System Design Thinking Guide

1. Requirements Gathering

Clarify the requirements: Ask clarifying questions to understand both functional and non-functional requirements. This will help ensure that you focus on the correct aspects of the system.
- Functional Requirements: Core features (e.g., upload a file, search for a user).
- Non-functional Requirements: Scalability, performance, latency, availability, consistency, and security.
Example Questions:
- What’s the expected user base? How many daily active users?
Is there a focus on low-latency or high throughput?

Logrotate Configuration with Systemd Timer

This document explains how to set up logrotate to manage log files more frequently using a systemd timer. This approach is useful for log files that grow rapidly and need to be rotated more often than the daily rotation typically provided by cron jobs.

Logrotate Configuration

First, set up the logrotate configuration for your specific log file. Create a file in /etc/logrotate.d/ for your application. Here is an example configuration that rotates a log file when it reaches a certain size:

First, set up the logrotate configuration for your specific log file. Create a file in /etc/logrotate.d/ for your application. Here is an example configuration that rotates a log file when it reaches a certain size:

	#!/bin/bash

	# Ask the user to select a container
	echo "Enter the number of the container you want to bash into:"
	read container_number

	#!/bin/bash

	# Size of each log message
	LOG_MESSAGE_SIZE=100000

	# Function to rapidly log messages
	function log_messages {
	for i in {1..100000}; do

	LOG_MESSAGE=$(head -c "$LOG_MESSAGE_SIZE" /dev/urandom \| tr -dc 'A-Za-z0-9')

	#!/usr/bin/bash

	echo "Reloading systemd daemon..."
	sudo systemctl daemon-reload

	echo "Enabling and starting the logrotate timer..."
	sudo systemctl enable --now log_size_check.timer
