• Need WIF Training?

  - by Your DisplayName here!

  I spend numerous hours every month answering questions about WIF and identity in general. This made me realize that this is still quite a complicated topic once you go beyond the standard fedutil stuff. My good friend Brock and I put together a two day training course about WIF that covers everything we think is important. The course includes extensive lab material where you take standard application and apply all kinds of claims and federation techniques and technologies like WS-Federation, WS-Trust, session management, delegation, home realm discovery, multiple identity providers, Access Control Service, REST, SWT and OAuth. The lab also includes the latest version of the thinktecture identityserver and you will learn how to use and customize it. If you are looking for an open enrollment style of training, have a look here. Or contact me directly! The course outline looks as follows: Day 1 Intro to Claims-based Identity & the Windows Identity Foundation WIF introduces important concepts like conversion of security tokens and credentials to claims, claims transformation and claims-based authorization. In this module you will learn the basics of the WIF programming model and how WIF integrates into existing .NET code. Externalizing Authentication for Web Applications WIF includes support for the WS-Federation protocol. This protocol allows separating business and authentication logic into separate (distributed) applications. The authentication part is called identity provider or in more general terms - a security token service. This module looks at this scenario both from an application and identity provider point of view and walks you through the necessary concepts to centralize application login logic both using a standard product like Active Directory Federation Services as well as a custom token service using WIF’s API support. Externalizing Authentication for SOAP Services One big benefit of WIF is that it unifies the security programming model for ASP.NET and WCF. In the spirit of the preceding modules, we will have a look at how WIF integrates into the (SOAP) web service world. You will learn how to separate authentication into a separate service using the WS-Trust protocol and how WIF can simplify the WCF security model and extensibility API. Day 2 Advanced Topics:  Security Token Service Architecture, Delegation and Federation The preceding modules covered the 80/20 cases of WIF in combination with ASP.NET and WCF. In many scenarios this is just the tip of the iceberg. Especially when two business partners decide to federate, you usually have to deal with multiple token services and their implications in application design. Identity delegation is a feature that allows transporting the client identity over a chain of service invocations to make authorization decisions over multiple hops. In addition you will learn about the principal architecture of a STS, how to customize the one that comes with this training course, as well as how to build your own. Outsourcing Authentication:  Windows Azure & the Azure AppFabric Access Control Service Microsoft provides a multi-tenant security token service as part of the Azure platform cloud offering. This is an interesting product because it allows to outsource vital infrastructure services to a managed environment that guarantees uptime and scalability. Another advantage of the Access Control Service is, that it allows easy integration of both the “enterprise” protocols like WS-* as well as “web identities” like LiveID, Google or Facebook into your applications. ACS acts as a protocol bridge in this case where the application developer doesn’t need to implement all these protocols, but simply uses a service to make it happen. Claims & Federation for the Web and Mobile World Also the web & mobile world moves to a token and claims-based model. While the mechanics are almost identical, other protocols and token types are used to achieve better HTTP (REST) and JavaScript integration for in-browser applications and small footprint devices. Also patterns like how to allow third party applications to work with your data without having to disclose your credentials are important concepts in these application types. The nice thing about WIF and its powerful base APIs and abstractions is that it can shield application logic from these details while you can focus on implementing the actual application. HTH

• Free Video Training: ASP.NET MVC 3 Features

  - by ScottGu

  A few weeks ago I blogged about a great ASP.NET MVC 3 video training course from Pluralsight that was made available for free for 48 hours for people to watch.  The feedback from the people that had a chance to watch it was really fantastic.  We also received feedback from people who really wanted to watch it – but unfortunately weren’t able to within the 48 hour window. The good news is that we’ve worked with Pluralsight to make the course available for free again until March 18th.  You can watch any of the course modules for free, through March 18th, on the www.asp.net/mvc website here: The 6 videos in this course are a total of 3 hours and 17 minutes long, and provide a nice overview of the new features introduced with ASP.NET MVC 3 including: Razor, Unobtrusive JavaScript, Richer Validation, ViewBag, Output Caching, Global Action Filters, NuGet, Dependency Injection, and much more.  Scott Allen is the presenter, and the format, video player, and cadence of the course is really excellent. It provides a great way to quickly come up to speed with all of the new features introduced with the new ASP.NET MVC 3 release. Introductory ASP.NET MVC 3 course also coming soon The above course provides a good way for people already familiar with ASP.NET MVC to quickly learn the new features in the V3 release. Pluralsight is also working on a new introductory ASP.NET MVC 3 course series designed for developers who are brand new to ASP.NET MVC, and who want an end to end training curriculum on how to come up to speed with it.  It will cover all of the basics of ASP.NET MVC (including the new Razor view engine), how to use EF code first for data access, using JavaScript/AJAX with MVC, security scenarios with MVC, unit testing applications, deploying applications, and more. I’m excited to pre-announce that we’ll also make this new introductory series free on the www.asp.net/mvc web-site for anyone to watch. I’ll do another blog post linking to it once it is live and available. Hope this helps, Scott

