  • How can I make video games if I don't like programming?

    - by hoper
    I am studying C++ code in my school (my major is computer programming). Honestly, my grades are not so good, and assignments are really hard. Sometimes I feel sad that I will spend 8-10 hours per day coding (which is stressful) in the future for my job. But I still want to make video games. Maybe this is the only reason why I am taking all of these stressful courses. I always write down plots, stories, characters, fictional gaming worlds... Once, I thought I should study artistic technology such as game design and not computer technology such as C++, C#, etc. However, most of popular game designers (or directors) such as Kojima, Miyamoto, etc. used to be good programmers. Companies actaully assign programmers to directors because they understand how to make a game. I've try to find other colleges or universities where they teach game design programs. However, one article that lists rank 10 game design schools in North America seems untrustful because the survey company only scores it from intervews of students. Once, I tried to attend Art Institute of Vancouver which is rank 7 according to that article. However, one programmer who used to be an instructor in there told me the truth: the employement rate of graduated students is low. How can I have a future making games if I don't like programming?

  • DAO/Webservice Consumption in Web Application

    - by Gavin
    I am currently working on converting a "legacy" web-based (Coldfusion) application from single data source (MSSQL database) to multi-tier OOP. In my current system there is a read/write database with all the usual stuff and additional "read-only" databases that are exported daily/hourly from an Enterprise Resource Planning (ERP) system by SSIS jobs with business product/item and manufacturing/SCM planning data. The reason I have the opportunity and need to convert to multi-tier OOP is a newer more modern ERP system is being implemented business wide that will be a complete replacement. This newer ERP system offers several interfaces for third party applications like mine, from direct SQL access to either a dotNet web-service or a SOAP-like web-service. I have found several suitable frameworks I would be happy to use (Coldspring, FW/1) but I am not sure what design patterns apply to my data access object/component and how to manage the connection/session tokens, with this background, my question has the following three parts: Firstly I have concerns with moving from the relative safety of a SSIS job that protects me from downtime and speed of the ERP system to directly connecting with one of the web services which I note seem significantly slower than I expected (simple/small requests often take up to a whole second). Are there any design patterns I can investigate/use to cache/protect my data tier? It is my understanding data access objects (the component that connects directly with the web services and convert them into the data types I can then work with in my Domain Objects) should be singletons (and will act as an Adapter/Facade), am I correct? As part of the data access object I have to setup a connection by username/password (I could set up multiple users and/or connect multiple times with this) which responds with a session token that needs to be provided on every subsequent request. Do I do this once and share it across the whole application, do I setup a new "connection" for every user of my application and keep the token in their session scope (might quickly hit licensing limits), do I set the "connection" up per page request, or is there a design pattern I am missing that can manage multiple "connections" where a requests/access uses the first free "connection"? It is worth noting if the ERP system dies I will need to reset/invalidate all the connections and start from scratch, and depending on which web-service I use might need manually close the "connection/session"

  • Today I talk about you

    - by BuckWoody
    Some time back I posted a blog entry (mirrored here and here) asking you how you design databases. Out of those responses, my own experience, studies I read, and interviews I conducted, I collected a wealth of data. Thanks for your responses. So what am I going to do with that information? Well, all along I had planned for that to be used today. I am giving a presentation at an event called “TechReady” called “How Your Customers Design Databases”. This is a Microsoft-internal event, where technical professionals like myself, salespeople, and the product team get together to talk about what has been working, what doesn’t, what is coming and hopefully (fingers crossed here) what the product team can do to help us help the SQL Server community. I’ve mentioned before that I teach database design as part of a course I run at the University of Washington. I’m also planning to give a mini-lecture from that series at TechEd 2010, so if you’re coming stop by. I’d love to meet you. So today I talk about you – thanks for the input. I hope you and I can make a difference in the product. Might take a while, but it’s nice to know your voice is being heard.

  • Can I become a Game Designer? [on hold]

    - by user32721
    This is my first time posting something on a forum in 4 years. I am posting this because I want to adjust my expectations and goals regarding game design. I am in college in Morocco (Al Akhawayn university). just started my junior year. I am a communications major (school of humanities) and a gender studies minor. I want to become a video game designer. It is the only career that I am interested in. I have been playing ever since I was 5 and haven't stopped yet. Currently I don't have any noteworthy skills to become a designer. I don't know how to program (don't really have the patience for it) and I can't draw to save my life. I haven't tried visual software like MAYA or MAX so I can't comment on graphic design. So I basically want to know whether my current education is capable of helping me reach my goal. If not then should I take a master's in game design (in the U.S?) or switch my minor to computer science? I am sorry that this post is long! I look forward to hearing your advice!

