Featured Jim Bennett Technology, vscode, automator

I've been getting fed up with the long winded process to open things in VS Code - you know, typing in the terminal, opening VS Code and dragging folders in, that sort of long, manual process... #FirstWorldProblems 😜 I thought it would be fun to automate the whole thing, using Automator!

Featured Jim Bennett Technology, xamarin, google play, appcenter, firebase

I've been working on an app that needs push notifications, but also needs to be open source. This led me to a problem - the google-services.json file. This file is needed to sign up for Firebase messaging to implement push on Android, but it also contains my API keys, values I do NOT want to be public. So - what to do? Well I'm building and distr…
