Meet our speaker Jonathan Striebel He will give a talk about the journey of Zaar, from implementation to ecosystem More info and tickets: euroscipy.org/2023/ #EuroScipy2023 #Basel

If you use Zarr, and especially if performance is important to you, then please could you spare a few minutes to describe your use-case in this thread: github.com/zarr-developer… This will help us to design performance benchmarks that are relevant for your use-case!

The main conference at #EuroSciPy2023 has started! Looking forward to many interesting talks and posters today 🧑‍🏫 PS come to the lightning talks later today, surprises alert! ⚡️

Jonathan Striebel is discussing Zarr and its evolution from a Python implementation to a thriving ecosystem in recent years. Zarr is an API and data storage format for n-dimensional arrays. #EuroSciPy2023 #zarr

Such an amazing experience to be an ambassador for zarr_dev at EuroSciPy today, and meeting other Zarr contributors like Isaac Virshup in person! Huge thanks to Sanket Verma, Josh Moore and AIGNOSTICS for the support! #EuroSciPy2023

I've been working on revamping zarrita.js recently... - ✅ Supports zarr_dev v2 and v3 (w/ sharding!) - ⚡ Runs in browser, Node.js, Deno - 🔧 Configurable compression & storage - 🦺 Typed with TypeScript GitHub: github.com/manzt/zarrita.… Docs: manzt.github.io/zarrita.js/

OME-Zarr is in Nature again, and #1 on Hacker News 🔬🚀! Congrats Jason Swedlow & Josh Moore nature.com/articles/d4158… news.ycombinator.com/item?id=377373…

Last night, ZEP2 (sharding for zarr_dev) was accepted by the implementation and steering councils. Thanks to everybody for contributing to the spec, providing helpful feedback and participating in the voting process! github.com/zarr-developer… 1/4

Hi Zarrites! 👋🏻 🎉 We've something exciting to share! 🎉 The ZEP0002 (Sharding) proposal has been officially accepted by the steering and implementation council. 🥂 Another win for zarr_dev's ZEP (buff.ly/3MphEeA) Process! 💪🏻 Thanks a lot, everyone! 🙏🏻

We merged my most wanted scikit-learn feature: a pair of estimators to modify the decision threshold of a binary classifier. Nice use case: tinyurl.com/5exejdz5; and avoid some traps: tinyurl.com/3cxm89s8. Thanks to all reviewers and contributors.

How intuitive can we make zk-VM implementations? 🤔 At the amazing ETHBerlin04, I teamed up with Valentin Pinkau and Jonathan Striebel to write a Python library for building zk-VMs, building on powdr labs! This is an example VM, with 3 general registers, 4 instructions, and memory 🚀

Do you use Xarray in a field outside the Earth Sciences? If so, we WANT to hear from you in our 2024 User Survey: forms.gle/X73jTQVmWxB14x…. Our current sampling is pretty skewed!

On my way to #EuroPython2024 in Prague 🐍 Looking forward to meet fellow Pythonistas, learn new stuff, and to give a talk together with Valentin Nieper 🎉 "Profile, Optimize, Repeat: One Core Is All You Need™" Thanks a ton AIGNOSTICS for supporting me on this journey! 💪

#EuroPython2024 was a blast! 🚀🐍 Valentin Pinkau and I gave a talk about profiling and optimizations for data engineering, code and slides are available at github.com/jstriebel/prof… Thanks to all the organizers, volunteers and speakers for this amazing conference! EuroPython

I BEG everyone to watch Łukasz Langa moved to 🦋‘s EuroPython 2024 Keynote. It’s not only an impressive musical performance and a ton of fun to watch, but it also demonstrates WHY free-threaded Python is such a HUGE deal. youtube.com/watch?v=dK6HGc…

🐍💥Python 3.13.0 has been released! 🎉 This is the first version with 🧵experimental GIL-free mode, an experimental JIT compiler🔧, a slick new REPL 🖌️ and many new cool features! And it's faster, smarter, and more colorful than ever! 🚀 Get it here: python.org/downloads/rele…
