• Could I be going crazy with Event Handlers? Am I going the "wrong way" with my design?

  - by sensae

  I guess I've decided that I really like event handlers. I may be suffering a bit from analysis paralysis, but I'm concerned about making my design unwieldy or running into some other unforeseen consequence to my design decisions. My game engine currently does basic sprite-based rendering with a panning overhead camera. My design looks a bit like this: SceneHandler Contains a list of classes that implement the SceneListener interface (currently only Sprites). Calls render() once per tick, and sends onCameraUpdate(); messages to SceneListeners. InputHandler Polls the input once per tick, and sends a simple "onKeyPressed" message to InputListeners. I have a Camera InputListener which holds a SceneHandler instance and triggers updateCamera(); events based on what the input is. AgentHandler Calls default actions on any Agents (AI) once per tick, and will check a stack for any new events that are registered, dispatching them to specific Agents as needed. So I have basic sprite objects that can move around a scene and use rudimentary steering behaviors to travel. I've gotten onto collision detection, and this is where I'm not sure the direction my design is going is good. Is it a good practice to have many, small event handlers? I imagine going the way I am that I'd have to implement some kind of CollisionHandler. Would I be better off with a more consolidated EntityHandler which handles AI, collision updates, and other entity interactions in one class? Or will I be fine just implementing many different event handling subsystems which pass messages to each other based on what kind of event it is? Should I write an EntityHandler which is simply responsible for coordinating all these sub event handlers? I realize in some cases, such as my InputHandler and SceneHandler, those are very specific types of events. A large portion of my game code won't care about input, and a large portion won't care about updates that happen purely in the rendering of the scene. Thus I feel my isolation of those systems is justified. However, I'm asking this question specifically approaching game logic type events.

• Why occlusion is failing sometimes?

  - by cad

  I am rendering two cubes in the space using XNA 4.0 and occlusion only works from certain angles. Here is what I see from the front angle (everything ok) Here is what I see from behind This is my draw method. Cubes are drawn by serverManager and serverManager1 protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); switch (_gameStateFSM.State) { case GameFSMState.GameStateFSM.INTROSCREEN: spriteBatch.Begin(); introscreen.Draw(spriteBatch); spriteBatch.End(); break; case GameFSMState.GameStateFSM.GAME: spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend); // Text screenMessagesManager.Draw(spriteBatch, firstPersonCamera.cameraPosition, fpsHelper.framesPerSecond); // Camera firstPersonCamera.Draw(); // Servers serverManager.Draw(GraphicsDevice, firstPersonCamera.viewMatrix, firstPersonCamera.projMatrix); serverManager1.Draw(GraphicsDevice, firstPersonCamera.viewMatrix, firstPersonCamera.projMatrix); // Room //roomManager.Draw(GraphicsDevice, firstPersonCamera.viewMatrix); spriteBatch.End(); break; case GameFSMState.GameStateFSM.EXITGAME: break; default: break; } base.Draw(gameTime); fpsHelper.IncrementFrameCounter(); } serverManager and serverManager1 are instances of the same class ServerManager that draws a cube. The draw method for ServerManager is: public void Draw(GraphicsDevice graphicsDevice, Matrix viewMatrix, Matrix projectionMatrix) { cubeEffect.World = Matrix.CreateTranslation(modelPosition); // Set the World matrix which defines the position of the cube cubeEffect.View = viewMatrix; // Set the View matrix which defines the camera and what it's looking at cubeEffect.Projection = projectionMatrix; // Enable textures on the Cube Effect. this is necessary to texture the model cubeEffect.TextureEnabled = true; cubeEffect.Texture = cubeTexture; // Enable some pretty lights cubeEffect.EnableDefaultLighting(); // apply the effect and render the cube foreach (EffectPass pass in cubeEffect.CurrentTechnique.Passes) { pass.Apply(); cubeToDraw.RenderToDevice(graphicsDevice); } } Obviously there is something I am doing wrong. Any hint of where to look? (Maybe z-buffer or occlusion tests?)

• Website directory structure regarding subdomains, www, and "global" content

  - by Pawnguy7

  I am trying to make a homemade HTTP server. It occurs to me, though, I never fully understood what you might call "relativity" among web pages. I have come across that www. is a subdomain, and I understand its original purpose. IT sounds like, in general, you would redirect (is that 301 or 302?) it to a... non-subdomain, sort of. As in, redirecting www.example.com to example.com. I am not entirely sure how to make this work when retrieving files for an HTTP server though. I would assume that example.com would be the root, and www manifests as a folder within it. I am unsure. There is also the question of multi-level subdomains, e.g. subdomain2.subdomain1.example.com. It seems to me they are structured "backwards", where you go from the root left in folder structure. In this situation, subdomain2 is a directory within subdomain1, which is a directory in the root. Finally, it occurs to me I might want a sort of global location. For example, maybe all subdomains still use an image as a logo. It makes more sense to me that there is one image, rather than each having a copy. In the same way, albiet more doubtfully, you might have global CSS (though that is a bit contrary to the idea of a subdomain in the first place), or a javascript that is commonly used. (more efficient than each having its copy and better for organization purposes). Finally, mabye you have a global 404 page. I think this might be the case where you have user-created subdomains (say bloggername.example.com), where example.com still has a default 404 when either a subdomain does not exist or page does not exists under a valid blogger. I am confused on what the directory structure for this should be. To summarize: Should and how it have a global files not in a subdirectory, how should www. be handled, (or how a now www or other subdomain should be handled), and the pattern for root/subdomain, as well as subdomain within subdomains (order-wise). Sorry this is multiple questions, but I feel at the root they are all related to the directory.

