  • Why do you hate Java? Is it the language or the framework? [closed]

    - by zneak
    According to you all, Java is the third most-hated language here. The two other most hated languages are PHP and VBScript. (It's quite funny how they stand together on the podium.) I'd like to make it known that the question mostly addresses people who don't like Java. I assume here a number of subjective opinions as facts because they're usually considered true among people who don't like Java, and I don't want to be convinced otherwise here. If you're a Java enthusiast, you might find this question frustrating. It's never been made clear if people hate Java itself, or if they hate it because of the framework, or if it's a mixture of the two. On a side you have the language, where you have: the "everything should be an object" philosophy, even in instances where it should obviously be something else (event handlers I'm pointing you); checked exceptions; the idea that all logic should be presented as methods and properties is a big no-no; the fact that "closures" created by anonymous types only include final variables and arguments, but will allow write access to any member of the parent class; a few more. On the other side, you have the JDK, with... its load of inconsistencies and overengineering; monolithic class hierarchies; meaningless base exceptions like IOException (though other frameworks have similar exception hierarchies); sluggish responsiveness even with Swing; a few more. My question is, do you think that, if either one (Java or the JDK) was taken alone, and the other was dropped in favor of something else, the new combination would be better? For instance, if you could use the C# syntax with the JDK (adapting get*/set* methods into properties, and interfaces with only one method into delegates), or the Java syntax with the .NET Framework (doing the inverse transformations), would things get better in your opinion?

  • No "Choose OS" screen after co-installation of Ubuntu 12.04

    - by Léon McGregor
    I don't have any technical knowledge of Ubuntu but wanted to install it on a partition. Step-by-step of what i did. used disk management in windows 7 to clear 50gb of space used a usb live ubuntu 12.04 installer in custom install mode used the installer's built in disk manager to set up 2gb swap space and 48gb ext4 space ran installation, with option to copy over documents and settings from windows 7 restarted after completion. After this, my computer automatically loads ubuntu 12 and skips the option to load windows 7. i know the files are still there, as i can see them in the file manager. When trying to fix with the win7 installer dvd it tries to repair the OS in drive [D:] i.e. it recognises the disc itself as the OS and ignores the [c:] files. I think, after browsing around here, similar problems suggest this is a problem with the boot loader, but if the win7 dvd won't work, then i don't have any way to fix this. does anyone know of a way to force the computer to show a "choose OS" screen?

  • Stop Your Mouse from Waking Up Your Windows 7 Computer

    - by The Geek
    If you use Sleep Mode on your PC, have you ever noticed that moving your mouse will wake the computer from sleep mode? If you would prefer to only have the PC wake up when you hit a key instead, there’s a simple tweak. Just type Mouse into the start menu search box, or the Control Panel search box, and then open up the Mouse Properties panel. Find the Hardware tab, select your mouse in the list, and then click the Properties button. You’ll have to click the “Change settings” button before you can see the Power Management tab… And now, you can uncheck the box from “Allow this device to wake the computer”. That’s all there is to it.

  • New Packt Books: APEX & JRockit

    - by [email protected]
      I have received these 2 ebooks from Packt Publkishing and I am currently reviewing them. Both of them look great so far.   Oracle Application Express 3.2 - The Essentials and More First of all, I have to mention that I am new to APEX. I was interested on this product which is a development tool for Web applications on the Oracle Database. As I support JDeveloper and ADF, which are products that work very closely with the Oracle Database and are a rapid development tool as well, it is always interesting and useful to know complementary tools. APEX looks very useful and the book includes many working examples. A more complete review of this book is coming soon. Further information about this book can be seen at Packt.   Oracle JRockit: The Definitive Guide Many of our Oracle Coherence customers run their caches and clusters using JRockit. This JVM has helped us to solve lots of Service Requests. It is a really reliable, fast and stable JVM. It works great on both development and production environments with big amounts of data, concurrency, multi-threading and many other factors that can make a JVM crash. I must also mention JRockit Mission Control (JRMC), which is a great tool for management and monitoring. I really recommend it. As a matter of fact, some months ago, I created a document entitled "How to Monitor Coherence-Based Applications using JRockit Mission Control" (Doc Id 961617.1) on My Oracle Support. Also, the JRockit Runtime Analyzer (JRA) and it successor of newer versions, the JRockit Flight Recorder (JFR) are deeply reviewed. This book contains very clear and complete information about all this and more. I will post an entry with a more complete review soon (and will probably post an entry about Coherence monitoring with JRMC soon too). Further information about this book can be seen at Packt.

