Using the SOA-BPM VIrtualBox Appliance

- by antony.reynolds

Quickstart Guide to Using Oracle Appliance for SOA/BPM Recently I have been setting up some machines for fellow engineers. My base setup consists of Oracle Enterprise Linux with Oracle Virtual Box. Note that after installing VirtualBox I needed to add the VirtualBox Extension Pack to enable RDP access amongst other features. In order to get them started quickly with some images I downloaded the pre-built appliance for SOA/BPM from OTN. Out of the box this provides a VirtualBox image that is pre-installed with everything you will need to develop SOA/BPM applications. Specifically by using the virtual appliance I got the following pre-installed and configured. Oracle Enterprise Linux 5 User oracle password oracle User root password oracle. Oracle Database XE Pre-configured with SOA/BPM repository. Set to auto-start on OS startup. Oracle SOA Suite 11g PS2 Configured with a “collapsed domain”, all services (SOA/BAM/EM) running in AdminServer. Listening on port 7001 Oracle BPM Suite 11g Configured in same domain as SOA Suite. Oracle JDeveloper 11g With SOA/BPM extensions. Networking The VM by default uses NAT (Network Address Translation) for network access. Make sure that the advanced settings for port forwarding allow access through the host to guest ports. It should be pre-configured to forward requests on the following ports Purpose Host Port Guest Port (VBox Image) SSH 2222 22 HTTP 7001 7001 Database 1521 1521 Note that only one VirtualBox image can use a given host port, so make sure you are not clashing if it seems not to work. What’s Left to Do? There is still some customization of the environment that may be required. If you need to configure a proxy server as I did then for the oracle and root users to set up an HTTP proxy Added “export http_proxy=http://proxy-host:proxy-port” to ~oracle/.bash_profile and ~root/.bash_profile Added “export http_proxy=http://proxy-host:proxy-port” to /etc/.bashrc Edited System->Preferences to set Network Proxy In Firefox set Preferences->Network->Connection Settings to “Use system proxy settings” In JDeveloper set Edit->Preferences->Web Browser and Proxy to required proxy settings You may need to configure yum to point to a public OEL yum repository – such as http://public-yum.oracle.com. If you are going to be accessing the SOA server from outside the VirtualBox image then you may want to set the soa-infra Server URLs to be the hostname of the host OS. Snap! Once I had the machine configured how I wanted to use it I took a snapshot so that I can always get back to the pristine install I have now. Snapshots are one of the big benefits of putting a development environment into a virtualized environment. I can make changes to my installation and if I mess it up I can restore the image to a last known good snapshot. Hey Presto!, Ready to Go This is the quickest way to get up and running with SOA/BPM Suite. Out of the box the download will work, I only did extra customization so I could use services outside the firewall and browse outside the firewall from within by SOA VirtualBox image. I also use yum to update the OS to the latest binaries. So have fun.

Monitor and Control Memory Usage in Google Chrome

- by Asian Angel

Do you want to know just how much memory Google Chrome and any installed extensions are using at a given moment? With just a few clicks you can see just what is going on under the hood of your browser. How Much Memory are the Extensions Using? Here is our test browser with a new tab and the Extensions Page open, five enabled extensions, and one disabled at the moment. You can access Chrome’s Task Manager using the Page Menu, going to Developer, and selecting Task manager… Or by right clicking on the Tab Bar and selecting Task manager. There is also a keyboard shortcut (Shift + Esc) available for the “keyboard ninjas”. Sitting idle as shown above here are the stats for our test browser. All of the extensions are sitting there eating memory even though some of them are not available/active for use on our new tab and Extensions Page. Not so good… If the default layout is not to your liking then you can easily modify the information that is available by right clicking and adding/removing extra columns as desired. For our example we added Shared Memory & Private Memory. Using the about:memory Page to View Memory Usage Want even more detail? Type about:memory into the Address Bar and press Enter. Note: You can also access this page by clicking on the Stats for nerds Link in the lower left corner of the Task Manager Window. Focusing on the four distinct areas you can see the exact version of Chrome that is currently installed on your system… View the Memory & Virtual Memory statistics for Chrome… Note: If you have other browsers running at the same time you can view statistics for them here too. See a list of the Processes currently running… And the Memory & Virtual Memory statistics for those processes. The Difference with the Extensions Disabled Just for fun we decided to disable all of the extension in our test browser… The Task Manager Window is looking rather empty now but the memory consumption has definitely seen an improvement. Comparing Memory Usage for Two Extensions with Similar Functions For our next step we decided to compare the memory usage for two extensions with similar functionality. This can be helpful if you are wanting to keep memory consumption trimmed down as much as possible when deciding between similar extensions. First up was Speed Dial”(see our review here). The stats for Speed Dial…quite a change from what was shown above (~3,000 – 6,000 K). Next up was Incredible StartPage (see our review here). Surprisingly both were nearly identical in the amount of memory being used. Purging Memory Perhaps you like the idea of being able to “purge” some of that excess memory consumption. With a simple command switch modification to Chrome’s shortcut(s) you can add a Purge Memory Button to the Task Manager Window as shown below. Notice the amount of memory being consumed at the moment… Note: The tutorial for adding the command switch can be found here. One quick click and there is a noticeable drop in memory consumption. Conclusion We hope that our examples here will prove useful to you in managing the memory consumption in your own Google Chrome installation. If you have a computer with limited resources every little bit definitely helps out.

Acr.ExtDirect – Part 1 – Method Resolvers

- by Allan Ritchie

One of the most important things of any open source libraries in my opinion is to be as open as possible while avoiding having your library become invasive to your code/business model design. I personally could never stand marking my business and/or data access code with attributes everywhere. XML also isn’t really a fav with too many people these days since it comes with a startup performance hit and requires runtime compiling. I find that there is a whole ton of communication libraries out there currently requiring this (ie. WCF, RIA, etc). Even though Acr.ExtDirect comes with its own set of attributes, you can piggy-back the [ServiceContract] & [OperationContract] attributes from WCF if you choose. It goes beyond that though, there are 2 others “out-of-the-box” implementations – Convention based & XML Configuration. Convention – I don’t actually recommend using this one since it opens up all of your public instance methods to remote execution calls. XML Configuration – This isn’t so bad but requires you enter all of your methods and there operation types into the Castle XML configuration & as I said earlier, XML isn’t the fav these days. So what are your options if you don’t like attributes, convention, or XML Configuration? Well, Acr.ExtDirect has its own extension base to give the API a list of methods and components to make available for remote execution. 1: public interface IDirectMethodResolver { 2: 3: bool IsServiceType(ComponentModel model, Type type); 4: string GetNamespace(ComponentModel model); 5: string[] GetDirectMethodNames(ComponentModel model); 6: DirectMethodType GetMethodType(ComponentModel model, MethodInfo method); 7: } Now to implement our own method resolver: 1: public class TestResolver : IDirectMethodResolver { 2: 3: #region IDirectMethodResolver Members 4: 5: /// <summary> 6: /// Determine if you are calling a service 7: /// </summary> 8: /// <param name="model"></param> 9: /// <param name="type"></param> 10: /// <returns></returns> 11: public bool IsServiceType(ComponentModel model, Type type) { 12: return (type.Namespace == "MyBLL.Data"); 13: } 14: 15: /// <summary> 16: /// Return the calling name for the client side 17: /// </summary> 18: /// <param name="model"></param> 19: /// <returns></returns> 20: public string GetNamespace(ComponentModel model) { 21: return model.Name; 22: } 23: 24: public string[] GetDirectMethodNames(ComponentModel model) { 25: switch (model.Name) { 26: case "Products" : 27: return new [] { 28: "GetProducts", 29: "LoadProduct", 30: "Save", 31: "Update" 32: }; 33: 34: case "Categories" : 35: return new [] { 36: "GetProducts" 37: }; 38: 39: default : 40: throw new ArgumentException("Invalid type"); 41: } 42: } 43: 44: public DirectMethodType GetMethodType(ComponentModel model, MethodInfo method) { 45: if (method.Name.StartsWith("Save") || method.Name.StartsWith("Update")) 46: return DirectMethodType.FormSubmit; 47: 48: else if (method.Name.StartsWith("Load")) 49: return DirectMethodType.FormLoad; 50: 51: else 52: return DirectMethodType.Direct; 53: } 54: 55: #endregion 56: } And there you have it, your own custom method resolver. Pretty easy and pretty open ended!

