Blosc Development TeamJust took the new engine in Python-Blosc2 4.0 for a spin, and the performance results are quite awesome. Processing a 400 MB array:
🔹 NumPy baseline: 146 ms
🔹 Blosc2 (on NumPy arrays): 73.1 ms (2x faster)
🔹 Blosc2 (on native Blosc2 arrays): 15.1 ms (**9.6x faster!**) 🤯
The best part? It fully supports NumPy's array and ufunc interfaces. High performance with zero friction! 🏎️💨

HabrВсе об устройстве Q65 с примерами на Python (часть 3)
Q65 — цифровой протокол, разработанный Джо Тейлором (K1JT) и его командой в 2021 году для проведения минимальных связей в условиях сложных трасс прохождения радиосигнала. В предыдущих частях цикла были рассмотрены структура протокола, алгоритмы формирования сигнала, механизмы компенсации эффекта Доплера, синхронизация и детектирование сигнала в условиях быстрых затуханий сигналов. В этой части статьи рассматривается механизм декодирования данных Q-ary Repeat Accumulation кодов протокола Q65. Статья может быть интересна радиолюбителям, людям, интересующимся темой цифровой обработки сигналов и кодами коррекции ошибок.
Future CodingThis Python snippet shows how to draw a chessboard using NumPy and Matplotlib. The code creates an 8x8 matrix with alternating 0 and 1 values to represent black and white squares, then visualizes it using imshow. It demonstrates how simple array operations can generate patterns and how Matplotlib can convert data into visual output, which is useful for data visualization, simulations, and computer vision experiments.

IT World Cup (@itworldcup@hachyderm.io)
#ITWorldCup Greetings, programs 💾 I've got the honor to present you the match you all have been waiting for: The final of the 2025* Programming Languages World Cup: #python vs. #rustlang *yes, yes I know, but we started in 2025. Will start the next one earlier, so it doesn't get confusing again. [ ] Python [ ] Rust
Risto A. PajuFollowing my recent 2D image morphing demos, I've been thinking of visualizing the process as a single 3D shape. Since it starts with pixelated images, a voxel approach seemed the most straightforward.
While I wasn't quite happy with the blocky look, the parallel columns of voxels caught my attention, and they became a key stylistic element; they reminded me of the "fibre optic" mineral ulexite. I imagined carving a sculpture of such a fibrous material. So I replaced the piecewise columns by these long tubes.

I was able to pull a dataset from my local weather station and generate a simple 3d plot wit #pandas #numpy and #matplotlib to show the number of days in a year for a given temperature bin.
This is really helpful to find the sweet spot for a new #warmepumpe installation
Towards Data ScienceReduce the complexity of your RAG pipeline. Thomas Reid shows how #NumPy and SciKit-Learn can often replace a dedicated vector database for small-to-medium scale projects, saving you time and resources.

From a pile of shit, new life grows. Conway's Game of Life running independently in the 3 colour channels in 64x64 cells with wrap-around topology.
Not much new code here, just added image loading capability to my old pile-up demo of 2D cellular automata.