• jQuery slide open and close menus. How to stop them going crazy? [closed]

  - by firefusion

  I want sub menu's of a verticle menu to expand and collapse when moused over. This is what i've got so far but it goes crazy if you do it to quick as all the animations run at once and on a delay. How can i make sure just one menu expands at a time. I've also set the current_page_item to be open but default and I don't want this to expand or collaspe. <ul> <li class="current_page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a> <ul class="children"> <li class="page_item"><a href="#">Child page</a></li> <li class="page_item"><a href="#">Child page</a></li> </ul> </li> <li class="page_item"><a href="#">Parent Item</a></li> <li class="page_item"><a href="#">Parent Item</a></li> </ul> jQuery('ul.children').hide(); jQuery('li.current_page_item ul.children').show(); jQuery('li.current_page_item').parent().show(); jQuery("li.page_item").hover(function() { jQuery(this).find('ul.children').delay(300).slideDown('slow'); }, function() { jQuery(this).find('ul.children').delay(300).slideUp('slow'); });

• Determining whether a visitor reached two different pages in one visit

  - by Shaun

  I have a funnel that I would like to track. Tracking this funnel won't work with the default "goal funnel" tracking in Google due to the fact that I am mixing events and pageviews. As such, I've created a series of reports: Visits to demo pages - An inclusion filter on "Page". Triggers an Event on these pages - An inclusion filter on "Page" and "Event Category". Does not bounce - An inclusion filter on "Page" and an exclusion filter on "Exit Page" for these same pages. Reach our storefront - ?? Purchase something - An inclusion filter on "Page" and a report that shows "Transactions". At a basic level, I need to track users who reached demo pages, then reached any page on our store. Intuitively, I created a segment, used two inclusive "Page" filters (one for the demo pages and one for any page in our store), and combined them with an "AND" operator. I thought this was working until I tried to do the same thing in a dashboard widget and on a custom report. When I tried the same thing in those areas, I got zero results. I figured this might be because widgets and custom report filters function differently from segment filters (the options are different for all of them), so I tried applying my "demo page && store page" segment to a report that gave me a general page list. All I saw was a list of the specific pages. I tried simplifying things by creating a custom report that showed all visits to store pages, then applied a segment that filtered for users who visited demo pages. This got me the same numbers as my "demo page && store page" segment, but showed a list of demo pages. This has led me to believe that the "demo page && store page segment" approach and the "demo segment && store report" functionally behave the same. However, this experience has left me questioning whether they're giving me what I want. Are these methods showing me all users who reached both sets of pages? Is there a better/easier/more standard way of doing this aside from looking at visitor flow reports? I'm trying to avoid a combination of custom variables/events and using the horizontal funnel approach since it would consume a large number of our limited goals and seems more complicated than is necessary for tracking this funnel.

• Boot error aftter clean Ubuntu 13.04 install: [Reboot and select proper boot device]

  - by IcarusNM

  I am having the same problem as this guy where a fresh Ubuntu install completes beautifully but will not boot. I get the ASUS (?) "Reboot and select proper boot device" error, first with Xubuntu 13.10 and after finally giving up there, and Xubuntu 13.4, I am back to regular Ubuntu 13.4. ASUS motherboard Z77, Intel chipset. Standard internal SATA 500GB HD. 64-bit. All-new hardware less than 3 months old. It was running Ubuntu 12.04LTC great until I tried this upgrade. I have re-installed from scratch every which way: with LVM, without LVM; with the default partitions, with my own partitions. With ext3 or ext4. Alongside; replace; upgrade. No difference. On the last two tries, I have booted afterward from the same USB stick, downloaded and run boot-repair, and now I guess I am off to the boot-repair support email with my URLs from that. It did all kinds of cool stuff but ultimately made no difference. I never got anything like this with Ubuntu 12.04. I've now probably re-installed Ubuntu 13.04 ten times slightly different ways. I finally found how to skip the language packs, so at least that sped things up! :) This starts from the ubuntu-13.04-desktop-amd64.iso and UNetbootin as suggested on the official instructions for USB thumb drive creation from OSX. That part all works fine (booting the USB on the PC and trying Ubuntu and/or installing from there on the PC HD.) I have no CD drive on this PC, but I suppose I could get one. I would rather find some Linux install that works from USB like I've always done. After running boot-repair twice, in the ASUS BIOS I now see three different UEFI boot options in the priority list, and they are all labeled exactly the same: ubuntu (P6: WDC WD5000AAKX-00U6AA0) Then there's a non-UEFI option: P6: WDC WD5000AAKX-00U6AA0 (476940MB) And a fifth option appeared after the first boot-repair: Windows Boot Manager (P6: WDC WD5000AAKX-00U6AA0) I have tried all 5 of these, and I get exactly the same error. I have never had Windows installed on this HD. ASUS is calling it Windows Boot Manaer but I presume that's a mistaken label for whatever boot-repair did. I can boot on USB and run GParted and it looks great. The partitions all look normal. I found another case of this online with no solution posted. I can't find much about it online. Needs a Master Boot Record wipe/redo?? I'm not sure how.

