well, do it as soon as it opens up;

if you really believe it you found a free money glitch

jeanlucas··on Why are AI agents lying, cheating and coordinating?
The data to be open, in my case.

The "independent" METR that is composed by... Checks notes... Previously employees from the top labs.

jeanlucas··on Show HN: What if the speed of light was 5 km/h?
And any exponential growth is also a multiplication, it's not a big deal, just giving example on what they asked before.

Somehow people are interpreting this as some kind of math trick.

It's not a trick, our brains are not wire to deal with numbers growing quickly, but we do understand the math.

jeanlucas··on Show HN: What if the speed of light was 5 km/h?
Of course it is logical, we are not discussing the math.

But it isn't intuitive, you're not used to numbers that big or that grow that fast.

Few things go from a million to a billion, especially when related to time.

jeanlucas··on Show HN: What if the speed of light was 5 km/h?
One million seconds is 11 days, a billion seconds is 31 years.

You need to catchup with the last 15 years then. It's not new at all. But I agree it is getting worse, but it is getting worse every year for a while.
jeanlucas··on OpenLogi
Recent?

Oh dear.

If you really wanna worry about all of these things you better not use any open source from now on. Or even private software as well, because you can't even audit and know what "vibe code" touched.

jeanlucas··on OpenLogi
YES YES YES YES

That's perfect

jeanlucas··on What AI did to stackoverflow in a graph
Mostly: Discord, Github issues (as forum), X (twitter at the time), and Discourse! Discourse was growing steadily, even startups like OpenAI and neobanks like nubank (Brazil) had forums for their users because keeping your community active and close was something considered valuable (devrel since then has experienced a rapidly decline).
jeanlucas··on Show HN: I made email signatures less boring
We were this close to glory... This close!

But we got a generic 3D doll instead of forum-like signatures.

Just imagine something like this: https://i1168.photobucket.com/albums/r488/Vayne-D3/HybridSig...

Already 10x cooler, or maybe a long strip of startups / project you've done https://www.carlos-menezes.com/img/before-the-bio/smaller.pn...

The sale is relevant. The spike in activity right before the sale already shows the management hand and how they actively ran the org to optimize for this sale. The rebound right after is hard, and it was (right) before chatgpt

They accelerated the downfall with this and then chatgpt came over

jeanlucas··on What AI did to stackoverflow in a graph
I don't have the time to, but I'm surprised there aren't a lot of comments on the decline before chatGPT was released, but after SO was sold to Prosus [1][2]

Even the curious growth spike in activity happened just before the acquisition. I wish I had time to do this analysis a bit deeper, but you can look for SO activity up until when chatGPT was released, it is really noticeable.

Usually #1 actually works, most cases, and missing discord, several healthy communities on Discord nowadays
jeanlucas··on Codex starts encrypting sub-agent prompts
I was wondering why my local tool to inspect coding agent sessions stopped working in some cases.

This is a really interesting engineering decision, I wonder how many people will want an encrypted external piece of instructions running on their machine.

It's because you have not been paying attention (payin' attention)
jeanlucas··on Show HN: Veterinarian turned founder, AI lawn diagnosis
I am committed to some projects now, but I did a full analysis of projects to invest, used AI to validate ideas and so on.

My main goal was "solo founder projects as programmer" and one of them was software for veterinarians (second one was for golf tracks).

It is an interesting niche!

jeanlucas··on US Government directive to suspend access to Fable 5 and Mythos 5
And I got it as a Roman curse (or from Roman times). That is common with old sayings.
jeanlucas··on Larry Ellison: "Citizens will be on their best behavior because we’re recording"
Let me just add one interesting layer:

The current experiment in São Paulo, 8k+ cameras were added to the city with the same justification: security.

But, at least for smartphones robberies, the results are not obvious: on an average of 24 smartphones stolen every hour[1] in one neighborhood (Pinheiros is a big "tech" area).

I just want to point this out because this premise of more recording = more security = more behavior is not necessarily true.

jeanlucas··on Ask HN: What are you working on? (May 2026)
I am building several small tools for myself, no real intention of sharing them yet. Some have better solutions in the market:

* Advanced tab organizer, small chrome extension to organize my bad habit of 200+ tabs, can group them into windows, search, close duplicates, search just on a specific window. Pretty fun.

* A clipboard manager, just wanted to build something in Swift for fun

* A todo app for mac, local-only

jeanlucas··on Wacli – WhatsApp CLI
I personally don't use whatsapp because I like it, but because all my contacts in my country are over there. It is officially more used than SMS here. It is not optional in my case :/
