  • What Will Happen to Real Estate Leases when Operating Leases are Gone?

    - by Theresa Hickman
    Many people are concerned about what will happen to real estate leases when FASB and IASB abolish operating leases. They plan to unveil the proposed standards on treating leases this summer as part of the convergence project but no "finalized ruling" is expected for at least a year because it will need to get formal consensus from many players, such as the SEC, American Association of Investors, Congress, the Big Four, American Associate of Realtors, the international equivalents of these, etc. If your accounting is a bit rusty, an Operating Lease is where you lease equipment or some asset for a shorter period than the actual (expected) life of the asset and then give the asset back while it still has some useful life in it. (Think leasing a car). Because an Operating Lease does not contain any of the provisions that would qualify it as a Capital Lease, the lease is not treated as a sale or purchase and hits the lessee's rental expense and the lessor's revenue. So it all stays on the P&L (assuming no prepayments are made). Capital Leases, on the other hand, hit lessee's and lessor's balance sheets because the asset is treated as a sale. (I'm ignoring interest and depreciation here to emphasize my point). Question: What will happen to real estate leases when Operating Leases go away and how will Oracle Financials address these changes? Before I attempt to address these questions, here's a real-life example to expound on some of the issues: Let's say a U.S. retailer leases a store in a mall for 15 years. Under U.S. GAAP, the lease is considered an operating or expense lease. Will that same lease be considered a capital lease under IFRS? Real estate leases are supposedly going to be capitalized under IFRS. If so, will everyone need to change all leases from operating to capital? Or, could we make some adjustments so we report the lease as an expense for operations reporting but capitalize it for SEC reporting? Would all aspects of the lease be capitalized, or would some line items still be expensed? For example, many retail store leases are defined to include (1) the agreed-to rent amount; (2) a negotiated increase in base rent, e.g., maybe a 5% increase in Year 5; (3) a sales rent component whereby the retailer pays a variable additional amount based on the sales generated in the prior month; (4) parking lot maintenance fees. Would the entire lease be capitalized, or would some portions still be expensed? To help answer these questions, I met up with our resident accounting expert and walking encyclopedia, Seamus Moran. Here's what he had to say: Oracle is aware of the potential changes specific to reporting/capitalization of real estate leases; i.e., we are aware that FASB and IASB have identified real estate leases as one of the areas for standards convergence. Oracle stays apprised of the on-going convergence through our domain expertise staff, our relationship with customers, our market awareness, and, of course, our relationships with the Big 4. This is part of our normal process with respect to regulatory compliance worldwide. At this time, Oracle expects that the standards convergence committee will make a recommendation about reporting standards for real estate leases in about a year. Following typical procedures, we also expect that the recommendation will be up for review for a year, and customers will then need to start reporting to the new standard about a year after that. So that means we would expect the first customer to report under the new standard in maybe 3 years. Typically, after the new standard is finalized and distributed, we find that our customers then begin to evaluate how they plan to meet the new standard. And through groups like the Customer Advisory Boards (CABs), our customers tell us what kind of product changes are needed in order to satisfy their new reporting requirements. Of course, Oracle is also working with the Big 4 and Accenture and other implementers in order to ascertain that these recommended changes will indeed meet new reporting standards. So the best advice we can offer right now is, stay apprised of the standards convergence committee; know that Oracle is also staying abreast of developments; get involved with your CAB so your voice is heard; know that Oracle products continue to be GAAP compliant, and we will continue to maintain that as our standard. But exactly what is that "standard"--we need to wait on the standards convergence committee. In a nut shell, operating leases will become either capital leases or month to month rentals, but it is still too early, too political and too uncertain to call out at this point.