  • Warnings When Undo Isn't Possible

    - by ultan o'broin
    Enjoyed this post Never Use a Warning When you Mean Undo by Aza Raskin. It makes sense never to warn users if an undo option is possible. The examples given are from the web space. Here's the conclusion: Warnings cause us to lose our work, to mistrust our computers, and to blame ourselves. A simple but foolproof design methodology solves the problem: "Never use a warning when you mean undo." And when a user is deleting their work, you always mean undo. However, in enterprise apps you may find that an undo option isn't technically possible or desirable. Objects may be shared, part of a flow elsewhere, or undoing something committed to the database (a rollback I guess) may not be feasible if it becomes locked by another process. Plus, what constitutes user ownership of objects isn't always clear to users. The implications of delete (and other) actions need to be clearly communicated out in advance. Really, warnings are important in the enterprise space. Data has a very high value, and users can perform a wide variety of actions that may risk that data, not always within the application itself (at browser level, for example). That said, throwing warnings all over the place when an undo option is possible is annoying. Instead, treat warnings with respect. When there is no undo option possible, use warning messages to communicate potentially dangerous or irrecoverable actions or the downstream consequences of user actions on the process or task flow. Force the user to respond to a warning message by using a modal dialog with clearly labeled action buttons. Here's a couple of examples. A great article that got me thinking. Let's see more like that. Let's not forget there's more types of messages than just error messages. User assistance and user experience professionals need to understand when best to use confirmation, information, and warning types too!

  • How to have an improved relationship with recruiters?

    - by crosenblum
    I personally, always have problems with recruiter's and their constant spam.. I usually get tons of emails for jobs, not related to what I do. Or they have no idea what I do. Or they say they have a job in my field, but make me go thru hours of paperwork, only to find out they had no real job lead. Or my resume contained a keyword, that they searched for, but that keyword is like 1-10% of what I do, not my main job skill set. My point being is that I want to have a more polite, more accurate, less waste of each other's time. So I want to come up with a form letter, I can create in gmail to automatically send to all recruiter's, to help inform, educate and train them to deal better with me. That way, they know exactly what to send to me, so as to not waste my time. We don't play email/phone tag, just to find out they have no idea what I do, or how to find a job lead that matches that. I want this to be an improvement in my relationship and experience with recruiters, because honestly most of them waste my time. They call me at work, not considering I can't take phone call's at work, and they already had my email address. Mostly they annoy me, but I am tired of having to be rude to get my point across. I want them to immediately make sure they know what I can and have done, (Have you read my resume?) and have actual leads ready to be hired/interviewed soon or now. Any suggestions to how to improve the communication, to avoid wasting each other's time. I certainly hate having to come across as rude or improper, but when they just waste so much of my time, I don't know what else to do. So thank you for your time. Just to be clear, I want your help to write a form letter, that I can send to every recruiter that email's me, how to best work with me, and other people in IT/Web careers.

