  • XNA Quadtree with LOD

    - by Byron Cobb
    I'm looking to create a fairly large environment, and as such would like to implement a quadtree and use LOD on it. I've looked through numerous examples and I get the basic idea of a quadtree. Start with a root node with 4 vertices covering the whole map and divide into 4 children nodes until I meet some criteria(max number of triangles) I'm looking for some very very basic algorithm or explanation with respect to drawing the quadtree. What vertices need to be stored per iteration? When do I determine what vertices to draw? When to update indices and vertices? Hope to integrate the bounding frustrum? Do I include parent and child vertices? I'm looking for very simple instruction on what to do. I've scoured the internet for days now looking, but everyone adds extra code and a different spin without explanation. I understand quadtrees, but not with respect to 3d rendering and lod. A link to an outside source will probably have been read by myself already and won't help. Regards, Byron.

  • OWB 11gR2 &ndash; JDBC Helper Utility

    - by David Allan
    One of the common queries when importing the tables via JDBC with 11gR2 is determining why the import wizard doesn’t display the tables that you think it should. I often just use the script below to dump out the schemas, tables and columns that the JDBC driver is returning. This is useful in a few areas; to figure out what the schema name is returned to double check with the schema name you have used in the location (this is used in the DatabaseMetaData.getTables API call within the basic JDBC metadata import. to figure out the data types returned from the JDBC driver when you see columns skipped because of no datatype supported messages. also…I can do it via scripting and don’t need to recompile classes and stuff :-) Edit the tcl script and set the JDBC driver, the connection URL and the username and password (they are at the bottom of the script), the script then calls a basic tcl procedure which writes to standard out the schemas, tables and columns with various properties. For example I executed it using the XML JDBC driver from ODI over a simple customers XML file and it writes the following metadata; You can add more details as you need and execute from the OMBPlus panel within OWB. Download the sample tcl jdbc script here There is a bunch of really useful stuff on OTN documenting this area (start with the white paper here) that is worth checking out all related to the OWB SDK covering everything from platform definitions, custom metadata importers, application adapters, code templates etc. You can find a bunch of goodies on the OWB SDK here.

  • unit/integration testing web service proxy client

    - by cori
    I'm rewriting a PHP client/proxy library that provides an interface to a SOAP-based .Net webservice, and in the process I want to add some unit and integration tests so future modifications are less risky. The work the library I'm working on performs is to marshall the calls to the web service and do a little reorganizing of the responses to present a slightly more -object-oriented interface to the underlying service. Since this library is little else than a thin layer on top of web service calls, my basic assumption is that I'll really be writing integration tests more than unit tests - for example, I don't see any reason to mock away the web service - the work that's performed by the code I'm working on is very light; it's almost passing the response from the service right back to its consumer. Most of the calls are basic CRUD operations: CreateRole(), CreateUser(), DeleteUser(), FindUser(), &ct. I'll be starting from a known database state - the system I'm using for these tests is isolated for testing purposes, so the results will be more or less predictable. My question is this: is it natural to use web service calls to confirm the results of operations within the tests and to reset the state of the application within the scope of each test? Here's an example: One test might be createUserReturnsValidUserId() and might go like this: public function createUserReturnsValidUserId() { // we're assuming a global connection to the service $newUserId = $client->CreateUser("user1"); assertNotNull($newUserId); assertNotNull($client->FindUser($newUserId); $client->deleteUser($newUserId); } So I'm creating a user, making sure I get an ID back and that it represents a user in the system, and then cleaning up after myself (so that later tests don't rely on the success or failure of this test w/r/t the number of users in the system, for example). However this still seems pretty fragile - lots of dependencies and opportunities for tests to fail and effect the results of later tests, which I definitely want to avoid. Am I missing some options of ways to decouple these tests from the system under test, or is this really the best I can do? I think this is a fairly general unit/integration testing question, but if it matters I'm using PHPUnit for the testing framework.

