• Difficulties with rotation of a sprite

  - by Johnny

  I want to program a dolphin that jumps and rotates like a real dolphin. Jumping is not the problem, but I don't know how to make the rotation. At the moment, my dolphin rotates a little weird. But I want that it rotates like a real dolphin does. How can I improve the rotation? public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Texture2D image, water; float Gravity = 5.0F; float Acceleration = 20.0F; Vector2 Position = new Vector2(1200,720); Vector2 Velocity; float rotation = 0; SpriteEffects flip; Vector2 Speed = new Vector2(0, 0); public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; graphics.PreferredBackBufferWidth = 1280; graphics.PreferredBackBufferHeight = 720; } protected override void Initialize() { base.Initialize(); } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); image = Content.Load<Texture2D>("cartoondolphin"); water = Content.Load<Texture2D>("background"); flip = SpriteEffects.None; } protected override void Update(GameTime gameTime) { float VelocityX = 0f; float VelocityY = 0f; float time = (float)gameTime.ElapsedGameTime.TotalSeconds; KeyboardState kbState = Keyboard.GetState(); if(kbState.IsKeyDown(Keys.Left)) { rotation = 0; flip = SpriteEffects.None; VelocityX += -5f; } if(kbState.IsKeyDown(Keys.Right)) { rotation = 0; flip = SpriteEffects.FlipHorizontally; VelocityX += 5f; } // jump if the dolphin is under water if(Position.Y >= 670) { if (kbState.IsKeyDown(Keys.A)) { if (flip == SpriteEffects.None) { rotation += 0.01f; VelocityY += 40f; } else { rotation -= 0.01f; VelocityY += 40f; } } } else { if (flip == SpriteEffects.None) { rotation -= 0.01f; VelocityY += -10f; } else { rotation += 0.01f; VelocityY += -10f; } } float deltaY = 0; float deltaX = 0; deltaY = Gravity * (float)gameTime.ElapsedGameTime.TotalSeconds; deltaX += VelocityX * (float)gameTime.ElapsedGameTime.TotalSeconds * Acceleration; deltaY += -VelocityY * (float)gameTime.ElapsedGameTime.TotalSeconds * Acceleration; Speed = new Vector2(Speed.X + deltaX, Speed.Y + deltaY); Position += Speed * (float)gameTime.ElapsedGameTime.TotalSeconds; Velocity.X = 0; if (Position.Y + image.Height/2 > graphics.PreferredBackBufferHeight) Position.Y = graphics.PreferredBackBufferHeight - image.Height/2; base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(water, new Rectangle(0, graphics.PreferredBackBufferHeight -100, graphics.PreferredBackBufferWidth, 100), Color.White); spriteBatch.Draw(image, Position, null, Color.White, rotation, new Vector2(image.Width / 2, image.Height / 2), 1, flip, 1); spriteBatch.End(); base.Draw(gameTime); } }

Microsoft has agreed to acquire Yammer for 1.2 billion. Personally, I believe that Yammer’s amazing success can be mainly attributed to their wise decision to use Berkeley DB Java Edition as their backend data store. :-) I’m only kidding, of course. However, as Ryan Kennedy points out in the video I recently blogged about, BDB JE did provide the right feature set that allowed them to reliably grow their business. Which in turn allowed them to focus on their core value add. As it turns out, their ‘add’ is quite valuable! This actually makes sense to me, a lot more sense than certain other recent social acquisitions, and here’s why. Last year, IDC declared that we are entering a new computing era, the era of the “3rd Platform.” In case you’re curious, the first 2 were terminal computing and client/server computing, IIRC. Anyway, this 3rd one is more complicated. This year, IDC refined the concept further. It now involves 4 distinct buzzwords: cloud, social, mobile, and big data. Yammer is a social media platform that runs in the cloud, designed to be used from mobile devices. Their approach, using Berkeley DB Java Edition with High Availability, qualifies as big data. This means that Yammer is sitting right smack in the center if IDC’s new computing era. Another way to put it is: the folks at Yammer were prescient enough to predict where things were headed, and get there first. They chose Berkeley DB to handle their data. Maybe you should too!

• Encode two integers into colour values and compare them in a HLSL shader

  - by Ben Slinger

  I am writing a 2D point and click adventure game in Monogame, and I'd like to be able to create an image mask for every room which defines which parts of the background a character can walk behind, and at which Y value a character needs to be at for the background to be drawn above the character. I haven't done any shader work before but after doing some reading I thought the following solution should work: Create a mask for the room with different walk behind areas painted in a colour that defines the baseline Y value (Walk Behind Mask) Render all objects to a RenderTarget2D (Base Texture) Render all objects to a different RenderTarget2D, but changing every pixel of each object to a colour that defines its Y value (Position Mask) Pass these two textures plus the image mask into the shader, and for each pixel compare the colour of the image mask to the colour of the Position Mask to the Walk Behind Mask - if the Position Mask pixel is larger (thus lower on the screen and closer to the camera) than the Walk Behind Mask, draw the pixel from the Base Texture, otherwise draw a transparent pixel (allowing the background to show through). I've got it mostly working, but I'm having trouble packing and unpacking the Y values into colours and retrieving them correctly in the shader. Here are some code examples of how I'm doing it so far: (When drawing to the Position Mask RenderTarget2D) Color posColor = new Color(((int)Position.Y >> 16) & 255, ((int)Position.Y >> 8) & 255, (int)Position.Y & 255); So as far as I can tell, this should be taking the first 3 bytes of the position integer and encoding them into a 4 byte colour (ignoring the alpha as the 4th byte). This seems to work fine, as when my character is at Y = 600, the resulting Color from this is: {[Color: R=0, G=2, B=88, A=255, PackedValue=4283957760]}. I then have an area in my Walk Behind Mask that I only want the character to be displayed behind if his Y value is lower than 655, so I've painted it with R=0, G=2, B=143, A=255. Now, I think I have the shader OK as well, here's what I have: sampler BaseTexture : register(s0); sampler MaskTexture : register(s1); sampler PositionTexture : register(s2); float4 mask( float2 coords : TEXCOORD0 ) : COLOR0 { float4 color = tex2D(BaseTexture, coords); float4 maskColor = tex2D(MaskTexture, coords); float4 positionColor = tex2D(PositionTexture, coords); float maskCompare = (maskColor.r * pow(2,24)) + (maskColor.g * pow(2,16)) + (maskColor.b * pow(2,8)); float positionCompare = (positionColor.r * pow(2,24)) + (positionColor.g * pow(2,16)) + (positionColor.b * pow(2,8)); return positionCompare < maskCompare ? float4(0,0,0,0) : color; } technique Technique1 { pass NoEffect { PixelShader = compile ps_3_0 mask(); } } This isn't working, however - currently all characters are displayed behind the walk behind area, regardless of their Y value. I tried printing out some debug info by grabbing the pixel from both the Position Mask and the Walk Under Mask under the current mouse position, and it seems like maybe the colours aren't being rendered to the Position Mask correctly? When calculating the colour in that code above I'm getting R=0, G=2, B=88, A=255, but when I mouseover my character I get R=0, G=0, B=30, A=255. Any ideas what I'm doing wrong? It seems like maybe I'm losing some information when rendering to the RenderTarget2D, but I'm now knowledgeable enough to figure out what's happening. Also, I should probably ask, is this an efficient way to do this? Will there be a performance impact? Edit: Whoops, turns out there was a bug that I'd introduced myself, I was drawing out the Position Mask with the position Color, left over from some early testing I was doing. So this solution is working perfectly, though I'm still interested in whether this is an efficient solution performance wise.