  • How can I fix the "TERM environment variable not set" warning in eclipse

    - by Robert
    I'm running ubuntu 12.04 LTS and working with eclipse (juno) on a c++ project. I keep getting "TERM environment variable not set" in the console while trying to run the program. I realize this means the variable needs to get set. My question is what should it be set to and how do I set it? I've read that it should be 'xterm' in a few places. So I added export TERM=xterm in my .profile and while eclipse stopped giving me the warning, instead it would output unreadable garbage everynow and then (not a side effect of the program). It did display the program output but intermixed were weird characters. This leads me to believe it's not 'xterm' I should be setting TERM to. Or I'm setting it in an incorrect way. Any help is appreciated. Sample output: **TERM environment variable not set.** Please make a selection ----------------------- 1. Create a budget 2. Edit a budget 3. Display a budget 4. Save a budget 5. Load a budget 6. Exit What is your selection: 1 **TERM environment variable not set.** Enter the name of your budget: etc The program continues to execute as expected but the message is highly annoying As someone has commented, I do use system("clear") which is likely the source of the warning? Either way, is this likely just an eclipse issue or something I can fix in ubuntu/linux

  • Animating Tile with Blitting taking up Memory.

    - by Kid
    I am trying to animate a specific tile in my 2d Array, using blitting. The animation consists of three different 16x16 sprites in a tilesheet. Now that works perfect with the code below. BUT it's causing memory leakage. Every second the FlashPlayer is taking up +140 kb more in memory. What part of the following code could possibly cause the leak: //The variable Rectangle finds where on the 2d array we should clear the pixels //Fillrect follows up by setting alpha 0 at that spot before we copy in nxt Sprite //Tiletype is a variable that holds what kind of tile the next tile in animation is //(from tileSheet) //drawTile() gets Sprite from tilesheet and copyPixels it into right position on canvas public function animateSprite():void{ tileGround.bitmapData.lock(); if(anmArray[0].tileType > 42){ anmArray[0].tileType = 40; frameCount = 0; } var rect:Rectangle = new Rectangle(anmArray[0].xtile * ts, anmArray[0].ytile * ts, ts, ts); tileGround.bitmapData.fillRect(rect, 0); anmArray[0].tileType = 40 + frameCount; drawTile(anmArray[0].tileType, anmArray[0].xtile, anmArray[0].ytile); frameCount++; tileGround.bitmapData.unlock(); } public function drawTile(spriteType:int, xt:int, yt:int):void{ var tileSprite:Bitmap = getImageFromSheet(spriteType, ts); var rec:Rectangle = new Rectangle(0, 0, ts, ts); var pt:Point = new Point(xt * ts, yt * ts); tileGround.bitmapData.copyPixels(tileSprite.bitmapData, rec, pt, null, null, true); } public function getImageFromSheet(spriteType:int, size:int):Bitmap{ var sheetColumns:int = tSheet.width/ts; var col:int = spriteType % sheetColumns; var row:int = Math.floor(spriteType/sheetColumns); var rec:Rectangle = new Rectangle(col * ts, row * ts, size, size); var pt:Point = new Point(0,0); var correctTile:Bitmap = new Bitmap(new BitmapData(size, size, false, 0)); correctTile.bitmapData.copyPixels(tSheet, rec, pt, null, null, true); return correctTile; }

  • Keeping Aspect Screen Ratio While Stays in Center

    - by David Dimalanta
    I sqw and I tried this suggestion on PISTACHIO BRAINSTORMIN* on how to make a good and adaptive screen ration. For every different screen size, let's say I put the perfect circle as a Texture in LibGDX and played it on screen. Here's the blueberry image example and it's perfectly rounded: When I played it on the Google Nexus 7, the circle turn into a slightly oblonng shape, resembling as it was being flatten a bit. Please observe this snapshot below and you can see the blueberry is almost but slightly not perfectly rounded: Now, when I tried the suggested code for aspect ratio, the perfect circle retained but another problem is occured. The problem is that I expecting for a view on center but instead it's been moved to the right offset leaving with a half black screen. This would be look like this: Here is my code using the suggested screen aspect ratio code: Class' Field // Ingredients Needed for Screen Aspect Ratio private static final int VIRTUAL_WIDTH = 720; private static final int VIRTUAL_HEIGHT = 1280; private static final float ASPECT_RATIO = ((float) VIRTUAL_WIDTH)/((float) VIRTUAL_HEIGHT); private Camera Mother_Camera; private Rectangle Viewport; render() // Camera updating... Mother_Camera.update(); Mother_Camera.apply(Gdx.gl10); // Reseting viewport... Gdx.gl.glViewport((int) Viewport.x, (int) Viewport.y, (int) Viewport.width, (int) Viewport.height); // Clear previous frame. Gdx.gl.glClearColor(0, 0, 0, 1); Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); show() Mother_Camera = new OrthographicCamera(VIRTUAL_WIDTH, VIRTUAL_HEIGHT); Was this code useful for screen aspect ratio-proportion fixing or it is statically dependent on actual device's width and height? *see http://blog.acamara.es/2012/02/05/keep-screen-aspect-ratio-with-different-resolutions-using-libgdx/#comment-317

