• Using multiple diagrams per model in Entity Framework 5.0

  - by nikolaosk

  I have downloaded .Net framework 4.5 and Visual Studio 2012 since it was released to MSDN subscribers on the 15th of August.For people that do not know about that yet please have a look at Jason Zander's excellent blog post .Since then I have been investigating the many new features that have been introduced in this release.In this post I will be looking into theIn order to follow along this post you must have Visual Studio 2012 and .Net Framework 4.5 installed in your machine.Download and install VS 20120 using this link.My machine runs on Windows 8 and Visual Studio 2012 works just fine. I have also installed in my machine SQL Server 2012 developer edition. I have also downloaded and installed AdventureWorksLT2012 database.You can download this database from the codeplex website.   Before I start showcasing the demo I want to say that I strongly believe that Entity Framework is maturing really fast and now at version 5.0 can be used as your data access layer in all your .Net projects.I have posted extensively about Entity Framework in my blog.Please find all the EF related posts here. In this demo I will show you how to split an entity model into multiple diagrams using the new enhanced EF designer. We will not build an application in this demo.Sometimes our model can become too large to edit or view.In earlier versions we could only have one diagram per EDMX file.In EF 5.0 we can split the model into more diagrams.1) Launch VS 2012. Express edition will work fine.2) Create a New Project. From the available templates choose a Web Forms application  3) Add a new item in your project, an ADO.Net Entity Data Model. I have named it AdventureWorksLT.edmx.Then we will create the model from the database and click Next.Create a new connection by specifying the SQL Server instance and the database name and click OK.Then click Next in the wizard.In the next screen of the wizard select all the tables from the database and hit Finish.4) It will take a while for our .edmx diagram to be created. When I select an Entity (e.g Customer) from my diagram and right click on it,a new option appears "Move to new Diagram".Make sure you have the Model Browser window open.Have a look at the picture below 5) When we do that a new diagram is created and our new Entity is moved there.Have a look at the picture below  6) We can also right-click and include the related entities. Have a look at the picture below. 7) When we do that the related entities are copied to the new diagram.Have a look at the picture below  8) Now we can cut (CTRL+X) the entities from Diagram2 and paste them back to Diagram1.9) Finally another great enhancement of the EF 5.0 designer is that you can change colors in the various entities that make up the model.Select the entities you want to change color, then in the Properties window choose the color of your choice. Have a look at the picture below. To recap we have demonstrated how to split your entity model in multiple diagrams which comes handy in EF models that have a large number of entities in them Hope it helps!!!!

• What are some good realistic programming related movies (docu-dramas, documentaries, accurate fiction, etc)?

  - by EpsilonVector

  A while ago I asked this question and the result was this. Following the response I got in the meta question I'm re-asking the question with new guidelines to focus it on the direction I wanted it to have originally. ================================================================== The guidelines are as follows: by "programming related" I mean movies from which we can learn about stuff like the development process, or history of software/computers, or programming culture. In other words, they must be grounded in the industry. No tangential stuff. Good entries answer as many of the following criteria as possible: Teach you about the history of the industry, or the development process, or teach you about important industry related topics (software patents for example) Are based on real life events, companies, people, practices, and they are the main focus of the movie After watching them, you feel like you understand or know something about the programmers' world that you didn't before (or you can see how someone could have such a response). You can point to it and say "this faithfully represents the industry/programmer culture at some point in time". This might be something you would show laymen to explain to them what "your people" are like and what is it that you do. Examples for good entries include: Pirates of Silicon Valley- the story of how Microsoft and Apple started the industry. Revolution OS- The story of Linux's rise to fame, and a pretty good cover of the Free Software/Open Source world. Aardvark'd: 12 Weeks with Geeks- development process. Examples for bad entries: Movies who's sole relevance is that they can be appreciated by programmers. The point of this question is not to be "what are some good movies" with "for a programmer" appended to it. Just because the writers got a few computer jokes right in itself doesn't make it about the industry. Movies where there's a computer related element, but are not about the industry. For example, 24 (the TV series). It's a product of the information age but it isn't actually about it. Another example is movies where there's a really cool programmer character, but are overall about something completely different. Likewise, The Big Bang Theory is not about physics, even though they have a cool physicist as a character. Science fiction, even if it draws ideas from computers. For example, the Matrix trilogy. Movies that you can't point to them and say: this is a faithful representation of our world (at some point in time). If you can't do that then it doesn't mirror the industry. Keep it one entry per answer so that the voting could sort the entries out.

