti-depressants, since I took them daily for 3 years now, but I can't be sure if I'm less perfomant with them or without, since I never withdrawed. I'm still at school at the age of 25, still having some motivation problems (for example I can't get used to do something at school if I don't think it will teach me something), but I'm quite motivated to work in the video-game field, since I have some personnal projects in mind. I know C++ programming etc, I'm still learning techniques, but do you think I should try more to do my project instead of just following the work I'm assigned to ? Have you had experience with depression or anti-depressants ? How did it affect your work ? Do you think that being depressed or half-depressed can improve creativity ?

• How to learn to translate real world problems to code?

  - by StudioWorks

  I'm kind of a beginner to Java and OOP and I didn't quite get the whole concept of seeing a real world problem and translating it to classes and code. For example, I was reading a book on UML and at the beginning the author takes the example of a tic tac toe game and says: "In this example, it's natural to see three classes: Board, Player and Position." Then, he creates the methods in each class and explains how they relate. What I can't understand is how he thought all this. So, where should I start to learn how to see a real world problem and then "translate" it into code?

• Minecraft not working on Ubuntu 11.10, Java 7

  - by user71007

  I got into Minecraft 2 months ago and just today I switched to Ubuntu. I downloaded Java from the special script (http://www.duinsoft.nl/packages.php?t=en) and after I verified it said it was installed. So I downloaded the Minecraft.jar file and ran it through the Java runtime. It updated like the launcher should... ... And it froze. Went black, didn't even get to the Mojang screen. Please help me! Minecraft is my favorite game and I can't stand to lose it.

• Minecraft program frame rate is very slow

  - by Cade

  I have recently downloaded Minecraft to Ubuntu 12.04. It launches and plays successfully, however- the frame rates for the game are extremely slow. They never go past 9 fps and usually drop below 3 fps. I have been a Windows XP user for years and have just recently switched to Ubuntu, so I'm not an expert with this OS. My video card is a Diamond Stealth s60 with Radeon 7000. I don't know what other information you guys need but if you ask for it, and would please tell me how to get to it, I will tell you as soon as I can. Thanks for your help.

• Pattern for loading and handling resources

  - by Enoon

  Many times there is the need to load external resources into the program, may they be graphics, audio samples or text strings. Is there a patten for handling the loading and the handling of such resources? For example: should I have a class that loads all the data and then call it everytime I need the data? As in: GraphicsHandler.instance().loadAllData() ...//and then later: draw(x,y, GraphicsHandler.instance().getData(WATER_IMAGE)) //or maybe draw(x,y, GraphicsHandler.instance().WATER_IMAGE) Or should I assign each resource to the class where it belongs? As in (for example, in a game): Graphics g = GraphicsLoader.load(CHAR01); Character c = new Character(..., g); ... c.draw(); Generally speaking which of these two is the more robust solution? GraphicsHandler.instance().getData(WATER_IMAGE) //or GraphicsHandler.instance().WATER_IMAGE //a constant reference

• 12.04 - sound is laggy when running games through Wine

  - by orzechowskid

  Lenovo U400 Wine 1.5.5 Ubuntu 12.04 with all updates applied I'm experiencing severe (~500ms) audio lag in all games run in Wine. Portal 2, Half-Life, World of Goo, and Fallout are all exhibiting this problem. When I run winecfg though and click the "Test Sound" button at the bottom of the Audio tab, the sound effect appears to play immediately. So I'm not sure what's going on. I don't think it's a problem with PulseAudio by itself since totem videos and Youtube clips both play in perfect sync. Anyone have any ideas on where to start fixing this? thanks! (edit: I thought this was limited to Steam games but I installed a non-Steam game and I now see that's not the case. I get audio lag in other apps too.)

• How to find a programming mentor?

  - by Dvole

  I decided to learn programming. I've been reading SO for few days, and I think I will start with C++, as I read some articles. I am aware of loops, arrays, program logic and objects a little and I need someone to look me over and help me with small questions I get when doing my first projects. So here is the question - where do I find such guy? I don't got any friends who program and all. EDIT: 2 years later, I am still looking for mentor. I did not actively code just started 3 months again. I work on Objective-C and iOS programming and game programming with Cocos2d. If you want to become my mentor, drop me a or comment.

• Why do so many people dislike C++?

  - by General K

  Beginners and professional, on blogs, in forums and chatrooms - people say it everywhere: C++ oh dear god no The short form of the question: For what reason is C++ so widely disliked and people are horrified by the imagination of using it for some project? I have been using a lot of different languages, including C++ by now, and I can only say that I really like it. I'm far more horrified by Delphi than by C++. Actually, I find it's an almost perfect, compiled language! I've been doing a lot of different projects in C++ as well, ranging from 3D video games to webservers and emulators for old video game consoles. And I still do not see the problem everyone else seems to have with it! It was hard for me to get into it of course, as it is quite complex and has a lot of depth, but after that it's simply great.

• And again... VMware Player 4.0.4 on Ubuntu 12.04 (Precise Pangolin)

  Even with the new version of VMware Player 4.0.4 you are still required to patch their sources. So, same game as last month. Just changing the value of the required version in the kernel patch script of Stefano Angeleri (weltall) and you are done: nano patch-modules_3.2.0.sh Please change line 8 at the top of the script like so: plreqver=4.0.4 Save your modification and then run the following commands: sudo rm /usr/lib/vmware/modules/source/.patchedsudo ./patch-modules_3.2.0.shsudo service vmware restart And again, on first start VMware will present you their EULA which you have to accept, and everything gets back to normal operation mode. Interestingly, one day ago the Ubuntu repositories provided a newer kernel version 3.2.0-25, so everything is running fine for now.

• Which is better? Native App or hybrid App?

  - by Prabakaran

  I want to develop a simple App for iOS, Android and windows phone. I just wondered that a simple HTML5, JS and CSS combination can work in all of these platforms. I want to know which one will be efficient? No problem with time and coding. But if i can achieve everything with HTML5-JS itself, i will chose Hybrid development. I want to know the major difference between the Native and Hybrid Development with example(I know that the main difference is HTML5-JS supports cross platform). Note : I am not making a game app.

• Microsoft Unveils Xbox SmartGlass

  SmartGlass won't be available to consumers until the fall, and if the reviews of the feature's capability are any indication, it's going to feel like a very long wait. SmartGlass lets you switch from watching something on your TV to watching it on your tablet or smartphone, and vice versa. But that's only the beginning. SmartGlass also lets developers turn smartphones and tablets into Xbox 360 controllers. Thus, if you're playing a sports-based game with your friends, you can enter your strategic plays into your smartphone, so he can't tell what your team is about to do. Or, with a baseball ga...

• Can I set command line executed games to open in a window instead of fullscreen?

  - by ajwhitaker822

  I really enjoy some of the free Linux games and just downloaded Cave Story, one of my all-time favorites. However, I can only play the game in full screen, 800X600 Resolution. I was wondering if I could run this program in a window instead of full screen. Is there a command or Unity plugin to do this? Also, would the same work to run SuperTux in a window as well? I'm running 12.04 if that makes any difference. Thanks for your help.
