Hi, I’m Viacheslav 👋
Welcome to my corner of the web where code, systems thinking, and life philosophy meet. I write about GNU/Linux, SRE, Golang, Rust, async I/O, and network engineering.
Projects #
trixter– a high‑performance, runtime‑tunable TCP chaos proxy.tokio-netem– a collection of Tokio AsyncRead/AsyncWrite adapters (delay, throttle, slice, terminate, shutdown, corrupt data, inject data) that power the Trixter proxy and can be used independently in tests and harnesses.cgtouch–vmtouchlike util to show per cgroup per file Page Cache stats.