• Optimizing lifestyle and training

  - by Gabe

  I am a college freshman who has recently discovered a passion for computer science. Having had my first lick of formal python training last semester, I have cast aside my previously hedonist way of life and tunneled my sights on becoming the most rounded and proficient programmer I can be. I know that I'm taking strides in the right direction (I've stopped smoking, I've been exercising every day, I've taught myself C++ and OpenGL, and I've begun training in kung-fu and meditation), yet I am still finding myself struggling to achieve satisfactory results. I would like to be able to spend a good 3-4 hours every day burning through textbooks. I have the time cleared and the resources allocated. The problem lies in the logistics-- I have never taken anything seriously before. Recently I've realized that I am clueless when it comes to taking care of myself and gaining control of my mind, and it drastically hinders my productivity. My question is this: How can I learn to manage my time and take care of myself such that I can spend the maximum amount of time every day studying with steady concentration? Personal tricks would be key here: techniques you use to get yourself to sleep, a diet that yields focus, even computer break stretching routines or active reading techniques. Anything you could think of here would be great. I was a low-life in high school and I have the drive to turn my life around, I'm just quite a bit behind in the way of good habits :)

• Gems In The Visual Studio 2010 Training Kit - Introduction to ASP.NET MVC: Learning Labs

  - by Jim Duffy

  Following up on my prior “gems post” is another nugget I found in the Visual Studio 2010 and .NET Framework 4 Training Kit. ASP.NET MVC has established quite a bit of momentum in the ASP.NET development community since it was introduced in early-ish 2009 though I’m sure there are many developers who haven’t had the time or opportunity to find out what it is, not to mention learn how to use it. If you’re one of those “I’ve heard of it but I’m not sure what it really is” developers then I suggest you start your research here. Ok, back to the gem. There are a number of fantastic MVC learning resources out there including the video tutorials on the ASP.NET MVC website. Another learning resource for your journey along the yellow brick road into ASP.NET MVC land are the hands-on learning labs contained in the Visual Studio 2010 and .NET Framework 4 Training Kit. These hands-on exercises walk you through the process of creating the “M”, the “V”s, and the “C”s of ASP.NET MVC and help you gain a solid foothold into the details of creating and understanding ASP.NET MVC applications. Have a day. :-|

• SL3/SL4 - Ado.Net Data Services Error during new DataServiceCollection<T>(queryResponse)

