Tesla is introducing several cabin climate and HVAC upgrades with the longer-wheelbase version of the Model Y

With the increasing use of AI, expect more security flaws to be trivially exposed.

Great time to review your own setup and ensure it fits your own security model.

@SeedSigner is one of HHW projects that @nvk spent time trashing for years.

A wise man once told me, "I would never use a bitcoin wallet that's not open source."

What if the Coldcard Hacker is just some kid in his parent's basement using AI and checking a public block explorer as part of the exploit?

Hear me out now - the attacker had private keys but didn't steal ALL the funds in wallets - because they don't understand…

I will continue to self custody my Bitcoin!

This Bitcoin hack has only highlighted that we need to take our set ups a lot more seriously!

DO NOT LISTEN TO THE SUITS.

DO NOT LISTEN TO THE FEAR PORN.

CENTRALIZED CUSTODIANS HAVE LOST HUNDREDS OF…

1/A hardware wallet spent years quietly generating guessable Bitcoin keys.

Last week someone drained $38 million from them in about 25 minutes.

The culprit wasn't a hacker. It was bad entropy.

Here's what entropy actually is, why it's so important in self…

11/One rule above all of it: keep the whole ritual off the internet.

Air gapped computer, or at the very least make a throwaway key for practice first.

The moment your seed touches an online machine, the dice were for nothing.

12/That's the whole thing. No trust required. Just physics, a word list, and your own two hands.

You didn't hope the randomness was good. You watched it happen.

Not your keys, not your coins. And not your entropy, not your keys.

El Salvador’s Embassy in Saudi Arabia hosted a cultural workshop introducing traditional pupusas to promote national heritage and strengthen bilateral diplomatic relations.

Bitcoin miners have fixed costs and wildly unpredictable revenue. Hashprice can swing $5–$7 per PH/s in a single month — running roughly 20% monthly volatility, higher than crude oil and about 5x the stock market. In this video, we break down the fundamental…

A multa do INSS por excesso de trabalho existe e mira o aposentado por invalidez. Quem recebe o benefício e é flagrado em atividade remunerada tem o pagamento cessado e pode ser cobrado de tudo que recebeu, com o sistema cruzando carteira assinada e CNPJ…

Existe um andar de shopping onde tudo é mais caro por causa do alvará. A praça de alimentação paga ao condomínio do shopping aluguel percentual sobre o faturamento, fundo de promoção, 13º aluguel em dezembro, e repassa cada linha dessas no preço do combo…

Uma coia que eu não vi ninguem mencionar aqui ainda: e o Dice Roll dentro da própria Coldcard?

Tá supostamente seguro, ou devo assumir vulnerabilidade?

Um dos meus clientes tem um setup com Coldcard Q + passphrase e gerou própria entropia usando a função…

I think the only real solution to AI-assisted cyber exploits is FOSS – real free and open source hardware and software.

Good guys equipped with frontier AI models (without restrictions) to find vulnerabilities in our codebases and in other codebases – and…

Don't throw out your Coldcard devices. If law enforcement can get the coins then your device will likely be needed to prove that you owned the seed.

(this is due to the hardware ID associated with the processor)
