Super nice day at #KCDPeru #KCDLima 🇵🇪❤️ Everyone here has been so friendly and welcoming - and it was fab to see several talks on #eBPF and @cilium.io!

After 7.5 years, we finally updated the functionality overview in the @cilium.io README 😅

A lot has changed in that time, but the overall vision of the project is still very consistent. We just have a more articulate way to say it now 😀

What makes eBPF exciting for me isn’t just what it can do today, I want to see where it will go in its second decade.

A speaker stands on stage at the Open Source Summit North America, wearing a blue long-sleeve shirt and jeans. The stage features a red and white geometric mountain design in front of dark blue curtains. Audience members are seated and some are taking photos or using laptops. The event branding is displayed on a podium to the right.

A presentation slide at the Open Source Summit North America illustrates the structure of a Linux-based operating system. The diagram is divided into three sections: User Space, Kernel Space, and Hardware. User Space includes “Applications” and “Libraries.” Kernel Space includes “System Calls,” “File System,” “Inter-process communication,” “I/O and device management,” and “Fundamental process management.” The Linux penguin mascot, Tux, appears next to the Kernel Space section. Hardware is shown at the base.
