3 ways to build a GitHub Action with Dart

In 2020, I published the Pub package github_actions_toolkit to write GitHub Actions with Dart more easily. However, GitHub Actions runners don't support natively the Dart language, and some steps are necessary to execute a Dart program in a GitHub Actions workflow.

Below I compare three ways to create a GitHub Action with Dart, with their pros and cons.

Postfix, Dovecot, MySQL – Ex Ratione

This long post contains a recipe for building a reasonably secure Ubuntu 16.04 mail server in Amazon Web Services, using Postfix, Dovecot, and MySQL, with anti-spam packages in the form of amavisd-new, Clam AntiVirus, SpamAssassin, and Postgrey. Local users [are virtual][1] rather than being system users. Administration of users and domains is achieved through the Postfix Admin web interface. Webmail is provided by Roundcube.

This is an updated version of earlier [Ubuntu 12.04][2] and [Ubuntu 14.04][3] mailserver recipes. A number of people graciously helped to fix bugs and make improvements in the original, so should you find a blocking issue here please do let me know.

Introduction

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

Create the file with the environment variables:

$ cat envs.txt
HOSTNAME=app.domain.com
PASSWORD=foobar

Create the config map:

In this procedure, we are attempting to set up a devnet, which is a blockchain completely local to your machine. Below is the attempted procedure to get it up and running.

In general, believe this is the structure we want:

 lighthouse1[Lighthouse consensus client]

  home: '/',
  login: '/login',
