Numba can make UDFs really shine ✨✨✨
🚨 Double threat!: Blosc2 3.12.2 + Caterva2 2025.12.3 release!🚨

✅ Streamlined computation for LazyUDFs
✅ Upload LazyUDFs for server-side execution in Caterva2

And as another consequence, Numba can now be integrated into your Blosc2 LazyUDF workflow very easily!

Blosc2 is making its way towards becoming a general array library for data that is in memory, on disk or remote. This will be extremely useful to add flexibility to our cat2cloud SaaS service: ironarray.io/cat2cloud 🚀 🎉
📢🚨Blosc2 3.11.0 Released! 🚨 📢

Blosc2 is part of the NumPy array library ecosystem: numpy.org

In v3.11, Blosc2 has become even more flexible; all functions can accept basically any array object:

𝚋𝚕𝚘𝚜𝚌𝟸.𝚖𝚊𝚝𝚖𝚞𝚕(𝙰, 𝙱)

for 𝙰, 𝙱 PyTorch, Jax, Tensorflow, Zarr... arrays!

It's surprising how often the powerful SIMD capabilities of modern processors are overlooked. Harnessing them is key to unlocking next-level performance.
🚀 Boost your Python computations on NumPy arrays with @blosc.jit! Let Blosc2's compute engine accelerate your code without changing containers. ⚡

For ultimate speed, native Blosc2 containers are still king. 🏎️

📣 #Caterva2 2025.8.7 is out! 🚀

We did a major refactoring for a simpler, more robust system, with client APIs unaffected. ✅

The highlight is the new cat2agent 🤖, a CLI client to watch a directory and auto-sync it with a Caterva2 server.

In this chapter, our Luke Shaw explains how filters work in Caterva2, a free software that you can run on your own laptop (or server, if you are more serious about large datasets). It works for either #Blosc2 or #HDF5 datasets.

Have it a try!

#WebGUI #DataAnalysis #LargeData
Caterva2 also supports filtering 🗃️data with fields, via the web client 🌐 or programmatically from Python code 🐍- even the most advanced queries are possible!
This makes it ideal for structured datasets for Data Science 🧪. See 👀 what Caterva2 can do !-> ironarray.io/caterva2.
