Cuando @theroundedman.bsky.social te decía en clase:

"Debéis tener copias de seguridad más allá de vuestra área de influencia"

Y tú pensando:

"Bueno Redondo, ¿qué puede pasar, que caiga un misil?"

AWS UAE suffers AZ outage after "objects strike data center" and cause fire, amid Iran attacks Availability Zone in ME-CENTRAL-1 brought offline in possible drone or missile attack

So, the outage comes because a missile impacted AWS infrastructure

Agree on the idea, but titles are still important because they (should) come with a salary raise 😉

Today, first time that really achieved managing 2 tabs of AI Agents at the same time 💪🏼

This is a good thing, right?... Right?

Choose wisely the way to deliver your MCP.

Nowadays, delivering MCP servers via Docker is my preferred choice because it offers a good balance between performance and version management.

The Future of Software Engineering with AI: Six Predictions Notes from The Pragmatic Summit and ‘The Future of Software Development’ workshop

Great newsletter issue @gergely.pragmaticengineer.com , worh for being a paid subscribed

Some (more than I thought!) software engineers are coming to me saying:

"Marcos, I’m scared about the AI, I think it will take over my job"

I say:

"No f*cking way"

But you don’t need to trust me, trust more expert people who are living in tech for much more than you and I.

But then you remember how long you don't use GitHub Copilot

When you run out of tokens in all models available in Antigravity

And what would be the purpose of that?

I've been in tech for a while and I don't remember this massive blast of news and evolution... Not even with cryptocurrency

I'm not able to follow the pace of so many things appearing every single day about AI...

Is it only me?
