For example a moving object will cause only its bounding box to be redrawn instead of the full scene. This background canvas is copied to the main canvas in each iteration.

• We'll be at QCon San Francisco!

  - by Carlos Chang

  Oracle Technology Network is a Platinum sponsor at QCon San Francisco. Don’t miss these great developer focused sessions: Shay Shmeltzer - How we simplified Web, Mobile and Cloud development for our own developers? - the Oracle Story Over the past several years, Oracle has beendeveloping a new set of enterprise applications in what is probably one of the largest Java based development project in the world. How do you take 3000 developers and make them productive? How do you insure the delivery of cutting edge UIs for both Mobile and Web channels? How do you enable Cloud based development and deployment? Come and learn how we did it at Oracle, and see how the same technologies and methodologies can apply to your development efforts. Dan Smith - Project Lambda in Java 8 Java SE 8 will include major enhancements to the Java Programming Language and its core libraries.  This suite of new features, known as Project Lambda in the OpenJDK community, includes lambda expressions, default methods, and parallel collections (and much more!).  The result will be a next-generation Java programming experience with more flexibility and better abstractions.   This talk will introduce the new Java features and offer a behind-the-scenes view of how they evolved and why they work the way that they do. Arun Gupta - JSR 356: Building HTML5 WebSocket Applications in Java The family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform. The complete conference schedule is here: http://qconsf.com/sf2012/schedule/wednesday.jsp But wait, there’s more! At the Oracle booth, we’ll also be covering: Oracle ADF Mobile Oracle Developer Cloud Service Oracle ADF Essentials NetBeans Project Easel Hope to see you there!

• browser without gpu support

  - by manuzhang

  Google has an Easter egg that draws 3D graph but when I tried it out on chrome it complained about no WebGL support. I've also tested it on Firefox whose WebGL support was enabled but ended up with the same problem. Thus, I suspect it's an issue of my GPU. Some googling led me to chrome://gpu and here's what I got Graphics Feature Status Canvas: Software only, hardware acceleration unavailable HTML Rendering: Software only, hardware acceleration unavailable 3D CSS: Unavailable. Hardware acceleration unavailable WebGL: Unavailable. Hardware acceleration unavailable WebGL multisampling: Unavailable. Hardware acceleration unavailable Problems Detected GPU process was unable to boot. Access to GPU disallowed. GL driver is software rendered. Accelerated compositing is disabled.: 59302 Mesa drivers in linux older than 7.11 are assumed to be buggy. Accelerated 2d canvas is unstable in Linux at the moment.

• My Windows 8 App in Windows Store

  - by Stephen.Walther

  Finally, you have a good reason to upgrade to Windows 8! My Brain Eaters app was just accepted into the Windows Store. Just in time for Halloween! The Brain Eaters app is a sample app from my soon to be released book Windows 8 Apps with HTML5 and JavaScript. The game illustrates several important programming concepts which you need when building Windows 8 games with JavaScript such as using HTML5 Canvas and the new requestAnimationFrame() method. If you are looking for Halo or Call of Duty then you will be disappointed. If you are looking for PAC-MAN then you will be disappointed. I created the simplest arcade game that I could imagine so I could explain it in the book. All of the code for the game is included with the book. The goal of the game is to eat the food pellets while avoiding the zombies while running around a maze. Every time you get eaten by a zombie, you can hear my six year old son saying “Oh No!”. Here’s the link to the game: http://apps.microsoft.com/webpdp/app/brain-eaters/e283c8d0-1fed-4b26-a8bf-464584c9de6d

• How do you make slides for programming talks?

  - by Yuvi Masory

  I've given a few talks recently and I have not found a good way to make slides. Here are a few desirable characteristics for programming slides: They're slides. A standard emacs buffer won't do it. They have syntax highlighting for code. They support basic formatting, like font size and color and bullets. No fancy animations needed. The only animation I desire is one-by-one appearance of bullets. So far I have considered: Microsoft Office - out of the question for Linux users. OpenOffice.org - too much for my needs, code formatting/highlighting needs to be done externally and pasted in. On the plus side supports bullets, bullet-by-bullet animation, and font formatting. Emacs - Supports all the code formatting but I haven't found a slides mode that lets me transition from one chunk to another. HTML5 - I once made slides using html5rocks as a template. It supports everything, but is too hard and time-consuming the "throw together" a few slides before a minor talk. Also the html5-only features may not work on the podium computer's installed browser. Any suggestions for programs/techniques for making code-centric presentations?