• Partial Submit vs. Auto Submit

  - by Frank Nimphius

  Partial Submit ADF Faces adds the concept of partial form submit to JavaServer Faces 1.2 and beyond. A partial submit actually is a form submit that does not require a page refresh and only updates components in the view that are referenced from the command component PartialTriggers property. Another option for refreshing a component in response to a partial submit is call AdfContext.getCurrentInstance.addPartialTarget(component_instance_handle_goes_here)in a managed bean. If a form contains required fields that the user left empty invoking the partial submit, then errors are shown for each of the field as the full form gets submitted. Autosubmit An input component that has its autosubmit property set to true also performs a partial submit of the form. However, this time it doesn't submit the entire form but only the component that triggers the submit plus components referenced it in their PartialTriggers property. For example, consider a form that has three input fields inpA, inpB and inpC with autosubmit=true set on inpA and required=true set on inpB and inpC. use case 1: Running the view, entering data into inpA and then tabbing out of the field will submit the content for inpA but not for inpB and inpC. Further more, none of the required field settings on inpB and inpC causes an error. use case 2: You change the configuration of inpC and set its PartialTriggers property to point to the ID of component inpA. When rerunning the sample, entering a value into inpA and tabbing out of the field will now submit the inpA and inpC fields and thus show an error for the missing required value on inpC. Internally, using autosubmit=true on an input component sets the event root to just this field, which good to have in case of dependent field validation or behavior. The event root can extended to include other components by using the Partial Triggers property on these components to point to the input field that has autosubmit=true defined. PartialSubmit vs. AutoSubmit Partial submit set on a command component submits the whole form and leaves it to the developer to decide which UI component is refreshed in response. Client side required field validation (as well as the server side equivalent) is not disabled by executed in this scenario. Setting immediate=true on the command item to skip validation doesn't help as it would also skip the model update. Auto submit is a functionality on the input components and also performs a partial form submit. However, in addition an event root is defined that narrows the scope for the submitted data and thus the components that are validated on the request.

• A Hot Topic - Profitability and Cost Management

  - by john.orourke(at)oracle.com

  Maybe it's due to the recent recession, or current economic recovery but a hot topic and area of focus for many organizations these days is profitability and cost management.  For most organizations, aggressive cost-cutting and cost management were critical to remaining profitable while top line revenue was flat or shrinking.  However, now we are seeing many organizations taking a more "surgical" approach to profitability and cost management, by accurately allocating revenue and costs to individual product lines, services, customer segments, locations, channels and other lines of business to understand which ones are truly profitable and which ones are not.  Based on these insights, managers can make more informed decisions about which products or services to invest in or retire, how to price their products or services for different customer segments, and where to focus their marketing and customer service resources. The most common industries where this product, service and customer-focused costing and profitability analysis is being adopted include financial services, consumer packaged goods, retail and manufacturing.  However we are seeing adoption of profitability and cost management applications in other industries and use cases.  Here are a few examples: Telecommunications Industry:  Network Costing and Management to identify the most cost effective and/or profitable network areas, to optimize existing resources, infrastructure and network capacity.  Regulatory Cost Accounting to perform more accurate allocations of revenue and costs across services and customer segments, improve ability to set billing rates for future periods, for various products and customer segments and more easily develop analysis needed for rate case proposals. Healthcare Insurance:  Visually, justifiable Medical Loss Ratio results, better knowledge of the cost to service healthcare plans and members, accurate understanding of member segment and plan profitability, improved marketing programs through better member segmentation. Public Sector:  Statutory / Regulatory Compliance:  A variety of statutory and regulatory documents state explicitly or implicitly that the use of government resources must be properly tracked and tied to performance goals.  Managerial costing methods implemented through Cost Management applications provide unparalleled visibility into costs and shared services usage throughout a Public Sector agency. Funding Support:  Regulations require public sector funding requests to be evaluated based upon the ability to achieve performance goals against the associated cost.   Improved visibility and understanding of costs of different programs/services means that organizations can demonstrably monitor performance and the associated resource costs improve the chances of having their funding requests granted. Profitability and Cost Management is one of the fastest-growing solution areas in Oracle's Enterprise Performance Management product line and we are seeing a growing number of customer successes across geographies and industries.  Listed below are just a few examples.  Here's a link to the replay from a recent webcast on this topic which featured Schroders Plc, a UK-based Financial Services company: http://www.oracle.com/go/?&Src=7011668&Act=168&pcode=WWMK10037859MPP043 Here's a link to a case study on Shenhua Guohua Power in China: http://www.oracle.com/us/corporate/customers/shenhua-snapshot-159574.pdf Here's a link to information on Oracle's web site about our profitability and cost management solutions: http://www.oracle.com/us/solutions/ent-performance-bi/performance-management/profitability-cost-mgmt/index.html

