Format and tracks
The event runs five days across a dozen tracks: development, data science and AI, infrastructure, security, open source, product, UX, management, soft skills, maker and retro computing, general science, and a kids program.
About 70 percent of the Nerdearla audience reads or works in English daily, and roughly a fifth are decision makers at the lead, manager or founder level.
"Nerdearla exists to put technical knowledge within reach of anyone who wants it, whatever their budget," said Ariel Jolo, founder of Nerdearla and Sysarmy. "We have kept the conference free for twelve years, and we will keep it free as we expand into new markets, including the United States. Every talk, workshop and recording stays open at no cost, and we would welcome U.S. participants this September."
