  • I'm a premature optimizer

    - by Matthew Day
    I work in a small sized software/web development company. I have gotten into the habit of optimizing prematurely, I know it is evil and promotes bad code... But I have been working at this firm for a long while and I have deemed this as a necessary evil. It has never caused me an issue so far in the past, but it might if I get partners or a successor. The point of this long-winded speech is that, should I change my evil practices to 'save face' and to help out in the future?

  • How to design a game engine in an object-oriented language?

    - by chuzzum
    Whenever I try and write a game in any object-oriented language, the first problem I always face (after thinking about what kind of game to write) is how to design the engine. Even if I'm using existing libraries or frameworks like SDL, I still find myself having to make certain decisions for every game, like whether to use a state machine to manage menus, what kind of class to use for resource loading, etc. What is a good design and how would it be implemented? What are some tradeoffs that have to be made and their pros/cons?

  • Les CPU monocoeur des smartphones et tablettes sont-ils assez puissants ? NVIDIA souhaite mettre plus de coeurs dans ces appareils

    Les CPU monocoeur des smartphones et tablettes sont-ils assez puissants ? Non répond Nvidia, qui souhaite implémenter plus de coeurs dans ces appareils Pour Nvidia, "les processeurs dual-core seront le standard en 2011, et les quad-core ne tarderont pas à suivre". L'entreprise trouve en effet que les appareil mobiles, actuellement équipés de puces à un seul coeur, ne sont pas assez puissants. Pourtant, on leur en demande toujours plus, notamment de nos jours avec l'arrivée des jeux en 3D ; qui sont plutôt gourmands. Face à cela, Nvidia propose d'ajouter des coeurs supplémentaires dans les circuits de ces machines. Les bénéfices ? Une durée de vie des batteries allongée, et l'e...

  • If you want to make money with apps, go BlackBerry

    An interesting study caught my eye. When taken at face value, it provesthat in order to really make money with apps you have to switch to the BlackBerryplatform.A company I never heard of, MPlayit (its URLcuriously opens a Facebook page), is apparently creating an “app discovery app” on Facebookand polled its users about how much they’re willing to spend on apps.Note immediately that this poll represents only the top of the market: the participants are people that areso interested in apps that they’re...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • How to Point sprite's direction towards Mouse or an Object [duplicate]