• Notes - Part I - Say Hello from Java

  - by Silviu Turuga

  Sometimes we need to take small notes to remember things, one way to do this is to use stick notes and have them all around our desktop. But what happening if you have a lot of notes and a small office? You'll need a piece of software that will sort things for you and also it will provide you a quick way to retrieve the notes when need. Did I mention that this will keep your desktop clean and also will reduce paper waste? During the next days we'll gonna create an application that will let you manage your notes, put them in different categories etc. I'll show you step by step what do you need to do and finally you'll have the application run on multiple systems, such as Mac, Windows, Linux, etc. The only pre-requisition for this lesson is to have JDK 7 with JavaFX installed and an IDE, preferably NetBeans. I'll call this application Notes…. Part I - Say Hello from Java  From NetBeans go to Files->New Project Chose JavaFX->JavaFX FXML Application Project Name: Notes FXML name: NotesUI Check Create Application Class and name it Main After this the project is created and you'll see the following structure As a best practice I advice you to have your code in your own package instead of the default one. right click on Source Packages and chose New->Java Package name it something like this: com.turuga.notes and click Next after the package is created, select all the 3 files from step #3 and drag them over the new package chose Refactor, as this will make sure all the references are correctly moved inside the new package now you should have the following structure if you'll try to run the project you'll get an error: Unable to find class: Main right click on project name Notes and click properties go to Run and you'll see Application Class set to Main, but because we have defined our own packages, this location has been change, so click on Browse and the correct one appear: com.turuga.notes.Main last modification before running the project is to right click on NotesUI.fxml and chose Edit (if you'll double click it will open in JavaFX Scene Builder) look around line 9 and change fx:controller="NotesUIController" to fx:controller="com.turuga.notes.NotesUIController" now you are ready to run it and you should see the following On the next lesson we'll continue to play with NetBeans and start working on the interface of our project

• How does the fstab 'defaults' option work? Is relatime recommended?

  - by hushs

  I know the fstab defaults option means this: rw,suid,dev,exec,auto,nouser,async. But what if I want to add one more option, for example relatime, should I still add defaults too or they are applied anyway? Is it needed to add at least one option? Some examples: 1. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 defaults 0 2 2. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 0 2 3. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 defaults,relatime 0 2 4. UUID=bfb42838-d866-4233-9679-96e7536356df /media/data ext3 relatime 0 2 Is the (2) correct(no option at all)? Are the (1) and (2) the same? Are the (3) and (4) the same? Furthermore, I read in the Ubuntu Community Documentation that in Ubuntu 8.04 relatime was used as default for linux native file systems. Is it still true for 12.04? If yes, then why do I see this if I use the mount command: /dev/sda2 on / type ext4 (rw,errors=remount-ro) If no, why not? It isn't recommended to use relatime now? I just wanted to apply it to my non system partitions, it is a good idea? EDIT: I found an other command to list the mounted partitions and their options: cat /proc/mounts This is the result of a partition mounted with the defaults option in fstab: /dev/sdb2 /media/adat ext3 rw,relatime,errors=continue,barrier=1,data=ordered 0 0 This is the output of mount for the same partition: /dev/sdb2 on /media/adat type ext3 (rw) And here is both result if the same partition mounted from Nautilus as a non-root user: /dev/sdb2 /media/adat ext3 rw,nosuid,nodev,relatime,errors=continue,barrier=1,data=ordered 0 0 /dev/sdb2 on /media/adat type ext3 (rw,nosuid,nodev,uhelper=udisks) So it looks like relatime is used if we mount an ext partition in 12.04. So it is unneeded to add it manually. So my problem is broadly solved. But I still can't see why the options that should be in the defaults are not listed even with the cat /proc/mounts. Maybe there is a third and even better method to list the partition mount options :)

• ExplorerCanvas and JQuery

  - by PhubarBaz

  I am working on a Javascript app (CloudGraph) that uses HTML5 canvas and JQuery. I'm using ExplorerCanvas to support canvas in IE. I recently came across an interesting problem. What I was trying to do is restore the user's settings when the page is loaded. I read some information from a cookie that I set the last time the user accessed the application. One of these settings is the size of the canvas. I decided that the best place to do this would be when the document is ready using JQuery $(document).ready(). This worked fine in browsers that natively support the canvas element. But in IE it kept getting errors the first time I would hit the page. It seemed that the excanvas element wasn't initialized yet because I was getting null reference and unknown properties errors. If I refreshed the page the errors went away but the resized canvas wasn't drawing on the entire area of the canvas. It was like the clipping rectangle was still set to the default canvas size. I found that the canvas element when using excanvas has a div child element which is where the actual drawing takes place. When I changed the width and height of the canvas element in document.ready it didn't change the width and height of the child div. Initially my solution was to also change the div element when changing the canvas element and that worked. But then I realized that having to refresh the page every time I started the app in IE really sucked. That wouldn't be acceptable for users. Since it seemed like the canvas wasn't getting initialized before I was trying to use it I decided to try to initialize my app at a different time. I figured the next best place was in the onload event. Sure enough, moving my initialization to onload fixed all of the problems. So, it looks like the canvas shouldn't be manipulated until the onload event when using ExplorerCanvas. There might be ways to do it when the document is ready. I found some posts on initializing excanvas manually, but for me waiting until onload worked just fine.

• How to do proper Alpha in XNA?

