Dmytro Lytovchenko builds a live chiptune synthesizer in Erlang, turning notes into waveforms, PCM audio and real-time playback.

Series (one-dimensional) and dataframes (two-dimensional) for fast data exploration in Elixir

What breaks first in real-time messaging? How concurrency and architecture shape reliability in live platforms.
