Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

How to use AWS Fargate and Lambda for long-running processes in a Serverless app

Build an ETL job service by fetching data from a public API endpoint and dumping it into an AWS Redshift database.

Published on Jan. 11th, 2018 at https://serverless.com/blog/serverless-application-for-long-running-process-fargate-lambda/

AWS dropped so many serverless announcements at re:Invent, the community is still scrambling to make sense of them all. This post is all about AWS Fargate.

In this article, I will show you how to create an end-to-end serverless application that extracts thumbnails from video files. But, oh no, processing video files is a long-running process! Whatever will we do?

Keyboard-only Mac Cheatsheet

Hi, I'm Lorna and I don't use a mouse. I have had RSI issues since a bad workstation setup at work in 2006. I've tried a number of extra hardware modifications but what works best for me is to use the keyboard and only the keyboard, so I'm in a good position and never reaching for anything else (except my coffee cup!). I rather unwisely took a job which required me to use a mac (I've been a linux user until now and also had the ability to choose my tools carefully) so here is my cheatsheet of the apps, tricks and keyboard shortcuts I'm using, mostly for my own reference. Since keyboard-only use is also great for productivity, you may also find some of these ideas useful, in which case at least something good has come of this :)

Apps List

There's more detail on a few of these apps but here is a quick overview of the tools I've installed and found helpful

Introduction

This is a Hashicorp Terraform module that provisions an AWS EC2 instance for the purpose of running a given docker-compose.yml file.

Usage

# ===== OUR MAGIC DOCKER-COMPOSE.YML FILE HERE =====
# It is also possible to get Terraform to read an external `docker-compose.yml`
# file and load it into this variable.
# We'll be showing off a demo nginx page.