  • XNA - Render texture to a rendertarget 2d via SpriteBatch error

    - by Jared B
    I got simple code that uses SpriteBatch to draw a texture onto a RenderTarget2D... private void drawScene(GameTime g) { GraphicsDevice.Clear(skyColor); GraphicsDevice.SetRenderTarget(targetScene); drawSunAndMoon(); effect.Fog = true; GraphicsDevice.SetVertexBuffer(line); effect.MainEffect.CurrentTechnique.Passes[0].Apply(); GraphicsDevice.DrawPrimitives(PrimitiveType.TriangleStrip, 0, 2); GraphicsDevice.SetRenderTarget(null); SceneTexture = targetScene; } private void drawPostProcessing(GameTime g) { effect.SceneTexture = SceneTexture; GraphicsDevice.SetRenderTarget(targetBloom); spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Opaque, null, null, null); { if(Bloom) effect.BlurEffect.CurrentTechnique.Passes[0].Apply(); spriteBatch.Draw(targetScene, new Rectangle(0, 0, Window.ClientBounds.Width, Window.ClientBounds.Height), Color.White); } spriteBatch.End(); BloomTexture = targetBloom; GraphicsDevice.SetRenderTarget(null); } Both methods are called from Draw(GameTime gameTime). First drawScene is called, then drawPostProcessing is called. The thing is, I can't run the code because "the render target must not be set on the device when it is used as a texture." at line spriteBatch.Draw(targetScene, new Rectangle(0, 0, Window.ClientBounds.Width, Window.ClientBounds.Height), Color.White); I already found the solution, which is to draw the actual renderTarget (targetScene) to the texture so it doesn't create a reference to the loaded rendertarget. However, to my knowledge, the only way of doing this is to write: GraphicsDevice.SetRenderTarget(OutputTarget) SpriteBatch.Draw(InputTarget, ...) GraphicsDevice.SetRenderTarget(null) Which encounters the same exact problem I'm having right now. So, the question I'm asking is: how would I render InputTarget to OutputTarget without reference issues?

  • Bizarre image loading problem from apache2

    - by NateDSaint
    Users have complained a few times about seeing a bizarre set of pink or green stripes on our webpage. At first I thought there were a rash of video card outages, but then someone sent me a screenshot from their browser (IE8). I later saw the same thing, but with slightly different colors on Chrome. Users have experienced this on their iPads and iPhones (iOS Safari). Because I've optimized the site to cache images, the bad image stays around until you clear your cache, so once you do, it resolves itself. My assumption is that the transmission of the image is being cut off mid-stream and then staying that way, but I can't for the life of me figure out why. Here's what I've checked: Header length is being sent, and transmission looks okay (wget sample below): wget http://www.superiorlivestock.com/templates/sla2/images/wallbg2.jpg --2012-04-05 08:46:00-- http://www.superiorlivestock.com/templates/sla2/images/wallbg2.jpg Resolving www.superiorlivestock.com (www.superiorlivestock.com)...

  • apply non-hierarchial transforms to hierarchial skeleton?

