Check out my new blog post, I have implemented a bare-bones GStreamer-like library in Python from scratch to show how some of the GStreamer abstractions work underneath. The idea it to help you create a mental model to work with the real framework. caricio.com/learn-by-exa...

One of the new skills required to get the most out of AI-assisted coding tools - Claude Code, Codex CLI, etc - is designing agentic loops: carefully selecting tools to run in a loop to achieve a specified goal. Do this well and you can solve many coding problems with brute force

Now we I look at some old projects, unmaintained, and I want to check it out. I look at bit in the code to understand it. Then I run Claude Code on it and say "make this compile and run, fix all compilation errors". It is magical.

I heard StackOverflow is “dying”. But something like StackOverflow will still need to exist in the future. Maybe not in its current form, but in my opinion, some hard factual solutions directory still have a place in a world of coding dominated by LLMs.

Making MacOS apps is not simple. Xcode is not a user-friendly platform.
eg. So many hidden menu items and heavily point and click.

- Has top accuracy (similar to Claude Code)
- Is completely open source, MIT licensed
- Is model agnostic, use an API or bring your own
- Is simple to install and run `pip install openhands-ai` and `openhands` (no Docker!)

I built a new LLM plugin that can turn a PDF into an image-per-page for feeding into vision models, and in testing it found that GPT-4.1 mini hallucinates WILDLY if you feed it a blank white rectangle followed by a blank black rectangle https://simonwillison.net/2025/May/18/llm-pdf-to-images/

I used to write notes on my phone for ideas I had on the go. Some parser for some specific format, or a script for something else. Lately, I write what I have in mind as a prompt to Claude Sonnet or Gemini 2.5 Pro. Review on my phone, then refine.

I just uploaded my slides for the talk I gave at Kamailio World 2025. I introduced RTP over #QUIC ( #ROQ ) and my new #imquic library, with a few observations on what future this may have, if any (especially considering most of the focus is on #MoQ instead)

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust.
In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

I was very skeptical of using LLMs for coding. Felt it was super distracting and wasting my time by driving me to wrong solutions.
