I Hate Global.asax

One of the things I’ve always loved about ASP.NET is how easily extensible it is. Back in 2000, I had a customer that wanted to “skin” their website using XML and XSLT – an approach Martin Fowler later called Transform View. We were working with classic ASP at the time, so the solution we ended up with was kind of ugly. But I was able to implement this approach in ASP.NET in a few hundred lines of code, which I wrote up in an MSDN article published back in 2003. In the conclusion of that article, I wrote the following:

Using ASP.NET is kind of like having your mind read. If you ever look at a site and think "I need something different," you'll most likely find that the ASP.NET architects have considered that need and provided a mechanism for you to hook in your custom functionality. In this case, I've bypassed the built-in Web Forms and Web Services support to build an entire engine that services Web requests in a unique way.

Nearly ten years later, I finally ran into a situation where ASP.NET failed to read my mind and doesn’t provide a mechanism to hook in custom functionality: Global.asax.

I always thought of global.asax as an obsolete construct primarily intended to ease migration from classic ASP. After all, ASP.NET has first class support for customizing request handling at various points throughout the execution pipeline via IHttpModule. Handling those events in global.asax always felt vaguely hacky to me.

However, what I didn’t realize is that there are some events that can only be handled via global.asax (or its code behind). In particular, Application_Start/End and Session_Start/End can only be handled in global.asax. Worse, these aren’t true events. For reasons I’m sure made sense at the time but that I don’t understand, the HttpApplicationFactory discovers these methods via reflection rather than by an interface or other more typical mechanism. You can check it out for yourself with Reflector or the Reference Source – look for the method with the wonderful name ReflectOnMethodInfoIfItLooksLikeEventHandler. No, I’m not making that up.

The reason I suddenly care about global.asax is because Application_Start is where ASP.NET MVC apps configure their route table. But if you want to access the Application_Start method in a dynamic language like IronPython, you’re pretty much out of luck. The only way to receive the Application_Start pseudo-event is via a custom HttpApplication class. But you can’t implement your custom HttpApplication in a dynamically typed language like IronPython since it finds the Application_Start method via Reflection. Ugh.

If someone can explain to me why ASP.NET uses reflection to fire the Application_Start event, I’d love to understand why it works this way. Even better - I’d love to see this fixed in some future version of ASP.NET. You come the only way to configure a custom HttpApplication class is to specify it via global.asax? Wouldn’t it make sense to specify it in web.config instead?

In order to support Application_Start for dynamic languages you basically have two choices:

1. Build a custom HttpApplication class in C# and reference it in global.asax. This is kind of the approach used by Jimmy’s ironrubymvc project. He’s got a RubyMvcApplication which he inherits his GlobalApplication from. Given that GlobalApplication is empty, I think he could remove his global.asax.cs file and just reference RubyMvcApplication from global.asax directly.
2. Build custom Application_Start/End-like events out of IHttpModule Init and Dispose. You can have multiple IHttpModule instances in a given web app, so you’d need to make sure you ran fired Start and End only once. This is the approach taken by the ASP.NET Dynamic Language Support. [1]

So here’s the question Iron Language Fans: Which of these approaches is better? I lean towards Option #1, since it traps exactly the correct event though it does require a global.asax file to be hanging around (kind of like how the ASP.NET MVC template has a blank default.aspx file “to ensure that ASP.NET MVC is activated by IIS when a user makes a "/" request”). But I’m curious what the Iron Language Community at large thinks. Feel free to leave me a comment or drop me an email with your thoughts.

[1] FYI, I’m working on getting the code for ASP.NET Dynamic Language Support released. In the meantime, you can verify what I’m saying via Reflector.

Webdev Script and KillWebDevServer

I was updating my webdev powershell script today. I wanted to add support for a -browser switch that would automatically launch a browser window the way chiron from the Silverlight Dynamic Languages SDK. does. I also set the script to serve up the current directory by default. I posted the new version up on my SkyDrive.

While I was working on the script, I thought about how one might shutdown the WebDev server from the command line. That turned out to be much harder. Basically, you have to look thru all the top level windows for one that has "ASP.NET Development Server" in the window text, then you send that window two messages - WM_QUERYENDSESSION and WM_QUIT. Not sure why the WebDev server uses WM_QUERYENDSESSION to shut down it's tray icon, but if you look at WebDev.WebServer.exe in Reflector, you'll see the tray icon form overrides WinProc in order to look for message 0x11, i.e. WM_QUERYENDSESSION.

I threw together a quick little C# console app to shutdown the WebDev server and stuck it up on my SkyDrive as well. Source code is up there too. I had to use a bunch of P/Invokes to make it work, or I would have written it in Powershell or IronPython.

Enjoy.

Afternoon Coffee 174

You know, this gets pretty long when I go a week between morning coffee posts.

Dynamic Language Stuff

• There's a new version of the DLR Hosting spec. One of the biggest changes is the removal of DLR's pre-canned knowledge of IPy and IRuby. Now, you use app.config to specify DLR languages and map them to extensions. Sesh has the details and a sample. If you only care about hosting IPy, you can use our language specific hosting API which doesn't require app.config.
• Jimmy pushed out a new version of the Silverlight Dynamic Languages SDK. He's on the lookout for a better name, one of his commenters suggested "SilverWhisper Kit".
• Srivatsn shows how to pass Python keyword arguments to a C# method using ParamDictionaryAttribute, similar to how C# supports the params keyword via the ParamArrayAttribute. Unfortunately, there's no syntactic sugar for calling param dictionary methods from C#. I wonder, do most people like or dislike the idea of language level support for keyword arguments in C#? I'm guessing most would be against, though I think it's a cool idea.
• Maybe it's me, but I've noticed an uptick in twitter posts containing "ironpython" of late. For example, via Summize I discovered Joseph Jude's blog finally{} where he has posted a time tracking tool he built in IPy as well as his initial IPy learnings.
• Michael Foord, as usual, has been generating quite a bit of good IPy content. He did a tutorial on IPy at PyCon UK,  his book is almost done, he has some interesting thoughts on dynamic language performance and even admits that he likes C#, though not as much as he likes Python.
• Vernon Cole announced that the adodbapi project now supports IronPython 2.0 as well as CPython. This library is a DB-API 2.0 compliant interface for any database that support ADO (note, that's native ADO not ADO.NET). I love to see Python projects with explicit support for IPy.
• My boss - who apparently will be called "Rem" from now on in the office - saves you "gazillions" by explaining non-positional negotiating strategy and draws the comparison to agile software development. Not exactly related to dynamic languages, but I'd like to see him further explore the relationship super-optimal, non-positional, significantly-hyphenated negotiation and software design. (OK, I made up "significantly-hyphenated")

