TGIF!! I am super busy right now designing a multi-CPU/multi-threaded Parallel Calculation Engine and diving into the science of Parallel Computing. I'll have some links when I get a chance. Windows Workflow Tomas talks about Silver , the integration of WF + WCF. The marriage is sorely needed because, as I have posted here , the current situation well, sucks. Silver uses Queues and bypasses EDS completely, which is what anyone needs to do to have any real success of communication into Workflows. Because we could not use Orcas here, we actually implemented our own version of the mechanism to avoid the hell that is EDS. Jon Flanders , the guy that helped me with the above, also worked on the PageFlow Sample that has been updated to V1.1 Even more interesting is that he has working on this project for hosting Workflows inside of BizTalk. This is very interesting as developing your own host is so not trivial, but I totally challenge Paul's assertion that " No BizTalk Experience Required ." Architecture Steve Jones has a post YAGNI, Requirements and why scaling isn't always important that I totally agree with and is in-line with what I try to do as an " Agile Architect ": "Split information exchange from the business services, and worry about the scaling that is appropriate for your information exchange. Don't worry about technical purity and some "wonder" architectural approach. Don't over engineer because if you do X (or R) then it will scale to 100,000 users, but your requirements say "6". Software Design/Agile/XP/Design Patterns/CAB Number 11 for Jeremy in his continuing excellent series on UI Design Patterns in Build your own CAB #11 - Event Aggregator Jeremy has another big AMEN post for me in his Design for Testability , which really goes with my Writing Maintainable Code post, "" Done, done, done " isn't just writing code. It's writing code and verifying that that code works correctly. Read More...

Sitting here on Saturday morning with a nice cup of Kona coffee. There just is no better coffee in the world. Strong but deceivingly smooth. I really miss our former annual trips to the Big Island that we used to take with my Father-In-Law and family before he got ill. We used to go up in the hills and buy direct from the growers. Umm, nothing better. The coffee may actually help me get over my funk morning as there is now a lot going on my personal life but you know you never get to blog what really matters Agile/Extreme Programming/Tools While Steve was off having a baby , I went back into the team pairing full time for this Iteration rather than doing do the advance work on Workflow and stuff. It felt really good and of course it was a challenge for me, as many of the particulars of the system have changed since I last paired and I had to actually relies on my pair more. What floored me, even though it shouldn't at this point, is just how good this team has gotten. Every single person on the team could explain any place in the code at any time and we were able to evolve the design and code together. It still blows me away the power of pair programming BTW, we are working on our THIRD release of our Collateral Management tools and architecture to at least two Top 50 Banks! Ayende has released Rhino Mocks 3.0 , the premier Mocking solution on .NET IMHO He was also on .NET Rocks talking about NHibernate and Rhino Mocks Since he still had time after the last two somehow, he also put out an hour long screen cast about Rhino Mocks Jeremy is Code Complete on Structure Map 2.0 Financial and Banking Mike Walker announces the OBA Reference Application Pack for Loan Origination Systems (OR-Loss ). This is a lot of great stuff here Mike is also doing a Financial Services Unwrapped IV Webcast Workflow Paul Andrews blogs about the 3rd performance paper released for WF Sylvain blogs that K2 BlackPearl Beta 1 TR2 is available.

Smart Clients/Orcas I am extremely pleased to see the .NET Framework (and Microsoft) finally gain the offline sync services that I have been talking about for quite a few years in my work at Groove and Adesso . You will be able to do synchronization from WinForms and WPF apps that you could do from Groove apps (in my case WinForms) 4 years ago and Adesso 2-3 years ago now.