• Sprite animation in openGL - Some frames are being skipped

  - by Sid

  Earlier, I was facing problems on implementing sprite animation in openGL ES. Now its being sorted up. But the problem that i am facing now is that some of my frames are being skipped when a bullet(a circle) strikes on it. What I need : A sprite animation should stop at the last frame without skipping any frame. What I did : Collision Detection function and working properly. PS : Everything is working fine but i want to implement the animation in OPENGL ONLY. Canvas won't work in my case. ------------------------ EDIT----------------------- My sprite sheet. Consider the animation from Left to right and then from top to bottom Here is an image for a better understanding. My spritesheet ... class FragileSquare{ FloatBuffer fVertexBuffer, mTextureBuffer; ByteBuffer mColorBuff; ByteBuffer mIndexBuff; int[] textures = new int[1]; public boolean beingHitFromBall = false; int numberSprites = 20; int columnInt = 4; //number of columns as int float columnFloat = 4.0f; //number of columns as float float rowFloat = 5.0f; int oldIdx; public FragileSquare() { // TODO Auto-generated constructor stub float vertices [] = {-1.0f,1.0f, //byte index 0 1.0f, 1.0f, //byte index 1 //byte index 2 -1.0f, -1.0f, 1.0f,-1.0f}; //byte index 3 float textureCoord[] = { 0.0f,0.0f, 0.25f,0.0f, 0.0f,0.20f, 0.25f,0.20f }; byte indices[] = {0, 1, 2, 1, 2, 3 }; ByteBuffer byteBuffer = ByteBuffer.allocateDirect(4*2 * 4); // 4 vertices, 2 co-ordinates(x,y) 4 for converting in float byteBuffer.order(ByteOrder.nativeOrder()); fVertexBuffer = byteBuffer.asFloatBuffer(); fVertexBuffer.put(vertices); fVertexBuffer.position(0); ByteBuffer byteBuffer2 = ByteBuffer.allocateDirect(textureCoord.length * 4); byteBuffer2.order(ByteOrder.nativeOrder()); mTextureBuffer = byteBuffer2.asFloatBuffer(); mTextureBuffer.put(textureCoord); mTextureBuffer.position(0); } public void draw(GL10 gl){ gl.glFrontFace(GL11.GL_CW); gl.glEnableClientState(GL10.GL_VERTEX_ARRAY); gl.glVertexPointer(1,GL10.GL_FLOAT, 0, fVertexBuffer); gl.glEnable(GL10.GL_TEXTURE_2D); if(MyRender.flag2==1){ /** Collision has taken place*/ int idx = oldIdx==(numberSprites-1) ?

• How to Add Your Gmail Account to Outlook 2013 Using IMAP

  - by Lori Kaufman

  If you use Outlook to check and manage your email, you can easily use it to check your Gmail account as well. You can setup your Gmail account to allow you to synchronize email across multiple machines using email clients instead of a browser. We will show you how to use IMAP in your Gmail account so you can synchronize your Gmail account across multiple machines, and then how to add your Gmail account to Outlook 2013. To setup your Gmail account to use IMAP, sign in to your Gmail account and go to Mail. Click the Settings button in the upper, right corner of the window and select Settings from the drop-down menu. On the Settings screen, click Forwarding and POP/IMAP. Scroll down to the IMAP Access section and select Enable IMAP. Click Save Changes at the bottom of the screen. Close your browser and open Outlook. To begin adding your Gmail account, click the File tab. On the Account Information screen, click Add Account. On the Add Account dialog box, you can choose the E-mail Account option which automatically sets up your Gmail account in Outlook. To do this enter your name, email address, and the password for your Gmail account twice. Click Next. The progress of the setup displays. The automatic process may or may not work. If the automatic process fails, select Manual setup or additional server types, instead of E-mail Account, and click Next. On the Choose Service screen, select POP or IMAP and click Next. On the POP and IMAP Account Settings enter the User, Server, and Logon Information. For the Server Information, select IMAP from the Account Type drop-down list and enter the following for the incoming and outgoing server information: Incoming mail server: imap.googlemail.com Outgoing mail server (SMTP): smtp.googlemail.com Make sure you enter your full email address for the User Name and select Remember password if you want Outlook to automatically log you in when checking email. Click More Settings. On the Internet E-mail Settings dialog box, click the Outgoing Server tab. Select the My outgoing server (SMTP) requires authentication and make sure the Use same settings as my incoming mail server option is selected. While still in the Internet E-mail Settings dialog box, click the Advanced tab. Enter the following information: Incoming server: 993 Incoming server encrypted connection: SSL Outgoing server encrypted connection TLS Outgoing server: 587 NOTE: You need to select the type of encrypted connection for the outgoing server before entering 587 for the Outgoing server (SMTP) port number. If you enter the port number first, the port number will revert back to port 25 when you change the type of encrypted connection. Click OK to accept your changes and close the Internet E-mail Settings dialog box. Click Next. Outlook tests the accounts settings by logging into the incoming mail server and sending a test email message. When the test is finished, click Close. You should see a screen saying “You’re all set!”. Click Finish. Your Gmail address displays in the account list on the left with any other email addresses you have added to Outlook. Click the Inbox to see what’s in your Inbox in your Gmail account. Because you’re using IMAP in your Gmail account and you used IMAP to add the account to Outlook, the messages and folders in Outlook reflect what’s in your Gmail account. Any changes you make to folders and any time you move email messages among folders in Outlook, the same changes are made in your Gmail account, as you will see when you log into your Gmail account in a browser. This works the other way as well. Any changes you make to the structure of your account (folders, etc.) in a browser will be reflected the next time you log into your Gmail account in Outlook.