SAB BizTalk Archiving Pipeline Component - Codeplex

- by Stuart Brierley

In an effort to give a little more to the BizTalk development community, I have created my first Codeplex project. The SAB BizTalk Archiving Pipeline Component was written using Visual Studio 2010 with BizTalk Server 2010 intended as the target platform. It is currently at version 0.1, meaning that I have not yet completed all the intended functionality and have so far carried out a limited number of tests. It does however archive files within the bounds of the functionailty so far implemented and seems to be stable in use. It is based on a recent evolution of a basic archiving component that I wrote in the past, and it is my hope that it will continue to evolve in the coming months. This work was inspired by some old posts by Gilles Zunino and Jeff Lynch. You can download the documentation, source code or component dll from Codeplex, but to give you a taste here is the first section of the documentation to whet your appetite: SAB BizTalk Archiving Pipeline Component The SAB BizTalk Archiving Pipeline Component has been developed to allow custom piplelines to be created that can archive messages at any stage of pipeline processing. It works in both receive and send pipelines and will archive messages to file based on the configuration applied to the component in the BizTalk Administration Console. The Archiving Pipeline Component has been coded for use with BizTalk Server 2010. Use with other versions of BizTalk has not been tested. The Archiving Pipeline component is supplied as a dll file that should be placed in the BizTalk Server Pipeline Components folder. It can then be used when developing custom pipelines to be deployed as a part of your BizTalk Server applications. This version of the component allows you to use a number of generic messaging macros and also a small number that are specific to the FILE adapter. It is intended to extend these macros to cover context properties from other adapters in future releases. Archive Pipeline Parameters As with all pipeline components, the following parameters can be set when creating your custom pipeline and at runtime via the administration console. Enabled: Enables and disables the archive process. True; messages will be archived. False; messages will be passed to the next stage in the pipeline without performing any processing. File Name: The file name of the archived message. Allows the component to build the archive filename at run-time; based on the values entered, the permitted macros and data extracted from the message context properties. e.g. %FileReceivedFileName%-%InterchangeSequenceNumber% File Mask: The extension to be added to the File Name following all Macro processing. e.g. .xml File Path: The path on which the archived message should be saved. Allows the component to build the archive directory at run-time; based on the values entered, permitted macros and data extracted from the message context properties. e.g. C:\Archive\%ReceivePortName%\%Year%\%Month%\%Day%\ \\ArchiveShare\%ReceivePortName%\%Date%\ Overwrite: Enables and disables existing file overwrites. True; any existing file with the same File Path/Name combination (following macro replacement) will be overwritten. False; any existing file with the same File Path/Name combination (following macro replacement) will not be overwritten. The current message will be archived with a GUID appended to the File Name.

Templated Razor Delegates – Phil Haack

- by nmarun

This post is largely based off of Phil Haack’s article titled Templated Razor Delegates. I strongly recommend reading this article first. Here’s a sample code for the same, so you can have a look at. I also have a custom type being rendered as a table. 1: // my custom type 2: public class Device 3: { 4: public int Id { get; set; } 5: public string Name { get; set; } 6: public DateTime MfgDate { get; set; } 7: } Now I can write an extension method just for this type. 1: public static class RazorExtensions 2: { 3: public static HelperResult List(this IList<Models.Device> devices, Func<Models.Device, HelperResult> template) 4: { 5: return new HelperResult(writer => 6: { 7: foreach (var device in devices) 8: { 9: template(device).WriteTo(writer); 10: } 11: }); 12: } 13: // ... 14: } Modified my view to make it a strongly typed one and included html to render my custom type collection in a table. 1: @using TemplatedRazorDelegates 2: @model System.Collections.Generic.IList<TemplatedRazorDelegates.Models.Device> 3: 4: @{ 5: ViewBag.Title = "Home Page"; 6: } 7: 8: <h2>@ViewBag.Message</h2> 9: 10: @{ 11: var items = new[] { "one", "two", "three" }; 12: IList<int> ints = new List<int> { 1, 2, 3 }; 13: } 14: 15: <ul> 16: @items.List(@<li>@item</li>) 17: </ul> 18: <ul> 19: @ints.List(@<li>@item</li>) 20: </ul> 21: 22: <table> 23: <tr><th>Id</th><th>Name</th><th>Mfg Date</th></tr> 24: @Model.List(@<tr><td>@item.Id</td><td>@item.Name</td><td>@item.MfgDate.ToShortDateString()</td></tr>) 25: </table> We get intellisense as well! Just added some items in the action method of the controller: 1: public ActionResult Index() 2: { 3: ViewBag.Message = "Welcome to ASP.NET MVC!"; 4: IList<Device> devices = new List<Device> 5: { 6: new Device {Id = 1, Name = "abc", MfgDate = new DateTime(2001, 10, 19)}, 7: new Device {Id = 2, Name = "def", MfgDate = new DateTime(2011, 1, 1)}, 8: new Device {Id = 3, Name = "ghi", MfgDate = new DateTime(2003, 3, 15)}, 9: new Device {Id = 4, Name = "jkl", MfgDate = new DateTime(2007, 6, 6)} 10: }; 11: return View(devices); 12: } Running this I get the output as: Absolutely brilliant! Thanks to both Phil Haack and to David Fowler for bringing this out to us. Download the code for this from here. Verdict: RazorViewEngine.Points += 1;

regarding the Windows Phone 7 series, XNA and Visual Basic

- by Chris Williams

as long as we're talking about VB... I figured I would share this as well. Hi everyone, I'm about to express a sentiment that might ruffle a few feathers, but I think most of you know me well enough to know I love like accept VB for what it is and that what I'm about to say is with good intentions. (The rest of you, who don't know me, please take my word for it.) The world is full of VB developers, I was one of them for a long time. I think it's safe to assume that none of us are ignorant people who require handholding. We're working professionals, making a living by using our skills as developers. I'm also willing to bet that quite a few of us are fluent in C# as well as VB. It may not be your preferred language, but many of you can do it and you prove that nearly every day. Honestly, I don't know ANY developers or consultants that have only known ONE language ever. So it pains me greatly when I see the word "CAN'T" being tossed around like a crutch... as in "we CAN'T develop for the windows phone or we CAN'T develop XNA games." At MIX, Microsoft hath decreed that C# is the language of choice for developing for the Windows Phone 7. I think it's a safe bet that you won't see VB support if it isn't there already. (Just like XNA... which is up to version 4.0 by now.) So what? (Yeah... I said it.) I think everyone here can agree that actual coding is only one part of software design and development. There is nothing stopping ANY of you from beginning the process of designing your killer phone app, writing up specs, requirements, doing UI design, workflow, mockups, storyboards, art, etc.... None of these things are language dependent. IF by the time you've got that stuff out of the way, and there's still no VB support, then start doing some rapid prototyping of your app in C# (I know, I know... heresy!) You still have to spend time learning how the phone does things, what UI tricks do what, what paradigms make sense, how to use to accelerometer and the tilt and the multitouch functionality. I can guarantee you that time spent doing this is a great investment, no matter WHAT extension your code files have. Eventually, you may have a working prototype. IF by this time, there's STILL no VB support... fret not, you've made significant progress on your app. You've designed it, prototyped it, figured out how to use the phone specific features... so you might as well finish it and pat yourself on the back for learning something new... and possibly being first to market with your new app. I'll be happy to argue any and all of these points online or off with anyone who cares to do so, but there is one undeniable point that you simply can't argue: Your potential customers do not care AT ALL what programming language you used to write the app they are about to purchase. They care that it works. If your biggest concern is being first to market, than stop complaining and get busy because you're running out of time and the 3000+ people who were at MIX certainly aren't waiting for you. They've already started working on their apps.

