I’ve released another Xamarin NuGet package. This one provides a collection of tools that I use in every Xamarin project that I create - a base view, base viewmodel, along with some converters, and tools.
Two fun little projects I did recently. The first, I made a LCD screen showing stats from my fish tank using an Arduino and an AWS Lambda function. The second, my SNES broke so I replaced the internals with a Rasberry Pi.
I’ve released a Xamarin plugin on Nuget that provides a way to take users to the settings page for your application for iOS and Android. This can be useful if users have declined permissions and now need to go to the settings page to manually enable these permissions.
Xamarin invited Magenic’s mobile lead, Kevin Ford, to be a guest speaker at Magenic University to present the Xamarin vs Phone Gap White Paper that Kevin Ford, Ken Ross, and I created. Watch a recording of it on YouTube below.
I have a client with a Xamarin Forms app that streams live video for sporting events that they host throughout the year. Recently they sent me an email apologizing but saying they forgot to update a sponsor’s logo for an upcoming event. The event was 2 days away, could we get the app updated and in the stores?
I told them the truth. Most likely, no, but we can try. Here is the timeline of how we made it happen.
When you’re using AVPlayer with Xamarin one of the difficulties can be troubleshooting. There’s an easy way to get error notification from AVPlayer that isn’t mentioned in the Xamarin documentation.
You probably already have something similiar to this line:
Kevin Ford, Ken Ross, and I built an application twice (source code available at GitHub.com/Magenic/WhitepaperPerformance) once in Xamarin and once in PhoneGap. The white paper discusses the pros and cons of each platform as well as the performance metrics we saw from each when hitting the same Azure back end.

On Monday, February 23rd, Abbey Gwayambadde will be leading a session on Cordova development inside Visual Studio 2013. Sign up here:
The following Monday, March 2nd, I’ll be leading a workshop for anyone who’d like to try out Cordova development:
Microsoft Alpharetta Office 1125 Sanctuary Pkwy, Suite 300 Alpharetta, GA
Monday, March 2nd, 2015 at 7pm
Come on out and I’ll help you get your Cordova app up and running!
I gave a talk at GGMUG tonight on creating Android and iOS applications using the Microsoft Visual Studio Multi-Device Hybrid Apps framework.
Here is the source code for the application we made during the talk:
And here is the Power Point deck:
Thanks to everyone that came out!
While setting up a new team member to run a WPF app locally we ran into an error. It look about 30 minutes to realize our setup SQL script was creating a user in SQL server, but mixed mode authentication was not turned on.
To prevent having to relearn this problem again in the future we’ve added this code to our SQL script, right before the CREATE LOGIN command.
If you need to revert to a previous ClickOnce version you are expected to redeploy that older version.
Recently I was in a situation where this wouldn’t work as there were checked in code changes that the environment was not ready for. Now I could have reverted to the previous version in TFS and then redeployed that. But luckily I found an easier way.
Here is my solution to the latest code contest from The Daily WTF Programming Praxis: Josephus’ Circle.
What I like about this solution is that it represents in code, how the problem is actually carried out in real life. The soldiers are counted off one by one.
This recent post on The DailyWTF has brought in many comments with people providing code samples in many different languages. The post, Programming Praxis: Russian Peasant Multiplication, offers a simple coding challenge.
The challenge screams for recursion and many of the answers in the comments went this route. Of course, when we talk recursion we always have to qualify it as saying there is a performance penalty for using recursion.
Using this Russian Multiplication challenge as an example, I’ve done some testing to see how much the penalty is.

When creating ASP pages you can choose to use a number of scripting languages, such as VBScript, JScript, PerlScript, and even Python. While this may seem all fine and good, realize that VBScript, the most popular server-side scripting languages, is a watered-down version of VisualBasic. Think of VBScript as VB-Lite - certain things are missing.