  - by Soshimo

  Okay, I've read several articles, tutorials, and questions regarding this. Most point to the same technique which doesn't solve my problem. I need the ability to create semi-transparent sprites (texture2D's really) and have them overlay another sprite. I can achieve that somewhat with the code samples I've found but I'm not satisfied with the results and I know there is a way to do this. In mobile programming (BREW) we did it old school and actually checked each pixel for transparency before rendering. In this case it seems to render the sprite below it blended with the alpha above it. This may be an artifact of how I'm rendering the texture but, as I said before, all examples point to this one technique. Before I go any further I'll go ahead and paste my example code. public void Draw(SpriteBatch batch, Camera camera, float alpha) { int tileMapWidth = Width; int tileMapHeight = Height; batch.Begin(SpriteSortMode.Texture, BlendState.AlphaBlend, SamplerState.PointWrap, DepthStencilState.Default, RasterizerState.CullNone, null, camera.TransformMatrix); for (int x = 0; x < tileMapWidth; x++) { for (int y = 0; y < tileMapHeight; y++) { int tileIndex = _map[y, x]; if (tileIndex != -1) { Texture2D texture = _tileTextures[tileIndex]; batch.Draw( texture, new Rectangle( (x * Engine.TileWidth), (y * Engine.TileHeight), Engine.TileWidth, Engine.TileHeight), new Color(new Vector4(1f, 1f, 1f, alpha ))); } } } batch.End(); } As you can see, in this code I'm using the overloaded SpriteBatch.Begin method which takes, among other things, a blend state. I'm almost positive that's my problem. I don't want to BLEND the sprites, I want them to be transparent when alpha is 0. In this example I can set alpha to 0 but it still renders both tiles, with the lower z ordered sprite showing through, discolored because of the blending. This is not a desired effect, I want the higher z-ordered sprite to fade out and not effect the color beneath it in such a manner. I might be way off here as I'm fairly new to XNA development so feel free to steer me in the correct direction in the event I'm going down the wrong rabbit hole. TIA

• Keeping the meshes "thickness" the same when scaling an object

  - by user1806687

  I've been bashing my head for the past couple of weeks trying to find a way to help me accomplish, on first look very easy task. So, I got this one object currently made out of 5 cuboids (2 sides, 1 top, 1 bottom, 1 back), this is just for an example, later on there will be whole range of different set ups. Now, the thing is when the user chooses to scale the whole object this is what should happen: X scale: top and bottom cuboids should get scaled by a scale factor, sides should get moved so they are positioned just like they were before(in this case at both ends of top and bottom cuboids), back should get scaled so it fits like before(if I simply scale it by a scale factor it will leave gaps on each side). Y scale: sides should get scaled by a scale factor, top and bottom cuboid should get moved, and back should also get scaled. Z scale: sides, top and bottom cuboids should get scaled, back should get moved. Hope you can help, EDIT: So, I've decided to explain the situation once more, this time more detailed(hopefully). I've also made some pictures of how the scaling should look like, where is the problem and the wrong way of scaling. I this example I will be using a thick walled box, with one face missing, where each wall is made by a cuboid(but later on there will be diffrent shapes of objects, where a one of the face might be roundish, or triangle or even under some angle), scaling will be 2x on X axis. 1.This is how the default object without any scaling applied looks like: http://img856.imageshack.us/img856/4293/defaulttz.png 2.If I scale the whole object(all of the meshes) by some scale factor, the problem becomes that the "thickness" of the object walls also change(which I do not want): http://img822.imageshack.us/img822/9073/wrongwaytoscale.png 3.This is how the correct scaling should look like. Appropriate faces gets caled in this case where the scale is on X axis(top, bottom, back): http://imageshack.us/photo/my-images/163/rightwayxscale1.png/ 4.But the scale factor might not be the same for all object all of the times. In this case the back has to get scaled a bit more or it leaves gaps: http://imageshack.us/photo/my-images/9/problemwhenscaling.png/ 5.If everything goes well this is how the final object should look like: http://imageshack.us/photo/my-images/856/rightwayxscale2.png/ So, as you have might noticed there are quite a bit of things to look out when scaling. I am asking you, if any of you have any idea on how to accomplish this scaling. I have tried whole bunch of things, from scaling all of the object by the same scale factor, to subtracting and adding sizes to get the right size. But nothing I tried worked, if one mesh got scaled correctly then others didnt. Donwload the example object. English is not my first language, so I am really sorry if its hard to understand what I am saying.

• Copying Properties between 2 Different Types&hellip;

  - by Shawn Cicoria

  I’m not sure where I had seen some of this base code, but this comes up time & time again on projects. Here’s a little method that copies all the R/W properties (public) between 2 distinct class definitions: It’s called as follows: private static void Test1() { MyClass obj1 = new MyClass() { Prop1 = "one", Prop2 = "two", Prop3 = 100 }; MyOtherClass obj2 = null; obj2 = CopyClass(obj1); Console.WriteLine(obj1); Console.WriteLine(obj2); } namespace Space1 { public class MyClass { public string Prop1 { get; set; } public string Prop2 { get; set; } public int Prop3 { get; set; } public override string ToString() { var rv = string.Format("MyClass: {0} Prop2: {1} Prop3 {2}", Prop1, Prop2, Prop3); return rv; } } } namespace Space2 { public class MyOtherClass { public string Prop1 { get; set; } public string Prop2 { get; set; } public int Prop3 { get; set; } public override string ToString() { var rv = string.Format("MyOtherClass: {0} Prop2: {1} Prop3 {2}", Prop1, Prop2, Prop3); return rv; } } Source of the method: /// /// Provides a Copy of Public fields between 2 distinct classes /// /// Source class name /// Target class name /// Instance of type Source /// An instance of type Target copying all public properties matching name from the Source. public static T CopyClass(S source) where T : new() { T target = default(T); BindingFlags flags = BindingFlags.Public | BindingFlags.Instance; if (source == null) { return (T)target; } if (target == null) target = new T(); PropertyInfo[] objProperties = target.GetType().GetProperties(flags); foreach (PropertyInfo pi in objProperties) { string name = pi.Name; PropertyInfo sourceProp = source.GetType().GetProperty(name, flags); if (sourceProp == null) { throw new ApplicationException(string.Format("CopyClass - object type {0} & {1} mismatch in property:{2}", source.GetType(), target.GetType(), name)); } if (pi.CanWrite && sourceProp.CanRead) { object sourceValue = sourceProp.GetValue(source, null); pi.SetValue(target, sourceValue, null); } else { throw new ApplicationException(string.Format("CopyClass - can't read/write a property object types {0} & {1} property:{2}", source.GetType(), target.GetType(), name)); } } return target; }

• Why distant objects draw in front of close objects?

