Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

sgnl

Outdated note: the process is a lot easier now: after you brew install postgresql you can initialize or stop the daemon with these commands: brew services start postgresql or brew services stop postgresql.

new out put may look like

To have launchd start postgresql now and restart at login:
  brew services start postgresql
Or, if you don't want/need a background service you can just run:
  pg_ctl -D /usr/local/var/postgres start

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Nesse artigo vou mostrar rapidamente como tirar um Print Screen da página inicial de seu site utilizando diversos dispositivos. Algo que pode facilitar e muito a vida caso esteja desenvolvendo uma página responsiva.

Nesse exemplo vamos utilizar o NodeJS e o Selinium 2. As outras dependências necessárias estão especificadas no arquivo package.json. Arquivo que é usado para fornecer ao gerenciador de pacotes NPM informações de como lidar com as dependências do projeto, a descrição do projeto, a licença utilizada, dentre outras.

Para facilitar nossa vida vamos utilizar um serviço de Cloud do SauceLabs. Esse serviço permite utilizar diversos tipos de navegadores. Logo logo

Setup Mac OS X

I've done the same process every couple years since 2013 (Mountain Lion, Mavericks, High Sierra, Catalina) and I updated the Gist each time I've done it.

I kinda regret for not using something like Boxen (or anything similar) to automate the process, but TBH I only actually needed to these steps once every couple years...
