  • JD Edwards Apps in a Box - Update

    - by Hartmut Wiese
    Summary and clarification JD Edwards Apps in a box is a Partner offering to the customer. We as Oracle have a huge interest in getting a successful offering to the market and we help the Partner building their offering. We provide components like JD Edwards EnterpriseOne and the Hardware. The Business Partner adds the installation services and position this as a solution to the market for a single price. As you know JD Edwards EnterpriseOne can run on multiple hardware platforms. Linux/X-86 version As you all know we do have JD Edwards VM Templates available from Oracle for the X-86 architecture. Each Partner should or is already able to install JD Edwards EnterpriseOne using these images from our software delivery cloud. We built a master bill of material for a X3-2 Hardware configuration now. It has been uploaded on the Community Workspace now. This is a SUGGESTION and limited to 50 Users MAX. However I strongly recommend you to do a sizing as usual and verify the configuration for each opportunity individually. T4-1/X3-2 version Oracle is not providing similar images for the T4-1 SPARC / SOLARIS architecture. There is an Optimized Solution Team inside Oracle who has created an Optimized Solution for JD Edwards some time ago. They created a whitepaper which is still available to download. This whitepaper was used as a starting point however we decided to build a new version of it using the latest Software and Hardware available. This has now been finalized and we are happy to provide this to our partners. This image is more a service we provide for each partner which they can reuse and extend based on their individual offerings. It is not an official supported Oracle Product and cannot be used to deploy to customers immediately. You cannot resell “JDE in a box”. You can use these images to save time while building your own Go-to-Market offering. You might want to add functionality like Mobility. It is also not complete as also the Deployment Server needs to be configured individually at the customer site. We will create some documentation about: what this images contains (and what not)? what final installation activities needs to be provided by each VAD/Partner in this process?  I will send an email to the community once we are ready to share it. You find these assets than in the Community Workspace. The Business Model with Oracle Hardware For those who have not done any Hardware business with Oracle yet: Usually a HW reseller orders the hardware through a Value Add Distributors (VAD) and not from Oracle directly. Each Partner needs to have Hardware Resell rights to do so. The VAD is assembling the boxes according to the needs of each customer. It is easily possible for them to prepare the boxes with the images we/you provide. However the final configuration is something a reseller/implementer needs to do at the customer site. This process is not the same in the EMEA region. Sometimes a VAD are taking the order but they do not see the Hardware at all. In those cases a VAD cannot provide any help with the pre-loading of any images and the reseller/implementer needs to do that. In some countries we do not have VADs at all.

  • Java Hint in NetBeans for Identifying JOptionPanes

    - by Geertjan
    I tend to have "JOptionPane.showMessageDialogs" scattered through my code, for debugging purposes. Now I have a way to identify all of them and remove them one by one, since some of them are there for users of the application so shouldn't be removed, via the Refactoring window: Identifying instances of code that I'm interested in is really trivial: import org.netbeans.spi.editor.hints.ErrorDescription; import org.netbeans.spi.java.hints.ConstraintVariableType; import org.netbeans.spi.java.hints.ErrorDescriptionFactory; import org.netbeans.spi.java.hints.Hint; import org.netbeans.spi.java.hints.HintContext; import org.netbeans.spi.java.hints.TriggerPattern; import org.openide.util.NbBundle.Messages; @Hint( displayName = "#DN_ShowMessageDialogChecker", description = "#DESC_ShowMessageDialogChecker", category = "general") @Messages({ "DN_ShowMessageDialogChecker=Found \"ShowMessageDialog\"", "DESC_ShowMessageDialogChecker=Checks for JOptionPane.showMes" }) public class ShowMessageDialogChecker { @TriggerPattern(value = "$1.showMessageDialog", constraints = @ConstraintVariableType(variable = "$1", type = "javax.swing.JOptionPane")) @Messages("ERR_ShowMessageDialogChecker=Are you sure you need this statement?") public static ErrorDescription computeWarning(HintContext ctx) { return ErrorDescriptionFactory.forName( ctx, ctx.getPath(), Bundle.ERR_ShowMessageDialogChecker()); } } Stick the above class, which seriously isn't much code at all, in a module and run it, with this result: Bit trickier to do the fix, i.e., add a bit of code to let the user remove the statement, but I looked in the NetBeans sources and used the System.out fix, which does the same thing:  import com.sun.source.tree.BlockTree; import com.sun.source.tree.StatementTree; import com.sun.source.util.TreePath; import java.util.ArrayList; import java.util.Iterator; import java.util.List; import org.netbeans.api.java.source.CompilationInfo; import org.netbeans.api.java.source.WorkingCopy; import org.netbeans.spi.editor.hints.ErrorDescription; import org.netbeans.spi.editor.hints.Fix; import org.netbeans.spi.java.hints.ConstraintVariableType; import org.netbeans.spi.java.hints.ErrorDescriptionFactory; import org.netbeans.spi.java.hints.Hint; import org.netbeans.spi.java.hints.HintContext; import org.netbeans.spi.java.hints.JavaFix; import org.netbeans.spi.java.hints.TriggerPattern; import org.openide.util.NbBundle.Messages; @Hint( displayName = "#DN_ShowMessageDialogChecker", description = "#DESC_ShowMessageDialogChecker", category = "general") @Messages({ "DN_ShowMessageDialogChecker=Found \"ShowMessageDialog\"", "DESC_ShowMessageDialogChecker=Checks for JOptionPane.showMes" }) public class ShowMessageDialogChecker { @TriggerPattern(value = "$1.showMessageDialog", constraints = @ConstraintVariableType(variable = "$1", type = "javax.swing.JOptionPane")) @Messages("ERR_ShowMessageDialogChecker=Are you sure you need this statement?") public static ErrorDescription computeWarning(HintContext ctx) { Fix fix = new FixImpl(ctx.getInfo(), ctx.getPath()).toEditorFix(); return ErrorDescriptionFactory.forName( ctx, ctx.getPath(), Bundle.ERR_ShowMessageDialogChecker(), fix); } private static final class FixImpl extends JavaFix { public FixImpl(CompilationInfo info, TreePath tp) { super(info, tp); } @Override @Messages("FIX_ShowMessageDialogChecker=Remove the statement") protected String getText() { return Bundle.FIX_ShowMessageDialogChecker(); } @Override protected void performRewrite(TransformationContext tc) throws Exception { WorkingCopy wc = tc.getWorkingCopy(); TreePath statementPath = tc.getPath(); TreePath blockPath = tc.getPath().getParentPath(); while (!(blockPath.getLeaf() instanceof BlockTree)) { statementPath = blockPath; blockPath = blockPath.getParentPath(); if (blockPath == null) { return; } } BlockTree blockTree = (BlockTree) blockPath.getLeaf(); List<? extends StatementTree> statements = blockTree.getStatements(); List<StatementTree> newStatements = new ArrayList<StatementTree>(); for (Iterator<? extends StatementTree> it = statements.iterator(); it.hasNext();) { StatementTree statement = it.next(); if (statement != statementPath.getLeaf()) { newStatements.add(statement); } } BlockTree newBlockTree = wc.getTreeMaker().Block(newStatements, blockTree.isStatic()); wc.rewrite(blockTree, newBlockTree); } } } Aside from now being able to use "Inspect & Refactor" to identify and fix all instances of JOptionPane.showMessageDialog at the same time, you can also do the fixes per instance within the editor:

  • LINQ to Twitter Queries with LINQPad

    - by Joe Mayo
    LINQPad is a popular utility for .NET developers who use LINQ a lot.  In addition to standard SQL queries, LINQPad also supports other types of LINQ providers, including LINQ to Twitter.  The following sections explain how to set up LINQPad for making queries with LINQ to Twitter. LINQPad comes in a couple versions and this example uses LINQPad4, which runs on the .NET Framework 4.0. 1. The first thing you'll need to do is set up a reference to the LinqToTwitter.dll. From the Query menu, select query properties. Click the Browse button and find the LinqToTwitter.dll binary. You should see something similar to the Query Properties window below. 2. While you have the query properties window open, add the namespace for the LINQ to Twitter types.  Click the Additional Namespace Imports tab and type in LinqToTwitter. The results are shown below: 3. The default query type, when you first start LINQPad, is C# Expression, but you'll need to change this to support multiple statements.  Change the Language dropdown, on the Main window, to C# Statements. 4. To query LINQ to Twitter, instantiate a TwitterContext, by typing the following into the LINQPad Query window: var ctx = new TwitterContext(); Note: If you're getting syntax errors, go back and make sure you did steps #2 and #3 properly. 5. Next, add a query, but don't materialize it, like this: var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; 6. Next, you want the output to be displayed in the LINQPad grid, so do a Dump, like this: tweets.Dump(); The following image shows the final results:   That was an unauthenticated query, but you can also perform authenticated queries with LINQ to Twitter's support of OAuth.  Here's an example that uses the PinAuthorizer (type this into the LINQPad Query window): var auth = new PinAuthorizer { Credentials = new InMemoryCredentials { ConsumerKey = "", ConsumerSecret = "" }, UseCompression = true, GoToTwitterAuthorization = pageLink => Process.Start(pageLink), GetPin = () => { // this executes after user authorizes, which begins with the call to auth.Authorize() below. Console.WriteLine("\nAfter you authorize this application, Twitter will give you a 7-digit PIN Number.\n"); Console.Write("Enter the PIN number here: "); return Console.ReadLine(); } }; // start the authorization process (launches Twitter authorization page). auth.Authorize(); var ctx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/"); var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; tweets.Dump(); This code is very similar to what you'll find in the LINQ to Twitter downloadable source code solution, in the LinqToTwitterDemo project.  For obvious reasons, I changed the value assigned to ConsumerKey and ConsumerSecret, which you'll have to obtain by visiting http://dev.twitter.com and registering your application. One tip, you'll probably want to make this easier on yourself by creating your own DLL that encapsulates all of the OAuth logic and then call a method or property on you custom class that returns a fully functioning TwitterContext.  This will help avoid adding all this code every time you want to make a query. Now, you know how to set up LINQPad for LINQ to Twitter, perform unauthenticated queries, and perform queries with OAuth. Joe

  • MVC Portable Areas &ndash; Deploying Static Files

    - by Steve Michelotti
    This is the second post in a series related to build and deployment considerations as I’ve been exploring MVC Portable Areas: #1 – Using Web Application Project to build portable areas #2 – Conventions for deploying portable area static files #3 – Portable area static files as embedded resources As I’ve been digging more into portable areas, one of the things I’ve liked best is the deployment story which enables my *.aspx, *.ascx pages to be compiled into the assembly as embedded resources rather than having to maintain all those files separately. In traditional web forms, that was always the thing to prevented developers from utilizing *.ascx user controls across projects (see this post for using portable areas in web forms).  However, though the aspx pages are embedded, the supporting static files (e.g., images, css, javascript) are *not*. Most of the demos available online today tend to brush over this issue and focus solely on the aspx side of things. But to create truly robust portable areas, it’s important to have a good story for these supporting files as well.  I’ve been working with two different approaches so far (of course I’d really like to hear if other people are using alternatives). Scenario For the approaches below, the scenario really isn’t that important. It could be something as trivial as this partial view: 1: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> 2: <img src="<%: Url.Content("~/images/arrow.gif") %>" /> Hello World! The point is that there needs to be careful consideration for *any* scenario that links to an external file such as an image, *.css, *.js, etc. In the example shown above, it uses the Url.Content() method to convert to a relative path. But this method won’t necessary work depending on how you deploy your portable area. One approach to address this issue is to build your portable area project with MSDeploy/WebDeploy so that it is packaged properly before incorporating into the host application. All of the *.cs files are removed and the project is ready for xcopy deployment – however, I do *not* need the “Views” folder since all of the mark up has been compiled into the assembly as embedded resources. Now in the host application we create a folder called “Modules” and deploy any portable areas as sub-folders under that: At this point we can add a simple assembly reference to the Widget1.dll sitting in the Modules\Widget1\bin folder. I can now render the portable image in my view like any other portable area. However, the problem with that is that the view results in this:   It couldn’t find arrow.gif because it looked for /images/arrow.gif and it was *actually* located at /images/Modules/Widget1/images/arrow.gif. One solution is to make the physical location of the portable configurable from the perspective of the host like this: 1: <appSettings> 2: <add key="Widget1" value="Modules\Widget1"/> 3: </appSettings> Using the <appSettings> section is a little cheesy but it could be better formalized into its own section. In fact, if were you willing to rely on conventions (e.g., “Modules\{areaName}”) then then config could be eliminated completely. With this config in place, we could create our own Html helper method called Url.AreaContent() that “wraps” the OOTB Url.Content() method while simply pre-pending the area location path: 1: public static string AreaContent(this UrlHelper urlHelper, string contentPath) 2: { 3: var areaName = (string)urlHelper.RequestContext.RouteData.DataTokens["area"]; 4: var areaPath = (string)ConfigurationManager.AppSettings[areaName]; 5:   6: return urlHelper.Content("~/" + areaPath + "/" + contentPath); With these two items in place, we just change our Url.Content() call to Url.AreaContent() like this: 1: <img src="<%: Url.AreaContent("/images/arrow.gif") %>" /> Hello World! and the arrow.gif now renders correctly:     Since we’re just using our own Url.AreaContent() rather than the built-in Url.Content(), this solution works for images, *.css, *.js, or any externally referenced files.  Additionally, any images referenced inside a css file will work provided it’s a relative reference and not an absolute reference. An alternative to this approach is to build the static file into the assembly as embedded resources themselves. I’ll explore this in another post (linked at the top).