  - by cad

  I am rendering two cubes in the space using XNA 4.0 and the layering of objects only works from certain angles. Here is what I see from the front angle (everything ok) Here is what I see from behind This is my draw method. Cubes are drawn by serverManager and serverManager1 protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); switch (_gameStateFSM.State) { case GameFSMState.GameStateFSM.INTROSCREEN: spriteBatch.Begin(); introscreen.Draw(spriteBatch); spriteBatch.End(); break; case GameFSMState.GameStateFSM.GAME: spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend); // Text screenMessagesManager.Draw(spriteBatch, firstPersonCamera.cameraPosition, fpsHelper.framesPerSecond); // Camera firstPersonCamera.Draw(); // Servers serverManager.Draw(GraphicsDevice, firstPersonCamera.viewMatrix, firstPersonCamera.projMatrix); serverManager1.Draw(GraphicsDevice, firstPersonCamera.viewMatrix, firstPersonCamera.projMatrix); // Room //roomManager.Draw(GraphicsDevice, firstPersonCamera.viewMatrix); spriteBatch.End(); break; case GameFSMState.GameStateFSM.EXITGAME: break; default: break; } base.Draw(gameTime); fpsHelper.IncrementFrameCounter(); } serverManager and serverManager1 are instances of the same class ServerManager that draws a cube. The draw method for ServerManager is: public void Draw(GraphicsDevice graphicsDevice, Matrix viewMatrix, Matrix projectionMatrix) { cubeEffect.World = Matrix.CreateTranslation(modelPosition); // Set the World matrix which defines the position of the cube cubeEffect.View = viewMatrix; // Set the View matrix which defines the camera and what it's looking at cubeEffect.Projection = projectionMatrix; // Enable textures on the Cube Effect. this is necessary to texture the model cubeEffect.TextureEnabled = true; cubeEffect.Texture = cubeTexture; // Enable some pretty lights cubeEffect.EnableDefaultLighting(); // apply the effect and render the cube foreach (EffectPass pass in cubeEffect.CurrentTechnique.Passes) { pass.Apply(); cubeToDraw.RenderToDevice(graphicsDevice); } } Obviously there is something I am doing wrong. Any hint of where to look? (Maybe z-buffer or occlusion tests?)

• [AJAX Numeric Updown Control] Microsoft JScript runtime error: The number of fractional digits is out of range

  - by Jenson

  If you have using Ajax control toolkits a lot (which I will skip the parts on where to download and how to configure it in Visual Studio 2010), you might have encountered some bugs or limitations of the controls, or rather, some weird behaviours. I would call them weird behaviours though. Recently, I've been working on a Ajax numeric updown control, which i remember clearly it was working fine without problems. In fact, I use 2 numeric updown control this time. So I went on to configure it to be as simple as possible and I will just use the default up and down buttons provided by it (so that I won't need to design my own). I have two textbox controls to display the value controlled by the updown control. One for month, and another for year. <asp:TextBox ID="txtMonth" runat="server" CssClass="txtNumeric" ReadOnly="True" Width="150px" /> <asp:TextBox ID="txtYear" runat="server" CssClass="txtNumeric" ReadOnly="True" Width="150px" /> So I will now drop 1 numeric updown control for each of the textboxes. <asp:NumericUpDownExtender ID="txtMonth_NumericUpDownExtender"     runat="server" TargetControlID="txtMonth" Maximum="12" Minimum="1" Width="152"> </asp:NumericUpDownExtender>                          <asp:NumericUpDownExtender ID="txtYear_NumericUpDownExtender"     runat="server" TargetControlID="txtYear" Width="152"> </asp:NumericUpDownExtender>                                                  You noticed that I configure the Maximum and Minimum value for the first numericupdown control, but I never did the same for the second one (for txtYear). That's because it won't work, well, at least for me. So I remove the Minimum="2000" and Maximum="2099" from there. Then I would configure the initial value to the the current year, and let the year to flow up and down freely. If you want, you want write the codes to restrict it. Here are the codes I used on PageLoad:     Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load         If Not Page.IsPostBack Then             If Trim(txtMonth.Text) = "" Then                 Me.txtMonth.Text = System.DateTime.Today.Month             End If             If Trim(txtYear.Text) = "" Then                 Me.txtYear.Text = System.DateTime.Today.Year             End If         End If     End Sub   Enjoy!

• Threads slowing down application and not working properly

  - by Belgin

  I'm making a software renderer which does per-polygon rasterization using a floating point digital differential analyzer algorithm. My idea was to create two threads for rasterization and have them work like so: one thread draws each even scanline in a polygon and the other thread draws each odd scanline, and they both start working at the same time, but the main application waits for both of them to finish and then pauses them before continuing with other computations. As this is the first time I'm making a threaded application, I'm not sure if the following method for thread synchronization is correct: First of all, I use two global variables to control the two threads, if a global variable is set to 1, that means the thread can start working, otherwise it must not work. This is checked by the thread running an infinite loop and if it detects that the global variable has changed its value, it does its job and then sets the variable back to 0 again. The main program also uses an empty while to check when both variables become 0 after setting them to 1. Second, each thread is assigned a global structure which contains information about the triangle that is about to be rasterized. The structures are filled in by the main program before setting the global variables to 1. My dilemma is that, while this process works under some conditions, it slows down the program considerably, and also it fails to run properly when compiled for Release in Visual Studio, or when compiled with any sort of -O optimization with gcc (i.e. nothing on screen, even SEGFAULTs). The program isn't much faster by default without threads, which you can see for yourself by commenting out the #define THREADS directive, but if I apply optimizations, it becomes much faster (especially with gcc -Ofast -march=native). N.B. It might not compile with gcc because of fscanf_s calls, but you can replace those with the usual fscanf, if you wish to use gcc. Because there is a lot of code, too much for here or pastebin, I created a git repository where you can view it. My questions are: Why does adding these two threads slow down my application? Why doesn't it work when compiling for Release or with optimizations? Can I speed up the application with threads? If so, how? Thanks in advance.

