Abstract: Make a database which can be store historic modification is often considered a “secondary” activity, but bad design leads to databases that are difficult to optimize and often not very understandable. In this article we illustrate a simple method that respects the dictates of relational theory & is easy to understand. As a plus we will show it on SQLite, a small but powerful database system.

On 2002, I was forced to build a small java class to “sync” two databases (sorry for Italian):
SmartSync used the Metadata offered by JDBC API to be able to copy data between two tables. In the last years I evolved it to be able to support a special use case called “dump to SQLite”.

Some news site still try in 2021 to disable right click and ability to copy content. These tactis are very very poor, and only block the users not interested in copying/stealing your code.
The idea is to put something like that on body tag:
<body oncopy="return false" oncut="return false" onpaste="return false" onbeforecopy="return false" ondragstart="return false" onselectstart="return false" oncontextmenu="return false">
The code to re-enable it is easy to find out:

The HP 42S accompanied me throughout my university career, secretly designed for me some function graphs and with its 7KB alphanumeric also managed to make me keep some secret notes.
I bought it on December 5, 1992, paying it 229,000 lire, a year before I started university (about 200€ now considering inflation * ).

In Microservices architecture, you decompose your services in a set of fine-grained services. These services are full-stack software, from front end API down to database layer.

Amazon Elastic Container services (ECS) is the Amazon Solution for running docker containers on Amazon.
ECS is not a docker swarm implementation. I am writing this article to stress this, because this point is not very clear digging in the tutorials (it is explained a bit in the question “What is the difference between Docker Swarm, Kubernetes, and Amazon ECS” but then the tuytorials mix the things up too much).

https://github.com/daitangio/misterioMisterio is a docker-compose based Ansible alternative.
Why
I need to show Ansible and Saltstack configuration manager are nice tools but in a K8s world, the same result can be achieved in a much simpler way.It was to teach the container way to some co-worker.Without effort, I end up with a tool I am using on my home machines, which include a bunch of very different architecture (Ubuntu Boxes, ARMs RPi2, Windooze).So I think it would be nice show Misterio to the world...and yes there is a bit of magic, called containers. -

I have a shiny mail server on gioorgi.com. I decided to manage it on first person because it is important to have tight control on your email, in my humble opinion.
