We also have 's-Hertogenbosch. Yes it starts with an apostrophe.

Thanks, Nathan!

Michael, thank you so much! It's great to hear that you like the book and it's much appreciated that you took the time to write such a generous review.

Now that the book is out, we're shifting our focus to spreading the word. Look for us at upcoming conferences, on podcasts, and more. Stay tuned!

We're also incredibly grateful to our technical reviewers, the Polars community, our colleagues from Xomnia and @posit.co, friends, and family; many of whom are listed in the acknowledgements.

We had the pleasure of collaborating with NVIDIA and @delltechnologies.bsky.social to benchmark Polars on the GPU. The results are documented in the appendix. Thank you Mark Cai, Irina Shekhovtsova, and Logan Lawler for making this possible.

Special thanks to Ritchie Vink, the creator of @pola.rs, for answering our countless questions, and for writing such a generous foreword.

A huge thank you to our amazing editors at @oreilly.bsky.social : Aaron Black for believing in this project, Sarah Grey for guiding us through the writing process, and Jonathon Owen for helping us cross the finish line.

Thijs and I have been pouring our hearts into this project for nearly two years, and it's surreal to finally see it on the shelves. Funny story: we don't have our own author copies yet because the book was apparently sold out (hence the picture at our local bookstore)!
