The heart of software

• Leaders within a team who understand the centrality of the domain can put their software project back on course.
• Software developer is like a researche, both have the responsability to tackle the messiness of the real world through complicated domain that has never been formalized.
• There are systematic ways of thinking that developers can employ to search for insight and produce effective models.

Ingredients of effective modeling

### Chapter 2: Creating and Destroying Objects

#### Item 1: Consider static factories instead of constructors
* An instance-controlled class is one that uses static factories to strictly control what instances exist at any time.

Persistent PostgreSQL inside Docker

source: https://crondev.com/persistent-postgresql-inside-docker/

Most recommended way to persist data inside docker is to create data only container. However to simplify things it is also possible just to mount a directory from the host and to use that location as persistent storage. Also, this way it is easy enough to dockerize existing Postgres installations.
For existing postgres installations here are some preparation steps (Ubuntu 14.04 with postgres 9.3):
Stop postgres if running:

sudo stop postgresql

Shell initialization files

3.1.1. System-wide configuration files

3.1.1.1. /etc/profile

When invoked interactively with the --login option or when invoked as sh, Bash reads the /etc/profile instructions. These usually set the shell variables PATH, USER, MAIL, HOSTNAME and HISTSIZE. On some systems, the umask value is configured in /etc/profile; on other systems this file holds pointers to other configuration files such as:

• /etc/inputrc, the system-wide Readline initialization file where you can configure the command line bell-style.

Refatorar é bom para aprender OO

Uncle Bob blogou no Clean Coder sobre uns code reviews que ele fez do código (e das refatorações) de um cara chamado John MacIntyre.

Uncle Bob criticou a conclusão do cara de que refatoração não vale a pena para projetos reais: refatoração é uma maneira efetiva de evitar que o código apodreça e fique difícil de manter.

O que achei de mais interessante sobre o post do Uncle Bob é que ele pegou o código inicial do cara e foi fazendo pequenas refatorações, no estilo Baby Steps. No final, acabou melhorando drasticamente a estrutura do código e tornando-o muito mais extensível. O exemplo é bem pequeno mas, mesmo assim, houve uma melhora significativa.
O código inicial:

frankrausch

#/bin/sh

speed="0.7"

mkdir "speed-${speed}x"

for f in *.mp3
  do ffmpeg -i "$f" -filter:a "atempo=${speed}" "./speed-${speed}x/$f"
done

Document stores in PostgreSQL

Notes for software engineering meeting presentation

What

• mid to late 2000s: appearance of Document stores / NoSQL databases such as Mongo, Couch
• Relational DBs now have support for document data: JSON in MySQL, JSON and JSONB in PostgreSQL
• Focus on JSONB in Postgres (most full featured)
