ADF version of "Modern" dialog windows

- by Martin Deh

It is no surprise with the popularity of the i-devices (iphone, ipad), that many of the iOS UI based LnF (look and feel) would start to inspire web designers to incorporate the same LnF into their web sites. Take for example, a normal dialog popup. In the iOS world, the LnF becomes a bit more elegant by add just a simple element as a "floating" close button: In this blog post, I will describe how this can be accomplished using OOTB ADF components and CSS3 style elements. There are two ways that this can be achieved. The easiest way is to simply replace the default image, which looks like this, and adjust the af|panelWindow:close-icon-style skin selector. Using this simple technique, you can come up with this: The CSS code to produce this effect is pretty straight forward: af|panelWindow.test::close-icon-style{ background-image: url("../popClose.gif"); line-height: 10px; position: absolute; right: -10px; top: -10px; height:38px; width:38px; outline:none; } You can see from the CSS, the position of the region, which holds the image, is relocated based on the position based attributes. Also, the addition of the "outline" attribute removes the border that is visible in Chrome and IE. The second example, is based on not having an image to produce the close button. Like the previous sample, I will use the OOTB panelWindow. However, this time I will use a OOTB commandButton to replace the image. The construct of the components looks like this: The commandButton is positioned first in the hierarchy making the re-positioning easier. The commandButton will also need a style class assigned to it (i.e. closeButton), which will allow for the positioning and the over-riding of the default skin attributes of a default button. In addition, the closeIconVisible property is set to false, since the default icon is no longer needed. Once this is done, the rest is in the CSS. Here is the sample that I created that was used for an actual customer POC: The CSS code for the button: af|commandButton.closeButton, af|commandButton.closeButton af|commandButton:text-only{ line-height: 10px; position: absolute; right: -10px; top: -10px; -webkit-border-radius: 70px; -moz-border-radius: 70px; -ms-border-radius: 70px; border-radius: 70px; background-image:none; border:#828c95 1px solid; background-color:black; font-weight: bold; text-align: center; text-decoration: none; color:white; height:30px; width:30px; outline:none; } The CSS uses the border radius to create the round effect on the button (in IE 8, since border-radius is not supported, this will only work with some added code). Also, I add the box-shadow attribute to the panelWindow style class to give it a nice shadowing effect.

OpenGL 3 and the Radeon HD 4850x2

- by rotard

A while ago, I picked up a copy of the OpenGL SuperBible fifth edition and slowly and painfully started teaching myself OpenGL the 3.3 way, after having been used to the 1.0 way from school way back when. Making things more challenging, I am primarily a .NET developer, so I was working in Mono with the OpenTK OpenGL wrapper. On my laptop, I put together a program that let the user walk around a simple landscape using a couple shaders that implemented per-vertex coloring and lighting and texture mapping. Everything was working brilliantly until I ran the same program on my desktop. Disaster! Nothing would render! I have chopped my program down to the point where the camera sits near the origin, pointing at the origin, and renders a square (technically, a triangle fan). The quad renders perfectly on my laptop, coloring, lighting, texturing and all, but the desktop renders a small distorted non-square quadrilateral that is colored incorrectly, not affected by the lights, and not textured. I suspect the graphics card is at fault, because I get the same result whether I am booted into Ubuntu 10.10 or Win XP. I did find that if I pare the vertex shader down to ONLY outputting the positional data and the fragment shader to ONLY outputting a solid color (white) the quad renders correctly. But as SOON as I start passing in color data (whether or not I use it in the fragment shader) the output from the vertex shader is distorted again. The shaders follow. I left the pre-existing code in, but commented out so you can get an idea what I was trying to do. I'm a noob at glsl so the code could probably be a lot better. My laptop is an old lenovo T61p with a Centrino (Core 2) Duo and an nVidia Quadro graphics card running Ubuntu 10.10 My desktop has an i7 with a Radeon HD 4850 x2 (single card, dual GPU) from Saphire dual booting into Ubuntu 10.10 and Windows XP. The problem occurs in both XP and Ubuntu. Can anyone see something wrong that I am missing? What is "special" about my HD 4850x2? string vertexShaderSource = @" #version 330 precision highp float; uniform mat4 projection_matrix; uniform mat4 modelview_matrix; //uniform mat4 normal_matrix; //uniform mat4 cmv_matrix; //Camera modelview. Light sources are transformed by this matrix. //uniform vec3 ambient_color; //uniform vec3 diffuse_color; //uniform vec3 diffuse_direction; in vec4 in_position; in vec4 in_color; //in vec3 in_normal; //in vec3 in_tex_coords; out vec4 varyingColor; //out vec3 varyingTexCoords; void main(void) { //Get surface normal in eye coordinates //vec4 vEyeNormal = normal_matrix * vec4(in_normal, 0); //Get vertex position in eye coordinates //vec4 vPosition4 = modelview_matrix * vec4(in_position, 0); //vec3 vPosition3 = vPosition4.xyz / vPosition4.w; //Get vector to light source in eye coordinates //vec3 lightVecNormalized = normalize(diffuse_direction); //vec3 vLightDir = normalize((cmv_matrix * vec4(lightVecNormalized, 0)).xyz); //Dot product gives us diffuse intensity //float diff = max(0.0, dot(vEyeNormal.xyz, vLightDir.xyz)); //Multiply intensity by diffuse color, force alpha to 1.0 //varyingColor.xyz = in_color * diff * diffuse_color.xyz; varyingColor = in_color; //varyingTexCoords = in_tex_coords; gl_Position = projection_matrix * modelview_matrix * in_position; }"; string fragmentShaderSource = @" #version 330 //#extension GL_EXT_gpu_shader4 : enable precision highp float; //uniform sampler2DArray colorMap; //in vec4 varyingColor; //in vec3 varyingTexCoords; out vec4 out_frag_color; void main(void) { out_frag_color = vec4(1,1,1,1); //out_frag_color = varyingColor; //out_frag_color = vec4(varyingColor, 1) * texture(colorMap, varyingTexCoords.st); //out_frag_color = vec4(varyingColor, 1) * texture(colorMap, vec3(varyingTexCoords.st, 0)); //out_frag_color = vec4(varyingColor, 1) * texture2DArray(colorMap, varyingTexCoords); }"; Note that in this code the color data is accepted but not actually used. The geometry is outputted the same (wrong) whether the fragment shader uses varyingColor or not. Only if I comment out the line varyingColor = in_color; does the geometry output correctly. Originally the shaders took in vec3 inputs, I only modified them to take vec4s while troubleshooting.

Using Definition of Done to Drive Agile Maturity

- by Dylan Smith

I’ve been an Agile Coach at a lot of different clients over the years, and I want to share an approach I use to help them adopt and mature over time. It’s important to realize that “Agile” is not a black/white yes/no thing. Teams can be varying degrees of agile. I think of this as their agile maturity level. When I coach teams I want them to start out being a little agile, and get more agile as they mature. The approach I teach them is to use the definition of done as a technique to continuously improve their agile maturity over time. We’re probably all familiar with the concept of “Done Done” that represents what *actually* being done a feature means. Not just when a developer says he’s done right after he writes that last line of code that makes the feature kind-of work. Done Done means the coding is done, it’s been tested, installers and deployment packages have been created, user manuals have been updated, architecture docs have been updated, etc. To enable teams to internalize the concept of “Done Done”, they usually get together and come up with their Definition of Done (DoD) that defines all the activities that need to be completed before a feature is considered Done Done. The Done Done technique typically is applied only to features (aka User Stories). What I do is extend this to apply to several concepts such as User Stories, Sprints, Releases (and sometimes Check-Ins). During project kick-off I’ll usually sit down with the team and go through an exercise of creating DoD’s for each of these concepts (Stories/Sprints/Releases). We’ll usually start by just brainstorming a bunch of activities that could end up in these various DoD’s. Here’s some examples: Code Reviews StyleCop FxCop User Manuals Updated Architecture Docs Updated Tested by QA Tested by UAT Installers Created Support Knowledge Base Updated Deployment Instructions (for Ops) written Automated Unit Tests Run Automated Integration Tests Run Then we start by arranging these activities into the place they occur today (e.g. Do you do UAT testing only once per release? every sprint? every feature?). If the team was previously Waterfall most of these activities probably end up in the Release DoD. An extremely mature agile team would probably have most of these activities in the DoD for the User Stories (because an extremely mature agile team will probably do continuous deployment and release every story). So what we need to do as a team, is work to move these activities from their current home (Release DoD) down into the Sprint DoD and eventually into the User Story DoD (and maybe into the lower-level Check-In DoD if we decide to use that). We don’t have to move them all down to User Story immediately, but as a team we figure out what we think we’re capable of moving down to the Sprint cycle, and Story cycle immediately, and that becomes our starting DoD’s. Over time the team makes an effort to continue moving activities down from Release->Sprint->Story as they become more agile and more mature. I try to encourage them to envision a world in which they deploy to production as each User Story is completed. They would need to be updating User Manuals, creating installers, doing UAT testing (typical Release cycle activities) on every single User Story. They may never actually reach that point, but they should envision that, and strive to keep driving the activities down closer to the User Story cycle s they mature. This is a great technique to give a team an easy-to-follow roadmap to mature their agile practices over time. Sure there’s other aspects to maturity outside of this, but it’s a great technique, that’s easy to visualize, to drive agility into the team. Just keep moving those activities (aka “gates”) down the board from Release->Sprint->Story. I’ll try to give an example of what a recent client of mine had for their DoD’s (this is from memory, so probably not 100% accurate): Release Create/Update deployment Instructions For Ops Instructional Videos Updated Run manual regression test suite UAT Testing In this case that meant deploying to an environment shared across the enterprise that mirrored production and asking other business groups to test their own apps to ensure we didn’t break anything outside our system Sprint Deploy to UAT Environment But not necessarily actually request UAT testing occur User Guides updated Sprint Features Video Created In this case we decided to create a video each sprint showing off the progress (video version of Sprint Demo) User Story Manual Test scripts developed and run Tested by BA Deployed in shared QA environment Using automated deployment process Peer Code Review Code Check-In Compiled (warning-free) Passes StyleCop Passes FxCop Create installer packages Run Automated Tests Run Automated Integration Tests PS – One of my clients had a great question when we went through this activity. They said that if a Sprint is by definition done when the end-date rolls around (time-boxed), isn’t a DoD on a sprint meaningless – it’s done on the end-date regardless of whether those other activities are complete or not? My answer is that while that statement is true – the sprint is done regardless when the end date rolls around – if the DoD activities haven’t been completed I would consider the Sprint a failure (similar to not completing what was committed/planned – failure may be too strong a word but you get the idea). In the Retrospective that will become an agenda item to discuss and understand why we weren’t able to complete the activities we agreed would need to be completed each Sprint.