  • Windows Azure Emulators On Your Desktop

    - by BuckWoody
    Many people feel they have to set up a full Azure subscription online to try out and develop on Windows Azure. But you don’t have to do that right away. In fact, you can download the Windows Azure Compute Emulator – a “cloud development environment” – right on your desktop. No, it’s not for production use, and no, you won’t have other people using your system as a cloud provider, and yes, there are some differences with Production Windows Azure, but you’ll be able code, run, test, diagnose, watch, change and configure code without having any connection to the Internet at all. The best thing about this approach is that when you are ready to deploy the code you’ve been testing, a few clicks deploys it to your subscription when you make one.   So what deep-magic does it take to run such a thing right on your laptop or even a Virtual PC? Well, it’s actually not all that difficult. You simply download and install the Windows Azure SDK (you can even get a free version of Visual Studio for it to run on – you’re welcome) from here: http://msdn.microsoft.com/en-us/windowsazure/cc974146.aspx   This SDK will also install the Windows Azure Compute Emulator and the Windows Azure Storage Emulator – and then you’re all set. Right-click the icon for Visual Studio and select “Run as Administrator”:    Now open a new “Cloud” type of project:   Add your Web and Worker Roles that you want to code:   And when you’re done with your design, press F5 to start the desktop version of Azure:   Want to learn more about what’s happening underneath? Right-click the tray icon with the Azure logo, and select the two emulators to see what they are doing:          In the configuration files, you’ll see a “Use Development Storage” setting. You can call the BLOB, Table or Queue storage and it will all run on your desktop. When you’re ready to deploy everything to Windows Azure, you simply change the configuration settings and add the storage keys and so on that you need.   Want to learn more about all this?   Overview of the Windows Azure Compute Emulator: http://msdn.microsoft.com/en-us/library/gg432968.aspx Overview of the Windows Azure Storage Emulator: http://msdn.microsoft.com/en-us/library/gg432983.aspx January 2011 Training Kit: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=413E88F8-5966-4A83-B309-53B7B77EDF78&displaylang=en

  • How to use a list of values in Excel as filter in a query

    - by Luca Zavarella
    It often happens that a customer provides us with a list of items for which to extract certain information. Imagine, for example, that our clients wish to have the header information of the sales orders only for certain orders. Most likely he will give us a list of items in a column in Excel, or, less probably, a simple text file with the identification code:     As long as the given values ??are at best a dozen, it costs us nothing to copy and paste those values ??in our SSMS and place them in a WHERE clause, using the IN operator, making sure to include the quotes in the case of alphanumeric elements (the database sample is AdventureWorks2008R2): SELECT * FROM Sales.SalesOrderHeader AS SOH WHERE SOH.SalesOrderNumber IN ( 'SO43667' ,'SO43709' ,'SO43726' ,'SO43746' ,'SO43782' ,'SO43796') Clearly, the need to add commas and quotes becomes an hassle when dealing with hundreds of items (which of course has happened to us!). It’d be comfortable to do a simple copy and paste, leaving the items as they are pasted, and make sure the query works fine. We can have this commodity via a User Defined Function, that returns items in a table. Simply we’ll provide the function with an input string parameter containing the pasted items. I give you directly the T-SQL code, where comments are there to clarify what was written: CREATE FUNCTION [dbo].[SplitCRLFList] (@List VARCHAR(MAX)) RETURNS @ParsedList TABLE ( --< Set the item length as your needs Item VARCHAR(255) ) AS BEGIN DECLARE --< Set the item length as your needs @Item VARCHAR(255) ,@Pos BIGINT --< Trim TABs due to indentations SET @List = REPLACE(@List, CHAR(9), '') --< Trim leading and trailing spaces, then add a CR\LF at the end of the list SET @List = LTRIM(RTRIM(@List)) + CHAR(13) + CHAR(10) --< Set the position at the first CR/LF in the list SET @Pos = CHARINDEX(CHAR(13) + CHAR(10), @List, 1) --< If exist other chars other than CR/LFs in the list then... IF REPLACE(@List, CHAR(13) + CHAR(10), '') <> '' BEGIN --< Loop while CR/LFs are over (not found = CHARINDEX returns 0) WHILE @Pos > 0 BEGIN --< Get the heading list chars from the first char to the first CR/LF and trim spaces SET @Item = LTRIM(RTRIM(LEFT(@List, @Pos - 1))) --< If the so calulated item is not empty... IF @Item <> '' BEGIN --< ...insert it in the @ParsedList temporary table INSERT INTO @ParsedList (Item) VALUES (@Item) --(CAST(@Item AS int)) --< Use the appropriate conversion if needed END --< Remove the first item from the list... SET @List = RIGHT(@List, LEN(@List) - @Pos - 1) --< ...and set the position to the next CR/LF SET @Pos = CHARINDEX(CHAR(13) + CHAR(10), @List, 1) --< Repeat this block while the upon loop condition is verified END END RETURN END At this point, having created the UDF, our query is transformed trivially in: SELECT * FROM Sales.SalesOrderHeader AS SOH WHERE SOH.SalesOrderNumber IN ( SELECT Item FROM SplitCRLFList('SO43667 SO43709 SO43726 SO43746 SO43782 SO43796') AS SCL) Convenient, isn’t it? You can find the script DBA_SplitCRLFList.sql here. Bye!!

  • Turn off keyboard back-light Sony (VAIO SVF1521DCXW)

    - by KasiyA
    I have a Sony laptop and I want to turn keyboard back-light off. It doesn't have a shortcut function key for doing this on the keyboard .

  • No sound lenovo t60 alsa ad1981 iec958

    - by Nate
    Any help on getting the sound to come through my lenovo t60 build in speakers, headphones, or mic would greatly be appreciated. The three buttons to increase, decrease sound seem to work. Bios has sound card enabled and the buttons beep when pressed. When going to Utube or playing music, no sound is heard. Thanks Nate Feb 23 - Didn't see anything specific in the sys logs with Rhythmbox when connecting my ipod. Rhythmbox is playing, but still no sound. Here is the syslog details for today.

  • Interrupted Upgrade from 11.10 to 12.04

    - by Tamil
    My upgrade using alternative iso from 11.10 to 12.04 got interrupted and I had to hard restart my machine. Now I feel that everything is recovered except my already installed packages like vim.

