I’ve left Anthropic after more than a year of working on Claude Code and seeing it scale larger than I ever imagined. I have really loved working at Ant and believe deeply in the mission, and most of all, the idea of a race to the top. The idea that if we work hard and responsibly, we can raise the bar and inspire others to great outcomes. And if we all push each other to be better, things can be radically good. I will carry the spirit of this with me forever. My colleagues at Anthropic are the most talented, thoughtful, competent, and earnest people I have ever met. I am glad they are at the wheel and trust them deeply. To the community on X, thank you for everything. You’ve made this the most fun (and sometimes stressful) job I’ve ever had. For me, it is time for a bit of a break before diving into something new. If you want more excellent Claude Code content, you should follow @addyosmani , @lydiahallie, @_catwu, @ClaudeDevs and of course @bcherny who started it all.

Di IG dan TokTik banyak yang bahas issue PHP tapi jarang yg bahas issue SSL eMudhra, padahal dampaknya bisa jauh lebih luas ini daripada yg PHP. Ini saya coba buatkan video penjelasan bagaimana issue SSL eMudhra ini bisa sangat berbahaya.
Kalau kamu buka halaman dv-g3b-emudhra.we-have-a-pro… dan tidak muncul error seperti ini (ERR_CERT_REVOKED) maka browser kamu perlu segera di-update.

October has been an absolute nightmare for software > Railway - customer secrets exposure > LiteLLM - malicious PyPI + Docker releases > Zeabur - infrastructure breached > OpenCode - AI API keys exposed > OVHcloud CLI - official binaries backdoored > Rank Math PRO - malware in official plugin > TeamUpdraft - customer data compromised > ConnectWise - cloud backup identities compromised > Tensorlake - npm package infected > SubQuery - backdoored npm package > GhostAction - GitHub repos with malicious workflows > PHP - critical RCE vulnerabilities > Node.js - security vulnerabilities patched > eMudhra - certificate authority keys compromised > Tailscale - eMudhra incident At this point, the biggest security risk might not be the code we write, but the code we trust...

To put what Espart is doing into perspective, get this: • He starts preseason in the pivot and looks absolutely sublime. A midfielder by trait, and it couldn’t have been more obvious. • Then the season starts. Balde’s situation gets messy, Cancelo arrives late in the window and isn’t sharp yet, and… Flick turns to Espart. Mind you, he’d effectively never played at LB before. Yet, you’d assume he’d spent years there as a seasoned pro. Objectively bonkers from day 1. • Now, for the icing on the cake: an away trip to PSG, an injury crisis at the back, and not a single available RB. Flick, naturally, turns to Espart again. His assignment? Just one of the best left wingers in the world. Arguably the best. Espart proceeds to boss him defensively, then pops up at the other end to score a sublime goal. Because apparently, shutting down his flank wasn’t enough. Are you still with me? Are we appreciating the absurdy of it all? Nineteen. In his debut season…

I'd say ~75% of my issues with AI coding disappeared once I gave my agent the ability to verify its own work

I don’t think we fully appreciate how crazy Anthropic’s original bet was Back in 2024 when OpenAI was doing everything and could do no wrong, Anthropic decides that coding models are the only thing that matters Because being good at coding means recursive self improvement
