The question isn’t if there will be an AI bubble burst, but when - and how big.

Every wave of significant new tech - no matter how “good” - has followed the same pattern, in part because of inflated expectations and a long lag before adoption delivers real impact (see Solow Paradox).

Muchas de las cosas consideradas como “obsesión” o “frikismo” por la gente que se considera normal, es en realidad motivación intrínseca pura. Ese tipo de motivación, bien dirigida, mueve montañas.

Documenting API Governance How do you document the processes behind API governance?

Since API governance is a service, I thought of using an appropriate documentation method, instead of "reinventing the wheel."

Everything Wrong with MCP Explaining the Model Context Protocol and everything that might go wrong.

Me ha gustado este artículo sobre aspectos que se tienen que mejorar si o si en los MCP. Algunos de estos aspectos suponen oportunidades de negocio bastante interesantes.

With release 1.11b we completely removed the web panel feature. You can find a statement on that in the release notes here zen-browser.app/release-note...

Also, we've added this nice button in the Glance menu!

This is ALL hexagonal architecture is about.
The same that was proposed a decade before.
No hexagon, no architecture.

I've often listened to someone blaming old, useless UML but at the same time enhancing how you should use hexagonal architecture.
Please don't follow stuff with horse blinders!

Last month AI crawlers generated 90% of my site's traffic, forcing me to pay penalties

Problem solved after moving nameservers to Cloudflare+turning on AI crawler blocking.

Site monthly outbound data back to ~40GB per month, down from 800GB (!!) No impact on human visitors

The most useful code isn’t the code that solves every future problem.

It’s the code that’s easy to change.

You don’t need perfect foresight.
You need feedback from real users—and a codebase that can adapt.

Good systems evolve. Give them room to move.

With the potential that generative AI has, allowing it to be used for this… hopefully, in a few years, we’ll look back on it the same way we do on the time when smoking was allowed on buses. Like a completely nonsense.

This is extremely sad and a huge disaster for the entire Japanese cultural industry. And the fact that it started specifically with Studio Ghibli makes it even harder.

Too many people accept opinion as fact, or deem anyone capable of stringing together a complete sentence to be intelligent, which is why LLMs seem like a suitable replacement for the people around them.

Building software should be sustainable. Quality and feeling good at the end of the day matter more than constant pressure and accumulating technical debt.