    - by user975135
    I use Blender3D, but the answer might not API-exclusive. I have some matrices I need to assign to PoseBones. The resulting pose looks fine when there is no bone hierarchy (parenting) and messed up when there is. I've uploaded an archive with sample blend of the rigged models, text animation importer and a test animation file here: http://www.2shared.com/file/5qUjmnIs/sample_files.html Import the animation by selecting an Armature and running the importer on "sba" file. Do this for both Armatures. This is how I assign the poses in the real (complex) importer: matrix_bases = ... # matrix from file animation_matrix = matrix_basis * pose.bones['mybone'].matrix.copy() pose.bones[bonename].matrix = animation_matrix If I go to edit mode, select all bones and press Alt+P to undo parenting, the Pose looks fine again. The API documentation says the PoseBone.matrix is in "object space", but it seems clear to me from these tests that they are relative to parent bones. Final 4x4 matrix after constraints and drivers are applied (object space) I tried doing something like this: matrix_basis = ... # matrix from file animation_matrix = matrix_basis * (pose.bones['mybone'].matrix.copy() * pose.bones[bonename].bone.parent.matrix_local.copy().inverted()) pose.bones[bonename].matrix = animation_matrix But it looks worse. Experimented with order of operations, no luck with all. For the record, in the old 2.4 API this worked like a charm: matrix_basis = ... # matrix from file animation_matrix = armature.bones['mybone'].matrix['ARMATURESPACE'].copy() * matrix_basis pose.bones[bonename].poseMatrix = animation_matrix pose.update() Link to Blender API ref: http://www.blender.org/documentation/blender_python_api_2_63_17/bpy.types.BlendData.html#bpy.types.BlendData http://www.blender.org/documentation/blender_python_api_2_63_17/bpy.types.PoseBone.html#bpy.types.PoseBone

  • How to recover data from a failing hard drive?

    - by intuited
    An external 3½" HDD seems to be in danger of failing — it's making ticking sounds when idle. I've acquired a replacement drive, and want to know the best strategy to get the data off of the dubious drive with the best chance of saving as much as possible. There are some directories that are more important than others. However, I'm guessing that picking and choosing directories is going to reduce my chances of saving the whole thing. I would also have to mount it, dump a file listing, and then unmount it in order to be able to effectively prioritize directories. Adding in the fact that it's time-consuming to do this, I'm leaning away from this approach. I've considered just using dd, but I'm not sure how it would handle read errors or other problems that might prevent only certain parts of the data from being rescued, or which could be overcome with some retries, but not so many that they endanger other parts of the drive from being saved. I guess ideally it would do a single pass to get as much as possible and then go back to retry anything that was missed due to errors. Is it possible that copying more slowly — e.g. pausing every x MB/GB — would be better than just running the operation full tilt, for example to avoid any overheating issues? For the "where is your backup" crowd: this actually is my backup drive, but it also contains some non-critical and bulky stuff, like music, that aren't backups, i.e. aren't backed up. The drive has not exhibited any clear signs of failure other than this somewhat ominous sound. I did have to fsck a few errors recently — orphaned inodes, incorrect free blocks/inodes counts, inode bitmap differences, zero dtime on deleted inodes; about 20 errors in all. The filesystem of the partition is ext3.

  • PC On/Off Time Charts Windows Uptime; No Logging Necessary

    - by Jason Fitzpatrick
    Windows: PC On/Off Time is a graphical tool that displays your PC’s uptime, downtime, errors, and more all in a clear and portable package. One of the hassles of using logging tools is that you usually have to enable the logging and then wait for results to pile up before seeing anything useful (such as when you turn on the logging on your router). PC On/Off Time taps right into the event logs your Windows PC is already keeping so you get immediate access to your uptime history. If you look at the screenshot above you can see an accurate picture of the last few weeks of uptime on my computer. October 23-24 I didn’t boot down my PC, the rest of the time I hibernated it overnight when I wasn’t using it, November 1st I installed an SSD (you can see the burst of reboots and short uptimes) and then November 9th there was a brief power outage that caused an unexpected stop (the red arrows on the timeline for the 9th). The free version offers a three-week peek back into your uptime history (upgrade to the Pro version for $12.75 or for free using Trial Pay to unlock your completely uptime history).PC On/Off Time is Windows only.

