## Exponential Backoff: A Gentle Introduction

Think of exponential backoff like a polite person knocking on a door - they start with gentle knocks close together, but if no one answers, they wait longer and longer between each attempt.

### The Basic Concept

**Exponential backoff** is a retry strategy where the wait time between retry attempts grows exponentially (doubles, triples, or increases by some multiplier) after each failure.

### Simple Example

Imagine you're trying to call

SELECT column_name, data_type, data_length
  FROM all_tab_columns
 WHERE table_name = 'DFE_RECEBIMENTO'
   AND owner = 'MSAF_DFE'
 ORDER BY column_id;

PDF Page Remover - A script to remove specific pages from a PDF file.

Usage:
    python remove_pdf_pages.py input.pdf output.pdf page1 page2 page3 ...
    
    - input.pdf: Path to the input PDF file
    - output.pdf: Path to save the output PDF file
    - page1, page2, ...: Page numbers to remove (starting from 1)

Requirements:
    - PyPDF2 library (install with: pip install PyPDF2)
"""

import sys
import os
from PyPDF2 import PdfReader, PdfWriter

def remove_pages(

from PyPDF2 import PdfMerger, PdfReader
merger = PdfMerger()

pdfname1 = "pdfname1"  //pdf1 name
pdfname2 = "pdfname2"  //pdf2 name

merger.append(PdfReader(open(pdfname1 + ".pdf", 'rb')))
merger.append(PdfReader(open(pdfname2 + ".pdf", 'rb')))
merger.write("merged.pdf")

The `spec` parameter is a **powerful feature** that makes your mocks **safer and more realistic**. Let me explain with concrete examples.

## **What `spec` Does**

The `spec` parameter tells `Mock` **what attributes and methods** the mock object should have, based on a real class or object.

## **Without `spec` - Dangerous and Permissive**

```python
from unittest.mock import Mock

# Mock without spec - accepts ANYTHING
mock_engine = Mock()

# These all "work" even though they don'

# Install packages steamOS

## Configure package manager
If you have not already, use ```passwd``` to create a password for the deck user.

Disable read-only mode: ```sudo steamos-readonly disable```

Initialize the ```pacman``` keyring: ```sudo pacman-key --init```

Populate the ```pacman``` keyring with the default Arch Linux keys: 
```
sudo pacman-key --populate archlinux
sudo pacman-key --populate holo
```

Try installing a package: ```sudo pacman -S vim```