Cocos2d: Moving background on update: offsett issue

- by mm24

working with Objective C, iOS and Cocos2d I am developing a vertical scrolling shooter game for iPhone (retina display models with 640 width x 960 height pixel resolution). My basic algorithm works as following: I create two instances of an image that has exactly 640 width x 960 height pixel of resolution, which we will call imageA and imageB I then set the two imags with exactly 480.0f of offset from each other, as the screenSize of a CCScene is set by default to 480.0f. At each update method call I move the two images by the same value. I make sure that their offsett stays to 480.0f However when running the game I see a 1 pixel height line between the two images. This literally bugs me and would like to adjust this. What am I doing wrong? This is a zoom in on the background when the "offsett line" is visible. The white line you can see divides the two background images and is not meant to exist as both images are completely black :): If I change the yPositionOfSecondElement value to 479.0f until the first loop the two images overlap correctly, but as soon as the loop starts the two images starts having an offsett of -1.0f. Here is the initialization code: -(void) init { //... screenHeight = 480.0f; yPositionOfSecondElement= screenHeight;//I tried subtracting an offsett of -1 but eventually the image would go wrong again yPositionOfFirstElement = 0.0f; loopedBackgroundImageInstanceA = [BackgroundLoopedImage loopImageForLevel:levelName]; loopedBackgroundImageInstanceA.anchorPoint = CGPointMake(0.5f, 0.0f); loopedBackgroundImageInstanceA.position = CGPointMake(160.0f, yPositionOfFirstElement); [node addChild:loopedBackgroundImageInstanceA z:zLevelBackground]; //loopedBackgroundImageInstanceA.color= ccRED; loopedBackgroundImageInstanceB = [BackgroundLoopedImage loopImageForLevel:levelName]; loopedBackgroundImageInstanceB.anchorPoint = CGPointMake(0.5f, 0.0f); loopedBackgroundImageInstanceB.position = CGPointMake(160.0f, yPositionOfSecondElement); [node addChild:loopedBackgroundImageInstanceB z:zLevelBackground]; //.... } And here is the move code called at each update: -(void) moveBackgroundSprites:(BackgroundLoopedImage*)imageA :(BackgroundLoopedImage*)imageB :(ccTime)delta { isEligibleToMove=false; //This is done to avoid rounding errors float yStep = delta * [GameController sharedGameController].currentBackgroundSpeed; NSString* formattedNumber = [NSString stringWithFormat:@"%.02f", yStep]; yStep = atof([formattedNumber UTF8String]); //First should adjust position of images [self adjustPosition:imageA :imageB]; //The can get the actual image position CGPoint posA = imageA.position; CGPoint posB = imageB.position; //Here could verify if the checksum is equal to the required difference (should be 479.0f) if (![self verifyCheckSum:posA :posB]) { CCLOG(@"does not comply A"); } //At this stage can compute the hypotetical new position CGPoint newPosA = CGPointMake(posA.x, posA.y - yStep); CGPoint newPosB = CGPointMake(posB.x, posB.y - yStep); // Reposition stripes when they're out of bounds if (newPosA.y <= -yPositionOfSecondElement) { newPosA.y = yPositionOfSecondElement; [imageA shuffle]; if (timeElapsed>=endTime && hasReachedEndLevel==FALSE) { hasReachedEndLevel=TRUE; shouldMoveImageEnd=TRUE; } } else if (newPosB.y <= -yPositionOfSecondElement) { newPosB.y = yPositionOfSecondElement; [imageB shuffle]; if (timeElapsed>=endTime && hasReachedEndLevel==FALSE) { hasReachedEndLevel=TRUE; shouldMoveImageEnd=TRUE; } } //Here should verify that the check sum is equal to 479.0f if (![self verifyCheckSum:posA :posB]) { CCLOG(@"does not comply B"); } imageA.position = newPosA; imageB.position = newPosB; //Here could verify that the check sum is equal to 479.0f if (![self verifyCheckSum:posA :posB]) { CCLOG(@"does not comply C"); } isEligibleToMove=true; } -(BOOL) verifyCheckSum:(CGPoint)posA :(CGPoint)posB { BOOL comply = false; float sum = 0.0f; if (posA.y > posB.y) { sum = posA.y - posB.y; } else if (posB.y > posA.y){ sum = posB.y - posA.y; } else{ return false; } if (sum!=yPositionOfSecondElement) { comply= false; } else{ comply=true; } return comply; } And here is what happens on the update: if(shouldMoveImageA && shouldMoveImageB) { if (isEligibleToMove) { [self moveBackgroundSprites:loopedBackgroundImageInstanceA :loopedBackgroundImageInstanceB :delta]; } Forget about shouldMoveImageA and shouldMoveImageB, this is just for when the background reaches the end of level, this works.

Cloud to On-Premise Connectivity Patterns

- by Rajesh Raheja

Do you have a requirement to convert an Opportunity in Salesforce.com to an Order/Quote in Oracle E-Business Suite? Or maybe you want the creation of an Oracle RightNow Incident to trigger an on-premise Oracle E-Business Suite Service Request creation for RMA and Field Scheduling? If so, read on. In a previous blog post, I discussed integrating TO cloud applications, however the use cases above are the reverse i.e. receiving data FROM cloud applications (SaaS) TO on-premise applications/databases that sit behind a firewall. Oracle SOA Suite is assumed to be on-premise with with Oracle Service Bus as the mediation and virtualization layer. The main considerations for the patterns are are security i.e. shielding enterprise resources; and scalability i.e. minimizing firewall latency. Let me use an analogy to help visualize the patterns: the on-premise system is your home - with your most valuable possessions - and the SaaS app is your favorite on-line store which regularly ships (inbound calls) various types of parcels/items (message types/service operations). You need the items at home (on-premise) but want to safe guard against misguided elements of society (internet threats) who may masquerade as postal workers and vandalize property (denial of service?). Let's look at the patterns. Pattern: Pull from Cloud The on-premise system polls from the SaaS apps and picks up the message instead of having it delivered. This may be done using Oracle RightNow Object Query Language or SOAP APIs. This is particularly suited for certain integration approaches wherein messages are trickling in, can be centralized and batched e.g. retrieving event notifications on an hourly schedule from the Oracle Messaging Service. To compare this pattern with the home analogy, you are avoiding any deliveries to your home and instead go to the post office/UPS/Fedex store to pick up your parcel. Every time. Pros: On-premise assets not exposed to the Internet, firewall issues avoided by only initiating outbound connections Cons: Polling mechanisms may affect performance, may not satisfy near real-time requirements Pattern: Open Firewall Ports The on-premise system exposes the web services that needs to be invoked by the cloud application. This requires opening up firewall ports, routing calls to the appropriate internal services behind the firewall. Fusion Applications uses this pattern, and auto-provisions the services on the various virtual hosts to secure the topology. This works well for service integration, but may not suffice for large volume data integration. Using the home analogy, you have now decided to receive parcels instead of going to the post office every time. A door mail slot cut out allows the postman can drop small parcels, but there is still concern about cutting new holes for larger packages. Pros: optimal pattern for near real-time needs, simpler administration once the service is provisioned Cons: Needs firewall ports to be opened up for new services, may not suffice for batch integration requiring direct database access Pattern: Virtual Private Networking The on-premise network is "extended" to the cloud (or an intermediary on-demand / managed service offering) using Virtual Private Networking (VPN) so that messages are delivered to the on-premise system in a trusted channel. Using the home analogy, you entrust a set of keys with a neighbor or property manager who receives the packages, and then drops it inside your home. Pros: Individual firewall ports don't need to be opened, more suited for high scalability needs, can support large volume data integration, easier management of one connection vs a multitude of open ports Cons: VPN setup, specific hardware support, requires cloud provider to support virtual private computing Pattern: Reverse Proxy / API Gateway The on-premise system uses a reverse proxy "API gateway" software on the DMZ to receive messages. The reverse proxy can be implemented using various mechanisms e.g. Oracle API Gateway provides firewall and proxy services along with comprehensive security, auditing, throttling benefits. If a firewall already exists, then Oracle Service Bus or Oracle HTTP Server virtual hosts can provide reverse proxy implementations on the DMZ. Custom built implementations are also possible if specific functionality (such as message store-n-forward) is needed. In the home analogy, this pattern sits in between cutting mail slots and handing over keys. Instead, you install (and maintain) a mailbox in your home premises outside your door. The post office delivers the parcels in your mailbox, from where you can securely retrieve it. Pros: Very secure, very flexible Cons: Introduces a new software component, needs DMZ deployment and management Pattern: On-Premise Agent (Tunneling) A light weight "agent" software sits behind the firewall and initiates the communication with the cloud, thereby avoiding firewall issues. It then maintains a bi-directional connection either with pull or push based approaches using (or abusing, depending on your viewpoint) the HTTP protocol. Programming protocols such as Comet, WebSockets, HTTP CONNECT, HTTP SSH Tunneling etc. are possible implementation options. In the home analogy, a resident receives the parcel from the postal worker by opening the door, however you still take precautions with chain locks and package inspections. Pros: Light weight software, IT doesn't need to setup anything Cons: May bypass critical firewall checks e.g. virus scans, separate software download, proliferation of non-IT managed software Conclusion The patterns above are some of the most commonly encountered ones for cloud to on-premise integration. Selecting the right pattern for your project involves looking at your scalability needs, security restrictions, sync vs asynchronous implementation, near real-time vs batch expectations, cloud provider capabilities, budget, and more. In some cases, the basic "Pull from Cloud" may be acceptable, whereas in others, an extensive VPN topology may be well justified.

