  • Telerik Releases the Data Service Wizard

    After a great beta cycle, Telerik is proud to announce today the commercial availability of the OpenAccess Data Service Wizard. You can download it and install it with Telerik OpenAccess Q1 2010 for both Visual Studio 2008 and 2010 RTM. If you are new to the Data Service Wizard, it is a great tool that will allow you to point a wizard at your OpenAccess generated data access classes and automatically build an WCF, Astoria (WCF Data Services), REST or ATOMPub collection endpoint, complete with the CRUD methods if applicable. If you are familiar with the Data Service Wizard already, there will be two new surprises in the release version. If you generated a domain model with the new OpenAccess Visual Entity Designer, you have only one file added to your project, mydomainmodel.rlinq for example. The first surprise of the new Data Service Wizard is that if you right click on the domain model in Visual Studio, ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Multithreaded UI desktop application issues

    - by igor
    I am involved into development a rich UI project: desktop windows application. Application uses asynchronous invocations and in its turn it should be ready to process external messages (events). The problem is clear: at first time it was built as a simple prototype and it was not stress tested and all was fine. Then application was grown: the number of calls to server and number of events from server are high and performance is low. What is more users noticed that sometimes performance is extremal low. Asynchronous invocations based on thread pool (BeginInvoke, EndInvoke), external events are going from WCF service (.NET 3.5). My goal is synchronization of all tasks and putting priorities to every executions in desktop application. My question is: is there any practice how to reach my goal: patterns, task priority list, others? What should I do at first, second and next times? Thanks

  • Moving Forward with Code Iteration

    - by rcapote
    There are times when working on my programming projects, and I get to a point where I'm ready to move on to the next part of my program. However, when I sit down to implement this new feature I get stuck, in a sense. It's not that I don't know how to implement the feature, it's that I get stuck on figuring out the best way to implement said feature. So I sit back for a day or two and let the ideas ferment until I am comfortable with a design. I get worried that I may not write something as well as it could be, or that I might have to go back and rework the whole thing; so I put it off. This is a big reason why I've never really finished many personal projects. Anyone else experience this, and how do you keep your self moving forward in your project?

  • XNA Deferred Shading, Replace BasicEffect

    - by Alex
    I have implemented deferred shading in my XNA 4.0 project, meaning that I need all objects to start out with the same shader "RenderGBuffer.fx". How can I use a custom Content Processor to: Not load any textures by default (I want to manually do this) Use "RenderGBuffer.fx" as the default shader instead of BasicEffect Below is the progress so far public class DeferredModelProcessor : ModelProcessor { EffectMaterialContent deferredShader; public DeferredModelProcessor() { } protected override MaterialContent ConvertMaterial(MaterialContent material, ContentProcessorContext context) { deferredShader = new EffectMaterialContent(); deferredShader.Effect = new ExternalReference<EffectContent>("DeferredShading/RenderGBuffer.fx"); return context.Convert<MaterialContent, MaterialContent>(deferredShader, typeof(MaterialProcessor).Name); } }

  • Display root node of Hierarchical Tree using ADF - EJB DC

    - by arul.wilson(at)oracle.com
    Displaying Employee (HR schema) records in Hierarchical Tree can be achieved in ADF-BC by creating custom VO and a Viewlink for displaying root node. This can be more easily done using  EJB-DC by just introducing a NamedQuery to get the root node.Here you go to get this scenario working.Create DB connection based on HR schema.Create Entity Bean from Employees Table.Add custom NamedQuery to Employees.java bean, this named query is responsible for fetching the root node (King in this example). @NamedQueries({  @NamedQuery(name = "Employees.findAll", query = "select o from Employees o"),  @NamedQuery(name = "Employees.findRootEmp", query = "select p from Employees p where p.employees is null")}) Create Stateless Session Bean and expose the Named Queries through the Session Facade.Create Datacontrol from SessionBean local interface.Create jspx page in ViewController project.Drop employeesFindRootEmp from Data Controls Palette as ADF Tree.Add employeesList as Tree level rule.Run page to see the hierarchical tree with root node as 'King'

