I've had a Hostinger KVM 4 for a while with 4 vCPUs, 16 GB RAM and 200 GB. My next 2-year renewal is roughly R$130/month, so I started looking for what else I could get for the same price. I originally got it during a Black Friday promotion for around R$55/month dev.to/heymarkkop/should-i-r…

z.ai/blog/glm-5.3 Z.ai just released GLM-5.3, an open-weight model with a notable jump in cyber capabilities. It scores 84.5% on CyberGym, ahead of Anthropic’s Mythos 5 and OpenAI’s GPT-5.6 Sol on vulnerability discovery, although it still trails Mythos 5 significantly on exploit development. The weights are expected in two weeks.

You have Claude Fable for only a few days. Here's how to make the most of it. Introducing /improve: use your most capable model to audit your codebase and write plans for cheaper models to execute later. Studies your code, figures out bugs, perf, tech debt, missing tests, what to build and writes plans any agent can run.

We spent months dreaming and building towards a new place for builders in the island. We’ve executed @eth_floripa with global quality while severely underfunded. We brought founders, anon-hackers, and savvy-nomads to Brazil’s tech-paradise. Now we have a place to host, and I couldn’t be happier with what we are creating here. Thanks for the visit @cioffi_victor, the doors stay open!

Just visited Ethereum Hub in Floripa today. Built by @blockful_io and sponsored by @BaseBrasil_, the Hub was created as a home for builders inside Florianópolis, Brazil’s main startup city. Floripa is extremely founder-friendly. Beyond Ethereum Hub, we also have @Founder_Haus, Hub Primavera, the @moic_digital office, @infinitybase_ House, @SapiensParque, and more. The startup scene here is booming, and I’m excited to keep building alongside it. Thanks for the invite @alextnetto 🫡

Codex 5.3 doesn't always get everything right when coding a feature, but at least gets things done

I wonder how it goes compared to Composer 1.5

Sonnet 4.6 is now available in Cursor. Our benchmarks show it as a notable improvement over Sonnet 4.5 on longer tasks, but below Opus 4.6 for intelligence.

The Codex GUI has been my go-to for everyday coding sessions on hobby projects. I rarely need to go to my personal Cursor. Profissionally I always use Cursor to maximize precision, harness and review. I like the easy checkout/rollback too
