  • Good way of handling class instances in game development?

    - by Bugster
    I'm a new indie game developer, and I've made a few games, but often times when coding I wonder "Is this the way most people do it? Am I doing it wrong?" because I'd like to become a game developer some day, and I really want to get rid of bad practices in time. The way I'm doing it right now is like this: #include <some libraries> #include "Some classes" int main() { Class1 a; Class2 b; Class3 c; a.init(); b.init(); c.init(); // game logic; } Now as I see the game grow, I have more and more classes to initialize and create instances of. This is clean but I'm not sure if this is standard practice. Is this a regular way of creating instances of your game classes or is there a cleaner and more efficient way to do it?

  • is OpenID really that bad?

    - by DoPPler
    I have seen this question on Quora where lots of people seem to agree that OpenID is bad, even going as far as stating that: OpenID is the worst possible "solution" I have ever seen in my entire life to a problem that most people don't really have Then I've seen articles and tweets referencing that question saying that OpenID has lost, and Facebook won. It's sad to read as I quite like the OpenID (or at least idea behind it). I literally hate getting yet another login/password for page (I'll forget it anyway) - it's a pretty serious issue for me and I know lots of people with the same problem. Thus I thought that OpenId is a great solution but I'm not sure anymore. So the question is should I still bother to implement OpenID or it's not worth it? What is the most robust and convenient (from the user perspective) way to identify and authenticate an user?

  • Why don't we store the syntax tree instead of the source code?

    - by Calmarius
    We have a lot of programming languages. Every language is parsed and syntax checked before translated into code so an abstract syntax tree is built. We have this abstract syntax tree, why don't we store this syntax tree instead of the source code (or next to the source code)? By using an AST instead of the source code. Every programmer in a team can serialize this tree to any language, they want (with the appropriate context free grammar) and parse back to AST when they finished. So this would eliminate the debate about the coding style questions (where to put the { and }, where to put whitespace, indentation, etc.) What are the pros and cons of this approach?

  • 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?

  • What steps should be taken to ensure that an open source database gets ready for production?

    - by I_like_traffic_lights
    I am considering using GridSQL in a production environment. However, I do have some indications that it is not ready. One is that it got excluded by the offering of EnterpriseDB a while ago, and the forums seem to report a few wrong results and relatively severe bugs. The alternatives to GridSQL, however cost around 100.000$ to buy, so I was thinking to utilize some of this money to ensure that GridSQL gets ready for production. At the same time, I could risk spending 50.000$ and months of work on the development of GridSQL, just to discover that the design was flawed and that a complete rewrite is needed. Then I would have to buy the commercial alternatives to GridSQL and the existence of my startup would be at risk. Question What steps would you take to ensure that there is as little risk as possible that the worst case scenario described above would happen? It is unrealistic that I could do much testing nor code review/coding myself (I am also not the best developer), so please describe where to find the guys that would need to do the work.

  • Learning PHP MySQL [closed]

    - by Keith Groben
    I've been a designer for several year now. I'm now very interested in learning PHP, MySQL. I've read through W3Schools already and it helped me become familiar. I now want to know where I could go to start building some simple database and php applications so I could be come familiar with coding and start to improve. I think hands on application is the best way to learn. Since I'm a beginner, much of what I've found so far is sort of advanced to me.

  • Want to learn a new language. Not sure which to pick.

    - by Regravity
    I've been coding in Batch, VBS and AutoIt for AGES, and while its been great and I've made some pretty complex desktop applications in AutoIt, I'd like to advance to something that is more flexible / powerful. I've found that I really love programming desktop applications to solve a wide variety of problems which is what I've been doing with AutoIt. I've done a lot of research on different languages, but I'm torn between a few, namely C++, C# and Python. Can anyone suggest which language I should tackle next? And reasons why I should?

  • Windows not shown in Grub after installing 12.10

    - by rowanquigley
    I just installed 12.10 alongside Windows 7. I split my partition into two because disk reader during the installation didn't recognize Windows 7 as being installed on the computer. It installed correctly and I restarted only to find out it wasn't recognized in Grub also and booted straight to Ubuntu. I read this post and thought of using boot-repair would be fine but I gain this error: gpt detected. Please create bios-boot partition (>1MB, unformed filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. I've no idea what it means or what to do next. Suggestions would be appreciated and I have lost my Windows installation disk and I really don't want to have to go looking for it.