• At the Java DEMOgrounds - Java EE 7 WebSocket Early Access

  - by Janice J. Heiss

  At the packed and happening Java DEMOgrounds, I wandered over to check out Java EE Web Profile and Platform Technologies. Martin Matula, a Senior Development Manager at Oracle on the JavaEE/GlassFish team, responsible for the area of web services (including JAX-WS and JAX-RS), was demonstrating Java EE Web Profile and Platform Technologies.Matula was previewing some Java EE 7 WebSocket early access features via a group drawing application that showcases the upcoming JSR 356, “Java API for WebSocket”, which is the API for building RESTful web services and Server-Sent Events, an HTML5 feature. He emphasized that this is supported in Jersey, the reference implementation for JAX-RS, as well.“In this demo,” Matula explained, “I have a simple JavaScript front-end talking to the back-end deployed on GlassFish. It uses RESTful web services to get the list of drawings we have. I can create new drawings and the list is updated immediately using the Server-Sent Events, so the message is coming from the server to the client. Everything is getting updated live using WebSocket, which is the bi-directional communication new protocol in HTML5. This is using Project Jersey and Project Tyrus. Tyrus is the implementation of WebSocket protocol for Java. Jersey implements the RESTful APIs as well as the Server-Sent Events protocol.”

• Google Chrome with strange behavior

  - by user72274

  I'm former Chromium-browser user, but after not upgrading the PPA for 2 months, I switched to Google Chrome browser yesterday. Everything is okay, except some strange behavior on some pages and crashing after loading "chrome://" configuration pages. The best known website with strange behavior is youtube, there is a picture what I see: When I open user menu in top right corner, it crashes that way and even after closing the menu, some parts of menu stay display. You may say it's Youtube problem, no, I have this problem at least on three other websites, here it is on Imgur: The problem isn't for the whole side, sometimes it happens from the middle of the screen. The interesting part is that it happens everytime in the same distance from the right border. When I check the DOM elements with the Developer tool, the overlay which shows element's position is rendered how it should be. What is more, if there is anchor after the crashed area, it works after clicking on it. Selecting text in crashed page is impossible. I hope there is enough information to give me an advice, thanks in advance. :) EDIT: Here is what the browser posted in "chrome://gpu-internals/": Graphics Feature Status Canvas: Software only, hardware acceleration unavailable Compositing: Hardware accelerated 3D CSS: Hardware accelerated CSS Animation: Software animated. WebGL: Hardware accelerated WebGL multisampling: Hardware accelerated Problems Detected Accelerated CSS animation has been disabled at the command line. Accelerated 2d canvas is unstable in Linux at the moment. Ubuntu 12.04 | Gnome-shell 3.4.1 | ATI Radeon 4550 | Screen resolution 1024*768 | Chrome version 20.0.1132.57 (Official Build 145807)

• How do I create an efficient long, pannable, sprite-animated scene in a Windows Store game?

  - by Groo

  I am creating my first Windows Store application in XAML, and I cannot seem to find a proper example for the requirements I have. The basic idea of the app is to have a large scrollable canvas which would lazily start animating visible parts of the view as soon as user stops panning over a certain content (with some audio played also): My original idea was to use a StackPanel to add a bunch of custom controls, each of which would then animate itself once visible (with a short delay), but I have a couple of concerns: If the entire canvas is ~50 screen widths wide, is it feasible to load all content at the beginning, or do I need to plan doing some lazy loading during scrolling? For example, when I select a certain region in the Bing Travel app, it seems to lazily load tiles as I scroll it towards the end. Since content is stretched 100% vertically, and these animations are vectorized to be resolution independent, I am not sure if XAML (CompositionTarget) will be able to handle this, or I have to go for DirectX (MonoGame or C++) to get rid of flicker. Even better, is there an example for Windows 8 which uses a 100% vertically sized GridView with custom animated controls inside?

