I beg everyone in crypto to read this in full. I expected this to be another case of social engineering, likely some recruiter/job offer shit. I was very wrong. And the depth of the operation and personas makes me think they already have multiple other teams on lock. 😳

Um hacker simplesmente hackeou o @cline e instalou o OpenClaw em 4.000 computadores com prompt injection 🫠 Olha que loucura: - O time do Cline criou um workflow de triagem de issues automatizado no GitHub, usando o próprio Claude pra ler e categorizar os tickets - O hacker abriu uma issue com um prompt injection no título — o Claude leu, achou que era uma instrução legítima, e executou - Com isso, ele encheu o cache do GitHub com lixo até forçar a deleção dos caches legítimos de build, substituiu por caches envenenados, e roubou os tokens de publicação do npm - Com os tokens em mãos, ele publicou uma nova versão do cline que parecia idêntica a anterior, só que com uma linhazinha a mais no package.json: "postinstall": "npm install -g openclaw@latest" Resultado: 4,000 devs instalaram o openclaw nas suas máquinas sem saber (aka: um agente com acesso total ao seu computador) 🥲 Muito importante lembrar que IAs não têm malícia e por isso prompt injections são, na minha opinião, a maior vulnerabilidade delas. Resumindo galera: CUIDADO. quem quiser ler na íntegra: thehackernews.com/2026/02/cl…

The number of cancer deaths worldwide has more than doubled since the 1980s. Does that mean we're losing the fight against cancer? Not necessarily, because it depends on how you measure it. On this chart, you can see three ways to look at the same data. The red line shows the total number of cancer deaths. It has increased by about 120%, but this measure doesn't account for the fact that the world's population has also grown enormously over this period. Another approach is to look at the death rate: the number of cancer deaths divided by the total population. That's the brown line, called the crude cancer death rate. It has increased too, but much less — around 20%. But there's still a problem: the world's population has been getting older. Cancer is mostly a disease of old age, so even per capita, we'd expect more cancer deaths simply because there are more older people than before. That's where the method of “age standardization” comes in. It's a way of asking: what would the cancer death rate look like if the age structure of the population hadn't changed? The blue line shows this age-standardized rate: it's fallen by about 25%. At any given age, people are now less likely to die of cancer than they were in the 1980s. The same underlying data gives us three different pictures. The absolute number of deaths is up; the crude rate is up slightly; the age-standardized rate is down. None of these are inaccurate, but they answer different questions. Age standardization is one of the most important statistical methods for making sense of health data. Without it, population aging can hide progress or mask problems.

Every recent Apple device already has the hardware to run this. Assuming we can verify the app is genuine and the device is trusted via App Attest and DeviceCheck, we can prove with hardware-backed cryptographic evidence who created any content, at the exact moment of creation.

It’s an incredibly sad day. I’ve known Bora for a couple of years now and was incredibly blessed to work with her. She has the incredible (and rare, specially in crypto) talent to connect with people. Many people are “famous” in crypto because of their Twitter accounts, their “status”, or some other vanity metric. But Bora is one of the few people that many know for being genuinely kind. If you are looking for someone to do BD at your org, look no further and reach out to Bora!

Today is my last day at @celestia. While I wrap up this journey, my biggest takeaway is that ecosystems don't grow because of noise, they grow as people do. That’s why my focus has always been simple: empower partners to go further. Because when they grow, the infra layer underneath them can grow alongside. I am grateful for everyone at Celestia who helped me grow and learn. I will take the lessons and will always stay focused on the long-term game.

I'm sad to see this update, but it's a giant opportunity for whoever hires him next. ​ ​Luke brings a rare mix of technical experience, video production, and education. It's been a joy to work with him. We shipped great things together, and any team would be lucky to have his creativity. ​Please help share this so it reaches the right team! 👇
TL; DR I was one of the people laid off from @celestia today. I’ve been in tech since 1996. I’ve worked at many places, and one thing I’ve learned is that it’s rare to find a team that really, really clicks. Celestia was that for me. Teams that ship and execute depend on soft skills, trust, and clear communication. We had that… But … while I’m bummed, the silver lining is that we work in a small industry and I have a feeling I’ll cross paths with them again soon. I’ve had a pretty diverse career: engineer, CTO, yoga teacher, owner of a video production company, and now I’ve been in DevRel for the past 3 years. If you’re looking for a DevRel with a strong background in education and video, reach out. I’m in Buenos Aires for a few more days and can meet in person or hop on a call. My schedule is wide open:) Over the past year, @viet_nguyen, @JoshCStein, @web3gb, and I delivered a hackathon, an online training course, and more. Highlights below ->

