• Using Content Analytics for More Effective Engagement

  - by Kellsey Ruppel

  Using Content Analytics for More Effective Engagement: Turning High-Volume Content into Templates for Success By Mitchell Palski, Oracle WebCenter Sales Consultant Many organizations use Oracle WebCenter Portal to develop these basic types of portals: Intranet portals used for collaboration, employee self-service, and company communication Extranet portals used by customers and partners for self-service and support Team collaboration portals that allow users to share documents and content, track activity, and engage in discussions Portals are intended to provide a personalized, single point of interaction with web-based applications and information. The user experiences that a Portal is capable of displaying should be relevant to an individual user or class of users (a group or role). The components of a Portal that would vary based on a user’s identity include: Web content such as images, news articles, and on-screen instruction Social tools such as threaded discussions, polls/surveys, and blogs Document management tools to upload, download, and edit files Web applications that present data visualizations and data entry modules These collections of content, tools, and applications make up valuable workspaces. The challenge that a development team may have is defining which combinations are the most effective for its users. No one wants to create and manage a workspace that goes un-used or (even worse) that is used but is ineffective. Oracle WebCenter Portal provides you with the capabilities to not only rapidly develop variations of portals, but also identify which portals are the most effective and should be re-used throughout an enterprise. Capturing Portal AnalyticsOracle WebCenter Portal provides an analytics service that allows administrators and business users to track and analyze portal usage. These analytics are captured in the form of: Usage tracking metrics Behavior tracking User Profile Correlation The out-of-the-box task reports that come with Oracle WebCenter Portal include: WebCenter Portal Traffic Page Traffic Login Metrics Portlet Traffic Portlet Response Time Portlet Instance Traffic Portlet Instance Response Time Search Metrics Document Metrics Wiki Metrics Blog Metrics Discussion Metrics Portal Traffic Portal Response Time By determining the usage and behavior tracking metrics that are associated with specific user profiles (including groups and roles), your administrators will be able to identify the components of your solution that are the most valuable.  Your first step as an administrator should be to identify the specific pages and/or components are used the most frequently. Next, determine the user(s) or user-group(s) that are accessing those high-use elements of a portal. It is also important to determine patterns in high-usage and see if they correlate to a specific schedule. One of the goals of any development team (especially those that are following Agile methodologies) should be to develop reusable web components to minimize redundant development. Oracle WebCenter Portal provides you the tools to capture the successful workspaces that have already been developed and identified so that they can be reused for similar user demographics. Re-using Successful PortalsWhen creating a new Portal in Oracle WebCenter, developers have the option to base that portal on a template that includes: Pre-seeded data such as pages, tools, user roles, and look-and-feel assets Specific sub-sets of page-layouts, tools, and other resources to standardize what is added to a Portal’s pages Any custom components that your team creates during development cycles Once you have identified a successful workspace and its most valuable components, leverage Oracle WebCenter’s ability to turn that custom portal into a portal template. By creating a template from your already successful portal, you are empowering your enterprise by providing a starting point for future initiatives. Your new projects, new teams, and new web pages can benefit from lessons learned and adjustments that have already been made to optimize user experiences instead of starting from scratch. ***For a complete explanation of how to work with Portal Templates, be sure to read the Fusion Middleware documentation available online.

• Pinterest and the Rising Power of Imagery

  - by Mike Stiles

  If images keep you glued to a screen, you’re hardly alone. Countless social users are letting their eyes do the walking, waiting for that special photo to grab their attention. And perhaps more than any other social network, Pinterest has been giving those eyes plenty of room to walk. Pinterest came along in 2010. Its play was that users could simply create topic boards and pin pictures to the appropriate boards for sharing. Yes there are some words, captions mostly, but not many. The speed of its growth raised eyebrows. Traffic quadrupled in the last quarter of 2011, with 7.51 million unique visitors in December alone. It now gets 1.9 billion monthly page views. And it was sticky. In the US, the average time a user spends strolling through boards and photos on Pinterest is 15 minutes, 50 seconds. Proving the concept of browsing a catalogue is not dead, it became a top 5 referrer for several apparel retailers like Land’s End, Nordstrom, and Bergdorfs. Now a survey of online shoppers by BizRate Insights says that Pinterest is responsible for more purchases online than Facebook. Over 70% of its users are going there specifically to keep up with trends and get shopping ideas. And when they buy, the average order value is $179. Pinterest is also scoring better in terms of user engagement. 66% of pinners regularly follow and repin retailers, whereas 17% of Facebook fans turn to that platform for purchase ideas. (Facebook still wins when it comes to reach and driving traffic to 3rd-party sites by the way). Social posting best practices have consistently shown that posts with photos are rewarded with higher engagement levels. You may be downright Shakespearean in your writing, but what makes images in the digital world so much more powerful than prose? 1. They transcend language barriers. 2. They’re fun and addictive to look at. 3. They can be consumed in fractions of a second, important considering how fast users move through their social content (admit it, you do too). 4. They’re efficient gateways. A good picture might get them to the headline. A good headline might then get them to the written content. 5. The audience for them surpasses demographic limitations. 6. They can effectively communicate and trigger an emotion. 7. With mobile use soaring, photos are created on those devices and easily consumed and shared on them. Pinterest’s iPad app hit #1 in the Apple store in 1 day. Even as far back as 2009, over 2.5 billion devices with cameras were on the streets generating in just 1 year, 10% of the number of photos taken…ever. But let’s say you’re not a retailer. What if you’re a B2B whose products or services aren’t visual? Should you worry about your presence on Pinterest? As with all things, you need a keen awareness of who your audience is, where they reside online, and what they want to do there. If it doesn’t make sense to put a tent stake in Pinterest, fine. But ignore the power of pictures at your own peril. If not visually, how are you going to attention-grab social users scrolling down their News Feeds at top speed? You’re competing with every other cool image out there from countless content sources. Bore us and we’ll fly right past you.