Thank God, its Friday. Even after a full 32 ounces of strong Starbucks coffee, I still fell asleep on the train on the way in. Entity Framework/OR/M/LINQ The excellent Entity Framework discussions continue with Scott Bellware's fine Entity Framework Challenges Architecture One of my core principles of Agile Architecture that I will talk about in Monteal next month is that of Lighweight Modeling. Core to that, is what Scott Bellware said, That's "Model-Driven", not "Diagram Driven ." Like Scott says, I also put my model into the domain and evolving that model. I too don't find much use for diagrams, particuarly the waste of time Whitehorse ones or worse yet the Rational Rose ones. But, as Jeremy noted from his discussion with me , I *do* find the use of a very small subset of UML used rather precisely in drawing quick, non-durable model diagrams on the board. In fact, Jim Shore and I taught our team to do it in any part of the code base at any time. Harry channeling Nick , "Nick Malik on enterprise architecture : "Enterprise Architecture is not about 'building solutions right'. Enterprise Architecture is about 'building the right solutions'. Agile/Good Software Design Jeremy on the DRY principle and the Wormhole Anti-Pattern He also points to the great piece Top ten things ten years of professional software development has taught me . Agreed with all of it Jonathan has a niece piece that I vigorously nodded my head in agreement with, Pair Programming improves your Communication Skills .NET/CLR Scott Hanselman - A Better Way for Click Once and Firefox . Yes!! Misc I was ROTFL when I read Lazycoder's rant , "Save me from having to type more angle brackets. Please. I’m tired of $#@$@ angle brackets. My “,” and “.” keys are worn to a nub. My shift key is floppy and has no spring left.No more angle-bracket based UI. EVER." Technorati Tags: .NET , Orcas , Entity Framework , Read More...

I have been working with the Office Live Services Beta for some months now. They just went live with my site over the weekend (although I still have to work on the domain name transfer) and it looks pretty good! I have a new Header and Home Page design. I have added my How-To STS/Window Authentication with ADAM/AD, Roles in AzMan with WCF to the refurbished WCF page . I added a new Domain Driven Design page under Software Engineering . My Presentations, as always are here . Hey, what else am I going to do while I am waiting for my flight? I would like and appreciate any and all feedback as comments here. What's good? What's bad? Knowing my blog and its subjects, what would you like to see?

Yup, I'm still stuck in Seattle and I still feel like crap. Tomas just went off to the airport and I feel like the last MVP left in Seattle. Just want to get out of here and home but can't do that until tomorrow night. Lots of stuff stored up Entity Framework/ADO.NET 3/ORM/ASP.NET/MonoRail I consider my (and all the Code Better guys) biggest contribution to the whole Summit has been our conversations with the Microsoft Data Team on Linq for Entities . I would like to thank the Microsoft guys for being so open to feedback and understanding us In the meantime, Ayende went and did LINQ for NHibernate in his spare Time; does this man ever sleep???? Actually the second proudest moment came some of us CB bloggers with the special meeting with Scott Guthrie on how to make ASP.Net better support MVC much like Rails and MonoRail. My dissatisfaction with ASP.NET is well known and the reasons are expressed well by Ayende here on the leaky abstractions with WebForms and Jeremy Miller here . I expressed many times on my blog that I would just as soon go to Ruby on Rails if I had to do any Web stuff today. Several of the CB bloggers let me know about the goodness that is MonoRail. It's really awesome to see ScottGu have an MVC framework in the works as Jeffery talks about here Inheritance in the Entity Framework is the latest from the Data Team They also updated the 101 LINQ Samples that were included in the March CTP have now been updated to include the 101 LINQ to Entities Samples. To check out the newest samples download from here . Software Architecture/WCF/SOA Nice discussion from Harry on answering Dr. Nick's questions on SSB/WCF The Feb 2007 release of both the GAT and GAX have been released with Vista support but Harry has noted that you have to re-install all your guidance packages which is not so good Christian Weyer has some great slide decks from DevWeek 2007 Matias has an awesome post, " The holy grail of Enterprise SOA security " about SOA Enterprise Security using WCF Read More...

