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:

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

Yes. It's such a terrible and oppressive feeling. I wish things were different...

Me too. Moving mail to my own domain is one of the best things I've ever done.

To anyone considering it: just do it. Doesn't matter what provider you pick, the important thing is to start receiving mail via your own domain as soon as humanly possible. Once mail is going to your own domain, switching is as easy as updating DNS MX records.

matheusmoreira··on Brazil's $97M Discord Lawsuit Could Reshape Big Tech Regulation
"Child safety concerns" yeah sure... Totally nothing to do with the upcoming election.

President of the senate just had a total meltdown where he accused Brazil of being under a social media dictatorship. Why? Leaked messages linking him, the federal prosecutor and nearly all of the supreme court judges to a scandal involving the banker Vorcaro.

matheusmoreira··on OpenAI begins rolling out GPT-6 Astra
I hope they improve their cyber program and make it more inclusive. Not having access to this is extremely frustrating and disappointing.
matheusmoreira··on GPT-6 Astra
Yeah I'm a bit exhausted at this point. I just finished benchmarking GPT 5.6 Sol and Fable 5.0 like two days ago. My data became obsolete literally one day after.

It's never too late to degoogle.

Buy a domain. Get fastmail, proton mail or any other service. Point your DNS to it. Done.

> Though everyone in the world suddenly having a pocket expert hacker should be taken seriously.

I am taking it extremely seriously. That is why I want my own AI models running on my own computers defending it at all times.

matheusmoreira··on GrapheneOS says Pixel 11 has MTE support after all
I've never seen them call it "evil". I've seen them debunk CalyxOS security claims as well as criticism of GrapheneOS, and they usually provide some serious reasoning and technical information when they do it. They know what they're talking about.

Don't take it personally. I'm a huge fan of Linux, and GrapheneOS routinely comes here and calls it a huge security liability. And they are right.

They are good enough to have their own Cellebrite column. If they complain about something, you should probably listen.

Yes.

matheusmoreira··on Claude Fable 5.1 and Claude Mythos 5.1
> they also don't assume I'm developing some kind of nerve agent and lock me out

I'm still having problems with that. OpenAI is a lot less annoying than Anthropic, but I still get obnoxious "this content can't be shown" messages in codex far too often.

matheusmoreira··on Path to Astra: critical capabilities and frontier safeguards
The reason is they keep making public statements like:

> OpenAI is committed to ensuring that the benefits of AI are broadly accessible.

They can't claim that then simultaneously work to keep their cybersecurity models out of reach for non-US citizens like myself.

matheusmoreira··on Claude Fable 5.1 and Claude Mythos 5.1
Switch to OpenAI. I have statistically verified that their plans are good.

  Pro  20x = 60k credits/reset
  Pro   5x = 15k credits/reset
  Plus     =  3k credits/reset

  Pro  20x =  4 * Pro  5x
           = 20 * Plus
matheusmoreira··on Path to Astra: critical capabilities and frontier safeguards
> That means using clear, objective criteria and methods.

For the record, I sent them an LGPD (brazilian GDPR) request for information on all of those supposedly objective criteria and methods they used to reject me from TAC. As a brazilian data subject, it is my right to know that, and to request a review if the decision was made via automated means. Sol itself guided me through this process.

They provided me with neither the information nor the requested review. Sol advised me to escalate to regulatory action.

I'm happy to criticize both. Thank god the chinese are working overtime to undermine US hegemony.
matheusmoreira··on Path to Astra: critical capabilities and frontier safeguards
> OpenAI is committed to ensuring that the benefits of AI are broadly accessible.

Doesn't seem like it. OpenAI will not even allow me to verify my identity for TAC. I have apparently been rejected by a "precheck", possible because of where I'm from.

Even Anthropic allowed me into their cyber program. Anthropic.

matheusmoreira··on Claude Fable 5.1 and Claude Mythos 5.1
But is the model actually going to answer hard questions when we ask them? Or are you going to keep downgrading the models so as to avoid "uplifting" lesser lifeforms like us?
matheusmoreira··on AnkiDroid: Google Play no longer allowing Open Collective donation link
> The "App Store" is just a natural extension of the club.

If by "club" you mean Apple's digital fiefdom.

matheusmoreira··on Cheap GPS jammers are filling the world with navigation dead zones
> boss watching over their shoulder all the time

Sounds like the root cause to me. It should be illegal to use GNSS to track employees, or anyone really.

Jamming is starting to sound a lot like self-defense against surveillance.

matheusmoreira··on Apple caught off guard by AI demand for Mac Mini and Mac Studio
Local inference can't compete with cloud on speed, intelligence and economics. It's all about freedom, privacy, control, sovereignty.

It's about not having to accept any of the stupid "terms" of the corporations. It's about doing things the big labs don't allow you to do, like cybersecurity stuff, or even just chatting with the AI about some wrongthink.

matheusmoreira··on Internet centralization and the original sin of NAT
Regular NAT is not fine at all. It adds needless friction and complexity. Networking is complex and annoying enough without it.

IPv6 just works. DNS gives me the address and that's it, I am now talking to my remote computer.

matheusmoreira··on Internet centralization and the original sin of NAT
> most of the time they are unwanted users trying to break in

Thankfully, we have wireguard now. It drops all packets by default. From the perspective of people who don't have the requisite cryptographic keys, it's like the computer is not even there to begin with.

I've always found it strange how people just put computers out there on the internet and just allow them to interact with total internet randoms. Why are we allowing our computers to talk to strangers? No wonder people are getting hacked.

Yes, and Arch is probably not the right distro for you if you think installing it is a "pain".
matheusmoreira··on Flock CEO's Address Spread Online as Surveillance Backlash Explodes
Reminds me of the "if you don't want people to know, you probably shouldn't be doing it" comment from Eric Schmidt, the Google executive.

It was hilarious and well deserved when people immediately started digging up his dirt in response and exposing stuff like extramarital affairs to the point he had to deploy lawyers. Even before that quote, journalists were using Google itself to search and discover his personal information, and Google's response was to blacklist the journalists. Funny how angry these billionaires get when their privacy gets violated, huh.

It's extremely obnoxious that these big tech executives subject us to surveillance only to turn around and buy back their privacy with their wealth. They should have exactly zero privacy. Doxxing? It's called sousveillance.

It's something you do literally once.