Data Connection Library in SharePoint Server 2010

- by Wayne

What is a Data Connection Library in SharePoint Server 2010? A Data Connection Library in Microsoft SharePoint Server 2010 is a library that can contain two kinds of data connections: an Office Data Connection (ODC) file or a Universal Data Connection (UDC) file. Microsoft InfoPath 2010 uses data connections that comply with the Universal Data Connection (UDC) file schema and typically have either a *.udcx or *.xml file name extension. Data sources described by these data connections are stored on the server and can be used in standard form templates and browser-enabled form templates. How to create a SharePoint Server Data Connection Library? 1. Browse to a SharePoint Server 2010 site on which you have at least Design permissions. If you are on the root site, create a new site before you continue with the next step. 2. On the Site Actions menu, click More Options. 3. On the Create page, click Library under Filter By, and then click Data Connection Library. 4. On the right side of the Create page, type a name for the library, and then click the Create button. 5. Copy the URL of the new data connection library. How to create a new data connection file in InfoPath? 1. Open InfoPath Designer 2010, click Blank Form, and then click Design Form. 2. On the Data tab, click Data Connections, and then click Add. 3. In the Data Connection Wizard, click Create a new connection to, click Receive data, and then click Next. 4. Click the kind of data source that you are connecting to, such as Database, Web service, or SharePoint library or list, and then click Next. 5. Complete the remaining steps in the Data Connection Wizard to configure your data connection, and then click Finish to return to the Data Connections dialog box. 6. In the Data Connections dialog box, click Convert to Connection File. 7. In the Convert Data Connection dialog box, enter the URL of the data connection library that you previously copied (delete "Forms/AllItems.aspx" and anything following it from the URL), enter a name for the data connection file at the end of the URL, and then click OK. It will take a few moments to convert and save the data connection file to the library. 8. Confirm that the data connection was converted successfully by examining the Details section of the Data Connections dialog box while the name of the converted data connection is selected. 9. Browse to the SharePoint data connection library, click the drop-down next to the name of the data connection, click Approve/Reject, click Approved, and then click OK. Take advantage of SharePoint Data Connection Library and other useful features of SharePoint family of products that include, SharePoint Foundation 2010, MOSS 2007 and free SharePoint templates or web parts.

How to Get Windows 7 Theme Wallpapers Without Installing Them

- by Mysticgeek

Are you using an older version of Windows but like the Windows 7 theme wallpapers? What if you have Windows 7 but you don’t want to install the themes just to get the wallpapers? Here is how to get them without having to install themes. This guest article was written by Ryan Dozier from the Doztech tech blog. Getting the Wallpaper on XP, Vista, or Windows 7 First download and install 7-zip on your machine (link below). After you’ve installed 7-zip, download a Windows 7 theme (link below) and right-click on the theme, select 7-Zip, and Extract to “Theme Name”… A new folder will appear with the theme name on it. When you open it, there will be a folder called DesktopBackground or something similar. Open the folder to get the wallpapers to view the wallpapers for the theme. You can delete the extra files and just keep the wallpapers! Getting the Wallpaper on Ubuntu Extracting the wallpaper on Ubuntu can be a little tricky. Just follow these steps and you will be able to do it. First go to the Ubuntu Software Center under the Applications menu. Search for 7zip and click on the arrow to go to the applications menu. Find the Install button and click it. It will take a couple of minutes for 7zip to install. After 7zip installs, close the Ubuntu Software Center and download a Windows 7 theme. Store it somewhere you can access it quickly. Right-click on the theme and select Rename and get rid of the themepack extension and replace it with zip. The file should be “Theme Name.zip” after you rename it. Right-click on the theme and click Extract Here. After the extracting you will have a new folder with the theme name. Open it and go into the DesktopBackground folder to get the wallpapers. You can delete the extra files and just keep the wallpapers. If you want to get the new Windows 7 Themes Wallpapers, but don’t want to search and install them separately, this is a nice workaround.

Adding Output Caching and Expire Header in IIS7 to improve performance

- by Renso

The problem: Images and other static files will not be cached unless you tell it to. In IIS7 it is remarkably easy to do this. Web pages are becoming increasingly complex with more scripts, style sheets, images, and Flash on them. A first-time visit to a page may require several HTTP requests to load all the components. By using Expires headers these components become cacheable, which avoids unnecessary HTTP requests on subsequent page views. Expires headers are most often associated with images, but they can and should be used on all page components including scripts, style sheets, and Flash. Every time a page is loaded, every image and other static content like JavaScript files and CSS files will be reloaded on every page request. If the content does not change frequently why not cache it and avoid the network traffic?! The solution: In IIS7 there are two ways to cache content, using the web.config file to set caching for all static content, and in IIS7 itself setting aching by file extension that gives you that extra level of granularity. Web.config: In IIS7, Expires Headers can be enabled in the system.webServer section of the web.config file: <staticContent> <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" /> </staticContent> In the above example a cache expiration of 1 day was added. It will be a full day before the content is downloaded from the web server again. To expire the content on a specific date: <staticContent> <clientCache cacheControlMode="UseExpires" httpExpires="Sun, 31 Dec 2011 23:59:59 UTC" /> </staticContent> This will expire the content on December 31st 2011 one second before midnight. Issues/Challenges: Once the file has been set to be cached it wont be updated on the user's browser for the set cache expiration. So be careful here with content that may change frequently, like during development. Typically in development you don't want to cache at all for testing purposes. You could also suffix files with timestamp or versions to force a reload into the user's browser cache. IIS7 Expire Web Content Open up your web app in IIS. Open up the sub-folders until you find the folder or file you want to ad an expiration date to. In IIS6 you used to right-click and select properties, no such luck in IIS7, double click HTTP Response. Once the window loads for the HTTP Response Headers, look to the Actions navigation bar to the right, all the way at the top select SET COMMON HEADERS. The Enable HTTP keep-alive will already be pre-selected. Go ahead and add the appropriate expiration header to the file or folder. Note that if you selected a folder, it will apply that setting to all images inside that folder and all nested content, even subfolders. So, two approaches, depending on what level or granularity you need.

Managing Scripts in Oracle SQL Developer

- by thatjeffsmith

You backup your databases, right? You backup you home computer – your media collection, tax documents, bank accounts, etc, right? You backup your handy-dandy SQL scripts, right? Ok, now that I’ve got your head nodding, I want to answer a question I get every so often: How can I manage my scripts in SQL Developer? This is an interesting question. First, it assumes that one SHOULD manage their scripts in their IDE. Now, what I think the question generally gets around to is, how can we: Navigate to our scripts Open them Execute them What a good IDE should have is an interface to your existing Version Control System (VCS.) SQL Developer supports out-of-the-box both Subversion and Git. You can also download an extension via check-for-updates to get support for CVS. Now, what I’m about to show you COULD be done without versioning and controlling your scripts – but I want to ask you why you wouldn’t want to do this? So, I’m going to proceed and assume that you do INDEED version your scripts already. Seeing what scripts you’ve already got in your repository This is very straightforward – just open the Team Versions panel. Then connect to your repository. Shows you the files in your source control system. Now, I could ‘preview’ said file right away. If I open the file from here, we get a temp file copy down from the server to the local machine. This is a local temp copy of the controlled script – I can read/execute, but not write to it. And that might be all you need. But, if your script calls other scripts, then you’re going to want to check out the server copy of your stuff down your local SVN working copy directory. That way when your script calls another script – you’re executing the PRODUCTION APPROVED copies of said scripts. And if you do SPOOL or other file I/O stuff, it will work as expected. To get to those said client copies of your scripts… Enter the Files Panel The Files panel is accessible from the View menu. You can get to your files, one of two ways. If you’ve touched the file recently, you can see it under the Recent tree. Otherwise, you can navigate to your local ‘checked out’ copies of your script(s). Open your local copies, see what’s changed, etc. And I can access the change history and see what’s been touched… What changes am I going to ‘push out’ if I commit this back to the server? Most of us work on teams, yes? This panel also gives me a heads up if someone else is making changes to the same file. I can see the ‘incoming’ changes as well. To Sum It Up… If I want to get a script to run: do a full get to your local directory open the script(s) The files panel will tell you if your local copy is out of date from the server and if you have made local changes you’ve forgotten to commit back up to the server and your fellow teammates. Now, if you’re the selfish type and don’t want to share, that’s fine. But you should still be backing up your scripts, and you can still use the Files panel to manage your scripts.

