Contents of the meeting
At this meeting, we have three talks planned. If you read this and would like to give a talk at a future meeting too, please reach out to us!
Talk 1: Python and MongoDB, a perfect marriage
by Mathijs Gaastra
In this talk, Mathijs will share his experiences using Python with MongoDB, a popular NoSQL database. He will discuss the advantages of using MongoDB for certain types of applications, and how Python’s flexibility and ease of use make it a great fit for working with MongoDB.
Talk 2: Deploying Python apps to your own infra with Github Actions
by Michiel Beijen
Learn how to use Github Actions to deploy your Python applications to your own infrastructure. This talk will cover setting up CI/CD pipelines, managing secrets, and best practices for deployment. We’ll look at how to use self-hosted runners to make deployment super easy!
Talk 3: Identifying “blast beats” in music using Python
by Lino Mediavilla
Blast beats are a type of drum beat originating in hardcore punk and grindcore music, and are now commonly used in extreme metal genres such as death metal and black metal.
In this talk, Lino will discuss how he & his group of friends used Python to create the Blast Beat Counter to analyze audio recordings and identify instances of blast beats. This involves Python, spectogram analysis, beautiful visualizations and some music!
About our meetups
Our talks happen in a friendly and informal setting. They are a great way to learn new things, share your knowledge, and meet other Python enthusiasts. There is always room for questions and discussion. Our presentations and talks are in English to be accessible for the large amount of non-Dutch speakers in the Python community.
Price
The meetup is free of charge. Drinks are available for a small fee. We ask for a small donation to help cover small expenses, but this is not required.
