  • Le W3C présente Web cryptography API, une norme pour améliorer la sécurité des applications Web

    Le W3C présente Web cryptography API une norme pour améliorer la sécurité des applications Web La sécurité est un aspect important dans le cycle de développement d'une application.

L'organisme vient de publier un premier brouillon (draft) pour l'API Web cryptography. Le projet a...

  • How can I gain access to a player instance in a Minecraft mod?

    - by Andrew Graber
    I'm creating Minecraft mod with a pickaxe that takes away experience when you break a block. The method for taking away experience from a player is addExperience on EntityPlayer, so I need to get an instance of EntityPlayer for the player using my pickaxe when the pickaxe breaks a block, so that I can remove the appropriate amount of experience. My pickaxe class currently looks like this: public class ExperiencePickaxe extends ItemPickaxe { public ExperiencePickaxe(int ItemID, EnumToolMaterial material){ super(ItemID, material); } public boolean onBlockDestroyed(ItemStack par1ItemStack, World par2World, int par3, int par4, int par5, int par6, EntityLiving par7EntityLiving) { if ((double)Block.blocksList[par3].getBlockHardness(par2World, par4, par5, par6) != 0.0D) { EntityPlayer e = new EntityPlayer(); // create an instance e.addExperience(-1); } return true; } } Obviously, I cannot actually create a new EntityPlayer since it is an abstract class. How can I get access to the player using my pickaxe?

  • Studying computer science - what am I getting myself into?

    - by clankercrusher
    I'm a student considering the possibility of studying computer science. I've picked up programming indie games and websites as a hobby and I really enjoy it. Despite my fairly positive experience, I somehow get the feeling that computer science in the business world will be completely different than do-it-for-fun game making. Since I'm interested in the field and I'd like to study well, I want to prepare myself for the onslaught. (If that’s even possible) What are some of the most important principals I need to know if I decide to study computer science? What will I need to know about computer science that a University probably won't teach me? Is there any way I can get hands on experience before or while I'm at a University? What am I getting myself into? P.S. Is this the right stack exchange site for this type of question?

  • How to move to Java enterprise development after Python and Ruby?

    - by rdasxy
    I used to develop in Django/Python and Rails/Ruby (and before that C/C++ and C#), and I'm now at a job where we do enterprise Java development (Spring, Hibernate, RESTEasy, Maven, etc.) for web applications and web services. Coming from the Convention over Configuration world, what's the best way to get up to speed doing enterprise Java web services development? I know Java (the language) well, and I've written GUIs in Swing and basic JSP before, but nothing of the kind I'm doing now. Are there any recommended tutorials to get up to speed on popular Java enterprise development tutorials?

  • How to transform mesh components?

    - by Lea Hayes
    I am attempting to transform the components of a mesh directly using a 4x4 matrix. This is working for the vertex positions, but it is not working for the normals (and probably not the tangents either). Here is what I have: // Transform vertex positions - Works like a charm! vertices = mesh.vertices; for (int i = 0; i < vertices.Length; ++i) vertices[i] = transform.MultiplyPoint(vertices[i]); // Does not work, lighting is messed up on mesh normals = mesh.normals; for (int i = 0; i < normals.Length; ++i) normals[i] = transform.MultiplyVector(normals[i]); Note: The input matrix converts from local to world space and is needed to combine multiple meshes together.

  • 7-Eleven Improves the Digital Guest Experience With 10-Minute Application Provisioning