  • "initialization error: class file has wrong version" message in JDeveloper 10.1.2.x

    - by [email protected]
    The "initialization error: class file has wrong version" has become a somewhat recurrent error message thrown by JDeveloper 10.1.2.x as newer JDKs have been released in the last years. Note that JDeveloper 10.1.2 was developed to run with JDK 1.4.2. The reasons for this error message to be thrown include: A JDK version higher than 1.4.2 is being used and some unexpected incompatibility conflicts can occur because of that Some of the libraries used on the workspace and/or project were compiled with newer JDK version So, it is strongly recommended to use newer JDeveloper versions (10.1.3 - 11g) for newer JDKs. JDeveloper 10.1.2 will be desupported in December 2010 (or later depending on the support contract). Further information about this can be seen at http://www.oracle.com/support/library/brochure/lifetime-support-middleware.pdf

  • Who is Configuration Manager?

    - by altern
    I would like to ask members of the community about the role of Configuration Manager, as you see it. I'm not asking what Configuration Management is, as long it had been asked before. What I need to know is: What tasks do you think Configuration Manager should perform (or performs) in your team? What is primary responsibility of Configuration Manager? What are secondary/auxiliary responsibilities of Configuration Manager? Does Configuration Manager need to be in charge of development processes on the project/company or he should be told what to do? What are relations between Configuration Manager, Build Manager, Release Manager, Deployment Engineer, CI Engineer roles? Aren't they all the same - Configuration Management? Maybe term Configuration Management is redundant and Technical/Team Lead should do all the related work instead? It would be really great if you could share your vision and experience.

  • REST or Non-REST on Internal Services

    - by tyndall
    I'm curious if others have chosen to implement some services internally at their companies as non-REST (SOAP, Thrift, Proto Buffers, etc...) as a way to auto-generate client libraries/wrappers? I'm on a two year project. I will be writing maybe 40 services over that period with my team. 10% of those services definitely make sense as REST services, but the other 90% feel more like they could be done in REST or RPC style. Of these 90%, 100% will be .NET talking to .NET. When I think about all the effort to have my devs develop client "wrappers" for REST services I cringe. WADL or RSDL don't seem to have enough mindshare. Thoughts? Any good discussions of this "internal service" issue online? If you have struggled with this what general rules for determining REST or non-REST have you used?

  • Security issue about making my code public in GitHub

    - by John Doe
    I'm developing a big community/forum website and I'd like to upload my code to GitHub to have at least some sort of version control over it (because I have nothing other than a .rar file as a backup, not even SVN), to let others contribute to the project, and also perhaps using it to let my potential future employers see some of my code as some sort of curriculum. But what I'm wondering now, and I'm suprised I haven't seen anyone mention it before is the security aspect of it. Isn't publishing the code of a website a HUGE security hole? Is like giving a potential hacker or anyone who would like to find any potential exploit possible, even considering that the critical files aren't uploaded (database passwords, authentication scripts, etc.). Of course that there are millions of projects uploaded to GitHub and no one will find mine just 'by chance'. But if they look for it, it would indeed be there. Bottomline: my problem is not about copyright or licenses, but others finding exploits in my website. I'm I missing something here?

  • In the Mobile and Tablet World, How Much is Too Much?

