Hacktoberfest 2019 Poznań Meetup

Let's hack for Open Source together

About Hacktoberfest

Hacktoberfest is an annual event across all of GitHub which is meant to encourage developers to contribute to open source projects.

As a couple of guys amazed by open source projects, we decided to organise a meetup for this event in Poznań.

Whether it's your first step in open source or you already maintain your major project for several years, join us and let's hack for Hacktoberfest together.

The event consists of two main tracks. You are free to attend only one of them, or both - whichever you find more interesting!


A place to plop down with a laptop and write some code. Meet new people, ask for help, help others, talk about cool projects, share your knowledge, socialize! (Or don't. It's up to you - just have fun!)


Talks about Free Software, Open Source, programming, and IT in general.

What is Hacktoberfest?
Hacktoberfest is an initiative by DigitalOcean and DEV.to (website) and it's all about contributing to open source projects. After submitting 4 contributions you'll get a limited edtition Hacktoberfest 2019 T-Shirt. You can pick any project of your interest but all of the contributions must be accepted within October.
Why are we doing this meetup?
Because we can! We all share a common passion for open source. We consider it to be a very important idea. As such, it’s substantial to encourage new people to join the movement. And what better way could there possibly be?
Who can join?
Anyone interested in Software Development. It doesn’t matter if these are your first steps towards Open Source or if you are experienced Software Architect maintaining several projects. For beginners, we’re going to show how to proceed with Git and GitHub. For experienced people, we can offer a comfortable place with snacks to commit and contribute.
What's in it for me?
By contributing to Open Source, you’re helping everyone in the community. Additionally, as a person, you become more valuable on the market. We have a chance to give what we took from Wikipedia!
Which languages will be spoken during the event?
All of the event staff speaks English and Polish. Talks will be given either in English or in Polish, based on the speaker's preference (that said, we expect the majority to be in Polish).


Attendance is free. However, for organisational purposes, we ask you to kindly register for the meetup on Eventbrite.
This will help us estimate the number of attendees and fit the venue accordingly.
