   I built a hardware processor that runs Python▲983

   Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…

   Pypipe – A Python command-line tool for pipeline processing▲213

   pypipe is a command-line tool for writing data pipelines in Python. When working with data processing in the terminal, I often find myself wanting to pass the output of commands to Python for further processing. In such cases, one can either write one-liners or create regular Python scripts and connect them through pipes. However, using pypipe makes this process more convenient and efficient.

   deptry 0.14.0 – detect unused Python dependencies up to 10 times faster▲142

   deptry 0.14.0 was just released, bringing significant speed improvements: It is now up to 10 times faster than the previous release! For those unfamiliar with deptry; deptry is a command line tool to check for issues with dependencies in a Python project, such as unused or missing dependencies. GitHub: https://github.com/fpgmaas/deptry For some benchmarks of the new release, see the release notes: https://github.com/fpgmaas/deptry/releases/tag/0.14.0 The performance improvement was achieved by leveraging Rust to parse the AST and extract…

    Pipelex – Declarative language for repeatable AI workflows▲122

    We’re Robin, Louis, and Thomas. Pipelex is a DSL and a Python runtime for repeatable AI workflows. Think Dockerfile/SQL for multi-step LLM pipelines: you declare steps and interfaces; any model/provider can fill them. Why this instead of yet another workflow builder? - Declarative, not glue code: you state what to do; the runtime figures out how. - Agent-first: each step carries natural-language context (purpose, inputs/outputs with meaning) so LLMs can follow, audit, and optimize. Our MCP server enables agents to run pipelines but also to build new pipelines on demand. - Open…

    Pipask – safer pip without compromising convenience▲52

    Pipask is a drop-in replacement for pip that addresses a serious security flaw: standard pip executes arbitrary code from source distributions during dependency resolution, without warning or consent. Pipask retrieves metadata through PyPI's JSON API first, then checks repository popularity, download counts, package age, and known vulnerabilities before allowing installation. It presents you with a pretty report and asks for you consent with installation, giving you control over what code runs on your system. More details in the intro blog post:…

    Strict interfaces and dep management for Python, written in Rust▲68

    Tach is a pip package that lets you define module boundaries, automatically detect all cross-module dependencies, and then validate and enforce those dependencies. It also supports strict interfaces for modules by overloading `__all__`. The core static analysis is done in Rust, so all Tach commands run quickly. The goal of Tach is to help eng teams maintain velocity while scaling quickly, something we've seen break down a number of times. Give it a try!
