The French government does not respect citizens'data. It forces massive centralisation and collection, yet repeatedly fails to keep it safe. Zero real sanctions when the state leaks data while private companies face heavy penalties for far less. Completely unacceptable.

I just ordered my chromium mirror repo. Let’s see how they ship 66G repo on a CD (CD limit is ~700Mb)
We heard you. And we agree. In light of recent developments in physical media, GitHub is proud to announce that you can now obtain your public repo on CD-ROM. Keep it. Lend it to friends. Pass it on to your children. Your code is physically yours, forever. Until you lose it, let's be real. Order yours today. gh.io/cd

Not sure who asked for this, pretty sure it was just the marketing team. At least the CD will have better uptime than GitHub’s actual service 🙃

Couldn’t agree more. As a founder, keeping conviction in what you’re building is everything. It’s easy to get distracted thinking other spaces are better, bigger, easier, etc.
Every piece of advice is a reaction to something that came before. "Validate your idea before you go all-in" was a reaction to MBAs raising millions of dollars based on nothing but a business plan. Today, young builders take that advice and quickly "invalidate" every idea they come up with. Now the missing ingredient is conviction 🤷‍♂️

Proudly announcing PgDog's $5.5M seed round from @BasisSet, @ycombinator, @pioneer_fund, and others. Running Postgres in prod is hard. PgDog is a modern connection pooler, load balancer and database sharder. It can be deployed anywhere and works with all Postgres hosts, incl. RDS Postgres, Aurora, Cloud SQL, Supabase, Neon, etc. Some cool numbers: 2M+ queries per second in prod, 20TB+ sharded, 50+ open source contributors. 1 year down; here's to 10 more.

Today, we're officially introducing the new Vybe. We started as "Lovable for internal apps." We spent the last year building the infrastructure: permissions, integrations, databases, workflows. Everything companies need to actually trust software inside their business. Then, OpenClaw came out and started showing what was possible with agents for personal use cases. Everything clicked for us. The infrastructure we'd built wasn't just useful for humans anymore: it was exactly what agents needed to operate inside real companies and teams. What happens when agents can work 24/7, with the right context, the right permissions, and access to your company's tools? A founder becomes a one-person army. A small team operates like a much bigger one. That's the mission we fell in love with at @vybe_build. Our agents have names and roles. They have their own email, Slack, phone number. They prep meetings, follow up with leads, run ops, update CRMs, build internal tools. Vybe runs on Vybe. We're onboarding 10 teams a week to run AI-native companies.

My advice to founders in 2026: spend tokens, not headcount. Record everything. Make your company queryable. Build self-improving loops. Before long, AI won’t just help you operate your company. It will make it self improving. Don't think AI adoption, think AI transformation. This is the biggest shift in how startups get built since cloud computing.

Biggest red flag I hear from early stage founders? “We’re working on self-serve onboarding” Your product currently requires you to talk to every new customer? That’s a good thing.

Always fascinating how every “we’re going closed source” post comes with a brand new philosophical justification. Nothing wrong with business motives. Pretending it’s not about that is the weird part.
Open source is dead. That’s not a statement we ever thought we’d make. @calcom was built on open source. It shaped our product, our community, and our growth. But the world has changed faster than our principles could keep up. AI has fundamentally altered the security landscape. What once required time, expertise, and intent can now be automated at scale. Code is no longer just read. It is scanned, mapped, and exploited. Near zero cost. In that world, transparency becomes exposure. Especially at scale. After a lot of deliberation, we’ve made the decision to close the core @calcom codebase. This is not a rejection of what open source gave us. It’s a response to what risks AI is making possible. We’re still supporting builders, releasing the core code under a new MIT-licensed open source project called cal. diy for hobbyists and tinkerers, but our priority now is simple: Protecting our customers and community at all costs. This may not be the most popular call. But we believe many companies will come to the same conclusion. My full explanation below ↓

Blaxel is officially a first-class sandbox provider in the new version of @OpenAI Agents SDK. Your agents now have shell, file I/O, and live preview URLs, all running in isolated cloud sandboxes on Blaxel infra. xitter.cf/OpenAIDevs/status/2044…
Replying to @OpenAIDevs
Bring your own environment. The Agents SDK now supports sandbox execution with providers including @Cloudflare, @Vercel, @modal, @e2b, and more. Keep files, credentials, and execution state in your environment while passing approved context to the model.