Other Stuff

• Don Syme blogs about an update to the F# CTP, a mere week after the original release. One week? That's more often than even IPy releases. I can't wait to see what they ship in next week's release! :) Seriously, I hope they can keep the release sprints short, but every week would be a bit crazy!
• Speaking of F#, Matt Podwysocki updates FsTest for the F# CTP and posts about Extension Everything in F#. Unlike C#, which only supports extension methods, F# also supports extensions properties, static methods and events, though like Matt I can't think of a good use for extension events.
• Still speaking about F#, Andrew Kennedy has a three part series on the new units of measure feature of F#. If you were going to use F# to build the physics engine of a game, I would suspect UoM would be extremely useful. (via Don Syme)
• Oh look, Chris Smith built an F# version of artillery game that uses Units of Measure for the physics code. I'll bet UoM was extremely useful. :)
• Talking about Live Mesh at TechEd Australia - where much to my surprise frankly they were demoing Live Mesh Apps - I pointed out to Scott Hanselman that Mesh is running an embedded CoreCLR (aka the same CLR from Silverlight 2). Scott went poking around and posted what he discovered. Looking forward to finding out what he digs up on using CoreCLR outside the browser.
• Speaking of Scott, I need to set up a family video conference solution like Scott's before my next trip.
• Congrats to Glenn Block and the MEF team for their initial CodePlex source drop! I've been hearing about this possibility since Glenn joined the team, so I'm really excited to see it happen. I need to take a look at it in detail (in my copious spare time) because I want to find out how to make it work with IPy.
• Bart de Smet has a whole series (starting here) on Dynamic Expression Trees. However, given that he specifically writes "This blog series is not about DLR itself" makes it seem pretty conceptual to me. Why not talk about DLR expression trees instead Bart?
• I'm sure you noticed ASP.NET MVC preview 5 dropped last week. I really liked Brad Wilson's discussion of the new view engine design.
• Tomas Restrepo has started publishing his source code on GitHub. Personally, I haven't published any source code lately but I am using Git for all of my non IPy core work (which is stored in TFS). Like Tomas, I'm still getting the hang of Git but I'm really digging it's speed, it's branching and the fact that there's zero infrastructure requirements. SVN provides the lightweight svnserve, but Git is even lighter weight than that.
• I liked Steve Yegge's post on typing. I am a touch typer, but I doubt I type 70 words a minutes. I do know where the number keys are without looking though, so I guess that's pretty good. I remember seeing Chris Anderson demo Avalon WPF long before it was public and being impressed at how fast he could type.

Five Minutes Past Noon Coffee 170

• Ben Hall announces IronEditor, a simple dev tool for IronPython and IronRuby. Pretty nice, though fairly simplistic (as Ben readily admits). For example, it doesn't have an interactive mode, only the ability to execute scripts and direct the output to IronEditor's output window. However, it is a good start and I'm sure it'll just get better. One thing he's apparently considering is a Silverlight version. (via Michael Foord)
• Speaking of "Iron" tools, Sapphire Steel have had an IronRuby version (in alpha) of their Ruby in Steel product for several months now. I wonder if John's had a chance to play with it.
• Speaking of John, the ASP.NET MVC / IronRuby prototype he talked about @ TechEd is now available on ASP.NET MVC Preview 4 via Phil Haack.
• Ted Neward has an article exploring the IronPython VS Integration sample that ships in the VS SDK. As I mentioned the other day, we're starting working on a production quality implementation of VS Integration for IPy.
• Ophir Kra-Oz (aka Evil Fish) blogs Python for Executives. I like his "Risk, Recruiting, Performance and Maturity" model - four boxes, perfect for keeping an executive's attention! :) Plus Ophir has some nice things to say about IronPython. (via Michael Foord)
• Ronnie Maor blogs an extension method for PythonEngine to make Eval simpler. I especially like how he uses string format syntax so you can dynamically generate the code to eval. I wonder what this would look like in IPy 2.0 with DLR Hosting API. (via IronPython URLs)
• Speaking of DLR Hosting, Seshadri has another great DLR hosting post, this time hosting IPy inside of VS08 so you can script VS08 events (document saved, window created, etc) with Python.
• Justin Etheredge has a bunch of IronRuby posts - Getting IronRuby Up and Running, Running Applications in IronRuby, Learning Ruby via IronRuby and C# Part 1. (via Sam Gentile)
• Don Syme links to several F# related posts by Ray Vernagus, though he's apparently also experimenting with IronRuby. I'm really interested in his Purely Functional Data Structures port to F#.
• Speaking of F#, Brian has a teaser screenshot of F# upcoming CTP. However, he chooses the New Item dialog to tease, which looks pretty much like the current new item dialog (the new one does have fewer F# templates). However, if you look in the Solution Explorer, you'll notice a real "References" node. No more #I/#R! Yeah!
• The interactive graphic in Kevin Kelly's One Machine article is fascinating. It really highlights that the vast vast vast majority of power, storage, CPU cycles and RAM come from personal computers on the edge. Even in bandwidth, where PC's still have the highest share but it looks to be around 1/3rd, the aggregate of all edge devices (PCs, mobile phones, PDAs, etc.) still dominates the data centers.

Morning Coffee 169

• Check out the crowd for a the Washington Capitals developmental camp scrimmage last week (My parents are in their somewhere). Standing room only in the practice facility to watch a bunch of kids, most of whom won't ever make it to the NHL, in July. If you think Washington can't be a hockey town, you are sorely mistaken.
• Speaking of the Caps, they are establishing a "spirit squad"? Is that really necessary? (short answer: no). Peerless' take is hilarious.
• Seshadri Vijayaraghavan is a tester on the DLR team and he's been writing quite a bit about the DLR hosting API. He's got a series of posts about hosting, invoking and redirecting output from IronPython in a C# application.
• I haven't seen an official announcement, but mobile access to Live Mesh is available by pointing your phone browser to http://m.mesh.com. It's mostly a web view of the Live Desktop, though there is a feature to upload photos from your phone. However, for some reason that feature doesn't work for me right now. I don't get the "browse" button.
• ASP.NET MVC Preview 4 is available for download. Phil Haack has a few details that ScottGu didn't cover. Scott Hanselman shows off some AJAX stuff.
• Speaking of Scott Hanselman, he highlights the return of Terrarium from Bil Simser. Scott mentions that most Terrarium animal implementations were big collections of nested if statements. I wonder if F# pattern matching would be a cleaner approach?
• Ted Neward obviously never "even tangentially" touched politics, as I think they have far worse flame wars far more often than we have in the software industry. However, certainly the Scala flame war he's commenting on seems fairly counterproductive.
• Brad Wilson runs into a wall trying to convert a string to an arbitrary Nullable<T>.He doesn't find an answer, but I found reading thru the steps he took to try and find an answer strangely compelling.
• Jeff Atwood argues that Maybe Normalization isn't Normal. It's mostly a collection of information from other places, including a compilation of high-scale database case studies. But it's a useful collection of info and links, with a little common-sense thrown in for good measure.
• I have a hard time imagining Pat Helland camping.

