Upgrading to Ruby 2.1, Rails 4.0, Bootstrap 3.0

We at RedMart migrated our platform from EC2 to VPC on AWS. This is an outline of how we went about doing it.

This document describes an old and new development workflow for code reviews and continuous integration. The old workflow involved directly committing code to a shared master branch and deploying to a development server, while the new workflow uses feature branches, pull requests, and local virtual environments for development. It also introduces CIBox, an open source project that provides tools and automation to implement the new workflow, including provisioning a CI server and setting up initial project files.

This document discusses building a real-time (RT) image using Yocto Project. It provides an overview of Yocto and real-time Linux options like PREEMPT_RT and Xenomai. It describes extending Yocto recipes and layers to add support for building RT kernels and images for hardware like Raspberry Pi that can run real-time applications. The document references resources for the Yocto meta-xenomai layer and using Xenomai with Yocto to build real-time enabled embedded Linux images.

This document discusses setting up a shared development environment for a team. It recommends using GruntJS, a JavaScript task runner, to integrate common development tools like Bower, Compass, CoffeeScript, and livereload across Windows, Linux and Mac operating systems. The document outlines initializing a project with these tools, testing it, and deploying it with tasks for minification, concatenation, cleaning files and copying to production. It provides configuration examples for Gruntfile.js and links to a GitHub repository with an integrated HTML5 template project using these tools.

his talk is about tools and mechanism we developed and used to improve productivity and teamwork in our team (of 6 currently) while developing 70+ operators for Airflow over more than 6 months. We developed an "Airflow Breeze" simplified development environment which cuts down the time to become productive Apache Airflow developer from days to minutes. It is part of Airflow Improvement Proposals: AIP-10 Multi-layered and multi-stage official Airflow image AIP-7 Simplified development workflow

1. There are 13 ways to launch an app to the internet including using a local machine with port forwarding, a local machine in an office with ngrok or localtunnel, a dedicated server with SFTP or SSH, cloud storage services, git-based static hosting, serverless technologies like AWS Lambda, and container/cluster-based options like Docker swarm, AWS EBS, and Kubernetes. 2. Each option has varying degrees of ease of setup, ease of deployment, scalability, and suitability for frontend versus backend apps. Local development options are easiest to setup but not production ready, while container/cluster options are more complex but very scalable and production ready. 3. The document provides a
