In a busy developer's day, it's easy to take all the technology we build upon for granted. Who has time to think about DNS lookups, debounce on the physical keyboard button, or how the CPU prioritises tasks when the product owner wants their blue button right this instant?

This talk is a fun exploration of the fundamentals powering our digital world, taking us step-by-step through the journey of a simple action: typing https://devoxx.pl/ in your browser. We'll trace the entire process—from the electrical circuit activated in your keyboard, through DNS lookups and TLS handshakes, to the final instructions reaching your graphics card. Rather than diving deeply into any single technology, we'll follow the complete path across all layers of abstraction that developers typically take for granted, offering a refreshing perspective on the complex systems we build upon every day.