• Old School Wizardry Tip: Batch File Comments

  - by jkauffman

  Johnny, the Endangered Keyboard-Driven Windows User Some of my proudest, obscure Windows tricks are losing their relevance. I know I’m not alone. Keyboard shortcuts are going the way of the dodo. I used to induce fearful awe by slapping Ctrl+Shift+Esc in front of the lowly, pedestrian Windows users. No windows key on the keyboard? No problem: Ctrl+Esc. No menu key on the keyboard: Shift+F10. I am also firmly planted in the habit of closing windows with the Alt+Space menu (Alt+Space, C); and I harbor a brooding, slow=growing list of programs that fail to support this correctly (that means you, Paint.NET). Every time a new version of windows comes out, the support for some of these minor time-saving habits get pared out. Will I complain publicly? Nope, I know my old ways should be axed to conserve precious design energy. In fact, I disapprove of fierce un-intuitiveness for the sake of alleged productivity. Like vim, for example. If you approach a program after being away for 5 years, having to recall encyclopedic knowledge is a flaw. The RTFM disciples have lost. Anyway, some of the items in my arsenal of goofy time-saving tricks are still relevant today. I wanted to draw attention to one that’s stood the test of time. Remember Batch Files? Yes, it’s true, batch files are fading faster than the world of print. But they're not dead yet. I still run into some situations where I opt to use batch files. They are still relevant for build processes, or just various development workflow tools. Sure, there’s powershell, but there’s that stupid Set-ExecutionPolicy speed bump standing in your way; can you really spare the time to A) hunt down that setting on all machines affected and/or B) make futile efforts to convince your coworkers/boss that the hassle was worth it? When possible, I prefer the batch file wild card. And whenever I return to batch files, I end up researching some of the unintuitive aspects such as parameters, quote handling, and ERRORLEVEL. But I never have to remember to use “REM” for comment lines, because there’s a cleaner way to do them! Double Colon For Eye-Friendly Comments Here is a very simple batch file, with pretty much minimal content: @ECHO OFF SETLOCAL REM This is a comment ECHO This batch file doesn’t do much If you code on a daily basis, this may be more suitable to your eyes: @ECHO OFF SETLOCAL :: This is a comment ECHO This batch file doesn’t do much Works great! I imagine I find it preferable due to the similarity to comments in other situations: // or ;  or # I’ve often make visual pseudo-line breaks in my code, and this colon-based syntax works wonders: @ECHO OFF SETLOCAL :: Do stuff ECHO Doing Stuff :::::::::::::::::::::::::::: :: Do more stuff ECHO This batch file doesn’t do much Not only is it more readable, but there’s a slight performance benefit. The batch file engine sees this as an invalid line label and immediately reads the following line. Use that fact to your advantage if this trick leads you into heated nerd debate. Two Pitfalls to Avoid Be aware of that there are a couple situations where this hack will fail you. It most likely won’t be a problem unless you’re getting really sophisticated with your batch files. Pitfall #1: Inline comments @ECHO OFF SETLOCAL IF EXIST C:\SomeFile.txt GOTO END ::This will fail :END Unfortunately, this fails. You can only have whitespace to the left of your comments. Pitfall #2: Code Blocks @ECHO OFF SETLOCAL IF EXIST C:\SomeFile.txt (         :: This will fail         ECHO HELLO ) Code blocks, such as if statements and for loops, cannot contain these comments. This is ultimately due to the fact that entire code blocks are processed as a single line. I originally learned this from Rob van der Woude’s site. He goes into more depth about the behavior of the pitfalls as well, if you are interested in further details. I hope this trick earns you serious geek rep!

• Help me get my 3D camera to look like the ones in RTS

  - by rFactor

  I am a newbie in 3D game development and I am trying to make a real-time strategy game. I am struggling with the camera currently as I am unable to make it look like they do in RTS games. Here is my Camera.cs class using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Input; namespace BB { public class Camera : Microsoft.Xna.Framework.GameComponent { public Matrix view; public Matrix projection; protected Game game; KeyboardState currentKeyboardState; Vector3 cameraPosition = new Vector3(600.0f, 0.0f, 600.0f); Vector3 cameraForward = new Vector3(0, -0.4472136f, -0.8944272f); BoundingFrustum cameraFrustum = new BoundingFrustum(Matrix.Identity); // Light direction Vector3 lightDir = new Vector3(-0.3333333f, 0.6666667f, 0.6666667f); public Camera(Game game) : base(game) { this.game = game; } public override void Initialize() { this.view = Matrix.CreateLookAt(this.cameraPosition, this.cameraPosition + this.cameraForward, Vector3.Up); this.projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver4, this.game.renderer.aspectRatio, 1, 10000); base.Initialize(); } /* Handles the user input * @ param GameTime gameTime */ private void HandleInput(GameTime gameTime) { float time = (float)gameTime.ElapsedGameTime.TotalMilliseconds; currentKeyboardState = Keyboard.GetState(); } void UpdateCamera(GameTime gameTime) { float time = (float)gameTime.ElapsedGameTime.TotalMilliseconds; // Check for input to rotate the camera. float pitch = 0.0f; float turn = 0.0f; if (currentKeyboardState.IsKeyDown(Keys.Up)) pitch += time * 0.001f; if (currentKeyboardState.IsKeyDown(Keys.Down)) pitch -= time * 0.001f; if (currentKeyboardState.IsKeyDown(Keys.Left)) turn += time * 0.001f; if (currentKeyboardState.IsKeyDown(Keys.Right)) turn -= time * 0.001f; Vector3 cameraRight = Vector3.Cross(Vector3.Up, cameraForward); Vector3 flatFront = Vector3.Cross(cameraRight, Vector3.Up); Matrix pitchMatrix = Matrix.CreateFromAxisAngle(cameraRight, pitch); Matrix turnMatrix = Matrix.CreateFromAxisAngle(Vector3.Up, turn); Vector3 tiltedFront = Vector3.TransformNormal(cameraForward, pitchMatrix * turnMatrix); // Check angle so we cant flip over if (Vector3.Dot(tiltedFront, flatFront) > 0.001f) { cameraForward = Vector3.Normalize(tiltedFront); } // Check for input to move the camera around. if (currentKeyboardState.IsKeyDown(Keys.W)) cameraPosition += cameraForward * time * 0.4f; if (currentKeyboardState.IsKeyDown(Keys.S)) cameraPosition -= cameraForward * time * 0.4f; if (currentKeyboardState.IsKeyDown(Keys.A)) cameraPosition += cameraRight * time * 0.4f; if (currentKeyboardState.IsKeyDown(Keys.D)) cameraPosition -= cameraRight * time * 0.4f; if (currentKeyboardState.IsKeyDown(Keys.R)) { cameraPosition = new Vector3(0, 50, 50); cameraForward = new Vector3(0, 0, -1); } cameraForward.Normalize(); // Create the new view matrix view = Matrix.CreateLookAt(cameraPosition, cameraPosition + cameraForward, Vector3.Up); // Set the new frustum value cameraFrustum.Matrix = view * projection; } public override void Update(Microsoft.Xna.Framework.GameTime gameTime) { HandleInput(gameTime); UpdateCamera(gameTime); } } } The problem is that the initial view is looking in a horizontal direction. I would like to have an RTS like top down view (but with a slight pitch). Can you help me out?

• jqGrid - customizing the multi-select option (restrict single selection and adding custom events)