    - by MichaelM-Oracle
    By Vishal Mehra - Director, Cloud Computing, Oracle Consulting Making the Cloud Journey Matter There’s much more to cloud computing than cutting costs and closing data centers. In fact, cloud computing is fast becoming the engine for innovation and productivity in the digital age. Oracle Consulting Services contributes to our customers’ cloud journey by accelerating application provisioning and rapidly deploying enterprise solutions. By blending flexibility with standardization, our Middleware as a Service (MWaaS) offering is ensuring the success of many cloud initiatives. 10-Minute Application Provisioning Times at 7-Eleven As a case in point, 7-Eleven recently highlighted the scope, scale, and results of a cloud-powered environment. The world’s largest convenience store chain is rolling out a Digital Guest Experience (DGE) program across 8,500 stores in the U.S. and Canada. Everyday, 7-Eleven connects with tens of millions of customers through point-of-sale terminals, web sites, and mobile apps. Promoting customer loyalty, targeting promotions, downloading digital coupons, and accepting digital payments are all part of the roadmap for a comprehensive and rewarding customer experience. And what about the time required for deploying successive versions of this mission-critical solution? Ron Clanton, 7-Eleven's DGE Program Manager, Information Technology reported at Oracle Open World, " We are now able to provision new environments in less than 10 minutes. This includes the complete SOA Suite on Exalogic, and Enterprise Manager managing both the SOA Suite, Exalogic, and our Exadata databases ." OCS understands the complex nature of innovative solutions and has processes and expertise to help clients like 7-Eleven rapidly develop technology that enhances the customer experience with little more than the click of a button. OCS understood that the 7-Eleven roadmap required careful planning, agile development, and a cloud-capable environment to move fast and perform at enterprise scale. Business Agility Today’s business-savvy technology leaders face competing priorities as they confront the digital disruptions of the mobile revolution and next-generation enterprise applications. To support an innovation agenda, IT is required to balance competing priorities between development and operations groups. Standardization and consolidation of computing resources are the keys to success. With our operational and technical expertise promoting business agility, Oracle Consulting's deep Middleware as a Service experience can make a significant difference to our clients by empowering enterprise IT organizations with the computing environment they seek to keep up with the pace of change that digitally driven business units expect. Depending on the needs of the organization, this environment runs within a private, public, or hybrid cloud infrastructure. Through on-demand access to a shared pool of configurable computing resources, IT delivers the standard tools and methods for developing, integrating, deploying, and scaling next-generation applications. Gold profiles of predefined configurations eliminate the version mismatches among databases, application servers, and SOA suite components, delivered both by Oracle and other enterprise ISVs. These computing resources are well defined in business terms, enabling users to select what they need from a service catalog. Striking the Balance between Development and Operations As a result, development groups have the flexibility to choose among a menu of available services with descriptions of standard business functions, service level guarantees, and costs. Faced with the consumerization of enterprise IT, they can deliver the innovative customer experiences that seamlessly integrate with underlying enterprise applications and services. This cloud-powered development and testing environment accelerates release cycles to ensure agile development and rapid deployments. At the same time, the operations group is relying on certified stacks and frameworks, tuned to predefined environments and patterns. Operators can maintain a high level of security, and continue best practices for applications/systems monitoring and management. Moreover, faced with the challenges of delivering on service level agreements (SLAs) with the business units, operators can ensure performance, scalability, and reliability of the infrastructure. The elasticity of a cloud-computing environment – the ability to rapidly add virtual machines and storage in response to computing demands -- makes a difference for hardware utilization and efficiency. Contending with Continuous Change What does it take to succeed on the promise of the cloud? As the engine for innovation and productivity in the digital age, IT must face not only the technical transformations but also the organizational challenges of the cloud. Standardizing key technologies, resources, and services through cloud computing is only one part of the cloud journey. Managing relationships among multiple department and projects over time – developing the management, governance, and monitoring capabilities within IT – is an often unmentioned but all too important second part. In fact, IT must have the organizational agility to contend with continuous change. This is where a skilled consulting services partner can play a pivotal role as a trusted advisor in the successful adoption of cloud solutions. With a lifecycle services approach to delivering innovative business solutions, Oracle Consulting Services has expertise and a portfolio of services to help enterprise customers succeed on their cloud journeys as well as other converging mega trends .

  • Why should I adopt MVC?

    - by Andrew
    I decided to get my hands wet and got the YII framework for PHP. I created my first application, then created new controller, model and view. Connected to database, got my record passed from controller to the view and printed the hello world. I am confused now. If I have to do the same thing for each page, this seems like a nightmare to me. In each controller I have to do a lot of same operations - declare variables, and pass them to views. I also need to create models for each page and this is all confusing to me. In my idea the main goal of development is to avoid duplication, but what I see here is lots and lots of duplicated code. Please advise and clarify. Maybe you could suggest a good reading about MVC and coding patterns and best practices in MVC. Because so far, it takes much more time to create a small site using MVC than using my own programming schema.

  • In launcher, disable the music suggestion section

    - by Nicolas Raoul
    Everytime I want to launch an office program, I begin typing "of" in the launcher, and... pictures of lightly-clothed ladies show up. Not the end of the world, but because I do this a lot in front of customers and bosses, it is often embarrassing. I have already disabled Zeitgeist and "recently used". Banshee does not have any Zeitgeist item in Edit > Preferences > Extensions. Is there a way to disable this "Music" section in the launcher suggestions? Or maybe I just must stop playing dance music via Banshee...

  • Keeping rotation between two objects

    - by user99
    In my XNA game I have two objects that collide. When the first object collides with the other it is able to latch on to it and move it about the world. I am having a problem with the math here (Math isn't my strong point). I currently have the second object latch on to the first and move around with it, but I cannot get it to keep it's original direction. So, if the object is facing up it should keep this direction relative to how it is being rotated with the original item. Any tips on how I could best to achieve this?

  • Advice for transitioning into a Java developer position from doing other types of web development?