• College Ratings via the Federal Government

  - by user9147039

  A few weeks back you might remember news about a higher education rating system proposal from the Obama administration. As I've discussed previously, political and stakeholder pressures to improve outcomes and increase transparency are stronger than ever before. The executive branch proposal is intended to make progress in this area. Quoting from the proposal itself, "The ratings will be based upon such measures as: Access, such as percentage of students receiving Pell grants; Affordability, such as average tuition, scholarships, and loan debt; and Outcomes, such as graduation and transfer rates, graduate earnings, and advanced degrees of college graduates.” This is going to be quite complex, to say the least. Most notably, higher ed is not monolithic. From community and other 2-year colleges, to small private 4-year, to professional schools, to large public research institutions…the many walks of higher ed life are, well, many. Designing a ratings system that doesn't wind up with lots of unintended consequences and collateral damage will be difficult. At best you would end up potentially tarnishing the reputation of certain institutions that were actually performing well against the metrics and outcome measures that make sense in their "context" of education. At worst you could spend a lot of time and resources designing a system that would lose credibility with its "customers". A lot of institutions I work with already have in place systems like the one described above. They are tracking completion rates, completion timeframes, transfers to other institutions, job placement, and salary information. As I talk to these institutions there are several constants worth noting: • Deciding on which metrics to measure is complicated. While employment and salary data are relatively easy to track, qualitative measures are more difficult. How do you quantify the benefit to someone who studies in one field that may not compensate him or her as well as another field but that provides huge personal fulfillment and reward is a difficult measure to quantify? • The data is available but the systems to transform the data into actual information that can be used in meaningful ways are not. Too often in higher ed information is siloed. As such, much of the data that need to be a part of a comprehensive system sit in multiple organizations, oftentimes outside the reach of core IT. • Politics and culture are big barriers. One of the areas that my team and I spend a lot of time talking about with higher ed institutions all over the world is the imperative to optimize for student success. This, like the tracking of the students’ achievement after graduation, requires a level or organizational capacity that does not currently exist. The primary barrier is the culture of "data islands" in higher ed, and the need for leadership to drive out the divisions between departments, schools, colleges, etc. and institute academy-wide analytics and data stewardship initiatives that will enable student success. • Data quality is a very big issue. So many disparate systems exist (some on premise, some "in the cloud") that keep data about "persons" using different means to identify them. Establishing a single source of truth about an individual and his or her data is difficult without some type of data quality policy and tools. Good tools actually exist but are seldom leveraged. Don't misunderstand - I think it's a great idea to drive additional transparency and accountability into the system of higher education. And not just at home, but globally. Students and parents need access to key data to make informed, responsible choices. The tools exist to not only enable this kind of information to be shared but to capture the very metrics stakeholders care most about and in a way that makes sense in the context of a given institution's "place" in the overall higher ed panoply.

• Spotlight on Oracle Social Relationship Management. Social Enable Your Enterprise with Oracle SRM.

  - by Pat Ma

  Facebook is now the most popular site on the Internet. People are tweeting more than they send email. Because there are so many people on social media, companies and brands want to be there too. They want to be able to listen to social chatter, engage with customers on social, create great-looking Facebook pages, and roll out social-collaborative work environments within their organization. This is where Oracle Social Relationship Management (SRM) comes in. Oracle SRM is a product that allows companies to manage their presence with prospects and customers on social channels. Let's talk about two popular use cases with Oracle SRM. Easy Publishing - Companies now have an average of 178 social media accounts - with every product or geography or employee group creating their own social media channel. For example, if you work at an international hotel chain with every single hotel creating their own Facebook page for their location, that chain can have well over 1,000 social media accounts. Managing these channels is a mess - with logging in and out of every account, making sure that all accounts are on brand, and preventing rogue posts from destroying the brand. This is where Oracle SRM comes in. With Oracle Social Relationship Management, you can log into one window and post messages to all 1,000+ social channels at once. You can set up approval flows and have each account generate their own content but that content must be approved before publishing. The benefits of this are easy social media publishing, brand consistency across all channels, and protection of your brand from inappropriate posts. Monitoring and Listening - People are writing and talking about your company right now on social media. 75% of social media users have written a negative post about a brand after a poor customer service experience. Think about all the negative posts you see in your Facebook news feed about delayed flights or being on hold for 45 minutes. There is so much social chatter going on around your brand that it's almost impossible to keep up or comprehend what's going on. That's where Oracle SRM comes in. With Social Relationship Management, a company can monitor and listen to what people are saying about them on social channels. They can drill down into individual posts or get a high level view of trends and mentions. The benefits of this are comprehending what's being said about your brand and its competitors, understanding customers and their intent, and responding to negative posts before they become a PR crisis. Oracle SRM is part of Oracle Cloud. The benefits of cloud deployment for customers are faster deployments, less maintenance, and lower cost of ownership versus on-premise deployments. Oracle SRM also fits into Oracle's vision to social enable your enterprise. With Oracle SRM, social media is not just a marketing channel. Social media is also mechanism for sales, customer support, recruiting, and employee collaboration. For more information about how Oracle SRM can social enable your enterprise, please visit oracle.com/social. For more information about Oracle Cloud, please visit cloud.oracle.com.