  • Cost effective way to provide static media content

    - by james
    I'd like to be able to deliver around 50MB of static content, either in about 30 individual files up to 10MB or grouped into 3 compressed files, around 5k to 20k times a day. Ideally I'd like to put some sort of very basic security around providing the data to ensure that a request is from the expected source, but if tossing the security for a big reduction in price is possible then it's an option. Does anyone have any suggestions other than what I've found: Google AppEngine is $0.12/GB & I believe has a file size limit of 10MB so I'd have to break the data up a bit. So a rough calculation would seem to be that this would cost me about $30 to $120 a day. Or I've seen something like what seems to be just public static content delivery with no type of logic capabilities like Usenet.nl at what I think calculates to about $0.025/GB which would cost me about $6 to $25 a day. Any idea if I'm going about these calculations right & if there might be a better option for just static content on a decently high volume delivery? Again some basic security would be great but if cost is greatly reduced without it then I'm up for that.

  • What's a good Game development platform for a platformer game with these characteristics?

    - by Joe
    Yes, I know, the best way to make an indie game is to learn to code. I've got some scripting experience, but I want to do worldbuilding with already-existing tools (and communities surrounding those tools), and I've been really impressed with games like An Untitled Story that were made with pre-packaged toolsets at their core, like Game Maker. :) So I'm planning to make my game using either Game Maker or something like it. The basic parameters of my planned game: -2D platformer. -Physics/speed akin to Sonic the Hedgehog. -Large, non-linear world, flowing as seamlessly as possible -- think Super Metroid, but without the forced screen transitions. The first two points have me leaning toward Game Maker -- Plenty of 2D platformers have been made with it, and there are serviceable, openly available Sonic-the-Hedgehog-style physics engines for it that could be adapted to my needs with minimal muss and fuss. But the third makes me antsy -- from what limited information I hear, Game Maker has problems with large levels/boards/screens/whateveryoucallthem, thus necessitating transitions between screens. I want to avoid that if at all possible -- it would, I believe, fundamentally alter the flow of the game. I understand that generally speaking, the more you have loaded into memory the more things are going to chug (especially for a one-size-fits-all game development platform that isn't a model of efficient coding), but I'm hoping there are systems that can un-load objects that are sufficiently far offscreen and thus better produce seamlessness. Any thoughts, people? :) The sooner I can get a basic pre-fab physics engine and world-building program up and running, the sooner I can start prototyping areas and generally tooling around. Should I be looking at Game Maker, or elsewhere? (My current plan is to more-or-less build the game prototype-style, then worry about art and sound at the very end once the damn thing is playable.)

  • Microsoft ADO.NET 4 Step by Step

    - by Sahil Malik
    Ad:: SharePoint 2007 Training in .NET 3.5 technologies (more information). Many years ago, I wrote Pro ADO.NET 2.0. I still think that in the plethora of new data access technologies that have come out since, the basic core ADO.NET fundamentals are still every developer must know, and sadly they do not know. So for some crazy reason, I still see every project make the same data access related mistakes over and over again. Anyway, the challenge is that on top of the core ADO.NET fundamentals, there is a vast array of other new technologies you must learn. The important of which is Entity Framework. So, I was asked to, and I was pleased to be the technical reviewer for Microsoft ADO.NET 4, Step by Step, by Tim Patrick. This book introduces the reader not just to the basic ADO.NET principles, but also Entity Framework, LINQ to SQL, and WCF Data Services. So what you may ask is a SharePoint guy like me doing with such interest in ADO.NET land? Well, that’s what the other side says, what is a hardcore data access sorta guy doing in SharePoint land? :). I have authored/co-authored 4 books so far on data access (1,2,3,4), and one on pure SharePoint, and now one on SharePoint 2010 BI. These are very intertwined topics. And LINQ to SQL and LINQ to SharePoint are almost copy paste of each other. WCF Data services are literally the same in both. And many Entity Framework concepts also apply within SharePoint. So there, I did these both for “interest” reasons. Comment on the article ....