    - by andrewbrust
    The week of April 26th was a huge one in the world of mobile and tablet devices,  There were so many individual developments, announcements and solidifications of strategy, it’s almost impossible to believe they occurred in the same month, let alone the same week. Things started with Apple and Gizmodo having a Law and Order moment over the latter’s procurement of what appears to be the former’s 4th gen iPhone prototype.  We found out on the 26th that Gizmodo blogger Jason Chen’s apartment was raided by police and, honestly, that was a bit much. But Apple didn’t stop there.  They also published Steve Job’s critique of Adobe Flash and his explanation of Cupertino’s embargo of Flash on iPhones, iPods and iPads.  If you ask me, this too, was a bit much. Apple finished up the week by releasing the 3G version of its iPad product to the US market. I like (iLike?) my WiFi iPad.  The idea of getting a version of it that required a second 3G service monthly subscription, is, well, a bit  much. Microsoft was in the news too.  It killed a project it hadn’t even acknowledged the existence of: the Courier tablet.  That’s a bit much too.  If a tree falls in the woods, and Microsoft says they can’t hear it anyway, could they really have chopped it down? Maybe Microsoft Research should have licensed some of Courier’s technology from other parts of Microsoft.  Then maybe they could have kept the product alive.  Ask HTC: they’re going to be licensing technology from Microsoft because Redmond insists that Google’s Android operating system infringes on certain of their patents.  And since HTC now builds a number of handsets on Android, instead of being beholden, as they once were, to Windows Mobile, that means they can keep making their products.  Why does HTC have to pay the royalties, and not Google?  Maybe Microsoft decided that going after GOOG would have been a bit much, even for them. The agreement came not a moment to soon: HTC released their “Droid Incredible” (that name’s a bit much), an Android 2.1 handset with amazing hardware and HTC’s own Sense UI, on April 30th (this past Friday). This phone is very well-reviewed.  Maybe that’s why Google basically decided to beg off introducing a version of its Nexus One phone (also manufactured by HTC) on the Verizon Wireless network.  Google backing down?  That’s incredible, if not also a bit much. And that brings us to HP.  Which this week announced its acquisition of Palm and its webOS mobile phone touch-oriented operating system.  HP also killed its own Slate initiative.  Apparently HP realized that Windows 7, even with a proprietary HP touch UI added on top, is no match for the iPad.  I’m guessing they think webOS might work a bit better,  And I’m wondering if HP even wants to use webOS for phone handsets, beyond the Pre and Pixi.  Using it just for slate devices would be a bit extreme, but maybe not too much. Honestly, this was not Microsoft’s best week.  It killed a project and a close partner did likewise.  Then that same partner bought a competing OS product, while another partner released their new product that uses yet another competing OS platform. What did Microsoft actually produce this past week? An update to its Windows Phone 7 developer tools that actually works with the version of Visual Studio 2010 released on April 12th, and the version of Silverlight released three days later. That took three weeks to get synced up, and that’s a bit much too. But at least it happened. Windows Phone 7 is Microsoft’s best hope for a comeback in the SmartPhone market and to offer a credible touch-based tablet device.  This week, two of Microsoft’s slate initiatives died, and its only mobile phone victory was around its competitor’s operating system.  I hope the new platform gets Redmond out of the PC ghetto and into the classes of device that get people really excited today.  If it can’t, that would be a bit much; probably too much.  And, as the signs at the Lonestar Cafe in NYC used to say, too much ain’t enough.

  • MD5 vertex skinning problem extending to multi-jointed skeleton (GPU Skinning)