• How to handle class dependency with interfaces and implementatons

  - by lealand

  I'm using ObjectAid with Eclipse to generate UML class diagrams for my latest Java project, and I currently have a handful of situations like this, where I have a dependency between two interfaces, as well as one of the implementations of one of the interfaces. Here, foo is the graphics library I'm using. In the previous example, FooCanvas draws ITexture objects to the screen, and both FooCanvas and its interface, ICanvas, take ITexture objects as arguments to their methods. The method in the canvas classes which cause this dependency is the following: void drawTexture(ITexture texture, float x, float y); Additionally, I tried a variation on the method signature using Java's generics: <T extends ITexture> void drawTexture(T texture, float x, float y); The result of this was a class diagram where the only dependencies where between the interfaces and the implementing classes, and no dependency by a canvas object on a texture. I'm not sure if this is more ideal or not. Is the dependency of both the interface and implementation on another interface an expected pattern, or is it typical and/or possible to keep the implementation 'isolated' from its interfaces dependencies? Or is the generic method the ideal solution?

• SINGLE SIGN ON SECURITY THREAT! FACEBOOK access_token broadcast in the open/clear

  - by MOKANA

  Subsequent to my posting there was a remark made that this was not really a question but I thought I did indeed postulate one. So that there is no ambiquity here is the question with a lead in: Since there is no data sent from Facebook during the Canvas Load process that is not at some point divulged, including the access_token, session and other data that could uniquely identify a user, does any one see any other way other than adding one more layer, i.e., a password, sent over the wire via HTTPS along with the access_toekn, that will insure unique untampered with security by the user? Using Wireshark I captured the local broadcast while loading my Canvas Application page. I was hugely surprised to see the access_token broadcast in the open, viewable for any one to see. This access_token is appended to any https call to the Facebook OpenGraph API. Using facebook as a single click log on has now raised huge concerns for me. It is stored in a session object in memory and the cookie is cleared upon app termination and after reviewing the FB.Init calls I saw a lot of HTTPS calls so I assumed the access_token was always encrypted. But last night I saw in the status bar a call from what was simply an http call that included the App ID so I felt I should sniff the Application Canvas load sequence. Today I did sniff the broadcast and in the attached image you can see that there are http calls with the access_token being broadcast in the open and clear for anyone to gain access to. Am I missing something, is what I am seeing and my interpretation really correct. If any one can sniff and get the access_token they can theorically make calls to the Graph API via https, even though the call back would still need to be the site established in Facebook's application set up. But what is truly a security threat is anyone using the access_token for access to their own site. I do not see the value of a single sign on via Facebook if the only thing that was established as secure was the access_token - becuase for what I can see it clearly is not secure. Access tokens that never have an expire date do not change. Access_tokens are different for every user, to access to another site could be held tight to just a single user, but compromising even a single user's data is unacceptable. http://www.creatingstory.com/images/InTheOpen.png Went back and did more research on this: FINDINGS: Went back an re ran the canvas application to verify that it was not any of my code that was not broadcasting. In this call: HTTP GET /connect.php/en_US/js/CacheData HTTP/1.1 The USER ID is clearly visible in the cookie. So USER_ID's are fully visible, but they are already. Anyone can go to pretty much any ones page and hover over the image and see the USER ID. So no big threat. APP_ID are also easily obtainable - but . . . http://www.creatingstory.com/images/InTheOpen2.png The above file clearly shows the FULL ACCESS TOKEN clearly in the OPEN via a Facebook initiated call. Am I wrong. TELL ME I AM WRONG because I want to be wrong about this. I have since reset my app secret so I am showing the real sniff of the Canvas Page