• Identity in .NET 4.5&ndash;Part 3: (Breaking) changes

  - by Your DisplayName here!

  I recently started porting a private build of Thinktecture.IdentityModel to .NET 4.5 and noticed a number of changes. The good news is that I can delete large parts of my library because many features are now in the box. Along the way I found some other nice additions. ClaimsIdentity now has methods to query the claims collection, e.g. HasClaim(), FindFirst(), FindAll(). ClaimsPrincipal has those methods as well. But they work across all contained identities. Nice! ClaimsPrincipal.Current retrieves the ClaimsPrincipal from Thread.CurrentPrincipal. Combined with the above changes, no casting necessary anymore. SecurityTokenHandler now has read and write methods that work directly with strings. This makes it much easier to deal with non-XML tokens like SWT or JWT. A new session security token handler that uses the ASP.NET machine key to protect the cookie. This makes it easier to get started in web farm scenarios. No need for a custom service host factory or the federation behavior anymore. WCF can be switched into “WIF mode” with the useIdentityConfiguration switch (odd name though). Tooling has become better and the new test STS makes it very easy to get started. On the other hand – and that was kind of expected – to bring claims into the core framework, there are also some breaking changes for WIF code. If you want to migrate (and I would recommend that), most changes to your code are mechanical. The following is a brain dump of the changes I encountered. Assembly Microsoft.IdentityModel is gone. The new functionality is now in mscorlib, System.IdentityModel(.Services) and System.ServiceModel. All the namespaces have changed as well. No IClaimsPrincipal and IClaimsIdentity anymore. Configuration section has been split into <system.identityModel /> and <system.identityModel.services />. WCF configuration story has changed as well. Claim.ClaimType is now Claim.Type. ClaimCollection is now IEnumerable<Claim>. IsSessionMode is now IsReferenceMode. Bootstrap token handling is different now. ClaimsPrincipalHttpModule is gone. This is not really needed anymore, apart from maybe claims transformation (see here). Various factory methods on ClaimsPrincipal are gone (e.g. ClaimsPrincipal.CreateFromIdentity()). SecurityTokenHandler.ValidateToken now returns a ReadOnlyCollection<ClaimsIdentity>. Some lower level helper classes are gone or internal now (e.g. KeyGenerator). The WCF WS-Trust bindings are gone. I think this is a pity. They were *really* useful when doing work with WSTrustChannelFactory. Since WIF is part of the Windows operating system and also supported in future versions of .NET, there is no urgent need to migrate to the 4.5 claims model. But obviously, going forward, at some point you want to make the move.

• Challenges in Corporate Reporting - New Independent Research

  - by ndwyouell

  Earlier this year, Oracle and Accenture sponsored a global study on trends in financial close and reporting. We surveyed 1,123 finance professionals in large organizations in 12 countries around the world during February and March. Financial Consolidation and Reporting is the most mature aspect of Enterprise Performance Management with mainstream solutions having been around for over 30 years. But of course over this time there have been many changes and very significant increases in regulation. So just what is the current state is Financial Consolidation and Reporting in our major corporations across the world? We commissioned this independent research to find out. Highlights of the result are: •          Seeking change: Businesses recognize they need to invest in financial reporting to address the challenges they currently face. 47 percent of companies have made substantial investments over the last year to the financial close, filing, and reporting processes. •          Ineffective investments: Despite these investments, spreadsheets (72 percent) and e-mails (68 percent) are still being used daily to track and manage reporting, suggesting that new investments are falling short of expectations. •          Increased costs and uncertainty: The situation is so opaque that managers across the finance function are unable to fully understand the financial impact or cost implications of reporting, with 60 percent of respondents admitting they did not know the total cost of managing and publicizing their financial results. •          Persistent challenges: 68 percent of respondents admitted that they have inadequate visibility into reporting processes, while 84 percent of finance managers surveyed said they find it difficult to control the quality of financial data across the entire reporting process. •          Decreased effectiveness: 71 percent of finance managers feel their effectiveness is limited in some way by data-analysis–related issues, while 39 percent of C-level or VP-level respondents say their effectiveness is impaired by limited visibility. •          Missed deadlines: Due to late changes to the chart of accounts, 15 percent of global businesses have missed statutory filings, putting their companies at risk of financial penalties and potentially impacting share value. The report makes it clear that investments made to date by these large organizations around the world have been uneven across the close, reporting, and filing processes, which has led to the challenges these organizations currently face in the overall process. Regardless of whether companies are using a variety of solutions or a single solution, the report shows they continue to witness increased costs, ineffectual data management, and missed reporting, which—in extreme circumstances—can impact a company’s corporate image and share value. The good news is that businesses realize that these problems persist and 86 percent of companies are likely to make a significant investment during the next five years to address these issues. While they should invest, it is critical that they direct investments correctly to address the key issues this research identified: •          Improving data integrity •          Optimizing processes •          Integrating the extended financial close process By addressing these issues and with clear guidance on how to implement the correct business processes, infrastructure, and software solutions, finance teams will find that their reporting processes are much more effective, cost-efficient, and aligned with their performance expectations.