    - by Rick
    I've been doing web programming and currently work at a company working with mainly PHP and Javascript. For a little while now I've been becoming more and more frustrated with the shortcomings of this type of development and want to move to a company with a more defined development process that values doing things the "right way" such as using Unit tests, dependency injection / IoC, etc. I've been learning JEE / Java as much as I can on my own time but would really like to make a switch to doing this as my career and leave behind the PHP world altogether. I'm just wondering if anyone can give me advice on which things to put my main focus on right now to make myself marketable as an entry level Java developer. Basically, I feel that I'm not really learning anything new at my current job that will benefit me and its only making me more and more frustrated so I figure if there is any way to position myself for a transition I would rather do it sooner than later. Thanks for any advice.

  • New Solaris 11 Customer Maintenance Lifecycle blog

    - by user12244672
    Hi Folks, On the basis that you can't have too much of a good thing, I've started a 2nd blog, the Solaris11Life blog , to enable me to blog about all aspects of the Solaris 11 Customer Maintenance Lifecycle, including policies, best practices, resource links, clarifications, and anything else which I hope you may find useful. In my first post, I share my Solaris 11 Customer Maintenance Lifecycle presentation, which I gave at Oracle Open World and the recent Deutsche Oracle Anwendergruppe (DOAG) conference. I'll be posting lots more there in the coming week as time allows, including secret handshake stuff on how to interpret IPS FMRI version strings. In future, I'll post any Solaris 11 Customer Maintenance Lifecycle related material on the Solaris11Life blog, http://blogs.oracle.com/Solaris11Life , and any Solaris 10 or below material here on the Patch Corner blog, http://blogs.oracle.com/patch . Best Wishes, Gerry.

  • More free geek-read.December SolidQ Journal is online

    - by Greg Low
    I'm really excited to see the last SolidQ Journal for this year out the door. It's our free online magazine. I've been wondering about the future of printed technical magazines for a long time. I doubt they have much of a future, as online publications become more prevalent and more timely. By the time a print magazine gets to you, it's such a long time since the author wrote the material that it's hard to even retain relevance in a fast moving world. That's why I'm so happy to have the format we...(read more)

  • Check for bodies within a specific circle in Box2D

    - by ltjax
    I'm trying to find positions to insert new bodies into my world. For that, I'd like to have a "free" spot where this body wouldn't overlap with anything else. So my plan was to sample "random" positions and check whether they overlap with my "potential" new body. Since my bodies are always circular, I'd need to test within a given circle. So far, the only way to use box2d for this seems to use b2World::QueryAABB around my circle and manually doing an overlap test with all the fixtures it gives me (Box2D doesn't event seem to allow me to tap into its overlapping tests?!). It seems to me like Box2D should already provide such functionality - is there a way that lets me do this without reinventing most of the wheel again?

  • Balancing agressive invites

    - by Nils Munch
    I am designing a trading card game for mobiles, with the possibility to add cards to your collection using Gems, aquired through victories and inapp purchases. I am thinking to increase the spread of the game with a tracking system on game invites, enabling the user to invite a friend to play the game. If the friend doesn't own the game client (which is free) he will be offered to download it. If he joins the game, the original player earns X amount of gems as an reward. There can only be one player per mobile device, which should rule out some harvesting. My question is, how do you think the structure of this would be recieved ? All invites are mail based, unless the player already exists in the game world (then he gets a ingame invitation.) I have set a flood filter, so a player can only invite a friend (without the client installed) once a month.

    Curious what the future will look like? According to movie directors, casting their lens towards the future of humanity, it’s quite a mixed bag. Check out this infographic timeline to check out the next 300,000 years of human evolution. A quick glance over the timeline shows a series of future where things can quickly go from the fun times to the end-of-the-world times. We’d like to, for example, live it up in the Futurama future of 3000 AD and not the Earth-gets-destroyed future of Titan A.E’s 3028. Hit up the link below for a high-res copy of the infographic.

  • Why is chunk size often a power of two?

    - by danijar
    There are many Minecraft clones out there and I am working on my own implementation. A principle of terrain rendering is tiling the whole world in fixed size chunks to reduce the effort of localized changes. In Minecraft the chunk size is 16 x 16 x 256 as far as I now. And in clones I also always saw chunk sizes of a power of the number 2. Is there any reason for that, maybe performance or memory related? I know that powers of 2 play a special role in binary computers but what has that to do with the chunk size?

  • Why didn't IE8 support border-radius, evil or ignorance?

    - by Mark Rogers
    When I think back to the time of the release of IE7, I was surprised that there wasn't border-radius support. It seems like an obviously great idea to have a css-property name for rounded corners, which can potentially make a site look less like it came from the computer stone-age. Finally, today we have IE9 and Microsoft finally decided to play ball with the rest of the world. But the question remains, why didn't Microsoft bother to support border-radius in IE8? The problem probably became obvious to the company as the growing chorus of complaints from web developers got louder after the release of IE7. Was the company so isolated or in group-think mode that they were blind for that many years? Or did Microsoft have some additional motive to suppress the border-radius property?