    - by Soapy
    Currently I'm trying to implement GPU skinning in my project. So far I have achieved single joint translation and rotation, and multi-jointed translation. The problem arises when I try to rotate a multi-jointed skeleton. The image above shows the current progress. The left image shows how the model should deform. The middle image shows how it deforms in my project. The right shows a better deform (still not right) inverting a certain value, which I will explain below. The way I get my animation data is by exporting it to the MD5 format (MD5mesh for mesh data and MD5anim for animation data). When I come to parse the animation data, for each frame, I check if the bone has a parent, if not, the data is passed in as is from the MD5anim file. If it does have a parent, I transform the bones position by the parents orientation, and the add this with the parents translation. Then the parent and child orientations get concatenated. This is covered at this website. if (Parent < 0){ ... // Save this data without editing it } else { Math3::vec3 rpos; Math3::quat pq = Parent.Quaternion; Math3::quat pqi(pq); pqi.InvertUnitQuat(); pqi.Normalise(); Math3::quat::RotateVector3(rpos, pq, jv); Math3::vec3 npos(rpos + Parent.Pos); this->Translation = npos; Math3::quat nq = pq * jq; nq.Normalise(); this->Quaternion = nq; } And to achieve the image to the right, all I need to do is to change Math3::quat::RotateVector3(rpos, pq, jv); to Math3::quat::RotateVector3(rpos, pqi, jv);, why is that? And this is my skinning shader. SkinningShader.vert #version 330 core smooth out vec2 vVaryingTexCoords; smooth out vec3 vVaryingNormals; smooth out vec4 vWeightColor; uniform mat4 MV; uniform mat4 MVP; uniform mat4 Pallete[55]; uniform mat4 invBindPose[55]; layout(location = 0) in vec3 vPos; layout(location = 1) in vec2 vTexCoords; layout(location = 2) in vec3 vNormals; layout(location = 3) in int vSkeleton[4]; layout(location = 4) in vec3 vWeight; void main() { vec4 wpos = vec4(vPos, 1.0); vec4 norm = vec4(vNormals, 0.0); vec4 weight = vec4(vWeight, (1.0f-(vWeight[0] + vWeight[1] + vWeight[2]))); normalize(weight); mat4 BoneTransform; for(int i = 0; i < 4; i++) { if(vSkeleton[i] != -1) { if(i == 0) { // These are interchangable for some reason // BoneTransform = ((invBindPose[vSkeleton[i]] * Pallete[vSkeleton[i]]) * weight[i]); BoneTransform = ((Pallete[vSkeleton[i]] * invBindPose[vSkeleton[i]]) * weight[i]); } else { // These are interchangable for some reason // BoneTransform += ((invBindPose[vSkeleton[i]] * Pallete[vSkeleton[i]]) * weight[i]); BoneTransform += ((Pallete[vSkeleton[i]] * invBindPose[vSkeleton[i]]) * weight[i]); } } } wpos = BoneTransform * wpos; vWeightColor = weight; vVaryingTexCoords = vTexCoords; vVaryingNormals = normalize(vec3(vec4(vNormals, 0.0) * MV)); gl_Position = wpos * MVP; } The Pallete matrices are the matrices calculated using the above code (a rotation and translation matrix get created from the translation and quaternion). The invBindPose matrices are simply the inverted matrices created from the joints in the MD5mesh file. Update 1 I looked at GLM to compare the values I get with my own implementation. They turn out to be exactly the same. So now i'm checking if there's a problem with matrix creation... Update 2 Looked at GLM again to compare matrix creation using quaternions. Turns out that's not the problem either.

  • Exposing business logic as WCF service

    - by Oren Schwartz
    I'm working on a middle-tier project which encapsulates the business logic (uses a DAL layer, and serves a web application server [ASP.net]) of a product deployed in a LAN. The BL serves as a bunch of services and data objects that are invoked upon user action. At present times, the DAL acts as a separate application whereas the BL uses it, but is consumed by the web application as a DLL. Both the DAL and the web application are deployed on different servers inside organization, and since the BL DLL is consumed by the web application, it resides in the same server. The worst thing about exposing the BL as a DLL is that we lost track with what we expose. Deployment is not such a big issue since mostly, product versions are deployed together. Would you recommend migrating from DLL to WCF service? If so, why? Do you know anyone who had a similar experience?

  • Avoid GPL violation by moving library out of process

    - by Andrey
    Assume there is a library that is licensed under GPL. I want to use it is closed source project. I do following: Create small wrapper application around that GPL library that listens to socket, parse messages and call GPL library. Then returns results back. Release it's sources (to comply with GPL) Create client for this wrapper in my main application and don't release sources. I know that this adds huge overhead compared to static/dynamic linking, but I am interested in theoretical way.

  • Learning a new language using broken unit tests

    - by Brian MacKay
    I was listening to a dot net rocks the other day where they mentioned, almost in passing, a really intriguing tool for learning new languages -- I think they were specifically talking about F#. It's a solution you open up and there are a bunch of broken unit tests. Fixing them walks you through the steps of learning the language. I want to check it out, but I was driving in my car and I have no idea what the name of the project is or which dot net rocks episode it was. Google hasn't helped much. Any idea?