Morning Coffee 167

• If you're a gamer, you're probably already well aware that E3 is this week. The Too Human demo has already been released. I have a friend who's been working on "something" that will be announced today (I think).
• Live Mesh folks pushed out an update Friday. Among the new features is the ability to sync folders among peers but NOT up to the cloud. This is cool because it means I can sync my many many GB of pictures and music on my home machine backed up with Carbonite. This means I can sync them without blowing thru my 5GB Mesh storage limit.
• It looks like there's a new F# drop - 1.9.4.19 - but as usual there is no announcement or details as to what's new. Release notes guys, look into it.  UPDATE - Don Syme blogged the release, and it's pretty minor. a .NET FX 3.5 SP1 bug fix, a fix for Mono, and they removed WebRequest.GetResponseAsync to make F# work on Silverlight. And the release notes are in the readme. My bad.
• Speaking of F#, it was "partially inspired" by OCaml, so when I see papers related to OCaml, I immediately wonder if I an apply the described techniques to F#. "Catch me if you can, Towards type-safe, hierarchical, lightweight, polymorphic and efficient error management in OCaml" is one such paper. (via LtU)
• Speaking of functional programming, Matthew Podwysocki posted a bunch of FP links as well as a Code Gallery Sample on FP in C#. Good stuff.
• As per Scott Guthrie, it looks like there's a new ASP.NET MVC drop coming this week.
• Based on posts by Ted Neward, Dare Obasanjo and Steve Vinoski, Google Protocol Buffers sounds like it's going to be a dud. Note, I haven't looked at it depth personally, I'm just passing on opinions of some folks I read and trust.
• Speaking of Dare, both he and James Hamilton take a look at Cassandra and come away impressed. I wonder how easy it is to code against from Python and/or .NET?
• Bart de Smet has a cool sample of calling out to PowerShell from IronRuby via the backtick command. Pretty cool, but it would even cooler to show how to call out to PS and return .NET objects to Ruby (though that would probably not be spec compliant for the backtick command).
• Here's a MS code name I had never heard before - Zermatt. It's "a framework for implementing claims-based identity in your applications." (via Steve Gilham)

Morning Coffee 166

Yes, I realize it’s been a while. I tried in vain to catch up with my blog reading after my Hawaii vacation and finally just gave up and hit “mark all as read”.

Dynamic Languages

• There's a new version of the DLR hosting spec available (doc, pdf). The DLR implementation is still in motion, so there are some inconsistencies between the spec and the code, but the spec should give you the high level overview you need if you want to host DLR languages inside your app.
• Oleg Tkachenko recently joined the dynamic languages team. He's the creator of the Interactive IronRuby Web Shell, an IronRuby version of Try Ruby. Of course, it’s not as cool as using SL2to execute the code directly in the browser. Michael Foord has his Python in the Browser and my teammates John and Jimmy demoed a Silverlight version of Try Ruby @ TechEd.
• Jim Deville, also of the dynamic languages team, recently started blogging.
• I have a new boss, Dave Remy. He doesn't have a blog - yet - but you can follow him on Twitter as daveremy. When Twitter is actually working that is.
• There's a new homepage/wiki for IronRuby though I’m not sure why there's a picture of Matz wearing a Python shirt on the home page.
• My teammate Jimmy Schementi provides some "continued hope" for a better (heck, I'll take current) ASP.NET and ASP.NET MVC story for DLR languages.
• Via Michael Foord, sounds like IronClad is making good progress. V0.4 can run the bz2 module "in its entirity" (maybe run a spellcheck on your site, guys?) and now apparently, it's now able to load numpy.core. Very exciting!

Other Stuff

• Pat Helland, who has blogged even less than me for the past few months, has a post up about controller and doers in the IT department. After 18 months in MSIT, put me in the doer camp, please.
• The F# team has pushed out a spec for v1.9.4 of the language. Don Syme says it's not official, but it's a huge improvement over the old informal spec
• Speaking of F#, my friend Matthew Podwysocki recently published FsTest, a testing DSL for F#. I wrote about F# unit testing as part of my PEG parsing series, and I really like the direction Matthew has taken this project. You can pull it down from CodePlex.
• When I did my PEG talk @ Lang.NET, Gilad Bracha mentioned I should check out oMeta. It looks really cool, though with the job change I haven’t had the time to play with it. Now I discover that Jeff Moser is working on a version for CLR called oMeta# that I’ve got to spend some time with. And in the comments to that post, I discovered pyMeta from Allen Short, though it apparently doesn’t work on IronPython (must investigate why).
• James Kovacs introduces psake, a PowerShell based build automation tool which uses a rake-inspired internal DSL syntax similar to one I blogged last year. I'd love to see this take off, but given MSBuild's tool integration, I wonder if that's feasible.
• I upgraded my home wireless network almost exactly a year ago. I've been happy with the range and coverage, but not so happy with the Buffalo Tech firmware. The built-in DHCP server is pretty flaky. So I upgraded to the open-source Tomato firmware. Upgrade was smooth, though I did need to reset my cable modem. But even that was smooth - Comcast has an automated service for that now,

Morning Coffee 164

• Big news since my last Morning Coffee post was the announcement of Live Mesh. I've been running it for about a month, and I'm really digging it. Make sure you check out the team blog and watch the developer tour video (be on the lookout for IPy about half way thru the video)

ALT.NET

• I had a great time @ the ALT.NET open space conference last weekend. I was somewhat distracted on Saturday as due to a family communication mixup, I had to bring my son Patrick with me. Jeffrey Palermo shot a cute video of him (3 minutes in) where he explains that he's at the conference "to be with my dad". Having a five year old is a little distracting, but everyone was amazingly cool with having him around. When he gets a little older I have no doubt he'll be attending conferences and leading open sessions.
• I did a session on F#, but it felt kinda all over the place. I hadn't touched F# in a few months and it showed IMO. Matt Podwysocki was there to help keep the session from devolving into mass chaos. Thanks Matt.
• My favorite session of the conference was Scott Hanselman's "Are We Innovating?" talk, which I think originated from a question I asked him: There are many examples of large OSS projects in other dev communities that get ported to .NET (NHibernate, NAnt, MonoRail, etc). Can you name one that's gone the other way? I can't.
• I took Matt's advice and joined the local ALT.NET Seattle group.

DyLang Stuff

• Martin Maly posts about how dynamic method dispatches are cached in three different layers by the DLR. You shouldn't care about this stuff if you're a DLR language user, but you will certainly care about it if you're a DLR language builder.
• I'm really excited to see Phil Haack (whom I met F2F @ ALT.NET) is experimenting with IronRuby & ASP.NET MVC. True, I'd rather it was IPy, but his Routes.LoadFromRuby would work with Python with very little code change.
• Note to self, take a deeper look at Twining, the IPy database DSL by David Seruyange.
• Daily Michael Foord - Ironclad 0.2 Released. Ironclad is a project to implement Python's C extension API in C# so that IronPython could load standard Python C modules like SciPy and NumPy. So far, they're able to load the bz2 module. 

