October is notable in the software development world due to Hacktoberfest, an event promoting contributions to open-source projects on GitHub, which has engaged the Brazilian community extensively. Developers from Brazil contribute daily, and notable companies and universities organize events to encourage participation. Highlighting the local involvement, the Hacktoberfest Recife, organized by Otacílio Maia, offered workshops for first-time contributors. The GitHub ¡Presente! event is also back, featuring the Egua programming language, developed in Portuguese by students from Belém do Pará, and is part of Hacktoberfest. The event, free and in Portuguese, is set for October 27 on Twitch, with speakers like Thayana Corrêa Mamoré, Hernandes, Lucas Pompeu Neves, André Eleutério, and Ruy Adorno. Further details and the complete program are available at github.co/presente.