  - by Renso

  Goal: Using the jgGrid to enable a selection of a checkbox for row selection - which is easy to set in the jqGrid - but also only allowing a single row to be selectable at a time while adding events based on whether the row was selected or de-selected. Environment: jQuery 1.4.4 jqGrid 3.4.4a Issue: The jqGrid does not support the option to restrict the multi-select to only allow for a single selection. You may ask, why bother with the multi-select checkbox function if you only want to allow for the selection of a single row? Good question, as an example, you want to reserve the selection of a row to trigger another kind of event and use the checkbox multi-select to handle a different kind of event; in other words, when I select the row I want something entirely different to happen than when I select to check off the checkbox for that row. Also the setSelection method of the jqGrid is a toggle and has no support for determining whether the checkbox has already been selected or not, So it will simply act as a switch - which it is designed to do - but with no way out of the box to only check off the box (as in not to de-select) rather than act like a switch. Furthermore, the getGridParam('selrow') does not indicate if the row was selected or de-selected, which seems a bit strange and is the main reason for this blog post. Solution: How this will act: When you check off a multi-select checkbox in the gird, and then commence to select another row by checking off that row's multi-select checkbox - I'm not talking there about clicking on the row but using the grid's multi-select checkbox - it will de-select the previous selection so that you are always left with only a single selection. Furthermore, once you select or de-select a multi-select checkbox, fire off an event that will be determined by whether or not the row was selected or de-selected, not just merely clicked on. So if I de-select the row do one thing but when selecting it do another. Implementation (this of course is only a partial code snippet):             multiselect: true,             multiboxonly: true,             onSelectRow: function (rowId) {                 var gridSelRow = $(item).getGridParam('selrow');                 var s;                 s = $(item).getGridParam('selarrrow');                 if (!s || !s[0]) {                     $(item).resetSelection();                     $('#productLineDetails').fadeOut();                     lastsel = null;                     return;                 }                 var selected = $.inArray(rowId, s) != -1;                 if (selected) {                     $('#productLineDetails').show();                 }                 else {                     $('#productLineDetails').fadeOut();                 }                 if (rowId && rowId !== lastsel && selected) {                     $(item).GridToForm(gridSelRow, '#productLineDetails');                     if (lastsel) $(item).setSelection(lastsel, false);                 }                 lastsel = rowId;             }, In the example code above: The "item" property is the id of the jqGrid. The following to settings ensure that the jqGrid will add the new column to select rows with a checkbox and also the not allow for the selection by clicking on the row but to force the user to have to click on the multi-select checkbox to select the row: multiselect: true, multiboxonly: true, Unfortunately the var gridSelRow = $(item).getGridParam('selrow') function will only return the row the user clicked on or rather that the row's checkbox was clicked on and NOT whether or not it was selected nor de-selected, but it retrieves the row id, which is what we will need. The following piece get's all rows that have been selected so far, as in have a checked off multi-select checkbox: var s; s = $(item).getGridParam('selarrrow'); Now determine if the checkbox the user just clicked on was selected or de-selected: var selected = $.inArray(rowId, s) != -1; If it was selected then show a container "#productLineDetails", if not hide that container away. The following instruction populates a form with the grid data using the built-in GridToForm method (just mentioned here as an example) ONLY if the row has been selected and NOT de-selected but more importantly to de-select any other multi-select checkbox that may have been selected: if (rowId && rowId !== lastsel && selected) {                     $(item).GridToForm(gridSelRow, '#productLineDetails');                     if (lastsel) $(item).setSelection(lastsel, false); }

• Enterprise Integration: Can Companies Afford It?

  - by Ralph Wheaton

  Each year, my company holds a global sales conference where employees and partners from around the world some together to collaborate, share knowledge and ideas and learn about future plans.  As a member of the professional services division, several of us had been asked to make a presentation, an elevator pitch in 3 minutes or less that relates to a success we have worked on or directly relates to our tag (that is, our primary technology focus).  Mine happens to be Enterprise Integration as it relates Business Intelligence.  I found it rather difficult to present that pitch in a short amount of time and had to pare it down.  At any rate, in just a little over 3 minutes, this is the presentation I submitted.  Here is a link to the full presentation video in WMV format.   Many companies today subscribe to a buy versus build mentality in an attempt to drive down costs and improve time to implementation. Sometimes this makes sense, especially as it relates to specialized software or software that performs a small number of tasks extremely well. However, if not carefully considered or planned out, this oftentimes leads to multiple disparate systems with silos of data or multiple versions of the same data. For instance, client data (contact information, addresses, phone numbers, opportunities, sales) stored in your CRM system may not play well with Accounts Receivables. Employee data may be stored across multiple systems such as HR, Time Entry and Payroll. Other data (such as member data) may not originate internally, but be provided by multiple outside sources in multiple formats. And to top it all off, some data may have to be manually entered into multiple systems to keep it all synchronized. When left to grow out of control like this, overall performance is lacking, stability is questionable and maintenance is frequent and costly. Worse yet, in many cases, this topology, this hodgepodge of data creates a reporting nightmare. Decision makers are forced to try to put together pieces of the puzzle attempting to find the information they need, wading through multiple systems to find what they think is the single version of the truth. More often than not, they find they are missing pieces, pieces that may be crucial to growing the business rather than closing the business. across applications. Master data owners are defined to establish single sources of data (such as the CRM system owns client data). Other systems subscribe to the master data and changes are replicated to subscribers as they are made. This can be one way (no changes are allowed on the subscriber systems) or bi-directional. But at all times, the master data owner is current or up to date. And all data, whether internal or external, use the same processes and methods to move data from one place to another, leveraging the same validations, lookups and transformations enterprise wide, eliminating inconsistencies and siloed data. Once implemented, an enterprise integration solution improves performance and stability by reducing the number of moving parts and eliminating inconsistent data. Overall maintenance costs are mitigated by reducing touch points or the number of places that require modification when a business rule is changed or another data element is added. Most importantly, however, now decision makers can easily extract and piece together the information they need to grow their business, improve customer satisfaction and so on. So, in implementing an enterprise integration solution, companies can position themselves for the future, allowing for easy transition to data marts, data warehousing and, ultimately, business intelligence. Along this path, companies can achieve growth in size, intelligence and complexity. Truly, the question is not can companies afford to implement an enterprise integration solution, but can they afford not to.   Ralph Wheaton Microsoft Certified Technology Specialist Microsoft Certified Professional Developer Microsoft VTS-P BizTalk, .Net

• My Experience at Oracle !!! By Ayush Gupta

  - by Nadiya

  Normal 0 false false false EN-US X-NONE X-NONE Hi! My name is Ayush, a Gratuate from BITS Pilani and now working and living in Bangalore. I joined Oracle in August 2013 as a Senior Consultant (SC) and would like to share my experiences over the first couple of months with you.It has been a wonderful journey so far. The last two months have been very exciting for me. First of all I would like to mention that the training program at Oracle that we went through really prepared us well. It matured us and allowed us to go from developing small applications in college to big enterprise products. Two months of initial training has had a lasting impact for me. I am also really enjoying the knowledge I have gained so far and also learning new things in the form of product training. It's really fun to work here. We are treated like adults and we are responsible for our own workloads.With that I can't keep from mentioning the fun times we as a team have in the form of Young Leadership programme in Hotel Fortune Trinity which included Luxurious buffet lunch too. Wishing it could happen more frequently.  Oracle provides one of the best opportunities to learn various technologies across different platforms. What I like best about working at Oracle is the work life balance. With the option of flexible timings, one can easily enjoy planned evenings with friends or maybe working out at the fitness centre in your building. Be it the birthday celebrations at office or the day long team outing at a resort, It’s all together a different experience. Overall, you get to take full ownership of your project and they give you a free leash on how you design your enhancements/changes.As one of the largest international companies, Oracle is obviously an expert on exploring the potential and possibility of inexperienced new hires. We were taught how to make an outstanding team work in a group training session at the first few weeks. From this experience I realized that perfect cooperation is not about where you come from or what your study background is, everyone can find his or her own role to support the team. Even though I am not that skilled in technology, my background has significantly helped me in learning new technologies in Oracle.My idea and suggestion is: for new joiners, the will to learn is be more important than what you have learnt before. Colleagues here at Oracle are professionals in their field, always friendly and glad to help. So don’t worry, all you need to do is just be confident, and have a nice attitude, Oracle will let you fully display your talent. Come and join us, here you can always find a tailor made role for you! /* 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-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-family:"Calibri","sans-serif"; mso-ascii- mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi- mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