• ODEE Green Field (Windows) Part 2 - WebLogic

  - by AndyL-Oracle

  Welcome back to the next installment on how to install Oracle Documaker Enterprise Edition onto a green field environment! In my previous post, I went over some basic introductory information and we installed the Oracle database. Hopefully you've completed that step successfully, and we're ready to move on - so let's dive in! For this installment, we'll be installing WebLogic 10.3.6, which is a prerequisite for ODEE 12.3 and 12.2. Prior to installing the WebLogic application server, verify that you have met the software prerequisites. Review the documentation – specifically you need to make sure that you have the appropriate JDK installed. There are advisories if you are using JDK 1.7. These instructions assume you are using JDK 1.6, which is available here. The first order of business is to unzip the installation package into a directory location. This procedure should create a single file, wls1036_generic.jar. Navigate to and execute this file by double-clicking it. This should launch the installer. Depending on your User Account Control rights you may need to approve running the setup application. Once the installer application opens, click Next. Select your Middleware Home. This should be within your ORACLE_HOME. The default is probably fine. Click Next. Uncheck the Email option. Click Yes. Click Next. Click Yes Click Yes and Yes again (yes, it’s quite circular). Check that you wish to remain uninformed and click Continue. Click Custom and Next. Uncheck Evaluation Database and Coherence, then click Next. Select the appropriate JDK. This should be a 64-bit JDK if you’re running a 64-bit OS. You may need to browse to locate the appropriate JAVA_HOME location. Check the JDK and click Next. Verify the installation directory and click Next. Click Next. Allow the installation to progress… Uncheck Run Quickstart and click Done.  And that's it! It's all quite painless - so let's proceed on to set up SOA Suite, shall we?

• Automatically change resolution when not in dock

  - by jwir3

  I have Ubuntu 11.04 (yep, I know it's old news) on my Lenovo W520. At home, I have a dock with dual monitors. I have a pretty decent setup - things work almost perfectly (hence the reason I'm reluctant to upgrade... that and I'm not 100% sold on Unity). Anyway, the only annoyance I have is that when I'm on travel, I use the laptop screen. When I un-dock the laptop, I need to manually go into nvidia x-server settings and change the resolution from 'Auto' to 1920x1200, or it will think I have two screens, and my mouse pointer will be able to go way off the left side of the screen. This isn't a big deal, but I need to do it every time I restart the x-server (so if I reboot, or have to kill it, etc...) What would be really nice is if there was a way for it to automatically detect whether or not there is external monitors (which it seems to do already), and switch into the mode I select, depending on which monitors are connected. Is there any way to accomplish this? I've posted my xorg.conf file for reference. # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 270.29 (buildd@allspice) Fri Feb 25 14:42:07 UTC 2011 # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 275.19 ([email protected]) Tue Jul 12 18:35:38 PDT 2011 #Section "Monitor" # Identifier "Monitor1" # VendorName "Lenovo" # ModelName "ThinkpadLCD" # #HorizSync 28.0 - 33.0 # #VertRefresh 43.0 - 72.0 # #Option "DPMS" #EndSection Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "0" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "DELL U2410" HorizSync 30.0 - 81.0 VertRefresh 56.0 - 76.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "Quadro 1000M" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection Section "Screen" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +0+120, DFP-6: nvidia-auto-select +1920+0" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +0+120, DFP-5: nvidia-auto-select +1920+0" # Removed Option "metamodes" "DFP-0: nvidia-auto-select +1920+419, DFP-5: nvidia-auto-select +3840+0, DFP-6: nvidia-auto-select +0+0" # Removed Option "metamodes" "DFP-5: nvidia-auto-select +0+0, DFP-6: 1920x1200 +1920+0" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "NoLogo" "True" Option "TwinViewXineramaInfoOrder" "DFP-0" Option "TwinView" "1" Option "metamodes" "DFP-5: nvidia-auto-select +1920+0, DFP-6: 1920x1200 +0+0" SubSection "Display" Depth 24 EndSubSection EndSection

• Normal Redundancy (Double Mirroring) Option Available

  - by TammyBednar

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif";} The Oracle Database Appliance 2.4 Patch was released last week and provides you an option of ASM normal redundancy (double mirroring) during the initial deployment of the Database Appliance. The default deployment of the Oracle Database Appliance is high redundancy for the +DATA and +RECO disk groups. While there is 12TB of raw shared storage available, the Database Backup Location and Disk Group Redundancy govern how much usable storage is presented after the initial deployment is completed. The Database Backup Location options are Local or External. When the Local Backup Option is selected, this means that 60% of the available shared storage will be allocated for the Fast Recovery Area that contains database backups and archive logs. The External Backup Option will allocate 20% of the available shared storage to the Fast Recovery Area. So, let’s look at an example of High Redundancy and External Backups. Disk Group Redundancy – High --> Triple Mirroring to provide ~4TB of available storage Database Backup Location – External --> 20% of available shared storage allocated to +RECO +DATA = 3.2TB of usable storage, +RECO = 0.8TB of usable storage What about Normal Redundancy with External Backups? Disk Group Redundancy – Normal --> Double Mirroring to provide ~6TB of available storage Database Backup Location – External --> 20% of available shared storage allocated to +RECO +DATA = 4.8TB of usable storage, +RECO = 1.2TB of usable storage As a best practice, we would recommend using Normal Redundancy for your test and/or development Oracle Database Appliances and High Redundancy for production.

