New Course! Architecting Applications with Visual Studio Team System (Bootcamp)

On March 17th in Toronto, I'll be teaching our first delivery of this new course. It's a one day hands on, instructor led - whirlwind bootcamp style course that gives you a lap around Visual Studio Team System - specifically with a Solution Architect's perspective. We touch a little bit on the project management stuff, testing and some of the developer tools, but primarily we'll spend more than half the day on modeling as we walk through the Whitehorse designers.

Now how can we teach a course on a product that's not even in beta you ask? Very carefully. A lot of people are evaluating if and how they'll use VSTS in their shops once it is released so by popular demand we're offering this course a little earlier than we would normally. This course probably needs to be 3 days to properly focus on best practices and true “architecture” but for the purposes of evaluating this technology and letting people make their own minds, we are focusing primarily on the tools provided. With that in mind, this abbreviated 1 day course is being delivered in 6 cities across Canada: Toronto, Montreal, Ottawa, Vancouver, Calgary and Quebec City. There is also a promotional price of $299 CAD. For more details, full schedule and registration, visit http://www.objectsharp.com/ttdinvitation/vstsbootcamp.aspx 

 

 

DevTeach June 18-22, Montreal and a $50.00 Rebate Code!

DevTeach is a really nice conference. I went to it for the first time last year and it's a very intimate and interactive conference. While smaller than your TechEd's and PDC's, it manages to attract a very good set of speakers....Kevin McNeish, Brian Noyes, Julia Lerman, Don Kiely, Patrick Hynds, Carl Franklins, Mario Cardinal, Ted Neward, Nick Landry, Etienne Tremblay, Sam Gentile, Jim Duffy, Guy Barrette, Eric Cote, Markus Egger, Kate Gregory and me too. I'll be doing a DataSet tips and tricks talk - but mostly just so I can get a free pass to go and see all the other great talks. This year it is being held once again in Montreal which is a beautiful city with a great night life.

And last but not least, here is a rebate code for $50.00 "TO000OBJSHARP". You can register at http://www.devteach.com

What are you doing for your summer job?

We have a very exciting internship project coming up this summer for a university student, perhaps co-op - but not mandatory.

This high-profile project is to develop a software system to monitor the various systems in a “green” home that is completely off of the power grid. The house is fed by batteries charged by solar and wind (and a backup generator). There are many other systems in place to optimize power usage throughout the house. Although this home is off the grid, it's not off the internet, so the software will have to publish it's information and allow remote access via it's 2-way satellite system. The software will also be developed in .NET, likely using the current whidbey beta.

You are a university student with some combination of electrical engineering and computer science. You are strong “quality-oriented” programmer. You have strong design skills and are good at listening and capturing requirement. The position will be located in southern ontario.

If you are interested, please send your resume to bgervin@Objectsharp.com .

.NET Celebrity Auction

Be a sport and click on this link:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5552696499

Then make a generous bid. If you'll win, you'll get an hour (or more) of help from a .NET guru/celebrity (or possibly me). But more, you'll also be helping Tsunami relief efforts.

The top bid gets to pick their consultant. Then next, and so on and so on. If you are in southern Ontario, and you get me, I'll make it up to you by coming to your office - for a whole day, hang out, and bring donuts. What will I do? I can tell you everything I know about Visual Studio Team System (breaking all kinds of NDA rules, etc.), try to convince you to use data sets, do some code reviews, help debug something nasty, defrag your hard drive, organize your mp3's, tell you what DataGrid girl is really like, whatever.

I'm visiting Vancouver, Calgary, Ottawa, Montreal over the next 3 months so if you live/work near there, my offer stands, pending my schedule. I'll also be in Orlando possibly in June (for TechEd), LA in Sept (for PDC), and Chicago in August, so ditto on those as well.

For more info on how it all works....

And finally, special thanks to the other RD's who are volunteering their time (especially all those fellow Canadians). Last but not least, special thanks to Stephen Forte and Julia Lerman for organizing this.

An Update on Whidbey/Yukon Release Dates

In case you missed it, in this article key microsoft executives are quoted as saying that Whidbey and Yukon are still slated to ship together but that won't be by end of June as earlier stated. They are now estimating that “summer” is a better statement of expected arrival. This may align itself nicely with the PDC 2005 September date. It sounds like both teams blame each other, but really, a lesson can be learned here for all of us: Cross product integration means longer delivery cycles. This is going to be a tough nut for our industry to crack moving forward, not just Microsoft. Is that what SOA promises?