[Silverlight] How to watermark a WriteableBitmap with a text

- by Benjamin Roux

Hello, In my current project, I needed to watermark a WriteableBitmap with a text. As I couldn’t find anything I decided to create a small extension method to do so. public static class WriteableBitmapEx { /// <summary> /// Creates a watermark on the specified image /// </summary> /// <param name="input">The image to create the watermark from</param> /// <param name="watermark">The text to watermark</param> /// <param name="color">The color - default is White</param> /// <param name="fontSize">The font size - default is 50</param> /// <param name="opacity">The opacity - default is 0.25</param> /// <param name="hasDropShadow">Specifies if a drop shadow effect must be added - default is true</param> /// <returns>The watermarked image</returns> public static WriteableBitmap Watermark(this WriteableBitmap input, string watermark, Color color = default(Color), double fontSize = 50, double opacity = 0.25, bool hasDropShadow = true) { var watermarked = GetTextBitmap(watermark, fontSize, color == default(Color) ? Colors.White : color, opacity, hasDropShadow); var width = watermarked.PixelWidth; var height = watermarked.PixelHeight; var result = input.Clone(); var position = new Rect(input.PixelWidth - width - 20 /* right margin */, input.PixelHeight - height, width, height); result.Blit(position, watermarked, new Rect(0, 0, width, height)); return result; } /// <summary> /// Creates a WriteableBitmap from a text /// </summary> /// <param name="text"></param> /// <param name="fontSize"></param> /// <param name="color"></param> /// <param name="opacity"></param> /// <param name="hasDropShadow"></param> /// <returns></returns> private static WriteableBitmap GetTextBitmap(string text, double fontSize, Color color, double opacity, bool hasDropShadow) { TextBlock txt = new TextBlock(); txt.Text = text; txt.FontSize = fontSize; txt.Foreground = new SolidColorBrush(color); txt.Opacity = opacity; if (hasDropShadow) txt.Effect = new DropShadowEffect(); WriteableBitmap bitmap = new WriteableBitmap((int)txt.ActualWidth, (int)txt.ActualHeight); bitmap.Render(txt, null); bitmap.Invalidate(); return bitmap; } } For this code to run, you need the WritableBitmapEx library. As you can see, it’s quite simple. You just need to call the Watermark method and pass it the text you want to add in your image. You can also pass optional parameters like the color, the opacity, the fontsize or if you want a drop shadow effect. I could have specify other parameters like the position or the the font family but you can change the code if you need to. Here’s what it can give Hope this helps.

Automated SSRS deployment with the RS utility

- by Stacy Vicknair

If you’re familiar with SSRS and development you are probably aware of the SSRS web services. The RS utility is a tool that comes with SSRS that allows for scripts to be executed against against the SSRS web service without needing to create an application to consume the service. One of the better benefits of using this format rather than writing an application is that the script can be modified by others who might be involved in the creation and addition of scripts or management of the SSRS environment. Reporting Services Scripter Jasper Smith from http://www.sqldbatips.com created Reporting Services Scripter to assist with the created of a batch process to deploy an entire SSRS environment. The helper scripts below were created through the modification of his generated scripts. Why not just use this tool? You certainly can. For me, the volume of scripts generated seems less maintainable than just using some common methods extracted from these scripts and creating a deployment in a single script file. I would, however, recommend this as a product if you do not think that your environment will change drastically or if you do not need to deploy with a higher level of control over the deployment. If you just need to replicate, this tool works great. Executing with RS.exe Executing a script against rs.exe is fairly simple. The Script Half the battle is having a starting point. For the scripting I needed to do the below is the starter script. A few notes: This script assumes integrated security. This script assumes your reports have one data source each. Both of the above are just what made sense for my scenario and are definitely modifiable to accommodate your needs. If you are unsure how to change the scripts to your needs, I recommend Reporting Services Scripter to help you understand how the differences. The script has three main methods: CreateFolder, CreateDataSource and CreateReport. Scripting the server deployment is just a process of recreating all of the elements that you need through calls to these methods. If there are additional elements that you need to deploy that aren’t covered by these methods, again I suggest using Reporting Services Scripter to get the code you would need, convert it to a repeatable method and add it to this script! Public Sub Main() CreateFolder("/", "Data Sources") CreateFolder("/", "My Reports") CreateDataSource("/Data Sources", "myDataSource", _ "Data Source=server\instance;Initial Catalog=myDatabase") CreateReport("/My Reports", _ "MyReport", _ "C:\myreport.rdl", _ True, _ "/Data Sources", _ "myDataSource") End Sub Public Sub CreateFolder(parent As String, name As String) Dim fullpath As String = GetFullPath(parent, name) Try RS.CreateFolder(name, parent, GetCommonProperties()) Console.WriteLine("Folder created: {0}", name) Catch e As SoapException If e.Detail.Item("ErrorCode").InnerText = "rsItemAlreadyExists" Then Console.WriteLine("Folder {0} already exists and cannot be overwritten", fullpath) Else Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End If End Try End Sub Public Sub CreateDataSource(parent As String, name As String, connectionString As String) Try RS.CreateDataSource(name, parent,False, GetDataSourceDefinition(connectionString), GetCommonProperties()) Console.WriteLine("DataSource {0} created successfully", name) Catch e As SoapException Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End Try End Sub Public Sub CreateReport(parent As String, name As String, location As String, overwrite As Boolean, dataSourcePath As String, dataSourceName As String) Dim reportContents As Byte() = Nothing Dim warnings As Warning() = Nothing Dim fullpath As String = GetFullPath(parent, name) 'Read RDL definition from disk Try Dim stream As FileStream = File.OpenRead(location) reportContents = New [Byte](stream.Length-1) {} stream.Read(reportContents, 0, CInt(stream.Length)) stream.Close() warnings = RS.CreateReport(name, parent, overwrite, reportContents, GetCommonProperties()) If Not (warnings Is Nothing) Then Dim warning As Warning For Each warning In warnings Console.WriteLine(Warning.Message) Next warning Else Console.WriteLine("Report: {0} published successfully with no warnings", name) End If 'Set report DataSource references Dim dataSources(0) As DataSource Dim dsr0 As New DataSourceReference dsr0.Reference = dataSourcePath Dim ds0 As New DataSource ds0.Item = CType(dsr0, DataSourceDefinitionOrReference) ds0.Name=dataSourceName dataSources(0) = ds0 RS.SetItemDataSources(fullpath, dataSources) Console.Writeline("Report DataSources set successfully") Catch e As IOException Console.WriteLine(e.Message) Catch e As SoapException Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End Try End Sub Public Function GetCommonProperties() As [Property]() 'Common CatalogItem properties Dim descprop As New [Property] descprop.Name = "Description" descprop.Value = "" Dim hiddenprop As New [Property] hiddenprop.Name = "Hidden" hiddenprop.Value = "False" Dim props(1) As [Property] props(0) = descprop props(1) = hiddenprop Return props End Function Public Function GetDataSourceDefinition(connectionString as String) Dim definition As New DataSourceDefinition definition.CredentialRetrieval = CredentialRetrievalEnum.Integrated definition.ConnectString = connectionString definition.Enabled = True definition.EnabledSpecified = True definition.Extension = "SQL" definition.ImpersonateUser = False definition.ImpersonateUserSpecified = True definition.Prompt = "Enter a user name and password to access the data source:" definition.WindowsCredentials = False definition.OriginalConnectStringExpressionBased = False definition.UseOriginalConnectString = False Return definition End Function Private Function GetFullPath(parent As String, name As String) As String If parent = "/" Then Return parent + name Else Return parent + "/" + name End If End Function

Building ATLAS (and later Octave w/ ATLAS)

