Obecné
- Na Pyvu jsou přednášky většinou česky, pokud přijde někdo, kdo česky nerozumí, přepneme do angličtiny, pokud se na to přednášející cítí.
- Kromě nealko a alko pití je možné se Na Věnečku najíst. Nabídka je proměnlivá a obvykle jde o 4 až 7 jídel od toastu, párků, přes bramborák se zelím, dršťkovou polévku a smažák v housce až po guláš nebo řízek.
- Nezapomeň s sebou vzít hotovost – neberou karty.
- Na Věnečku zavírají o půlnoci.
General
- Talks at Pyvo are mostly in Czech but it there’s somebody who doesn’t understand Czech talks are switched to English if the speaker is able to.
- Cash only payments – club doesn’t accept cards.
- Besides both soft drinks and beer it's possible to eat at the club. Choice is variable and consists of 4 to 7 options ranging from toast, sausages and soup to fried cheese in a bun, goulash or schnitzel.
- Club closes at midnight.
Talks
The Need for Speed: Pandas, Polars, and PySpark for Data Analysis
- Dalibor Trapl
Are you working with a dataset so large that your notebook running Pandas starts to freeze?
This talk is about modern alternatives for fast and scalable data analysis. Our main focus will be the Polars DataFrame library, which offers a dramatic speed improvement compared to Pandas. We will show when it pays off to use Polars instead of Pandas and discuss the key difference in approach: eager vs. lazy evaluation. We will briefly compare Polars with PySpark and I will share our experience integrating these technologies into our data pipelines. Learn how to speed up your data analysis and modernize your tech stack!
My burnout journey
- Peter Hozak
A story of a programmer who loves to solve meaningful user problems and thrives best around competent product managers - a story about distance from customers, corporate management fast fashion, and AI slop. Also about communities and going for a walk.

Venue
Na Věnečku, Ostrovského 38a, Praha 5, Czech Republic, 15000
Jedná se o soukromý klub, takže nikde není žádná cedule. Když Ostrovského ulice přejde v chodník se zábradlím po obou stranách, jděte 60 metrů do kopce. První brána po pravé straně je vchod do dvora. Ujděte ještě 40 metrů a vchod do klubu najdete vlevo.
It’s a private club with no public signs. After Ostrovského street becomes a footpath walk 60 meters uphill. Club is in the first gate to the right. Go 40 more meters and entrance to the club will be to your left.