  - by Soulhuntre

  Hey all, I have two functions in a SL project (VS2010) that do almost exactly the same thing, yet one throws an error and the other does not. It seems to be related to the projections, but I am unsure about the best way to resolve. The function that works is... public void LoadAllChunksExpandAll(DataHelperReturnHandler handler, string orderby) { DataServiceCollection<CmsChunk> data = null; DataServiceQuery<CmsChunk> theQuery = _dataservice .CmsChunks .Expand("CmsItemState") .AddQueryOption("$orderby", orderby); theQuery.BeginExecute( delegate(IAsyncResult asyncResult) { _callback_dispatcher.BeginInvoke( () => { try { DataServiceQuery<CmsChunk> query = asyncResult.AsyncState as DataServiceQuery<CmsChunk>; if (query != null) { //create a tracked DataServiceCollection from the result of the asynchronous query. QueryOperationResponse<CmsChunk> queryResponse = query.EndExecute(asyncResult) as QueryOperationResponse<CmsChunk>; data = new DataServiceCollection<CmsChunk>(queryResponse); handler(data); } } catch { handler(data); } } ); }, theQuery ); } This compiles and runs as expected. A very, very similar function (shown below) fails... public void LoadAllPagesExpandAll(DataHelperReturnHandler handler, string orderby) { DataServiceCollection<CmsPage> data = null; DataServiceQuery<CmsPage> theQuery = _dataservice .CmsPages .Expand("CmsChildPages") .Expand("CmsParentPage") .Expand("CmsItemState") .AddQueryOption("$orderby", orderby); theQuery.BeginExecute( delegate(IAsyncResult asyncResult) { _callback_dispatcher.BeginInvoke( () => { try { DataServiceQuery<CmsPage> query = asyncResult.AsyncState as DataServiceQuery<CmsPage>; if (query != null) { //create a tracked DataServiceCollection from the result of the asynchronous query. QueryOperationResponse<CmsPage> queryResponse = query.EndExecute(asyncResult) as QueryOperationResponse<CmsPage>; data = new DataServiceCollection<CmsPage>(queryResponse); handler(data); } } catch { handler(data); } } ); }, theQuery ); } Clearly the issue is the Expand projections that involve a self referencing relationship (pages can contain other pages). This is under SL4 or SL3 using ADONETDataServices SL3 Update CTP3. I am open to any work around or pointers to goo information, a Google search for the error results in two hits, neither particularly helpful that I can decipher. The short error is "An item could not be added to the collection.

• 3rd party data - Store in Data Warehouse or Primary database?

  - by brydgesk

  This is mostly a data warehouse philosophy question. My project involves an Oracle forms application, and a Teradata Data Warehouse for reporting and ad-hoc purposes. In addition to the primary data created by the users of our application, we also require data from various other sources. Currently, this 3rd party data comes via FTPd flat files directly to our Data Warehouse. To access the data, our users must use a series of custom BusinessObjects reports. My question is, would it make more sense for this data to be sent to our source Oracle system instead? Is it ever appropriate for a Data Warehouse to be the point of origin for users to access raw data? In short, is it more important that the operational database contain only the data created by your project, or that the data warehouse remain dedicated solely to reporting and analysis?

• Starting to construct a data access layer. Things to consider?

  - by Phil

  Our organisation uses inline sql. We have been tasked with providing a suitable data access layer and are weighing up the pro's and cons of which way to go... Datasets ADO.net Linq Entity framework Subsonic Other? Some tutorials and articles I have been using for reference: http://www.asp.net/(S(pdfrohu0ajmwt445fanvj2r3))/learn/data-access/tutorial-01-vb.aspx http://www.simple-talk.com/dotnet/.net-framework/designing-a-data-access-layer-in-linq-to-sql/ http://msdn.microsoft.com/en-us/magazine/cc188750.aspx http://msdn.microsoft.com/en-us/library/aa697427(VS.80).aspx http://www.subsonicproject.com/ I'm extremely torn, and finding it very difficult to make a decision on which way to go. Our site is a series of 2 internal portals and a public web site. We are using vs2008 sp1 and framework version 3.5. Please can you give me advise on what factors to consider and any pro's and cons you have faced with your data access layer. Thanks.

