A bit of very large technical debt has just reached its balloon payment.

An absolutely 100% mission-critical, it's-where-the-money-comes-in Django backend is still on Python 2.7, and that's become unacceptable. It falls to me to convert it to running on Python 3.14 (along with the various package upgrades required).

Decorators are great!

After a long, long time trying to wrap my head around decorators, I am using them more and more. I'm not suggesting I fully grasp metaprogramming in principle, but I'm really digging on decorators, and I'm finding them especially useful with UI callbacks.

New Python module: thermocouples, voltage-temperature conversion and Seebeck data

Hey everyone,

I recently released a Python module called thermocouples, designed to make working with thermocouple data straightforward in Python.

  • Get the Seebeck coefficient (µV/K) at any temperature
  • Calculate dSeebeck/dT (nV/K²) for advanced analysis …

Building a Python version of Spring Batch — need opinions on Easier-Batch architecture

Hey everyone,

I developed this small project on GitHub called Easier-Batch.
It tries to bring the same philosophy as Spring Batch into Python — using the familiar Reader → Processor → Writer model, job metadata tables, retries, skip logic, and checkpointing.

I’m currently designing something similar myself — a …

I made a number-guessing game… but it lies to you.

What My Project Does

This project is a simple Python number-guessing game with an unusual twist: the program occasionally provides incorrect hints. Using weighted randomness, the game decides whether to tell the truth or intentionally mislead the player. The player has a fixed number of attempts to guess the secret …
