The author reflects on how exciting programming can be, especially when it solves real problems like creating virtual desktops that run inside web pages and letting them work smoothly even on lowâpower machines. They then describe a personal project: an iTunesâstyle playlist manager that uses ffmpeg (and soxâs BPM counter) to change song tempos for workout music, allowing the tempo to increase gradually and testing new BPM values such as 165âŻbpm. The tool started as a bash script, evolved into a Node.js CLI with subcommands that open a browser UI for easier playlist management, and the author contemplates adding dynamic BPM adjustments (e.g., alternating between 140 and 170âŻbpm) or even turning it into a small business where users submit nonâcopyrighted tracks or use a hardware button to speed them up. All of this showcases their enthusiasm for programming and the fun of building custom applications that blend creative ideas with practical functionality.
