Oslo May 2009 CTP Available Now

The May 2009 CTP of “Oslo” available on the Developer Center contains a new unified setup, an Intellipad with an integrated DSL authoring mode, the UML domain and the CLR domain, a slimmed-down SDK with the samples and the documents available on the DevCenter, a unified tool set for the “M” language and, the one that folks have been most anticipating, Quadrant.

For more details about what’s new, check out the letter from Kraig and Kent and the release notes. Also, in the coming weeks and months, Kraig and Kent have a pipeline of content for the DevCenter to keep you informed about how we’re using “Oslo” and how you can use it better. If you’ve got suggestions, please use the Connect site and don’t hesitate to post your questions on the forum.

Enjoy!

“Olso”: Hot or Not?

A coupla weeks ago, I did two days with of meeting, greeting, talking and interviewing at a Dutch company in The Netherlands named Sioux. They do a conference with the politically incorrect name of “Hot or Not,” which includes an even more politically incorrect picture of two women as part of their advertising, one lovely and one… less so. They have done this conference 12 times before (I was lucky number 13, just like Bilbo) and the goal is to have someone known for a particular technology come and give a talk, e.g. Alan Cox on Linux, and then rate the technology as “Hot” or “Not.” Since they couldn’t get someone good for Oslo, they had to settle for me.

I spent day one having lunch with the Sioux engineers who were very insightful in their questions about how models fit into their process (all kinds of ways), how it works for embedded systems (XML generation), how it works across platforms (MSC and OSP, baby!), etc. After lunch, I had time to work on my demos and slides (whew) and play with a desktop electron microscope. We must’ve spent an hour looking through fly parts at 26,000 times magnification. They build seriously cool software at Sioux!

My “Oslo” talk was 2.5 hours long with a 30 minute cocktail break. I thought the Dutch were loud before the alcohol was served, but that was nothing… : )  There were 120 attendees in the room they’d set aside for me, and they’d turned away another 60 more that had wanted to come. I did Don Box and Doug Purdy’s “Lap Around Oslo” talk with a German twist (“this picture of the Fairytale Castle is a model, not the castle itself”), David Langworthy’s M talk (“let’s parse a simple sentence”) and showed off Spork, WIX, MUrl and MService. The audience’s questions were even more insightful, e.g. what about schema versioning? Why a new language? How do you debug a declarative language? Can I embed languages in each other? What if I want to use an M language without a database at all?

At the end, I was awarded a book on Dutch culture (very useful! Now I know why the bicycles throw themselves in front of my car and why it wasn’t such a big deal as I thought for me to have to drive up on the sidewalk a little…). And then, without so much as a courtesy screen, the vote was called right in front of me — thumbs up, Oslo “hot” or “not?” I was to learn later that this is a serious thing — they’ve rated at least one technology as only 30% hot.

Luckily for my pride and my continued employment, Oslo was rated 98% hot. That made the magazine interviewing the next day much less embarrassing I’ll tell you!

James Clark Getting Involved in M

James Clark, the father of the world's fastest XML parser (according to his bio) is helping us with M on the M Specification Community. He had some initial thoughts that I thought were interesting. I'm sooo glad he's keeping us honest!

Dutch “Computable” Interviews Chris Sells on Oslo

The translation from Dutch is pretty good: “The better you can describe applications in models, the less code you need to write and the more transparency you provide to developers and others.” Computable spoke with Chris Sells. De programmamanager van de Connected Systems Divisie van Microsoft was in Nederland voor een Hot-or-Not lezing, georganiseerd door Sioux. The program manager of the Connected Systems Division of Microsoft in the Netherlands for a Hot-or-Not reading, organized by Sioux.

But they chose the strangest picture…

Joel Spolsky talks about Wasabi: His FogBugz DSL

In Scott Hanselman's April 2009 podcast, Visiting Fog Creek Software and Joel Spolsky, Joel talks about Wasabi, FogCreek’s VBScript compiler, and he talks about it really being a subset of VBScript used specifically for bringing FogBugz to Unix and the CLR. In fact, it's a VBScript compiler built specifically to compile a single application, doing things like making the 5% of ADO.NET they use cross-platform. And just in case the point isn't completely obvious, Joel and Scott draw the conclusion for us: Wasabi is the domain-specific language just for FogBugz. Just another DSL in nature.

Three “Oslo” Talks at VSLive in June!

This year’s VSLive in Las Vegas (June 8-11), has three, count ’em three, “Oslo” talks! (And a Dublin talk to boot.) Just a few months ago, the “Oslo” team was giving all the talks and now there are so many of them I have to hear about them on the street! Our baby grew up so fast…

And as if that weren’t enough, Jon Flanders gave me a code for a discount:

“If you register with code S9V10 you can get and all-access Passport Package for just $1,295, a savings of $400.00 off the standard price of $1,695.”

I know I loved MIX in Vegas last month and I’m jealous I don’t get to go back in June. Put some money down on 22 for me!

Real-World Credit Card Validation Rules w/ “Oslo”

This is a wonderful article on the use of an "M" grammar to parse a set of rules specific to credit card validation and then parse those rules at run-time to drive a framework for doing the validation itself. The article does a marvelous job of motivating the use of a custom DSL for construction and validation by non-engineers and then lays out the entire grammar and C# loader code. Recommended.