  • SOA Suite 11g Dynamic Payload Testing with soapUI Free Edition

    - by Greg Mally
    Overview Many web service developers use soapUI for various tests like: smoke test, unit test, and load testing because you can get a free edition that is fairly robust. However, if you need to venture into more complex testing that requires a dynamic payload, then the free edition doesn't necessarily make it easy. This feature does exist in soapUI, but for obvious reasons it is in the Pro version. In this blog I will show you how to use soapUI free edition for dynamic payloads in a simplified example. Hopefully this will open the doors for you to expand into more complex scenarios. The following assumes that you have a working knowledge of soapUI and will not go into concepts like setting up a project etc. For the basics, please review the documentation for soapUI: http://www.soapui.org/Getting-Started/. Additionally, we will be using asynchronous web services and you can review the setup for this in my blog: SOA Suite 11g Asynchronous Testing with soapUI. Features in soapUI Free Edition Relating to this Topic The soapUI test tool provides a very feature rich environment that can do many things provided you are willing to go beyond point and click. For this example, we will be leveraging just a couple features for our dynamic payload example: Test Case Properties Scripting with Groovy Basically, we will be using a property as a global variable and we will manipulate that property using a Groovy script. Setting Up Our Property Properties are available throughout soapUI and here is a snippet from the soapUI website defining the locations: Projects : for handling Project scope values, for example a subscription ID TestSuite : for handling TestSuite scoped values, can be seen as "arguments" to a TestSuite TestCases : for handling TestCase scoped values, can be seen as "arguments" to a TestCase Properties TestStep : for providing local values/state within a TestCase Local TestStep properties : several TestStep types maintain their own list of properties specific to their functionality : DataSource, DataSink, Run TestCase MockServices : for handling MockService scoped values/arguments MockResponses : for handling MockResponse scoped values Global Properties : for handling Global properties, optionally from an external source For our example, we will be defining a custom property in a TestCase called SimpleAsyncPayload. The property can be created in either the Custom Properties tab located at the bottom of the Navigator panel when the TestCase is selected in the Navigator or the Properties label in the TestCase editor: Navigator Panel TestCase Editor You will notice that I set a value of “0” for the custom property. For this simplified example, we will need to retrieve that value and manipulate it prior to making the web service request invocation. In order to accomplish this, we will need to get Groovy ;) Let's Get Groovy We will now add a new Groovy Script step to the TestCase called Manipulate Payload: TestCase Editor > Append Step > Groovy Script Once we have added the Groovy Script step to our TestCase, we can open the Groovy Script editor to add the code to: Get the current value of the property we created called SimpleAsyncPayload. Convert the value of the property to an integer. Increment the value. Store the incremented value back into the TestCase property called SimpleAsyncPayload. The script should look something like the following: Groovy Script Editor – Manipulate Payload At this point we can test the script to see if it is working by simply running the TestCase (left-click on the green triangle in the upper left-hand corner of the TestCase editor). To verify if it ran correctly, we can look at the value of the SimpleAsyncPayload property which should now be 1: TestCase Editor – Run Results All that is left to complete the TestCase is to append another step of type Test Request. The information required to append the request is a name and an operation to invoke. In this example we will use the default name and select the SimpleAsyncBPELProcessBingd -> process as the operation (any other information being requested, simply use the defaults unless you are calling an asynchronous operation then do not add any assertions). We are now in familiar ground with the Test Request editor. Depending upon the type of operation you are invoking (synchronous or asynchronous), please update the request with the necessary information (e.g., callback information for asynchronous operations). We will now tweak the Test Request payload to retrieve the value of the SimpleAsyncPayload property. The soapUI editor makes this very simple: right-click in the payload and navigate to the property (e.g., right-click > Get Data.. > TestCase: [Groovy TestCase] > Property [SimpleAsyncPayload]): Test Request Editor – Insert Property Value Your payload should now look something like the following: Test Request Editor – Inserted Property Value Just like before, we are now ready to run the TestCase. If everything goes as expected we should see a response like the following: Message Viewer – Results of TestCase Run We are now setup to be able to run a stress test where the payload will change for each request. This simple example can be expanded to include multiple payload values, complex calculations in the scripts, or whatever can be done via the soapUI scripting. Hopefully you have found this useful and happy testing to you :)

  • Motion Sensing Fog Machine Increases Savings and Spook Factor

    - by Jason Fitzpatrick
    This DIY add-on switches a standard fog machine from always-on to motion-activated–increase your savings and spook factor at the same time. Courtesy of tinker Greg, this modification involves a new relay and motion sensor mounted onto the existing switch of a store-bought fog machine. When the motion-sensor detects motion the fog machine releases a burst of fog for 5 seconds and then disarms itself for 10 seconds–long enough for the startled victim to move on and for the machine to recharge for the next passerby. Check out the video above to see it in action and then hit up the link below to see the project’s build guide.

