Way of life, quotes and second brain. While I organize the books and articles I've already read, Claude recommends other sites, posts and books. And I ended up…

When people ask me whether they need to know mathematics, physics or calculus to be good programmers, I always say not necessarily, but that you do need that…

Sapir-Whorf, slicing reality and professions. The reference of Villeneuve's film, Arrival, is very strong for me. Ted Chiang's short story gave me several…

Boris Cherny, creator of Claude Code and an active voice on AI social media, posted a reflection on the professions of the future and archetypes these past…

Yesterday at the IA Conference Brasil event, I had the chance not only to give a talk, where I basically presented my human out of the loop article, but also…

I reread I, Robot and the last story reads like a manual for our feed: the Machine that knows what you will disobey, the casino algorithm running the stories, and a p(doom) with no armed robots. It just has to choose for us.

I went back to writing. After this whole new harness mechanism of Claude Code, which has been excellent since December 2025, I got excited about picking the…

I keep browsing my notes, especially the ones I used to create talks. Notice that some themes keep coming back. One is something I use a lot: you are not paid…

OpenAI's Astra, the fold-and-cut theorem I implemented 20 years ago for my master's, and what is left for beginners when the machine does in 65 minutes what took a year.

Dash-Shaped Professionals. I harp so much on the T-shaped professional (I already talked about it in this note, in Portuguese) that sometimes I am even afraid…

AGI is a subject I don't much like talking about. I even agree with Sam Altman, who says it is not a super useful term and at the same time a concept that is…

Terence Tao is one of the greatest living mathematicians and he gave an interview to Big Think, where he makes analogies that I found very pertinent and also…

Bill Gates's essay on the turbulent AI era, productive struggle in education, human relationships and Leo XIV's encyclical Magnifica Humanitas.

We keep having to reflect on the impacts of artificial intelligence on software engineering practices, now that it writes code well. At one talk or another,…

In the US it has become common for people in therapy to have intense relationships with robots and bots. The big outlets are paying attention:…

I moved and set up wi-fi, Home Assistant and smart lights with Claude Code as my copilot. Along the way: reverse engineering of protocols, forks, pull requests and the graveyard of little systems that AI is multiplying.

The Pope's encyclical is sharper than I imagined. It goes after the points I really like in the broad discussion about AI. In the paragraphs about school,…

The T-shaped professional is not new, but has never been so necessary. From Werner Vogels at AWS to Bill Gates, by way of Martin Fowler.

The problem is not widening the information funnel. It is storing, annotating and triaging what you have already decided to see and hear.

I wanted to keep my impression short. We have been watching this AI tooling grow and we are amazed. And then we try to apply the latest version of something…

The social acceleration of time goes from the corporate world to the personal one. Metrics, OKRs, heart rates and the self-programming of those who write software.

Social media and vibe coding share the same accelerated dopamine mechanism. The difference between yearning and craving, and why we need intention.

From XHTML to Markdown, from LaTeX to Anthropic's Skills: how simple formats beat complex ones, and why text is at the center of the future of computing.

When I used to teach basic Java, in the first class I liked to spend a bit of time explaining why Java exists. I would tell the whole story of James Gosling…

How I built a custom PKM with vibecoding, Telegram, Whisper and LLMs so I'd stop losing ideas

How AI agents mix code creation and execution to research genealogy, and why the human remains essential in the loop.

Vibe coders are announcing the death of SaaS, but what we are creating are souped-up HelloWorlds: disposable software, with a very specific context.

LLMs and agents can reverse the dynamics of walled gardens. Content discovery doesn't need to depend on feeds controlled by closed platforms.

How OpenClaw made me feel I am really talking to the computer, and motivated me to bring this blog back to life.

This is one of the topics that comes up often among Silicon Valley thinkers. And the loneliness epidemic is also a focus of the WHO.