• Selective Suppression of Log Messages

  - by Duncan Mills

  Those of you who regularly read this blog will probably have noticed that I have a strange predilection for logging related topics, so why break this habit I ask?  Anyway here's an issue which came up recently that I thought was a good one to mention in a brief post.  The scenario really applies to production applications where you are seeing entries in the log files which are harmless, you know why they are there and are happy to ignore them, but at the same time you either can't or don't want to risk changing the deployed code to "fix" it to remove the underlying cause. (I'm not judging here). The good news is that the logging mechanism provides a filtering capability which can be applied to a particular logger to selectively "let a message through" or suppress it. This is the technique outlined below. First Create Your Filter  You create a logging filter by implementing the java.util.logging.Filter interface. This is a very simple interface and basically defines one method isLoggable() which simply has to return a boolean value. A return of false will suppress that particular log message and not pass it onto the handler. The method is passed the log record of type java.util.logging.LogRecord which provides you with access to everything you need to decide if you want to let this log message pass through or not, for example  getLoggerName(), getMessage() and so on. So an example implementation might look like this if we wanted to filter out all the log messages that start with the string "DEBUG" when the logging level is not set to FINEST:  public class MyLoggingFilter implements Filter {     public boolean isLoggable(LogRecord record) {         if ( !record.getLevel().equals(Level.FINEST) && record.getMessage().startsWith("DEBUG")){          return false;            }         return true;     } } Deploying   This code needs to be put into a JAR and added to your WebLogic classpath.  It's too late to load it as part of an application, so instead you need to put the JAR file into the WebLogic classpath using a mechanism such as the PRE_CLASSPATH setting in your domain setDomainEnv script. Then restart WLS of course. Using The final piece if to actually assign the filter.  The simplest way to do this is to add the filter attribute to the logger definition in the logging.xml file. For example, you may choose to define a logger for a specific class that is raising these messages and only apply the filter in that case.  <logger name="some.vendor.adf.ClassICantChange"         filter="oracle.demo.MyLoggingFilter"/> You can also apply the filter using WLST if you want a more script-y solution.

• Create Custom Speech Bubbles in Silverlight.

  - by mbcrump

  I had a reader email me the following question: “How do you create Speech Bubbles in Silverlight/WPF without adding any extra .dlls? Right off the bat, I know at least two ways to create the speech bubbles that look just like the ones in comic books. Using the Callout Shapes included with Blend 4. Using the free 3rd party control named FreeBubbles (I used this before Blend 4). Unfortunately, we cannot use either of these as they will both add extra .dll’s to the project. So why wouldn’t you want to use one of those? I can think of a few reasons: You do not want to increase the size of your .XAP by including extra .dll’s. You do not have Expression Blend or the license to the use the .dll’s. You want a custom Speech Bubble that is not included in the four “Callout” Controls with Blend. Instead of using one of these methods, we will create a Speech Bubble in Blend 4 using Path element and a TextBlock. Before we get started, lets look at the Callout Shapes included with Blend 4. Using Blend 4 you can simply drag/drop these controls onto your Silverlight application and you are ready to go. We can create all of these Speech Bubbles and even some of the modern bubbles used in recent comic books. Lets get started. Start up Expression Blend 4 and select the Pen Tool. On the Art Board, start connecting the dots like I did below. You can add a color if you wish. …keep going …complete Let’s go ahead and add some text to the Speech Bubble. Drag a TextBlock from the Panel and put it directly inside the Speech Bubble. Go ahead and set the TextAlignment to Center for the TextBlock. and give it some text. At this point, you could go ahead and create a user control if you want to reuse the Speech Bubble you created. Select both the Path and the TextBlock by clicking then while holding down CTRL and then Right Click them. Select Make Into User Control. Give it a name and then Build your project. Lets create another one using the Ellipse for the older comic book style of Speech Bubbles. Drag an Ellipse to the Artboard and give it a color. Now, grab the Pen and drag a triangle like I did below. Simply drag it over a corner of the Ellipse. Select Combine then Unite and you will have a Path. At this point, you can go ahead and add a TextBlock like we did earlier. Lets go ahead and create a rounded rectangle one by adding a Rectangle to the Artboard. Go ahead and set the RadiuX and RadiusY to 25 to give it rounded edges. Let’s create another path and drag it right on top of our rounded rectangle like we did earlier. …looking good Select Combine then Unite and you will have a Path. At this point, you can go ahead and add a TextBlock like we did earlier. So let’s look at what we’ve created today using the path element and TextBlock. As you can tell, it required more work but meets the requirements. This was actually fun to do and I encourage anyone that visits my blog to send in request like this.  Subscribe to my feed

• Taking a look at the Mindscape Phone Elements for WP7.

