Build Your Own Agentic Harness in Python - Full Tutorial This tutorial demonstrates how to build a custom AI agentic harness in pure Python by progressively integrating LLM communication, tool calling, and Model Context Protocol (MCP) support. It covers the full development loop from scratch, enabling persistent memory and model routing to create functional, autonomous agents. https://www.youtube.com/watch?v=H5o1P8RMiMw

Making a mathematical model for better Indic keyboards The article develops a mathematical model for more efficient Indic touchscreen keyboards, starting with Tamil and mapping script structure into Boolean logic and compact input states. It uses Python with SymPy to derive and simplify the logic, then implements the resulting input engine in TypeScript. https://triangulatedexistence.mataroa.blog/blog/making-a-mathematical-model-for-better-indic-keyboards/

Django: serve apple-app-site-association and assetlinks.json Django can serve the apple-app-site-association and assetlinks.json files needed for Apple Universal Links and Android App Links, letting installed apps securely claim website URLs and support password autofill and passkeys. The post walks through the required JSON, Django views, tests, caching, and production verification with Apple’s CDN and Google’s Digital Asset Links tools. https://adamj.eu/tech/2026/10/02/django-app-links/

How to Take a Website Screenshot with Python Vendor-authored Site-Shot tutorial: Python SDK, CSV batch captures, and a local HTML index. Requires a paid Site-Shot API plan. https://www.site-shot.com/blog/take-website-screenshot-with-python/

openTPU An open-source AI accelerator, developed by AI: RTL, ISA, simulator, compiler and profiler in one repo. Runs Qwen3, LFM2.5 and Qwen3.5 on a Kintex-7 PCIe card. https://github.com/FeSens/openTPU

Jev for Python engineers Vercel’s Python AI SDK adds support for Jev, a fast universal classifier that answers structured choice, scoring, and probability questions without task-specific training. The post tests Jev on classifying Python vs. English and generating Python ASTs, showing that it works well for narrow decisions but still struggles when pushed into general code generation. https://vercel.com/blog/jev-for-python-engineers

Python 3.15.0 https://www.python.org/downloads/release/python-3150/

8 Python 3.15 Features You Need to Know Python 3.15 introduces practical enhancements such as lazy imports, a built-in immutable dictionary, and streamlined unpacking in comprehensions. These updates, alongside a new sampling profiler and default UTF-8 encoding, aim to improve developer productivity and application performance. https://www.youtube.com/watch?v=bgeqL4Btou0

Can Jev save my inbox from the Democrats? The author outlines an end-to-end ML project evaluating whether TypeSafe’s Jev, accessed through OpenRouter, and smaller local models can effectively filter political fundraising emails from a personal inbox. He ultimately builds a 23.4 MB quantized ONNX SetFit model using mdbr-leaf-mt and confidence thresholding, creating a fast, CPU-friendly local classifier while exposing the remainin... https://huggingface.co/blog/stephen-solka/use-jev-to-delete-fundraising-emails

Pyronaut Pyronaut is a high-performance polyglot application platform that brings Micronaut features like HTTP routing, dependency injection, configuration, validation, and Java library access to Python via GraalPy. https://github.com/micronaut-projects/pyronaut

Build & Train a GLM-5.3-Flash Model From Scratch with Python This tutorial demonstrates how to build and train a compact 25-million parameter multimodal language model from scratch using modern techniques like mixture-of-experts and sparse attention. It further explores the AI researcher's role by guiding viewers through pre-training, reinforcement learning experiments, and the critical importance of designing effective data-driven environments. https://www.youtube.com/watch?v=-gfgQfw2g_E

The things you own end up owning you NumPy is being ported toward Python’s Limited API so it could eventually ship abi3 wheels that work across multiple Python versions, reducing the large per-version wheel matrix and easing support for new Python releases. The same work is also pushing NumPy toward subinterpreter support by replacing static types and global state with heap types and per-module state, though multiarray rema... https://labs.quansight.org/blog/limited_api_numpy

Orchestrating Disposable Browser Glazer replaced race-prone parallel startup with readiness signals between Python and Docker containers, allowing components to start concurrently without assuming that running means ready. That design cut cold starts from 8–10 seconds to about 4.5 seconds, and caching the Tor data directory brought startup down to a consistent 1.9–2.1 seconds. https://blog.glazer.ee/posts/building-glazer-disposable-browser/

AI Development on Windows: from PyTorch and llama.cpp to Windows ML Microsoft is expanding local AI development on Windows with experimental GGUF support in Windows ML via llama.cpp, new native inference APIs, and an OpenAI-compatible endpoint for running models locally. The broader stack also adds native PyTorch and Triton support on Windows Arm64, giving developers a path to train and optimize models with familiar tools and deploy them through Windows ... https://devblogs.microsoft.com/foundry-on-windows/build-on-winml-oct-7-26/

Building a Faster (Rust-Based) Python Driver for ScyllaDB ScyllaDB is building a new Python driver on top of its Rust driver using PyO3, with most serialization, deserialization, request execution, and concurrency handled in Rust for better performance and maintainability. Benchmarks show especially large gains under concurrent workloads, while the project still needs production hardening, broader feature coverage, and a compatibility layer for... https://www.scylladb.com/2026/09/28/building-a-faster-rust-based-python-driver/