  • What makes a person contribute to opensource? [duplicate]

    - by Jibin
    This question already has an answer here: Why develop free, open source programs? [closed] 14 answers I know this is controversial, but.. There are many great projects like Apache Webserver or Hadoop provided by the OpenSource Community. I often feel that the people that actually benefit (financially), from these projects are developers like me, sitting in India, working for MNCs, who has never contributed anything to any opensource project so far, but earn handsomely due to my basic googling skills & the community provided documentation. Is it fair ? I mean no other industry in the world face such dilemma.Those who work get paid. I mean I almost am starting to feel guilty of taking such advantage of some thing that I contribute nothing to. I had to do projects every semester in college (we could choose projects) & I used to enjoy coding then. I want to contribute. But contributing to opensource is not a task [unlike college or office work]. And life is so busy .. Are all these opensource contributors really jobless ?[just kidding..] Could someone please share some personal experiences on how you guys started contributing or any advice on why I should contribute or what attitude in life makes you keep aside time or is it that you just crazly love writing code or is it that you just love to see your name in the contributors list or do you have a local coding group you hang out with ? Do you feel I am destined to do this ? This is my part of contributing back to the world ? Whats that basic mentality that make you guys want to contribute, while I just want to finish my work and go home. What makes you guys tick ?

  • A new mission statement for my school's algorithms class

    - by Eric Fode
    The teacher at Eastern Washington University that is now teaching the algorithms course is new to eastern and as a result the course has changed drastically mostly in the right direction. That being said I feel that the class could use a more specific, and industry oriented (since that is where most students will go, though suggestions for an academia oriented class are also welcome) direction, having only worked in industry for 2 years I would like the community's (a wider and much more collectively experienced and in the end plausibly more credible) opinion on the quality of this as a statement for the purpose an algorithms class, and if I am completely off target your suggestion for the purpose of a required Jr. level Algorithms class that is standalone (so no other classes focusing specifically on algorithms are required). The statement is as follows: The purpose of the algorithms class is to do three things: Primarily, to teach how to learn, do basic analysis, and implement a given algorithm found outside of the class. Secondly, to teach the student how to model a problem in their mind so that they can find a an existing algorithm or have a direction to start the development of a new algorithm. Third, to overview a variety of algorithms that exist and to deeply understand and analyze one algorithm in each of the basic algorithmic design strategies: Divide and Conquer, Reduce and Conquer, Transform and Conquer, Greedy, Brute Force, Iterative Improvement and Dynamic Programming. The Question in short is: do you agree with this statement of the purpose of an algorithms course, so that it would be useful in the real world, if not what would you suggest?

  • Collision Detection for a 2D RPG

    - by PHMitrious
    First of all, I have done some research on this topic before asking, and I'm asking this question as a mean to get some opinions on this topic, so I don't make a decision only on my own, but taking into account other people's experience as well. I'm starting a 2D online RPG project. I am using SFML for graphics and input and I'm creating a basic game structure and all for the game, creating modules for each part of the game. Well, let me get to the point I just wanted to give you guys some context. I want to decide on how I'm going to work with collision detection. Well I'm kinda going to work on maps with a tile map divided in layers (as usual) and add an extra 2 layers - not exactly in the map - for objects. So I'll have collisions between objects and agents (players - npcs - monsters - spells etc) and agents and tiles. The seconds one can be easily solved the first one need a little bit of work. I considered both creating a basic collision test engine using polygons and a quadtree to diminish tests since I'm going to be working with big maps with lots of objects - creating both a physical and graphical world representation. And I also considered using a physics engine like Box2D for collision tests. I think the first approach would take more work on my part but the second one would have the overhead of using a whole physics engine for just collision detection and no physics. What do you guys think ?

  • How should I make progress further as a programmer?

    - by mushfiq
    Hello, I have just left my college after doing graduation in computer engineering,during my college life I tried to do some freelancing in local market.I succeeded in the last year and earned some small amounts based on joomla,wordpress and visual basic based job.I had some small projects on php,mysql also. After finishing my undergrad life,I sat for an written test for post of python programmer and luckily I got the job and is working there(Its a small software firm do most of the task in python).Day by day I have gained some experience with core python. Meanwhile an USA based web service firm called me for the interview and after finishing three steps(oral+mini coding project+final oral)they selected me(i was wondered!).And I am going to join their with in few days.There I have to work in python(based on Django framework,I know only basic of this framework). My problem is when I started to work with python simultaneously I worked in Odesk as a wordpress,joomla,drupal,php developer. Now a days I am feeling that I am getting "Jack of all trades master of none". My current situation is i am familiar with several popular web technologies but not an expert.I want to make myself skilled. How should I organize myself to be a skilled web programmer?