• Development Approach: User Interface In or Domain Model Out?

  - by Berin Loritsch

  While I've never delivered anything using Smalltalk, my brief time playing with it has definitely left its mark. The only way to describe the experience is MVC the way it was meant to be. Essentially, all the heavy lifting for your application is done in the business objects (or domain model if you are so inclined). The standard controls are bound to the business objects in some way. For example, a text box is mapped to an object's field (the field itself is an object so it's easy to do). A button would mapped to a method. This is all done with a very simple and natural API. We don't have to think about binding objects, etc. It just works. Yet, in many newer languages and APIs you are forced to think from the outside in. First with C++ and MFC, and now with C# and WPF, Microsoft has gotten it's developer world hooked on GUI builders where you build your application by implementing event handlers. Java Swing development isn't so different, only you are writing the code to instantiate the controls on the form yourself. For some projects, there may never even be a domain model--just event handlers. I've been in and around this model for most of my carreer. Each way forces you to think differently. With the Smalltalk approach, your domain is smart while your GUI is dumb. With the default VisualStudio approach, your GUI is smart while your domain model (if it exists) is rather anemic. Many developers that I work with see value in the Smalltalk approach, and try to shoehorn that approach into the VisualStudio environment. WPF has some dynamic binding features that makes it possible; but there are limitations. Inevitably some code that belongs in the domain model ends up in the GUI classes. So, which way do you design/develop your code? Why? GUI first. User interaction is paramount. Domain first. I need to make sure the system is correct before we put a UI on it. There's pros and cons for either approach. Domain model fits in there with crystal cathedrals and pie in the sky. GUI fits in there with quick and dirty (sometimes really dirty). And for an added bonus: How do you make sure the code is maintainable?

• 12.04 Booting into Terminal

  - by user170796

  To preface this, I would like to say that I am completely new to Ubuntu and have essentially zero programming experience/experience working with command line and terminal. I installed Ubuntu because I would like to get into programming. If you could provide me with the simplest instructions possible, I would be grateful. I have a Lenovo Ideapad Y500 (Intel i7, NVidia GT 750m, 1TB HDD, 16GB SSD cache, 8GB RAM) with Windows 8 on it. Using a Live CD, I installed Ubuntu 12.04 onto a 75 GB partition. During the installation, I kept all default settings except for one thing; I decided to encrypt my home folder, and so checked the corresponding box. The installation completed, and I restarted. Once I restarted, I saw the options "Ubuntu, with Linux 3.2.0-23-generic" "Ubuntu, with Linux 3.2.0-23-generic (recovery mode)" "Memory test (memtest86+)" "Memory test (memtest86+, serial console 115200)" "Windows Recovery Environment (loader) (on /dev/sdb3)" "Windows 8 (loader) (on /dev/sdb5)" "System Setup" I chose the first option, and was directed to a screen with the Ubuntu logo and the row of five dots below that change from orange to white. Then, I was brought to a full screen terminal that prompted me to login, which I did. I saw no option to boot into GUI at all, and am lost. I've been searching around and have tried the "startx" command to no avail. Should the command have some sort of context or something? I've also tried selecting the recovery mode option from the boot manager. I've tried the resume option from the following menu, which eventually just shuts down the computer after displaying a lot of scrolling text that's too fast for me to read. I've also tried the failsafex mode from the recovery mode menu, which only brings up a terminal box at the bottom of the window that covers the entire bottom part of the screen. Commands won't work in this window. When I try to access Windows 8, I get a message saying that the EFI file path was not specified or something along those lines. I had to enable Secure Boot in order to access Windows 8 (I had disabled it to be able to boot from the Live CD), which is functioning normally. I am at a complete loss for what to do. Any help will be extremely appreciated. EDIT: Bonus question! If you could figure out a way for me to boot to Windows 8 without having to enable Secure Boot, it would save me a lot of trouble. I can deal with switching every time, but I'd rather not have to.

• Protobuf design patterns

  - by Monster Truck

  I am evaluating Google Protocol Buffers for a Java based service (but am expecting language agnostic patterns). I have two questions: The first is a broad general question: What patterns are we seeing people use? Said patterns being related to class organization (e.g., messages per .proto file, packaging, and distribution) and message definition (e.g., repeated fields vs. repeated encapsulated fields*) etc. There is very little information of this sort on the Google Protobuf Help pages and public blogs while there is a ton of information for established protocols such as XML. I also have specific questions over the following two different patterns: Represent messages in .proto files, package them as a separate jar, and ship it to target consumers of the service --which is basically the default approach I guess. Do the same but also include hand crafted wrappers (not sub-classes!) around each message that implement a contract supporting at least these two methods (T is the wrapper class, V is the message class (using generics but simplified syntax for brevity): public V toProtobufMessage() { V.Builder builder = V.newBuilder(); for (Item item : getItemList()) { builder.addItem(item); } return builder.setAmountPayable(getAmountPayable()). setShippingAddress(getShippingAddress()). build(); } public static T fromProtobufMessage(V message_) { return new T(message_.getShippingAddress(), message_.getItemList(), message_.getAmountPayable()); } One advantage I see with (2) is that I can hide away the complexities introduced by V.newBuilder().addField().build() and add some meaningful methods such as isOpenForTrade() or isAddressInFreeDeliveryZone() etc. in my wrappers. The second advantage I see with (2) is that my clients deal with immutable objects (something I can enforce in the wrapper class). One disadvantage I see with (2) is that I duplicate code and have to sync up my wrapper classes with .proto files. Does anyone have better techniques or further critiques on any of the two approaches? *By encapsulating a repeated field I mean messages such as this one: message ItemList { repeated item = 1; } message CustomerInvoice { required ShippingAddress address = 1; required ItemList = 2; required double amountPayable = 3; } instead of messages such as this one: message CustomerInvoice { required ShippingAddress address = 1; repeated Item item = 2; required double amountPayable = 3; } I like the latter but am happy to hear arguments against it.