  • Design for XML mapping scenarios between two different systems [on hold]

    - by deepak_prn
    Mapping XML fields between two systems is a mundane routine in integration scenarios. I am trying to make the design documents look better and provide clear understanding to the developers especially when we do not use XSLT or any other IDE such as jDeveloper or eclipse plugins. I want it to be a high level design but at the same time talk in developer's language. So that there is no requirements that slip under the crack. For example, one of the scenarios goes: the store cashier sells an item, the transaction data is sent to Data management system. Now, I am writing a functional design for the scenario which deals with mapping XML fields between our system and the data management system. Question : I was wondering if some one had to deal with mapping XML fields between two systems? (without XSLT being involved) and if you used a table to represent the fields mapping (example is below) or any other visualization tool which does not break the bank ? I am trying to find out if there is a better way to represent XML mapping in your design documents. The widely accepted and used method seems to be using a simple table such as in the picture to illustrate the mapping. I am wondering if there are alternate ways/ tools to represent such as in Altova:

This would be look like this: Here is my code using the suggested screen aspect ratio code: Class' Field // Ingredients Needed for Screen Aspect Ratio private static final int VIRTUAL_WIDTH = 720; private static final int VIRTUAL_HEIGHT = 1280; private static final float ASPECT_RATIO = ((float) VIRTUAL_WIDTH)/((float) VIRTUAL_HEIGHT); private Camera Mother_Camera; private Rectangle Viewport; render() // Camera updating... Mother_Camera.update(); Mother_Camera.apply(Gdx.gl10); // Reseting viewport... Gdx.gl.glViewport((int) Viewport.x, (int) Viewport.y, (int) Viewport.width, (int) Viewport.height); // Clear previous frame. Gdx.gl.glClearColor(0, 0, 0, 1); Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); show() Mother_Camera = new OrthographicCamera(VIRTUAL_WIDTH, VIRTUAL_HEIGHT); Was this code useful for screen aspect ratio-proportion fixing or it is statically dependent on actual device's width and height? *see http://blog.acamara.es/2012/02/05/keep-screen-aspect-ratio-with-different-resolutions-using-libgdx/#comment-317

  • When does a Project Manager start in a project?

    - by johndoucette
    From a colleague of mine… “As a project manager, when do you typically like to get initially involved in the project? Is it better for the PM to be rolled on during the project kick-off, the first week, or is it better to roll-on the second week when things settle down?” My textbook answer is “the Project Manager is responsible for the successful completion and delivery of the expected outcome of the project through the following major tasks;” 1.    Identifying requirements 2.    Establishing clear and achievable objectives 3.    Balancing the competing demands for quality, scope, time, and cost 4.    Adapting the specifications, plans, and approach to the different concerns and expectations of the various stakeholders However; My colleague is often a lead technical consultant coming into a project alone to help a client solve a complex problem. As Magenic consultants, we all possess many of the “project managing” skills I talked about above and tend to be responsible for item #1 and #2 as well as the actual architecture/design tasks early in a project. When the real development begins and there is no PM involved, the project will quickly get harder to execute unless items #3 & #4 are assigned to a Project Manager. In software development, the concept of context switching between coding and other administrative activities is the hardest skill perfect. In my experience, I have rarely been introduced to someone who has mastered this skill. This is the limbo I was in when I was asked to become a PM -- while still developing. “Put down the code” was not only a profound statement, but looking back – a necessary one. Unless you are lucky to have found that one developer who is a superman, asking your developers (internal corporate or consultant) to perform #3 and #4 tasks, will surely take more time, allow opportunity for more scope, and eventually cost more. Project Managers are crucial to the overall success of a project, and I prefer them to start by taking ownership of delivery on day one.

  • How can a non-technical person can learn to write a spec for small projects?