2D Particle Explosion

- by TheBroodian

I'm developing a 2D action game, and in said game I've given my primary character an ability he can use to throw a fireball. I'm trying to design an effect so that when said fireball collides (be it with terrain or with an enemy) that the fireball will explode. For the explosion effect I've created a particle that once placed into game space will follow random, yet autonomic behavior based on random variables. Here is my question: When I generate my explosion (essentially 90 of these particles) I get one of two behaviors, 1) They are all generated with the same random variables, and don't resemble an explosion at all, more like a large mass of clumped sprites that all follow the same randomly generated path. 2) If I assign each particle a unique seed to its random number generator, they are a little bit -more- spread out, yet clumping is still visible (they seem to fork out into 3 different directions) Does anybody have any tips for producing particle-based 2D explosions? I'll include the code for my particle and the event I'm generating them in. Fire particle class: public FireParticle(xTile.Dimensions.Location StartLocation, ContentManager content) { worldLocation = StartLocation; fireParticleAnimation = new FireParticleAnimation(content); random = new Random(); int rightorleft = random.Next(0, 3); int upordown = random.Next(1, 3); int xVelocity = random.Next(0, 101); int yVelocity = random.Next(0, 101); Vector2 tempVector2 = new Vector2(0,0); if (rightorleft == 1) { tempVector2 = new Vector2(xVelocity, tempVector2.Y); } else if (rightorleft == 2) { tempVector2 = new Vector2(-xVelocity, tempVector2.Y); } if (upordown == 1) { tempVector2 = new Vector2(tempVector2.X, -yVelocity); } else if (upordown == 2) { tempVector2 = new Vector2(tempVector2.X, yVelocity); } velocity = tempVector2; scale = random.Next(1, 11); upwardForce = -10; dead = false; } public FireParticle(xTile.Dimensions.Location StartLocation, ContentManager content, int seed) { worldLocation = StartLocation; fireParticleAnimation = new FireParticleAnimation(content); random = new Random(seed); int rightorleft = random.Next(0, 3); int upordown = random.Next(1, 3); int xVelocity = random.Next(0, 101); int yVelocity = random.Next(0, 101); Vector2 tempVector2 = new Vector2(0, 0); if (rightorleft == 1) { tempVector2 = new Vector2(xVelocity, tempVector2.Y); } else if (rightorleft == 2) { tempVector2 = new Vector2(-xVelocity, tempVector2.Y); } if (upordown == 1) { tempVector2 = new Vector2(tempVector2.X, -yVelocity); } else if (upordown == 2) { tempVector2 = new Vector2(tempVector2.X, yVelocity); } velocity = tempVector2; scale = random.Next(1, 11); upwardForce = -10; dead = false; } #endregion #region Update and Draw public void Update(GameTime gameTime) { elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; fireParticleAnimation.Update(gameTime); Vector2 moveAmount = velocity * elapsed; xTile.Dimensions.Location newPosition = new xTile.Dimensions.Location(worldLocation.X + (int)moveAmount.X, worldLocation.Y + (int)moveAmount.Y); worldLocation = newPosition; velocity.Y += upwardForce; if (fireParticleAnimation.finishedPlaying) { dead = true; } } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw( fireParticleAnimation.image.Image, new Rectangle((int)drawLocation.X, (int)drawLocation.Y, scale, scale), fireParticleAnimation.image.SizeAndsource, Color.White * fireParticleAnimation.image.Alpha); } Fireball explosion event: public override void Update(GameTime gameTime) { if (enabled) { float elapsed = (float)gameTime.ElapsedGameTime.TotalSeconds; foreach (Heart_of_Fire.World_Objects.Particles.FireParticle particle in explosionParticles.ToList()) { particle.Update(gameTime); if (particle.Dead) { explosionParticles.Remove(particle); } } collisionRectangle = new Microsoft.Xna.Framework.Rectangle((int)wrldPstn.X, (int)wrldPstn.Y, 5, 5); explosionCheck = exploded; if (!exploded) { coreGraphic.Update(gameTime); tailGraphic.Update(gameTime); Vector2 moveAmount = velocity * elapsed; moveAmount = horizontalCollision(moveAmount, layer); moveAmount = verticalCollision(moveAmount, layer); Vector2 newPosition = new Vector2(wrldPstn.X + moveAmount.X, wrldPstn.Y + moveAmount.Y); if (hasCollidedHorizontally || hasCollidedVertically) { exploded = true; } wrldPstn = newPosition; worldLocation = new xTile.Dimensions.Location((int)wrldPstn.X, (int)wrldPstn.Y); } if (explosionCheck != exploded) { for (int i = 0; i < 90; i++) { explosionParticles.Add(new World_Objects.Particles.FireParticle( new Location( collisionRectangle.X + random.Next(0, 6), collisionRectangle.Y + random.Next(0, 6)), contentMgr)); } } if (exploded && explosionParticles.Count() == 0) { //enabled = false; } } }

Right Hand Column Does Not Align Properly in IE6/7/8

- by Kalpesh Vasta

Hi Guys, I'm new to this but here goes. I have been developing this website http://www.panelmaster.co.uk and i have managed to solve the majority of design problems but one! If you take a look at the site in IE the right column seems to drop down and is not aligned with the right and centre column. This problem only occurs in IE as upon testing i found it was fine in firefox and safari. I have provided below the CSS for the website. I would appreciate if you guys can help me with the problem. Thanks in advance. :) ========================== body { margin: 0; padding: 0; line-height: 1.5em; font-family: Tahoma, Geneva, sans-serif; font-size: 12px; color: #666; background-image: url(images/templatemo_body_top.jpg);

Orchard shapeshifting

- by Bertrand Le Roy

I've shown in a previous post how to make it easier to change the layout template for specific contents or areas. But what if you want to change another shape template for specific pages, for example the main Content shape on the home page? Here's how. When we changed the layout, we had the problem that layout is created very early, so early that in fact it can't know what content is going to be rendered. For that reason, we had to rely on a filter and on the routing information to determine what layout template alternates to add. This time around, we are dealing with a content shape, a shape that is directly related to a content item. That makes things a little easier as we have access to a lot more information. What I'm going to do here is handle an event that is triggered every time a shape named "Content" is about to be displayed: public class ContentShapeProvider : IShapeTableProvider { public void Discover(ShapeTableBuilder builder) { builder.Describe("Content") .OnDisplaying(displaying => { // do stuff to the shape }); } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } This handler is implemented in a shape table provider which is where you do all shape related site-wide operations. The first thing we want to do in this event handler is check that we are on the front-end, displaying the "Detail" version, and not the "Summary" or the admin editor: if (displaying.ShapeMetadata.DisplayType == "Detail") { Now I want to provide the ability for the theme developer to provide an alternative template named "Content-HomePage.cshtml" for the home page. In order to determine if we are indeed on the home page I can look at the current site's home page property, which for the default home page provider contains the home page item's id at the end after a semicolon. Compare that with the content item id for the shape we are looking at and you can know if that's the homepage content item. Please note that if that content is also displayed on another page than the home page it will also get the alternate: we are altering at the shape level and not at the URL/routing level like we did with the layout. ContentItem contentItem = displaying.Shape.ContentItem; if (_workContextAccessor.GetContext().CurrentSite .HomePage.EndsWith(';' + contentItem.Id.ToString())) { _workContextAccessor is an injected instance of IWorkContextAccessor from which we can get the current site and its home page. Finally, once we've determined that we are in the specific conditions that we want to alter, we can add the alternate: displaying.ShapeMetadata.Alternates.Add("Content__HomePage"); And that's it really. Here's the full code for the shape provider that I added to a custom theme (but it could really live in any module or theme): using Orchard; using Orchard.ContentManagement; using Orchard.DisplayManagement.Descriptors; namespace CustomLayoutMachine.ShapeProviders { public class ContentShapeProvider : IShapeTableProvider { private readonly IWorkContextAccessor _workContextAccessor; public ContentShapeProvider( IWorkContextAccessor workContextAccessor) { _workContextAccessor = workContextAccessor; } public void Discover(ShapeTableBuilder builder) { builder.Describe("Content") .OnDisplaying(displaying => { if (displaying.ShapeMetadata.DisplayType == "Detail") { ContentItem contentItem = displaying.Shape.ContentItem; if (_workContextAccessor.GetContext() .CurrentSite.HomePage.EndsWith( ';' + contentItem.Id.ToString())) { displaying.ShapeMetadata.Alternates.Add( "Content__HomePage"); } } }); } } } The code for the custom theme, with layout and content alternates, can be downloaded from the following link: Orchard.Themes.CustomLayoutMachine.1.0.nupkg Note: this code is going to be used in the Contoso theme that should be available soon from the theme gallery.

