A black and white figure's thought-hive
A new leak tells us about how to properly code agents
On December 12th 2025, a tweet demonstrated that ChatGPT would deliver files from its home directory when asked.
Beyond security concerns, what does this reveal about OpenAI’s use of tools and agents for GPT 5.2 Thinking?
A new era of multimedia might be around the corner, and we're watching it happen
Aside from the jokes of the future one-single-corporation that runs every piece of media, I think we’ve all been surprised that Netflix has acquired Warner Bros., and while I have a lot of opinions on what that might mean for the multimedia world, there’s one aspect that has been brought up, not confirmed, that has been making the rounds on social networks.
A review on James Clear's book
I recently finished reading Atomic Habits, from James Clear, a long time recommendation I have been putting off. It definitely was a good recommendation, but maybe the expectation was a bit high for this one.
I ported Micrograd to Rust
You might remember that I was doing small applications in Rust to try out the language, learn about it and eventually become a pro at it. That’s… in progress. But in the meantime, I’ll tell you about which things I’m finishing up and I’m learning.

In the last few weeks, I set up my own media server to replace a particular service I did not want to pay anymore. It felt like a huge chore with lots of options but it’s not so difficult once you get into it.
Here’s my journey and hopefully it’s useful to you too.
Based on a true story
I got so mad about this that I had to write a blog post. Consider this an edu-rant.
Who needs to write anyway
I learned Rust and I decided to make something to automate blog post creation with GPT-4o. I’ll tell you a bit how that worked out.
Keep your notes in sync
For a few years now I’ve been using Obsidian as my second brain. The magic of Obsidian is that it’s only a bunch of markdown files and a clever editor on top of it. This means that any file-syncing solution should be good enough. But the truth is a little bit more complicated than that.
Natural language is hard!
This whole shebang about AI and AI-enhanced products has led me to one of the products that have become part of my daily usage: Perplexity.AI. It’s a search engine where you ask questions and it gets your answers from the internet.
Let me take you back a couple of decades before we go back to it.