  • Windows Azure Mobile Services Updates Keep Coming

    - by Clint Edmonson
    Some exciting new Windows Azure Mobile Services features were delivered to production this week. The highlights include: iPhone and iPad connectivity support via a new iOS SDK Integrated Authentication so developers can configure user authentication via Microsoft Account, Facebook, Twitter, and Google. New server-side Mobile Service script modules Access to Structured Storage, Windows Azure Blob, Table, Queues, and ServiceBus Email services through partnership with SendGrid SMS & voice services through partnership with Twilio Mobile Services hosting expanded to west coast US The iOS SDK I’m excited to share that we've announced the release of an under-development iOS client SDK for Windows Azure Mobile Services. The iOS SDK joins the Windows 8 SDK launched with Windows Azure Mobile Services as well as client SDKs released by Xamarin for MonoTouch and MonoDroid.  The native iOS SDK is for developers programming in Objective-C on the iPhone and iPad platforms. The SDK gives developers the same level of access to data storage using dynamic schematization that is available for Windows 8. Also, iOS applications can use the same authentication options available in Mobile Services. While full iOS support is still in development, the libraries are currently available on GitHub. There’s a great getting started tutorial to walk you through building a simple iOS “Todo List” app that stores data in Windows Azure.  These additional tutorials explore how to use the iOS client libraries to store data and authenticate users: Get Started with data in Mobile Services for iOS Get Started with authentication in Mobile Services for iOS What’s New in Authentication Available to both iOS and Windows 8 developers, Mobile Services has expanded its authentication options.  Developers can now use Microsoft, Facebook, Twitter, and Google authentication. Similar to using Microsoft accounts for authentication, developers must sign up and through Facebook, Twitter, or Google's developer portal in order to authenticate through them.  These tutorials walk through how to register your Mobile Service with an identity provider: How to register your app with Microsoft Account How to register your app with Facebook How to register your app with Twitter How to register your app with Google And these tutorials walk through authenticating against Mobile Services: Get started with authentication in Mobile Services for Windows Store (C#) Get started with authentication in Mobile Services for Windows Store (JavaScript) Get started with authentication in Mobile Services for iOS What’s New in Mobile Service Scripts Some great new functionality is now available in the Mobile Service script layer.  These server side scripts are triggered off of any CRUD operation on a Mobile Service's table and can already handle doing data and query validation, filtering, web requests and more.  Today, the Azure SDK module is now available to these scripts giving them access to blob storage, service bus, table storage.  Check out the new tutorials on the Windows Azure Node.js developer center to learn more about working with Blob, Tables, Queues and Service Bus using the azure module. In addition, SendGrid and Twilio are now available via modules that can be called from the scripts as well.  This gives developers the ability to send emails (SendGrid) or SMS text messages (Twilio) whenever a script is fired.  Windows Azure customers receive a special offer of 25,000 free emails per month from SendGrid and 1000 free text messages from Twilio. Expanded Data Center Availability In addition to Mobile Services being available in our US East data center, they can now be spun up in US West. The above features are all now live in production and are available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. The Windows Azure Mobile Developer Center has been updated with new tutorials that cover these new features in detail. And don’t forget - Windows Azure Mobile Services are still free for your first ten applications running on shared compute instances. Stay tuned to my twitter feed for Windows Azure announcements, updates, and links: @clinted