• Content Based Routing with BRE and ESB

  - by Christopher House

  I've been working with BizTalk 2009 and the ESB toolkit for the past couple of days.  This is actually my first exposure to ESB and so far I'm pleased with how easy it is to work with. Initially we had planned to use UDDI for storing endpoint information.  However after discussing this with my client, we opted to look at BRE instead of UDDI since we're already storing transforms in BRE.  Fortunately making the change to BRE from UDDI was quite simple.  This solution of course has the added advantage of not needing to go through the convoluted process of registering our endpoints in UDDI. The first thing to remember if you want to do content based routing with BRE and ESB is that the pipleines included in the ESB toolkit don't include disassembler components.  This means that you'll need to first create a custom recieve pipeline with the necessary disassembler for your message type as well as the ESB components, itinerary selector and dispather. Next you need to create a BRE policy.  The ESB.ContextInfo vocabulary contains vocabulary links for the various items in the ESB context dictionary.  In this vocabulary, you'll find an item called Context Message Type, use this as the left hand side of your condition.  Set the right hand side to your message type, something like http://your.message.namespace/#yourrootelement.  Now find the ESB.EndPointInfo vocabulary.  This contains links to all the properties related to endpoint information.  Use the various set operators in your rule's action to configure your endpoint. In the example above, I'm using the WCF-SQL adapter. Now that the hard work is out of the way, you just need to configure the resolver in your itinerary. Nothing complicated here.  Just select BRE as your resolver implementation and select your policy from the drop-down list.  Note that when you select a policy, the Version field will be automatically filled in with the version of your policy.  If you leave this as-is, the resolver will always use that policy version.  Alternatively, you can clear the version number and the resolver will use the highest deployed version.

• SQL installation scripts for WebCenter Content 11g

  - by KJH

  As part of the installation of WebCenter Content 11g (UCM or URM), one of the main functions is to run the Repository Creation Utility (RCU) to establish the database schema and tables.   This is pretty helpful because it runs all the scripts you need to have without having to manually set anything up in the database.   In UCM 10g and earlier, the installation  itself would establish the database tables if you wanted it to.  Otherwise, the SQL scripts were available to be run independently ahead of time.  For DBAs who wanted to understand what was being done to the database for the application, this was helpful for them.  But in 11g, that is all masked now in RCU.  You don't get to see the scripts at all as part of it's establishing the tables.  But if you comb through the directories for RCU, you can track them down.  They are in the  /rcuHome/rcu/integration/contentserver11/sql/ directories.  And to understand the order in which they are run, you can open up the /rcuHome/rcu/integration/contentserver11/contentserver11.xml file and see how they are run there.  The order in which they are run are: contentserverrole.sql contentserveruser.sql intradoc.sql workflow.sql formats.sql users.sql default.sql contentprocedures.sql  If you are installing WebCenter Records (URM), it will run some additional scripts between the formats.sql and users.sql : MetadataSet.sql UIEnhancements.sql RecordsManagement.sql RecordsManagement_default.sql ClassifiedEnhancements.sql ClassifiedEnhancements_default.sql In addition to the scripts being available within the RCU install directories, they are also available from within the Content Server UI.  If you go to Administration -> DataStoreDesign SQL Generation, this page can allow you to download these various SQL scripts.    From here, you can select your particular database type and which components to include.  Several components make changes dynamically to the database when they are enabled, so these scripts give you a way to inspect what is being run during that startup time.  Once selected, click Generate and you now can either view or download the scripts from the Actions menu. DISCLAIMER:  Installations are ONLY supported when done with the Repository Creation Utility.  These scripts are for reference only and not supported to be run manually.

