Welcome to another installment of Counting Down to Seven, a series of articles about mobile app development that I’m writing as we count down the days to MIX10, when we reveal more about the up-and-coming Windows Phone 7 Series.
If you’re a developer itching to get started writing apps for Windows Phone 7, you’re going to want to follow Charlie Kindel’s blog and Twitter stream (as well as Yours Truly and this blog, of course). Charlie’s one of the developers on the Windows Phone team, and while he won’t be delivering the first presentation on WP7 at MIX10 (Windows Phone’s VP Program Management Joe Belfiore will do that), he’ll be delivering the first technical presentation later that day.
The video above shows an interview that’s as informal as it gets. It’s a hand-held camera interview featuring CNET’s Ina Fried and Charlie on the Embarcadero in San Francisco, talking about what Windows Phone 7 will be like for developers, with Charlie demonstrating on his Windows Phone 7 prototype. I’d love to get my grubby paws on one of those!
This Thursday, my fellow Developer Evangelist John Bristowe and I will host another live Ignite Your Coding webcast, where we’ll interview another high-profile software developer and pass along some of your questions.
This week’s guest is Glenn Block, a Program Manager for .NET FX at Microsoft. Glenn’s one of the go-to guys on Prism, Unity, MEF and ways of building maintainable and reconfigurable applications out of pieces that you can assemble and rearrange in general. We’ll talk with him about building composite applications, design patterns, the “alphabet soup” of SOLID, DI and IoC and whatever questions you ask him.
(We don’t have a photo of Glenn Block, but we do have the image to the right, which is the symbol for MEF – that’s Managed Extensibility Framework – which is one of Glenn’s projects. It’s a lucky coincidence that Glenn’s last name is also featured prominently in the image.)
If You Want to Catch the Live Webcast on Thursday and/or Ask Glenn Questions…
If You Want to Listen to a Recording of the Webcast Later…
We’ll make it available in MP3 format soon. Watch this site for details!
What’s Ignite Your Coding All About, Anyway?
It’s all about helping you, the software developer, find ways to stay on top of the technological, economic and social changes that affect you and your work every day. We got our hands on some of the biggest thinkers and doers in our field and asked them if they’d like to chat about the industry, how they got started, where they see the opportunities are, how they deal with change and how to be generally awesome. We got some big names from the Microsoft/.NET world, but we also went farther afield and got some people from beyond that world as well, because a different perspective is often helpful.
Welcome to another installment of Counting Down to Seven, a series of articles about mobile app development that I’m writing as we count down the days to MIX10, when we reveal more about the up-and-coming Windows Phone 7 Series.
We’re a week away from the start of the MIX10 conference! I like to refer to this as Microsoft’s most “right-brained” gathering, as its target audience and topic isn’t just developers and writing software, but designers, design and user experience.
With designers and design in mind, it’s only fitting that I show you a video featuring Nic Fillingham interviewing a couple of Microsoft User Experience gurus who also hail from Canada:
Bill Buxton: He’s a Principal Researcher for Microsoft Research, and before that, he was Chief Scientist at Alias Wavefront and a professor at University of Toronto. And I’m pleased to report that he got his bachelor’s degree – in music – from my alma mater, Crazy Go Nuts University (which some of you may know as Queen’s University). He was the guy who thought of applying Fitts’ Law to human-computer interaction, did some pioneering work with multi-touch interfaces and invented the pie menu (which means that we owe weapon selection in Saints Row 2 and the full combat/spellcasting system in Dragon Age: Origins to him).
Albert Shum: He’s the Director of Mobile Experience Design for Windows Phone 7. Albert’s from Winnipeg, studied engineering and architecture at University of Waterloo and went on to do design work at Nike before joining Microsoft. You can watch a video showing him talking about the new Windows Phone 7 experience and the thinking behind it in a previous article of mine, Albert Shum on Windows Phone 7.
This Week on Channel 9, or TWC9 for short, is a weekly digest show hosted by Microsoft’s Dan Fernandez and Brian Keller covering the developer community news they find most interesting after sifting through hundreds of blogs, videos and announcements. It’s aimed primarily at .NET developers, but if you have any geeky tendencies at all, chances are they’ll cover something that appeals to you!
This week’s episode is their 100th, and in it, they cover:
Topic
What it is or why it’s interesting
Second patch for IntelliSense crashes in the Visual Studio 2010 RC
The RC is the last public build prior to RTM. It’s pretty rock solid, but users of touch displays, tablet PCs, screen reader software, and potentially some others as well may need these patches.
If your projects use Silverlight 3 and you use Team Build on a 64-bit server, you’ll need this. But it’s also a good look at debugging a Team Build 2010 workflow.
Visual Studio 2010’s testing framework is extensible and will provide support for additional target platforms via add-ins from Microsoft and 3rd parties.
The diff / merge tool that ships with Visual Studio is fairly dated, but it’s easy to swap in your favorite tool in its place. This one is free, and comes highly recommended.
There are dozens of coding competitions out there at any given time, but we thought this one was really cool – you can either build a “mechanical Turk” game or an image recognition application. And c’mon… it’s Mars! That should be reason enough.
To give you the thesis of the article, here are the next two paragraphs in the article:
It doesn’t matter if you go running every morning, or you’re a regular at the gym. If you spend most of the rest of the day sitting — in your car, your office chair, on your sofa at home — you are putting yourself at increased risk of obesity, diabetes, heart disease, a variety of cancers and an early death. In other words, irrespective of whether you exercise vigorously, sitting for long periods is bad for you.