• Impressions of my ASUS eee slate EP121 - Dual core 4GB, 64GB SSD

  - by tonyrogerson

  This thing is lovely, very nice bluetooth keyboard that has nice feedback on the keypress, there is no mouse but you can use the stylus or get yourself a bluetooth mouse, me, I've opted for a Microsoft ARC mouse which is a delight to use, the USB doors are a pain to open for the first time if like me you don't have any finger nails. It came as a suprise that the slate shows four processors, Dual Core with multi-threading, I didn't really look at the processor I was more interested in the amount of memory and the SSD; you don't get the full 4GB even with the 64 bit version of Windows 7 installed (which I immediately upgraded to Ultimate through my MSDN subscription). The box is extremely responsive - extremely, it loads Winword in literally a second. I've got office 2010 and onenote 2010 on there now; one problem is that on applying all (43) windows updates since the upgrade the machine is still sat on step 3 of 3 on the start up configuring updates screen after about an hour, you can't turn this machine off without using a paper clip to reset it and as I have just found you need a paper clip :). Installing Windows 7 SP1 was effortless. One of the first things I did on it was to reduce the size of the font, by default its set at 125%, my eye sight is ok :) so I've set that back down. Amazon Kindle for the PC works really well, plenty of text on the screen when viewed portrait, the case it comes with also allows the slate to stand up in various positions - portrait, horizontal - seems stable enough. The wireless works well, seems to have a better signal than my other two laptop machines which is good news. The gadget passed the pose test at work :). I use offline files to keep a copy of all my work stuff locally, I'm not sure what it is, well, its probably my server but whenever I try and sync it runs for a couple of minutes then fails with network name no longer contactable, funnily enough its fine from my big laptop so I can only guess this may be a driver type issue on the EP121 itself - very odd and very annoying. I do a lot of presenting and need to plug into a VGA project because most sites that's all that is offered, the EP121 has a mini-hdmi output which is great except for this scenario, hdmi is digital, vga is analogue, you will struggle to find a cost effective solution, I found HDFury and also a device HP do, however, a better solution appears to be getting a USB graphics adapter for instance the one I've ordered is the ClimaxDigital USB 2.0 to DVI,VGA or HDMI Adaptor which gives everything I need - VGA and DVI output and great resolution as well - ok, so fingers crossed because I'm presenting next Wednesday in Edinburgh and not taking my 300kg lenovo w700 (I'm sure my back just sighed in relief) - it certainly works really well on my LED TV, the install was simple - it just works! One of the several reasons for buying this piece of kit was to use it on my LED TV to remote into my main machine to check stuff whilst sat in my living room, also to watch webcasts and lecture videos in comfort away from my office, because of the wireless speed and limitation I'm opting for a USB network adapter from Belkin - that will also allow me to take advantage of my home gigabit network, there are only 2 usb ports on the slate so I'm going to knock up a hub so connecting it in is straight forward and simple, I'm also going to purchase a second power supply so I don't have to faff about with that either.I now have the developer x64 edition of SQL Server 2008 R2, yes everything :) - about 16GB left to play with on the machine now but that will be fine, I'll put AdventureWorks on there so I can play and demo stuff which is all I'm after from this, my development machine is significantly more powerful and meets my storage needs too.Travel test this weekend and next week, I'm in Dundee for my final exam for the masters degree.

• Xsigo and Oracle's Storage

  - by Philippe Deverchère

  Xsigo, a virtual network infrastructure provider, has recently been acquired by Oracle. Following this acquisition, one might ask ourselves why it is important to Oracle and how Oracle's storage is going to benefit on the long term from this virtualized infrastructure layer. Well, the first thing to understand is that Virtual Networking addresses both network and storage connectivity. Oracle Virtual Networking, as the Xsigo technology is now called, connects any server to any network and storage, so this is not just about connecting servers to the Internet or Intranet. It is also for a large part connecting servers to NAS and SAN storage. Connecting servers to storage has become increasingly complex in the past few years because of the strong emergence of virtualization at the Operating System level. 50% of enterprise workloads are now virtualized, up from 18% in 2009, resulting in a strong consolidation of various applications in a high density server footprint. At the same time, server I/O capability increased 8x in the last 8 years. All this has pushed IT administrators to multiply the number of I/O connections in the back-end of their physical servers, resulting in a messy and very hard to manage networking infrastructure. Here is a typical view of a rack back-end when no virtual networking is used. We consider that today: - 75% of users have ten or more Ethernet ports per server - 85% of users have two or more SAN ports per server - 58% have had to add connectivity to a server specifically for VMs - 65% consider cable reduction a priority The average is 12 or more ports per server, resulting in an extremely complex infrastructure to manage. What Oracle wants to achieve with its Oracle Virtual Networking offering is pretty simple. The objective is to eliminate the complexity through a dramatic reduction of cabling between servers and storage/networks. It is also to provide a software based management system so that any server can be connected to any network or any storage, on demand, and without physical intervention on the infrastructure. At the end of the day, the picture on the left shows what one wants to get for the back-end of customer's racks: just a couple of connections on each physical server to provide a simple, agile and fast network infrastructure for both storage and networking access. This is exactly what the Oracle Virtual Networking solution does. It transforms a complex, error-prone, difficult to manage and expensive networking infrastructure into a simple, high performance and agile solution for the data center. Practically speaking, and for the sake of simplicity, imagine that each server just hosts a minimal number of physical InfiniBand HCAs (Host Channel Adapter) with two links (for redundancy) onto the Oracle Fabric Interconnect director. Using the Oracle Fabric Manager software, you'll then be able to create virtual NICs and HBAs (called vNIC and vHBA) that will be seen by the servers as standard NICs and HBAs and associate them to networks and storage systems which are physically connected to the back-end of the director through standard Fibre Channel and Ethernet GbE/10GbE ports. In addition to this incredibly simple "at-a-click" connectivity capability, the Oracle Virtual Networking solution offers powerful features such as network isolation, Quality of Service, advanced performance monitoring and non-disruptive reconfiguration, migration and scalability of networking infrastructure. So let's go back now to our initial question: why is Oracle Virtual Networking especially important to Oracle's storage solutions? After all, one could connect any storage in the back-end of the Oracle Fabric Interconnect directors, right? The answer is pretty simple: since Oracle owns both the virtualized networking infrastructure and the storage (ZFS-SA, Pillar Axiom and tape), it is possible to imagine several ways in the future to add value when it comes to connect storage to a virtualized storage network: enhanced storage capabilities, converged management between storage and network, improved diagnostic capabilities and optimized integration resulting in higher performance and unique features/functions. Of course, all this is not going to be done overnight, and future will tell us is which evolutions come first. But there is little doubt that the integration of Xsigo within Oracle is going to create opportunities for Oracle's storage!