  • Extending QuickBooks Reporting with the QuickBooks ADO.NET Data Provider

    - by dataintegration
    The ADO.NET Provider for QuickBooks comes with several reports you may request from QuickBooks by default. However, there are many more that are not readily available. The ADO.NET Provider for QuickBooks makes it easy for you to create new reports and customize existing ones. In this article, we will illustrate how to create your own report and retrieve it from the Server Explorer in Visual Studio. For this example we will show how to create an Item Profitability Report. Creating the report script file Step 1: Download the sample reports available here. Extract them to a folder of your choice. Step 2: Make a copy of the ReportGeneralSummary.rsd file and rename it to ItemProfitability.rsd. Then open the file in any text editor. Step 3: Open the installation directory of the ADO.NET Provider for QuickBooks. Under the \db\ folder, locate the ReportJob.rsb file. Open this file in another text editor. Note: Although we are using ReportJob.rsb for this example, other reports may be contained in other Report*.rsb files. We recommend consulting the included help file and first locating the Report stored procedure and ReportType you are looking for. Otherwise, you may open each Report*.rsb file and look under the "reporttype" input for the report you are attempting to create. Step 4: First, let's rename the title of ItemProfitability.rsd. Near the top of the file you will see a title and description. Change the title to match the name of the file. Change the description to anything you like. For example: <rsb:info title="ItemProfitability" description="Executes my custom report."> Just below the Title, there are a number of columns. The Id represents the row number. The RowType represents the type of data returned by QuickBooks. The ColumnValue* columns represent all of the column data returned by QuickBooks. In some instances, we may need to add additional ColumnValue columns. Step 5: To add additional ColumnValue columns, simply copy the last column, paste it directly below, and continue increasing the numerical value at end of the attribute name. For example: <attr name="ColumnValue9" xs:type="string" readonly="true" required="false" desc="Represents a column of data."/> <attr name="ColumnValue10" xs:type="string" readonly="true" required="false" desc="Represents a column of data."/> <attr name="ColumnValue11" xs:type="string" readonly="true" required="false" desc="Represents a column of data."/> <attr name="ColumnValue12" xs:type="string" readonly="true" required="false" desc="Represents a column of data."/> ... Caution: Do not rename the ColumnValue* definitions themselves. They are generalized so that we can understand each type of report returned by QuickBooks. Renaming them to something other than ColumnValue* will cause your columns to return with null values. Step 6: Now let's update the available inputs for the table. From the ReportJob.rsb file, copy all of the input elements into ItemProfitability under the "Psuedo-Column definitions" comment. You will be replacing the existing input elements in ItemProfitability with inputs from ReportJob. When you are done, it should look like this: <!-- Psuedo-Column definitions --> <input name="reporttype" description="The type of the report." value="ITEMESTIMATESVSACTUALS,ITEMPROFITABILITY,JOBESTIMATESVSACTUALSDETAIL,JOBESTIMATESVSACTUALSSUMMARY,JOBPROFITABILITYDETAIL,JOBPROFITABILITYSUMMARY," default="ITEMESTIMATESVSACTUALS" /> <input name="reportperiod" description="Report date range in the format (fromdate:todate), and either value may be omitted for an open ended range (e.g. 2009-12-25:). Supported date format: yyyy-MM-dd." /> <input name="reportdaterangemacro" description="Use a predefined date range." value="ALL,TODAY,THISWEEK,THISWEEKTODATE,THISMONTH,THISMONTHTODATE,THISQUARTER,THISQUARTERTODATE,THISYEAR,THISYEARTODATE,YESTERDAY,LASTWEEK,LASTWEEKTODATE,LASTMONTH,LASTMONTHTODATE,LASTQUARTER,LASTQUARTERTODATE,LASTYEAR,LASTYEARTODATE,NEXTWEEK,NEXTFOURWEEKS,NEXTMONTH,NEXTQUARTER,NEXTYEAR," default="ALL" /> ... Step 7: Now let's update the operationname attribute. This needs to match the same operationname used by ReportJob. After you have copied the correct value from ReportJob.rsb, the operationname in ItemProfitability should look like so: <rsb:set attr="operationname" value="qbReportJob"/> Step 8: There is one more thing we can do to make this a true Item Profitability report. We can remove the reporttype input and hardcode the value. To do this, copy and paste the rsb:set used for operationname. Then rename the attr and value to match the name and value you want to use. For example: <rsb:set attr="operationname" value="qbReportJob"/> <rsb:set attr="reporttype" value="ITEMPROFITABILITY"/> After this you can remove the input for reporttype. Now that you have your own report file, we can move on to displaying the report in the Visual Studio server explorer. Accessing the report through the Data Provider Step 1: Open Visual Studio. In the Server Explorer, configure a new connection with the QuickBooks Data Provider. Step 2: For the Location connection string property, enter the directory where the new report has been saved to. Step 3: The new report should appear as a new view in the Server Explorer. Let's retrieve data from it. Step 4: You can specify any inputs in the WHERE clause. New Report Example Script To help you get started using this new QuickBooks Data Provider report, you will need to download the QuickBooks ADO.NET Data Provider and the fully functional sample script.

  • DTrace for Oracle Linux news: new beta release and conference appearances

    - by Lenz Grimmer
    A new set of RPM packages of our port of DTrace for Linux has just been published on the Unbreakable Linux Network. This is another beta release of our ongoing development effort to bring the DTrace framework to Linux. This release includes the following changes: The packages are now based on the final public release of the Unbreakable Enterprise Kernel Release 2 (2.6.39). The previous beta drop was based on a development version of the 2.6.39 kernel; there is no new functionality specific to DTrace in this release. The primary goal was to get the code base in sync with the released kernel version. Based on the feedback we received from some users in how their applications interact with dtrace, libdtrace is now a shared library. However, the API/ABI is not fully stabilized yet and may be subject to change. As a result of the ongoing QA testing, some test cases were reorganized into their own subdirectories, which allows running the test suite in a more fine-grained manner. As reminder, we have a dedicated Forum for DTrace on Linux, to discuss your experiences with this release. This week, the Linux DTrace team also attendeded the second dtrace.conf in San Francisco, to talk about their work. The sessions were streamed live and recordings are also available. You can watch Oracle's Kris Van Hees' talk below: Video streaming by Ustream We would like to thank the dtrace.conf organizers for the speaking opportunity and for organizing this event! This Wednesday (April 4th), Kris and Elena Zannoni also spoke on this topic at the Linux Foundation Collaboration Summit 2012 in San Francisco, CA. The slides are now available for download (PDF).