Other Stuff

• Congrats to Brad and Jim for shipping xUnit.net 1.0.
• Everyone seems to be jumping on the functional C# coding bandwagon. Bart De Smet's series on pattern matching in C# is currently at eight posts. Now Luca Bolognese is in on the action, with three posts so far on functional code in C#. I like how Luca keeps writing that the C# syntax is "not terrible" for functional programming. Again, why suffer thru the "not terrible" syntax when you could be using F# instead? (via Charlie Calvert)
• I need to take a look at VLinq. Charlie and Scott Hanselman both mentioned it recently.
• I would like to have been in the conversation with Ted Neward, Neal Ford, Venkat Subramaniam, Don Box and Amanda Silver.
• I haven't had any time to play with XNA of late, which means the great list of GDC videos Dave Weller posted on the XNA team blog will remain beyond my ability to invest time for now.
• There's a new drop of Spec# from MS Research. IronRuby is using Spec# heavily as I recall.

Morning Coffee 160

I took most of last week between jobs and have spent much of this week getting machines setup, access to builds, etc. Furthermore, RSS Bandit ate my feedlist and I am still soldiering on sans mobile phone so I was pretty much unconnected for about a week and a half.

IPy Stuff

• Laurence Moroney demonstrates how to configure a web site project in VS08 to use Dynamic Silverlight’s development web server Chiron. I looked at turned it into an exported template, but I think the Start Options are stored in the suo file and I’m not sure how to include that in the template. Maybe it could be set w/ a macro or at worst a GAX recipe?
• If you’re a regular reader, you might as well get used to the name “Michael Foord”. He’s a developer @ Resolver Systems, makers of the IPy based Resolver One app/spreadsheet hybrid I’ve written about before. He’s also the author of the upcoming IronPython in Action book and the maintainer of Planet IronPython and the IronPython Cookbook. I’m going to try very hard to only link to Michael at most once per day. Frankly, that’ll be tough.
• Today’s Michael Foord Link: Michael turned his PyCon talk on IPy + SL2 into a series of articles entitled IronPython & Silverlight 2 Tutorial with Demos and Downloads.
• Ken Levy (who now sits just down the hall from me) clued me into the 1.0 release of IronPython Studio, which is a free IDE based on the VS08 Shell for IronPython (based on code from the VS SDK). Big new feature in this release is support for the integrated VS08 Shell, which means it’ll snap into your existing VS08 installation (well, not express) rather than forcing you to install the 300 MB isolated shell.

Other Stuff

• Caps had a BIG win last night when they needed it most. Now they’re tied with Carolina for the SE division lead, but they lose the tiebreaker so unfortunately, they can’t make the playoffs without help. ‘Canes have to head back home last night to play Tampa Bay, they have to win tonight and Friday to clinch. Loss in either gives the Caps control of their own destiny. Caps are only one game back of Ottawa, Boston and Philly, none of whom have played well down the stretch. It does mean I have to root for the frakking Penguins to beat Philly, twice.
• Now that I'm in a job where I'll be traveling occasionally, I really appreciated Scott Hanselman's travel tips, though I'm not sure "Don't look like a schlub" is in the cards for me.
• Unless you’ve been living under a rock, you’re probably aware that Scott Guthrie blogged that the ASP.NET MVC Source Code is available on CodePlex. The project name is “aspnet” not “aspnetmvc” which makes me wonder if they might release the source to more ASP.NET stuff over time.
• Speaking of Scott Guthrie, today he blogged about unit testing in SilverLight. Jeff Wilcox appears to have the definitive post on the subject, including links to the SilverLight testing framework (it’s included in the SL Controls source code release). He also provides a prebuilt “SilverLight Test” project template for easy download. Personally, I really like the in-browser test runner. I wonder how hard it would be to hook that up to DySL so you could write your tests in IPy? (given that IPy doesn’t have attributes, I’m guessing there’d be at least a bit of work involved in making this happen)
• Speaking of SilverLight, apparently the next version of Windows Mobile (i.e. 6.1) will support it. Since I'm in the market for a new phone anyway, I'm thinking of getting one of these. Also, it's nice to see a marketing site for WM 6.1 using Silverlight instead of Flash like WM 6.0 marketing site does.(via LiveSide)
• Ted Neward turns the news that MSFT is releasing XAML under the OSP into a long and fascinating history lesson that is well worth the read. I’m going to skip commenting on it, beyond advising you dear reader to read this if you haven’t already, except to wonder: how many sides does a “Redmondagon” have?

WebDev.WebServer PowerShell Function

In experimenting with NWSGI yesterday, I found I wanted the ability to launch the development web server that ships with Visual Studio (WebDev.WebServer.exe) from the command line. I hacked up the following PowerShell function and dropped it into my $profile so I can easily launch the web server in any directory any time I need. Thought I'd share:

There's probably an easier way to launch an exe with parameters than Sys.Diags.Process.Start, but it works. Using resolve-path is the key, that lets me pass in a relative path on the command line, but the script converts it to an absolute path in order to pass it to the webdev server. Also, I'm not sure I should have hard coded the path to the exe, but again it works and it's not like it's tough to change.

Enjoy.

Update: Tomas Restrepo pointed out an easier way to start the process:

I couldn't figure out how to correctly launch the exe when the physical path to serve has a space in it. Thanks Tomas.

Morning Coffee 159

As you might expect, these morning coffee posts are going to get more dev focused as well as more IPy focused.

• One of the cool things we showed @ PyCon was Django running on the latest drop of IronPython. IPy lead developer Dino Viehand posted a blog entry (for the first time in 28 months!) showing the basic Python DB provider for SQL Server he put together. Hopefully, we won't have to wait another two and a half years for Dino's next post.
• Speaking of IronPython, some of my new teammates pointed me to Michael Foord's Planet IronPython aggregate news site. Michael is IPy developer for Resolver Systems (the cool spreadsheet app hybrid I wrote about @ Lang.NET) and he's working on an IPy book.
• Still speaking of IPy, Jeff Hardy dropped his first release of NWSGI, an port of Python's Web Service Gateway Interface spec to ASP.NET and IPy. I can't wait to see NWSGI combined Django running on IPy like Dino demoed @ PyCon. Congrats Jeff!
• Scott Hanselman's post on Twitter reminds me that I recently started twittering myself. I haven't worked it into my daily routine, so it gets updated only occasionally, but after reading Scott's post, I'm thinking it's cooler than it appears on the surface. 
• In surprising news, Microsoft is going to start collaborating with IBM's Eclipse Foundation, to make it easier to it easier to write apps for Windows in Java. I would think this is a very cool thing, but apparently Ted Neward - who's knowledge of JavaWorld far eclipses (ha ha) my own - thinks "the skin here is just too sensitive" and that this move might cause more controversy between MS and Java. However, he seems to imply the controversy would be between MS & Sun (Eclipse is obviously named as a jab @ Sun) rather than between MS & the Java community.