• 13 Things From the Oracle Social Summit You Should Know

  - by Mike Stiles

  Oracle held its first annual Oracle Social Summit, “The School for the Socially Gifted,” this past week in Las Vegas.  If anyone came to the event uncertain as to why Oracle has such an interest in social, and what its plans for social are, they left with an entirely new vision of where social is headed, and why.For those unable to attend, I was able to keep my MacBook charged just long enough to capture some of the more pertinent takeaways.1. The social enterprise is inevitable.  Social technology is disrupting the hierarchies of big companies.  It’s a revolution in corporate structures, just as it has been in various governments.  It’s not crazy to ask yourself if your CEO is the next Mubarak.  (David Kilpatrick Author of “The Facebook Effect” and founder of the Techonomy Conference) 2. The social enterprise represents collaboration on steroids.  It’s tapping into the power of your people, as opposed to keeping them “in their place.”  3. 1 in every 7 humans on earth is an active Facebook user.  75% have posted a negative comment after a poor customer experience.  The average user will inform 53 people of a bad experience.4. Checking social media is the 2nd biggest use of phones now.  Reading posts from brands is 4th.5. 70% of marketers have little or no understanding of the social conversations happening around their brand.6. Advertising, when done well, is content we care about, preferably informed by those we trust.7. Acquiring low-quality fans through gimmicks, or focusing purely on fan acquisition is a mistake.  And relying purely on organic distribution is a mistake.  (John Yi, Head of Marketing Partnerships – Facebook)8. Using all this newfound data and insight serves to positively affect the customer experience.  It allows organizations to now leverage the investments they’ve made in social up to now.9. Social is not a marketing utopia where everything is free.  It’s pay to play.  The paid component is about driving attention.  10. We are only in the infancy of ad-targeting opportunities in social.  There’s an evolution underway from interest-based targeting to action-based targeting.11. There’s actually very little overlap of the people following you on different social platforms.  Don’t assume it’s the same audience on each.12. People who can create content and who also have an understanding of what drives that content are growing increasingly valuable.13. Oracle Social’s future is enterprise SRM, integrated across marketing, selling, service, HR and every other corner of the organization.And in case you thought those were the only gems to come out of the summit, you may want to keep an eye out for Tuesday’s Social Spotlight, ever so aptly titled “13 More Things from the Oracle Social Summit You Should Know.”

• First-Time GLSL Shadow Mapping Problems

  - by Locke

  I'm working on building out a 2.5D engine and having massive problems getting my shadows working. I'm at a point where I'm VERY close. So, let's see a picture to see what I have: As you can see above, the image has lighting -- but the shadow map is displaying incorrectly. The shadow map is shown in the bottom left hand side of the screen as a normal 2D texture, so we can see what it looks like at any given time. If you notice, it appears that the shadows are generating backwards in the wrong direction -- I think. But the problem is a little more deep -- I'm just plotting the shadow onto the screen, which I know is wrong -- I'm ignoring the actual test to see if we NEED to show a shadow. The incoming parameters all appear to be correct -- so there has to be something wrong with my shader code somewhere. Here's what my code looks like: VERTEX: uniform mat4 LightModelViewProjectionMatrix; varying vec3 Normal; // The eye-space normal of the current vertex. varying vec4 LightCoordinate; // The texture coordinate of the light of the current vertex. varying vec3 LightDirection; // The eye-space direction of the light. void main() { Normal = normalize(gl_NormalMatrix * gl_Normal); LightDirection = normalize(gl_NormalMatrix * gl_LightSource[0].position.xyz); LightCoordinate = LightModelViewProjectionMatrix * gl_Vertex; LightCoordinate.xy = ( LightCoordinate.xy * 0.5 ) + 0.5; gl_Position = ftransform(); gl_TexCoord[0] = gl_MultiTexCoord0; } FRAGMENT: uniform sampler2D DiffuseMap; uniform sampler2D ShadowMap; varying vec3 Normal; // The eye-space normal of the current vertex. varying vec4 LightCoordinate; // The texture coordinate of the light of the current vertex. varying vec3 LightDirection; // The eye-space direction of the light. void main() { vec4 Texel = texture2D(DiffuseMap, vec2(gl_TexCoord[0])); // Directional lighting //Build ambient lighting vec4 AmbientElement = gl_LightSource[0].ambient; //Build diffuse lighting float Lambert = max(dot(Normal, LightDirection), 0.0); //max(abs(dot(Normal, LightDirection)), 0.0); vec4 DiffuseElement = ( gl_LightSource[0].diffuse * Lambert ); vec4 LightingColor = ( DiffuseElement + AmbientElement ); LightingColor.r = min(LightingColor.r, 1.0); LightingColor.g = min(LightingColor.g, 1.0); LightingColor.b = min(LightingColor.b, 1.0); LightingColor.a = min(LightingColor.a, 1.0); LightingColor *= Texel; //Everything up to this point is PERFECT // Shadow mapping // ------------------------------ vec4 ShadowCoordinate = LightCoordinate / LightCoordinate.w; float DistanceFromLight = texture2D( ShadowMap, ShadowCoordinate.st ).z; float DepthBias = 0.001; float ShadowFactor = 1.0; if( LightCoordinate.w > 0.0 ) { ShadowFactor = DistanceFromLight < ( ShadowCoordinate.z + DepthBias ) ? 0.5 : 1.0; } LightingColor.rgb *= ShadowFactor; //gl_FragColor = LightingColor; //Yes, I know this is wrong, but the line above (gl_FragColor = LightingColor;) produces the wrong effect gl_FragColor = LightingColor * texture2D( ShadowMap, ShadowCoordinate.st ); } I wanted to make sure the coordinates were correct for the shadow map -- so that's why you see it applied to the image as it is below. But the depth for each point seems to be wrong -- the shadows SHOULD be opposite (look at how the image is -- the shaded areas from normal lighting are facing the opposite direction of the shadows). Maybe my matrices are bad or something going in? They're isolated and appear to be correct -- nothing else is going in unusual. When I view from the light's view and get the MVP matrices for it, they're correct. EDIT: Added an image so you can see what happens when I do the correct command at the end of the GLSL: That's the image when the last line is just glFragColor = LightingColor; Maybe someone has some idea of what I screwed up?

• Using the Script Component as a Conditional Split

  This is a quick walk through on how you can use the Script Component to perform Conditional Split like behaviour, splitting your data across multiple outputs. We will use C# code to decide what does flows to which output, rather than the expression syntax of the Conditional Split transformation. Start by setting up the source. For my example the source is a list of SQL objects from sys.objects, just a quick way to get some data: SELECT type, name FROM sys.objects type name S syssoftobjrefs F FK_Message_Page U Conference IT queue_messages_23007163 Shown above is a small sample of the data you could expect to see. Once you have setup your source, add the Script Component, selecting Transformation when prompted for the type, and connect it up to the source. Now open the component, but don’t dive into the script just yet. First we need to select some columns. Select the Input Columns page and then select the columns we want to uses as part of our filter logic. You don’t need to choose columns that you may want later, this is just the columns used in the script itself. Next we need to add our outputs. Select the Inputs and Outputs page.You get one by default, but we need to add some more, it wouldn’t be much of a split otherwise. For this example we’ll add just one more. Click the Add Output button, and you’ll see a new output is added. Now we need to set some properties, so make sure our new Output 1 is selected. In the properties grid change the SynchronousInputID property to be our input Input 0, and  change the ExclusionGroup property to 1. Now select Ouput 0 and change the ExclusionGroup property to 2. This value itself isn’t important, provided each output has a different value other than zero. By setting this property on both outputs it allows us to split the data down one or the other, making each exclusive. If we left it to 0, that output would get all the rows. It can be a useful feature allowing you to copy selected rows to one output whilst retraining the full set of data in the other. Now we can go back to the Script page and start writing some code. For the example we will do a very simple test, if the value of the type column is U, for user table, then it goes down the first output, otherwise it ends up in the other. This mimics the exclusive behaviour of the conditional split transformation. public override void Input0_ProcessInputRow(Input0Buffer Row) { // Filter all user tables to the first output, // the remaining objects down the other if (Row.type.Trim() == "U") { Row.DirectRowToOutput0(); } else { Row.DirectRowToOutput1(); } } The code itself is very simple, a basic if clause that determines which of the DirectRowToOutput methods we call, there is one for each output. Of course you could write a lot more code to implement some very complex logic, but the final direction is still just a method call. If we now close the script component, we can hook up the outputs and test the package. Your numbers will vary depending on the sample database but as you can see we have clearly split out input data into two outputs. As a final tip, when adding the outputs I would normally rename them, changing the Name in the Properties grid. This means the generated methods follow the pattern as do the path label shown on the design surface, making everything that much easier to recognise.

