A la comunitat local de Python en Castelló de la Plana: aquest divendres dia 28 a les 7:30 ens reunirem al local de Nayar Systems en Avinguda Casalduch, 9. Parlarem de Cat2Cloud ☁️ : ironarray.io/cat2cloud Com que és Black Friday, tenim un regalet preparat per als asistents! 🎁 Us esperem!

Downloading big data is not only boring, but also consumes immense resources. Handle and extract value right where your data is! 💚

It's Friday, and apparently bluesky is ready for this fun revelation: Dinosaurs lived on the other side the Galaxy.

I've built a demo Jupyter notebook that connects to a Cat2Cloud server from an Android phone and slices into an 8 TB dataset, downloading a 1 MB chunk in under 100 milliseconds. ⚡ Interact with your vasts remote datasets right in your phone! cat2.cloud/demo/roots/@... #Cat2Cloud #Blosc2 #BigData

ironArray is on a roll 🚅! With Cat2Cloud released this week we continue our 💊ironPill series with another video, showing you how to browse your cloud-hosted data ☁️ in the bespoke web client! Visualise and manage all kinds of data formats - from arrays to jpgs 🖼️, markdown to PDFs 📄 !

Yay! 🥳

So happy to see the beast out of the cage! 🥳

Stop downloading. Start computing. Everything changes on November 18, 2025. #Cat2Cloud is coming.

Haha, this from the New Yorker is getting passed around the math dork community. I did a comic about this kind of thought a few years ago: www.smbc-comics.com/comic/commut...

Our Blosc2 tutorial for @euroscipy.bsky.social 2025 is up! Learn how compression boosts tensor data handling, sharing & computing. www.youtube.com/watch?v=BdpT... #DataScience #BigData #HPC #OpenSource

📢🚨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! #Compute #Tensor #PyTorch

The importance of linear algebra in modern computing is undeniable 📐. Equally crucial is vertical integration. When SSD storage, memory hierarchies, compression, and computation are seamlessly orchestrated 💃, the performance gains can be transformative. 🚀

From a programmer's virtue to a computational powerhouse: laziness transforms a developer's best practice into the engine of modern computing.

Inspired by the ESA's Gaia Milky Way map 🌌! At SciPy 2023, we showcased visualizing a massive 7.3 TB Gaia dataset on a standard laptop by compressing it to 1.8 GB using #Blosc2. Big data analysis for everyone! 🚀 Dataset: digistorage.es/links/652403... Paper: www.blosc.org/docs/Explori... #napari

That's great news! Blosc2 is on its way to become a standard computing engine for most common array containers out there 🚀 Thanks to the array API standard effort; without it we could not possible reach this level of generality 🙏 Compress Better, Compute Faster

It's surprising how often the powerful SIMD capabilities of modern processors are overlooked. Harnessing them is key to unlocking next-level performance.

🎉 Exciting news! Python-Blosc2 is making huge strides towards array-api compliance. 🚀 From its humble beginnings in 2010 as a compressor for PyTables, it has evolved into a powerful n-dimensional container. 💪 There's more to come, but what a fantastic milestone! ✨

🗣️ Announcing C-Blosc2 2.21.2 This is a maintenance release, with a few fixes and some optimizations. Thanks to Barak Ugav and Preeyan Parmar. For more info, see the release notes in: github.com/Blosc/c-blos... Compress Better, Compute Bigger Enjoy!

LLMs are getting quite good at producing code. But when that last drop of performance counts, it seems our carbon-based predecessors 🧠, armed with good tools and a healthy obsession, still have a few tricks up their sleeves.

This is exactly the kind of application we envisioned for Blosc2, enabling more efficient and scalable data handling (in this case, image handling).

The slides of my talk about _Blosc2: Compress Better, Compute Bigger_ for the recent @euroscipy.bsky.social: www.blosc.org/docs/2025-Eu... EuroSciPy 2025 was great! A human sized event with lots of interesting talks and people ready to help you. Thanks to the organizers for such a fantastic event!

🚀 I'm also thrilled about the new blosc2.TreeStore class 🚀 We had the opportunity to show it in action during our recent tutorial at #EuroSciPy 2025, where we had a good time seeing audience engagement. Thanks to the attendees!

There's a special joy in deleting code. This Caterva2 release included a huge refactoring effort to shed complexity, resulting in a much cleaner and more robust system. It's one of the most satisfying parts of the job! ✨

Hey fam 👋 In a new blog post, I wrote about my journey from zero to RAG engineer after 1200 hours building enterprise AI. What actually works vs. what's just hype. Hard-learned lessons so you don't repeat my mistakes 👇 news.ycombinator.com/item?id=4474... #TechBlog #BuildInPublic #RAG #AI #LLM

While we've poured lots of ❤️ into #Blosc2 internal algorithms, every use case is unique. No worries! You can always tweak the internal knobs to get the best performance for your needs 💪
