What the @ - fixing weirdness in return JSON from Azure functions using F#

Featured Jim Bennett 19 Jun 2018 fsharp, f#, azure, functions, technology

I'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…

Face identification with Azure FaceAPI

Recently 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 FaceAPI. This is a stupidly powerful API that can do a LOT of different things: Detect faces in images Analyze those faces to detect ch…

Identifying my daughters toys using AI - Part 5, Plugin for on-device models

Featured Jim Bennett 26 Feb 2018 xamarin, xamarin.ios, xamarin.android, xamarin.forms, Tensorflow, AI, CoreML, nuget, custom vision, cognitive services, azure, technology

In the first part of this series I used the Azure Custom Vision service to create an image classifier to allow me to easily identify my daughters cuddly toys. Once created I tested it by uploading an image and seeing what tags the classifier found for the image. In the second part I accessed this model from a Xamarin app, so that I could use the ca…

Identifying my daughters toys using AI - Part 2, using the model

Featured Jim Bennett 02 Jan 2018 azure, cognitive services, technology, xamarin, xamarin.forms, Porg, custom vision

In the first part of this post I used the Azure Custom Vision service to create an image classifier to allow me to easily identify my daughters cuddly toys. Once created I tested it by uploading an image and seeing what tags the classifier found for the image. Although this works, it's a long winded way of using the model. Ideally I'd want it in a…

Hiding API keys from Git

Featured Jim Bennett 28 Dec 2017 azure, technology, api, keys

I've been working on a Xamarin app using Azure Cognitive Services to do image recognition, and one of the stumbling blocks I've faced is what to do with my API keys. I want to make the app open source as an example of how to use these services, but don't want to check my API keys into Git to be available to all - after all, bad things can happen. I…

Prefer to watch instead of read? - https://youtu.be/3sjInlJcpBs It's currently just after Christmas, and my 4 year old daughter has received a fair few cuddly toys from Santa. These bring her total collection up to way too many, and like most parents I have a hard time remembering all their names, especially the least favorite ones that rarely come…

Getting a users Facebook profile after Authenticating your Xamarin app with Azure

Featured Jim Bennett 17 Nov 2017 xamarin, xamarin.forms, technology, azure, facebook, authentication, functions

I've recently been looking at the authentication offered by Azure for use in a mobile app, specifically using social auth providers like Facebook to allow a user to sign up for my app. The auth setup is incredibly easy, with Azure taking care of a lot of the hard stuff. There are also loads of great docs on how to get it set up - including the Micr…
