Basic Git workflow

The Git workflow you will be using is as follows:

Fork the repository to your GitHub account.
Clone the project on your machine.

Basic RESTful API with Symfony 2 + FOSRestBundle (JSON format only) + FOSUserBundle + FOSOauthServerBundle

The API we are creating in this gist will follow these rules :

The API only returns JSON responses
All API routes require authentication
Authentication is handled via OAuth2 with password Grant Type only (no need for Authorization pages and such).
API versioning is managed via a subdomain (e.g. v1.api.example.com)

The API will be written in PHP with the Symfony 2 framework. The following SF2 bundles are used :

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Design rules

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)

Set variables in .bashrc file

don't forget to change your path correctly!

export GOPATH=$HOME/golang export GOROOT=/usr/local/opt/go/libexec export PATH=$PATH:$GOPATH/bin export PATH=$PATH:$GOROOT/bin

Set variables in .zshrc file

If you are using NGINX:

sudo apt-get update
sudo apt-get install software-properties-common
sudo add-apt-repository universe
sudo add-apt-repository ppa:certbot/certbot
Execute sudo apt-get update again
sudo apt-get install certbot python-certbot-nginx
sudo certbot --nginx

Q. Write a Rust Program

1. define a custom datatype using Struct with your favorite name. Which contains 3 fields, and 1 should be String Type.
1. In main function:
- A. Create an instance of the above defined struct
- B. Print complete instance
- C. Print instance by calling its fields.
- D. create another instance by using fields of first instance
1. define user defined function, User defined function should receive some arguments and return an instance of your above defined struct.
1. in main function call user defined function, Print instance returned by the user defined function.