Lunchtime Coffee 153

• p&p have published new versions of both the Web Service and Web Client Software Factories. Beyond support for VS08, I'm not sure what's new but that's worth the price of download (admittedly close to zero) right there. I assume these need the most recent release of the Guidance Automation Toolkit as well.
• W3C has published a new working draft of the Service Modeling Language. I'm really interested to see where this technology goes.
• Yesterday, Microsoft announced the Silverlight Blueprint for Sharepoint, part of a larger Software + Services Blueprints initiative that I wasn't aware of. According to Michael Lehman (who's blog I've been been remiss to read of late), S+S Blueprints has a bunch of other interesting projects including Video.Show and Outlook+Services.
• Martian Maly demonstrates how you can use DLR trees to build a statically typed add function. Literally, my very first thought after Martin presented DLR Trees @ Lang.NET was "I wonder if you could use that for static languages too?" I guess the answer is yes.
• It's been six months, and Scott Hanselman still isn't evil. Perhaps he could start turn his ASP.NET wiki into an evil ASP.NET wiki? Actually, I'm only linking to his post because I liked the way he described blogging as "I'm writing a book that will never end".

Morning Coffee 146

• The writers strike is officially over. Everyone goes back to work today. Thomas Cleaver has what I thought was the best post summarizing how the writers won. TV Guide has a rundown of how and when various shows will resume. I can't wait to see Daily Show and Colbert Report tonight. Lost - aka the best show on TV - looks like it will be getting five more episodes (in addition to the eight shot before the strike).
• Speaking of TV, Battlestar Galactica Fans: circle April 4th on your calendar.
• Obama won all three "Potomac Primaries" yesterday, and is now the Democratic front-runner, though there's a long way to go before the convention. Scott Adams of Dilbert fame has a great take on presidential experience - I'm guessing he's an Obama fan.
• In minor acquisition news, Microsoft is acquiring Caligari, makers of 3D modeling tool trueSpace. The Caligari folks are joining the Virtual Earth team, though I wonder what the XNA folks think of the acquisition. This isn't the first 3D modeling product Microsoft ever acquired - we owned Softimage for four years in the '90s.
• Scott Hanselman and Tomas Resprepo both write about PowerShellPlus, which I saw week before last @ Lang.NET. Scott really likes it, for both PS novices and gurus, but Tomas thinks the UI is busy, based on the screenshots. Personally, I'm not doing much PS work lately - occasional one off stuff, but that's it - so it doesn't seem worth the effort.
• Speaking of Scott & Tomas, Scott also has a nice gallery of VS themes. I'm partial to Tomas' Ragnarok Grey. Is there a VSThemesGallery.com site somewhere?
• Still speaking of Scott, he points to the new ASP.NET Developer Wiki (beta). I poked around, but didn't find anything shiny. I was very surprised that searching for "MVC" returned no results.
• Speaking of MVC, Scott Guthrie has a rundown on what's coming in the MIX preview release of ASP.NET MVC. Biggest news IMO is that it's /bin deployable - i.e. you don't need your hoster to do anything special to support MVC (assuming they already support ASP.NET 3.5). Also big news, they're releasing the source so you can build and patch (and enhance?) it yourself.
• Chris Taveres continues is ObjectBuilder series and Tomas continues is DLR Notes series. BTW, my F# based DLR experimentation continues, albeit slowly (frakking day job). Hope to be able to post on this soon.
• One of the things driving my interest in F# is manycore. An interesting tangent to manycore is general purpose programming on graphics processing units (aka GPGPU). MS Research just released a new version of Accelerator, just such a GPGPU system. I personally haven't played with it - I've been focused on writing parsers, not parallel code.
• Is XQuery really "a promising technology of the future" as Don Box suggests? I see exactly zero demand or use for it in my day-to-day work. Of course, Don's paid to build future platform goo, so maybe it is promising and Don's afore-mentioned goo will leverage it, though I remain skeptical. As for XML being "Done like a well-cooked steak", I'd say XML is like a great steak cooked perfectly, except it's done exactly how you don't like it. You can appreciate its quality, but you don't really enjoy it as much as you could have.

Morning Eggnog 132

• My parents are coming into town tomorrow so I'm off for the remaining week or so of the year. Blogging will likely be non-existent, unless I blog something I come up with while geeking out with my dad.
• Juergen van Gael demonstrates how to use TPL from F#. He wrote this once before using F#'s async workflows feature. I like the TPL version, though the "new Action<int>(RowTask)" is a little wordy. I'm guessing the eventual F# syntax will probably become something compact like "action RowTask". (via Don Syme)
• Andrew Peter ported RoR's Haml view engine to ASP.NET MVC, calling the result NHaml. I haven't played around with the new MVC stuff much, but I'm guessing ASP.NET's control-based approach doesn't work well when you separate out the controller code. If I'm manually authoring view templates, I'd much rather type NHaml's syntax than the standard ASP.NET <% ...%> syntax. On the other hand, there aren't any design tools out there today handle the NHaml syntax. Also, I wonder if Andrew is working on a Sass port. (via DNK)

Morning Coffee 131

• On a recommendation from my mother-in-law, I've been watching Torchwood. Sort of Men in Black, the series and set in Cardiff. Since it's made in England, it'll be one of the few shows still running in the new year due to the WGA strike.
• A while back I pointed out that many DotNetKicks articles were submitted by their authors. I submitted a few of my own, just for kicks (har har), with mixed results. Today, I discovered that the parse buffer post from my Practical Parsing in F# series was submitted, picked up some kicks, and made it to the home page. That's pretty cool. I guess writing more dev-focused articles is the way to go to get attention on DNK.
• Amazon has rolled out a limited beta of SimpleDB, which appears to be S3 + query support. Cost is based on usage: 14¢/hour for machine utilization, 10¢/GB upload, 13-18¢/GB download and $1.50/GB storage/month. I'd love to see SimpleDB software that I could download and install, rather than hosted only. Even if I was going to use the hosted service, I'd like to develop against a non-hosted instance.
• Research for sale! I was checking out the MS Research download feed and discovered a link to the Automatic Graph Layout (MSAGL) library. This was previously called GLEE (Graph Layout Execution Engine) and was "free for non-commercial use". Now, you can buy it for $295 from Windows Marketplace (though the previous free version is still available). The idea of directly commercializing research like this strikes me as pretty unusual. It must be a really good library.
• Scott Guthrie shows off the new Dynamic Data Support that will ship as part of the ASP.NET Extensions. I'm like, whatever. Scaffolding wasn't that that interesting to me in RoR, so it's no surprise that it's not that interesting in ASP.NET.
• Jeff "Party With" Palermo blogs about the IoC support in the new MVC Contrib project. Also looks like they're porting RoR's simply_restful. (via Scott Guthrie) 
• I need to try out some of Tomas Respro's VS color schemes (also via Scott Guthrie)

Morning Coffee 129

• Short coffee this morning, as I'm home with a tweaked ankle.
• I started playing Indigo Prophecy over the weekend. It's an original Xbox game, released as part of the new Xbox Originals program. It has a good metacritic score (84), though apparently it wasn't much of a retail success. I'm enjoying it, though it's not very challenging. It's more an interactive movie than a game. Good story, though.
• The ASP.NET MVC preview dropped today, Scott Guthrie has the details. Scott Hanselman has a 40 minute how-to video and Phil Haack has several articles up already.
• Speaking of ASP.NET MVC and Scott Guthrie, he's got another post in his series on ASP.NET MVC. This time, he's covering how to handle form input / POST data.
• Erik Meijer has posted some of his thoughts on Volta. He's one of the guys behind Volta, so it's worth a good look. (via Dare Obasanjo)
• Late Addition - the ASP.NET Extensions is more than just the MVC stuff. It also includes AJAX improvements, Silverlight support, ADO.NET Data Services and ASP.NET Dynamic Data Support. Data Services (formerly Astoria) let's you easily expose your database via RESTful services. I think Dynamic Data Support used to be code named Jasper. It's a "rich scaffolding framework" for ASP.NET. I assume that's to compete w/ Ruby on Rails.