  • Library Organization in .NET

    - by Greg Ros
    I've written a .NET bitwise operations library as part of my projects (stuff ranging from get MSB set to some more complicated bitwise transformations) and I mean to release it as free software. I'm a bit confused about a design aspect of the library, though. Many of the methods/transformations in the library come with different endianness. A simple example is a getBitAt method that regards index 0 as the least significant bit, or the most significant bit, depending on the version used. In practice, I've found that using separate functions for different endianness results in much more comprehensible and reusable code than assuming all operations are little-endian or something. I'm really stumped regarding how best to package the library. Should I have methods that have LE and BE versions take an enum parameter in their signature, e.g. Endianness.Little, Endianness.Big? Should I have different static classes with identically named methods? such as MSB.GetBit and LSB.GetBit On a much wider note, is there a standard I could use in cases like this? Some guide? Is my design issue trivial? I have a perfectionist bent, and I sometimes get stuck on tricky design issues like this... Note: I've sort of realized I'm using endianness somewhat colloquially to refer to the order/place value of digital component parts (be they bits, bytes, or words) in a larger whole, in any setting. I'm not talking about machine-level endianness or serial transmission endianness. Just about place-value semantics in general. So there isn't a context of targeting different machines/transmission techniques or something.

  • Best practice for combining a Java Applet/ Android interface?

    - by Pearsonartphoto
    I'm working on an online game, which I am seriously considering writing a Java Applet for it. The game is not overly complex on the features. I'm considering at some point having at least 3 versions of the game, which include a Java stand alone, applet, and Android game. I know from Design Patterns that the best way to use differing things like buttons and the like is to use a Bridge interface, where I have a common template for the common buttons. However, I'm having a bit of difficulty understanding what to do about the following. I know that Android programs use an Activity structure, which I am well familiar with, and that Applets extend the Applet interface, which I am not as familiar with. I also know that a stand alone java program uses basically a main() function, which doesn't have much structure. I'm convinced that there should be a way to design a common design pattern between the two, but somehow I'm missing what that is exactly. What can I do to make the different frameworks work with as much common code as possible?

  • Is there a better strategy than relying on the compiler to catch errors?

    - by koan
    I've been programming in C and C++ for some time, although I would say I'm far from being an expert. For some time, I've been using various strategies to develop my code such as unit tests, test driven design, code reviews and so on. When I wrote my first programs in BASIC, I typed in long blocks before finding they would not run and they were a nightmare to debug. So I learned to write a small bit and then test it. These days, I often find myself repeatedly writing a small bit of code then using the compiler to find all the mistakes. That's OK if it picks up a typo but when you start adjusting the parameters types etc just to make it compile you can screw up the design. It also seems that the compiler is creeping into the design process when it should only be used for checking syntax. There's a danger here of over reliance on the compiler to make my programs better. Are there better strategies than this? I vaguely remember some time ago an article on a company developing a type of C compiler where an extra header file also specified the prototypes. The idea was that inconsistencies in the API definition would be easier to catch if you had to define it twice in different ways.

  • How to maintain PCI compliance on a LAMP server when repositories don't keep up with versions

    - by Jared Green
    We run Ubuntu Lucid 10.0.4 as the foundation of our LAMP environment. We are trying to become PCI compliant so that we can pass CC info through our server. We have run some third-party scans on our servers to begin the certification process and have run into errors regarding PHP 5 versions and Apache versions. The latest PHP version hosted in our official lucid repository is about 10 versions lower than what PCI compliance requires. How do we upgrade to stay current with PCI compliance requirements? We need to get from php 5.3.2 to php 5.3.15 As well as up to apache 2.2.23 I've searched far and wide for an answer and haven't come up with a realistic answer. Some recommend compiling manually - which sounds like a nightmare, and others recommend a PPA - which sounds insecure. What should we do?

  • Mercurial mirror: abort: No such file or directory: http://[...]/00manifest.i

    - by Sridhar Ratnakumar
    I am trying to setup a daily mirror of a mercurial repository - code.python.org in particular - within our local network, and serve that via Apache HTTPD. On the remote host that hosts apache, I did this: $ cd /var/www $ hg clone http://code.python.org/hg/trunk/ On my macbook, I ran: $ hg -v clone http://remote/trunk/ (falling back to static-http) abort: No such file or directory: http://remote/trunk/.hg/store/00manifest.i Google does not show any relevant result for this particular error. I remember back in those days being able to setup Bazaar mirrors by a simple clone. Doesn't Mercurial work like that? How do I setup a mirror that must further act like a clone URL?