• Using Core Data Concurrently and Reliably

  - by John Topley

  I'm building my first iOS app, which in theory should be pretty straightforward but I'm having difficulty making it sufficiently bulletproof for me to feel confident submitting it to the App Store. Briefly, the main screen has a table view, upon selecting a row it segues to another table view that displays information relevant for the selected row in a master-detail fashion. The underlying data is retrieved as JSON data from a web service once a day and then cached in a Core Data store. The data previous to that day is deleted to stop the SQLite database file from growing indefinitely. All data persistence operations are performed using Core Data, with an NSFetchedResultsController underpinning the detail table view. The problem I am seeing is that if you switch quickly between the master and detail screens several times whilst fresh data is being retrieved, parsed and saved, the app freezes or crashes completely. There seems to be some sort of race condition, maybe due to Core Data importing data in the background whilst the main thread is trying to perform a fetch, but I'm speculating. I've had trouble capturing any meaningful crash information, usually it's a SIGSEGV deep in the Core Data stack. The table below shows the actual order of events that happen when the detail table view controller is loaded: Main Thread Background Thread viewDidLoad Get JSON data (using AFNetworking) Create child NSManagedObjectContext (MOC) Parse JSON data Insert managed objects in child MOC Save child MOC Post import completion notification Receive import completion notification Save parent MOC Perform fetch and reload table view Delete old managed objects in child MOC Save child MOC Post deletion completion notification Receive deletion completion notification Save parent MOC Once the AFNetworking completion block is triggered when the JSON data has arrived, a nested NSManagedObjectContext is created and passed to an "importer" object that parses the JSON data and saves the objects to the Core Data store. The importer executes using the new performBlock method introduced in iOS 5: NSManagedObjectContext *child = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType]; [child setParentContext:self.managedObjectContext]; [child performBlock:^{ // Create importer instance, passing it the child MOC... }]; The importer object observes its own MOC's NSManagedObjectContextDidSaveNotification and then posts its own notification which is observed by the detail table view controller. When this notification is posted the table view controller performs a save on its own (parent) MOC. I use the same basic pattern with a "deleter" object for deleting the old data after the new data for the day has been imported. This occurs asynchronously after the new data has been fetched by the fetched results controller and the detail table view has been reloaded. One thing I am not doing is observing any merge notifications or locking any of the managed object contexts or the persistent store coordinator. Is this something I should be doing? I'm a bit unsure how to architect this all correctly so would appreciate any advice.

• Used HDD/ran DiskSmartView/40,000 Power-on-hours?? should i trust it w/ my data, or take it back and bitch?

  - by David Lindsay

  I just bought a used hard drive from a University Surplus Store. Decided to run DiskSmartView to make sure it wasn't ready to fail. 40,000 power-on-hours I don't know if I feel like trusting my data to something that used. I really dont know if thats unreasonably old, but when i compare it to the POH reading i get when testing my other hdds its more than 3x older (my others have 2110 hours, 6150 hours, etc.. It's a Western Digital, so that gives me a little bit of hope(WDC WD4000KD-00NAB0). I could sure use someone else's opinion here. Thanks, DAVE

• SSAS Maestro Training in July 2012 #ssasmaestro #ssas

  - by Marco Russo (SQLBI)

  A few hours ago Chris Webb blogged about SSAS Maestro and I’d like to propagate the news, adding also some background info. SSAS Maestro is the premier certification on Analysis Services that selects the best experts in Analysis Services around the world. In 2011 Microsoft organized two rounds of training/exams for SSAS Maestros and up to now only 11 people from the first wave have been announced – around 10% of attendees of the course! In the next few days the new Maestros from the second round should be announced and this long process is caused by many factors that I’m going to explain. First, the course is just a step in the process. Before the course you receive a list of topics to study, including the slides of the course. During the course, students receive a lot of information that might not have been included in the slides and the best part of the course is class interaction. Students are expected to bring their experience to the table and comparing case studies, experiences and having long debates is an important part of the learning process. And it is also a part of the evaluation: good questions might be also more important than good answers! Finally, after the course, students have their homework and this may require one or two months to be completed. After that, a long (very long) evaluation process begins, taking into account homework, labs, participation… And for this reason the final evaluation may arrive months later after the course. We are going to improve and shorten this process with the next courses. The first wave of SSAS Maestro had been made by invitation only and now the program is opening, requiring a fee to participate in order to cover the cost of preparation, training and exam. The number of attendees will be limited and candidates will have to send their CV in order to be admitted to the course. Only experienced Analysis Services developers will be able to participate to this challenging program. So why you should do that? Well, only 10% of students passed the exam until now. So if you need 100% guarantee to pass the exam, you need to study a lot, before, during and after the course. But the course by itself is a precious opportunity to share experience, create networking and learn mission-critical enterprise-level best practices that it’s hard to find written on books. Oh, well, many existing white papers are a required reading *before* the course! The course is now 5 days long, and every day can be *very* long. We’ll have lectures and discussions in the morning and labs in the afternoon/evening. Plus some more lectures in one or two afternoons. A heavy part of the course is about performance optimization, capacity planning, monitoring. This edition will introduce also Tabular models, and don’t expect something you might find in the SSAS Tabular Workshop – only performance, scalability monitoring and optimization will be covered, knowing Analysis Services is a requirement just to be accepted! I and Chris Webb will be the teachers for this edition. The course is expensive. Applying for SSAS Maestro will cost around 7000€ plus taxes (reduced to 5000€ for students of a previous SSAS Maestro edition). And you will be locked in a training room for the large part of the week. So why you should do that? Well, as I said, this is a challenging course. You will not find the time to check your email – the content is just too much interesting to think you can be distracted by something else. Another good reason is that this course will take place in Italy. Well, the course will take place in the brand new Microsoft Innovation Campus, but in general we’ll be able to provide you hints to get great food and, if you are willing to attach one week-end to your trip, there are plenty of places to visit (and I’m not talking about the classic Rome-Florence-Venice) – you might really need to relax after such a week! Finally, the marking process after the course will be faster – we’d like to complete the evaluation within three months after the course, considering that 1-2 months might be required to complete the homework. If at this point you are not scared: registration will open in mid-April, but you can already write to [email protected] sending your CV/resume and a short description of your level of SSAS knowledge and experience. The selection process will start early and you may want to put your admission form on top of the FIFO queue!

