A Keep It Simple Stupid "ncurse disk usage" utility.
So very efficient

As it says : an initializer that will include all dependencies and setup a java spring project

So easy and usefull :
watch kubectl get pods

by default watch will launch the command and update the screen every 2 seconds.

The more I write docs / papers the more I use markdown the more I feel the need for a good markdown editor.
Typora is quite popular and has most of the functionalities I need.

New software for quick screenshots
Excellent

NGINX as a front end reverse proxy for docker containers

I want to destroy all my images AND all my containers (bye bye EVERYTHING, be warned). This is DEFINITIVE.

    #!/bin/bash
    # Delete all containers
    docker rm $(docker ps -a -q)
    # Delete all images
    docker rmi $(docker images -q)

I have this use case : one folder, many projects inside that folder, each of which depend on one another.
Sometimes, I want to pull everything. hence this very quick script , which does a git pull on all subfolder in the current folder.

git_pull.all.sh :

find .  -maxdepth 1 -type d -exec git --git-dir={}/.git --work-tree=$PWD/{} pull origin master \;

Quick & dirty test of mastodon api

require 'mastodon'
require 'oauth2'
require 'fileutils'

    APP_NAME = "tcmasto"
    SCOPE = "read write follow"

## INITIALISATION

def init

    url = "your_domain_url"  # exemple : https://framapiaf.org
    tcmasto_client = Mastodon::REST::Client.new(base_url: url)
    tcmasto_app = tcmasto_client.create_app( APP_NAME, "urn:ietf:wg:oauth:2.0:oob", SCOPE)

 oauth_client = OAuth2::Client.new(    tcmasto_app.client_id,
                                       tcmasto_app.client_secret,
                                       site: url)

  email = "yourmail@whatever.com"
  password= "yourpassword"

  token = oauth_client.password.get_token(email, password, scope: SCOPE)

  return {
      "url" => url,
      "client_id" => tcmasto_app.client_id,
      "client_secret" => tcmasto_app.client_secret,
      "email" => email,
      "access_token" => token.token
  }
end