  • Get Exchange Online Mailbox Size in GB

    - by Brian Jackett
    As mentioned in my previous post I was recently working with a customer to get started with Exchange Online PowerShell commandlets.  In this post I wanted to follow up and show one example of a difference in output from commandlets in Exchange 2010 on-premises vs. Exchange Online.   Problem    The customer was interested in getting the size of mailboxes in GB.  For Exchange on-premises this is fairly easy.  A fellow PFE Gary Siepser wrote an article explaining how to accomplish this (click here).  Note that Gary’s script will not work when remoting from a local machine that doesn’t have the Exchange object model installed.  A similar type of scenario exists if you are executing PowerShell against Exchange Online.  The data type for TotalItemSize  being returned (ByteQuantifiedSize) exists in the Exchange namespace.  If the PowerShell session doesn’t have access to that namespace (or hasn’t loaded it) PowerShell works with an approximation of that data type.    The customer found a sample script on this TechNet article that they attempted to use (minor edits by me to fit on page and remove references to deleted item size.)   Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Select DisplayName,StorageLimitStatus, ` @{name="TotalItemSize (MB)"; expression={[math]::Round( ` ($_.TotalItemSize.Split("(")[1].Split(" ")[0].Replace(",","")/1MB),2)}}, ` ItemCount | Sort "TotalItemSize (MB)" -Descending | Export-CSV "C:\My Documents\All Mailboxes.csv" -NoTypeInformation     The script is targeted to Exchange 2010 but fails for Exchange Online.  In Exchange Online when referencing the TotalItemSize property though it does not have a Split method which ultimately causes the script to fail.   Solution    A simple solution would be to add a call to the ToString method off of the TotalItemSize property (in bold on line 5 below).   Get-Mailbox -ResultSize Unlimited | Get-MailboxStatistics | Select DisplayName,StorageLimitStatus, ` @{name="TotalItemSize (MB)"; expression={[math]::Round( ` ($_.TotalItemSize.ToString().Split("(")[1].Split(" ")[0].Replace(",","")/1MB),2)}}, ` ItemCount | Sort "TotalItemSize (MB)" -Descending | Export-CSV "C:\My Documents\All Mailboxes.csv" -NoTypeInformation      This fixes the script to run but the numerous string replacements and splits are an eye sore to me.  I attempted to simplify the string manipulation with a regular expression (more info on regular expressions in PowerShell click here).  The result is a workable script that does one nice feature of adding a new member to the mailbox statistics called TotalItemSizeInBytes.  With this member you can then convert into any byte level (KB, MB, GB, etc.) that suits your needs.  You can download the full version of this script below (includes commands to connect to Exchange Online session). $UserMailboxStats = Get-Mailbox -RecipientTypeDetails UserMailbox ` -ResultSize Unlimited | Get-MailboxStatistics $UserMailboxStats | Add-Member -MemberType ScriptProperty -Name TotalItemSizeInBytes ` -Value {$this.TotalItemSize -replace "(.*\()|,| [a-z]*\)", ""} $UserMailboxStats | Select-Object DisplayName,@{Name="TotalItemSize (GB)"; ` Expression={[math]::Round($_.TotalItemSizeInBytes/1GB,2)}}   Conclusion    Moving from on-premises to the cloud with PowerShell (and PowerShell remoting in general) can sometimes present some new challenges due to what you have access to.  This means that you must always test your code / scripts.  I still believe that not having to physically RDP to a server is a huge gain over some of the small hurdles you may encounter during the transition.  Scripting is the future of administration and makes you more valuable.  Hopefully this script and the concepts presented help you be a better admin / developer.         -Frog Out     Links The Get-MailboxStatistics Cmdlet, the TotalitemSize Property, and that pesky little “b” http://blogs.technet.com/b/gary/archive/2010/02/20/the-get-mailboxstatistics-cmdlet-the-totalitemsize-property-and-that-pesky-little-b.aspx   View Mailbox Sizes and Mailbox Quotas Using Windows PowerShell http://technet.microsoft.com/en-us/exchangelabshelp/gg576861#ViewAllMailboxes   Regular Expressions with Windows PowerShell http://www.regular-expressions.info/powershell.html   “I don’t always test my code…” image http://blogs.pinkelephant.com/images/uploads/conferences/I-dont-always-test-my-code-But-when-I-do-I-do-it-in-production.jpg   The One Thing: Brian Jackett and SharePoint 2010 http://www.youtube.com/watch?v=Sg_h66HMP9o

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

  • Where to start with game development?

    - by steven_desu
    I asked this earlier in this thread at stackoverflow.com. One of the early comments redirected me here to gamedev.stackexchange.com, so I'm reposting here. Searching for related questions I found a number of very specific questions, but I'm afraid the specifics have proved fruitless for me and after 4 hours on Google I'm no closer than I started, so I felt reaching out to a community might be in order. First, my goal: I've never made a game before, although I've muddled over the possibility several times. I decided to finally sit down and start learning how to code games, use game engines, etc. All so that one day (hopefully soon) I'll be able to make functional (albeit simple) games. I can start adding complexity later, for now I'd be glad to have a keyboard-controlled camera moving in a 3D world with no interaction beyond that. My background: I've worked in SEVERAL programming languages ranging from PHP to C++ to Java to ASM. I'm not afraid of any challenges that come with learning the new syntax or limitations inherent in a new language. All of my past programming experience, however, has been strictly non-graphical and usually with little or extremely simple interaction during execution. I've created extensive and brilliant algorithms for solving logical and mathematical problems as well as graphing problems. However in every case input was either defined in a file, passed form an HTML form, or typed into the console. Real-time interaction with the user is something with which I have no experience. My question: Where should I start in trying to make games? Better yet- where should I start in trying to create a keyboard-navigable 3D environment? In searching online I've found several resources linking to game engines, graphics engines, and physics engines. Here's a brief summary of my experiences with a few engines I tried: Unreal SDK: The tutorial videos assume that you already have in-depth knowledge of 3D modeling, graphics engines, animations, etc. The "Getting Started" page offers no formal explanation of game development but jumps into how Unreal can streamline processes it assumes you're already familiar with. After downloading the SDK and launching it to see if the tools were as intuitive as they claimed, I was greeted with about 60 buttons and a blank void for my 3D modeling. Clicking on "add volume" (to attempt to add a basic cube) I was met with a menu of 30 options. Panicking, I closed the editor. Crystal Space: The website seemed rather informative, explaining that Crystal Space was just for graphics and the companion software, CEL, provided entity logic for making games. A demo game was provided, which was built using "CELStart", their simple tool for people with no knowledge of game programming. I launched the game to see what I might look forward to creating. It froze several times, the menus were buggy, there were thousands of graphical glitches, enemies didn't respond to damage, and when I closed the game it locked up. Gave up on that engine. IrrLicht: The tutorial assumes I have Visual Studio 6.0 (I have Visual Studio 2010). Following their instructions I was unable to properly import the library into Visual Studio and unable to call any of the functions that they kept using. Manually copying header files, class files, and DLLs into my project's folder - the project failed to properly compile. Clearly I'm not off to a good start and I'm going in circles. Can someone point me in the right direction? Should I start by downloading a program like Blender and learning 3D modeling, or should I be learning how to use a graphics engine? Should I look for an all-inclusive game engine, or is it better to try and code my own game logic? If anyone has actually made their own games, I would prefer to hear how they got their start. Also- taking classes at my school is not an option. Nothing is offered.