being loaded. Additional data 02/20/2011: @ifaour - I appreciate the time you took to compile your response. I am pretty familiar with the OAuth process and have a pretty solid understanding of the signed_request unpacking and utilization of the access_token. I perform a substantial amount of my processing on the server and my Facebook server side flows are all complete and function without any flaw that I know of. The application secret is secure and never passed to the front end application and is also changed regularly. I am being as fanatical about security as I can be, knowing there is so much I don’t know that could come back and bite me. Two huge access_token issues: The issues concern the possible utilization of the access_token from the USER AGENT (browser). During the FB.INIT() process of the Facebook JavaScript SDK, a cookie is created as well as an object in memory called a session object. This object, along with the cookie contain the access_token, session, a secret, and uid and status of the connection. The session object is structured such that is supports both the new OAuth and the legacy flows. With OAuth, the access_token and status are pretty much al that is used in the session object. The first issue is that the access_token is used to make HTTPS calls to the GRAPH API. If you had the access_token, you could do this from any browser: https://graph.facebook.com/220439?access_token=... and it will return a ton of information about the user. So any one with the access token can gain access to a Facebook account. You can also make additional calls to any info the user has granted access to the application tied to the access_token. At first I thought that a call into the GRAPH had to have a Callback to the URL established in the App Setup, but I tested it as mentioned below and it will return info back right into the browser. Adding that callback feature would be a good idea I think, tightens things up a bit. The second issue is utilization of some unique private secured data that identifies the user to the third party data base, i.e., like in my case, I would use a single sign on to populate user information into my database using this unique secured data item (i.e., access_token which contains the APP ID, the USER ID, and a hashed with secret sequence). None of this is a problem on the server side. You get a signed_request, you unpack it with secret, make HTTPS calls, get HTTPS responses back. When a user has information entered via the USER AGENT(browser) that must be stored via a POST, this unique secured data element would be sent via HTTPS such that they are validated prior to data base insertion. However, If there is NO secured piece of unique data that is supplied via the single sign on process, then there is no way to guarantee unauthorized access. The access_token is the one piece of data that is utilized by Facebook to make the HTTPS calls into the GRAPH API. it is considered unique in regards to BOTH the USER and the APPLICATION and is initially secure via the signed_request packaging. If however, it is subsequently transmitted in the clear and if I can sniff the wire and obtain the access_token, then I can pretend to be the application and gain the information they have authorized the application to see. I tried the above example from a Safari and IE browser and it returned all of my information to me in the browser. In conclusion, the access_token is part of the signed_request and that is how the application initially obtains it. After OAuth authentication and authorization, i.e., the USER has logged into Facebook and then runs your app, the access_token is stored as mentioned above and I have sniffed it such that I see it stored in a Cookie that is transmitted over the wire, resulting in there being NO UNIQUE SECURED IDENTIFIABLE piece of information that can be used to support interaction with the database, or in other words, unless there were one more piece of secure data sent along with the access_token to my database, i.e., a password, I would not be able to discern if it is a legitimate call. Luckily I utilized secure AJAX via POST and the call has to come from the same domain, but I am sure there is a way to hijack that. I am totally open to any ideas on this topic on how to uniquely identify my USERS other than adding another layer (password) via this single sign on process or if someone would just share with me that I read and analyzed my data incorrectly and that the access_token is always secure over the wire. Mahalo nui loa in advance.

