Building on Bluesky's AT Protocol with Ruby Overview of the architecture of the AT Protocol network, some examples of the projects I've built on it with Ruby, and a showcase of some other people's…

Interestingly, the more companies I get to know in San Francisco, the more I can see the difference in mindset between US and EU.

In SF, it’s all about constantly evolving and trying new things. While in EU, there’s a constant fear of change, therefore a lot less innovation.

For those managing AI plugins, SKILLS, and/or Agents for AI coding:

How do you manage the ownership for each to avoid a mess in your repository?

Ese comportamiento de algunos C-Level es como una especie de "virus" que se expande... Creo que se llama algo así como "quiero dinero de inversores y por eso digo que la IA potencia mi empresa lo que lo está escrito"

Glad you like it! It's a great event in Spain!

If you want to get started with Genkit, this is the perfect place to begin!

What happened!? 😱👀

What if I tell you, and I just had a call with a friend who told me:

Marcos, using Claude Code I’ve made a change in 2 hours, which I would have measured as 1 week if I did it by myself… and Claude Code dashboard tells that I used $20 🤯

Don't know who thought that sharing an URL with parameters, for such an important and commonly used web page such as the Next Train Departures, was a good idea.

What will happen when that value changes? (Because it will)

Why not use just a subdomain or a fixed path?

Six months ago we were writing dev guidelines, so devs could understand what to do.

Today we ask for SKILLS

He preparado esta presentación sobre riesgos de ciberseguridad de la IA generativa para un congreso y la he puesto gratis aquí para quien le pueda interesar :):

Do you use different agents, with different roles, to work together at the time to solve a problem?

What agents do you have, which roles do they have, and what are the SKILLS attached to each?

Soon, I will publish an idea for reviewing pull requests in AI Native age ☺️😉

From Technical Debt to Cognitive and Intent Debt: Rethinking Software Health in the Age of AI Generative AI is accelerating software development, but may quietly shift where the most significant risks lie. As AI generates code faster than teams can understand it, two under appreciated forms of...

For those who actually manage people, agreed 💯💯

For those engineering managers who do not manage people, I think the AI could make their work.

Pero el pelotazo vendrá cuando esto se democratice de tal forma que esas herramientas no sean sólo para desarrolladores sino para para el público en general.

Y ahí entran las SKILLS como la que has puesto.

Trabajadores de educación, administración, servicios, turismo, ...

Esto es un nicho muy importante en mi opinión.

La mayoría de la gente no usa herramientas como Claude Code, Cursor, etc, porque están orientados la desarrollo de software.

True! Every tab was a bet! But the dopamine started to flow in every single tab, tab, tab, and so you ended with something you don't know if "that works" or not 😅

Do you remember when you were coding with AI by doing tab, tab, tab?

So, does this mean that we no longer need Engineering Managers? 😱☺️

Siento parecer el pesetero, pero: Y con sueldos competitivos

Acabo de ver esta oferta de trabajo.

I have no problem confessing that, once I understood this, I started to perform better as a Tech Lead

Es cierto, yo lo veo también.

Mi teoría es que se hacen ese "buffer" para usar ese tiempo para poder enfocarse en otras cosas.
