Want to use VS Code on a Raspberry Pi to code in Python? Here's how to do it.…

Read MoreI've been playing with a Raspberry Pi for a while, and I'm getting fed up with changing the input to my monitor and using a second keyboard/mouse (yeah, yeah, 1st World Problem I know). I decided to set up a remote screen share so I can share the screen. This means I can use the same monitor/keyboard/mouse that I use for my Mac, but it also means I…
Read MoreXamarin and Xamarin.Forms need no introduction. I'm sure by now you are well aware of these technologies and have seen many examples of building cross-platform mobile apps using C#. If not, I can highly recommend my book Xamarin in Action which if you follow this link and use code 'xamarininaction' you can get 40% off the cover price.What you many…

Read MoreI created a NuGet package a while ago to allow you to run models exported from the Azure Custom Vision service on iOS and Android in Xamarin apps from your cross-platform code. You can read about this here. Since then, the Custom Vision service has added ONNX export, meaning you can now run these models on-device on Windows as well. This meant it…
Read MoreRecently I wrote about creating AI models using the Azure Custom Vision Service. In these posts I looked at creating and training models, running them online, then finally exporting the models to run on iOS using CoreML and Android using TensorFlow. Recently Microsoft announced another way to export models - as ONNX models that can be run using Win…
Read MoreI spend most of my developer day using Visual Studio for Mac, but occasionally I flip back to Visual Studio 2017 on Windows. Last time I flipped back I tried to build an app that uses the camera and I got stuck on one simple thing - setting the camera usage description. If you double click on the info.plist file in an iOS app project, it will open…
Read MoreI've been playing a lot with F# recently, both to build Xamarin apps using Elmish.XamarinForms and for some Azure Functions. Whilst building an HTTP trigger I came across some weirdness when serializing a record type to JSON. This is the relevant parts of my code: type Output = { TotalBalance : float } let Run(req: HttpRequestMessage, boundTable: I…
Read MoreFinally, after 2 years since I first put pen to paper (well, put keystroke to Atom), Xamarin in Action is done and available from your favorite bookseller as a printed, paper book, with a forward from my good friend, the amazing James Montemagno! You can buy this book in one of two ways - an eBook in PDF, kindle, iBook format, or a printed book. If…
Read MoreTL;DR - check out Xamarin Essentials in the official documentation. Like a lot of developers, I love how Xamarin allows me to share business logic between iOS and Android apps, and share UI using Forms, but still have access to the native APIs. But one thing has been missing - a consistent, out of the box way of accessing native APIs from cross-pla…
Read MoreFSharp and Xamarin Xamarin is well known for allowing you to build mobile apps in C#, but you can use F# as well. F# is fully supported by the compiler and toolchains in both Visual Studio 2017 and Visual Studio for Mac. It's also pretty much supported by all the Xamarin tools including Xamarin.Forms (except for one bug that should be fixed soon).…

These are engineers who constantly work to make the world amazing for developers across a wide range…
Read MoreRecently I've been playing with a lot AI and seeing how it can be used in mobile apps to enhance the experience offered to the user. Currently I am playing with facial recognition using the Azure Cognitive Services Face API. This is a stupidly powerful API that can do a LOT of different things: Detect faces in images Analyze those faces to detect c…