  • BizTalk 2009 - The Community ODBC Adapter: Installation

    - by Stuart Brierley
    I have previsouly detailed the installation of MySQL, the configuration of MySQL and the installation of the ODBC Data Connector for MySQL.  The reason I needed to install and configure these servers was to provide a test environment for a BizTalk Server 2009 solution I am working on where BizTalk will be querying and populating a MySQL database. To do this I then needed to install and add the Community ODBC adapter from Two Connect: "The Community BizTalk Adapter for ODBC is based on the code that was first made available on GotDotNet a few years ago. TwoConnect has refreshed this code, added an installer, and tested it against the latest BizTalk editions. We are releasing the updates back to the BizTalk developer, user and partner community as part of our ongoing community intitiatives. This is the second adapter package that TwoConnect makes available to the community after the very succesful release of the BizTalk WSE 3 adapter a couple of years ago. This adapter is useful in all ODBC based integration scenarios. The following are the new features added and fixes made to the old code base on GotDotNet." Detailed below are the installation instructions for this adapter.  Downloading and running the installer will load up the splash screen. Next you need to select the installation location for the adapter. You then need to confirm the installation following which you will be shown the installation progress. Assuming all has gone well you should see the installation complete screen. Once the installation has completed successfully you will then need to add the adapter to your BizTalk Server.  To do this open the BizTalk Administration console, expand the Platform Settings and right click on Adapters then select New\Adapter. You should then be able to select the ODBC adapter and choose the display name for the adapter. This adapter will then be shown in the BizTalk Administration console. Next I will be looking at using the ODBC Adapter when: Generating schemas Creating a receive port Creating a send port

  • Whole Lotta Virtualization Goin' On

    - by rickramsey
    Lately we've published a lot of content about virtualization. Here's a sampling. Podcat: Technology Preview of Transcendent Memory Turns out that in a virtual environment, RAM is the bottleneck. Not because it's slow, it's not, but because each CPU still had to use its own RAM. Which gets expensive. In this podcast, Dan Magenheimer describes how Oracle and the open source community taught the guest kernel in Oracle Linux to share its memory with other CPU's. Transcendent memory will wind up saving large data centers a lot of money. Find out how.

  • Announcing Release of Oracle Solaris Cluster 4.1!

    - by user9159196
    Oct 26, 2012We are very happy to announce the release of  Oracle Solaris Cluster 4.1, providing High Availability (HA) and  Disaster Recovery (DR) capabilities for Oracle Solaris 11.1.  This is yet another proof of Oracle's continued investment in Oracle Solaris technologies such as Oracle Solaris Cluster. For this new release we have improved the Solaris Cluster integration within the Oracle environment. For example  we've created new agents such as PeopleSoft JobScheduler or added the support of the Oracle ZFS Storage Appliance replication in the Geo Edition module (to facilitate disaster recovery in multi-site configuration equipped with those types of storage.) We have also extended the Oracle Solaris Zone Cluster feature with support of Oracle Solaris 10 zone clusters and exclusive-IP to facilitate deployment of virtualized or cloud architecture.And there are many more new features to discover in this release. Stay tuned for more specific articles. In the mean time check out the What's new document or even better, download the latest version from  here.Also, join the Oracle Solaris 11 Online Event on November 7 where an entire session will be devoted to discussing Oracle Solaris Cluster 4.1. Our Oracle Solaris Cluster engineers will be on hand to respond to your questions. We look forward to your feedback and inputs! -Nancy Chow and Eve Kleinknecht

  • Oracle Releases New Mainframe Re-Hosting in Oracle Tuxedo 11g

    - by Jason Williamson
    I'm excited to say that we've released our next generation of Re-hosting in 11g. In fact I'm doing some hands-on labs now for our Systems Integrators in Italy in a couple of weeks and targeting Latin America next month. If you are an SI, or Rehosting firm and are looking to become an Oracle Partner or get a better understanding of Tuxedo and how to use the workbench for rehosting...drop me a line. Oracle Tuxedo Application Runtime for CICS and Batch 11g provides a CICS API emulation and Batch environment that exploits the full range of Oracle Tuxedo's capabilities. Re-hosted applications run in a multi-node, grid environment with centralized production control. Also, enterprise integration of CICS application services benefits from an open and SOA-enabled framework. Key features include: CICS Application Runtime: Can run IBM CICS applications unchanged in an application grid, which enables the distribution of large workloads across multiple processors and nodes. This simplifies CICS administration and can scale to over 100,000 users and over 50,000 transactions per second. 3270 Terminal Server: Protects business users from change through support for tn3270 terminal emulation. Distributed CICS Resource Management: Simplifies deployment and administration by allowing customers to run CICS regions in a distributed configuration. Batch Application Runtime: Provides robust IBM JES-like job management that enables local or remote job submissions. In addition, distributed batch initiators can enable parallelization of jobs and support fail-over, shortening the batch window and helping to meet stringent SLAs. Batch Execution Environment: Helps to run IBM batch unchanged and also supports JCL functionality and all common batch utilities. Oracle Tuxedo Application Rehosting Workbench 11g provides a set of automated migration tools integrated around a central repository. The tools provide high precision which results in very low error rates and the ability to handle large applications. This enables less expensive, low-risk migration projects. Key capabilities include: Workbench Repository and Cataloguer: Ensures integrity of the migrated application assets through full dependency checking. The Cataloguer generates and maintains all relevant meta-data on source and target components. File Migrator: Supports reliable migration of datasets and flat files to an ISAM or Oracle Database 11g. This is done through the automated migration utilities for data unloading, reloading and validation. It also generates logical access functions to shield developers from data repository changes. DB2 Migrator: Similarly, this tool automates the migration of DB2 schema and data to Oracle Database 11g. COBOL Migrator: Supports migration of IBM mainframe COBOL assets (OLTP and Batch) to open systems. Adapts programs for compiler dialects and data access variations. JCL Migrator: Supports migration of IBM JCL jobs to a Tuxedo ART environment, maintaining the flow and characteristics of batch jobs.

