Hacktoberfest is a month-long event that encourages people to contribute to open source projects by fixing bugs, creating new features, or updating documentation. DigitalOcean and GitHub sponsor the event, which offers free t-shirts to participants who open four pull requests on any GitHub-hosted project. InfluxDB is also participating in Hacktoberfest, offering its own t-shirt and stickers to developers who contribute to its codebase during October. To participate, developers simply need to submit their details via email after opening two accepted pull requests against InfluxDB or Telegraf.