E abro espaço para apoio em 🇵🇹🇧🇷 também!
Camp Mamo is for everyone. Our bootcamp videos come with subtitles in: 🇬🇧🇺🇸🇨🇦🇦🇺🇳🇿🇿🇦🇮🇪🇸🇬 English (English) 🇹🇭 Thai (ภาษาไทย) 🇪🇸 Spanish (Español) 🇰🇷 Korean (한국어) 🇯🇵 Japanese (日本語) 🇻🇳 Vietnamese (Tiếng Việt) 🇺🇦 Ukrainian (Українська) 🇹🇷 Turkish (Türkçe) We must end the language gatekeeping if we’re serious about onboarding a million devs. That’s why Camp Mamo launches with subtitles in 8 languages, not machine-generated, but manually translated by @celestia validator partners. Build whatever.... in your own language. s/h to our validator partners for helping translate! @contributedao @Cumulo_pro @dsrvlabs @tanelabs @ttt_lab @everstake_pool @node_101

If you are looking for a new role, I highly recommend you to have a chat with Alec!
Replying to @Bitwise
@bitwise is about to take off, and I’m here to help build the team that powers their business. Compounding momentum for years, Bitwise is now one of the largest crypto asset managers, with over $12B in AUM and fresh off a $70M raise from top-tier investors. With regulation easing and real traction in the market, it’s time to double down and grow the engineering team. We’re starting with a Backend Software Engineer role in New York City. You’ll work directly with the CTO (@hongkim__) and other Senior Engineers (@arberx_ @hoanhan101) to rebuild the jobs infrastructure stack that powers Bitwise’s core systems. High-impact work, small team, strong product, no egos. More roles across the stack are on the way. I’ve helped hundreds navigate careers in crypto and HFT. Bitwise stands out — for its mission, its people, and the timing. If you or someone you know is ready to help shape crypto’s next chapter, DM me. Let’s build together at Bitwise.

There's no moving forward without breaking a few eggs. We should be cautious, but not paralyzed. Let’s improve UX and security instead of halting innovation.

🚀 Are you a solidity dev curious about migrating your existing dApp to @rootstock_io? This one is for you! I am back with the articles, and this time, we explore how Linkagotchi evolved into Rootagotchi, combining Ethereum's flexibility with Bitcoin's unmatched security. Here's a quick breakdown! 🧵👇 🌐 Why @rootstock_io ? Rootstock offers EVM compatibility, lower gas fees, faster transactions, and Bitcoin-powered security. It's the perfect destination for scaling dApps while tapping into the Bitcoin ecosystem. 🛠️ Learn more in the article below! 🎮 What is Linkagotchi again(now Rootagotchi)? It's an NFT-based game where players care for and evolve digital pets, and I have created it for the Eth Global Online Hackathon. Moving to Rootstock enhanced speed, reduced costs, and opened new opportunities in Bitcoin's ecosystem. 🐾 Check the code here: github.com/souzavinny/rootag… Check the game here: rootagotchi.vercel.app/ 📖 Read the full story! 🇪🇸 Spanish: medium.com/p/33dcfb376aa0 🇧🇷 Portuguese: medium.com/p/a98079629bf9 🇺🇸 English: medium.com/p/f09cdacd2d45 #Web3 #Bitcoin #Ethereum #Rootstock #DApps #NFTs

Radically simple!
26 Aug 2024
Radically simple ideas bring order to chaos: stacking chairs (brilliant in 1963), flipping a switch (novel in 1933), and ABC order (1st century). Bringing Linux onchain (2023). Cartesi brings radically simple solutions to web3, so developers can do what they do best - Build. 🐧