  • Who broke the build?

    - by Martin Hinshelwood
    I recently sent round a list of broken builds at SSW and asked for them to be fixed or deleted if they are not being used. My colleague Peter came back with a couple of questions which I love as it tells me that at least one person reads my email I think first we need to answer a couple of other questions related to builds in general.   Why do we want the build to pass? Any developer can pick up a project and build it Standards can be enforced Constant quality is maintained Problems in code are identified early What could a failed build signify? Developers have not built and tested their code properly before checking in. Something added depends on a local resource that is not under version control or does not exist on the target computer. Developers are not writing tests to cover common problems. There are not enough tests to cover problems. Now we know why, lets answer Peters questions: Where is this list? (can we see it somehow) You can normally only see the builds listed for each project. But, you have a little application called “Build Notifications” on your computer. It is installed when you install Visual Studio 2010. Figure: Staring the build notification application on Windows 7. Once you have it open (it may disappear into your system tray) you should click “Options” and select all the projects you are involved in. This application only lists projects that have builds, so don’t worry if it is not listed. This just means you are about to setup a build, right? I just selected ALL projects that have builds. Figure: All builds are listed here In addition to seeing the list you will also get toast notification of build failure’s. How can we get more info on what broke the build? (who is interesting too, to point the finger but more important is what) The only thing worse than breaking the build, is continuing to develop on a broken build! Figure: I have highlighted the users who either are bad for braking the build, or very bad for not fixing it. To find out what is wrong with a build you need to open the build definition. You can open a web version by double clicking the build in the image above, or you can open it from “Team Explorer”. Just connect to your project and open out the “Builds” tree. Then Open the build by double clicking on it. Figure: Opening a build is easy, but double click it and then open a build run from the list. Figure: Good example, the build and tests have passed Figure: Bad example, there are 133 errors preventing POK from being built on the build server. For identifying failures see: Solution: Getting Silverlight to build on Team Build 2010 RC Solution: Testing Web Services with MSTest on Team Build Finding the problem on a partially succeeded build So, Peter asked about blame, let’s have a look and see: Figure: The build has been broken for so long I have no idea when it was broken, but everyone on this list is to blame (I am there too) The rest of the history is lost in the sands of time, there is no way to tell when the build was originally broken, or by whom, or even if it ever worked in the first place. Build should be protected by the team that uses them and the only way to do that is to have them own them. It is fine for me to go in and setup a build, but the ownership for a build should always reside with the person who broke it last. Conclusion This is an example of a pointless build. Lets be honest, if you have a system like TFS in place and builds are constantly left broken, or not added to projects then your developers don’t yet understand the value. I have found that adding a Gated Check-in helps instil that understanding of value. If you prevent them from checking in without passing that basic quality gate of “your code builds on another computer” then it makes them look more closely at why they can’t check-in. I have had builds fail because one developer had a “d” drive, but the build server did not. That is what they are there to catch.   If you want to know what builds to create and why I wrote a post on “Do you know the minimum builds to create on any branch?”   Technorati Tags: TFS2010,Gated Check-in,Builds,Build Failure,Broken Build

  • ODI - Creating a Repository in a 12c Pluggable Database

    - by David Allan
    To install ODI 11g into an Oracle 12c pluggable database, one way is to connect using a TNS string to the pluggable database service that is executing. For example when I installed my master repository, I used a JDBC URL such as; jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=mydbserver)(PORT=1522)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=PDBORA12.US.ORACLE.COM)))   I used the above approach rather than the host:port:sid which is a common mechanism many users use to quickly get up and going. Below you can see the repository creation wizard in action, I used the 11g release and simply installed the master and work repository into my pluggable database. Be wise with your repository IDs, I simply used the default, but you should be aware that these are key in larger deployments. The database in 12c has much more tighter control on users and resources, so just getting the user creating with sufficient resource on tablespaces etc in 12c was a little more work. Once you have the repositories up and running, then the fun starts using the 12c features. More to come.