• JDK bug migration milestone: JIRA now the system of record

  - by darcy

  I'm pleased to announce the OpenJDK bug database migration project has reached a significant milestone: the JDK has switched from the legacy Sun "bugtraq" system to a new internal JIRA instance as the system of record for our bug tracking. This completes the initial phase of the previously described plan of getting OpenJDK onto an externally visible and writable bug tracker. The identities contained in the current system include recognized OpenJDK contributors. The bug migration effort to date has been sizable in multiple dimensions. There are around 140,000 distinct issues imported into the JDK project of the JIRA instance, nearly 165,000 if backport issues to track multiple-release information are included. Separately, the Code Tools OpenJDK project has its own JIRA project populated with several thousands existing bugs. Once the OpenJDK JIRA instance is externalized, approved OpenJDK projects will be able to request the creation of a JIRA project for issue tracking. There are many differences in the schema used to model bugs between the legacy bug system and the schema for the new JIRA projects. We've favored simplifications to the existing system where possible and, after much discussion, we've settled on five main states for the OpenJDK JIRA projects: New Open In progress Resolved Closed The Open and In-progress states can have a substate Understanding field set to track whether the issues has its "Cause Known" or "Fix understood". In the closed state, a Verification field can indicate whether a fix has been verified, unverified, or if the fix has failed. At the moment, there will be very little externally visible difference between JIRA for OpenJDK and the legacy system it replaces. One difference is that bug numbers for newly filed issues in the JIRA JDK project will be 8000000 and above. If you are working with JDK Hg repositories, update any local copies of jcheck to the latest version which recognizes this expanded bug range. (The bug numbers of existing issues have been preserved on the import into JIRA). Relatively soon, we plan for the pages published on bugs.sun.com to be generated from information in JIRA rather than in the legacy system. When this occurs, there will be some differences in the page display and the terminology used will be revised to reflect JIRA usage, such as referring to the "component/subcomponent" of an issue rather than its "category". The exact timing of this transition will be announced when it is known. We don't currently have a firm timeline for externalization of the JIRA system. Updates will be provided as they become available. However, that is unlikely to happen before JavaOne next week!

• How can I set up Friendly URL to Nginx?

  - by MKK

  I'm trying to use dokuwiki with its Friendly URL on Nginx. The problem that I'm facing is, it doesn' show correct path to any link(even stylesheet, and images) on every page It looks that paths are missing wiki/ part. If I click on the image and show its destination, it shows this url http://foo-sample.com/lib/tpl/dokuwiki/images/logo.png But it has to be this below. http://foo-sample.com/wiki/lib/tpl/dokuwiki/images/logo.png and login URL is not working either. If I click on login link, it takes me to http://foo-sample.com/wiki/start?do=login&sectok=ff7d4a68936033ed398a8b82ac9 and it says 404 Not Found I took a look at this https://www.dokuwiki.org/rewrite#nginx and tried as much as possible. However it still doesn't work. Here's my conf files.

• Windows Phone 7 Development Updates &ndash; March 8th 2011

  - by Nikita Polyakov

  Here are the latest update from the Windows Phone 7 Developer Worlds that went live this month. Here are some of the latest numbers: Windows Phone Marketplace currently offers more than 9,000 quality apps and games and enjoys a base of over 32,000 registered developers, delivering an average of 100 new apps every day. There have been over 1 million downloads of the developers tools for Windows Phone 7. Trial version help you sell more Trials result in higher sales by the numbers: Users like trials  - paid apps with trial functionality are downloaded 70 times more than paid apps that don’t Nearly 1 out of 10 trial apps downloaded convert to a purchase and generate 10 times more revenue on average than paid apps that don’t include trial functionality. Trial downloads convert to paid downloads quickly. More than half of trial downloads that convert to a sale do so within the 1st 24 hours of trial download, and mostly within 2 hours of trial download. Microsoft Ad Control is gaining traction By the numbers - ad supported Windows Phone 7 apps are: Roughly ¼ of all registered U.S. WP7 developers have downloaded the free Ad SDK for Silverlight and XNA Of ad funded apps, over 95 percent use the free Microsoft Advertising Ad Control Monthly impressions from our Ad Exchange has continued to grow by double digits – impressions increased by 376 percent since January Ad Control, the first wave of “How Do I” videos are now available on MSDN: Create an Ad in a Windows Phone 7 XNA Game App Register Ad-Enabled Windows Phone 7 Apps Measure Ad Performance of Windows Phone 7 Apps Boarder International App submission for Free Apps through Yalla Apps As of today you can start submitting your free applications in developer markets that are currently not covered by Microsoft. To submit your Free application if you DO NOT belong to one of the Marketplace supported countries, go to: Yalla Apps Marketplace Policy Updates: Free App Marketplace Submission upped to 100 and other news Microsoft has been revisiting a few of our Marketplace policies based on feedback from developers to reduce friction and cost, word for word: 1. We have raised the limit on the number of certifications that can be performed for FREE apps at no cost to the registered developer from five to 100. This was a common request from developers which we are glad to implement after building alternate methods to ensure that users can find and download high quality apps. 2. We have converted policy 5.6 - related to the inclusion of contact information for support - from a mandatory to an optional policy. This is still a strongly recommended best practice, but we recognized and responded to developer feedback that this policy was creating excessive drag on the certification process for developers without commensurate user benefit for all apps. 3. We also understand the desire for clarification with regard to our policy on applications distributed under open source licenses.  The Marketplace Application Provider Agreement (APA) already permits applications under the BSD, MIT, Apache Software License 2.0 and Microsoft Public License.  We plan to update the APA shortly to clarify that we also permit applications under the Eclipse Public License, the Mozilla Public License and other, similar licenses and we continue to explore the possibility of accommodating additional OSS licenses. Enjoy and happy coding! Official Blog Post for reference.

