In this final post in the series on advanced Redux in Xamarin, we'll look at how to integrate a local database with Redux, we'll write Middleware that intercepts CRUD Actions and applies them to our database.Read Article
In this second post in the series on advanced Redux in Xamarin, we'll look at how to persist Actions so application state can be restored when the app restarts. We'll do this by creating Middleware that will intercept each action and save it to a persistent store, then rehydrate the application state from that store on app startup.Read Article
Redux is an implementation of the Flux architecture that manages UI changes through a single global State object that can only be mutated by dispatching Actions. It provides a way to easily reason about state changes and to share that state across multiple separated areas of the UI.
Recently my team have come up against this error a few times building a Xamarin app using Visual Studio 2017 both on the Mac and PC, and it took a bit to work out the fix.

First there came pair programming, a development disciple that promised team collaboration, improved quality, inbuilt mentoring and redundancy. Now the development community is taking it to the next level - mob programming. Mob programming, or mobbing, is where the entire team works together on a single problem, sharing one PC, one keyboard and one mouse.Read Article
Here’s a little promises quirk that I’ve overlooked for a while. Generally we all write promises like this:
doSomething() .then(doSomethingElse) .then(doSomethingFurther) .catch(handleError);

doSomething() call. If an exception is raised here it will be treated like a normal exception and stop executing all the rest of your code. So how do you deal with it?
Getting images into Google Slides is simple right, just upload the image and voila. What if instead of images you want icons? You can always take a screenshot of an icon and upload that, but then you’re stuck with the size because resizing that thing is going to make it ugly. There’s a better way.Read Article
For years I’ve used Wordpress to host my site, which has been great but it’s overkill for what I need. I’d be happier to write the HTML myself if it wasn’t such a maintenance pain keeping consistency across all the pages. I hated having to update WordPress continually to ensure my site is secure. In order to keep all my site source in Git I have to synchronise the changes that happen automatically on the server, like updates and uploads / media files back to my working copy to commit them. And it doesn’t enable me to keep any of my content in Git, which is most important, I have to take regular database backups for this.Read Article