Morning Coffee 128

• After using Outlook 2007 as my RSS reader for a few months, I've gone back to RSS Bandit. I run two work machines (desktop + laptop) and I finally got tired duplicated blog entries because each copy of Outlook downloads the same post. Also, for some reason Outlook downloads the same Technorati posts over and over again.
• ADO.NET Entity Framework Beta 3 was released. The latest CTP of the EF Tools is also available. And as per the press release, EF has gained support from "Core Lab, DataDirect Technologies, Firebird Foundation Inc., IBM Corp., MySQL AB, Npgsql , OpenLink Software Inc., Phoenix Software International, Sybase Inc. and VistaDB Software Inc". I'm not sure what that means, exactly, but I guess you'll be able to LINQ to Entities on a wide variety of DB platforms. Interesting Oracle isn't on that list. Not really surprising, but interesting.
• Here's a new ASP.NET MVC article from Scott Guthrie, this one on views and how you pass data to one from a controller. Using generics to get strongly-typed ViewData is pretty sweet. But where's the MVC CTP that was supposed to be here this week?
• In news about web app tool previews that did ship this week, Live Labs announces Volta. Haven't installed or played with it yet, but I did read the fundamentals page. It primarily looks like a tool to compile MSIL -> JavaScript, so you can write your code in C# but execute it in the browser. Sam and Jesus are excited, Arnon not so much. Arnon's argument that being able to postponing architectural decisions is to good to be true is fairly compelling, and not just because he quotes me to support his argument. But I'll download it and provide further comment after I experiment with it myself.
• Simple Sharing Extensions is now FeedSync. Not sure what else is new about it, other than it's been blessed with "1.0" status. The Live FeedSync Dev Center has an introduction, a tutorial and the spec. (via LiveSide)
• Dare likes tuples. Me too. I also like symbols.

Morning Coffee 127

• I'm back at the office today after almost two weeks away. So "catch-up" is the official hyphenated word of the day.
• Big news last week was an update on Silverlight. The next version (the one with the embedded cross-platform CLR in it) was rebranded Silverlight 2.0 and will include higher-level UI framework features and richer networking support. Look for a go-live beta Q1 next year.
• According to Scott Guthrie, there should be a CTP of the ASP.NET 3.5 Extensions this week, including the new ASP.NET MVC framework that many folks await with baited breath. Scott posted the second in new series on this framework, this time covering URL Routing.
• After a long blog silence, Pat Helland posted four presentations that he delivered @ TechEd Barcelona. They're pretty much required reading as far as I am concerned. Here's hoping the TechEd Barcelona folks recorded at least the audio of these sessions.
  • Metropolis: Interchangeability of Operations
  • Life Beyond Distributed Transactions: an Apostate's Opinion
  • Data on the Inside versus Data on the Outside
  • The Irresistible Forces Meet the Movable Objects
• There's a new drop of F#, v1.9.3.7. Don Syme calls it "a release candidate for F# 1.9.3". Full release notes are over on his blog.
• Speaking of F#, Douglas Stockwell explains how to roll-your-own F# Express by combining the F# download above & the VS08 shell.
• Still speaking of F#, Robert Pickering has written an article on Active Patterns as well as a series on concurrency in F#. So far he's covered Async Workflows (twice), Erlang style messages and message queuing.
• Speaking of concurrency, Soma announced the CTP of ParallelFX last week. This includes Parallel LINQ (aka PLINQ) and Task Parallel Library (aka TPL). Also check out their whitepaper, team blog and dev center.
• I'm a big fan of the Architecture Journal. Now you can get all that great content in a great WPF-based app. Simon Guest has the details.

Afternoon Coffee 123

• Morning Coffee is late this morning because we went for our Christmas portrait this morning and it took forever. The pictures turned out great though.
• Nick Malik finishes up his series on business operation models by covering the diversification model. Also, Nick's points about the synergy between a diversified model and the coordinated model are spot on. I happen to be a big fan of those models (aka the models with low standardization) which probably drives some of the  more my "unique" perspectives on SOA.
• Scott Guthrie starts out a new series and future technology, this time it's ASP.NET MVC Framework that gets the series treatment. The first entry in the series is a general overview. I wonder why there's no cool code name for the MVC framework? Whatever it's named, I like the auto routing and action rules - it seems very Rails-inspired.
• Over the weekend, Don Box points out that the REST authentication story "blows chunks". I've recently given up on the reliable part of the original "Secure, Reliable, Transacted Web Services" vision - and I never believed the transacted part. Security, on the other hand, is the one part of that original vision that has worked out IMO. My experience with the WS-* security stack has been pretty good, though Dare Obasanjo thinks that OpenID and OAuth are the final nail in the WS-* coffin.
• Speaking of Dare, he goes on to say WS-* is to REST as Theory is to Practice. He makes the point that "The only times I encounter someone with good things to say about WS-* is if it is their job to pimp these technologies or they have already “invested” in WS-* and want to defend that investment." I gave up pimping evangelizing technology a while back and I don't want to be in the position of defending a bad investment, so I'm spending lots of time looking at REST.
• Jesus Rodriguez takes a look at the Managed Services Engine and comes away excited. Jesus is a self-described "strong believer" in SOA governance. I'm a self-described strong disbeliever in SOA governance, so MSE sounds like more of the Worst of Both Worlds to me.
• A little light reading: I pulled Applied Cryptography and A New Kind of Science out of my garage last weekend. Plus my copies of RESTful Web Services and Programming Erlang just arrived yesterday.