Storing non-content data in Orchard

- by Bertrand Le Roy

A CMS like Orchard is, by definition, designed to store content. What differentiates content from other kinds of data is rather subtle. The way I would describe it is by saying that if you would put each instance of a kind of data on its own web page, if it would make sense to add comments to it, or tags, or ratings, then it is content and you can store it in Orchard using all the convenient composition options that it offers. Otherwise, it probably isn't and you can store it using somewhat simpler means that I will now describe. In one of the modules I wrote, Vandelay.ThemePicker, there is some configuration data for the module. That data is not content by the definition I gave above. Let's look at how this data is stored and queried. The configuration data in question is a set of records, each of which has a number of properties: public class SettingsRecord { public virtual int Id { get; set;} public virtual string RuleType { get; set; } public virtual string Name { get; set; } public virtual string Criterion { get; set; } public virtual string Theme { get; set; } public virtual int Priority { get; set; } public virtual string Zone { get; set; } public virtual string Position { get; set; } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Each property has to be virtual for nHibernate to handle it (it creates derived classed that are instrumented in all kinds of ways). We also have an Id property. The way these records will be stored in the database is described from a migration: public int Create() { SchemaBuilder.CreateTable("SettingsRecord", table => table .Column<int>("Id", column => column.PrimaryKey().Identity()) .Column<string>("RuleType", column => column.NotNull().WithDefault("")) .Column<string>("Name", column => column.NotNull().WithDefault("")) .Column<string>("Criterion", column => column.NotNull().WithDefault("")) .Column<string>("Theme", column => column.NotNull().WithDefault("")) .Column<int>("Priority", column => column.NotNull().WithDefault(10)) .Column<string>("Zone", column => column.NotNull().WithDefault("")) .Column<string>("Position", column => column.NotNull().WithDefault("")) ); return 1; } When we enable the feature, the migration will run, which will create the table in the database. Once we've done that, all we have to do in order to use the data is inject an IRepository<SettingsRecord>, which is what I'm doing from the set of helpers I put under the SettingsService class: private readonly IRepository<SettingsRecord> _repository; private readonly ISignals _signals; private readonly ICacheManager _cacheManager; public SettingsService( IRepository<SettingsRecord> repository, ISignals signals, ICacheManager cacheManager) { _repository = repository; _signals = signals; _cacheManager = cacheManager; } The repository has a Table property, which implements IQueryable<SettingsRecord> (enabling all kind of Linq queries) as well as methods such as Delete and Create. Here's for example how I'm getting all the records in the table: _repository.Table.ToList() And here's how I'm deleting a record: _repository.Delete(_repository.Get(r => r.Id == id)); And here's how I'm creating one: _repository.Create(new SettingsRecord { Name = name, RuleType = ruleType, Criterion = criterion, Theme = theme, Priority = priority, Zone = zone, Position = position }); In summary, you create a record class, a migration, and you're in business and can just manipulate the data through the repository that the framework is exposing. You even get ambient transactions from the work context.

Time to Get Started with Oracle Data Integrator 12c!

- by Sandrine Riley

v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} It is time to get started with Oracle Data Integrator 12c! We would like to highlight for you a great place to begin your journey with ODI. Here you will find the Getting Started section for ODI, which provides a few options. v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} 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-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-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} Step 1 – Start by downloading the Getting Started (PDF). The document provides general background information and detailed examples to help you learn how to use Oracle Data Integrator. This document guides you through a first project with Oracle Data Integrator 12c, and the instructions in this document are required for using the Getting Started Demonstration Environment. If you would like to run the Getting Started Demonstration Environment on your system go to Step 2 A. If you would like to run the Getting Started Demonstration Environment installed and pre-configured in a Virtual Image, go to Step 2 B. Step 2 - A- A - If you would like to run the Getting Started Demo Environment on your system, you will want to then download the Demo Environment for Getting Started (ZIP) archive containing ODI metadata, configuration scripts and sample data. B- B - Alternatively, a pre-configured virtual machine is available with the Getting Started installation and configuration. The Virtual Machine platform uses Oracle Virtual Box technology, and use of this configuration would necessitate the download/installation of Virtual Box and the Getting Started virtual machine. If you prefer this route and would rather run the Getting Started Demonstration Environment installed and preconfigured in a Virtual Machine, please download the ODI 12c Getting Started Virtual Machine. Step 3 – In continuation with the Getting Started Demonstration Environment and the Getting Started Guide, you will now be able to run through a first project with Oracle Data Integrator. Now that you have successfully done the exercises above, you may want to play on your own, and develop with Oracle Data Integrator on your environment... here you can download a full version of Oracle Data Integrator 12c. Enjoy, and happy developing! Learn more about Oracle Data Integrator; including FAQ, the Oracle by Example Series, Sample Code, and White Papers.

From the Classroom to the Boardroom

- by Maria Sandu

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Pens and Paper...these are the only things being a student and being a graduate / professional have in common. Walking in to the offices of Oracle South Africa as a graduate the first thing you notice is how polished and sleek all the people who work here look. 80% of the ladies wear sky-scraper heels and walk with the greatest grace. This was the first of many rude awakenings to remind me that I am no longer a student but a graduate. My first struggle was having to wake up at wee hours of the morning to prepare for work. As a student going to class was almost an optional thing, if you missed a morning class you could always attend an evening class to make up for it or simply attend with another group. But in the workplace, you HAVE to show up every single morning at the same time, with no option of coming in when it suits you and there is definitely no coming in with the evening class/shift. As a student, the earliest hour I ever woke up was 7:00am, anything earlier than that was considered inhumane torture. My reason for waking up every morning as a student was “you have a degree to go get” but as a graduate having to go to work I have to say to myself “here’s to a new day of learning and growing”. My second struggle has come in having to change my beloved wardrobe. Everyone who knows me knows how passionate I am about fashion and shopping. For me Shopping is a BASIC HUMAN RIGHT, that should not be messed with. Therefore it was with great sadness that I swopped my rippled skinny jeans for pin-striped formal pants, my long chandelier earrings for simple studs, my flat shoes for heels, my sheer blouses for crisp white shirts, even my beloved wild hair had to make way for a simple ponytail. Our looks as ladies also came under great scrutiny, we had to acquaint ourselves with some serious grooming tools: the mascara, blush, lip-gloss, blush, a touch of lipstick and a manicure set. Language was a struggle of its own as well. Being a student you learn to relate to your peers in a informal way. In the workplace you have to address everyone with the same respect, including your peers. Words like “Hey buddy” had to make way for “good morning friend”. The month long winter school holiday was one of the things I looked forward to as a student. This was a time where we got to be at home and avoid the coldest month of the year, July. It was the most amazing thing ever, just sleeping and snuggling up to all sorts of warm things but sadly it is now a thing of the past. It is currently winter in South Africa and going to work has become the most unfashionable thing with all the jackets, boots, scarves and gloves. But summer is coming and I will miss those holidays too. As a student the school holidays were like a gift for us to catch a break and not think for a while which was why it was imaginable how someone would go on for the entire year without a break, with only the promise of a mere 21 days annual leave!! Right now I am sure we are all looking forward to taking that annual leave when the time is right. The worst rude awakening I must say, has to be presenting in front of clients and managers. As a student you have the same class mates for almost four years therefore presenting in front of them becomes the norm over the years and your lecturer will always go gently on you. What they don’t tell you at University is that in the real world, time is money and clients pay money to see you present therefore there is no room for error. Clients are not there to give you a score and boost your ego, they expect nothing less than 100% and they will let you know without a second thought. For a graduate this can feel like you are being fed to the sharks, you either get eaten or you swim for your life. At the end of the day, it is all an experience that is meant to groom us into better professional and make us a part of the Red Team. All the sacrifices are worth it and they lead us to being better and more polished professionals.

Grub won't boot windows after update from 11.10 to 12.04

- by Holger

thanks for your time and reading this, here's the deal: i upgraded from 11.10 to 12.04 and everything worked out until i rebooted, i had 11.10 sucessfully running as a dual boot with windows vista. when i rebooted, my GRUB was shot to hell, what ever option i selected it said partion not found or something similar... booting into a live version on a thumb drive and running bootrepair from there fixed the issue... but only for ubuntu, when i try to boot into windows it only goes back to GRUB. i'm not at home, and heres a list of what i have here with me... 1 4gb thumb drive, empty 1 8gb thumb drive, windows vista installer bootable 1 old laptop, the one i try to save, optical drive is not existent 2 Mbps internet connection can you help me get back into my windows without having to reinstall windows? or at least show me a way how to use my illustrator through a virtual machine or something? here's my grub cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ];

Why is my animation getting aborted?

- by Homer_Simpson

I have a class named Animation which handles my animations. The animation class can be called from multiple other classes. For example, the class Player.cs can call the animation class like this: Animation Playeranimation; Playeranimation = new Animation(TimeSpan.FromSeconds(2.5f), 80, 40, Animation.Sequences.forwards, 0, 5, false, true); //updating the animation public void Update(GameTime gametime) { Playeranimation.Update(gametime); } //drawing the animation public void Draw(SpriteBatch batch) { playeranimation.Draw(batch, PlayerAnimationSpritesheet, PosX, PosY, 0, SpriteEffects.None); } The class Lion.cs can call the animation class with the same code, only the animation parameters are changing because it's another animation that should be played: Animation Lionanimation; Lionanimation = new Animation(TimeSpan.FromSeconds(2.5f), 100, 60, Animation.Sequences.forwards, 0, 8, false, true); Other classes can call the animation class with the same code like the Player class. But sometimes I have some trouble with the animations. If an animation is running and then shortly afterwards another class calls the animation class too, the second animation starts but the first animation is getting aborted. In this case, the first animation couldn't run until it's end because another class started a new instance of the animation class. Why is an animation sometimes getting aborted when another animation starts? How can I solve this problem? My animation class: public class Animation { private int _animIndex, framewidth, frameheight, start, end; private TimeSpan PassedTime; private List<Rectangle> SourceRects = new List<Rectangle>(); private TimeSpan Duration; private Sequences Sequence; public bool Remove; private bool DeleteAfterOneIteration; public enum Sequences { forwards, backwards, forwards_backwards, backwards_forwards } private void forwards() { for (int i = start; i < end; i++) SourceRects.Add(new Rectangle(i * framewidth, 0, framewidth, frameheight)); } private void backwards() { for (int i = start; i < end; i++) SourceRects.Add(new Rectangle((end - 1 - i) * framewidth, 0, framewidth, frameheight)); } private void forwards_backwards() { for (int i = start; i < end - 1; i++) SourceRects.Add(new Rectangle(i * framewidth, 0, framewidth, frameheight)); for (int i = start; i < end; i++) SourceRects.Add(new Rectangle((end - 1 - i) * framewidth, 0, framewidth, frameheight)); } private void backwards_forwards() { for (int i = start; i < end - 1; i++) SourceRects.Add(new Rectangle((end - 1 - i) * framewidth, 0, framewidth, frameheight)); for (int i = start; i < end; i++) SourceRects.Add(new Rectangle(i * framewidth, 0, framewidth, frameheight)); } public Animation(TimeSpan duration, int frame_width, int frame_height, Sequences sequences, int start_interval, int end_interval, bool remove, bool deleteafteroneiteration) { Remove = remove; DeleteAfterOneIteration = deleteafteroneiteration; framewidth = frame_width; frameheight = frame_height; start = start_interval; end = end_interval; switch (sequences) { case Sequences.forwards: { forwards(); break; } case Sequences.backwards: { backwards(); break; } case Sequences.forwards_backwards: { forwards_backwards(); break; } case Sequences.backwards_forwards: { backwards_forwards(); break; } } Duration = duration; Sequence = sequences; } public void Update(GameTime dt) { PassedTime += dt.ElapsedGameTime; if (PassedTime > Duration) { PassedTime -= Duration; } var percent = PassedTime.TotalSeconds / Duration.TotalSeconds; if (DeleteAfterOneIteration == true) { if (_animIndex >= SourceRects.Count) Remove = true; _animIndex = (int)Math.Round(percent * (SourceRects.Count)); } else { _animIndex = (int)Math.Round(percent * (SourceRects.Count - 1)); } } public void Draw(SpriteBatch batch, Texture2D Textures, float PositionX, float PositionY, float Rotation, SpriteEffects Flip) { if (DeleteAfterOneIteration == true) { if (_animIndex >= SourceRects.Count) return; } batch.Draw(Textures, new Rectangle((int)PositionX, (int)PositionY, framewidth, frameheight), SourceRects[_animIndex], Color.White, Rotation, new Vector2(framewidth / 2.0f, frameheight / 2.0f), Flip, 0f); } }

Trying to use json to populate areas of my website using mysql, php, and jquery.