- by David Parks

I'm trying to set up ATLAS (so I can later compile octave with ATLAS support). If I'm correct, I still need to build this manually due to the environment specific optimizations. I do see a package for ATLAS, but it looks like it's using the cross platform generic build options (e.g. "it'll be slow"). So, running the configure script as described in the docs seems to go poorly. As a java developer I never do well at making heads or tails of errors in these build processes. Am I missing dependencies (if so is there any documentation on what I need)? allusers@vbubuntu:~/Downloads/atlas3.10.1/build_vbubuntu$ ../configure -b 64 -D c -DPentiumCPS=3000 --with-netlib-lapack-tarfile=/home/allusers/Downloads/lapack-3.5.0.tgz make: `xconfig' is up to date. ./xconfig -d s /home/allusers/Downloads/atlas3.10.1/build_vbubuntu/../ -d b /home/allusers/Downloads/atlas3.10.1/build_vbubuntu -b 64 -D c -DPentiumCPS=3000 -Si lapackref 1 OS configured as Linux (1) Assembly configured as GAS_x8664 (2) Vector ISA Extension configured as SSE3 (6,448) ERROR: enum fam=3, chip=2, mach=0 make[3]: *** [atlas_run] Error 44 make[2]: *** [IRunArchInfo_x86] Error 2 Architecture configured as Corei1 (25) ERROR: enum fam=3, chip=2, mach=0 make[3]: *** [atlas_run] Error 44 make[2]: *** [IRunArchInfo_x86] Error 2 Clock rate configured as 2350Mhz ERROR: enum fam=3, chip=2, mach=0 make[3]: *** [atlas_run] Error 44 make[2]: *** [IRunArchInfo_x86] Error 2 Maximum number of threads configured as 4 Parallel make command configured as '$(MAKE) -j 4' ERROR: enum fam=3, chip=2, mach=0 make[3]: *** [atlas_run] Error 44 make[2]: *** [IRunArchInfo_x86] Error 2 Cannot detect CPU throttling. rm -f config1.out make atlas_run atldir=/home/allusers/Downloads/atlas3.10.1/build_vbubuntu exe=xprobe_comp redir=config1.out \ args="-v 0 -o atlconf.txt -O 1 -A 25 -Si nof77 0 -V 448 -b 64 -d b /home/allusers/Downloads/atlas3.10.1/build_vbubuntu" make[1]: Entering directory `/home/allusers/Downloads/atlas3.10.1/build_vbubuntu' cd /home/allusers/Downloads/atlas3.10.1/build_vbubuntu ; ./xprobe_comp -v 0 -o atlconf.txt -O 1 -A 25 -Si nof77 0 -V 448 -b 64 -d b /home/allusers/Downloads/atlas3.10.1/build_vbubuntu > config1.out make[2]: gfortran: Command not found make[2]: *** [IRunF77Comp] Error 127 make[2]: g77: Command not found make[2]: *** [IRunF77Comp] Error 127 make[2]: f77: Command not found make[2]: *** [IRunF77Comp] Error 127 Unable to find usable compiler for F77; abortingMake sure compilers are in your path, and specify good compilers to configure (see INSTALL.txt or 'configure --help' for details)make[1]: *** [atlas_run] Error 8 make[1]: Leaving directory `/home/allusers/Downloads/atlas3.10.1/build_vbubuntu' make: *** [IRun_comp] Error 2 ERROR 512 IN SYSCMND: 'make IRun_comp args="-v 0 -o atlconf.txt -O 1 -A 25 -Si nof77 0 -V 448 -b 64"' mkdir src bin tune interfaces mkdir: cannot create directory ‘src’: File exists mkdir: cannot create directory ‘bin’: File exists mkdir: cannot create directory ‘tune’: File exists mkdir: cannot create directory ‘interfaces’: File exists make: *** [make_subdirs] Error 1 make -f Make.top startup make[1]: Entering directory `/home/allusers/Downloads/atlas3.10.1/build_vbubuntu' Make.top:1: Make.inc: No such file or directory Make.top:325: warning: overriding commands for target `/AtlasTest' Make.top:76: warning: ignoring old commands for target `/AtlasTest' make[1]: *** No rule to make target `Make.inc'.

Windows Azure Recipe: Social Web / Big Media

- by Clint Edmonson

With the rise of social media there’s been an explosion of special interest media web sites on the web. From athletics to board games to funny animal behaviors, you can bet there’s a group of people somewhere on the web talking about it. Social media sites allow us to interact, share experiences, and bond with like minded enthusiasts around the globe. And through the power of software, we can follow trends in these unique domains in real time. Drivers Reach Scalability Media hosting Global distribution Solution Here’s a sketch of how a social media application might be built out on Windows Azure: Ingredients Traffic Manager (optional) – can be used to provide hosting and load balancing across different instances and/or data centers. Perfect if the solution needs to be delivered to different cultures or regions around the world. Access Control – this service is essential to managing user identity. It’s backed by a full blown implementation of Active Directory and allows the definition and management of users, groups, and roles. A pre-built ASP.NET membership provider is included in the training kit to leverage this capability but it’s also flexible enough to be combined with external Identity providers including Windows LiveID, Google, Yahoo!, and Facebook. The provider model has extensibility points to hook into other identity providers as well. Web Role – hosts the core of the web application and presents a central social hub users. Database – used to store core operational, functional, and workflow data for the solution’s web services. Caching (optional) – as a web site traffic grows caching can be leveraged to keep frequently used read-only, user specific, and application resource data in a high-speed distributed in-memory for faster response times and ultimately higher scalability without spinning up more web and worker roles. It includes a token based security model that works alongside the Access Control service. Tables (optional) – for semi-structured data streams that don’t need relational integrity such as conversations, comments, or activity streams, tables provide a faster and more flexible way to store this kind of historical data. Blobs (optional) – users may be creating or uploading large volumes of heterogeneous data such as documents or rich media. Blob storage provides a scalable, resilient way to store terabytes of user data. The storage facilities can also integrate with the Access Control service to ensure users’ data is delivered securely. Content Delivery Network (CDN) (optional) – for sites that service users around the globe, the CDN is an extension to blob storage that, when enabled, will automatically cache frequently accessed blobs and static site content at edge data centers around the world. The data can be delivered statically or streamed in the case of rich media content. Training These links point to online Windows Azure training labs and resources where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together. It gives developers the choice to build web applications; applications running on connected devices, PCs, or servers; or hybrid solutions offering the best of both worlds. New or enhanced applications can be built using existing skills with the Visual Studio development environment and the .NET Framework. With its standards-based and interoperable approach, the services platform supports multiple internet protocols, including HTTP, REST, SOAP, and plain XML SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. Windows Azure Services (9 labs) As applications collaborate across organizational boundaries, ensuring secure transactions across disparate security domains is crucial but difficult to implement. Windows Azure Services provides hosted authentication and access control using powerful, secure, standards-based infrastructure. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

What DX level does my graphics card support? Does it go to 11?

