I've written before about Agile and how we do it (not like other folks) and how I agree it can play well with CMMI. Even with that background, I was a little taken aback to read the title of this Scott Ambler blog post. But he makes an interesting case. He says at level 1 you're doing core Agile things. Maybe you're using Scrum, XP, Agile Modeling, or Agile Data. You're on the way. At level 2, you're disciplined Agile. I might phrase this as saying there's process in your agility and agility in your process. He lists some processes that build on Scrum and XP to provide a little more structure while staying lean. Then at level 3 you've achieved agility at scale. That really is a tough one - a small team with a small customer base has a much easier time being agile today. Perhaps it's a mythical level, or perhaps some folks are operating there.
I'm going to keep reading what Scott has to say on this. It's increasing my own comfort level with what to call our own approach to software development and problem solving.

I love this story. Seems a fellow was playing a low-stakes slot machine. This thing takes pennies, so if you win the "big jackpot" it doesn't rain pennies on you, it displays a message that says "you have won $xyz, please call an attendant over to this machine so you can collect" or words to that effect. Imagine his delight when it told him he had won 42.9 million dollars! Sadly, when the attendant arrived there was no 43 million dollar payout. The most that machine can pay out is $9,025.
So what happened? Here's the quote from the story:
In a confusing nutshell: Computers speak in a language of bits. Information is represented with zeros and ones. Very often, these numbers – both positive and negative – are stored in 32-bit sequences.
Still with me?
In this system, the number —1 can also be represented as 4294967295. Count that many pennies as dollars and you see 42,949,672.95.
The reporter wants you to know this is difficult. I want you to know it's hilarious. But then again, I didn't write a 43 million dollar signed/unsigned bug.

Toronto Code Camp is happening again this year, and this year I will be there speaking. My session title wasn't deliberately chosen to show up first in the list of sessions, I promise. The talk is:
Boost Developer Productivity: Write Extensions to Visual Studio
Visual Studio is a complex tool used by a wide variety of developers. Customizing your tool makes you more productive, and Visual Studio is highly extensible. In this demo-heavy session you will see how to write your own Code Snippets, how to write and use macros, how to write a simple add-in, and how to create your own templates for projects and project items, complete with wizards. Streamline development to fit your processes and habits by writing a little code to ensure that Visual Studio works the way you do.
I hope you already know the rules of Code Camp: all code, no fluff, and always free. Come on out and learn!

Women in Leadership & Technology, a subgroup of IAMCP Canada held their first Canadian “Meet & Mingle” on March 9th. It was a networking opportunity for women in technology and leadership both inside and outside Microsoft. This was a nice opportunity to meet some new people for me and to talk about the issue that seems never to go away ... why do so few other women want to be in this business? Maxine Chung from itbusiness.ca was there too and has posted a slideshow (I am not in any of the pictures though) that includes a summary, plus a longer article. Check it out!

Whenever a new OS or major application is released, there's a gap between when people want to start interacting with the functionality and when the .NET Framework supports that interaction. That's only natural - the framework release cycles aren't synced to the OS release cycles. This happened before with Vista, and is happening now with Windows 7. For Vista developers, the Vista Bridge provides easy access from managed code to the fun stuff like Restart and Recovery, Task Dialog, Power Awareness and so on. Stay tuned for announcements about a similar library for Windows 7. In the meantime some slightly more granular wrappers are available for you to use now, covering Taskbar, Libraries, Sensors, and Multi-Touch. Alon's blog has the details and the links.

If you see the things that go around the internet that everyone's seen, then you've probably seen the list of things you should have seen by now, but maybe not? A neat way to see how many of the memes you've picked up. Me, I'm kind of an old fogey at this stuff, but there are a dozen or so here that I have indeed seen (thus saving me, I hope, from being a loser or old or something). Have you?

Most of the developers I know think of SQL Server Express as something you use while you're developing, if that's simpler than getting a full SQL onto your developer machine. They naturally assume that when you want to go into production, or if you want to use some of the higher-end features, you'll need to buy a license of SQL rather than deploying to SQL Express. Well, you may want to, but you may not have to. For example, you can use Reporting Services with SQL Express. That surprised me. The details on what sets Express apart are at http://www.microsoft.com/sqlserver/2008/en/us/editions-compare.aspx and http://www.microsoft.com/sqlserver/2008/en/us/editions.aspx. Worth a read for sure and SQL Express is a valid choice in many data situations where you need a free product, such as distributing with your own applications or for low volume, low budget projects.

Here is an interesting video featuring Kevlin Henney (a confident speaker I've seen at SD West before) discussing some philosphy around good and bad OO design. I don't agree with everything he's saying, but I sure am glad he's saying it. The examples are in Java but that will hardly kill you. Worth a watch.