Still real tired from my Oklahoma trip , partying with Raymond sure is exhausting-). Agile/Development Tools On my short list for some time now, is to switch from NUnit to the definitely superior MbUnit. My friend Andrew has done some great work with this tool and he has a new release out with the beta 1 release of MbUnit 2.4. New features in this drop. I really need to switch and get my team to switch over. It's just been an inertia thing with NUNit as I knew all along MbUnit was better Testing private methods for .NET 2.0 rom Ben Hall. Database rollback support for .NET 2.0 from Cathal Connolly and Todd Menier. NUnit style explicit support from Graham Hey. Speaking of NUnit, they also have a new release, NUnit 2.4 Release Candidate (2.4.0). The Release Notes are here and include some nice features: A new syntax and internal architecture for Asserts is being introduced in this release, based on the notion of constraints found in JMock and NMock. The Assert.That method is used to make an assertion based on a constraint Assert.That( actual, constraint, message, args ); Assert.That( actual, constraint, message ); Assert.That( actual, constraint ); The constraint argument may be specified directly using one of the built-in constraint classes or a user-defined class. It may also be specified using one of the syntax helpers provided as static methods of the Is class, such as Is.Null Is.Empty Is.EqualTo( object ) Is.CollectionContaining( object ) Is.SubsetOf( collection ) SCSF is one of the most visible Microsoft projects being done in an Agile way. They are crazy as us doing one week Iterations. Blaine has some reflections on Iteration 3 . CB brother, Jeremy asks what OSS tools are you using in development? As I answered there, they include: NUnit CruiseControl.Net FitNesseDotNet RhinoMocks Subversion TortoiseSVN Ankh Wiki Speaking of tools. my good buddy Tomas (see you next week!) has a nice list of Text Editors One of the things Raymond and I discussed in Oklahoma was Read More...

In a post on January 25th , I said, "I posted yesterday that we had shipped our Enterprise Collateral Management solution based on our new architecture. As I said, we still have a lot more to do ." I provided a concise list of the methodologies, technologies and tools that we used in our 14 month cycle. To update where we are now, it will be necessary for me to give a little more context. First, when I mention "our company", we are actually a Division exclusively devoted to Collateral Management. This division, in turn is part of a much larger worldwide company that has at least 6 more financial sector products dealing with other aspects of managing risk. That company then, in turn is part of a huge Ratings company. The rest of the products are (mostly) integrated into one suite that we sell. Ours is not. One reason is that the various products have been organized into self-contained product groups. That means that we had our own development, marketing, sales, product and management for just Collateral Management. Five or six weeks ago, our company went through a rather large reorganization that aligned things by a global R&D, global Marketing, etc. I think this is an extremely good thing. Our product is now "owned" by R&D which also owns all the other products that are part of the suite and otherwise and we are detached from product so we can focus on development. We can also look at integrating into the suite and bi-directional learning. One consequence of this is now instead of my boss reporting to a VP of Collateral Management, he reports to a Senior Director in R&D who owns a product out of our large offices in Manhattan. The cool thing is that Josh Madden is a 20 year+ veteran developer/architect like me who has done great things in the Financial area for companies like Reuters. He gets development. The other cool thing is that his other product group also uses a lot of Agile techniques and greatly appreciates our total XP environment. One more thing: Read More...

Data/ADO.NET Orcas Two from the ADO.NET team: Entity Client and Nulls - LINQ to DataSets Part 3 Software Architecture/SOA/CAB Udi answers, Can or should SOA be implemented without Web Services? David Chappell on The Three Faces of SOA Eric Newcomer: WS-* vs. REST is not the question Another architect with a chronicle of How CAN and TDD helps doing better designs WCF/CardSpace Richard Turner gives an insightful report on RSA2007 especially on the "demo showed Wachovia 's website running on Corillian 's online banking platform using Arcot Systems ' security engine to generate managed cards and process token requests." Corrillian and Wachovia's work will be important for all of this in this sector as more and more backs embrace CardSpace and Identity management. We are seeing a lot of movement in this area.