• WebGL First Person Camera - Matrix issues

  - by Ryan Welsh

  I have been trying to make a WebGL FPS camera.I have all the inputs working correctly (I think) but when it comes to applying the position and rotation data to the view matrix I am a little lost. The results can be viewed here http://thistlestaffing.net/masters/camera/index.html and the code here var camera = { yaw: 0.0, pitch: 0.0, moveVelocity: 1.0, position: [0.0, 0.0, -70.0] }; var viewMatrix = mat4.create(); var rotSpeed = 0.1; camera.init = function(canvas){ var ratio = canvas.clientWidth / canvas.clientHeight; var left = -1; var right = 1; var bottom = -1.0; var top = 1.0; var near = 1.0; var far = 1000.0; mat4.frustum(projectionMatrix, left, right, bottom, top, near, far); viewMatrix = mat4.create(); mat4.rotateY(viewMatrix, viewMatrix, camera.yaw); mat4.rotateX(viewMatrix, viewMatrix, camera.pitch); mat4.translate(viewMatrix, viewMatrix, camera.position); } camera.update = function(){ viewMatrix = mat4.create(); mat4.rotateY(viewMatrix, viewMatrix, camera.yaw); mat4.rotateX(viewMatrix, viewMatrix, camera.pitch); mat4.translate(viewMatrix, viewMatrix, camera.position); } //prevent camera pitch from going above 90 and reset yaw when it goes over 360 camera.lockCamera = function(){ if(camera.pitch > 90.0){ camera.pitch = 90; } if(camera.pitch < -90){ camera.pitch = -90; } if(camera.yaw <0.0){ camera.yaw = camera.yaw + 360; } if(camera.yaw >360.0){ camera.yaw = camera.yaw - 0.0; } } camera.translateCamera = function(distance, direction){ //calculate where we are looking at in radians and add the direction we want to go in ie WASD keys var radian = glMatrix.toRadian(camera.yaw + direction); //console.log(camera.position[3], radian, distance, direction); //calc X coord camera.position[0] = camera.position[0] - Math.sin(radian) * distance; //calc Z coord camera.position[2] = camera.position [2] - Math.cos(radian) * distance; console.log(camera.position [2] - (Math.cos(radian) * distance)); } camera.rotateUp = function(distance, direction){ var radian = glMatrix.toRadian(camera.pitch + direction); //calc Y coord camera.position[1] = camera.position[1] + Math.sin(radian) * distance; } camera.moveForward = function(){ if(camera.pitch!=90 && camera.pitch!=-90){ camera.translateCamera(-camera.moveVelocity, 0.0); } camera.rotateUp(camera.moveVelocity, 0.0); } camera.moveBack = function(){ if(camera.pitch!=90 && camera.pitch!=-90){ camera.translateCamera(-camera.moveVelocity, 180.0); } camera.rotateUp(camera.moveVelocity, 180.0); } camera.moveLeft = function(){ camera.translateCamera(-camera.moveVelocity, 270.0); } camera.moveRight = function(){ camera.translateCamera(-camera.moveVelocity, 90.0); } camera.lookUp = function(){ camera.pitch = camera.pitch + rotSpeed; camera.lockCamera(); } camera.lookDown = function(){ camera.pitch = camera.pitch - rotSpeed; camera.lockCamera(); } camera.lookLeft = function(){ camera.yaw= camera.yaw - rotSpeed; camera.lockCamera(); } camera.lookRight = function(){ camera.yaw = camera.yaw + rotSpeed; camera.lockCamera(); } . If there is no problem with my camera then I am doing some matrix calculations within my draw function where a problem might be. //position cube 1 worldMatrix = mat4.create(); mvMatrix = mat4.create(); mat4.translate(worldMatrix, worldMatrix, [-20.0, 0.0, -30.0]); mat4.multiply(mvMatrix, worldMatrix, viewMatrix); setShaderMatrix(); gl.bindBuffer(gl.ARRAY_BUFFER, vertexBuffer); gl.vertexAttribPointer(shaderProgram.attPosition, 3, gl.FLOAT, false, 8*4,0); gl.vertexAttribPointer(shaderProgram.attTexCoord, 2, gl.FLOAT, false, 8*4, 3*4); gl.vertexAttribPointer(shaderProgram.attNormal, 3, gl.FLOAT, false, 8*4, 5*4); gl.activeTexture(gl.TEXTURE0); gl.bindTexture(gl.TEXTURE_2D, myTexture); gl.uniform1i(shaderProgram.uniSampler, 0); gl.useProgram(shaderProgram); gl.drawArrays(gl.TRIANGLES, 0, vertexBuffer.numItems); //position cube 2 worldMatrix = mat4.create(); mvMatrix = mat4.create(); mat4.multiply(mvMatrix, worldMatrix, viewMatrix); mat4.translate(worldMatrix, worldMatrix, [40.0, 0.0, -30.0]); setShaderMatrix(); gl.drawArrays(gl.TRIANGLES, 0, vertexBuffer.numItems); //position cube 3 worldMatrix = mat4.create(); mvMatrix = mat4.create(); mat4.multiply(mvMatrix, worldMatrix, viewMatrix); mat4.translate(worldMatrix, worldMatrix, [20.0, 0.0, -100.0]); setShaderMatrix(); gl.drawArrays(gl.TRIANGLES, 0, vertexBuffer.numItems); camera.update();