  • New JDeveloper/ADF book hits the bookshelves

    - by Grant Ronald
    I've just received a nice new copy of Sten Vesterli's book Oracle ADF Enterprise Application Development - Made Simple.  I was one of the technical reviewers of the book but I'm looking forward to be able to read it end-to-end in good old fashioned book format this coming week. The book bridges the gap between those existing books that describe Oracle ADF features, and real world ADF development.  So, source control, bug tracking, estimating, testing, security, packaging etc are all covered.  Of course, every project and situation is different so the book could never supply a one-size-fits-all guide, but I think its a good addition to your ADF bookshelf.  I'll hopefully post a full review in the coming weeks. Oh, and congratulations Sten,  having gone through the pain of writing my own ADF book, I take my hat off to anyone who goes through the same journey!

  • Methods to Manage/Document "one-off" Reports

    - by Jason Holland
    I'm a programmer that also does database stuff and I get a lot of so-called one-time report requests and recurring report requests. I work at a company that has a SQL Server database that we integrate third-party data with and we also have some third-party vendors that we have to use their proprietary reporting system to extract data in flat file format from that we don't integrate into SQL Server for security reasons. To generate many of these reports I have to query data from various systems, write small scripts to combine data from the separate systems, cry, pull my hair, curse the last guy's name that made the report before me, etc. My question is, what are some good methods for documenting the steps taken to generate these reports so the next poor soul that has to do them won't curse my name? As of now I just have a folder with subfolders per project with the selects and scripts that generated the last report but that seems like a "poor man's" solution. :)

  • Software rendering 3d triangles in the proper order

    - by at.
    I'm implementing a basic 3d rendering engine in software (for education purposes, please don't mention to use an API). When I project a triangle from 3d to 2d coordinates, I draw the triangle. However, it's in a random order and so whatever gets drawn last draws on top of all other triangles (which might be in front of triangles it shouldn't be in front of)... Intuitively, seems I need to draw the triangles in the correct order. So I can calculate all their distances to the camera and sort by that. The objects furthest away get drawn last. Is this the proper way to render triangles? If I'm sorting all the objects, this is n*log(n) now. Is this the most efficient way to do this?

  • Where to find clients?

    - by Zenph
    My main area: web development. Of course, I don't expect anybody give away their 'gold mine' or whatever but I am struggling to see where I should be advertising my services. I have one other developer I work with and we have a lot of happy clients - on freelance websites. Thing is, freelance websites just seem to suck the life out of you when you're being out-bidded by ridiculous rates. I want to attract customers who are more concerned about quality and accountability than price. Any suggestions at all? I'm so lost with this. EDIT: Added bounty of 200 - all of my 'reputation'. EDIT: Added second bounty of 50 I did hear of a novel idea. Do work for an opensource project and get featured in their 'trusted developers' section, if they have one. Input?

  • Why is Adobe Air so underrated for building mobile apps?

    - by Marcelo de Assis
    I worked with Adobe Flash related technologies for the last 5 years, although not being a big fan of Adobe. I see some little bugs happening in some apps, but I cannot imagine why a lot of big companies do not even think to use use Adobe Air as a good technology for their mobile apps. I see a lot of mobile developer positions asking for experts in Android or iOS , but very much less positions asking for Adobe Air, even when Adobe Air apps have the advantage of being multi-plataform, with the same app working in Blackberry, iOS and Android. Is so much easier to develop a game using Flash, than using Android SDK, for example. It really have flaws (that I never saw) or it is just some kind of mass prejudgement?