  • XNA Moddable Game - Architecture Design and Reflection

    - by David K
    I've decided to embark on an XNA moddable game project of a simple rogue style. For all purposes of this question, I'm going to not be using a scripting engine, but rather allow modders to directly compile assemblies that are loaded by the game at run time. I know about the security problems this may raise. So in order to expose the moddable content, I have gone about creating a generic project in XNA called MyModel. This contains a number of interfaces that all inherit from IPlugin, such as IGameSystem, IRenderingSystem, IHud, IInputSystem etc. Then I've created another project called MyRogueModel. This references MyModel project, and holds interfaces such as IMonster, IPlayer, IDungeonGenerator, IInventorySystem. More rogue specific interfaces, but again, all interfaces in this project inherit from IPlugin. Then finally, I've created another project called MyRogueGame, that references both MyModel and MyRogueModel projects. This project will be the game that you run and play. Here I have put the actual implementation of the Monster, DungeonGenerator, InputSystem and RenderingSystem classes. This project will also scan the mods directory during run time and load any IPlugins it finds using reflection and override anything it finds from the default. For example if it finds a new implementation of the DungeonGenerator it will use that one instead. Now my question is, in order to get this far, I have effectively 2 projects that contain nothing but interfaces... which seems a little... strange ? For people to create mods for the game, I would give them both the MyModel and MyRogueModel assemblies in which they would reference. I'm not sure whether this is the right way to do it, but my reasoning goes as follows : If I write 1 input system, I can use it in any game I write. If I create 3 rogue like games, and a modder writes 1 rendering system, that modder could use the rendering system for all 3 games, because it all comes from the MyModel project. I come from a more web based C# role, so having empty interface projects doesn't seem wrong, its just something I haven't done before. Before I embark on something that might be crazy, I'd just like to know whether this is a foolish idea and whether there's a better (or established) design principle I should be following ?

  • Trying to create a git repo that does an automatic checkout everytime someone updates origin

    - by Dane Larsen
    Basically, I have a server with a git repo 'origin'. I'm trying to have another repo auto-pull from origin every time someone pushes code to it. I've been using the hooks in origin, specifically post-receive. So far, my post receive looks something like this: #!/bin/sh GIT_DIR=/home/<user>/<test_repo> git pull origin master But when I push to origin from another computer, I get the error: remote: fatal: Not a git repository: '/home/<user>/<test_repo>' However, test_repo most definitely is a git repo. I can cd into it and run 'git pull origin master' and it works fine. Is there an easier way to do what I'm trying to do? If not, what am I doing wrong with this approach? Thanks in advance. Edit, to clarify: The repo is a website in progress, and I'd like to have a version of it available at all times that is fully up to date.

  • UI Design Patterns : Are you developing a Fusion Apps extension, an ADF or Webcenter App?

    - by asantaga
    A big question I get asked when speaking to partners who are developing Oracle ADF, or Webcenter, Apps is how to make it look nice.. Some of the big SIs ask me, "Do we have any design patterns/guidelines we can use?". .. Alas website design is a very personal thing and each website will have different requirements and needs, however I am now pleased to say we've just launched "Oracle Fusion Applications Design Patterns" website.   The website is the result of many years of Oracle R&D into user interface design for Fusion applications and features a really cool web app which allows you to visualise the UI components in action. Although many of the design patterns are related to ADF , its worth noting that ADF took its lead from Oracle Fusion Applications User Interface needs - not the other way around, its just taken us a while to publish these. Coupled together with the dashboard patterns this makes are really cool extra asset for your kit bag Design Patterns Oracle dashboard patterns and guidelines Usable Apps.oracle.com Enjoy

  • Why and when to use Personal Package Archives (PPA)

    - by reversiblean
    Do you prefer PPA over core repositories and why or why not? Are there any compatibility issues when using a PPA as there are different distro releases but just one common repository? Where would you normally search for application repositories that are not in the core repositories? I.e., I was about to install Gnome Flashback in Ubuntu 12.04 which is the new classic version of earlier fallback but found that it's only available as a ppa-release and was wondering which one to choose between the two; fallback or newer flashback.