- by RyanPitts

Ok, so this is my first attempt at doing anything with JSON. I have done a lot with PHP and MySql as well as jQuery and JavaScript...but nothing with JSON. I have some data in a MySql database. In the codes below i am using a PHP file to retrieve the data from the MySql database and using json_encode to format it to JSON. This file is being called by the JavaScript that runs when the page loads (well, it runs on document.ready actually). I then use jQuery to access the JSON keys and values to fill in areas of the page "dynamically". Here is the code snippets i am using (excuse my "noobness" on writing these snippets, still learning all this). This is my script that is on my HTML page test.php: <script type="text/javascript"> $(document).ready(function(){ $.getJSON("json_events.php",function(data){ $.each(data.events, function(i,events){ var tblRow = "<tr>" +"<td>" + events.id + "</td>" +"<td>" + events.customerId + "</td>" +"<td>" + events.filingName + "</td>" +"<td>" + events.title + "</td>" +"<td>" + events.details + "</td>" +"<td>" + events.dateEvent + "</td>" +"<td><a href='assets/customers/testchurch/events/" + events.image + "'>" + events.image + "</a></td>" +"<td>" + events.dateStart + "</td>" +"<td>" + events.dateEnd + "</td>" +"</tr>" $(tblRow).appendTo("#eventsdata tbody"); }); }); $.getJSON("json_events.php",function(data){ $.each(data.events, function(i,events){ $("#title").html("First event title: " + events.title + " ..."); }); }); }); </script> This is the code for the php file being called by the above JS: json_events.php <?php require_once('includes/configread.php'); $arrayEvents = array(); $resultsEvents = mysql_query("SELECT * FROM events"); while($objectEvents = mysql_fetch_object($resultsEvents)) { $arrayEvents[] = $objectEvents; } $json_object_events = json_encode($arrayEvents); $json_events = "{\"events\": " . $json_object_events . " }"; echo $json_events; require_once('includes/closeconnread.php'); ?> This is my JSON that is held in the variable $json_events from my php file json_events.php: { "events": [ { "id": "2", "customerId": "1004", "filingName": "testchurch", "title": "Kenya 2011 Training Meeting", "details": "This meeting will be taking place on Sunday, February 10th @ 6pm. Get ready for our annual Kenya trip in 2011. We have been blessed to be able to take this trip for the past 3 years. Now, it's your turn to bless others! Come to this training meeting to learn how to minister to the people in Kenya and also learn what we'll be doing there.", "dateEvent": "2011-02-10", "image": "kenya2011.jpg", "dateStart": "2010-09-04", "dateEnd": "2011-02-10" }, { "id": "6", "customerId": "1004", "filingName": "testchurch", "title": "New Series: The Journey", "details": "We will be starting our new series titled "The Journey". Come worship with us as we walk with Paul on his 2nd missionary journey.", "dateEvent": "2011-01-02", "image": "", "dateStart": "2010-09-06", "dateEnd": "2011-01-02" } ] } This is my HTML on test.php: <table id="eventsdata" border="1"> <thead> <tr> <th>id</th> <th>customerId</th> <th>filingName</th> <th>title</th> <th>details</th> <th>dateEvent</th> <th>image</th> <th>dateStart</th> <th>dateEnd</th> </tr> </thead> <tbody></tbody> </table> <div id="title"></div> I have two questions really... Question 1: Does this code look like it is written correctly at first glance? Question 2: I want to be able to select only the title from the first event in the JSON array. The code i am using now is selecting the second events' title by default it seems. How can i accomplish this?

Why is Java EE 6 better than Spring ?

