Lambda Container Images were announced at re:Invent 2020, providing a new way to build and deploy Lambda functions. They arrived just in time to solve an annoying build problem for me, so got my attention. And there weren’t any tutorials floating around when I first Googled, so I figured it was worth writing one. But … Read More
If you’ve ever done anything in Android that takes more than 16 milliseconds to process then you’ve probably heard of Android services and background processing in general. Why 16 milliseconds? At Android’s refresh rate of 60 frames per second, the main thread can not be delayed by more than 16 milliseconds to avoid frame skipping … Read More
When you’re planning to develop a mobile app the second most important decision you’ll ever make is selecting a technology to use (first being the content of the app) Ideally you’d want a version of your app for both iOS and Android and so there are really only 3 choices you have in 2021: 1. … Read More
Cypress is a relatively new web testing tool that is easier to use than Selenium, and it’s gaining in popularity. But using it in a continuous integration environment like AWS CodeBuild requires some additional steps compared to running it directly on your own computer. This blog post contains helpful information to configure CodeBuild on AWS … Read More
This post is a “deep dive” on the architectural decisions, and operational concerns, and simple mechanics of triggering a Lambda from an S3 upload.
How to send information to Lambdas by passing parameters and path-based variables to functions, and locking down functions from unauthorized access.
We’ll take a look at a cloud-based application platform, Serverless, and what it takes to get a simple function hosted on Amazon Web Services (aws), including configuring security with Amazon Cognito, and a front-end client with Angular.
In the following examples, I’ll show how to renew certs with domains hosted on AWS/Route53 and GoDaddy. I run certbot with scripts within a docker container (to simplify automation), however you can use CLI.
My last post compared different infrastructure tools for creating users and letting them assume roles for cross-account access. I received a few questions about the underlying problem that those scripts were trying to solve, so this post delves a bit deeper into the realm of user management.
We’ll walk through the process of creating an Android app that can preview 3D-printed sculpture in augmented reality (AR) against a real-time background, and perhaps discover something along the way about what rests at the intersection of art and technology.
