  • Support for non-english characters?

    - by TomJ
    Is support for non-english characters common in programming languages? I mean, technically, I would think it is feasable, but I don't have any experience in anything other than english, so I don't know how common it is. I know that there are non-english based programming languages, but can something like C#, C++, C, Java, or Python support non-english classes/methods/variables? Example in go (url, http://play.golang.org/p/wRYCNVdbjC) package main import "fmt" type ?? struct { ?? string } func main() { fmt.Println("Hello, ??") ?? := new(??) ??.?? = "hello world" fmt.Println(??.??) }

  • How does a BSP tree work for Z sorting?

    - by Jenko
    I'm developing a 3D engine in software, and so I must compute Z sorting manually. I'm currently using the painters algorithm to sort triangles and then drawing them back-to-front. This causes artifacts that I'm trying to correct. Would using a dynamic BSP-tree ensure "correct Z sorting" of triangles? Why? Because the bounding volumes of triangles would be similar? Since I would have a single "world" BSP tree, would I have to remove and re-add any moved/scaled/rotated object into the tree? Is it possible to add triangles into a BSP tree without the expensive cutting process? Why do you need to cut triangles on the axis planes anyway? Is it faster to traverse a BSP tree from any angle, than to sort all tris each draw like the painters algorithm?

  • How can I enable auto-switching HDMI sound on Ubuntu 12.04?

    - by João Ciocca
    I've just installed Ubuntu 12.04 on my Lenovo G550 notebook and decided to test the main thing I use it for, on Windows: watching movies and series on my living room TV. Plugged in the HDMI cable, screen auto-configured nicely - awesome. But the sound is coming through my notebook's speakers, instead of my TV. Searched for almost an hour on Google, found a couple of things - nothing that helped, though. Here are two links that made me sad: Another question on AskUbuntu "a better sounding world" post about HDMI On 2, David says that autoswitching was disabled... so how can I enable it?

  • 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.

  • Oracle Usability Advisory Board, Europe

    - by ultan o'broin
    Earlier this month, I attended the first Oracle Usability Advisory Board meeting in Europe (held in Oracle's big campus in Thames Valley Park, Reading, in the UK). My main interest here of of course was to listen to customer's experiences and requirements in the area of user experience, focusing in on user assistance natch, but also, given my background in the translation and internationalization world, to watch out for issues in those areas that impact on the UX. I met some great people there and took away some powerful UX thoughts about where might go with the area of language in the UI, localizations, and other cultural issues. One area of special interest to me is language as part of the user experience. By language I mean terminology and style of wordings you see in interfaces and help. Are they reflective of how people really work and are used to. What is its relationship to competitiveness and productivity. An area rich in research potential for UX. Debra Lilley Fujitsu (Oracle partner), who also attended, has some good coverage of the event here. On to the next one!

  • 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?

  • 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.

  • Determine corners of a specific plane in the frustum

    - by Takumi
    I'm working on a game with a 2D view in a 3D world. It's a kind of shoot'em up. I've a spaceship at the center of the screen and i want that ennemies appear at the borders of my window. Now i don't know how to determine positions of the borders of the window. For example, my camera is at (0,0,0) and looking forward (0,0,1). I set my spaceship at (0,0,50). I also know the near plane (1) and the far plane(1000). I think i'd have to find the 4 corners of the plane in the frustum whose z position is 50, and with these corner i can determine borders. But i don't know how to determine x and y.

  • Is it common to prototype in a higher level language?

    - by Mark Canlas
    I'm currently toying with the idea of embarking on a project that far exceeds my current programming ability in a language I have very little real world experience in (C). Would it be valuable to prototype in a higher level language that I'm more familiar with (like Perl/Python/Ruby/C#) just so I can get the overall design going? Ultimately, the final product is performance sensitive, hence the choice of C, but I'm afraid not knowing C well will make me lose the forest for the trees. While searching for similar questions, I noticed one fellow mention that programmers used to prototype in Prolog, then crank it out in assembler.

  • Where can I find a good Hibernate Criteria tutorial that doesn't use cats and kittens? [closed]

    - by cbmeeks
    I've been using Hibernate a little while (HQL) and want to try Criteria's for a few scenarios we have here. I'm trying to get a few inner joins (2 layers deep) and am struggling a little. I go to the official site and they teach by cats and kittens. I don't care about cats and kittens and find the analogy hard to follow. Orders, details, shipments, etc. Nice, boring business references is what I enjoy. I tried to Google it but all I get are early 2000's websites with so many flashing GIF's, cluttered displays, flash overs and "tummy tuck" ads I want to puke. Why can't the java world have sites like http://guides.rubyonrails.org/? And no, I'm not advocating I volunteer to create a similar site. :-) Anyway, any good site that can give a nice tutorial on Criteria based searches would be appreciated.

  • New insights I can learn from the Groovy language

    - by Andrea
    I realize that, for a programmer coming from the Java world, Groovy contains a lot of new ideas and cool tricks. My situation is different, as I am learning Groovy coming from a dynamic background, mainly Python and Javascript. When learning a new language, I find that it helps me if I know beforehand which features are more or less old acquaintances under a new syntax and which ones are really new, so that I can concentrate on the latter. So I would like to know which traits distinguish Groovy among the dynamic languages. What are the ideas and insights that a programmer well-versed in dynamic languages should pay attention to when learning Groovy?

  • 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.

  • Parleys Testimonial at GlassFish Community Event, JavaOne 2012

    - by arungupta
    Parleys.com is an e-learning platform that provide a unique experience of online and offline viewing presentations, with integrated movies and chaptering, from the top notch developer conferences and about 40 JUGs all around the world. Stephan Janssen (the Devoxx man and Parleys webmaster) presented at the GlassFish Community Event at JavaOne 2012 and shared why they moved from Tomcat to GlassFish. The move paid off as GlassFish was able to handle 2000 concurrent users very easily. Now they are also running Devoxx CFP and registration on this updated infrastructure. The GlassFish clustering, the asadmin CLI, application versioning, and JMS implementation are some of the features that made them a happy user. Recently they migrated their application from Spring to Java EE 6. This allows them to get locked into proprietary frameworks and also avoid 40MB WAR file deployments. Stateless application, JAX-RS, MongoDB, and Elastic Search is their magical forumla for success there. Watch the video below showing him in full action: More details about their infrastructure is available here.

  • 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?

  • 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?

  • How do I hire testers by giving them a buggy app for testing their efficiency?

    - by Jay
    My boss wants to recruit testers based on their testing efficiency (number of bugs identified). So, he's shortlisted 5 people and I need to give them an app full of bugs and see how they fare in reporting obvious bugs, and hidden bugs. I know.... it kind of sounds weird. I guess, this is just like the coding world, where you hire a programmer by assessing his/her programming ability (which is a little easier). Once hired, these testers would be testing a java swing app, so their familiarity of testing frameworks/tools is not really required. So, my question here is - How do I go about finding buggy apps (web/non-web), preferably java ones, that I can have the shortlisted testers have a go at? How would you go about this task if your boss asks you to do so? I am kind of clueless at this point - I googled a bit, thought about finding new apps on sourceforge with lots of bugs, but both approaches didn't work for me.