Clicking on "add volume" (to attempt to add a basic cube) I was met with a menu of 30 options. Panicking, I closed the editor. Crystal Space: The website seemed rather informative, explaining that Crystal Space was just for graphics and the companion software, CEL, provided entity logic for making games. A demo game was provided, which was built using "CELStart", their simple tool for people with no knowledge of game programming. I launched the game to see what I might look forward to creating. It froze several times, the menus were buggy, there were thousands of graphical glitches, enemies didn't respond to damage, and when I closed the game it locked up. Gave up on that engine. IrrLicht: The tutorial assumes I have Visual Studio 6.0 (I have Visual Studio 2010). Following their instructions I was unable to properly import the library into Visual Studio and unable to call any of the functions that they kept using. Manually copying header files, class files, and DLLs into my project's folder - the project failed to properly compile. Clearly I'm not off to a good start and I'm going in circles. Can someone point me in the right direction? Should I start by downloading a program like Blender and learning 3D modeling, or should I be learning how to use a graphics engine? Should I look for an all-inclusive game engine, or is it better to try and code my own game logic? If anyone has actually made their own games, I would prefer to hear how they got their start. Also- taking classes at my school is not an option. Nothing is offered.

  • Create and Track Your Own License Keys with PowerShell

    - by BuckWoody
    SQL Server used to have  cool little tool that would let you track your licenses. Microsoft didn’t use it to limit your system or anything, it was just a place on the server where you could put that this system used this license key. I miss those days – we don’t track that any more, and I want to make sure I’m up to date on my licensing, so I made my own. Now, there are a LOT of ways you could do this. You could add an extended property in SQL Server, add a table to a tracking database, use a text file, track it somewhere else, whatever. This is just the route I chose; if you want to use some other method, feel free. Just sharing here. Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. And this is REALLY important. I include a disclaimer at the end of my scripts, but in this case you’re modifying your registry, and that could be EXTREMELY dangerous – only do this on a test server – and I’m just showing you how I did mine. It isn’t an endorsement or anything like that, and this is a “Buck Woody” thing, NOT a Microsoft thing. See this link first, and then you can read on. OK, here’s my script: # Track your own licenses # Write a New Key to be the License Location mkdir HKCU:\SOFTWARE\Buck   # Write the variables - one sets the type, the other sets the number, and the last one holds the key New-ItemProperty HKCU:\SOFTWARE\Buck -name "SQLServerLicenseType" -value "Processor" # Notice the Dword value here - this one is a number so it needs that. Keep this on one line! New-ItemProperty HKCU:\SOFTWARE\Buck -name "SQLServerLicenseNumber" -propertytype DWord -value 4 New-ItemProperty HKCU:\SOFTWARE\Buck -name "SQLServerLicenseKey" -value "ABCD1234"   # Read them all $LicenseKey = Get-Item HKCU:\Software\Buck $Licenses = Get-ItemProperty $LicenseKey.PSPath foreach ($License in $LicenseKey.Property) { $License + "=" + $Licenses.$License }   Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. Yes, there are always multiple ways to do things, and this script may not work in every situation, for everything. It’s just a script, people. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary. Void where prohibited. Offer good for a limited time only. Keep out of reach of small children. Do not operate heavy machinery while using this script.

  • Using Oracle Linux iSCSI targets with Oracle VM

    - by wim.coekaerts
    A few days ago I had written a blog entry on how to use Oracle Solaris 10 (in my case), ZFS and the iSCSI target feature in Oracle Solaris to create a set of devices exported to my Oracle VM server. Oracle Linux can do this as well and I wanted to make sure I also tried out how to do this on Oracle Linux and here are the results. When you install Oracle Linux 5 update 5 (anything newer than update 3), it comes with an rpm called scsi-target-utils. To begin your quest, should you choose to accept it :) make sure this is installed. rpm -qa |grep scsi-target If it is not installed : up2date scsi-target-utils The target utils come with a tool tgtadm which is similar to iscsitadm on Oracle Solaris. There are 2 components again on the iSCSI server side. (1) create volumes - we will use lvm with lvcreate (2) expose a target using tgtadm. My server has a simple setup. All the disks are part of a single volume group called vgroot. To export a 50Gb volume I just create a new volume : lvcreate -L 50G -nmytest1 vgroot This will show up as a new volume in /dev/mapper as /dev/mapper/vgroot-mytest1. Create as many as you want for your environment. Since I already have my blog entry about the 5 volumes, I am not going to repeat the whole thing. You can just go look at the previous blog entry. Now that we have created the volume, we need to use tgtadm to set it up : make sure the service is running : /etc/init.d/tgtd start or service tgtd start (if you want to keep it running you can do chkconfig tgtd on to start it automatically at boottime) Next you need a targetname to set everything up. My recommendation would be to install iscsi-initiator-utils . This will create an iscsi id and put it in /etc/iscsi/initiatorname.iscsi. For convenience you can do : source /etc/iscsi/initiatorname.iscsi echo $InitiatorName and from here on use $InitiatorName instead of the long complex iqn. create your target : tgtadm --lld iscsi --op new --mode target --tid 1 -T $InitiatorName to show the status : tgtadm --lld iscsi --op show --mode target add the volume previously created : tgtadm --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/mapper/vgroot-mytest1 re-run status to see it's there : tgtadm --lld iscsi --op show --mode target and just like on Oracle Solaris you now have to export (bind) it : tgtadm --lld iscsi --op bind --mode target --tid 1 -I iqn.1986-03.com.sun:01:2a7526f0ffff If you want to export the lun to every iscsi initiator then replace the iqn with ALL. Of course you have to add the iqn of each iscsi initiator or client you want to connect. In the case of my 2 node Oracle VM server setup, both Oracle VM server's initiator names would have to be added. use status again to see that it has this iqn under ACL tgtadm --lld iscsi --op show --mode target You can drop the --lld iscsi if you want, or alias it. It just makes the command line more obvious as to what you are doing. Oracle VM side : Refer back to the previous blog entry for the detailed setup of my Oracle VM server volumes but the exact same commands will be used there. discover : iscsiadm --mode discovery --type sendtargets --portal login : iscsiadm --mode node --targetname iscsi targetname --portal --login get devices : /etc/init.d/iscsi restart and voila you should be in business. have fun.