- by Daniel Moth

Recently I run into a situation that I have run into quite a few times. Someone encounters a machine and the question arises: "Is there a DirectX 11 card in this machine?". Typically the reason you are interested in that is because cards with DirectX 11 drivers fully support DirectCompute (and by extension C++ AMP) for GPGPU programming. The driver specifically is WDDM (1.1 on Windows 7 and Windows 8 introduces WDDM 1.2 with cool new capabilities). There are many ways for figuring out if you have a DirectX11 card, so here are the approaches that you can use, with a bonus right at the end of the post. Run DxDiag WindowsKey + R, type DxDiag and hit Enter. That is the DirectX diagnostic tool, which unfortunately, only tells you on the "System" tab what is the highest version of DirectX installed on your machine. So if it reports DirectX 11, that doesn't mean you have a DX11 driver! The "Display" tab has a promising "DDI version" label, but unfortunately that doesn't seem to be accurate on the machines I've tested it with (or I may be misinterpreting its use). Either way, this tool is not the one you want for this purpose, although it is good for telling you the WDDM version among other things. Use the Microsoft hardware page There is a Microsoft Windows 7 compatibility center, that lists all hardware (tip: use the advanced search) and you could try and locate your device there… good luck. Use Wikipedia or the hardware vendor's website Use the Wikipedia page for the vendor cards, for both nvidia and amd. Often this information will also be in the specifications for the cards on the IHV site, but is is nice that wikipedia has a single page per vendor that you can search etc. There is a column in the tables for API support where you can see the DirectX version. Check if it is one of these recommended DX11 cards You may not have a DirectX 11 card and are interested in purchasing one. While I am in no position to make recommendations, I will list here some cards from two big IHVs that we know are DirectX 11 capable. Some AMD (aka ATI) cards Low end, inexpensive DX11 hardware: Radeon 5450, 5550, 6450, 6570 Mid range (decent perf, single precision): Radeon 5750, 5770, 6770, 6790 High end (capable of double precision): Radeon 5850, 5870, 6950, 6970 Single precision APUs: AMD E-Series APUs AMD A-Series APUs Some NVIDIA cards Low end, inexpensive DX11 hardware: GeForce GT430, GT 440, GT520, GTS 450 Quadro 400, 600 Mid-range (decent perf, single precision): GeForce GTX 460, GTX 550 Ti, GTX 560, GTX 560 Ti Quadro 2000 High end (capable of double precision): GeForce GTX 480, GTX 570, GTX 580, GTX 590, GTX 595 Quadro 4000, 5000, 6000 Tesla C2050, C2070, C2075 Get the DirectX SDK and run DirectX Caps Viewer Download and install the June 2010 DirectX SDK. As part of that you now have the DirectX Capabilities Viewer utility (find it in your start menu by searching for "DirectX Caps Viewer", the filename is DXCapsViewer.exe). It will list all your devices (emulated, and real hardware ones) under the first node. Expand the hardware entries and then expand again the Direct3D 11 folder. If you see D3D_FEATURE_LEVEL_11_ under that, then your card supports feature level 11 which means it supports DirectCompute and C++ AMP. In the following screenshot of one of my old laptops, the card only goes to feature level 10. Run a utility from the web that just tells you! Of course, writing some C++ AMP code that enumerates accelerators and lists the ones that are capable is trivial. However that requires that you have redistributed the runtime, so a more broadly applicable approach is to use the DX APIs directly to enumerate the DX11 capable cards. That is exactly what the development lead for C++ AMP has done and he describes and shares that utility at this post. Comments about this post by Daniel Moth welcome at the original blog.

Custom Templates: Using user exits

- by Anthony Shorten

One of the features of Oracle Utilities Application Framework V4.1 is the ability to use templates and user exits to extend the base configuration files. The configuration files used by the product are based upon a set of templates shipped with the product. When the configureEnv utility asks for configuration settings they are stored in a configuration file ENVIRON.INI which outlines the environment settings. These settings are then used by the initialSetup utility to populate the various configuration files used by the product using templates located in the templates directory of the installation. Now, whilst the majority of the installations at any site are non-production and the templates provided are generally adequate for that need, there are circumstances where extension of templates are needed to take advantage of more advanced facilities (such as advanced security and environment settings). The issue then becomes that if you alter the configuration files manually (directly or indirectly) then you may lose all your custom settings the next time you run initialSetup. To counter this we allow customers to either override templates with their own template or we now provide user exits in the templates to add fragments of configuration unique to that part of the configuration file. The latter means that the base template is still used but additions are included to provide the extensions. The provision of custom templates is supported but as soon as you use a custom template you are then responsible for reflecting any changes we put in the base template over time. Not a big task but annoying if you have to do it for multiple copies of the product. I prefer to use user exits as they seem to represent the least effort solution. The way to find the user exits available is to either read the Server Administration Guide that comes with your product or look at individual templates and look for the lines: #ouaf_user_exit <user exit name> Where <user exit name> is the name of the user exit. User exits are not always present but are in places that we feel are the most likely to be changed. If a user exit does not exist the you can always use a custom template instead. Now lets show an example. By default, the product generates a config.xml file to be used with Oracle WebLogic. This configuration file has the basic setting contained in it to manage the product. If you want to take advantage of the Oracle WebLogic advanced settings, you can use the console to make those changes and it will be reflected in the config.xml automatically. To retain those changes across invocations of initialSetup, you need to alter the template that generates the config.xml or use user exits. The technique is this. Make the change in the console and when you save the change, WebLogic will reflect it in the config.xml for you. Compare the old version and new version of the config.xml and determine what to add and then find the user exit to put it in by examining the base template. For example, by default, the console is not automatically deployed (it is deployed on demand) in the base config.xml. To make the console deploy, you can add the following line to the templates/CM_config.xml.win.exit_3.include file (for windows) or templates/CM_config.xml.exit_3.include file (for linux/unix): <internal-apps-deploy-on-demand-enabled>false</internal-apps-deploy-on-demand-enabled> Now run initialSetup to reflect the change and if you check the splapp/config/config.xml file you will see the change applied for you. Now how did I know which include file? I check the template for config.xml and found there was an user exit at the right place. I prefixed my include filename with "CM_" to denote it as a custom user exit. This will tell the upgrade tools to leave that file alone whenever you decide to upgrade (or even apply fixes). User exits can be powerful and allow customizations to be added for advanced configuration. You will see products using Oracle Utilities Application Framework use this exits themselves (usually prefixed with the product code). You are also taking advantage of them.

Windows Azure Recipe: Consumer Portal

- by Clint Edmonson

Nearly every company on the internet has a web presence. Many are merely using theirs for informational purposes. More sophisticated portals allow customers to register their contact information and provide some level of interaction or customer support. But as our understanding of how consumers use the web increases, the more progressive companies are taking advantage of social web and rich media delivery to connect at a deeper level with the consumers of their goods and services. Drivers Cost reduction Scalability Global distribution Time to market Solution Here’s a sketch of how a Windows Azure Consumer Portal might be built out: Ingredients Web Role – this will host the core of the solution. Each web role is a virtual machine hosting an application written in ASP.NET (or optionally php, or node.js). The number of web roles can be scaled up or down as needed to handle peak and non-peak traffic loads. Database – every modern web application needs to store data. SQL Azure databases look and act exactly like their on-premise siblings but are fault tolerant and have data redundancy built in. Access Control (optional) – if identity needs to be tracked within the solution, the access control service combined with the Windows Identity Foundation framework provides out-of-the-box support for several social media platforms including Windows LiveID, Google, Yahoo!, Facebook. It also has a provider model to allow integration with other platforms as well. Caching (optional) – for sites with high traffic with lots of read-only data and lists, the distributed in-memory caching service can be used to cache and serve up static data at higher scale and speed than direct database requests. It can also be used to manage user session state. Blob Storage (optional) – for sites that serve up unstructured data such as documents, video, audio, device drivers, and more. The data is highly available and stored redundantly across data centers. Each entry in blob storage is provided with it’s own unique URL for direct access by the browser. Content Delivery Network (CDN) (optional) – for sites that service users around the globe, the CDN is an extension to blob storage that, when enabled, will automatically cache frequently accessed blobs and static site content at edge data centers around the world. The data can be delivered statically or streamed in the case of rich media content. Training Labs These links point to online Windows Azure training labs where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together. It gives developers the choice to build web applications; applications running on connected devices, PCs, or servers; or hybrid solutions offering the best of both worlds. New or enhanced applications can be built using existing skills with the Visual Studio development environment and the .NET Framework. With its standards-based and interoperable approach, the services platform supports multiple internet protocols, including HTTP, REST, SOAP, and plain XML SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. Windows Azure Services (9 labs) As applications collaborate across organizational boundaries, ensuring secure transactions across disparate security domains is crucial but difficult to implement. Windows Azure Services provides hosted authentication and access control using powerful, secure, standards-based infrastructure. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

How Do You Actually Model Data?

