5 things we can learn from OpenAI's use of tools
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.

Netflix acquires Warner Bros
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.
Atomic Habits
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.
