TechDays Finland - Architectural Patterns for the Cloud - NuGet
As promised, here are the slide decks for the two sessions delivered at TechDays Finland last week. The promise of all cloud vendors out there is they can run your applications without changes. While that claim is true, it’s better to optimize existing software or design specifically for the cloud when moving or building an application. Architectural optimization will speed up your application, make it more scalable and even will make it cheaper to run on Windows Azure. This session will take you along some common patterns that are easy to implement and will make your cloud more sunny.

Introducing MyGet package source proxy (beta)
My blog already has quite the number of blog posts around MyGet, our NuGet-as-a-Service solution which my colleague Xavier and I are running. There are a lot of reasons to host your own personal NuGet feed (such as protecting your intellectual property or only adding approved packages to the feed, but there’s many more as you can <plug>read in our book</plug>). We’ve added support for another scenario: MyGet now supports proxying remote feeds.

Slides for TechDays Belgium 2012: SignalR
It was the last session on the last day of TechDays 2012 so I was expecting almost nobody to show up. Still, a packed room came to have a look at how to make the web realtime using SignalR. Thanks for joining and for being very cooperative during the demos! As promised, here are the slides. You can also find the demo code here: SignalR. Code, not toothpaste - TechDays Belgium 2012.zip (2.74 mb) A recording on Channel9 is available as well. PS: The book on NuGet (Pro NuGet) which I mentioned can be (pre)ordered on Amazon.

Tracking API usage with Google Analytics
So you have an API. Congratulations! You should have one. But how do you track who uses it, what client software they use and so on? You may be logging API calls yourself. You may be relying on services like Apigee.com who make you pay (for a great service, though!). Being cheap, we thought about another approach for MyGet. We’re already using Google Analytics to track pageviews and so on, why not use Google Analytics for tracking API calls as well? Meet GoogleAnalyticsTracker. It is a three-classes assembly which allows you to track requests from within C# to Google Analytics. Go and fork this thing and add out-of-the-box support for WCF Web API, Nancy or even “plain old” WCF or ASMX!

Don’t brag about your Visual Studio achievements! (yet?)
The Channel 9 folks seem to have released the first beta of their Visual Studio Achievements project. The idea of Visual Studio Achievements is pretty awesome: Bring Some Game To Your Code! A software engineer’s glory so often goes unnoticed. Attention seems to come either when there are bugs or when the final project ships. But rarely is a developer appreciated for all the nuances and subtleties of a piece of code–and all the heroics it took to write it. With Visual Studio Achievements Beta, your talents are recognized as you perform various coding feats, unlock achievements and earn badges. Find the announcement here and the beta from the Visual Studio Gallery here.

How do you synchronize a million to-do lists?
Not this question, but a similar one, has been asked by one of our customers. An interesting question, isn’t it? Wait. It gets more interesting. I’ll sketch a fake scenario that’s similar to our customer’s question. Imagine you are building mobile applications to manage a simple to-do list. This software is available on Android, iPhone, iPad, Windows Phone 7 and via a web browser. One day, the decision to share to-do lists has been made. Me and my wife should be able to share one to-do list between us, having an up-to-date version of the list on every device we grant access to this to-do list. Now imagine there are a million of those groups, where every partner in the sync relationship has the latest version of the list on his device. In often a disconnected world. How would you solve this?

Predictions for the future
It’s almost the end of 2011. Typically a time where bloggers start to write about their past year and what they’ll do in the next. A time where the Forrester, Gartner and McKinsey-alikes make predictions about next year. I know, normally I blog about technology in its technological sense, but today I feel like blogging about my vision on the future. Not 2012, but the future. And the present. Here’s my story in which I try to capture todays world and how this will influence technology.

Using SignalR to broadcast a slide deck
Last week, I’ve discussed Techniques for real-time client-server communication on the web (SignalR to the rescue). We’ve seen that when building web applications, you often face the fact that HTTP, the foundation of the web, is a request/response protocol. A client issues a request, a server handles this request and sends back a response. All the time, with no relation between the first request and subsequent requests. Also, since it’s request-based, there is no way to send messages from the server to the client without having the client create a request first.

Repaving your PC: the easier way
It"’s been a while since I had to repave my laptop. I have a Windows Home Server (WHS) at home which images my PC almost daily and allows restoring it to a given point in time in less than 30 minutes. Which is awesome! And which is how I usually “restore” my PC into a stable state. Over the past year some hardware changes have been made of which the most noteworthy is the replacement of the existing hard drive with an SSD. A great addition, and it was easy to restore as well: swap the disks and restore the image from WHS. SSD and full system install? 30 minutes.