Since the 1970’s Developers, Analysts and DBAs have been able to represent concepts and relations in the form of data through the use of generic symbols. But what is data modeling? The first time I actually heard this term I could not understand why anyone would want to display a computer on a fashion show runway. Hey, what do you expect? At that time I was a freshman in community college, and obviously this was a long time ago. I have since had the chance to learn what data modeling truly is through using it. Data modeling is a process of breaking down information and/or requirements in to common categories called objects. Once objects start being defined then relationships start to form based on dependencies found amongst other existing objects. Currently, there are several tools on the market that help data designer actually map out objects and their relationships through the use of symbols and lines. These diagrams allow for designs to be review from several perspectives so that designers can ensure that they have the optimal data design for their project and that the design is flexible enough to allow for potential changes and/or extension in the future. Additionally these basic models can always be further refined to show different levels of details depending on the target audience through the use of three different types of models. Conceptual Data Model(CDM)Conceptual Data Models include all key entities and relationships giving a viewer a high level understanding of attributes. Conceptual data model are created by gathering and analyzing information from various sources pertaining to a project during the typical planning phase of a project. Logical Data Model (LDM)Logical Data Models are conceptual data models that have been expanded to include implementation details pertaining to the data that it will store. Additionally, this model typically represents an origination’s business requirements and business rules by defining various attribute data types and relationships regarding each entity. This additional information can be directly translated to the Physical Data Model which reduces the actual time need to implement it. Physical Data Model(PDMs)Physical Data Model are transformed Logical Data Models that include the necessary tables, columns, relationships, database properties for the creation of a database. This model also allows for considerations regarding performance, indexing and denormalization that are applied through database rules, data integrity. Further expanding on why we actually use models in modern application/database development can be seen in the benefits that data modeling provides for data modelers and projects themselves, Benefits of Data Modeling according to Applied Information Science Abstraction that allows data designers remove concepts and ideas form hard facts in the form of data. This gives the data designers the ability to express general concepts and/or ideas in a generic form through the use of symbols to represent data items and the relationships between the items. Transparency through the use of data models allows complex ideas to be translated in to simple symbols so that the concept can be understood by all viewpoints and limits the amount of confusion and misunderstanding. Effectiveness in regards to tuning a model for acceptable performance while maintaining affordable operational costs. In addition it allows systems to be built on a solid foundation in terms of data. I shudder at the thought of a world without data modeling, think about it? Data is everywhere in our lives. Data modeling allows for optimizing a design for performance and the reduction of duplication. If one was to design a database without data modeling then I would think that the first things to get impacted would be database performance due to poorly designed database and there would be greater chances of unnecessary data duplication that would also play in to the excessive query times because unneeded records would need to be processed. You could say that a data designer designing a database is like a box of chocolates. You will never know what kind of database you will get until after it is built.

dynamic? I'll never use that ... or then again, maybe it could ...

- by adweigert

So, I don't know about you, but I was highly skeptical of the dynamic keywork when it was announced. I thought to myself, oh great, just another move towards VB compliance. Well after seeing it being used in things like DynamicXml (which I use for this example) I then was working with a MVC controller and wanted to move some things like operation timeout of an action to a configuration file. Thinking big picture, it'd be really nice to have configuration for all my controllers like that. Ugh, I don't want to have to create all those ConfigurationElement objects... So, I started thinking self, use what you know and do something cool ... Well after a bit of zoning out, self came up with use a dynamic object duh! I was thinking of a config like this ...<controllers> <add type="MyApp.Web.Areas.ComputerManagement.Controllers.MyController, MyApp.Web"> <detail timeout="00:00:30" /> </add> </controllers> So, I ended up with a couple configuration classes like this ...blic abstract class DynamicConfigurationElement : ConfigurationElement { protected DynamicConfigurationElement() { this.DynamicObject = new DynamicConfiguration(); } public DynamicConfiguration DynamicObject { get; private set; } protected override bool OnDeserializeUnrecognizedAttribute(string name, string value) { this.DynamicObject.Add(name, value); return true; } protected override bool OnDeserializeUnrecognizedElement(string elementName, XmlReader reader) { this.DynamicObject.Add(elementName, new DynamicXml((XElement)XElement.ReadFrom(reader))); return true; } } public class ControllerConfigurationElement : DynamicConfigurationElement { [ConfigurationProperty("type", Options = ConfigurationPropertyOptions.IsRequired | ConfigurationPropertyOptions.IsKey)] public string TypeName { get { return (string)this["type"]; } } public Type Type { get { return Type.GetType(this.TypeName, true); } } } public class ControllerConfigurationElementCollection : ConfigurationElementCollection { protected override ConfigurationElement CreateNewElement() { return new ControllerConfigurationElement(); } protected override object GetElementKey(ConfigurationElement element) { return ((ControllerConfigurationElement)element).Type; } } And then had to create the meat of the DynamicConfiguration class which looks like this ...public class DynamicConfiguration : DynamicObject { private Dictionary<string, object> properties = new Dictionary<string, object>(StringComparer.CurrentCultureIgnoreCase); internal void Add<T>(string name, T value) { this.properties.Add(name, value); } public override bool TryGetMember(GetMemberBinder binder, out object result) { var propertyName = binder.Name; result = null; if (this.properties.ContainsKey(propertyName)) { result = this.properties[propertyName]; } return true; } } So all being said, I made a base controller class like a good little MVC-itizen ...public abstract class BaseController : Controller { protected BaseController() : base() { var configuration = ManagementConfigurationSection.GetInstance(); var controllerConfiguration = configuration.Controllers.ForType(this.GetType()); if (controllerConfiguration != null) { this.Configuration = controllerConfiguration.DynamicObject; } } public dynamic Configuration { get; private set; } } And used it like this ...public class MyController : BaseController { static readonly string DefaultDetailTimeout = TimeSpan.MaxValue.ToString(); public MyController() { this.DetailTimeout = TimeSpan.Parse(this.Configuration.Detail.Timeout ?? DefaultDetailTimeout); } public TimeSpan DetailTimeout { get; private set; } } And there I have an actual use for the dynamic keyword ... never thoguht I'd see the day when I first heard of it as I don't do much COM work ... oh dont' forget this little helper extension methods to find the controller configuration by the controller type.public static ControllerConfigurationElement ForType<T>(this ControllerConfigurationElementCollection collection) { Contract.Requires(collection != null); return ForType(collection, typeof(T)); } public static ControllerConfigurationElement ForType(this ControllerConfigurationElementCollection collection, Type type) { Contract.Requires(collection != null); Contract.Requires(type != null); return collection.Cast<ControllerConfigurationElement>().Where(element => element.Type == type).SingleOrDefault(); } Sure, it isn't perfect and I'm sure I can tweak it over time, but I thought it was a pretty cool way to take advantage of the dynamic keyword functionality. Just remember, it only validates you did it right at runtime, which isn't that bad ... is it? And yes, I did make it case-insensitive so my code didn't have to look like my XML objects, tweak it to your liking if you dare to use this creation.

What DX level does my graphics card support? Does it go to 11?