    If you can’t get to a conference, let the conference come to you! There are a ton of free recorded conference presentations online… Microsoft TechEd Let’s start with the proverbial 800 pound gorilla. Recent TechEds have recorded the majority of presentations and made them available online the next day. Check out presentations from last month’s TechEd North America 2012 or last week’s TechEd Europe 2012. If you start at http://channel9.msdn.com/Events/TechEd, you can also drill down to presentations from prior years or from other regional TechEds (Australia, New Zealand, etc.) The top presentations from my “View Queue”: Damian Edwards: Microsoft ASP.NET and the Realtime Web (SignalR) Jennifer Smith: Design for Non-Designers Scott Hunter: ASP.NET Roadmap: One ASP.NET – Web Forms, MVC, Web API, and more Daniel Roth: Building HTTP Services with ASP.NET Web API Benjamin Day: Scrum Under a Waterfall NDC The Norwegian Developer Conference site has the most interesting presentations, in my opinion. You can find the videos from the June 2012 conference at that link. The 2011 and 2010 pages have a lot of presentations that are still relevant also. My View Queue Top 5: Shay Friedman: Roslyn... hmmmm... what? Hadi Hariri: Just ‘cause it’s JavaScript, doesn’t give you a license to write rubbish Paul Betts: Introduction to Rx Greg Young: How to get productive in a project in 24 hours Michael Feathers: Deep Design Lessons ØREDEV Travelling on from Norway to Sweden... I don’t know why, but the Scandinavians seem to have this conference thing figured out. ØREDEV happens each November, and you can find videos here and here. My View Queue Top 5: Marc Gravell: Web Performance Triage Robby Ingebretsen: Fonts, Form and Function: A Primer on Digital Typography Jon Skeet: Async 101 Chris Patterson: Hacking Developer Productivity Gary Short: .NET Collections Deep Dive aspConf - The Virtual ASP.NET Conference Formerly known as “mvcConf”, this one’s a little different. It’s a conference that takes place completely on the web. The next one’s happening July 17-18, and it’s not too late to register (It’s free!). Check out the recordings from February 2011 and July 2010.

  • New Experts Direct Contribution - Multiple Currency in Analytics

    - by Cheryl
    We do our best to anticipate what you need to know when we design and write our courses for CRM On Demand. But we know that we cannot hit on every situation or implementation scenario that you might encounter. That's why I love our Experts Direct program - this is where we encourage our wide network of CRM On Demand experts to contribute knowledge that they have gained from working directly with companies on their specific challenges or questions. (See Direct From Our Experts!) The latest Experts Direct contribution comes from Leon Dolman, who works with CRM On Demand customers every day. Leon addresses what you should expect to see in your reports and in the application when your company's users enter opportunity revenue information in more than one currency. He works through a scenario to show how currency settings can affect the data that you see in your reports. For example, do you know what will you see in your Opportunity reports if you have two different currencies represented, besides your company's default currency, but your company administrator has only set exchange rates for one of them? Leon knows...and now he has shared that knowledge - and more - with the rest of us. Go to the Multiple Currency in Analytics item in the Training and Support Center to read more - and while you're there, take a look at the other Experts Direct content to tap into that expert knowledge that we're collecting for you. Just click the Browse More Topics link in the Experts Direct box on the home page to see the full list. And let us know if there are other topics that you'd like to see our experts address.

  • Troubleshooting Microsoft Message Queuing Issues on Microsoft Lync Server 2010

    - by John Breakwell
    This blog post sounds specific but most of the troubleshooting tips can be applied to other scenarios: Troubleshooting Microsoft Message Queuing Issues on Microsoft Lync Server 2010 Microsoft Message Queuing (MSMQ) plays an important role in the Microsoft Lync Server 2010 Monitoring/Archiving server infrastructure: in a distributed network environment, MSMQ is used to transmit data from agents located on other servers (such as Front End Servers) to Monitoring/Archiving servers. The purpose of this article is to help you discover the root cause of any MSMQ problems that you might encounter, and to provide suggested ways to fix those problems. Microsoft Lync Server is the new name for Microsoft Office Communications Server. It’s good to see a major product make use of MSMQ – there aren’t many in the public eye (Symantec’s Enterprise Vault comes to mind).