  - by mbcrump

  I recently heard that Mindscape HQ had released the Windows Phone 7 Controls and had to take a look at them. 100 FREE LICENSE GIVEAWAY! Before we get to the screenshots, you will be pleased to learn that my usergroup called “Allaboutxaml” has partnered with Mindscape HQ and are giving away 100 license. You can check out the site here to get your free controls. But please hurry as after the 100 are gone then I will not have any more to give away! A few links to read first: The official blog post from Mindscape HQ detailing the release. They also have the links to download the trial and get started. The phone elements official forum! So, let’s get started. After you download the controls go ahead and double click the .exe to get started installing them. After everything is installed then you will have the following program group. I’d recommend clicking on the Phone Elements Directory to get started: Let’s go over each element: Bin – Just the .DLL that’s required to use Mindscape HQ WP7 Controls in your project. Documentation – a .CHM File that will show you how to get your project up and running quickly. Resources – Just a few image files Samples – This is a full WP7 project that details every controls. The thing that I was most interested in was how the controls look and is it easy to use. I always believed if your paying for controls then you should hold my hand through using them. You will be pleased to know that Mindscape made it very easy to use. First, the WP7 project in the “Samples” folder just works. Double click on the solution file and you are in an emulator looking at the controls. Since you have the source code for every control, it’s a matter of copying/pasting the code in your project to get it to work. What I did, was play with the controls in the emulator until I found one I could use. Then I looked at the Visual Studio solution and found the Page that contained the control. Mindscape makes this very easy to do with their layout: So, the one that I was interested in was the Looping List Box.  Here is a demo of it: I wanted to see how they were populating the numbers 1-100 so I found the code behind and noticed it was just this one line. LoopingListBox1.DataSource = new NumericDataSource() { MinValue = 1, MaxValue = 100 }; In case you are wondering, the NumericDataSource was created by MindScape and you can view the Declaration to find out more about it:   So, the controls are pretty much that easy to use. Play with the emulator and find the control you want to use. Find the XAML file in the Sample Solution and copy/paste the code. Let’s go ahead and take a look at the controls available: They also have a great variety of Charting controls: Overall it’s a nice set of WP7 controls. Feel free to leave a comment below on anything you would like to see and I will make sure that Mindscape HQ get the message. Don’t forget if you are the first 100 people reading this article then you will get a free license.  Subscribe to my feed CodeProject

• bulk insert and update with ADO.NET Entity Framework

  - by Keith Barrows

  I am writing a small application that does a lot of feed processing. I want to use LINQ EF for this as speed is not an issue, it is a single user app and, in the end, will only be used once a month. My questions revolves around the best way to do bulk inserts using LINQ EF. After parsing the incoming data stream I end up with a List of values. Since the end user may end up trying to import some duplicate data I would like to "clean" the data during insert rather than reading all the records, doing a for loop, rejecting records, then finally importing the remainder. This is what I am currently doing: DateTime minDate = dataTransferObject.Min(c => c.DoorOpen); DateTime maxDate = dataTransferObject.Max(c => c.DoorOpen); using (LabUseEntities myEntities = new LabUseEntities()) { var recCheck = myEntities.ImportDoorAccess.Where(a => a.DoorOpen >= minDate && a.DoorOpen <= maxDate).ToList(); if (recCheck.Count > 0) { foreach (ImportDoorAccess ida in recCheck) { DoorAudit da = dataTransferObject.Where(a => a.DoorOpen == ida.DoorOpen && a.CardNumber == ida.CardNumber).First(); if (da != null) da.DoInsert = false; } } ImportDoorAccess newIDA; foreach (DoorAudit newDoorAudit in dataTransferObject) { if (newDoorAudit.DoInsert) { newIDA = new ImportDoorAccess { CardNumber = newDoorAudit.CardNumber, Door = newDoorAudit.Door, DoorOpen = newDoorAudit.DoorOpen, Imported = newDoorAudit.Imported, RawData = newDoorAudit.RawData, UserName = newDoorAudit.UserName }; myEntities.AddToImportDoorAccess(newIDA); } } myEntities.SaveChanges(); } I am also getting this error: System.Data.UpdateException was unhandled Message="Unable to update the EntitySet 'ImportDoorAccess' because it has a DefiningQuery and no element exists in the element to support the current operation." Source="System.Data.SqlServerCe.Entity" What am I doing wrong? Any pointers are welcome.

• ASP.NET MVC tries to load older version of Owin assembly

  - by d_mcg

  As a bit of context, I'm developing an ASP.NET MVC 5 application that uses OAuth-based authentication via Microsoft's OWIN implementation, for Facebook and Google only at this stage. Currently (as of v3.0.0, git-commit 4932c2f), the FacebookAuthenticationOptions and GoogleOAuth2AuthenticationOptions don't provide any property to force Facebook nor Google respectively to reauthenticate users (via appending the appropriate query string parameters) when signing in. Initially, I set out to override the following classes: FacebookAuthenticationOptions GoogleOAuth2AuthenticationOptions FacebookAuthenticationHandler (specifically AuthenticateCoreAsync()) GoogleOAuth2AuthenticationHandler (specifically AuthenticateCoreAsync()) yet discovered that the ~AuthenticationHandler classes are marked as internal. So I pulled a copy of the source for the Katana project (http://katanaproject.codeplex.com/) and modified the source accordingly. After compiling, I found that there are several dependencies that needed updating in order to use these updated assemblies (Microsoft.Owin.Security.Facebook and Microsoft.Owin.Security.Google) in the MVC project: Microsoft.Owin Microsoft.Owin.Security Microsoft.Owin.Security.Cookies Microsoft.Owin.Security.OAuth Microsoft.Owin.Host.SystemWeb This was done by replacing the existing project references to the 3.0.0 versions and updating those in web.config. Good news: the project compiles successfully. In debugging, I received an exception on startup: An exception of type 'System.IO.FileLoadException' occurred in [MVC web assembly].dll but was not handled in user code Additional information: Could not load file or assembly 'Microsoft.Owin.Security, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) The underlying exception indicated that Microsoft.AspNet.Identity.Owin was trying to load v2.1.0 of Microsoft.Owin.Security when calling app.UseExternalSignInCookie() from Startup.ConfigureAuth(IAppBuilder app) in Startup.Auth.cs. Unfortunately that assembly (and its other dependency, Microsoft.AspNet.Identity.Owin) aren't part of the Project Katana solution, and I can't find any accessible repository for these assemblies online. Are the Microsoft.AspNet.Identity assemblies open source, like the Katana project? Is there a way to fool those assemblies to use the referenced v3.0.0 assemblies instead of v2.1.0? The /bin folder contains the 3.0.0 versions of the Owin assemblies. I've upgraded the NuGet packages for Microsoft.AspNet.Identity.Owin, and this is still an issue. Any ideas on how to resolve this issue?

