The code you can hear! 18. TJUG birthday 18 September 2026 Municipal Culture Institute / Bistro Miasto, Cancer Fair 11, Gdańsk Java User Group turns 18! On this occasion we invite you to the event in two parts. In the afternoon we meet at practical workshops combining Java with music, and in the evening we celebrate the age of TJUG at the lighting of talcs, cake and conversations. Whether you have been with TJUG for years, or it will be your first meeting — stop by!
PART I: Workshop “The code you can hear! ” 14:00–17:30 ⏱ Workshop time: about 3 hours Limit: 15 people Municipal Culture Institute, Rakowy Market 11, Gdansk What happens below when you press “Play”? Why does the simple reproduction of the sound "something works", but its precise rendering requires a completely different approach to time? And what does Java have to do with this? During practical workshops you will build your own player and a simple audio engine. We start by playing the MIDI file, and then look deeper and see what is actually happening during the rendering of the sound and how this process can be improved. Slide minimum, maximum coding. The workshops are aimed at people who know Java on a medium-advance level who want to go beyond a typical backend and see how Java copes with time-consuming audio processing. The workshops are held as part of Music Jam: music. pl. Warsztaty requires separate registration. Signing up for 18. TJUG's birthday does not mean enrolling in a workshop. Records: musicjam.pl What should I prepare?