• Pay in the future should make you think in the present

  - by BuckWoody

  Distributed Computing - and more importantly “-as-a-Service” models of computing have a different cost model. This is something that sounds obvious on the surface but it’s often forgotten during the design and coding phase of a project. In on-premises computing, we’re used to purchasing a server and all of the hardware infrastructure and software licenses needed not only for one project, but several. This is an up-front or “sunk” cost that we consume by running code the organization needs to perform its function. Using a direct connection over wires you’ve already paid for, we don’t often have to think about bandwidth, hits on the data store or the amount of compute we use - we just know more is better. In a pay-as-you-go model, however, each of these architecture decisions has a potential cost impact. The amount of data you store, the number of times you access it, and the amount you send back all come with a charge. The offset is that you don’t buy anything at all up-front, so that sunk cost is freed up. And financial professionals know that money now is worth more than money later. Saving that up-front cost allows you to invest it in other things. It’s not just that you’re using things that now cost money - it’s that the design itself in distributed computing has a cost impact. That can be a really good thing, such as when you dynamically add capacity for paying customers. If you can tie back the cost of a series of clicks to what a user will pay to do so, you can set a profit margin that is easy to track. Here’s a case in point: Assume you are using a large instance in Windows Azure to compute some data that you retrieve from a SQL Azure database. If you don’t monitor the path of the application, you may not know what you are really using. Since you’re paying by the size of the instance, it’s best to maximize it all the time. Recently I evaluated just this situation, and found that downsizing the instance and adding another one where needed, adding a caching function to the application, moving part of the data into Windows Azure tables not only increased the speed of the application, but reduced the cost and more closely tied the cost to the profit. The key is this: from the very outset - the design - make sure you include metrics to measure for the cost/performance (sometimes these are the same) for your application. Windows Azure opens up awesome new ways of doing things, so make sure you study distributed systems architecture before you try and force in the application design you have on premises into your new application structure.

• Finding a new programming language for web development?

  - by Xeoncross

  I'm wondering if there are any un-biased resources that give good, specific overviews of programming languages and their intended goals. I would like to learn a new language, but visiting the sites of each language isn't working. Each one talks about how great it is without much mention of it's weaknesses or specific goals. Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. Python is a programming language that lets you work more quickly and integrate your systems more effectively. Having been a PHP developer for years, Vic Cherubini sums up my plight well: I knew PHP well, had my own framework, and could work quickly to get something up and running. I programmed like this throughout the MVC revolution. I got better and better jobs (read: better paying, better title) as a PHP developer, but all along the way realizing that the code I wrote on my own time was great, and the code I worked with at work was horrible. Like, worse than horrible. Atrocious. OS Commerce level bad. Having side projects kept me sane, because the code I worked with at work made me miserable. This is why I'm retiring from PHP for my side projects and new programming ventures. I'm spent with PHP. Exhausted, if you will. I've reached a level where I think I'm at the top with it as a language and if I don't move on to a new language soon, I'll be done completely with programming and I do not want that. Languages I've looked at include JavaScript (for node.js), Ruby, Python, & Erlang. I've even thought about Scala or C++. The problem is figuring out which ones are built to handle my needs the best. So where can I go to skip the hype and get real information about the maturity of a platform, the size of the community, and the strengths & weaknesses of that language. If I know these then picking a language to continue my web development should be easy.