- by Daniel Moth

Recently I run into a situation that I have run into quite a few times. Someone encounters a machine and the question arises: "Is there a DirectX 11 card in this machine?". Typically the reason you are interested in that is because cards with DirectX 11 drivers fully support DirectCompute (and by extension C++ AMP) for GPGPU programming. The driver specifically is WDDM (1.1 on Windows 7 and Windows 8 introduces WDDM 1.2 with cool new capabilities). There are many ways for figuring out if you have a DirectX11 card, so here are the approaches that you can use, with a bonus right at the end of the post. Run DxDiag WindowsKey + R, type DxDiag and hit Enter. That is the DirectX diagnostic tool, which unfortunately, only tells you on the "System" tab what is the highest version of DirectX installed on your machine. So if it reports DirectX 11, that doesn't mean you have a DX11 driver! The "Display" tab has a promising "DDI version" label, but unfortunately that doesn't seem to be accurate on the machines I've tested it with (or I may be misinterpreting its use). Either way, this tool is not the one you want for this purpose, although it is good for telling you the WDDM version among other things. Use the Microsoft hardware page There is a Microsoft Windows 7 compatibility center, that lists all hardware (tip: use the advanced search) and you could try and locate your device there… good luck. Use Wikipedia or the hardware vendor's website Use the Wikipedia page for the vendor cards, for both nvidia and amd. Often this information will also be in the specifications for the cards on the IHV site, but is is nice that wikipedia has a single page per vendor that you can search etc. There is a column in the tables for API support where you can see the DirectX version. Check if it is one of these recommended DX11 cards You may not have a DirectX 11 card and are interested in purchasing one. While I am in no position to make recommendations, I will list here some cards from two big IHVs that we know are DirectX 11 capable. Some AMD (aka ATI) cards Low end, inexpensive DX11 hardware: Radeon 5450, 5550, 6450, 6570 Mid range (decent perf, single precision): Radeon 5750, 5770, 6770, 6790 High end (capable of double precision): Radeon 5850, 5870, 6950, 6970 Single precision APUs: AMD E-Series APUs AMD A-Series APUs Some NVIDIA cards Low end, inexpensive DX11 hardware: GeForce GT430, GT 440, GT520, GTS 450 Quadro 400, 600 Mid-range (decent perf, single precision): GeForce GTX 460, GTX 550 Ti, GTX 560, GTX 560 Ti Quadro 2000 High end (capable of double precision): GeForce GTX 480, GTX 570, GTX 580, GTX 590, GTX 595 Quadro 4000, 5000, 6000 Tesla C2050, C2070, C2075 Get the DirectX SDK and run DirectX Caps Viewer Download and install the June 2010 DirectX SDK. As part of that you now have the DirectX Capabilities Viewer utility (find it in your start menu by searching for "DirectX Caps Viewer", the filename is DXCapsViewer.exe). It will list all your devices (emulated, and real hardware ones) under the first node. Expand the hardware entries and then expand again the Direct3D 11 folder. If you see D3D_FEATURE_LEVEL_11_ under that, then your card supports feature level 11 which means it supports DirectCompute and C++ AMP. In the following screenshot of one of my old laptops, the card only goes to feature level 10. Run a utility from the web that just tells you! Of course, writing some C++ AMP code that enumerates accelerators and lists the ones that are capable is trivial. However that requires that you have redistributed the runtime, so a more broadly applicable approach is to use the DX APIs directly to enumerate the DX11 capable cards. That is exactly what the development lead for C++ AMP has done and he describes and shares that utility at this post. Comments about this post by Daniel Moth welcome at the original blog.

Using T4 to generate Configuration classes

- by Justin Hoffman

I wanted to try to use T4 to read a web.config and generate all of the appSettings and connectionStrings as properties of a class. I elected in this template only to output appSettings and connectionStrings but you can see it would be easily adapted for app specific settings, bindings etc. This allows for quick access to config values as well as removing the potential for typo's when accessing values from the ConfigurationManager. One caveat: a developer would need to remember to run the .tt file after adding an entry to the web.config. However, one would quickly notice when trying to access the property from the generated class (it wouldn't be there). Additionally, there are other options as noted here. The first step was to create the .tt file. Note that this is a basic example, it could be extended even further I'm sure. In this example I just manually input the path to the web.config file. <#@ template debug="false" hostspecific="true" language="C#" #><#@ output extension=".cs" #><#@ assembly Name="System.Configuration" #><#@ assembly name="System.Xml" #><#@ assembly name="System.Xml.Linq" #><#@ assembly name="System.Net" #><#@ assembly name="System" #><#@ import namespace="System.Configuration" #><#@ import namespace="System.Xml" #><#@ import namespace="System.Net" #><#@ import namespace="Microsoft.VisualStudio.TextTemplating" #><#@ import namespace="System.Xml.Linq" #>using System;using System.Configuration;using System.Xml;using System.Xml.Linq;using System.Linq;namespace MyProject.Web { public partial class Configurator { <# var xDocument = XDocument.Load(@"G:\MySolution\MyProject\Web.config"); var results = xDocument.Descendants("appSettings"); const string key = "key"; const string name = "name"; foreach (var xElement in results.Descendants()) {#> public string <#= xElement.Attribute(key).Value#>{get {return ConfigurationManager.AppSettings[<#= string.Format("{0}{1}{2}","\"" , xElement.Attribute(key).Value, "\"")#>];}} <#}#> <# var connectionStrings = xDocument.Descendants("connectionStrings"); foreach(var connString in connectionStrings.Descendants()) {#> public string <#= connString.Attribute(name).Value#>{get {return ConfigurationManager.ConnectionStrings[<#= string.Format("{0}{1}{2}","\"" , connString.Attribute(name).Value, "\"")#>].ConnectionString;}} <#} #> }} The resulting .cs file: using System;using System.Configuration;using System.Xml;using System.Xml.Linq;using System.Linq;namespace MyProject.Web { public partial class Configurator { public string ClientValidationEnabled{get {return ConfigurationManager.AppSettings["ClientValidationEnabled"];}} public string UnobtrusiveJavaScriptEnabled{get {return ConfigurationManager.AppSettings["UnobtrusiveJavaScriptEnabled"];}} public string ServiceUri{get {return ConfigurationManager.AppSettings["ServiceUri"];}} public string TestConnection{get {return ConfigurationManager.ConnectionStrings["TestConnection"].ConnectionString;}} public string SecondTestConnection{get {return ConfigurationManager.ConnectionStrings["SecondTestConnection"].ConnectionString;}} }} Next, I extended the partial class for easy access to the Configuration. However, you could just use the generated class file itself. using System;using System.Linq;using System.Xml.Linq;namespace MyProject.Web{ public partial class Configurator { private static readonly Configurator Instance = new Configurator(); public static Configurator For { get { return Instance; } } }} Finally, in my example, I used the Configurator class like so: [TestMethod] public void Test_Web_Config() { var result = Configurator.For.ServiceUri; Assert.AreEqual(result, "http://localhost:30237/Service1/"); }

Handling "related" work within a single agile work item

- by Tesserex

I'm on a project team of 4 devs, myself included. We've been having a long discussion on how to handle extra work that comes up in the course of a single work item. This extra work is usually things that are slightly related to the task, but not always necessary to accomplish the goal of the item (that may be an opinion). Examples include but are not limited to: refactoring of the code changed by the work item refactoring code neighboring the code changed by the item re-architecting the larger code area around the ticket. For example if an item has you changing a single function, you realize the entire class now could be redone to better accommodate this change. improving the UI on a form you just modified When this extra work is small we don't mind. The problem is when this extra work causes a substantial extension of the item beyond the original feature point estimation. Sometimes a 5 point item will actually take 13 points of time. In one case we had a 13 point item that in retrospect could have been 80 points or more. There are two options going around in our discussion for how to handle this. We can accept the extra work in the same work item, and write it off as a mis-estimation. Arguments for this have included: We plan for "padding" at the end of the sprint to account for this sort of thing. Always leave the code in better shape than you found it. Don't check in half-assed work. If we leave refactoring for later, it's hard to schedule and may never get done. You are in the best mental "context" to handle this work now, since you're waist deep in the code already. Better to get it out of the way now and be more efficient than to lose that context when you come back later. We draw a line for the current work item, and say that the extra work goes into a separate ticket. Arguments include: Having a separate ticket allows for a new estimation, so we aren't lying to ourselves about how many points things really are, or having to admit that all of our estimations are terrible. The sprint "padding" is meant for unexpected technical challenges that are direct barriers to completing the ticket requirements. It is not intended for side items that are just "nice-to-haves". If you want to schedule refactoring, just put it at the top of the backlog. There is no way for us to properly account for this stuff in an estimation, since it seems somewhat arbitrary when it comes up. A code reviewer might say "those UI controls (which you actually didn't modify in this work item) are a bit confusing, can you fix that too?" which is like an hour, but they might say "Well if this control now inherits from the same base class as the others, why don't you move all of this (hundreds of lines of) code into the base and rewire all this stuff, the cascading changes, etc.?" And that takes a week. It "contaminates the crime scene" by adding unrelated work into the ticket, making our original feature point estimates meaningless. In some cases, the extra work postpones a check-in, causing blocking between devs. Some of us are now saying that we should decide some cut off, like if the additional stuff is less than 2 FP, it goes in the same ticket, if it's more, make it a new ticket. Since we're only a few months into using Agile, what's the opinion of all the more seasoned Agile veterans around here on how to handle this?