  • Is micro-optimisation important when coding?

    - by BozKay
    I recently asked a question on stackoverflow.com to find out why isset() was faster than strlen() in php. This raised questions around the importance of readable code and whether performance improvements of micro-seconds in code were worth even considering. My father is a retired programmer, I showed him the responses and he was absolutely certain that if a coder does not consider performance in their code even at the micro level, they are not good programmers. I'm not so sure - perhaps the increase in computing power means we no longer have to consider these kind of micro-performance improvements? Perhaps this kind of considering is up to the people who write the actual language code? (of php in the above case). The environmental factors could be important - the internet consumes 10% of the worlds energy, I wonder how wasteful a few micro-seconds of code is when replicated trillions of times on millions of websites? I'd like to know answers preferably based on facts about programming. Is micro-optimisation important when coding? EDIT : My personal summary of 25 answers, thanks to all. Sometimes we need to really worry about micro-optimisations, but only in very rare circumstances. Reliability and readability are far more important in the majority of cases. However, considering micro-optimisation from time to time doesn't hurt. A basic understanding can help us not to make obvious bad choices when coding such as if (expensiveFunction() && counter < X) Should be if (counter < X && expensiveFunction()) (example from @zidarsk8) This could be an inexpensive function and therefore changing the code would be micro-optimisation. But, with a basic understanding, you would not have to because you would write it correctly in the first place.

    I work with several developers that come from less object oriented background like (VB6, VBA) and are mostly self-taught. As part of moving away from those technologies we recently we started having weekly workshops to go over the features of C#.NET and OO practices and design principles. After a couple of weeks of basic introduction I noticed that they had a lot of problems implementing even basic code. For instance it took probably 15 minutes to implement a Stack.push() and a full hour to implement a simple Stack fully. These developers were trying to do things like passing top index as a parameter to the method, not creating an private array, using variables out of scope. But most of all not going through the "design (dia/mono)log" (I need something to do X, so maybe I'll make an array, or put it here). I am a little confused because they are smart people and are able to produce functional code in their traditional environments. I'm curious if anybody else has encountered a similar thing and if there are any particular resources, exercises, books, ideas that would be helpful in this circumstance.

  • Light mask map and camera for static lights in XNA Platformer

    - by JiminyCricket
    Using the example for some basic light maps found here : http://blog.josack.com/2011/07/xna-2d-dynamic-lighting.html, I've managed to create a lightmap texture using individual lightmaps and display it over a 2D tiled world as in the Platformer example. I'm using the very basic 2D camera example as found here : http://www.david-amador.com/2009/10/xna-camera-2d-with-zoom-and-rotation/, and the problem is that the lightmap texture scrolls with the player sprite. This looks pretty good and would be excellent for lighting the player sprite as it moves. But, I also want to be able to place static lights (or some initial position for the lights) that do not move with the player or camera. When I turn off the camera or give it a static position, it works as a series of static lights so I believe it's probably caused by the camera transformation matrix following the player around. I'm using RenderTarget2Ds, one for the main game screen after all the backgrounds and tiles are rendered, and one for the "lightmap" which consists of a black background and a bunch of lighting textures which are merged with it using additive blending. For now, I'm doing all of this in PlatformerGame.cs where the camera transformation and position is set and the level.Draw() call is made. I can't figure out how to separate the drawing of the lightmap and the camera following the player. I was thinking it would be better to render the shadows and lighting directly in the drawing of the level itself, but I'm not sure how to do that either because this technique requires RenderTarget2Ds and calling SpriteBatch.Begin()/End().

  • What do I need to know to design a language and write a interpreter for it?

