OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Nginx Double A

A primitive Double A (AAA-minus-Accounting) RBAC system implemented in declarative Nginx config.

Background

So I noticed https://github.com/alexaandru/elastic_guardian, a simple AAA reverse-proxy to sit in front of Elasticsearch. Reading the source and comments tickled my "why is this in code not config?" funnybone.

I asked @alexaandru (https://twitter.com/jpluscplusm/status/438339557906735104) who told me it was mostly the resulting complexity of the nginx config he tried that prompted him to write it.

1. Create a docker-compose.yml

version: '2.1'

services:

  localstack:
    image: atlassianlabs/localstack:0.5.0
    ports:

kubectl multi-version brews

Applicability

The instructions below apply to older versions of Homebrew which still provide switch capability.

For current Homebrew, you'll likely need to keep Versions around, and build locally. Here's my versions repository https://github.com/rdump/homebrew-versions

MacPorts is now keeping versioned installations available as well, by default.

AWS ParallelCluster + AWS Batch

Today I'm going to demonstrate running High Performance Conjucate Grandients (HPCG) in a containerized workload. This takes advantage of AWS ParallelCluster, AWS Batch, and OpenMPI.

First install aws-parallelcluster:

$ pip install aws-parallelcluster

	Script to import multiple directories with textile files into Confluence Wikis. Can be used with OnDemand instances.