• Java2Days 2012 Trip Report

  - by reza_rahman

  Java2Days 2012 was held in beautiful Sofia, Bulgaria on October 25-26. For those of you not familiar with it, this is the third installment of the premier Java conference for the Balkan region. It is an excellent effort by admirable husband and wife team Emo Abadjiev and Iva Abadjieva as well as the rest of the Java2Days team including Yoana Ivanova and Nadia Kostova. Thanks to their hard work, the conference continues to grow vigorously with almost a thousand enthusiastic, bright young people attending this year and no less than three tracks on Java, the Cloud and Mobile. The conference is a true gem in this region of the world and I am very proud to have been a part of it again, along with the other world class speakers the event rightfully attracts. It was my honor to present the first talk of the conference. It was a full-house session on Java EE 7 and 8 titled "JavaEE.Next(): Java EE 7, 8, and Beyond". The talk was primarily along the same lines as Arun Gupta's JavaOne 2012 technical keynote. I covered the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JCache, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1 and the rest of the APIs in Java EE 7. I also briefly talked about the possible contents of Java EE 8. My stretch goal was to gather some feedback on some open issues in the Java EE EG (more on that soon) but I ran out of time in the short format forty-five minute session. The talk was received well and I had some pretty good discussions afterwards. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman To my delight, the Java2Days folks were very interested in my domain-driven design/Java EE 6 talk (titled "Domain Driven Design with Java EE 6"). I've had this talk in my inventory for a long time now but it always gets overridden by less theoretical talks on APIs, tools, etc. The talk has three parts -- a brief overview of DDD theory, mapping DDD to Java EE and actual running DDD code in Java EE 6/GlassFish. For the demo, I converted the well-known DDD sample application (http://dddsample.sourceforge.net/) written mostly in Spring 2 and Hibernate 2 to Java EE 6. My eventual plan is to make the code available via a top level java.net project. Even despite the broad topic and time constraints, the talk went very well. It was a full house, the Q & A was excellent and one of the other speakers even told me they thought this was the best talk of the conference! The slides for the talk are here: Domain Driven Design with Java EE 6 from Reza Rahman The code examples are available here: https://blogs.oracle.com/reza/resource/dddsample.zip for now, as a simple zip file. Give me a shout if you would like to get it up and running. It was also a great honor to present the last session of the conference. It was a talk on the Java API for WebSocket/JSR 356 titled "Building HTML5/WebSocket Applications with JSR 356 and GlassFish". The talk is based on Danny Coward's JavaOne 2012 talk. The talk covers the basic of WebSocket, the JSR 356 API and a simple demo using Tyrus/GlassFish. The talk went very well and there were some very good questions afterwards. The slides for the talk are here: Building HTML5/WebSocket Applications with GlassFish and JSR 356 from Reza Rahman The code samples are available here: https://blogs.oracle.com/arungupta/resource/totd183-HelloWebSocket.zip. You'll need the latest promoted GlassFish 4 build to run the code. Give me a shout if you need help. Besides presenting my talks, I got to attend some great sessions on OSGi, HTML5, cloud, agile and Java 8. I got an invite to speak at the Macedonia JUG when possible. Victor Grazi of InfoQ wrote about my sessions and Java2Days here: http://www.infoq.com/news/2012/11/Java2DaysConference. Stoyan Rachev was very kind to blog about my sessions here: http://www.stoyanr.com/2012/11/java2days-2012-java-ee.html. I definitely enjoyed Java2Days 2012 and hope to be part of the conference next year!

• How do I cleanly design a central render/animation loop?