• Converting openGl code to DirectX

  - by Fredrik Boston Westman

  First of all, this is kind of a follow up question on @byte56 excellent anwser on this question concerning picking algorithms. I'm trying to convert one of his code examples to directX 11 however I have run in to some problems ( I can pick but the picking is way off), and I wanted to make sure I had done it rigth before moving on and checking the rest of my code. I am not that familiar with openGl but I can imagine openGl has diffrent coordinations systems, and functions that alters how you must implement to code abit. This is his code example: public Ray GetPickRay() { int mouseX = Mouse.getX(); int mouseY = WORLD.Byte56Game.getHeight() - Mouse.getY(); float windowWidth = WORLD.Byte56Game.getWidth(); float windowHeight = WORLD.Byte56Game.getHeight(); //get the mouse position in screenSpace coords double screenSpaceX = ((float) mouseX / (windowWidth / 2) - 1.0f) * aspectRatio; double screenSpaceY = (1.0f - (float) mouseY / (windowHeight / 2)); double viewRatio = Math.tan(((float) Math.PI / (180.f/ViewAngle) / 2.00f))* zoomFactor; screenSpaceX = screenSpaceX * viewRatio; screenSpaceY = screenSpaceY * viewRatio; //Find the far and near camera spaces Vector4f cameraSpaceNear = new Vector4f((float) (screenSpaceX * NearPlane), (float) (screenSpaceY * NearPlane), (float) (-NearPlane), 1); Vector4f cameraSpaceFar = new Vector4f((float) (screenSpaceX * FarPlane), (float) (screenSpaceY * FarPlane), (float) (-FarPlane), 1); //Unproject the 2D window into 3D to see where in 3D we're actually clicking Matrix4f tmpView = Matrix4f(view); Matrix4f invView = (Matrix4f) tmpView.invert(); Vector4f worldSpaceNear = new Vector4f(); Matrix4f.transform(invView, cameraSpaceNear, worldSpaceNear); Vector4f worldSpaceFar = new Vector4f(); Matrix4f.transform(invView, cameraSpaceFar, worldSpaceFar); //calculate the ray position and direction Vector3f rayPosition = new Vector3f(worldSpaceNear.x, worldSpaceNear.y, worldSpaceNear.z); Vector3f rayDirection = new Vector3f(worldSpaceFar.x - worldSpaceNear.x, worldSpaceFar.y - worldSpaceNear.y, worldSpaceFar.z - worldSpaceNear.z); rayDirection.normalise(); return new Ray(rayPosition, rayDirection); } All rigths reserved to him of course This is my DirectX 11 code : void GraphicEngine::pickRayVector(float mouseX, float mouseY,XMVECTOR& pickRayInWorldSpacePos, XMVECTOR& pickRayInWorldSpaceDir) { float PRVecX, PRVecY; float nearPlane = 0.1f; float farPlane = 200.0f; floar viewAngle = 0.4 * 3.14; PRVecX = ((( 2.0f * mouseX) / ClientWidth ) - 1 ) * tan((viewAngle)/2); PRVecY = (1-(( 2.0f * mouseY) / ClientHeight)) * tan((viewAngle)/2); XMVECTOR cameraSpaceNear = XMVectorSet(PRVecX * nearPlane,PRVecY * nearPlane, -nearPlane, 1.0f); XMVECTOR cameraSpaceFar = XMVectorSet(PRVecX * farPlane,PRVecY * farPlane, -farPlane, 1.0f); // Transform 3D Ray from View space to 3D ray in World space XMMATRIX invMat; XMVECTOR matInvDeter; invMat = XMMatrixInverse(&matInvDeter, cam->getCameraView()); //Inverse of View Space matrix is World space matrix XMVECTOR worldSpaceNear = XMVector3TransformCoord(cameraSpaceNear, invMat); XMVECTOR worldSpaceFar = XMVector3TransformCoord(cameraSpaceFar, invMat); pickRayInWorldSpacePos = worldSpaceNear; pickRayInWorldSpaceDir = worldSpaceFar-worldSpaceNear; pickRayInWorldSpaceDir = XMVector3Normalize(pickRayInWorldSpaceDir); } A couple of notes: The mouse coordinates are already converted so that the top left corner of the client window would be (0,0) and the bottom rigth (800,600) ( or whatever resolution you would have) I hadn't used any far or near plane before, so i just made some arbitrary number up for them. To my understanding it shouldnt matter as long as the object you are trying to pick is in between the range of thoese numbers The viewAngle is the same angle that I used when setting the camera view with XMMatrixPerspectiveFovLH , I just hadn't made it a member variable of my Camera class yet. I removed the variable aspectRation and zoomFactor because I assumed that they where related to some specific function of his game. Now I'm not sure, but I think the problems lies either withing the mouse to viewspace conversion, maby that we use diffrent coordinations systems. Either that or how i transform the matrixes in the the end, because i know order is important when it comes to matrixes. Any help is appriciated! Thanks in advance. Edit: One more note, my code is in c++

• Generate a merge statement from table structure

  - by Nigel Rivett

  This code generates a merge statement joining on he natural key and checking all other columns to see if they have changed. The full version deals with type 2 processing and an audit trail but this version is useful. Just the insert or update part is handy too. Change the table at the top (spt_values in master in the version) and the join columns for the merge in @nk. The output generated is at the top and the code to run to generate it below. Output merge spt_values a using spt_values b on a.name = b.name and a.number = b.number and a.type = b.type when matched and (1=0 or (a.low b.low) or (a.low is null and b.low is not null) or (a.low is not null and b.low is null) or (a.high b.high) or (a.high is null and b.high is not null) or (a.high is not null and b.high is null) or (a.status b.status) or (a.status is null and b.status is not null) or (a.status is not null and b.status is null) ) then update set low = b.low , high = b.high , status = b.status when not matched by target then insert ( name , number , type , low , high , status ) values ( b.name , b.number , b.type , b.low , b.high , b.status ); Generator set nocount on declare @t varchar(128) = 'spt_values' declare @i int = 0 -- this is the natural key on the table used for the merge statement join declare @nk table (ColName varchar(128)) insert @nk select 'Number' insert @nk select 'Name' insert @nk select 'Type' declare @cols table (seq int, nkseq int, type int, colname varchar(128)) ;with cte as ( select ordinal_position, type = case when columnproperty(object_id(@t), COLUMN_NAME,'IsIdentity') = 1 then 3 when nk.ColName is not null then 1 else 0 end, COLUMN_NAME from information_schema.columns c left join @nk nk on c.column_name = nk.ColName where table_name = @t ) insert @cols (seq, nkseq, type, colname) select ordinal_position, row_number() over (partition by type order by ordinal_position) , type, COLUMN_NAME from cte declare @result table (i int, j int, k int, data varchar(500)) select @i = @i + 1 insert @result (i, data) select @i, 'merge ' + @t + ' a' select @i = @i + 1 insert @result (i, data) select @i, ' using cte b' select @i = @i + 1 insert @result (i, j, data) select @i, nkseq, ' ' + case when nkseq = 1 then 'on' else 'and' end + ' a.' + ColName + ' = b.' + ColName from @cols where type = 1 select @i = @i + 1 insert @result (i, data) select @i, ' when matched and (1=0' select @i = @i + 1 insert @result (i, j, k, data) select @i, seq, 1, ' or (a.' + ColName + ' b.' + ColName + ')' + ' or (a.' + ColName + ' is null and b.' + ColName + ' is not null)' + ' or (a.' + ColName + ' is not null and b.' + ColName + ' is null)' from @cols where type 1 select @i = @i + 1 insert @result (i, data) select @i, ' )' select @i = @i + 1 insert @result (i, data) select @i, ' then update set' select @i = @i + 1 insert @result (i, j, data) select @i, nkseq, ' ' + case when nkseq = 1 then ' ' else ', ' end + colname + ' = b.' + colname from @cols where type = 0 select @i = @i + 1 insert @result (i, data) select @i, ' when not matched by target then insert' select @i = @i + 1 insert @result (i, data) select @i, ' (' select @i = @i + 1 insert @result (i, j, data) select @i, seq, ' ' + case when seq = 1 then ' ' else ', ' end + colname from @cols where type 3 select @i = @i + 1 insert @result (i, data) select @i, ' )' select @i = @i + 1 insert @result (i, data) select @i, ' values' select @i = @i + 1 insert @result (i, data) select @i, ' (' select @i = @i + 1 insert @result (i, j, data) select @i, seq, ' ' + case when seq = 1 then ' ' else ', ' end + 'b.' + colname from @cols where type 3 select @i = @i + 1 insert @result (i, data) select @i, ' );' select data from @result order by i,j,k,data

