0x013 - io_uring 🦑
Problem: Syscalls are expensive…
Solution: An I/O model that works uniformly across all file types (!) that provides a general-purpose syscall batching mechanism, which cuts down on context switches and syscalls.
Low-level
Systems and kernel-level trends: eBPF, io_uring, and unikernels, explained for developers who live higher up the stack.
0x00C - eBPF 🐝
Problem: Extending the kernel safely and easily is hard.
Solution: eBPF lets you safely execute bytecode in the Linux kernel without changing the kernel source code or creating a kernel module.
0x005 - Unikernels 🏍️
Problem: You want faster and leaner VMs/containers.
Solution: Compile a slim and performant OS custom-made for your application.