  - by mtoast

  I'm learning some graphics programming, and am in the midst of my first such project of any substance. But, I am really struggling at the moment with how to architect it cleanly. Let me explain. To display complicated graphics in my current language of choice (JavaScript -- have you heard of it?), you have to draw graphical content onto a <canvas> element. And to do animation, you must clear the <canvas> after every frame (unless you want previous graphics to remain). Thus, most canvas-related JavaScript demos I've seen have a function like this: function render() { clearCanvas(); // draw stuff here requestAnimationFrame(render); } render, as you may surmise, encapsulates the drawing of a single frame. What a single frame contains at a specific point in time, well... that is determined by the program state. So, in order for my program to do its thing, I just need to look at the state, and decide what to render. Right? Right. But that is more complicated than it seems. My program is called "Critter Clicker". In my program, you see several cute critters bouncing around the screen. Clicking on one of them agitates it, making it bounce around even more. There is also a start screen, which says "Click to start!" prior to the critters being displayed. Here are a few of the objects I'm working with in my program: StartScreenView // represents the start screen CritterTubView // represents the area in which the critters live CritterList // a collection of all the critters Critter // a single critter model CritterView // view of a single critter Nothing too egregious with this, I think. Yet, when I set out to flesh out my render function, I get stuck, because everything I write seems utterly ugly and reminiscent of a certain popular Italian dish. Here are a couple of approaches I've attempted, with my internal thought process included, and unrelated bits excluded for clarity. Approach 1: "It's conditions all the way down" // "I'll just write the program as I think it, one frame at a time." if (assetsLoaded) { if (userClickedToStart) { if (critterTubDisplayed) { if (crittersDisplayed) { forEach(crittersList, function(c) { if (c.wasClickedRecently) { c.getAgitated(); } }); } else { displayCritters(); } } else { displayCritterTub(); } } else { displayStartScreen(); } } That's a very much simplified example. Yet even with only a fraction of all the rendering conditions visible, render is already starting to get out of hand. So, I dispense with that and try another idea: Approach 2: Under the Rug // "Each view object shall be responsible for its own rendering. // "I'll pass each object the program state, and each can render itself." startScreen.render(state); critterTub.render(state); critterList.render(state); In this setup, I've essentially just pushed those crazy nested conditions to a deeper level in the code, hiding them from view. In other words, startScreen.render would check state to see if it needed actually to be drawn or not, and take the correct action. But this seems more like it only solves a code-aesthetic problem. The third and final approach I'm considering that I'll share is the idea that I could invent my own "wheel" to take care of this. I'm envisioning a function that takes a data structure that defines what should happen at any given point in the render call -- revealing the conditions and dependencies as a kind of tree. Approach 3: Mad Scientist renderTree({ phases: ['startScreen', 'critterTub', 'endCredits'], dependencies: { startScreen: ['assetsLoaded'], critterTub: ['startScreenClicked'], critterList ['critterTubDisplayed'] // etc. }, exclusions: { startScreen: ['startScreenClicked'], // etc. } }); That seems kind of cool. I'm not exactly sure how it would actually work, but I can see it being a rather nifty way to express things, especially if I flex some of JavaScript's events. In any case, I'm a little bit stumped because I don't see an obvious way to do this. If you couldn't tell, I'm coming to this from the web development world, and finding that doing animation is a bit more exotic than arranging an MVC application for handling simple requests - responses. What is the clean, established solution to this common-I-would-think problem?

  For the life of me, I can not get this to work. I can get MouseEnter, MouseLeave, and Click events to fire, but not MouseLeftButtonDown or MouseLeftButtonUp. Here's my XAML <UserControl x:Class="Dive.Map.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Canvas x:Name="LayoutRoot" MouseLeftButtonDown="LayoutRoot_MouseLeftButtonDown"> <Button x:Name="btnTest" Content="asdf" Background="Transparent" MouseLeftButtonDown="btnTest_MouseLeftButtonDown"></Button> </Canvas> </UserControl> And here's my code public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); } private void btnTest_MouseLeftButtonDown( object sender, MouseButtonEventArgs e ) { btnTest.Content = DateTime.Now.ToString(); } private void LayoutRoot_MouseLeftButtonDown( object sender, MouseButtonEventArgs e ) { e.Handled = false; } } What am I doing wrong?