- by arungupta

Java EE 6 was released over 2 years ago and now there are 14 compliant application servers. In all my talks around the world, a question that is frequently asked is Why should I use Java EE 6 instead of Spring ? There are already several blogs covering that topic: Java EE wins over Spring by Bill Burke Why will I use Java EE instead of Spring in new Enterprise Java projects in 2012 ? by Kai Waehner (more discussion on TSS) Spring to Java EE migration (Part 1 and 2, 3 and 4 coming as well) by David Heffelfinger Spring to Java EE - A Migration Experience by Lincoln Baxter Migrating Spring to Java EE 6 by Bert Ertman and Paul Bakker at NLJUG Moving from Spring to Java EE 6 - The Age of Frameworks is Over at TSS Java EE vs Spring Shootout by Rohit Kelapure and Reza Rehman at JavaOne 2011 Java EE 6 and the Ewoks by Murat Yener Definite excuse to avoid Spring forever - Bert Ertman and Arun Gupta I will try to share my perspective in this blog. First of all, I'd like to start with a note: Thank you Spring framework for filling the interim gap and providing functionality that is now included in the mainstream Java EE 6 application servers. The Java EE platform has evolved over the years learning from frameworks like Spring and provides all the functionality to build an enterprise application. Thank you very much Spring framework! While Spring was revolutionary in its time and is still very popular and quite main stream in the same way Struts was circa 2003, it really is last generation's framework - some people are even calling it legacy. However my theory is "code is king". So my approach is to build/take a simple Hello World CRUD application in Java EE 6 and Spring and compare the deployable artifacts. I started looking at the official tutorial Developing a Spring Framework MVC Application Step-by-Step but it is using the older version 2.5. I wasn't able to find any updated version in the current 3.1 release. Next, I downloaded Spring Tool Suite and thought that would provide some template samples to get started. A least a quick search did not show any handy tutorials - either video or text-based. So I searched and found a link to their SVN repository at src.springframework.org/svn/spring-samples/. I tried the "mvc-basic" sample and the generated WAR file was 4.43 MB. While it was named a "basic" sample it seemed to come with 19 different libraries bundled but it was what I could find: ./WEB-INF/lib/aopalliance-1.0.jar./WEB-INF/lib/hibernate-validator-4.1.0.Final.jar./WEB-INF/lib/jcl-over-slf4j-1.6.1.jar./WEB-INF/lib/joda-time-1.6.2.jar./WEB-INF/lib/joda-time-jsptags-1.0.2.jar./WEB-INF/lib/jstl-1.2.jar./WEB-INF/lib/log4j-1.2.16.jar./WEB-INF/lib/slf4j-api-1.6.1.jar./WEB-INF/lib/slf4j-log4j12-1.6.1.jar./WEB-INF/lib/spring-aop-3.0.5.RELEASE.jar./WEB-INF/lib/spring-asm-3.0.5.RELEASE.jar./WEB-INF/lib/spring-beans-3.0.5.RELEASE.jar./WEB-INF/lib/spring-context-3.0.5.RELEASE.jar./WEB-INF/lib/spring-context-support-3.0.5.RELEASE.jar./WEB-INF/lib/spring-core-3.0.5.RELEASE.jar./WEB-INF/lib/spring-expression-3.0.5.RELEASE.jar./WEB-INF/lib/spring-web-3.0.5.RELEASE.jar./WEB-INF/lib/spring-webmvc-3.0.5.RELEASE.jar./WEB-INF/lib/validation-api-1.0.0.GA.jar And it is not even using any database! The app deployed fine on GlassFish 3.1.2 but the "@Controller Example" link did not work as it was missing the context root. With a bit of tweaking I could deploy the application and assume that the account got created because no error was displayed in the browser or server log. Next I generated the WAR for "mvc-ajax" and the 5.1 MB WAR had 20 JARs (1 removed, 2 added): ./WEB-INF/lib/aopalliance-1.0.jar./WEB-INF/lib/hibernate-validator-4.1.0.Final.jar./WEB-INF/lib/jackson-core-asl-1.6.4.jar./WEB-INF/lib/jackson-mapper-asl-1.6.4.jar./WEB-INF/lib/jcl-over-slf4j-1.6.1.jar./WEB-INF/lib/joda-time-1.6.2.jar./WEB-INF/lib/jstl-1.2.jar./WEB-INF/lib/log4j-1.2.16.jar./WEB-INF/lib/slf4j-api-1.6.1.jar./WEB-INF/lib/slf4j-log4j12-1.6.1.jar./WEB-INF/lib/spring-aop-3.0.5.RELEASE.jar./WEB-INF/lib/spring-asm-3.0.5.RELEASE.jar./WEB-INF/lib/spring-beans-3.0.5.RELEASE.jar./WEB-INF/lib/spring-context-3.0.5.RELEASE.jar./WEB-INF/lib/spring-context-support-3.0.5.RELEASE.jar./WEB-INF/lib/spring-core-3.0.5.RELEASE.jar./WEB-INF/lib/spring-expression-3.0.5.RELEASE.jar./WEB-INF/lib/spring-web-3.0.5.RELEASE.jar./WEB-INF/lib/spring-webmvc-3.0.5.RELEASE.jar./WEB-INF/lib/validation-api-1.0.0.GA.jar 2 more JARs for just doing Ajax. Anyway, deploying this application gave the following error: Caused by: java.lang.NoSuchMethodError: org.codehaus.jackson.map.SerializationConfig.<init>(Lorg/codehaus/jackson/map/ClassIntrospector;Lorg/codehaus/jackson/map/AnnotationIntrospector;Lorg/codehaus/jackson/map/introspect/VisibilityChecker;Lorg/codehaus/jackson/map/jsontype/SubtypeResolver;)V at org.springframework.samples.mvc.ajax.json.ConversionServiceAwareObjectMapper.<init>(ConversionServiceAwareObjectMapper.java:20) at org.springframework.samples.mvc.ajax.json.JacksonConversionServiceConfigurer.postProcessAfterInitialization(JacksonConversionServiceConfigurer.java:40) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsAfterInitialization(AbstractAutowireCapableBeanFactory.java:407) Seems like some incorrect repos in the "pom.xml". Next one is "mvc-showcase" and the 6.49 MB WAR now has 28 JARs as shown below: ./WEB-INF/lib/aopalliance-1.0.jar./WEB-INF/lib/aspectjrt-1.6.10.jar./WEB-INF/lib/commons-fileupload-1.2.2.jar./WEB-INF/lib/commons-io-2.0.1.jar./WEB-INF/lib/el-api-2.2.jar./WEB-INF/lib/hibernate-validator-4.1.0.Final.jar./WEB-INF/lib/jackson-core-asl-1.8.1.jar./WEB-INF/lib/jackson-mapper-asl-1.8.1.jar./WEB-INF/lib/javax.inject-1.jar./WEB-INF/lib/jcl-over-slf4j-1.6.1.jar./WEB-INF/lib/jdom-1.0.jar./WEB-INF/lib/joda-time-1.6.2.jar./WEB-INF/lib/jstl-api-1.2.jar./WEB-INF/lib/jstl-impl-1.2.jar./WEB-INF/lib/log4j-1.2.16.jar./WEB-INF/lib/rome-1.0.0.jar./WEB-INF/lib/slf4j-api-1.6.1.jar./WEB-INF/lib/slf4j-log4j12-1.6.1.jar./WEB-INF/lib/spring-aop-3.1.0.RELEASE.jar./WEB-INF/lib/spring-asm-3.1.0.RELEASE.jar./WEB-INF/lib/spring-beans-3.1.0.RELEASE.jar./WEB-INF/lib/spring-context-3.1.0.RELEASE.jar./WEB-INF/lib/spring-context-support-3.1.0.RELEASE.jar./WEB-INF/lib/spring-core-3.1.0.RELEASE.jar./WEB-INF/lib/spring-expression-3.1.0.RELEASE.jar./WEB-INF/lib/spring-web-3.1.0.RELEASE.jar./WEB-INF/lib/spring-webmvc-3.1.0.RELEASE.jar./WEB-INF/lib/validation-api-1.0.0.GA.jar The app at least deployed and showed results this time. But still no database! Next I tried building "jpetstore" and got the error: [ERROR] Failed to execute goal on project org.springframework.samples.jpetstore:Could not resolve dependencies for project org.springframework.samples:org.springframework.samples.jpetstore:war:1.0.0-SNAPSHOT: Failed to collect dependencies for [commons-fileupload:commons-fileupload:jar:1.2.1 (compile), org.apache.struts:com.springsource.org.apache.struts:jar:1.2.9 (compile), javax.xml.rpc:com.springsource.javax.xml.rpc:jar:1.1.0 (compile), org.apache.commons:com.springsource.org.apache.commons.dbcp:jar:1.2.2.osgi (compile), commons-io:commons-io:jar:1.3.2 (compile), hsqldb:hsqldb:jar:1.8.0.7 (compile), org.apache.tiles:tiles-core:jar:2.2.0 (compile), org.apache.tiles:tiles-jsp:jar:2.2.0 (compile), org.tuckey:urlrewritefilter:jar:3.1.0 (compile), org.springframework:spring-webmvc:jar:3.0.0.BUILD-SNAPSHOT (compile), org.springframework:spring-orm:jar:3.0.0.BUILD-SNAPSHOT (compile), org.springframework:spring-context-support:jar:3.0.0.BUILD-SNAPSHOT (compile), org.springframework.webflow:spring-js:jar:2.0.7.RELEASE (compile), org.apache.ibatis:com.springsource.com.ibatis:jar:2.3.4.726 (runtime), com.caucho:com.springsource.com.caucho:jar:3.2.1 (compile), org.apache.axis:com.springsource.org.apache.axis:jar:1.4.0 (compile), javax.wsdl:com.springsource.javax.wsdl:jar:1.6.1 (compile), javax.servlet:jstl:jar:1.2 (runtime), org.aspectj:aspectjweaver:jar:1.6.5 (compile), javax.servlet:servlet-api:jar:2.5 (provided), javax.servlet.jsp:jsp-api:jar:2.1 (provided), junit:junit:jar:4.6 (test)]: Failed to read artifact descriptor for org.springframework:spring-webmvc:jar:3.0.0.BUILD-SNAPSHOT: Could not transfer artifact org.springframework:spring-webmvc:pom:3.0.0.BUILD-SNAPSHOT from/to JBoss repository (http://repository.jboss.com/maven2): Access denied to: http://repository.jboss.com/maven2/org/springframework/spring-webmvc/3.0.0.BUILD-SNAPSHOT/spring-webmvc-3.0.0.BUILD-SNAPSHOT.pom It appears the sample is broken - maybe I was pulling from the wrong repository - would be great if someone were to point me at a good target to use here. With a 50% hit on samples in this repository, I started searching through numerous blogs, most of which have either outdated information (using XML-heavy Spring 2.5), some piece of configuration (which is a typical "feature" of Spring) is missing, or too much complexity in the sample. I finally found this blog that worked like a charm. This blog creates a trivial Spring MVC 3 application using Hibernate and MySQL. This application performs CRUD operations on a single table in a database using typical Spring technologies. I downloaded the sample code from the blog, deployed it on GlassFish 3.1.2 and could CRUD the "person" entity. The source code for this application can be downloaded here. More details on the application statistics below. And then I built a similar CRUD application in Java EE 6 using NetBeans wizards in a couple of minutes. The source code for the application can be downloaded here and the WAR here. The Spring Source Tool Suite may also offer similar wizard-driven capabilities but this blog focus primarily on comparing the runtimes. The lack of STS tutorials was slightly disappointing as well. NetBeans however has tons of text-based and video tutorials and tons of material even by the community. One more bit on the download size of tools bundle ... NetBeans 7.1.1 "All" is 211 MB (which includes GlassFish and Tomcat) Spring Tool Suite 2.9.0 is 347 MB (~ 65% bigger) This blog is not about the tooling comparison so back to the Java EE 6 version of the application .... In order to run the Java EE version on GlassFish, copy the MySQL Connector/J to glassfish3/glassfish/domains/domain1/lib/ext directory and create a JDBC connection pool and JDBC resource as: ./bin/asadmin create-jdbc-connection-pool --datasourceclassname \\ com.mysql.jdbc.jdbc2.optional.MysqlDataSource --restype \\ javax.sql.DataSource --property \\ portNumber=3306:user=mysql:password=mysql:databaseName=mydatabase \\ myConnectionPool ./bin/asadmin create-jdbc-resource --connectionpoolid myConnectionPool jdbc/myDataSource I generated WARs for the two projects and the table below highlights some differences between them: Java EE 6 Spring WAR File Size 0.021030 MB 10.87 MB (~516x) Number of files 20 53 (> 2.5x) Bundled libraries 0 36 Total size of libraries 0 12.1 MB XML files 3 5 LoC in XML files 50 (11 + 15 + 24) 129 (27 + 46 + 16 + 11 + 19) (~ 2.5x) Total .properties files 1 Bundle.properties 2 spring.properties, log4j.properties Cold Deploy 5,339 ms 11,724 ms Second Deploy 481 ms 6,261 ms Third Deploy 528 ms 5,484 ms Fourth Deploy 484 ms 5,576 ms Runtime memory ~73 MB ~101 MB Some points worth highlighting from the table ... 516x WAR file, 10x deployment time - With 12.1 MB of libraries (for a very basic application) bundled in your application, the WAR file size and the deployment time will naturally go higher. The WAR file for Spring-based application is 516x bigger and the deployment time is double during the first deployment and ~ 10x during subsequent deployments. The Java EE 6 application is fully portable and will run on any Java EE 6 compliant application server. 36 libraries in the WAR - There are 14 Java EE 6 compliant application servers today. Each of those servers provide all the functionality like transactions, dependency injection, security, persistence, etc typically required of an enterprise or web application. There is no need to bundle 36 libraries worth 12.1 MB for a trivial CRUD application. These 14 compliant application servers provide all the functionality baked in. Now you can also deploy these libraries in the container but then you don't get the "portability" offered by Spring in that case. Does your typical Spring deployment actually do that ? 3x LoC in XML - The number of XML files is about 1.6x and the LoC is ~ 2.5x. So much XML seems circa 2003 when the Java language had no annotations. The XML files can be further reduced, e.g. faces-config.xml can be replaced without providing i18n, but I just want to compare stock applications. Memory usage - Both the applications were deployed on default GlassFish 3.1.2 installation and any additional memory consumed as part of deployment/access was attributed to the application. This is by no means scientific but at least provides an initial ballpark. This area definitely needs more investigation. Another table that compares typical Java EE 6 compliant application servers and the custom-stack created for a Spring application ... Java EE 6 Spring Web Container ? 53 MB (tcServer 2.6.3 Developer Edition) Security ? 12 MB (Spring Security 3.1.0) Persistence ? 6.3 MB (Hibernate 4.1.0, required) Dependency Injection ? 5.3 MB (Framework) Web Services ? 796 KB (Spring WS 2.0.4) Messaging ? 3.4 MB (RabbitMQ Server 2.7.1) 936 KB (Java client 936) OSGi ? 1.3 MB (Spring OSGi 1.2.1) GlassFish and WebLogic (starting at 33 MB) 83.3 MB There are differentiating factors on both the stacks. But most of the functionality like security, persistence, and dependency injection is baked in a Java EE 6 compliant application server but needs to be individually managed and patched for a Spring application. This very quickly leads to a "stack explosion". The Java EE 6 servers are tested extensively on a variety of platforms in different combinations whereas a Spring application developer is responsible for testing with different JDKs, Operating Systems, Versions, Patches, etc. Oracle has both the leading OSS lightweight server with GlassFish and the leading enterprise Java server with WebLogic Server, both Java EE 6 and both with lightweight deployment options. The Web Container offered as part of a Java EE 6 application server not only deploys your enterprise Java applications but also provide operational management, diagnostics, and mission-critical capabilities required by your applications. The Java EE 6 platform also introduced the Web Profile which is a subset of the specifications from the entire platform. It is targeted at developers of modern web applications offering a reasonably complete stack, composed of standard APIs, and is capable out-of-the-box of addressing the needs of a large class of Web applications. As your applications grow, the stack can grow to the full Java EE 6 platform. The GlassFish Server Web Profile starting at 33MB (smaller than just the non-standard tcServer) provides most of the functionality typically required by a web application. WebLogic provides battle-tested functionality for a high throughput, low latency, and enterprise grade web application. No individual managing or patching, all tested and commercially supported for you! Note that VMWare does have a server, tcServer, but it is non-standard and not even certified to the level of the standard Web Profile most customers expect these days. Customers who choose this risk proprietary lock-in since VMWare does not seem to want to formally certify with either Java EE 6 Enterprise Platform or with Java EE 6 Web Profile but of course it would be great if they were to join the community and help their customers reduce the risk of deploying on VMWare software. Some more points to help you decide choose between Java EE 6 and Spring ... Freedom to choose container - There are 14 Java EE 6 compliant application servers today, with a variety of open source and commercial offerings. A Java EE 6 application can be deployed on any of those containers. So if you deployed your application on GlassFish today and would like to scale up with your demands then you can deploy the same application to WebLogic. And because of the portability of a Java EE 6 application, you can even take it a different vendor altogether. Spring requires a runtime which could be any of these app servers as well. But why use Spring when all the required functionality is already baked into the application server itself ? Spring also has a different definition of portability where they claim to bundle all the libraries in the WAR file and move to any application server. But we saw earlier how bloated that archive could be. The equivalent features in Spring runtime offerings (mainly tcServer) are not all open source, not as mature, and often require manual assembly. Vendor choice - The Java EE 6 platform is created using the Java Community Process where all the big players like Oracle, IBM, RedHat, and Apache are conritbuting to make the platform successful. Each application server provides the basic Java EE 6 platform compliance and has its own competitive offerings. This allows you to choose an application server for deploying your Java EE 6 applications. If you are not happy with the support or feature of one vendor then you can move your application to a different vendor because of the portability promise offered by the platform. Spring is a set of products from a single company, one price book, one support organization, one sustaining organization, one sales organization, etc. If any of those cause a customer headache, where do you go ? Java EE, backed by multiple vendors, is a safer bet for those that are risk averse. Production support - With Spring, typically you need to get support from two vendors - VMWare and the container provider. With Java EE 6, all of this is typically provided by one vendor. For example, Oracle offers commercial support from systems, operating systems, JDK, application server, and applications on top of them. VMWare certainly offers complete production support but do you really want to put all your eggs in one basket ? Do you really use tcServer ? ;-) Maintainability - With Spring, you are likely building your own distribution with multiple JAR files, integrating, patching, versioning, etc of all those components. Spring's claim is that multiple JAR files allow you to go à la carte and pick the latest versions of different components. But who is responsible for testing whether all these versions work together ? Yep, you got it, its YOU! If something does not work, who patches and maintains the JARs ? Of course, you! Commercial support for such a configuration ? On your own! The Java EE application servers manage all of this for you and provide a well-tested and commercially supported bundle. While it is always good to realize that there is something new and improved that updates and replaces older frameworks like Spring, the good news is not only does a Java EE 6 container offer what is described here, most also will let you deploy and run your Spring applications on them while you go through an upgrade to a more modern architecture. End result, you get the best of both worlds - keeping your legacy investment but moving to a more agile, lightweight world of Java EE 6. A message to the Spring lovers ... The complexity in J2EE 1.2, 1.3, and 1.4 led to the genesis of Spring but that was in 2004. This is 2012 and the name has changed to "Java EE 6" :-) There are tons of improvements in the Java EE platform to make it easy-to-use and powerful. Some examples: Adding @Stateless on a POJO makes it an EJB EJBs can be packaged in a WAR with no special packaging or deployment descriptors "web.xml" and "faces-config.xml" are optional in most of the common cases Typesafe dependency injection is now part of the Java EE platform Add @Path on a POJO allows you to publish it as a RESTful resource EJBs can be used as backing beans for Facelets-driven JSF pages providing full MVC Java EE 6 WARs are known to be kilobytes in size and deployed in milliseconds Tons of other simplifications in the platform and application servers So if you moved away from J2EE to Spring many years ago and have not looked at Java EE 6 (which has been out since Dec 2009) then you should definitely try it out. Just be at least aware of what other alternatives are available instead of restricting yourself to one stack. Here are some workshops and screencasts worth trying: screencast #37 shows how to build an end-to-end application using NetBeans screencast #36 builds the same application using Eclipse javaee-lab-feb2012.pdf is a 3-4 hours self-paced hands-on workshop that guides you to build a comprehensive Java EE 6 application using NetBeans Each city generally has a "spring cleanup" program every year. It allows you to clean up the mess from your house. For your software projects, you don't need to wait for an annual event, just get started and reduce the technical debt now! Move away from your legacy Spring-based applications to a lighter and more modern approach of building enterprise Java applications using Java EE 6.