    - by Joseph Turian
    How can a non-technical person learn to write specs for small projects? A friend of mine is trying to outsource some development on a statistics project. In particular, he does a lot of work in excel, and wants to outsource the creation of scripts to do what he now does by hand. However, my friend is extremely non-technical. He is poor at writing technical specs. When he does write a spec, it is written the way you would describe doing something in excel (go to this cell and then copy the value to that cell). It is also overly verbose, and does examples several times. I'm not sure if he properly describes corner cases. The first project he outsourced was a failure. I think he overdescribed some details, but underdescribed corner cases. That and/or the coder he hired didn't think through the corner cases and ask appropriate questions. I'm not sure. I got on IM with him and it took me half an hour to dig out a description that should have taken five minutes or less to describe. I wrote the scripts for him at the end, but didn't examine why his process with the coder failed. He has asked me for help. However, I refuse to get involved, because taking his spec and translating it into clear requirements is 10x more work than executing on a clearly written spec. What is the right way for him to learn? Are there resources he could use? Are there ways he can learn from small, low-pressure practice projects with coders? [edit: Most of his scripts are statistical and data processing oriented. e.g. take this column and run an average over it. Remove these rows under these conditions. So the challenge is different than spec'ing a web app.]

  • Is HTML5/WebGL performance unreliable on low-end Android tablets and phones?

    - by Boris van Schooten
    I've developed a couple of WebGL games, and am trying them out on Android. I found that they run very slowly on my tablet, however. For example, a game with 10 sprites or so runs as 5fps. I tried Chrome and CocoonJS, but they are comparably slow. I also tried other games, and even games with only 5 or so moving sprites are this slow. This seems inconsistent with reports from others, such as this benchmark. Typically, when people talk about HTML5 game performance, they mention well-known and higher-end phones and tables. While my 7" tablet is cheap (I believe it's a relabeled Allwinner tablet, apparently with the Mali 400 GPU), I found it generally has a good gaming performance. All the games I tried run smoothly. I also developed an OpenGL ES 2 demo with 200 shaded 3D objects, and it ran at 50fps. My suspicion is that many low-end and white-label devices may have unacceptable HTML5/WebGL support, which means there may be a large section of gamers you will not reach when you choose this as your platform. I've heard rumors about inconsistent performance of HTML5 and WebGL on different devices, but no clear picture emerges. I would like to hear if any of you have had similar experiences with HTML5 or WebGL, or whether I can find information about the percentage of devices I can expect to have decent performance.

  • Box2D: How to get the Exact Collision Point and ignore the collision (from 2 "ghost bodies")

    - by Moritz
    I have a very basic problem with Box2D. For a arenatype game where you can throw scriptable "missiles" at other players I decided to use Box2D for the collision detection between the players and the missiles. Players and missiles have their own circular shape with a specific size (varying). But I don´t want to use dynamic bodies because the missiles need to move themselve in any way they want to (defined in the script) and shouldnt be resolved unless the script wants it. The behavior I look for is as following (for each time step): velocity of missiles is set by the specific missile script each missile is moved according to that velocity if a collision accurs now, I want to get the exact position of impact, and now I need a mechanism to decide if the missile should just ignore the collision (for example collision between two fireballs which shouldnt interact) or take it (so they are resolved and dont overlap anymore) So is there a way in Box2D to create Ghost bodies and listen to collisions from them, then deciding if they should ignore the collision or should take them and resolve their position? I hope I was clear enough and would be happy about any help!

  • Is there an established or defined best practice for source control branching between development and production builds?

    - by Matthew Patrick Cashatt
    Thanks for looking. I struggled in how to phrase my question, so let me give an example in hopes of making more clear what I am after: I currently work on a dev team responsible for maintaining and adding features to a web application. We have a development server and we use source control (TFS). Each day everyone checks in their code and when the code (running on the dev server) passes our QA/QC program, it goes to production. Recently, however, we had a bug in production which required an immediate production fix. The problem was that several of us developers had code checked in that was not ready for production so we had to either quickly complete and QA the code, or roll back everything, undo pending changes, etc. In other words, it was a mess. This made me wonder: Is there an established design pattern that prevents this type of scenario. It seems like there must be some "textbook" answer to this, but I am unsure what that would be. Perhaps a development branch of the code and a "release-ready" or production branch of the code?
