Percolator uses a global…

TL;DR: The how and why of the new 6502 emulator in the chips project.
How do you debug an application, library or an entire system with multiple processes? One answer: tracing. An introduction into bpftrace, and an overview of the Linux tracing ecosystem (DTrace, eBPF, uprobes, etc).

The Linux AIO is designed for, well, Asynchronous disk IO! They are not network sockets, but is it possible to use Linux AIO API with network sockets? The answer is a strong YES!
CockroachDB's consistency model fits somewhere between serializability and linerarizability. We're proposing a new marketing phrase for CRDB's guarantees: no stale reads.