• Mouse Clicks, Reactive Extensions and StreamInsight Mashup

  I had an hour spare this afternoon so I wanted to have another play with Reactive Extensions in .Net and StreamInsight.  I also didn’t want to simply use a console window as a way of gathering events so I decided to use a windows form instead. The task I set myself was this. Whenever I click on my form I want to subscribe to the event and output its location to the console window and also the timestamp of the event.  In addition to this I want to know for every mouse click I do, how many mouse clicks have happened in the last 5 seconds. The second point here is really interesting.  I have often found this when working with people on problems.  It is how you ask the question that determines how you tackle the problem.  I will show 2 ways of possibly answering the second question depending on how the question was interpreted. As a side effect of this example I will show how time in StreamInsight can stand still.  This is an important concept and we can see it in the output later. Now to the code.  I will break it all down in this blogpost but you can download the solution and see it all together. I created a Console application and then instantiate a windows form.   frm = new Form(); Thread g = new Thread(CallUI); g.SetApartmentState(ApartmentState.STA); g.Start();   Call UI looks like this   static void CallUI() { System.Windows.Forms.Application.Run(frm); frm.Activate(); frm.BringToFront(); }   Now what we need to do is create an observable from the MouseClick event on the form.  For this we use the Reactive Extensions.   var lblevt = Observable.FromEvent<MouseEventArgs>(frm, "MouseClick").Timestamp();   As mentioned earlier I have two objectives in this example and to solve the first I am going to again use the Reactive extensions.  Let’s subscribe to the MouseClick event and output the location and timestamp to the console. lblevt.Subscribe(evt => { Console.WriteLine("Clicked: {0}, {1} ", evt.Value.EventArgs.Location,evt.Timestamp); }); That should take care of obective #1 but what about the second objective.  For that we need some temporal windowing and this means StreamInsight.  First we need to turn our Observable collection of MouseClick events into a PointStream Server s = Server.Create("Default"); Microsoft.ComplexEventProcessing.Application a = s.CreateApplication("MouseClicks"); var input = lblevt.ToPointStream( a, evt => PointEvent.CreateInsert( evt.Timestamp, new { loc = evt.Value.EventArgs.Location.ToString(), ts = evt.Timestamp.ToLocalTime().ToString() }), AdvanceTimeSettings.IncreasingStartTime);   Now that we have created out PointStream we need to do something with it and this is where we get to our second objective.  It is pretty clear that we want some kind of windowing but what? Here is one way of doing it.  It might not be what you wanted but again it is how the second objective is interpreted   var q = from i in input.TumblingWindow(TimeSpan.FromSeconds(5), HoppingWindowOutputPolicy.ClipToWindowEnd) select new { CountOfClicks = i.Count() };   The above code creates tumbling windows of 5 seconds and counts the number of events in the windows.  If there are no events in the window then no result is output.  Likewise until an event (MouseClick) is issued then we do not see anything in the output (that is not strictly true because it is the CTI strapped to our MouseClick events that flush the events through the StreamInsight engine not the events themselves).  This approach is centred around the windows and not the events.  Until the windows complete and a CTI is issued then no events are pushed through. An alternate way of answering our second question is below   var q = from i in input.AlterEventDuration(evt => TimeSpan.FromSeconds(5)).SnapshotWindow(SnapshotWindowOutputPolicy.Clip) select new { CountOfClicks = i.Count() };   In this code we extend the duration of each MouseClick to five seconds.  We then create  Snapshot Windows over those events.  Snapshot windows are discussed in detail here.  With this solution we are centred around the events.  It is the events that are driving the output.  Let’s have a look at the output from this solution as it may be a little confusing. First though let me show how we get the output from StreamInsight into the Console window. foreach (var x in q.ToPointEnumerable().Where(e => e.EventKind != EventKind.Cti)) { Console.WriteLine(x.Payload.CountOfClicks); }   Ok so now to the output.   The table at the top shows the output from our routine and the table at the bottom helps to explain the output.  One of the things that will help as well is, you will note that for our PointStream we set the issuing of CTIs to be IncreasingStartTime.  What this means is that the CTI is placed right at the start of the event so will not flush the event with which it was issued but will flush those prior to it.  In the bottom table the Blue fill is where we issued a click.  Yellow fill is the duration and boundaries of our events.  The numbers at the bottom indicate the count of events   Clicked 22:40:16                                 Clicked 23:40:18                                 1                                   Clicked 23:40:20                                 2                                   Clicked 23:40:22                                 3                                   2                                   Clicked 23:40:24                                 3                                   2                                   Clicked 23:40:32                                 3                                   2                                   1                                                                                                         secs 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32                                                                                                                                                                                                                         counts   1   2 3 2 3 2 3   2   1           What we can see here in the output is that the counts include all the end edges that have occurred between the mouse clicks.  If we look specifically at the mouse click at 22:40:32. then we see that 3 events are returned to us. These include the following End Edge count at 22:40:25 End Edge count at 22:40:27 End Edge count at 22:40:29 Another thing we notice is that until we actually issue a CTI at 22:40:32 then those last 3 snapshot window counts will never be reported. Hopefully this has helped to explain  a few concepts around StreamInsight and the IObservable() pattern.   You can download this solution from here and play.  You will need the Reactive Framework from here and StreamInsight 1.1