• What good technology podcasts are out there?

  - by Michael Stum

  Yes, Podcasts, those nice little Audiobooks I can listen to on the way to work. With the current amount of Podcasts, it's like searching a needle in a haystack, except that the haystack happens to be the Internet and is filled with too many of these "Hot new Gadgets" stuff :( Now, even though I am mainly a .NET developer nowadays, maybe anyone knows some good Podcasts from people regarding the whole software lifecycle?

• Creating an IIS 6 Virtual Directory with PowerShell v2 over WMI/ADSI

  - by codepoke

  I can create an IISWebVirtualDir or IISWebVirtualDirSetting with WMI, but I've found no way to turn the virtual directory into an IIS Application. The virtual directory wants an AppFriendlyName and a Path. That's easy because they're part of the ...Setting object. But in order to turn the virtual directory into an App, you need to set AppIsolated=2 and AppRoot=[its root]. I cannot do this with WMI. I'd rather not mix ADSI and WMI, so if anyone can coach me through to amking this happen in WMI I'd be very happy. Here's my demo code: $server = 'serverName' $site = 'W3SVC/10/ROOT/' $app = 'AppName' # If I use these args, the VirDir is not created at all. Fails to write read-only prop # $args = @{'Name'=('W3SVC/10/ROOT/' + $app); ` # 'AppIsolated'=2;'AppRoot'='/LM/' + $site + $app} # So I use this single arg $args = @{'Name'=($site + $app)} $args # Look at the args to make sure I'm putting what I think I am $v = set-wmiinstance -Class IIsWebVirtualDir -Authentication PacketPrivacy ` -ComputerName $server -Namespace root\microsoftiisv2 -Arguments $args $v.Put() # VirDir now exists # Pull the settings object for it and prove I can tweak it $filter = "Name = '" + $site + $app + "'" $filter $v = get-wmiobject -Class IIsWebVirtualDirSetting -Authentication PacketPrivacy ` -ComputerName $server -Namespace root\microsoftiisv2 -Filter $filter $v.AppFriendlyName = $app $v.Put() $v # Yep. Changes work. Goes without saying I cannot change AppIsolated or AppRoot # But ADSI can change them without a hitch # Slower than molasses in January, but it works $a = [adsi]("IIS://$server/" + $site + $app) $a.Put("AppIsolated", 2) $a.Put("AppRoot", ('/LM/' + $site + $app)) $a.Put("Path", "C:\Inetpub\wwwroot\news") $a.SetInfo() $a Any thoughts?

• Azure - Unable To Get SQL Azure Invitation Code!

  - by Goober

  Scenario I'm trying to convert my Silverlight Business Application over to the cloud with the help of Azure. I have been following this link from Brad Abrams blog. Both the links to Windows Azure and SQL Azure crash out in Google Chrome, they work in Internet Explorer, but it's literally one of the worst user experiences I've ever had. The Problem I'm asked to sign in to Microsoft connect with my Live ID. I do so, I'm then asked to register!? - I do so. I'm then sent a verification email which I verify. I'm then signed out!?!?! When I sign back in, it repeats the process.... ANY IDEAS!??! Edit/Update: Finally managed to get signed up/in to connect. From here I was able to get hold of an invitation code to Windows Azure. Now I need an invitation code for SQL Azure. I cannot see ANYWHERE that advertises a way of getting this SQL Azure code, the only thing that I have seen is some text saying that there "may be a delay" in receiving codes due to volume of interest, which quite frankly I find hard to believe......... It's so far been 3 days now.This officially Sucks! If I have any more news I'll post back here.

• How do I properly host a WCF Data Service in IIS? Why am I getting errors?

  - by j0rd4n

  I'm playing around with WCF Data Services (ADO.NET Data Services). I have an entity framework model pointed at the AdventureWorks database. When I debug my svc file from within Visual Studio, it works great. I can say /awservice.svc/Customers and get back the ATOM feed I expect. If I publish the service (hosted in an ASP.NET web application) to IIS7, the same query string returns a 500 fault. The root svc page itself works as expected and successfully returns ATOM. The /Customers path fails. Here is what my grants look like in the svc file: public class AWService : DataService<AWEntities> { public static void InitializeService( DataServiceConfiguration config ) { config.SetEntitySetAccessRule( "*", EntitySetRights.All ); config.SetServiceOperationAccessRule( "*", ServiceOperationRights.All ); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } Update: I enabled verbose errors and get the following in the XML message: <innererror> <message>The underlying provider failed on Open.</message> <type>System.Data.EntityException</type> <stacktrace> at System.Data.EntityClient.EntityConnection.OpenStoreConnectionIf( ... ... <internalexception> <message> Login failed for user 'IIS APPPOOL\DefaultAppPool'. </message> <type>System.Data.SqlClient.SqlException</type> <stacktrace> at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, ...