  • In 12.04, with my Linksys WUSB54G USB adapter I can see the networks, but cannot connect to any of them

    - by tobye
    I recently loaded Ubuntu version 12.04 onto my computer, and I have a WUSB54G v4 USB wireless adapter. I first tried to get it to work by simply plugging my adapter into an open USB port. This seemed to work fine, it came up with a list of wireless adapters, so I clicked on the correct one and entered the security code. It looked like it was going to connect. It tried for about five minutes before I stopped it. I then decided to create a network as I also have one setup. I did this and it connected, only one problem, I couldn't get onto the internet. Please help me, I am new to Ubuntu and am totally lost.

  • Someone who needs inspiration [on hold]

    - by Anestis
    My apologies if it is not a code problem. However, it is a problem that concerns programming. As a recently graduated Computer Systems Engineering I have gained some basic knowledge with programming using JAVA. I have realised 2 things, the first one is that I realy liked programming and the second is that I am not good at all. More specifically, I struggle on problem solving and when i face complex tasks I feel lost. Every day , I spend some quality time doing simple exercises in order to be more familiar with JAVA. My target is to become a good programmer and find a job on a software company. I am afraid maybe " I dont have it" thats why I am asking you , what should I do? Should i give up? Thanks in advance, Anestis

  • Does a large (hidden) submenu count towards site content in tems of determining page similarities?

    - by Name
    Basically, I have this site that recently lost a lot of traffic after I optimized the html, the exact reasons to which are uncertain. The graph of impressions (times a page appears on search listings) is continuously going down like an e^-x function. Because the content, previously occupying five pages of tables, now fits within a few paragraph tags, the menu now occupies about 80% of the live html code and I am starting to have doubts wherether this affects the "similar pages" factor that Google punishes. Questions: As far as I know, Google ignores invisible material and the submenus are only visible when hovered over. Has anything at all changed in this area? If I ajax in the submenus, leaving only the main eight menu items to load, will I be punished for "hiding" information? Is the idea worth testing or is it frankly retarded?

  • What is the "don't force full gpu scalling" configuration in the newest Nvida driver settings?

    - by wild_oscar
    I have a Zotac Ion board on a computer running Linux ad I had the driver version 295.xx. I was trying to run a 1080 video on XBMC and, because playback was a bit sluggish, part of my (unsuccessful) attempt at making it run smoothly was to upgrade the Nvidia driver. The problem is that the computer is connected by HDMI to a Pioneer A/V system - which in turn is connected to the TV (also through HDMI). When I created this set up I didn't get any image on my tv until I Unchecked "force full gpu scaling" in "Flat Panel Scaling". After upgrading the Nvidia driver I no longer have image. Upon investigating, I saw on the release changelog: Removed Flat Panel Scaling configurability in nvidia-settings. Any desired scaling can be configured through the new "ViewPortIn" and "ViewPortOut" MetaMode attributes. I know very little about this, however, so I'm lost. What would the correct configuration be with these new ViewPortIn/Out options to achieve the same result as "unchecking force full gpu scalling"?

  • Connection make b/w iphone to windows pc-rajay [on hold]

    - by Rajay
    I Need to create connection between ios to windows by using socket programming in ios. I'm trying to to use an application to communicate with Windows via sockets. At the minimum, I'm trying to at least figure out how I can create a connection from the iPhone (maybe using the iPhone to ping the Windows machine?) I'm not really clear on where I need to start. I'm pretty new to iOS development in general, and brand new to socket/network programming. I've tried several tutorials that haven't gotten me far. My goal is: Connect to a server via sockets (the server will be a Windows machine with a service waiting for incoming connections from the iPhone) If possible, I would like to write/build the client piece first, but I have been lost thus far. Hopefully the nice folks in the SO community can lend a hand and point me in the right direction.

