TOON (Token-Oriented Object Notation)

Token-Oriented Object Notation (TOON) is a compact data format designed to reduce token usage when passing structured information to Large Language Models (LLMs), achieving 30-60% fewer tokens compared to standard JSON. 

It simplifies syntax by eliminating unnecessary punctuation and using a more readable structure, making it ideal for applications that frequently interact with LLMs

Example:

JSON:  (41 Token)

{
  "users": [
    { "id": 1, "name": "Alice", "role": "admin" },
    { "id": 2, "name": "Bob", "role": "user" }
  ]
}

TOON: (21 token)

users[2]{id,name,role}:
  1,Alice,admin
  2,Bob,user

Convert jpeg file to pdf

Step 1 - Installa the following package

    sudo apt install imagemagick

Step 2 - Use the following command:

    convert *.jpeg my_pdf.pdf 


The command above might yield an “operation not allowed” error. Fortunately, we
can easily fix it by executing:

sudo sed -i 's/^.*policy.*coder.*none.*PDF.\*//' /etc/ImageMagick-6/policy.xml

or better:

sudo gedit /etc/ImageMagick-6/policy.xml

add or change the row at end of the file (just before </policymap>) with the following:

<policy domain="coder" rights="read | write" pattern="PDF" />

Ho to remove metadata from a PDF

 sudo apt install mat2

mat2 filename.pdf  # you will now end up with a file called filename.cleaned.pdf

mat2 --inplace filename.pdf  # this will overwrite original file with the new one, effectively removing the original file

mat2 --show filename.pdf  # this will show the metadata that will be removed, if any (similar to dry run) 

Bash GUI for QPDF (using Python)

 

Step 1: Create a python program called mergePDF.py

import PySimpleGUIQt as sg
import sys
import os 

arg = sys.argv[1:] 

current_working_directory = os.getcwd() + "/undefined.pdf"
current_working_directory = "/home/max/Scrivania" + "/undefined.pdf"


class Listbox(sg.Listbox):

    else: item = ""    
    return item

    if item:
       pos = mylist.index(item)
       newpos = pos-1
       if newpos>-1:
          mylist.insert(

window.close()
  

Step 2:  create a bash file mergePDF.sh to run the mergePDF.py

#!/bin/bash
python3 /home/max/batfile/Py/mergePDF.py "$@"
  

where /home/max/batfile/Py/ is the path where your python file is stored

Step 3:  create a link of mergePDF.sh file into scripts folder

    in my case into /home/max/.local/share/nautilus/scripts