• Android ASync task ProgressDialog isn't showing until background thread finishes

  - by jackbot

  I've got an Android activity which grabs an RSS feed from a URL, and uses the SAX parser to stick each item from the XML into an array. This all works fine but, as expected, takes a bit of time, so I want to use AsyncActivity to do it in the background. My code is as follows: class AddTask extends AsyncTask<Void, Item, Void> { protected void onPreExecute() { pDialog = ProgressDialog.show(MyActivity.this,"Please wait...", "Retrieving data ...", true); } protected Void doInBackground(Void... unused) { items = parser.getItems(); for (Item it : items) { publishProgress(it); } return(null); } protected void onProgressUpdate(Item... item) { adapter.add(item[0]); } protected void onPostExecute(Void unused) { pDialog.dismiss(); } } Which I call in onCreate() with new AddTask().execute(); The line items = parser.getItems() works fine - items being the arraylist containing each item from the XML. The problem I'm facing is that on starting the activity, the ProgressDialog which i create in onPreExecute() isn't displayed until after the doInBackground() method has finished. i.e. I get a black screen, a long pause, then a completely populated list with the items in. Why is this happening? Why isn't the UI drawing, the ProgressDialog showing, the parser getting the items and incrementally adding them to the list, then the ProgressDialog dismissing?

• "Trying to get property of non-object" error with SimpleXML and PHP

  - by SooDesuNe

  I'm using a PHP script with SimpleXML to parse an XML feed. I have no control over the content of the XML. try { $xml = @new SimpleXMLElement($fetchResult); } catch (Exception $e) { errorHandle($e->getMessage());} $userNick = $xml->View->ScrollView->VBoxView->View->MatrixView->VBoxView[0]->HBoxView->TextView->SetFontStyle->b; foreach ($xml->View->ScrollView->VBoxView->View->MatrixView->VBoxView[0]->VBoxView as $pathToSubTree){ foreach ($pathToSubTree->MatrixView->View->VBoxView->VBoxView->HBoxView[0]->VBoxView->MatrixView->VBoxView as $canopy){ //Do some stuff now that we've found the canopy of the tree } $canopy = $pathToSubTree->MatrixView->View->VBoxView->VBoxView->HBoxView[0]->VBoxView->MatrixView->VBoxView; if(is_null($canopy)){ //Do some stuff stuff is the canopy was not traceable } } $pathToSubTree = $xml->View->ScrollView->VBoxView->View->MatrixView->VBoxView[0]->VBoxView; if(is_null($pathToSubTree)){ //Do some stuff stuff is the subTree path was not traceable } unset($xml); I'm getting lots of two errors, which I'm sure are related to the same cause: PHP Notice: Trying to get property of non-object in myScript.php on line 45 PHP Warning: Invalid argument supplied for foreach() in myScript.php on line 45 PHP Notice: Trying to get property of non-object in myScript.php on line 76 Line 45 is (from above): foreach ($pathToSubTree->MatrixView->View->VBoxView->VBoxView->HBoxView[0]->VBoxView->MatrixView->VBoxView as $canopy){ Line 76 is (from above): $canopy = $pathToSubTree->MatrixView->View->VBoxView->VBoxView->HBoxView[0]->VBoxView->MatrixView->VBoxView; I'm pretty sure this error is caused by one of the arrays in my path not being an array for the particular XML, but some times it CAN be an array. What's the correct way to deal with these?

• Model validation with enumerable properties in Asp.net MVC2 RTM

  - by Robert Koritnik

  I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

• Streaming to the Android MediaPlayer

  - by Rob Szumlakowski

  Hi. I'm trying to write a light-weight HTTP server in my app to feed dynamically generated MP3 data to the built-in Android MediaPlayer. I am not permitted to store my content on the SD card. My input data is essentially of an infinite length. I tell MediaPlayer that its data source should basically be something like "http://localhost/myfile.mp3". I've a simple server set up that waits for MediaPlayer to make this request. However, MediaPlayer isn't very cooperative. At first, it makes an HTTP GET and tries to grab the whole file. It times out if we try and simply dump data into the socket so we tried using the HTTP Range header to write data in chunks. MediaPlayer doesn't like this and doesn't keep requesting the subsequent chunks. Has anyone had any success streaming data directly into MediaPlayer? Do I need to implement an RTSP or Shoutcast server instead? Am I simply missing a critical HTTP header? What strategy should I use here? Rob Szumlakowski

• How to use HTTP Live Streaming protocol in iPhone SDk 3.0

  - by Pugal Devan

  Hi Guys, i have developed on IPhone application and submitted to App store. But my application got rejected based on below criteria. Thank you for submitting your yyyyyyyy application. We have reviewed your application and have determined that it cannot be posted to the App Store at this time because it is not using the HTTP Live Streaming protocol to broadcast streaming video. HTTP Live Streaming is required when streaming video feeds over the cellular network, in order to have an optimal user experience and utilize cellular best practices. This protocol automatically determines bandwidth available to users and adjusts the bandwidth appropriately, even as bandwidth streams change. This allows you the flexibility to have as many streams as you like, as long as 64 kbps is set as the baseline feed. In my apps i have to stream prerecorded m4v and mp3 files from my server. I used MPMoviePlayerController to stream and play those videos / audio. How to implement the HTTP Live Streaming Protocol in my apps? Also can i get some sample code? Thanks in advance!