SqlConnection woes on the Compact Framework over WiFi

Last night at the Toronto .NET Users Group talk I did on mobility, a gentleman had a question about directly connecting to an Enterprise SqlServer database from a Pocket PC using the Compact Framework. His users run on a shop floor and some times they lose their wifi signal. While he doesn't keep the SqlConnection open the whole time, it seems that when a wifi signal is back alive his application can't connect to the database using a SqlConnection.Open anymore - despite that he can still ping the server.

He was correctly doing a SqlConnection.Close in a finally clause around his data access, but I suspect that even though pooling is not supported on the compact framework, this is not doing a proper disconnect of the physical connection (a Sql Profiler session would probably tell you that for sure). So a using block in C# will ensure that the SqlConnection is disposed of immediately and will properly terminate the connection. So if between calls you lose and reaquire your wifi connection you'll be starting a bran new connection the next time. It's still a good idea to put all of your actual work in a try/catch/finally block with a SqlConnection Close in the finally.

using (SqlConnection cn = newSqlConnection(CONNECTION_STRING ))
{
 try
  {
   cn.Open();
   //do some work with the connection
  }
  catch (SqlException ex)
  {
   //error handling
  }
  finally 
  {
   cn.Close();
  }
}

Shorthorn Longhorn

So this will cause a few blogs. I have just heard that....

  • Longhorn slated for 2006. Longhorn server 2007.
  • Winfx, and Avalon are coming to windows xp in 2006. Indigo as well - and on Windows 2003 as well. These are all part of WinFx that is going to be extremely important for .NET developers and companies wanting to take advantage of these improvements.
  • Winfs is leaving longhorn (post release). So that means ObjectSpaces and the Microsoft Business Framework too.

Wow. Never a dull moment. I'm attending a briefing with Jim Allchin in an hour so I might have more I can tell.

But will we also see a delay of ObjectSpaces or the Microsoft Business Framework until after the longhorn release. Those have been recently tied into WinFs - but no specific announcements about that - and I wouldn't be surprised if that changed soon. 

DevCan 2004

I'm co-chairing two tracks of DevCan coming up in Setp/Oct in Vancover/Toronto (exact dates to follow) - see www.devcan.com for more.

I'm doing the architect track and web track. If you have ideas for content you'd like to see, or have a topic you'd like to present in either of those categories, send them to me. You don't have to be canadian, but it helps :)

Data Driven Development

So we have Test Driven Development and Model Driven Development or Design by Contract (similar perspective). But in the past, I've been a fan of Data Driven Development. This is a technique I haven't had the pleasure of using recently....because it relies on you building new applications with new databases.

What is this technique you ask? Well for me it is designing the data model first. In the early days of Client/Server, PowerBuilder and ERwin were my tools of choice. New applications. New databases. My design process (and that of many of my associates) was not so much to design a database but to document the data that existed in the organization - and do that in 3rd normal form. ERwin still stands as one of the best modeling tools ever because it actually made the job of coding up a database schema easier and faster than any other alternative. I could also use my model throughout the entire lifecycle since it did an excellent job at full round trip engineering/synchronization.

One of the cool features of PowerBuilder was your ability to annotate your database schema with UI hints. So you could say that a given column in your database should by default be shown as a checkbox, and that checked should be saved as “true“ and unchecked as “false“ - or whatever weird thing your DBA said it had to store. Whenever you designed a screen with that column, bam you'd have it the way you'd expect - as a checkbox. The downside of PowerBuilder's datawindows of course was that the data store/entity/container was quite pretty tied to your database and they made no attempts to hide that fact. But boy, productivity was really high - although I was producing tightly coupled, loosely coupled code :( .NET let's me build better code now, but productivity is still lacking.

At TechEd a couple of weeks ago, I stopped by the DeKlarit booth for a demo of their product by their lead architect Andres Aguiar. I was happy to see a tool that builds upon the Data Driven Development process. Of course, you don't have to start with an empty database, but this tool does an excellent job of making your job easy when starting from scratch. Andres promised to send me an eval so I can play with it some more to see how it works with existing databases but this tool so stay tuned. I could easily see this tool paying for itself in a matter of a couple of weeks.

As for ERwin, I'm still a fan although it really hasn't changed much in the past 10 years. I remember the first copy I had fit on a single floppy. So did the 200 table model I created with it. I was using LBMS System Designer who stored my model in some kind of 10mb black hole and took 10 minutes to generate a schema. When I first installed ERwin, I had it installed and reverse engineered by LBMS model - and forward engineered to from Oracle to SqlServer inside of 10 minutes. I couldn't believe the schema generation took 20 seconds compared to LBMS at 10 minutes.
