Claude Opus 4.7 is now available in Cursor. We've found it to be impressively autonomous and more creative in its reasoning.
We're launching it with 50% off for a limited time. Enjoy!
#1 reason for spaghetti code that's hard to maintain, hard to extend, and buggy is poor separation of concerns.
This happens when implementation details leak outside your objects and too much is shared between them.
Claude Code or other AI agents can't fix this for you no matter how many times you instruct them to follow the principles.
Only a skilled engineer can spot these architectural issues.
Don't skip the fundamentals.
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 ↓
Software engineers don't get paid to write code; they get paid to solve problems.
The faster you realize this, the sooner you'll stop being afraid that AI will replace you and the better your career will be.
My take on Anthropic's new Mythos model:
Don't worry about it. It might be amazing, it might be disruptive.
But there's nothing you can do about it.
Ignore the hype, keep your head down and keep learning, growing and creating.
Adopt this: Relentless Optimism.
So, I cancelled my Claude Max ($200) subscription last month to avoid auto-renew (to try out Codex).
Somehow, my subscription was still auto-renewed yesterday and when I tried to request a refund, the Claude AI support told me I'm not eligible for refund. 🤦♂️
