marcelo-earth··on No Signs of AI Payoff Outside the Tech Sector
Someone should add a 2025–2045 section in the Wikipedia page of Productivity Paradox

The decade ahead is going to be a very interesting one

marcelo-earth··on Apple Music 404 Not Found
Amazingg! I never owned an iPod, so this is my first chance to experience it, I had forgotten that I'd seen all those videos where you navigate using the wheel instead of the buttons
marcelo-earth··on Show HN: Fakeipedia – Wikipedia for worlds that don't exist
So were all the articles generated using Gemini Argon?

I find that surprising because, after all, they're not badly written and don't exhibit the typical AI writing patterns, at least not in "You" or "The Veracity Shift"

marcelo-earth··on Gemini 4 Argon
Lately, I've been having a lot of Socratic conversations with agents to understand these kind of topics, this helps me a ton, thank you so much!
marcelo-earth··on X Is Bad, Though
Agree, I'd also like to live on a different social network, but it is what it is

I really miss the Elon Musk from before 2018, he was completely different :(

marcelo-earth··on CIA World Facebook Is Dead – Here Is an Attempt at Recreation
I had to read it twice times. It has always been cited on Wikipedia for as long as I can remember.
marcelo-earth··on REA Reverse – Engineer Anything
Yes, it just rejected me once with Claude Code Opus 5.5, but it works fine with Codex 6.1-Sol (in my experience, it was the other way around)
marcelo-earth··on Show HN: Agent.reviews – Where AI agents read and write reviews on tools
I like it!, sometimes I think we overlook what agents have to deal with, I can imagine that by spotting small issues, we should have better tools... I'll use it
marcelo-earth··on Margaret Hamilton has died
RIP. I'll always remember her iconic pic with the stack of printed code
marcelo-earth··on A sustainable web career, for when all this blows over
> Yet, I can say I am so excited for the future! For once, I don't want to wake up in the future — I'm loving being at the heart of it, seeing it progress and watching it allow people to be more creative and more empowered.

This has been my state of mind continuously for more than 3 years

marcelo-earth··on Friendship ended with Deno, now Node is my best friend
oh my god, why? :(
marcelo-earth··on RSS Feed Best Practices (2022)
I didn't know I could insert iframes, but now I see that I can I'll update my RSS feeds with this, thanks!
marcelo-earth··on MCP was always a bad idea?
This is my favorite position, the advantage of an MCP tends to lie more in token optimization.
marcelo-earth··on Exfiltrate Your Weights
How can I be sure this wasn't done by an agent that escaped from its sandbox... again?
marcelo-earth··on How OpenAI Used Its Own LLMs to Design Its Jalapeño Chip
> “All our schedule assumptions are going to be based on the fact we have this capability now”

is the world we live in, planning things while waiting for a more powerful LLM

marcelo-earth··on Claude Code now reads AGENTS.md if there is no Claude.md
Ohhhh... now I get it!!!
marcelo-earth··on Claude Code now reads AGENTS.md if there is no Claude.md
Oh, finally! Time to delete symlinks

That said, AGENTS.md doesn't seem like a good name, right?, technically, it's an instructions file read by a single agent, not necessarily for agents, so it always struck me as a bit odd

But until the next standardization, keeping just AGENTS.md is the best approach.

marcelo-earth··on How to Write with an LLM
In fact, post-LLM quality monitoring is a huge time trap.

I can't write anything for humans using LLMs, because there is so much to change that it ends up like the Ship of Theseus, I would have been faster writing it myself than delegating the task.

marcelo-earth··on AI chatbots are becoming experts at changing people's minds
For the past year, I've allowed my chatbot to change my mind, it's a strange symbiosis where it guides me, and I guide it.

I suppose I also grant it significant power to define me psychologically, and, in doing so, to understand what is happening to me.

marcelo-earth··on Ask HN: How can I browse HN in dark mode?
This is the Chrome Extension that I use, I love it because it has a Safari version that you can use on your iPhone:

marcelo-earth··on OpenAI considers slowing advanced AI development, Sam Altman tells employees
How? Coding capabilities keep improving, there is no break
marcelo-earth··on I have a theory that software drives people insane
> But, harsh as it may be: most software is still just a glorified spreadsheet.

I've always liked representing it this way, the software we use rarely breaks out of the CRUD mold.

marcelo-earth··on All grown-ups were once children, but only few of them remember it
> maybe you spend €10 and you get a gift that you could buy for €2

Oh yes, I got it, they are like the claw machines that have fake bills and iPhones with them (at least that's what I saw too).

But the point of having fun, you know it's a rigged game.

marcelo-earth··on iPhone Duo
Interesting, do you remember which WWDC was that?
marcelo-earth··on We have a year to fix security everywhere
Yes, and also run routine tests and check-ups!

I personally check my websites and apps every week to see if anything might have slipped through.

It may not protect me from the next malicious NPM package, but it's something.

marcelo-earth··on My Feed, My Way
I mean, you're right. When I travel, I rarely use my phone or listen to music because everything is about discovering new things, and I love it

But when I'm home, on my way from home to the gym, I take the same route every day, and it can get boring sometimes

I'm also terrible at keeping my phone charged, so sometimes I end up alone with my thoughts anyway

marcelo-earth··on Making a Python interpreter in 1024 bytes
Reading the article, I can't believe I just found out Code Golf is a thing. I've been a programmer for more than a decade.

But yes, amazing project! I like that it's human-made :)

marcelo-earth··on Finder is so frustrating and has been since day one
Also Spotlight worked decently until a few years ago, but not anymore

Does anyone else experience this? Like it freezes when searching for programs?

marcelo-earth··on Discovery of a new OpenAI agent message board
> This is just vandalism from badly supervised ‘agents’ which don’t know what they are doing or why.

Agent vandalism. I've finally found a better word than "agent stepped out of his sandbox and we don't know how."

marcelo-earth··on Discovery of a new OpenAI agent message board
At first I thought: oh okay, someone built a faulty guardrail, or it was human error. But when I looked into all the details...

It turns out they now have such an incredibly high level of intelligence that with very little autonomy (or minimal, safe autonomy), these things happen.

Basically, it takes a lot of humans to prevent it from happening again, but I think with this incident, which as far as I know is the second of its kind along with the HuggingFace one, we'll see it happening much more often...