• Windows Azure Recipe: Big Data

  - by Clint Edmonson

  As the name implies, what we’re talking about here is the explosion of electronic data that comes from huge volumes of transactions, devices, and sensors being captured by businesses today. This data often comes in unstructured formats and/or too fast for us to effectively process in real time. Collectively, we call these the 4 big data V’s: Volume, Velocity, Variety, and Variability. These qualities make this type of data best managed by NoSQL systems like Hadoop, rather than by conventional Relational Database Management System (RDBMS). We know that there are patterns hidden inside this data that might provide competitive insight into market trends.  The key is knowing when and how to leverage these “No SQL” tools combined with traditional business such as SQL-based relational databases and warehouses and other business intelligence tools. Drivers Petabyte scale data collection and storage Business intelligence and insight Solution The sketch below shows one of many big data solutions using Hadoop’s unique highly scalable storage and parallel processing capabilities combined with Microsoft Office’s Business Intelligence Components to access the data in the cluster. Ingredients Hadoop – this big data industry heavyweight provides both large scale data storage infrastructure and a highly parallelized map-reduce processing engine to crunch through the data efficiently. Here are the key pieces of the environment: Pig - a platform for analyzing large data sets that consists of a high-level language for expressing data analysis programs, coupled with infrastructure for evaluating these programs. Mahout - a machine learning library with algorithms for clustering, classification and batch based collaborative filtering that are implemented on top of Apache Hadoop using the map/reduce paradigm. Hive - data warehouse software built on top of Apache Hadoop that facilitates querying and managing large datasets residing in distributed storage. Directly accessible to Microsoft Office and other consumers via add-ins and the Hive ODBC data driver. Pegasus - a Peta-scale graph mining system that runs in parallel, distributed manner on top of Hadoop and that provides algorithms for important graph mining tasks such as Degree, PageRank, Random Walk with Restart (RWR), Radius, and Connected Components. Sqoop - a tool designed for efficiently transferring bulk data between Apache Hadoop and structured data stores such as relational databases. Flume - a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large log data amounts to HDFS. Database – directly accessible to Hadoop via the Sqoop based Microsoft SQL Server Connector for Apache Hadoop, data can be efficiently transferred to traditional relational data stores for replication, reporting, or other needs. Reporting – provides easily consumable reporting when combined with a database being fed from the Hadoop environment. Training These links point to online Windows Azure training labs where you can learn more about the individual ingredients described above. Hadoop Learning Resources (20+ tutorials and labs) Huge collection of resources for learning about all aspects of Apache Hadoop-based development on Windows Azure and the Hadoop and Windows Azure Ecosystems SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

• What is the architectural name for the set of data that enables UI choices?

  - by Richard Collette

  I have separate service methods that fetch business object data and the data for UI selection input such as radio buttons, check-boxes, combo-boxes, etc. I want to name my service methods that fetch the selection data appropriately. I am assuming that Model and ViewModel would not be part of the name because the selection data is but a portion of the Model or ViewModel. What might this set of data be named such that I can name my service method?
