in UNIX OSes, chmod is a command to change files and directories permissions.
chmod stands for “change mode”.
one of the most important reasons for Linux to be on the list of safe OSes is that every user has their own permission for each file and folder.
Most web applications are implemented based on Rest Full APIs and as I researched huge part of them are not implemented based on best practices and clean code principles, so I decided to collect some points in a couple of posts to help make them more efficient APIs and Applications.
Let’s Look at other kinds of APIs
you can easily research and find out more about all of these kine of API design methodologies but here I’m going to just collect best part of them to create a document to implement Rest API in best practice.
Graphql
the best part of graphql is that you can design your API for the front end to just get whatever need, not more.
it can bring us better speed because less amount of packets is transferring over the network.

What is Docker?
This article is for you if you …
If you are a developer and you are going to start working with docker, and you already don’t know even the concepts of Docker, this article series is for you.
It was a little confusing for me when I started working with docker, so I decided to publish some articles for bits of help who are beginners to Docker or who want to review the concepts.
Overview of docker
Docker allows users to build independent and isolated development environments in the computer and run their software in a way that we call Container. For example, suppose you need a project with php8.1, but you only have php7.4 on your system(you need the php7.4 version to develop other projects).
In this use case, you can build a docker image that contains your PHP suitable version and your database and other environments and run it as a container by the side of another project in an isolated environment.
Another Docker use case
You are running a Linux environment with different PHP, database, composer, node.js, npm, and…
And your teammate is working on mac os with a completely different environment .
What is the solution?
How can you work on the same project simultaneously in a different environment?
How to deploy a project if the server can’t provide project requirements based on our development environment?
- docker can solve this problem by build isolated environments in the server and provide exactly requirements of peject in the isolated space.