Morning Coffee 122

• Sorry for the posting lag. Had a few technical difficulties around here. In the process of moving hosts, so expect more glitches.
• My talk at the p&p Summit on Monday went really well. At least, it felt good and the applause at the end felt genuine. I recorded the audio on my laptop, so I'll be posting a Silverlight version as soon as I figure out how to adjust the levels so their somewhat consistent. Paraesthesia and #2872 have reactions.
• Speaking of the p&p Summit, Scott Hanselman posted his ASP.NET MVC demo from his talk. Said ASP.NET MVC bits aren't available yet, so you can't, you know, run the demo for yourself. But at least you can review what the ASP.NET MVC code will look like.
• I stopped by the SOA/BPM conference last week and saw Jon, Sam and Jesus among others. Spent quite a bit of time talking to Sam and his Neudesic colleagues about this "physically distributed/logically centralized" approach that I think is hogwash. It sounds to me like Neudesic approach is really federated not centralized, though I'm not sure David Pallmann would agree. Federated makes much more sense to me than centralized.
• Nick Malik continues his series on SOA Business Operations Model. I especially like his point that this isn't a series of choices, you need to "look at your company and try to understand which model the business has selected. "
• The first CTP of PowerShell 2.0 is out! Check out what's new on the PowerShell team blog and Jeffrey Snover's TechEd Presentation. (via Sam Gentile)
• Soma announced updates to VC++ coming next year, including TR1 support and a "major" MFC upgrade to support creating native apps that look like Office, IE or VS. I get supporting TR1, but the idea that people are clamoring for MFC updates is kinda surprising. Many years ago when I first came to MSFT, a friend asked "But don't you hate Microsoft?" to which I responded "No, I just hate MFC". Obviously, not everyone agrees with that sentiment.
• Steve Vinoski thinks there's no hope for IT. Funny, I keep agreeing with Steve's overall point but disagreeing with his reasoning. I still don't buy the serendipity argument. I like compiled languages. And I think he's overstating the amount of "real, useful guidance" for REST floating around. Basically, there's "the book".
• In widely reported news, Windows Live launched their next generation services. Don't bother with the press release, just go to the new WL home page.
• Speaking of WL, Dare Obasanjo points to the Live Data Interactive SDK page where you can experiment with the WL Contacts REST API. It gives you a good sense of how the Web3S protocol works. Pretty well, IMO. However, how come WL Contacts Schema doesn't include some type of update timestamp for sync purposes? If you wanted to build say a Outlook <--> WL Contacts sync engine, you'd have to download the entire address book and grovel thru it for changes every sync.
• Speaking of Web3S, I'd love to see some info on how one might implement a service using Web3S. Yaron Goland positions Web3S as an alternative to APP that WL developed because they "couldn't make APP work in any sane way for our scenarios". I'm sure other folks have similar scenarios.

Morning Coffee 119

• The biggest news of the week IMHO is Soma announcing the formation of an F# product team. Specifically, they will "fully integrate the F# language into Visual Studio and continue innovating and evolving F#." Though Soma calls F# "another first-class programming language on the CLR", I get the feeling there won't be a "Visual F#" sku. Don Syme has more on the news.
• In other Soma announcement news, Popfly is now in beta. More details on what's new on the Popfly Team Blog. I haven't played with Popfly in depth, but I think it's got huge potential.
• Scott Guthrie details the upcoming ASP.NET MVC Framework. Personally, I'm not building web apps much these days, so I'm not really invested one way or the other. Given the interest in this approach, it's nice to see the ASP.NET team respond to the market, though I'm sure someone will complain that we're trying to kill off the various open-source MVC Web frameworks that have sprung up.
• Over in Windows Live, they shipped a new version of Live Search Maps, upgraded WL Photo Gallery (which I've been digging) to support Flickr and shipped an update to WL Accounts which allows you to link accounts.
• The Clarius folks keep churning out great tools for software factory developers. The latest is the T4 editor, which brings intellisense, color syntax highlighting and property inspector support for Text Templating Transformation Toolkit (aka T4) files. T4 files are used for code generation in both DSL Toolkit and GAT.
• David Pallman (again via Sam Gentile) suggests there are only three choices for infrastructure architecture: None/Point-to-point, Centralized/Hub-and-Spoke and Thin/Bus. I get the first two, but his explanation of the third goes to far into the "magic framework" category for my taste. "Physically distributed but logically centralized"? That doesn't make any sense to me at all.
• Fellowship of the Ring makes its way onto XBLM. Alas, not in HD so I'll stick w/ my extended four hour DVD version thankyouverymuch.

Morning Coffee 117

• Quick update to the DevHawk 2007 World Tour: I won't be making it to the SOA & BP Conference. Riley's having her tonsils out. As much as I'd like to hang with my geek peeps, family is the priority. But I can still make an evening event or geek dinner later in the week if anyone is game.
• Caps season-opening winning streak continues. Still 100% on the PK, though the power play is pretty anemic. As I said yesterday, it's WAAAAY to early in the season to start bragging, but starting strong is much better than starting weak.
• Speaking of hockey, looks like the NHL Network is launching in the US this month (it's been available in Canada since 2001). Also, NHL.tv is up and running. Those wishing to see Caps highlights can go directly to Capitals.NHL.tv. Unfortunately, if you want to see full games, you've got to subscribe to Center Ice or Center Ice Online to the tune of $150. But I don't want to get "up to 40 games each week", I just want the Caps games. Between the time zone difference and kids, it's not like I have time to watch that much hockey anyway. Why can't I subscribe to just the Caps games online for say $25 a season?
• Finished Halo 3 Sunday night. Fun game and a great end of the trilogy. Looking forward to what the newly-independent Bungie does next. Something tells me we haven't seen the last of Master Chief. However, I do think Bioshock has better and more original storytelling. Mass Effect looks like it'll be better still.
• Sam Gentile pointed out that his Neudesic colleague David Pallmann has posted a series of WCF tips. Several of them are right on the money like "Take Advantage of One Way Operations" and "Use a Discovery Mechanism to Locate Services". However, I can't agree with "Maintain a Service Catalog". David warns that if you don't, "The left hand won’t know what the right hand is doing." Of course, that's probably the case regardless of how you maintain your service catalog. And "Retry on minor failures"? That's fine, if you've got an idempotent operation. Unfortunately, most non-read operations aren't idempotent unless you take the time to design them that way. And most people don't.
• Speaking of Sam, he's blown up his CodeBetter blog and walked away from the ALT.NET crowd. I've not been a fan of this ALT.NET stuff since it surfaced - as Sam said, "ALT.NET is a divisive thing" - so I'm happy to see my good friend walk away from it.
• Speaking of ALT.NET, Scott Hanselman blogged about previewing the new ASP.NET MVC Framework at the ALT.NET conference. Like Sam, Scott thinks the term ALT.NET is "too polarizing". I like Scott's suggestion for Pragmatic.NET. Oh, and the MVC framework stuff looks cool too.
• Reading Dare's description of OAuth gave me a distinct sensation of deja-vu.

What is the Rails Question?

Nick Malik asked "what is the Rails "answer" on the Microsoft platform? If we don't install Ruby, do we use Rails on JS or is there a Rails version we may want to put up ourselves?" I guess it depends, what is the Rails "question"?