  • Implementing Search for BlogReader Windows 8 Sample

    - by Harish Ranganathan
    The BlogReader sample is an excellent place to start speeding up your Windows 8 development skills.  The tutorial is available here and the complete source code is available here Create a project called WindowsBlogReader and create pages for ItemsPage.xaml, SplitPage.xaml and DetailPage.xaml and copy the corresponding code blocks from the sample listed above. Created a class file FeedData.cs and copy the code.  Finally, create a class DateConverter.cs and copy the code associated with it. With that you should be able to build and run the project.  There seems to be one issue in the sample feeds listed that the first week (feed1) doesn’t seem to expose it.  So you can skip that and use the second feed as first feed.  You will end up with one feed less but it works. I had demonstrated this in the recent TechDays at Chennai.  How we can use the Search Contract and implement Search for within the Blog Titles. First off, we need to declare that the App will be using Search Contract, in the Package.appmanifest file Next, we would need a handle of the Search Contract when user types on the search window in Charms Menu. If you had completed the code sample from the link above, you would have ItemsPage.xaml and ItemsPage.xaml.cs.  Open the ItemsPage.xaml.cs. Import the namespaces using System.Collections.ObjectModel and System.Linq. in the ItemsPage() constructor, right after this.InitializeComponent(); add the following code Windows.ApplicationModel.Search.SearchPane.GetForCurrentView().QuerySubmitted += ItemsPage_QuerySubmitted; This event is fired when users open up the Search Panel from Charms Menu, type something and hit enter. We need to handle this event declared in the delegate.  For that we need to pull the FeedDataSource instantiation to the root of the class to make it global. So, add the following as the first line within the partial class FeedDataSource feedDataSource; Also, modify the LoadState method, as follows:- protected override void LoadState(Object navigationParameter, Dictionary<String, Object> pageState)        {            feedDataSource = (FeedDataSource)App.Current.Resources["feedDataSource"];            if (feedDataSource != null)            {                this.DefaultViewModel["Items"] = feedDataSource.Feeds;            }        } Next is to implement the ItemsPage_QuerySubmitted method void ItemsPage_QuerySubmitted(Windows.ApplicationModel.Search.SearchPane sender, Windows.ApplicationModel.Search.SearchPaneQuerySubmittedEventArgs args)         {             this.DefaultViewModel["Items"] = from dynamic item in feedDataSource.Feeds                                              where                                              item.Title.Contains(args.QueryText)                                              select item;         } As you can see we are almost using the same defaultviewmodel with the change that we are using a linq query to do a search on feeds which has the Title that matches QueryText. With this we are ready to run the app. Run the App.  Hit the Charms Menu with Windows + C key combination and type a text to search within the blog. You can see that it filters the Blogs which has the matching text. We can modify the above Linq query to do a search for the Text in other attributes like description, actual blog content etc., I have uploaded the complete code since the original WindowsBlogReader Code is not available for download.  You can download it from here note:  this code is provided as-is without any warranties.  Cheers!!!

  • Copying A Slide From One Presentation To Another

    - by Tim Murphy
    There are many ways to generate a PowerPoint presentation using Open XML.  The first way is to build it by hand strictly using the SDK.  Alternately you can modify a copy of a base presentation in place.  The third approach to generate a presentation is to build a new presentation from the parts of an existing presentation by copying slides as needed.  This post will focus on the third option. In order to make this solution a little more elegant I am going to create a VSTO add-in as I did in my previous post.  This one is going to insert Tags to identify slides instead of NonVisualDrawingProperties which I used to identify charts, tables and images.  The code itself is fairly short. SlideNameForm dialog = new SlideNameForm(); Selection selection = Globals.ThisAddIn.Application.ActiveWindow.Selection;   if(dialog.ShowDialog() == DialogResult.OK) { selection.SlideRange.Tags.Add(dialog.slideName,dialog.slideName); } Zeyad Rajabi has a good post here on combining slides from two presentations.  The example he gives is great if you are doing a straight merge.  But what if you want to use your source file as almost a supermarket where you pick and chose slides and may even insert them repeatedly?  The following code uses the tags we created in the previous step to pick a particular slide an copy it to a destination file. using (PresentationDocument newDocument = PresentationDocument.Open(OutputFileText.Text,true)) { PresentationDocument templateDocument = PresentationDocument.Open(FileNameText.Text, false);   uniqueId = GetMaxIdFromChild(newDocument.PresentationPart.Presentation.SlideMasterIdList); uint maxId = GetMaxIdFromChild(newDocument.PresentationPart.Presentation.SlideIdList);   SlidePart oldPart = GetSlidePartByTagName(templateDocument, SlideToCopyText.Text);   SlidePart newPart = newDocument.PresentationPart.AddPart<SlidePart>(oldPart, "sourceId1");   SlideMasterPart newMasterPart = newDocument.PresentationPart.AddPart(newPart.SlideLayoutPart.SlideMasterPart);   SlideIdList idList = newDocument.PresentationPart.Presentation.SlideIdList;   // create new slide ID maxId++; SlideId newId = new SlideId(); newId.Id = maxId; newId.RelationshipId = "sourceId1"; idList.Append(newId);   // Create new master slide ID uniqueId++; SlideMasterId newMasterId = new SlideMasterId(); newMasterId.Id = uniqueId; newMasterId.RelationshipId = newDocument.PresentationPart.GetIdOfPart(newMasterPart); newDocument.PresentationPart.Presentation.SlideMasterIdList.Append(newMasterId);   // change slide layout ID FixSlideLayoutIds(newDocument.PresentationPart);     //newPart.Slide.Save(); newDocument.PresentationPart.Presentation.Save(); } The GetMaxIDFromChild and FixSlideLayoutID methods are barrowed from Zeyad’s article.  The GetSlidePartByTagName method is listed below.  It is really one LINQ query that finds SlideParts with child Tags that have the requested Name. private SlidePart GetSlidePartByTagName(PresentationDocument templateDocument, string tagName) { return (from p in templateDocument.PresentationPart.SlideParts where p.UserDefinedTagsParts.First().TagList.Descendants <DocumentFormat.OpenXml.Presentation.Tag>().First().Name == tagName.ToUpper() select p).First(); } This is what really makes the difference from what Zeyad posted.  The most powerful thing you can have when generating documents from templates is a consistent way of naming items to be manipulated.  I will be show more approaches like this in upcoming posts. del.icio.us Tags: Office Open XML,Presentation,PowerPoint,VSTO,TagList

  • Debugging .NET code called from X++ code in AX 2012

    - by ssmantha
    A very intriguing issue came to me to debug .Net code called from X++ code in AX 2012. This was indeed a challenge to be nailed down. Luckily the tools and some concepts helped me to achieve this task. Here it goes... We need to do a seamless debugging from AX debugger to Visual Studio back and forth. To enable this we need to first see if the dll to be debug is present in GAC then we might need to uninstall it from it due to the order of preference .NET loads the assemblies. The assemblies are first loaded from GAC and then the runtime checks for Public and Private Assemblies. Since the assembly in GAC is always compiled with runtime optimizations it is difficult to debug. We need to unhook this assembly from GAC and then move further relying on >NET assembly loading patterns. Step 1: Remove the target assembly to debug from GAC. Before that stop all the AOS servers and close all the instances of programs which rely on AOT e.g. all clients and even visual studio now. Step 2: Build your sample code which is present in AOT in debug mode and get the dll file along with PDB files. Step 3: Place these files in the Server\..\Bin and Client\bin directories of AX installation. Step 4: Configure Visual Studio: Step 4.1: Configure Debugging Options. In Visual Studio Go to Debug -> Options and Settings -> Debug node -> General sub node and disable “Enable Just My Code (managed)” Step 4.2: Specify the symbol loading directory options. Specify the locations for Client bin and server bin directories of the installation, remember to specify the correct instance of Server bin directory corresponding to your AOS. Step 4.3: Configure the project for debugging Step 5: Ready to go place your breakpoints in X++ and in .Net wherever necessary before this process... Run the Visual studio project and it will invoke the AX client with your breakpoint hitting X++ code.. and when you do a step-in using F11 the Visual studio debugger will be active and from here onwards you would be able to debug the complete flow. Debugging in seamless manner across debuggers is really very good feature and mostly underutilized, but by doing so we can have improved troubleshooting and saves a hell lot of time.. Stay tuned for more in Advanced Debugging..