    - by alFReD NSH
    I know this question has been asked and even there are thousands of books and articles about it. But the problem is that there are too many, and I don't know are they good enough, I have to design a language and write a interpreter for it. The base language is javascript (using nodejs) but it's ok if the compiler was written in another language that I can use from node. I had done a research about compiler compilers in JS, there is jison (Bison implementaion in JS), waxeye, peg.js. I decided to give jison a try, due to the popularity and its being used by coffee script, so it should be able to cover my language too. The grammar definition syntax is similar to bison. But when I tried read the bison manual it seemed very hard to understand for me. And I think it's because I don't know a lot of things about what I'm doing. Like I don't what is formal language theory. I am experienced in Javascript (I'm more talented in JS than most average programmers). And also know basic C and C++ (not much experience but can write a working code for basic things). I haven't had any formal education, so I may not be familiar with some software engineering and computer science principles. Though everyday I try to grasp a lot of articles and improve. So I'm asking if you know any good book or article that can help me. Please also write why the resource you're suggesting is good. --update-- The language I'm trying to create, is not really complicated. All it has is expressions (with or without units), comparisons and logical operators. There are no functions, loops, ... The goal is to create a language that non-programmers can easily learn. And to write customized validations and calculations.

  • What is a good toy example to teach version control?

    - by janos
    I am looking for practical examples to use when teaching version control. Breaking down the material to basic concepts and providing examples is an obvious way to teach version control, but this can be very boring, unless the examples are really practical or interesting. One idea I have is customizing a wordpress theme. I use wordpress a lot and no theme is ever perfect, so I typically just put the theme directory in version control using any dvcs and start recording changes. The problem with this example is that not many people in the audience may be familiar with wordpress, let alone have shell access to a wordpress site to try out the commands. Preparing a mock site and giving access to everyone is also not an option for me. I need a "toy example" that can be interesting to a broad audience of software developers, and something they can try on their own computers. The tutorial will use a dvcs, but the practical example I'm looking for is only to teach the basic features of version control, ignoring the distributed features for the moment. (Now that I think of it, instead of a mock site, a customized live cd might do the trick...) Any better ideas?

  • Does an inexperienced programmer need an IDE?

    - by Torben Gundtofte-Bruun
    Reading this other question makes me wonder if I (as an absolute beginner PHP programmer) should stick with WAMP and Notepad++ or to switch to some IDE like Eclipse. It's understandable that skilled developers will benefit from a big shiny IDE. But why should an absolute beginner use an IDE? Do the benefits outweigh the extra challenge of learning the IDE on top of learning to develop? Update for clarification: My goal is to get some basic programming experience. By choosing PHP and WAMP (and FogBugz and Kiln) I hope to avoid having to navigate the tricky / messy OS specifics and compiling etc. and just focus on basic functionality like an online user registration form. I've got lots of theoretical understanding from university a decade ago but no practical experience. I want to remedy that with a hobby project that would be similar to a real-world sellable web app. There are so many questions to ask. So many pitfalls I probably have to blunder into. This question is just one piece (my first!) of that puzzle.

  • Complexity of defense AI

    - by Fredrik Johansson
    I have a non-released game, and currently it's only possible to play with another human being. As the game rules are made up by me, I think it would be great if new players could learn basic game play by playing against an AI opponent. I mean it's not like Tennis, where the majority knows at least the fundamental rules. On the other hand, I'm a bit concerned that this AI implementation can be quite complex. I hope you can help me with an complexity estimation. I've tried to summarize the gameplay below. Is this defense AI very hard to do? Basic Defense Game Play Player Defender can move within his land, i.e. inside a random, non-convex, polygon. This land will also contain obstacles modeled as polygons, that Defender has to move around. Player Attacker has also a land, modeled as another such polygon. Assume that Defender shall defend against Attacker. Attacker will then throw a thingy towards Defender's land. To be rewarded, Attacker wants to hit Defender's land, and Defender will want to strike away the thingy from his land before it stops to prevent Attacker from scoring. To feint Defender, Attacker might run around within his land before the throw, and based on these attacker movements Defender shall then continuously move to the best defense position within his land.

  • Using Quickly for text-heavy app

    - by Kevin
    I am trying to create a small app that displays documentation. When it is run, the application window will display a main menu with buttons labeled 'Document 1', 'Document 2', etc. If a user clicks on one of those buttons, the text from the corresponding document will be displayed in the window. Very basic. The text documents range in length from 1000 to 5000 words, and they need basic formatting (bold, italic, maybe one or two font choices). My question is this: what is the best way to store and display long blocks of formatted text, using Quickly? There seems to be a few options: (1) I could load the text blocks into long python strings, (2) I could load the text from text files, or (3) I could somehow copy and paste the formatted text into Glade. In the first two options, I'm not sure how I would format the text (add italic and bold, for instance) once it was loaded. I have experience with PHP/MySQL/HTML/CSS/Javascript, but I'm new to Python. Any help would be appreciated.