• PMDB Block Size Choice

  - by Brian Diehl

  Choosing a block size for the P6 PMDB database is not a difficult task. In fact, taking the default of 8k is going to be just fine. Block size is one of those things that is always hotly debated. Everyone has their personal preference and can sight plenty of good reasons for their choice. To add to the confusion, Oracle supports multiple block sizes withing the same instance. So how to decide and what is the justification? Like most OLTP systems, Oracle Primavera P6 has a wide variety of data. A typical table's average row size may be less than 50 bytes or upwards of 500 bytes. There are also several tables with BLOB types but the LOB data tends not to be very large. It is likely that no single block size would be perfect for every table. So how to choose? My preference is for the 8k (8192 bytes) block size. It is a good compromise that is not too small for the wider rows, yet not to big for the thin rows. It is also important to remember that database blocks are the smallest unit of change and caching. I prefer to have more, individual "working units" in my database. For an instance with 4gb of buffer cache, an 8k block will provide 524,288 blocks of cache. The following SQL*Plus script returns the average, median, min, and max rows per block. column "AVG(CNT)" format 999.99 set verify off select avg(cnt), median(cnt), min(cnt), max(cnt), count(*) from ( select dbms_rowid.ROWID_RELATIVE_FNO(rowid) , dbms_rowid.ROWID_BLOCK_NUMBER(rowid) , count(*) cnt from &tab group by dbms_rowid.ROWID_RELATIVE_FNO(rowid) , dbms_rowid.ROWID_BLOCK_NUMBER(rowid) ) Running this for the TASK table, I get this result on a database with an 8k block size. Each activity, on average, has about 19 rows per block. Enter value for tab: task AVG(CNT) MEDIAN(CNT) MIN(CNT) MAX(CNT) COUNT(*) -------- ----------- ---------- ---------- ---------- 18.72 19 3 28 415917 I recommend an 8k block size for the P6 transactional database. All of our internal performance and scalability test are done with this block size. This does not mean that other block sizes will not work. Instead, like many other parameters, this is the safest choice.

• Architecture or Pattern for handling properties with custom setter/getter?

  - by Shelby115

  Current Situation: I'm doing a simple MVC site for keeping journals as a personal project. My concern is I'm trying to keep the interaction between the pages and the classes simplistic. Where I run into issues is the password field. My setter encrypts the password, so the getter retrieves the encrypted password. public class JournalBook { private IEncryptor _encryptor { get; set; } private String _password { get; set; } public Int32 id { get; set; } public String name { get; set; } public String description { get; set; } public String password { get { return this._password; } set { this.setPassword(this._password, value, value); } } public List<Journal> journals { get; set; } public DateTime created { get; set; } public DateTime lastModified { get; set; } public Boolean passwordProtected { get { return this.password != null && this.password != String.Empty; } } ... } I'm currently using model-binding to submit changes or create new JournalBooks (like below). The problem arises that in the code below book.password is always null, I'm pretty sure this is because of the custom setter. [HttpPost] public ActionResult Create(JournalBook book) { // Create the JournalBook if not null. if (book != null) this.JournalBooks.Add(book); return RedirectToAction("Index"); } Question(s): Should I be handling this not in the property's getter/setter? Is there a pattern or architecture that allows for model-binding or another simple method when properties need to have custom getters/setters to manipulate the data? To summarize, how can I handle the password storing with encryption such that I have the following, Robust architecture I don't store the password as plaintext. Submitting a new or modified JournalBook is as easy as default model-binding (or close to it).

• JEditorPane Code Completion (Part 2)

  - by Geertjan

  Figured it out! No need to create a fake Java file, unlike what I said in part 1, no need to depend on all the Java Editor modules, if you use DialogBinding.bindComponentToDocument, instead of DialogBinding.bindComponentToFile: public final class CountryEditorTopComponent extends TopComponent {     public CountryEditorTopComponent() {         initComponents();         setName(Bundle.CTL_CountryEditorTopComponent());         setToolTipText(Bundle.HINT_CountryEditorTopComponent());         EditorKit kit = CloneableEditorSupport.getEditorKit("text/plain");         jEditorPane1.setEditorKit(kit);         DialogBinding.bindComponentToDocument(jEditorPane1.getDocument(), 0, 0, jEditorPane1);         jEditorPane1.setText("Egypt");     } The above requires a dependency on Editor Library 2, which is where DialogBinding is found. Aside from that, you need all the dependencies required by the Code Completion API, as described in the Code Completion tutorial on the NetBeans Platform Learning Trail. Once you've done that, go to the Project Properties dialog of the application and then in the "ide" cluster, include "Plain Editor" and "Plain Editor Library". I.e., two additional JARs only. These two are needed because you've set the MIME type to "text/plain", which is needed because DialogBinding expects the JEditorPane to have a MIME type. And now everything works. Press Ctrl-Space in your JEditorPane and, because your CompletionProvider is registered in "text/x-dialog-binding" (via the annotation on CompletionProvider), your completion items are displayed. (The only MIME type for binding a document to a component, by default, is "text/x-dialog-binding", which means the next step is for someone to figure out how to support multiple different of such MIME types, since each JEditorPane in your application is likely to require its own specific code completion support.) I think this is a really workable solution for real scenarios where JEditorPanes in NetBeans Platform applications require code completion.
