Show HN: Montmark – A lightweight, fast pure-Python Markdown parser

desgeeko — Fri, 12 Jun 2026 21:22:02 +0000

Hi HN!

This is a pet project that is still a little bit rough around the edges, but I would love to hear some feedback.

I write this code by hand, out of love for Markdown and for the joy of solving every CommonMark test case like a puzzle.

Cheers

Show HN: MicroECS – entity component system library in Python/NumPy

meehai — Fri, 12 Jun 2026 06:21:24 +0000

Hi, in the last ~month I've learned a lot about ECS [1,2].

I'm currently developing a robotics simulator from scratch (python+raylib) and, due to lack of game dev experience I went "full OOP" on it. A SceneObject with a lot of inherited interfaces (e.g. Collidable, Movable etc.). These are inherited and fixed at run time.

The main loop inevitably became:

  for scene_object in sim.scene_objects:
    scene_object.update(...)
  for scene_object in sim.scene_objects:
    scene_object.draw(...)

Well, it turns out that this can become a bottleneck if you have many scene objects because computers love contiguous memory for caching, physics/math vectorization and so on.

Having recently learned more about ECS[1,2], I started doing a bunch of experiments in a sandbox with turning the update() function into ECS. The idea is that the data is stored in columnar numpy arrays (components) + a lot of data structure optimizations for querying scene objects and fast access e.g.

  qr = scene.query(HasMotion, HasPosition) # query result acting like a np array of (N, ...) shape
  qr.position += ... # operate like numpy / vectorized

In any case, the standalone library only needs python and numpy. Raylib is only for rendering, but the raw data structures don't need it.

I'd love some feedback on it, e.g. what is it missing or what are gotchas I'll find out later on during the simulator development.

As an anecdote: I used Claude as an 'engineering manager', I wrote the code myself, it did the code review, tasks management and tests (super useful for corner cases).

Show HN: Llmbuffer – Python library for cache-optimized LLM conversation history

scottmp10 — Wed, 10 Jun 2026 22:26:11 +0000

I was not getting good cache utilization when including dynamic context in agent threads. After a lot of experimentation, I found a good pattern that minimizes how often long lived conversation history gets modified while still supporting dynamic context. It has flexible hooks for doing things like truncating or summarizing tool outputs when transitioning messages to the long term history. And I'm seeing >>90% of tokens hitting the cache for my agents despite including a lot of dynamic user context.

There are a wide range of agent prompting strategies so I'd love to hear where this library works well and where there are patterns that don't fit well into the current API!