    - by Irfan Dahir
    This question already has an answer here: Rotating To Face a Point 1 answer I need some help with rotating sprites towards the mouse. I'm currently using the library allegro 5.XX. The rotation of the sprite works but it's constantly inaccurate. It's always a few angles off from the mouse to the left. Can anyone please help me with this? Thank you. P.S I got help with the rotating function from here: http://www.gamefromscratch.com/post/2012/11/18/GameDev-math-recipes-Rotating-to-face-a-point.aspx Although it's by javascript, the maths function is the same. And also, by placing: if(angle < 0) { angle = 360 - (-angle); } doesn't fix it. The Code: #include <allegro5\allegro.h> #include <allegro5\allegro_image.h> #include "math.h" int main(void) { int width = 640; int height = 480; bool exit = false; int shipW = 0; int shipH = 0; ALLEGRO_DISPLAY *display = NULL; ALLEGRO_EVENT_QUEUE *event_queue = NULL; ALLEGRO_BITMAP *ship = NULL; if(!al_init()) return -1; display = al_create_display(width, height); if(!display) return -1; al_install_keyboard(); al_install_mouse(); al_init_image_addon(); al_set_new_bitmap_flags(ALLEGRO_MIN_LINEAR | ALLEGRO_MAG_LINEAR); //smoother rotate ship = al_load_bitmap("ship.bmp"); shipH = al_get_bitmap_height(ship); shipW = al_get_bitmap_width(ship); int shipx = width/2 - shipW/2; int shipy = height/2 - shipH/2; int mx = width/2; int my = height/2; al_set_mouse_xy(display, mx, my); event_queue = al_create_event_queue(); al_register_event_source(event_queue, al_get_mouse_event_source()); al_register_event_source(event_queue, al_get_keyboard_event_source()); //al_hide_mouse_cursor(display); float angle; while(!exit) { ALLEGRO_EVENT ev; al_wait_for_event(event_queue, &ev); if(ev.type == ALLEGRO_EVENT_KEY_UP) { switch(ev.keyboard.keycode) { case ALLEGRO_KEY_ESCAPE: exit = true; break; /*case ALLEGRO_KEY_LEFT: degree -= 10; break; case ALLEGRO_KEY_RIGHT: degree += 10; break;*/ case ALLEGRO_KEY_W: shipy -=10; break; case ALLEGRO_KEY_S: shipy +=10; break; case ALLEGRO_KEY_A: shipx -=10; break; case ALLEGRO_KEY_D: shipx += 10; break; } }else if(ev.type == ALLEGRO_EVENT_MOUSE_AXES) { mx = ev.mouse.x; my = ev.mouse.y; angle = atan2(my - shipy, mx - shipx); } // al_draw_bitmap(ship,shipx, shipy, 0); //al_draw_rotated_bitmap(ship, shipW/2, shipH/2, shipx, shipy, degree * 3.142/180,0); al_draw_rotated_bitmap(ship, shipW/2, shipH/2, shipx, shipy,angle, 0); //I directly placed the angle because the allegro library calculates radians, and if i multiplied it by 180/3. 142 the rotation would go hawire, not would, it actually did. al_flip_display(); al_clear_to_color(al_map_rgb(0,0,0)); } al_destroy_bitmap(ship); al_destroy_event_queue(event_queue); al_destroy_display(display); return 0; } EDIT: This was marked duplicate by a moderator. I'd like to say that this isn't the same as that. I'm a total beginner at game programming, I had a view at that other topic and I had difficulty understanding it. Please understand this, thank you. :/ Also, while I was making a print of what the angle is I got this... Here is a screenshot:http://img34.imageshack.us/img34/7396/fzuq.jpg Which is weird because aren't angles supposed to be 360 degrees only?

  • Le nouvel Hotmail pourra-t-il concurrencer Gmail ? Découvrez ses nouvelles fonctionnalités en détail

    Mise à jour du 19.05.2010 par Katleen Le nouvel Hotmail pourra-t-il concurrencer Gmail ? Découvrez ses nouvelles fonctionnalités en détails En matière de client mail, Microsoft est très en retard et part avec un gros handicap. Même si son service est celui qui compte le plus d'abonnés (majoritairement à cause de l'utilisation de Messenger), c'est aussi celui dont les utilisateurs sont le moins satisfait, face à un Gmail fonctionnel et sur, par exemple. La firme de Redmond a donc décidé de sortir l'artillerie lourde en remodelant totalement sa messagerie Hotmail. L'accent sera mis sur la sécurité, qui jusqu'ici laissait à désirer. Il sera désormais possible de s'authentifier grâce à des...

  • The Challenges of Corporate Financial Reporting

    - by Di Seghposs
    Many finance professionals face serious challenges in managing and reporting their company’s financial data, despite recent investments in financial reporting systems. Oracle and Accenture launched this research report to help finance professionals better understand the state of corporate financial reporting today, and why recent investments may have fallen short. The study reveals a key central issue: Organizations have been taking a piecemeal—rather than holistic—approach to investing. Without a vision and strategy that addresses process improvement, data integrity, and user adoption software, investments alone will not meet the needs or expectations of most organizations. The research found that the majority of finance teams in 12 countries—including the U.K., USA, France, Germany, Russia, and Spain—have made substantial investments in corporate financial management processes and systems over the last three years. However, many of these solutions, which were expected to improve close, reporting, and filing processes, are ineffective, resulting in a lack of visibility, quality, and confidence in financial data.