On the one hand, the question could be "What's the best way to run Rails on Windows?" I think the short answer to that is IronRuby. In the wake of the IronRuby announcement, John Lam wrote that "Nobody would take our implementation seriously if it doesn't run Rails." Some people question the DLR's teams ability to ship a compatible version of Ruby without looking at the source, but my money is on the DLR team. (Of course it is, I'm a kool-aid drinker!)

BTW, I don't think having a JavaScript port of Rails (JailS?) is much of a help for the Microsoft platform. I'm not sure if Steve Yegge's JavaScript Rails port would run on JScript.NET, but I wouldn't bet on it. I would expect you need either the old Active Scripting JScript or the new Managed JScript (aka the DLR based version of JavaScript). Of course, IronRuby runs on DLR as well so why wouldn't you just run Rails on IronRuby instead of the JavaScript port of Rails on Managed JScript?

(Side note - why isn't the new JScript engine called IronJavaScript? Wouldn't that be cooler than Managed JScript? Don't they know "Iron" is the new "#"?)

On the other hand, maybe the question is "can ASP.NET evolve to be more Rails-esque?" I think it's starting to, slowly. Rails at it's core is a Model View Controller web app pattern (aka Action Pack) combined with an Active Record data access pattern (aka Rails' Active Record). Certainly, nothing stops you from using a similar approach with ASP.NET. The Castle Project has an ASP.NET implementation of MVC (aka MonoRail) and Active Record (also called Active Record). But I assume Nick's more interested in what ships natively in the platform to compare to Rails.

On the data access side, I think LINQ to SQL is a a compelling alternative to the various Active Record implementations. It's not an implementation of the Active Record pattern, it looks more like a Table Data Gateway patten. Also, it's not DRY like Rails Active Record, but I think that's more of a function of dynamic vs. static languages. Castle Active Record isn't DRY either. But once you get the hang of the slightly funky syntax (the from clause is first so you can get intellisense) I find LINQ very easy to use. Certainly, building Query Objects is a snap.

On the web app framework side, the story isn't so pretty. The agile folks like MVC because it's easier to test (among other reasons - see update below). Apparently, there's an ASP.NET MVC framework that's "in the works", but AFAIK no one has seen or heard anything about it since the MVP summit. Jeffrey Palermo was impressed with what he saw, but I guess everyone else has to reserve judgement until it gets a little more public.

Actually, I don't think it's an either-or question, it's both. In order to be the Common Language Runtime, I think it needs to support common dynamic languages like Ruby, Python and JavaScript natively. And, in order to be the best platform, I think the .NET Framework in general and ASP.NET in particular need to support multiple approaches to meet the needs of different developers.

UPDATE - in the comments, Jeffrey Palermo points out that he likes MVC "mostly because it separates concerns of controlling screen and rendering the screen. It makes the application more maintainable and keeps the code easily changeable." Point taken. I didn't mean to imply that testability was the only virtue of MVC.

Morning Coffee 17

Yesterday's Morning Coffee was canceled on account of barfing. For all the gory details (you have been warned), check out my wife's blog.

• Only 12 responses to the State of the Union were posted as I write this. Dunno why, but I was expecting more. Maybe this whole Web 2.0 thing is overblown a bit! :)
• Speaking of the State of the Union, is it just me, or did anyone else find it odd that the Scooter Libby trial started the same day?
• Atlas ASP.NET AJAX 1.0 is done. Lots more on this from Scott Guthrie's blog. While I'm not personally that interested in ASP.NET AJAX itself, two things strike me as interesting in this release. First, we're shipping all the code for this. The client side JavaScript library, the Control Toolkit, even the server-side components. Second, it's nice to see the Developer Division shipping something this significant without waiting for the next release of Visual Studio. Here's hoping that both of these two trends continue.
• Rich McCollister pointed me to the XmlProviderLibrary. Bad on me for not looking harder.
• Windows Live Writer is pretty cool, but it is missing one feature that I needed twice Tuesday. While embedding images in a post is cake, there doesn't seem to be a way to embed non-image files. You know, like the ColorConsoleTraceListener Project or the Live Search for Chartity Search Providers. I'm guessing the infrastructure to post images and files would be identical, but there's no UI interface for it. I checked out the WLW SDK online and found the ISmartContent.Files.Add method, so I'm guessing it's doable. But there's no such animal on the Live Gallery. I wonder why nobody else has built this yet? Is this really that unique a request?

Morning Coffee 16

• Forgot to say this yesterday, but I'm happy the Colts are in the Super Bowl. Well, I guess I'm more happy that New England isn't in it. They've won it enough lately. I wish the Saints has made it, but at least this way I have no question who to root for on Super Bowl Sunday.
• My Gamerscore cracked 1000 over the weekend. I got 60 points in Dead Rising and 100 points in NHL 07. I have played ten games + three arcade games for a maximum possible Gamerscore of 10,600 and a Gamerscore "conversion rate" of 10.28%. I wonder how good that is? All the leader boards I've seen rate purely on Gamerscore.
• Speaking of games, Obsidian (of Neverwind Nights fame) is working on an Aliens RPG! Check out this post by Chris Avellone of Obsidian on Game Design Research (via Game Tycoon).
• Richard Grimes' .NET Instrumentation Workshop rocks. Richard also has extensive workshops on .NET Security and .NET Fusion (aka runtime binding). If they're as good as the instrumentation workshop, they're worth a read.
• In my SSB/WF prototypes, I've simply been writing to the console. The lo-tech brute force works okay for a console app, but not at all when I move my code into a shared library. So I decided to bite the bullet now and translate the Console.WriteLine calls into TraceSource calls. My prototype isn't that big (yet), but it went pretty smooth nonetheless. I currently have three TraceSources in my solution - one for the host, one for my SSB activities & workflow service and one for the persistence engine (I just inherited from SqlWorkflowPersistenceService and added the trace calls). I'm sure in time, I'll wish I had set up my TraceSources differently, but for now it works.
• The one feature I lost moving from Console.WriteLine to TraceSources was color support. Since I am creating voluminous tracing data, I used color coding to indicate which part of the application the trace information was coming from. Of course, the OOB ConsoleTraceListener doesn't have any mechanism to color code the output. I hacked up a ColorConsoleTraceListener in a couple of minutes that worked great. I say "hacked" because my color choosing code is currently hard coded, rather than being stored the config file. If I get the time to change that, I'll post the code here.
• While researching ASP.NET's Membership system, I found this Scott Guthrie post with links to ASP.NET providers for MySql, Oracle and SQLite. I've wondered about the lack of a simple file-based ASP.NET role/membership provider and even started hacking together an XML based one. But the availability of a .NET SQLite data provider makes that an interesting option. XML would be human readable, but porting the existing SQL providers to SQLite would probably be easier.
• Politics 2.0 in action: Talking Points Memo is enouraging you (aka Time Magazine's Person of the Year) to record your own response to tonight's State of the Union. Basically record your response via camcorder, webcam or cellphone. Then upload it to YouTube and add it to the TPM SOTU group. With President Bush's approval rating at all time lows, I'm guessing these videos will be venting some of the pent up hostility towards this administration.
