Four and a half years after Rust officially entered Linux 6.1, with real Apple GPU and NVMe drivers in production and several public conflicts between maintainers, it is time for a sober technical balance. What works, what still costs, and where the next phase is heading.
Continuous profiling with eBPF samples every process's execution stack every few milliseconds without touching the code, then stores the history so you can compare last week's performance with today's. The cost measured in production runs between 1% and 3% of CPU, and it pays off most in databases, API gateways and high-concurrency services.
Installing Docker on Debian 12 means replacing the Debian docker.io package with the official repository: import the GPG key into /etc/apt/keyrings, install the five packages docker-ce, docker-ce-cli, containerd.io, docker-buildx-plugin and docker-compose-plugin, then set log rotation and live-restore in daemon.json before exposing the server to production.
eBPF is a Linux kernel technology that lets you load and run verified, high-performance programs without recompiling the kernel or rebooting the system. It runs safely inside a virtual machine in the kernel and underpins tools such as Cilium, Pixie, Falco, and Tetragon for real-time tracing, networking, and security.
eBPF (Extended Berkeley Packet Filter) is a Linux kernel technology that runs verified programs directly inside the kernel, with no modules and no source-code changes. The kernel verifier rejects any unsafe program before it runs, letting teams monitor system calls, network traffic, and I/O at a much lower CPU cost than traditional external probes.