• problem with frustum AABB culling in DirectX

  - by Matthew Poole

  Hi, I am currently working on a project with a few friends, and I am trying to get frustum culling working. Every single tutorial or article I go to shows that my math is correct and that this should be working. I thought maybe posting here, somebody would catch something I could not. Thank you. Here are the important code snippets /create the projection matrix void CD3DCamera::SetLens(float fov, float aspect, float nearZ, float farZ) { D3DXMatrixPerspectiveFovLH(&projMat, D3DXToRadian(fov), aspect, nearZ, farZ); } //build the view matrix after changes have been made to camera void CD3DCamera::BuildView() { //keep axes orthoganal D3DXVec3Normalize(&look, &look); //up D3DXVec3Cross(&up, &look, &right); D3DXVec3Normalize(&up, &up); //right D3DXVec3Cross(&right, &up, &look); D3DXVec3Normalize(&right, &right); //fill view matrix float x = -D3DXVec3Dot(&position, &right); float y = -D3DXVec3Dot(&position, &up); float z = -D3DXVec3Dot(&position, &look); viewMat(0,0) = right.x; viewMat(1,0) = right.y; viewMat(2,0) = right.z; viewMat(3,0) = x; viewMat(0,1) = up.x; viewMat(1,1) = up.y; viewMat(2,1) = up.z; viewMat(3,1) = y; viewMat(0,2) = look.x; viewMat(1,2) = look.y; viewMat(2,2) = look.z; viewMat(3,2) = z; viewMat(0,3) = 0.0f; viewMat(1,3) = 0.0f; viewMat(2,3) = 0.0f; viewMat(3,3) = 1.0f; } void CD3DCamera::BuildFrustum() { D3DXMATRIX VP; D3DXMatrixMultiply(&VP, &viewMat, &projMat); D3DXVECTOR4 col0(VP(0,0), VP(1,0), VP(2,0), VP(3,0)); D3DXVECTOR4 col1(VP(0,1), VP(1,1), VP(2,1), VP(3,1)); D3DXVECTOR4 col2(VP(0,2), VP(1,2), VP(2,2), VP(3,2)); D3DXVECTOR4 col3(VP(0,3), VP(1,3), VP(2,3), VP(3,3)); // Planes face inward frustum[0] = (D3DXPLANE)(col2); // near frustum[1] = (D3DXPLANE)(col3 - col2); // far frustum[2] = (D3DXPLANE)(col3 + col0); // left frustum[3] = (D3DXPLANE)(col3 - col0); // right frustum[4] = (D3DXPLANE)(col3 - col1); // top frustum[5] = (D3DXPLANE)(col3 + col1); // bottom // Normalize the frustum for( int i = 0; i < 6; ++i ) D3DXPlaneNormalize( &frustum[i], &frustum[i] ); } bool FrustumCheck(D3DXVECTOR3 max, D3DXVECTOR3 min, const D3DXPLANE* frustum) { // Test assumes frustum planes face inward.

• Lessons Building KeyRef (a .NET developer learning Rails)

  - by Liam McLennan

  Just because I like to build things, and I like to learn, I have been working on a keyboard shortcut reference site. I am using this as an opportunity to improve my ruby and rails skills. The first few days were frustrating. Perhaps the learning curve of all the fun new toys was a bit excessive. Finally tonight things have really started to come together. I still don’t understand the rails built-in testing support but I will get there. Interesting Things I Learned Tonight RubyMine IDE Tonight I switched to RubyMine instead of my usual Notepad++. I suspect RubyMine is a powerful tool if you know how to use it – but I don’t. At the moment it gives me errors about some gems not being activated. This is another one of those things that I will get to. I have also noticed that the editor functions significantly differently to the editors I am used to. For example, in visual studio and notepad++ if you place the cursor at the start of a line and press left arrow the cursor is sent to the end of the previous line. In RubyMine nothing happens. Haml Haml is my favourite view engine. For my .NET work I have been using its non-union Mexican CLR equivalent – nHaml. Multiple CSS Classes To define a div with more than one css class haml lets you chain them together with a ‘.’, such as: .span-6.search_result contents of the div go here Indent Consistency I also learnt tonight that both haml and nhaml complain if you are not consistent about indenting. As a consequence of the move from notepad++ to RubyMine my haml views ended up with some tab indenting and some space indenting. For the view to render all of the indents within a view must be consistent. Sorting Arrays I guessed that ruby would be able to sort an array alphabetically by a property of the elements so my first attempt was: Application.all.sort {|app| app.name} which does not work. You have to supply a comparer (much like .NET). The correct sort is: Application.all.sort {|a,b| a.name.downcase <=> b.name.downcase} MongoMapper Find by Id Since document databases are just fancy key-value stores it is essential to be able to easily search for a document by its id. This functionality is so intrinsic that it seems that the MongoMapper author did not bother to document it. To search by id simply pass the id to the find method: Application.find(‘4c19e8facfbfb01794000002’) Rails And CoffeeScript I am a big fan of CoffeeScript so integrating it into this application is high on my priorities. My first thought was to copy Dr Nic’s strategy. Unfortunately, I did not get past step 1. Install Node.js. I am doing my development on Windows and node is unix only. I looked around for a solution but eventually had to concede defeat… for now. Quicksearch The front page of the application I am building displays a list of applications. When the user types in the search box I want to reduce the list of applications to match their search. A quick googlebing turned up quicksearch, a jquery plugin. You simply tell quicksearch where to get its input (the search textbox) and the list of items to filter (the divs containing the names of applications) and it just works. Here is the code: $('#app_search').quicksearch('.search_result'); Summary I have had a productive evening. The app now displays a list of applications, allows them to be sorted and links through to an application page when an application is selected. Next on the list is to display the set of keyboard shortcuts for an application.