  • Windows 8: Paradigm Shift

    You've probably heard a lot about the loss of the Start button in Windows 8. While it isn't completely lost - you can still get to it via a convoluted path - its disappearance is merely a sign of the rethinking that went into the operating system's creation. Window 8's designers made certain assumptions while building the new system: Users will interact with the operating system predominantly through a touch interface. Users will do their computing on mobile devices, and may in fact use several different devices for the same purposes. They may even want to get work done on devices they do n...

  • XNA Load/Unload logic (contentmanager?)

    - by Rhinan
    I am trying to make a point-and-click adventure game with XNA, starting off simple. My experience with XNA is about a month old now, know how the classes and inheritance works (basic stuff). I have a problem where I cannot understand how I should load and unload the textures and game objects in the game, when the player transitions to another level. I've googled this 10 times, but all I find is hard coding while I don't even understand the basics of unloading yet. All I want, is transitioning to another level (replacing all the sprites with new ones). Thanks in advance

    I updated to Ubuntu 12.04 by doing a clean install from a CD. I installed Wine, Q4wine, WineTricks, PlayOnLinux all from the Software Center. After installing Kindle For PC(I ran it in 11.10 as well) Wine doesn't open it. Then I tried to install a game (Eastside Hockey Manager 2007) that I have had Installed on all my previous versions of Ubuntu, again Wine returned an error saying that the installer GUI would not load. So far I'm lost as to why this is happening. Does anyone have an idea?

  • Looking for a previous post about skillsets for an embedded/firmware engineer. Can't find it anymore [closed]

    - by Sandiego
    I remember reading a post inquiring the basic/advanced skills required for embedded engineer works. The top comment divides the answer into two parts, the basic level/design level ,not purely coding(something like this...). Then another level : writing application(all about programming). For each level/category, the top comment talks about the necessary skills/knowledge/college courses(for me at least) . While I was searching for this post as I was trying to read it again, I found similar questions, but these are not the one I saw: http://stackoverflow.com/questions/1091931/what-skill-set-should-a-low-level-programmer-possess http://stackoverflow.com/questions/45247/how-do-i-get-started-in-embedded-programming http://electronics.stackexchange.com/questions/3343/how-to-become-an-embedded-software-developer Has anyone seen the post I'm talking about?

  • Either I'm not confident I just don't know anything [on hold]

    - by zoomerzoom25
    My name is Sael and I'm 14 years old. Since I was 12 and I got my first computer I instantly go interested in making games. So of course like any other I googled it, got discouraged and forgot about it for a few months. When I was 13 I decided to continue programming, and decided that java would best suit me. Now after a year, I have a basic understanding of java and how it works (it just clicked instantly one day). Anyways, my problem is that I know how I'm going to make a simple game in my head, but as soon as I click that "New Project" button on eclipse, I'm instantly lost and can't figure out where to start. I can't do much without a tutorial beside me since my mind is so dependent on it. So here's the question : what can I do to get past this problem of mine, and have any of you felt like this before? sorry if my English is a bit incorrect, Spanish is my main language* I've made Minecraft mods before

  • How do you stay motivated for hobby projects? [closed]

    - by aubreyrhodes
    I started seriously programming as a hobbiest, student and then intern about 4 years ago and I've always done small projects on the side as a learning exercise. Schools over now though, and I spend my days at work as a software developer. I would still love to do projects on the side to learn about areas in computer science that I'm not exposed to at work, but I've noticed that after 8 hours of starring at an IDE it's far to tempting to veg out. Any time I do get up the gumption to work on something for a few hours lately it's gotten left by the wayside. Anyone have any advice for sticking with side projects when you spend most of your day coding?

  • Are there any good javascript libraries for programming with html5 canvas element? [closed]

    - by marko
    I think there are some js-libraries with programming the html5 canvas element. Which one to choose? I've done some js-coding with canvas and are somewhat familiar with the api. But I think somekind of library which encapsulates the somewhat tedious canvas api would be a good thing, so it speeds up the development. Easeljs http://www.createjs.com/#!/EaselJS/download and Paper.js - http://paperjs.org/about/ Anybody who has any experience with any js-libraries for canvas? And any recommendations?