That, at least, is the conclusion of several recent studies. Indeed, if you consider only healthy people who exercise regularly, those who sit the most during the rest of the day have larger waists and worse profiles of blood pressure and blood sugar than those who sit less. Among people who sit in front of the television for more than three hours each day, those who exercise are as fat as those who don’t: sitting a lot appears to offset some of the benefits of jogging a lot.
There are two reasons that sitting all day is bad for you:
Sitting burns so few calories. Even standing in place burns more calories, what with the work your leg muscles do. Since weight gain is a slow, creeping thing, and little things like eating 30 more calories than you burn is enough to lead to 2 – 3 pounds of weight gain a year. 30 calories is a handful of potato chips!
Sitting causes your body to do things that are bad for you. When you sit for long periods, your body stops producing lipoprotein lipase, which is important for processing fats, and your metabolism slows down to match the inactivity.
If you’re self-employed, a mobile worker or have an understanding manager, you can take frequent breaks to do something out of your chair. As a Developer Evangelist with Microsoft, I’m a mobile worker and have taken advantage of the arrangement to do things like:
When working at the home office, taking the occasional break to run errands on foot or get some quick household chore done.
Going to the gym in the middle of the day, when it’s not crowded. An unexpected side-effect: many of my retired neighbours, who are at the gym in the middle of the day, think I’m sort of unemployed ne’er-do-well.
Switching venues: I try to work part of the day at the home office, and part of the day elsewhere, either a wifi-equipped cafe or HacklabTO. Many of these venue changes incorporate a bike ride anywhere from 10 to 30 minutes each way.
It’s worked out pretty well so far; since joining Microsoft, I’ve lost about 12 pounds.
But what if you’ve got an urgent project? Those interruptions are deadly to the sort of “flow” you need to get complex tasks done. One answer might be a “stand up” workstation, where the desk is mounted high enough so that you can use it in the standing position. A more extreme solution is the one pictured at the top of this article – yes, that things is real – Steelcase’s “Walkstation”, a workstation with integrated treadmill. Not only do you get some exercise while you work, the more poetic of you can treat it as an in-your-face metaphor for corporate life below the VP level.
Welcome to another installment of Counting Down to Seven, a series of articles about mobile app development that I’m writing as we count down the days to MIX10, when we reveal more about the up-and-coming Windows Phone 7 Series.
For the longest time, the sessions listed under “Windows Phone” at the MIX10 conference (taking place in Las Vegas from March 15th through 17th) have had no details – just a “more details coming soon” message. That changed yesterday, and now the sessions have full names and abstracts, which I’ve listed below in chronological order.
Major changes are coming to Windows Phone! This session goes in-depth on the design and features of Windows Phone and gives a comprehensive picture of what’s coming in this exciting new release.
The new Windows Phone is coming! Get a high-level overview of the new application platform and a complete picture of the developer story. Learn about the developer tools, the application frameworks, the support for Silverlight, and the support for XNA.
Joey’s note: Charlie isn’t exaggerating in his Twitter profile when he says that the future of application development for Windows Phones is in his hands.
Windows Phone constitutes a dramatic new user experience paradigm. This session will provide prescriptive guidance, tips, and techniques on how designers & developers can build beautiful, compelling user experiences that are consistent with the built-in Windows Phone 7 Series experiences.

The Mobile Web has been a long time in coming, and now that it’s here, it’s a force that you and your business can’t afford to ignore. What has made all of this possible is the combination of ever-more-powerful devices, fast network connections, and highly capable mobile browsers. In this session, you will learn how to build sites that work well and look great on Windows Phone and across mobile devices. We’ll cover the core mobile Web scenarios, preparing content for mobile, and tips and techniques for debugging and testing your sites.
Joey’s note: I would argue that the mobile web has been around for a couple of years now, but it’s nice to see it done properly on a Microsoft platform at long last.
Welcome to another installment of Counting Down to Seven, a series of articles about mobile app development that I’m writing as we count down the days to MIX10, when we reveal more about the up-and-coming Windows Phone 7 Series.
That’s Microsoft’s Eric Rudder, Senior VP Technical Strategy demoing Platformer at the TechEd Middle East conference. Not only does Platformer play on Windows Phone, Windows, XBox and Zune, but he also demoed saving the game state on the phone and resuming it from the saved state on an Xbox 360.
Eric also showed that even though Platformer runs on a number of platforms, it’s based on a single codebase with slight platform-specific tweaks for the platforms it targets. This isn’t new: XNA has been about targeting Windows and Xbox 360 from the very beginning, and with version 3.0, the Zune was added to the set of target platforms.
Take a look at this screenshot of the Solution Explorer from Visual Studio 2008 with XNA 3.1 with a Platformer solution loaded. Note how the solution has three projects, one each for targeting Windows. Xbox 360 and Zune:
All three games share the same sounds, but the Windows and Xbox 360 versions use a set of higher-resolution graphics while the Zune version uses a lower-resolution set.
XNA also makes use of compiler directives to handle the differences between platforms. For example, here’s a code snippet from Platformer from the Player class, which manages the player’s character in the game:
Note how the Zune version has scaled-down values of those used in the Windows and Xbox 360 versions. That’s to account for the Zune’s smaller screen.
XNA on Windows Phone 7, with the ability to save game state on one platform and resume playing on another opens up a world of “ubiquitous gaming” possibilities. I hope that this will bring about some interesting mobile games and bring some attention to the XNA, which I always felt was underappreciated.
If you’re a developer itching to get started writing apps for Windows Phone 7, you’re going to want to follow Charlie Kindel’s blog and Twitter stream (as well as Yours Truly and this blog, of course). Charlie’s one of the developers on the Windows Phone team, and while he won’t be delivering the first presentation on WP7 at MIX10 (Windows Phone’s VP Program Management Joe Belfiore will do that), he’ll be delivering the first technical presentation later that day.