Server Admin is not allowing me to configure DNS

- by Clinton Blackmore

We have a Mac OS X 10.5.8 Server running DNS (and a few other services). When I connect to it (using Server Admin 10.5.3 [which comes from the Server Admin 10.5.7 tools]), and click to look at the DNS settings, all appears normal -- it shows many reverse entries and two top-level domains. However, when I select one of our domains and open the disclosure triangle, the list is empty! [There should be over a dozen entries, and the reverse entries do show up.] If I then tell it I want to add, say, an A Record to the domain, almost everything disappears -- and I am left with a list showing our two domains, one with a disclosure triangle underneath it showing a single entry, and one reverse entry to correspond to the new A record. named appears to be working fine. DNS names resolve. It appears to simply be that Server Admin is having problems with the data on the computer. No one here would have manually created a DNS entry. Now, while I think I've backed up the DNS (I backed up /var/named/, /etc/named.conf, and /etc/dns/, as mentioned here), I'm really not sure if just replacing the files would restore the DNS settings we have if things go south. I am contemplating going to settings and changing the log level from "Information" to "Debug", but 1) I am just a little concerned that it might write a bad configuration to the disk, and 2) I think it would only affect named and not Server Admin, and, so far as I can tell, named is not having a problem. (Nothing looks strange in /Library/Logs/named.log when I open it via Console/Terminal. Oddly, though, when I click on the 'log' button for DNS in Server Admin, I see no text at all, just a fully white window. When I look at one of our secondary DNS servers, I am able to see the log file through Server Admin.) This entry appears in the system log when I run Server Admin on the server: Jun 17 09:02:08 od1 Server Admin[3892]: Unexpected call to doMarkConfigurationAsDirty by 'DNS' plugin during updateConfigurationViewFromDescription It seems to occur after I've looked at DNS, look at another service, and then click back on DNS. Think that the most likely cause is a corrupt configuration file, I glanced through all the files that I backed up, and none of them is obviously gobbledygook. Here are some oddities I find when running Server Admin from a remote computer to manage the DNS. When I click to see the log file for DNS, the server starts writing messages like these to its system.log: Jun 17 09:59:04 od1 kernel[0]: Limiting open port RST response from 252 to 250 packets per second Jun 17 09:59:06 od1 kernel[0]: Limiting open port RST response from 258 to 250 packets per second This stops when I click on a different service. The inderterminate progress indicator (the spinning wheel that appears beside the "Revert" and "Save" buttons in the bottom-right corner of Server Admin) looks really strange. As far as I can tell, instead of just spinning and waiting, it is being told to start spinning repeatedly, resulting in a jerky animation. Here are some of the messages being logged on the computer running Server Admin: At startup: *** ERROR: -[GRAxes computeLayout]:1124 - plotRect height = 0.000000 <= 0.0 *** *** ERROR: -[GRChartView computeLayout]:1194 - Layout for overlay axes (0x18758f50) failed. *** (These messages don't concern me too much as they go away for a while if you delete ~/Library/Preferences/com.apple.ServerAdmin.plist). At shutdown: 2010-06-17 10:02:17.202 Server Admin[7770:10b] *** -[GroupTextField windowDidResignKey:]: unrecognized selector sent to instance 0x16e12490 More concerning are these messages: 2010-06-17 09:59:47.269 Server Admin[7770:10b] Unexpected call to doMarkConfigurationAsDirty by 'DNS' plugin during updateConfigurationViewFromDescription Server Admin(7770,0xb0453000) malloc: *** error for object 0x1c115390: double free *** set a breakpoint in malloc_error_break to debug 2010-06-17 10:01:00.795 Server Admin[7770:10b] *** -[ServiceEntry sessionHost]: unrecognized selector sent to instance 0x2af500 Any thoughts on: what the problem is how I can troubleshoot it or how to fix it? If I do need to wipe out DNS and restart, is there a good way to do this?

