I f*cking love data.

I was asked in an interview about talks or public presentations I've given. Thought it might be useful to publish them here. Most of them are in Spanish, but here goes anyway: 1. Modern Data Stack @thedatapub An attempt to demistify the word "modern" by going through the cycles…

When I was 18 I was walking with a friend and we saw some dudes at the park practicing walking over a rope, like circus stuff. My friend said “you know, I could do that if I wanted to.” It was weird, but then he followed with “I can do anything I want to, I can learn anything I…

Note that Manus were the first to make editable generated slides. Slides which btw are only possible via GOOG nano banana. So, where’s Microsoft in all this?

Manus is entering the next chapter: we’re joining forces with Meta to take general agents to the next level. Full story on our blog: manus.im/blog/manus-joi…

Claude Code’s creator saying this. So, it’s not some non-technical or junior level talent one can be dismissive of. Incredible stuff.

Correct. In the last thirty days, 100% of my contributions to Claude Code were written by Claude Code



Organizations now have access to a magical API that given the right context can generate this level of high quality code. Question is, what will be their reaction?

My strategy in 2026 is to pick one agent (opencode, cc, amp, codex) and one model provider (Anthropic, OAI). Commit long enough to learn the quirks, and focus on improving my context skills. I don’t see any other way to consistently extract good code from the shoggoths.


I’m uncertain about the proper level of bureaucracy in an organization. Some of it is necessary, you gotta make the work legible, but requiring authorizations for pip installs like some orgs do is going too far.


You’ve gotta hand it to Anthropic, they nailed model naming. Fast -> Haiku Standard thinking -> Sonnet Deep reasoning -> Opus Compare that to whatever OAI is doing.

“The vast majority of AI tokens in the future will be used on things we don't even do today as workers: they will be used on the software projects that wouldn't have been started, the contracts that wouldn't have been reviewed, the medical research that wouldn't have been…


there is $100m stuck in claude your job is to figure out how to get it


I have a pipeline of 6 scripts that clean some data. They have inline deps and are easily ran via uv without any venv. Question is, do I create a CLI out of them or some skills? Or do I create a CLI that then I turn into a skill? Or, nothing lol, just keep them as is.


This post will be remembered for the years to come

We're opening limited access to a research preview of a new agentic coding tool we're building: Claude Code. You'll get Claude-powered code assistance, file operations, and task execution directly from your terminal. Here’s what it can do:

This is the way for Econ

Can AI "learn" economic states, addressing the Lucas Critique? With @alexolegimas we simulated data from an NK model, fit a transformer, and tested out of sample fit It generalizes surprisingly well. We hope this stimulates discussion and future agendas arpitrage.substack.com/p/can-a-transf…

uv scripts will turn into the default way to give agents skills


you see it’s called an agent cause it has agency Gary

It was known, so the official announcement is good

🆕 Codex now officially supports skills Skills are reusable bundles of instructions, scripts, and resources that help Codex complete specific tasks. You can call a skill directly with $.skill-name, or let Codex choose the right one based on your prompt.