  • The WaitForAll Roadshow

    - by adweigert
    OK, so I took for granted some imaginative uses of WaitForAll but lacking that, here is how I am using. First, I have a nice little class called Parallel that allows me to spin together a list of tasks (actions) and then use WaitForAll, so here it is, WaitForAll's 15 minutes of fame ... First Parallel that allows me to spin together several Action delegates to execute, well in parallel.   public static class Parallel { public static ParallelQuery Task(Action action) { return new Action[] { action }.AsParallel(); } public static ParallelQuery> Task(Action action) { return new Action[] { action }.AsParallel(); } public static ParallelQuery Task(this ParallelQuery actions, Action action) { var list = new List(actions); list.Add(action); return list.AsParallel(); } public static ParallelQuery> Task(this ParallelQuery> actions, Action action) { var list = new List>(actions); list.Add(action); return list.AsParallel(); } }   Next, this is an example usage from an app I'm working on that just is rendering some basic computer information via WMI and performance counters. The WMI calls can be expensive given the distance and link speed of some of the computers it will be trying to communicate with. This is the actual MVC action from my controller to return the data for an individual computer.  public PartialViewResult Detail(string computerName) { var computer = this.Computers.Get(computerName); var perf = Factory.GetInstance(); var detail = new ComputerDetailViewModel() { Computer = computer }; try { var work = Parallel .Task(delegate { // Win32_ComputerSystem var key = computer.Name + "_Win32_ComputerSystem"; var system = this.Cache.Get(key); if (system == null) { using (var impersonation = computer.ImpersonateElevatedIdentity()) { system = computer.GetWmiContext().GetInstances().Single(); } this.Cache.Set(key, system); } detail.TotalMemory = system.TotalPhysicalMemory; detail.Manufacturer = system.Manufacturer; detail.Model = system.Model; detail.NumberOfProcessors = system.NumberOfProcessors; }) .Task(delegate { // Win32_OperatingSystem var key = computer.Name + "_Win32_OperatingSystem"; var os = this.Cache.Get(key); if (os == null) { using (var impersonation = computer.ImpersonateElevatedIdentity()) { os = computer.GetWmiContext().GetInstances().Single(); } this.Cache.Set(key, os); } detail.OperatingSystem = os.Caption; detail.OSVersion = os.Version; }) // Performance Counters .Task(delegate { using (var impersonation = computer.ImpersonateElevatedIdentity()) { detail.AvailableBytes = perf.GetSample(computer, "Memory", "Available Bytes"); } }) .Task(delegate { using (var impersonation = computer.ImpersonateElevatedIdentity()) { detail.TotalProcessorUtilization = perf.GetValue(computer, "Processor", "% Processor Time", "_Total"); } }).WithExecutionMode(ParallelExecutionMode.ForceParallelism); if (!work.WaitForAll(TimeSpan.FromSeconds(15), task => task())) { return PartialView("Timeout"); } } catch (Exception ex) { this.LogException(ex); return PartialView("Error.ascx"); } return PartialView(detail); }

  • Using the latest (stable release) of Oracle Developer Tools for Visual Studio 11.1.0.7.20.

    - by mbcrump
    +  = Simple and safe Data connections.   This guide is for someone wanting to use the latest ODP.NET quickly without reading the official documentation. This guide will get you up and running in about 15 minutes. I have reviewed my referral link to my simple Setting up ODP.net with Win7 x64 and noticed most people were searching for one of the following terms: “how to use odp.net with vs” “setup connection odp.net” “query db using odp and vs” While my article provided links and a sample tnsnames.ora file, it really didn’t tell you how to use it. I’m hoping that this brief tutorial will help. So before we get started, you will need the following: Download the following: www.oracle.com/technology/software/tech/dotnet/utilsoft.html from oracle and install it. It is the first one on the page. Visual Studio 2008 or 2010. It should be noted that The System.Data.OracleClient namespace is the OLD .NET Framework Data Provider for Oracle. It should not be used anymore as it has been depreciated. The latest version which is what we are using is Oracle.DataAccess.Client. First things first, Add a reference to the Oracle.DataAccess.Client after you install ODP.NET   Copy and paste the following C# code into your project and replace the relevant info including the query string and you should be able to return data. I have commented several lines of code to assist in understanding what it is doing.   Lambda Expression. using System; using System.Data; using Oracle.DataAccess.Client;   namespace ConsoleApplication1 {     class Program     {         static void Main(string[] args)         {           try         {             //Setup DataSource             string oradb = "Data Source=(DESCRIPTION ="                                    + "(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = hostname)(PORT = 1521)))"                                    + "(CONNECT_DATA = (SERVICE_NAME = SERVICENAME))) ;"                                    + "Persist Security Info=True;User ID=USER;Password=PASSWORD;";                        //Open Connection to Oracle - this could be moved outside the try.             OracleConnection conn = new OracleConnection(oradb);             conn.Open();               //Create cmd and use parameters to prevent SQL injection attacks.             OracleCommand cmd = new OracleCommand();             cmd.Connection = conn;               cmd.CommandText = "select username from table where username = :username";               OracleParameter p1 = new OracleParameter("username", OracleDbType.Varchar2);             p1.Value = username;             cmd.Parameters.Add(p1);               cmd.CommandType = CommandType.Text;               OracleDataReader dr = cmd.ExecuteReader();             dr.Read();               //Contains the value of the datarow             Console.WriteLine(dr["username"].ToString());               //Disposes of objects.             dr.Dispose();             cmd.Dispose();             conn.Dispose();         }           catch (OracleException ex) // Catches only Oracle errors         {             switch (ex.Number)             {                 case 1:                     Console.WriteLine("Error attempting to insert duplicate data.");                     break;                 case 12545:                     Console.WriteLine("The database is unavailable.");                     break;                 default:                     Console.WriteLine(ex.Message.ToString());                     break;             }         }           catch (Exception ex) // Catches any error not previously caught         {                   Console.WriteLine("Unidentified Error: " + ex.Message.ToString());              }         }       }           } At this point, you should have a working Program that returns data from an oracle database. If you are still having trouble then drop me a line and I will be happy to assist. As of this writing, oracle has announced the latest beta release of ODP.NET 11.2.0.1.1 Beta.  This release includes .NET Framework 4 and .NET Framework 4 Client Profile support. You may want to hold off on this version for a while as its BETA, and I wouldn’t want any production code using any BETA software.