• 2 jQuery plugins don't seem to work together

  - by Carbonara

  I have 2 plugins, amongst several others, that are loaded together. All of them work together correctly expect 2. By commenting out bits of code etc I've narrowed it down to the two plugins. These are the 2 plugins in question jQuery Tools tabs and NewsTicker I have tried calling them as follows as per their instructions $(document).ready(function(){ $().newsTicker({ newsList: "#news", startDelay: 10, placeHolder1: " []" }); $("ul.tabs").tabs("div.panes > div"); }); With the calls this way around the ticker works but the tabs do not. If I swap the calls round then the tabs work but the ticker does not. Both plugins work if the other call is commented out. Any ideas what could be wrong here or could something in the code of one of the plugins be affecting the other. Both plugins work ok when several other plugins are also called in the same script. I'm just wondering if I'm calling them in the wrong way or something being fairly new to jQuery

• Using NSXMLParser with CDATA

  - by Robb

  I'm parsing an RSS feed with NSXMLParser and it's working fine for the title and other strings but one of the elements is an image thats like <!CDATA <a href="http:image..etc> How do I add that as my cell image in my table view? Would I define that as an image type? This is what i'm using to do my parsing: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ //NSLog(@"found this element: %@", elementName); currentElement = [elementName copy]; if ([elementName isEqualToString:@"item"]) { // clear out our story item caches... item = [[NSMutableDictionary alloc] init]; currentTitle = [[NSMutableString alloc] init]; currentDate = [ [NSMutableString alloc] init]; currentSummary = [[NSMutableString alloc] init]; currentLink = [[NSMutableString alloc] init]; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{ //NSLog(@"ended element: %@", elementName); if ([elementName isEqualToString:@"item"]) { // save values to an item, then store that item into the array...

• OCR: How to improve accuracy - existing libraries for removing non-text 'furniture', shapes, etc to

  - by Rob

  I want to remove rectangles etc that enclose text in a screenshot image, so that I can perform optical character recognition to get accurate text from the screenshot. Background: I doing this to extract data from a legacy application for use with other applications. This is the only way to get at this data as associated files are in a closed, proprietary, binary format. I will be using AutoItScript to drive the application to show data in its UI, then I will screenshot this and feed this to tesseract. I've already had some success in automating the UI, and have been able to use tesseract to get plain ascii text out of the bitmap. There are several AutoItScripr forum articles discussing its use with tesseract/OCR but not specifically for my question. http://www.autoitscript.com/forum/index.php?s=6c32c3ece12756e635a619cdf175eff9&showforum=2 What I need to do There are thin, 1-pixel wide rectangles that closely enclose some text, when fed to tesseract, it sees them as I for example for a verticle line of the rectangle. Any thoughts on how to remove the rectangles, or best practices? I'm asking if there is a generic command line based toolset to overwrite rectangles, for example, in .png files. I could then pass the .png through this, then pass it to tesseract. Details on the tesseract release/setup I've used are as follows: Go here: http://code.google.com/p/tesseract-ocr/downloads/list - For the basic english generic character set to get Tesseract up and running and recognising your bitmapped text into ascii text, use tesseract-2.00.eng.tar.gz (current version at time of writing is: "English language data for Tesseract (2.00 and up) Jul 2007 989 KB 84845") Related questions I have already looked at on Stack Overflow http://stackoverflow.com/questions/1335581/how-to-give-best-chance-of-success-to-an-ocr-software http://stackoverflow.com/questions/2296568/analysis-and-transformation-of-the-image-on-the-basis-of-this-analysis-for-better http://stackoverflow.com/questions/2268028/reading-characters-off-of-the-screen In these, my question is not completely answered or a commercial solution is being sold. I do not want to consider a commercial solution at this stage.

• FullCalendar and events: function

  - by Ernest

  I am trying to display my events from a MySQL database. I'm using the events function. My XML file being returned is pretty basic. I've looked at all of the FullCalendar questions and most of them talk about JSON and point to the documentation for JSON. I can't use JSON. I have to go XML. Can you tell me where I'm off. Here is a sample of what my xml looks like: Grow Your Business on the Web 2010-06-05T9:30 2010-06-05T12:30 O The whole file is prefaced with a tag and closed with a tag. My jquery is as follows: $(document).ready(function() { $('#calendar').fullCalendar({ height: 550, theme: true, header: { left: 'prev,next today', center: 'title', right: 'month,agendaWeek,agendaDay' }, editable: true, events: function(start, end, callback) { $.ajax({ url: 'ncludeFiles/sbdp-cal-xml.php', dataType: 'xml', data: { // our hypothetical feed requires UNIX timestamps start: Math.round(start.getTime() / 1000), end: Math.round(end.getTime() / 1000) }, success: function(doc) { var events = []; $(doc).find('event').each(function() { events.push({ title: $(this).attr('title'), start: $(this).attr('start'), end: $(this).attr('end'), className: $(this).attr('className'), url: $(this).attr('url') }); }); callback(events); } }); } }); }); I'd appreciate any help you could give me. Thanks!
