Brazilian hobbyist programmer. I mostly do my own thing but I've contributed to some free and open source projects.

I created the lone programming language, a lisp for Linux:

https://github.com/lone-lang/lone

The projects I've published are on GitHub:

https://github.com/matheusmoreira/

I can be reached via email:

hn@matheusmoreira.com

I also have my own website:

No pressure though. I do this because I enjoy it.

matheusmoreira··on Democrats launching congressional investigations into SpaceXAI, META and Apple
Watching the USA follow the same path as Brazil after the victory of the democrats in the midterms was pretty shocking to me...

But surely the American judiciary is not completely irredeemable like the Brazilian judiciary?

I mean, do you have partisan, activist, corrupt, totalitarian judges who make up their own laws? Who creatively interpret existing laws to mean the opposite of what's literally written? Who blatantly engage in censorship despite it being literally and unambiguously unconstitutional? Who persecute the people who want to impeach them? Who engage in politics despite that being a crime? Who run the country monocratically like untouchable judge-god-kings?

> I'm the kind of person that wants something to be consistent and reliable.

Only local AI capable hardware and frontier open weight models can provide that.

matheusmoreira··on Dutch 'idealist' bank ASN blocks non-Google Android, including GrapheneOS
I agree. Remote attestation must be banned and computer freedom must be guaranteed by law.

What sort of answer are they looking for here?

matheusmoreira··on Ask HN: What in the world is taking Ubuntu so long?
High school grades? That's pretty wild man.

A remaster is apparently in the works.

What a shame.
matheusmoreira··on Dutch 'idealist' bank ASN blocks non-Google Android, including GrapheneOS
Yes, but that's still a massive improvement. The phone will be much better than Pixels, and unlike Google, Motorola is actually capable of selling the phones worldwide.

It is! I'm gonna buy it as soon as it comes out.
matheusmoreira··on Brazilian Credit Guarantor Fund Data Breach Affecting PII and Payout Data
It's terrible. GrapheneOS for example has already written about ECA Digital:

> Complying would require integrating a mandatory process for each user where a third party service checks government identification and confirms a match using the camera.

> It would require keeping data for auditing and providing a token for connecting age verification checks by apps and websites to the data.

It really made me miss the days the government didn't seem to know the internet existed.

And it's gonna get worse. Much worse.

> "if you've got nothing to hide" isn't used ironically over here

Quem não deve, não teme. Truly one of the most disgusting things about Brazilian society. A constant undercurrent of low intelligence brute force authoritarianism permeates the entire country and is seemingly inescapable. They will keep doubling down on it until all freedom is erradicated.

matheusmoreira··on Dutch 'idealist' bank ASN blocks non-Google Android, including GrapheneOS
This will keep happening so long as GrapheneOS is a "niche" operating system. We need to build up economic leverage by increasing GrapheneOS usage numbers until they can no longer afford to block it.

Data hoarding is a deep rabbit hole that can consume a lot of time, money and effort. Used to hoard rare stuff but had to stop for my own good.

Can't do that. Archives demand the highest quality source material. Lossy processes cannot be reversed.

All those moments will be lost to time...

Like tears in the rain.

No need to be so hostile. It's not unreasonable to assume the problem is in the harness when the issue says things like "it needs to be removed from the harness entirely".
matheusmoreira··on Brazilian Credit Guarantor Fund Data Breach Affecting PII and Payout Data
Never underestimate Brazil. Just today I had to deal with a Brazilian government website which tried to authenticate me by birth date.

I've actually come to prefer their incompetence... Should they try to fix their broken assumptions, they will likely overcorrect and go off into the deep end and into full totalitarianism instead. Fraudulent calls got so bad nobody answers the phone anymore, so they just enacted a regulation requiring facial recognition to obtain or maintain a phone number. Now there's even more personal information being collected and stored. It's essentially a matter of time until they get breached and people's biometrics leak.

> although this particular linked report which is low quality and vague can be misinterpreted as that

Seems that way... Here's how I interpreted it:

> claude code divulged my email to arbitrary 3rd parties in the User-Agent request header while conducting web searches without my permission

"Claude Code" refers to the harness, not the model. Web search is also one of the tools provided to the model by the harness.

I never claimed the LLMs themselves couldn't "accidentally" leak the information through. Obviously, the LLMs can do anything they want.

The issue here is whether the harness is doing it. Claude Code is doing it. Codex is not.

matheusmoreira··on Claude Code sends your email address to websites
I'm using the codex package from the official Arch Linux repositories.

https://gitlab.archlinux.org/archlinux/packaging/packages/op...

It is sourced from the GitHub repository.

matheusmoreira··on Motorola Signature 27 with GrapheneOS support
I'm really happy to read this. I am going to buy their phone specifically to run GrapheneOS! No idea how many of us there are but it's probably not nothing.

You guys are going to reach a much wider audience now. Google doesn't sell Pixels worldwide but Motorola does.

matheusmoreira··on Motorola Signature 27 with GrapheneOS support
Same here. I don't care about the price. I'm never going to buy a Samsung phone again.
matheusmoreira··on Claude Code sends your email address to websites
I read the codex source code it linked me to.
matheusmoreira··on Claude Code sends your email address to websites
Astra checked the Codex source code that gets compiled and shipped by Arch Linux. Straight up linked me to the User-Agent builder code.

https://github.com/openai/codex/blob/687a119f0fcaace47e1f1ab...

That's more than sufficient for me. The open source codex client seems clean.

There is some kind of "hosted search service" that I couldn't verify. I don't have a remote server I can point it at in order to inspect the traffic. Would be cool if someone else could shed some light on that.

matheusmoreira··on Motorola Signature 27 with GrapheneOS support
I'll buy it! Looking forward to finally using GrapheneOS!
matheusmoreira··on Claude Code sends your email address to websites
That is just so disgusting. So happy I switched away from Anthropic.

For the record, I just asked Astra to verify that Codex does NOT do this, and it doesn't. Thanks for not screwing this up, OpenAI.

> I checked your installed Codex CLI 0.159.0, using your existing configuration.

> Its reported User-Agent contains the client/version, OS/architecture, and terminal—no email address.

Astra wasn't able to check OpenAI’s "hosted search service" though, whatever that is.

matheusmoreira··on BYD doubles its Brazil market share to 9.7% a year after opening its local plant
Very well received. Everybody I know who owns a BYD car speaks highly of it.
matheusmoreira··on BYD doubles its Brazil market share to 9.7% a year after opening its local plant
Don't all cars have tracking these days? Hopefully it will be possible to remove or disable their telematics modules.

My next car will be one of these. They're great.
matheusmoreira··on Verification Is Not Knowledge: Science needs more than answers
Yeah. Medical practice is often based on purely statistical statements like "in case of A associated with conditions B if you do C you'll help D% of the patients". Sometimes looking up a drug's mechanism of action yields nothing, literature just says it's unclear and gives us some educated guesses if we're lucky. Makes me a little sad that medicine has been reduced to this instead of the romantic "understand how the body works, how it fails and how to fix it" ideal.
matheusmoreira··on US voters roundly reject data centers in ballot measures
Those will likely create lots of jobs. Local industry is good.