• Marking Current Location on Map, Android

  - by deewangan

  Hi every one, i followed some tutorials to create an application that shows the current position of the user on the map with a marking. but for some reasons i can't get to work the marking part? the other parts works well, but whenever i add the marking code the application crashes. i hope someone could help me.here is the code: public class LocationActivity extends MapActivity { /** Called when the activity is first created. */ private MapView mapView; private LocationManager lm; private LocationListener ll; private MapController mc; GeoPoint p = null; Drawable defaultMarker = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mapView = (MapView)findViewById(R.id.mapView); //show zoom in/out buttons mapView.setBuiltInZoomControls(true); //Standard view of the map(map/sat) mapView.setSatellite(false); //get controller of the map for zooming in/out mc = mapView.getController(); // Zoom Level mc.setZoom(18); MyLocationOverlay myLocationOverlay = new MyLocationOverlay(); List<Overlay> list = mapView.getOverlays(); list.add(myLocationOverlay); lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); ll = new MyLocationListener(); lm.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, ll); //Get the current location in start-up GeoPoint initGeoPoint = new GeoPoint( (int)(lm.getLastKnownLocation( LocationManager.GPS_PROVIDER) .getLatitude()*1000000), (int)(lm.getLastKnownLocation( LocationManager.GPS_PROVIDER) .getLongitude()*1000000)); mc.animateTo(initGeoPoint); } protected class MyLocationOverlay extends com.google.android.maps.Overlay { @Override public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) { Paint paint = new Paint(); super.draw(canvas, mapView, shadow); // Converts lat/lng-Point to OUR coordinates on the screen.

• Require extended permissions in FBML pyfacebook app

  - by jlpp

  I'm trying to get my FBML canvas page to automatically prompt new app users for permission to publish_stream. Following Facebook's documentation I tried using the required_permissions argument to require_login. That is, I tried to use the pyfacebook require_login decorator like this: @facebook.require_login(required_permissions='publish_stream') as in: @decorator_from_middleware(FacebookMiddleware) @facebook.require_login(required_permissions='publish_stream') def canvas(request, template): ... Requesting extended permissions in a pyfacebook-based Facebook iFrame app has been discussed. Requesting extended permissions in an FBML app too. My objective is to require extended permissions in an FBML app. Am I missing something or can anyone suggest a workaround? Thanks.

• How to use html2canvas JavaScript with Selenium webdriver in C#

  - by PapyRef

  With selenium webdriver, I would test html2canvas JS script to take "screenshots" of webpages or parts of it, directly on the browser. I have a written this C# code to test it, but obj is always null. C# Code for reference IWebDriver Driver = new FirefoxDriver(); Driver.Navigate().GoToUrl("http://www.monsite.com"); string scriptJS = File.ReadAllText("html2canvas.js"); scriptJS += @" html2canvas(document.body, { onrendered: function(canvas) { var img = canvas.toDataURL("image/png"); return img; } });"; IJavaScriptExecutor executorJS = Driver as IJavaScriptExecutor; var obj = executorJS.ExecuteScript(scriptJS);

• How can I place a SurfaceView inside one or more scrollviews ?

  - by Mervin

  Hello, I'm making a 2D game for Android and I've encountered the following problem: - I have made a class that extends SurfaceView and draws my graphics (the size of the canvas that I use has to be 1664x864). This is ofcourse too big for the screen so I needed scrolling, I chose to use google's ScrollView and HorizontalScrollView (nested) for this, But whenever I add my SurfaceView to a ScrollView (whether it's 1 or 2) via AddChild it only draws the ScrollView , SurfaceCreated() isn't even called on the SurfaceView. (Drawing the SurfaceView in a layout without adding it to a ScrollView does work.) I realize that there are other options for scrolling like a screen-sized canvas and bitmap offsets but this would really be my preferred way to go. I would really appreciate some help to make this work.
