⚡ Key Takeaways

• {'point': 'Email-based development at scale', 'detail': 'The Linux kernel uses mailing lists and git send-email instead of pull requests, a workflow that has proven effective for coordinating thousands of developers across hundreds of subsystems.'} 𝕏
• {'point': 'Predictable release cadence', 'detail': 'A two-week merge window followed by seven to eight weeks of stabilization produces a new kernel release roughly every nine to ten weeks, a cycle that has held steady for over a decade.'} 𝕏
• {'point': 'Corporate-funded open development', 'detail': 'Over 90% of kernel contributions come from paid developers at companies like Intel, Red Hat, and Google, demonstrating that commercial involvement and open source principles can coexist productively.'} 𝕏
