McMaster University Library is proud to host DeltaHacks V this year in H.G. Thode Library of Science and Engineering. Spread over two days (Jan. 26-27), DeltaHacks is McMaster's annual student hackathon. This year, DeltaHacks hopes "to inspire students to hack for positive changes that align with their passions - whether it's environment, health, inequality, education, etc. And hence the name “delta” - as “Δ” stands for change."