  • Application for taking pretty screenshots (like OS X does)

    - by Oli
    I've been building a website for a guy who uses Mac OS X and occasionally he sends me screenshots of bugs. They come out looking like this: This is fairly typical of Mac screenshots. You get the window decorations, the shadow from the window and a white or transparent background (not the desktop wallpaper -- I've checked). Compare this to an Ubuntu window-shot (Alt+Print screen): It's impossible to keep a straight face and say the Ubuntu one anywhere near as elegant. My question is: Is there an application that can do this in Ubuntu? Edit: Follow up: Is there an application that can do this in one move? Shutter is pretty good but running the plugin for every screenshot is pretty tiresome as it doesn't seem to remember my preference (I want south-shadow and that requires selecting south, then clicking refresh, then save) and it's more clicks than I'd like. Is there a simple way of telling shutter I want south-shadow for all screenshots (except entire desktop and area-selection)?

  • C++ vainqueur d'un benchmark avec Java, Scala et Go présenté aux Scala Days, l'étude portait sur l'implémentation d'un algorithme

    C++ vainqueur d'un benchmark avec Java, Scala et Go Présentée aux Scala Days, l'étude portait sur l'implémentation d'un algorithme Bonne nouvelle pour tous les amateurs de C++ ! Ce langage reste le plus performant et sans conteste ! Présenté au Scala Days en début de mois, un benchmark met en compétition le C++, Java, Scala et GO pour l'implémentation du même algorithme en cherchant à s'appuyer sur les éléments du langage (pas de Boost ici donc). Et C++ remporte haut la main en temps d'exécution mais aussi en empreinte mémoire. Mieux, contrairement à certaines idées reçues, les temps de compilation ou le nombre de ligne de code restent à des valeurs qui n'ont pas à rougir face à Java par exemple....

  • Faut-il bannir les boucles "for" du C++ au profit des algorithmes de la bibliothèque standard ?

    La boucle for face aux algorithmes de la bibliothèque standard J'ai donné un jour un exercice à l'un de mes stagiaires : modifier tout le code d'un projet qu'il avait écrit pour remplacer toutes les boucles for par des algorithmes de la bibliothèque standard. Au-delà de ma simple tendance naturelle à torturer les stagiaires, je trouvais cet exercice intéressant pour plusieurs raisons. La première est pédagogique, pour habituer mon stagiaire à apprendre et à utiliser les outils existants de la bibliothèque standard plutôt que repartir systématiquement de zéro. La seconde raison est une question d'expressivité. Lorsque l'on rencontre un for dans le code, on ne peut pas savoir que va faire ce code. Il est nécessaire de l...

  • Calculating angle between 2 vectors

    - by Error 454
    I am working on some movement AI where there are no obstacles and movement is restricted to the XY plane. I am calculating 2 vectors: v - the direction of ship 1 w - the vector pointing from the position of ship 1 to ship 2 I am then calculating the angle between these two vectors using the standard formula: arccos( v . w / ( |v| |w| ) ) The problem I'm having is the nature of arccos only returning values between 0 and 180. This makes it impossible to determine whether I should turn left or right to face the other ship. Is there a better way to do this?

  • Drawing application on OpenGL for iOS (iPad)

    - by Alesia
    Some help is needed. I'm developing drawing application on OpenGL (deployment target 4.0) for iOS (iPad). We have 3 drawing tools: pen, marker (with alfa) and eraser. I draw with textures, using blending in orthographic projection. I can't use z-ordering because in this case I have to face a lot of troubles with cutting and erasing. The thing that I need is to make the pen be always on the top. When I first use marker and than pen - it's ok. But if I use pen first and marker over the pen - I can't see pen color under marker. I'd appreciate any help or advice. Thank you veeeeeery much!

  • Azure Florida Association: Modern Architecture for Elastic Azure Applications

    - by Herve Roggero
    Join us on November 28th at 7PM, US Eastern Time, to hear Zachary Gramana talk about elastic scale on Windows Azure. REGISTER HERE: https://www3.gotomeeting.com/register/657038102 Description: Building horizontally scalable applications can be challenging. If you face the need to rapidly scale or adjust to high load variations, then you are left with little choice. Azure provides a fantastic platform for building elastic applications. Combined with recent advances in browser capabilities, some older architectural patterns have become relevant again. We will dust off one of them, the client-server architecture, and show how we can use its modern incarnation to bypass a class of problems normally encountered with distributed ASP.NET applications.