  • Developing an Implementation Plan with Iterations by Russ Pitts

    - by user535886
    Developing an Implementation Plan with Iterations by Russ Pitts  Ok, so you have come to grips with understanding that applying the iterative concept, as defined by OUM is simply breaking up the project effort you have estimated for each phase into one or more six week calendar duration blocks of work. Idea being the business user(s) or key recipient(s) of work product(s) being developed never go longer than six weeks without having some sort of review or prototyping of the work results for an iteration…”think-a-little”, “do-a-little”, and “show-a-little” in a six week or less timeframe…ideally the business user(s) or key recipients(s) are involved throughout. You also understand the OUM concept that you only plan for that which you have knowledge of. The concept further defined, a project plan initially is developed at a high-level, and becomes more detailed as project knowledge grows. Agreeing to this concept means you also have to admit to the fallacy that one can plan with precision beyond six weeks into a project…Anything beyond six weeks is a best guess in most cases when dealing with software implementation projects. Project planning, as defined by OUM begins with the Implementation Plan view, which is a very high-level perspective of the effort estimated for each of the five OUM phases, as well as the number of iterations within each phase. You might wonder how can you predict the number of iterations for each phase at this early point in the project. Remember project planning is not an exact science, and initially is high-level and abstract in nature, and then becomes more detailed and precise as the project proceeds. So where do you start in defining iterations for each phase for a project? The following are three easy steps to initially define the number of iterations for each phase: Step 1 => Start with identifying the known factors… …Prior to starting a project you should know: · The agreed upon time-period for an iteration (e.g 6 weeks, or 4 weeks, or…) within a phase (recommend keeping iteration time-period consistent within a phase, if not for the entire project) · The number of resources available for the project · The number of total number of man-day (effort) you have estimated for each of the five OUM phases of the project · The number of work days for a week Step 2 => Calculate the man-days of effort required for an iteration within a phase… Lets assume for the sake of this example there are 10 project resources, and you have estimated 2,536 man-days of work effort which will need to occur for the elaboration phase of the project. Let’s also assume a week for this project is defined as 5 business days, and that each iteration in the elaboration phase will last a calendar duration of 6 weeks. A simple calculation is performed to calculate the daily burn rate for a single iteration, which produces a result of… ((Number of resources * days per week) * duration of iteration) = Number of days required per iteration ((10 resources * 5 days/week) * 6 weeks) = 300 man days of effort required per iteration Step 3 => Calculate the number of iterations that can occur within a phase Next calculate the number of iterations that can occur for the amount of man-days of effort estimated for the phase being considered… (number of man-days of effort estimated / number of man-days required per iteration) = # of iterations for phase (2,536 man-days of estimated effort for phase / 300 man days of effort required per iteration) = 8.45 iterations, which should be rounded to a whole number such as 9 iterations* *Note - It is important to note this is an approximate calculation, not an exact science. This particular example is a simple one, which assumes all resources are utilized throughout the phase, including tech resources, etc. (rounding down or up to a whole number based on project factor considerations). It is also best in many cases to round up to higher number, as this provides some calendar scheduling contingency.

