The “Oslo” team heard you! There was some “regression in the quality of the bits” in the Jan CTP from the PDC CTP that affected you guys in our 3-pane mode for grammar editing in Intellipad (aka the bits are worse than they used to be). It was just a sample, but it’s so so useful, that language developers are using the hell out of it, which means they’re running into “performance and robustness issues” (which means it was slow and crashed) and we’ve fixed the worst ones in the January 2009 “Oslo” SDK Refresh.

You have to uninstall the three things that are called “Oslo” before you install and there are no new features or other changes — this is just to make the 3-pane mode better.

Please bang on it, ask your questions and report your issues. Thanks!

Oh, and 3-pane mode will be an official part of the product in future CTPs, so it will receive the same testing love as the rest of the project. We heard you!

Magnus Christerson, the Vice President of Product Management from Intentional Software Corp, founded by Charles Simonyi, is giving the very last talk at the DSL DevCon, so make sure to stick around!

Also, seats are filling up FAST, faster than any of the other DevCons. Make sure to register now if you’re coming! And don’t forget, it’s free!

Apparently there is quite a bit of pent up demand for this conference, as there were more than 50 session proposals for only 12 slots and we’ve already filled half the seats with just pre-registrations.

Sessions include an M deep dive by Paul Vick, DSLs in Groovy by Guillaume Laforge, DSLs in Eclipse by Markus Voelter, a functional vs. dynamic DSLs smackdown by Ted Neward, a DSL for Pixel Effects from Adobe and last, but certainly not least, giving the keynote for the entire conference, the undisputed Duke of DSLs himself, Maaaaaartin Foooooowler-er-er-er!

Come to Lang.NET and stay for the DSL DevCon or just come to the DevCon, but whatever you do, sign up for the FREE DSL DevCon right now! All 5 of the other DevCons have sold out and I expect this one to be no different.

Long-time readers may recall when I got an angry caller from a Vista user that had trouble configuring it the way they wanted it. They got to me because they were looking for “sales” using the automated voice attendant that matched my last name instead (“Sells”) and forwarded him to me in the middle of a 1:1 in my office. Not wanting to let a customer go away angry, I stopped what I was doing and did my best to try to help.

It happened again today, except for an angry middle-aged guy, I got a call from the sweetest 12-year-old girl you’d ever want to talk to. Her Word CD had gotten scratched and she needed a replacement so she could write a big paper due next week. I considered telling her that I wasn’t in sales or support or getting her number and calling her back (I was IM’ing with four other people at the time and I was late for a meeting), but she was so earnest that I just couldn’t turn her away.

Instead, I took her name, address and email, went to the MS store and purchased her a copy of Office 2007, which I then had sent to her place via 2-day shipping, all the time assuring her that it wouldn’t cost her a dime. I ended up using my own personal quota for discounted software and charging $60 to my MS AMEX, but I would’ve spent my own money (and still might if my boss reads this and rejects my expense report : ).

She was so grateful and it made my day to solve her problem. I love our customers and I hope the terrible robot on the main MS line keeps sending ’em my way.

Doug Purdy and I will be giving an “M” talk about web stuff at this year’s Mix:

Learn how Web developers can use “M”, a new language for describing data, metadata and domain specific languages, to enhance RESTful services like HTTP, JSON, RSS/Atom, and more. Also see how “M” can be used on premise or in the cloud to achieve greater development productivity and to create more compelling customer experiences.

Come one, come all!

Martin, who has recently agreed to be the keynote speaker for the DSL DevCon, has a nice piece on DSL migration strategies.

While Oslo has no direct support for the incremental migration strategy to migrate DSL documents forward, we absolutely provide the tools for building it yourself. We do have very nice support for model-based migration, which keeps a parser around for each version of the DSL and produces the same underlying semantic model (which we call MGraph).

Stephen has three more installments in his series on modeling an application in Oslo: Discovery, Domain Entities and Refactoring and Transforming MGraph to TSQL. It's fascinating to watch him use the platform starting from scratch. Recommended!

Stephen’s been turning himself into an Oslo programmer:

″Telerik is building some cool Oslo utilities and I am in the middle of designing them. As I was talking to Chris about some of the specs the other day, he asked me: “What are you using to keep track of the metadata of your application in your design process?” I was like: “Pen, paper, whiteboard, Word and Excel.” He said why are you not using Oslo? Then it struck me, I was in .NET programmer mode. So last decade. While I am using Visual Studio 2008, WPF, SQL Server 2008 and the Oslo SDK to build an application for Oslo, I was not using Oslo to help build the application.”

Worth watching.