Family morning at the Gentiles means the whole family watching Radiohead from 1994 while waiting for the Starbucks to come... Software Development Ayende points to this great list Nine Things Developers Want More Than Money and asks what excites you as a developer? As I said in a Retrospective last night, its not about money for me or just a job (expressed as "Build Something That Matters"). If I can't have the passion for my project, my career as a Software Architect, taking the responsibility for my own career, than I need to find something else to do because this is far from the least stressful job out there. You had better be in it because you love it and love to create and ship stuff that delights customers. Otherwise I can go weave baskets out in New Mexico... Data/OR/M/Software Architecture Jeff Palermo notes that we'll see Microsoft's OR/M soon and I can't help thinking BFD and its about time. After years of misleading developers that Stored Procs and database-driven architectures and apps were the only way , is too late? Many of us who have been doing this for a while and come out of other environments are already way ahead using Wilson OR/M, NHibernate, LBLgen and others.

We have a new addition to our house - a 60 pound 2-year old English Bulldog! Agile/TDD The big news of the day is my good friend Jamie Cansdale's TestDriven.Net - Check here for download . To say this product is indispensable is an understatement. I sit inside Visual Studio all day writing NUnit tests and the right click Run Tests has saved me thousands of key strokes. The right-click "Test With Debugger" is lifesaver in the very few times I use the debugger. Jamie has got some really cool new features like Repeat Test and Reflector Integration! I don't know of anyone personally who already doesn't have this tool but you owe to yourself to get it if you are one of the few without it. BTW, I have had the benefit of having Jamie's help and support many times during IM sessions and he is a real asset to the community . He has given thousands of hours so I support him fully in trying to cover support costs by having his Professional and Enterprise Editions. I highly encourage you if it you are using it in your company to buy Professional and Enterprise licenses. Architecture/SOA Nick Malik writes well on the benefits of Enterprise Architecture "Rocking Your World" Eric Newcomber on Incremental Approach to SOA Infrastructure Tomas points to a bunch of discussions on WCF and Duplex Channels and support for long running transactions. Before, I get into that, I see WCF Duplex Channels as a real useful feature for doing certain types of architectures and applications. For instance, Steve and myself have discussed it many times for a product we want to have in our banking/financial environment to allow direct inter-bank communications. This would be very different than the SWIFT type support. But the concern that always stops us is the security one and that not many banks (or customers) would want another firewall port opened up for the return channel. In that same post, but I needed to call it out separate, Tomas rightfully says, "I'd say SSSB is a good match only as long as Read More...

Now that I got my Feed Demon back, I actually have some stuff in the queue that is not so "new" but perhaps still "notable." Architecture/CAB/Smart Client Oldie but goodie: Eugenio has compiled a list of CAB and Smart Client Software Factory Resources You can also see my mini-tutorial combined with an Agile sense with CAB Smart Clients in an Agile World Part 1 , and Part 2 Microsoft Software Factory Architect Jack Greenfield on Ad-Hoc and Systematic Reuse where he differentiates the two and points out that the "i n the software factories book , we explain that systematic reuse is effective, but ad hoc reuse is not." Indigo/WCF/SOA/BPM/BPEL/Workflow More goodness from Tomas with IServiceBehavior, IDispatchMessageInspector, and Endpoints A pair from the master, David Chappell, with Why BEPL is Like Bytecode , and Standardizing the Right Thing: BPMN or BPEL? Avoiding OneWay Deadlocks from Nicholas Allen Data/SQL Server CTP6 of Data Dude (i.e. VSTS for Database Pros) is out . Cameron has the scoop on the new features. Other/Tools IE7 has made it out of beta and is released The very useful CodeSmith is out in a public Beta 4.2 Agile Martin Fowler calls it the ImprovementRavine Pattern: " If you care about what you do, you care about getting better at it. This involves reflecting about how you do things, and trying out new techniques to see if they make you better. Even if other people recommend new techniques, the only way you know if they work for you is by trying them out yourself and seeing if they improve your performance.The trouble is that improvement, particularly with new techniques isn't linear. Often there is a ravine that opens up when you try a new strategy ."