  • Remove file from git repository (history)

    - by Devenv
    (solved, see bottom of the question body) Looking for this for a long time now, what I have till now is: http://dound.com/2009/04/git-forever-remove-files-or-folders-from-history/ and http://progit.org/book/ch9-7.html Pretty much the same method, but both of them leave objects in pack files... Stuck. What I tried: git filter-branch --index-filter 'git rm --cached --ignore-unmatch file_name' rm -Rf .git/refs/original rm -Rf .git/logs/ git gc Still have files in the pack, and this is how I know it: git verify-pack -v .git/objects/pack/pack-3f8c0...bb.idx | sort -k 3 -n | tail -3 And this: git filter-branch --index-filter "git rm -rf --cached --ignore-unmatch file_name" HEAD rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune The same... Tried git clone trick, it removed some of the files (~3000 of them) but the largest files are still there... I have some large legacy files in the repository, ~200M, and I really don't want them there... And I don't want to reset the repository to 0 :( SOLUTION: This is the shortest way to get rid of the files: check .git/packed-refs - my problem was that I had there a refs/remotes/origin/master line for a remote repository, delete it, otherwise git won't remove those files (optional) git verify-pack -v .git/objects/pack/#{pack-name}.idx | sort -k 3 -n | tail -5 - to check for the largest files (optional) git rev-list --objects --all | grep a0d770a97ff0fac0be1d777b32cc67fe69eb9a98 - to check what files those are git filter-branch --index-filter 'git rm --cached --ignore-unmatch file_names' - to remove the file from all revisions rm -rf .git/refs/original/ - to remove git's backup git reflog expire --all --expire='0 days' - to expire all the loose objects (optional) git fsck --full --unreachable - to check if there are any loose objects git repack -A -d - repacking the pack git prune - to finally remove those objects

  • Adding changes from one Mercurial repository to another

    - by Patrik Hägne
    When changing the VCS for my project FakeItEasy from SVN to Mercurial on Google Code I was a bit too eager (I'm funny like that). What I did was just checking the latest version out of SVN and then commiting that checkout as the first revision of the new Mercurial repo. This obviously has the effect that all history is lost. Later when getting a bit better acustomed to Mercurial I realized that there is such a thing as a "convert extension" that allows you to convert a SVN repo into a Mercurial repo. Now what I want to do is to convert the old SVN repo and then have all change sets from the currently existing Mercurial repo imported into this converted repo except the very first commit to Mercurial. I've converted the SVN repo to a local Mercurial repo but now is when I'm stuck. I thought I'd be able to use the convert extension to bring the current Mercurial repository into the converted one and having a splice map remove the first commit but I can not seem to get this to work. I've also tried to just use convert without splice map to get all change sets from the current Mercurial repo into the converted one and the rebase the second version in the current to the last commit from the old SVN repository but I can't get that to work either. To make this clearer lets say I have these two repositories: A: revA1-revA2 B: revB1-revB2-revB3 (Where revB1 is actually a copy of revA2) Now I want to combine these two into the new repository containing this: C: revA1-revA2-revB2-revB3

  • Copying a foreign Subversion repository to keep under dependencies

    - by Jonathan Sternberg
    I want to keep dependencies for my project in our own repository, that way we have consistent libraries for the entire team to work with. For example, I want our project to use the Boost libraries. I've seen this done in the past with putting dependencies under a "vendor" or "dependencies" folder. But I still want to be able to update these dependencies. If a new feature appears in a library and we need it, I want to just be able to update that repository within our own repository. I don't want to have to recopy it and put it under version control again. I'd also like for us to have the ability to change dependencies if a small change is needed without stopping us from ever updating the library. I want the ability to do something like 'svn cp', then be able to 'svn merge' in the future. I just tried this with the boost trunk, but I'm not able to get any history using 'svn log' on the copy I made. How do I do this? What is usually done for large projects with dependencies?

  • Setting up a git repository on a server

    - by lostInTransit
    Hi I had posted this question on superuser but didn't get a helpful response. Thought I'd try here since the question does deal with some configurations and settings for using github. I have a central server with SSO installed. All my machines are connected through the lan to this server. I have also setup a remote git repository on this server. Now what I'd like to do is make the server act as a central repository. All my employees can commit their code to the server and the server pushes it to the remote git repository. Can someone please help me out with this process? I am new to git and still learning how to use it effectively. So a step-by-step process or an existing document which I can refer to for this? Also can I integrate it with SSO in any way? The server itself is setup on a Mac and SSO uses Atlassian Crowd. Thanks.

  • Arranging VS2008 generated LinqToSql/EntityFramework data models/contexts in assemblies.

    - by JMSA
    What pattern should I use for data-access in case of VS2008 generated L2s or EF DataModels? Repository-pattern or what? As we know VS2008 generates Data-Models and DataContexts/ObjectContexts in the same file, then, how should I arrange my VS2008 assemblies in my VS2008 solution to achieve a layered design? If I use repository pattern, how should I arrange my assemblies in the VS2008 solution (as Data-Models and Data/Object-Contexts are stored in the same file...)? Any web/example link would be appreciated.