  • C#/.NET Little Wonders: Using &lsquo;default&rsquo; to Get Default Values

    - by James Michael Hare
    Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. Today’s little wonder is another of those small items that can help a lot in certain situations, especially when writing generics.  In particular, it is useful in determining what the default value of a given type would be. The Problem: what’s the default value for a generic type? There comes a time when you’re writing generic code where you may want to set an item of a given generic type.  Seems simple enough, right?  We’ll let’s see! Let’s say we want to query a Dictionary<TKey, TValue> for a given key and get back the value, but if the key doesn’t exist, we’d like a default value instead of throwing an exception. So, for example, we might have a the following dictionary defined: 1: var lookup = new Dictionary<int, string> 2: { 3: { 1, "Apple" }, 4: { 2, "Orange" }, 5: { 3, "Banana" }, 6: { 4, "Pear" }, 7: { 9, "Peach" } 8: }; And using those definitions, perhaps we want to do something like this: 1: // assume a default 2: string value = "Unknown"; 3:  4: // if the item exists in dictionary, get its value 5: if (lookup.ContainsKey(5)) 6: { 7: value = lookup[5]; 8: } But that’s inefficient, because then we’re double-hashing (once for ContainsKey() and once for the indexer).  Well, to avoid the double-hashing, we could use TryGetValue() instead: 1: string value; 2:  3: // if key exists, value will be put in value, if not default it 4: if (!lookup.TryGetValue(5, out value)) 5: { 6: value = "Unknown"; 7: } But the “flow” of using of TryGetValue() can get clunky at times when you just want to assign either the value or a default to a variable.  Essentially it’s 3-ish lines (depending on formatting) for 1 assignment.  So perhaps instead we’d like to write an extension method to support a cleaner interface that will return a default if the item isn’t found: 1: public static class DictionaryExtensions 2: { 3: public static TValue GetValueOrDefault<TKey, TValue>(this Dictionary<TKey, TValue> dict, 4: TKey key, TValue defaultIfNotFound) 5: { 6: TValue value; 7:  8: // value will be the result or the default for TValue 9: if (!dict.TryGetValue(key, out value)) 10: { 11: value = defaultIfNotFound; 12: } 13:  14: return value; 15: } 16: } 17:  So this creates an extension method on Dictionary<TKey, TValue> that will attempt to get a value using the given key, and will return the defaultIfNotFound as a stand-in if the key does not exist. This code compiles, fine, but what if we would like to go one step further and allow them to specify a default if not found, or accept the default for the type?  Obviously, we could overload the method to take the default or not, but that would be duplicated code and a bit heavy for just specifying a default.  It seems reasonable that we could set the not found value to be either the default for the type, or the specified value. So what if we defaulted the type to null? 1: public static TValue GetValueOrDefault<TKey, TValue>(this Dictionary<TKey, TValue> dict, 2: TKey key, TValue defaultIfNotFound = null) // ... No, this won’t work, because only reference types (and Nullable<T> wrapped types due to syntactical sugar) can be assigned to null.  So what about a calling parameterless constructor? 1: public static TValue GetValueOrDefault<TKey, TValue>(this Dictionary<TKey, TValue> dict, 2: TKey key, TValue defaultIfNotFound = new TValue()) // ... No, this won’t work either for several reasons.  First, we’d expect a reference type to return null, not an “empty” instance.  Secondly, not all reference types have a parameter-less constructor (string for example does not).  And finally, a constructor cannot be determined at compile-time, while default values can. The Solution: default(T) – returns the default value for type T Many of us know the default keyword for its uses in switch statements as the default case.  But it has another use as well: it can return us the default value for a given type.  And since it generates the same defaults that default field initialization uses, it can be determined at compile-time as well. For example: 1: var x = default(int); // x is 0 2:  3: var y = default(bool); // y is false 4:  5: var z = default(string); // z is null 6:  7: var t = default(TimeSpan); // t is a TimeSpan with Ticks == 0 8:  9: var n = default(int?); // n is a Nullable<int> with HasValue == false Notice that for numeric types the default is 0, and for reference types the default is null.  In addition, for struct types, the value is a default-constructed struct – which simply means a struct where every field has their default value (hence 0 Ticks for TimeSpan, etc.). So using this, we could modify our code to this: 1: public static class DictionaryExtensions 2: { 3: public static TValue GetValueOrDefault<TKey, TValue>(this Dictionary<TKey, TValue> dict, 4: TKey key, TValue defaultIfNotFound = default(TValue)) 5: { 6: TValue value; 7:  8: // value will be the result or the default for TValue 9: if (!dict.TryGetValue(key, out value)) 10: { 11: value = defaultIfNotFound; 12: } 13:  14: return value; 15: } 16: } Now, if defaultIfNotFound is unspecified, it will use default(TValue) which will be the default value for whatever value type the dictionary holds.  So let’s consider how we could use this: 1: lookup.GetValueOrDefault(1); // returns “Apple” 2:  3: lookup.GetValueOrDefault(5); // returns null 4:  5: lookup.GetValueOrDefault(5, “Unknown”); // returns “Unknown” 6:  Again, do not confuse a parameter-less constructor with the default value for a type.  Remember that the default value for any type is the compile-time default for any instance of that type (0 for numeric, false for bool, null for reference types, and struct will all default fields for struct).  Consider the difference: 1: // both zero 2: int i1 = default(int); 3: int i2 = new int(); 4:  5: // both “zeroed” structs 6: var dt1 = default(DateTime); 7: var dt2 = new DateTime(); 8:  9: // sb1 is null, sb2 is an “empty” string builder 10: var sb1 = default(StringBuilder()); 11: var sb2 = new StringBuilder(); So in the above code, notice that the value types all resolve the same whether using default or parameter-less construction.  This is because a value type is never null (even Nullable<T> wrapped types are never “null” in a reference sense), they will just by default contain fields with all default values. However, for reference types, the default is null and not a constructed instance.  Also it should be noted that not all classes have parameter-less constructors (string, for instance, doesn’t have one – and doesn’t need one). Summary Whenever you need to get the default value for a type, especially a generic type, consider using the default keyword.  This handy word will give you the default value for the given type at compile-time, which can then be used for initialization, optional parameters, etc. Technorati Tags: C#,CSharp,.NET,Little Wonders,default