• Size doesn't matter

  - by ssoolsma

  Whenever I start a new project I *always* break up my code in different projects. Also known as n-tier solution. The scale of  the project doesn't matter, but make sure that each project is responsible for himself (or herself if you prefer). I make sure that i ....At least thought about how the project should work on the toilet or in a project team meeting.Have a solution directory and create my projects within. I like to name my project (and it's folders by the namespaces). For instance: When i'm creating a piece of (web)software called: ChuckNorris, i always include the software name in my projects. Start off with designing the DataAccess project. I name it: ChuckNorris.DataAccess which lets me easily identify the project incase the project scales alot.Build the classes which represent the database structure. Don't stop working on a class untill it's finished for now. Also, don't over-do the methods. Build stuff only when it's needed, and not think: "Hm, that would be cool to have". Cause most of the time you end up with unused code, and we don't want that.Build a unittest project and make sure you create the folder inside the project that it's testing. So, create the ChuckNorris.DataAccess.UnitTest project inside the folder of the dataaccess project. I would suggest using the nUnit testframework.Incase you though, hm i skip unittest: Don't! Just build it - it will safe you alot of time later onNow, read 5 again. Build that bloody unittest. Don't skip. (i cant emphasize this enough)Now, every class in the dataaccess project is responsible for itself. They don't rely on each other. This is where we use the BusinessLogic project for. Start creating the ChuckNorris.BusinessLogic project. (not inside the data-access project ofcourse, but withing the ChuckNorris folder.Combine stuff from data-access. This usual involves alot of copying the data-access classes and feels silly at first. (we'll get to that later on)Now you come up to a point of creating a service project. You might not always see why to use it, but see it as a way to expose your businesslogic to any application (including your own). Sometimes i use it as a so-called "Factory". Every call goes through this factory, so that's the only thing i'm exposing to any program, and make sure that those methods are the only ones that I allow you to invoke.Build any UI (website, phoneapp, forms application, silverlight, wpf or whatever) and reference it to you service project. Fall in love (cough) with this approach.It's possible that it doesn't seem to make much sense, and very incomplete. Well, that last part is correct. Next post will go in to detail of setting up your Data-Access project and use the entity framework.

• Oracle Service Cloud May 2014 Release – Focus on your driving by JP Saunders

  - by Tuula Fai

  The next time you’re twiddling dials on your car’s dashboard to get the air to blow in the right direction, and the right song to play on the stereo, while pulling on the wires to charge your phone and punching in passwords to re-sync your hands-free headset to take a call, consider this… Does having a better dashboard UI in your car improve your driving performance? The Tesla car has one of the most modern and intuitive dashboards in any commercial car today. It is actually based on the design of a smart phone, which can download apps and updates directly from the cloud.  The 17” touchscreen, Lynx-based dashboard totally integrates all channels and devices, allowing the driver to focus on the smooth driving and power of this luxury (toy) car.  What the folks at Tesla didn't do was avoid the complexity of our needs. Instead, they streamlined them. And, while we might not all be able to afford a Tesla, their approach demonstrates that a modern UI approach can ultimately make a positive difference in our lives and businesses.  This is why the productivity and effectiveness of a Modern Contact Center is many times greater than that of a traditional contact center. Agents in a Modern Contact Center get to focus on the task at hand, the customer engagement, rather than stumbling their way through Lego blocks of complexity.  The Oracle Service Cloud is a modern approach to customer service that empowers your agents to achieve greater focus on improving your operational and strategic success through streamlined business processes.  Here are some of the recent May 2014 release highlights to the Oracle Service Cloud: Performance Enhanced Desktop UI A modern agent desktop interface that optimizes clumsy tasks, logins, screens and workflows and is optimized for agent and system performance. Improvements include performance for drag-and-drop configurable views, saved searches, and improved caching for high-speed performance even during disconnected or slow internet access.  Customer Experience Routing A streamlined automatic way to connect the right customer need to the best agent skills, based on multidimensional variables such as product skills, language skills, workload, call volume to optimize the connection and resolution experience. On-The-Go Mobile Improvements to the Agent mobile app that extend connectivity to websites, and customer surveys that are mobile-ready and rendered for any device, and ensure the customer’s voice is captured while the insight is still top of mind.  Infused Social Engagement Enhancements to infused social capabilities allow agents to respond in social threads directly from within the agent desktop, with the information becoming part of the incident record for automatic actions (such as replay or escalate) triggered off the response. Front-End Siebel Contact Center The market leading online Web Customer Self-Service interface from the Oracle Service Cloud, is now out-of-the-box ready for Oracle Siebel customers. Deploy a new online web self-service interface in a matter of weeks to have customers self-serve and self-solve answers, with escalated incidents routed directly into the Oracle Siebel Contact Center. For more information on the latest enhancements for the Oracle Service Cloud, please see the Oracle Service Cloud May 2014 Capabilities and Benefits. Related blogs: Oracle Service Cloud Feb 2014

