Gaia Studio

This Docker container is build to provide very useful features

• Heartbeat (with cron)
  • every minute (cron)
• Web APIs
  • curl requests
• Web Browser
  • pdf generator (chromium)
  • screenshot generator (chromium)
• Databases
  • SQLite (local files)
  • SQL (remote SQL server by PHP PDO connections)

ARCHITECTURE

Gaia Studio is built on 2 main technologies

• Docker Containers
• PHP

Docker Containers

Docker containers are used to provide a very stable and portable environment.

• A docker container can work identically on Mac, Windows, Linux

• A docker container can start automatically at machine boot (daemon mode) A docker container can be deployes on the cloud and work as saas (Software As A Service)

• Docker containers are built on top of Linux

• Docker containers are very light

• Docker containers are very fast to start

• Docker containers are very fast to stop

• Docker containers are very fast to restart

• Docker containers are very fast to update

• Docker containers are very fast to deploy

• Docker containers are very fast to scale

• Docker containers are very fast to backup

• Docker containers are very fast to restore

• Docker containers are very fast to migrate

• Docker containers are very fast to monitor

• Docker containers are very fast to debug

• Docker containers are very fast to secure

• Docker containers are very fast to share

• Docker containers are very fast to ...

PHP

Inside the Docker container, the programming language is PHP. In the context of building an AI, the choice of the programming language is important. An AI is a program that can learn and adapt its code to the environment. If you choose a language that needs a compilation step, then your AI can produce a new version of the code. But it will need a step to recompile the code to run it. If you wan to remove this compilation step, then you need to choose a language that can be interpreted. PHP is an interpreted language. PHP is a very good choice for building an AI. PHP is originally a template engine, so it can generate PHP code easilly. And PHP can dynamically load PHP code, so it can adapt immediatly its code to the environment.

PHP on the web

Another good advantage of PHP is that it is used by +75% of the web sites. So the PHP code produced by Gaia can be used by +75% of the web sites. And WordPress is a CMS (Content Management System) that is built on top of PHP. So Gaia code can also ne integrated into WP as a plugin. WordPress is used by +40% of the web sites.

CRON

• With Alpine linux, the cron daemon is available as part of busybox.

Activity by every minute

• Heartbeat
• The basic period for a cron task is 1 minute.
• A cron task can last more than 1 minute

In the context of an AI working as a human developer, A human is expected to produce 1 line of code every minute. It seems so easy for an AI to produce 100 lines of code every minute. So a coding AI could be easily x100 more productive than a human developer ?!

SQL

SQL databases are very popular and efficient to store data. Docker allows to add a SQL MariaDB container very easily. SQLite a also a very light SQL database that can be used as a local file. SQLite has a web assembly version that can be run in the browser.

NGINX + PHP-FPM

• AI must be able to instrospect itself
• As the docker container is a web server,
  • then an incoming request should be able to re-launch some other recursive requests
  • problem: if using the PHP built-in web-server,
  • each request is blocking the others until finished
  • => impossible to have recursive requests

Chromium Headless

• https://developer.chrome.com/articles/new-headless/

• FIXME:

• Solved

  • chromium headless doesn't load ttf fonts ?!
    • add Alpine several font packages (ttf, emoji, ...)

chromium --headless --print-to-pdf https://applh.com

chrome --headless=new --print-to-pdf --no-pdf-header-footer https://developer.chrome.com/

* delay before print or screenshot
chrome --headless=new --print-to-pdf --timeout=5000 https://mathiasbynens.be/demo/time

chrome --headless=new --screenshot --window-size=412,892 https://developer.chrome.com/