Accessing resources on localhost using domain credentials

- by jas

I'm trying to set up Team Foundation Server 2010, Sharepoint Server 2010 and Report Server 2008R2. I apologize for how long my question/problem is but I'm really lost on where to even look so am being as descriptive as possible in hopes that I'm making sense. The goal: Since developers can be inside or outside the firewall there needs to be a single http point of entry to TFS that works regardless of which side of the firewall you are and needs to work with external access to SharePoint and Report Server. Meaning we have it set up in DNS so buildserver.mydomain.com: points to the build service box which contains all of the services listed at the top of this post and specific services are defined/located by the port number. This is working great on every machine inside and out except for from the build server itself. All services must be able to work using external URLs. If I use http:// buildserver.mydomain.com:4800/tfs (the external URL) from my notebook which is behind the firewall I'm able to login with my domain credentials as expected. If the other developer points to the same URL from their home which isn't on the domain they are also able to login using their domain credentials. However if I am directly on buildserver and call SharePoint, TFS or Reporting Server from (i.e. http:// buildserver.mydomain.com:4800) itself using the external URL, I am prompted for a username and password. Entering my domain credentials results in another prompt to enter my credentials again. It will prompt three times regardless of which credentials are used (I have rights as a domain admin) and then after the third prompt directs me to a blank white page as though access was denied. There are no errors displayed on the page and nothing ends up in the event viewer. From buildserver if i use just the host name (the internal URL), then I'm prompted a single time for credentials and it works. i.e. http:// buildserver:4800/tfs works from the server itself. The behavior is identical for any service requiring authentication. Meaning from the box itself Sharepoint Central Admin, SharePoint WebApp, TFS, TFS Web Access, Report Server and Report Manager all fail using the external URL but will succeed if called using the interal URL. So the problem comes into play when configuring all of the services to work together. The only way to configure TFS is locally from the server which means I must point to the internal reporting server url (http:// buildserver:4800/reports and reportServer respectively instead of http:// buildserver.domainname.com:4800 like they need to be) since external URLs aren't working from itself. If I configure TFS to use the internal URL for Report Server then creating team projects or working in the SharePoint site for the team project fails for anyone not inside the domain since their machines have no idea who http:// buildserver:/reports even is or how to resolve them. I have configured Sharepoint with Alternate Access Mappings as well as set up Report Server to listen for external URLs. The external URLs simply aren't working when called from the server itself. I hope this makes sense. Thanks for taking the time to read this rather verbose plea for help.

Where to download replacement "Explorerframe.DLL" Files for x64 Windows 7 Pro?

- by Ben Franchuk

After posting this question, I did some research to reveal what the problem likely was, and found what I need to fix. Following this is the original post, then my updated question. A few months ago I ended up requiring to change my computer's SID to fix a problem it had been having- Instead of fixing the problem, though, it screwed up my at-the-time current install of windows, to the point of me needing to do a fresh install. As I am in possession of an OEM copy of Windows 7 Pro 64 Bit, I successfully reinstalled over the dead copy with that (all the files that were on the computer previous to this windows install were put in a Windows.old folder). Everything installed and worked absolutely fine, except for one thing. The problem I am experiencing is that, in some Windows Explorer windows, the explorer pane doesn't show. Instead, it simply shows a white area where the pane would show. This makes some software not usable, I recently realized; Software such as Cubase, which use just the explorer pane to select file save locations, cannot save at all as the pane itself is... not operational. Below is a screenshot of this problem as it occurs in cubase; ...and again as it shows in UTorrent in the save location selector window. The highlighted area is where the sidebar would NORMALLY be. Pardon my scribbling over some of the things in the window- I would personally rather the internet did not get a glimpse of my files. I have yet to find a common reason why the pane works in some applications when they pull explorer, and others not. I have yet to see it go away, and the software affected by it has been affected since I reinstalled my copy of windows. Initially, I was able to live with it as I can type out save locations in the file name bar to navigate, but with software like Cubase, I do not have this option. Reinstalling windows again is NOT an option. Here's the updated question. After posting this question originally, I did some research on the problem in question, and it turns out that this is extremely easily fixable via replacing the file "ExplorerFrame.DLL" which is located in the System32 and SystemWOW64 Folders, in the windows folder, on the C:\ drive. As I quite frequently customize my computer, this is a normal thing for me to do and I know exactly how to safely and properly replace this file. The only problem is that I cannot for the life of me find a download of this file that actually works with my computer. I tried a couple from some different sites but they all caused explorer to not restart (I was given an error when starting the application from Task Manager) and was forced to revert to the broken .DLL files. Since there are 2 separate "ExplorerFrame.DLL" files; one for 64 bit and the other for 32 bit, I am assuming that I will need to download 2 separate versions to replace the corrupted ones. Where can I acquire these files? I am currently running Windows 7 Professional x64 Bit.

FFMPEG dropping frames while encoding JPEG sequence at color change

- by Matt

I'm trying to put together a slide show using imagemagick and FFMPEG. I use imagemagick to expand a single photo into 30fps video (imagemagick also handles things like putting some text captions on the frames along the way). When I go to let ffmpeg digest it into a video it clips along nicely on the color parts of the video, but when it gets to a black and white section it reports "frame= 2030 fps=102 q=32766.0 Lsize= 5203kB time=00:01:07.60 bitrate= 630.5kbits/s dup=0 drop=703" and drops every frame of video until it hits something with color. As you can imagine this results in entire photos being removed from the slideshow. Here is my latest dump... ffmpeg -y -r 30 -i "teststream/%06d.jpg" -c:v libx264 -r 30 newffmpeg.mp4 ffmpeg version git-2012-12-10-c3bb333 Copyright (c) 2000-2012 the FFmpeg developers built on Dec 10 2012 22:02:04 with gcc 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3) configuration: --enable-gpl --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-librtmp --enable-libtheora --enable-libvorbis --enable-libx264 --enable-nonfree --enable-version3 libavutil 52. 12.100 / 52. 12.100 libavcodec 54. 79.101 / 54. 79.101 libavformat 54. 49.100 / 54. 49.100 libavdevice 54. 3.102 / 54. 3.102 libavfilter 3. 26.101 / 3. 26.101 libswscale 2. 1.103 / 2. 1.103 libswresample 0. 17.102 / 0. 17.102 libpostproc 52. 2.100 / 52. 2.100 Input #0, image2, from 'teststream/%06d.jpg': Duration: 00:12:02.80, start: 0.000000, bitrate: N/A Stream #0:0: Video: mjpeg, yuvj444p, 720x480 [SAR 72:72 DAR 3:2], 25 fps, 25 tbr, 25 tbn, 25 tbc [libx264 @ 0x3450140] using SAR=1/1 [libx264 @ 0x3450140] using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.2 [libx264 @ 0x3450140] profile High, level 3.0 [libx264 @ 0x3450140] 264 - core 129 r2 1cffe9f - H.264/MPEG-4 AVC codec - Copyleft 2003-2012 - http://www.videolan.org/x264.html - options: cabac=1 ref=3 deblock=1:0:0 analyse=0x3:0x113 me=hex subme=7 psy=1 psy_rd=1.00:0.00 mixed_ref=1 me_range=16 chroma_me=1 trellis=1 8x8dct=1 cqm=0 deadzone=21,11 fast_pskip=1 chroma_qp_offset=-2 threads=12 lookahead_threads=2 sliced_threads=0 nr=0 decimate=1 interlaced=0 bluray_compat=0 constrained_intra=0 bframes=3 b_pyramid=2 b_adapt=1 b_bias=0 direct=1 weightb=1 open_gop=0 weightp=2 keyint=250 keyint_min=25 scenecut=40 intra_refresh=0 rc_lookahead=40 rc=crf mbtree=1 crf=23.0 qcomp=0.60 qpmin=0 qpmax=69 qpstep=4 ip_ratio=1.40 aq=1:1.00 Output #0, mp4, to 'newffmpeg.mp4': Metadata: encoder : Lavf54.49.100 Stream #0:0: Video: h264 ([33][0][0][0] / 0x0021), yuvj420p, 720x480 [SAR 1:1 DAR 3:2], q=-1--1, 15360 tbn, 30 tbc Stream mapping: Stream #0:0 - #0:0 (mjpeg - libx264) Press [q] to stop, [?] for help Input stream #0:0 frame changed from size:720x480 fmt:yuvj444p to size:720x480 fmt:yuvj422p Input stream #0:0 frame changed from size:720x480 fmt:yuvj422p to size:720x480 fmt:yuvj444pp=584 frame= 2030 fps=102 q=32766.0 Lsize= 5203kB time=00:01:07.60 bitrate= 630.5kbits/s dup=0 drop=703 video:5179kB audio:0kB subtitle:0 global headers:0kB muxing overhead 0.472425% [libx264 @ 0x3450140] frame I:9 Avg QP:20.10 size: 33933 [libx264 @ 0x3450140] frame P:636 Avg QP:24.12 size: 6737 [libx264 @ 0x3450140] frame B:1385 Avg QP:27.04 size: 514 [libx264 @ 0x3450140] consecutive B-frames: 2.5% 15.2% 13.2% 69.2% [libx264 @ 0x3450140] mb I I16..4: 8.3% 80.3% 11.5% [libx264 @ 0x3450140] mb P I16..4: 1.5% 2.5% 0.2% P16..4: 41.7% 18.0% 10.3% 0.0% 0.0% skip:25.9% [libx264 @ 0x3450140] mb B I16..4: 0.0% 0.0% 0.0% B16..8: 26.6% 0.6% 0.1% direct: 0.2% skip:72.3% L0:35.0% L1:60.3% BI: 4.7% [libx264 @ 0x3450140] 8x8 transform intra:64.1% inter:75.1% [libx264 @ 0x3450140] coded y,uvDC,uvAC intra: 51.6% 78.0% 43.7% inter: 10.6% 14.9% 2.1% [libx264 @ 0x3450140] i16 v,h,dc,p: 29% 19% 6% 46% [libx264 @ 0x3450140] i8 v,h,dc,ddl,ddr,vr,hd,vl,hu: 23% 15% 17% 5% 9% 10% 7% 8% 6% [libx264 @ 0x3450140] i4 v,h,dc,ddl,ddr,vr,hd,vl,hu: 31% 18% 11% 5% 9% 10% 6% 6% 4% [libx264 @ 0x3450140] i8c dc,h,v,p: 46% 18% 24% 12% [libx264 @ 0x3450140] Weighted P-Frames: Y:20.1% UV:18.7% [libx264 @ 0x3450140] ref P L0: 59.2% 23.2% 13.1% 4.3% 0.2% [libx264 @ 0x3450140] ref B L0: 88.7% 8.3% 3.0% [libx264 @ 0x3450140] ref B L1: 95.0% 5.0% [libx264 @ 0x3450140] kb/s:626.88 Received signal 2: terminating. One last note: If I remove the -r 30 from the input and output it works flawlessly. I have no idea why the -r 30 is causing it to freak out.