• Are there any concerns with using a static read-only unit of work so that it behaves like a cache?

  - by Rowan Freeman

  Related question: How do I cache data that rarely changes? I'm making an ASP.NET MVC4 application. On every request the security details about the user will need to be checked with the area/controller/action that they are accessing to see if they are allowed to view it. The security information is stored in the database. For example: User Permission UserPermission Action ActionPermission A "Permission" is a token that is applied to an MVC action to indicate that the token is required in order to access the action. Once a user is given the permission (via the UserPermission table) then they have the token and can therefore access the action. I've been looking in to how to cache this data (since it rarely changes) so that I'm only querying in-memory data and not hitting a database (which is a considerable performance hit at the moment). I've tried storing things in lists, using a caching provider but I either run in to problems or performance doesn't improve. One problem that I constantly run in to is that I'm using lazy loading and dynamic proxies with EntityFramework. This means that even if I ToList() everything and store them somewhere static, the relationships are never populated. For example, User.Permissions is an ICollection but it's always null. I don't want to Include() everything because I'm trying to keep things simple and generic (and easy to modify). One thing I know is that an EntityFramework DbContext is a unit of work that acts with 1st-level caching. That is, for the duration of the unit of work, everything that is accessed is cached in memory. I want to create a read-only DbContext that will exist indefinitely and will only be used to read about permission data. Upon testing this it worked perfectly; my page load times went from 200ms+ to 20ms. I can easily force the data to refresh at certain intervals or simply leave it to refresh when the application pool is recycled. Basically it will behave like a cache. Note that the rest of the application will interact with other contexts that exist per request as normal. Is there any disadvantage to this approach? Could I be doing something different?

• Problems using custom keyboard layout / symbols file

  - by January

  I have a custom xkb symbols file which looks as follows: // modify the basic German layout to have polish characters default partial alphanumeric_keys xkb_symbols "basic" { include "de(basic)" name[Group1]="Germany - with polish characters"; key <AD03> { [ e, E, eogonek, Eogonek ] }; key <AD09> { [ o, O, oacute, Oacute ] }; key <AC01> { [ a, A, aogonek, Aogonek ] }; key <AC02> { [ s, S, sacute, Sacute ] }; key <AD06> { [ z, Z, zabovedot, Zabovedot ] }; key <AB02> { [ x, X, zacute, Zacute ] }; key <AB03> { [ c, C, cacute, Cacute ] }; key <AB06> { [ n, N, nacute, Nacute ] }; }; The name of the file is depl. I copy the file to /usr/share/X11/xkb/symbols and it works with setxkbmap depl. However, I also tried to add the respective menu entries in the "Text Entry" customization. I have modified the file /usr/share/X11/xkb/rules/evdev.xml and added the following section: <layout> <configItem> <name>depl</name> <shortDescription>depl</shortDescription> <description>German (with Polish characters)</description> <languageList> <iso639Id>ger</iso639Id> </languageList> </configItem> </layout> I have then reconfigured the xkb data with sudo dpkg-reconfigure xkb-data. It works in as much as that the new layout appears as a viable option in the Text Entry dialog, it can be added to the list of dialogs and is visible in the application indicator: However, it does not work, the new symbols are not loaded. No errors are reported in /var/log/Xorg.0.log.