  • Android 2.3 devrait changer d'UI, Gingerbread répondrait ainsi aux critiques des partenaires de Goog

    Android 2.3 devrait complètement changer d'UI « Gingerbread » répondrait ainsi aux critiques des partenaires de Google sur son interface utilisateur L'interface utilisateur d'Android est-elle « moche » ? Tout est question de goûts et de couleurs, bien sûr, mais il semblerait que des critiques commencent à faire réfléchir Google. Ces critiques émanent principalement des partenaires de Google, les constructeurs de smartphones (HTC et Motorola en tête). Comme Android est un OS open-source, les fabriquants sont libres de le modifier, et donc de changer l'UI, ce qu'ils ne se privent pas faire.

  • DOMDocument programming: a lot of little dilemmas, how to solve them?

    - by Peter Krauss
    I need elegance and performance: how to decide by the "best implementation" for each DOM algorithm that I face. This simple "DOMNodeList grouper" illustrate many little dilemmas: use iterator_to_array or "populate an array", when not all items need to be copied. use clone operator, cloneNode method or import method? use parentNode::method() or documentElement::method? (see here) first removeChild or first replaceChild, no avoids "side effects"? ... My position, today, is only "do an arbitrary choice and follow it in all implementations" (like a "Convention over configuration" principle)... But, there are another considerations? About performance, there are some article showing benchmarks? PS: this is a generic DOM question, any language (PHP, Javascript, Python, etc.) have the problem.

  • What are some important guidelines when starting a software cooperative?

    - by Roy
    We are a group of people who are about to start a software cooperative, which means all of us (and other future workers) will be the owners of the 'company' rather than having bosses and employees. We do this from ideological reasons but also because we believe this allows many advantages - power of democracy (see SE..) , motivation, creativity, good work relations and atmosphere and more. We do face some questions about how exactly ownership of our products should be split, should we give different percentage for different people which put in a different amount of work hours or brings expert knowledge. We want people to feel they get what they deserve, not more, not less, and we're not sure just splitting it even will give this feeling. What are some good guidelines for solving these questions in a cooperative?

  • Common light map practices

    - by M. Utku ALTINKAYA
    My scene consists of individual meshes. At the moment each mesh has its associated light map texture, I was able to implement the light mapping using these many small textures. 1) Of course, I want to create an atlas, but how do you split atlases to pages, I mean do you group the lm's of objects that are close to each other, and load light maps on the fly if scene is expected to be big. 2) the 3d authoring software provides automatic uv coordinates for each mesh in the scene, but there are empty areas in the texel space, so if I scale the texture polygons the texel density of each face wil not match other meshes, if I create atlas like that there will be varying lm resolution, how do you solve this, just leave it as it is, or ignore resolution ? Actually these questions also applies to other non tiled maps.

  • Telerik OpenAccess ORM and the XML Metadata Source

    We all know that Telerik OpenAccess ORM has a completely new face with the Q1 2010 release so it is about time to start blogging about some of the features and improvements that the new Visual Designer brought along.  Today I will talk about one of the most notable changes in the new version of OpenAccess ORM and that is the XML only mapping. You all know that so far with the previous versions of the product the mapping information was defined by a mix of XML configuration files and CLR attributes. After a lot of customer feedback and thorough thought we decided to make the XML and the attributes as two separate and self-contained sources of metadata information about your model. You can choose one based on your personal preferences. I will start with a brief overview over the new XML mapping definition. Unlike previous versions, where all ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

(you solve it and prepare a desired build) did you face miracle (= sudden, positive surprises?) in your life?? what was your reaction in case you have come through such experience?? (N.B.
