A developer shares personal gratitude for the software tools that shaped their career and workflow. Highlights include Go (chosen in 2015 over Node.js, credited with deepening systems programming knowledge), Redis (valued for its data-structure-centric flexibility), SQLite (praised for simplicity and zero operational overhead), Git and code-sharing platforms, and elementary OS (appreciated as a Linux distro with macOS-like polish). The IP and UDP RFCs are also mentioned as foundational reading.