Time to become a meteorologist. To be honest I don’t know how to start. Is cloud better or worse than on campus resources … hmm … it is just different. I think for successful adoption in cloud world IT Dinosaurs need to forget some “Private Cloud” virtualization bad habits, and learn new way of thinking. Take a look: - I don’t need any  tapes or  CDs  (Physical Kingdom of Windows XP and 2000) - I don’t need any locally stored MP3s (CD virtualization :-) - I can just stream music to your computer no matter whether my on-site infrastructure is powered on. Why not to do exactly the same with WebServer, SQL, or just rented for a while Windows server ? Let’s go, to the other side of the mirror. 1st  - register yourself for free one month trial, as happy MSDN subscriber you’ve got monthly budget to spent. In addition in default setting your limit protects you against loosing real money, if your toys will consume too much traffic and space. http://azure.microsoft.com/en-us/pricing/free-trial/ Once your account is ready forget WebPortal, we are PowerShell knights. http://go.microsoft.com/?linkid=9811175&clcid=0x409 #Authenticate yourself in Azure Add-AzureAccount #download once your settings file Get-AzurePublishSettingsFile #Import it to your PowerShell Module Import-AzurePublishSettingsFile "C:\Azure\[filename].publishsettings" #validation Get-AzureAccount Get-AzureSubscription #where are Azure datacenters Get-AzureLocation #You will need it Update-Help #storage account is related to physical location, there are two datacenters on each continent, try nearest to you # all your VMs will store VHD files on your storage account #your storage account must be unique globally, so I assume that words account or server are already used New-AzureStorageAccount -StorageAccountName "[YOUR_STORAGE_ACCOUNT]" -Label "AzureTwo" -Location "West Europe" Get-AzureStorageAccount #it looks like you are ready to deploy first VM, what templates we can use Get-AzureVMImage | Select ImageName #what a mess, let’s choose Server 2012 $ImageName = (Get-AzureVMImage)[74].ImageName $cloudSvcName = '[YOUR_STORAGE_ACCOUNT]' $AdminUsername = "[YOUR-ADMIN]" $adminPassword = '[YOUR_PA$$W0RD]' $MediaLocation = "West Europe" $vmnameDC = 'DC01' #burn baby burn !!! $vmDC01 = New-AzureVMConfig -Name $vmnameDC -InstanceSize "Small" -ImageName $ImageName   `     | Add-AzureProvisioningConfig -Windows -Password $adminPassword -AdminUsername $AdminUsername   `     | New-AzureVM -ServiceName $cloudSvcName #ice, ice baby … Get-AzureVM Get-AzureRemoteDesktopFile -ServiceName "[YOUR_STORAGE_ACCOUNT]" -Name "DC01" -LocalPath "c:\AZURE\DC01.rdp" As you can see it is not just a new-VM, you need to associate your VM with AzureVMConfig (it sets your template), AzureProvisioningConfig (it sets your customizations), and Storage account. In next releases you’ll need to put this machine in specific subnet, attach a HDD and many more. After second reading I found that I am using the same name for STORAGE and SERVICE account, please be aware of it if you need to split these values. Conclusions: - pipe rules ! - at the beginning it is hard to change your mind and agree with fact that it is easier to remove and recreate a VM than move it to different subnet - by default everything is firewalled, limited access to DNS, but NATed outside on custom ports. It is good to check these translations sometimes on the webportal. - if you remove your VMs your harddrives remains on storage and MS will charge you . Remove-AzureVM -DeleteVHD For me AZURE it is a lot of fun, once again I can be newbie and learn every page.

  • How to create array with unique sprites? in cocos2d iphone

    - by prakash s
    I write the code like this. This displays only one sprite (red colour bubble) with number of times and moving down, but actually I want to display different sprites (different colour bubble) every time and moving down. I also add no of .png images in resource folder of my project. Here I used only 3.png, but I need to display all *.png images (different colour bubbles) in my project but I don't know how to get this. Please help me Thank you. Here is the code: -(void)addTarget { CCSprite *target = [CCSprite spriteWithFile:@"3.png" rect:CGRectMake(0, 0, 256, 256)]; CGSize winSize = [[CCDirector sharedDirector] winSize]; int minY = target.contentSize.height/2; int maxY = winSize.height - target.contentSize.height/2; int rangeY = maxY - minY; int actualY = (arc4random() % rangeY) + minY; // Create the target slightly off-screen along the right edge, // and along a random position along the Y axis as calculated above target.position = ccp(winSize.width + (target.contentSize.width/2), actualY); [self addChild:target]; // Determine speed of the target int minDuration = 4.0; int maxDuration = 12.0; int rangeDuration = maxDuration - minDuration; int actualDuration = (arc4random() % rangeDuration) + minDuration; // Create the actions id actionMove = [CCMoveTo actionWithDuration:actualDuration position:ccp(-target.contentSize.width/2,actualY)]; id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)]; [target runAction:[CCSequence actions:actionMove, actionMoveDone, nil]]; // Add to targets array target.tag = 2; [_targets addObject:target]; } -(void)gameLogic:(ccTime)dt { [self addTarget]; } -(id) init { if( (self=[super initWithColor:ccc4(255,255,255,255)] )) { // Enable touch events self.isTouchEnabled = YES; // Initialize arrays _targets = [[NSMutableArray alloc] init]; _projectiles = [[NSMutableArray alloc] init]; // Get the dimensions of the window for calculation purposes CGSize winSize = [[CCDirector sharedDirector] winSize]; [self schedule:@selector(gameLogic:) interval:1.0]; [self schedule:@selector(update:)]; } return self; } - (void)update:(ccTime)dt { NSMutableArray *projectilesToDelete = [[NSMutableArray alloc] init]; for (CCSprite *projectile in _projectiles) { CGRect projectileRect = CGRectMake(projectile.position.x - (projectile.contentSize.width/2), projectile.position.y - (projectile.contentSize.height/2), projectile.contentSize.width, projectile.contentSize.height); NSMutableArray *targetsToDelete = [[NSMutableArray alloc] init]; for (CCSprite *target in _targets) { CGRect targetRect = CGRectMake(target.position.x - (target.contentSize.width/2), target.position.y - (target.contentSize.height/2), target.contentSize.width, target.contentSize.height); if (CGRectIntersectsRect(projectileRect, targetRect)) { [targetsToDelete addObject:target]; } } for (CCSprite *target in targetsToDelete) { [_targets removeObject:target]; [self removeChild:target cleanup:YES]; _projectilesDestroyed++; if (_projectilesDestroyed > 30) { //GameOverScene *gameOverScene = [GameOverScene node]; // [gameOverScene.layer.label setString:@"You Win!"]; // [[CCDirector sharedDirector] replaceScene:gameOverScene]; } } if (targetsToDelete.count > 0) { [projectilesToDelete addObject:projectile]; } [targetsToDelete release]; } for (CCSprite *projectile in projectilesToDelete) { [_projectiles removeObject:projectile]; [self removeChild:projectile cleanup:YES]; } [projectilesToDelete release]; }