  • Groovy Refactoring in NetBeans

    - by Martin Janicek
    Hi guys, during the NetBeans 7.3 feature development, I spend quite a lot of time trying to get some basic Groovy refactoring to the game. I've implemented find usages and rename refactoring for some basic constructs (class types, fields, properties, variables and methods). It's certainly not perfect and it will definitely need a lot fixes and improvements to get it hundred percent reliable, but I need to start somehow :) I would like to ask all of you to test it as much as possible and file a new tickets to the cases where it doesn't work as expected (e.g. some occurrences which should be in usages isn't there etc.) ..it's really important for me because I don't have real Groovy project and thus I can test only some simple cases. I can promise, that with your help we can make it really useful for the next release. Also please be aware that the current version is focusing only on the .groovy files. That means it won't find any usages from the .java files (and the same applies for finding usages from java files - it won't find any groovy usages). I know it's not ideal, but as I said.. we have to start somehow and it wasn't possible to make it all-in-one, so only other option was to wait for the NetBeans 7.4. I'll focus on better Java-Groovy integration in the next release (not only in refactoring, but also in navigation, code completion etc.) BTW: I've created a new component with surprising name "Refactoring" in our bugzilla[1], so please put the reported issues into this category.

  • Regulation of the software industry

    - by Flexo
    Every few years someone proposes tighter regulation for the software industry. This IEEE article has been getting some attention lately on the subject. If software engineers who write programs for systems that expose the public to physical or financial risk knew they would be tested on their competence, the thinking goes, it would reduce the flaws and failures in code—and maybe save a few lives in the bargain. I'm skeptical about the value and merit of this. To my mind it looks like a land grab by those that proposed it. The quote that clinches that for me is: The exam will test for basic knowledge, not mastery of subject matter because the big failures (e.g. THERAC-25) seem to be complex, subtle issues that "basic knowledge" would never be sufficient to prevent. Ignoring any local issues (such as existing protections of the title Engineer in some jurisdictions): The aims are noble - avoid the quacks/charlatans1 and make that distinction more obvious to those that buy their software. Can tighter regulation of the software industry ever achieve it's original goal? 1 Exactly as regulation of the medical profession was intended to do.

  • How to convince a client to switch to a framework *now*; also examples of great, large-scale php applications.

    - by cbrandolino
    Hi everybody. I'm about to start working on a very ambitious project that, in my opinion, has some great potential for what concerns the basic concept and the implementation ideas (implementation as in how this ideas will be implemented, not as in programming). The state of the code right now is unluckily subpar. It's vanilla php, no framework, no separation between application and visualization logic. It's been done mostly by amateur students (I know great amateur/student programmers, don't get me wrong: this was not the case though). The clients are really great, and they know the system won't scale and needs a redesign. The problem is, they would like to launch a beta ASAP and then think of rebuilding. Since just the basic functionalities are present now, I suggested it would be a great idea if we (we're a three-people shop, all very proficient) ported that code to some framework (we like CodeIgniter) before launching. We would reasonably be able to do that in < 10 days. Problem is, they don't think php would be a valid long-term solution anyway, so they would prefer to just let it be and fix the bugs for now (there's quite a bit) and then directly switch to some ruby/python based system. Porting to CI now will make future improvements incredibly easier, the current code more secure, changing the style - still being discussed with the designers - a breeze (reminder: there are database calls in template files right now); the biggest obstacle is the lack of trust in php as a valid, scalable technology. So well, I need some examples of great php applications (apart from facebook) and some suggestions on how to try to convince them to port soon. Again, they're great people - it's not like they would like ruby cause it's so hot right now; they just don't trust php since us cool programmers like bashing it, I suppose, but I'm sure going on like this for even one more day would be a mistake. Also, we have some weight in the decision process.
