Session Goal

The session aimed to automate the streaming of radio stations using a Python script and various scheduling tools such as crontab and systemd.

Key Activities

• Used the rtcwake command to manage system wake-ups, ensuring all services are operational before task execution.
• Scheduled a daily cron job for the Python script at 8:50 AM.
• Explained the role of DISPLAY and XAUTHORITY variables for rtcwake command authorization.
• Created a systemd service to run the Python script without user login, focusing on security.
• Modified the open_radio.service file for dynamic URL configuration based on the day of the week.

Achievements

• Successfully automated radio streaming using Python and cron.
• Enhanced system automation with rtcwake and systemd configurations.
