Articles, Tutorials and Talks
Learn how OpenAI evolved Habitat from a Python library into a globally distributed storage platform serving 1 billion ChatGPT users and 22M requests per second.
Eddie Atkinson makes the case that many teams move from Pandas to distributed systems too early, when single-machine tools like Polars and DuckDB can handle much larger analytical workloads with significantly better performance and memory efficiency in his benchmarks. He highlights lazy execution, multithreading, streaming, spill-to-disk, and Arrow interoperability as reasons these tools can cover many “medium data” workloads without the complexity of distributed systems.
Philipp Schmid demonstrates how improving LLM capabilities allow developers to replace complex Python agent orchestration with simple instructions and skill files (AGENTS.md and SKILL.md) running inside hosted sandboxes. By building the same GitHub pull request review agent three times, he shows why developers should simplify agent architectures, rely on general-purpose tools, and focus on instructions and evaluations instead of maintaining unnecessary orchestration code.
The article explores 4×4 Sudoku, showing that there are 288 valid solutions, which reduce to just 12 structurally distinct grids when digit permutations are ignored. Using Python brute force and a clever bitmask technique for checking minimal subsets, the author identifies 85,632 minimal puzzles (3,568 up to digit permutations), each with a unique solution that becomes non-unique if any given digit is removed.
Python 3.15 is almost here! This video breaks down 10 of the most interesting new features and changes coming to Python 3.15, using real Python code and visual explanations.
The article explains when to use re.prefixmatch(), re.search(), and re.fullmatch(), what soft deprecation means for existing code, and how to flag re.match() usage with Ruff.
The author details building an MLIR backend for Python's Finch sparse tensor compiler, covering type conversion, buffer management, SSA values, control-flow lowering, and SciPy sparse interoperability. Benchmarks show MLIR outperforming Numba on most tested kernels and beating SciPy on more complex sparse operations, while highlighting current limitations and plans for GPU support.
Adam Johnson explains how to implement the standard /.well-known/change-password URL redirect in Django using RedirectView, helping password managers direct users to their password change pages. He also covers testing the endpoint, checking for server misconfigurations that could interfere with password managers, and setting the correct autocomplete attributes on password fields.
Ben Tasker shares his experience customizing the Badgeware Badger—a Raspberry Pi RP2350-powered e-ink name badge running MicroPython. He details troubleshooting image formatting, color-depth, and font sizing issues to display his custom avatar, a Fediverse social handle, and logo on the device.
The video demonstrates building a polling application with FastHTML, covering form creation, POST request handling, and storing polls in a database. It also shows how to define database models using Python data classes, create a voting page, and process submitted votes.
NumPy in the browser now uses OpenBLAS through Emscripten-forge, accelerating matrix multiplication by up to 30.92× for float32 and 14.90× for float64 in the authors’ 1024×1024 benchmarks. The article details the WebAssembly and Fortran toolchain work behind the improvement, plus upcoming SIMD optimizations that push performance further, reaching up to 64.89× with optional Relaxed SIMD in the same benchmark
Distributed systems synchronise themselves without being told to: every client that retries on a fixed interval, restarts after a deploy, or reconnects after a network blip ends up firing at the same moment as every other client. The resulting spike is a self-inflicted denial of service that no single component is responsible for. Adding randomness to any repeating interval breaks the alignment, and it is usually one line of code against a failure mode that otherwise requires capacity you never needed.

New Releases
JupyterHub 6.0 introduces stricter named-server rules, more granular API permissions, improved spawn-failure reporting, and internal HTTP communication via aiohttp. The release also raises the minimum Python version to 3.10, replaces StatsD metrics with Prometheus, and includes a database schema upgrade that requires a backup before updating.
